Latino Mothers’ Responsiveness And Bilingual Language Development In Young Children From 24 Months To 36 Months, Rica Ramirez

USF Tampa Graduate Theses and Dissertations

This longitudinal study examined the role maternal responsiveness had on shaping Spanish and English language development in bilingual two year-old children. Because children who are bilingual language learners are oftentimes coming from low socioeconomic families it is essential that we investigate the ways in which they develop language in order to better serve this population. Maternal responsiveness is one source in which we can examine early language development of young bilingual children. Eight Latino mother-child dyads were observed and assessed at three time points. Each observation was coded for maternal responsive behaviors. Regression and multilevel modeling was used in order …

Body As Text: Physiognomy On The Early English Stage, Curtis Le Van

USF Tampa Graduate Theses and Dissertations

My dissertation explores the presence of physiognomy, which is the reading of faces and bodily affects to determine a person’s character. I investigate plays originally produced for the early English stage, ranging from the late Middle Ages to the Restoration. In this work I argue that the bodies within the selected plays exist as texts that are to be interpreted by readers and audience members alike. While embodiment theory has done excellent work in explaining the corporeality of the pre-modern body, it does not consider the body as a textual construction. My work aims to fill such a gap. My …

Health Literacy, Depression, Anxiety, And Posttraumatic Stress Disorder As Predictors Of Biological Markers Of Immune Functioning In Youth And Young Adults With Hiv, Courtney A. Lynn

USF Tampa Graduate Theses and Dissertations

Human immunodeficiency virus (HIV) is a virus that affects the body’s immune system (Centers for Disease Control [CDC], 2016a). HIV is a worldwide epidemic and disproportionately impacts youth in the United States. Youth living with HIV (YLWH) face significant mental health problems, namely depression, anxiety, and posttraumatic stress disorder (PTSD) with rates of these disorders discrepant from those in the general population. In addition to psychological difficulties, health literacy is another factor that influences individuals with HIV and is a priority of research with adolescents (Kalichman et al., 2000; Manganello, 2008). The National HIV/AIDS Strategy: Update 2020 (White House Office …

A Motivational Interviewing Intervention To Increase Utilization Of Smoking Cessation Services Among Veterans Undergoing Substance Use Treatment, Nicole S. Menzie

USF Tampa Graduate Theses and Dissertations

Smoking remains the single most preventable cause of death worldwide and primary cause of several types of cancer, cardiovascular disease, and respiratory illness (USDHHS, 2014). Although the prevalence of smoking among the general population continues to decline, the prevalence of smoking among the veteran population remains high. In addition, the prevalence of smoking among veterans with substance and alcohol use disorders is 2 to 3 times higher than in the general population. Over the years, the VA has implemented empirically-based treatments for smoking cessation to address the cigarette smoking epidemic. These services, however, are greatly underutilized. Motivational interviewing (MI) has …

Chronic Runaway Youth: A Gender-Based Analysis, Michelle N. Jeanis

USF Tampa Graduate Theses and Dissertations

Runaway youth often face a multitude of negative experiences during their childhood, which often leads to trajectories of psychological disorder/distress, victimization, and offending. This propensity for negative life trajectories may be exacerbated by repetitive runaway behavior. Additionally, these negatives experiences may be further shaped by the gender of the youth, thus creating distinct gendered pathways to chronic runaway behavior, victimization, and offending. This study utilized a sample of youth runaways in the state of Florida (N=295) to build upon the classification/typology research on juvenile runaways by assessing the presence of latent groups of youth based on runaway frequency. In addition, …

A Landscape Of Thermal Inequity: Social Vulnerability To Urban Heat In U.S. Cities, Bruce Coffyn Mitchell

USF Tampa Graduate Theses and Dissertations

A combination of the urban heat island effect and a rising temperature baseline resulting from global climate change inequitably impacts socially vulnerable populations residing in urban areas. This dissertation examines distributional inequity of exposure to urban heat by socially disadvantaged groups and minorities in the context of climate justice. Using Cutter’s hazards-of-place model, variables indicative of social vulnerability and biophysical vulnerability are statistically tested for their associations. Biophysical vulnerability is conceptualized utilizing a urban heat risk index calculated from summer 2010 LANDSAT imagery to measure land surface temperature , structural density through the normalized difference built-up index, and vegetation abundance …

Discovering Antibacterial And Anti-Resistance Agents Targeting Multi-Drug Resistant Eskape Pathogens, Renee Fleeman

USF Tampa Graduate Theses and Dissertations

Antibiotic resistance has been a developing problem for mankind in recent decades and multi-drug resistant bacteria are now encountered that are resistant to all treatment options available. In 2014, the World Health Organization announced that this problem is driving us towards a “post-antibiotic era” that will change the face of modern medicine as we know it. If lack of novel antibiotic development and FDA approval continues, by the year 2050, 10 million people will die each year to an antimicrobial resistant bacterial infection. With lack of pharmaceutical industry involvement in developing novel antibiotics, the responsibility now lies within the academic …

Learning Style Patterns Among Special Needs Adult Students At King Saud University, Abdulrahman Alshuaibi

USF Tampa Graduate Theses and Dissertations

Few studies of learning styles among adults with special needs exist worldwide. Even though there are large numbers of adults with special needs, this population in university education has been largely ignored in educational research. Therefore, this study aimed to gather and analyze learning styles of adult special needs students and to provide data for researchers interested in the fields of learning styles, adult education, and special education. This study examined the learning style patterns among special needs adult students at King Saud University as measured by the dimensions of the Index of Learning Styles, which include active/reflective, sensing/intuitive, …

Benchmarks Of Equality? School-Wide Positive Behavior Interventions And Supports And School Discipline Risk And Disparities For Black And Hispanic Students, Christopher M. Barclay

USF Tampa Graduate Theses and Dissertations

In U.S. schools, Black and Hispanic youth receive discipline in the form of office discipline referrals and out-of-school suspensions at a rate greater than their White peers. Contributing factors to this “discipline gap” may be found across a number of ecological variables. Therefore, multifaceted and systemic interventions such as school-wide positive behavior interventions and supports (SWPBIS) should be evaluated for their effectiveness in producing more equitable school discipline rates. In light of mixed evidence for the relationship of SWPBIS with discipline equity, the purpose of this study was to examine the merits of five critical elements of SWPBIS for reducing …

Essays In Health Economics, Olga Petrova

USF Tampa Graduate Theses and Dissertations

Over the past two decades, a growing body of literature within health economics has provided evidence of the impact of fetal conditions on individual’s health and economic outcomes over the entire life course. This dissertation contributes to the field of health economics by investigating the effects of two distinct types of public policies, antimalarial interventions in sub-Saharan Africa and medical marijuana laws in the United States, on early-life health.

Chapter 1 adds to the increased understanding of the impact of in utero exposure to large-scale interventions to combat endemic diseases by examining the effects of antimalarial interventions aimed at preventing …

The Development And Validation Of The Physical Appearance Comparison Scale-3 (Pacs-3), Lauren M. Schaefer

USF Tampa Graduate Theses and Dissertations

Both theory and research implicate appearance comparison processes in the development of body image disturbance and disordered eating. Although several measures of appearance comparison exist, each has significant limitations. The Physical Appearance Comparison Scale-Revised (PACS-R) and its earlier versions are measures designed to assess the frequency of appearance comparisons among men and women. In the current study, the PACS-R was revised to (a) examine comparisons of weight/shape, muscularity, and overall physical appearance, (b) include items to assess comparisons with distal targets, (c) provide an assessment of upward versus downward comparisons, and (d) provide an assessment of the acute emotional impact …

Understanding The Experience Of Early-Onset Bipolar Disorder: A Phenomenological Study Of Emerging Adults, Kristin M. Smyth

USF Tampa Graduate Theses and Dissertations

While early-onset bipolar disorder (EOBD) has increased in prevalence, much remains to be understood about its phenomenology. Research and treatment models remain rooted in neurobiological conceptualizations of the illness that borrow heavily from models for the traditional adult-onset form of bipolar disorder. This study utilized a transcendental phenomenological design as a first step in obtaining an understanding of the lived experience of EOBD. A purposive sample of eight participants ages 18-25 participated in semi-structured interviews that elicited information on experiences of EOBD symptomatology and course of illness, stigma, experience with healthcare and treatment, and impact on identity, interpersonal relationships, and …

Examining Forty Years Of The Social Organization Of Feminisms: Ethnography Of Two Women’S Bookstores In The Us South, Mary Catherine Whitlock

USF Tampa Graduate Theses and Dissertations

At the height of their popularity in the 1990s, there were 140 feminist bookstores in the US and Canada (Onosaka 2006). Today, in 2017, there are thirteen left. Feminist bookstores began opening in the 1970s promoting ideas about lesbian separatism, woman only spaces, and nurturing a feminist community. Although many functioned as for-profit stores, many also operated community centers and non-profit organizations. Feminist bookstores provide an excellent site for scholars view decades of social movement organizing merging theory, practice, activism, and academics. As a social movement organization, feminist bookstores as are the quintessential node of academia and activism. Of the …

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb

USF Tampa Graduate Theses and Dissertations

The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models …

The Effect Of Androstenone As A Mating Prime On Drinking And Approach Behavior, Robin Tan

USF Tampa Graduate Theses and Dissertations

Recent research has shown that sexual activity may be influenced by variables suggested by evolutionary theory, such as pheromonal cues. A recent study in our laboratory indicated that female pheromones influence men’s drinking and approach behavior based on hidden pathways of behavioral influence caused by chemosensory signals. The current study sought to examine whether a link exists between male pheromones and women’s drinking and approach behavior, through the use of a possible male sex pheromone called androstenone, and sought to examine this link within the context of a women’s ovulation cycle. One hundred and three female participants were primed with …

The study involved three children, ages 2 and 3 years old who had difficulty performing household chemical safety skills at home. A multiple-baseline across participants design with an ABC sequence was used to examine the effects of the Social Story^TM and in-situ training interventions on the children’s household chemical safety skills. The investigation focused on examining whether the Social Story^TM alone would be effective in teaching targeted safety skills to …

Adverse Childhood Experiences And Their Role As Mitigators For Youthful And Non-Youthful Offenders In Capital Sentencing Cases, Jessica R. Trapassi

USF Tampa Graduate Theses and Dissertations

Adverse childhood experiences (ACEs) and their role as mitigators in capital sentencing is an important, yet relatively unexplored, topic in criminological literature. Using data from the North Carolina Capital Sentencing Project, this study explores the role of ACEs as mitigating factors for youthful and non-youthful capital offenders: whether youthful offenders are less likely to be sentenced to death, whether or not ACEs are effective as mitigating factors, and whether ACE mitigators are more effective for youthful or non-youthful offenders. Results show that youthful capital offenders are less likely to be sentenced to death than adult capital offenders, and while ACE …

Treatment Of Food Selectivity: An Evaluation Of Video Modeling Of Contingencies, Erin O'Connor

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to evaluate the effectiveness of video modeling of contingencies alone and/or combined with direct exposure to the contingencies in the treatment of food selectivity. Treatment procedures included sequentially introducing videos in which models consumed nonpreferred food, were exposed to differential reinforcement, or exposed to escape extinction and differential reinforcement. In addition, participants were exposed to differential reinforcement. Results indicated video modeling of differential reinforcement plus differential reinforcement may be effective at increasing consumption of some nonpreferred foods, but the results were not replicated across all foods. For one participant, consumption of one food increased …

Female Incarceration And Prison Social Order: An Examination Of Gender Differences In Prison Misconduct And In-Prison Punishments, Elisa L. Toman

USF Tampa Graduate Theses and Dissertations

The dramatic increase in the U.S. prison population has renewed scholarly interest in the prison experience. Researchers have built upon and extended classic theories of inmate behavior to better understand the mechanisms that lead to inmate violence and misbehavior. Yet, scholars still consider what happens to inmates inside of prison a “black box,” due to limited systematic assessments of the prison experience. This body of scholarship is also limited by its narrow focus on males, as theories of inmate behavior have been developed around male experiences and, in turn, ignore the possibility that gender may influence prison life. Feminist theory …

Associations Between Ethnic Identity, Academic Efficacy, Achievement Goals And School Belonging Among Early Adolescents, Leah Bonilla

USF Tampa Graduate Theses and Dissertations

The United States is experiencing a major shift in the population as more students who are considered ethnic minorities enter the school system. These students are at an increased risk for school failure due to language barriers, challenges with experiencing potential discrimination, and debating their identities across two cultural contexts. Although students who are considered ethnic minorities risk many potential stressors, the literature has shown that ethnic identity is a factor that facilitates positive academic adjustment and engagement among this population. Previous literature has also documented mixed findings regarding the relationship between ethnic identity and school outcomes. The current study …

Chemotherapy-Induced Alopecia And Quality-Of-Life: Ovarian And Uterine Cancer Patients And The Aesthetics Of Disease, Meredith L. Clements

USF Tampa Graduate Theses and Dissertations

This study is an examination of ovarian and uterine cancer patients’ perceptions of chemotherapy-induced alopecia and how it impacts quality-of-life over the course of chemotherapy. The chapters in this dissertation address the following research questions: How do ovarian and uterine cancer patients communicate about their experiences of alopecia over the course of chemotherapy? How does chemotherapy-induced alopecia influence patients’ understandings of quality-of-life? Longitudinal interviews were conducted with a patient population of twenty-three, and each patient was interviewed at least twice over the course of chemotherapy. The data set was composed of fifty-five interviews, and a thematic analysis was performed across …

Patterns In Words Related To Dna Rearrangements, Lukas Nabergall

USF Tampa Graduate Theses and Dissertations

Patterns, sequences of variables, have traditionally only been studied when morphic images of them appear as factors in words. In this thesis, we initiate a study of patterns in words that appear as subwords of words. We say that a pattern appears in a word if each pattern variable can be morphically mapped to a factor in the word. To gain insight into the complexity of, and similarities between, words, we define pattern indices and distances between two words relative a given set of patterns. The distance is defined as the minimum number of pattern insertions and/or removals that transform …

Age Of Alcohol Initiation And Reward Processes In A Current Alcohol Drinking Sample, Claire M. Gorey

USF Tampa Graduate Theses and Dissertations

Earlier ages of alcohol initiation have been associated with an increased vulnerability for Alcohol Use Disorder and general risk taking behaviors beyond genetic influence. Reward processes, including reward anticipation (pleasure before receiving alcohol/general reward), reward learning (how quickly one pairs a stimulus with alcohol/general reward), and reward consummation (pleasure when receiving alcohol/general reward), have been implicated as potential mechanisms accounting for this vulnerability. However, no careful bio-behavioral research has been conducted on the effect of age of alcohol initiation on general and alcohol-related reward processes. Using Event Related Potentials (ERPs), the current study addressed this gap in a sample of …

Parent Perceptions Of Treatment Effectiveness And Attendance Rates In A Behavioral Parent Training Program: Do They Predict Treatment Outcomes For Children?, Natalie A. Hofmann Leedy

USF Tampa Graduate Theses and Dissertations

Young children who display disruptive behaviors are at risk for negative outcomes in later development such as school dropout, early pregnancy, and unemployment (Bradshaw, Schaeffer, Petras, & Ialongo, 2010). For this reason, it is imperative parents of children with disruptive behaviors seek early intervention to reduce problem behaviors and prevent negative effects (Breitenstein, Hill, & Gross, 2009). Parent behavioral training interventions are effective for reducing problem behaviors in young children. Attrition from parent training interventions, however, is a common problem that reduces positive outcomes for children with challenging behaviors (Kazdin, Holland, & Crowley, 1997; Prinz & Miller, 1994). Barriers to …

Students With Disabilities At Risk: Predictors Of On-Time Graduation, Kelli S. Henson

USF Tampa Graduate Theses and Dissertations

The deleterious effects of not completing high school in the United States and around the world in the current monetary, societal, and employment climate make efforts toward increasing graduation rates an imperative. The impetus for educational reform for improving graduation rates is even more salient for students with disabilities who graduate at lower rates than their peers without disabilities (Stetser & Stillwell, 2014). To provide the multi-tiered systems of support (MTSS) necessary to engage in this reform, data-systems with accurate and timely information are necessary. This research included construction of Hierarchical Generalized Linear Models to investigate the individual- and school-level …

Investigating Students’ Basic Needs And Motivation In College Chemistry Courses With The Lens Of Self-Determination Theory, Yujuan Liu

USF Tampa Graduate Theses and Dissertations

More graduates in science, technology, engineering, and mathmetics (STEM) fields are needed to keep our nation’s preeminance in the global fields of technology and science. However, fewer than 40% of students who intend to major in STEM fields when entering college complete a STEM degree. Therefore, it is important to explore factors to improve student persistence in STEM fields at the college level as well as to understand the interrelationship between student motivation, academic achievement, and persistence. Motivation is strongly associated with student achievement and persistence; meanwhile, academic achievement can also affect persistence. Self-determination theory (SDT) represents a framework of …

Selection Of Memory Book Content: Agreement In Content As A Function Of Informant Relationship To Memory Book Recipient, Rebecca J. Allen

USF Tampa Graduate Theses and Dissertations

This study was designed to determine to what extent provision of personally relevant information and sensory cues would agree between Recipient and Informant for selection of memory book content. Six dyads married to each other an average of 29.17 years (SD = 10.03), between the ages of 43 and 70 years (Mean = 57; SD = 8.39), and cognitively competent (i.e., no diagnosis of cognitive impairment) participated. Participants completed questionnaires independently and provided personally relevant information/memories, aversions towards select memories/topics, and sensory cues on behalf of themselves (as “Recipient) and their spouse (as “Informant”). For provision of personally relevant information/memories, …

Structural Racism: Racists Without Racism In Liberal Institutions Within Colorblind States, Alexis Nicole Mootoo

USF Tampa Graduate Theses and Dissertations

Afro-Descendants suffer sustained discrimination and invisibility that is proliferated with policies that were once blatantly racist, but are now furtive. This study argues that structural racism is alive and well in liberal institutions such as publicly funded colleges and universities. Thus, structural racism is subtly replicated and reproduced within these institutions and by institutional agents who are Racist without Racism. This study builds on theories from Pierre Bourdieu, Frantz Fanon, Glen Loury and Eduardo Bonilla-Silva. The juxtaposition of their theoretical arguments provides a deeper insight into how structural racism becomes a de facto reflexive phenomenon in liberal and progressive institutions …

Computational Analysis Of Protein Intrinsic Disorder In Human Diseases, Insung Na

USF Tampa Graduate Theses and Dissertations

There are different conformational states of proteins characterized by different Gibbs free energy levels, manifested in folding-unfolding dynamics, for example. Recently, a set of protein states, which require relatively small amount of folding energies, emerged as subjects of intensive research, and proteins or regions characterized by the presence of these states have been termed as ‘Intrinsically Disordered Proteins’ (IDP) and ‘Intrinsically Disordered Protein Regions’ (IDPR), respectively. Predisposition for intrinsic disorder of a query protein is encoded in its amino acid sequence and composition, and can be rather accurately predicted using several intrinsic disorder algorithms. Since pathology of many human diseases …
