Thirty Year Follow-Up Of Juvenile Homicide Offenders, Norair Khachatryan

USF Tampa Graduate Theses and Dissertations

Killings by juvenile offenders have been a matter of concern in the United States since the 1980s. Although the rate of juvenile-perpetrated murders has been declining since the 1990s, it remains problematic, in that juvenile offenders account for approximately 10% of all homicide arrests. Research on recidivism of juvenile homicide offenders (JHOs) is important, due to relatively short follow-up periods in prior studies and a recent Supreme Court ruling that struck down mandatory life sentences without the possibility of parole for juveniles convicted of murder. The present study was designed to explore long-term patterns of recidivism, and particularly violent recidivism, …

Exploring The Interactive Effects Of Social Learning Theory And Psychopathy On Serious Juvenile Delinquency, Brandy Barenna Henderson

USF Tampa Graduate Theses and Dissertations

Social learning theory continues to be one of the most enduring theories of crime. Psychological criminology, on the other hand, tends to explain crime in terms of behavioral propensities. This research is specifically focused on the generality of social learning theory as it varies across a measure of criminal propensity- in this case, psychopathy. Prior studies have tested various theories with the use of measures of propensity, but the theory is rarely social learning, and the measure of propensity has never been psychopathy. The current study examines three components of social learning theory (definitions, differential association, and differential reinforcement) to …

The Role Of Social Support In The Disclosure And Recovery Process Of Rape Victims, Jessica Nicole Mitchell

USF Tampa Graduate Theses and Dissertations

Women disproportionately account for a majority of all completed and attempted rape victimizations each year in the U.S. relative to men. Female college students, in particular, have been noted as a group with the highest risk for rape. Rape among women not only has a substantial public health impact, but has been linked to a number of individual mental health and substance use problems. Despite the fact that service utilization (formal help-seeking with a counselor, mental health professional, rape crisis center, and police reporting) has been shown to deter negative sequelae of rape, few victims of rape receive assistance from …

Two Essays On Ipos And Asset Prices, Gaole Chen

USF Tampa Graduate Theses and Dissertations

In the first essay we examine the effect of concurrent lending and underwriting on IPO withdrawal, we find that IPOs underwritten by the firms’ concurrent lending banks are significantly more likely to be withdrawn. The result is robust to controlling for the common factors that affect IPO withdrawal and also for endogeneity using a propensity score matching portfolio. Our evidence suggests a cost to IPO firms’ hiring concurrent lending banks as underwriters despite the potential benefit of informational scope economies such intermediaries may provide. It is consistent with an alternative argument that a current lending and underwriting bank has less …

An Experimental Evaluation Of The Relationship Between In-Vivo Stimuli And Attentional Bias To Smoking And Food Cues Among Female Smokers, John Bernard Correa

USF Tampa Graduate Theses and Dissertations

Background: Cross-sectional and experimental research has shown that female smokers more frequently report using cigarettes to control negative affect, manage dietary restraint, and suppress body image dissatisfaction. However, there has been little research to identify cognitive mechanisms that may underlie these effects. Cross-stimulus attentional bias is one such mechanism.

Aims and Hypotheses: We hypothesized that, when compared to neutral stimuli, in-vivo appetitive stimuli would enhance motivation to obtain a particular substance. More specifically, in-vivo smoking stimuli would increase attentional bias to smoking-related pictorial cues, whereas in-vivo food stimuli would increase attention to smoking-related and food-related pictorial cues. We also hypothesized …

Examining Endorsement And Viewership Effects On The Source Credibility Of Youtubers, Stephanie Fred

USF Tampa Graduate Theses and Dissertations

The growth of YouTube has resulted in the industrialization of a platform that redefines mainstream success. Success measures such as endorsements and viewership are serving as motivational factors for YouTubers. YouTubers and brands want more views, but are those motivations effecting perception? While much research has focused on the effects that YouTube has on the brand, this study focuses on the effects that the brand has on the YouTuber. It also determines whether viewership affects YouTuber perception and whether it‟s a success measure worth using. Using the constructs of the source credibility theory, this study assessed the main effect of …

Maternal Stress, Breastmilk Igf-1, And Offspring Growth Among Breastfeeding Mothers-Infant Pairs In The Tampa Bay Area, Lauren Michelle Gottfredson

USF Tampa Graduate Theses and Dissertations

Background: Maternal stress during utero has been shown to have negative health consequences on the offspring, including low birth weight and increased risk of adult disease. Variation in breastmilk may act as an environmental cue of maternal stress and continue to program the infant during early life. This research aimed to explore the role of breastmilk on developmental programming of the infant. Specifically, to examine how breastmilk may act as a medium for the exposure of stress between the mother and the offspring, and see if variation in insulin like growth factor-1 (IGF-1) a potential mechanism for the relationship.

Mindfulness Attributes As Predictors Of Treatment Outcomes In Children Who Stutter, Jenna Lee Graepel

USF Tampa Graduate Theses and Dissertations

A recent U.S.-based survey (Boyle et al,. 2011) estimated stuttering prevalence in American children ages 3-17 years at 1.6% or 1 in 63 children. In comparison to the reported 1 in 68 school age children living with Autism Spectrum Disorder (Centers for Disease Control and Prevention, 2010), stuttering affects nearly as many. These estimates suggest that Speech-Language Pathologist (SLPs) should increasingly develop their skill sets for identifying and providing interventions for children who stutter.

The evidence base for school-age fluency intervention, while promising, leaves much room for further development (Nippold, 2011). The majority of current interventions revolve around the traditional …

Theoretically Guided Examination Of Caregiver Strain And Its Relationship With School-Based Mental Health Services Utilization And Parent Engagement In Services, Amy Lynn Green

USF Tampa Graduate Theses and Dissertations

Broadly, the purpose of this study was to address the gaps in the knowledge base of caregiver strain through an examination of this and other theoretically related constructs in a sample of parents of high-risk youth. In the last two decades, a growing body of research has pointed to the significance of strain that can result from this caregiving experience, particularly as it relates to patterns of mental health services utilization. Despite the fact that the majority of children who receive mental health receive them from the school, few studies have examined caregiver strain in the context of school-based mental …

Neuroinflammatory Alterations Via Cd-36 In Traumatic Brain Injury, Diana G. Hernandez-Ontiveros

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) has become an increasingly unmet clinical need due to intense military conflicts worldwide. Directly impacted brain cells suffer massive death, with neighboring cells succumbing to progressive neurodegeneration accompanied by inflammatory and other secondary cell death events. Subsequent neurodegenerative events may extend to normal areas beyond the core of injury, thereby exacerbating the central nervous system’s inflammatory response to TBI. Recently CD-36 (cluster of differentiation 36/fatty acid translocase (FAT), a class B scavenger receptor of modified low-density lipoproteins (mLDLs) in macrophages, has been implicated in lipid metabolism, atherosclerosis, oxidative stress, and tissue injury in cerebral ischemia, and …

Facilitating A Transdisciplinary Approach In Teacher Education Through Multimodal Literacy And Cognitive Neuroscience, Margaret Billings Krause

USF Tampa Graduate Theses and Dissertations

This dissertation is a compilation of research and theoretical papers based on the affordances of multimodal literacies for marginalized learners and for pre-service teachers’ developing conceptualizations of literacy. Through a transdisciplinary lens, the author considers complex issues presented in traditional, print-based learning environments that potentially marginalize learners in their developing abilities to become successful participants in the multiple literacies in the real world.

Three studies focus on pre-service teachers and their developing understanding of effective literacy-related classroom practices. Chapter Three explores potential affordances of a multimodal learning environment for pre-service teachers with self-identified reading difficulties. The phenomenological study highlights differing …

The Relationship Between Nurses' Emotional Intelligence And Patient Outcomes, Mary Kutash

USF Tampa Graduate Theses and Dissertations

Heart Failure readmissions (HFR) significantly contribute to all cause hospital readmissions rates. Current evidence on the effectiveness of interventions for reduction of HFR is inconclusive. Recent research suggests that nurses’ emotional intelligence (EI) may be associated with better patient outcomes.

The purpose of this study was to examine if nurses’ EI is significantly related to HFR and if that relationship is mediated through patient satisfaction with care. One hundred and thirty six Registered Nurses were recruited from 11 in-patient units at a large teaching hospital in the south eastern United States. Two surveys were mailed to eligible participants; the Bar-On …

The Meaning Of Stories Without Meaning: A Post-Holocaust Experiment, Tori Chambers Lockler

USF Tampa Graduate Theses and Dissertations

Dissonance exists in efforts to communicate about suffering and despair. Showcasing common societal flawed reactions to despair begs for discourse to create a more communicatively healthy response. Attempting to communicate the suffering of others and feeling like I was failing at that goal led to my own suffering. Using writing as a method of personal healing created an intersection of personal narratives of suffering and victim’s narratives (which can arguable only allow for the co-opting of the story and narcissism). Grappling with the limits of writing to heal provided a lens to see the victim’s narratives in such a way …

Fear Conditioning And Extinction In Childhood Obsessive-Compulsive Disorder, Joseph F. Mcguire

USF Tampa Graduate Theses and Dissertations

Fear conditioning and extinction are central in the cognitive behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive behavioral therapy (CBT). Youth with OCD may have impairments in conditioning and extinction that carries treatment implications. The present study examined these processes using a differential conditioning paradigm. Forty-one youth (19 OCD, 22 community controls) and their parents completed a battery of clinical interviews, rating scales, and a differential conditioning task. Skin conductance response (SCR) served as the primary dependent measure across all three phases of the conditioning procedure (habituation, acquisition, and extinction). During habituation, no meaningful differences were observed between …

Tell Sir Thomas More We've Got Another Failed Attempt: Utopia And The Burning Man Project, Gracen Lila Kovacik

USF Tampa Graduate Theses and Dissertations

Burning Man, a weeklong experience in Black Rock Desert, Nevada, has become an oasis for those looking to escape the corporatized grasp of modern culture. Burning Man serves as a reprieve from judgment and allows participants to embrace and perform their inner identities. The intensions of Burning Man have been widely debated, from scholars concentrating on the rejection of consumerism to analyzing sacred space and religious connectivity for festivalgoers. What deserves further analysis, however, is the utopian nature of the event. I will explore previous utopian attempts--literary, political, etc.--and define what characteristics from those societies were present during the inception …

Half Empty/Half Full: Absence, Ethnicity, And The Question Of Identity In The United States, Ashley Josephine Martinez

USF Tampa Graduate Theses and Dissertations

This study helps us understand the complexities of transnational abandonment, and transnational abandonment in the context of Saudi heritage in particular. Based on a textual analysis of narratives on a blog by individuals abandoned by their Saudi fathers, my findings suggest that they discursively construct their identity in three ways: a) by negotiating their illegitimate status as perceived by many Saudis, and the validity of their search; b) by making sense of the absence of father and the cultural knowledge of the paternal side, while negotiating the inevitable presence of the father in many other ways and their ethnic difference; …

Sexual Functioning And Body Image In Younger Breast Cancer Survivors, Carly Lynn Paterson

USF Tampa Graduate Theses and Dissertations

Younger breast cancer survivors often report problems related to sexuality following surgical and adjuvant treatment that often lead to sexual distress and body image distress. This research was conducted as an exploratory study within a larger R01 trial with the purpose to evaluate sexual distress and body image related-distress in younger women with breast cancer and to examine the extent to which the Mindfulness-Based Stress Reduction-Breast Cancer (MBSR(BC)) was efficacious in improving distress related to sexuality, i.e. sexual distress and body image related-distress. The aims of this study were to: 1) evaluate the efficacy of the MBSR(BC) program in improving …

A Mixed Method Study Examining Synchronous-Enhanced Learning In Distance Education, Kimberly M. Wheeler

USF Tampa Graduate Theses and Dissertations

This mixed method study examined how integration of synchronous Web-based desktop conferencing affects undergraduate distance learning students' educational experience. Specifically, it compared students in one distance learning section of an introductory technology course delivered through a synchronous-enhanced mode (employing both synchronous and asynchronous tools) with students in a second section of the same distance learning course provided in the asynchronous only mode to examine variations in cognitive presence, social presence, and teaching presence through the lens of the Community of Inquiry model (Garrison, Anderson, and Archer, 2000). Additionally, this study measured perceived learning, learner-instructor interaction, and learner-learner interaction to determine …

Attentional Allocation In Language Processing In Adults Who Stutter: Erp Evidence, Wendy Lorraine Olsen

USF Tampa Graduate Theses and Dissertations

The aim of this study was to investigate how young adults who stutterer allocate attentional resources during two linguistic stages in picture naming, specifically lemma and lexeme retrieval. This study reports on behavioral and brain electrophysiological data collected during a simple auditory oddball task and a Dual Picture-Word Interference/Tone Monitoring Task.

Individual Differences In The Dopaminergic Reward System: The Effect Of Genetic Risk On Neural Reward Sensitivity And Risky Choice, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

When making decisions, individuals evaluate several possible outcomes of their choice; however, some display heightened reward sensitivity, despite the potential for future negative consequences, which can lead one to make risky choices. Rewards are processed in the mesolimbic dopamine reward system, and this system is in part modulated by genetic polymorphisms that are associated with dopamine transmission. The current study tested if genetic polymorphisms that are associated with enhanced dopamine neurotransmission will be more neurally reward sensitive, score higher on self-reported impulsivity, and make riskier choices. In a sample of 85 participants, five genetic polymorphisms were genotyped and used to …

Genetic Moderation Of Phenotypic And Neural Indicators Of Peer Influenced Risk-Taking Behavior: An Experimental Investigation, Troy Alan Webber

USF Tampa Graduate Theses and Dissertations

Risk-taking behavior (RTB) is defined as behavior involving the probability of reward with concurrent probability of some negative outcome. Peer influence is among the most robust predictors of RTB, such that greater peer influence, particularly deviant or delinquent peer influence, is associated with increased RTB. Evidence suggests that those with genetic predispositions for RTB may also be more susceptible to peer influence as a function of genotype. Given that genetic polymorphisms within the dopaminergic system have evidenced associations with various forms of RTB and delinquent peer affiliation, it is possible that these genes may interact with peer influence to predict …

Personality As A Predictor Of Occupational Safety: Does It Really Matter?, Stephanie Anne Andel

USF Tampa Graduate Theses and Dissertations

Past research demonstrates the high prevalence of occupational accidents and injuries, and therefore much work has gone into examining potential antecedents to such incidences. However, while some research has examined personality as a potential antecedent, results suggesting personality as a significant predictor of occupational safety remain inconclusive. Therefore, the purpose of the current work is to conduct a cross-sectional multi-source survey study that will take a closer look at the relationships between various personality variables and occupational safety. Essentially, the purpose of the current study is threefold: (1) to examine the relationships between two Big Five personality factors, safety locus …

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, …

Constructing An "Appropriate" Education In Florida Special Education Due Process Final Orders, Michelle Henry

USF Tampa Graduate Theses and Dissertations

This study examined how Florida administrative law judges (ALJs) constructed an appropriate education for students with disabilities in their final orders. This study utilized the Johnstone Method as a heuristic in analyzing the data. It examined the construction of an appropriate education from the implementation of PL 94-142 up to the U.S. Supreme Court decision in Board of Education v. Rowley (1975-1978), after the Rowley decision (1983-1986), and after the reauthorization of the Individual with Disabilities Education Act in 2004 (2004-2007). Each time period was examined individually and then the results were compared. The data sources included six purposively sampled …

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 …

Evaluation And Application Of Instruments Measuring Spatial Ability And Attitude For College Chemistry Students, Xiaoying Xu

USF Tampa Graduate Theses and Dissertations

Student performance in college chemistry courses remains a concern for educators seeking to help improve the future STEM workforce. Besides math ability and prior chemistry knowledge, spatial ability and attitude toward chemistry have been considered as important factors influencing college chemistry performance. This work includes five studies and uses data collected from instruments to examine the relationships of these two factors - spatial ability and attitude - with student chemistry performance, and provides psychometric evidence for using the Purdue Visualization of Rotations test (ROT) and Attitude toward the Subject of Chemistry Inventory (ASCIv2) to measure these two factors, respectively, in …

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 …

The Effects Of Collaborative Critical Thinking Training On Trust Development And Effectiveness In Virtual Teams, Mark Grichanik

USF Tampa Graduate Theses and Dissertations

Workers in modern teams that perform tasks over computer-mediated communication channels encounter challenges in building trust and performing effectively. Finding interventions to mitigate such losses could improve team performance. Collaborative critical thinking (CCT) training has the potential to improve trust, monitoring, and effectiveness in virtual teams. Using a simulated search-and-rescue task, the effects of CCT training, as compared with a control training, were evaluated in 105 three-member teams. No effects of CCT training were found on team positive or negative monitoring, team cognitive or affective trust, team efficacy, or team viability. However, teams trained in CCT reported consistently higher levels …

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 …
