Increasing Healthy Food Choices In Preschoolers Using Correspondence Training And Recruiting Natural Communities Of Reinforcement, Elyse D. Wiseman

USF Tampa Graduate Theses and Dissertations

Obesity is a contributing factor to many diseases. Unhealthy food choices are a behavior that can lead to obesity. Teaching children to make healthy food choices at an early age could lead to healthy food choices throughout a lifetime, which would mitigate potential for obesity. A number of different treatments have evaluated healthy food choices in children; however, many did not evaluate or show maintenance effects. The purpose of this study was to utilize correspondence training to acquire healthy food choices in preschoolers and to evaluate of natural communities of reinforcement as a maintenance procedure. Results showed that correspondence training …

A Canine Audience: The Effect Of Animal-Assisted Therapy On Reading Progress Among Students Identified With Learning Disabilities, Julie Omodio Griess

USF Tampa Graduate Theses and Dissertations

This study explored the use of animal-assisted therapy with students identified with a learning disability and limited reading success. Initially, reading progress was defined as the participants' comprehension rate obtained from an oral Informal Reading Inventory (IRI) passage. The nature of the Informal Reading Inventory requires the introduction of more difficult reading passages as the student's comprehension rate increases, potentially masking the overall effect of the intervention. Due to this factor and erratic student performance, which is a common characteristic of students with learning disabilities, obtaining consistent comprehension rates was difficult. Therefore, progress was defined only as total amount of …

Autonomic Reactivity And Recovery In Healthy Black, White, And Hispanic Women With And Without A Family History Of Cardiovascular Disease, Mardís Sara Karlsdóttir

USF Tampa Graduate Theses and Dissertations

Exaggerated cardiovascular reactivity and impaired recovery to psychological stress is independently related to cardiovascular disease (CVD), and may play a causal role in its development. I examined autonomic reactivity and recovery in 136 black, white, and Hispanic women who were predisposed to CVD, as indicated by a positive family history (FH+). Pre-ejection period (PEP; sympathetic) and respiratory sinus arrhythmia (RSA; parasympathetic) were measured during public speaking, mental arithmetic, and cold pressor tasks. Overall, FH+ participants exhibited greater RSA reactivity, while black participants exhibited impaired RSA recovery. These findings suggest that a hereditary predisposition for CVD is related to altered autonomic …

Prioritizing Those Who Follow: Servant Leadership, Needs Satisfaction, And Positive Employee Outcomes, Kristin N. Saboe

USF Tampa Graduate Theses and Dissertations

Servant leaders seek to fulfill the needs of followers and promote their success and well-being through a follower-centric, generative approach to leadership. This study proposes a model to describe the mediating mechanism of follower needs satisfaction, as proposed by Self-Determination Theory (SDT), for the relationship between servant leadership (SL) behaviors and employee outcomes (e.g., job performance, job attitudes, well-being, community prosocial behavior). Supervisor-subordinate dyads (N = 147 pairs) from four diverse organizations completed surveys about the supervisors' leadership behaviors and the subordinates' job experiences. Structural equation modeling and regression analyses were conducted to determine the nature of relationships between SL, …

Examining The Relationship Between Work-To-Family Conflict And Parenting Behavior, Eunae Cho

USF Tampa Graduate Theses and Dissertations

Although work-family conflict (WFC) has been of particular interest to work-family researchers, little attention has been paid to the consequences of WFC that reside in the family domain. Research on WFC and child outcomes is especially scant. The current study addresses the gap in the literature by investigating the relationship between work-interfere-with-family (WIF) and three forms of parent-child interaction behavior (PB): physical and recreational PB (PRPB), cognitive and academic-oriented PB (CAPB), and passive and maintenance-oriented PB (PMPB). The mechanism by which WIF relates to PB was further investigated by examining negative emotion as a mediator and trait guilt as a …

In three related but distinct essays, the dissertation examines the governance concept, and investigates contributing knowledge to and using knowledge from electronic repositories governed by these two mechanisms. The first essay sets the conceptual foundations of knowledge governance in repositories, and examines the salient aspects of expert- and community-governance that contribute to knowledge quality. The essay adopts an interpretive research methodology and analyzes empirical data collected from a range of organizations using …

An Anatomical Investigation Of Higher Visual Structures In The Pigeon (Columba Livia), Tadd B. Patton

USF Tampa Graduate Theses and Dissertations

Early visual processing in the avian brain has been studied extensively, the retina and midbrain in particular. However, a clear understanding of the higher visual centers in the forebrain (the telencephalon and thalamus) remains poor. Two structures located within the avian visual telencephalon, the entopallium (E) and the lateral portion of the intermediate nidopallium (NIL), merit extensive investigation based on their critical role in visual processing. The goal of the current study was to further clarify the anatomical characteristics of E and NIL. Visual information that reaches these telencephalic structures is mostly from the contralateral retina. Thus, blocking visual input …

Relationships Between Substance Use, Mental Health Problems, And Involvement In School-Based Extracurricular Activities Among High School Students, Kristelle Malval

USF Tampa Graduate Theses and Dissertations

Substance use during adolescence is associated with numerous undesirable short term and long term consequences. This study examined rates of substance use, as well as rates of elevated anxiety and depressive symptomalogy, among 138 students attending a predominantly Hispanic, low-SES high school. The current study also examined the complex relationships between adolescent substance use, mental health problems, and involvement in school-based extracurricular activities, among this ethnically diverse sample. Results included that a significant proportion of adolescents in the sample fell in the "at-risk" category for a clinical diagnosis of depression and/or anxiety disorder. Further, those students who reported smoking cigarettes …

Residential Learning Outcomes: Analysis Using The College Student Experiences Questionnaire At A Large Public Research University, Cari Murphy

USF Tampa Graduate Theses and Dissertations

The creation of learning outcomes inside and outside of the classroom on college campuses has been a growing trend based on a variety of publications which encouraged the fostering of diverse types learning and the measurement of student learning outside of the classroom (ACPA, 1994; Keeling, 2004). The creation of the learning outcomes is a positive step, however, assessment of the learning outcomes must be conducted to determine what students are learning and what areas are to be improved otherwise the learning outcomes are meaningless.

This study was conducted at a large public research university where the Department of Housing …

USF Tampa Graduate Theses and Dissertations

Using data from the Drug Use Forecasting (DUF) and the Arrestee Drug Abuse Monitoring (ADAM) programs collected by the National Institute of Justice the question whether the drug estimates of DUF, using a non-probability sample, and the drug use estimates of ADAM, using a probability sample, yield substantially different results will be explored. The following main questions will be addressed using equivalence analysis: Are there substantial differences in the DUF and ADAM samples with regard to the drug use information obtained from arrestees at nine sites across the United States? The analysis suggests that the drug use information contained in …

"In My Church We Don't Believe In Homosexuals": Queer Identity And Dominant Culture In Three Texts Of The Aids Era, Steven Cooper

USF Tampa Graduate Theses and Dissertations

My thesis seeks to examine the relationship that exists between queer selfidentification and heterosexual hegemonic/heteronormative power in three works of and about the AIDS era. Working from feminist and queer theory perspectives, I first chart the way in which a problematic identity—be that identity a non-identity of utter invisibility, a sick identity, a dangerous identity, or (most commonly) an identity of utter hedonism disconnected from any notions of attachment, affection, or love beyond the physical sexual act—has been and is still wholly adopted by some. I do this principally with a close reading of Renaud Camus' 1981 novel Tricks, …

Ac/Dc: Let There Be Hybrid Cooling, Christopher Podes

USF Tampa Graduate Theses and Dissertations

In today’s increasingly energy conscious society, the methods of providing thermal comfort to humans are constantly under scrutiny. Depending on the climate, and the comfort requirements of the occupants, buildings can be designed to heat and cool occupants with passive methods, as well as mechanical methods. In the subtropics, where buildings often need to be heated in the winter and cooled in the summer, a synthesis of these two methods would be ideal. However, there is a disconnect between the integration of passive cooling and mechanical air conditioning, in subtropical architecture.

A study of user attitudes, based out of Australia, …

Ecotourism And Water Quality: Linking Management, Activities And Sustainability Indicators In The Caribbean, Ken Darrie Thomas

USF Tampa Graduate Theses and Dissertations

Ecotourism from its genesis and founding theories has been set out to conserve and preserve the environment through sustainable operation that includes surrounding communities in efforts to reduce their poverty levels. Over the years ecotourism has been hypothesized to have departed from this ideal with several researchers, through social, qualitative analyses, have said that these non-sustainable ecotourism operations are simply due to poor management. This work sought to test this central hypothesis as a first approach to quantitatively linking ecotourism activities to management with surface water quality as the key indicator of sustainable ecotourism as a complex system through systems …

Understanding The Relationships Between Interpersonal Conflict At Work, Perceived Control, Coping, And Employee Well-Being, Erin M. Eatough

USF Tampa Graduate Theses and Dissertations

Stressors resulting from one's work life including work conditions, job characteristics, and relationships with others at work have been shown to impact employee health outcomes at both psychological and physical levels (Le Blanc, Jonge, & Schaufeli, 2008; Spector, Dwyer, & Jex, 1988). Interpersonal conflict is one prevalent workplace stressor that has been associated with poor work-related outcomes and psychological states. A cross-sectional design with multi-source data collection methods was used to measure conflict, perceptions of control, coping strategies, and both psychological and physical well-being. Overall, findings suggested that the success of coping efforts hinges on the combination of the nature …

Women’S Perceptions Of Postpartum Stress: A Narrative Analysis, Nancy Gilbert Crist

USF Tampa Graduate Theses and Dissertations

The impact of stress on the health of postpartum mothers is poorly understood. Although the postpartum period increases risk for stress related diseases such as depression and autoimmune disorders, little qualitative research has focused on women’s perceptions of postpartum stressors.

A constant comparative content analysis using Atlas.Ti was done on data collected by Groer (NIH R01 NR05000“Influence of Lactation on Postpartum Stress & Immunity) from 2001 to 2005. Women (n=127) answered the prompt, “Think of any one incident, thought, or feeling that stands out as very stressful to you and describe in as much detail as you choose.” Researcher triangulation …

To What Extent Does A Social Compact Exist Between Higher Education And Society: A Study Of Two Minnesota Universities, Laurie Woodward

USF Tampa Graduate Theses and Dissertations

This dissertation explores the nature, applicability and usefulness of social contract theory, and the resulting compact between higher education and society as a way to understand the growth and development of higher education in the United States. The goal is accomplished with an in-depth look at two different universities in the state of Minnesota at four different periods or pivotal points in the history of higher education in the United States. The underlying assumption was that if there is a social compact between higher education and society, traces of its existence would be found in the historical evidence concerning the …

Examining The Interface Between Alcohol Expectancies, Psychophysiological Reactivity To Alcohol Picture Cues, And Risk For Substance Use Disorders, Ashlee C. Carter

USF Tampa Graduate Theses and Dissertations

The study examined the overlap between cognitive and affective measures of alcohol expectancies as they related to risk for developing alcohol use disorders. It was hypothesized that cognitive-based, paper-and-pencil measures and appetitive psychophysiological reactivity to alcohol cues would correlate and independently correlate to drinking behavior in a sample of college drinkers. It was also hypothesized that genetic risk would impact the relationship between upstream and downstream expectancy measures, given that children of alcoholics displayed blunted reactivity to appetitive cues.

A sample of 137 college drinkers (67 males; mean age = 20.23 ± 1.61) reporting a range of drinking behavior (mean …

Closet Space: Investigating Gay Identity Through Advertising In Gay Media, Jonathan A. Hanna

USF Tampa Graduate Theses and Dissertations

The objective of this research was to examine advertising in gay media publications, namely, The Advocate, in order to assess how advertising corresponds with gay identity formation. This study differed from previous inquiries in that the application of hegemony theory formed the basis of the project and was used as a tool to explicate the preponderance of certain images in gay media advertising and what they signify for gay men. Likewise, a phenomenological method of analysis was applied to the advertisements in order to render them more accessible as aesthetic and literary mediums. Classifying the advertisements according to their notional …

Characterization Of An Urban Heat Island (Uhi) In The Tampa Region Of Florida, Joann Sullivan

USF Tampa Graduate Theses and Dissertations

Numerous research studies have been conducted on the modification of weather and local climate by the urban environment. In studying the urban environment effects, researchers have investigated the urban heat island (UHI), anthropogenic cloud condensation nuclei, anthropogenic heat emissions and other factors. Many of these studies used data sampling networks, while other studies relied solely on computer modeling. This research has taken an approach between the sampling network studies (which were often limited in spatial density) and the pure computer model studies (which lacked the benefits of observational data) to investigate the Tampa Bay Region UHI. The research utilized inexpensive …

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to describe and explain the perspectives of five participants representing the school district and community regarding the achievement gap between Black and White students. This study attempted to answer two major questions:

1. What are the components of their perspectives and how they are formed?

2. What beliefs support or hinder that perspective? In this study social conflict theory was used as the theoretical framework for this study, harnessing the concept of resiliency as a new paradigm shift looking at Black students and community not as "deficient" or "deficits" but implementing their unique cultural …

Three Essays On Analytical Models To Improve Early Detection Of Cancer, Chaitra Gopalappa

USF Tampa Graduate Theses and Dissertations

Development of approaches for early detection of cancer requires a comprehensive understanding of the cellular functions that lead to cancer, as well as implementing strategies for population-wide early detection. Cell functions are supported by proteins that are produced by active or expressed genes. Identifying cancer biomarkers, i.e., the genes that are expressed and the corresponding proteins present only in a cancer state of the cell, can lead to its use for early detection of cancer and for developing drugs. There are approximately 30,000 genes in the human genome producing over 500,000 proteins, thereby posing significant analytical challenges in linking …

Refusing To Go Silently: Female Wit As Combating A Culture Of Silence In Frances Burney And Elizabeth Inchbald's Texts, Megan M. Weber

USF Tampa Graduate Theses and Dissertations

In the hands of two prominent authors, Elizabeth Inchbald and Frances Burney, a critical paradox concerning female silence arises: while both authors operate very successfully in the publishing world, both do so while subverting impositions of silence, exhibiting a clear breach of propriety. An examination of Inchbald's novel A Simple Story and play Wives as they Were, Maids as they Are and Burney's novel Cecilia and play The Witlings, elucidates how each author adapts literary genres to portray female wit, exposing eighteenth-century impositions of silence in the process. By engendering female characters with the ability to employ humor as …

Analysis Of Two Strategies For Structuring Medicare Reimbursement To Maximize Profitability In Acute Care General Hospitals, James D. Barrington

USF Tampa Graduate Theses and Dissertations

The healthcare literature sometimes cites Medicare as a negative determinant of hospital profitability. However, a review of Florida acute care short-term general hospital data revealed a subset of profitable hospitals with high percentages of their revenue structure comprised of Medicare reimbursements. Some investigators might contend that these hospitals are just better managed; that hospital profitability is not related to patient mix or payer source. Although good management enhances financial health, there are perhaps other reasons why certain hospitals can become profitable with Medicare as their primary revenue source.

Research findings indicate there is wide geographic variability shown for per-capita volumes …

Neuroprotection With Anesthetics In Two Models Of Cerebral Ischemia, Rafael Eduardo Chaparro Buitrago

USF Tampa Graduate Theses and Dissertations

Neuroprotection with anesthetics has been studied for many decades; important advances in this field have modified the way Anesthesiologists treat patients in the operating room. Animal models have played an important role in the study of ischemia in the operating room. Recent studies have demonstrated that the effect of anesthetics seems to be different in different animal models. We decided to evaluate anesthetics in a well-known model of cerebral ischemia and also in hypotensive models designed by us. We used a model of cerebral ischemia (MCAO) to test anesthetics neuroprotective effect in a two-week period. Then, we used a model …

Shamanism, Spiritual Transformation And The Ethical Obligations Of The Dying Person: A Narrative Approach, Ellen W. Klein

USF Tampa Graduate Theses and Dissertations

The person experiencing chronic or protracted illness is confronted with a complex array of physical, emotional and spiritual trials. This thesis explores how chronic illness can be viewed through the lens of the shamanic experience of dismemberment and re-memberment and shows how clinical, narrative, and relational models on their own are insufficient to speak meaningfully to illness experiences, but the integration of aspects of each of these models when coupled with shamanic initiation experience creates an innovative model for patients and those with whom they are in relationship.

Struggle In The Sunshine City: The Movement For Racial Equality In St. Petersburg Florida 1955-1968, Peyton L. Jones

USF Tampa Graduate Theses and Dissertations

Recent decades have seen a shift in the focus of civil rights historiography. Building upon the exhaustive studies of national figures and events, and in search of new perspectives, many historians have concentrated on local movements often ignored or forgotten. Other than the work of a few local scholars, the civil rights movement as it occurred in St. Petersburg, Florida, has received little attention. Furthermore, the limited scholarship lacks the cohesion necessary to compare and contrast the movement with similar events throughout the state and across the nation. The story of St. Petersburg's active and significant struggle for social equality, …
