Increasing Adolescents' Subjective Well-Being: Effects Of A Positive Psychology Intervention In Comparison To The Effects Of Therapeutic Alliance, Youth Factors, And Expectancy For Change, Jessica A. Savage

USF Tampa Graduate Theses and Dissertations

This study investigated the variance in subjective well-being (SWB) of early adolescents (n = 54) exposed to a positive psychology intervention aimed at increasing positive affect and life satisfaction as well as decreasing negative affect through intentional activities (e.g., gratitude journals, acts of kindness, use of character strengths, optimistic thinking). Understanding how to increase SWB among youth is important because of its associations with positive indicators of psychological and academic functioning. However, prior research is limited regarding interventions targeting SWB in youth and excludes the relation of common factors of therapeutic change. Based on the literature regarding therapeutic change, youth …

Generation And Application Of Antigen-Specific Induced Regulatory T Cells In Allogeneic Bone Marrow Transplantation, Kenrick Semple

USF Tampa Graduate Theses and Dissertations

CD28 co-stimulation is required for the generation of naturally occurring regulatory T cells (nTregs) in the thymus through Lck-signaling. However, high level of CD28 suppresses the generation of induced Tregs (iTregs) from naïve CD4 T cells, although underlying mechanism(s) has not been defined. Here we investigated the role of CD28-mediated signaling pathways in the suppression of Treg generation. We used a series of transgenic (Tg) mice on CD28-deficient background that bears WT CD28 or mutated CD28 in its cytosolic tail incapable of binding to Lck, PI3K or Itk. Regardless of exogenous IL-2, strong CD28 costimulation suppressed iTreg generation through Lck …

Health-Promoting Behaviors And Subjective Well-Being Among Early Adolescents, Emily J. Shaffer-Hudkins

USF Tampa Graduate Theses and Dissertations

This study investigated the specific health-promoting behaviors employed by early adolescents (n = 246) and their subjective well-being (SWB) to provide an understanding of how mental and physical wellness relate in teens. Participants self-reported on their dietary habits, physical activity, sleep hygiene, safety habits, and attitudes toward substance use. A comprehensive assessment of SWB was also gathered (i.e., global life satisfaction, positive affect, and negative affect). The researcher hypothesized that each of the five health-promoting behaviors assessed in the current study would have significant, positive correlations with the SWB of early adolescents, in that youth who reported higher levels of …

Thermophysical Characterization Of Nanofluids Through Molecular Dynamic Simulations, John Shelton

USF Tampa Graduate Theses and Dissertations

Using equilibrium molecular dynamics simulations, an analysis of the key thermophysical properties critical to heat transfer processes is performed. Replication of thermal conductivity and shear viscosity observations found in experimental investigations were performed using a theoretical nanopthesis-fluid system and a novel colloid-fluid interaction potential to investigate the key nanofluid parameters. Analysis of both the heat current (thermal conductivity) and stress (shear viscosity) autocorrelation functions have suggested that the dominant physical mechanisms for thermal and momentum transport arises from enhancements to the longitudinal and transverse acoustic modes energy transfer brought about by the increased mass ratio of the nanopthesis to the …

Feasibility Of Wearable Sensors To Determine Gait Parameters, Mario Alves Simoes

USF Tampa Graduate Theses and Dissertations

A wearable system that can be used in different settings to collect gait parameters on subjects with a mild traumatic brain injury (mTBI) would allow clinicians to collect needed data of subjects outside of the laboratory setting. Mild traumatic brain injuries stem from a number of causes such as illnesses, strokes, accidents or battlefield traumas. These injuries can cause issues with everyday tasks, such as gait, and are linked with vestibular dysfunction [1]. Different wearable sensor systems were analyzed prior to starting this study along with relevant gait parameters associated with mild traumatic brain injury. To monitor gait parameters relevant …

The study began with 217 students and ended with 158. The …

Framing Christianity: A Frame Analysis Of Fundamentalist Christianity From 2000-2009, Rebecca Mackin Sitten

USF Tampa Graduate Theses and Dissertations

This qualitative frame analysis examines how print media handles the concept of Fundamentalist Christianity. The researcher examined news reports in four prominent national newspapers over the ten-year period between 2000 and 2009 for references made to Fundamentalist Christianity. The sample is examined on the basis of Mark Silk's "topoi," a term taken from classical rhetoric meaning commonplaces or themes (1995). Silk outlines seven common topoi on which stories about religion are written, and these are utilized as a framework for this present study. While much has been written and researched on how religious groups, Fundamentalist Christians, and Evangelicals use mass …

"Show Me The Money!": A Pecuniary Explication Of William Makepeace Thackeray's Critical Journalism, Gary Simons

USF Tampa Graduate Theses and Dissertations

Scholars have heretofore under-examined William Makepeace Thackeray's early critical essays despite their potential for illuminating Victorian manners and life. Further, these essays' treatments of aesthetics, class, society, history, and politics are all influenced by the pecuniary aspects of periodical journalism and frequently expose socio-economic attitudes and realities. This study explicates the circumstances, contents, and cultural implications of Thackeray's critical essays. Compensatory payments Thackeray received are reconciled with his bibliographic record, questions regarding Thackeray's interactions with periodicals such as Punch and Fraser's Magazine answered, and a database of the payment practices of early Victorian periodicals established.

Thackeray's contributions to leading London …

Late Cretaceous Faunal Dynamics In The Western Interior Seaway: The Record From The Red Bird Section, Eastern Wyoming, Joshua Stephen Slattery

USF Tampa Graduate Theses and Dissertations

Studies examining bioevents (e.g., mass extinctions, faunal turnovers, diversification events) usually only scrutinize a short interval prior to such events, however, understanding their actual paleobiological implications requires a thorough understanding of the background conditions. The objective of this study is to document the background biodiversity dynamics in a single lithofacies of the Upper Cretaceous Pierre Shale that was deposited in an offshore setting of the Western Interior Seaway (WIS) and to place these changes into an environmental context. To assess the background biodiversity dynamics, the concretionary faunas of the Baculites eliasi through B. clinolobatus biozones of the Pierre Shale in …

The Hippocratic Corpus And Soranus Of Ephesus: Discovering Men's Minds Through Women's Bodies, Megan Michelle Slaughter

USF Tampa Graduate Theses and Dissertations

This thesis addresses what cultural influences and social circumstances shaped the works of the Hippocratic Corpus and Soranus's Gynecology. This thesis will illustrate how these medical texts are representative of how women were viewed by men in Classical Greece and Early Imperial Rome, respectively. It deals additionally with how these gynecological works in turn impacted the way in which society viewed and treated women. In particular, these medical writers' changing views of the act of conception shed light on the differing attitudes of their cultures. Thus far research on these time periods and works has focused too narrowly on one …

Transitioning From Student To Teacher In The Master-Apprentice Model Of Piano Pedagogy: An Exploratory Study Of Challenges, Solutions, Resources, Reflections, And Suggestions For The Future, Melissa Maccarelli Slawsky

USF Tampa Graduate Theses and Dissertations

While many music educators learn how to teach through teacher training programs, the standard mode of transmission in which piano teachers learn to teach applied piano is through proficiency of the instrument under the guidance of a master teacher. This tacit development of pedagogical knowledge occurs through the master-apprentice model of pedagogy. The purposes of this study were (a) to explore how piano teachers learn how to teach from, and independent of, piano pedagogy coursework, overcome challenges, and continue to add to their pedagogy knowledge, and (b) to explore topics that would be most useful in a piano pedagogy course …

Using Stratified Item Selection To Reduce The Number Of Items Rated In Standard Setting, Tiffany Nicole Smith

USF Tampa Graduate Theses and Dissertations

The primary purpose of this study was to evaluate the effectiveness of stratified item sampling in order to reduce the number of items needed in Modified Angoff standard setting studies. Representative subsets of items were extracted from a total of 30 full-length tests based upon content weights, item difficulty, and item discrimination. Cut scores obtained from various size subsets of each test were compared to the full-length test cut score as a measure of generalizability. Applied sampling results indicated that 50% of the full-length test is sufficient to obtain cut scores within one standard error of estimate (SEE) of the …

Novel Roles For The Transcriptional Repressor Prdm1 In Human Natural Killer Cells And Identification Of An Inhibitor Of Its Interacting Methyltransferase G9a, Matthew Adams Smith

USF Tampa Graduate Theses and Dissertations

The studies presented within this dissertation provide the first description of PRDM1 (also known as Blimp-1 or PRDI-BF1) function in natural killer cells. NK cells are major effectors of the innate immune response via antigen-independent cytotoxicity and link to the adaptive immune response through cytokine release. Molecular mechanisms mediating NK activation are relatively well-studied; however, much less is known about the mechanisms that restrain activation.

In the first study, the transcriptional repressor PRDM1 is shown to be a critical negative regulator of NK function. Microarray analysis was used to characterize transcriptional changes associated with cytokine-mediated activation. PRDM1 is expressed at …

Modeling And Parameter Study Of Bistable Spherical Compliant Mechanisms, Chester Smith

USF Tampa Graduate Theses and Dissertations

The bistable spherical compliant mechanism (BSCM) is a novel device capable of large, repeatable, out-of-plane motion, characteristics that are somewhat difficult to achieve with surface micromachined microelectromechanical systems. An improved pseudo-rigid-body model (PRBM) to predict the behavior of the BSCM is presented. The new model was used to analyze seven different versions of the device, each with a different compliant joint length. The new model, which adds torsion, is compared with a finite element analysis (FEA) beam model. The new model more closely approximates the results yielded by FEA than previous models used to analyze the BSCM. Future work is …

Predictors Of Body Dissatisfaction, Eating Disturbance, And Depressive Symptoms In Mothers, Steffanie Sperry

USF Tampa Graduate Theses and Dissertations

Body image, eating disturbance, and depressive symptomatology have been examined extensively in the general population. The assessment of these variables within the postpartum period has also been a target of recent research. Unfortunately, no existing studies have examined the intercorrelations among these factors in mothers of young children, despite increasing media pressure for moms to maintain a slim, pre-pregnancy body. The current study examined predictors of body dissatisfaction, eating disturbance, and depressive symptoms in mothers of children aged 0-5. Simple correlations were followed by a series of linear multiple regressions incorporating sociocultural predictors alongside covariates identified in the extant literature. …

Evolution/Creationism Controversy: Analysis Of Past And Current Policies In Public Schools And The Practice Of Allowing Students To Opt-Out Of Learning Evolution Concepts, Jacquelyn Hoffmann Speake

USF Tampa Graduate Theses and Dissertations

Recent anti-evolution legislation, in the form of Academic Freedom bills, has been introduced in many state legislatures over the last three years. The language in the proposed Academic Freedom bills may allow different interpretations of what can be taught in the science classrooms, and possibly spur parents to take advantage of their perceived parental rights to request their child be opted-out of class when the scientific theory of evolution is taught. Five research questions guided the analysis of participant responses to questions and perception statements focusing on secondary school administrators' actions, perceptions, and awareness as they relate to their decision …

USF Tampa Graduate Theses and Dissertations

Spanish Indian is a generic term that has been used repeatedly in written documents over the past three centuries to describe a range of different social, ethnic, and economic groups in the southeastern United States. In this thesis, a comparative analysis of the material culture from Cuban fishing ranchos of the eighteenth and nineteenth centuries on the west coast of Florida addresses the ways in which specific Spanish Indian artifact assemblages fit into the archaeological record. Three archaeological assemblages from known Rancho sites are detailed and analyzed. In addition, this thesis details a public archaeology project undertaken in conjunction with …

Sisters In Arms: A Case Study Of The Experiences Of Women Warriors In The United States Military, Carmen Teresa Stein-Mccormick

USF Tampa Graduate Theses and Dissertations

Presently there are few studies that describe the current experiences of women warriors relative to issues such as sexual hostility, sexual harassment, and other uncommon experiences during their military careers. Very little is known about how being a woman in a male-dominated military may affect women warriors' choices between making the military a career or returning to civilian life. With better understanding of women warriors' military experiences, mental health professionals, educators, and other human services professionals may have a better understanding of the issues that may affect women in the military. To date there are limited studies that have examined …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

This …

Indicators Of Early Adult And Current Personality In Parkinson's Disease, Kelly Sullivan

USF Tampa Graduate Theses and Dissertations

Introduction: Previous epidemiologic studies suggest that the personality of Parkinson's disease (PD) patients differs from that of controls, and laboratory evidence supports a potential common pathophysiology of personality traits and PD. One nested case-control study found that PD cases were significantly more anxious than controls before the clinical onset of the disease, and additional data suggest that certain occupations may be risk factors for the disease. Additionally, the latent period that precedes the onset of motor symptoms of PD is unknown.

Objectives: The objectives of this study were to evaluate the association of PD with objective indicators of current and …

The Role Of Contextual Associations In The Selection Of Objects, Noah Patrick Sulman

USF Tampa Graduate Theses and Dissertations

This paper describes a sequence of experiments addressing basic questions about the control of visual attention and the relationship between attention and object recognition. This work reviews compelling findings addressing attentional control on the basis of high-level perceptual properties. In five experiments observers were presented with a rapid sequence of object photographs and instructed to either detect or selectively encode a verbally cued object category. When these object categories (e.g. "baseball") were preceded by contextual images associated with a given object category (e.g. "baseball diamond"), observers were less likely to accurately report information about the target item. This effect obtained …

The Abjection Of The Pythia, Alaina Dyann Tackitt

USF Tampa Graduate Theses and Dissertations

Recent academic research has garnered considerable popular interest on the matter of whether the Pythia, the Oracle of Delphi, was high. Current findings aim to prove that vapors emitted from beneath the tripod on which the Pythia prophesied were intoxicating, thereby causing her frenzied state and statements. Contemporary scientists’ intense interest in proving that the Pythia was not prophetic evokes the question of why the once widely accepted, now generally rejected, idea that a female body can serve as a vessel for the words of the immortal deity holds such significance for modern science. When this curiosity is considered in …

Asymmetric Passive Dynamic Walker Used To Examine Gait Rehabilitation Methods, John Sushko

USF Tampa Graduate Theses and Dissertations

Testing gait rehabilitation devices on humans can be a difficult task, due to the effects of the neurological controls of the human body. This thesis advances the use of a passive dynamic walker (PDW) tuned to have asymmetric gait patterns similar to those with physical impairments to test rehabilitation devices. A passive dynamic walker is a multipendulum system that has a stable gait pattern when walking down a slope without any energy inputs except the forces due to gravity. A PDW model is better suited for testing rehabilitation devices because it has been shown to resemble human gait and separates …
