The Impact Of Breast Cancer Screening On Sleep, Affect, And Immune Functioning, Caitlin Burbridge

Master's Theses

Despite great strides that have been made over the past several decades in terms of diagnosis and treatment, breast cancer remains the most commonly diagnosed cancer in American women and the second leading cause of cancer-related mortality for women in the United States. Although the benefits of early detection of breast cancer have been clearly established, the advantages of screening must also be weighed against a potential corresponding negative psychological impact of screening procedures. The purpose of the present study was to further investigate the impact of breast cancer screening on previously unstudied or understudied aspects of psychological and physiological …

Design Of A Tetracycline Operon Inducible System For The Control Of Vaccinia Virus Replication: Implications For Vaccine Development, Caitlin J. Hagen

Master's Theses

The use of vaccinia virus (VACV) as a vaccine resulted in the eradication of smallpox in 1979. Characteristics that contribute to the effectiveness of VACV as a vaccine and viral vector include its ability to elicit strong, long-lived humoral and cell-mediated immune responses as a live-replicating virus and to accept large inserts of DNA into its genome. However, adverse events associated with its use as the smallpox vaccine have constrained it from being more widely utilized in vaccines and therapies. We propose to improve the safety of VACV as a live-replicating vector by using elements of the tet operon to …

Racial/Ethnic Differences In Possible Selves Of Diverse Adolescents: Implications For Higher Education And Mental Health, Viana Y. Turcios-Cotto

Master's Theses

There are striking disparities in the academic achievement of American youth, with Latino and Black adolescents attaining higher education at vastly lower rates than White adolescents. Though numerous reasons exist for these educational disparities this study examines possible selves as they may relate to educational achievement among Latinos. Specifically, this study investigates: a) racial/ethnic differences in the content and themes of expected possible selves held by young adolescents; b) within group differences among Latino students and their expected possible selves; c) racial/ethnic differences in the relation between higher education possible selves and current mental health adjustment. Written responses reflecting types …

Psychometric Evaluation Of The Timeline Followback For Exercise Among Young Adults, Gregory A. Panza

Testing The Limits Of Hyperspectral Airborne Remote Sensing By Mapping Eelgrass In Elkhorn Slough, Kelley J. Bostrom

Master's Theses

Seagrass ecosystems are a valuable resource, but vulnerable to changing conditions in the coastal ocean. Quantification of seagrass density and distribution from aerial imagery can be applied as a tool in resource management and ecosystem health and stability monitoring. This study investigates analytical methods for mapping eelgrass beds in an optically complex shallow, turbid estuary. Hyperspectral imagery (HSI) of Elkhorn Slough, CA was collected by the Spectroscopic Aerial Mapper with Onboard Navigation (SAMSON) instrument. In-situ data of water column and benthic optical properties and Hydrolight Radiative Transfer model were used to create a spectral library describing the reflectance of Elkhorn …

Bias Correction And Downscaling Of Climate Model Outputs Required For Impact Assessments Of Climate Change In The U.S. Northeast, Kazi F. Ahmed

Master's Theses

Global Climate Models (GCMs) are the typical sources of future climate data required for impact assessments of climate change. However, GCM outputs are related to model-related uncertainties and involve a great deal of biases. Bias correction of model outputs is, therefore, necessary before their use in impact studies. The coarse resolution of GCM simulations is another hindrance to their direct use in fine-scale impact analysis of climate change. Although downscaling of GCM outputs can be performed by dynamical downscaling using Regional Climate Models (RCMs), it requires large computational capacity. When daily climate data from multiple GCMs are required to be …

Barcelona's Public Market System: Bridging The Gap Between The Global And The Local, Larissa Hernandez

Master's Theses

The unique public markets of Barcelona are poised for a thriving future based on their theoretical and empirical grounding and commitment to both global influences as well as the local traditions of trade and consumption. This global/local balance keeps the markets relevant to contemporary consumers and allows them to have a well-rounded experience as they shop. In this paper, I trace the history and previous incarnations of public markets through the Greeks, Romans and Arabs, as well as consider the European situation and its fluctuations over the centuries. I then uncover the debate surrounding globalization, its influence on the food …

Latino/A Lgbtq Migrations, Sarah V. Rodriguez

Master's Theses

Despite Latin America’s lesbian, gay, bisexual, transgender, and queer (LGBTQ) movement’s recent ground-breaking political achievements, wide spread social acceptance of LGBTQ individuals is not evident in every institution, nor in every part of the region. For some, migration to the U.S. is the solution for escaping the strict social constructs of the region. Of the many studies focusing on the LGBTQ individuals, limited research examines the Latino/a segment of the LGBTQ population. The study explores the motivations behind migration as well as the resettlement process of those immigrating to the San Francisco Bay Area from Latin America, focusing on the …

Divergent Discourses: Development Knowledge And Malian Family Planning, Savannah A. Thompson

Master's Theses

I propose that in order to approach corrective recommendations for family planning initiatives an examination of initiative fitness is necessary. Using a Foucauldian approach, this analysis identifies the discursive formations (ideologies) at work in centralized family planning in order to elucidate the female normative model for whom initiative programs are constructed. This norm is contrasted with the lived experiences of Malian women in order to determine if the ideology dictating family planning structures is suitable for the local population. When combined with existing analyses of family planning structures and outcomes, this research helps triangulate family planning in a three-dimensional space, …

Systems At Play: The Construction Of International Systems In Social Impact Games, Jorge Albor

Master's Theses

This thesis explores how game makers conceive of and navigate the intersection between digital systems and real world systems by asking, how can social impact game designers shape procedural rhetoric to effectively address complex real world systems with digital systems? By examining three game case studies, I reach four significant findings regarding player agency, subversive play, design approaches to scale, and game difficulty in regards to systems fluency.

Transforming The Current Thai Political Conflict To A Peaceful Society, Ranatchai Phumcharoen

Master's Theses

This study explores the current Thai political conflict which began in 2005 and continues in 2011. This conflict is different from the nation’s past political conflicts, which were conflicts between people and the government. On the contrary, the current conflict is a conflict between Thais who share different political ideologies. Many scholars have explained causes and effects of the conflict on Thai society. However, currently, only a few scholars have proposed solutions to the conflict. Therefore, this is a challenge in order to investigate the current conflict and figure out sustainable means to transform the conflict and build peace in …

Public Space Planning As A Catalyst For Dweller Initiated Slum Upgrading: Ahmedabad, India, Christopher Bystedt

Master's Theses

This research observes how public space planning can improve slum upgrading projects, focusing on two case study slums in Ahmedabad, India.

The inclusion of formal public space planning into slum upgrading schemes can act as a catalyst for dweller-initiated housing improvements. While municipalities that choose to upgrade their slums are primarily concerned with supplying bare necessity infrastructure—such as water, sewage, and paving—most upgrading schemes ignore the reality that slum communities are complex, integral components of the urbanization process. These settlements deserve and necessitate comprehensive design and planning services which will integrate the community into the larger urban fabric.

Human Rights Education Through Community Radio: The Promotion Of Afro-Colombian Women’S Identity And Rights, Mariana Lopez-Steele

Master's Theses

In 1991, for the first time in history, the Constitution recognized that Colombia is a multiethnic and culturally diverse country. Since then, a number of organizations have emerged to promote and reinforce the right to difference of the Afro-Colombian ethnic community, as well as to claim and defend their rights. This thesis project presents how La Red Nacional de Mujeres Afrocolombianas, Kambirí, a national network of Afro-Colombian women, has used community radio as a tool for imparting Human Rights Education to women through the promotion of their cultural identity. To accomplish this goal, I analyzed the radio programs created by …

Fine-Scale Genetic Structure And Parentage In Urocitellus Beldingi, Marissa R. Lafler

Master's Theses

Urocitellus beldingi (Belding's ground squirrel), previously known as Spermophilus beldingi, is a social, montane rodent that occupies alpine and subalpine meadows in the Sierra Nevadas (Helgen et al. 2009). The Tioga Pass meadow (Mono Co. CA) population has been studied behaviorally and demographically for several decades. Microsatellites were developed for this species and conditions for polymerase chain reaction (PCR) were defined. Nine microsatellite loci amplified adequately and were in Hardy-Weinberg equilibrium, displaying an average heterozygosity of 0.67±0.19. These nine microsatellite loci were analyzed via PCR to elucidate the fine scale genetic structure, offering insight into population health, stochastic events, and …

Polymorphic Variation Of The Dgat1 Gene In Cal Poly Holstein And Jersey Breeds And The Correlation Of Milk Fat Content, And Genetic Values, Andrea M. Laubscher

Master's Theses

The selection of dairy cattle is dictated by improvement of yield and composition of milk. Genotyping tests give breeders the opportunity to use previously unavailable information to increase the frequency of beneficial alleles in their herds. A QTL influencing milk yield and composition is located in the centromeric end of chromosome 14. The polymorphism being analyzed is a K232A substitution (lysine to alanine amino acid change) in exon VII of the diacylglycerol acyl transferase 1 (DGAT1) gene. DGAT1 is a key acyltranferase in triglyceride biosynthesis. DGAT1 encodes an enzyme which catalyzes the final step of mammalian triglyceride synthesis from carbohydrates. …

Simulated Effects Of Varied Landscape-Scale Fuel Treatments On Carbon Dynamics And Fire Behavior In The Klamath Mountains Of California, Kevin J. Osborne

Master's Theses

I utilized forest growth model (FVS-FFE) and fire simulation software (FlamMap, Randig), integrated through GIS software (ArcMap9.3), to quantify the impacts varied landscape-scale fuel treatments have on short-term onsite carbon loss, long-term onsite carbon storage, burn probability, conditional flame length, and mean fire size. Thirteen fuel treatment scenarios were simulated on a 42,000 hectare landscape in northern California: one untreated, three proposed by the US Forest Service, and nine that were spatially-optimized and developed with the Treatment Optimization Model in FlamMap. The nine scenarios developed in FlamMap varied by treatment intensity (10%, 20%, and 30% of the landscape treated) and …

Impact Of Collateral Enlargement On Smooth Muscle Phenotype, Alexander Jerome Bynum

Master's Theses

Peripheral Artery Disease is a very serious disease characterized by an arterial occlusion due to atherosclerotic plaques. In response to an arterial occlusion, arteriogenesis occurs, causing smooth muscle cells to transition from a contractile to synthetic state. Also following an arterial occlusion, functional impairment was seen in the collateral circuit. An immunofluorescence protocol was developed in order to assess the impact of collateral enlargement (arteriogenesis) on smooth muscle phenotype at various time points. Smooth muscle α-actin was used to mark all smooth muscle cells, Ki-67 was used to label proliferating smooth muscle cells, and a fluorescent nuclear stain was used …

Freight Truck Traffic Associated With The Port Of Oakland: A Case Study Of Roadway Impacts, James Hinkamp

Master's Theses

The Port of Oakland (“Port”) is the 5th largest container seaport by volume in the U.S. and the largest in Northern California. Maritime shipping activity at the Port exceeds 2 million import and export twenty-foot equivalent unit (TEU) containers annually. Containers may be full or empty, but nonetheless typically require hinterland shipment and intermodal transfer between maritime and land-based freight distribution systems. The freight trucking mode (“drayage”) handles approximately 80% of all TEU throughput at the Port, thus constituting the majority of landside Port traffic. The Port is also situated adjacent to dense urban development thereby exacting certain external impacts. …

Digitally-Controlled Deep Brain Stimulation Lead Implant System, Matthew Joseph Phillips

Master's Theses

Deep brain stimulation, the treatment of disorders by applying electrical stimulation to brain tissue, is a relatively new field of medicine with great potential to provide cures for neurological disorders. It utilizes a system very similar to a cardiac pacemaker and lead to electrically stimulate brain tissue. This electrical stimulation is programmed to disrupt or mask aberrant brain signals while not impeding the normal function of the brain. The advances in implantable pulse generators designed for deep brain stimulation have been remarkable, and the applications for deep brain stimulation continue to grow including multiple sclerosis (Berk, et al. 2002), severe …

State Super-Maximum Security Policies: An Examination Of Admission Characteristics, Classification Reviews, Mental Health Amenities, And Inmate Privileges, Harry Daniel Butler

Master's Theses

Super-maximum security prisons have flourished within a political environment that endorses tougher criminal sanctions. This punitive evolution has created new problems for correctional agencies attempting to control the “worst of the worst” inmates. Federal courts and researchers have examined the detrimental effects supermax isolation has on inmates’ mental health. This analysis examines forty-two state supermax policies to determine how states admit inmates to supermax custody, the classification review process, the management of inmates with mental illnesses, and the availability of privileges for supermax inmates. Drawing on the concept of the McDonaldization of Justice (Ritzer, 1993), particular attention is given to …

Consequences Of Contact: An Evaluation Of Childhood Health Patterns Using Enamel Hypoplasias Among The Colonial Maya Of Tipu, Amanda R. Harvey

Master's Theses

Located in western Belize, Tipu was occupied from 1541-1704. This Colonial Maya population from a Spanish visita mission church was analyzed to investigate health disturbances associated with European contact. Dental defect called enamel hypoplasias were scored to assess childhood health. Standard methods of scoring (Buikstra and Ubelaker 1994) were employed to assess frequency, severity, and type of episode in the permanent anterior dentition. For analysis, 325 individuals were placed into age groups of subadults (6-17 years), younger adults (18-35 years), and older adults (36-50+ years). The population was also considered for differences by sex and tooth type.

Results showed a …

Two novel thiosemicarbazone ligands, (E)-N-ethyl-2-(4-hydroxy-3-methoxybenzylidene)hydrazinecarbothioamide (N-Ethhymethohcarbthio) and (E)-N-ethyl-2-(1-(thiazol-2-yl)ethylidene)hydrazinecarbothioamide (acetylethTSC), were also prepared. All ligands were characterized by FT IR and electrochemistry. N-Ethhymethohcarbthio were characterized by elemental analysis whereas the reduced Schiff base and K[(Sal-L-tryp)] were characterized by ESI MS. X-ray crystallography was also used to characterize acetylethTSC. The ligands were then reacted with [VO(Sal-L-tryp)(H2O)] (1) (Sal-L-tryp = N-salicylidene-L-tryptophanate) to produce the …

A Study Of The Early American Author Judith Sargent Murray, Her Role In Early American Print Culture And Her Misappropriation By Twentieth-Century Feminism, Robert Allen Fowler

Master's Theses

In 1798, Judith Sargent Murray published a three-volume collection of one hundred miscellaneous essays on topics ranging from social politesse to women’s education to international politics. Her diligence, forethought and manipulation of pseudonyms in the print-hungry post-Revolutionary America create a unique place for her in the history of American letters. However, in the twentieth century, modern feminism has attempted to claim Murray as one of their own, choosing between one and four examples of her work as proof of her forward-looking philosophy, while ignoring significant pieces of those same works as well as much of her oeuvre as a whole …

Motivating Factors Influencing Spectator Attendance At Professional Soccer Events In Brazil, Rafael Andreis

Master's Theses

In Brazil, soccer is regarded so highly that Brazilians often refer to their country as o pais do futebol, or the country of football ("Natal Brazil", 2006). Brazil national soccer teams won five of the nineteen World Cup tournaments, a record that is so far unmatched by any other country. Brazil boasts 102 million soccer fans who attend games in the country's 300 soccer stadiums, which, combined, have more than five million seats (Helal et al., 2006; Fifa.com, 2010). However, while the importance of soccer in Brazil is unquestionable, the monetization of professional soccer in Brazil is currently far from …

Tick Infestations And Their Consequences For Migratory Songbirds During Spring Stopover, Johnny Michael Sellers Jr.

Master's Theses

Migratory birds face a number of challenges during their seasonal movement from tropical/sub-tropical Central and South America to more temperate North America. Maintaining health during migration is of particular concern. This study seeks to understand how haematophageous ectoparasites, such as ticks (Ixodida), impact host body condition as they feed on passerines during migration. We hypothesized that foraging location would impact tick acquisition by migrants and that tick burdens during migration would negatively impact body condition. We surveyed 2,064 birds during spring 2009 and 2010 and found that 2.4% of the surveyed birds were infested with one or more …
