An Analysis Of An Andean Cosmovisión: Nature, Culture, Ecology, And Cosmos, Christian Ardeleanu

Master's Theses

Modern life may offer certain benefits for humanity, but it can also create a barrier between humans and the natural world. In contrast, the millenarian Aymara culture of the Bolivian Andes exhibits a harmonic interrelation with nature, ecology, and the cosmos, and it also represents a living system of indigenous knowledge and knowledge production/transformation. The Aymara system of knowing and knowledge production, like other indigenous systems, should not be mistaken for antiquated elements of culture and folklore but should be seen as a distinct and dynamic epistemology. The Aymara cosmovisión is similar to the philosophy of ecology, sharing some general …

Environmental Education As A Catalyst For Changing Students' Environmental Attitudes: A Survey Of Ten Universities In The Tokyo Bay And San Francisco Bay Areas, Minako Nishiyama

Master's Theses

Environmental education has been internationally recognized as a key tool to counter increasing threats to the environment. Previous studies have found that environmental values and beliefs are the fundamental factors that shape various pro-environmental behaviors. This study aimed to increase our understanding of how environmental education during childhood and university periods influence students' sense of connectedness to nature and ecological worldview. Two measures, the Connectedness to Nature Scale (CNS) and the New Ecological Paradigm (NEP) scale, were used for this purpose. A total of 1,266 students in 10 universities in the San Francisco Bay Area and Tokyo Bay Area participated …

An Investigation Of Coastal Groundwater Discharge And Associated Nutrient Inputs Using Electrical Resistivity, Temperature, And Geochemical Tracers In Pescadero Lagoon, California, Christina Maryann Volpi

Master's Theses

Pescadero Lagoon is a complex lagoon system located on the central California coast in San Mateo County. Over the last decade, external stressors such as degraded water quality, restricted circulation, heightened groundwater withdrawals, changes in the fluvial geomorphology that affect surface water runoff, and widespread agriculture in the watershed have impacted the lagoon. The lagoon system is bounded on the marine side by an ephemeral sand berm that is seasonally closed and so hinders open exchange with the ocean. This berm and the Mediterranean-type climate play an important role in the lagoon's circulation and water quality. The most high-profile and …

Pathway To The Podium: Situating Rhetorical Agency Within The Tommie Smith And John Carlos 1968 Mexico City Olympic Protest, Andrew Carter

Master's Theses

The recent romanticization and celebration of the Tommie Smith and John Carlos 1968 Mexico City Olympic Protest has allowed contemporary American society to recognize both athletes as heroes and pioneers within the Civil Rights movement. They have been honored with of a number of awards both nationally and internationally, as well as memorialized with a 22-foot high statue that was erected on the campus of San José State University in 2005. From once being ostracized as national villains, Smith and Carlos have come full circle in how they are referenced within public consciousness. However this recent transformation on the part …

Native American Response And Resistance To Spanish Conquest In The San Francisco Bay Area 1769-1846, Gustavo Adolfo Flores

Master's Theses

This study focuses on how secular, governmental, and ecclesiastical Hispanic Empire institutions influenced the response and resistance of San Francisco Native American groups from 1769 to 1846. This project draws on late 18th and early 19th century primary Spanish documents and secondary sources to help understand the context of indigenous people's adaptive and response behaviors during this period as well as the nuances of their perspective and experience. Using both electronic and physical documents from a number of archival databases, primary Spanish documents were translated and correlated with baptismal and death mission records. This allowed for formulating alternative perspectives and …

Novel Bacterial Lineages In The Uncultured Candidate Division Sr1, Sumreet Kaur Ghotra

Master's Theses

Complex and naturally occurring microbial communities are known to be predominantly composed of uncultured bacteria and archaea. A few representatives of uncultured prokaryotes (e.g., from the candidate divisions TM7 and SR1) have been found in environmental samples and in association with animals, including humans. It is not yet clear, however, how uncultured bacteria found at environmental sites relate phylogenetically to their counterparts associated with animal hosts. In this study, we investigated the diversity of the SR1 candidate division to better understand the divide between animal-associated and environmental lineages. We generated 16S rDNA gene clone libraries from samples obtained from the …

The Response Of Bats To Introduced Trout In Naturally Fishless Lakes Sierra Nevada, California, Elizabeth Gruenstein

Master's Theses

Stocking of trout into naturally fishless water bodies in the mountains of western North America has reduced populations of many native species in those systems, with benthic aquatic invertebrates being particularly impacted. Although bats are known consumers of emergent aquatic insects, almost no studies have focused on how changes to these prey populations at lakes subsequent to trout stocking could affect them. This study assessed bat activity, foraging activity, and foraging rate at nine feature-matched pairs of stocked and unstocked high elevation lakes in the central Sierra Nevada mountains in an effort to determine which provide higher quality foraging habitat …

Mapping The Monster: Locating The Other In The Labyrinth Of Hybridity, Jill Kristine Harper

Master's Theses

By the last two decades of the nineteenth century, Great Britain led the European contest for imperial dominion and successfully extended its influence throughout Africa, the Americas, South East Asia, and the Pacific. National pride in the world's leading empire, however, was laced with an increasing anxiety regarding the unbridled frontier and the hybridization of Englishness and the socio-ethnic and cultural Other. H. Rider Haggard's She, Bram Stoker's Dracula, and Richard Marsh's The Beetle, three Imperial Gothic novels, personify the monstrosity of hybridity in antagonists who embody multiple races and cultures. Moreover, as representatives of various ancient …

Teaching English As A Second Language Through Rap Music: A Curriculum For Secondary School Students, Beth Segal

Master's Theses

This project provides a sample of the curriculum, Rapping English, which uses rap/hip-hop style music to teach ELLs vocabulary, grammar, discourse and prosody. The rationale for using musical instruction is based on Gardner’s (2006) multiple intelligence theory and Bloom’s (1978) learning domains. This curriculum instructs students through musical intelligence and the affective domain which are often neglected in traditional instruction. Furthermore, this project explores how musical curriculum can be used to lower the affective filter (Krashen, 1981) and provide emotionally appealing and memory stimulating instruction in line with the findings of current neuropsychology, specifically the work of R. Caine and …

This paper examines the discrimination faced by the LGBTI community in Cameroon by exploring the origins of homophobic violence, the role played by Cameroon's legal system, and the struggles of LGBTI Cameroonians in their fight for a better life. The analysis includes a review of the work by scholars on colonialism and sexuality in Africa, and questions the roots of violence and abuse against the LGBTI community …

Raindrop Imprints And Their Use In The Retrodeformation Of Carboniferous Trace Fossils, Meredith Fichman

Master's Theses

The Narragansett Basin of Massachusetts and Rhode Island is a Carboniferous terrestrial basin and is the only location within New England that preserves fossil evidence of early amphibians and reptilomorphs. Footprints and trackways constitute the only record of these early tetrapods, but deformation during the Alleghanian orogeny has distorted the traces. To improve identification, description, and comparison with non-distorted material, tracks from Plainville, Massachusetts were retrodeformed using raindrop imprints as strain markers.

The axial ratios of 354 raindrop imprints found on 12 slabs were analyzed using the Rf/Φ technique. Strain ratios for slabs ranged from 1.33 to 1.93, with individual …

The Behavioral And Physiological Effects Of Long-Distance Translocation On Western Rattlesnakes (Crotalus Oreganus), Kory Hayden Heiken

Master's Theses

Long-distance translocation (LDT), the relocation of an animal outside of its home range, is a popular strategy for mitigating conflict between humans and venomous snakes. While LDT has been demonstrated to prevent a snake’s return to the location of capture, it may result in increased mortality, magnitude and frequency of movements, and activity range sizes. Thus, it has generally been discouraged. However, the effects of LDT on stress physiology and thermoregulation have gone largely unstudied in reptiles. To elucidate these effects, we conducted an experimental LDT on Western Rattlesnakes (Crotalus oreganus) on Vandenberg Air Force base in California. …

Design Of A Low Power Cargo Security Device Using A Micropower Ultra-Wideband Impulse Radar, Brian M. Wihl

Master's Theses

Each year, thousands of cargo containers are broken into during shipping, costing billions of dollars in lost and damaged goods. In addition to removing its contents, intruders can also add unwanted and dangerous materials to a container, posing a threat to National Security. The possibilities of cargo container break-ins require that the containers go through check points at which they are physically searched. These searches often require the opening of the container, unloading and inspecting all cargo, and then loading the container and resealing it. This is a long and costly process.

Because of the high costs of break-ins and …

Field Dection Device Of Reactive Oxygen Species, Danielle Lee Cowgill

Master's Theses

Traumatic brain injuries (TBIs) contribute to approximately 30.5% of all injury related deaths in the United States per year and approximately 1.7 million TBIs per year occur as an isolated injury or other injury. Military personnel are exposed to TBIs and have less availability to resources traditionally used to diagnose a TBI. Reactive oxygen species (ROS) play a large role in secondary traumatic brain damage, especially lipid peroxidation, following TBIs. One of the principle and most studied byproducts of lipid peroxidation is malondialdehyde (MDA). The focus of this paper was to create an initial proof-of-concept field diagnostic device to detect …

Stimulant Use, Associated Psychopathology, And Eating Disordered Symptomatology, Tiffany Ann Hopkins

Master's Theses

The current study developed profiles of eating disorder, personality, and other psychopathological symptoms related to the use of central nervous system stimulants versus other types of drug use. Participants included 124 women in residential treatment for substance use with and without comorbid eating disorders. Symptomatology was measured by the Eating Disorders lnventory-3 (EDI-3), Millon Multiaxial Inventory-III (MCMI-III), and Personality Assessment Inventory (PAl). The current study utilized a series of six multivariate analyses of variance (MANOVAs) and discriminant analyses to determine patterns of psychopathology separating stimulant use from other drug use. Results indicated that women who used stimulants were primarily separated …

Can Clustering Improve Requirements Traceability? A Tracelab-Enabled Study, Brett Taylor Armstrong

Master's Theses

Software permeates every aspect of our modern lives. In many applications, such in the software for airplane flight controls, or nuclear power control systems software failures can have catastrophic consequences. As we place so much trust in software, how can we know if it is trustworthy? Through software assurance, we can attempt to quantify just that.

Building complex, high assurance software is no simple task. The difficult information landscape of a software engineering project can make verification and validation, the process by which the assurance of a software is assessed, very difficult. In order to manage the inevitable information overload …

Variations Of Vibrio Populations In Pacific White Shrimp, Litopenaeus Vannamei, Aquaculture Raceways, Tracy Rene Berutti

Master's Theses

Reducing incidence of vibrioses in intensive aquaculture systems is essential to maintaining yields. This study performed real-time qPCR (quantitative polymerase chain reaction) using primers targeting 16s rDNA sequences for total bacteria, the Vibrio genus, and Vibrio parahaemolyticus in aquaculture tanks over the growing season. Total DNA concentrations in each sample were measured with a NanoDrop 2000 Spectrophotometer (Thermo Scientific, Inc. USA). These data were compared to two levels of bio-floc solids removal in addition to physical and chemical tank parameters such as temperature, ammonia, nitrite, nitrate and phosphate. The total bacteria gene copy abundances were higher (p = 0.0081) …

The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris

Master's Theses

Short-term (3-7 days), high doses of creatine (20g/d) and/or sodium bicarbonate (0.5g/kg body weight) supplementation increase exercise performance during short term high intensity activities; however, it remains unclear whether long-term, low doses of these supplements have a positive impact on exercise performance. The purpose of this study was to determine the effects of long-term (8 weeks), low dose creatine supplementation on exercise performance, and whether combining creatine and sodium bicarbonate supplementation has an additive effect. Sixty-three healthy, habitually active, adults (28 M, 35 W; 22+2 years; 23+ 3 BMI) were randomly assigned by sex to one of three supplement groups: …

Seasonal And Diurnal Behavioral Patterns Of Bottlenose Dolphins, Tursiops Truncatus, That Exhibit High Site And Low Site Fidelity To Mississippi Sound, Shauna Marisa Mcbride

Master's Theses

This study examined whether bottlenose dolphins (Tursiops truncatus) exhibit site fidelity to the Mississippi Sound and how the seasonal and diurnal behavioral patterns of dolphins that exhibit high site fidelity to the Mississippi Sound differ from those of dolphins with lower site fidelity. Opportunistic surveys conducted from July 2006 to April 2010 were analyzed. Statistical analyses consisted of nonparametric tests (Spearman's correlation, loglinear models, and Pearson's chi-square) to compare behavioral patterns of high site fidelity, mixed, and low site fidelity groups. Behavioral patterns significantly differed between site fidelity groups across seasons and diurnal periods. Feeding behavior was observed significantly more …

Sensitivity And Species Specificity Of Bisulfite Modification And Pyrosequencing Technology Used To Identify Tissue-Specific Dna Methylation Patterns In Common Biofluids Foudn In Crime Scenes, Sitara Christian Shirwani

Master's Theses

In order to convict the guilty or exonerate the innocent in criminal cases, it is crucial to reconstruct the crime scene and/or determine the nature of the crime. Identifying the different biofluids found at a crime scene can help shed light on these aspects of forensic casework. Recently, DNA methylation has been used as a means of identifying biological materials, as opposed to conventional protein/enzyme based methods. DNA methylation is the addition of a methyl group to the 5' carbon on a cytosine base (C), which is directly followed by a guanine base (G) and are called CpG sites. The …

Narratives By Six Year Old And Nine Year Old Boys: Brute: Institutional, And Non-Institutional Mental Facts, Adam Craig Whipple

Master's Theses

Brute facts, institutional facts, and non-institutional mental facts were studied. The philosophy of constructionism and the theory of intent provided a framework for this research. Intentionality provided the basis for social facts. Brute, institutional, and noninstitutional mental facts were operationally defined. This study analyzed the use of these facts in the narratives of 6-year-old boys and 9-year-old boys. There were a total of 19 participants in this research. This research established brute, institutional, and non-institutional mental facts as appropriate operational categories for studying children's narratives. The 6-year-old boys produced more brute facts than the 9-year-old boys. The 9-year-old boys produced …

Effect Of Antimicrobials And Sodium Replacement Agents On The Survival Of Pathogenic Bacteria In Low Sodium Low-Moisture Part-Skim (Lmps) Mozzarella Cheese, Tiffany M J Taylor

Master's Theses

Recent increases in chronic cardiovascular diseases, such as hypertension, have put pressure on the food industry to reduce sodium levels. Dairy products, though full of vital nutrients, are perceived as being high in sodium. However, the reduction of salt in dairy products could potentially alter the microbial stability, as well as cause unfavorable changes in flavor. In order to reduce the sodium level, while maintaining acceptable flavor and microbial stability, salt replacers and alternative antimicrobial agents may need to be introduced into the food matrix. To identify potential antimicrobials for use in reduced sodium dairy products, this study evaluated the …

Changes In Soil Salinity Levels With The Use Of Recycled Water On Cool Season Vegetables, Dana Cameron Ripley

Master's Theses

Agricultural production in Monterey County, California is a multi-billion dollar industry. Near the coast, seawater intrusion has threatened to degrade the groundwater quality due to over-pumping of the aquifer. The Monterey Regional Water Pollution Control Agency (MRWPCA), in partnership with the Monterey County Water Resources Agency, has provided recycled water since 1998 to over 12,000 acres of prime agricultural farmland in the northern Salinas Valley in an effort to reduce groundwater removal. The dominant soil types in the region are clay loam and clay soils, which are both susceptible to sodium (Na) accumulation and water infiltration problems. Recycled water blended …

Lipid Production By Microalgae Treating Municipal Wastewater, James Edward Kelley

Master's Theses

Microalgae hold much promise as a feedstock in liquid biofuel production. Lipid content of microalgae cells range from 30-80% dry weight of biomass. It is projected that microalgae can produce between 1,000-6,500 gallons/acre/year of oil. Currently, production of industrial algae operates in open raceway ponds that use minimal capital and energy inputs to culture algae. Raceway ponds can also be used to grow microalgae from municipal waste streams. Although high biomass productivity can be achieved in these systems, there remains a large production gap between large volumes of biomass cultivation and high lipid content from microalgae cells. Low lipid content …

Protective Effects Of Sphingomyelin Against Uv Photodamage In Human Keratinocytes, Kathleen De Guzman

Master's Theses

Ultraviolet (UV) radiation has been demonstrated in numerous studies to be a major risk factor for non-melanoma skin cancer development. Despite the emergence of current UV-preventative strategies, such as sunscreens and skin-protective clothing, the incidence of non-melanoma skin cancer has continued to rise. This has encouraged investigations on alternative methods for UV prevention. In particular, bovine milk sphingomyelin has been studied for its potential in protecting human skin against UV photodamage. While the previous studies have suggested that sphingomyelin exhibits UV-protective properties in a human skin equivalent model, the exact mechanisms behind sphingomyelin’s photoprotective effects are yet unknown.

Large-Displacement Lightweight Armor, Eric C. Clough

Master's Theses

Randomly entangled fibers forming loosely bound nonwoven structures are evaluated for use in lightweight armor applications. These materials sacrifice volumetric efficiency in order to realize a reduction in mass versus traditional armor materials, while maintaining equivalent ballistic performance. The primary material characterized, polyester fiberfill, is shown to have improved ballistic performance over control samples of monolithic polyester as well as 1095 steel sheets. The response of fiberfill is investigated at a variety of strain rates, from quasistatic to ballistic, under compression, tension, and shear deformation to elucidate mechanisms at work during ballistic defeat. Fiberfill’s primary mechanisms during loading are fiber …

An Assessment Of Habitat Suitability For Pronghorn Populations Of The Central Valley Region Of California, Virginia Burroughs

Master's Theses

Efforts to reintroduce and maintain populations of pronghorn (Antilocapra americana) to the California Central Valley, specifically the Carrizo Plain National Monument (CPNM) and the Mojave Desert (Antelope Valley) portion of Tejon Ranch, have largely been unsuccessful due to dwindling numbers of translocated animals. The objective of this study was to improve upon previous models for the CPNM using aerial survey data and then apply the model to the Tejon Ranch. Aerial survey data collected from 2000-2010 on the CPNM was used to establish “use” and “non-use” areas in the model. Model variables included vegetation type (forest, shrub, grassland, …
