Psychometric Functions Of Clear And Conversational Speech For Young Normal Hearing Listeners In Noise, Jane Smart

USF Tampa Graduate Theses and Dissertations

Clear speech is a form of communication that talkers naturally use when speaking in difficult listening conditions or with a person who has a hearing loss. Clear speech, on average, provides listeners with hearing impairments an intelligibility benefit of 17 percentage points (Picheny, Durlach, & Braida, 1985) over conversational speech. In addition, it provides increased intelligibility in various listening conditions (Krause & Braida, 2003, among others), with different stimuli (Bradlow & Bent, 2002; Gagne, Rochette, & Charest, 2002; Helfer, 1997, among others) and across listener populations (Bradlow, Kraus, & Hayes, 2003, among others). Recently, researchers have attempted to compare their …

An Experimental Analysis Of Activist Message Strategy Effect On Receiver Variables, Andrea Schuch

USF Tampa Graduate Theses and Dissertations

Utilizing communication and activist organization perspectives, this empirical study examined activist message strategies and how they influence variables related to the receiver of activist communication. Specifically, J.E. Grunig's (1997) situational theory of publics and Fishbein and Ajzen's (1975) theory of reasoned action were used to explain the communication effects of the seven activist message strategies developed from Hazleton and Long's (1988) public relations process model. The findings of this study support the premise of situational theory of publics and contribute to the extension of the theory through the inclusion of goal compatibility as a predictor of information seeking behavior and …

The Impact Of Management’S Tone On The Perception Of Management’S Credibility In Forecasting, Robert D. Slater

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to examine the impact of management altering its tone in communications on participants' perceptions of management credibility. Management's tone in communicating with participants was manipulated using communications from management under two treatment conditions. In period one of the study management's tone was manipulated within the management statement on internal controls as required by the Public Company Accounting Oversight Board's (PCAOB) Auditing Standards No. 2. In period one, participants had no knowledge of management's prior forecasting accuracy. Consistent with predicted hypotheses, the findings reveal that management can increase its credibility with participants by communicating its …

Vadose Zone Processes Affecting Water Fluctuations: Conceptualization And Modeling Considerations, Nirjhar Shah

USF Tampa Graduate Theses and Dissertations

This dissertation focuses on a variety of vadose zone processes that impact water table fluctuations. The development of vadose zone process conceptualization has been limited due to both the lack of recognition of the importance of the vadose zone and the absence of suitable field data. Recent studies have, however, shown that vadose zone soil moisture dynamics, especially in shallow water table environments, can have a significant effect on processes such as infiltration, recharge to the water table, and evapotranspiration. This dissertation, hence, attempts to elucidate approaches for modeling vadose zone soil moisture dynamics. The ultimate objective is to predict …

Methods To Improve Bond On Frp Wrapped Piles, Andy Schrader

USF Tampa Graduate Theses and Dissertations

Fiber Reinforced Polymer (FRP) sheets can provide incredible structural strength while weighing only a fraction as much as steel. When applied to piles the FRP provides strengthening through both concrete confinement and tensile reinforcement. Mainly used in structural repair, its application is relatively simple in theory. However, many factors(some avoidable, some not) can interfere with the bond between FRP and concrete. When this bond is interrupted the strength of the repair becomes compromised.This thesis examines 2 new methods of improving FRP bond to concrete piles during the time the resin is curing. These methods are compared using 3 types of …

The Proteoglycan Perlecan Regulates Long Bone Growth Through Interactions With Developmental Proteins In The Growth Plate, Simone Marsha-Lee Smith

USF Tampa Graduate Theses and Dissertations

Perlecan is the major heparan sulfate proteoglycan (HSPG) in growth plate cartilage and is critical for growth plate chondrocyte proliferation and proper skeletal development. Its core protein and attached chondroitin sulfate (CS) and heparan sulfate (HS) chains mediate interactions with many diverse proteins. Fibroblast growth factor (FGF)-2 and FGF-18 are other regulators of chondrocyte proliferation in the growth plate. Additionally, FGF-18 controls the hypertrophy and cartilage vascularization necessary for endochondral ossification. The research presented in this dissertation aimed to identify known and novel perlecan-binding proteins that are endogenous to the growth plate and to characterize their interactions with perlecan. FGF-2 …

A Theoretical Model For Self-Assembly Of Flexible Tiles, Ana Staninska

USF Tampa Graduate Theses and Dissertations

We analyze a self-assembly model of flexible DNA tiles and develop a theoretical description of possible assembly products. The model is based on flexible branched DNA junction molecules, which are designed in laboratories and could serve for performing computation. They are also building blocks for make of even more complex molecules or structures. The branched junction molecules are flexible with sticky ends on their arms. They are modeled with "tiles", which are star like graphs, and "tile types", which are functions that give information about the number of sticky ends. A complex is a structure that is obtained by gluing …

Scissors Paper Rock, Barbara St. Clair

USF Tampa Graduate Theses and Dissertations

Scissors Paper Rock is based on the true story of Amy Biel, a young and idealistic American woman who went to South Africa to support the political effort against Apartheid. She worked there as a volunteer organizer during a time of great political turmoil, and was days away from returning home to the United States, when she was violently killed in a riot. While Amy's death was not an accident--four men were found guilty for taking her life--it is certainly possible to think of her death as a tragedy. Amy's idealism and belief in her power to do good, allowed …

Cellular Electrofusion Utilizing Corona Fields And Dc Pulse Technology, Joshua Stein

USF Tampa Graduate Theses and Dissertations

Cell fusion is an important technique that is used in the field of medicine and biomedical research. For instance, fusion can be used to create hybridomas and novel types of secretory hybrid cells. It may also be used to engineer cultured insulin-secreting pancreatic B-cell lines for the treatment of diabetes. Historically, the applications listed above have been accomplished by a number of methodologies including dielectrophoresis, centrifugation, polyethylene glycol (PEG) and viral fusion proteins. However, these approaches often fail to produce the desired results due to poor cell viability, lack of 1:1 fusion, and use of non-physiological environments. It is proposed …

Enduring Changes In Reward Mechanisms After Developmental Exposure To Cocaine: The Role Of The D2 Receptor, Kirstie H. Stansfield

USF Tampa Graduate Theses and Dissertations

During adolescent brain maturation, there are likely sensitive periods where environmental conditions, including drug exposure, may influence development by modifying neuronal connections. Altering neuronal function may produce different phenotypes than expected under normal conditions that may influence subsequent responding to drugs of abuse after the brain is fully mature. Experiment one investigated the relationship between novelty preference and cocaine place preference in adolescent and adult rats. High responding adolescent rats displaying greater free choice novelty exploration (but not forced novelty locomotion) expressed decreased cocaine place conditioning compared to low responding rats. No relationship was found in adult rats. Experiment two …

Clinical Supervision Of Child And Adolescent Counselors In Residential Foster Care: A Collective Case Study, Lee A. Teufel

USF Tampa Graduate Theses and Dissertations

A collective case study is the study of more than one case (Stake, 1995). One therapist supervisor and three therapist supervisees from a child and adolescent residential foster care facility were observed during their individual clinical supervision and interviewed post-supervision. Currently, the literature on clinical supervision seldom addresses the supervision of working professional counselors; particularly those who are child and adolescent counselors (CACs).

Using a qualitative approach, two fundamental questions guided this inquiry: (a) what is the nature of clinical supervision involving a supervisor who provides clinical supervision to counselors in a child and adolescent residential foster care center that …

USF Tampa Graduate Theses and Dissertations

Aerial surveys were conducted throughout Hervey Bay Marine Park between August and October 1992 and 2004 to determine changes in abundance and distribution of the Eastern Australia humpback whale population in this area. Due to concerns about possible effects of boat traffic on whale distributions associated with a growing whale watching industry, the number and location of vessels were also recorded during these surveys. Throughout the 1992 season, 17 flights were conducted and a total of 41.93 surveys hours were completed, recording 186 pods, and a total of 320 animals. In addition, 392 boats were spotted in the area. During …

The Proliferating Sacred: Secularization And Postmodernity, Donald Surrency

USF Tampa Graduate Theses and Dissertations

When analyzing the role religion plays in contemporary American society, one is forced to address the notion of secularization. This is a term that broadly refers to the marginalization of religious influence in culture and society that began at the outset of the Enlightenment, sometime during the sixteenth and seventeenth centuries, but, as Peter Berger argues, can actually be traced back to the times of the great Israelite prophets who emerged during the Axial Age (800-200 BCE). Throughout the available literature, proponents of the secularization thesis extend the marginalization of religious influence from the societal level to the level of …

Life As A Student At An Independent Day School, Diana R. Torres

USF Tampa Graduate Theses and Dissertations

This study explores the interconnectedness of social class, education, and cultural capital. Considered academically elite, the independent school is be an ideal environment to find increased instances and opportunities for the acquisition and reproduction of elite, or "dominant" cultural capital. By implementing an ethnographic approach within an independent school setting, this study attempts to illuminate the student experience through adolescents' eyes. Past cultural capital studies focus on the relationship between cultural capital and academic achievement and/or social reproduction; instead, this study focuses on the everyday student experiences as they point to potential indicators of cultural capital. Results suggest that students' …

Uncertainty In The Information Supply Chain: Integrating Multiple Health Care Data Sources, Monica Chiarini Tremblay

USF Tampa Graduate Theses and Dissertations

Similar to a product supply chain, an information supply chain is a dynamic environment where networks of information-sharing agents gather data from many sources and utilize the same data for different tasks. Unfortunately, raw data arriving from a variety of sources are often plagued by errors (Ballou et al. 1998), which can lead to poor decision making. Supporting decision making in this challenging environment demands a proactive approach to data quality management, since the decision maker has no control over these data sources (Shankaranarayan et al. 2003). This is true in health care, and in particular in health planning, where …

Androgen Receptors In The Bonnethead Shark, Sphyrna Tiburo: Cdna Cloning And Tissue-Specific Expression In The Male Reproductive Tract, John P. Tyminski

USF Tampa Graduate Theses and Dissertations

Androgens and the androgen receptor (AR) play important roles in virilization, spermatogenesis, and sexual behavior in vertebrates. An understanding of the distribution and levels of expression of the ARs on the cellular and tissue level demonstrates the pattern of responsiveness to the androgenic hormones in a given organism. In this study, a fragment of the AR gene was cloned and sequenced from the bonnethead shark, Sphyrna tiburo, an elasmobranch species with a well-defined annual reproductive cycle. Acquiring this gene sequence facilitated the construction of species-specific AR polymerase chain reaction (PCR) primers and species-specific AR mRNA probes that were used to …

Narrative Efforts At Social Redemption By People With Aids/Hiv, Andrea Zolnier Thelen

USF Tampa Graduate Theses and Dissertations

This dissertation explores four narrative texts written about AIDS/HIV and evaluates each one by applying Kenneth Burke's redemption drama, consisting of guilt, purification, and redemption. The methodology is a close textual analysis using rhetorical analysis as a way to highlight the use of the redemption drama in language. The first chapter explores the history of AIDS/HIV and makes the argument for using Burke's rhetorical approach. The second chapter briefly highlights the plot of the four narratives and provides background information and context for each book. The third chapter applies the concept of guilt to all four narratives. The fourth chapter …

Greater Flexibility, Greater Growth: A Comparative Study Of Labor And Capitalist Models In Japan, Germany And The United States, Jay Arthur Thompson

USF Tampa Graduate Theses and Dissertations

After the end of the Second World War, three major economic powers emerged. Japan in Asia, Germany in Europe, and the United States in North America, quickly became the economic engines of their respective regions. Japan, with its "catch-up" and producer centered economy, grew so fast and so large, that there were worries in America that the Japanese would end up winning the economic war. West Germany, supported by the capitalist world, became a miracle economy, and the economic power of the European Union. In the past fifteen years however, these two economies have faltered and stagnated. In Japan, the …

Brevetoxins In Marine Birds: Evidence Of Trophic Transfer And The Role Of Prey Fish As Toxin Vector, Michelle Van Deventer

USF Tampa Graduate Theses and Dissertations

Harmful algal blooms (HABs) of the brevetoxin-producing dinoflagellate Karenia brevis occur periodically along the central west coast of Florida. Mass mortalities of marine birds have long been associated with these blooms, yet there is little data documenting the accumulation of brevetoxins in the tissues of birds and their prey items. An intense HAB event impacted the region from Tampa Bay to Charlotte Harbor during most of 2005. More than one hundred marine birds, representing twenty three species, were collected during this bloom. All birds sampled were found dead or had died within 24 hours of admittance to local wildlife rehabilitation …

What The Spirit Knows: Charles Williams And Kenneth Burke, Grace Veach

USF Tampa Graduate Theses and Dissertations

What the Spirit Knows: Charles Williams and Kenneth Burke examines the Arthurian poetry of Charles Williams using a methodology derived from Kenneth Burke. This is an experiment in literary criticism of a Christian poet using a methodology that is not specifically Christian. Key critical ideas found in Burke are utilized in reading poems from Taliessin Through Logres and Region of the Summer Stars. Burke's work on form and symbol (primarily from Counter-Statement) is addressed first. Form in an individual poem (using "Taliessin's Song of the Unicorn) and in an entire cycle is examined. Burke lists several uses for symbol in …

Local Strategies In A Global Network: Disability Rights Advocacy In Jamaica, Joan A. Tucker

USF Tampa Graduate Theses and Dissertations

The declaration of the International Year of Disabled Persons in 1981 and the international activism of persons with disabilities resulted in the globalization of disability, which involved a new framework for the treatment of PWDs. Although disability activism was being played out globally, it has been about PWDs gaining equality and full participation in their local societies. Therefore, at the heart of an international movement was the strategic organization of PWDs, most of who live in the developing world. This dissertation is based on a case study of activism for disability rights in one particular developing society, Jamaica. The Jamaican …

Defining Service Quality In An Outpatient Clinic With Complex Constituency, Swati Verma

USF Tampa Graduate Theses and Dissertations

The 2001 Institute of Medicine's (I.O.M.) landmark report, Crossing the Quality Chasm: A New Health System for the 21st Century observes that, "[though] medical science and technology have advanced at a rapid pace,...the health care delivery system has floundered in its ability to provide consistently high-quality care" (I.O.M. 2001). The report recommended six quality aims for a twenty-first century health care system; one of them being patient-centered care. It explains patient-centered care as "providing care that is respectful of and responsive to individual patient preferences, needs, and values and ensuring that patient values guide all clinical decisions" (I.O.M. 2001). This …

Immunomodulatory Role Of Flagellin In Antigen-Presenting Cells, Ildefonso Vicente-Suarez

USF Tampa Graduate Theses and Dissertations

Toll-like receptors (TLRs) expressed by cells of the immune system play a central role in the generation of immune responses against pathogens. Following TLR ligation, both pro-inflammatory and anti-inflammatory mediators are produced in order to elicit an immune response that controls the microbial infection while limiting tissue damage. Among these mediators, the proinflammatory cytokine IL-12 and the anti-inflammatory cytokine IL-10 are known to play major roles. Here, we show that in vitro or in vivo stimulation with flagellin, the TLR5 ligand, does not result in IL-10 production. Furthermore flagellin inhibits IL-10 production by other specific TLR ligands at the protein …
