Perseverative Cognition, Cognitive Load, And Distraction In Recovery From Stress, Alvin B. Jin

USF Tampa Graduate Theses and Dissertations

Perseverative cognition is the repetitive cognitive representation of a stressor, which includes the concepts of worry and rumination. These thoughts delay post-stress cardiovascular recovery, which may lead to an increased risk for cardiovascular disease. This may be due to the negative emotional content of perseverative cognition or because it involves cognitive effort. The aim of this study was to identify the unique influences of negative emotional content and cognitive effort during recovery. Participants (N = 120) were given a demanding task purportedly as a measure of intelligence and then given false negative feedback. Immediately following, participants engaged in one of …

The Conservation And Ecology Of Carnivorous Plants, David Jennings

USF Tampa Graduate Theses and Dissertations

As discussed in Chapter 1, although our understanding of the ecology and evolution of carnivorous plants has greatly improved in recent years, many fundamental questions remain unanswered. Unfortunately, at the present time, many carnivorous plants are increasingly threatened by anthropogenic activities. Indeed, over half of the carnivorous plant species assessed by the International Union for the Conservation of Nature (IUCN) are listed as `threatened', but the threats to carnivorous plants have not previously been quantified. In Chapter 2, I quantified the conservation threats to carnivorous plant taxa worldwide by searching peer-reviewed literature, and found data on the threats to 48 …

When Does Fidelity Matter? An Evaluation Of Two Medical Simulation Methods, Nneka Joseph

USF Tampa Graduate Theses and Dissertations

Job or task simulations are used in training when the use of the real task is dangerous or expensive, such as flying aircraft or surgery. This study focused on comparing two types of simulations used in assessments during a Clinical Performance Examination of third-year medical students: computer enhanced mannequins and standardized patients. Each type of simulation has advantages, but little empirical work exists to guide the use of different types of simulation for training and evaluating different aspects of performance. This study analyzed performance scores for different competencies as well as the reliability and validity of the different simulation types. …

Biodegradation Of Bisphenol-A And 17b-Estradiol In Soil Mesocosms Under Alternating Aerobic/Anoxic/Anaerobic Conditions, Won-Seok Kim

USF Tampa Graduate Theses and Dissertations

Soil-aquifer treatment (SAT) has been proposed as a method for reusing treated municipal wastewater. SAT is characterized by alternating cycles of aerobic and anaerobic conditions in the subsurface, in response to alternating cycles of flooding and drainage of a surface impoundment. It is not yet known how these alternating redox conditions affect the removal of potentially harmful endocrine-disrupting compounds (EDCs) from treated effluent.

The overall objective of my doctoral research is to determine the fate of EDCs in alternating aerobic/anoxic/anaerobic conditions under simulated SAT conditions. To assess the fate of EDCs in simulated SAT conditions, I first had to develop …

Goal Compatibility And Emotional Intensity: An Experimental Study Of Graphic Images In Strategic Communication, Lauren Marie Klinger

USF Tampa Graduate Theses and Dissertations

The purpose of this quantitative study is to examine receiver variables involved in strategic communications and to look specifically at the use of graphic images in strategic communication materials. It argues that any complete, general model of persuasion effects will include both goal compatibility and emotional determinants. It argues that some influential theories used in strategic communications scholarship, including the situational theory of publics and the elaboration likelihood model, are incomplete because they have omitted these variables. This study also tests variables related to willingness to communicate, behavioral intention, and attitude towards the organization. These variables are drawn from prominent, …

Talking With Als Patients: An Exploratory Study Of Patient Attitudes Toward Mass Messages About Als, Kamden Kuhn

USF Tampa Graduate Theses and Dissertations

This study examines the attitudes and opinions of ALS patients toward mass messages about their condition. Six focus groups of ALS patient support groups viewed and responded to public relations messages, charity advertisements, and a news story. Results suggest that mass messages remind participants of the need for public ALS awareness. Participants also said they shared in the narratives and identify closely with the characters in the messages they viewed, and participants expressed concern with disease depictions. These concerns included a tension between positive and realistic portrayals, identification of message inaccuracies, and a desire for more specific disease information. The …

Associate Degrees In Health Related Occupations As Predictors Of Success In Physician Assistant Programs, David E. Kotun

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to determine if applicants who had an associate degree in the health sciences prior to acceptance to a physician assistant program would do better than those applicants without an associate degree in the health sciences on three measures of success of physician assistant education. The three measures of success used were graduation rates, scores on the Physician Assistant Knowledge Rating and Assessment Tool (PACKRAT), and performance on the national certifying exam, the Physician Assistant National Certification Examination (PANCE).

Gender Differences In Lung Cancer Treatment And Survival, Margaret Anne Kowski

USF Tampa Graduate Theses and Dissertations

The objectives of this research were to test treatment and survival differences between women and men with lung cancer as there is minimal investigation in the literature. Three research questions were developed with statistical testing for gender differences based on similar cancer type, stage, treatment assignment and survival. Data for 44,863 primary lung cancer cases were collected from eight U.S. state-based cancer registries to investigate the research questions. The lung cancer incidence data included the morphological cell-types of adenocarcinoma (AC); squamous cell carcinoma (SCC); large cell carcinoma (LCC) and small cell carcinoma (SCC). Stage, grade, treatment type, as well as, …

Usf's Coverage Of Women's Athletics: A Census Of The Usf Athletics Home Web Page, Laura Ann Lebeau

USF Tampa Graduate Theses and Dissertations

This study examines the coverage of women’s athletics at USF provided through photographic representations on the university’s Athletics Internet home web page during the 2009–2010 academic year. Findings from this census of five areas that comprise the USF Athletics Internet home web page revealed that, consistent with recent research on coverage of female athletes and women’s athletics on university web pages, women, compared to men, were underrepresented in the majority of the five areas of the home page analyzed. The difference in the number of overall total photographs of women and men was not that large—48% and 52%, respectively, not …

Assessment Of The Dependence Of Ventilation Image Calculation From 4d-Ct On Deformation And Ventilation Algorithms, Kujtim Latifi

USF Tampa Graduate Theses and Dissertations

Ventilation imaging using 4D-CT is a convenient and cost effective functional imaging methodology which might be of value in radiotherapy treatment planning to spare functional lung volumes. To calculate ventilation imaging from 4D-CT we must use deformable image registration (DIR). This study validates the DIR methods and investigates the dependence of calculated ventilation on DIR methods and ventilation algorithms.

The first hypothesis is if ventilation algorithms are robust then they will be insensitive to the precise DIR used provided the DIR is accurate. The second hypothesis is that the change in Houndsfield Unit (HU) method is less dependent on the …

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis was to explore the origins, formulation, course and outcome of the Intergovernmental Committee for Political Refugees meeting (better known as the Evian Conference) of July 1938. Special emphasis was placed on contemporary and later historical assessments of this assembly which represented the first international cooperative attempt to solve an acute refugee crisis. A general review followed by a more detailed evaluation was made of existing official and un-official accounts of the meeting utilizing both public records, private diaries, books, newspapers, journals and other periodicals for the period of January 1, 1938 through December 31, 1939. …

Evaluating The Effects Of Beach Nourishment On Loggerhead Sea Turtle (Caretta Caretta) Nesting In Pinellas County, Florida, Corey R. Leonard Ozan

USF Tampa Graduate Theses and Dissertations

The health of Florida's beaches are vital to the survival of loggerhead sea turtles (Caretta caretta), as nearly half of the world's loggerheads nest on the states beaches. Many of the beaches utilized by the turtles have undergone nourishment projects in hopes of combating erosion of the shoreline, protecting beachfront property, and creating more suitable beaches for tourism. Although it is argued that beach nourishment benefits sea turtles by providing more nesting habitat, the effects of the Pinellas County nourishment projects on loggerhead nesting are unknown. Beach nourishment can alter the compaction, moisture content, and temperature of the sand, all …

Bone Marrow Transplant Nurses' Attitudes About Caring For Patients Who Are Near The End Of Life: A Quality Improvement Project, Leslie Lauersdorf

USF Tampa Graduate Theses and Dissertations

In oncology setting, there is a range of emotions felt by patients and nurses alike such as helplessness, anger, sadness and anxiety; and this is especially the case as patients near the end of life. The literature shows there is an interest in nurses' attitudes toward caring for patients who are near the end of life. This project examines the overall attitude of Bone Marrow Transplant (BMT) nurses' attitudes toward caring for patients who are near the end of life using the Frommelt Attitudes Toward Care of the Dying Scale (FATCOD) and a Demographic Data Sheet. This project investigated the …

Responding To Tobacco Craving: Acceptance Versus Suppression, Erika B. Litvin

USF Tampa Graduate Theses and Dissertations

Most treatments for substance use disorders (SUDs) are based on a model that craving is a primary cause of relapse, and therefore they emphasize skills for preventing and reducing craving. Acceptance and Commitment Therapy (ACT) provides a theoretical rationale for "acceptance" of drug-related thoughts and cravings, and proscribes suppression, a more intuitive and commonly used coping strategy. However, it remains largely unknown whether various coping strategies differentially affect craving intensity, drug use behavior, or other relevant outcomes during a craving episode. Using a randomized, between-subjects design (acceptance-based coping, suppression-based coping, or no coping instructions/control), the current study compared the effect …

That Is Bad! This Is Good: Morality As Constructed By Viewers Of Television Reality Programs, Joseph Charles Losasso

USF Tampa Graduate Theses and Dissertations

Reality shows that feature people going about their presumed daily lives are not base entertainment. Internet message boards about reality programs are sites where moral work happens. Viewers write about the appearance and actions of show characters and construct moral lessons. Through naturally occurring data produced by fans of these shows, I find that viewers generally express a traditional heteronormative morality around class and gender through stating moral lessons, explaining what is wrong with the characters, or through ridicule and praise.

Performance Assessment Of Predicted Heat Strain In High Heat Stress, Ronald Eugene Long

USF Tampa Graduate Theses and Dissertations

Heat stress is a common physical agent associated with many occupations. The most commonly used method of assessing heat stress exposure is an empirical method using the Wet Bulb Globe Temperature Index but his method is limited in its ability to parse out individual contributors to the heat stress. The International Organization for Standardization (ISO) published a rational model called Predicted Heat Strain (PHS) in 2004, and rational methods have the advantage of separating out the individual pathways for heat exchange. The objective of this research was a performance assessment of the current PHS model. This experimental design consisted of …

Transition Experiences Of Adolescent Survivors Of Childhood Cancer: A Qualitative Investigation, Alana Delores Lopez

USF Tampa Graduate Theses and Dissertations

Adolescent survivors of childhood cancer are a growing population with unique needs as they face a combination of challenges associated with normal development and returning to life after treatment completion (Wakefield et al., 2010). One specific need identified in the research literature includes the effective delivery of transitional care and planning (Hewitt, Greenfield, & Stovall, 2005). It has been suggested that the provision of transition care and planning can help facilitate the shift from one phase of care to another and promote positive transition experiences (National Cancer Institute, 2008). The shift from off-treatment to post-treatment and school reintegration have been …

Framing 10/12 And 3/11 In American And European News, Andrea Lypka

USF Tampa Graduate Theses and Dissertations

This media analysis of the incidents in Bali in 2002 (10/12) and Madrid in 2004 (3/11) reveals the black and white portrayal of these attacks in western news through the localization of international terrorism occurrences, pro-government perspective, and internalization of U.S. policies. The Old Europe and New Europe debate further fractures the European press. Such rhetoric perpetuates the "us versus them" schism by contrasting the goals of the alleged perpetrators with the western values of democracy and freedom. Governmental sources remain central news sources during these crises. In addition, 9/11, war on terrorism, and fear from further attacks dominate news …

Internet Use And Economic Development: Evidence And Policy Implications, Joseph J. Macdougald

USF Tampa Graduate Theses and Dissertations

This dissertation explores how Internet use impacts four different measures of economic development using several econometric techniques on multi-country panel data. The economic development outcomes investigated are: per capita GDP, per capita export revenues, per capita market capitalization, and societal well-being as measured by the United Nations Human Development Index (HDI). Data from the World Bank, the International Telecommunication Union, and the United Nations –covering 202 countries over the period 1996 to 2007– are combined to allow for empirical investigation using dynamic panel data and finite mixture model estimation techniques on the total sample and subsamples stratified by country income …

Numeracy, Cancer Risk Perceptions, And Self-Protective Behaviors Among U.S. Adults, Teri Malo

USF Tampa Graduate Theses and Dissertations

Individuals have become more involved in health-related decisions, in part due to an unprecedented access to information that can be used to enhance both physical and mental health. Much of this health-related information is presented in a numerical format; unfortunately, research suggests many Americans may not possess the literacy skills necessary to comprehend numerical health-related information. More research needs to be conducted to examine numeracy and its role in cancer risk perceptions, and how those risk perceptions relate to cancer self-protective behaviors. The purpose of the current study was to: (a) examine socio-demographic variables associated with numeracy, (b) determine which …

Repeated Binge Pattern Ethanol Administration During Adolescence Or Adulthood: Long-Term Changes In Voluntary Ethanol Intake And Mesolimbic Dopamine Functionality In Male Rats, Antoniette Michelle Maldonado-Devincci

USF Tampa Graduate Theses and Dissertations

Binge alcohol consumption is a rising concern in the United States, especially among adolescents as during this developmental period alcohol use is usually initiated and has been shown to cause detrimental effects on brain structure and function. These findings have been established through the use of binge models in animals, where animals are repeatedly administered high doses of ethanol typically over a period of three or four days. While such work has examined the effects of a four-day and repeated three-day binge, there has been almost no work conducted aimed at investigating the long-term behavioral and neurochemical and/or functional consequences …

School-Wide Pbs: The Link Between Action Planning And Outcomes, Stephanie Angelique Martinez

USF Tampa Graduate Theses and Dissertations

Most school based initiatives are not implemented long-term and do not reach sustainability (McDermott, 2000; Mirel, 1994; Rice & Malen, 2003). Schools are implementing School-Wide Positive Behavior Support (SWPBS) as an initiative to target social emotional development and behavior. Schools that have implemented SWPBS have experienced decreases in rate of Office Discipline Referrals (ODR), In-School Suspension (ISS) and Out-of-School Suspension (OSS) (e.g. Bohanon et al., 2006; Childs et al., 2009; Lassen et al., 2006). Research has also shown that schools that implement with a higher degree of fidelity have better outcomes (Childs et al., 2009; Florida's Positive Behavior Support Project, …

The Role Of Microvascular Complications In The Relationship Between Glycemic Control And Depressive Symptomatology In Patients With Type 1 Diabetes: A Mediational Study, Laura Lynn Mayhew

USF Tampa Graduate Theses and Dissertations

People with diabetes are at double the risk of developing depression. Depression is associated with increased morbidity and mortality in people with diabetes. Levels of A1c have been linked to microvascular complications (e.g., retinopathy, nephropathy, and neuropathy) as well as depression. The interrelationship between A1c, microvascular complications, and depression has not previously been investigated in a comprehensive model, and a better understanding of the nature of these associations is needed. Preliminary analyses test the assumption that A1c mediates the relationship between group assignment in the Diabetes Control and Complications Trial (DCCT) and microvascular complications. The primary purpose of the study …

A Swmm-5 Model Of A Denitrifying Bioretention System To Estimate Nitrogen Removal From Stormwater Runoff, Michelle D. Masi

USF Tampa Graduate Theses and Dissertations

This research estimates nitrogen removal from stormwater runoff using a denitrifying bioretention system using the USEPA Storm Water Management Model Version 5 (SWMM-5). SWMM-5 has been used to help planners make better decisions since its development in 1971. A conventional bioretention system is a type of Low Impact Development (LID) technology, which designed without a media layer specifically for achieving nitrogen removal. More recently studies have showed that high TN removal efficiencies are possible when incorporating a denitrification media layer. These systems are known as denitrifying bioretention systems, or alternative bioretention systems. LID projects are currently being designed and developed …

Understanding The Psychosocial Aspects Of Waterpipe Smoking Among College Students, Mary Pautler Martinasek

USF Tampa Graduate Theses and Dissertations

Waterpipe tobacco smoking has migrated from being a custom of some cultures to becoming a staple around college campuses. The social nature and flavored tobacco encourage initiation in this tobacco naïve age group.

The study was a sequential mixed method design, employing primary data collection and analysis of a random sample of university students who live on campus at a single university. The study involved observations (N=6), intercept interviews with smokers and nonsmokers (N=63), three focus groups (N=31), and an online survey (N=288).

Findings were centered on the constructs of the Theory of Reasoned Action by Ajzen and Fishbein (1975), …

Natural Product Drug Discovery Against Tropical Diseases, Wai Sheung Ma

USF Tampa Graduate Theses and Dissertations

This dissertation describes the isolation of secondary metabolites from natural origins through a series of chromatographic techniques and spectrometric characterization in the effort of drug discovery. The isolated compounds obtained were used as drug leads against tropical diseases, namely malaria and leishmaniasis. While first chapter offers an introduction on the use of a natural product by itself as an effective therapeutic and its role on inspiring the discovery of new drugs, the later chapters will concentrate on isolation and characterization of bioactive natural products from an Antarctic sponge and mangrove endophytic fungi during the dissertation work.

The second chapter describes …

A Gay Savior: Reducing Anti-Gay Feelings With Gay Male Kindness Following Ostracism, Kenneth Michniewicz

USF Tampa Graduate Theses and Dissertations

Social scientists have extensively examined ways of reducing negative feelings toward minority groups. However, no research has examined the ability for passive ostracism, the implicit exclusion of an individual by one's peers, to reduce such negative feelings despite evidence that such exclusion can yield similar positive benefits. The present study sought to address this deficit in the literature by exploring whether or not implicit ostracism by one's peers can cause a kind gesture by a stigmatized minority group member (gay men) to improve general perceptions of the associated group. A sample of 211 undergraduate students from the University of South …

A House But Not A Home? Measuring "Householdness" In The Daily Lives Of Monticello's "Nail Boys", Shannon Lee Mcvey

USF Tampa Graduate Theses and Dissertations

Monticello, the plantation home of Thomas Jefferson, was also home to more than 100 African American slaves between 1771 and 1826. As many as 40 members of this community lived and worked on Mulberry Row, once a bustling avenue of residential and industrial activity adjacent to the Palladian mansion. Archaeological excavations in 1957 and 1982–-1983 uncovered the remains of Mulberry Row's nailery, where preteen and teenaged enslaved "“nail boys”" manufactured nails for internal use and sale. These excavations revealed surprisingly high amounts of domestic artifacts, particularly ceramics and glass, indicating the young nailers also may have lived inside the nailery. …

Middle School Students' Willingness To Engage In Different Types Of Activities With Peers: The Effect Of Presence Of Adhd Symptoms And Familiarity With Adhd, Melanie M. Mcmahan

USF Tampa Graduate Theses and Dissertations

In addition to the increased risk they face for social and academic problems, adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) must also contend with stigma attached to the disorder. For instance, youth prefer greater social distance from students described with ADHD symptoms than from peers with asthma (Walker, Coleman, Lee, Squire, & Friesen, 2008), and adolescents are also reluctant to engage in activities (e.g., go to the movies, study together) with a peer described with ADHD symptoms compared to peers described as obese or autistic (Law, Sinclair, & Fraser, 2007). Familiarity with individuals diagnosed with ADHD may influence adolescents' perceptions of their …

The Construction Of Adversarial Growth In The Wake Of A Hurricane, Beverly Lynn Mcclay Borawski

USF Tampa Graduate Theses and Dissertations

This study employed a qualitative approach to explore the factors that contribute to positive change and growth following a natural disaster. The qualitative methodology included narrative interviews and family group interviews that were conducted with six families in Florida that had experienced two or three hurricanes within six weeks in 2004. Narrative analysis and thematic analysis were used to discover what factors contributed to participants experiencing positive growth.

Participants described the experience of surviving and coping with the hurricane. Participants reported that preparation before a hurricane was a three-part process that involved physical, mental, and emotional preparation. Four actions were …
