Gender, Sport & Nationalism: The Cases Of Canada And India, Courtney Glass

USF Tampa Graduate Theses and Dissertations

This research seeks to explore the gendered nature of nationalisms and the ways that they can be challenged and perhaps transformed through the participation of women in sport at the national level. Nationalism is part of the public sphere, while women have historically been relegated to the private sphere. However, many scholars argue that women do in fact taken part in nation building primarily as biological reproducers of the nation. This has led scholars to conclude that nationalism is indeed gendered. Sport has traditionally been a masculine domain where conceptions of hegemonic masculinity as well as the nation are developed …

The Modulation By Anthrax Toxins Of Dendritic Cell Activation, Ping-Jen Chou

USF Tampa Graduate Theses and Dissertations

Bacillus anthracis produces lethal toxin (LT) and edema toxin (ET) and they suppress the function of LPS-stimulated dendritic cells (DC). Because DCs respond differently to various microbial stimuli, we compared toxin effects in bone marrow DCs stimulated with either LPS or Legionella pneumophila (Lp). DCs were enriched with GM-CSF for 9 days, purified by positive selection, and treated with toxins for 6h; cells were then stimulated with either LPS or Lp-infection for 24h. DC cytokine production and maturation marker expression varied depending upon cell stimulus and the mouse strain used. LT but not ET was more toxic for cells from …

The Social Context Of Cervical Cancer Knowledge And Prevention Among Haitian Immigrant Women, Janelle Marie Menard

USF Tampa Graduate Theses and Dissertations

Cervical cancer is the primary cause of cancer deaths among Haitian women; however, the social context of cervical cancer among Haitian immigrant women has not been systematically examined. The ways in which women assign meaning to this disease, understand its causality and situate it within the broader context of gynecological health are poorly understood. Further, Haitian immigrant women's perceptions of disease risk, including knowledge and understanding about Human Papillomavirus (HPV), the primary etiologic factor in cervical cancer, have not been explored. Few studies have assessed health behaviors, including culturally mediated feminine hygiene practices, among Haitian immigrant women, which may negatively …

Public Opinion And The Introduction Of Congressional Environmental Legislation, 1973-2002, Hugh Eugene Jarvis

USF Tampa Graduate Theses and Dissertations

This study examines the relationship between public opinion about the environment and the introduction of congressional legislation on environmental issues. Using public opinion data gathered by the General Social Survey from 1977 to 2002, this work examines correlations between how the public views the environment in each and the number of bills introduced in the U.S. House and Senate addressing environmental issues. The findings indicate that there is a correlation between overall concern felt in the public and congressional action on certain aspects of environmental protection. The results also highlight the potentially disturbing finding that the race and economic class …

The Role Of Pharmacists And Emergency Contraception: An Assessment Of Pharmacy School Curricula In The U.S. And The Knowledge, Attitudes, And Dispensing Practices Of Florida Pharmacists., Alice R. Richman

USF Tampa Graduate Theses and Dissertations

Emergency contraception is a safe and effective form of contraception that is 75%-89% effective in preventing pregnancies within 120 hours of unprotected intercourse. Emergency contraception is a type of hormonal contraception, containing high doses of estrogen and progestin (ethinyl estradiol plus levonorgestrel) or progestin only (levonorgestrel). Wider access to emergency contraception has the potential to decrease the number of unintended pregnancies and abortions in the U.S. The Food and Drug Administration (FDA) has previously denied any over-the-counter (OTC) access to emergency contraception and only recently approved it for OTC status for women 18 years old and over; therefore, pharmacists continue …

Three-Dimensional Microscopy By Laser Scanning And Multi-Wavelength Digital Holography, Alexander Khmaladze

USF Tampa Graduate Theses and Dissertations

This dissertation presents techniques of three-dimensional microscopy. First, an economical method of microscopic image formation that employs a raster-scanning laser beam focused on a sample, while non-imaging detector receives the scattered light is presented. The images produced by this method are analogous to the scanning electron microscopy with visible effects of shadowing and reflection. Compared to a conventional wide-field imaging system, the system allows for a greater flexibility, as the variety of optical detectors, such as PMT and position-sensitive quadrant photodiode can be used to acquire images. The system demonstrates a simple, low-cost method of achieving the resolution on the …

The Effect Of Hydrogen On The Optical, Structural Properties And The Crystallization Of Gete2 Thin Films Prepared By Rf Magnetron Sputtering, Ke Cao

USF Tampa Graduate Theses and Dissertations

Thin films of GeTe₂ were deposited on glass substrates using RF magnetron sputtering with various hydrogen flow rates in the growth chamber. Transmission data of deposited films were taken and used to determine optical constants: refractive index (n), extinction coefficient (κ), and absorption coefficient (α)) and the energies: E₀₄, E₀₃, Tauc band gap E[subscript]Tauc and Urbach energy E[subscript]U. An increase of these energies was observed with increasing hydrogen flow rate. This increase is interpreted on the basis of the density of state model proposed by Mott and Davis. An increase of network disorder due to the inclusion of hydrogen into …

Flavonoids As Modulators Of Amyloid Precursor Protein Metabolism And Alzheimer Disease Pathology, Kavon Rezai-Zadeh

USF Tampa Graduate Theses and Dissertations

Alzheimer disease (AD) is a progressive neurodegenerative disorder pathologically characterized by deposition of ß-amyloid (Aß) peptides as plaques in the brain. Central to this AD pathology is mismetabolism of the amyloid precursor protein (APP). Recent studies suggest that flavonoids, a class of secondary plant metabolites, may be useful for the prevention and treatment of a variety of neurodegenerative diseases. The studies detailed herein, investigate the ability of two such classes of flavonoids, green tea derived catechins and 5,7-dihydroxyflavones, to modulate APP metabolism in "Swedish" mutant APP (APP_sw) models of AD. Studies showed that green tea derived (-)-epigallocatechin-3-gallate (EGCG) …

Eastern Equine Encephalitis virus has a human mortality rate of 30% of those cases diagnosed, while 30% of those surviving infection remain with neurological sequelae for life (CDC.gov, 2007).

The use of sentinel chickens for surveillance of arboviruses that are known to use birds as a reservoir host, such as St. Louis Encephalitis (SLE), West Nile (WN) virus, Eastern Equine Encephalitis (EEE) and Highlands J (HJ) virus, in Florida began with the Sentinel Chicken Arboviral Surveillance Network in 1978 (Day and Stark, 1996). This network enables the activation of an early warning system for citizens, as well as, county epidemiologists …

Multilocus Virulence Typing Of Clinical And Environmental Vibrio Vulnificus Isolates, Katrina V. Gordon

USF Tampa Graduate Theses and Dissertations

The bacterium Vibrio vulnificus is an autochthonous inhabitant of estuarine waters and also found in shellfish such as oysters. It is a human pathogen of importance in the seafood industry, and can also infect recreational water users. Currently, recognized methods of detection rely upon isolation of pure cultures which requires at least 24 hours. To reduce the time needed for identification of the pathogen and simultaneously ascertain the virulence potential of the strains present, real-time PCR assays and sample processing procedures were developed (Chapter 1). These assays discriminate between type A (environmental, generally lower virulence) and type B (clinical, higher …

The Acceptability Of Treatments For Adolescent Depression To A Multi-Ethnic Sample Of Girls, Nicole Caporino

USF Tampa Graduate Theses and Dissertations

An efficacious treatment is diminished in value if clients will not seek it out and adhere to it (Kazdin, 1978). Thus, the acceptability of a treatment to consumers is an important indicator of the quality/effectiveness of the treatment (APA, 2002). The purpose of this study was to examine acceptability of treatments for depression to adolescent females and to explore factors that might be associated with acceptability. Sixty-seven high school students (36 Hispanic and 31 non-Hispanic White) were recruited from communities in New Jersey and Florida, and interviewed by telephone. Participants were presented with a vignette describing a depressed adolescent and …

Microarray Analysis Of Streptococcus Mutans And Actinomyces Viscosus In Homologous And Heterologous Cultures, Steven Andrew Horton

USF Tampa Graduate Theses and Dissertations

The oral pathogen Streptococcus mutans is a known etiological agent for dental root decay and coronal caries. It has been hypothesized, but not yet proven, that S. mutans expression of virulence genes in dental plaque may be influenced by its interaction with co-aggregating partners, notably Fusobacterium nucleatum and Actinomyces viscosus. Investigation of the suitability of mixed cultures of S. mutans with F. nucleatum versus S. mutans with A. viscosus proved that A. viscosus was a better target in the present laboratory setting. Furthermore, A. viscosus, a causative agent of mandible osteomyelitis and endocarditis, has been shown to have …

The Development And Validation Of The Perceived Workplace Civility Climate Scale, Raymond Charles Ottinot

USF Tampa Graduate Theses and Dissertations

The goal of this study was to extend the concept of safety climate into the aggression research domain. In order to address this goal I developed and validated the perceived workplace civility climate scale (PWCC), which assesses the extent to which employees perceive the importance an organization places upon managing and preventing acts of incivility and verbally aggressive actions in the workplace. The factor analytic results produced three factors: (1) Intolerance, (2) Response, and (3) Policies and Procedures. All dimensions demonstrated adequate reliability and correlated significantly to hypothesized stressors and strains. Lastly, correlation results (i.e., convergence) between self- and peer …

The Channel For Gay America? A Cultural Criticism Of The Logo Channel’S Commercial Success On American Cable Television, Michael Johnson Jr.

USF Tampa Graduate Theses and Dissertations

Logo currently holds a self-described monopoly as the "Gay Channel for America." Logo stands alone as the single most concentrated national-level vehicle of LGBT (Lesbian, Gay, Bisexual and Transgendered) visibility in the post millennial television era. The Logo Channel has reaped financial rewards from its strategy as a business entity, as LGBT American television viewers embraced its presence as a signifier to America that gays and lesbians have finally "made it".

First, any claim to a monopoly deserves critical attention for its place in mainstream television, for its business practices, and for the power it holds in representing and targeting …

Kandinsky’S Dissonance And A Schoenbergian View Of Composition Vi, Shannon M. Annis

USF Tampa Graduate Theses and Dissertations

In this study, I clarify the relationship between Wassily Kandinsky's move towards abstraction in painting and his encounters with the music and theory of Arnold Schoenberg. Prior studies have concentrated on the similarities in their theories, but I examine Kandinsky [sic] idiosyncratic understanding of Schoenbergian concepts and the evolution of his engagement with music theory over the period of 1909 to 1914. I identify dissonance as the aspect of Schoenberg's music and theory that Kandinsky found most relevant to his own developing compositional theory for abstract painting. In music, dissonance is commonly considered to be combinations of tones that sound …

Pandemic Vibrio Parahaemolyticus: Defining Strains Using Molecular Typing And A Growth Advantage At Lower Temperatures, Carisa Renee Davis

USF Tampa Graduate Theses and Dissertations

Vibrio parahaemolyticus is a leading cause of seafood-borne illness with a newly emerged pandemic strain. Previous studies compared the pandemic and non-pandemic strains to understand the evolution of the pandemic strain but no definitive explanation for its emergence has been discovered. This study investigated the molecular characteristics of the pandemic strain and growth characteristics at different temperatures. The hypothesis tested was that pandemic strains of V. parahaemolyticus have modifications to their proteome that give a selective advantage over the other V. parahaemolyticus strains at temperatures normally encountered in the environment. Molecular typing techniques; automated ribotyping, pandemic specific PCR and multilocus …

Eutrophication Trend Of Lakes In The Tampa Bay Watershed And The Role Of Submerged Aquatic Vegetation In Buffering Lake Water Phosphorus Concentration, Max Jacobo Moreno Madriñan

USF Tampa Graduate Theses and Dissertations

Twentieth century human settlement within the Tampa Bay watershed was linked to a dramatic mid-century decline in bay water quality and loss of seagrass acreage. Decades of direct and indirect nutrient discharges to the bay from phosphorus mining, fertilizer manufacturing, and wastewater treatment, as examples, impaired the estuary. In the past twenty years, regional stakeholders have worked to improve the bay water quality by reducing point and non-point source nutrient loading to the bay.

Lakes within the Tampa Bay watershed may play an important role in attenuating the flow of nutrients into the bay. This study hypothesized that between 1990 …

Disgusted By Food: Explanatory Models Of Anorexia Among Young Taiwanese Adults, Donald E. Mclawhorn Jr.

USF Tampa Graduate Theses and Dissertations

Anorexia as a nosological category has developed in a western context and is now being applied to people around the world. In order for researchers to know they are asking the right questions about AN as knowledge expands, it is important to understand what meanings Anorexia carries and how those meanings manifest locally. The present study to aid in that understanding by employing a mixed methods (survey and in-depth interviewing) research approach in answering the following question: In what ways are Taiwanese students' explanatory models of anorexia nervosa (AN) congruent with or different from professional understandings derived from the western …

The Role Of Lifestyle Factors In Cognitive Aging And Dementia, Tiffany F. Hughes

USF Tampa Graduate Theses and Dissertations

It is widely accepted that cognitive abilities decline with normal aging. At the same time it is also recognized that there is variability in the magnitude and rate of decline among aging individuals. A similar phenomenon exists for dementia, where individuals with similar neuropathologic burden present with varying degrees of cognitive impairment. Of importance is determining what factors account for this variability, and whether individuals can modify these factors in order to preserve their cognitive abilities with aging or delay the onset of dementia.

The purpose of this dissertation was to examine three potentially modifiable lifestyle factors' association with age-related …

State Dominance And Political Corruption: Testing The Efficacy Of An Alternate Configuration Of Institutional-Anomie Theory Cross-Nationally, Carol L. S. Trent

USF Tampa Graduate Theses and Dissertations

Extant assessments of Messner and Rosenfeld's institutional-anomie theory (1994) have generally supported the thesis that, in social collectives where the economy dominates, non-economic institutions (i.e. the family, education, polity) are rendered feeble, unable to exert their normative controls. The cultural values of these societies place primacy on "making it" (monetary success), while at the same time placing a much weaker emphasis on the licit means of achieving these goals. The resultant state is one of anomie, conducive to crime. Messner and Rosenfeld have extended their argument stating that it is not economic dominance per se that contributes to high crime …

Communication Systems And Hiv/Aids Sexual Decision Making In Older Adolescent And Young Adult Females, Rasheeta D. Chandler Ms, Arnp, Fnp-Bc

USF Tampa Graduate Theses and Dissertations

Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) is a national priority for several reasons including its endemic/pandemic status and economic demand. Adolescents 15 to 24 years old who are sexually active acquire nearly half of all new Sexually Transmitted Infections (STIs). Recent findings from the Centers of Disease Control (CDC) have documented increased teen birth rates, escalating births to unwed mothers, and STIs ascribed to one in four adolescent females, are reasons to enhance effective prevention efforts.

The specific aim of the study, based on Bandura's social cognitive theory, was to test associations among communication system methods and …
