Puerperal Fever In Britain: Failed Models Of Disease Causation, Jessica Wells

USF Tampa Graduate Theses and Dissertations

In eighteenth- and nineteenth-century Britain, a bacterial infection which we now

know to be caused primarily by a streptococcus, was killing women in childbirth at an

alarming rate. The disease, called puerperal, or childbed, fever, was being transmitted

primarily from doctor to patient by a doctor’s unwashed hands and filthy, contaminated

clothing and linens. Despite this evident and, in retrospect, obvious vector, the doctors of

this period never discovered how to prevent their patients from dying a gruesome and

painful death. Many physicians wrote extensive accounts of the illness but often ended

their works in despair, unable to find the …

Evaluation Of Oncology Nurses' Knowledge, Practice Behaviors, And Confidence Specific To Chemotherapy Induced Peripheral Neuropathy, Rebecca Denise Mcallister

USF Tampa Graduate Theses and Dissertations

Chemotherapy induced peripheral neuropathy (CIPN) remains one of the most serious and challenging symptoms oncology nurses encounter in caring for patients receiving neurotoxic chemotherapy. CIPN is under-addressed, under-reported, and symptoms are minimized by healthcare providers, which adversely affect patient quality of life, physical function, and emotional well-being. There is an absence of research examining nurses’ knowledge and practice behaviors related to CIPN. The purpose of this study was to explore oncology nurses knowledge, practice behaviors, confidence, and the relationship between education, experience, and knowledge specific to CIPN.

Data was collected at Oncology Nursing Society (ONS) Chapter meetings throughout central and …

Rehabilitation Of Precast Deck Panel Bridges, Atiq H. Alvi

USF Tampa Graduate Theses and Dissertations

USF completed a research study in 2005, which prioritized the replacement of 85 deteriorating composite precast deck panel bridges. This thesis re-evaluates the original recommendations in the wake of failures of two of these bridges in 2007. Since funding will not allow all identified bridges to be replaced, it was necessary to determine the most effective repair methods. To assess USF’s recommendations, a forensic study was undertaken in which the most current inspection and work program documents on the two failed bridges were reviewed and FDOT personnel interviewed. The best repair procedures were determined by reviewing repair plans, specifications, reports …

Visualizando La Conciencia Mestiza: The Relation Of Gloria Anzaldúa’S Mestiza Consciousness To Mexican American Performance And Poster Art, Maria Cristina Serrano

USF Tampa Graduate Theses and Dissertations

This thesis explores Gloria Anzaldúa’s notion of

mestiza consciousness and its

relation to Mexican American performance and poster art. It examines how the traditional

conceptions of

mestizo identity were redefined by Anzaldúa’s Borderlands/La Frontera

in an attempt to eradicate oppression through a change of consciousness. Anzaldua’s

conceptions are then applied to Guillermo Gomez-Peña’s performance art discussing the

intricacies and complexities of his performances as examples of

mestiza consciousness.

This thesis finally analyzes various Mexican American posters in relation to both

Anzaldúa and Gomez-Peña’s art works. It demonstrates that the similarities in the artist’s

treatment of hybridity illustrate a progressive change …

Characterization Of The Role Of Nicotine And Delta 9-Thc In Modulation Of Neuroinflammation, Jared C. Ehrhart

USF Tampa Graduate Theses and Dissertations

Neuroinflammation is a major driving force in the progression of neurodegenerative disorders. Nicotinic acetylcholine receptors, as well as cannabinoid CB2 receptors, have been shown to have strong anti-inflammatory properties when activated. These effects are shown, in vivo, to be a result of stimulation of α7 nAChRs and CB2 cannabinoid receptors. Microglia cells, an immune cell in the brain, are shown to express both of these receptor subtypes. The studies detailed herein, investigated the ability of two compounds, nicotine and Δ9-THC, in modulation of inflammatory processes. Stimulation of these receptors on microglia using nicotine and Δ9-THC blocked the activation of these …

Capillary Self-Assembly And Its Application To Thermoelectric Coolers, James K. Tuckerman

USF Tampa Graduate Theses and Dissertations

The thermoelectric effect was discovered well over a century ago, yet performance has not shown improvement until recent years. Prior work has shown that the thermoelectric effect can be enhanced by the use of microscale pieces of thermoelectric material. Conventional assembly techniques are inadequate to deal with parts of this size, making it necessary to find a suitable alternative before these devices can be made economically. Capillary self-assembly is a promising alternative to conventional techniques. This method employs the use of preparing substrates with areas of favorable surface tension to place and align parts. Still, many obstacles have to be …

USF Tampa Graduate Theses and Dissertations

Geologic sequestration of carbon dioxide (CO

2) in a deep, saline aquifer is being proposed for a power-generating facility in Florida as a method to mitigate contribution to global climate change from greenhouse gas (GHG) emissions. The proposed repository is a brine-saturated, dolomitic-limestone aquifer with anhydrite inclusions contained within the Cedar Keys/Lawson formations of Central Florida. Thermodynamic modeling is used to investigate the geochemical equilibrium reactions for the minerals calcite, dolomite, and gypsum with 28 aqueous species for the purpose of determining the sensitivity of mineral precipitation and dissolution to the temperature and pressure of the aquifer and the salinity …

Design And Fabrication Of A Membrane Integrated Microfluidic Cell Culture Device Suitable For High-Resolution Imaging, Alla A. Epshteyn

USF Tampa Graduate Theses and Dissertations

Malaria remains a serious concern for people living and traveling to warm climates in Africa, Asia, and some parts of America. Understanding the mechanism of the malaria parasite in the liver phase could lead to important discoveries for preventative and treatment therapeutics before the disease develops into the blood stage. While in vitro liver cell culture models have been explored, a device that mimics the liver cell architecture with the capability of high-resolution imaging has never been created. In this research, a cell culture microfluidic device was designed and fabricated with a membrane integrated design to mimic the architecture of …

The Effects Of Directional Audit Guidance And Estimation Uncertainty On Auditor Confirmation Bias And Professional Skepticism When Evaluating Fair Value Estimates, Norma R. Montague

USF Tampa Graduate Theses and Dissertations

In this study, I examine the effects of audit guidance and estimation uncertainty on auditors’ confirmation bias and professional skepticism when evaluating fair value estimates. Fair value estimation is becoming more prevalent in financial reporting frameworks, and regulators warn that fair value estimation presents higher risk of material misstatement when greater judgment in estimation is involved. In addition recent evidence from the Public Company Accounting Oversight Board (PCAOB) indicates that some auditors may not be exercising sufficient professional skepticism when performing audit procedures in higher risk areas of the audit. Martin et al. (2006) suggest that it may be the …

From Night To Dawn: The Cultural Criticism Of George A. Romero, Christopher Paul Wagenheim

USF Tampa Graduate Theses and Dissertations

Analyzing George A. Romero's Night of the Living Dead (1968) and Dawn of the Dead (1978) in relation to the early works of Marshal McLuhan, Erich Fromm, and Herbert Marcuse reveals an ideological parallel that can be explicated using Antonio Gramsci's theory of cultural hegemony. While McLuhan, Marcuse, and Fromm observe, in order to critique, social manifestations of power in a consumerist system, Romero presents a model of hegemony in his films that he exposes to extreme stress thereby allowing viewers to observe such manifestations of power for themselves. These analyses are significant because although Marcuse, McLuhan, Fromm, and Romero …

This study evaluates the disparities in the use of diagnostic cardiac catheterization and PCI in STEMI patients with dementia. A retrospective analysis was performed of Florida‟s comprehensive inpatient surveillance system for the years 2006-2007 with admission diagnosis of STEMI. Logistic regression analysis was used to identify disparities in the use of intervention among all STEMI patients. A total of 8,331 STEMI patients met the inclusion criteria. Of these, 77% were catheterized and of these 67% received PCI. A total …

A Novel Approach To X-Ray Mirror Bending Stability And Control, Michael Weinbaum

USF Tampa Graduate Theses and Dissertations

A novel, no-contact approach to X-ray mirror bending control is presented here,

proposed for use on the beamlines of the European X-ray Free Electron Laser (XFEL)

project. A set of mirrors with tunable bending radii are desired, that will maintain their

optical properties even as the beam incidence causes local heating. Various mechanical

bending mechanisms have been proposed and used on other beamlines, which can take up

a lot of physical space, demanding more vacuum power, while using expensive high

precision servomotors. Rather than bend the mirror by mechanical means, it is proposed

to heat the mirror to produce the …

Dynamics Of Teacher Self-Efficacy: Middle School Reading And Language Arts Teacher Responses On A Teacher Sense Of Efficacy Scale, Kimberly Ann Schwartz

USF Tampa Graduate Theses and Dissertations

Efficacy is created early in a career and not easily influenced over time yet states and school districts loose tremendous amounts of money annually educating and training teachers who elect to leave the profession as a result of low self-efficacy. The purpose of this study was to examine the perceived levels of self-efficacy of middle school Language Arts and reading teachers at various stages in their teaching careers in an attempt to inform the practices of teacher preparation. The Teacher Sense of Efficacy Scale along with a Teacher Demographic Survey was used to identify how preparation method, content area, and …

The Design And Synthesis Of Functionalized Porphyrins And Their Applications In Group Transfer Reactions, Medicine, And Materials, Kimberly Bliss Fields

USF Tampa Graduate Theses and Dissertations

Porphyrins and their analogs are a class of chemically and biologically important compounds that have found a variety of applications in different fields such as catalysis, medicine, and materials. The physical, chemical, and biological dependence of the peripheral substituents of porphyrins on their properties has prompted great effort towards the synthesis of new porphyrins with different electronic, steric, and conformational environments. To this end, porphyrins have been prepared using a modular approach from bromo- and triflate synthons. These synthons underwent palladium-catalyzed cross-coupling with chiral amines, amides, alcohols, and boronic esters to create products that were tested for biological activity.

Metalloporphyrins …

This study involved families of young children with autism spectrum disorders to

examine the feasibility of implementing an adapted version of the school-based Prevent-Teach-

Reinforce (PTR) model. This research included two families who developed and implemented the

intervention for their children in collaboration with the researcher. The PTR manual was modified

for use in a family context. The PTR intervention was tested using a multiple baseline design

across routines. Procedural fidelity was assessed during training and coaching, as well as family

implementation fidelity and social validity. To examine the potential efficacy of the adapted PTR

intervention, the children’s target problem …

Analysis Of Stochastic Disruptions To Support Design Of Capacitated Engineered Networks, Andrés Fernando Uribe-Sánchez

USF Tampa Graduate Theses and Dissertations

This work is a compilation of four manuscripts, three of which are published and one is

in the second round of review, all in refereed journals. All four manuscripts focus on analysis

of stochastic disruptions to support design of capacitated engineered networks. The work

is motivated by limited ability to mitigate elevated risk exposure of large-scale capacitated

enterprise networks functioning in lean environments. Such inability to sustain enterprise

capacity in the face of disruptions of various origins has been causing multi-billion enterprise

forfeitures and hefty insurance premiums. At the same time, decision support methodologies

for reliable design of dynamic capacitated …

Phenotypic And Genotypic Analysis Of In Vitro Selected Artemisinin Resistant Plasmodium Falciparum, Matthew Scott Tucker

USF Tampa Graduate Theses and Dissertations

Artemisinin and its derivatives provide faster clearance of parasitemia than any other antimalarial drugs and these drugs are part of frontline combination therapies in areas where drug-resistant Plasmodium falciparum exists. Clinical resistance to artemisinins is emerging on the Thailand-Cambodia border, making it imperative to investigate mechanisms of artemisinin resistance. Previous work in our laboratory showed ring-stage parasites enter a dormant state after exposure to artemisinin. We hypothesize that this period of dormancy is directly related to recrudescence and prolonged parasite clearance times in patients, and possibly resistance. The target of artemisinin is currently unknown, and potential resistance mechanisms are not …

Gender And Cocaine Use Influence The Expression Of Urinary Markers Of Inflammation And Oxidative Stress, Marie Meagher Bourgeois

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate whether or not gender differences may be present in the expression of a number of urinary proteins which may serve as markers of inflammation and oxidative stress. Males and females have different patterns of illness and different life spans, suggesting basic biological traits exert significant control on the incidence of rhabdomyolysis, renal failure, atherosclerosis, myocardial ischemia, myocardial contraction band formation, autoimmune disorders and general inflammatory diseases. Men are at greater risk for cardiovascular disease; however women, particularly elderly women, have higher fatality rates due to heart failure. Renal diseases progress far more …

News Media Representations Of Women In The U.S. Military Post September 11, 2001, Colleen Krepstekies

USF Tampa Graduate Theses and Dissertations

This paper examines newspaper portrayals produced by the

Washington Post, the New York Times, and the Los Angeles Times of women in the military from Sept. 11, 2001, to Sept. 11, 2009. The purpose was to identify how the three nationally recognized U.S. newspapers depict women’s expanding combat roles on contemporary battlefields that lack definitive front lines. Because the news media are the primary vehicle to update the general public on military matters, how the news media portray military women can play a role in shaping audience perceptions of military women. In turn, this relationship can influence the …

A Contingent Valuation Of Tampa’S Urban Forest Resource, Alec Foster

USF Tampa Graduate Theses and Dissertations

Urban forests provide environmental, social, and economic benefits to urban residents. These benefits are often overlooked when making spatial and financial distributive decisions in urban areas. The City of Tampa has demonstrated interest in its urban forest resource and estimated its extent and some of the benefits provided. Estimating economic values for benefits that have not been quantified can help to ensure that resources are distributed more efficiently. Five methods to estimate urban forest benefits in the City of Tampa are reviewed, with contingent valuation being the method chosen out of this review process. A mailed, dichotomous choice contingent valuation …

An Evaluation Of The Prevent-Teach-Reinforce (Ptr) Model In A Community Preschool Setting, Laura L. Kulikowski

USF Tampa Graduate Theses and Dissertations

This study evaluated the use of the Prevent-Teach-Reinforce (PTR) model with two four-year-old children in a community preschool classroom. A multiple baseline design across activities was used to assess the teacher implementation of the behavior intervention strategies developed during the PTR team process and the changes in child problem behavior and engagement. Additional measures associated with the outcomes, such as researcher procedural integrity and social validity were assessed. The results suggest that the team of teachers were able to implement the PTR intervention with fidelity, which resulted in a decrease in the children’s problem behavior and an increase in their …

The Relationship Between Knowledge And Beliefs About Human Papillomavirus, Acceptance Of The Human Papillomavirus Vaccine, And Intentions To Practice Safer Sex Behaviors Among Female College Students, Theresa Scorcia-Wilson

USF Tampa Graduate Theses and Dissertations

Introduction. Sexually transmitted infections (STIs) continue to be highly prevalent among young women, and STIs continue to be a challenging health issue on college campuses. Studies have shown that the highest prevalence of human papillomavirus (HPV) is among young adult women, ages 20 to 24, including female college students. While the HPV vaccine has proven to be highly effective in preventing certain high-risk types of HPV, it is not effective in preventing all types of HPV or other STIs. Practicing other safer sex behaviors, in addition to condom use, also can help individuals protect themselves and their partners from …

Predictors Of Peer Referral Intentions For Individuals At Risk For Suicide Related Behavior: An Application Of The Theory Of Planned Behavior, Sarah J. Tarquini

USF Tampa Graduate Theses and Dissertations

The role of peer gatekeepers is crucial in connecting individuals at risk for suicide

related behaviors to mental health service providers. However, limited research has

focused on the role of peers as potential helpers for those at-risk. The current study

utilized a mixed experimental and correlational design to examine predictors of female

college students’ referral intentions following hypothetical interactions with peers at-risk

for suicide related behavior. More specifically, the current project examined the utility of

an extended Theory of Planned Behavior (TPB) model of peer-referral intentions. In

addition to the original TPB constructs of attitudes, subjective norms, and perceived

behavioral …

Molecular Mechanism Of Agc Kinases In Human Malignant, Shaokun Shu

USF Tampa Graduate Theses and Dissertations

The maintenance of normal cell function and tissue homeostasis is dependent on the precise regulation of multiple signaling pathways that control cellular decisions to either proliferate, differentiate, arrest cell growth, or initiate programmed cell death (apoptosis). Cancer arises when clones of mutated cells escape this balance and proliferate inappropriately without compensatory apoptosis. Deregulated cell growth occurs as a result of perturbed signal transduction that modulates or alters cellular behavior or function to keep the critical balance between the rate of cell-cycle progression (cell division) and cell growth (cell mass) on one hand, and programmed cell death (apoptosis, autophagy) on the …

Kinematic And Experimental Evaluation Of Commercial Wheelchair-Mounted Robotic Arms, John William Capille Jr.

USF Tampa Graduate Theses and Dissertations

Commercially available wheelchair-mounted robotic arms (WMRAs) are becoming more prevalent internationally but have yet to be largely developed and approved by the Food and Drug Administration in the United States. The purpose of this study was to experimentally evaluate commercially available WMRAs in a controlled test environment. The goal was to quantitatively compare each device through a standardized testing protocol. The study produced theoretical manipulability measurements as well as efficacy ratings of each device based on Denavit-Hartenberg kinematic parameters and physical testing, respectively. Both the manipulator and control devices of WMRA systems were evaluated. The iARM WMRA system was presented …

Contemporary Afro-Cuban Voices In Tampa: Reclaiming Heritage In “America’S Next Greatest City”, Linda M. Callejas

USF Tampa Graduate Theses and Dissertations

This dissertation presents findings from ethnographic research conducted with members of the Sociedad La Unión Martí-Maceo, established by segregated Black Cuban cigar workers in Ybor City in 1904. For decades, Tampa officials have initiated numerous urban revitalization projects aimed at developing a world-class tourist destination and metropolitan center. Often, these efforts have centered on highlighting the ethnic history of Ybor City, from which the participation of Black Cubans and the Martí-Maceo Society have been actively excluded or ignored. The main issues related to contemporary Afro- Cuban identity in Tampa and which will be examined in my dissertation, include the changing …

Queering Cognition: Extended Minds And Sociotechnologically Hybridized Gender, Michele Merritt

USF Tampa Graduate Theses and Dissertations

In the last forty years, significant developments in neuroscience, psychology, and robotic technology have been cause for major trend changes in the philosophy of mind. One such shift has been the reallocation of focus from entirely brain-centered theories of mind to more embodied, embedded, and even extended answers to the questions,

what are cognitive processes and where do we find such phenomena? Given that hypotheses such as Clark and Chalmers‘ (1998) Extended Mind or Hutto‘s (2006) Radical Enactivism, systematically undermine the organism-bound, internal, and static pictures of minds and allow instead for the distribution of cognitive processes among brains, bodies, …

Body Depilation Among Women And Men: The Association Of Body Hair Reduction Or Removal With Body Satisfaction, Appearance Comparison, Body Image Disturbance, And Body Dysmorphic Disorder Symptomatology, Michael Scott Boroughs

USF Tampa Graduate Theses and Dissertations

Body depilation, or the reduction or removal of body hair, is a relatively new area of research inquiry. Although women in many industrialized cultures have engaged in depilation for several decades, this behavior has been documented only recently among men. Though originally thought to be widely practiced by women and only a small proportion of men, including athletes or bodybuilders, recent studies suggest that more men engage in body depilation than previously hypothesized. In fact, one recent study estimated the prevalence of men's body depilation at 83.7% which suggests that men are depilating at rates similar to women. Nevertheless sparse …

Ocbs Gone Bad: The Moderating Roles Of Burnout And Role Overload, Kevin Loo

USF Tampa Graduate Theses and Dissertations

Previous literature has typically assumed that organizational citizenship behaviors (OCBs) are beneficial to both employees and organizations. Researchers have begun to question this assumption. This paper seeks to identify situations when OCBs are detrimental to employees or organizations. Specifically, two variables (burnout and role overload) are hypothesized to moderate the relationship between OCBs and outcomes (job satisfaction, turnover intentions, and task performance), such that when burnout and role overload are high, negative outcomes occur. Moderated regression was used to test the hypotheses. There was little evidence for burnout as a moderator, but interactions involving role overload were significant; however, the …
