Designing A Health Coach-Augmented Mhealth System For The Secondary Prevention Of Coronary Heart Disease, Avijit Sengupta

USF Tampa Graduate Theses and Dissertations

This dissertation presents research that employs design science research (DSR) methodology to develop and evaluate a high-fidelity prototype of a home-based cardiac rehabilitation (HBCR) system to support self-management of chronic cardiovascular diseases like coronary heart disease (CHD) and to offer secondary prevention against other chronic diseases with similar risk factors. While the population of coronary heart disease (CHD) patients requiring cardiac rehabilitation (CR) continues to expand, lack of access and other barriers to center based cardiac rehabilitation (CBCR) presents a huge challenge. A mobile phone and wearable device based technological system can offer an HBCR program for CHD. By following …

Mbe Growth And Modifications Of Early Transition Metal Tellurides, Paula Mariel Coelho

USF Tampa Graduate Theses and Dissertations

Two dimensional (2D) materials present interesting property variation when compared to bulk materials as they are single layer materials with reduced dimensions effects, minimal interlayer interactions and may present changes in lattice symmetry. Van der Waals (vdW) materials are layered materials with strong in-plane covalent bonds and weak out-of-plane vdW forces, which allows crystals to be isolated down to a single molecular layer and these single layers to be classified as 2D materials. The ability of combining these materials independent of lattice matching and modifying electronic properties by using vdW heterostructures makes them promising materials for electronic devices applications. Moreover, …

The Effects Of Agrochemical Pesticide Applications On Target And Off-Target Species In Aquatic Ecosystems, Bryan K. Delius

USF Tampa Graduate Theses and Dissertations

The increase in the global human population is driving agricultural expansion, which increases the likelihood and degree by which agrochemicals impact aquatic systems. It is projected that by 2100 the global human population will exceed 11 billion, and to feed the increased human population, the necessary increase in agricultural infrastructure is estimated to double irrigation, nearly triple fertilizer applications, and increase pesticide applications by tenfold. It stands to reason that wetlands impacts from agriculture are also likely to increase as the industry expands its operation to meet the globally growing demand for food.

Wetlands are highly productive habitats that not …

A Multi-Faceted Approach To Understanding Acceptability Of Docs K-5: A Qualitative Analysis, Andrea Guarnieri

USF Tampa Graduate Theses and Dissertations

This qualitative study investigated the acceptability of DOCS K-5, a behavior parenting program adapted for parents of elementary aged children. Despite proven efficacy in preventing maladaptive behaviors, parenting programs have historically suffered from low attendance and engagement. Participants (N = 13) attending the pilot DOCS K-5 program took part in six group interviews while enrolled in the program to examine the facilitators and barriers to attendance, perceived effectiveness, and collateral benefits received from participation in the program. This study considered possible cognitive, affective, instructional, and pragmatic facilitators or barriers to attendance and engagement. Participants described motivations to learn various types …

How Culture And Storytelling Can Influence Urban Development: An Ethnographic Look At The Community-Driven Revitalization Of Newtown In Sarasota, Florida, Michala Head

USF Tampa Graduate Theses and Dissertations

When Americans think of Florida, tourist attractions often trail the initial thoughts of alligator sand chaos. Disneyworld and its neighboring parks are set up for optimal experience and consumption, the thought of a trip South along the coast for a sweltering beach day, sipping on a frozen drink in January sings to Midwesterners. For residents of these seaside cities, such as Sarasota, the experiences of the space are much more complex. Within the broader contexts of the resurgence of the Black Lives Matter movement following the murder of George Floyd and a global pandemic that impacted America’s marginalized populations disproportionally, …

Data-Driven Studies On Social Networks: Privacy And Simulation, Yasanka Sameera Horawalavithana

USF Tampa Graduate Theses and Dissertations

Social media datasets are fundamental to understanding a variety of phenomena, such as epidemics, adoption of behavior, crowd management, and political uprisings. At the same time, many such datasets capturing computer-mediated social interactions are recorded nowadays by individual researchers or by organizations. However, while the need for real social graphs and the supply of such datasets are well established, the flow of data from data owners to researchers is significantly hampered by privacy risks: even when humans’ identities are removed, or data is anonymized to some extent, studies have proven repeatedly that re-identifying anonymized user identities (i.e., de-anonymization) is doable …

Analysis And Modeling Of Strategic Interactions In Health Systems To Improve Patient Care Access, Jorge A. Acuña Melo

USF Tampa Graduate Theses and Dissertations

Affordable health care access that provides well-coordinated and high-quality services on time is a goal that governments and health organizations strive for. Regrettably, most countries deal with access problems that affect the population's health, such as long waiting lists for specialized medical services, overcrowding of emergency departments, and high health prices. In the present doctoral dissertation, I model and analyze the strategic interactions that inhabit the health system machinery to uncover possible structural problems that led to the aforementioned issues. The study involves operation research, data science, and game theory techniques to address the health care access predicament.

Each research …

An Investigation Of The Hot Docs Guide For Weekly Early Intervention Sessions: A Multiple Baseline Design, Cashea Holyfield

USF Tampa Graduate Theses and Dissertations

Many parents of young children across the United States are increasingly impacted by their children’s display of early childhood challenging behavior. Common examples of these behaviors include feeding difficulties, tantrums, whining, crying, and noncompliance (Barbarian, 2007; Hemmeter et al., 2014; Spencer & Coe, 2003). Though the relationship between early childhood behavior problems and future outcomes may not be causal, researchers have consistently concluded that if left unaddressed, children who demonstrate early challenging behavior are likely to experience some difficulties in academic achievement, sociability, school readiness, and mental health (American Academy of Pediatrics, 2002; Turney & McLanahan, 2015). Behavioral parent training …

Pre-Service Teachers' Knowledge Of The Brain: Implications For Autonomy-Supportive And Controlling Motivational Styles, Katie Jansen

USF Tampa Graduate Theses and Dissertations

Neuromyths, or misconceptions about the brain and learning that are rooted in scientific fact, have been documented among educators across various subject areas and educational levels throughout the world. The endorsement of neuromyths may affect the ability of educators to support the psychological needs of their students. The present study examined neuromyth endorsement and neuroscience literacy among pre-service educators, as well as their orientations toward autonomy-supportive or controlling motivational styles. Associations between pre- service teachers’ knowledge of the brain (i.e., neuromyth endorsement and neuroscience literacy) and their motivational styles (i.e., autonomy-supportive or controlling) were also explored. Data were gathered from …

Development Of A Numerical Process Model For Adsorbent-Amended Constructed Wetlands, Lillian Mulligan

USF Tampa Graduate Theses and Dissertations

There is a need for alternative methods for municipal landfill leachate treatment as the high concentrations of pollutants in leachate interfere with processes at publicly owned treatment works (POTWs). Constructed wetlands (CWs) have been shown to be a sustainable alternative with good removal efficiencies for chemical oxygen demand (COD) and ammonia nitrogen (NH4+). The addition of an adsorbent media, such as zeolite and biochar, to CWs to further enhance removal efficiencies has been investigated in recent years. However, the long-term effects of zeolite and biochar addition to CWs is not well known. A model could be a useful tool to …

Treatment Responses Among Youth With Anxiety Disorders And Body-Focused Repetitive Behaviors In A Clinic Sample, Katrina Scarimbolo

USF Tampa Graduate Theses and Dissertations

Anxiety disorders are considered to encompass multiple conditions, including generalized anxiety disorder, social anxiety disorder, separation anxiety disorder, panic disorder and specific phobias. Related conditions include post-traumatic stress disorder and obsessive and compulsive disorder. Body-focused repetitive behaviors (BFRBs) are a group of disorders that result in repetitive touching, picking, and/or pulling to areas of the body such as the scalp or skin (American Psychiatric Association, 2013). An anxiety disorder and a BFRB commonly co-occur in youth. This comorbid presentation produces further impairment in school attendance, peer socialization, or other functional domains. These difficulties youth experience make it pertinent to study …

Phenotypic Diversity And Costs Of Early Hatching In Lizards, Zachary Winstead

USF Tampa Graduate Theses and Dissertations

Early hatching is a form of environmentally cued hatching in which embryos can emerge early to improve chances of survival and is considered a means of antipredator defense. Early hatching as a response to predation has been well documented in amphibians, but its prevalence among other animal groups is unknown. Moreover, any trade-offs between early hatching and other traits, and thus survival, are not well understood. There is anecdotal evidence that lizards exhibit early hatching behavior, but quantitative evidence is limited to one study. In the present study, I tested for the presence of early hatching in six species of …

USF Tampa Graduate Theses and Dissertations

Post-traumatic stress disorder (PTSD) is a common and debilitating psychiatric disorder that may occur in individuals exposed to traumatic events such as accidents, interpersonal violence, war, combat-exposures or natural disasters. PTSD is a significant public health issue with a high disease burden associated with substantial health care costs and several comorbidities negatively affecting an individual’s quality of life. The biological underpinnings of the disorder are not well understood. Gene expression studies can shed light into the complex physiology of PTSD. However, to date, studies employing a hypothesis-free approach examining the whole transcriptome are scarce and are limited to assessment of …

A Review Of Marine Turtle Orientation And Artificial Lighting Impacts With Novel Results From Florida’S Gulf Coast, Andrea M. Fisher

USF Tampa Graduate Theses and Dissertations

Artificial light (i.e. unnatural light emitting from a human-made source) is one of the most extensively distributed, and least managed, type of anthropogenic pollution. Due to the disproportionally high rates of urbanization in critical coastal ecosystems, species, like marine turtles that use beach habitat for nesting activities, are especially vulnerable. Marine turtles employ the use of multiple visual cues (e.g. wavelength, intensity, background illumination, and dark silhouettes) to conduct sea-finding behavior and different variations in cue usage exist across species and geographic location. During nesting and emergence activities, orientation can be interrupted and manipulated by artificial lighting resulting in lower …

Our goal was to identify factors contributing to successful aging in this talker group. The aging population is expected to increase exponentially over the next twenty years. Factors influencing self-perceived health-related quality of life have yet to be investigated in aging AWS.

An online survey was completed by a total of 40 AWS, age 50 years and older, recruited from the Greater Tampa Bay region and nationally. The survey comprised multiple measures that probed for information regarding self-perceived health …

Flow Visualization And Aerosol Characterization Of Respiratory Jets Exhaled From A Mannequin Simulator, Sindhu Reddy Mutra

USF Tampa Graduate Theses and Dissertations

It is important to understand the airborne transmission of infectious diseases due to the COVID-19 pandemic. Physical experiments were conducted to understand the dispersion of aerosols emitted from a mannequin simulator replicating human tidal breathing through the nose and mouth with and without a protective face mask in an enclosed space. Flow patterns are observed via high-speed visualization, and the concentration and size distribution of the particles is measured as a function of distance from the mannequin using an optical particle sizer. Masks were shown to effectively reduce the horizontal dispersion of aerosol for both mouth and nose breathing. Further, …

The Extended Parallel Processing Model (Eppm) And Risk Perceptions Of Twitter Messages Related To Covid-19, Muhammad E. Rasul

USF Tampa Graduate Theses and Dissertations

Since its genesis, the novel coronavirus or COVID-19 has claimed millions of lives across the world and has infected many more. The population in the US experienced one of the worst outbreaks of COVID-19 in the world, with the number of deaths rising monolithically at one point. Although the development and inoculation of a large number of the public has helped, newer variants threaten to revitalize the growth and spread of COVID-19. Scholars have extensively studied health messages related to COVID-19 in a variety of contexts. However, little attention has been paid to the risk perceptions of health messages related …

Career Development And Workforce Experiences Of Trans People In Their Workplaces, Rene Ragmett Alvarez

Hence, I explored the career development and workforce experience stories of trans people. I used a conceptual and theoretical framework in this study to inform my general approach to trans scholarship leading to the specific examination of the career development and workforce experiences of trans persons. The conceptual and theoretical framework included Hale's (1997) suggested guidelines for non-trans people writing about trans people, constructivism, social cognitive career theory, and minority stress theory and informed the qualitative vehicle of this study to …

“Here Come The Crackers!”: An Ethnohistorical Case Study Of Local Heritage Discourses And Cultural Reproduction At A Florida Living History Museum, Blair Bordelon

USF Tampa Graduate Theses and Dissertations

This project explores the complex roles of power and heritage in the reproduction ofcultural and ethnic identities in the context of a local living history museum called Cracker Country. Throughout this thesis, I demonstrate how discourses of Florida heritage are constructed, reproduced, or contested in various ways among all the museum’s different communities of stakeholders. Using Michel-Rolph Trouillot’s (1995) theory of historical silences and expanding on Laurajane Smith’s (2006) notion of the Authorized Heritage Discourse, I explore the ways that heritage “works” at a local level, and the multitude of meanings it can hold within particular communities. I analyze the …

The Effects Of Critical Audit Matter Recurrence And Reporting Treatment On Investors’ Information Processing, Judgments, And Decisions, Hilda E. Carrillo

USF Tampa Graduate Theses and Dissertations

A new auditor reporting standard requires auditors to disclose critical audit matters (CAMs) in the auditor’s report. CAMs highlight accounts or disclosures that involved especially challenging, subjective, or complex auditor judgment. As one of few audit-related disclosures, CAMs act as an important signal of qualitative aspects of recognized (i.e., items shown on the face of the financial statements) or disclosed (i.e., items shown in the footnotes of the financial statements) financial statement items. While certain accounts or disclosures will consistently rise to the level of a CAM, other accounts or disclosures may only rise to the level of a CAM …

Cetacean Maternal Investment: Importance In Conservation Across Species And Drivers For Interspecific Altruism, Christopher Klein

USF Tampa Graduate Theses and Dissertations

Cetacean maternal investments can be useful for conservation management as well as examining behaviors such as interspecific altruism in the humpback whale, Megaptera novaeangliae. Cetaceans are among the most threatened group of marine mammals. In the second chapter, maternal investments across ~90 species/subspecies of Cetacea were analyzed to aid in the understanding of recovery/replacement for conservation and management. Using Principal Components Analysis (PCA), a relative maternal-investment index for 41 cetacean species was built. The maternal-investment index was a composite of four maternal-investment variables, the duration of gestation, lactation, calving intervals, and the number of reproduction years per female per species. …

Improving Environmental Protection: One Imagined Touch At A Time, Luke Ingalls Liska

USF Tampa Graduate Theses and Dissertations

Can imagined touch of flora and fauna (i.e., the plants and animals of the natural world) make you more willing to support environmental protection efforts? Across seven studies, I demonstrate that by asking consumers to imagine touching fauna, marketers can encourage consumers to become more engaged in environmental protection efforts. This effect occurs because imagined touch generates haptic imagery, which enhances a consumer’s emotional attachment to fauna. I demonstrate that emotional attachment to fauna induced via imagined touch enhances individual’s willingness to share Facebook posts, improves their willingness to support increased fines for environment-related offenses, and increases the number of …

USF Tampa Graduate Theses and Dissertations

The purpose of this evaluation was to investigate the factors that contribute to students’ recruitment and retention in the Arabic program at my college. The two questions guiding this evaluation were: (1) what factors influence students to join the Arabic program at my college and (2) what factors influence students to continue to enroll in subsequent higher-level Arabic courses? To accomplish this evaluation, I conducted interviews with six former students --four women and two men--in the Arabic program. Eight themes emerged following analysis of data. The findings show that students joined the Arabic program for a variety of reasons. Several …

Cytoplasmic Polyadenylation Element Binding Protein 2 Alternative Splicing Regulates Hif1Α During Chronic Hypoxia, Emily M. Mayo

USF Tampa Graduate Theses and Dissertations

Chronic pulmonary hypoxia commonly results in the sustained expression of HIF1 (hypoxia inducible factor 1), a heterodimeric transcription factor, that, if unrestrained, can result in dramatic vasculature remodeling, pulmonary arterial hypertension, and right-sided heart failure. Together, these pulmonary disorders cost approximately $100 billion annually to treat due to the limited therapeutic targets designed to inhibit HIF1 expression. In this study, we introduce a translational regulator of HIF1 expression, known as Cytosolic polyadenylation element binding proteins 2 (CPEB2). Our lab has previously demonstrated in cancer cells that alternatively spliced isoforms of CPEB2 regulate the translation of the HIF1 oxygen-dependent subunit, HIF1α, …

I conducted a qualitative study of participants in international package tourism and individual travelers, more specifically, Chinese tourists who travel to the United States. Main topics of exploration included tourists’ experience of their trips and package tours, how they interpreted American culture and compared it to their own, how they constructed and performed identities both as tourists and as Chinese nationals, their emotional experiences and how they made sense of an environment that they …

A New Age Of Telehealth: Pediatric Speech-Language Pathology Services During The Covid-19 Pandemic And Beyond, Deborah R. Campbell

USF Tampa Graduate Theses and Dissertations

The COVID-19 pandemic potentially changed the landscape of how speech-language pathologists provide services. Prior to March 2020, pediatric speech-language therapy provided via telehealth was limited; however, the COVID-19 pandemic caused a worldwide conversion from in-person care to a remote service delivery model. This conversion brought to the fore possible benefits and utility of telehealth use. Yet, clinicians potentially experienced barriers to its use, including the lack of validity and reliability evidence for remote administration of several pediatric assessments. For the viability of remotely delivered speech-language services to continue and evolve in a post-pandemic world, further research is needed to identify …
