USF Tampa Graduate Theses and Dissertations

The purpose of this study is to determine the frequency with which college sports information directors (SIDs) are promoted to athletics director (AD) positions. Results reveal some reasons why SIDs, the primary communications officer in the athletics department, may or may not be considered as qualified candidates for AD jobs. This study illustrates that current ADs predominately come from the ranks of former coaches, compliance officers, business managers and fund raisers, while few were formerly SIDs. In addition, this study sought to determine whether the SID develops skills and experience most closely related with ADs.

The variables examined in this …

The Essay In The Postmodern Era, Xiqiao Wang

USF Tampa Graduate Theses and Dissertations

The overarching goal of this study is to suggest that the essay as a genre, although seeming to manifest the epistemological conceptions of the modern, possesses certain qualities from its origin that justify and strengthen its position in the paradigm of the postmodern condition. It is my argument that misconceptions about such qualities have led to its mistreatment by writing teachers in accordance with two dominant pedagogical approaches, formalism (current-traditionalism) and romanticism (expressivism). My argument requires a detailed examination of the political, historical and cultural reality that cultivated and nurtured the genre of the essay, and a major focus of …

A Comparison Of Tone Burst Auditory Brainstem Response (Abr) Latencies Elicited With And Without Notched Noise Masking, Rachele M. Orsini

USF Tampa Graduate Theses and Dissertations

Objective: The air conduction click is currently the most widespread stimulus used to estimate the pure tone audiogram as part of auditory brainstem response (ABR) testing. The click is characterized by its broad spectral content and rapid onset, which may not make it the best choice for frequency specificity. An alternative stimulus is a short duration tone burst stimuli with notched noise masking. When obtaining an ABR using standard unmasked tone bursts, the brief stimulus onset may cause spectral splatter producing response contributions from unwanted regions of the cochlea; thus reducing the frequency specificity of the ABR. Notched noise masking …

Towards Adaptation Of Ofdm Based Wireless Communication Systems, Sharath Reddy Billoori

USF Tampa Graduate Theses and Dissertations

OFDM has been recognized as a powerful multi-carrier modulation technique that provides efficient spectral utilization and resilience to frequency selective fading channels. Adaptive modulation is a concept whereby the modulation modes are dynamically changed based on the perceived instantaneous channel conditions. In conjunction with OFDM systems, adaptive modulation is a very powerful technique to combat the frequency selective nature of mobile channels, while simultaneously attempting to fully maximize the time-varying capacity of the channel. This is based on the fact that frequency selective fading affects the sub-carriers unevenly, causing some of them to fade more severely than others. The modulation …

Un Mandat, Deux Politiques : Les Effets De L’Inégalité De La Politique Mandataire Française En Syrie Et Au Liban, Catherine Glenn Ellis

USF Tampa Graduate Theses and Dissertations

In the early years of the twentieth century, the Ottoman Empire began to crumble due to external wars and internal rebellions dating from about 1908. Due to European influence at the end of the First World War, the Ottoman Empire lost much of its territory in 1919, including Palestine and Syria, comprised of modern-day Syria, Lebanon, Israel, Jordan, and Iraq. The European powers incited rebellion among the Middle Eastern peoples to the end of aiding their cause in the portions of the war fought in the Middle East.

From Just War To Just Peace: Re-Visioning Just War Theory From A Feminist Perspective, Naomi Malone

USF Tampa Graduate Theses and Dissertations

This paper studies the history of just war theory and critiques it from various feminist perspectives. Using a definition of war as inseparable from the system within which it is embedded, the paper contends that just war theory has been incorporated into the realist paradigm that predominates current political thought, making it susceptible to manipulation. Most importantly, this usurpation has shifted just war theory's focus from jus ad bellum to jus in bello considerations, seriously weakening its deterrent effects on war. The paper proposes its replacement with a just peace theory, discussing several existing frameworks and explaining the important part …

Concerning Theories Of Personal Identity, Patrick, Bailey

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to provide a brief examination of the historical accounts of philosophical theories of personal identity and show the influence that each has had on the development of contemporary theories. In doing so, the thesis explores the problems associated with these theories, attempting to establish a meta-theory (i.e. a theory about theories) of personal identity. What is demonstrated is that the fundamental problems of personal identity arise from issues related to the use of language, as well as assumptions involving the concept of personhood.

By demonstrating that our understanding of personhood is relative to frameworks …

The Politics Of Being An Egg “Donor” And Shifting Notions Of Reproductive Freedom, Elizabeth A. Dedrick

USF Tampa Graduate Theses and Dissertations

As an Assisted Reproductive Technology (ART) that has been available for over twenty years, the transfer of healthy eggs from a presumably fertile woman into the womb of a woman diagnosed as infertile has become a common part of the landscape of human reproduction in the United States. Yet the general societal acceptance of this practice commonly known as "egg donation" oversimplifies the complex medical, ethical, and societal issues ignited by its use. In light of the limited critical discussions presently occurring about egg transfer, I will interrogate some of the silences and more ambiguous issues invoked by its practice. …

Investigation Of Oxide Thickness Dependence Of Fowler-Nordheim Parameter B, Shashank Bharadwaj

USF Tampa Graduate Theses and Dissertations

During recent years the thickness of the gate oxide has been reduced considerably. The progressive miniaturization of devices has caused several phenomena to emerge such as quasi-breakdown, direct tunneling and stress induced leakage currents. Such phenomena significantly modify the performance of the scaled-down MOSFETs. As a part of this research work, an effort has been made to study the performance and characteristics of the thin Gate oxide for MOSFETs and Tunnel Oxide for Floating Gate (FG) MOS devices. The exponential dependence of tunnel current on the oxide-electric field causes some critical problems in process control. A very good process control …

The Social Construction Of Workplace "Diversity", Brenda G. Shawver

USF Tampa Graduate Theses and Dissertations

This is a study of "workplace diversity" from a social constructionist perspective. The perspective holds that while human meaning is socially created, it is the social order which gives us resources for making this meaning. There is much literature about workplace diversity from objectivist standpoints that takes for granted the term "diversity." What is missing is a comprehensive understanding of diversity: what does this term mean? What does it conceal? I attempt to contribute to a better understanding of diversity by interrogating its construction in popular culture.

I analyze the content of an advertising supplement called "Diversity Works," published in …
