“This Isn’T Like Diphtheria, You Know?”: The Sociocultural Context Of Human Papillomavirus Immunization, Potential Mandates, And Narratives Of Risk Among, Hannah Louise Helmy

USF Tampa Graduate Theses and Dissertations

Many in the biomedical community have praised the recently released Human Papillomavirus (HPV) vaccine, Gardasil, for having the potential to significantly reduce the disease burden of cervical cancer and genital warts. However, complex intersections of ideology, morality, and politics have made this new vaccine considerably contested, particularly as public debate has turned to the ethics of state-mandated HPV vaccination for 11-12 year old girls. Subsequently, the extent to which mandatory vaccinations are accepted by parents and implications regarding the infringement of these coercive measures on their rights to make health care decisions for their children has become powerfully positioned in …

School As A Center For Community: Establishing Neighborhood Identity Through Public Space And Educational Facility, Fred Goykhman

USF Tampa Graduate Theses and Dissertations

“Safety is an opportunity for people to open their minds” -Jin Baek, 2008

For my thesis I will design an education facility. That education facility will strive to meet with today's security needs and will provide a safe-feeling place for growth. In identifying the problem, I found two main causes for the described conditions in today's schools. They are improper adaptation and uniform building type.

Improper adaptation has to do with surface applications, rather than integrating with the social fabric of the school's communal requirements. Unfortunate incidents have caused the solutions to heightened security around schools to be fortressing and …

Effects Of Age And Hearing Loss On Perception Of Dynamic Speech Cues, Mei-Wa Tam Szeto

USF Tampa Graduate Theses and Dissertations

Older listeners, both with and without hearing loss, often complain of difficulty understanding conversational speech. One reason for such difficulty may be a decreased ability to process the rapid changes in intensity, frequency, or temporal information that serve to differentiate speech sounds. Two important cues for the identification of stop consonants are the duration of the interruption of airflow (i.e., closure duration) and rapid spectral changes following the release of closure.

Many researchers have shown that age and hearing loss affect a listener's cue weighting strategies and trading relationship between spectral and temporal cues. The study of trading relationships between …

The Biomechanics And Evolution Of Shark Teeth, Lisa Beth Whitenack

USF Tampa Graduate Theses and Dissertations

Measuring the effects of morphology on performance, and performance on fitness, is necessary to gain a full picture of selection, adaptation, ecology, and evolution. The performance of an organism's feeding apparatus, of which teeth are an integral part, has obvious implications for its fitness and survival. Extant shark teeth encompass a wide variety of shapes, and are often ascribed qualitative functions without any biomechanical testing, employing terminology such as gripping, piercing, crushing, cutting, or tearing. Additionally, teeth also comprise the vast majority of the fossil record of sharks. Therefore to understand the evolution of the shark feeding mechanism, we must …

Blank Power: The Social And Political Criticism Of Blank Fiction And Cinema, Ashley Minix Donnelly

USF Tampa Graduate Theses and Dissertations

This dissertation explores a style of literature known as "blank" fiction that became popular in the United States in the mid-1980s, focusing on its stark, limited form, its minimal plots, its focus on commodification, and its scenes of graphic violence. The author presents the argument that filmmakers were producing pieces of cinema during the same time period that are similar in both form and content to the works of blank fiction. These films are a part of a style she labels "blank" cinema.

Blank fiction and cinema are politically charged and highly critical of the social and political situation in …

Crack Patterns In Thin Films And X-Ray Optics Thermal Deformations, Grygoriy A. Kravchenko

USF Tampa Graduate Theses and Dissertations

Thin films and multilayers are widely used in many applications, ranging from X-ray optics to microelectronic devices. In service, the X-ray optics elements are exposed to the X-ray beam, which heats up the structure resulting in the thermal deformations, and consequently in distortions of the reflective surface. In addition, the excessive heating may activate interdiffusion in the multilayers coatings and result in degradation of their reflective performance and even film cracking. Therefore, analysis of the thermally-induced deformations and stresses in the X-ray optical elements is important.

The presented work is organized in two major parts. The first part examines formation …

Monocytes As Gene Therapy Vectors For The Treatment Of Alzheimer’S Disease, Lori Ann Lebson

USF Tampa Graduate Theses and Dissertations

The accumulation of amyloid-ß; protein (Aß) in Alzheimer's disease (AD) is a well known pathological event. Decreasing the production or increasing the degradation of Aß; is therefore thought to serve as a potential therapeutic intervention in AD. Recent in vitro and in vivo studies have suggested that certain proteases may be involved in the catabolism of Aß; and defects in the degradation of Aß; could contribute to AD disease progression. Studies implicating the homing of monocytes to regions of CNS damage have led to the idea that it may be possible to use genetically modified monocytes to carry exogenous genes …

Characterizing The In-Vitro Morphology And Growth Kinetics Of Intermediate Amyloid Aggregates, Shannon E. Hill

USF Tampa Graduate Theses and Dissertations

The mechanisms linking deposits of insoluble fibrils of amyloid proteins to the debilitating neuronal cell death characteristic of neurodegenerative diseases remain enigmatic. Recent findings suggest that transiently formed intermediate aggregates, and not the prominent neuronal plaques, represent the principal toxic agent. Evaluating the neurotoxicity of intermediate aggregates, however, requires unambiguous characterization of all aggregate structures present, their relative distributions, and how they evolve in time. Hen-egg white lysozyme represents an attractive model for studying intermediate aggregate formation since it is an extensively characterized globular protein, and its human variants can lead to systemic amyloidosis.

Combining in-situ dynamic light scattering (DLS) …

Copper Doped Window Layer For Cdse Solar Cells, Sheetal Kumar Chanda

USF Tampa Graduate Theses and Dissertations

CdSe solar cells with ZnTe as the window layer deposited by CSS process have shown V_oc's around 630mV. However the currents were very low and also the voltages were not meeting the desired objectives. To improve the performance the contact energy at the ZnTe/Cu interface should be minimized by doping the window layer.

Thermal evaporation was used to deposit ZnTe to have more control over the composition of the film. Initial experiments were done by depositing Cu doped ZnTe films on plain glass by co-evaporating both ZnTe and Cu. The conductivity was in the order of 10e3 which …

The downtown core is also separated from its neighboring residential areas by an area of vacant land that holds in it the potential to become a gateway into the city. On a macro scale the city has grown to be separated from the Tampa Bay area due to the lack of a mass transit system.

The goal of this project is to create a new "new urbanism" in which transit and …

High-Level Synthesis Framework For Crosstalk Minimization In Vlsi Asics, Hariharan Sankaran

USF Tampa Graduate Theses and Dissertations

Capacitive crosstalk noise can affect the delay of a switching signal or induce a glitch on a static signal causing timing violations or chip failure. Crosstalk noise depends on coupling parasitics, driver strength, signal timing characteristics, and signal transition patterns. Layout level crosstalk analysis techniques are generally pessimistic and computationally expensive for large designs due to lack of design flexibility at lower-levels of design hierarchy. The architectural decisions such as type of interconnect architecture, number of storage and execution units, network of communicating units, data bus width, etc., have a major impact on the quality of design attributes such as …

Public Perceptions Of The Separation Of Church And State, Donald Foster
