Sex-Specific Distributions Of Leopard Sharks (Triakis Semifasciata) In An Estuarine Environment, Andrea Lynn Launer

Master's Theses

Estuaries are used seasonally by many elasmobranchs for reproduction and as nurseries. The character, location, and availability of elasmobranch habitats in estuaries are often altered by anthropogenic activities and environmental changes. These habitat changes may have different effects on groups within a shark population because sex-specific segregations are common for many elasmobranchs. Leopard Sharks (Triakis semifasciata) are important estuarine predators in California and exhibit sexual segregations. Movements of 13 Leopard Sharks (male n=6, female n=7) tagged with coded acoustic transmitters were monitored from March 14, 2013 to March 9, 2014 using moored receivers in Elkhorn Slough, CA. Movement patterns were …

Lynn Hershman Leeson's Roberta Breitmore And The Art Of Becoming A Woman, Maayan Glaser-Koren

Master's Theses

Throughout the emergence of second-wave feminism in the 1970s, social and political activism inspired female artists to create powerful artworks that critiqued institutional discrimination and supported women's reproductive rights and workplace equality. Feminist artists raised the public's awareness of women's issues by making women the subject of their artwork. In California especially, these creators turned to performance art, often taking their creations to the streets.

This thesis focuses on Lynn Hershman Leeson's performance, Roberta Breitmore (1974-1978), and examines how, through the steps of the performance, the piece's fictitious title character became a living resident of San Francisco. It will explore …

Benthic Macroinvertebrates In Uvas Creek, California, Downstream Of A Reservoir, Carole Ann Foster

Master's Theses

I sampled macroinvertebrates in May, July, and October 2008 in Uvas Creek, a reservoir-regulated stream in south Santa Clara County, California, to assess what factors (including canopy closure, turbidity, and stream flow) downstream of the reservoir were related to food availability for rearing juvenile Steelhead (Oncorhynchus mykiss). I found benthic and drifting macroinvertebrate biomass was considerably greater during most months in the more open-canopied two sites in the downstream reach as compared to the densely shaded, more turbid and silty two sites in the upstream reach. Abundance of important drifting aquatic invertebrates in May (chironomids, simuliids, and baetids) was proportional …

The Abc's Of Being A Fan: An Operant Analysis Of Sports Consumption Behavior, Sean Pradhan

Master's Theses

In the last 30 years, behavioral psychologists have begun to systematically apply the principles of operant theory to the analysis of consumer behavior. Two behavioral approaches that have been successfully employed in consumer behavior analysis are the Behavioral Perspective Model (BPM; Foxall, 1990) and the Behavioral Ecology of Consumption (BEC; Rajala & Hantula, 2000). However, neither of these models has been used to analyze sports consumption behavior. One purpose of the present study was to integrate consumer behavior models with other theoretical approaches to the investigation of sports consumption behavior. A second purpose was to examine the effects of three …

An Assessment Of Artificial Burrows For Burrowing Owls In Northern California, Sandra Menzel

Master's Theses

This study assesses artificial burrows as a management tool for burrowing owls (Athene cunicularia) at two study sites in northern California. The results of t-tests showed that artificial burrows that received annual surface maintenance (n = 113) at one site were occupied for a significantly (p ≤ 0.003) greater number of years than non-maintained (n = 51) artificial burrows at the other site. Maintained burrows were occupied for a mean of 1.90 years (SD = 2.04), compared to a mean of 0.45 years (SD = 0.97) for non-maintained burrows. Even with maintenance, occupancy rates dropped from 31% during the first …

Effects Of Depth, Site, And Season On Phenotypic Variation Of The Geniculate Coralline, Calliarthron Tuberculosum Around The Monterey Peninsula, California, Jasmine Elena Ruvalcaba

Master's Theses

Coralline algae are ubiquitous in near-shore marine environments. In particular, geniculate corallines occur in intertidal and subtidal habitats with abundances typically higher at shallow depths. Due to the high abundance of Calliarthron tuberculosum in Monterey kelp beds, this species was chosen to study effects of depth, site, and season on morphology and physiology. To further understand this pattern, populations from 3 and 10 m depth were sampled at two sites to examine morphometric variables including total length, total width, and number of branch tips as well as, physiological variables including respiration, photosynthetic, and calcification rates. Growth rates were also quantified …

The Role Of Lithology In Glacial Valley Cross-Sectional Shape In Sierra Nevada, California, Kaai Jensen

Master's Theses

It is commonly inferred that alpine glaciers transform fluvial valleys from V to U-shaped. It has been suggested that, under certain circumstances, glaciers are unable to modify V-shaped valleys and that lithology may play an important role in a glacier's ability to effectively erode bedrock. To test this hypothesis, six glaciated valleys with both U and V-shaped cross sections were chosen in the Sierra Nevada (CA) to examine how lithological properties might affect patterns of glacial erosion: Tenaya Canyon, Tuolumne River, Little Yosemite Valley, the San Joaquin River, the north fork of the King River, and Deadman Canyon. Valley profiles …

Developments Of Gigapixel Microscopy, Siyuan Dong

Master's Theses

Fourier ptychographic (FP) imaging is a recently developed technique to get high-resolution high-throughput imaging. FP iteratively stitches together many variably illuminated, low-resolution intensity images in the Fourier space to expand the frequency passband and recover a high-resolution sample image.

There are several latest developments of the Fourier ptychographic imaging scheme. FP scheme can be used as adaptive imaging method. An image-quality metric is defined as a guide star for the optimization process, and system corrections are then performed to maximize such a guide star. The adaptive FP scheme performs system correction by modifying the complex transfer function in the recovery …

Development Of A High Precision Quantum Dot Synthesis Method Utilizing A Microfluidic Reactor And In-Line Fluorescence Flow Cell, William Henry Lafferty

Master's Theses

Quantum dots show great potential for use as spectral converters in solar cells, lighting applications, and biological imaging. These applications require precise control of quantum dot size to maximize performance. The quality, size, and fluorescence of quantum dots depend on parameters that are difficult to control using traditional batch synthesis processes. An alternative, high precision process was developed for the synthesis of cadmium-selenide quantum dots using a microfluidic reactor and fluorescence flow cell. The process required creating separate cadmium and selenium precursors that were then mixed in a nitrogen environment at 17°C. Using an NE-300^® syringe pump, the solution …

The Effects Of Student Involvement In Afterschool Activities On Childhood Obesity, Lauren E. Van Derzee

Master's Theses

Childhood obesity has been a significant health issue in the United States since the 1970s. In an effort to combat this issue, children are encouraged to be physically active and maintain a nutritional diet. Previous sociological literature has analyzed the effects of the family and neighborhood environment in an effort to understand the socioeconomic forces influencing obesity. This study extends this literature by analyzing the effects of how children spend their time in structured, semi-structured, and unstructured afterschool activities. Building upon Pierre Bourdieu’s theory of practice and concept of cultural capital, I argue that afterschool activities present a particular structured …

Dsm-5 Autism Criteria Applied To Toddlers With Dsm-Iv-Tr Autism, Dasal T. Jashar

Master's Theses

The DSM-5 diagnostic criteria for autism spectrum disorders (ASD) include substantial revisions, including the combination of the subcategories (Autistic Disorder, Asperger’s Disorder, and PDD-NOS) into one dimensional category of ASD, combining the social and communication domains into one, and requiring two rather than one repetitive and restrictive behaviors (RRBs). Concerns have been raised about the DSM-5’s sensitivity for very young children, especially since RRBs may not manifest in this age group. In order to address concerns about the sensitivity of the DSM-5 ASD criteria in toddlers, the current study examined if toddlers who received an ASD diagnosis under the DSM-IV-TR …

Gene Expression Analysis Of Bovine Peripheral Blood Mononuclear Cells In Response To Adenovirus-Vectored Foot-And-Mouth Disease Vaccine, Frank Zappulla

Master's Theses

Foot-and-mouth disease virus (FMDV) gives rise to a highly contagious and economically important disease of cloven-hooved animals. Vaccination reduces the economic impact by inducing serotype-specific protection. Recently, a replication-defective adenovirus-vectored foot-and-mouth disease (FMD) subunit vaccine was developed and licensed. Serum virus neutralization (SVN) titer ≥1.5 to FMDV is the best predictor of vaccine-induced protection. However, protection does not always correlate with the presence of neutralizing antibodies. For example, some animals with high SVN titer develop signs of disease, and conversely, some animals with negligible SVN titer are protected. Categorizing cattle on the parameters of seroconversion and protection status yields four …

The Effect Of Cyclophilin A On Vaccinia Virus Replication In Vitro, Kathryn Korhonen

Master's Theses

The host protein cyclophilin A (CypA) has been shown to be necessary for viral replication of several viruses, including human immunodeficiency virus and hepatitis C virus. Previous research done in the Geary laboratory, in collaboration with Pacific Northwest National Laboratory, reported that cyclophilin A remains highly associated with vaccinia virus virions even after successive rounds of purification. The goal of this research is to further investigate how cyclophilin A affects vaccinia virus replication in vitro using primary tissues harvested from CypA (-/-) knockout mice to determine the difference in viral growth kinetics. Results showed different viral growth kinetics in …

Reduction Of Obesity-Associated Oxidative Stress By Low-Fat Yogurt Consumption, Diana M. Dimarco

Master's Theses

Excess macronutrient intake leads to an increase in formation of reactive oxygen species (ROS). This causes an imbalance between ROS generation and the ability of the body to neutralize these radicals, a state known as oxidative stress. Previous research suggests the ability of dairy products to attenuate the postprandial response, which may reduce ROS formation. Therefore, this study aimed to elucidate the impact of low-fat yogurt consumption on fasting and postprandial oxidative stress in obese women.

We hypothesized that co-consumption of low-fat yogurt and a high-calorie, high-fat meal would reduce postprandial elevations in oxidative stress in obese women. To test …

An Insight To Psychological Health, Health Behaviors, And Bodyweight Among Correctional Employees, Christina Mignano

Master's Theses

Background: Correctional employees present a poor physical and mental health profile including high rates of overweight/obesity, poor health behaviors (diet, exercise, and sleep quality), high stress levels, and poor psychological health (e.g. high rates of depression, suicide, and divorce). Worse, correctional employees deny their stress and negative emotions as their occupational culture discourages expressing negative characteristics that would make one appear weak and deters seeking psychiatric help. Correctional employees are in need of effective health promotion efforts that address determinants of employee health with an all-inclusive view (mental/emotional/behavioral). Purpose: The purpose of this study was to assess if stress and/or …

Manipulation Of Larval And Winter Habitat Reveals Potential Effects Of Urbanization And Climate Change On Wood Frogs In Connecticut, Jason H. O'Connor

Master's Theses

Human activity can result in both local and global changes in the environment which in turn can affect other organisms and may result in population declines and loss of biodiversity. At the local scale, human activity often causes changes in habitat quality. For example, development and agriculture increase water turbidity which can influence wetland communities. At a global scale, carbon emissions are altering Earth’s climate, leading to increasing air temperatures. Using Wood Frogs, Lithobates sylvaticus, a wide-ranging, pond breeding amphibian, I sought to determine how sediment input affects larval amphibians and to assess how predicted loss of snow cover …

Conservation Of Bridle Shiner (Notropis Bifrenatus) In Connecticut: Issues In Detecting An Elusive Species, Kasey C. Pregler

Master's Theses

Bridle Shiner (Notropis bifrenatus) is apparently declining over most of its range and is currently listed as a species of concern in Connecticut. Using an occupancy modeling framework in program PRESENCE, my study compared seining and electrofishing backpack unit detection probabilities of Bridle Shiner. This research indicated the apparent decline of Bridle Shiner in the state was in part due to changes in sampling gear used for statewide surveys. Seining used 50 years ago was demonstrably more effective at capturing Bridle Shiner than the currently favored and more frequently used electrofishing gear. In light of this recent finding, …

Geomicrobial Investigation Of Thrombolites In Green Lake, New York And Highborne Cay, Bahamas, Molly Patterson

Master's Theses

Thrombolites are non-laminated, clotted microbialites that form by the lithification of microbial communities through the trapping and binding of sediment and mineral precipitation. This precipitation (microbially-induced organomineralization) is controlled by both intrinsic (microbial; e.g. microbial metabolisms) and extrinsic (environmental; e.g. temperature) factors, which dictate the carbonate saturation index and ultimately the precipitation of carbonate minerals within the microbialite structure (i.e. EPS matrix). Thrombolites date back in the rock record to the early Paleoproterozoic (ca. 1.9 Ga) and are currently forming around the world in various climates and under a range of environmental conditions. This study compares two markedly different modern …

Avoided Water Cost Of Electricity Generation For Solar Pv And Wind Technologies In Southern California, Matthew Cohen

Master's Theses

The objective of this thesis is to provide a foundation for evaluating the water costs associated with electricity production to calculate the avoided water cost of energy for solar PV and wind technologies relative to coal, natural gas, nuclear, geothermal, concentrated solar thermal, and biomass. Water consumption is estimated for energy production (fuel extraction and preparation) and electricity generation (power plant operation) using the best available information from published articles. The quantity of water consumed for electricity production is monetized for a Southern California case study based on the water rates of Metropolitan Water District of Southern California (MET), which …

Effects Of Water Parameters On Container Mosquito (Diptera: Culicidae) Oviposition And Performance, Stephanie Sue Schelble

Master's Theses

Water body parameters have a considerable effect on the communities that develop within them. In small container habitats like tires, the depth, surface area, and volume effect the development and success of the mosquito communities. This study investigated the choices of the adult female mosquitoes, Aedes albopictus and Culex quinquefasciatus, between different depths and surface areas. In addition, larval performance was determined under differing depth and larvae densities. Oviposition studies showed that Ae. albopictus had a preference for deeper habitats (χ²= 14.2902, p= 0.0139) but did not prefer any surface areas (χ²= 7.2321, p= 0.0649) though …

Characterizing Populations Of Non-Coding Rnas In Karenia Brevis At Different Times Of The Diel Cycle, Scott Boyd Anglin

Master's Theses

Karenia brevis is a mixotrophic, marine dinoflagellate found in the Gulf of Mexico that generates periodic, if not annual, harmful algal blooms (also known as “red tides”) in certain coastal areas. In an effort to better understand the biology of this organism, a functional genomics project has been initiated. As part of that project, it has been determined that a significant number of natural antisense transcripts (NATs) as well as double-stranded RNA (dsRNA) molecules exist within the transcriptome of K. brevis. I hypothesize that the non-coding NATs, similar to microRNAs (miRNAs) in other organisms play a role in regulating …

Identification And Characterization Of Msab Gene Involved In Biofilm Formation And Virulence In Staphylococcus Aureus, Amelsaad Elbarasi

Master's Theses

Staphylococcus aureus is an important human pathogen that causes a wide variety of life-threatening infections ranging from minor skin and oral infections to severe infections, such as bacteremia, pneumonia, osteomyelitis, or endocarditis due to the presence and secretion of a large number of virulence factors that are controlled by global virulence regulators in complex networks. Furthermore, S. aureus infections have become a threat to public health because of their high potential to form biofilm, and their ability to resist a wide range of antibiotics has exacerbated further. Therefore, understanding the regulatory networks and developing a drug targeting these networks has …

Selling Tradition: Impression Management And Draft Animal Agriculture Of A Mississippi Farmstead, Matthew Corbin Lance

Master's Theses

This thesis is a case study of a family of farmers in Mississippi’s Piney Woods who use horse-drawn equipment to grow crops. This practice is notable in the context of a larger agricultural system that prioritizes mechanization (particularly the use of tractors). The production style and their use of local direct selling via farmers markets allowed them to thrive economically because they were able to tap into a niche market of consumers desiring an alternative to the modern, conventional agricultural system.

Other literature on Alternative Food Networks (AFN) discusses the issues of alterity and appropriation—that is, whether AFN ventures are …

Investigating Hemodynamic Responses To Electrical Neurostimulation, Sean Youra

Master's Theses

Since the 1900s, the number of deaths attributable to cardiovascular disease has steadily risen. With the advent of antihypertensive drugs and non-invasive surgical procedures, such as intravascular stenting, these numbers have begun to level off. Despite this trend, the number of patients diagnosed with some form of cardiovascular disease has only increased. By 2030, prevalence of coronary heart disease is expected to increase approximately by 18% in the United States. By 2050, prevalence of peripheral arterial occlusive disease is expected to increase approximately by 98% in the U.S. No single drug or surgical intervention offers a complete solution to these …

A Rubric For Electrochemical Testing Of Metallic Biomaterials, Frederick G. De La Fuente

Master's Theses

Corrosion is a major factor for the failure of metallic medical implants. Testing a metal’s suseptability to corrosion prior to implantation is key to a successful implantation. Electrochemical processes were used in this study to evaluate the characteristics of corrosion of both AISI 316 stainless steel and titanium alloy Ti6Al4V, welded and non-welded. Linear, potentiodynamic, and cyclic polarization curves were produced by the PARC 2273 potentiostat showing the corrosion tendencies of the metals in four unique solutions 3.5% NaCl, 0.35% NaCl, phosphate buffered saline solution (PBS), and Butterfield phosphate buffered solution (BPS). The concentration of chloride ions in solutions affected …
