USF Tampa Graduate Theses and Dissertations

The colorectal cancer (CRC) incidence in Ashkenazi Jews has been found to be highest of any ethnic group in the world (Feldman, 2001). It is currently unclear how culture and religion influence health behaviors of U.S. Ashkenazi Jews, as well as what other socio-cultural factors influence AJ women's attitudes towards CRC risk and screening practices. This study aimed at exploring and describing the cultural and religious influences on health behaviors and beliefs related to CRC in Ashkenazi Jewish women. Research participants included seven key informants (rabbis) and forty-two Ashkenazi Jewish women ages 50 and up. Methods included in-depth, qualitative interviews …

Genetic Algorithm Based Design And Optimization Of Vlsi Asics And Reconfigurable Hardware, Pradeep Ruben Fernando

USF Tampa Graduate Theses and Dissertations

Rapid advances in integration technology have tremendously increased the design complexity of very large scale integrated (VLSI) circuits, necessitating robust optimization techniques in many stages of VLSI design. A genetic algorithm (GA) is a stochastic optimization technique that uses principles derived from the evolutionary process in nature. In this work, genetic algorithms are used to alleviate the hardware design process of VLSI application specific integrated circuits (ASICs) and reconfigurable hardware.

VLSI ASIC design suffers from high design complexity and a large number of optimization objectives requiring hierarchical design approaches and multi-objective optimization techniques. The floorplanning stage of the design cycle …

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 …

Artist Colonies In Europe, The United States, And Florida, Jennifer L. Aldrich

USF Tampa Graduate Theses and Dissertations

During the nineteenth century, an artistic trend spread across Europe. As urban centers housed the majority of professional artists, individuals and groups relocated to remote, bucolic areas to form art colonies. Artist colonies are typically defined as a group of artists, generally painters, writers, and composers who worked and lived as a community for a certain period of time¹. Artists left their city lifestyles as a response to urbanization and industrialization. In other words, the movement encouraged reform of social, environmental, and economic conditions to prevent the decline of true artisanship. The artistic response personified an underlying utopian …

Two Essays On Financial Condition Of Firms, Sanjay Kudrimoti

USF Tampa Graduate Theses and Dissertations

This dissertation includes two related chapters that analyze financial condition of firms. In the first chapter, I examine the relationship between the firms' level of cash holdings and governance. The findings show that higher levels of cash holdings are significantly related to strong governance. The results also show that firms with strong governance hold asymmetrically higher levels of cash than firms with weak governance when they have high growth opportunities. Furthermore, I also test the impact of financial constraint status of the firm on the level of cash holdings for both good and poorly governed firms separately. The results suggest …

A Molecular-Dynamics Study Of The Frictional Anisotropy On The 2-Fold Surface Of A D-Alnico Quasicrystalline Approximant, Heather Mcrae Harper

USF Tampa Graduate Theses and Dissertations

In 2005, Park et al. demonstrated that the 2-fold surface of a d-AlNiCo quasicrystal exhibits an 8-fold frictional anisotropy, as measured by atomic-force microscopy, between the periodic and aperiodic directions [40, 41]. It has been well known that quasicrystals exhibit lower friction than their crystalline counterparts [38, 18, 51, 30, 12, 54]; however, the discovery of the frictional anisotropy allows for a unique opportunity to study the effect of periodicity on friction when chemical composition, oxidation, and wear are no longer variables.

The work presented herein is focused on obtaining an understanding of the mechanisms of friction and the …

This study investigated the effects of Dynamic Assessment (DA) training on the mediational strategies of experienced teachers of French as a foreign language. Moreover the strategies that mediators used for students at different levels of language experience were investigated. Last the ways in which mediators manifested mediational sensitivity, reciprocity and management was examined.

Four mediators underwent DA training that exposed them to the theoretical underpinnings of DA as well as sound DA procedures. To determine the effect of this training, the way in which the mediators conducted their mediation was compared from pre-DA training to post-DA training. Three of these …

The Relationship Between Childhood And Adolescent Family Environment And Adult Psychological Functioning In Females Who Experienced Childhood Sexual Abuse, Ross Krawczyk

USF Tampa Graduate Theses and Dissertations

Research has shown childhood sexual abuse (CSA) to be related to many negative outcomes in adulthood including psychopathology. Findings in this area, however, are very inconsistent, with the relationship between CSA and adult outcomes varying greatly across studies. This relationship is further complicated by the co-occurrence with CSA of other risk factors in childhood. The present study examines the prediction of adult psychopathology, measured by the Brief Symptom Inventory (BSI; Derogatis, 1982), made by CSA, measured by the Early Sexual Experiences Survey (ESE; Bartoi & Kinder, 1998), childhood SES (Hollingshead, 1975), parental bonding, as measured by the Parental Bonding Instrument …

Statistical Profile Generation Of Real-Time Uav-Based Traffic Data, Anuj Puri

USF Tampa Graduate Theses and Dissertations

Small unmanned vehicles are used to provide the eye-in-the-sky alternative to monitoring and regulating traffic dynamically. Spatial-temporal visual data are collected in real-time and they are used to generate traffic-related statistical profiles, serving as inputs to traffic simulation models. Generated profiles, which are continuously updated, are used to calibrate traffic model parameters, to obtain more accurate and reliable simulation models, and for model modifications. This method overcomes limitations of existing traffic simulation models, which suffer from outdated data, poorly calibrated parameters, questionable accuracy and poor predictions of traffic patterns.

A Longitudinal Study: The Impact Of A Comprehensive Emergency Management System On Disaster Response In The Commonwealth Of The Bahamas, Erin P. Hughey

USF Tampa Graduate Theses and Dissertations

Global trends show increasing losses from disasters as the number of people at risk grows by 70 to 80 million per year (United Nations, 2004). Although the frequency of natural disasters may be constant the human interaction with the given hazard has shifted through changes in development practices, environmental protection as well as the distribution of population and wealth. In an effort to combat the negative social, economic, and environmental impacts of hazards, strategies for identifying vulnerable populations and implementing mitigation measures is a high priority in hazards research. However despite our best efforts disasters have and will continue to …

Relationship Of Anger Trait And Anger Expression To C-Reactive Protein In Post-Menopausal Women, Rosalyn Gross

USF Tampa Graduate Theses and Dissertations

Coronary heart disease is the leading cause of death in American women, accounting for one in six deaths in 2004. One third of women over the age of forty will develop coronary heart disease in their lifetime. The role of chronic and excessive inflammation and risk factors, such as smoking and high cholesterol, are now well-established factors contributing to coronary heart disease pathology. A knowledge gap exists in that little is known about the mechanisms by which psychosocial factors, such as anger, may be associated with pro-inflammatory processes that contribute to cardiovascular morbidity and mortality in women. The purpose of …

Evaluating The Efficacy Of The Developing Algebraic Literacy Model: Preparing Special Educators To Implement Effective Mathematics Practices, Sharon N. E. Ray

USF Tampa Graduate Theses and Dissertations

For students with learning disabilities, positive academic achievement outcomes are a chief area of concern for educators across the country. This achievement emphasis has become particularly important over the last several years because of the No Child Left Behind legislation. The content area of mathematics, especially in the higher order thinking arena of algebra, has been of particular concern for student progress. While most educational research in algebra has been targeted towards remedial efforts at the high school level, early intervention in the foundational skills of algebraic thinking at the elementary level needs consideration for students who would benefit from …

Active And Passive Microwave Radiometry For Transcutaneous Measurements Of Temperature And Oxygen Saturation, Thomas A. Ricard

USF Tampa Graduate Theses and Dissertations

In this work we explore two novel uses of microwave technology in biomedical applications. Introductory material on the electrical properties of biological tissues is presented to form the groundwork for the basic theory behind both techniques.

First, we develop a technique that uses 60 GHz signals to detect changes in blood oxidation levels. Several atmospheric propagation models are adapted to predict oxygen resonance spectra near this frequency. We are able to predict and observe the changes in these levels as the blood ages up to 48 hours. Identical testing procedures performed using arterial blood gas (ABG) calibration samples with controlled …

Factors Affecting Message Intelligibility Of Cued Speech Transliterators, Katherine Pelley

USF Tampa Graduate Theses and Dissertations

While a majority of deaf students mainstreamed in public schools rely on interpreters, little research has investigated interpreter skills and no research to date has focused on interpreter intelligibility (Kluwin & Stewart, 2001). This thesis is the second in a series of experiments designed to quantify the contribution of various factors affecting the intelligibility of interpreters (transliterators) who use English-based communication modes. In the first experiment, 12 Cued Speech transliterators were asked to transliterate an audio lecture. Two aspects of these transliterated performances were then analyzed: 1) accuracy, as measured as the percent-correct cues produced, and 2) lag time, the …

Regards Sur L’Être Et Le Paraitre Dans Trois Portraits Du Xviie Siècle, Martine J. Landis

USF Tampa Graduate Theses and Dissertations

Introduced in French Salons as a parlor game, the literary portrait appears in mid Seventeenth-Century. It is similar to the literary portraits inserted in Roman à clé but it does not hide the identity of the subject behind a pseudonym, it depicts the individual as is. In a self-portrait subjects look at, observe, evaluate then describe themselves. They offer themselves to the gaze of others and propose a true reading of what they are. The self-portrait attempts to harmonize the appearance and the inner being, to render visible the essence of the person. However, in the Seventeenth Century, people reinvent …

Reporting was manipulated at two levels: periodic and continuous. Assurance was manipulated at two levels: no assurance and with assurance. In addition, a base level condition was included. The experiment was designed to collect data regarding both the investors' performance and their perceptions. Period one of the experiment consisted of the base level condition for all participants. Independent variable manipulation was implemented in period two, using …

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 …

Toward The Synthesis Of Designed Metal-Organic Materials, Jacilynn A. Brant

USF Tampa Graduate Theses and Dissertations

Metal-Organic Materials (MOMs) are an emerging class of crystalline solids that offer the potential for utilitarian design, as one of the greatest scientific challenges is to design functional materials with foreordained properties and eventually synthesize custom designed compounds for projected applications. Polytopic organic ligands with accessible heteroatom donor groups coordinate to single-metal ions and/or metal clusters to generate networks of various dimensionality. Advancements in synthesis of solid-state materials have greatly impacted many areas of research, including, but not limited to, communication, computing, chemical manufacturing, and transportation.

Design approaches based on building blocks provide a means to conquer the challenge of …

Structural Diversity In Metal-Organic Materials, Gregory J. Mcmanus

USF Tampa Graduate Theses and Dissertations

The interest in metal-organic materials namely, coordination polymers and metal-organic frameworks has risen dramatically over the past few years. To a certain extent this interest is a consequence of the realization chemists have discovered how to play a form of molecular Lego® in which metal cations or metal clusters represent the bricks (or nodes) and organic ligands such as 4,4-bipyridine (bipy) or benzene-dicarboxylate represents the glue (or spacers). The "node-and-spacer" approach to self-assembly can be invoked in such a manner that a plethora of infinite architectures and discrete polyhedra can be generated from geometric principles, some of which are unprecedented …
