USF Tampa Graduate Theses and Dissertations

A system consisting of a GPS-enabled phone and a database has been designed and implemented. This system is capable of recording the route traveled by a user and determining the mode of transport (walk, bicycle, car or bus) used. The Java code running in the GPS-enabled phone automatically records location data, determines critical locations for the trip, and transmits the locations to a central database using the wireless capabilities of the phone. As the route information arrives at the database, it is processed by the mode detection algorithm that determines the mode of transportation being used by the individual for …

Asperger Syndrome: A Case Study On One Family’S Understanding, Ben Graffam

USF Tampa Graduate Theses and Dissertations

This study explored the way members of one family understand the presence of developmental delays, especially Asperger Syndrome, in the children of that family. Specifically the study sought to glean how each parent constructed individual understanding of the presence of Asperger Syndrome in their twin, 13 year-old boys. It also sought to explore how each twin experienced the phenomenon of being labeled a child with Asperger Syndrome, and how their experiences affected their growing understanding of the syndrome. A third son, 10 years old, with PDD-NOS, was also a central focus in this study in that he also created and …

Educational Outcomes For Children With Early-Onset Behavior Problems, Allison Gibson

USF Tampa Graduate Theses and Dissertations

Research has consistently shown a greater likelihood of negative outcomes later in life for children with early-onset behavior problems. Understanding the educational outcomes for these children is essential information that can help educators and families to provide targeted interventions in an effort to positively impact these at-risk children’s school experiences. The current study used archival data and a causal comparative research design to examine the educational outcomes (academic achievement, suspension rates, retention rates, and dropout rates/failure to complete high school) for children identified as at-risk for early-onset behavior problems in grades 1 through 3 for a cohort of children in …

Attenuation Of Bromobenzene-Induced Hepatotoxicity By Poly(Adp-Ribose) Polymerase Inhibitors, Kelly Waggoner Hall

USF Tampa Graduate Theses and Dissertations

Previous studies have shown extensive cellular damage can activate poly(ADP-ribose) polymerase-1 (PARP-1) and cause a rapid decrease in the levels of NAD+ and ATP, thereby preventing apoptosis and promoting necrosis and inflammation. The purpose of this study was to extend previous observations that inhibitors of PARP-1 could alter acetaminophen and carbon tetrachloride-induced hepatotoxicity. Bromobenzene (BB) a glutathione dependent hepatotoxicant was tested. Groups of male mice were treated with a single dosage of 112mg/kg (0.075 ml/kg) BB by the intraperitoneal (ip) route. All animals were maintained in a controlled environment and provided food and water ad libitum. This dosage of BB …

Development Of A Dna Vaccine Against Streptococcus Mutans: A Novel Approach To Immunization Against Dental Caries, Thomas Han

USF Tampa Graduate Theses and Dissertations

Streptococcus mutans is the main causative agent of dental caries, which is a widespread infectious disease. A number of surface molecules are involved in the pathogenicity of this organism, including adherence and aggregation factors. The wallassociated protein A (WapA) of Streptococcus mutans GS-5 was previously demonstrated to be a sucrose-dependent adherence and aggregation factor, and is a larger precursor to extracellular antigen A (AgA), a candidate antigen for a dental caries vaccine.

The full-length wapA gene and a C-terminal truncated version agA encoding the AgA were cloned into the mammalian expression vector pcDNA 3.1/V5/His-TOPO. The above constructs were …

The main hypotheses of the study were that the full-page design option would yield significantly better outcomes in both categories of interest.

The study employed a mixed-method design, generating both quantitative and qualitative data. The main phase of the study was …

Reducing Pollutants In Industrial Stormwater Runoff: Improved Water Quality Protection Using Prioritized Facility Regulation, Lindsay M. Griffen

USF Tampa Graduate Theses and Dissertations

Stormwater pollutants originating from industrial facilities can lead to degraded water quality, even in residentially dominated regions of the country. The National Pollutant Discharge Elimination System permit program regulates stormwater pollutants generated at industrial sites using Multi-Sector General Permits (Generic permits) for industrial facilities and a permit requirement for Municipal Separate Storm Sewer System (MS4) operators. All industrial facilities within 11 broad categories of industry are responsible for self-identifying the need to comply with the Generic permit, and subsequently, implementing self-selected pollution prevention strategies. MS4 operators are required to identify and inspect “high risk” industrial and commercial facilities that may …

Fat Commentary And Fat Humor Presented In Visual Media: A Content Analysis, Susan Himes

USF Tampa Graduate Theses and Dissertations

In order to examine the phenomenon of fat messages presented through visual media, a content analysis was used to quantify and categorize fat-specific commentary. Fat commentary vignettes were identified using a targeted sampling procedure, and 135 scenes were excised from movies and TV shows. The material was coded by trained raters. Reliability indices were uniformly high for the seven categories (% agreement ranged from .90-.98; kappas ranged from .66-.94). Results indicated that fat commentary and fat humor is often verbal, directed toward another person, and is often presented directly in the presence of the overweight target. Results also indicated that …

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 …

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 …

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 …

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 …

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 …

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 …

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) …

Speech-Language Pathologists’ Professional Efficacy Beliefs About Assessing The Language Skills Of Bilingual/Bicultural/Bidialectal Students, Karen Patricia Harris

USF Tampa Graduate Theses and Dissertations

Like educators, speech-language pathologists can anticipate working with culturally and linguistically diverse students and their families. Data reported from the Study of Personnel Needs in Special Education (SPeNSE), 1999-2000, revealed that during the years 1999-2000 speech-language pathologists caseloads included students from various culturally and linguistically diverse groups (U.S. Department of Education, Office of Special Education Programs, 2001). Furthermore, on average, more than one-fourth of students seen by speech-language pathologists were from a culturally and/or linguistically diverse group than their own and 8.8% were English language learners (U.S. Department of Education, 2001). Thus, guaranteeing a highly qualified pool of speech-language pathologists …

USF Tampa Graduate Theses and Dissertations

Relations among job stressors, leadership style, emotional reactions to work,counterproductive work behavior (CWB), and autonomy were investigated. Participants representing a wide variety of jobs were surveyed. Results indicate that transactional leadership style is related to negative emotions and occurrence of CWB. Relationships between variables were mediated by emotions.

Neuroinflammation In Alzheimer’S Disease: Characterization And Modification Of The Response Of Transgenic Mice To Intrahippocampal Lipopolysaccharide Administration, Donna Lorraine Herber

USF Tampa Graduate Theses and Dissertations

Alzheimers disease (AD) is pathologically characterized by amyloid plaques, neurofibrillary tangles, inflammation, and neurodegeneration. According to the amyloid hypothesis of AD, the central mediating event of the disease is the deposition of amyloid. The inflammation hypothesis of AD states that it is the inflammatory response to plaques and tangles, rather than the actual lesions, which causes the disease. Studies described here combine the two approaches into a single model. Four studies are presented using a basic protocol of intrahippocampal lipopolysaccharide (LPS) injection to stimulate inflammation in transgenic mice. The first study looked at alpha7 nicotinic receptors during the glial response …

Validation Of The Functional Assessment Of Cancer Therapy Cognitive Scale With Bone Marrow Transplant Patients, Sheri R. Jacobs

USF Tampa Graduate Theses and Dissertations

Research has demonstrated that cancer patients report problems with cognitive functioning related to their cancer and their cancer treatments. Cognitive complaints refer to subjective reports of problems such as decreased memory, attention, concentration, and language skills. These problems with cognitive functioning can interfere with a person’s quality of life. The current measures of cognitive complaints have poor or unknown psychometric properties. Therefore, the present study sought to examine the psychometric properties of a newly developed measure of cognitive complaints for cancer patients, the Functional Assessment of Cancer Therapy Cognitive Scale (FACT-Cog). Eighty-two patients were administered a comprehensive battery of neuropsychological …
