Florida: Presidential Elections And Partisan Change, 1952-2004, Matthew Thomas Jefferys

USF Tampa Graduate Theses and Dissertations

The presidential contest of 1952 established a new trajectory for Florida politics. This pivotal election reversed decades of Democratic dominance and signified the beginning of presidential Republicanism in the state. Elections in the second half of the 20th century provided evidence of an increasingly favorable environment for Republican nominees. During this period Democrats were limited to carrying the state’s electoral votes three times. GOP presidential ascendancy in Florida was augmented by partisan conversion and the disproportionate in-migration of white Northerners following World War II. Contrary to unrivaled 1980s support, which created an anchor in a new core Southern Republican electoral …

Influence Of Gender On Heart Rate And Core Temperature At Critical Wbgt For Five Clothing Ensembles At Three Levels Of Metabolic Rate, Maeen Zakaria Islam

USF Tampa Graduate Theses and Dissertations

Three main factors that influence heat stress are clothing, work demands and environmental conditions. Gender may also influence the amount of heat stress an individual can tolerate. The purpose of this study was to examine the role of gender in heat stress limits (critical WBGT) and heat strain (heart rate and core temperature). The null hypothesis was that there was no gender difference among critical WBGT, heart rate and core temperature.

Fifteen subjects (11 men and 4 women) wore five different clothing ensembles (cotton work clothes, cotton coveralls, particle barrier Tyvek, water-barrier/vapor permeable NexGen LS417, and vapor barrier Tychem QC …

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 …

The Effects Of Small-Scale Heterogeneities On Aquifer Storage Recovery Systems, William C. Hutchings

USF Tampa Graduate Theses and Dissertations

Aquifer Storage Recovery (ASR) is a recently developed (circa 1970) method (in the U.S.A.) to reduce groundwater-pumping stresses by injecting treated wastewater or surface water during periods of low demand into an aquifer followed by its recovery during periods of high demand. This method has been successfully implemented in numerous locations across the U.S.A. and worldwide, mainly due to the cost savings provided by the use of an unlimited reservoir (aquifer) in which to store water compared to the costs to construct surface impoundments and the inherent problems with storing such water for extended periods of time under evaporative atmospheric …

Temporal Comparisons And The Perception Of Posttraumatic Growth In Early Stage Cancer Patients, Sean Ransom

USF Tampa Graduate Theses and Dissertations

Like others who endure serious stressors, cancer patients often report personal growth as a result of their illness, a phenomenon termed "posttraumatic growth." Although researchers often accept these reports as valid, temporal comparison theory suggests that people may overestimate such growth. According to the theory, remembering the past self as less positive than the present self may serve as an illusory self-enhancement process that allows one to see continual personal growth. Thus, reports of posttraumatic growth may represent perceived rather than actual change in the self. To test this possibility, we prospectively examined 88 individuals with early stage breast (Stage …

Connected Domination In Graphs, Gayathri Mahalingam

USF Tampa Graduate Theses and Dissertations

A connected dominating set D is a set of vertices of a graph G = (V, E) such that every vertex in V − D is adjacent to at least one vertex in D and the subgraph hDi induced by the set D is connected. The connected domination number γc(G) is the minimum of the cardinalities of the connected dominating sets of G. The problem of finding a minimum connected dominating set D is known to be NP-hard. Many polynomial time algorithms that achieve some approximation factors have been provided earlier in finding a minimum connected dominating set. In …

The Role Of Sensation Seeking In Children’S Ability To Learn Alcohol Expectancy Associations, Nicole M. Bekman

USF Tampa Graduate Theses and Dissertations

Sensation seeking is a personality characteristic associated with problematic alcohol use and positive alcohol expectancies, but little research has examined the relationship between sensation seeking and the acquisition of alcohol expectancy information. In a recent study (Steinberg, 2003), sensation seeking was associated with how quickly and accurately college-aged students were able to learn alcohol-expectancy word pairs in a paired associate learning task. In this age group, however, the individuals had fully developed alcohol expectancies that may have influenced their rates of learning.

The current study sought to minimize the influence of previously held alcohol expectancies by exploring this relationship in …

Sorption Of Organic Vapors By Copolymers Of Poly (Styrene-Butadiene) Using A Piezoelectric Microbalance, Anant K. Upadhyayula

USF Tampa Graduate Theses and Dissertations

Thickness shear mode (TSM) sensors, also known as quartz crystal microbalances (QCM) are a class of acoustic wave sensors that have been used for gas phase sensing. In this thesis this device is used to measure vapor-liquid equilibrium data for copolymers of poly(styrene-butadiene) at 294K.

Copolymers of poly(styrene-butadiene) with varying percentages of styrene (85%, 45% and 21 %) were studied with benzene, n-hexane, dichloroethane and chloroform as solvents. Literature data for pure polystyrene/benzene and polystyrene/chloroform and polybutadiene/benzene were obtained to complement the measured data.

Obtained experimental data were fit with a modified Flory-Huggins model and compared with the predictions of …

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 Benefits Of Clear Speech At Normal Rates For Older Listeners With Normal Hearing, Athina Panagos Panagiotopoulos

USF Tampa Graduate Theses and Dissertations

Clear speech is a type of speaking style that improves speech intelligibility for many individuals. For example, one study showed a 17 percentage point increase in intelligibility over conversational speech for individuals with sensorineural hearing loss (Picheny et al., 1985). The clear speech benefit also extends to children with learning disabilities (Bradlow et al., 2003), non-native listeners (Bradlow & Bent, 2002), and other populations. Although clear speech is typically slower than conversational speech, it can be produced, naturally, at normal rates with training. For young listeners with normal hearing, clear speech at normal rates (clear/normal) is more intelligible than conversational …

A Future With Hope: The Social Construction Of Hope, Help, And Dialogic Reconciliation In A Community Children's Mental Health System Of Care, Christine S. Davis

USF Tampa Graduate Theses and Dissertations

This research examines the social construction of hope in a community mental health system of care. Groopman (2004) defines hope as the elevating feeling we experience when we see a path to a better future. A year-long ethnographic study of a children's mental health system of care team found that members of the mental health care team construct hope for themselves and for the family they're helping by cycling through the dialectical tensions of hegemony and equality, marginalization and normalization, relating and othering, empowerment and disempowerment, and control and emotionality. They reconcile these tensions in dialogic moments of empathy toward …

The Cost Of Professionalization: A Case Study Of Osteopathic Medicine In The United States, Rochelle Harris

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate the co-optation of the heterodox medical system of osteopathic medicine by the hegemonic medical system of biomedicine and its impact on the practice of osteopathic medicine in America. The study particularly explored students (n=20), practitioners (n=5), and faculty (n=5) regarding their views of osteopathic medicine. The process of professionalization of osteopathic medicine has caused DOs to become more akin to MDs, which may have led to an identity crisis within the profession. This case study took place at a private osteopathic medical school in the Southeastern U.S. A content analysis of the …

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].

Cross-Formational Flow, Diffluence And Transfluence Observed In St. Beatus Cave And Sieben Hengste (Switzerland), Philipp Häuselmann

International Journal of Speleology

Observations in St. Beatus Cave and neighbouring caves revealed complex water flowpaths that can be used for explaining the behaviour of tracing experiments. The observations prove that even in vadose conditions, cross-formational flow, diffluences and transfluences are a quite common feature. Therefore, also the vadose karst has a very complex organisation.

Partitions, Compartments And Portals: Cave Development In Internally Impounded Karst Masses, R. Armstrong L. Osborne

International Journal of Speleology

Dykes and other vertical bodies can act as aquicludes within bodies of karst rock. These partitions separate isolated bodies of soluble rock called compartments. Speleogenetically each compartment will behave as a small impounded-karst until the partition becomes breached. Breaches through partitions, portals, allow water, air and biota including humans to pass between sections of caves that were originally isolated.

Radon In Caves, Arrigo A. Cigna

International Journal of Speleology

The physical characteristics of radon are reported as well as its sources,the transport in rock and its behaviour in caves. Then, the instruments,both active and passive, used for the measurement of radon concentration are discussed by taking into account their respective advantages and disadvantages for the use in the cave environment. Since in many countries radon is the object of regulations that were adopted for radiation protection purposes, this aspect is examined and the recommendations issued by international organisations and enforced in different countries are reported. Materials, methods and other remarks on the limits implementation are also listed with the …

Cavity-Based Secondary Mineralization In Volcanic Tuffs Of Yucca Mountain, Nevada: A New Type Of The Polymineral Vadose Speleothem, Or A Hydrothermal Deposit?, Yuri V. Dublyansky, Sergey Z. Smirnov

International Journal of Speleology

Secondary minerals (calcite, chalcedony, quartz, opal, fl uorite, heulandite, strontianite) residing in open cavities in the Miocene rhyolite tuffs of Yucca Mountain, Nevada have been interpreted by some researchers as "speleothemic" formations, deposited as a result of downward infi ltration of meteoric waters (DOE, 2001, Whelan et al., 2002). The major mineral of the paragenesis, calcite, shows spectacular trend of the textural and crystal morphology change: from anhedral granular occurrences, through (optional) platelet, bladed and scepter varieties, to euhedral blocky morphologies. The trend is consistent with the overall decrease in the supesaturation of the mineral forming solution. Stable isotope properties …

Conceptualisation Of Speleogenesis In Multi-Storey Artesian Systems: A Model Of Transverse Speleogenesis, Alexander Klimchouk

International Journal of Speleology

Conceptual and respective quantitative models of speleogenesis/karstification developed for unconfined aquifers do not adequately represent speleogenesis in confined settings. A conceptual model for speleogenesis in confined settings is suggested, based on views about hydraulic continuity in artesian basins and close cross-formation communication between aquifers in multi-storey artesian systems. Soluble units sandwiched between insoluble porous/fissured formations (common aquifers) initially serve as low permeability beds separating aquifers in a confined system. Conduits evolve as result of vertical hydraulic communication between aquifers across the soluble bed ("transverse speleogenesis"). Recharge from the adjacent aquifer is dispersed and uniform, and flow paths across the soluble …

Do Expectancies Influence Outcomes For Tailored Smoking Cessation Messages? A Placebo Tailoring Experiment, Monica S. Webb

USF Tampa Graduate Theses and Dissertations

This study was an effort to replicate and extend findings from our previous research, which suggested that the efficacy of tailored messages is influenced by high levels of content personalization within the message and by individuals trait expectancies about tailored interventions. We tested whether tailoring-related expectancies regarding smoking-cessation booklets could be altered via a brief expectancy-priming intervention, and whether this would enhance the impact of the cessation materials. A 2x2 factorial design crossed personalization level and expectancy priming on evaluation of the intervention content, readiness to quit smoking, cessation self-efficacy, cognitive processing, and progress towards quitting. Smokers (N = 205) …

A Survey Of Electronic Purchasing Practice In Ireland: A Perspective For The Irish Construction Industry, Alan V. Hore, Roger West

Conference papers

There are many millions of trading documents (such as purchase orders, delivery notes and invoices) currently exchanged on paper in business to business (B2B) transactions, each having to be re-keyed as they pass between different locations and computer applications. Existing Information Communications Technologies (ICTs) such as the Internet, Bar-Coding, Radio Frequency Tagging, Electronic Data Interchange (EDI), Electronic catalogs and Enterprise Resource Planning Software (ERP) have facilitated electronic commerce (EC) functionality within many business sectors. However, the adoption of such technologies in the Irish construction industry has been very slow with only limited evidence of their application. The results of a …

Realising Electronic Purchasing In The Irish Construction Industry, Alan V. Hore, Roger West

Conference papers

The use of Information Communication Technologies (ICT) in construction purchasing has been sporadic and piecemeal. Very significant inefficiencies and problems still exist in both paper transactions and non-integrated electronic solutions. At the simplest level, the electronic transmission of business documents offers savings in paper and postage. By going a step further, businesses can make strides in communicating with their partners, at relatively low cost, through direct links between their computers. Existing ICT such as the Internet, Bar-Coding, Radio Frequency Tagging, Electronic Data Interchange (EDI), Electronic catalogs and Enterprise Resource Planning Software (ERP) have facilitated electronic commerce (EC) functionality within many …
