The Single Market And Pharmaceutical Industry In The European Union: Is There Any Evidence Of Price Convergence?, Aysegul Timur

USF Tampa Graduate Theses and Dissertations

During the last two decades, the European Union (EU) has experienced closer market integration through the removal of trade barriers, the establishment of a single market, and the reduction of exchange rate volatility. In addition, there have been several structural reforms in product markets designed to increase competition, monitor cross-country price differences and increase transparency. One anticipated effect of market integration is price convergence, because of the reduced potential for price discrimination across the EU. This dissertation explores market integration and price convergence in the European pharmaceutical market, which is the fifth largest industry in the EU. Since 1985, many …

An Investigation Of The Relationship Between Religiosity And Subjective Well-Being In Older Adults: The Mediating Role Of Optimism, Teri A. Trede

USF Tampa Graduate Theses and Dissertations

The proportion of adults aged 65 and older in the United States has been increasing steadily for years. Although most would agree that this increased longevity is a remarkable achievement, there is growing concern regarding the resources that will be necessary to provide care and services for this rapidly expanding segment of the population. From a public health perspective, simply increasing longevity is no longer the ultimate outcome sought. A more pertinent goal is increasing the quality of life years, or promoting resilience and successful aging. Strategies that assist adults in delaying the onset of disability or reducing the severity …

A Case Study Of The Perceived Decision-Making Practices And Patterns Of Secondary Administrators Using Four Scenarios, Elizabeth M. Tuten

USF Tampa Graduate Theses and Dissertations

This research study explored practitioners' perceived understanding and situational use of seven decision-making models of educational administration. In examining the extant literature of the field, the following research problem emerged to guide this study: scholars and practitioners struggle to understand how school administrators make workplace decisions, and how school leaders perceive their decision-making strategies and actions. Based upon Pettigrew's (1985) Conceptual Framework of Organizational Change and relevant literature (see chapter 2), the researcher developed a series of questions in order to explore the aforementioned purpose and problem. Specifically, three principals, three assistant principals of curriculum, and three assistant principals for …

A Closer Look At The Work Hours And Work/Family Relationship: The Moderating And Enhancing Effects Of Fit, Matthew D. Tuttle

USF Tampa Graduate Theses and Dissertations

Managing the conflict between work and family role demands is a critical issue that has generated substantial interest for both individuals and organizations in recent decades. One factor thought to contribute to the occurrence of work-family conflict (WFC) is the amount of time committed to activities in either the family or to the work domain. Because time is a finite resource, it has been posited that when one dedicates a certain amount of time to one domain, this will invariably take away from the amount of time available for activities in the other domain. The result of this is conflict …

Communicating Change: An Ethnography Of Women’S Sensemaking On Menopause, Hormone Replacement Therapies, And The Women’S Health Initiative, Linda Vangelis

USF Tampa Graduate Theses and Dissertations

As a result of the recent findings of the Women's Health Initiative (WHI), many women who have been on hormone replacement therapies (HRT) have begun to renegotiate their understandings and strategies of this stage of their lives. The WHI findings suggested that the risks of HRT outweighed the benefits for healthy menopausal women. This study examined women's emerging sensemaking regarding HRT and menopause in light of the WHI findings. Seven women in the Tampa Bay area, who were in various stages of menopause, participated in three focus group sessions and two one-on-one interviews to discuss their lives in menopause. Based …

“Trust Yourself To God:” Friar Francisco Pareja And The Franciscans In Florida, 1595-1702, Albert William Vogt

USF Tampa Graduate Theses and Dissertations

Friar Francisco Pareja represented the pinnacle of the achievement for the Franciscans in Florida during the Spanish colonial period. But who were the Franciscans? Why were they, and Friar Pareja in particular, so successful as missionaries? The bulk of the writing done thus far on the mission system in Florida has concentrated on retelling the lost story of the native peoples who once inhabited the land. The impact of the missions and the Spanish colony weighed heavily on native cultures and the Franciscans role in this has been discussed. However, little has been said about the religious order itself, and …

ArcGIS 9 was used to measure certain morphometric parameters from the spatial data for Florida's springs. Other Parameters representing physical and dimensional characteristics of the springs were acquired from FGS Bulletin 66, Springs of Florida. All measured and collected data was compiled into a usable morphometric database. The data is described statistically and summarized according to the spatial distribution of Florida's springs with respect to geology …

A Structural Approach To The Study Of Intra-Organizational Coalitions, Dean T. Walsh

USF Tampa Graduate Theses and Dissertations

Coalitions are widely associated with collective or collaborative attempts to influence organizational members, decisions, policies and events. Yet, surprisingly, relatively little is known about how coalitions develop within organizations. Employing an exploratory case study design and using social network analysis, the Rokeach Value Survey, and semi-structured interviews, this research demonstrated that it is possible to identify and study coalitions in a real organizational setting. I suggest that the inclusion and investigation of member relationships may advance the state of the art in organizational coalition research. A benefit of this study, and contrary to most coalition research, is that it used …

Linkages Between Environmental Conditions And Recreational King Mackerel Catch Off West-Central Florida, Carrie C. Wall

USF Tampa Graduate Theses and Dissertations

The objective of this study was to determine if fronts sustained up to three days will result in an aggregation of kingfish due to the anticipated accumulation of forage, increasing fishing success at these locations. Automated algorithms to detect frontal features in satellite-derived sea surface temperature, chlorophyll concentration, water clarity, and fluorescence images were successfully adapted for the coastal waters off west-central Florida. The surface ocean fronts were used to study the linkages between environmental conditions and recreational catch statistics of king mackerel (Scomberomorus cavalla) during 19 seasonal tournaments held in April to May and October to November of 2004 …

Associations Between Individual, Social, And Service Factors, Recovery Expectations And Recovery Strategies For Individuals With Mental Illness, Gary W. Walby

USF Tampa Graduate Theses and Dissertations

Clinical and consumer recovery efforts continue to advance more successful recovery agendas. Limited research into the effect of the expectation to recover and what strategies are most effective in enhancing recovery impedes coherent recovery programming. What factors are significantly associated with recovery expectancy and recovery strategies is still largely unknown. Thus, this study addresses three key gaps in the field.

First, which factors associate with the expectation of recovery and is expectation related to strategy choice? Second, what are common strategies for recovery from mental illness and what factors are associated with each strategy? Third, does recovery expectancy or severity …

Cross-Dressing In Sarah Grand's The Tenor And The Boy And E.D.E.N Southworth's The Hidden Hand: Gender, Class, And Power, Marcy Wynn Murray

USF Tampa Graduate Theses and Dissertations

This thesis concerns female cross-dressing in nineteenth-century literature and the ways in which these images challenge gender and class hierarchies. Cross-dressing abounds in nineteenth-century literature, forming a thematic that crosses national boundaries. Therefore, this thesis considers works from both the British and American traditions. The primary texts explored are The Tenor and the Boy (1893) by Sarah Grand and The Hidden Hand, or Capitola the Madcap (1888) by E. D. E. N. Southworth. When published, both of these texts were commercial successes and can therefore be considered representative of popular literature of the time.

The use of transvestite characters allows …

What Is The Effect Of Retrieval Practice On Competing Associates In Cued-Recall?, Umit Akirmak

USF Tampa Graduate Theses and Dissertations

There have been many theories on why we forget. One of the recent approaches to this phenomenon is retrieval induced forgetting (RIF). The present study investigated RIF and different kinds of disruptions and their effects by using extra-list cued recall task. Some participants studied two additional word lists after the target list and some participants studied and were tested from these interpolated lists before their final recall of target list. Relatedness of the interfering lists was also manipulated. There were two control groups that either got an immediate test or got a math task before memory test. The particular interest …

Interspecific Interactions Among Common Insects Of The Salt Myrtle, Baccharis Halimifolia L. (Asteraceae), Laura F. Altfeld

USF Tampa Graduate Theses and Dissertations

Baccharis halimifolia is host to many species of insect herbivore, including myrmecophilous aphids. Previous studies with B. halimifolia have revealed strong effects of competition by an early-feeding beetle, Trirhabda bacharidis, and nitrogen enrichment. The effects of ant mutualists, however, have not been evaluated for their potential influence on interspecific interactions among insects on the host plant. I have employed a series of experiments aimed at answering the following general questions. (1) How does the density of aphid-tending ants affect common insects on the host plant? (2) What are the relative effects of (a) competition from T. bacharidis, (b) nutrient enrichment, …

Polynomial Quandle Cocycles, Their Knot Invariants And Applications, Kheira Ameur

USF Tampa Graduate Theses and Dissertations

A quandle is a set with a binary operation that satisfies three axioms that corresponds to the three Reidemeister moves on knot diagrams. Homology and cohomology theories of quandles were introduced in 1999 by Carter, Jelsovsky,Kamada, Langford, and Saito as a modification of the rack (co)homology theory defined by Fenn, Rourke, and Sanderson. Cocycles of the quandle (co)homology, along with quandle colorings of knot diagrams, were used to define a new invariant called the quandle cocycle invariants, defined in a state-sum form. This invariant is constructed using a finite quandle and a cocyle, and it has the advantage that it …

The Relationship Between B-Type Natriuretic Peptide Levels And Hospital Length Of Stay And Quality Of Life In Congestive Heart Failure Patientsthe Relationship Between B-Type Natriuretic Peptide Levels And Hospital Length Of Stay And Quality Of Life In Congestive Heart Failure Patients, Irma B. Ancheta

USF Tampa Graduate Theses and Dissertations

Previous research on quality of life (QOL) and its relation to BNP levels in heart failure (HF) has been widely studied. However, the impact of physicians' knowledge of BNP levels at time of clinic visit on QOL and hospital length of stay (LOS) has yet to be fully investigated. The purpose of this study were to determine if physicians' knowledge of BNP levels affected a change in QOL scores at 90 days and reduce hospital length of stay among heart failure patients. QOL data from HF clinic patients (N = 108, 67.5 ± 12.3, 56% male, ejection fraction 26.5 ± …

A Comparison Of Systolic Blood Pressure In Women With And Without Lymphedema Following Surgery For Breast Cancer, Deborah M. Arvidson-Hawkins

USF Tampa Graduate Theses and Dissertations

There is no evidenced-based research on prevention of upper extremity lymphedema following breast cancer treatment. General guidelines have been identified from a basic understanding of the lymphatic system and are considered to be prudent advice for prevention. Cause of lymphedema is hypothesized to be multifactorial and time of onset is widely varied. Exogenous risk factors leading to lymphedema are the removal and destruction of lymph nodes; however, not all women develop lymphedema following axillary lymph node dissection. Co-morbid conditions such as obesity, diabetes, and hypertension are cited as possible endogenous risk factors. Several studies identify hypertension as a significance endogenous …

A Compiler-Based Leakage Reduction Technique By Power-Gating Functional Units In Embedded Microprocessors, Soumyaroop Roy

USF Tampa Graduate Theses and Dissertations

Power-gating is a technique investigated widely for reducing leakage energy in the functional units of microprocessors at the architectural level. Effective power-gating involves deactivating idle functional units for sustained periods incurring little or no performance degradation. Accurate prediction of long idle periods is essential, which, in turn, depends on the application program characteristics.In this thesis, we propose a compiler-based leakage reduction technique for embedded architectures by exploiting the well-known attributes of embedded applications, namely, small code size and intensive loops. From the control flow graph (CFG) representation of the source program, we construct a forest of loop hierarchy trees (LHTs), …

Ultrawideband (UWB) is one of the promising technologies for future short-range high data rate communications (e.g. for wireless personal area networks) and longer range low data rate communications (e.g. wireless sensor networks).Despite its various advantages and potentials (e.g. low-cost circuitry, unlicensed reuse of licensed spectrum, precision ranging capability etc.), UWB also has its own challenges. The goal of this dissertation is to identify and address some of those challenges, and provide a framework for practical UWB transceiver design.In this dissertation, various modulation options for UWB systems are reviewed in terms of their bit error rate (BER) performances, spectral characteristics, modem …

Respondent Fatigue In Self-Report Victim Surveys: Examining A Source Of Nonsampling Error From Three Perspectives, Timothy C. Hart

USF Tampa Graduate Theses and Dissertations

Survey research is a popular methodology used to gather data on a myriad of phenomena. Self-report victim surveys administered by the Federal government are used to substantially broaden our understanding of the nature and extent of crime. A potential source of nonsampling error, respondent fatigue is thought to manifest in contemporary victim surveys, as respondents become "test wise" after repeated exposure to survey instruments. Using a special longitudinal data file, the presence and influence of respondent fatigue in national self-report victim surveys is examined from three perspectives. Collectively, results provide a comprehensive look at how respondent fatigue may impact crime …

Growth Of 3c-Sic Via A Hot-Wall Cvd Reactor, Suzie Harvey

USF Tampa Graduate Theses and Dissertations

The heteroepitaxial growth of cubic silicon carbide (3C-SiC) on silicon (Si) substrates at high growth rates, via a horizontal hot-wall chemical vapor deposition (CVD) reactor, has been achieved. The final growth process was developed in three stages; an initial "baseline" development stage, an optimization stage, and a large area growth stage. In all cases the growth was conducted using a two step, carbonization plus growth, process. During carbonization, the surface of the Si is converted to 3C-SiC, which helps to minimize the stress in the growing crystal. Propane (C3H8) and silane (SiH4), diluted in hydrogen (H2), were used as the …

Ventricle Slice Detection In Mr Images Using Hough Transform And Object Matching Techniques, Chintan Thakkar

USF Tampa Graduate Theses and Dissertations

The determination of the center slice, defined as a slice through the lateral ventricles in the axial plane in a volume of MR images is important to the segmentation of the image into its anatomical parts. The center or ventricle slice in a set of MR images is recognized by the shape of the ventricles in the axial plane as depicted by the cerebro-spinal fluids in the image. Currently, no technique exists to detect this slice and the purpose of this thesis is to find a slice through the lateral ventricles in the axial plane from a volume of MRI …

This dissertation focuses on the development of conductive window layer for the development of a high performance, high bandgap solar cell. ZnSe, Cu2-xSe, and ZnSexTe1-x are investigated as viable window layers of the top cell. ZnSe in undoped form forms a good junction with CdSe films, but the Voc from these devices could never exceed the 360mV mark, while the current …

Freedom Fighters, Freedom Haters, Martyrs, And Evildoers: The Social Construction Of Suicide Terrorism, Cã©Cile Valã©Rie Van De Voorde

USF Tampa Graduate Theses and Dissertations

Suicide terrorism is characterized by the willingness of physically and psychologically war-trained individuals to die while destroying or attempting to annihilate enemy targets in furtherance of certain political or social objectives. Rooted in the historical, social, and psychological dimensions of international terrorism, suicide terrorism is neither a unique nor a new phenomenon. Its recent resurgence and the extensive media coverage it has received account for the misleading uniqueness of this violent, complex, and adaptive form of terrorism. This qualitative study examines the definitional and rhetorical processes by which suicide terrorism is socially constructed. Using a social constructionist theoretical framework coupled …

An Exploration Of Middle-Aged And Older Women's Experiences Of Bat Mitzvah Within The Framework Of Erikson's Theory Of Human Development, Keren S. Vergon

USF Tampa Graduate Theses and Dissertations

A growing number of Jewish women are participating in adult bat mitzvah ceremonies in many synagogues across the United States. Little is known about the reasons why women choose to participate in a bat mitzvah ritual as an adult. It is also unclear if women of different ages have different reasons for participating in bat mitzvah.Older women were often not given the opportunity to participate in the bat mitzvah ritual as a young adult, and it is unknown why older women choose to accept the challenge of bat mitzvah. It may be suspected that Jewish women are interested in adult …

Novel Sol-Gel Titania-Based Hybrid Organic-Inorganic Coatings For On-Line Capillary Microextraction Coupled To High-Performance Liquid Chromatography, Tae-Young Kim

USF Tampa Graduate Theses and Dissertations

Novel sol-gel titania-poly(dimethylsiloxane) (TiO2-PDMS) and titania-silica-N-(triethoxysilylpropyl)-O-polyethylene oxide urethane (TiO2-SiO2-TESP-PEO) coatings were developed for capillary microextraction (CME) to perform on-line preconcentration and HPLC analysis of trace impurities in aqueous samples. Due to chemical inertness of titania, effective covalent binding of a suitable organic ligand to its surface is difficult via conventional surface modification methods. In this research, sol-gel chemistry was employed to chemically bind hydroxy-terminated poly(dimethylsiloxane) (PDMS) and N-(triethoxysilylpropyl)-O-polyethylene oxide urethane (TESP-PEO) to sol-gel titania and sol-gel titania-silica network, respectively. A method is presented describing in situ preparation of the titania-based sol-gel PDMS and TESP-PEO coatings and their immobilization on the …

Vigilance In African Americans: Cardiovascular Reactivity And Phasic Heart Period Reactions To Cued Threat And Nonthreat Stimuli, Thomas Starr King

USF Tampa Graduate Theses and Dissertations

African Americans are at a greater risk of developing cardiovascular disease and associated risk factors than are Whites, and recent research has suggested that the effects of racial discrimination are a significant contributor to this disparity. Thus, a preattentive bias and vigilance for threat might serve as a mechanism through which experienced racial discrimination would negatively impact cardiovascular health. A study was conducted to investigate the physiological and attentional underpinnings of vigilance for discriminatory threat via examination of phasic heart period (HP) responses to cued threat and nonthreat stimuli. Thirty African American and forty-two European American undergraduate students from a …

Workers, Unions, And The Globalization Of Production: Structural And Institutional Challenges For Organized Labor In The United States, Matthew Kohen

USF Tampa Graduate Theses and Dissertations

In this thesis, I argue that the globalization of production has weakened the power and efficacy of labor unions in the United States. I describe the globalization of production as a set of transformations in both the institutional structure of the economy and in the organization of production, and discuss how these transformations have impacted workers and unions in the American economy. The theoretical framework I employ is the social structure of accumulation approach, which emphasizes the importance of the institutional structures of capitalist economies and how their interaction with forms of production organization and systems of labor control helps …
