- Description:
- This master’s project investigates the feasibility of establishing a composting facility for greenwaste diversion on Vashon Island, WA. The composting facility would serve to compliment waste reduction efforts already in place on the island. The benefits from this project would include reducing greenhouse gas emissions, costs savings and creating a local product. I conducted a survey of the public schools and local restaurants to determine potential feedstock for the composting facility. In addition to the survey, results from a statewide waste characterization study were used as a guide for estimating the potential greenwaste available from residential households. The analysis indicates that approximately 3,100 tons of greenwaste are potentially available for diversion annually, largely from residential and landscaping debris sources. The survey results suggest that there is little interest in participating in a composting project by schools and restaurants, but that these organizations do not generate significant quantities of divertable greenwaste. Overall $25,620 could be saved in annual ferry and fuel expenses if 100% of the food waste and green debris currently going to the landfill were diverted to an on island composting facility. This number is likely to increase in time as nearby landfill options decrease and waste hauling costs increase. Currently, King County is reviewing the results from their island wide survey administered last spring to island residents regarding interest in a residential curbside pickup program for greenwaste. Once the results have been considered, King County will offer a public comment event on Vashon to hear directly from the citizenry. The analysis in this master’s project will inform the decision making process; it suggests that greenwaste diversion may be feasible provided that residential greenwaste diversion rates are sufficiently high and the facility can be constructed at the existing transfer station at a reasonable cost.

- Description:
- Annie Smith Peck, a scholar, explorer and Pan-Americanist, educated the general public and businessmen about geography, especially Latin American geography. Peck wrote and lectured to Americans about tourist sights, archeology, exploration, mountaineering, and Latin America- including travel, industry, and trade. Peck also educated Latin Americans about the United States. This was significant because, as is the case today, the American public was geographically illiterate. The Pan-American movement, the idea of peace between North and South America, was in full force at the time, and thus Peck was one of the movers and shakers in the movement. Peck believed education was the most important means of freedom for the impoverished- in both North and South America. Methodologies include: letters to the editor by Peck, newspaper articles about her, and correspondence between her and other explorers and diplomats. I also read Pecks writings, including her four books and many of her newspaper and magazine articles. I reviewed numerous articles and books about South American politics and diplomacy in the early 1900s. Historical organizations, corporations, colleges, and other groups she had contact with, such as the Wisconsin State Historical Society, and Smith College, provided materials about Peck. Information about other explorers of her time, Pecks friends, and diplomatic acquaintances also yielded much primary biographical knowledge. I conclude that Peck contributed to the geographic education of North and South Americans as a mover and shaker in the Pan-American movement. In doing so, she attempted to promote peace and understanding between the Americas.

- Description:
- This study explores the prevalence and the relationship of cyberbullying among Native American students at Humboldt State University. Cyberbullying defined in brief is the repetitive use of technology to harm an individual. Cyberbullying is a widely studied issue that has gained International media attention with the tragic deaths of several youths and students resulting from having been cyberbullied. A host of debatable issues have emerged from the International research involving cyberbullying including age-specificity of the term, applicability, overlapping, and competing legislation of non-cyber crimes with the expanding cyber-issues, problems associated with varied instruments and inconsistent operationalization and measurement of constructs, and as school budgets are increasingly restricted debate about how best to use funds in the crafting of bullying prevention policies for schools. Trends in cyberbullying research also emerging from the literature include age, gender, ethnicity and cultural effects on prevalence rates, types of forums and technologies used, and the affect and motivations of victims and perpetrators. The present study used a modified version of an 81 item instrument but whose current convenience sample included 272 University students, with an overrepresentation of Native American students (n=58) at 21% of the sample representing 23 US Federally recognized tribes, anonymously surveyed in the Spring and Fall of the 2013-2014 academic year. The exploratory study produced robust data including demographic distinctions for comparison of gender, ethnicity, and adherence to tribal traditions for Native American respondents. Also reported on are, the identity of the perpetrator -addressing the role of anonymity, the frequency of daily Internet and cell phone use, for cyberbullying victimization and perpetration the frequency of occurrence and type of forums used and the resulting affect of victimization and motivation of perpetration. The major research question centered on the potential effect adherence to tribal traditions had for Native American respondents on the rates of perpetration and victimization. Major results include significantly higher rates of cyberbullying victimization and perpetration for Native American respondents that adhered to their tribal traditions and values relating to bullying compared to respondents not Native American. Also statistically significant was the finding of relational aggression as the primary motivation for cyberbullying perpetration among Native American respondents adhering to their tribal traditions compared to respondents not Native American, and Native American respondents that reported not adhereing to their tribal traditions. Relational Aggression is defined here as aggressive behavior with the intent to attack relationships and was operationalized by two questions addressing weakness and exclusion of the victim. Conclusions include the validity in considering effects for gender, ethnicity, and culture on rates of cyberbullying perpetration and victimization when prevention policy is being created, and as response by future research to the current dearth addressing these potential effects in the literature. Cyberharassment is the intentional use of information and communication technologies to distress an individual, and it is occasionally used interchangeably in the literature with cyberbullying. Cyberharassment is distinguishable in some State legislation from cyberbullying in that the victim of technology-based harassment is often categorized as an adult, whereas in cyberbullying legislation the victim is often distinguished as children and adolescence. Cyberstalking is generally used to describe computer-mediated acts or communications deemed as being associated with either an implied or a credible threat of violence to an undistinguished aged victim.

- Description:
- Field data collected from the consumption of organic forest soil (duff) by smoldering combustion are analyzed to determine the spatial patterns as input for a smoldering combustion model. Moisture, organic, and inorganic contents were measured at longleaf pines to detect patterns that could be used to explain the spatial patterns in post-burn consumption. The model takes these environmental predictors as input values and then outputs spatial consumption patterns. Methods are also developed to describe the two-dimensional spatial patterns of consumption created by the smoldering combustion. The spatial patterns revealed that smoldering combustion occurs most often at the base of a tree stem at the reintroduction of wildland fire in long-unburned forest. The data from the organic soil pa- rameters were unable to completely predict this behavior, indicating that other factors might be involved. Duff depth was noted as being significantly higher at the areas of smoldering initiation indicating that understanding the soil characteristics of these deep duff mounds at the tree base will help predict smoldering patterns, and therefore deserve further research.

- Description:
- The primary evolutionary goal of many hatchery supplementation programs is to minimize genetic change and fitness loss associated with captive breeding. The objective of this study was to assess the genetic stability of a hatchery steelhead (Oncorhynchus mykiss) population from the Mad River (California, USA) over 35 years of captive breeding. The genetic population structure of historical (1974-1975) and contemporary (2000-2010) hatchery and wild stocks were compared using 14 microsatellite loci. Contributions from four non-indigenous populations transplanted to the Mad River were also assessed. The founding steelhead population artificially propagated at Mad River Hatchery was resolved as genetically similar to wild steelhead from natural areas in the Mad River and those from the Eel River. From this starting point, the captive population diverged over 35 years while the wild population retained the historical condition but was also highly admixed (17-44%) with the newly formed hatchery population. Analyses indicated that contributions from non-local populations were not responsible for divergence of the hatchery population. Instead a lower effective population size in the hatchery (Ne=246-285) in comparison to the wild (Ne=1,935-4,356) and closure of the hatchery population to immigration from the wild suggests drift in isolation is responsible for divergence. The small number of spawners used in many years at the hatchery along with variance in reproductive success likely explains the observed level of drift. The evolutionary potential of both hatchery and wild populations may be constrained unless efforts are implemented to reduce divergence among them and mitigate for the deleterious effects of genetic drift in the hatchery population.

- Description:
- This article focuses on a translation of excerpts from Fiery Red Summer, an account of the Spring Offensive of 1972, by Phan Nhat Nam, South Vietnam's most famous war reporter. The introductory essay provides background on the offensive and suggests why it and the battle for An Loc, arguably the most important battle of the Vietnam War, have received little attention from U.S. historians. The translated excerpts from Fiery Red Summer that follow describe how the 6th Battalion of the 1st Airborne Brigade of the Army of the Republic of Vietnam fought bravely to link up with troops defending An Loc, thereby helping to break the communist siege of the town. Both the essay and the translation suggest that to understand an event such as the battle for An Loc one must consider multiple perspectives.

- Description:
- Studies that examine family violence assert that many abusive behaviors are transmitted intergenerationally. Investigations of intergenerational transmissions of family violence it is important to acknowledge that childhood traumatization has a significant role. This study surveyed clients of a court-ordered Batterer Intervention Program to investigate whether these clients had witnessed or experienced family violence in during childhood. The survey collected information on whether the clients’ abuse was part of an intergenerational cycle, whether clients’ children were exposed to abuse, and the effects of abuse behaviors witnessed and/or experienced as children on the abuse perpetrated as adults. Half of the clients surveyed indicated that they had been abused as children. Additionally, strong relationships were found between experiencing and witnessing abuse as children and the perpetration of abuse as adults. Intergenerational cycles were determined to be a factor among that affect men’s and women’s perpetration of family violence.

- Description:
- Efforts in 2012 represented the 17th year of restoration and associated monitoring of central California seabird colonies by the Common Murre Restoration Project (CMRP). This project was initiated in 1996 in an effort to restore breeding colonies of seabirds, especially Common Murres (Uria aalge), harmed by the 1986 Apex Houston, 1998 Command and extended Luckenbach oil spills, as well as gill net fishing, human disturbance, and other factors. From 1995 to 2005, the primary goals were to restore the previously extirpated Devil’s Slide Rock colony using social attraction techniques, and to assess restoration needs at additional central California colonies. Since 2005, efforts have been focused mainly on surveillance and assessment of human disturbance at central California Common Murre colonies. Additionally, the outcome of initial restoration efforts at Devil’s Slide Rock continues to be monitored. These data inform outreach, education and regulatory efforts by the Seabird Protection Network (coordinated by the Gulf of the Farallones National Marine Sanctuary) and allows for assessment of the success of those efforts. The goal of the Seabird Protection Network is to restore central California breeding colonies, primarily through reduction of human disturbance, to compensate for losses during the Luckenbach and Command oil spills. Surveillance and monitoring were conducted almost daily from mid-April to mid-August at the following Common Murre colonies in central California: Point Reyes, Devil’s Slide Rock & Mainland, and the Castle-Hurricane Colony Complex. Another four colonies were surveyed weekly or bi-weekly including three in the Drakes Bay area (Point Resistance, Millers Point Rocks, and Double Point Rocks). Human disturbance rates associated with planes, helicopters, and watercraft were calculated. Seasonal attendance patterns, productivity, adult co-attendance patterns (the percentage of observation time that both parents are present at a nest site) and reproductive performance of Common Murres were also assessed. Additionally, population sizes and/or productivity of five other seabird species were assessed. Bird and nest counts were conducted three times per week at Bird Island and once per week at San Pedro Rock. Detections of aircraft and watercraft (boats) and associated disturbances are reported as a rate per observation hour and compared to a baseline (average of 2005-2006 rates). At Point Reyes, the combined aircraft and boat detection rate was less than the baseline mean (including aircraft, boats, and other), but greater than in 2011. The combined disturbance rate was less than any year since 2002. Detection and disturbance rates at Drakes Bay colonies were also less than the baseline mean, with no observed disturbance events. Devil’s Slide Rock & Mainland (DSRM) continued to have the greatest combined aircraft and boat detection and disturbance rates of all colonies. At DSRM, overall detection and disturbance rates were the greatest recorded to date, largely due to fixed-wing aircraft rates. Most disturbances were agitation events (i.e., no flushing or displacement) but several flushing events occurred, mostly from low helicopter overflights. At the Castle-Hurricane Colony Complex, the combined aircraft and boat detection rate was the least since 2007, but the disturbance rate was slightly greater than the baseline mean (but less than in 2011). xiv Unmarked planes and helicopters (e.g., private or charter), followed by military aircraft, were the most commonly observed aircraft and caused the majority of disturbances at all monitored colonies. The majority of watercraft observed were small private recreational boats (68%) followed by sailboats (11%). One small fishing boat at DSRM was responsible for the only boat-related disturbance. Four vessels were recorded inside state Special Closures at Devil’s Slide Rock and Double Point Rocks/Stormy Stack, but only one resulted in disturbance to seabirds. The peak count of 1,499 Common Murres on Devil’s Slide Rock was 70% greater than the 2011 peak count, and greater than the previous record count of 1,003 murres recorded in 2009. Murre productivity, or reproductive success, was greater than average at Devil’s Slide Rock and Castle Rocks & Mainland despite some Brown Pelican disturbance. Major and prolonged disturbances from Brown Pelicans (Pelecanus occidentalis) at Point Reyes Headlands, Point Resistance, and Double Point Rocks resulted in near total murre reproductive failure. Infrequent co-attendance of murre breeding pairs during the chick-rearing period at Devil’s Slide Rock indicated that murres spent a substantial amount of time foraging to provision young. There were fewer Brandt’s Cormorant (Phalacrocorax penicillatus) nests counted in 2012 than in 2011 at all colony complexes but CHCC. Productivity in 2012 was also less than in both 2011 and the long-term means at all monitored colonies. Numbers of Pelagic Cormorant (Phalacrocorax pelagicus) appeared to be relatively great but productivity at Devil’s Slide Rock and Mainland was the less than any other year on record. Productivity of Western Gulls (Larus occidentalis) was monitored only at DSRM and CHCC. Numbers of breeding Western Gulls were more variable among colonies than in 2011, and productivity of monitored nests was relatively low.

- Description:
- A sample of sixteen homicides occurring in Humboldt County, California was used to compare the Times-Standard’s treatment of homicides in 1982, 1995, and 2009. The sample examined eight homicide cases involving a Native American victim or suspect and eight cases which did not involve a Native American victim or suspect. Through the use of the qualitative research method, ethnographic content analysis, three protocols were developed for the process of analyzing the sample. Protocol I found articles without Native American Identifier (NAI) had more pictures than articles with NAI. Protocol II focused on use of kill words in the articles. The word killer was most frequently applied to articles without NAI. Protocol III looked at descriptions of victims and suspects through the lens of victimized, eulogized, criticized, authorized, and criminalized language in the Times-Standard. Victims without NAI were more frequently eulogized and less likely to be criticized or criminalized. Victims with NAI were more frequently criticized, authorized, or criminalized for their deaths. Suspects with and without NAI were equally criminalized and criticized. When a homicide involved a victim with NAI and a suspect without, it was more common for the suspect to be authorized for their actions, than when the victim and suspect did not have NAI. Suspects with NAI were less likely to be victimized compared to suspects without NAI.

- Description:
- In this study, two ways of accumulating Pb were investigated: natural accumulation and chemically enhanced accumulation with the chelating agent ethylenediaminetetraacetic acid (EDTA). Young cattails (Typha latifolia) were removed from the Arcata Community Pond in Northern California and transplanted into two-quart mason jars containing four different levels of Pb contamination: 0, 2000, 4000, and 6000 mg Pb/kg soil. Three cattails per jar were grown for a three-week period with half of the plants receiving 10 mmol EDTA on the 15th day of the experiment and allowed to continue growth for the remaining 6 days of treatment. Cattails were harvested, separated into shoots, rhizomes and roots, and then analyzed for Pb concentration in these tissues using Atomic Absorption Spectrophotometry (AAS). For the natural accumulation of Pb, no significant differences among the 2000, 4000, and 6000 mg Pb/kg groups for shoots (p = 0.1063), rhizomes (p = 0.1096) or roots (p = 0.2526) were detected. When EDTA was added to the soil, there was a significant difference among the various levels of soil contamination (p = 0.0002). In this particular case, the largest accumulation of Pb occurred at the 4000 mg Pb/kg soil contamination level with shoots accumulating a combined average of 4744.03 mg Pb/kg. These results show that three cattails can remove Pb from the environment in larger quantities if a chelating agent is present in a short period of time. In addition, it appears that the 6000 mg Pb/kg soil contamination is a threshold of toxicity as all aspects of the experiment showed a decrease in the health, natural accumulation of Pb, and the accumulation of Pb with the addition of EDTA. Typha latifolia has a wide tolerance to many different environments and produces a large amount of biomass, which make it a good candidate for use in phytoremediation. Further research should consider increasing the quantity of cattails to optimize Pb removal from the soil.

- Description:
- The purpose of this study was to examine mental health factors including substance use, depression, caretaker bonding, and social self-efficacy in individuals who were previously placed in foster care. This study sought to compare outcomes in those former foster care recipients who experienced relative and non-relative adoption. A total of 185 former foster care recipients participated in the current study. Results indicated that individuals who experienced adoption out of foster care by a relative have lower depression levels and higher ratings of social self-efficacy than those who were adopted by a non-relative and those who were never adopted out of care. The present study found results in low levels of substance use which were relatively equal among these three groups. Additionally, this study found the highest levels of female caretaker bonding in those foster care recipients who had been adopted by a relative as compared to individuals who were adopted by a non-relative and those who were never adopted, however no significant difference was found in the ratings of male caretaker bonding between groups. Data were collected through the use of The Substance Use Inventory, the Hamilton Depression Inventory, the Parental Bonding Instrument-Foster Care, the Social Self-Efficacy Subscale of the Sherer’s perceived Self-Efficacy Scale, and a brief demographic questionnaire.

- Description:
- I studied sage grouse (Centrocercus urophasianus) nesting habitat from mid-March through mid-August of 1998-2000 in eastern Lassen County, California. I located nest sites of forty-five radio-marked hens. To evaluate habitat selection I measured vegetation at each nest site and at random sites. Sage grouse avoided low sagebrush (Artemisia arbuscula) cover type for nesting. They used big sagebrush (Artemisia tridentata) cover type and mixed shrub cover type in proportion to their availability. In addition, grouse used diverse sites for nesting as indicated by among nest site variation being similar to variation between nest and random site variables. Likewise, there were habitat differences between successful nests and unsuccessful nests. Mean nest-lek distance was greater for successful nests (x̄=3588 m, SE=811, n=20, P=0.06) than the nest-lek distance for unsuccessful nests (x̄=1964 m, SE=386, n=20). Rock cover was greater at successful nests (x̄=27.67%, SE=4.6%, P=0.04) than at unsuccessful nests (x̄=14.49%, SE=3.04%). Total shrub height was greater at successful nests (x̄=65.5 cm, SE=4.7, P<0.01) than unsuccessful nests (x̄=49.2 cm, SE=1.7). The height of visual obstruction was greater at successful nests (x̄=40.2 cm, SE=2.6, P=0.02) than at unsuccessful nests (x̄=32.5 cm, SE=2.0). Greater distance from the lek, total shrub height, rock cover, and visual obstruction appeared to characterize successful nests compared to unsuccessful nests. My results suggest that rangeland managers should strive for both landscape and microsite heterogeneity.

- Description:
- 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.

- Description:
- For over a century, salmonids have been stocked in historically fishless, montane lakes for the sole purpose of creating recreational fishing opportunities. Salmonid introductions have had transformative impacts on historically fishless systems where native biological communities had previously been isolated and evolved without the presence of fish. While certain communities consider fishing for stocked trout a traditional and important use of wilderness, others are concerned with the impacts of introduced salmonids on the region’s biological integrity. As management shifts from continued stocking practices toward a focus on ecological restoration, communities with differing ecological values and priorities must compromise on management of high-elevation ecosystems by utilizing a socioecological approach. This research addresses the need for human dimensions research to understand social conflict among stakeholder communities. The recreation-biodiversity conflict surrounding the revaluation of high-elevation stocking programs has arisen in part due to diverging valuations of wilderness, a lack of substantial educational outreach, and a lack of mutual trust between stakeholders. This research uses Q methodology, a qualiquantilogical method, to examine stakeholder opinions on fish stocking and the use of fish removals as ecosystem restoration. Through an inverted factor analysis, Q method has clustered participants by perspective into four factors—1) Pro-Restoration, 2) Collaborators, 3) Legacy, and 4) Extreme Pro-Restoration. Q method facilitates discovery of collective agreement, while also revealing key differences among perspectives, which are integral to delineating conflict and developing solutions for environmental concerns. This research is a call-to-action for stakeholders to develop mutual trust through transparent communication and inclusive engagement.

- Description:
- The purpose of my project is to provide both a report of the 2005 Expanding Your Horizons (EYH) conference and a longitudinal evaluation of the effects that past EYH Conferences have had for middle school girls in Northern California. The goal of each conference is to get girls to take more math and science in high school so they have more options later on in life. The 2005 report will examine both the demographics of the participants and their evaluations of the conference. The longitudinal portion will assist the local AAUW branch in determining how to best allocate their resources by examining whether or not past EYH attendees did take more math and science in high school compared to girls who never attended a conference. This information will aid in the future planning of conferences to ensure that AAUW’s goal of encouraging girls to explore and pursue careers in math and science.

- The majority of world language programs in the United States are offered to students beginning in high school, an earlier start in middle school gives students the opportunity to lengthen their course of study, and attain higher proficiency in a world language. This qualitative study investigates the perceptions of middle school students who attend a small, rural K-8 school, toward the learning of Spanish. Student responses to open ended questions from focus groups are used to inform the research. Themes include attitudes toward learning Spanish, students’ perceived purpose and learning objectives, preferential instructional activities and formats, and affective factors such as motivation and frustration. Results indicate that these middle school students desire an instructional format that is communicative-based and parallels the Natural Approach to second language learning.

- Description:
- In temperate coniferous forests, forest floor fuels have been linked to variation in important effects of fire, most notably mineral soil heating and post-fire tree mortality. To improve the understanding of fire effects, I collected forest floor fuels in long-unburned Jeffrey pine (Pinus jeffreyi) - white fir (Abies concolor) forests of the Lake Tahoe Basin, USA. Fuels from each forest floor horizon (litter, fermentation, and humus), as well as other important woody fuels (1-hour fuel, 10-hour fuel, and cones), were collected around the bases of large (> 50 cm diameter) Jeffrey pine and white fir. To isolate the effects of spatial position, I quantified fuel loading, depth, and bulk density at the base of each tree, beneath the crown drip line, and beyond the crown in open “gaps”. Seasonal fuel moisture trends were measured during the 2009 and 2010 fire seasons. To understand the structure of the litter horizon, both spatially and between species, litter composition was examined, and mineral ash contents of each forest floor horizon were measured. Little variation was detected in forest floor bulk densities, depths, and moisture contents between the two conifers. There was also little variability in forest floor moisture across the Lake Tahoe Basin, but isolated rainfall events significantly altered forest floor moisture patterns. Duff (the fermentation and humus) moisture varied spatially throughout stands, whereas other important forest floor components did not. Results from the interannual moisture study revealed that moisture of the forest floor horizons differed between years while woody fuel moisture did not. The variability in field results underscore the importance of measuring duff moisture content, as well as 10-hour woody fuel moisture, prior to prescribed fire. Forest floor bulk density and depth did not differ between Jeffrey pine and white fir. However, Jeffrey pine forest floors were more flammable than white fir forest floors in the laboratory, where samples of forest floor litter were burned under controlled conditions. Forest floor fires beneath Jeffrey pines could potentially burn at greater intensities and smolder longer than white fir forest floors due to differences in burning characteristics. In the Tahoe Basin, a better understanding of the complexity of forest fuels will help land managers manage and restore these fire-prone forests. More broadly, these results help inform the understanding of fuels dynamics in other temperate coniferous forests.

- Description:
- This project sought to lay the groundwork for an outreach effort by CASA of Humboldt to better communicate with community professionals (care providers, teachers and school staff, medical and mental health providers, social workers, probation officers, and other court personnel.) Through a community survey it was discovered that both electronic training materials such as a YouTube video and the option of in person trainings were preferred by community professionals. Additionally the survey revealed that community professionals did not fully understand the role of a CASA advocate and were not fully comfortable working with a CASA advocate. This project makes recommendations to CASA of Humboldt to improve their outreach to community professionals and makes recommendations to future MSW students who may want to continue working on this issue.

- Description:
- A Geographic Information System (GIS) was used to build the Health Risk Tool, a decision support tool to model objective health risk. The model was developed using Esri ArcGIS 10.0 and Python 2.6. The tool allows users to customize and implement a dynamic health risk analysis model as a toolbox within the ArcGIS software environment. Users may specify the weights for each risk factor contributing to the model. The tool provides a scientifically-based model using consistent methodology to generate geospatially-explicit results and visualizations. These model outputs are useful to healthcare researchers, planners, and other professionals for prioritization of community health risk (in this case study, for the prioritization of type 2 diabetes patient nonadherence risk in Humboldt County).

- The purpose of this study was to understand how alexithymic characteristics relate to help seeking behavior. Additionally, this study sought to measure the levels of alexithymic characteristics between men and women and how they related to help seeking behavior in relation to mental health services. The Toronto Alexithymia Scale (TAS-20) was used to measure alexithymic characteristics and the Inventory of Attitudes toward Seeking Mental Health Services (IASMHS) was used to measure help seeking behavior in relation to mental health services. For this study, 65 individuals (15 men and 50 women) participated. The results show that higher alexithymic characteristics relate to lower scores in help seeking behavior. In this study, no statistically significant difference was found between men and women in their IASMHS scores. Additionally, no significant interaction was found between gender and alexithymic characteristics on the IASMHS. In sum, this means that when people report higher alexithymic scores, they have a lower likelihood of seeking mental health services. This study tries to provide information to counselors as to what might be one of the resons people with alexithymic chaeacteristics do not seek counseling or stay in counseling.

- Description:
- This investigation attempts to characterize the flow of quality assurance information in Kenya's off-grid lighting market in order to identify key opportunities for improving access to product information throughout the supply chain. While traditional energy access strategies have focused primarily on rural electrification, distributed generation strategies through solar lanterns, solar home systems, and micro-grids are gaining more visibility and consideration as viable alternatives to their fossil-fueled analogs. However, there is a recognized need for greater institutional support to avoid market spoilage and encourage adoption of these nascent technologies in virgin markets. In response to this need, Lighting Global has created a quality assurance framework to monitor the quality of solar products in off-grid markets and communicate this information to market stakeholders. Distributors, wholesale traders, retailers, customers, and other stakeholders were interviewed to better understand how buyers make purchasing decisions and how access to quality assurance information could be improved through mechanisms like product testing reports, on-the-box labeling, or illustrated flip-books. This research finds that solar products are now a dominant presence in off-grid markets in Kenya, capturing iii approximately 80% of the market share by sales revenue in the towns that were surveyed. A variety of information signals were observed in the market, including brandrecognition, word-of-mouth referrals, and on-the-box product performance claims. Simplified product specification sheets and illustrated flip books were identified as the mediums preferred by retailers for learning more about solar products and educating customers. While many of the observed signals reduce uncertainty for end-users, quality signals like warranties, quality seals, or consumer financing were determined to play unique roles in reducing risk for potential solar customers. With increased digital literacy and mobile coverage in Kenya, mobile-friendly websites and social media applications were highlighted as opportunities for engaging and sharing quality assurance information with retailers and end-users further down the supply chain.

- Description:
- Maximum entropy estimation is a non-parametric method of determining probability distributions from limited information. In the field of ecology, maximum entropy estimation has seen use in the last 10 to 15 years as a method for developing macroecoogical models. Some macroecoogical metrics, such as the intraspecific spatial abundance distribution and the range-area relationship, and methods, such as setting out a grid and counting individuals, are much more easily applied to plants than animals. However, some animal species do lend themselves to this technique, making it possible to determine these metrics. The giant kangaroo rat (Dipodomys ingens) is one such species, with large burrows that are easily identifiable from aerial photography. This provides an opportunity to test out the applicability of the maximum entropy model for the spatial abundance distribution and the range-area relationship, and compare it to the earlier Coleman random placement model. Scale is found to have a significant effect in the applicability of the maximum entropy model, while the Coleman random placement model fits well across a greater range of scales. In addition, it is shown that the Coleman random placement model can be used to estimate the total number of burrows in an area from limited data, with varying accuracy depending on scale.

- Description:
- Improved understanding of the importance of estuarine wetlands to the function of coastal ecosystems has lead to increased restoration efforts of degraded wetlands. The South Slough National Estuarine Research Reserve (SSNERR) in Coos Bay, Oregon, has taken active steps to restore previously diked tidal wetlands. In addition, they have established monitoring programs that focus on the faunal and floral recovery of restored sites within Kunz Marsh. The overall objective of the present study was to determine the degree of community recovery in restored salt marsh sites relative to control sites. Vascular plants, diatoms, invertebrates, and fish were sampled in spring, summer, and fall of 1998 and 1999. Vegetation cover decreased from high to low elevations, was higher in control than restored sites, and increased between 1998 and 1999. Diatom abundances showed seasonality in most sites and were higher in the restored than the control sites. Relative abundance of invertebrates in the first year was higher in control than in restored sites. More of these animals were found in vegetated than open areas. Fish abundance increased with decreasing elevation and Kunz Marsh sites showed a species composition similar to the adjoining Winchester Creek. In general, community recovery, particularly for plants and invertebrates, occurred more quickly in the higher restored sites. This may be due to the aggressive restoration method used, as well as successional processes that are known to occur more rapidly in the high marsh.

37. Variation in diet and activity of river otters (Lontra canadensis) by season and aquatic community
- Creator:

- Description:
- Keystone predators can impact many prey species, including those that are endangered. In order to assess the impact predators have on different prey populations, it is essential to identify the species being consumed in different types of aquatic communities, while accounting for possible seasonal variation in consumption. Here I use analysis of river otter (Lontra canadensis) scat to assess the impact otters have on prey populations, particularly endangered salmonids and migrating birds. I analyzed the prey composition of 1,411 river otter scats collected from 10 sites in Humboldt County, California, between 2011 and 2012. Analysis of prey items in scat divided study sites into four distinct clusters based on diet. Fish, particularly from the families Gasterosteidae (sticklebacks), Cottidae (sculpins), and Pholidae (gunnels), formed the main prey component, but crustaceans, birds (Anas sp. and Fulica sp.), amphibians, and insects were also main components of otter diet. Salmonids formed less than 5% of overall diet, but otters consumed the largest percentage of salmon during salmon spawning season at the inland cluster where salmonids spawn. Scat marking intensity varied between latrine sites, clusters, and seasons, with the most scats collected in the fall and the fewest in the winter/spring, except at the inland cluster where marking activity was reversed. Otters may be responding to seasonal migrations of endangered and threatened salmonids. Birds comprised 21% of diet and were eaten most frequently during the winter migration season, and no endangered bird species were found. Diet surveys of this type are useful for monitoring resource use by top predators in wetlands and other aquatic ecosystems.

- Description:
- Scent-marking, the deposition of a scent-containing excretion as a means of intraspecific olfactory communication, is common among mammals. For the North American river otter (Lontra canadensis) the latrine serves as a primary area for scent-marking where they regularly deposit scat, urine, and anal sac secretions. Latrine sites provide an efficient means for the indirect study of river otter ecology. This study was conducted on the river otter population located in the Humboldt Bay region of northern California. There were two main areas of focus: the evaluation of otter latrine site selection and examining trends in scent mark deposition at latrines. Paired logistic regression was used to compare models of habitat characteristics present at latrine sites to those at nonlatrine sites, identifying features selected for by river otters in the establishment of latrines. River otters selected for the presence of fallen logs as well as greater water depths and shore heights for the establishment of latrines across the study area. In more forested habitats, greater canopy cover was also selected for latrine establishment. The number of otter scent marks occurring at latrines located in different habitat types was recorded biweekly over the course of a year. Latrine use was compared among habitats using Poisson regression in a mixed model approach, testing the hypothesis that seasonal patterns of habitat use by river otters existed within the study area. Overall trends in seasonal scent mark deposition by river otters at latrines were similar to those found in previous studies, with peaks occurring in the spring and fall. Results suggested that seasonal fluctuations of several prey species influenced the use of habitats by river otters. Information gained through this study may benefit future research efforts by speeding the process of locating river otter latrines, allowing search efforts to focus on areas containing habitat features selected by otters. Seasonal peaks in scent-mark deposition at latrines may also provide optimal times for locating latrine sites and collecting scent marks for use in diet or demography studies. Evidence of seasonal habitat use by river otters provides insight into otter ecology and may also aid future research and land management activities.

- Description:
- Although college students have access to many free or low-cost services, a majority do not take advantage of these resources. For decades, researchers have sought solutions to this misalignment of service availability, need, and utilization. Impeding this goal is the lack of a sufficiently broad psychometric instrument that can measure and predict help-seeking in an individual. At this time, no such measure currently exists. The purpose of this study was to develop the College Help-Seeking Behavior Scale (CHSB) to assess college students’ intention and past behavior regarding seeking help from social networks and on-campus services for various problems.

- Description:
- Adult female Dungeness crabs (Cancer magister) can be inseminated only while in a soft-shell condition immediately after molting. Population modelers have therefore assumed that all adult female Dungeness crabs undergo an annual molt. Based on this assumption, a tag-recovery project was initiated in northern California to determine demographic statistics of the adult female stock. Of 12,037 adult female crabs tagged and released, recoveries of 492 crabs in the commercial fishery showed that a large proportion of adult female Dungeness crabs fail to molt annually and that extrusion of viable eggs does not require annual molting and mating. A size-specific annual molting probability estimator was developed which accounts for commercial gear selection biases. Estimates using this technique showed that annual molting probabilities decline with increasing adult female size and become zero above 155 mm. Therefore, size and age are weakly correlated. Size-related population statistics are probably more meaningful than age-related statistics because molt increments and molting probabilities appear to be more dependent on size than age. Width frequency distribution separation failed to allow year class strength extraction and size-specific survival rate estimation. However, comparisons of width frequency histograms across years show apparent variation in year class strength. Tag-recoveries provided an annual survival rate estimate of 0.2 for crabs fully vulnerable to the commercial gear (> 155 mm). Truncation of width frequency distributions over larger female sizes suggests that survival rates for smaller female crabs are greater. The extremely low survival rate and the cessation of molting for large adult females imply that adult female Dungeness crabs may become senescent after reaching a terminal size.

- Description:
- Idealism is defined as believing that desirable consequences can, with the “right” action, always be obtained. This involves decreasing the amount of negative outcomes and increasing the amount of positive outcomes. Due to the lack of a reliable and valid existing measure of idealism, our goal was to create a psychometrically sound scale. Morality and justice are two important domains that were addressed during item creation. The HIQ was compared to the Global Belief in a Just World Scale in order to establish criterion validity; the short form of the Marlowe-Crowne Social Desirability Scale was used for discriminant validity.

- Description:
- Potential long term neurocognitive (NC) and psychological effects from exposure to concussive and subconcussive forces are of growing international concern. Athletes with a history of prior concussions exhibit lower objective performances and higher symptom reporting when compared to those with fewer injuries. Due to this observation, researchers have hypothesized a dose-response relationship between concussion history and decrements in NC function. For this study, we hypothesized an association between a history of multiple concussions and NC deficits in current soccer and football participants. Those with three or more concussions were predicted to perform worse than those with no prior injuries before an athletic season and experience NC decrements after a season. Athletes (n=101) from 5 high schools and one NCAA Division II university in Humboldt and Del Norte Counties were administered a computerized neurocognitive test with related demographics (ImPACT) and asked to self-report symptoms (PCSS) immediately before and after a competitive athletic season, and were administered an additional survey related to concussion history postseason. A FOUR (concussion history-0, 1, 2, 3 or more) X TWO (time- preseason, postseason) MANOVA was used to analyze ImPACT composite and PCSS scores between the concussion groups and between preseason vs. postseason. Athletes with three or more concussions (n=13) did not obtain lower preseason (baseline) scores than athletes without a history of concussion (n=53) and there were no significant changes from preseason to postseason composite scores across any concussion group. While findings from this study did not show significant changes in NC scores after a single competitive soccer or football season, there were observed trends that shed light on the importance of comprehensive large scale longitudinal studies.

47. Reproductive isolation in five hybridizing species of western gooseberries (Ribes: Grossulariaceae)
- Creator:
- Kalt, Jennifer L.
- Description:
- Five species of western gooseberries (Ribes: Grossulariaceae) hybridize to varying degrees in northwestern California and southwestern Oregon. Pollinator surveys and hand-pollination experiments were conducted to identify reproductive barriers between the species pairs. I found little evidence of isolation due to pollinator behavior, since the five species tended to attract the same pollinators. My attempts to assess the level of post-pollination isolation were hindered by high rates of fruit abortion. Nevertheless, it appears that R. roezlii and R. menziesii are fully interfertile, and that unilateral barriers operate when R. lobbii, which has the longest styles of the set, is the maternal parent in crosses with the other species. Since the level of post-pollination isolation is not correlated with the observed frequency of hybridization in the field, ecological and/or geographical differences may play the most important role in isolating the species.

- Description:
- Interviews were conducted at thirteen Northern California museums, which were selected because of their Native American collections and programming. The purpose of the field research was to determine the philosophies of the museums in connection with two questions: "Who owns Native American Artifacts" and "Are Native Americans involved in museum programming?" The introduction discusses the current political controversy concerning museum policies of holding artifacts which may have been wrongly taken from other cultures. It was found as a result of the field research that only one of the Northern California museum administrators interviewed felt that the artifacts belonged to the originating culture, and six out of the thirteen museums visited had involved Native American leaders in their interactive programs in the last few years. Various interactive programs are described which show great creativity in the involvement of Native American presenters-- artists, story-tellers, writers, weavers, historians, dancers, and spiritual leaders. The field researcher found an unexpected relationship between the association of museums with colleges or universities and an increased use of Native Americans in high quality museum programming. This relationship can be explored in further research. Recommendations are made to educate museum professionals in the area of political sensitivity to Native American leadership and ownership of artifacts.

- Description:
- The subject of this work is the life and career of Hans Richter (1843-1916), an eminent Austro-Hungarian conductor who specialized in interpretations of German Romantic music written during the second half of the nineteenth century. Primary focus will be on the first ten years (1877-86) of his thirty-five-year career as a conductor in England. The Richter Concerts, his series of London orchestral performances between 1879 and 1902, receive the most detailed coverage, while his activities as conductor of the Vienna Philharmonic Orchestra (1875-98) are only covered where relevant. Among the areas discussed are the repertoire performed at his concerts, its reception by music critics and the public, and the similarities between Richter's London and Vienna repertoire. Richter's efforts on behalf of British music will also be considered, in terms of his direct support for native composers and his contribution to the elevation of performance standards at English concerts. His relationships with composers will be explored as they relate to performances of their music.

- Description:
- Point data that are collected during a soil survey are aggregated into conceptual map units and portrayed on maps. There is no extensive geographic method to provide information about the relationships between soil-forming factors and soil properties. These relationships are developed and used intuitively by soil scientists during a soil survey to guide map creation. This project tested the use of statistical modeling techniques and point soil data collected in a National Cooperative Soil Survey project to estimate the functional relationships between soil-forming factors and soil properties. These relationships could help increase efficiency and reduce cost of sampling in adjacent soil survey projects. Point soil data and generalized linear models were used to estimate these relationships. A geographic information system was used to algebraically combine classified soil-forming factor data layers. The resulting maps are a continuous estimation of the probability of the presence of three different soil properties. The probability maps were combined with mapped soils to compare the probabilities to mapped likelihoods of soil properties. One of the models appeared to provide reliable insights into relationships. The other two did not. Additional soil-forming factor data are needed.
