Standardizing The Auditory Evoked Potential Technique: Ground-Truthing Against Behavioral Conditioning In The Goldfish, Carassius Auratus, Randy J. Hill

USF Tampa Graduate Theses and Dissertations

Auditory evoked potentials (AEPs) have become commonly used to measure hearing thresholds in fish. However, it is uncertain how well AEP thresholds match behavioral hearing thresholds and what effect variability in electrode placement and tank composition has on AEPs. In the first experiment, the effect of testing tank composition and electrode placement on AEPs was determined by recording AEPs in the same individual fish in a steel and PVC cylindrical testing tank, and simultaneously recording AEPs from four locations and two different depths on each of 12 goldfish, Carassius auratus. Results from these studies show that tank composition has …

The Effects Of A Comprehensive Post-Treatment Recovery Program For Breast Cancer Survivors, Keri Ann Hockett

USF Tampa Graduate Theses and Dissertations

Background: Breast cancer and its treatment often result in side effects that persist long after treatment has ended. The increased survival rate for breast cancer has allowed for the study of the physical and psychosocial symptoms that persist into the post-treatment period. Although research has tested various interventions and demonstrated improvement in some symptoms, no standard of care exists for management of symptoms in the post- treatment period as part of the continuum of care. Objective: The aim of this research was to examine the effects of a comprehensive recovery program of education, exercise, and support for breast cancer survivors …

Multiculturalism, Public Policy, And The High School United States And American Literature Canon: A Content Analysis Of Textbooks Adopted In The State Of Florida In 1991 And 2003, Angela L. Hansen

USF Tampa Graduate Theses and Dissertations

This study compared the content of United States and American Literature textbooks adopted in Florida in 1991 and 2003 to determine any change in the inclusion of multiculturalism, as a response to public policy. Since Florida is a key adoption state, textbooks adopted would probably be reflective of national developments. To determine effects of public policy on literary selections appearing in high school United States and American literature textbooks, a variety of strategies was employed. Literary selections for each textbook and each adoption year were categorized by race and/or ethnicity and gender of the author, and genre of selections. In …

A Discourse Concerning Two New Compositions, Stanley D. Harrison

USF Tampa Graduate Theses and Dissertations

This project addresses problems for theorists of writing and composition that arose in the 1990s when capital privatizes the production of internetworked writing and starts operating in the manner of a practicing compositionist. I begin by noting that capital in the 1990s converted internetworked writing machines into fixed capital and started composing its version of the cultural form of the "social" we call the Internet. Thereafter, I argue that composition theorists can best understand the Internet, internetworked writing, and internetworked subjectivities if they regard capital as a formidable compositionist, one capable of making the machinofactured internetworked composition into a privately …

Florida's Civil War Soldiers, Jennifer J. Hawley

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis is to chronicle the actions of the soldiers of Florida during the Civil War, both within and without Florida. As there has not been a great deal written on this topic, it is hoped that this thesis will contribute to the discussion and perhaps lead others to study this field.

The soldiers of Florida during the Civil War deserve the same attention given to the soldiers from more prominent states. Those who fought for the Confederacy and stayed to defend their state often had to fight against overwhelming odds. Abandoned for a time by the …

The Position Of The Ophiuroidea Within The Phylum Echinodermata, Mary C. Harmon

USF Tampa Graduate Theses and Dissertations

Cladistic analyses of the interclass relationships of the phylum Echinodermata have not provided a phylogeny that is separately supported by both larval and adult characters. Similar to the reported incongruence with cladistic analyses, molecular analyses of ribosomal RNA (rRNA) genes have also given ambiguous results, which could be due to a number of factors. The use of short sequences, systematic errors such as long branch attraction, and mis-alignments of the data that are introduced by programs which are unsuitable for non-protein coding genes, have resulted in a controversy as to the true nature of echinoderm relationships. Historically, it is the …

Development And Initial Validation Of The Work-Family Facilitation Scale, Sheila K. Holbrook

USF Tampa Graduate Theses and Dissertations

The benefits of occupying multiple roles have typically been overlooked. One reason for this oversight is the lack of a well-established scale measuring work-family facilitation. This study developed and validated short, self-report scales of work-to-family facilitation and family-to-work facilitation. Based on conceptualizations of work and family facilitation presented in current research content domains and definitions of the constructs are presented. Work-to-family facilitation is defined as a form of role facilitation in which the experiences in the job, work skills, and emotional gratification from work makes participation in the family easier. Family-to-work facilitation is defined as a form of role facilitation …

Service-Learning Literacies: Lessons Learned From Middle School Youth, Steven Michael Hart

USF Tampa Graduate Theses and Dissertations

The dominant ideology driving the current educational reform movement positions adolescents as deficient in basic literacy skills. To address this deficiency, the trend has been to implement high-stakes standardized literacy tests and increase accountability to schools for developing basic literacy skills. Opposing this Discourse of “deficient youth,” literacy researchers have moved to adolescents’ cultural spheres of life beyond school to discover that traditional structures for teaching literacy appear to have resulted in a growing dissonance between literacies that take place within schools and those employed by youth in their personal worlds.

This research was conducted to explore how adolescents constructed …

Occupational Role Portrayals Of African-American Women On Prime-Time Television, Shani Tyhirah Jefferson

USF Tampa Graduate Theses and Dissertations

This study examined portrayals of African-American women shown in professional careers on prime-time network television during the May 2005 sweeps month. Specifically, the study compares these portrayals to actual U.S. Department of Labor workforce statistics to observe a possible similarity. Additionally, the study identifies any behavioral and conversational stereotyped attributes ascribed to AfricanAmerican female characters shown in the workplace. A quantitative content analysis of four broadcast networks (FOX, ABC, UPN, and WB) ranked by Nielsen Media as having the highest rated prime-time television programming among minority households for 2003-2004 revealed that African-American female characters on network television are over-represented in …

“The Wil Of His Wif:” Discourse, Power, And Gender In Chaucer’S The Tale Of Melibee, Sara D. Jenkins

USF Tampa Graduate Theses and Dissertations

In the Tale of Melibee, Chaucer gives us an excellent illustration of a point French theorist Michel Foucault would make centuries later: That power is something that moves and shifts between people and within institutions, that it is not fixed nor permanent, that it is used as needed toward specific ends, and that it is enacted through the medium of discourse. In Melibee, Melibee’s wife Prudence achieves a place of authority and influence in her marriage via her use of discourse, and specifically by using a more “male” way of speaking. Chaucer is often considered feminist-friendly due to …

All The News That’S Fit To Print? Media Reporting Of Environmental Protection Agency Penalties Assessed Against The Petroleum Refining Industry, 1997-2003, Melissa L. Jarrell

USF Tampa Graduate Theses and Dissertations

Although examination of the relationship between the media and crime has received considerable attention in the academic literature, only a few studies have examined news media coverage of environmental crimes. The present study examines print news media coverage of federal penalties assessed against the petroleum refining industry from 1997 to 2003. The Environmental Protection Agency initiated and/or settled 162 cases involving seventy-eight petroleum refining companies from 1997 to 2003. While a news search of the nation’s twenty-five largest newspapers produced seventy-four articles related to petroleum refining industry violations, only seventeen articles matched the EPA cases analyzed in the present study. …

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

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 …
