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 …

Consumable Process Development For Chemical Mechanical Planarization Of Bit Patterned Media For Magnetic Storage Fabrication, Joseph T. Bonivel Jr.

USF Tampa Graduate Theses and Dissertations

As the superparamagnetic limit is reached, the magnetic storage industry looks to circumvent the barrier by implementing patterned media (PM) as a viable means to store and access data. Chemical mechanical polishing (CMP) is a semiconductor fabrication technique used to planarize surfaces and is investigated as a method to ensure that the PM is polished to surface roughness parameters that allow the magnetic read/write head to move seamlessly across the PM. Results from this research have implications in feasibility studies of utilizing CMP as the main planarization technique for PM fabrication. Benchmark data on the output parameters of the CMP …

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 …

Continuous Electrowetting Actuation Utilizing Current Rectification Properties Of Valve Metal Films, Corey M. Lynch

USF Tampa Graduate Theses and Dissertations

Electrowetting on dielectric (EWOD) is a technique for reducing the apparent contact angle of a fluid droplet, which has many promising applications in the fields of optics, digital displays, and lab-on-a-chip research. In this thesis, a design is presented for a novel single circuit device for achieving continuous droplet motion, by using the current-rectifying properties of valve metals to create diode-like behavior. This contrasts with existing designs, which require an array of individual electrodes to achieve motion in discrete steps. We are able to demonstrate continuous droplet motion across a 28mm-long test strip with an applied voltage of 303 V …

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 …

Ballistic Penetration Of A Sandbagged Redoubt Using Silica Sand And Pulverized Rubber Of Various Grain Sizes, Robert Paul Cole

USF Tampa Graduate Theses and Dissertations

The basis of this work is to find how varying the grain size of materials contained in sandbags (sand and crumb rubber) effects the ballistic penetration of the projectiles from both the 7.62x39mm (308-short), and 9mm Luger cartridges. The sandbags were stacked in a pyramidal stacking configuration according to military specifications in order to simulate a section of a sandbag barrier or redoubt as would be seen on the battlefield. The projectiles were fired at the targets, and the velocity and penetration data was recorded. The results concern both military and civilian applications alike. The 7.62x39 round was found to …

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 …

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 …

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 …

Investigating The Mode Of Action Of A Novel N-Sec-Butylthiolated Beta-Lactam Against Staphylococcus Aureus, Katherine Rose Prosen

USF Tampa Graduate Theses and Dissertations

N-sec

-butylthioloated β-lactam (NsβL) is a novel beta-lactam antimicrobial with a mechanism of action proposed to inhibit 3-oxoacyl-acyl carrier protein synthase (ACP) III (FabH), resulting in the inhibition of fatty acid synthesis. It has been suggested that NsβL inhibits FabH indirectly by inactivating coenzyme-A (CoA). CoA is an essential cofactor for numerous proteins involved in glycolysis, the citric acid cycle (TCA), and pyruvate metabolism, in addition to fatty acid biosynthesis. This study aimed to determine the effects of NsβL on a diverse array of laboratory and clinical Staphylococcus aureus isolates by analyzing the mode of resistance in spontaneous and adaptive …

Thermal Conductivity Of Soils From The Analysis Of Boring Logs, Nicole M. Pauly

USF Tampa Graduate Theses and Dissertations

Recent interest in "greener" geothermal heating and cooling systems as well as developments in the quality assurance of cast-in-place concrete foundations has heightened the need for properly assessing thermal properties of soils. Therein, the ability of a soil to diffuse or absorb heat is dependent on the surrounding conditions (e.g. mineralogy, saturation, density, and insitu temperature). Prior to this work, the primary thermal properties (conductivity and heat capacity) had no correlation to commonly used soil exploration methods and therefore formed the focus of this thesis.

Algorithms were developed in a spreadsheet platform that correlated input boring log information to thermal …

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 …

Electric-Field Effects And Interactions Of Dye–Polymer Systems, Brent Hilker

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 …

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 …

Synthesis Of Functionalized Resorcin[4]Arene Via Click Chemistry, Ali Husain

USF Tampa Graduate Theses and Dissertations

Click chemistry is a very powerful chemical strategy that overcome carbon-carbon bond with carbon-heteroatom bond by joining small units with heteroatom links (C-X-C) using spring-loaded reactants. The Cu(I)-catalyzed Huisgen 1,3-dipolar cycloaddition is a major example based on the click chemistry philosophy. This method was used for the last 10 years to join different functional groups, carbohydrates, aminoacids, polymers to calix[4]arene and resorcin[4]arene cavitands by a stable 1,2,3-triazole linkages.

Herein I describe our interest in this type of click chemistry reaction in the synthesis of dimeric capsules resorcin[4]arene via four 1,2,3-triazole linkages. Two different resorcin[4]arene derivatives were synthesized in which four …

The Green And Ampt Infiltration Model Accounting For Air Compression And Air Counterflow In The Shallow Water Table Environment: Laboratory Experiments, Yuliya Lukyanets

USF Tampa Graduate Theses and Dissertations

Water infiltration into the unsaturated zone especially in a shallow water table environment is affected by air compression ahead of the wetting front and air counterflow. Neglecting air compression in infiltration modeling can overestimate infiltration and infiltration rates, whereas not accounting for air counterflow can underestimate infiltration and infiltration rates due to unrealistic buildup of air pressure resistance ahead of the wetting front. A method, derived on the basis of the Green and Ampt (1911) infiltration model, is introduced to simulate air compression and air counterflow during infiltration into a shallow water table. The method retains the simplicity of the …

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 …
