For the 1.6 billion people in the world who lack access to electricity, the flashlight serves as a simple but important lighting device. In contrast to traditional incandescent flashlights, incorporating light emitting diode (LED) technology into flashlights presents a potentially less polluting, more efficient and cost-effective alternative lighting source. To avoid market spoiling as LED technology is introduced into off-grid lighting markets it is essential that quality be assured. This study addresses the quality of flashlights available to low-income flashlight users in Kenya. Lab-based performance testing of three commonly used models shows that flashlights perform substantially below rated specifications. Models tested had battery capacities that were 50% below rated levels and required up to 25% more time to charge the battery than advertised. Frequent users of flashlights expressed high levels of dissatisfaction with available flashlights; 87% reported having problems with their flashlight in the last six months. Failed LEDs (23%), water leakage (21%), and batteries no longer keeping their charge (16%) were among the most common problems. The median reported lifespan of a flashlight was two months. Users interviewed indicated that the cost of flashlight ownership absorbed up to 7.4% of their annual income. In addition, the potential health and environmental risks associated with flashlight use are substantial. Estimates indicate that more than 700,000 kg of lead are discarded and over 30,000 m3 of waste are produced annually from the use of low quality flashlights in Kenya. Scenarios illustrating the impact of marketing an affordable, improved quality flashlight indicate a potential 80% reduction of waste and lead disposal and up to a 65% cost-savings for flashlight users. Results obtained from this study are useful for creating a framework for quality assurance of low-cost flashlights products, helping to reduce the social, economic, health and environmental implications of low-cost flashlights in Kenya and elsewhere around the world.

Stormwater runoff from development degrades receiving water bodies and alters their capacity to support life. Environmental planners are tasked with managing impacts from human land uses on ecosystem functions in order to meet water quality goals. However, conventional stormwater management practices aggravate development impacts, raising the need for a paradigm shift in stormwater management. Low Impact Development (LID) approaches to stormwater management can minimize impacts from runoff, and protect water quality and stream ecosystems by mimicking pre-development hydrology. Barriers to adoption, needs, and opportunities for LID on the North Coast of California were assessed through a comparative analysis of the North Coast and four other regions in the United States currently implementing LID. The analysis was based on literature review and on interviews with stormwater professionals in the five regions. The most significant barriers to LID found on the North Coast were institutionalized conventional practices, budget and staff constraints, and challenging local site conditions. The most significant regional needs identified to promote a shift toward LID were economic incentives, education and research, and regulatory and policy reform. Growing ???regulatory-will??? from the state and local level, and significant existing human capital may provide opportunities to help spur LID uptake locally. Recommendations based on my study are that LID policy language be included in General Plans, codes, and ordinances. Standards and requirements for LID should be developed to be consistent on a regional scale. Additionally, local governments should take greater advantage of partnerships with local watershed groups, and universities to create LID educational opportunities.

I evaluated the hypothesis that fruit availability significantly influences stopover habitat quality for fall migrating Swainson???s Thrushes (Catharus ustulatus) in coastal northern California. I analyzed plasma metabolites (triglycerides, ??-hydroxy-butyrate, and glycerol) to assess the condition of Swainson???s Thrushes during migration in two habitats: a native dune forest with abundant fruit (the Lanphere Dunes unit of the Humboldt Bay National Wildlife Refuge) and a riparian habitat with a significantly lower abundance of native fruits (Mad River County Park). In both habitats I collected blood
samples from birds captured in mist nests and quantified dominant vegetation and fruit
abundance in September and October, 2005 and 2006. I used stepwise ANCOVA to
examine the difference in plasma metabolite concentrations between each habitat while
controlling for confounding variables. In support of the hypothesis, ??-hydroxy-butyrate concentrations were significantly higher in birds captured at Mad River County Park than birds caught at Lanphere Dunes, and fruit availability and diversity was lower at Mad River County Park than Lanphere Dunes. Concentrations of triglycerides and glycerol were not statistically different between the sites. Metabolite concentrations were
significantly correlated with several covariates. Triglycerides were positively correlated with minutes since sunrise, date, fat score, and weight. ??-hydroxy-butyrates were positively correlated with fat score but negatively correlated with minutes since sunrise. Plasma glycerol was positively correlated with fat and molt. Further work should couple plasma metabolite analysis with other techniques, such as radio telemetry or sampling of
insect abundance, to more fully examine stopover habitat quality.

Compact fluorescent light (CFL) bulbs offer an economically efficient way to mitigate anthropogenic greenhouse gas emissions through reducing net electricity consumption. This study was aimed at understanding the barriers to the diffusing of the CFL within Humboldt State University???s student body. A representative survey of the Humboldt State University student body was conducted to collect data. The final response rate was 46% and the dataset consisted of 916 responses. Several product attributes were identified as important reasons for not using the CFL. These were product cost, toxicity, compatibility, flickering, humming, brightness, and color quality. Furthermore, issues such as information availability, product location, shopping patterns, worldview, risk perception, significant others, and gender were shown to be significantly related to CFL use. This work concludes by examining an estimate of the total carbon dioxide mitigated by CFL use on campus. This study found that over the next year CFL adopters on campus will offset a conservative 12.443 tons of carbon dioxide.

This project addresses the origins and effectiveness of the political party system in America. The major themes of the scholarly research included in this historiography are that political parties are and have been controversial, that political parties created a dilemma for the founders in terms of weighing faction against liberty, and that a continuing debate exists over the effectiveness of the modern political party system in America. The resulting literature review unearthed a wide array of conflicting interpretations about the efficacy of both the historical and modern political party system. It is clear that author bias and inconsistent research techniques may have influenced the development of the controversy.
This project also includes a unit plan for teaching about the political party system within the larger context of American history. The lesson plan will focus on the early development of our Constitution and what part the issue of political parties took in its evolution.

Rock & Roll burst upon the scene at the same time the Civil Rights Movement picked up momentum in the 1950s. While one might claim this was just a happy coincidence, it was actually a logical progression in music influenced by the same factors pushing the Civil Rights Movement forward. World War II, technology, migration of workers to urban centers, prosperity, and social anxiety of a changing society all affected the development of Rock & Roll and Civil Rights.
Philip Ennis, author of The Seventh Stream: The Emergence of Rocknroll, Alan Dundes, in his book, Interpreting Folklore, and Reebee Garofalo, author of ???Popular Music and the Civil Rights Movement??? all present arguments that music both reflects and influences the social interactions and social movements of a period. Rock & Roll in the 1950s and 1960s expresses the social anxieties of the Civil Rights Movement. Ennis theorizes that Rock & Roll was the natural consequence of World War II and its aftermath as technology forged ahead impacting the arts, economics and politics of post-war America. Popular music actually provides important socio-political indicators of any social phenomenon as it gains national recognition. According to Garofalo, the trajectory of the Civil Rights Movement can be traced through an analysis of trends in popular music from the 1950s through the early 1970s. Changes in musical form, tone, instrumentation, production style, personnel and eventually changes in lyric content reflected social political changes.
Rock & Roll is the derivative of musical forms that originated in the African-American culture and struggle for equality. African American music through the years reflects the institutionalized racial slavery, segregation and discrimination and the struggle for equality. Spirituals, blues, jazz, gospel, rhythm & blues, and country all contribute to Rock & Roll. David Szatmary, author of A Time to Rock: A Social History of Rock ???n??? Roll, ties the development of rock music to the civil rights struggle. The Civil Rights Movement gained strength as coalitions were formed between black churches and secular organizations like the NAACP and CORE. This paralleled the joining of Gospel with Rhythm & Blues to create Rock & Roll. As the Civil Rights movement matured from gaining legal civil rights in the South, through a period seeking a color-blind society and then into Black Power, Rock & Roll was a social barometer to the movement.
In Anti-Rock: The Opposition to Rock ???n Roll, Linda Martin and Kerry Segrave identify the sources of both racial and sexual anxiety as expressed in Rock & Roll. Arnold Shaw, in his book, Black Popular Music in America, furthers the connection of African Americans to Rock & Roll as they gain economic, political and civil rights in the 1950s and 1960s. In Flowers in the Dustbin, Jim Miller delineates conflicts engendered by cultural stereotypes and collective self-expression with freedom as the prize. The threat integration posed to white Americans by the Civil Rights Movement was magnified as Rock & Roll gained popularity with white teenagers. Identifying correlations between the evolving musical style of Rock & Roll and the societal changes, attitudes and expectations engendered through the Civil Rights Movement of the 1950s and 1960s is be the focus of this thesis project.
The second part of this thesis project presents curriculum designed to build empathetic understanding of historical events among incarcerated teens. Teenagers isolated from political, economic and social power, find a sense of group membership and understanding in popular music. The thrust of curriculum development in this project will build on those strengths to engender an empathetic understanding of the struggles, transitions and accomplishments of the Civil Rights Movement with the evolution of Rock & Roll. Building an understanding of the Civil Rights Movement is an important part of the National History Standards and California State History Standards.

Biomass quantification methods have become of increased interest recently due to the threat of climate change. Organizations such as the California Climate Action Registry (CCAR) have suggested the use of generalized biomass equations to quantify forest carbon stocks. However, studies have shown that biomass equation generalization can lead to inaccurate estimates of biomass of live trees. In this study, a mixed evergreen forest type in northwestern California was inventoried and total aboveground biomass was quantified using different types of biomass equations. A new model was developed to predict biomass of bay-laurel trees, which were found to be abundant at the study site. A total of 14 trees ranging from 7.6 ??? 61 cm dbh were destructively sampled. Biomass and dbh were log-linearized and fitted with ordinary least squares linear regression. The bay-laurel equation was used in conjunction with other biomass equations developed in similar geographic regions to quantify stand-level biomass at the study site, which was 292.3 Mg ha-1. This estimate was then compared to the estimate using the biomass quantification methods outlined by CCAR, which was 265.9 Mg ha-1. It was assumed that site and regional biomass equations are the standard method to predict biomass. When compared with the standard method, it was found that CCAR???s equations differed significantly than the standard method and therefore did not accurately predict biomass at the study site.

The southern distribution of the northern red-legged frog (Rana aurora) extends only into the three most northern coastal counties of California and seems to be restricted to the coastal belt. Because of recent declines in the population and destruction of its habitat, the California Department of Fish and Game has declared it a Species of Special Concern in California and it is also federally listed as a Sensitive Species by the US Forest Service. This study investigated the spatial distribution and habitat selection of the species on the North Spit of Humboldt Bay, CA in a locally isolated dune environment. The first part of this study concentrated on natural history facets of the species such as differences in relative abundance, movement, and breeding phenology between and among permanent and seasonal pond-breeding habitats in the study area. The second part of this study described the spatial distribution of the northern red-legged frog within seasonal wetlands of the dune swales using site occupancy models. It also gleaned knowledge on the species??? habitat preferences during the breeding and post-breeding seasons and serves as a baseline experiment for future monitoring of this species distribution. Detection probability was also examined in the egg mass site occupancy models. Frog abundance was greater in the smaller, permanent pond habitat. Movement towards the ponds was greatest during the breeding season in both habitats. Juveniles were most active prior to and during the breeding season, whereas adults were more active during and after the breeding season. Prior rainfall increased movements in both juveniles and adults, although adults were not as affected except prior to the breeding season. No differences in breeding chronology and physical characteristics were found between the habitats. The egg mass occupancy models showed that gravid females preferred oviposition sites with deeper water and less than 50% emergent vegetation. Egg mass detection probabilities were affected by fluctuating water levels throughout the survey period. Egg mass occupancy rates were underestimated when detection was not incorporated into the models. Adult and juveniles in the post-breeding season selected sites with longer hydroperiods that were farther from sites which had contained egg masses. Occupancy results indicate that water depth and hydroperiod length are important factors in determining the spatial distribution of R. aurora in palustrine wetlands, detection probability is an important parameter to include when surveying the species, and the adult and juveniles use more than just the breeding ponds in the wetland habitat. This is the first study to research R. aurora egg mass site occupancy incorporating detection probability. The top model can be used as a foundation to predict egg mass occurrence in palustrine wetlands and as a baseline for development of a larger monitoring program to research spatial dynamics and population fluctuations of the species.

Understanding intraspecific spatial patterns and interactions of American black bears (Ursus americanus) can improve the understanding of social behavior and management of the species. Few studies have examined spatial patterns of American black bears at small spatial and temporal scales. Sixteen black bears (8 females and 8 males) were radio-collared between 27 May and 12 August 2008 in a 175 km2 study area in Humboldt County, California. I measured home range size, overlap, and overlap frequency to describe static spatial patterns (without a temporal component). I measured the spatial and temporal interactions of groups of bears by examining distances between bears and of pairs of bears by examining the use of home range overlapping areas. The mean 95% fixed-kernel home-range estimate was larger for males than for females. Females overlapped other bears with a greater percentage of their overall home range than males. Male home ranges overlapped other bears with a greater frequency than females. According to the spatial and temporal interaction analysis based on distances between bears, bears were not moving in response to neighboring bears. Spatial and temporal interactions occurred for 24% of the pairs of bears utilizing home range overlapping areas, with 18% exhibiting a significant spatial interaction and 6% exhibiting a significant temporal interaction. Although spatial and temporal interactions occurred between eight pairs of bears, spatial and temporal interactions were not detected for 26 pairs of bears in the study area. The lack of significant spatial and temporal interactions
iv
may be a result of high black bear densities. Alternatively, bears within the study area may be interacting at a much finer scale (i.e., within food patches) than this study was able to detect.

A variety of developmental studies programs exist on community college campuses nationwide designed to assist students who begin college lacking the skills necessary to be successful. Learning communities have been used as a curricular structure to help support students??? intellectual, personal, and social growth while they are in college. This study investigated first-year college experiences, from the student perspective, as members of a learning community which featured support services and linked developmental English and learning success courses in a rural northern California community college. Participants included a cohort of first-year college students (N=53) affected by educational, social or economic disadvantages and receiving services from Extended Opportunity Programs and Services (EOPS). A mixed method research design was used including pre- and post-test data collected from the Noel-Levitz College Student Inventory (CSI), a locally developed survey, and focus groups. Major findings suggest that establishing relationships and being able to respond to needed academic or personal support were the most helpful aspects of the EOPS Learning Community. Overall satisfaction with the learning community experience was correlated with student satisfaction with on of the two courses. Differences were also found between learning community completers and non-completers, as those students who completed the courses rated their desire to finish college, family emotional support, intellectual interests, and study habits significantly higher than those students who did not complete.

This thesis is a qualitative examination of the experiences of women who participated in two V-Day initiatives. V-Day is a global organization that stages local initiatives aimed at organizing community members to raise money and awareness to fight violence against women in their communities. Half of the women participated in a college campaign in Northern California in 2007, while the other half participated in a community campaign in the same Northern California community in 2008. A total of twelve respondents participated in hour long, qualitative interviews where they were asked to describe their experiences working in the organization. The women???s stories serve to illustrate and illuminate an analysis of the methods that the V-Day organization uses to successfully organize communities and the role of gender and emotions in V-Day organizing. Also discussed are a variety of concepts stemming from the two main themes that arose from the interviews. First, the concept of empowerment is discussed with consideration of the impact of the participants??? involvement in V-Day on their self-perceptions, as well as their motivation to pursue further activism. Secondly, the concept of solidarity is discussed, with consideration of how V-Day organizing encourages a shared sense of womanhood and contributes to the development of new social networks in the communities that stage V-Day initiatives.

This project looked at ways in which college students use common areas in traditional residence halls. Previous research and theory shows that students??? success is based on both their academic and social integration into a university. For students living on campus, residence halls play an integral role in both.
In Spring 2007, I did a project in a research course which provided the foundation to frame this thesis. Using qualitative methods of site examination, interviews, long observations, and snap-shot observations, I collected information to understand how students use common areas.
After a process of coding and data analysis, the themes that emerged from all the forms of data collection were territorial behaviors, the development of social networks, use of resources, study habits, activities, and multitasking. These themes, in conjunction with previous theory and research, provide groundwork for furthering the design of common areas and implications for further research.

This qualitative research study sought understanding about how former foster youth overcame the odds and completed their educational goals in higher education. More specifically, what personal characteristics and support services assist former foster youth into and through college? Four years ago I was selected to attend the first Former Foster Youth Success Initiative (FYSI) conference in California. The conference was held in an effort to connect 109 California Community Colleges to assist foster youth through the doors of college. What I was able to take away from the conference was that less than 3% of former foster youth graduate from college. After the conference, I was inundated with thoughts, questions, and concerns of my own as to why this population does not finish college. I chose a sample of college graduates because I want to know how this atypical group of former foster youth overcame unbelievable odds to finish college.
This study utilized an electronic survey sent nationwide. The purpose of the survey is to ascertain the characteristics of former foster youth who have been successful in higher education and the supports that helped to promote that success in order to increase the understanding of barriers former foster youth face in higher education and the kinds of support that assist them in successfully completing a degree.

Today, within our current global economy, food has become a target for neo-liberal policies, which has transformed how farmers practice agriculture and the types of food they grow. In the pursuit for free-trade, the world???s food supply has been placed in the hands of transnational corporations, who have pushed for an industrial practice of agriculture in place of traditional knowledge. Today small family farmers and subsistence farmers are being threatened by an industrial practice of agriculture, which has transformed much of the traditional farmlands of the world into large corporate farms for the mass production of cash crops. Neo-liberal policies have allowed corporations to seize the world???s food supplies and place it on the global market to be sold for profit. The result of this has been the displacement of rural peoples to urban centers, increased poverty, starvation and the degradation of our ecosystems.
In opposition to current global food policies, people around the world are rising up in resistance. This resistance comes in all different forms across the globe, but all unify in the injustices of global food policies. One such movement found in the United States, is Community Supported Agriculture (CSA). I have been a part of this movement for the past four years at Redwood Roots Farm, a local CSA, located in Arcata California. While working with Janet Czarnecki, the owner and head farmer of Redwood Roots Farm, we both recognized the importance of educating our shareholders, interns and community on the topics of globalization, agriculture and social resistance. This is when we came up with the idea for an educational guide on these topics. The goal of this project is to educate our community by providing a history of globalization, the institutes that govern global trade, global food policy and those around the world who are in resistance to these policies. From this we hope that our community will have a better equipped to make informed decisions about the food they buy, where it comes from, and the types of food they eat. We hope that this guide can be utilized as a resource as well as an educational tool for workshops on and off of the farm. This project is geared towards adult shareholders, interns and all visitors of Redwood Roots Farm. The greater goal is to make this guide accessible to the general public on how the global economy has transformed food systems around the world

This project began as an investigation of best practices regarding treatment models in order to inform future development of The Emma Center (TEC). TEC is a nonprofit women's center for adult survivors of child abuse, domestic violence, and other traumas located in Humboldt County, CA. Their mission is three-fold: 1) to provide referrals, support, and advocacy to abuse and trauma survivors; 2) to raise awareness in the community about the effects of abuse and integrative, holistic approaches to healing; and 3) to open a women's residential healing center for women recovering from trauma-related conditions. It is with this latter point that my work with TEC has been concerned. A main component of this project is the Best Practices Report which is the result of research looking at several case-studies of organizations appearing similar in vision to that of TEC???s women???s residential healing center. Each case was broken down in a specially designed database by important factors such as treatment philosophy and approach models as well as organizational structure and start-up procedures. Against these models I compare TEC???s goal and mission.
Literature reviews present biomedical frame-works and the provision of services as well as the Empowerment movement and its origins. Since gender-related violence is primarily social, rather than medical in nature, placing this trauma and its subsequent strategies for healing in the context of western disease models is itself problematic. Thus, an approach to healing for women should be rooted in the notion of empowerment, enabling women survivors of gender-related violence to pursue individual and collective strategies for social change in ways that are appropriate to the political and cultural nature of the trauma. The project concludes after a report evaluating TEC. Perceptions of TEC???s current needs, strategies, mission, and goals are looked at in depth. In light of strategic planning processes, I suggest possible adaptations and actions TEC might take in order to keep afloat and moving forward. The project ends with a reflexive statement to support the overall appeal that TEC make the most of the convergence of interests between the community and the individuals they seek to heal, expanding in the direction of social change work toward working toward their high goals.

The men who explored, exploited, and wandered the American West during the first half of the 19th Century were a varied lot. Historians and fiction writers have romanticized the legends, lifestyles, and accomplishments of the first explorers and pioneers of North America???s western lands, but the lives of these individuals were often harder and more harrowing than ever depicted in history books, dime novels, and movie theaters. Washington Irving described the mountain men as leading a ???wild, Robin Hood kind of life,??? and Swiss artist, Rudolph F. Kurz, wrote that these men were ???stared at as though they were bears.??? They were members of military expeditions like Lewis and Clark (1804-06), Zebulon Pike (1806), and Charles Fremont. They were also men like Jedediah Smith and Joseph R. Walker who, as Bil Gilbert states in The Trailblazers, used beaver fur trapping as a way to support their explorations. Noting their variety, William H. Goetzmann, Exploration and Empire, describes most as ???expectant capitalists???, seeking a way to make their fortunes. It was this ???varied lot??? and their dealings with an unknown landscape and peoples that Thomas Jefferson would require if his vision of an American empire extending to the Pacific Ocean were to be realized.
President Thomas Jefferson???s attention became focused on the far west while reading Alexander Mackenzie???s Voyages from Montreal. According to Robert M. Utley???s, A Life Wild and Perilous, it was Mackenzie???s explorations and writings of an overland crossing to the Pacific Ocean that caused Jefferson to consider the idea of the Corps of Discovery and explorations across the Louisiana Territory. The Louisiana Purchase gave no claim to the U.S. of any lands west of the Rocky Mountains, as Jefferson acknowledged. David J. Wishart states in The Fur Trade of the American West 1807-1840 that it was Captain Robert Gray???s discovery of the mouth of the Columbia River in 1792, the Lewis and Clark exploration of 1804-06, and the Pacific Fur Company???s settlement in Astoria from 1811 to 1813 that gave the United States even a tenuous claim on the Pacific Coast region.
It was Britain, Spain, France, and Russia, but mostly American Indian tribes who held the most valid claims to this region. Jefferson was not the only American interested in western lands, in fact, the westward surge of the inhabitants of the American frontier was beyond the control of the combined powers of the federal government as well as the resident Native American populations. As non-citizen Americans, the rights Native American tribes were not considered relevant to the U.S. federal policies nor to the dominant white American and European populations of the day. However, to those white explorers, traders, and trappers who dealt with tribal members on a regular basis, the relations with the native peoples were of paramount importance.
The explorers depended on the resident Indian populations for advice and trade. Trappers and traders often married tribal women and maintained positive relationships with Native Americans. Relationships were not always friendly and newcomers not always welcome. This project seeks to illustrate just how the explorers of Western America related to the Native American tribes and individuals as well as how these early contacts continued to influence those that followed.
As an eighth grade teacher of American history in a multiethnic classroom, I seek out historical events relating to the cultural history of my students. In the conflicts between Native American cultures and European-American culture, my students are often on both sides of this historical debate. The emphasis of curriculum development in this project will build an understanding of the fluid and diverse relationships between western explorers and Native American cultures. This fits within the California State History Standards 8.8 Students analyze the divergent paths of the American people in the West from 1800 to the mid-1800s and the challenges they faced.

The importance of Memphis, Tennessee in the history of popular American music cannot be overstated. If Memphis had produced just the Sun recordings of Elvis Presley in the fifties alone, its status as a city rich in musical tradition would be secure. But there is so much more music that came from Memphis: Johnny Cash, Carl Perkins, Howlin??? Wolf, Roy Orbison, Booker T. and the M.G.s, Otis Redding, Rufus and Carla Thomas, Isaac Hayes, Albert King, Sam and Dave, and Al Green to list just a few.
Memphis helped shape almost all subsequent rock and roll. The synthesis of black and white musical styles that occurred there in the fifties was unique. The Stax recordings of sixties soul music and seventies funk continued Memphis??? history of mixing black and white music together. Perched on the banks of the Mississippi River, the city also deserves credit as a historical locale for blues music, the predecessor of rock and roll. Gospel music helped to define the sound of the music that came from Memphis as well.
This project will attempt to detail the geographic and cultural origins of the different types of music that blended together to become the ???Memphis sound.??? The project will also explore the elements of Memphis that made it such a unique musical petri dish. Why was it that in a city afflicted with racial tension, and in a region stricken with racism, that the musical worlds of black and whites could be fused into new art forms? The presence of gospel, blues, rhythm and blues, rockabilly, country, funk and soul music in Memphis, and its location as a river trading port are important factors that will be explored as well. The importance of Memphis radio, and the individuals who spoke over those airwaves are also vitally important and will be discussed. An entrepreneurial spirit that exists in Memphis and Sam Phillips???s unique vision of racial harmony are also factors that shaped the music, and are parts of the story that will be told. The project will also illustrate the evolution and synthesis of black and white musical styles in Memphis.
A classroom lesson plan is included that explores the importance of not only Memphis, but also other cities that have made important contributions to American musical history. These materials could be used by teachers during their study of the civil rights era, (state standard 11.10, Students analyze the development of federal civil rights and voting rights). Teachers might also find it useful when teaching the culture of the fifties, sixties or seventies (state standard 11.9, Students analyze the economic boom and social transformation of post World War II America in terms of: forms of popular culture with emphasis on their origins and geographic diffusion).
Using both primary and secondary documents, as well as the wealth of recordings from Sun, Stax and Atlantic studios, conclusions about Memphis??? cultural uniqueness and contributions to the history of American music will be made.

School readiness is the result of children???s direct and indirect interactions with
environmental resources, and it is through those social relationships between children, peers, families, and teachers that children come to acquire the academic, language, and social emotional skills that prepare them to enter school. The purpose of this study was to investigate the thoughts, ideas, and beliefs fathers have about being involved in their pre-school children???s education. A review of the literature indicated that the topic of school readiness would benefit from the addition of
information from this particular population. I contacted preschools in the local area
as a venue through which to recruit fathers of children who were currently attending
the preschool. Sixteen fathers responded and completed the questionnaire, providing
information on their backgrounds, school readiness activities in which they engaged
with their children, father/school interactions, barriers and support systems they had
in place in regard to their relationship with their children and their priorities for their
children.

The following research addresses the question: does color vision occur in animals that can only see rudimentary images? Since the morphological and neurological requirements of color vision are minimal relative to those necessary for image formation, theoretically, color vision should be accessible to organisms with negligible ability to form images. I have designated and refer to such putative animals as Negligible Image Color Eye (NICE) animals. Despite the theoretical likelihood of NICE animals and the excellent potential they present as model systems for studying adaptive evolution of opsin, there is a striking dearth of wavelength-specific behavioral research on animals with negligible image-formation.

The following research addresses the question: does color vision occur in animals that can only see rudimentary images? Since the morphological and neurological requirements of color vision are minimal relative to those necessary for image formation, theoretically, color vision should be accessible to organisms with negligible ability to form images. I have designated and refer to such putative animals as Negligible Image Color Eye (NICE) animals. Despite the theoretical likelihood of NICE animals and the excellent potential they present as model systems for studying adaptive evolution of opsin, there is a striking dearth of wavelength-specific behavioral research on animals with negligible image-formation. And, behavioral evidence of color vision has not previously been established in an animal with negligible image-formation capacity.

Previous research has shown that our attention is often predisposed toward certain external stimuli in our environment. Studies using a form of the Stroop color-naming task have measured significant attentional bias in individuals toward certain stimuli when that stimuli resonates emotionally with an individual???s trauma or pathology. In this study, 40 smokers either abstained or continued their regular smoking habits for a 24 hour period. Participants then viewed an emotional Stroop task where they were asked to name the colors of neutral or smoking-related words presented on a computer screen. A literature review of studies involving smoking abstinence revealed certain risks to smokers who stop smoking for brief periods of time. These risks include feelings of anger, nervousness, and anxiety as well as increased hunger for sugars, fats, and carbohydrates. Participant benefits include physiological reductions of heart rate and blood pressure. Additionally, certain participants may have discovered personal benefits arising from their temporary smoking abstinence and chose to cease their smoking habits altogether.

The science of immunology, for much of its history, has focused on the ability to induce the biological acquisition of specific immunity or on the ability to produce specific immune agents. Examples are, respectively, vaccinations that enable vertebrate animals to become completely immune to a specific microbe, and production of specific antiserums and antibodies that can be used to directly treat illness, or to study cellular biology. In modern times a new appreciation for non-adaptive immune measures, a.k.a. innate immunity, has begun to emerge. It has become increasingly clear that non-adaptive measures carry out a massive portion of the work done in keeping multicellular organisms immune. This work includes the quintessential functions of self/non-self recognition and initiation of adaptive responses. In the last ten years the nematode worm Caenorhabditis elegans has begun to be used as an effective model organism for the study of innate immunity. It has been shown that this worm engages in recognition of pathogens via pathogen associated molecular patterns (PAMPs), that it uses conserved cellular signaling pathways during its immune response, that it constitutively produces conserved microbicidal measures, and that it responds to infections by inducing expression of conserved microbicidal effectors. In the current study I have exposed C. elegans to the bacterial pathogen Burkholderia thailandensis, which is a nearly identical pathogen to the causative agent of the human disease Melioidosis (Burkholderia pseudomallei). I did this in an effort to shed some light on the nature of this infection. Specifically, I exposed C. elegans worms to living bacteria and to bacterial exometabolites. I then measured the expression of genes known to be involved in the worm???s immune function. In addition, I compared the CS????-type (defensin-like) peptides of this worm to putative protein sequences from the human genome and discovered a high degree of identity in some examples. My results show that the worm is responding immunologically to B. thailandensis and that this microbe???s exotoxic effects are having direct impact on the worm???s expression of at least one CS????-type peptide. In addition, my results suggest that there may be a class of CS????-like peptide that has been previously uncharacterized.

This project was designed to assess if the California Native Plant Society Vegetation Monitoring Program (CNPS VMP) provides habitat data useful for predicting bird distributions. In 2004-2005, point counts for bird occurrences and relev?? vegetation surveys following the CNPS VMP protocols were completed in the Sierra Nevada foothill blue oak (Quercus douglasii) woodlands of Yuba and Nevada Counties, California. Bird occupancy models were built in program PRESENCE using CNPS relev?? data for twelve birds listed as focal species in the California Partners in Flight document The Oak Woodland Bird Conservation Plan. For nine species, site occupancy (??) and probability of detection (p) showed strong associations with CNPS relev?? covariates. Estimates of occupancy that accounted for imperfect probabilities of detection were generally 20-30% higher than na??ve estimates of occupancy for each bird. The results show the CNPS relev?? data include important habitat variables useful for species-specific explanatory bird occupancy modeling within Sierra Nevada foothill hardwood rangelands. Further work should focus on the evaluation of existing models as well as on the development of new occupancy models for birds in different habitats using the CNPS vegetation monitoring program data.

To obtain the most complete understanding of a species??? life history requirements, one must know what habitat characteristics and resources are critical to each life history stage. Rana boylii are known to associate with various stream habitats throughout their life cycle, and these habitat associations may vary based on changes in age, season or both. In this study I looked at meso-scale habitat use and resource use among adult, sub-adult, and metamorph R. boylii on Red Bank Creek, Tehama County, California during three seasons using visual encounter surveys.
For each age class the proportion of habitat used was compared to the proportion of habitat available to see if habitat selection existed. The proportions of each age class observed in each of the four habitat types over time were also compared, to determine if habitat differentiation existed between age classes or seasonally. The results indicated that adults and sub-adults generally used different habitat than metamorphs, but metamorph habitat use changed seasonally. Adults and sub-adults showed a preference for pool and riffle habitat, whereas young of the year metamorphs selected for slower moving glides and runs. However, after metamorphs had overwintered they selected for riffles. These results suggest R. boylii exhibit natal site fidelity.
Diet data were obtained using a procedure known as gastric lavage. The results of the diet analysis indicated that all age classes of R. boylii consume terrestrial insects. There were no significant differences in the taxonomic groups of insects found in the diet samples of different age classes. There was also no significant difference in mean prey size for different age classes. However, the results suggest that R. boylii are gape limited predators, since larger frogs consumed a greater proportion of large prey items. This lack of a significant result could be due to sample size.

In a society that appears to be growing more accepting of lesbian and gay people, where prominent individuals can speak more openly about their sexual orientations without fear, there appears to be a growing societal acceptance of non-heterosexual people. Can this growing tolerance be applied to parental relationships with their own lesbian and gay children as well, and does this acceptance of gay and lesbian culture apply when it hits closer to home?
This thesis attempted to research perceived parental relationships following the disclosure of sexual orientation by lesbian, gay, bisexual female, and bisexual male offspring. The first hypothesis was that parental relationships with their lesbian, gay, and bisexual offspring will be perceived by offspring as more negative following disclosure of sexual orientation than before disclosure. The second hypothesis was that parental relationships with lesbian and bisexual offspring following disclosure of sexual orientation will be perceived by offspring as more positive in comparison to relationships with gay male offspring following disclosure. Furthermore, the third hypothesis was that parental relationships with lesbian, gay, and bisexual offspring will be perceived by offspring as more positive as the length of time since disclosure increases.
The Parental Attachment Questionnaire (PAQ), designed by Maureen Kenny, assessed perceptions of current relationships with parents. Two questions assessed perceptions of relationship with parents before and immediately following disclosure of sexual orientation in comparison to the present time. A paired-samples t test comparing the mean scores before disclosure and immediately after disclosure revealed that there was a significant difference between scores before and scores immediately following disclosure, indicating that participants in this study perceived their relationships with their parents as significantly worse immediately following disclosure than before disclosure.
There were no significant differences between the four groups on scores on the Parental Attachment Questionnaire. Although research suggests that the ???coming out??? experiences of lesbians, gay males, and bisexuals may differ, support for this hypothesis was not found in this study.
A small but significant positive Pearson correlation was found between length of time since disclosure and Composite, Subscale 1 Affective Quality of Relationships, and Subscale 2 Parents as Facilitators of Independence, scores on the PAQ. A small but significant positive Pearson correlation was also found between age and Composite, Subscale 1, and Subscale 2 scores on the PAQ. A significant Pearson correlation was found between age and length of time since disclosure. No significant correlations were found between age at time of disclosure and composite or subscale scores on the PAQ. An examination of partial correlations statistically controlling for age as a covariate revealed that time since disclosure was no longer correlated with composite scores on the PAQ, or any of the subscales. The results found when controlling for age as a covariate indicate that perceptions of a better may be a result of other age-related factors rather than the time since initial disclosure. This study did not find support for the hypothesis that relationships will improve as the length of time since disclosure increases, however, the findings here indicate that perceived relationships do improve, though identifiable reasons for which were not found here.

In a society that appears to be growing more accepting of lesbian and gay people, where prominent individuals can speak more openly about their sexual orientations without fear, there appears to be a growing societal acceptance of non-heterosexual people. Can this growing tolerance be applied to parental relationships with their own lesbian and gay children as well, and does this acceptance of gay and lesbian culture apply when it hits closer to home?
This thesis attempted to research perceived parental relationships following the disclosure of sexual orientation by lesbian, gay, bisexual female, and bisexual male offspring. The first hypothesis was that parental relationships with their lesbian, gay, and bisexual offspring will be perceived by offspring as more negative following disclosure of sexual orientation than before disclosure. The second hypothesis was that parental relationships with lesbian and bisexual offspring following disclosure of sexual orientation will be perceived by offspring as more positive in comparison to relationships with gay male offspring following disclosure. Furthermore, the third hypothesis was that parental relationships with lesbian, gay, and bisexual offspring will be perceived by offspring as more positive as the length of time since disclosure increases.
The Parental Attachment Questionnaire (PAQ), designed by Maureen Kenny, assessed perceptions of current relationships with parents. Two questions assessed perceptions of relationship with parents before and immediately following disclosure of sexual orientation in comparison to the present time. A paired-samples t test comparing the mean scores before disclosure and immediately after disclosure revealed that there was a significant difference between scores before and scores immediately following disclosure, indicating that participants in this study perceived their relationships with their parents as significantly worse immediately following disclosure than before disclosure.
There were no significant differences between the four groups on scores on the Parental Attachment Questionnaire. Although research suggests that the ???coming out??? experiences of lesbians, gay males, and bisexuals may differ, support for this hypothesis was not found in this study.
A small but significant positive Pearson correlation was found between length of time since disclosure and Composite, Subscale 1 Affective Quality of Relationships, and Subscale 2 Parents as Facilitators of Independence, scores on the PAQ. A small but significant positive Pearson correlation was also found between age and Composite, Subscale 1, and Subscale 2 scores on the PAQ. A significant Pearson correlation was found between age and length of time since disclosure. No significant correlations were found between age at time of disclosure and composite or subscale scores on the PAQ. An examination of partial correlations statistically controlling for age as a covariate revealed that time since disclosure was no longer correlated with composite scores on the PAQ, or any of the subscales. The results found when controlling for age as a covariate indicate that perceptions of a better may be a result of other age-related factors rather than the time since initial disclosure. This study did not find support for the hypothesis that relationships will improve as the length of time since disclosure increases, however, the findings here indicate that perceived relationships do improve, though identifiable reasons for which were not found here.

Advocacy in the humanitarian field has historically taken a back seat to relief operations, and for good reason: the central imperatives governing humanitarian action???access (to populations in need) and security (of one???s teams in the field)???also limit humanitarian advocacy. Bedrock humanitarian principles such as neutrality, impartiality, and humanity ensure that humanitarian interventions are non-political (impartial), but also limit the scope of political activities like advocacy available to relief NGOs. This international division of humanitarian labor???with relief NGOs focused on needs-based assistance while political actors focus on the political work of resolving crises???has been unraveling in the post-Cold War world, forcing the relief community to reconsider its relationship with political action and its engagement with the so-called political world. This study argues that humanitarian advocacy is now indispensable to humanitarian action, and that relief NGOs must view advocacy as a vehicle for ???operating in broader political arenas, while maintaining the core values of humanity and impartiality that make humanitarianism a distinct and valuable form of politics??? (Leader 2000: 4). The relief community can no longer limit itself to service delivery alone: investing in advocacy is the only way to safeguard humanitarian values, effectively engage political actors, and ensure humanitarian outcomes for vulnerable populations around the world.

The goal of the current study was to examine implicit and explicit attitudes toward homeless people. More specifically, it was addressed how these attitudes were related to contact experiences with homeless people, measured in terms of exposure that was based on the amount of various forms of direct and indirect contact with homeless people and contact quality which was based on whether the contact was positive or negative with homeless people. It was hypothesized that more contact, in terms of both exposure and quality, would be associated with more positive implicit and explicit attitudes toward homeless people. Research is mixed regarding public attitudes toward homeless people, with some reporting generally positive attitudes, but other work finding negative attitudes. The discrepancy between these findings might be explained by social desirability effects that are often present with the use of explicit attitude measures. Implicit measures are not susceptible to such effects. In addition, implicit measures have been found to be better predictors of some social behaviors than explicit measures.
In this cross-sectional, correlational study, exposure to homeless people related to explicit but not implicit attitudes. Similarly, contact quality was only linked to explicit attitudes. The interaction between exposure and quality predicted neither attitude. These results are consistent with research on the positive association between contact and explicit attitudes toward homeless people and different ethnic groups that have found a positive relationship between contact and attitudes. Results suggest that contact with homeless people may be beneficial to fostering positive attitudes toward homeless people, and that even negative contact with homeless people was found to relate to positive explicit attitudes toward them.

Although most studies show a correlation between a prison inmate???s participation
in post-secondary education and a reduced tendency to recidivate, or reoffend once he is
released, little evidence exists to show a causal link between the two. Yet, correctional
education literature primarily utilizes recidivism as a measure of program success. Few
researchers direct their attention toward alternative criteria to evaluate program success or to acquire the inmate perspective of what works. This study explored a California community college academic distance learning program at a California maximum security prison for men. The researcher analyzed data gathered from student interviews and grade reports to determine inmates??? perceptions of the effect of the college program on attitudes, behavior, and academic achievement. Inmate students praised the prison for enabling them to bring meaning to their lives, even in the most restrictive of
circumstances, with a program which could potentially impact the entire prison culture.

Although aural learning and improvisation of music have been fundamental components of music learning theories for at least two hundred years, published resources for beginning instrumentalists usually take a notation-first approach. An analysis of popular beginning band method books published in the last six years further reveals an emphasis on the teaching of techniques necessary to play music in the Western classical tradition, an emphasis which might influence instrumental teachers' values and teaching approaches. An alternative approach in beginning instrumental music instruction emphasizes improvisation and the development of music listening and speaking vocabularies prior to the development of music literacy. Jazz offers an ideal medium for this exploration, as improvisation is integral to this art form, and it is a genre outside of the Western Classical tradition.
The call to incorporate improvisation and jazz into the beginning instrumental curriculum will necessitate the revision of current curricula, the adoption of new learning goals, and the development of additional teaching strategies. This project aims to help fill this void and to make improvisation and jazz available to all instrumentalists through the creation of a jazz-based beginning band improvisation curriculum unit for grades 5 through 8. The unit that is the content of Chapter Four of the project meets the National Standards for Arts Education improvisation content standard and can be taught within the typical time constraints of beginning instrumental instruction in a school setting.

The Great Gray Owl (Strix nebulosa) is listed as a State of California endangered species due to their low population of approximately 100 individuals. Annual surveys and long-term monitoring efforts are frequently conducted to determine the status of this species within its very limited range in the Sierra Nevada. Great Gray Owls are difficult to study because they are rare, nocturnal, and secretive. I investigated two bioacoustic techniques that may be useful to incorporate into current survey protocols and monitoring efforts of Great Gray Owls: (1) vocal individuality, and (2) the use of autonomous recording units (ARUs).
To investigate the potential of individually distinct vocalizations for population monitoring, I recorded the territorial calls of 14 male and 11 female Great Gray Owls between March and July 2006 and 2007. Nineteen of these owls were recorded on multiple occasions within a season, and eight owls were recorded on separate occasions between seasons. Seventeen frequency and 15 temporal variables of the calls were analyzed from 312 sonograms. A stepwise discriminant analysis selected the nine best discriminator variables and correctly classified 92.8% of the calls to the correct individual within a season. Between seasons, 71.4% of the calls were classified to the correct individual. My results indicate that territorial calls could be used to monitor individual Great Gray Owls for both short and long-term studies.
To investigate the use of autonomous recording units (ARUs), I installed ARUs in 15 potential Great Gray Owl territories from March to July 2006 and 2007. Each unit recorded 12 hours per night (from 1800 to 0600). Great Gray Owl vocalizations were successfully recorded at 10 of the 15 territories. In locations where owls were detected, audible calls were recorded during 49.5% of the nights sampled. Recorded chick calls late in the breeding season were the loudest and may be the most useful indicator for owl presence and nest success. Adult territorial calls recorded by ARUs could also be analyzed for vocal individuality. A combination of ARUs and vocal individuality would be useful as a relatively non-invasive procedure to improve census estimates and yield information on distribution, site fidelity, turnover rates, reproductive success, and behavioral traits of Great Gray Owls in the Sierra Nevada and in other parts of their range.

My work is a comparative/ historical analysis of the Armenian Genocide, and how the denial and treatment of this genocide by Turkey and the United States has affected the social psychological wellbeing of succeeding generations of Armenians. I explore the literature that documents Turkey???s denial of the Armenian Genocide, and I also consider the United State???s political stance (or lack there of) on the denial.
I use historical sources (i.e. books, videotapes, scholarly journals, etc.) to compare the Armenian Genocide with other genocides (i.e. Jewish Holocaust, Rwanda, etc.), and I look specifically at the reasons behind the state-sponsored killings, methods of murder, and who were the killers. The majority of my thesis covers the Armenian Genocide, detailing what happened, how it happened and why it is denied. I draw on genocide studies and literature of the Armenian genocide. I use literature on collective memory/ collective identity in order to theoretically demonstrate ways in which collective knowledge and identities are formed.
One Purpose of my thesis is to concisely draw together literature that recognize the reality and effects of the Armenian genocide. The International community is faced with overwhelming evidence proving the Armenian Genocide happened and was in fact State-sponsored under the Ottoman Empire???s Turkish government. Even in the face of hundreds, if not thousands of survivor testimonies, archival photographs, documentation of first-hand eyewitness accounts by diplomats, missionaries, and reporters, there is still political and academic silence around discussion of the Armenian Genocide. The second purpose is to join my personal biography as a second generation Armenian American with the sociological imagination in order to shed light on Turkey and the United States??? shared role in the distortion of history. Lastly, I draw on social movement literature in order to briefly document the developing international effort calling for the Turkish government???s recognition of the Armenian Genocide.

The International community is faced with overwhelming evidence proving the Armenian Genocide happened and was in fact State-sponsored under the Ottoman Empire???s Turkish government. Even in the face of hundreds, if not thousands of survivor testimonies, archival photographs, documentation of first-hand eyewitness accounts by diplomats, missionaries, and reporters, there is still political and academic silence around discussion of the Armenian Genocide. The second purpose is to join my personal biography as a second generation Armenian American with the sociological imagination in order to shed light on Turkey and the United States??? shared role in the distortion of history. Lastly, I draw on social movement literature in order to briefly document the developing international effort calling for the Turkish government???s recognition of the Armenian Genocide.

With schools under increasing public scrutiny and political pressure to show evidence of improved student achievement, leadership must emerge to sustain healthy school environments for teachers and students. The drive for school reforms should not overlook the leadership potential of classroom teachers, perhaps best positioned to make meaningful changes. This mixed-method study sought to fill a gap in the literature by measuring the degree of classroom-based teacher leadership evident in 56 teachers at three public elementary schools in Northern California. Through a synthesis of the literature, 25 subscales of classroom-based teacher leadership were developed and organized into five constructs: Focus on Student Achievement and Relationships, Initiating and Taking Risks, Trust, Collaboration, and Traditional Leadership. The constructs were assessed though teacher surveys and interviews.
Statistical results were explained through themes that emerged from the interview data, suggesting supports and barriers to teacher leadership. An important finding was predictability of the constructs, whereby a high degree of teacher leadership in one construct predicts a high degree in another. The most correlated of the five, Collaboration is also the most visible construct in schools, and may be a reliable indicator of a school???s overall teacher leadership.
The study???s most significant finding is the fundamental requirement of candid, two-way communication for teacher leadership to flourish. More than merely supportive, an open and healthy school climate is critical to the survival of teacher leadership. It is what allows teachers to live effective, professional lives, and creates the potential for schools to support superior student outcomes.

The purpose of this project was to develop a tool that would lead to a more positive transition experience into special education for students with autism and their families. After interviewing parents of students with autism and researching the literature, a Parent Needs Assessment was developed, which includes a checklist of parents??? needs and priorities for their child. The Assessment provides a means for special education staff to understand the needs of the family during the transition period, and ultimately leads to a more effective education for the student with autism.

Four reading intervention strategies that are research validated and have demonstrated the likelihood to improve students??? oral reading fluency and comprehension are: repeated readings, phonics instruction, vocabulary preview/review, and guided reading. Brief experimental analyses of oral reading fluency were conducted with seven elementary students who are experiencing difficulties in learning to read. A reading clinic model served as fieldwork experience where pre-service teachers learned how to apply a sequential application of specific reading interventions. Following a baseline condition, instructional treatments were combined with prior conditions until there was improvement in oral reading fluency in the instructional passages. The purpose of this study is to evaluate the critical features for a quality reading clinic. Pre-service teachers will determine what components of the reading clinic were beneficial and most effective in their preparation to teach reading. The results of an open-ended questionnaire and a survey given to the pre-service teachers are an important basis for interpreting the findings.

This study examined the ability of the closed gibney with heel locks and figure-of-eights, and the cotton ankle wrap applied using the Louisiana technique followed with an overlay of athletic tape in the same manner in their ability to limit ankle supination during a maximal vertical jump. For this study, 12 athletes from the 2001-2002 Humboldt State University intercollegiate men???s basketball participated. Data was collected using 2D motion analysis software. A repeated measures ANOVA adjusted for multiple comparisons with a Post Hoc Bonferroni was utilized to analyze the differences between the baseline (no ankle support applied), pretest (with the application of support), and posttest (after 15 minutes of exercise) measurements for each of the two testing conditions.
The data showed the closed gibney significantly reduced ankle supination from the baseline to the pretest measurements (p = .001). While no significance existed between the baseline to the posttest (p =.098), there was significance between the baseline and posttest (p = .003). The cotton ankle wrap showed significance between the baseline and pretest (p = .002), the pretest and posttest (p = .024), and the pretest to posttest (p = .009) measurements. Comparing the two testing conditions showed no significance between baseline (p = 1.00), pretest (p = 1.00), and posttest (p = 1.00).

An evaluation of the Humboldt County Juvenile Detention Risk Assessment Tool was conducted. Those probation officers that use the tool were interviewed to determine if all of the parts of the tool are functional and if the tool is operating as it is supposed to be operating. The interview questions focused on the methods in which the probation officers fill out the tool, as well as focusing on the officer???s attitudes toward the tool. It can be concluded from this evaluation that the tool would operate effectively if more uniformity existed in the way in which the tool is filled out. This can be accomplished by formulating policies on how to address certain sections of the tool.

In the 20th century U.S. farming began to change its structure from an autonomous structure to a co-dependent, and highly industrialized structure. Industrial farming pushed many farmers out of business, as they were unable to stay on the ???tread mill??? of production that necessitated technology inputs and vast acreages to net larger yields for a meager return at the commodity market. Many farmers and their families were displaced into the neighboring cities and town to seek out work, often times in the burgeoning service sector that developed in the years after World War II. As a result, farmers and farming communities lost their connection to the land as the farming process became alienated from its producers and consumers. Urbanization increased and the remaining farms in the peripheries of urbanizing cities were increasingly in danger of being supplanted by urban development. Rising land valuations and taxes have made it difficult for farmers to continue their operations, leading to further displacement. As a result of the stated factors of displacement, many farmers began to rethink their modes of operation by reinventing the farming process. For the respondents in this study, that meant creating a sustainable form of agriculture that would help them stay viable, and more importantly maintain their culture.
The primary point of this research is to better understand the current state of the changing form of agriculture taking place in Eastern Nebraska. Essentially, How are the expanding suburban peripheries affecting the farms? What are the farmers doing to maintain their viability? How can they increase their viability through sustainable practices?
The local food movement occurring in Eastern Nebraska is a step closer to sustainability; the process of responsible stewardship in land maintenance, farm practice, and reconnecting with the community. I begin the paper with a brief history of U.S. agriculture that has brought forth the exacerbated industrial structure. The paper then proposes how social capital may create a viable connection between the farmer, consumer, and service sector that may ensure a cooperative network system benefiting all.
This qualitative research involves 30 interviews with small niche market farmers, specializing in produce, fruits, dairy, meat, and a variety of mix-use goods. The study found that these farmers are experiencing some of the same displacement factors affecting the larger commodity farms: rising land and tax valuations, input costs, and cultural differences among farm and non-farm neighbors. The paper concludes with some recommendations that may aid the local food movement to become more sustainable and most importantly, increasing farm viability for future generations.

Taylor Creek is located in the Lake Tahoe basin and drains into Lake Tahoe. A beaver colony in Taylor Wetland has built 14 dams along Taylor Creek and in the wetland, creating nine beaver ponds upstream. All of the dams in the main channel of Taylor Creek are destroyed annually in early fall by United States Department of Agriculture Forest Service to allow kokanee salmon (Onchorynchus nerka) to spawn. In addition, flows from Fallen Leaf Dam, located upstream of Taylor Wetland, are increased to supply ample flows for spawning (United States Department of Agriculture 1981). To determine whether beaver activity, specifically the creation of beaver dams and ponds, improve water clarity by reducing the amount of total phosphorus entering Lake Tahoe, water samples were taken before and after beaver dam removal at sites upstream from beaver influence (control sites) and downstream from beaver pond sites (impacted sites). Results were analyzed using multiple linear regression models and mixed-effect models with site random effects for intercept and covariate coefficients. The mean total phosphorus concentration for control sites before and after dam removal was 51.0??g/l and 64.5??g/l, respectively. The impacted sites increased from 70.4 ??g/l to 170.5??g/l (p =
0.1517). This study implies that the presence of beaver ponds in Taylor Creek could improve water quality by reducing the phosphorus load entering Lake Tahoe when flows are increased from Fallen Leaf Dam.

The major questions involved in this research center around the relationship between three self-identified subgroups of American Indians: (a) traditional, (b) bicultural, and (c) assimilated. This is an important issue because of this relevancy to college success for American Indian students. Four hypotheses were asked regarding perceived cultural values and reported perceived ego identity, self-efficacy and social distance and traditional, bicultural and assimilated American Indians. The participants completed a brief Demographic Questionnaire and a self-identified cultural checklist as to whether
they identified themselves as traditional, bicultural or assimilated American Indian. In
addition, they completed a Semantic Differential for Native Values, Erickson???s Ego Identity Scale and Coppel???s Perceived Self-Efficacy as well as the Modified Social Distance Test for American Indians. It was proposed that self-identified traditional American Indians would score significantly higher in American Indian cultural values, stronger ego strength, with higher levels of perceived self-efficacy as well as report less social distance than would self-identified bicultural and assimilated American Indians. The results of one-way ANOVA and LSD post hoc test found no significant difference in the three groups for American Indians values; however, traditional American Indians reported significantly higher ego-strength and perceived self-efficacy but lower social distance which was not significant. It was concluded that it might be that bicultural and assimilated American Indians experience cultural needs, while traditional American Indians experience the luxury of cultural distance. Some of the differences found here may suggest that not all individuals classified as American Indian have the same educational problems. Educators might better plan for the American Indian student if they become aware of how these differences affect learning style, classroom performance, and a sense of competence.

Cohousing originated in Denmark in the 1960s and, after much success, spread to North America in the 1980s. In the United States, the 1980s marked a period of ever-increasing suburbanization. With this shift in neighborhood organization came a related perceived loss of community. Some people who felt alienated from their neighbors and unsatisfied with typical housing opportunities turned to cohousing. These people hoped to find solutions to ???community lost??? by living in cohousing developments whose aims included creating safe ???fifties style??? neighborhoods that promoted the well-being of residents through shared common spaces and community decision making.
This research is an ethnographic study of a cohousing community, referred to in this paper as Emerald Hills, established in 1998 in a small town in Northern California. I entered the setting in Spring 2005 and exited the community at the end of the year. In addition to participant observation at community meals and meetings, I completed fifteen one-on-one semi-structured interviews. In those interviews, I encouraged participants to speak about their cohousing expectations and experiences and questioned them about relationships with others in the community and the emotional aspects of their experiences.
I used NVivo qualitative data analyis software to analyze field notes and interview transcriptions and reviewed the data looking for common themes and coded accordingly. To analyze the data, I relied on the existing literature on cohousing, well-being, social interaction, social support, individualism and expectations.
Participants developed a sense of well-being at Emerald Hills through regular community meals, community projects, shared political outlooks, friendships with neighbors, a good environment for raising children and other resources from those relationships. Conversely, conflicts over money, the absence of mediation and consensus training, the lack of a unifying vision statement, individualism and disagreement about expectations for relationships among community members negatively affected the well-being of residents of Emerald Hills. However, those community members with lower expectations prior to moving into cohousing expressed a greater sense of well-being from living in Emerald Hills.

This bound project utilized research developed from an evaluation of the Humboldt Exchange Community Currency Project, a program administered by Democracy Unlimited of Humboldt County. I conducted this evaluation to complete the terms of the practicing placement contract, which I signed with DUHC and the HSU graduate coordinator. In this project I plan to treat my evaluation research as the basis for a case study. I use this case study to demonstrate connections between my evaluation of the Humboldt Exchange Community Currency Project and other Community Currency systems, to try and determine lessons that can be learned about sustainable development both in the local and global contexts. I utilize all the relevant literature on environmental and economic sustainable development, political economy, environmental sociology, as well as examine the theoretical discourse around the intersection between the grassroots development and parallel currency and economic theory. From this research I assess the Humboldt Exchange Community Currency Project, providing detailed suggestions for the future of the project including strategic outreach planning, administrative and structural changes as well as assessing the current condition of the program. My purpose in this study is to try and better understand how alternative systems of exchange can be integrated into development projects and to see first hand what some of the limitations are to this type of development.

In this study, I examined the effects of FMRFamide on the isolated crop-gizzard of the earthworm, Lumbricus terrestris. The peptide induced contractions of both the longitudinal and circular muscles of the crop-gizzard at concentrations examined (10-9 to 10-5 M). The responses were quantified by measuring increases in basal tonus, peak tension, integrated area, mean contraction amplitude, and contraction rate. FMRFamide application induced concentration-dependent decreases in basal tonus increase, peak tension, integrated area, and mean contraction amplitude of the longitudinal muscles. However, FMRFamide application induced a biphasic response in contraction rate where at low concentrations (10-9 to 10-7 M) there was an increase in contraction rate, but at high concentrations (10-6 ??? 10-5 M) the rate decreased and approached control values. FMRFamide application induced a complex multiphasic effect in basal tonus increase, peak tension, and integrated area of the circular muscles. At low concentrations (10-9 ??? 10-8 M) there was a decrease in each FMRFamide-induced response, whereas at higher concentrations (10-7 ??? 10-6 M) the FMRFamide-induced responses increased before falling at the highest exposure (10-5 M). Additionally, FMRFamide induced a concentration-dependent biphasic effect on mean contraction amplitude, whereas the contraction rate revealed an excitatory trend as FMRFamide concentrations increased.
The main aim of this study was to determine which signal transduction pathways were activated by FMRFamide in the crop-gizzard. It was discovered that the crop-gizzard lacks amiloride-sensitive sodium channels gated by FMRFamide. Second messenger pathway manipulation experiments suggested that the phosphatidylinositol and arachidonic acid pathways are involved in the FMRFamide-induced responses. FMRFamide-induced responses were reduced by the protein kinase C inhibitors, H-7 (5 ??10-5 M) and BIM I (10-5 M), calcium-calmodulin kinase II inhibitor, KN-62 (10-5 M), phospholipase A2 inhibitor, 4-BPB (10-6 M), and the phospholipase A2 and phospholipase C inhibitor, U-73122 (18 ?? 10-6 M). However, there was no evidence to suggest that the cAMP or NO-induced cGMP second messenger pathways were involved in the FMRFamide induced responses. FMRFamide-induced responses were unaffected by the protein kinase A inhibitor, H-89 (10-6 M), adenylyl cyclase inhibitor, MDL-12,330A (10-5 M), and guanylyl cyclase inhibitor, ODQ (10-6 M). Additionally, application of the cAMP analog, 8-Br-cAMP (10-5 M), NO donor, SNAP (10-5 M), and cGMP analog, 8-Br-cGMP (10-5 M) produced contractile responses that did not resemble those induced by FMRFamide. Certain drug treatments alone induced distinct contractile responses of the crop-gizzard, indicating the role of specific transduction mechanisms in mediating crop-gizzard spontaneous activity. Normal crop-gizzard spontaneous activity was altered by the calmodulin inhibitor, W-7 (10-4 M), and the tyrosine kinase inhibitor, genistein (5 ?? 10-5 M).

Two-minute television food demonstrations emphasizing quick, tasty, easy-to-prepare, economical foods were video taped bi-monthly and shown five times daily, seven days a week on a commercial television station. A survey was conducted with a voluntary convenience sample of European American adults who had viewed the demonstrations. It determined that 66% of viewers made some change in food purchasing and preparation as a result of viewing. The greatest change in knowledge and behavior was seen in participants 41-60 years of age. More than 80% of participants believed they were more willing to try new foods as a result of the demonstrations.

Christianity emerged from the desert periphery of the Roman Empire. The Roman Empire's growth necessitated centuries of imperial conquests, stratification, and extensive resource extraction. The result was widespread state oppression, social injustice, and environmental instability. Christianity responded to the Roman Empire's oppression and domination through political mobilization, social transformation, and ecological restoration. A knowledge that taught ecocentrism, communalism, and material simplicity is revealed in the oral and written tradition of first-century Christianity. To practice Christianity in accordance with the teaching of Jesus was to be inherently opposed to conquest and expansion. In resistance to the anthropocentric and consumerist lifestyle of the Roman Empire, the early Christian community sought to integrate balance into the interaction between the human and the other non-human forms of life.

The standards-based movement and the movement toward inclusion for students with learning disabilities have created a need for teachers to reform their teaching practices. Lesson Study, inspired from the Japanese Lesson Study model, is a professional development process that enables general education teachers to systematically examine their practice in order to become more effective teachers.
The lack of research exploring the inclusion of an education specialist collaboratively participating on Lesson Study teams forms the basis of this study.
First, a pilot study was conducted to test the language and substance of the research questions. The pilot study consisted of interviews and observations. Data from the pilot study determined the need for additional questions. Thus, follow up questions were drafted.
Following approval for additional research, four Lesson Study teams were contacted. A multi-case study was conducted using qualitative research methods. Three education specialists and three general education teachers were selected among the four Lesson Study cohorts located in three different counties in northern California.
Survey questions and subsequent follow up questions suggest a positive change in collegiality and teaching practice among general education teachers and education specialists, which may have a significant impact on current No Child Left Behind laws.
Not with standing, long term effects of this professional development model and its impact on colleagues and student learning within the individual school sites and districts have yet to be studied.

Intra-district transfers among elementary schools in "Longview School District" altered enrollment patterns among the schools. This study identifies the reasons parents chose to transfer their children beyond their neighborhood schools and offers recommendations for equitable access to choice.
Surveys were mailed to all families at three elementary schools. Questions probed parents??? use of school choice, reasons for transferring their children, and overall satisfaction. A qualitative examination of responses shows that many parents relied primarily on socioeconomic factors in making their choice; while lack of access to information and transportation influenced many non-choosing families.
Recommendations to equalize opportunity to participate in intra-district transfers include utilizing more effective ways to disseminate information, providing opportunities for transportation, and increasing the academic quality in neighborhood schools.

In 2004, the Eureka City Council legally returned forty acres of Indian Island to the Wiyot tribe. This return occurred one hundred and forty four years after the Indian Island massacre. This research explores the returning of sacred tribal land in the context of collective apologies and reconciliations after generations of Native genocide.
The significance of this case study includes a detailed narration of how the land transfer occurred and more importantly why it was labeled ???the right thing to do??? by Eureka City Council members and staff.
This case study was examined with a grounded theory methodology. Using no hypotheses, the research and the research methodology unfolded in a non-linear process, letting the research speak for itself. Detailed interviews and a review of documents were used to qualify and quantify this unique community based social act.
The results of this case study include how and why the Eureka City Council returned forty acres of Indian Island to the Wiyot people. The phrase ???the right thing to do??? was the frequent patterned statement made by Eureka City Council members and staff and is their explanation to why the land transfer happened. I have dissected this statement and have identified two main themes which include recognition and acknowledgment and historical features and importance. These two themes are then connected to the research on collective apologies and reconciliations.
My recommendations for continuing my unique case study are included as well as suggestions for more broad based collective apology and reconciliation processes. In conclusion, it is still my hope and desire that all of Indian Island will be returned to the Wiyot tribe as soon as possible. As my research shows, it is ???the right thing to do???, and I hope actions are made to facilitate that process sooner than later.

The literature reveals that teacher education programs are not adequately reducing bias and prejudice in relation to sexual orientation in preservice teachers. Many factors influence the lack of adequate preparation. Preservice teachers hold homophobic attitudes, exhibit unwillingness to address gay and lesbian issues, and show a general lack of knowledge about homosexuality. Preservice teachers indicate that their preservice programs failed to address issues of sexual orientation, exhibited more bias in relation to sexual orientation than to race and gender issues, and failed to prepare them to meet the needs of lesbian and gay students. Preservice teachers also show higher bias in relation to sexual orientation than race, gender, social class, ability and language/immigration.
Lesbian, gay, bisexual, transgender, and queer (LGBTQ) teachers have seen incremental advances in their struggle for equality in the schools. Teachers who identify as LGBTQ continue to hide their identity due to fear of loss of employment. Teachers attempt to pass as heterosexual and self-distance from sexuality as strategies to hide their identities. Queer teacher candidates express significant fears about teaching anti-homophobia content or coming out in their schools.
I interviewed nine secondary education credential candidates over the course of the year in the teacher preparation program. This study examines their responses to homophobia encountered in their schools. I focused on their understandings of the school climate, school policies, and support provided by the school to protect and support LGBTQ students. Candidates responded in proactive and reactive ways to homophobia and other forms of oppression. While some mentor teachers both supported and encouraged candidates??? efforts, others made homophobic comments themselves, or did little to model intervention.
This study also examines how queer identified teacher candidates understood LGBTQ issues in their schools and how they navigated their own safety and security in the homophobic environments in which they were teaching. They struggled in their attempts to address heterosexism and homophobia while simultaneously being victims of both.
This study asks the question: How does an intensive course in multicultural education affect teacher candidates??? practice and attitudes in relation to homophobia in a small northern California credential program?

This project began as an evaluation of the Expanding Your Horizons (EYH) 2003 conference at Humboldt Sate University. EYH in Science and Mathematics are conferences created to promote and foster interest for girls in the areas of science and mathematics. The conferences are held with hopes that girls who attend will be encouraged to consider careers in these disciplines. Research indicates that our past experiences and achievements, social backgrounds, school climate, and interactions with others help to shape our interests and self-image. These findings are consistent with EYH conference goals: Girls need activities that connect to their personal world and knowledge of non-traditional female career options, in order to increase their interest and confidence in math and science fields.
The positive responses on the evaluations conducted on the same day girls participated in the conference spawned a new interest in whether or not these one-day conferences had lasting effects on girls??? decisions around math and science classes. Therefore, a longitudinal study was designed to try to answer this important question.
The outcomes of the longitudinal project will impact girls in a rural, economically disadvantaged area with a high Native American population. The local AAUW branch will use longitudinal evaluation reports to determine how to best use its resources to encourage girls to pursue careers in the math and science. This project not only serves as a means for exploring girls??? decisions about math and science courses and careers, but also provides a blue-print for future studies on this subject.

This study was conducted to model the extent of eelgrass habitat in Humboldt Bay, California through physical surveys of the maximum depths and upper limits of growth in conjunction with recently acquired high-resolution bathymetry data and supplemental imagery. A combination of chronic turbidity, frequent coastal stratus, and wind-waves, make Humboldt Bay a challenging environment to assess subtidal eelgrass (Zostera marina) habitat from remotely-sensed imagery. Additionally, eelgrass and green algae overlap extensively in shallow intertidal areas, confounding efforts to distinguish between habitat types from imagery alone. A relative exposure index (REI) was developed to identify areas of eelgrass habitat that may be prone to disturbance from wind-waves. Approximately 2200 hectares of eelgrass habitat were identified. Accuracy was assessed at 91% for modeled eelgrass habitat in South Humboldt Bay based on a comparison with hyperspectral imagery captured in October, 2004. Modeling the extent of eelgrass habitat represents an important step towards understanding the extent to which future restoration or mitigation may be possible in Humboldt Bay.

This study examined changes in Sequoia sempervirens foliage along gradients of height and light availability. In tall trees (108-113 m), shoot morphology and physiology were analyzed at the base of the live crown, the mid-crown, and treetop. Both light and hydrostatic factors change along this within-tree gradient. To isolate the effect of hydrostatic factors related to height, morphological and physiological characteristics of foliage were quantified at the tops of trees ranging from 25 to 113 m tall. To isolate the effect of light, these characteristics were compared among treetop and non-treetop foliage from similar heights. Shoot mass:area ratio (SMA) increased with height and was less responsive to changes in light availability as height increased. Mass-based maximum photosynthetic rate (Amax,m) and mass-based internal CO2 conductance (gi,m) decreased with height while the light compensation point (LCP) and rate of dark mitochondrial respiration (Rm) increased along these gradients. In relation to SMA, Amax,m and gi,m decreased while Rm,a increased. Within tall trees, light and water potential both change drastically so that trends along the height gradient were generally pronounced. In contrast, among treetops from different height classes where light is relatively constant and only water potential changes with height, trends were generally less pronounced. Results suggest that at lower heights light is the primary determinant of morphology while at greater heights hydrostatic tension is the primary determinant. Increased respiration and decreased internal CO2 conductance associated with high tissue density likely reduce photosynthetic rates in the upper crowns of tall S. sempervirens trees. Further investigation of the relationships between internal CO2 conductance, aquaporins, and carbonic anhydrases is needed to determine if internal CO2 conductance is in fact limiting photosynthesis in tall trees.

Increased respiration and decreased internal CO2 conductance associated with high tissue density likely reduce photosynthetic rates in the upper crowns of tall S. sempervirens trees. Further investigation of the relationships between internal CO2 conductance, aquaporins, and carbonic anhydrases is needed to determine if internal CO2 conductance is in fact limiting photosynthesis in tall trees.

The identification of organisms present in an environment is a crucial prerequisite for understanding the role of organisms in the environment and the processes influencing the diversity of those organisms. In general, the basic ecology of acidic thermal environments is poorly understood, partially due to the lack of cultivability of prokaryotes from those environments. The purpose of this project was to examine the prokaryotic community composition in Boiling Springs Lake (BSL), a hot, acidic lake in Lassen Volcanic National Park (LVNP). Culture-independent methods were used to identify the prokaryotes living in BSL and to compare the prokaryotic community composition at four sites around the lake, ranging in temperature from 52.2-82.3??C. First, prokaryotes were identified using a 16S rRNA clone library constructed from water samples collected at the warmest of the four sites. Analysis of the clone library identified sequences from the domains Bacteria and Archaea. Approximately 75% of the clones sequenced and 27% of the identified phylotypes belonged to the domain Bacteria. Terminal Restriction Fragment Length Polymorphism (TRFLP), a molecular method that has been used to approximate diversity within microbial communities, was used to compare community composition at all four sampling sites. TRFLP diversity fingerprints were examined for intra-sample and inter-sample variation in an effort to evaluate the sensitivity and reproducibility of this method in detecting variation between and among
prokaryotic communities in BSL. Some variation between independent extractions of the same sample was observed, but, in most cases, it was less than the variation observed between different samples. TRFLP was able to resolve community composition differences between samples where differences were expected based on temperature. All
of the phylotypes identified in the clone library were detected by TRFLP in at least one of the sampling sites, and six of the phylotypes were detected in water samples from all four sites. Nonmetric multidimensional scaling ordination of TRFLP fingerprints generally resulted in clusters of extractions correlated with sampling site and temperature. TRFLP fingerprints from the warmest site were characterized by a Thermoplasmatales-like phylotype, an Ignicoccus-like phylotype, and Hydrogenobaculum. The results of this study provide an initial look at the bacterial diversity present in BSL and suggest that differences in community composition around the lake are correlated with temperature. They also indicate that TRFLP is a sensitive and repeatable enough method to detect variation in the prokaryotic community composition at various sites in BSL.

Seagrass beds are productive, structurally complex ecosystems that support an abundant and diverse assemblage of animals. Although light is clearly important to seagrass productivity, grazers also alter this aspect of plant communities. Grazers may indirectly affect the associated animal community but this perspective has not been rigorously examined in temperate western North American seagrass beds. My thesis objective was to experimentally examine the effects of Pacific black brant geese (Branta bernicla nigricans) grazing and fecal addition on the abundances and sizes of the animals within an eelgrass (Zostera marina) bed of Humboldt Bay, CA (40?? 43.1??? N, 124?? 13.3??? W). In situ brant simulations were used to investigate the effects of different treatments (clipping, fecal addition, the combination of both at ???intermediate??? and ???intense??? levels, and brant exclusion) on the abundances and sizes of the animals within the Z. marina community. Animal treatment responses were only compared when Z. marina vegetation structure (shoot density, shoot length) significantly differed among treatments. By including covariates like climate and water quality variables, as well as distance of a treatment from channels, this study also identified the recruitment and environmental conditions that favor the development of a positive or negative relationship between animal abundance and size versus Z. marina complexity. For example, large interannual variation in juvenile Dungeness crab (Cancer magister) abundance was attributed to warmer water current structure changes during 2005, and may have therefore delivered fewer megalopae to Humboldt Bay. Similarly, the effects of fish predation may have equalized the abundance and distribution of small Z. marina invertebrates, such as caprellid and gammarid amphipods and bay isopod (Idotea resecata), and thus prevented a relationship with vegetation structure from developing. Following the effects of climate on recruitment and fish predation, brant induced changes to the vegetation structure did affect animal abundances and sizes, but responses were species-specific. The abundance of Taylor???s sea hare (Phyllaplysia taylori) increased when a maximum number of shoots were created by intermediate levels of brant grazing, and both the abundance and size of P. taylori decreased in response to shorter shoots created by intense levels of brant grazing. Other animal responses responded negatively to brant induced changes to the vegetation structure. For example, I. resecata were smaller when shoots were more dense and longer, and they were larger when shoots were less dense and shorter. Lastly, the abundances and sizes of some animals were significantly different among brant simulation treatments, but animal differences did not parallel the brant induced changes to the vegetation. Therefore, brant induced changes to the structural complexity of Z. marina affect both the abundance and size of the associated animal community under a limited set of circumstances.

Three separate forest biomass harvesting systems were selected to study the operational performance and costs of systems designed to recover sawlog harvesting residues and silviculturally restore forests through stand conversion operations. These systems include the use of hook-lift trucks to access remote forest residues, energy wood harvesters to collect and improve density of residues through bundling, and integrated operations for the production of both sawlogs and energy wood chips. The overall system productivities were significantly affected by adverse road hauling distances, slash pile material size and arrangement, diesel fuel prices, and appropriate pairings of machinery. Slash pile arrangement and material size were found to have a significant effect on productivity of loading loose slash into trucks and in the bundling of slash. Forest biomass that was not accessible using traditional highway chip vans was successfully removed from previously harvested timber sites with hook-lift trucks. Energy wood harvesters were effective in collecting and compressing slash into bundles, and can be successfully incorporated into centralized grinding operations. Integrated harvesting of both sawlogs and biomass was a good method for silviculturally restoring stands and to produce both high value sawlogs and energy wood chips. Total system costs ranged from $32.98/bone dry ton (BDT) for residue recovery operations including a hook-lift truck to $46.50/BDT for bundling operations. All operations studied accomplished removal of forest residues for renewable energy production without the practice of open field burning.

This thesis constructs a mathematical model for the onset of water flooding of the cathode gas diffusion medium in a proton exchange membrane fuel cell. The model results include a coupled system of partial differential equations that govern diffusion driven mass transport. These equations are solved using finite difference approximations of the derivatives and the numeric solution is implemented with a Matlab algorithm. Using this algorithm, we obtain time estimates for the onset of flooding for a range of current densities and relative humidities. Taken together, these estimates form a time surface for the onset of flooding which characterizes proton exchange membrane fuel cell flooding behavior. Furthermore, this thesis demonstrates that the use of concentration dependent ternary diffusion coefficients generates a solution which requires fewer approximations of the governing laws, providing a more direct representation of proton exchange membrane fuel cell flooding dynamics.

This qualitative research study sought to evaluate the merger of two schools in terms of the staff members??? pre-merger and post-merger perceptions in an effort to identity best mechanisms in which two schools can successfully merge and create a positive climate among staff following a declining enrollment trend. Participants in the study were veteran staff members who had established collegial relationships and were comfortable with established procedures within their schools prior to the merger. Staff perspectives were obtained by utilizing an online survey that contained both Likert scale and open-ended follow-up questions. Additionally, several staff members participated in personal in-depth interviews. Results showed that teachers who were blended into the new school desired focused leadership, clear school procedures, and collegial time in order to create a common culture. Participant recommendations included bringing in an outside mediator to facilitate staff and department meetings along with providing sufficient time for groups to discuss curriculum and school policies prior to the first day of instruction as a mechanism for fostering unity.

Populations of flying squirrels occupying oak and oak-pine forests of the Mesoamerican highlands represent the least studied and most poorly known members of the genus Glaucomys. Traditionally, these Mesoamerican populations have been considered to be southern disjuncts of the southern flying squirrel, G. volans, a species that is also widespread across the deciduous and mixed-deciduous forests of eastern North America. The small number (less than 65) of Mesoamerican flying squirrel museum specimens in existence has made discerning the systematic and biogeographic relationships of these populations a challenge. In an effort to clarify the systematic position and biogeographic history of the Mesoamerican flying squirrels, we used ancient DNA techniques to extract, amplify, and sequence a 571-bp segment of the mtDNA cytochrome b gene from 34 of museum specimens. These represented five of six recognized subspecies of Mesoamerican flying squirrels. Mesoamerican flying squirrel data was combine with homologous sequences from representative populations of Glaucomys from across the rest of North America. This combine data set was phylogenetically analyzed using likelihood and Bayesians approaches. Results of phylogenetic analyses indicate that Mesoamerican flying squirrels form a sister monophyletic group to populations of G. volans from eastern North America. Within Mesoamerica, there are two distinct mtDNA lineages of flying squirrels: one comprising of populations from the Sierra Madre Oriental, Oaxacan highlands and Sierra Madre de Chiapas, and one comprising of populations from the Sierra Madre del Sur. These phylogenetic relationships suggest that divergence of Mesoamerican populations from those in eastern North America preceded a series of subsequent divergence events within Mesoamerica.

Mosquitofish (Gambusia affinis Baird and Girard) and threespine stickleback (Gasterosteus aculeatus) thrive in freshwater marsh habitats, in places where mosquito (Culicidae) larvae occur. This study assessed the potential impacts of mosquitofish (Gambusia affinis) and threespine stickleback (Gasterosteus aculeatus) on mosquito and other macroinvertebrate communities living in constructed wetland Hydrocotyle beds. Littoral macrofauna was collected at 48 sites within Allen, Gearheart, Hauser, and Aldergrove marshes in Arcata, California. Sites were sampled every two weeks from May through September of 2005 for fish and available prey by utilizing minnow traps and a 1 liter dipper. Stomach samples of juvenile and adult threespine stickleback and mosquitofish were compared with abundance and seasonal changes of potential prey to determine monthly diet preferences. Niche overlap value (Cxy (0.33)) demonstrated that little overlap was occurring in diet between both species. In addition, both species were utilizing potential prey items in proportion to their abundance. As mosquito larvae and other prey densities increased, both stickleback and mosquitofish diversified their prey selection to include a variety of prey. However, during this diversification in
prey selection, mosquitofish exhibited a Type III feeding response to mosquito larvae, while stickleback showed no clear response to the increase of mosquitoes. This difference in feeding response is likely due to concentration of predator search in the preferred habitat of the prey, palatability, prey vulnerability, and response to other prey items. The lack of predation on mosquito larvae, coupled with periodic consumption of mosquito larvae predators such as Dytiscidae, show stickleback would be inadequate as a biological control agent of mosquitoes in constructed wetlands. Mosquitofish significantly consumed mosquito larvae more than any other prey (p < 0.05), and consumed significantly greater numbers of mosquito larvae than stickleback when stomach samples from all marshes were examined. The positively correlated mosquitofish feeding response to increased numbers of mosquito larvae, especially in Allen Marsh, makes this fish a good choice for biological control of mosquitoes in heavily vegetated wetlands.

Through an examination of key texts and ideas concerning deep and transpersonal ecology; transpersonal psychology; psychedelics; and altered states of consciousness; this thesis explores the prospect for psychedelic use to serve as an effective tool in realizing a transpersonal ecology and developing a holistic relationship with the earth. Discussion of the theory???s implications will focus on the prospect for its acceptance and integration into the mainstream of American society considering its pluralistic nature. In this context, challenges to the theory???s viability will be presented along with ideas for how such challenges might be addressed.
Deep ecology is a philosophy that was first developed by philosopher Arne Naess in the late 20th century in resistance to the dominant anthropocentric worldview. Naess stressed the importance of humans achieving a symbiotic relationship with the earth; realizing the unified totality of nature; and asking deep, probing questions about what it means to be a human being living on the earth with non-human beings. Philosopher and ethicist Warwick Fox later refined Naess??? framework, deconstructing the essence of deep ecology, and concluding that Naess??? fundamental notion of deep ecology is best articulated as a transpersonal ecology wherein human beings achieve transpersonal identification with nature and thus form a holistic relationship with the earth. While Fox???s transpersonal ecology is a significant step forward in refining the logic underpinning Naess??? original philosophy, it still fails to answer one vital question: how or by what means might human beings achieve a transpersonal identification with nature and form a holistic relationship with the earth? Addressing this question is the primary concern of this thesis.

Every nine seconds a woman is battered by her male partner (Roberts and Roberts 2005:4). Many people ask, ???Why do they stay???? In reality many women leave. My thesis will explore this very process. This thesis is an exploratory, qualitative study of the process of women leaving
abusive relationships with a special interest in the various support, techniques, and experiences that aided them to flee. In addition, I have incorporated my journey in gaining access to my participants. I enrolled in a domestic violence training program where I documented my observations as a researcher attempting to gain access to the local domestic violence shelter. Finally, I interviewed seven women who left abusive partners. These interviews were one-on-one, semi-structured interviews. I utilized
grounded theory to analyze the data. I rigorously searched for common themes that turned into categories and recorded them accordingly.
Findings included identifying past barriers to leaving that included two types of fear; undifferentiated and differentiated fear, pressures of traditional gender socialization,
and economic dependency on their partner, all supported by the existing literature. The
women???s motivators for leaving included experiencing an escalation of abuse; others
reflected on the relationship and realized they needed to make a change. Finally, one woman experienced her partner demanding that she leave their home. All women experienced support from either formal or informal sources. The agents of assistance helped the women in the various ways; rediscovery, validation and emotional support,
some provided the women with securing their basic needs for them and their children. Some persons of support advocated for them with formal channels of assistance and some people and agencies employed distance between them and their partner. Throughout the violent relationships the women demonstrated resistance from either the violence they endured and/or their partner???s control. When the women left their partners they were able to rediscover themselves and look forward to new possibilities. While most of the
women felt empowered and experienced a new-found freedom, one was paralyzed by her situation.
While women experienced many sources of assistance, others ironically experienced a lack of help from organizations that were designed to help them. These ???ironies of help??? are explored. Finally, women had the opportunity to reach out to other women and share with them their insight on leaving abusive relationships.

Understanding the movements of anurans is important for developing successful conservation plans because breeding, foraging, and overwintering resources are often separated by time and space. I used radio-telemetry to study the movements and habitat use of the Foothill Yellow-legged Frog (Rana boylii), a stream-dwelling species experiencing significant population declines. Seventy-nine frogs (11 males and 68 females) inhabiting an inland watershed were opportunistically captured, fitted with radio-transmitters, and monitored during three two-month study periods. Females were tracked during one spring (2004) and two fall/winter seasons (2004 and 2005), while males were tracked during one spring season (2004). Site-specific weather conditions were monitored to evaluate associations with frog movement and habitat use. Movements and habitat use were highly variable among individuals during all study seasons. Frogs either centered activities at their initial capture locations or moved hundreds to thousands of meters among different stream habitats. The greatest distances traveled by male and female frogs were 0.65 km and 7.04 km, respectively. Frog size and age were independent of seasonal distances traveled. Mobile males and females moved 65.7 and 70.7 m/day (median), respectively, in spring and mobile females moved 37.1 m/day (median) in fall/winter. The maximum travel rate was 1386 m/day. Frogs used watercourses as movement corridors and rarely moved > 12 m from the stream channel. Spring movements were not associated with weather, but fall/winter movements were associated with increasing rain and humid conditions. Females showed an upstream directional bias during spring movements and a downstream bias for fall/winter movements. The results from this study highlight the need to manage R. boylii populations at the watershed scale to ensure protection of spatially separated resources commonly used by individuals throughout the year.

This case study illustrates the educational experience of five Latina English learners in California. Using a qualitative research approach, guided by the classroom ecology paradigm, I used an open-ended questionnaire conducting interpretative inquiry through a semi-structured interview format, which allows for
each participant???s unique story to be told. Each participant monitored how much or little they shared regarding their own experience in school. The results are presented as personal narratives for each case study participant, and ultimately, through the analysis, all experiences are woven together. Major areas of inquiry include

The Argentine ant, Linepithema humile, is a highly invasive insect affecting many areas of Mediterranean climate throughout the world. The Argentine ant has damaged biodiversity in invaded areas by disrupting seed dispersal and pollination, and endangering other animal species. This ant is also a household and agricultural nuisance, invading homes and living
mutualistically with agricultural pests.
Control of the Argentine ant has proven to be difficult because this species is polygynous. Being polygynous allows the Argentine ant to reproduce and spread rapidly. Entomologists are working diligently to understand this invasive species so that control efforts can be established. Much of the Argentine ant???s behavior appears to correlate with temperature. Thus,
we have constructed a temperature dependent system of ordinary differential equations
that simulates worker and brood numbers within a single colony. The second model adds
stochasticity to the temperature in order to look at the effects of temperature variance on the one year population levels produced by the model.

Thesis (M.S.)--Humboldt State University, Environmental Systems: Mathematical Modeling, 2008
The Argentine ant, Linepithema humile, is a highly invasive insect affecting many areas of Mediterranean climate throughout the world. The Argentine ant has damaged biodiversity in invaded areas by disrupting seed dispersal and pollination, and endangering other animal species. This ant is also a household and agricultural nuisance, invading homes and living
mutualistically with agricultural pests.
Control of the Argentine ant has proven to be difficult because this species is polygynous. Being polygynous allows the Argentine ant to reproduce and spread rapidly. Entomologists are working diligently to understand this invasive species so that control efforts can be established. Much of the Argentine ant???s behavior appears to correlate with temperature. Thus,
we have constructed a temperature dependent system of ordinary differential equations
that simulates worker and brood numbers within a single colony. The second model adds
stochasticity to the temperature in order to look at the effects of temperature variance on the one year population levels produced by the model.

In this explorative research project, data from questionnaires, interviews, and a focus group was collected and analyzed in order to explore aspects of the self-perception of professionalism in the field of early childhood education. Data was analyzed using three overarching themes that emerged in the literature: defining the profession, action and advocacy in the profession, and self-perceptions of early childhood educators. The data revealed that these three themes have significant inconsistencies that contribute to a state of disequilibrium and dissonance experienced among early childhood educators, creating obstacles to the move toward greater professionalism in the field of early childhood education.

This thesis is a qualitative exploration of ???new second generation??? South Asian Americans. Alejandro Portes and Min Zhou???s concept of the ???1.5 generation??? and ???new second generation??? illustrate a diverse and understudied demographic population that highlights the complexities of immigrant assimilation in the United States. The South Asian American population represents an understudied population that is often left out of the majority of literature pertaining to immigration, race/ethnicity, and general sociology. This research aims to provide a historical and contemporary exploration of the South Asian American community within the United States. In addition to the primary data, a historical discussion of ???three epochs??? of South Asian immigration is presented as a context in order to appreciate the lived experiences of contemporary 1.5 and 2nd generation South Asian Americans. Participants in this study were found using a snowball sample conducted in Southern California in the winter of 2008/2009. The participant interviews lasted from thirty minutes to two hours. The participant stories serve to illustrate and highlight many of the dynamics of assimilation, pan-ethnic identity formation and the effects of post 9/11 xenophobia and discrimination. Also discussed are a variety of concepts stemming from the two main themes that arose from the interviews. First, the concept of segmented assimilation is discussed with consideration of the impact of the participants??? and their parents??? social networks on their self-perceptions and identities. Secondly, the concept of pan-ethnicity is discussed, with consideration of how 1.5 and 2nd generation South Asian Americans??? views and opinions differ quite substantially from those of their immigrant parents. Finally, the participants??? views are discussed pertaining to discrimination and U.S. foreign policy in South Asia.

Special Education teachers are required to perform many different roles in a given day. It is well documented that students with disabilities often have social and emotional challenges which make it more difficult for them to learn. These challenges can come in many forms such as self-esteem, peer relations, home life, mental illness, social competency, and various other types of inter/intrapersonal difficulties, making teaching especially demanding for Special Education teachers. Effective social skills programs, whole school unifying approaches, mediation, and counseling type interventions have proven to aid in student success. However, in California it is not required for Special Education teachers to complete a counseling or mediation course. This study asks Special Education teachers through an online survey, with both qualitative and quantitative questions, what types of trainings they had, how often they were required to mediate non-academic issues, what those issues commonly were, what techniques they used, what supports they had, and if they felt that they were in need of further training. Specific challenges that teachers commonly faced and were required to deal with in order for students to learn are also explored. Special Education teachers have very diverse responsibilities that require them to be knowledgeable and skilled in many different areas. This study focuses on the supports necessary for teachers to learn how to effectively deal with students??? social and emotional challenges so they are able to learn.

Community supported agriculture, a form of food production in which the producer and consumer share in the risk and benefit of farming, is a social movement promoting an alternative to industrial agriculture. The origins of community supported agriculture are multifarious. The concept can be traced to several locations in the 1960???s including parts of Europe, Chile and Japan (Earles 2007; Henderson and Van En 1999). In the United States in the 1980???s, community supported agriculture (CSA) became the nomenclature for this community-based form of farming (Earles 2007). These agricultural developments shared a common theme: groups of people wanting a closer connection to the production of their food and producers wanting to build a connection with their consumers, working collectively to make it happen. CSA, while tailored to the demands of each location and community in which it is situated, is at the core a method for creating the connections between food, land, and community. My inquiry into this movement???s manifestation in Humboldt County led me to Redwood Roots Farm in Bayside, California. Here, my goal was to witness the creation and diffusion of CSA movement culture and information, known as knowledge-practices (Casas-Cortes 2000). The knowledge-practices underlying the local CSA movement, I discovered, had theoretical roots in the Marxist concept of class struggle as well as contemporary globalization theory. This experience led to the development of my project for the practicing track of the Sociology Master???s Program: a two-part curriculum for Redwood Roots Farm. The goal of this project is to empower community members to make socially and environmentally responsible decisions to influence a sustainable future for Humboldt County. The first curriculum, entitled ???A History of Agriculture in Humboldt County??? explores the development of local agricultural practices and organizations, focusing on the contemporary social forces that are shaping the agriculture of Humboldt. The next curriculum, ???Everything You Want to Know About Land Trusts??? describes land trusts as a tool for land preservation, highlighting local land trusts and their importance to the preservation of land for agricultural use and the CSA movement. In addition to facilitating the curriculum in workshops for the 2008 Community Workshop Series, I have made my work available for community access in the Redwood Roots Library.

No Child Left Behind has caused increased demands on all students, but in particular those students in the special education classroom. These students are required to learn more with less time and teacher interaction. Many students with learning disabilities require different approaches to instruction than their general education peers. In a world where teachers are asked to meet minimum requirements within given amounts of time, many special education students are falling through the cracks and are not given an adequate baseline of knowledge to help them build on basic skills for advanced learning. Many students are now faced with learning new materials without fully understanding the basic concepts that are addressed in earlier grades. Once students enter middle school it is assumed that they have knowledge of all basic math facts and skills that will help them understand and complete an Algebra course. Unfortunately, many of these students do not have route memorization of their math facts (defined as simple addition, subtraction, multiplication and division of single digit by single digit numbers). Many students continue to count on their fingers, state they do not know the answer or use a
calculator. Additionally, students are often not engaged in or find purpose when doing math facts individually and without teacher support. Studies have found that when students are given opportunities to verbalize responses their effectiveness and efficiency in memorizing new facts improves (Wolery et. al. 1992). This study will investigate the effect of a group of middle school students??? ability to improve their
math facts fluency by using a choral response method when completing a drill sheet.
It is hypothesized that the students who participate in the choral response method
will improve their fluency (and basic skill) knowledge as compared to a group of students who work on math facts with a repeated (silent and individual) method.

I examined differences in native macroinvertebrates among four lake management categories (fish stocked, temporary stocking suspension, fish removal lakes, and historically fishless lakes) and among three habitats (rock, organic/silt substrate, and emergent vegetation) from 16 different lake basins in a four-year study (2003-2006) in the Trinity Alps Wilderness in northeastern California. This study showed that introduced insectivorous fish reduce the diversity of native aquatic insects. Chironomid midges were more abundant and in greater proportion in fish lakes than in fishless lakes. Additionally, more taxa were sampled each subsequent year following fish removals and more taxa were sampled from Hidden Lake, a stocking suspension lake that did not maintain a fish population, than in the other three stocking suspension lakes that did sustain viable fish populations. The reduction in insect diversity due to fish was further exemplified in Hidden Lake alone, where more taxa were recorded each subsequent year of the study.
Libellula, a stout-bodied predaceous dragonfly, was most common in fish stocked lakes. The life history and morphology of Libellula (Odonata: Libellulidae) seems to give them an advantage over other invertebrate predators in fish lakes. Fish create top-down effects that are illustrated by the apparent ability of Libellula to regulate other insect abundances and proportions.
This study also demonstrated how large-bodied insects are more commonly found in complex habitats, which may be attributable to increased habitat availability and resources, to the invertebrates seeking refugia from insectivorous fish, or to a combination of both.

A point or percentage based system of grading that is reported in standard letter scores has traditionally been used by most middle and high school teachers to report student achievement to students, their families, and administration. Despite large variation in point gathering policies between each teacher and volumes of research to discourage it, little has been done to develop a system of feedback that improves student learning. This thesis addresses a rural middle school???s attempt to rethink assessment, feedback, and grading to improve student learning.
It explores the process one rural middle school employed to implement a criterion referenced grading system based on state standards. The focus of the research is to understand what initiated the change; what process the school community went through in developing a unique system of feedback; and what impact these changes had on assessment, feedback, motivation, and teaching. As the use of this grading system is new, this research also attempts to qualify successes and failures of the system and make recommendations for improvement and growth.
This thesis presents a qualitative case study of how a small rural middle school staff researched, designed, and implemented a criterion referenced grading system based on state standards. This is an historical organizational case study that utilizes interviews with teachers at the school and artifact analysis.

At the time of European contact, the southern California mainland coast and Channel Islands were occupied by a variety of Native groups that were socially complex and steeped in rich cultural traditions. Archaeological evidence found on San Nicolas Island, the most geographically isolated of the Channel Islands, offers a unique opportunity to examine past human daily practices and underlying social organization and world-views. This thesis focuses on the archaeological record at CA-SN-25, a village occupied intensely between approximately A.D. 1300 and A.D. 1800. Analysis of shell and exotic stone artifacts indicates a variety of domestic and ceremonial activities occurred at the site. Comparisons of CA-SNI-25 to other sites on San Nicolas and the Channel Islands suggest the villagers were intricately connected to other groups through family ties, exchange interactions, and socio-ritualistic activities. In all, this thesis illustrates the importance of archaeological investigations as a tool to enhance our understanding of daily practices, social and spiritual organization, and regional interactions of the Native people of San Nicolas Island.

Gray whales (Eschrichtius robustus) are ???living islands??? to a diverse assemblage of crustacean ectoparasites that includes at least three species of highly specialized whale lice (Cyamus spp.). These lice are obligate parasites that undergo direct development on the gray-whale host, and are dependent on direct physical contact to colonize a new host whale. Given their high degree of morphological specialization and obligate relationship with whales, whale lice might be expected to have a close, long-term evolutionary association with gray whales. Such a relationship can lead to an evolutionary history of the parasite that closely mirrors that of its host and a highly correlated demographic history between the host and its parasites. Here I use a 738 base pair fragment of the mitochondrial DNA (mtDNA) cytochrome c oxidase subunit I gene (COI) gene to: (i) examine the phylogenetic relationships among, and genetic diversity within, gray-whale lice (C. scammoni, C. kessleri, and C. ceti); and (ii) to infer historical demographic patterns within each species of whale louse. Whale lice samples were collected from five different gray-whale hosts. Gray-whale lice exhibited relatively high levels of genetic diversity suggesting large effective population sizes and gene flow among different gray-whale hosts. Each species of louse was phylogenetically distinct and reciprocally monophyletic, indicating congruence between morphological and mtDNA phylogenies. The phylogeny also suggests that collectively these whale lice do not form a monophyletic group, supporting the hypothesis of independent, historical colonizations onto the gray-whale host. All louse species exhibited relatively high levels of genetic diversity. Mismatch distributions for all three gray-whale lice are consistent with long-term, stable historical population sizes and all three lineages coalesce to approximately 800,000 years before present. The polyphyletic relationships of gray-whale lice provide three independent replicates for indirectly examining the demographic history of their host, the gray whale.

Phytoremediation has become one possible remediation strategy to address lead toxicity. The heavy-metal tolerance of Typha latifolia (broadleaf cattail) has made it a potential candidate for chemically enhanced lead phytoremediation.

The use of field data: cross-sectional profiles of the stream channels, temperature, average daily flow, etc. is used to define the virtual habitat for the fish. The study is separated into two parts: 1) Teton River connected to Fox Creek and 2) Teton River connected to Teton Creek. The results of studying how peak and minimum flow affects fish populations are displayed. Reasons for shifts in species dominance are presented.

Terrestrial and atmospheric chemistry is affected by allocation patterns in plants. Experimental results show that environmental factors including water, nitrogen, light and atmospheric CO2 affect plant biomass productivity and allocation. Various global vegetation models describe the cycling of carbon and water between land and atmosphere using terrestrial processes and biomass allocation schemes. The latter still have great margins for improvement in terms of dynamic responses to atmospheric CO2. Based on new results from experiments involving plants growing at double atmospheric CO concentrations, a dynamic allocation scheme is applied to the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM) with the objective of reproducing the observed ecosystem productivities and structural changes in a elevated CO2 environment. The allocation scheme is based on the definition of apparent environmental resources for which levels are determined by linear perturbation of actual resources induced by elevated CO2.

Marine snow aggregates are important components in the ocean carbon cycle because their sinking transports carbon from the surface layer of the ocean to the deep ocean where carbon can be sequestered for hundreds to thousands of years. The sedimentation rate of marine snow out of the mixed layer can be influenced by swimming euphausiids, Euphausia pacifica, because euphausiids are able to fragment a single aggregate into multiple smaller particles and potentially reduce carbon flux out of the ocean surface layer also known as the mixed layer. The interaction between rapidly sinking large particles and animal behavior has been recently discovered and there are not many studies on this process. We used a system of ordinary differential equations to develop a mathematical model that examines the change in the concentration and the total volume of aggregates with and without fragmentation by euphausiids and investigated how these changes influence marine snow sedimentation. Our results shows that through swimming behavior alone euphausiids are able to reduce carbon transport out of the ocean surface layer by approximately 30%. Fragmentation by euphausiids is an important process affecting marine snow sedimentation and the transport of carbon out of the mixed layer, and thus it has an impact on the global carbon cycle.

It is the intent of this study to simulate the invasion of Cortaderia jubata, jubata
grass, into a disturbed second growth redwood forest where the dynamics of the grass and
its relationship to the environment are explored through a spatially explicit individual based landscape model. The field of neighborhood approach is used to simulate both the evolution of the forest and the grass. What is of particular interest is the success of the invader in terms of spatial distribution and time with regard to varying disturbance regimes. To assess these qualities, seed dispersal and the field of neighborhood each plant exerts are used to parameterize the model and a measurable plant attribute, self thinning, not included in the model assumptions, is used to test the model's validity.

It is the intent of this study to simulate the invasion of Cortaderia jubata, jubata
grass, into a disturbed second growth redwood forest where the dynamics of the grass and
its relationship to the environment are explored through a spatially explicit individual based landscape model. The field of neighborhood approach is used to simulate both the evolution of the forest and the grass. What is of particular interest is the success of the invader in terms of spatial distribution and time with regard to varying disturbance regimes. To assess these qualities, seed dispersal and the field of neighborhood each plant exerts are used to parameterize the model and a measurable plant attribute, self thinning, not included in the model assumptions, is used to test the model's validity.

Our sediment transport model is developed using the hydrologic cycle as representative of the routing of water through a watershed. The elements of the hydrologic cycle described are rainfall, interception of rainfall, evaporation, infiltration, surface flow, groundwater flow, and stream flow. Surface flow is used as the transport mechanism for sediment. These elements of the hydrologic cycle are incorporated in a digital elevation model to predict the effects of forest stand age on the processes of erosion and sediment transport. A multiple regression model is used to generate soil depths throughout a watershed based on slope and elevation. A combination of continuous and discrete models is used to evaluate areas shielded from erosion by the forest canopy based on stand age. The production of large woody debris is modeled using an augmented Leslie matrix. A Markov chain predicts the production of organic debris and the volume contributed to sediment transport. The entire model is applicable in areas such as the small, steep watersheds of Northern California. It is capable of generating stand age distributions and occupancy areas for managed lands, as well as successional and old growth forests. The model can be used for evaluating habitat based on unit hydrographs, erosion, and sediment transport.

A spatial model for the consumption of organic forest soil (duff) by
smoldering combustion is developed. Smoldering ground fires have an enormous
impact upon the ecology and management practice of forest lands throughout the
temperate zone. It is the goal of this
effort to predict, and hence better understand, observed spatial patterns in
duff consumption. Models of duff consumption are often empirically derived and
consequently too specific to the site of study. Additionally, models of duff
consumption based upon models of smoldering combustion are difficult to use and
can yield questionable results since few, if any, models of smoldering
combustion are created specifically for duff. This effort seeks to circumvent
such shortcomings by creating a general duff consumption model that requires a
small number of user-determined parameters that are easily estimated from field
samples. These parameters include organic bulk density, moisture content,
mineral content, and duff depth. The fuel-bed is modeled by a two-dimensional
stochastically updated cellular automaton. Model output compares favorably to
empirical and field studies concerning spatial aspects of duff
consumption. Modifications to the model are proposed that would advance
understanding of the ecological impact of duff consumption.

Analyzing DNA sequence data from multiple unlinked loci in a coalescent framework is a powerful means for assessing the genetic isolation of populations by estimating population divergence times and gene flow since divergence. This approach was used to study three ecologically and morphological distinguishable populations of the Black Salamander (Aneides flavipunctatus) that are parapatrically distributed in northwestern California. These populations meet at a three way contact zone in northern Mendocino County, where abrupt transitions in color pattern, vertebral number, and microhabitat preference are observed. Analysis of seven presumably independently assorting loci reveals that the northern population diverged simultaneously from both southern populations 2.6 MYA. There has been little gene flow out of the northern population into both southern populations, though there is some gene flow into the northern population. The coastal and inland populations diverged from each other 1.9 MYA, and there apparently has been substantial gene flow between. The effective population sizes were estimated for the coastal and inland populations at 1.1 and 1.4 million individuals respectively, and the ancestral effective population sizes were all estimated at around 900,000 individuals. Based on the divergence times and relative genetic isolation of the southern populations from the northern population, these findings suggest that the main portion of the range contains a northern and southern species.

The valley elderberry longhorn beetle (VELB) lives in elderberry bushes in the Central
Valley of California. It is threatened under the Endangered Species Act and is also of
theoretical interest because it persists at low densities in a patchy landscape. It is thought
to exhibit many of the characteristics of a classical metapopulation. The life cycle of VELB
consists of eggs, larvae and adults. Beetles are eggs for a few days, larvae for one or two
years, and adults for a few weeks. The larvae live inside and eat the pith of elderberry
stems (Talley, 2005). Since, VELB exist in small local populations, we propose stochastic
migration and reproduction could be important to the long term persistence of the VELB.
We study how habitat configuration, dispersal range and density dependence may effect the
persistence of the VELB. We develop a stochastic two age structured model; the Adults can
migrate, and the Juveniles cannot. There is density dependence on the eggs and early larval
stage. In our model, beetles tend to stay on the bush they were born on. We run simulations
to study the effects of differing types of density dependence, differing variations of our
migration rule, and different habitat configurations. We found that having a lot of patches allows beetles to persist in a landscape over many years. We also found that not all bushes
must be occupied for the the population to persist. The implications of our results for
conservation are consistent with existing management plans.

Jimmy Carter seemed to be the appropriate presidential candidate in the election of 1976 due to his personal characteristics of honesty, devotion to others and his incredible work ethic. He provided a type of possible salvation from the dual fiascos of Watergate and Vietnam, which had caused many Americans to simply write the political system off as corrupt, especially the presidential office. The political climate post Watergate is important to understand as well as the type of man Americans were willing to elect in 1976. Many scholars have looked to the Moral Jimmy (Morris Jimmy Carter: American Moralist) as just that type of man and yet that same trait may have made getting anything done a more difficult task in Washington.
From his childhood and through his Naval career, Mr. Carter personified the small town boy. Growing up in a small Southern peanut farm, the Carters were never a rich family. Often waking early in the morning to help his father with chores, a sense of hard work was ingrained at an early age. Religion played a key role in his upbringing, as did the role of family, especially his mother. Incensed by the inequities he found in his post WWII hometown he entered politics. From a Georgia Senate seat to the governor???s mansion, Carter worked hard, promised not to lie, and to be thrifty with the people???s money. (Carter, Why Not the Best, Bourne, Jimmy Carter and Hyatt, The Carters of Plains)
The Election of 1976 was in many ways a new type of election, altered by legislation hoping to curb the powers of an imperialistic president and yet it was also dominated not by the issues that had dominated early elections, for example civil rights and the policies in Vietnam. (Schram, Running for President 1976: The Carter Campaign, Bitzer and Rueter, Carter v Ford: The Counterfeit Debates of 1976) Instead, it was a contest between two men promising healing and a new outsider perspective. In many ways, American voters said that they wanted a man of integrity first and then worry about the issues the nation was facing because without trust all else was a mute point. (see Appendix M: Carter???s Acceptance Speech at the Democratic Convention)
Everything about his childhood and political career seemed to say that Carter was sincere in his goals, yet as crisis after crisis arose during his presidency he found it increasingly difficult to balance his personal feelings of morality with the political massaging necessary to get things done in Washington. From the Middle East to the economy, the Iranian hostage situation and the environment, Carter was always trying to do the ???right thing.??? The hard work turned out to be overworked and the honesty was sometimes too honest for many American to swallow. (See Carter???s ???Crisis of Confidence??? Speech) Of course, Carter???s presidency has been viewed as ineffective and filled with contradictions (Mollenhoff, The President Who Failed: Carter Out of Control and Kaufman, The Presidency of James Earl Carter Jr.) In many ways the characteristics that made Carter a viable and popular candidate also hampered his ability to participate in the political process. Carter struggled with his desire to do the right thing in a world where that was not always possible.
However once free from the constraints of the Oval Office, Congress and the constant scrutiny of the press, a Carter enveloped by his passions is revealed. (Brinkley, The Unfinished Presidency) Carter???s human rights efforts around the world have been recognized, including a Noble Prize.

The Cuban Missile Crisis is thought by many to have been the most dangerous moment in the Cold War and perhaps, in human history. Historians??? ???understanding??? of this event has undergone dramatic evolution. Continued study of this event remains valid as long as international conflict remains a reality; historians, political scientists, and policymakers investigate this event in an attempt to understand and alleviate future foreign policy and conflict. Recently declassified documents and recordings and the end of the Cold War between the Soviet Union and the United States have made more information available regarding the nature of the crisis, its creation, and resolution. It is evident, however, that a greater volume of information pertaining to the crisis has not led to consensus, or a greater understanding of the causes and consequences of the event. Most historians do agree that Nikita Khrushchev, Fidel Castro, and John Kennedy each played a pivotal role in the crisis and its resolution.
This project draws on a variety of sources regarding the crisis and its administrators in an attempt to create an historiography of the available information regarding this important event. It begins with a discussion about the available information on the Cuban Missile Crisis and a history of the pre-crisis Cuban-American relationship. I have investigated this crisis from the perspective that the character, actions and policies of Khrushchev, Castro, and Kennedy were inexorable in instigating and resolving the crisis. I hope that this project will provide educators and students of history with a greater understanding of the opposing views regarding the motivations and actions that resulted in the Cuban Missile Crisis and its outcome

An individual-based model has been developed to simulate the evolution of traditional foraging strategies in a fluctuating environment.

An individual-based model has been developed to simulate the evolution of traditional foraging strategies in a fluctuating environment. The parameters and procedures are based on observed behavior of Barnacle geese, Branta leucopsis, during spring staging off the coast of Helgeland, Norway. Within a spatially heterogeneous environment, goose movement is modeled according to state dependent site selection decisions which maximize food intake. The aim of each individual is to optimize fitness (survival and reproduction) by gaining enough food (energy reserves) during three weeks of foraging to meet a threshold of energy necessary for successful reproduction. The geese return to the same islands each year, and on a daily basis choose unoccupied sites according to their rank in the population structured dominance hierarchy, memories of previously visited sites (tradition), past reproductive success, inherited genetic influence towards site faithfulness and/or site quality, and knowledge of the available biomass density. It is assumed that with each subsequent return to a specific location, increased familiarity of the area will benefit an individual through greater food acquisition by more efficient foraging practices. In the event of variable environmental conditions, geese are faced with a critical decision to return to previously visited sites or abandon tradition to explore for something better. It is shown that habitat quality plays an integral role in population dynamics. The evolution of foraging strategies which directly affects reproductive potential will inevitably determine the resilience of the population over time.

Long term comparisons are important for understanding intertidal community dynamics and documenting response to environmental pressures. This study compares the historical abundance of high intertidal sessile organisms at two rocky intertidal sites within Redwood National and State Parks shortly after the park was established (???historical???:1974-1976) to the present community (2004-2005) at the same locations. Percent cover of ephemeral, early successional species was higher in historical assessments, whereas percent cover and magnitude of seasonal variation in perennial, late successional organisms increased in assessments of the present community. The long term successional shift is likely a result of decreased disturbance severity between the mid 1970???s to present. Severe historical disturbance is linked to increased sedimentation and frequent driftwood battering associated with logging. Conservation and rehabilitation strategies in the adjacent terrestrial landscape since 1978 may have resulted in spatial dominance by mid to late successional species at these two sites. Several alternative causal hypotheses regarding long term climate change, El Ni??o Southern Oscillation, upwelling intensity, and species interactions are evaluated, but not supported by the results of this study.

The purpose of this study was to examine the relationship between length of sobriety in members of Alcoholics Anonymous and involvement in the program of AA, religious faith, purpose in life, and social support for both males and females. Level of involvement in Alcoholics Anonymous was measured using the Alcoholics Anonymous Involvement Scale (Tonigan et al., 1996). Religious faith was measured using the Santa Clara Strength of Religious Faith Questionnaire (Plante & Boccaccini, 1997). Purpose in life was measured by the Purpose in Life test (Crumbaugh & Maholick, 1964). Social Support was measured with the Social Support Appraisals Scale (Vaux et al., 1986).
Surveys were completed by 150 members of Alcoholics Anonymous in both Humboldt and San Francisco Counties. The findings of this study suggest that involvement in the program of AA is the strongest predictor of length of sobriety for the total sample. Significant differences were found when males and females were examined separately in terms of what variables were most strongly related to years sober. Social support had the strongest correlation of any of the variables tested with years sober for men, while AA involvement was the only variable that was significantly related to length of sobriety for women in this study.

Increased sophistication in methodology of echolocation monitoring has enabled the pursuit of a widened array of research and management objectives for bats. I developed and tested an automated program for detecting, measuring and classifying species of bat echolocation calls. I analyzed 584 echolocation sequences from nine bat species of the eastern United States (Lasiurus borealis, Myotis austroriparius, M. grisescens, M. leibii, M. lucifugus, M. septentrionalis, M. sodalis, Nycticieus humeralis, and Pipistrellus subflavus). A base set of 11 variables was measured automatically and manually, and an additional 28 variables were measured automatically as a part of the full variable set. Species were classified using Discriminant Function Analysis (DFA) using each variable set and measurement method with both a single DFA and a hierarchical set of DFAs that classified genus level before species level. Classification rates were also summarized for a subset of the sequences with Discriminant probabilities > 0.75. Overall classification rates were 67.6% for manually measured base variable set, 63.0% and 68.3% for automatically measured base and full variable sets, respectively, and 84.4% for the 62.5% of calls with Discriminant probabilities > 0.75 using the automatically measured full variable set. Hierarchical classification improved overall classification rates by < 2% for base variable set classifications and 6.8% and 6.9% for the automatically-measured full variable set with and without the Discriminant probability cutoff, respectively. Hierarchical classification worked synergistically with a large variable set to increase classification rates. Six of nine species had overall classifications of 93.3-100% with the best classifier. Also, six of nine species had higher classification rates than that achieved in previous studies. Automated call processing is a fully objective and repeatable method requiring less cost, time, and user expertise than manual methods, especially for large datasets. Further sophistication will likely continue to offer improvements to echolocation monitoring methodology.

This project is a program evaluation of the Maine Downtown Center. The Maine Downtown Center (MDC), a program of the Maine Development Foundation, a 501 (c)(3), offers services on two levels. MDC serves as a resource to all downtowns in the
state of Maine that have the desire to revitalize their downtowns and it provides assistance to designated Main Street Maine communities. Main Street Maine communities are selected by MDC through a competitive process based on specific
criteria. The Maine Downtown Center (MDC) was fairly new at the time of this project and had not been previously assessed. The executive director of MDC expressed perceived tensions between key stakeholders. The intent of the MDC program evaluation was to discover perceptions of key stakeholders of MDC: Advisory Board Members and Main Street Maine Downtown Managers, interpreted as indicators of program effectiveness. Because non-profits have transitioned in the last few decades through adoption of more business-like practices, there has been an increased interest in determining criteria for non-profit effectiveness. Two of the most emergent theories in determining stakeholder perceptions of non-profit organizational effectiveness are the multiple
constituency and social constructionist models.
There were four prevalent themes that arose out of the qualitative interviews of the board members and downtown mangers. Tensions of key stakeholders were based on perceptions that the executive director was not responsive to their needs, consistent in services provided, did not create formal or informal mechanisms for open dialogue, and did not perform needs assessments.
Using the perspectives of the multiple constituency and social constructionist models, recommendations were made based on shaping stakeholder perceptions through management strategies that include responsiveness, consistency, open dialogue, and needs assessments. Because the literature on determining non-profit organizational effectiveness is limited in general, and considering stakeholder perceptions as criteria for effectiveness even more limited, there is a need for longitudinal studies of organizations that use management strategies to shape stakeholder perceptions to determine if these strategies influence perceptions and/or actual organizational effectiveness.

Invasive, or exotic, plant species are commonly found lining roadsides and tend to favor disturbed areas that have been cleared of vegetation. Construction and maintenance of roads, utility corridors, trails, railways, etc. create disturbances and thus contribute to the establishment of exotic species. Despite the influence of disturbances on invasions, invasion models have yet to fully address the spread of interacting, competing species through heterogeneous landscapes. By considering space as two discrete patches and alternatively, by considering space as a continuous line we model exotic and native populations of plants interacting and dispersing adjacent to a theoretical roadside. A small fraction of the spatial domain in each consideration is treated as road margin where we assume the exotics out-compete the natives; the remainder of the domain is considered interior where the exotic could not invade without the road margin. Initially we assume the road margin is free of any species and the interior has an established native community at carrying capacity. Numerical conditions for which a small amount of exotics released in the road margin can successfully invade the interior are established for both spatial considerations, and the results are qualitatively similar. Bifurcation diagrams for the stability of the equilibrium point at native carrying capacity are generated for the discrete space model. Parameter regions for the exotic competition coefficients indicate that the exotics successfully invading the interior depends on the values of the competition coefficients throughout the region. Results confirm the threat posed to native habitats by exotic plant populations spreading along road networks, underscoring the need for eradication of invasive populations early on in their establishment in disturbed areas adjacent to native populations.

This project examines the experiences of children with autism and their families including diagnosis and treatment. Parents, especially those in small rural communities, may find it difficult to access and assess services that are available to them to provide support to their children with autism and to the family as a whole. The content of chapter four is a handbook designed to assist parents and guardians in Humboldt and Del Norte Counties in seeking appropriate services for their children with autism. Content includes information on grief, specialized services, schools, and behavioral techniques that will assist parents in developing a team to support their children with autism and their families.

This project examines the experiences of children with autism and their families including diagnosis and treatment. Parents, especially those in small rural communities, may find it difficult to access and assess services that are available to them to provide support to their children with autism and to the family as a whole. The content of chapter four is a handbook designed to assist parents and guardians in Humboldt and Del Norte Counties in seeking appropriate services for their children with autism. Content includes information on grief, specialized services, schools, and behavioral techniques that will assist parents in developing a team to support their children with autism and their families.

Over the past several years, ecologists have begun to recognize that the role played by positive plant-plant interactions, specifically facilitation, in communities is under appreciated. Despite this recognition, little is known about how these positive interactions influence population and community dynamics. One theory posited by Bertness and Callaway in 1994, suggests that the relative importance of the effect of facilitation on plant distribution and abundance may depend on the level of abiotic stress. At high levels of stress, plants may create hospitable environments for neighboring plants (or sessile organisms), despite competition for limiting resources. In this experiment, I conducted a neighbor removal experiment in a dune ecosystem to test the relative importance of competitive and facilitative interactions at varying levels of abiotic stress. Stress levels were manipulated using PVC lattice shelters to decrease the effect of wind and associated stress. The effect of neighbor removal on the survival, aboveground biomass, stem length, leaf number, and reproduction of the target species was tested between high stress and low stress plants in treatments with and without neighbors, and in two habitat types. The strength and direction of the significant disordinal interactions between the variables indicated that plants sheltered from wind did better than plants exposed to wind, and in general, that this trend was not as apparent when neighbors were left intact. There was also evidence of interactions between shelter and neighbor treatments, indicating that the positive response of sheltering depended on the presence or absence of plant neighbors. Relative competition intensity values showed that positive interactions were more common in high stress sites. These outcomes are clearly consistent with the theory introduced by Bertness and Callaway that facilitation is more common at high levels of abiotic stress.

Handwriting/fine motor difficulties are well documented as serious hindrances to academic learning for kindergarten and elementary school children. Intervention techniques to remediate these problems have been researched by educators and occupational therapists. Effective occupational therapy interventions have been found to include visual motor tasks, kinesthetic and dexterity training and motor planning/strengthening activities. Occupational therapists, mandated by the Individuals with Disabilities Education Act, work with these students in the school setting to enhance handwriting/fine motor skills to meet classroom curriculum demands. Humboldt County teachers have reported a high incidence of students with these deficits in their classrooms yet reported a low frequency of referral to occupational therapists for intervention. Funding and a lack of general knowledge about the role of therapists??? in the school setting appear to be barriers to implementation of therapy services for students. These same teachers indicated a strong interest in continuing education on remediation techniques. An educational module designed for staff development for teachers in Humboldt County on handwriting/fine motor intervention strategies appears to be needed. Curriculum for students is rigorous with many academic topics to cover. Imbedding fine motor remediation techniques into another discipline seems advantageous. Food related activities naturally lend themselves to fine motor involvement. Staff training encouraging vegetable awareness and handwriting skill acquisition is an effective way to impact student learning in two specialty areas. Linking fine motor intervention with nutrition education will be a cost effective, compelling, and creative solution to meet teacher and ultimately student needs in Humboldt County.
