Relationships Between Participation In Athletics And Substance Use Among School Students, Kevin M. Stockslager

USF Tampa Graduate Theses and Dissertations

Substance use among high school students has become an increased concern for administrators, parents, and community members. Previous research has demonstrated relationships between adolescent substance use and numerous negative outcomes. This study investigated the relationship between athletic participation and substance use using self-report data from a sample of 139 high school students. Specifically, the current study examined the relationship between frequency and setting of participation in athletic activities (e.g., football, baseball, soccer) and multiple types of substance use (e.g., alcohol, tobacco, marijuana, other illicit drugs) in adolescents. The results of this study indicate that nonathletes reported significantly more marijuana use …

The Effect Of A Reasoning Warning On Faking In Personality Testing For Selection And The Perception Of Procedural Justice, T Ryan Dullaghan

USF Tampa Graduate Theses and Dissertations

A major concern with using personality tests in the selection process is the prevalence of applicant faking behavior which can influence the rank order of applicants such that fakers are hired at an elevated frequency. This study examined the effects of the detection/consequence warning and a more applicant-friendly warning on faking and perceived procedural justice. I hypothesized that a positive warning (reasoning warning) and a detection/consequence warning would show similar mean personality trait levels compared to honest responses, with all means showing less socially desirable responding than no warning prompt. Results suggested that the detection/consequence warning is more effective at …

Sharing The Power Of Words And Changing Lives Through College-Level Instruction In Grammar And Mechanics, Carol Ann Tillema

USF Tampa Graduate Theses and Dissertations

Intrigued by the English language and its far-reaching applications worldwide as a standard means of communication, I begin my disquisition with a focus on the meaning and derivation of grammar and its place in the trivium of ancient and modern study. I stress the need to reemphasize college-level instruction in grammar and mechanics as a complement to rhetoric and logic by studying and teaching editing, which involves semantics, syntax, phonology, morphology, conventions, mechanics (spelling, punctuation and format), in writing centers and classrooms. Noting growing nationwide illiteracy, I research the pedagogies and writing of experts in the field of rhetoric and …

Responding To Crises: A Test Of The Situational Crisis Communication Theory, Courtney Wright

USF Tampa Graduate Theses and Dissertations

Crisis management includes efforts designed to prevent and to detect potential crises, and to learn from crisis experiences. The SCCT posits that certain crisis responses (matched) produce better outcomes for organizations than others (unmatched), depending on the situation. In addition, the results from this study attempt to support the situational crisis communication theory in aiding crisis managers in protecting their organizations against crises.

Considerations Of Multicultural Science And Curriculum Reform: A Content Analysis Of State-Adopted Biology Textbooks In Florida, Margaret H. Delgato

USF Tampa Graduate Theses and Dissertations

The purpose of this investigation was to determine the extent to which multicultural science education, including indigenous knowledge representations, had been infused within the content of high school biology textbooks. The study evaluated the textbook as an instructional tool and framework for multicultural science education instruction by comparing the mainstream content to indigenous knowledge perspectives portrayed in the student and teacher editions of 34 textbooks adopted in Florida within the last four adoption cycles occurring from 1990 to 2006. The investigation involved a content analysis framed from a mixed methods approach. Emphasis was placed, in consideration of the research questions …

The Provision Of Spousal Support: Antecedents, Consequences, And Crossover Effects, Jay M. Dorio

USF Tampa Graduate Theses and Dissertations

The present study had four main objectives. First, the relationship between the provision of spousal support and its theoretical antecedents and consequences was assessed as informed by the conservation of resources theory (Hobfoll, 1989). Second, the crossover of physicians' work interference with family conflict on their spouses' family demands (perceived family demands and family hours) was investigated. Next, the mediating role of social support as an explanation for the crossover process was examined using two distinct pathways. Lastly, the fourth objective of the present study was to investigate the relationships described above across multiple time points and using dual-source data …

My Enemy’S Enemy Is My Friend: Why Holding The Same Negative Attitudes Of Others Promotes Closeness, Jonathan R. Weaver

USF Tampa Graduate Theses and Dissertations

Holding the same negative, as compared to positive, attitudes about a third party has been shown to predict increased liking for a future interaction partner (Bosson, Johnson, Niederhoffer, & Swann, 2006). The current work extended past research by examining two possible mediators of this effect: perceptions of "knowing" the future interaction party, and state self-esteem. Participants learned that they held the same positive or negative attitude of a professor with a future interaction partner, and then rated their feelings of "knowing" their partner, their own state self-esteem, and the closeness they felt to their future interaction partner. It was predicted …

Managing Geographic Data As An Asset: A Case Study In Large Scale Data Management, Clay Smithers

USF Tampa Graduate Theses and Dissertations

Geographic data is a hallowed element within the Geographic Information Systems (GIS) discipline. As geographic data faces increased usage in distributed and mobile environments, the ability to access and maintain that data can become challenging. Traditional methods of data management through the use of file storage, databases, and data catalog software are valuable in their ability to organize data, but provide little information about how the data was collected, how often the data is updated, and what value the data holds for an organization. By defining geographic data as an asset it becomes a valuable resource that requires acquisition, maintenance …

Metadrama And Antitheatricality In Shakespeare’S King Lear And Troilus And Cressida, Douglas R. Willcox

USF Tampa Graduate Theses and Dissertations

Shakespeare uses metadrama as a rhetorical vehicle for responding to antitheatricalism; realistic drama and staged theatricality therefore coexist in his plays. The cultural context of the early modern era, especially its antitheatrical rhetoric and the predominance of theatricality throughout the structures of its society, illumines the interaction of metadrama and antitheatricality Shakespeare's plays, particularly Troilus and Cressida and King Lear. By failing to consider adequately the unique nature of the emergence of early modern theater and the equally distinct reaction to its popularity, previous scholarship considering antitheatricality has exhibited essentialism and a universalizing tendency similar to that of the …

Great Apes And Other Stories, Ryan Zimmerman

USF Tampa Graduate Theses and Dissertations

Thoreau said that, "in wildness is the preservation of the world." The characters in the following collection of stories might be tempted to rephrase that statement to read, "in wildness is the preservation of the criminal world." These stories feature wild places where the natural world often is not as dangerous as the people who seek refuge in the borderlands between wilderness and civilization.

Many crime stories take place in cities-for good reason. More people usually equates with more crime. However, anywhere that people choose to live, crime is sure to follow-crime against each other, crime against themselves, and even …

Design And Implementation Of A Hard Real-Time Telerobotic Control System Using Sensor-Based Assist Functions, Eduardo J. Veras-Jorge

USF Tampa Graduate Theses and Dissertations

This dissertation presents a novel concept of a hard real-time telerobotic control system using sensory-based assistive functions combining autonomous control mode, force and motion-based virtual fixtures, and scaled teleoperation. The system has been implemented as a PC-based multithreaded, real-time controller with a haptic user interface and a 6-DoF slave manipulator. A telerobotic system is a system that allows a human to control a manipulator remotely and the human control is combined with computer control. A telerobotic control system with sensor-based assistance capabilities enables the user to make high-level decisions, such as target object selection, and it enables the system to …

Determination Of Decay Rates And Differential Survival Of Escherichia Coli And Enterococcus Spp. Strains Under Hydrodynamically Active Conditions Using Box-Pcr Typing, Phoebe West Koch

USF Tampa Graduate Theses and Dissertations

Indicator organisms (IOs) such as Escherichia coli and Enterococcus spp. are used to predict the presence of pathogens in waters. Determining the relationships between environmental factors, IOs, and pathogens is a key to assessing water quality and ensuring public health, yet certain strains of E. coli and Enterococcus spp. survive for long periods in natural waters. Molecular subtyping, using repetitive extragenic palindromic DNA sequences (BOX-PCR), has been used to discriminate among environmental E. coli and Enterococcus spp. isolates. The reproducibility of BOX-PCR patterns varies with DNA purification methods; therefore, it is important to develop a standardized, rapid, high throughput DNA …

Development Of Novel Biocompatible Hydrogel Coatings For Implantable Glucose Sensors, Chunyan Wang

USF Tampa Graduate Theses and Dissertations

Due to sensor -tissue interactions, currently none of the commercially available glucose sensors are capable of continuous, reliable monitoring of glucose levels during long-term implantation. In order to improve the lifetime of implanted glucose sensors, two series of biocompatible novel hydrogel coatings were designed, synthesized and the physical properties were measured.

Different hydrogels with various 2,3-dihydroxypropyl methacrylate (DHPMA) compositions were coated onto glucose sensors. Results show that the higher freezable water content, swelling rate and uniform porosity that resulted from high DHPMA content increased the sensitivity and shortened the response time of glucose sensors. The linear range of a glucose …

Analysis Of Pump Oil And Alkanes Evaporation, Nathaniel A. Waldstein

USF Tampa Graduate Theses and Dissertations

There are many products, including hard drives, which require trace amounts, on the order of several mg, of lubricants for proper operation. The following study investigated the evaporation rates of pump oil and several alkanes, which have a wide range of applications, using a thermogravimetric machine. Both static and dynamic temperature tests were conducted. The rate of evaporation of the test specimen was determined as the percentage of mass loss per unit time. Using the Arrhenius Equation, the activation energy of the evaporation process, Ea, can be calculated as the slope of the best fit line for a plot of …

Linking Health Hazards And Environmental Justice: A Case Study In Houston, Texas, Marilyn Marie Williams

USF Tampa Graduate Theses and Dissertations

This dissertation seeks to extend quantitative research on environmental justice and address methodological limitations of previous studies by: (a) using new indicators of exposure to air pollution and contemporary risk modeling techniques; (b) assessing disparities in human health risks, instead of focusing only on potential exposure or proximity to pollution sources; and (c) using multivariate regression models that consider the effects of spatial dependence. The case study examines racial/ethnic and socioeconomic disparities in the geographic distribution of exposure to airborne toxic emissions from industrial point sources in the Houston-Galveston-Brazoria metropolitan statistical area. Industrial pollution sources for this study comprise facilities …

An Address, Not A Room Number: An Assisted Living Community Within A Community, Gregory J. Novotnak

USF Tampa Graduate Theses and Dissertations

As the son of parents of the "baby boomer" generation I foresee the immanent increased demand for assisted living for the elderly. By 2030 an estimated 20 percent - one in five Americans - will be 65 or older. Unless attention is paid now to advancing the designs and opportunities for assisted-living, there will either be a distinct lack of available options, or worse, the continuation of out-dated designs that simply will not be a marketable.

Contemporary thinking with regard to the design of places of residence for the elderly has changed dramatically from the days of outdated structures and …

The First Icomde A Library For The Information Age, Daniel Elias Todd

USF Tampa Graduate Theses and Dissertations

The library has existed as a repository for knowledge for centuries. However, in spite of the information revolution and its watershed component, the internet, this institution has found itself fundamentally unchanged. Great strides have been taken to adapt the library to this changing world, but these incremental changes are timid and reactionary.

Through the internet the floodgates have opened; individuals are creating and sharing information both personal and academic, in the form of not-so-private journals, works of creative fiction, works of journalism, works of scholarship, and every other form of intellectual (and not so intellectual) propagation imaginable.

Additionally, advances in …

Urban Fabric As A Calayst For Architectural Awareness: Center For Architectural Research, Bernard C. Wilhelm

USF Tampa Graduate Theses and Dissertations

Architects throughout have been forced to practice design surrounded by a society that generally lacks of architectural awareness and interest. A growing trend to transition from a relatively isolated profession into a field that promotes stronger public involvement is critical for architecture to evolve. Within the past 10 years, the growth of architectural centers have begun to dissolve the barrier between the profession and the general public in that their primary function regardless of what form they represent, is to introduce and educate issues of architecture that are an inescapable part of our built environment.

An investigation of architectural research …

N-Acylethanolamines As Novel Alcohol Dehydrogenase 3 Substrates, Milena Ivkovic

USF Tampa Graduate Theses and Dissertations

N-Acylethanolamines (NAEs) are a class of fatty acid amides that act as important mammalian signaling molecules. N-Arachidonoylethanolamine is the best-studied representative and is one of the endogenous ligands for endocannabinoid receptors. NAEs play a role in the regulation of appetite, act as anti-inflammatory and analgesic agents, and are thought to have a neuroprotective function as well. They have been proposed to also serve as precursors to N-acylglycines (NAGs). N-Acylglycinals are likely to be intermediates between the NAEs and the NAGs. The sequential actions of a putative fatty alcohol dehydrogenase and a putative fatty aldehyde dehydrogenase are …

Blurring The Disconnect: [Inter]Positioning Place Within A Struggling Context, Eric Luttmann

USF Tampa Graduate Theses and Dissertations

Downtown Tampa, a struggling city core, will continue to struggle as it holds no true identity to its relationship with important surrounding context, as well as within itself. Evidence in the lack of inhabitable, urban spaces with the scale and comfort to support integral human activity on a day-to-day basis has resulted in the absence of a city center within downtown.

One lost opportunity for downtown is its disconnection with the University of Tampa, one that could result in an activated edge condition. As UT appears vertically congruous with downtown, it has no relationship as it is separated from it …

Measuring Culture Change As An Evaluation Indicator: Applying Cultural Consensus Analysis To Cultural Models Of Lymphatic Filariasis In Haiti, Kelly M. Simpson

USF Tampa Graduate Theses and Dissertations

Introduction: This project explores the links between shared cultural beliefs in the illness domain, specific to lymphatic filariasis, and a support group program implemented in three Haitian towns. The purpose is to introduce an innovative approach to evaluation, the cultural model evaluation technique (CM Evaluation), as well as gain an understanding of the shifting cognitive belief structure around the cultural domain of lymphatic filariasis in the Haitian setting as associated with a support group intervention.

Method: The sample population was comprised of 241 women across three sites in Haiti: Archaie, Cabaret, and La Plaine. Data were collected from longitudinal surveys …

The Drama Of Collaborative Creativity: A Rhetorical Analysis Of Hollywood Film Making-Of Documentaries, Robert M. González Jr.

USF Tampa Graduate Theses and Dissertations

Current creativity research is dominated by attention to the individual, with increasingly less attention paid to creativity in its context, in groups, and in filmmaking as a collaboratively creative enterprise. This study answers the research call to explore filmmaking as an exemplar for collaborative creativity. Utilizing the stories told on DVD extras on special edition releases of feature films, this study analyzes how collaborative creativity is storied. In turn, these stories reveal specific communication forms, practices, and strategies that enrich theoretical conceptions of collaborative creativity. Following dramatistic concepts elaborated by Kenneth Burke, this rhetorical analysis finds three emergent patterns of …

Scripting The Unscripted: Gender And Sexual Orientation In Strategy-Genre Reality Television, L Elizabeth Zollner

USF Tampa Graduate Theses and Dissertations

Since 2000, there has been an explosion of "reality," or unscripted, television shows in a variety of formats. The series in which new societies are created in isolation appeared almost immediately to be influenced by certain identity constructs, particularly gender and sexual orientation. Audiences came to these shows with definite expectations already in place. I intend in this study to determine why this is so and what those expectations are.

Survivor, the germinal presentation of this genre, has as its motto "Outwit, Outplay, Outlast." However, as the show has developed through many iterations, the ability to literally survive in …

Steady State And Theoretical Investigations Of Peptidylglycine Α-Amidating Monooxygenase (Pam), Edward W. Lowe

USF Tampa Graduate Theses and Dissertations

Approximately 50 percent of all known peptide hormones are post-translationally modified at their C-terminus. These peptide hormones are responsible for cellular functions critical to survival. Peptidylglycine alpha-amidating monooxygenase (PAM) is a bi-functional enzyme which catalyzes the conversion of peptide pro-hormones to peptide hormones.

PAM is the only known mammalian enzyme that catalyzes the necessary alpha-amidation to activate these peptide hormones. PAM has previously been found to perform N-dealkylation, as well as O-dealkylation. We report here that a novel chemistry for PAM, S-dealkylation, has now been shown. PAM was able to catalyzes the hydroxylation and subsequent dealkylation for a series …
