Youth Character Strengths, Peer Victimization, And Well-Being: Understanding Associations Between Positive Traits, Social Experiences, And Positive Psychological Outcomes, Michael James Frank

USF Tampa Graduate Theses and Dissertations

The advent of positive psychology has increased awareness of factors that lead individuals to thrive in life, allowing for a more comprehensive model of mental health service delivery. However, while measurement and understanding of character strengths and well-being have improved over the last decade, the interaction of these factors with social risk factors is not entirely understood. The current study analyzed an archival dataset consisting of self-report data from 425 high school students, to examine the extent to which high school students' specific character strengths (i.e., social competence, self-regulation, responsibility, and empathy) are associated with positive psychological outcomes (i.e., gratitude, …

Residency Education In Preparing Adolescent And Young Adults For Transition To Adult Care: A Mixed Methods Pilot Study, Janet S. Hess

USF Tampa Graduate Theses and Dissertations

Background: There is considerable evidence that physicians lack sufficient training in facilitating transition from pediatric to adult care systems for adolescents and young adults (A/YA). While several primary care residency programs have introduced health care transition (HCT) curricula in recent years, there are few studies that assess the effectiveness of HCT teaching models.

Purpose: To assess the impact of a residency education program that uses electronic health records (EHR) and other methods to teach residents how to prepare A/YA for transition to adult care.

Methods: In a mixed methods, quasi-experimental research design, quantitative methods were used to measure change in …

Longitudinal Quantitative Analysis Of Gait And Balance In Friedreich's Ataxia, Jeannie B. Stephenson

USF Tampa Graduate Theses and Dissertations

Friedreich's Ataxia (FA) is an autosomal-recessive, neurodegenerative disease characterized by progressive lower extremity muscle weakness and sensory loss, balance deficits, limb and gait ataxia, and dysarthria. FA is considered a sensory ataxia because the dorsal root ganglia and spinal cord dorsal columns are involved early in the disease, whereas the cerebellum is affected later. Balance deficits and gait ataxia are often evaluated clinically and in research using clinical rating scales. Recently, quantitative tools such as the Biodex Balance System SD and the GAITRite Walkway System have become available to objectively assess balance and gait, respectively. However, there are limited studies …

A Study Of Pragmatic Competence: International Medical Graduates' And Patients' Negotiation Of The Treatment Phase Of Medical Encounters, Amy Fioramonte

USF Tampa Graduate Theses and Dissertations

Despite advances in medical technologies, interpersonal communication remains the primary tool physicians use to exchange information, make diagnoses, and treat patients (Cameron & Williams, 1997; Groopman, 2007; Ong, de Haes, Hoos, & Lammes, 1995). In the medical encounter effective communication between physician and patient is essential so that beneficial health and wellbeing outcomes are achieved for patients. Taking a discourse analytic approach, this study examined interactions occurring between international medical graduate (IMG) residents, attending physicians, and patients during the treatment advice phase of the supervised medical encounter. The aim of the study was to examine the co-constructed nature of the …

Not On My Street: Exploration Of Culture, Meaning And Perceptions Of Hiv Risk Among Middle Class African American Women, Corliss D. Heath

USF Tampa Graduate Theses and Dissertations

Black women remain at a higher risk for HIV infection than women of any other ethnic group. Of all new infections reported among U.S. women in 2010, 64% occurred in African Americans compared to 18% Whites and 15% Hispanic/Latina women (CDC 2013a; CDC 2014b). While the literature on HIV risk among African American women is extensive, it mostly focuses on low income, low education subgroups of women or those involved in high risk behaviors such as drug use. Very little has been done to understand the risk for HIV among college educated, middle class women who do not fit into …

Structural Processes And Local Meaning: Explanatory Models, Political Economy, And Chagas Disease In Tropical Bolivia, Colin James Forsyth

USF Tampa Graduate Theses and Dissertations

This project describes and analyzes explanatory models of Chagas disease among people in a highly endemic area of eastern Bolivia, and examines the role that cultural and structural factors play in shaping explanatory models of this disease. Dressler (2001) characterizes medical anthropology as divided between two poles; the constructivist, which focuses on the "meaning and significance that events have for people," and the structuralist, which emphasizes the relationships between the components of a given society. This project endeavors to synthesize structuralist and constructivist perspectives by understanding the interaction between structural processes and explanatory models of Chagas disease.

The research took …

The Interaction Of Feedback And Reward Contingency On Cardiovascular Reactivity During A Stressful Cognitive Task, Alvin B. Jin

USF Tampa Graduate Theses and Dissertations

Excessive sympathetic cardiovascular reactivity to stressful tasks is a risk factor for the development of cardiovascular disease (CVD). Many populations with a greater risk for CVD instead demonstrate blunted cardiovascular reactivity to stressful tasks. The motivational intensity theory identifies how motivation and effort influence sympathetic reactivity. Blunted reactivity may be a potential index of motivational dysregulation, which leads to poor behavioral decisions such as excess smoking or alcohol use, in turn increasing the risk for CVD. The current study sought to demonstrate how inhibited effort due to poor ability feedback with a low-contingency reward could directly increase the risk for …

Word Recognition In Noise Among Young And Older Listeners: A Combined Behavioral And Electrophysiological Study, Victoria Ann Williams-Sanchez

USF Tampa Graduate Theses and Dissertations

Word recognition is based on the complex interplay of bottom up processing of acoustic input and corresponding top-down processing based on linguistic redundancies (i.e., contextual cues). Friedrich and Kotz (2007) investigated the timeline of integrating top-down and bottom-up processes among young adults with normal hearing using sentences presented in quiet. As a follow-up study, also with young adults with normal hearing (Experiment 1 of this dissertation), we used sentences embedded in multi-talker background noise and found similar results to Friedrich and Kotz (2007); but, with the use of principal component analysis (PCA) unveiled additional effects of phonological and semantic integration …

Examination Of Possible Protective Effect Of Rhesus D Positive Blood Factor On Toxoplasma-Related Depressive Symptoms In Pregnancy, Lisa Lynn Parnell

USF Tampa Graduate Theses and Dissertations

Toxoplasma gondii infects approximately one third of the population worldwide. There is strong evidence that a relationship between T. gondii titer and depressive symptoms exists. There is also evidence suggesting a protective effect of RhD positive blood factor on toxoplasma-induced behavioral and personality changes. This protective effect may influence the relationship between T. gondii and prenatal depressive symptoms. The purpose of this secondary data analysis was to examine the possible protective effect of RhD positive blood factor on prenatal depressive symptoms in 56 pregnant women with T. gondii infection. The cross-sectional design was utilized to answer the question “Does positive …

Top-Down Processes In Simulated Combined Electric-Acoustic Hearing: The Effect Of Context And The Role Of Low-Frequency Cues In The Perception Of Temporally Interrupted Speech, Soo Hee Oh

USF Tampa Graduate Theses and Dissertations

In recent years, the number of unilateral cochlear implant (CI) users with functional residual-hearing has increased and bimodal hearing has become more prevalent. According to the multi-source speech perception model, both bottom-up and top-down processes are important components of speech perception in bimodal hearing. Additionally, these two components are thought to interact with each other to different degrees depending on the nature of the speech materials and the quality of the bottom-up cues. Previous studies have documented the benefits of bimodal hearing as compared with a CI alone, but most of them have focused on the importance of bottom-up, low-frequency …

Computer-Aided Structure-Based Drug Discovery: Cxcl12, P. Aeruginosa Lpxa, And The Tiam1 Pdz Domain, Emmanuel William Smith

USF Tampa Graduate Theses and Dissertations

For structure-based drug discovery, structural information of a target protein is necessary. NMR, or X-ray crystallography can provide necessary information on active site configuration that can lead a successful virtual screening campaign into identifying binders that may then be optimized into potent inhibitors. However, many challenges exist in the structure-based drug discovery cycle. For instance, structure determination of a protein of interest can many times be a daunting task. In addition, complex structure determination, which can allow essential characterization of protein-ligand interactions, is also challenging and many times impossible. Virtual screening heavily relies on such structural information, but hit-to-lead optimization …

Knowledge And Acceptance Of Hpv And The Hpv Vaccine In Young Men And Their Intention To Be Vaccinated, Brenda Renee Jasper

USF Tampa Graduate Theses and Dissertations

Sexually active young men are at high risk of contracting HPV and developing genital warts and penile/anal cancers. They contribute significantly to the incidence of HPV in women. The HPV vaccine, Gardasil, was approved in 2009 for use in preventing HPV 6 and 11 in young males ages 9 to 26. Knowledge and awareness of the virus and the vaccine is limited among young men. Promoting education and prevention measures regarding HPV and reducing personal risks to HPV is significant in narrowing the gap between acquisition of the HPV virus and cancer sequelae.

The Birth Of A Nation: The Case For A Tri-Level Analysis Of Forms Of Racial Vindication, Charles Fred Hearns

USF Tampa Graduate Theses and Dissertations

Early American film scholars often critique the relative ineffectiveness of a single literary work, protest movement or silent film to achieve racial vindication following the release of The Birth of a Nation in 1915. Thomas Cripps, for example, examines a relatively ineffective isolated attempt to counter the notions of White supremacy promoted in the film. This study makes the case for applying a non-traditional tri-level analysis when measuring the effectiveness of such attempts. The paper focuses on efforts to redeem the image and the potential of African Americans after 1915 in the Black public sphere in three concurrent vehicles: the …

The study was approached through identifying characteristics from my personal and professional background, to my interactions with the four literacy teachers and …

Muscling Consumers To Optimal Option Differentiation: The Influence Of Incidental Muscular Sensations On Option Differentiation, Courtney Szocs

USF Tampa Graduate Theses and Dissertations

Marketers often extend product lines by introducing slight variations of existing products (e.g., there are 53 varieties of Crest toothpaste, 15 varieties of Cheerios). As a result, consumers select from assortments containing relatively similar options. Unfortunately, consumers sometimes fail to differentiate among options, and instead consider the different options as similar and choose. Consequently, prior research shows that selecting from choice sets containing relatively similar options can sometimes lead to negative consequences such as decreased satisfaction. In light of these negative consequences, and given the frequency with which consumers choose from sets of similar options, it becomes important to identify …

The Physiological Effects Of Precooling Beverage Temperatures On Heat Strain In Collegiate Women Soccer Players, Taylor Welch

USF Tampa Graduate Theses and Dissertations

Precooling is a method used to decrease initial pre-exercise core temperature in order to facilitate a greater margin for heat production before a maximum core temperature is reached. The purpose of this study was to examine the differences in physiological and perceptual effects of precooling using beverages of three different temperatures: room temperature beverage (24.88 ± 1.13°C), cold beverage (6.15 ± 3.16°C) and ice slushy (-1.61 ± 0.45°C) in a hot environment (27.88 ± 0.72°C and 35.36 ± 0.83°C for wet globe bulb temperature and dry bulb temperature respectively). For all trials the environmental temperature was set to 35°C with …

Enlightenment On The Margins: The Catholic Enlightenment As Reflected In Ludovico Antonio Muratori's Il Cristianesimo Felice Nelle Missioni De' Padri Della Compagnia Di Gesù Nel Paraguai, Joshua Edward Britt

USF Tampa Graduate Theses and Dissertations

My research analyzes the way in which Ludovico Antonio Muratori portrayed marginal peoples of the New World in his Il Cristianesimo Felice nelle Missioni De' Padri della Compagnia di Gesù nel Paraguai, published in 1743. I argue that Muratori used his portrayal of the native people of Paraguay as a means to express his ideas of how to reform the Catholic Church, at a time when Catholicism was just experiencing the first waves of enlightened influence from the north. I engage with scholarship on the Enlightenment that has addressed specifically the cultural impact of what has been called the Catholic …

Developing An Animal Model Of Polysubstance Abuse In Adolescence: The Role Of Nmda Receptors In Alcohol/Cocaine Reward, Adriana Rebecca Uruena-Agnes

USF Tampa Graduate Theses and Dissertations

Repeated exposure to drugs of abuse conditions individuals to anticipate the behavioral consequences of drug use specifically in the presence of a drug-associated context. In rodents, preferences and aversions for alcohol and cocaine have been conditioned; however, the mechanisms underlying the expression of these conditioned effects remain unknown. Given that alcohol and cocaine polysubstance abuse is prevalent in young individuals, with more than 50% of these polysubstance abusers reporting to be under the age of 21, it is important to understand the mechanisms contributing to the behavioral effects of alcohol and cocaine co-dependency. Aim 1 determined if age differentially impacted …

Social-Emotional Strengths And Academic Outcomes In Kindergarten Students, Bryan B. Bander

USF Tampa Graduate Theses and Dissertations

Social-emotional competence has received increased attention as being critical to a student's success in the classroom. Social-emotional strengths are multidimensional and include assets such as social competence, self-regulation, empathy, and responsibility; however, previous research has not investigated which of these strengths contribute most to a student's academic success. Additionally, limited research has investigated the use of multiple informants (e.g., parents and teachers) to determine whose perceptions are more predictive of academic achievement in kindergarten students. This study examined the relationship between social-emotional strengths, as rated by parents and teachers on the SEARS (Merrell, 2011), and academic outcomes, using the AIMSweb …

Using An Acceptance And Commitment Training Protocol To Decrease Drug Use, Alexander Brown Mclean

USF Tampa Graduate Theses and Dissertations

Behavior analysts have had much success in affecting behavior change with individuals diagnosed with intellectual disabilities as well as those who would be considered typically developing with a variety of intervention strategies; most of which involve affecting direct acting contingencies. However, the realm of language-based psychopathology has just begun to be addressed within the field through language based, or indirect acting strategies. Acceptance and Commitment Therapy (ACT) is based on the concept of derived stimulus relations and allows for a behavior analytic treatment of language-based psychopathology. The current study was intended to test the efficacy of a brief protocol-delivered ACT …

USF Tampa Graduate Theses and Dissertations

The public use version of the National Comorbidity Survey - Replication (NCS-R) dataset was used (N = 995) to investigate risk factors for recurrent major depressive disorder (MDD) that are evident before recovery from the first major depressive episode (MDE) by comparing persons diagnosed with MDD who experienced a single MDE to persons with recurrent MDD.

Multiple logistic regression analyses assessed the independent risk of recurrent MDD for each of the following risk factors: an early age of onset (old), absence of a life stress trigger, chronic first episode, childhood parental loss, parental maltreatment, parental depression, comorbid anxiety disorder, and …

Growth Rates In Gulf Of Mexico Red Snapper, Lutjanus Campechanus, Before And After The Deepwater Horizon Blowout, Elizabeth Shea Herdter

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20^th, 2010 and released nearly 5 million barrels of crude oil into the northern Gulf of Mexico causing pollution of the water and sediment inhabited by many fishes for at least 87 days while the wellhead went uncapped. Populations of the Gulf of Mexico Red snapper, Lutjanus campechanus, an important fish to the ecology and economy in the region, exhibit affinity to shallow water oil infrastructure such as the Deepwater Horizon making them especially vulnerable to crude oil contamination. The objective of this study is to determine growth of Red …

Polycyclic Aromatic Hydrocarbon Metabolites As A Biomarker Of Exposure To Oil In Demersal Fishes Following The Deepwater Horizon Blowout, Susan Susan Snyder

USF Tampa Graduate Theses and Dissertations

The Deepwater Horizon blowout occurred on April 20th, 2010, releasing 4.9 million barrels of Louisiana crude oil into the Gulf of Mexico (GoM). Subsequent to the Deepwater Horizon blowout, sediment cores revealed oil on the northern GoM seafloor and abnormal skin lesions were seen in GoM fishes. Exposure to polycyclic aromatic hydrocarbons (PAHs), a component of crude oil, in fish has been associated with many sublethal effects, including cancer and population-level effects. Using a biomarker of exposure to PAHs, this thesis evaluates inter-species, temporal and spatial differences in exposure to hydrocarbon contamination between three species of fish with varying levels …
