Loving Loving? Problematizing Pedagogies Of Care And Chéla Sandoval’S Love As A Hermeneutic, Allison Brimmer

USF Tampa Graduate Theses and Dissertations

My thesis project is an argument for and an investigation into the complex dynamics of what I term a critical, feminist, anti-racist pedagogy. Drawing from scholarly work in the fields of feminist theory, cultural studies, whiteness studies, and rhetoric and composition, in what follows I argue for a “blurring” of the traditional reason-emotion split that, I believe, continues to stifle learners in today’s U.S. educational system. I then offer a pedagogical theory that rejects or “blurs” this split, acknowledges and examines the affective realm, and is fueled by the more holistic notion and theory of “love as a hermeneutic” put …

Reconstructing Women's Identities: The Phenomenon Of Cosmetic Surgery In The United States, Cara L. Okopny

USF Tampa Graduate Theses and Dissertations

The popularity of cosmetic surgery in the U.S. has increased dramatically over the last ten years - particularly for women, who make up the largest group of cosmetic surgery consumers. Cosmetic surgery can include relatively simple procedures such as permanent hair removal or Botox to more complicated procedures like breast augmentations and face-lifts. The rise in popularity of cosmetic surgery exalts only one kind of beauty and excludes many women from ever attaining this ideal, so while women may feel empowered, surgery acts as a form of assimilation, because the act of cosmetic surgery reifies an exclusionary beauty norm. With …

Supercritical Carbon Dioxide Aided Preparation Of Nickel Oxide/Alumina Aerogel Catalyst, Haitao Li

USF Tampa Graduate Theses and Dissertations

The strength, thermal stability, pore structure and morphology are keys to success for wider deployment of aerogels. Furthermore, co or subsequent functionalization of the surfaces are equally, if not more important. This study addresses these issues through a new method. The path involves successful use of surfactant templating, supercritical extraction and drying, and supercritical fluid aided functionalization of the surface. Alumina support and alumina supported nickel catalyst particles are used to evaluate the approach. Initially thermally stable surfactant alumina was synthesized. The surfactant template was removed completely with the aid of a supercritical solvent mixture. Surfactant-templated alumina aerogel showed remarkable …

The Analysis Of Dielectric Loss In Co-Planar Waveguide Structures Using Generalized Transverse Resonance, James William Culver

USF Tampa Graduate Theses and Dissertations

There are several methods for the full-wave characterization of waveguide discontinuities; Finite Element Method (FEM), Finite Difference Technique (FDT), and Method of Moments (MoM) are popular. However, these methods are not easily applied when studying the ‘modal anatomy’ of a discontinuity. Other full-wave techniques are better suited. This dissertation discusses the formulation of a technique known as Generalized Transverse Resonance (GTR), which is a subset of Method of Moments. Generalized Transverse Resonance is a hybrid method combining the Transverse Resonance Method (TRM) with the Mode Matching Technique (MMT).

The understanding of the generalized transverse resonance method starts with a discussion …

Reconfigurable Wireless Sensor Platform For Training And Research In Networked Embedded Systems, Oscar V. Gonzalez

USF Tampa Graduate Theses and Dissertations

Ever since the University of California, Berkeley released the first commercial Wireless Sensor Network, (WSN), "mote", applications that employ the WSN technology have increased many fold. There are many kinds of prototypes and architectures for WSNs that are being developed by major communication companies. Due to the lack of a common standard for different physical and MAC layer protocols, interoperability among the wireless systems is constrained. Additionally, remote sensing capability, reconfigurability and interoperability have not yet been designed. In the current platforms hardware upgrading has to be performed on-site by replacing the old sensors with new ones. This procedure increases …

The Effect Of Perceived Entitativity On Implicit Image Transfer In Multiple Sponsorships, Francoì?Is Anthony Carrillat

USF Tampa Graduate Theses and Dissertations

This dissertation proposes that in the case of multiple sponsorships (i.e., brands sponsoring concomitantly the same event), the group constituted by the sponsoring brands and the sponsored event will be perceived as an entity; a phenomenon that Campbell (1958) called entitativity. The extent to which a group of brands and a sponsored event is seen as being entitative will result in stereotypic processing of the group members (Brewer and Harasty 1996). Information about an entitative group is abstracted and used to form judgments about every group member (McConnell, Sherman, and Hamilton 1997). Characteristics tied to one brand or to the …

Relationship Of Waste Characteristics To The Formation Of Mineral Deposits In Leachate Collection Systems, Antonio J. Cardoso

USF Tampa Graduate Theses and Dissertations

Landfill leachate is generated as a result of reactions between water percolating through the landfill and wastes. Under normal conditions leachate is found at the bottom of landfills and from there, its movement can be controlled with collection systems to be treated, discharged, or recirculated. Landfill leachate collection systems are positioned above the liner and are designed to collect liquid under gravitational flow for the entire active, closure, and post-closure periods. Clogging of any portion of the system can lead to higher hydraulic heads and increase the potential for leakage through the liner.

To reduce the quantity of municipal solid …

Commensal Fecal Bacteria: Population Biology, Diversity, And Usefulness As Indicator Organisms In Reclaimed Water, Vasanta Lakshmi Chivukula

USF Tampa Graduate Theses and Dissertations

Water treatment facilities have been relying on indicator bacteria to assess the quality of water for decades. The purpose of this group of studies is to investigate the predictive capabilities of conventional and alternative indicators for pathogenic microorganisms in disinfection processes and treated wastewater effluents. In addition, the possibility that diversity of indicator bacteria, as well as overall bacterial diversity, correlate with fecal contamination in water bodies has been investigated. Indicator organisms (total coliforms, fecal coliforms, enterococci, C. perfringens, and coliphages) as well as pathogens (enteroviruses, Giardia, and Cryptosporidium) were enumerated from six wastewater treatment facilities at …

Promoting And Preventing Alzheimer’S Disease In A Transgenic Mouse Model: Apolipoprotein E And Environmental Enrichment, David Antonio Costa

USF Tampa Graduate Theses and Dissertations

Besides age, inheritance of the apoE-ε4 allele is the main risk factor for late-onset AD. To determine the role of apoE in amyloid deposition, we studied mice expressing both mutant human amyloid ß-protein precursor (APP) and presenilin 1 (PS1) that were either normal or knocked-out for apoE. By 7 months, amorphous Aß deposition developed equally in both lines, indicating that Aß alone is sufficient for deposition to occur. In contrast, filamentous amyloid deposition was catalyzed at least 3000 fold by apoE. Electron micrographs further illustrate the filamentous nature of these plaques. These results and other, behavioral, data indicate that the …

The Power Of The Spoken Word: Literature In The American Mass Media Of The 1990s, Codrina Cozma

USF Tampa Graduate Theses and Dissertations

The 1990s saw a climax of literature representations in what Ong called the secondary orality, particularly in film, television, and radio; for instance, the film industry produced a number of adaptations of novels that had been accepted into the American literary canon, while television and radio marketed literature through book clubs and literary shows. All these literary productions mediated through film, radio, and television are referred to in this study as mediatized literature.

The argument of this dissertation is that 1990s U.S. mediatized literature constitutes a post-modern re-enactment of the traditional oral literature that initially emerged on U.S. territory …

Pacap And Vip Modulation Of Neuroexcitability In Rat Intracardiac Neurons, Wayne I. Dehaven

USF Tampa Graduate Theses and Dissertations

Autonomic control of cardiac function depends on the coordinated activity generated by neurons within the intracardiac ganglia, and intrinsic feedback loops within the ganglia provide precise control of cardiac function. Both pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) are important regulators of cell-to-cell signaling within the intracardiac ganglia, and PACAP and VIP action on these ganglia, mediated through associated receptors, play an important role in the regulation of coronary blood flow, cardiac contraction, relaxation, and heart rate. Results reported here using PACAP and VIP provide direct evidence of some of the complex signaling which occurs in neurons …

Molecular Dynamics And Time Correlation Function Theories, Russell H. Devane

USF Tampa Graduate Theses and Dissertations

The research presented in this thesis makes use of theoretical/computational techniques to calculate nonlinear spectroscopic signals and molecular volumes. These techniques have become more practical with advances in computational resources and now are an integral part of research in these areas. Preliminary results allude to the power of these techniques when applied to relevant problems and suggest that much progress can be made in understanding the complex nature of nonlinear spectroscopic signals and molecular volume contributions. The nonlinear spectroscopy work involves writing the quantum mechanical response functions in terms of classical time correlation functions which are amenable to calculation using …

Anti-Arab Hate Crimes In The Aftermath Of September 11, 2001: Assessing The Influence Of Geographic And Situational Factors, Ilir Disha

USF Tampa Graduate Theses and Dissertations

This study investigates how hate crimes in general and anti-Arab hate crimes in particular were distributed across different regions of the United States during the 2001- 2002 period. The study explores how a historical event – the terrorist attacks against the U.S. on September 11, 2001 – and county population demographics affect the rates of hate crime against Arabs, Muslims or Middle Easterners. It was hypothesized that antiArab or anti-Muslim hate crimes displaced other forms of hate crime and were characterized by open acts of violence. According to the contact hypothesis, anti-Arab and anti-Muslim hate crimes would be more likely …

The Influence Of Stakeholder Groups On The Decision Making Process Regarding The Dead Zone Associated With The Mississippi River Discharge, Lisa M. Fairchild

USF Tampa Graduate Theses and Dissertations

The Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico represents the first national attempt to address this environmental issue. Hypoxia is the condition of low concentrations of dissolved oxygen in a body of water. This condition leads to a so-called “dead zone” and potentially threatens industries dependent on the living marine resources of this area. The potential impact of any policy or plan designed to combat hypoxia in the Northern Gulf of Mexico could have significant impacts on stakeholder groups, specifically the fishing industry in the Gulf of Mexico, and the agriculture and fertilizer …

USF Tampa Graduate Theses and Dissertations

Building upon Granovetter’s well-known study of the job search behaviors of white males, this research extended the degree to which his findings apply across cultures to Chinese minorities, and across time to the Internet age. Using quantitative and qualitative data collected through systematic observation, questionnaire surveys, and in-depth interviews, this research investigated the impact of culture, Internet usage, gender and age on the communication patterns of foreign-born Chinese jobseekers in the U.S.

It is found that jobseekers adopt either one or a combination of traditional (printed publications and direct application), institutional (the Internet, job fairs, and employment agencies), and personal …

“Ethnographizing” Service-Learning: Creating Politically Engaged Anthropology, Wendy Ann Hathaway

USF Tampa Graduate Theses and Dissertations

Service-Learning is a popular teaching method that is increasingly being adopted by institutions of higher learning throughout the nation and is enthusiastically promoted as a progressive method for mediating the alleged decline in civic responsibility and ameliorating subsequent social ills. Servicelearning courses are also seen as an answer to growing student disinterest by connecting students to “real world” experiences while simultaneously providing much needed community support in the face of receding social services in this “Post-Welfare” moment (Goode and Maskovsky 2001a).

Anthropological insights, born out of a liberal humanistic tradition, can be employed to critically examine this popular educational and …

Fat Commentary And Fat Humor Presented In Visual Media: A Content Analysis, Susan Himes

USF Tampa Graduate Theses and Dissertations

In order to examine the phenomenon of fat messages presented through visual media, a content analysis was used to quantify and categorize fat-specific commentary. Fat commentary vignettes were identified using a targeted sampling procedure, and 135 scenes were excised from movies and TV shows. The material was coded by trained raters. Reliability indices were uniformly high for the seven categories (% agreement ranged from .90-.98; kappas ranged from .66-.94). Results indicated that fat commentary and fat humor is often verbal, directed toward another person, and is often presented directly in the presence of the overweight target. Results also indicated that …

Systematic Study Of Amyloid Beta Peptide Conformations: Implications For Alzheimer’S Disease, Jeffy Pilar Jimenez

USF Tampa Graduate Theses and Dissertations

The amyloid beta peptide particularly the 40 and 42 amino acid residues are the responsible for plaque formation in Alzheimer's disease (AD) patients. Extra cellular plaque formation has been recognized after incessant investigations along with the formation of intracellular tau protein tangles as the hallmarks of AD. Furthermore, the plaque formation has been linked mostly as a cause of the disease and the tangles mostly as a consequence. Our investigation is focused on studying the formation of AD plaques. The amyloid beta (Aß) is a physiological peptide secreted from neurons under normal conditions, along with other soluble forms cleaved from …

Simulating The Electric Field Mediated Motion Of Ions And Molecules In Diverse Matrices, Joseph Hickey

USF Tampa Graduate Theses and Dissertations

Electroporation is a methodology for the introduction of drugs and genes into cells. This technique works by reducing the exclusionary nature of the cell membrane [125, 129, 186, 189]. Electroporation has successfully been used in electrochemotherapy and electrogenetherapy [57, 68, 86, 87, 110, 112, 131]. The two major components of electroporation are an induced transmembrane potential and the motion of the deliverable through a compromised cell membrane into the target cell [38, 55, 62, 114, 131]. These two components are both dependent on the electrophoretic motion of charged species in an applied electric field [45, 64, 75, 77, 177].

Currently, …

Performativity And The Latina/O-White Hybrid Identity: Performing The Textual Self, Shane T. Moreman

USF Tampa Graduate Theses and Dissertations

This study is an exploration of Latina/o-White hybrid identity for constructions and negotiations of hybridity as performed in the lives of individuals and as rearticulated in discourse. These discourses are drawn from interviews with nine individuals, stories of my own life, and three published memoirs. Despite these different forms, all the selfidentified Latina/o-White hybrid individuals speak to the difficulty of imagining and enacting a hybrid identity within today’s discourse on race and ethnicity. This study articulates these difficulties as lived experience, theory, and performance come together to argue for and against hybridity as a model for contemporary identity. The project …

The Assessment Of Appearance Factors Related To Intentional Uv Exposure, Guy Cafri

USF Tampa Graduate Theses and Dissertations

Understanding the motives for sunbathing and indoor tanning is an extremely important public health issue. Skin cancer rates have increased dramatically in recent years and UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors. Motives for sunbathing and tanning salon use have been thought to be related to appearance concerns, yet little research has examined the specific tan appearance attitudes that may contribute to use of these behaviors. Two studies were conducted with the aim of assessing distinct attitudes related to a tan appearance. In the first study items were created based …

A Co-Orientational Analysis Of Public Involvement Perceptions In The Transportation Process: A Case Study, Kristen E. Carson

USF Tampa Graduate Theses and Dissertations

This study explored public involvement within the Florida Department of Transportation (FDOT) using the co-orientational theory. Effective public involvement gives the public opportunities to be involved early in the planning and implementation of transportation projects that directly affect or may concern them. The co-orientational model looks at what an organization (FDOT) thinks about an issue (public involvement), what the public thinks of the issue, what the organization thinks the public thinks about the issue, and what the public thinks the organization thinks about the issue.

This study investigated whether the FDOT management has an accurate understanding of the perceptions of …

Social Construction Of Cervical Cancer Screening Among Women In Panama City, Panama, Arlene Calvo

USF Tampa Graduate Theses and Dissertations

To learn how to address health issues specific to Hispanic cultures in an effort to address health disparities, learning from cultural aspects that affect health from the countries of origin would be most useful. Community programs built on rigorous and systematic research prove to be more powerful than ad-hoc programs. Qualitative research techniques offer powerful alternatives for public health professionals to develop adequate and directed programs at the community level, especially among underserved communities and those represented by oral/spoken traditions. The study was conducted among 132 working class single and married Mestizo women between the ages of 20-40 living in …

Effects Of Constructed Response Contingencies In Web-Based Programmed Instruction On Graphing Compared To Cued-Text Presentation Of The Same Information, Reinaldo L. Canton

USF Tampa Graduate Theses and Dissertations

Web-based lessons teaching graph construction techniques (via the internet) were presented to 144 undergraduate and graduate college students. One group experienced program-controlled tutorials requiring them to construct answers in a defined sequence. A second group experienced identical lesson material in the form of typographically cued text presentations. The programmed instruction students performed significantly better than the cued-text group on an immediate computerbased posttest assessing comprehension of the graphing lesson material. The cuedtext group performed better on an applied graphing assignment. The experiment did not account for individual’s internet study habits or the metacognitive approaches to learning employed by the study …

Exploring Women’S Complex Relationship With Political Violence: A Study Of The Weathermen, Radical Feminism And The New Left, Lindsey Blake Churchill

USF Tampa Graduate Theses and Dissertations

In this thesis I use the radical, pro-violent organization the Weathermen as a framework to examine women and feminisms complex relationships with violence. My thesis attempts to show the many belief systems that second wave feminists possessed concerning the role(s) of women and violence in revolutionary organizations. Hence, by using the Weathermen as a framework, I discuss various feminist essentialist and pacifist critiques of violence. I also include an analysis of feminists who, similar to the Weathermen, embraced political violence. For example, radical feminists Robin Morgan and Jane Alpert criticized the Weathermen's violent tactics while other feminists such as Ti-Grace …

Finding My Voice: Adolescent Girls’ Experiences With Speaking Up And How Recounting These Experiences Impacts Future Expression, Deborah A. Cihonski

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine the meaning of the Expression of Voice experience in adolescent girls using an existential-phenomenological interview approach and also to explore the impact of participation in an interview session talking about Voice. Two open-ended interviews were conducted. During the first interview, participants are asked to "Please think of a specific time when you had something important to say, and although it was difficult, you did speak up and say what you thought. In as much detail as possible, describe that experience." During the second interview, each girl was asked if she "... feel[s] …

Dissecting Out The Contribution Of Cognitive, Social, And Physical Activities To Environmental Enrichment’S Ability To Protect Alzheimer’S Mice Against Cognitive Impairment, Jennifer R. Cracchiolo

USF Tampa Graduate Theses and Dissertations

Retrospective studies suggest that lifestyle activities may provide protection against Alzheimer s Disease (AD). However, such studies can be inaccurate and prospective longitudinal studies investigating lifestyle protection against AD are both impractical and impossible to control for. Transgenic (Tg+) AD mice offer a model in a well controlled environment for testing the potential for environmental factors to impact AD development. In an initial study, Tg+ and non-transgenic (Tg-) mice were housed in either environmentally enriched (EE) or standard housing (SH) from 2-6 months of age, with a behavioral battery given during the last 5 weeks of housing. In the Morris …
