In-Vivo Radiation Diode Dosimetry For Therapeutic Photon Beams, Amarjit Singh Saini Jan 2007

In-Vivo Radiation Diode Dosimetry For Therapeutic Photon Beams, Amarjit Singh Saini

USF Tampa Graduate Theses and Dissertations

In-vivo dosimetry with diode detectors is used in radiation therapy as a quality assurance tool. The diode sensitivity under radiation depends upon temperature, dose rate and SDD (source-to-detector distance), field size, beam angle, and energy. This dissertation presents the first systematic and quantitative study of dosimetric characteristics for most of the commercial radiation diodes (n-type and p-type) under different radiation beams.In the temperature dependence study, the systematic study on the dose rate dependence of svwt (sensitivity variation with temperature) was performed. It was concluded that sufficient preirradiation can eliminate dose rate dependence of svwt. However, preirradiation cannot eliminate dose rate …

Generation And Characterization Of An Attenuated Mutant In A Response-Regulator Gene Of Francisella Tularensis Live Vaccine Strain (Lvs), Wendy L. Sammons

USF Tampa Graduate Theses and Dissertations

Francisella tularensis is a zoonotic bacterium that must exist in diverse environments ranging from arthropod vectors to mammalian hosts. To better understand how genes are regulated in these different environments, a transcriptional response- regulator gene (genome locus FTL0552) was deleted in F. tularensis live vaccine strain (LVS). The FTL0552 deletion mutant exhibited slightly reduced rates of extracellular growth but was unable to replicate or survive in mouse macrophages and was avirulent in the mouse model using either BALB/c or C57BL/6 mice. Mice infected with the FTL0552 mutant produced reduced levels of inflammatory cytokines, exhibited reduced histopathology and cleared the bacteria …

The Molluscan And Brachiopod Fauna Of The Late Cretaceous Pierre Shale (Baculites Compressus/Baculites Cuneatus Biozones) Near Kremmling, Colorado, Lanora Ann Sava

USF Tampa Graduate Theses and Dissertations

The Kremmling Paleontological Resource Area (KPRA) contains one of the most fossiliferous units within the Late Cretaceous Western Interior Seaway of North America. It was deposited during the late Campanian Baculites compressus/cuneatus ammonite biozones ((\approx) 72.5 Ma) and records slightly less than one million years of depositional history. Examination of the fauna, its dominant preservational mode and taphonomy as well as the lithologic evidence from measured stratigraphic sections strongly suggests that the depositional environment of the KPRA was a shallow, relatively nearshore environment. A detailed taxonomic examination of the molluscan fauna was undertaken in order to re-evaluate past work as …

Engaging The Eighties: Ethics, Objects, Periods, Kevin L. Ferguson Jan 2007

Engaging The Eighties: Ethics, Objects, Periods, Kevin L. Ferguson

Dissertations, Theses, and Capstone Projects

This dissertation examines a recent decade in American history whose unique notion of self-periodization generated important questions of ethical engagement and withdrawal. Situated during a time of an increasingly complex relationship between literature and theory, thinkers in the 80s self-consciously shifted towards making claims about their present moment which were based on the logic of rupture, and which thus created an either-or logic of pessimism or optimism in response to this rupture. These kinds of self-periodizing notions generally are collected under the rubric "postmodernism" and the first chapter deals with a transatlantic movement between theorists such as Fredric Jameson and …

Testing Impulsivity As A Moderator Of Smoking Motivation Following Exposure To Negative Affect And Smoking Cues, Erika B. Litvin Jan 2007

Testing Impulsivity As A Moderator Of Smoking Motivation Following Exposure To Negative Affect And Smoking Cues, Erika B. Litvin

USF Tampa Graduate Theses and Dissertations

Consistent with classical conditioning theories of drug use, previous research has demonstrated that presenting smokers with either exteroceptive (e.g., pictures of cigarettes) or interoceptive (e.g., negative affect) cues results in increased motivation to smoke, as measured by urge and smoking topography (e.g., shorter latency to begin smoking). However, few studies have presented both types of cues to determine whether and how they might interact in the production of smoking motivation, and little research has focused on identifying potential moderators of cue reactivity. In a randomized 2 x 2 crossed factorial between-subjects design, the current study tested whether an interoceptive cue …

Fabrication: Corporate And Governmental Crime In The Apparel Industry, Danielle Mcgurrin Jan 2007

Fabrication: Corporate And Governmental Crime In The Apparel Industry, Danielle Mcgurrin

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to examine both the gendered and racialized nature of workplace risk and compensation in the manufacturing industry of apparel. The author selects this industry because of its low-wage, labor intensive, and "deskilled" work, performed in often unsafe employment environments with minimal governmental regulations and limited unionization. The apparel industry is also characterized by its large percentage of racial and ethnic minorities, especially immigrant employees, that further disadvantage them in terms of communication barriers, threat of deportation, and the multiple and intersecting marginalizations associated with occupying a low-wage, minority and/or immigrant status. The gendered effects …

Forging Identities Through Style: Elite Interaction And Identity Formation At Late Classic (Ad 650-900) Palmarejo, Northwest Honduras, Claire Novotny Jan 2007

Forging Identities Through Style: Elite Interaction And Identity Formation At Late Classic (Ad 650-900) Palmarejo, Northwest Honduras, Claire Novotny

USF Tampa Graduate Theses and Dissertations

The representation of social affiliation is dependent upon material signifiers that can serve as communicative links between individuals or communities. This study evaluates the material manifestation of an elite social identity during the Late Classic (AD 650-900) period at the site of Palmarejo, northwest Honduras. Previous studies on social identity in prehistory point to the importance of site plans, monumental architecture, ceramics, and human burials in conveying sociocultural messages. A regional comparison of these types of data is made between Palmarejo and three coeval sites in northwest Honduras, La Sierra, El Coyote, and Las Canoas. I argue that the chosen …

A Surviving Legacy: Nonviolent Resistance In The Congresssional Black Caucus 2001-2007, Rhone Sebastian Fraser Jan 2007

A Surviving Legacy: Nonviolent Resistance In The Congresssional Black Caucus 2001-2007, Rhone Sebastian Fraser

USF Tampa Graduate Theses and Dissertations

Select members of the Congressional Black Caucus through their votes, speeches, arrests and nonviolent forms of protest practice a renewed kind of nonviolent resistance against a neoconservative political agenda advanced by the executive branch of the U.S. government in the past six years. Their practices are nonviolent according to the definition of nonviolence discussed by Martin Luther King, Jr. in his 1962 New York Times Magazine article: "we will take direct action against injustice without waiting for other agencies to act...We will try to persuade with our words---but if our words fail we will try to persuade with our acts." …

School Psychologists’ Provision Of School-Based Mental Health Interventions: A Qualitative Study Of Perceived Barriers, Allison A. Friedrich Jan 2007

School Psychologists’ Provision Of School-Based Mental Health Interventions: A Qualitative Study Of Perceived Barriers, Allison A. Friedrich

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to elucidate factors that school psychologists perceive inhibit them from providing more mental health interventions within their professional roles. School psychologists' dual training in mental health and education renders them the logical choice to provide tier II and tier III interventions in schools (National Association of School Psychologists [NASP], 2003). School psychologists appear to be in agreement, as they indicate a desire to spend more time in the provision of roles such as counseling and consultation (e.g., Prout, Alexander, Fletcher, Memis, & Miller, 1993). However, school psychologists currently spend relatively little time in …

Regulation Of Foxo Stability And Activity By Mdm2 E3 Ligase, Wei Fu Jan 2007

Regulation Of Foxo Stability And Activity By Mdm2 E3 Ligase, Wei Fu

USF Tampa Graduate Theses and Dissertations

Members of the forkhead class O (FOXO) transcription factors are tumor suppressors and key molecules that control aging and lifespan. The stability of mammalian FOXO proteins is controlled by proteasome-mediated degradation but general ubiquitin E3 ligases for FOXO factors remain to be defined. The current studies demonstrate that MDM2 bound to FOXO1 and FOXO3A and promoted their ubiquitination and subsequent degradation, a process apparently dependent on FOXO phopshorylation at PKB sites and on the E3 ligase activity of MDM2. The binding occurred between endogenous proteins and was involved the forkhead box of FOXO1 and the region of MDM2 that controls …

Analysis Of E2f1 Target Genes Involved In Cell Cycle And Apoptosis, Scott N. Freeman Jan 2007

Analysis Of E2f1 Target Genes Involved In Cell Cycle And Apoptosis, Scott N. Freeman

USF Tampa Graduate Theses and Dissertations

One of the main results of Rb-E2F pathway disruption is deregulation of the E2F family of transcription factors, which can lead to inappropriate proliferation, oncogenic transformation, or the induction of apoptosis. Given the potential negative biological effects associated with deregulated E2F activity, it is of great importance to study E2F targets that mediate these effects. In Part I of this manuscript, we identify the RhoBTB2 putative tumor suppressor gene as a direct physiological target of the E2F1 transcription factor. We find that RhoBTB2 is highly upregulated during mitosis due in part to E2F1, and that overexpression of RhoBTB2 increases the …

Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz Jan 2007

Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz

USF Tampa Graduate Theses and Dissertations

Theodor W. Adorno, the towering twentieth century German intellectual figure and distinctive musical thinker, was legendary for being over-critical of jazz music. Through a consideration at his admiration for avant-garde chamber and symphonic music, I plan to develop a position that, surprisingly, points towards a theory of unacknowledged acceptance of jazz. The style of jazz that will be the newly constructed musical idiom of admiration for Adorno will be of the heterodox variety. My method of reconstruction will be to interrogate the inconsistencies in Adorno's critical musical writings, and negate such negations with factual evidence of affirmation found in the …

Relationship Between Biofilm Removal And Membrane Performance Using Dunedin Reverse Osmosis Water Treatment Plant As A Case Study, Joshua E. Goldman Jan 2007

Relationship Between Biofilm Removal And Membrane Performance Using Dunedin Reverse Osmosis Water Treatment Plant As A Case Study, Joshua E. Goldman

USF Tampa Graduate Theses and Dissertations

Membrane biofouling is a common occurrence in water treatment plants that utilize reverse osmosis (RO). As bacteria and biofilm material build up on the membrane surface, it becomes more difficult for clean water to permeate through the membrane, and more pressure is required to produce the same amount of water. When pressures become critically high, membranes must be cleaned. This process is expensive in terms of chemical cost, labor, and downtime. Even after membranes have been cleaned, they can re-foul quickly if the cleaning did not effectively remove the biofilm. The water treatment plant in Dunedin, FL, which uses RO …

Changing The Subject: First-Person Narration In And Out Of The Classroom, Susan Friedman Jan 2007

Changing The Subject: First-Person Narration In And Out Of The Classroom, Susan Friedman

USF Tampa Graduate Theses and Dissertations

The effectiveness of first-person narration for self-transformation and social change is indicated by exploring connections between three emergent discourses: illness narratives and memoirs by rape survivors in which the subject speaks from a privileged yet socially marginalized position about life-altering experiences; clinical discourse that elaborates treatment methods for empowering trauma survivors and helping them reconnect with the social world; and scholarly discourse that reflects on the relationship between trauma, self-representation, witnessing, and recovery. Post-Foucauldian theories of life-writing illuminate how the author-subjects of survivor narratives discursively reconstruct their shattered subjectivity in a therapeutic relationship with themselves and their readers. Cognitive and …

Transfer Track Versus Workforce Development: Implications For Policy Change In Florida Community Colleges, Karen Griffin Jan 2007

Transfer Track Versus Workforce Development: Implications For Policy Change In Florida Community Colleges, Karen Griffin

USF Tampa Graduate Theses and Dissertations

Policy-makers intend community colleges to be the primary vehicles for workforce development education and training. In support of this intent, community college mission statements and curricular patterns should clearly indicate a workforce emphasis. Do these statements and curricular patterns reflect policy intent? If not, are resources being directed appropriately? This study was conducted to determine whether the current composition of the overall Florida public community college curriculum and the content of Florida public community college mission and planning statements provided evidence to support Florida leadership policy statements that portray workforce development as a primary component of the community college mission. …

Do You See What I Mean? Measuring Consensus Of Agreement And Understanding Of A National Weather Service Informational Graphic, Lorna M. Geggis

USF Tampa Graduate Theses and Dissertations

Media use of hurricane graphics to apprise populations vulnerable to severe weather provides a persuasive demonstration of the importance and complexity of visual communication. Surprisingly little research, however, has explored how audiences interpret weather graphics. This study examined whether the general public and the National Weather Service share a common understanding of selected weather related terms and meaning of a NWS informational graphic. Using a coorientation model, general public responses to a questionnaire were compared to definitions prescribed by the NWS. Additionally, the public were asked questions to measure trust of the NWS as a credible and reliable source of …

Forbidding And Enforcing Of Formal Languages, Graphs, And Partially Ordered Sets, Daniela Genova Jan 2007

Forbidding And Enforcing Of Formal Languages, Graphs, And Partially Ordered Sets, Daniela Genova

USF Tampa Graduate Theses and Dissertations

Forbidding and enforcing systems (fe-systems) provide a new way of defining classes of structures based on boundary conditions. Forbidding and enforcing systems on formal languages were inspired by molecular reactions and DNA computing. Initially, they were used to define new classes of languages (fe-families) based on forbidden subwords and enforced words. This paper considers a metric on languages and proves that the metric space obtained is homeomorphic to the Cantor space. This work studies Chomsky classes of families as subspaces and shows they are neither closed nor open. The paper investigates the fe-families as subspaces and proves the necessary and …

The Appeal Of The Underdog: Definition Of The Construct And Implications For The Self, Nadav Goldschmied Jan 2007

The Appeal Of The Underdog: Definition Of The Construct And Implications For The Self, Nadav Goldschmied

USF Tampa Graduate Theses and Dissertations

From politics to sports to business, people are quick to categorize those at a considerable competitive disadvantage as "underdogs." Moreover, there is ample support that most unattached observers do not hesitate to align themselves with underdogs, a phenomenon termed "the underdog effect." While most dictionary definitions state that underdogs are "especially expected to lose," the present investigation argues that people often attribute optimistic qualities to underdogs and the exceeding of expectations. A series of studies was conducted to examine the lay-person definition of what an underdog means, as well as what motivations may play a role in the underdog effect. …

Johnson’S System Of Distributions And Microarray Data Analysis, Florence George

USF Tampa Graduate Theses and Dissertations

Microarray technology permit us to study the expression levels of thousands of genes simultaneously. The technique has a wide range of applications including identification of genes that change their expression in cells due to disease or drug stimuli. The dissertation is addressing statistical methods for the selection of differentially expressed genes in two experimental conditions. We propose two different methods for the selection of differentially expressed genes. The first method is a classical approach, where we consider a common distribution for the summary measure of equally expressed genes. To estimate this common distribution, the Johnson system of distribution is used. …
