An Investigation Of A Dual-Factor Model Of Mental Health And Related Physical Health Outcomes Among Early Adolescents, Emily J. Shaffer Jan 2006

An Investigation Of A Dual-Factor Model Of Mental Health And Related Physical Health Outcomes Among Early Adolescents, Emily J. Shaffer

USF Tampa Graduate Theses and Dissertations

This study investigated the mental and physical health of early adolescents (n = 339) using a dual-factor model of mental health. When employing a dual-factor model, mental well-being is not simply assumed from the absence of negative indicators of mental health (psychopathology). Rather, assessments of positive indicators of mental health (subjective well-being) are used to determine one's level of mental wellness. The current study tested the existence of a dual-factor model of mental health by examining the separability of participants' reports of subjective well-being and psychopathology. Specifically, the researcher hypothesized that the assessment of both of these constructs would result …

The Social Construction Of School Refusal: An Exploratory Study Of School Personnel’S Perceptions, Anna Marie Torrens Salemi

USF Tampa Graduate Theses and Dissertations

Despite a multi-disciplinary, international literature, little research has drawn attention to the phenomenon of school refusal within the school. Most research on school refusal follows a positivist paradigm, focusing on the student, instead of examining the role of schools. Using a qualitative design and a social constructionist framework, this study explored how school personnel perceive school refusal, focusing on the social interactions, processes, and perceptions that construct their understanding. The study was conducted in a large school district in the Southeastern United States.Semi-structured in-depth interviews were conducted with school personnel at the middle school (N=42), high school (N=40), and district …

Regulation Of Transcription And Analysis Of Drug Targets In Lymphoma And Myeloma Cells, Noah L. Silverman

USF Tampa Graduate Theses and Dissertations

The passage of two major hurricanes across southwest Florida (Category 5, Labor Day Hurricane of 1935; Category 4, Hurricane Donna 1960) resulted in fragmentation of mangrove forest at Big Sable Creek, Everglades National Park. Over time forest fragmentation led to forest loss and patchy conversion to unvegetated mudflats. My goal was to determine the consequence of forest fragmentation on nekton (i.e., fish and decapod crustaceans) inhabiting the intertidal zone. I used block nets across intertidal rivulets to compare nekton leaving replicate forest and unvegetated mudflat sites from October, 2002 through April 2004. Overall nekton density (individuals per 100 m3) was …

The Causal Effect Of Alcohol Consumption On Employment Status, Chanvuth Sangchai Jan 2006

The Causal Effect Of Alcohol Consumption On Employment Status, Chanvuth Sangchai

USF Tampa Graduate Theses and Dissertations

Alcohol consumption may affect labor market outcomes directly through a reduction in productivity and indirectly through human capital accumulation. However, empirical results from previous studies in the economics literature are mixed and inconclusive. While some researchers found negative effects of alcohol use on labor market outcomes, quite a few studies found either positive or insignificant effects. The purpose of this dissertation is to estimate causal effects of alcohol consumption on employment status. It uses three data sets previously unexploited for this purpose and attempts to eliminate any potential estimation problems from previous studies. The results show that previous problematic heavy …

Heme Biosynthesis: Structure–Activity Studies Of Murine Ferrochelatase, Zhen Shi Jan 2006

Heme Biosynthesis: Structure–Activity Studies Of Murine Ferrochelatase, Zhen Shi

USF Tampa Graduate Theses and Dissertations

Ferrochelatase catalyzes the terminal step of heme biosynthesis by inserting ferrous iron into protoporphyrin IX. The current study is aimed at understanding the structural basis of porphyrin binding and distortion in ferrochelatase-catalyzed reaction by functional analysis of a highly conserved active site loop motif. The loop was shown to contact bound porphyrin based on crystallographic and molecular modelling observations, and its role in murine ferrochelatase was assessed by random mutagenesis and steady-state kinetic analysis. To overcome the limitations of conventional kinetic assay methods for ferrochelatase, a continuous assay was developed by monitoring porphyrin fluorescence decrease using natural substrates ferrous iron …

Geochemical Signatures In The Coral Montastraea: Modern And Mid-Holocene Perspectives, Jennifer Mae Smith Jan 2006

Geochemical Signatures In The Coral Montastraea: Modern And Mid-Holocene Perspectives, Jennifer Mae Smith

USF Tampa Graduate Theses and Dissertations

In the first phase of this project, four decades of monthly resolved geochemical variations from two massive heads of Montastraea were used to explore the reproducibility of the geochemical signal in these two corals from Looe Key, Florida. The coral d18O and d13C records of the two corals have statistically indistinguishable mean values, which is not the case for the coral Sr/Ca records implying that nonenvironmental factors are influencing coral Sr/Ca. Calibration equations relating coral geochemistry variations to environmental variations at Looe Key are different from previously published equations for Montastraea. These calibration differences are not related to growth-related kinetic …

Selling St. Petersburg: John Lodwick And The Promotion Of A Florida Paradise, Nevin D. Sitler

USF Tampa Graduate Theses and Dissertations

For over a century Florida's Tampa Bay area has been extolled for its abundant seashores and moderate climate. The success of early twentieth-century St. Petersburg as a tourist destination was due to a consistent method of self-promotion highlighting the natural and physical features of peninsular Pinellas County. Warmed by balmy Tampa Bay breezes, St. Petersburg had been dubbed the "Health City." This tiny 1890 coastal town of less than three hundred inhabitants, now blessed with a slogan, new train tracks, and a railway pier, was an ideal setting for tourism. By 1902, boosters declared St. Petersburg a city second to …

A Novel Air Sampling And Analytical Method For Determination Of Airborne Bronopol, John Charles Smyth Jan 2006

A Novel Air Sampling And Analytical Method For Determination Of Airborne Bronopol, John Charles Smyth

USF Tampa Graduate Theses and Dissertations

Bronopol has been used as a preservative in drugs and cosmetics since 1964. Bronopol has low dermal irritancy at levels commonly used in cosmetics and pharmaceuticals but it is significantly irritating at higher concentrations. Laboratory testing of bronopol indicates a low potential for dermal sensitization; however, a number of case reports demonstrate human allergenic reactions. No reports were identified on the allergenic properties of bronopol for the inhalation route of exposure. In 1983 approximately 5,200 people in the United States were occupationally exposed to bronopol. Current novel uses of bronopol include mold remediation and the sanitizing of ventilation system components. …

Multiple Voices And The Single Individual: Kierkegaard’S Concept Of Irony As A Tool For Reading The Great Gatsby, The Sun Also Rises, Mrs. Dalloway, And Ulysses, Thomas P. Smith

USF Tampa Graduate Theses and Dissertations

The central issue in the works of Danish philosopher and religious thinker Soren Kierkegaard (1813-1855) takes the form of a question: "What does it mean to become a Christian?" However, Kierkegaard's ideas exerted influence well beyond Christian circles and have been important to many notable philosophical and literary figures, some of whom chose not to concern themselves primarily with this question (Sartre, Camus, Heidegger, Buber), and some of whom did choose to concern themselves primarily with this question (Tillich, Bonhoeffer, Berdyaev, Marcel). Even though Kierkegaard died in relative obscurity, thanks to posthumous translation of his works into German and to …

Advancements In Rapid Load Test Data Regression, Michael Jeffrey Stokes Jan 2006

Advancements In Rapid Load Test Data Regression, Michael Jeffrey Stokes

USF Tampa Graduate Theses and Dissertations

Rate-dependent effects introduced during rapid and/or dynamic events have typically been oversimplified to compensate for deficiencies in present analyses. As load test results are generally considered as the basis of performance from which foundations can be designed, it is imperative that the analyzed load test data be as accurate as possible. In an attempt to progress the state of load test data regression, this dissertation addresses two common assumptions made during the regression process: (1) the statnamic damping coefficient is constant throughout the entire load test and (2) the concrete stress-strain relationship is linear-elastic. Also presented is a case study …
