Hate Crimes And Jury Decision Making: An Exploratory Study Of Underlying Motivations Of How Mock Jurors Are Influenced By Extralegal Factors, Vimbai Mudimu

USF Tampa Graduate Theses and Dissertations

Statistics show that hate crimes continue to occur in United States, inciting fear and intimidation in minority communities (Petrosino, 1999; Torres, 1999; Saucier et al., 2006; Nolan et al., 2002; Jacobs & Potter, 1997). Although hate crime legislation has been passed, very little research has assessed what impact it has. This is particularly true for jury decision making. The aim of this study was to examine the main effects of type of crime (hate versus non-hate), offender-victim racial composition (African-American/Caucasian), and the interaction between these two variables on ratings of guilt likelihood, deserved punishment, and sentence recommendations after controlling for …

Net/Work: Composing The Posthuman Self, Julia L. Mason

USF Tampa Graduate Theses and Dissertations

The overall question this dissertation asks is: what does it mean to teach posthumans? To answer this question, this dissertation turns toward scholarship on the body in order to understand the virtual and material presence that students develop, it looks to online video gaming communities as alternative classrooms providing effective models of learning, and it investigates the circulation of service learning pedagogies within academic institutions as a marker of the persistence of humanistic values within the framework of a posthuman work environment.

The American university in general, and the humanities specifically, is struggling to make sense of its place in …

The Autoethnographic Call: Current Considerations And Possible Futures, Kendall Smith-Sullivan

USF Tampa Graduate Theses and Dissertations

This research examines the increase of personal narratives in the past several decades, particularly the autoethnographic approach. The project begins with a historical contextualization of personal writing and autoethnography in relation to the crisis of representation and other diverse socio-political shifts. One outcome of these cultural transitions was a proliferation of illness narratives, narrative therapy, therapeutic writing, and narrative health communication. Also included in this research are data from interviews with emerging autoethnographers and participant observation that occurred at the Third International Qualitative Inquiry Congress. The conference served as prism through which to view qualitative scholarship as a whole, as …

Determining The Quality And Impact Of An E-Mentoring Model On At-Risk Youth, Diane W. Culpepper

USF Tampa Graduate Theses and Dissertations

The purpose of this research was twofold. Since e-mentoring is relatively new, there have been very few studies that have explored the impact of an e-mentoring program on both the academic and psychological outcomes of its participants. In addition, there is little research on the quality of implementing, or what we will call the working quality, of an e-mentoring model. This study addressed both.

First, the study examined whether or not e-mentoring had an academic and psychological impact on 32 high school students who were at-risk of dropping out of school. The students were enrolled in a GED Exit Option …

USF Tampa Graduate Theses and Dissertations

I examined what brand new Ph.D.s in Communication experience when they start their first, entry-level, tenure-track assistant professor position at a new university. Through the lens of scocial construction, I review vocational and organizational socialization, individual agency by newcomers, academic socialization processes, and the concept of the academic career in the current climate of university change and transformation. Then, I present the method of research, including the population and sampling method, and rationales for utilizing a narrative approach, interactive interviewing, and autoethnographic writing. After presenting the participants' narratives, I revisit both within- and between-case issues, beginning with socialization from the …

Immunomodulation As A Potential Therapeutic Approach For Alzheimer’S Disease, William Veljko Nikolic

USF Tampa Graduate Theses and Dissertations

Alzheimer's disease (AD) is the most prevalent form of progressive dementia and is characterized by the accumulation of amyloid beta (Aß) peptide in the brain and in the cerebral vessels forming cerebral amyloid angiopathy (CAA). As previously reported, an active immunization strategy of mice with Aß_1-42 peptide results in decreased Th1 and increased Th2 cytokine responses as well as an effectively clearance of CNS Aß. This approach has also yielded favorable results for many patients, unfortunately, a small percentage of these study participants developed severe aseptic meningoencephalitis likely secondary to CNS invasion of activated T-cells. We have previously demonstrated …

The Relationship Between Individual Differences In Cognitive, Social And Personality Development And The Increase In Complexity Of Children’S Alcohol Expectancies, Nicole M. Bekman

USF Tampa Graduate Theses and Dissertations

The current study aimed to simultaneously examine cognitive, social and personality development in a cross-sectional sample of 3^rd, 4^th and 5^th grade children to explore the interplay among these processes and how they relate to changes in children's understanding of alcohol. To replicate previous work, this study comprehensively examined relative increases in types of expectancies as a function of development. Results demonstrated that children in higher grades held more positive, negative and sedating expectancies of alcohol and positive alcohol expectancies increased more than negative alcohol expectancies. Improved performance on cognitive measures were associated with positive alcohol …

Framing In Leadership Communication: Strategies, Breakdowns And Outcomes, Slaheddine Mnasri

USF Tampa Graduate Theses and Dissertations

This thesis examined framing practices used by leaders who participated in the Capacity Day 2007 event, which is organized by the World Bank Institute, as part of its Leadership Development Program. The study examined strategic uses of framing as a meaning-making tool. The framing strategies identified in this study were accomplished through the strategic use of language. Furthermore, the study recognized the implied negotiations of frames made by the skilled 'framers' and found that situations are continuously 'reframable'. Unsuccessful framing attempts were correlated with the contradictions between what was said and what was eventually understood. The positive outcomes that followed …

The Competencies For Community College Leaders: Community College Presidents' And Trustee Board Chairpersons' Perspectives, Anthony M. Hassan

USF Tampa Graduate Theses and Dissertations

At a time when strong leadership is needed to guide community colleges forward, a major crisis seems to be stirring (Eddy & VanDerLinden, 2006). According to some estimates, 45% of community college presidents will have retired by 2007 (Shults, 2001) and an even worse prediction offered by Weisman and Vaughan (2002) predict 79% of community college presidents will be retired by 2012. Echoing this view, Amey et al. (2002) assert that there is much work to be done in preparing the younger generations of community college leaders with skills and competencies necessary to meet this leadership challenge.

There were two …

Two Essays On Corporate Governance⎯Are Local Directors Better Monitors, And Directors Incentives And Earnings Management, Hong Wan

USF Tampa Graduate Theses and Dissertations

Previous literature have documented that the independent directors play a crucial goal in corporate governance but the research on the firm value and board independence remains inconclusive. In my dissertation, I examine the impact of independent directors' geographic proximity to corporate headquarters on the effectiveness of corporate boards and the motivations of board directors. Using a large sample of directors trading, I show that independent directors who live close to headquarters ("local director") earn higher abnormal returns on their trades than other directors, and that this advantage is stronger in small firms. Further, I find an inverse relationship between the …

Analysis Of The Role Of Bhlh/Pas Proteins In Aryl Hydrocarbon Receptor Signaling, Edward J. Dougherty

USF Tampa Graduate Theses and Dissertations

The aryl hydrocarbon receptor (AHR) is a basic helix-loop-helix PER/ARNT/SIM (bHLH-PAS) transcription factor that binds ligands typified by 2,3,7,8-tetracholordibenzo-p-dioxin, translocates to the nucleus, dimerizes with the aryl hydrocarbon nuclear translocator (ARNT) and associates with specific cis xenobiotic response elements to activate transcription of genes involved with xenobiotic metabolism. AHR-mediated signal transduction has been evaluated thoroughly in the C57BL/6J mouse model system. This model system, however, may not be the most accurate model for human comparisons as the AHR^b-1 allele carried by C57BL/6J contains a point mutation that prematurely truncates the receptor at 805 amino acids, while the AHR^{b-2 …}

Evaluation Of Contraflow Lanes For Hurricane Evacuation, Jason Collins

USF Tampa Graduate Theses and Dissertations

This dissertation evaluates contraflow during a hurricane evacuation for grade separated highways. Contraflow is the concept of reversing the typical direction of highway travel to provide more outbound roadway capacity. The State of Florida has spent more time and resources towards the planning and the designing of potential contraflow facilities than any other state in the country; however, contraflow has yet to be implemented (as of Summer 2008). This study determines if the additional capacity benefits of contraflow outweigh the logistical requirements of implementing contraflow. Five different alternatives of contraflow lane configurations were comparatively evaluated. The format of this study …

Corona Ion Deposition: A Novel Non-Contact Method For Drug And Gene Delivery To Living Systems, Niraj Ramachandran

USF Tampa Graduate Theses and Dissertations

Application of corona ions produced in air to B16F10 murine melanoma cells in vitro and in animal models resulted in the transport of molecular therapeutics across the cell membrane. This work presents the development of new methods for drug and gene delivery based upon similar principles as the traditional electrode driven membrane destabilization processes known as electroporation. This was achieved with non-contact corona ion deposition that temporarily increased the permeability of cell membranes.

Interaction of corona charge with biological cells was studied and their potential for molecular delivery was established. Molecular delivery was first demonstrated in vitro using tracer molecules …

USF Tampa Graduate Theses and Dissertations

This study examined how employees at a Florida medical facility felt regarding the upcoming change to a paperless system and whether a training program administered by the organization was effective in reducing anxiety, increasing understanding of the need for the change, increasing employee confidence using the new computer system, changing employee perceptions of the new system, and helping employees view the change as an organizational improvement. The results indicated that the training program marginally reduced anxiety, but did not significantly increase user confidence or understanding of the need for the change. While participants viewed the change as an organizational improvement, …

Isolation And Functional Characterization Of A Dioxin-Inducible Cyp1a Regulatory Region From Zebrafish (Danio Rerio), Gary T. Zeruth

USF Tampa Graduate Theses and Dissertations

Cytochrome P4501A1 (CYP1A1) is a phase I bio-transformation enzyme involved in the metabolism of xenobiotics via the oxygenation of polycyclic aromatic hydrocarbons (PAHs) including the carcinogen, benzo(a)pyrene. Induction of the CYP1A1 gene is regulated at the transcriptional level and is ligand dependent with the prototypical 2,3,7,8,-tetrachlorodibenzo-p-dioxin (TCDD) being the most potent known inducer of CYP1A1 transcription. This process is mediated by the AHR/ARNT signaling pathway whereby ligand binds AHR in the cytoplasm allowing its translocation to the nucleus where it binds with its hertrodimerization partner, ARNT and subsequently binds DNA at cognate binding sites termed xenobiotic …

Black Beauty As Antebellum Slave Narrative, Bonnie L. Blossom

USF Tampa Graduate Theses and Dissertations

Published in November 1877, Black Beauty is one of the most popular and enduring works of the nineteenth and twentieth centuries. The book, in which the eponymous narrator relates his life's story, sold well following its publication in England and in the United States; by 1985, sales were estimated at over forty million. While usually regarded as entertaining, Black Beauty has a strong crusading purpose: Anna Sewell herself said she wrote to improve the treatment of horses.

This study springs from an intuitive notion. While reading the 1845 Narrative of the Life of Frederick Douglass, I could not shake …

Role Of Culture In Economic Development: China Study Of China And Latin America, Amira Fellner

USF Tampa Graduate Theses and Dissertations

The purpose of my thesis is to demonstrate the economic development of China and Latin America. My reason for choosing these two regions for my study is because they are both Third World Nations. My intention on writing this thesis is to prove that culture and the informal business networks of China are the major forces of what is driving the Chinese economy ahead of Latin America.

I will explain how the definition of culture ties in with the economic society of both regions. In writing about culture, I will attempt to explain if there really is a difference between …

Creative City And Fields Of Cultural Production: Ethnographic Perspectives Of “The Arts” In Tampa, James Kuzin

Stimulated by the economic theories of Richard Florida (2005), the City of Tampa established the Office of Creative Industries (OCI) to oversee efforts to strengthen the presence and visibility of "the arts." This thesis presents ethnographic research focused on practices, and perspectives among members of the OCI's service population. From July 2006 to July 2007, I conducted fieldwork among a diverse group of stakeholders possessing a unique connection to the aims of the OCI. The central problem addressed in this research looks at the degree to which cultural change occurs from participatory, grass-roots initiatives, rather than ones emanating from "the …

Capitalism, Consumerism, And Individualism: Investigating The Rhetoric Of The Secret, Carolina Fernandez

USF Tampa Graduate Theses and Dissertations

I am investigating a New Age spiritual movement called the Law of Attraction that has been the source of recent media attention due to the recent publication of a self-help book called The Secret. The book investigates this phenomenon, which is a theory that takes positive thinking to the extreme. The theory states that reality can be literally manifested through one's thoughts. I am interested in this trend because it supports consumerist values, entrepreneurship, and self-actualization while using socialist rhetoric to promote capitalist values. I am also interested in the implications that this rhetoric holds for women and marginalized groups. …

An Evaluation Of Conduit Conceptualizations And Model Performance, Melissa Estelle Hill

USF Tampa Graduate Theses and Dissertations

The karst research community has known that traditional numerical groundwater flow codes ignore the non-Darcian, dual-permeability components of flow that can occur in karst aquifers. In this study, the potential limitations of using such tools are quantified by evaluating the relative performances of 3 groundwater flow models at a test-site near Weeki Wachee, Florida, in the dual-permeability Upper Floridan aquifer. MODFLOW-2005 and MODFLOW-2005 Conduit Flow Process (CFP), a Darcian/non-Darcian, dual-permeability groundwater flow code recently developed by the U.S. Geological Survey, are used in this study.

A monitoring program consisting of discharge measurements and high frequency data from 2 springs and …

The Spatial Distribution Of Geoprivacy Concerns In Florida: A County Level Analysis, Joshua W. House

USF Tampa Graduate Theses and Dissertations

Certain types of spatial data maintained and distributed by counties at taxpayer expense can be used with powerful mapping and analysis software, called Geographic Information Systems (GIS), to compromise an indvidual's locational privacy. The kind of privacy at threat here is referred to as geoprivacy, which is concerned with the rights to prevent disclosure of the location of one's home, workplace, or daily activities. While the availability of accessible and accurate geospatial data has increased geoprivacy concerns in recent years, this threat remains virtually unknown to the general public.

Although previous research has explored various components of the geoprivacy …

Results found that players feel their organizations disproportionately help some players achieve success over others and withhold information. As players, they felt they have a limited voice regarding the direction of their careers. Despite a difficult working environment, the players' desire to achieve success and …

¿Femenino O Feminista? Mensajes Para El Presente De Tres Escritoras Hispanas Del Siglo Xix, Beatriz Muller-Marqués

USF Tampa Graduate Theses and Dissertations

This thesis is a comparative study of Spanish and Latin-American women writers of the 19^th century. This work shows how these writers, even though distanced by geographical and/or generational gaps, as well as cultural differences, share, not only the Spanish language but also common interests, themes and discursive characteristics. The investigation focuses on the work of three renowned writers: Cecilia Böhl de Faber from Spain, and Gertrudis Gómez de Avellaneda and Clorinda Matto de Turner, from Latin-America. The three of them revolutionized in different ways the feminine perception in the nineteenth century.

The introductory chapter provides a general overview …

Impact Of West Nile Virus On The Natural History Of St. Louis Encephalitis Virus In Florida, Christy L. Ottendorfer

USF Tampa Graduate Theses and Dissertations

The emergence of West Nile virus (WNV) has raised important questions about the capacity of the public health infrastructure to implement surveillance and control programs for WNV and other emerging or re-emerging arboviruses in the United States. Florida's mild climate supports year round enzootic transmission of WNV, St. Louis encephalitis virus (SLEV), and Eastern Equine Encephalitis virus (EEEV). It is unknown what effect the establishment of WNV (in 2001) will have on SLEV transmission in Florida, where these closely related flaviviruses share amplifying hosts, habitats, and vectors.

An Arbovirus Isolation Network was formed to obtain and characterize arbovirus strains collected …

Advances In Magnetic Resonance Electrical Impedance Mammography, Nataliya Kovalchuk

USF Tampa Graduate Theses and Dissertations

Magnetic Resonance Electrical Impedance Mammography (MREIM) is a new imaging technique under development by Wollin Ventures, Inc. in conjunction with the H. Lee Moffitt Cancer Center & Research Institute. MREIM addresses the problem of low specificity of magnetic resonance mammography and high false-positive rates, which lead to unnecessary biopsies. Because cancerous tissue has a higher electrical conductivity than benign tissue, it may serve as a biomarker for differentiation between malignant and benign lesions. The MREIM principle is based on measuring both magnetic resonance and electric properties of the breast by adding a quasi-steady-state electric field to the standard magnetic resonance …

Brca1 185delag Mutant Protein, Brat, Amplifies Caspase-Mediated Apoptosis And Maspin Expression In Ovarian Cells, Joshua D. O'Donnell

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is a deadly disease that kills an estimated 15,000 women annually in the United States. It is estimated that approximately 10% of ovarian cancers are due to familial inheritance. The most commonly mutated genes in familial ovarian cancer are BRCA1 and BRCA2. It has been reported that cells carrying the BRCA1 185delAG mutation undergo an enhanced caspase-3 mediated apoptotic response. Here, we report on the transfection of cDNA coding for the putative truncated protein product of the BRCA1 185delAG mutant gene into BRCA1 wild-type human immortalized ovarian surface epithelial (IOSE) cells and ovarian cancer cells. Cells transfected …

Surface And Interface Magnetism In Nanostructures And Thin Films, Natalie A. Frey

USF Tampa Graduate Theses and Dissertations

Nanostructured systems composed of two or more technologically important materials are useful for device applications and intriguing for the new fundamental physics they may display. Magnetism at the nanoscale is dominated by size and surface effects which combined with other media lead to new spin dynamics and interfacial coupling phenomena. These new properties may prove to be useful for optimizing sensors and devices, increasing storage density for magnetic media, as well as for biomedical applications such as drug delivery, MRI contrast enhancement, and hyperthermia treatment for cancer. In this project we have examined the surface and interface magnetism of composite …
