The participants answered questions that explored education, success, identity construction, ethnicity and sport. Archival data was also reviewed framing the discussion on football in Florida, links between education and sport participation and African American male academic achievement. While many perspectives varied, there were collective …

Down, But Not Out: An Ethnographic Study Of Women Who Struggled With And Overcame Methamphetamine Addiction, Jodi Nettleton

USF Tampa Graduate Theses and Dissertations

Women suffer methamphetamine (meth) addiction at a rate much higher than rates for addiction to other drugs. Female meth users are susceptible and predisposed to gender-related risks: high rates of unprotected vaginal and anal sex, sex-work, and sexual coercion. Precursors for addiction (e.g., abuse, body dysphasia) put females in a difficult position for recovery and highlight the need for gender-specific research and treatment.

Methamphetamine (a synthetically derived stimulant) creates psychological and physical dependency that affects every neuron of the brain and damages the body immediately. Women ingest meth for initial effects that allay social pressures: feeling euphoric, connecting with others …

Antecedents And Consequences Of Channel Alienation: An Empirical Investigation Within Franchised Channels Of Distribution, Ivan Lapuka

USF Tampa Graduate Theses and Dissertations

Investigating an important overlooked phase of interorganizational relationship evolution, which is currently hypothesized to progress through five stages of awareness, exploration, expansion, commitment, and dissolution, this dissertation proposes that in the long road between commitment and dissolution, the quintessential interfirm relationship is likely to be characterized by aprolonged period of relationship alienation, which then becomes the immediate precursor to the dissolution stage.

The dissertation utilizes social learning theory, behavior constraint theory, and alienation theory to explain apathetic behaviors of franchisees. The principal proposition is that certain characteristics of the franchise system’s operating environment inadvertently condition franchisee estrangement and failure, and …

Discovery Of Novel Viruses From Animals, Plants, And Insect Vectors Using Viral Metagenomics, Terry Fei Fan Ng

USF Tampa Graduate Theses and Dissertations

Understanding emerging viruses is critical for disease monitoring and prediction; however, surveys of novel viruses are hindered by the lack of a universal assay for viruses. Viral metagenomics, consisting of viral particle purification and shotgun sequencing, is a powerful technique for discovering viruses in a wide variety of sample types. However, current protocols are not effective on tissue samples (e.g., lungs, livers and tumors), where they are hindered by the high amount of host nucleic acids which limits the percentage of sequences that originate from viruses. In this dissertation, a modified viral metagenomics protocol was developed and utilized to effectively …

Corrole Synthesis And Catalytic Applications Toward Cobalt(Iii)-Catalyzed Epoxidation, N-H Insertion, And Cyclopropanation, Chung Sik Kim

USF Tampa Graduate Theses and Dissertations

A variety of bromocorroles, useful precusors for Pd-based cross coupling, were sucessfully synthesized in moderate to good yields. Chiral corroles were also synthesized through use of chiral amides in the aforementioned cross coupling reactions. Cobalt complexes bearing π-acceptor (CNtBu) and σ-donor (PPh3) ligands were also prepared in excellent yields. In this dissertation, cobalt (III) corrole complexes were applied to three different reaction areas: epoxidation, N-H insertion, and cyclopropanation. Cobalt(III) corroles were found to be efficient catalysts for epoxidation reactions. The epoxidation reactions can be carried out using ethyl phenyldiazoacetate, an acceptor/donor diazo compound, as a carbenoid precusor.The reaction provided highly …

Design And Synthesis Of Beta-Hairpin Peptidomimetics For Modulating Integrin Mediated Cell Adhesion, Abeta Fibrillogenesis And P53-Mdm2 Protein-Protein Interactions, Priyesh Jain

USF Tampa Graduate Theses and Dissertations

Inhibiting therapeutically important protein-protein interactions has been a tremendous challenge for medicinal chemists. The folded 3D structures of peptides and proteins, mainly comprise secondary structural elements i.e α-helices and β-sheet have created an opportunity to design small molecules and peptidomimetic inhibitors of protein-protein interaction (PPI). Hence, information about the formation and stabilization of these secondary structures is vital for designing future drugs. In this dissertation, several cyclic beta-hairpin peptidomimetics that mimic the recognition surface have been designed and synthesized as inhibitors for different targets such as integrin mediated extracellular matrix -cell adhesion in multiple myeloma, p53-MDM2 PPI, amyloid beta fibrillogenesis …

Dna Methylation And Its Association With Prenatal Exposures And Pregnancy Outcomes, Jennifer Straughen

USF Tampa Graduate Theses and Dissertations

Altered DNA methylation may lead to suboptimal fetal programming, increasing the risk of adverse pregnancy outcomes such as small for gestational age (SGA); however, few studies have examined the associations between DNA methylation, prenatal exposures, and fetal outcomes. Cross-sectional data from a larger, ongoing study were used to assess the impact of prenatal smoking on gene specific methylation of umbilical cord blood derived DNA and to investigate the association between gene-specific methylation and risk of SGA. The association between gene-specific DNA methylation and birthweight was also assessed. Maternal and infant covariates were abstracted from medical records, cigarette smoke exposure was …

Advanced Signal Processing Techniques For Single Trial Electroencephalography Signal Classification For Brain Computer Interface Applications, Kun Li

USF Tampa Graduate Theses and Dissertations

Brain Computer Interface (BCI) is a direct communication channel between brain and computer. It allows the users to control the environment without the need to control muscle activity [1-2]. P300-Speller is a well known and widely used BCI system that was developed by Farwell and Donchin in 1988 [3]. The accuracy level of the P300-BCI Speller as measured by the percent of communicated characters correctly identified by the system depends on the ability to detect the P300 event related potential (ERP) component among the ongoing electroencephalography (EEG) signal. Different techniques have been tested to reduce the number of trials needed …

Evaluation Of Common Inherited Variants In Mitochondrial-Related And Microrna-Related Genes As Novel Risk Factors For Ovarian Cancer, Jennifer Permuth Wey

USF Tampa Graduate Theses and Dissertations

Epithelial ovarian cancer (EOC) is a leading cause of morbidity and mortality among women in the United States, and the etiology is incompletely understood. Common, low penetrant genetic variants such as single nucleotide polymorphisms (SNPs) likely contribute to a significant proportion of EOC. We examined whether SNPs in two understudied yet biologically important types of genes, mitochondrial-related and miRNA-related genes, may contribute to EOC susceptibility using data from a large, homogeneous study population of 1,815 EOC cases and 1,900 controls (frequency-matched on age-group and race/ethnicity) genotyped through stage 1 of an ongoing genome-wide association study. Inter-individual variation in genes involved …

Epidemiological Study Of Contributing Factors In The Development Of Peptic Ulcer And Gastric Cancer Initiated By Helicobacter Pylori Infection In India, Rahul Suresh Mhaskar

USF Tampa Graduate Theses and Dissertations

Background: Helicobacter pylori (H. pylori) infection is a significant risk factor for peptic ulcer (PU) and gastric cancer (GC). Apart from the virulent CagA genotype of H. pylori environmental and dietary factors influence disease outcomes. There have been no studies addressing these factors in Western India. Hence, we conducted a case control study enrolling PU, GC patients and controls at Pune, India.

Methods: Risk factors for PU and H. pylori infection were assessed in participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. To understand treatment effect, we followed 100 H. pylori positive patients.

Results: We …

Aspects Of The Life History Of The Snowy Grouper, Epinephelus Niveatus, In The Gulf Of Mexico, Kelley Kowal

USF Tampa Graduate Theses and Dissertations

Knowledge of many life history parameters are essential to properly assess and manage fish species. Although the snowy grouper, Epinephelus niveatus, is a commercially valuable fish, which is harvested throughout the Gulf of Mexico, little is known about its age, growth, and reproduction from this region. In this study, snowy grouper from the northern and eastern regions of the Gulf of Mexico were examined primarily using commercially-derived samples that were collected between 1984 and 2004. A total of 1,200 snowy grouper with fork lengths between 242 and 1,190 mm were collected. Sectioned saggital otoliths were used to determine the age …

Genetic History Of An Archaic Hominin Group From Denisova Cave In Siberia, David Reich, Richard E. Green, Martin Kircher

KIP Articles

Using DNA extracted from a finger bone found in Denisova Cave in southern Siberia, we have sequenced the genome of an archaic hominin to about 1.9-fold coverage. This individual is from a group that shares a common origin with Neanderthals. This population was not involved in the putative gene flow from Neanderthals into Eurasians; however, the data suggest that it contributed 4–6% of its genetic material to the genomes of present-day Melanesians. We designate this hominin population ‘Denisovans’ and suggest that it may have been widespread in Asia during the Late Pleistocene epoch. A tooth found in Denisova Cave carries …

The Nature And Intersection Of Partisanship And Ideology, Charles Jolm Manter

USF St. Petersburg campus Honors Program Theses (Undergraduate)

My first encounter of the political kind occurred in 1992, when a kindergarten classmate asked me who my parents voted for. Based on some dinner conversations, which went mostly over my head, I knew they voted for Bill Clinton. He told me his parents voted for Bush. At that time, a "party" was something associated only with birthdays and I was unaware of the existence of the word "ideology." I understood, however, that politics entails conflict. His parents voted for someone different than my parents voted for: his parents lost and my parents won. Over the next several years, my …

The Roles Of Elevated Bcl-2 In Ovarian Cancer, Nicole Shree Anderson

USF Tampa Graduate Theses and Dissertations

Ovarian cancer (OC) is the second most common gynecologic cancer; however it is responsible for the most gynecologic cancer-related deaths. Apoptosis evasion is an important mechanism in OC tumorigenesis, and the prototypic anti-apoptotic protein, B-cell lymphoma 2 (Bcl-2), is often overexpressed in OC tumors. Gaining a better understanding of the mechanism(s) behind Bcl-2 overexpression and potential extra-anti-apoptotic functions of Bcl-2 could elucidate the importance of elevated Bcl-2 in OC. In the current study, I show through immunohistochemical analysis of normal, benign, and OC tissue sections, that both epithelial and stromal Bcl-2 expression decreases with OC progression. However, the number of …

1,2,3,4-Tetrahydroacridones As Potential Inhibitors Of Atovaquone-Resistant And Atovaquone- Susceptible P. Falciparum Isolates Tm90-C2b And W2, Lisa Luong

Outstanding Honors Theses

Malaria is one of the most significant parasitic diseases affecting mankind today, exceeding 200 million annual cases worldwide1. This disease has been a serious issue due to developed resistance to commonly available antimalarial drugs including atovaquone and artemisinin2, the most relevant modern treatment (figure 1.1). This project focuses on the preparation of 1,2,3,4- tetrahydroacridones (figure 1.2) that can be tested for their activity against P. falciparum isolates TM90-C2B (an atovaquone-resistant parasitic strain) and W2 (an atovaquone-susceptible parasite). In the past, studies have shown that endochins (4(1H)-quinolones) 3 and acridines (figure 1.1) have been found to exhibit antimalarial activity4. The research …

Deglacial Abrupt Climate Change In The Atlantic Warm Pool: A Gulf Of Mexico Perspective, Carlie Williams, Benjamin P. Flower, David W. Hastings, Thomas P. Guilderson, Kelly A. Quinn, Ethan A. Goddard

Marine Science Faculty Publications

During the last deglaciation, Greenland ice core and North Atlantic sediment records exhibit multiple abrupt climate events including the Younger Dryas cold episode (12.9-11.7 ka). However, evidence for the presence of the Younger Dryas in the Gulf of Mexico (GOM) and the relationship between GOM sea surface temperature (SST) and high-latitude climate change is less clear. We present new Mg/Ca-SST records from two varieties of the planktonic foraminifer Globigerinoides ruber (white and pink) to assess northern GOM SST history from approximately 18.4-10.8 ka. Thirty-five accelerator mass spectrometry (AMS) C-14 dates from Orca Basin core MD02-2550 provide excellent age control and …

A Multi-Level Study Investigating The Impact Of Workplace Civility Climate On Incivility And Employee Well-Being, Raymond Charles Ottinot

USF Tampa Graduate Theses and Dissertations

This study used Zohar‟s (2000) multi-level model of climate to examine the extent to which shared perceptions of workplace civility climate relate to teacher job satisfaction, affective commitment, and counterproductive work behaviors (CWB-abuse) towards other teachers. Workplace civility climate is defined as employee perceptions of how management uses policies, procedures, and practices to maintain a civil workplace. An online-survey was used to assess a cross-sectional sample of K-12 teachers (N = 2222) nested in 207 schools in a large US school district. There was adequate agreement among teacher perceptions of school civility climate for aggregation and between-group variance of civility …

The Pragmatic Influences On Thou And Ye In Some Middle English Romances, Aislinn Meyer

Outstanding Honors Theses

The standard explanation of the semantics of power and solidarity for second person Middle English pronoun choice, advanced by Roger Brown and Albert Gilman and accepted by many Middle English scholars since, has proven insufficient to explain many choices between thou and ye that fictional characters make. This paper applies the discourse theories of pragmatics and politeness, developed by Penelope Brown and Stephen C. Levinson, to the relatively untouched data set of non-Chaucerian romances in order to account for some of those anomalies. By examining the pronouns of address in Floris and Blancheflour, Havelok the Dane, Ywain and Gawain, …

Coupling Of Surge And Waves For An Ivan-Like Hurricane Impacting The Tampa Bay, Florida Region, Yong Huang, Robert H. Weisberg, Lianyuan Zheng

Marine Science Faculty Publications

The interactions between waves and storm surge are investigated using an unstructured grid, coupled wave‐surge model forced by a hypothetical Ivan‐like hurricane impacting the Tampa Bay, Florida region. The waves derived from the unstructured version of the third‐generation wave model simulating waves nearshore. The surge derives from the unstructured Finite‐Volume Coastal Ocean Model, to which wave‐induced forces (based on radiation stress theory) are added to the traditional forces by winds and atmospheric pressure. Dependent upon complex bathymetry and geometry, the wave‐induced forces result in an additional 0.3∼0.5 m of surge relative to an uncoupled, surge‐only simulation, and the increase in …
