Smoking Among Youth Living With Hiv: The Intersection Of Behavioral Health And Chronic Disease, Todd Wells

USF Tampa Graduate Theses and Dissertations

Smoking amongst youth living with HIV (YLWH) has major public health implications. When combined with the complications associated with smoking such as chronic obstructive pulmonary disorder (COPD) or heart disease, the impact of a HIV positive diagnosis increases morbidity exponentially (Nahvi & Cooperman, 2009). The purpose of this study was two-fold, to investigate the perceptions of smoking amongst YLWH aged 18-25 who received care at the CMS Clinic located at the University of South Florida and to determine factors related to cessation. A study design utilizing two components, a systematic literature review and primary qualitative data was used in this …

A Feminist Contestation Of Ableist Assumptions: Implications For Biomedical Ethics, Disability Theory, And Phenomenology, Christine Marie Wieseler

USF Tampa Graduate Theses and Dissertations

This dissertation contributes to the development of philosophy of disability by drawing on disability studies, feminist philosophy, phenomenology, and philosophy of biology in order to contest epistemic and ontological assumptions about disability within biomedical ethics as well as within philosophical work on the body, demonstrating how philosophical inquiry is radically transformed when experiences of disability are taken seriously.

In the first two chapters, I focus on epistemological and ontological concerns surrounding disability within biomedical ethics. Although disabled people and their advocates have been quite vocal regarding their views on disability and in critiquing bioethicists’ approaches to issues that affect them, …

From Tolerance To Transmission: Linking Within-Individual To Community-Level Disease Processes, Sarah Catherine Burgan

USF Tampa Graduate Theses and Dissertations

Hosts have two main strategies for coping with infections: resistance and tolerance. Resistance is aimed at preventing or eliminating parasites, whereas the goal of tolerance is to maintain performance regardless of parasite burden. The balance between resistance and tolerance within a host may mediate host competence, or the propensity of a host to infect other hosts or vectors. Hosts with high tolerance and low resistance to an infection, for instance, may be highly competent and possess the greatest potential to act as superspreaders. These superspreading hosts will contribute disproportionately to transmission, thus posing the greatest risk to other hosts within …

A Closer Look Into Remote Work: Examining Resources Within Remote Work Arrangements With Outcomes Of Job Performance And Work-Family Conflict, Kaitlin Kiburz Kiburz

USF Tampa Graduate Theses and Dissertations

Remote work has become a popular topic within organizations and the popular press. However, academic research has been inconclusive as to whether remote work is related to benefits of increased job performance and lessened work-family conflict. This study examined remote work resources to gain an in-depth understanding of how remote work relates to job performance and work-family conflict. One hundred fifty-one salespeople participated in two time-lagged surveys regarding remote work resources (autonomy, feedback, access to information and interaction with one’s supervisor), outcomes (subjective and objective job performance and work family-conflict) and demographics. Remote work resources were not significantly related to …

Blind And Visually Impaired Users Adaptation To Web Environments: A Qualitative Study, Raneem Saqr

USF Tampa Graduate Theses and Dissertations

Although much research exists on human behavior in online environments, research on users with disabilities is still rare. To draw more attention to this population, this dissertation explored browsing patterns and adaptive behaviors of people with visual disability across different online environments common in daily activities: social network, e-commerce, online information, and search engines’ websites. The main objective of this study is to propose a conceptual framework of how blind and visually impaired users browse and adapt to different web environments. We achieve this objective using a qualitative approach through three studies. In the first study, the researchers collect data …

Where Is The Survivor’S Voice? An Examination Of The Individual And Structural Challenges To The Reintegration Of Immigrant Human Trafficking Survivors, Michelle Cristina Angelo Dantas Rocha

USF Tampa Graduate Theses and Dissertations

The United States is one of the top destination countries for human trafficking, and Florida has the third highest number of reported cases of human trafficking. Despite the severity of this issue, Florida anti-trafficking legislation, reintegration programs, and awareness campaigns tend to contribute to the invisibility of the victims and undermine their recovery and reintegration into society, especially when the victims are immigrants. This project uses a multi-method approach including content analysis of anti-human trafficking campaigns to argue that portrayals of a “perfect victim” only amplify stigmatization and discrimination against immigrant victims. Through in-depth interviews and ethnographic observation highlighting the …

The Effects Of Visual Arts On Expressive Language In Participants With Dementia, Shannon Valentine Daly

USF Tampa Graduate Theses and Dissertations

Visual aids such as memory books have been shown to help increase recall of information and facilitate improved communication in people with dementia (Bourgeois, 2014). Because of the effectiveness of visual aids for people with dementia, this study aimed to determine if the type of visual stimulus would produce differences in the quality of language expressed. It was hypothesized that a more realistic picture in full color would elicit more descriptive language than a black and white line drawing. Verbal descriptions of Norman Rockwell’s realistic painting, Coming and Going and descriptions of a black and white line drawing of the …

A Cross-Methodological Investigation Of Emotional Reactivity In Major Depression, Vanessa Panaite

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is primarily characterized by prevalent sadness and anhedonia. Laboratory studies find that depression is characterized by reduced reactivity across emotional contexts, while a few studies using naturalistic designs find that depressed people show normative reactivity to negative life events and mood brightening in response to positive events. The current study was an investigation of emotional reactivity in depression through the use of experimental and naturalistic designs. This allowed for an investigation of sources of lab-life discrepancies in emotional functioning in depression, including negative affect (NA) regulation. We examined experiential reactivity across contexts and types of stimuli …

Do Early Elementary Teacher Ratings Of Classroom Behavior Predict Similar Outcomes Across Demographic Groups? An Examination Using The Early Childhood Longitudinal Study Kindergarten Cohort (Ecls-K), Amira Conservilla Mattison

USF Tampa Graduate Theses and Dissertations

Research suggests that how teachers perceive the behavior of individual children in the early years of elementary school has important implications for the school success of those youth over time (Darney et al., 2013; Hibel et al., 2010; Jimerson et al., 1997; Reinke et al., 2008). This may be because children who are of concern to teachers are often identified for practices such as grade retention and/or special education placement. Although these practices are intended to help children, they have not been shown to be associated with long-term positive outcomes. Rather, youth who are subject to these practices experience negative …

The researcher used multiple baseline design by extending with follow-up phase to determine whether students retained the knowledge they learned while engaging with the app. Even though six students participated to the study, the researcher withdrew two of them and analyzed data came from four students. The result o the study showed that all of the students …

Evaluating Prevent-Teach-Reinforce (Ptr) In A High School Setting, Kaitlin Sullivan Sullivan

USF Tampa Graduate Theses and Dissertations

Current research shows that school’s behavior intervention plans are lacking in key components, indicating a need for a standardized model of assessment that sustains teacher adherence, acceptance, and feasibility. Prevent-Teach-Reinforce (PTR) is a model that combines the principles of applied behavior analysis and positive behavior support to provide a standardized approach to conducting a functional assessment and creating a behavior plan. Studies have indicated that PTR is effective in improving student behavior and academic engagement. The current study evaluated the use of PTR for three high school students classified as emotional behavioral disorder (EBD). Results indicated that teacher-implemented functional assessment …

A Power Conflict Approach To Animal Cruelty: Examining How Economic Power Influences The Creation Of Animal Cruelty Laws, Leonard J. Genco

USF Tampa Graduate Theses and Dissertations

The current study examines the association of macro-level economic factors and the creation or enactment animal cruelty laws across the states at a fixed time. Criminologists have postulated that economic factors influence the legal system (Chambliss and Seidman, 1971). This thesis addresses whether state-level economic and related macro-level factors influences the amount and types of state animal cruelty legislation lawmakers enact. To do so, this thesis examined animal cruelty legislation and their association with measures of agricultural and farm production, Democratic Party, Republican Party, and pro-animal interest groups across all states of the United States for the time period (2012-2013). …

Cause Placement: A Conceptual Framework And Empirical Findings, Ream A. Shoreibah

USF Tampa Graduate Theses and Dissertations

The use of embedded marketing, the practice of seamlessly integrating advertising messages into entertainment vehicles, continues to grow as media consumption shifts to on-demand forms, and reaching audiences with traditional advertising becomes more challenging. This dissertation investigates cause placement, the term proposed for the social marketing equivalent of product placement, the more widely known form of embedded marketing. Cause placement is the promotion of pro-social causes by verbally and/or visually inserting related elements into entertainment programming. Cause placement merits its own stream of research, because consumers are expected to react differently to the placement of social issues than to the …

Lifted: A Thematic Analysis Of Homeless Youths’ Reflections On Their Lives Since Beginning A Multi-Faceted, Community-Based Intervention Called Starting Right, Now, Camille Ashley Randle

USF Tampa Graduate Theses and Dissertations

Although interventions that take an individualized, holistic approach to service delivery have been recommended for homeless youth, few such interventions have been described in the literature. This study sought to examine a unique, multi-faceted, community-based intervention developed in 2009 in Tampa, FL to provide services to homeless adolescents who are no longer living in the custody of a parent or guardian (i.e. unaccompanied youth). The intervention, titled Starting Right, Now (SRN), has served over 100 youth to date. The program provides residential, educational, recreational, and professional development services, as well as mental and physical health care. Each youth also receives …

Urban English Language Arts Teachers’ Stories Of Technology Use: A Narrative Inquiry, Bridget Abbas

USF Tampa Graduate Theses and Dissertations

Technology use in high-minority, low-income middle school ELA classrooms is defined by traditional instructional practices (Applebee & Langer, 2013; Attewell, 2001; Boser, 2013; Cuban, 2001; Lankshear & Knobel, 2008), barriers to access (O’Dwyer et al., 2005; Purcell et al., 2013; Warschauer & Matuchniak, 2010), and inequalities in use (Banister & Reinhart, 2011; Beers, 2004; Gorski, 2009; Makinen, 2006; Powell, 2007; Reinhart et al., 2011; Dijk, 2003, 2006; Warschauer et al., 2004). This characterization, or grand narrative, of technology use is echoed and challenged by this narrative inquiry. Here the stories of two ELA teachers frequently using technology in instruction and …

The Effects Of Racial Bias On Perceptions Of Intimate Partner Violence Scenarios, Batya Yisraela Rubenstein

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to explore how racial bias affects perceptions of intimate partner violence (IPV). Public perceptions of IPV have been studied under numerous contexts to ascertain how characteristics of victim and the offender can affect these attitudes. A portion of this body of research has been dedicated to understanding the role of race in perceptions of IPV and a large portion of the findings have been mixed due to the interaction of biases and attitudes about race and IPV. Very few studies have looked at multiple forms of IPV in comparison with one another while also …

USF Tampa Graduate Theses and Dissertations

This study examined the relationship between the level of implementation of the Multi-Tiered System of Supports (MTSS) approach to service delivery in schools and educators’ beliefs regarding MTSS, their perceptions of MTSS practices in their schools, and student growth. The study used data from the Florida Problem Solving/Response to Intervention Project. Thirty-four pilot schools in seven school districts across the state of Florida were provided intensive coaching, training, and technical assistance in implementing the MTSS service delivery model for three years. The current study focused on the final year of support. Data collected as part of the project’s program evaluation …

The Impact Of Latency Jitter On The Interpretation Of P300 In The Assessment Of Cognitive Function, Xiaoqian Yu

USF Tampa Graduate Theses and Dissertations

When stimuli processing time varies in an oddball paradigm, the latency of the P300 will vary across trials. In an oddball task requiring difficult response selections, as the variation of stimuli processing time increases, so does the variation of the P300 latency, causing latency jitters in the measurement. Averaging the P300 across different trials without adjusting this latency jitter will lead to diminished P300 amplitude, resulting in inaccurate conclusions from the data. Verleger et al. (2014) reported a diminished P300 amplitude in a difficult oddball task that required subjects to make response selections among stimuli that are difficult to distinguish, …

Attentional Window And Global/Local Processing, Steven Peter Schultz

USF Tampa Graduate Theses and Dissertations

How does the focus of attention influence the encoding of information? Research has shown that size and allocation of the attentional window has an influence on what information is attended to or missed. The size-scale of features also effects processing of visual information. Previous research involving hierarchical stimuli suggests precedence for global features. In the present experiment, I investigated the influence of attentional window size on accuracy of encoding hierarchical stimuli at the global and local level. Here I introduce a new method for manipulating the size of the attentional window and for collecting unconstrained responses. At the start of …

The Restrictive Deterrent Effect Of Warning Banners In A Compromised Computer System, Christian Jordan-Michael Howell

USF Tampa Graduate Theses and Dissertations

System trespassing, which refers to the unauthorized access of computer systems, has rapidly become a worldwide phenomenon. Despite growing concern, criminological literature has paid system trespassing little attention. The current study utilizes data gathered from a Chinese computer network to examine system trespasser behavior after exposure to one of three warning messages: an altruistic message used for moral persuasion (warning 1), a legal sanction threat (warning 2), and an ambiguous threat (warning 3). More specifically, the current study examines the temporal order of various keystroke commands to determine if some keystroke commands are used as a tactical skill to avoid …

Tactics Of Sexual Control And Negative Health Outcomes, Anna Elizabeth Kleppe

USF Tampa Graduate Theses and Dissertations

Intimate partner sexual violence (IPSV) is a concerning, yet relatively understudied form of intimate partner violence (IPV). Furthermore, the majority of research regarding sexual violence fails to differentiate between different forms of control used to facilitate this violence. Although IPV has been linked to a multitude of adverse physical and health outcomes, it is less clear how these outcomes vary by type of control experienced. Using data from the 2010 National Intimate Partner and Sexual Violence Survey (NISVS), the current study examines the physical and non-physical tactics used to facilitate sexual violence, and the associated health outcomes. Potential gender differences …

Association Of Known And Unknown Oncoviruses With External Genital Lesion (Egl) Manifestations In A Multinational Cohort Of Men, Shams Ur Rahman

USF Tampa Graduate Theses and Dissertations

Human papillomaviruses (HPV) are double-stranded, DNA, epitheliotropic viruses that infect skin and mucosal membranes. Over 200 types of HPV have been identified and classified into alpha (α), beta (β), gamma (γ), mu (µ), and nu (ν) genera. HPV in the genus α mainly infect mucosal membranes, cause the majority of the ano-genital cancers, and are widely studied. However, epidemiology of HPV in the other genera, which mainly infect skin, is poorly understood. Few studies have reported the seroprevalence of cutaneous HPV among healthy individuals, and to date, no study has prospectively examined the association between cutaneous HPV seropositivity and development …

The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes

USF Tampa Graduate Theses and Dissertations

With the growing older adult population, neurodegenerative diseases common in old age such as mild cognitive impairment (MCI) or Parkinson’s disease (PD) are becoming increasingly germane areas of research. Pharmacological treatments have thus far been unsuccessful in treating cognitive decline associated with these neurodegenerative disorders. Alternative interventions, such as cognitive training programs, have shown promise. The current dissertation contains three papers examining cognitive interventions in neurodegenerative diseases. The first paper examined the longitudinal effects of cognitive speed of processing training (SPT) among those with PD. Results showed that training gains seen at initial post-test were maintained three months later. The …

The Effect Of A Computerized Cognitive-Behavioral Stress Management Intervention On Psychological Factors And Diabetes Management, Cathy A. Bykowski

USF Tampa Graduate Theses and Dissertations

Diabetes is associated with increased psychological distress which, in turn, is associated with poorer diabetes outcomes. This study examined the impact of a nine-week Internet based cognitive-behavioral therapy intervention that targeted stress and mood in people with diabetes. It was hypothesized that the intervention would decrease psychological distress and improve diabetes outcomes and adherence to diabetes treatment regimens. Participants with type 1 and type 2 diabetes were randomly assigned to the intervention (n = 103) or a waiting-list control group (n = 74). ANCOVAs demonstrated significant group effects for the reduction of perceived generalized stress (F (1, 105) = …

Investigating Parameter Recovery And Item Information For Triplet Multidimensional Forced Choice Measure: An Application Of The Ggum-Rank Model, Philseok Lee

USF Tampa Graduate Theses and Dissertations

To control various response biases and rater errors in noncognitive assessment, multidimensional forced choice (MFC) measures have been proposed as an alternative to single-statement Likert-type scales. Historically, MFC measures have been criticized because conventional scoring methods can lead to ipsativity problems that render scores unsuitable for inter-individual comparisons. However, with the recent advent of classical test theory and item response theory scoring methods that yield normative information, MFC measures are surging in popularity and becoming important components of personnel and educational assessment systems. This dissertation presents developments concerning a GGUM-based MFC model henceforth referred to as the GGUM-RANK. Markov Chain …

How Presidents Can Become "Hip" By Using High Definition Metaphors Strategic Communication Of Leadership In A Digital Age, Mirela Camelia Stimus

USF Tampa Graduate Theses and Dissertations

The aim of this interdisciplinary research was to see whether American presidents can reach Millennials more effectively in the digital age while publicly advancing the legislative agenda of their administration. The rationale is that presidents need to gain public support to pressure Congress into passing their legislation; while doing that, they can capture the public’s interest in politics and educate civically the most inattentive audience. To accomplish the task, strategic messaging adequate to digital media is necessary. Millennials appear as having modest interest and knowledge of politics despite their intense presence on digital media. On the other hand, they represent …

A Psychometric Evaluation Of A Measure For Evaluating Youth’S And Their Parent’S Worries About Psychosocial Treatment, Robert Rein Selles

USF Tampa Graduate Theses and Dissertations

INTRODUCTION: Initial examination of treatment worries suggest they may represent an important construct; however, previously used measures were limited by their specificity, scale format, and lack of parent report. Therefore the present study sought to examine the initial outcomes and psychometrics of newly developed corresponding measures of treatment worries in youth (Treatment Worries Questionnaire – Child; TWQ-C) and their parents (Treatment Worries Questionnaire – Parent; TWQ-P).

METHODS: Participants were 94 youth (7-17-years old) and parent dyads presenting for psychosocial treatment of an anxiety disorder. Prior to initiation of treatment, dyads completed the TWQ-C and TWQ-P along with a host of …

The Role Of Threat-Based Beliefs In Mental Health Help-Seeking Processes For Depression, Jason I. Chen

USF Tampa Graduate Theses and Dissertations

Mental illness among college students is a significant public health concern. Among mental health issues, one of the most prevalent and impairing is depression. Although many students experience depression, the majority do not seek help. Past research has shown that stigma beliefs are associated with help-seeking, but interventions targeting stigma have been unsuccessful at increasing help-seeking prompting the need to explore alternative models. Currently, there has been little research evaluating the role of threat-based beliefs related to help-seeking processes. As well, it remains unclear how different threat-based beliefs may interact and be related to help-seeking intentions.

The purpose of these …
