Perceived Barriers To Breast Cancer Screening: A Comparison Of African American And Caucasian Women, Natalie E. Bastien

USF Tampa Graduate Theses and Dissertations

Although the incidence of breast cancer is high among Caucasian women, African American women continue to experience higher breast cancer mortality and lower survival rates in comparison to Caucasian women of the same age and cancer stage (Thomas, 2004). Research regarding breast cancer screening among ethnic minority women from lower socioeconomic groups is extensive, but there is a lack of research that investigates barriers to breast cancer screening among African American women of higher socioeconomic status. The purpose of this study was to compare health beliefs of African American and Caucasian women regarding perceived barriers to breast cancer screening.

Comparison Of The Use Of Single And Multiple Oxidants On The Generation Of Particulate Matter In Water Distribution Systems Derived From Groundwater Sources Containing Hydrogen Sulfide And Dissolved Organics, Rochelle J. Minnis

USF Tampa Graduate Theses and Dissertations

Due to increasingly stringent regulations, concerns about disinfection byproduct formation, and the need for improved control of distribution system water quality, there has been a shift towards the use of alternative disinfectants and oxidants in the production of drinking water. Technologies that modify water chemistry, such as hydrogen peroxide, UV irradiation, chlorine and/or chloramines may result in the generation of mineral and organic precipitates. Turbidity provides an indirect measure of the presence of particles by evaluating the light scattering properties of water. Turbidity levels are currently not monitored or regulated in treated groundwater.

An important water quality parameter that influences …

Predicting Obesity From Four Eating Behaviors, Tovah Yanover

USF Tampa Graduate Theses and Dissertations

Obesity is a growing problem in the United States. Research into the causes, treatment, and prevention of obesity is vital. One past study examined four eating behaviors in relation to obesity: eating beyond satiety, snacking, night eating, and feeling hungry within three hours of eating. Only eating beyond satiety was associated with obesity. The present study examined these same eating behaviors while correcting some of the flaws of the previous study. Using a cross-sectional design, university undergraduates reported on the frequency of the above-named eating behaviors. Current weight and height were collected. Multiple regression analyses determined that eating beyond satiety …

Age-Related Differences In Cocaine Place Conditioning And Cocaine-Induced Dopamine, Kimberly A. Badanich

USF Tampa Graduate Theses and Dissertations

In humans, adolescent exposure to illicit drugs predicts the onset of adult drug abuse and suggests that early drug use potentiates adolescent vulnerability to drug addiction. In experiment 1, it was hypothesized that adolescent rats would show a CPP for a low cocaine dose if in fact adolescents are more vulnerable to cocaine's rewarding effects. Place preferences were measured in early adolescent [postnatal day (PND) 35], late adolescent (PND 45) and young adult (PND 60) rats by injecting either 0, 5 or 20 mg/kg cocaine and conditioning them to environmental cues in a 2-chamber place conditioning apparatus. Significant cocaine preferences …

Arterial Perfusion Detection Method By Synchronous Detection, Yohan Prevot

USF Tampa Graduate Theses and Dissertations

The pressure ulcer is a well-known clinical problem that has plagued many patients in acute-care hospitals and chronic-care facilities. The pressure ulcer has the potential to diminish the quality of a patient's life by hindering the person's physical and emotional well-being. In addition, pressure ulcers are a high-cost problem. Past studies have shown that costs related to the treatment of pressure ulcers have reached 1.335 billion dollars a year in the United States alone.

A pressure ulcer is defined as a lesion created by unrelieved pressure, which causes tissue ischemia and subsequently damages the underlying tissue. This sequence of events …

Development And Implementation Of A Dsp Based Air Detector System To Prevent Embolism During Hemodialysis Therapy, Nhat Nguyen

USF Tampa Graduate Theses and Dissertations

This thesis describes the design of a DSP based air detector system to prevent air embolism during Hemodialysis, which is a treatment option for kidney failure disease. Hemodialysis consists of removing blood from the body, filtering and treating the blood to remove toxic substances such as wastes and fluids, reestablishing proper chemical levels in the blood and returning the processed blood to the body. The functions of hemodialysis are performed through the use of a dialyzer, which is also known as an artificial kidney. During hemodialysis small air bubbles may infiltrate the tubing used during the therapy and combine to …

Chromosome Missegregation In Alzheimer’S Disease Caused By Presenilin 1, Debrah I. Boeras

USF Tampa Graduate Theses and Dissertations

Mutations in the presenilin 1 gene account for most early-onset familial Alzheimer's disease (FAD). The presenilins and AD may also be related through a common involvement in the cell cycle. Here we report that one important aspect of the cell cycle---proper chromosome segregation---is dependent on presenilin function and therefore may be involved in AD pathogenesis. Specifically we find that FAD mutations in presenilin 1 (M146L and M146V) lead to chromosome missegregation and aneuploidy in vivo and in vitro: 1) Both metaphase chromosome analysis and in situ hybridization reveal significant aneuploidy in the lymphocytes and neurons of PS-1 transgenic mice. 2) …

Exploring The Role Of Social Support In Heterosexual Women’S Use And Receipt Of Non-Lethal Intimate Partner Violence, Kathryn A. Branch

USF Tampa Graduate Theses and Dissertations

The concept of social support has been found to be a protective factor in women's intimate partner violence victimization. However, little is known about the relationship between women's social support and their intimate partner violence perpetration. Research evidence demonstrates that women's perpetration of violence is surprisingly frequent, particularly in women younger than age 30. This study investigated the role of social support in heterosexual women's use and receipt of non-lethal aggression against an intimate partner among 673 female college students. The implications of these findings for research and practice are discussed.

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 …

Modeling Hurricane Evacuation Vulnerability: A Case Study Of Pinellas County, Florida, Raymond A. Miller Jr.

USF Tampa Graduate Theses and Dissertations

Determining where people are most likely to suffer losses and have difficulty in evacuating from a hurricane is important to developing a hurricane response strategy. This thesis proposes a methodology for modeling and assessing evacuation vulnerability to a specific hurricane and applies this method to study Pinellas County, Florida.

The vulnerability of Pinellas County to evacuation problems and the degree of loss that may be suffered from a hurricane is quantified in the Hurricane Evacuation Vulnerability Index. This index is the sum of three indices that represent social, transportation, and geophysical aspects of hazards research. Social vulnerability is assessed with …

The Concurrent Development Scheduling Problem (Cdsp), Leroy W. Paul

The concurrent development (CD) project is defined as the concurrent development of both hardware and software that is integrated together later for a deliverable product. The CD Scheduling Problem (CDSP) is defined as most CD baseline project schedules being developed today are overly optimistic. That is, they finish late. This study researches those techniques being used today to produce CD project schedules and looks for ways to close the gap between the baseline project schedule and reality. In Chapter 1, the CDSP is introduced. In Chapter 2, a review is made of published works. A review is also made of …

Investigating Turnover Intention Among Emergency Communication Specialists, Yufan Liu

USF Tampa Graduate Theses and Dissertations

This study tested a model that uses job stressors, equity sensitivity, perceived organizational justice, and job satisfaction to explain turnover intention and organizational citizenship behavior (OCB). An online survey was distributed to emergency communication specialists from 14 emergency communication centers in Florida. The supervisors in these emergency communication centers were asked to rate their employees on OCB. Responses to the survey and the OCB ratings were analyzed using structural equation modeling to evaluate the fit of a theoretical model to those data. Results showed that the model fit the data reasonably well and nearly all the hypotheses were supported. Specifically, …

Third Grade Retention And The Florida Comprehensive Assessment Test: An Exploratory Study, Heather A. Powell

USF Tampa Graduate Theses and Dissertations

Literacy is a growing national concern, resulting in federal legislation (e.g., No Child Left Behind Act) instituting higher accountability for states and schools with regard to reading instruction and remediation. As a result, Floridas statewide measure of achievement, the Florida Comprehensive Assessment Test (FCAT) is now tied to retention decisions in third grade as part of the new pupil progression plan in the state. In its first year of implementation (2003), 23% of third-grade students failed the FCAT and over 28,000 were retained.

Research has consistently shown retention to be a negative experience for children; even when academic gains are …

An Empirical Examination Of Job Stress And Management Of Emotionally-Based Behavior: Frontline Social Service Personnel Perspective, Doreen Sams

USF Tampa Graduate Theses and Dissertations

Frontline service personnel (FSP) play an invaluable role in the marketing mix by directly influencing the customers perception of both the service organization as well as the service quality during the face-to-face delivery service encounter (Ashforth and Humphrey 1993). The purpose of this dissertation is to examine how sources of job stress for FSP such as perceived customer demands, role ambiguity, role conflict, role overload, and emotional labor and various mediators such as job autonomy, emotional intelligence, and emotion-focused coping directly and indirectly influence job stress and outcome variables such as attitudes, behaviors, physical consequences, emotional exhaustion, job performance, and …

Effects Of Long-Term Administration Of Caffeine In A Mouse Model For Alzheimer’S Disease, William Schleif

USF Tampa Graduate Theses and Dissertations

A recent epidemiological study suggested that higher caffeine intake reduces the risk of Alzheimer's disease (AD). Caffeine, a widely consumed stimulatory drug, is a non-selective adenosine receptor antagonist that has been shown to increase plasma adenosine levels in rodents. To determine any long-term protective effects of caffeine in a controlled longitudinal study, caffeine was added to the drinking water of APP_sw transgenic (Tg) mice between 4 and 9 1/2 months of age, with behavioral testing done during the last 6 weeks of treatment. The average daily intake of caffeine per mouse (1.5 mg) was the human equivalent of 5 …

Molecular Subtyping And Antibiotic Resistance Analysis Of Salmonella Species, Aparna Tatavarthy

USF Tampa Graduate Theses and Dissertations

The genus Salmonella, comprised of 2400 serotypes, is one of the leading causes of foodborne illnesses in the US and has been used for the deliberate contamination of food. A rapid system for detection, isolation, typing and antibiotic susceptibility profiling is essential for diagnosis and source tracking in natural outbreaks or a bioterrorism event. Pure culture is essential for molecular typing and antibiotic resistance testing. The virulence and the resistance mechanisms of Salmonella are rapidly evolving and many are still unexplained. The first aim of the study was to rapidly detect and isolate Salmonella from intentionally contaminated food. The …

An Exploration Of The Lumbar Loads And Affective Responses To Lumbar Pain On Lower Limb Amputees Who Use A Prosthesis, Tracy Ann Perrotti

USF Tampa Graduate Theses and Dissertations

80% of the American population experiences back pain and it is the most common cause of limited activity in people of age 45 and under. Determining the reasons for back pain and developing new ways to treat it have been extensively researched over the past decade. However, very little research has been done on low back pain of amputees.

There are four million existing amputees living in America and 250,000 people become new amputees each year. 70% of this group is lower limb amputees and a large number use a prosthesis of some kind to aid in the functions of …

Automatic Attention To Aggression Cues And Alcohol Cues Using A Dichotic Listening Task And A Parafoveal Visual Task, Michelle Edington Levasseur

USF Tampa Graduate Theses and Dissertations

Ongoing investigations of drunken aggression tend to focus on 1) situational cues, and 2) individual variables such as personality traits. This study investigated the hypothesis that an undergraduates attention would be pulled toward a nonconscious presentation of aggression stimuli, especially in the presence of alcohol cues, and especially if he or she was high on trait anger [as measured using the State Trait Anger Expression Inventory (STAXI); Spielberger, 1988] and had high expectancies for behaving aggressively while drinking alcohol [as measured using the Expectancy Questionnaire for Alcohol and Aggression Lo Dose (EQAAL); Epps, Hunter, LeVasseur, Steinberg, and Hancock, unpublished manuscript]. …

Microfinance In Neoliberal Times: The Experience Of An Egyptian Ngo, Sarah A. Tobin

USF Tampa Graduate Theses and Dissertations

Development non-governmental organizations (NGOs) are under immense pressure to adhere to the programs and methods put forth by external donors, particularly if the NGOs rely on the funding to sustain their own organizations. Those external donors that represent neoliberal ideologies and enforce neoliberal practices, particularly in the area of microfinance, maintain a power that most recipient NGOs cannot evade. This becomes a difficult position for the NGOs to navigate as they try to accomplish good work in their communities. This research project is a study into the experience of one NGO, the Egyptian Development Organization (EDO), as it implemented microfinance …

Sexual Functioning In Breast Cancer Survivors, Heidi M. King

USF Tampa Graduate Theses and Dissertations

Breast cancer diagnosis and treatment has been suggested to effect sexual functioning. Little is known about how breast cancer patients compare to women without a history of cancer on measures of sexual functioning, as well as the psychological and physical factors may contribute to these difficulties. To address these issues, 71 breast cancer patients and 40 of their nominated friends were recruited and served as participants. All women received and returned via the mail measures on general background information, depression, fatigue, marital satisfaction, body image, vaginal symptoms, and sexual functioning. All the psychological and physical variables assessed correlated with a …

Monte Carlo Simulations As A Tool To Optimize Target Detection By Auv/Rov Laser Line Scanners, Martin Alejandro Montes

USF Tampa Graduate Theses and Dissertations

The widespread use of laser line scanners (LLS) aboard unmanned underwater vehicles in the last decade has opened a unique window to a series of ecological and military applications. Variability of underwater light fields and complexity of light contributions reaching the receiver pose a challenge for target detection of LLS under different environmental conditions. The interference of photons not originating at the target (e.g. water path, bottom) can often be minimized (e.g., time-gated systems) but not excluded. Radiative transfer models were developed to better discriminate noise components from signal contributions at the receiver for two continuous LLS: Real-time Ocean Bottom …

Stress And Cognitive Performance In Older Adults, Christopher B. Rosnick

USF Tampa Graduate Theses and Dissertations

The current dissertation sought to examine stress in three different, but overlapping, ways. The first study examined how self-reported negative life events, in the aggregate and individually, are associated with cognitive performance. The results suggested that there was no significant relationship between the aggregate measures of self-reported negative life events and cognitive performance. On the other hand, several individual negative life events were associated with cognitive functioning. The findings support previous research indicating that using estimates of individual stressors rather than aggregate measures of stressors increases the predictive validity of stress measurement.

The second study assessed the cross-sectional and longitudinal …

Expanding The Science Of Successful Aging: Older Adults Living In Continuing Care Retirement Communities (Ccrcs), Kathryn H. Petrossi

USF Tampa Graduate Theses and Dissertations

Rowe and Kahns theory of successful aging identifies three main components of aging successfully: reducing the risk of disease and disability, maintaining high cognitive and physical function, and engagement with life. While there is compelling evidence that suggests the legitimacy of this concept in the 50-75 year old community dwelling population, three areas of expansion are necessary: 1.) programmatic research; 2.) extending the existing research samples to include older samples and those living in continuing care retirement communities (CCRCs); and 3.) the integration of data collection and analysis to move beyond investigation of just one successful aging outcome to include …

Changes In The Perception And Sense Of Self Of Individuals With Aphasia: An Ethnographic Study, Erline Vieira Nakano

USF Tampa Graduate Theses and Dissertations

Little is known about the perceived changes in identity and sense of self in individuals with aphasia. Seminal research using qualitative methods and personal narratives has been conducted in England regarding the experience of living with aphasia (see for instance Parr, Byng, Gilpin & Ireland, 1999; Parr, Duchan & Pound, 2003; Byng, Pound & Hewitt, 2004), but the use of such methodologies is still emergent in the United States. In addition, despite the great achievements of the disabilities movement in countries such as the U.S. and the U.K., individuals with aphasia have remained largely at the margins due to the …

Tardigrade Evolution And Ecology, Phillip Brent Nichols

USF Tampa Graduate Theses and Dissertations

A character data set suitable for cladistic analysis of tardigrades at the family level was developed. The data matrix consisted of 50 morphological characters from 15 families of tardigrades and was analyzed by maximum parsimony. Kinorhynchs, loriciferans and gastrotrichs were used as outgroups. The results agree with the currently accepted hypothesis that Eutardigrada and Heterotardigrada are distinct monophyletic groups. Among the eutardigrades, Eoyhypsibiidae was found to be a sister group to Macrobiotidae + Hypsibiidae, while Milnesiidae was the basal eutardigrade family. The basal heterotardigrade family was found to be Oreellidae. Echiniscoideans grouped with some traditional Arthrotardigrada (Renaudarctidae, Coronarctidae + Batillipedidae) …
