Introducing A Mobile Health Care Platform In An Underserved Rural Population: Reducing Assimilations Gaps On Adoption And Use Via Nudges, Joseph Hodges

USF Tampa Graduate Theses and Dissertations

Rural communities are often overlooked when it comes to offering cutting edge consumer healthcare technologies. Mobile applications usually exclude populations in rural demographics due to the infrastructure requirements and available technology in the region. The population studied is a low income rural health plan in southwest Georgia. They are uniquely considered as they have the highest healthcare costs in the U.S. and are compared to healthcare costs among higher income populations like Vail, Colorado. Innovations, such as mobile healthcare applications, have the capacity to offset some of these costs, but even if adoption occurs, this does not guarantee use will …

The Progressive Transformation Of Medellín- Colombia: A Successful Case Of Women's Political Agency, María Auxiliadora González-Malabet

USF Tampa Graduate Theses and Dissertations

Medellín, Colombia, once one of the most corrupt and violent cities in the world, is now one of the most progressive and democratic cities in South America. This transformation was due to the mobilization of women’s movements and the influx of women in the city’s executive branch. Female political agency and new urban development programs reshaped democratic practices for the citizenry. This research examines the robust association between women’s organizations, women from Compromiso Ciudanano (CC), and a solid and active civil society. The theoretical framework covers democratization, good governance, and Latin American/Indigenous Feminism. The sources include interviews, polls, news articles, …

Disciplinary D/Discourses: Navigating And Negotiating Disciplinary Paradigms, Michael R. P. Bailey

USF Tampa Graduate Theses and Dissertations

Over the past twenty-five years, in the United States, zero-tolerance policies that were initially implemented to deter gun violence and drugs in schools have expanded to include a wide range of discretionary offenses such as disrespect and defiance. As a result, many students have been denied access to educational opportunities, been excluded from their peers, and had their lives irrevocably changed due to systemic sanctioning of exclusionary practices. Educators, who are caught between competing societal demands, job expectations, and ethical beliefs about their profession are tasked with balancing the instructional and interactional components of their work in an attempt to …

Promoting Healthy Sleep Practices Among Parents Of Young Children: A Preliminary Randomized Controlled Trial, Kristin Lynn Edwards

USF Tampa Graduate Theses and Dissertations

One of the most significant and underrecognized public health concerns in young children is related to the consequences of inadequate sleep. Inadequate sleep may result in problems related to behavioral regulation, executive functioning, and academic performance. ‘Sleep hygiene’, a term that describes consistent daytime and nighttime practices that promote healthy sleep, has been found to significantly increase sleep duration and improve sleep quality in the pediatric population. Researchers have found that many parents have a poor understanding of sleep hygiene. The purpose of this study was to determine if an educational intervention increased parental knowledge and practices of sleep hygiene …

Past Climate And Sea-Level Reconstruction Using Cave Deposits From Mallorca, Spain, Oana-Alexandra Dumitru

USF Tampa Graduate Theses and Dissertations

The potential impacts of the increasing temperature on the water resources, as well as the hazards associated with the sea-level rise in the low-elevation coastal zones of the Mediterranean Sea, makes this region vulnerable to current climate change due to global warming. Hence, accurate projections of the future hydroclimate scenarios in this area are crucial. Long-term information on climate and sea-level variability cannot be obtained by direct observations or using short instrumental records. However, various geological archives may provide valuable data that can be then used to assess the models used for future predictions.

This thesis presents results on past …

Book-Sharing As A Context For Fathers And Mothers To Enhance Language Development Of Their Preschool Children, Yagmur Seven

USF Tampa Graduate Theses and Dissertations

Poor reading levels is a pervasive problem in the US. For example, two of every three eigth grade students in the US are estimated to demonstrate insufficient reading comprehension skills. Early use of decontextualized language, in which the language expressed is removed from the here and now, serves as a precursor of academic language proficiency. Starting as early as the third year of life, decontextualized language is less likely to be practiced in lower socio-economic status (SES) households. Although storybooks offer a rich context for practicing the language with young children, reading storybooks alone is not adequate to promote conversational …

Life After Graduation: Current Seniors' Perceptions Of Alumni Engagement And Their Expectations Of The Institution Once They Graduate, Jessica Burns Fugate

USF Tampa Graduate Theses and Dissertations

Alumni participation in the life of an institution is more important now than ever before as state and federal funding continue to shrink and alumni are called on for financial support and to serve as resources for current students. Institutional leaders are hard-pressed to bring in external revenue to bridge the gap as budgets shrink to successfully balance operational costs (Barr & McClellan, 2011), which is done mostly through fundraising efforts targeted toward parents of students, alumni and often current students before they graduate to establish a culture of philanthropy. This need for external revenue increases the necessity for engaged …

Highway Lane Management Policy For Existing And Connected Autonomous Vehicles, Md Mokaddesul Hoque

USF Tampa Graduate Theses and Dissertations

Trucks carry major bulk of freight in the U.S. and are likely to continue doing so in the near future for various reasons. They have tremendous impact on highway pavement design and on the costs of pavement construction, maintenance, and rehabilitation. Current policy of truck lane restriction ensures that they mostly use the outside lane(s) on multilane highways. This practice has considerable impact on the cost of pavement construction and rehabilitation. Right now, all the highway lanes are designed and constructed according to the truck load on the outside lane even though the inside lanes receive significantly smaller quantity of …

Reducing Underrepresentation: Promising Practices In Florida, Catherine A. Mullins

USF Tampa Graduate Theses and Dissertations

In this study, I examined representation rates of gifted students from diverse backgrounds in Florida county school districts. Florida state legislation governing gifted student education allows for alternative identification methods to be used for students from underrepresented groups if plans for such identification are approved by the Florida Department of Education; however, this option, informally referred to as “Plan B” after subsection B of the legislation governing gifted services, is not a requirement that districts must follow. Consequently, there are large differences in the ways districts identify underrepresented students for gifted services. State legislation identifies underrepresented populations as students with …

Investigating Among-Individual Growth Heterogeneity In Longleaf Pine: Advancing Dendrochronological Approaches, Jamie E. Munn

USF Tampa Graduate Theses and Dissertations

Within a population, individuals frequently differ in the rate at which they grow, and this rate can be impacted by both genetic differences and abiotic factors. Often, dendrochronology is used to elucidate growth trends based on climate or other factors. This dissertation explores new statistical approaches to dendrochronological research.

First, I created a chronology for a population of longleaf pine (Pinus palustris P. Mill.) individuals in a southwest Florida sandhill community. I then used generalized linear mixed models to investigate the effects of fire frequency, year, tree age and size, and elevation on variation in radial growth heterogeneity. I then …

HIV continues to disproportionally affect marginalized populations, and vast amounts of money, time, and effort have been spent to understand how to slow the rate of new infections and improve health outcomes for People Living with HIV (PLWH). This study aims to understand the experience of living with and managing HIV while on …

Using Critical Race Theory To Examine Race And Racism In Social Work Education, Ebony Nicole Perez

USF Tampa Graduate Theses and Dissertations

Race and racism have proven to be a core concept of U.S. society that impacts People of Color through a set of challenges which have created and maintained enduring racial disparities and inequities. The social work profession has a time-honored commitment to working with and advocating historically marginalized populations. Social workers work with individuals, groups, and communities to help assess needs, strengths, support networks, respond to crisis situations, and advocate for social justice. The purpose of this qualitative case study was to investigate the experiences of undergraduate social work educators (BSWEs) who teach to encourage the development of students’ knowledge, …

The Chemical Ecology And Drug Discovery Potential Of The Antarctic Red Alga Plocamium Cartilagineum And The Antarctic Sponge Dendrilla Membranosa, Andrew Jason Shilling

USF Tampa Graduate Theses and Dissertations

Chemical ecology is the study of chemical interactions between organisms and their environment mediated by small molecules involved in nonessential physiological functions, known as secondary metabolites. These compounds can be crucial to survival of the organism, and have also provided the field of medicine with some of history’s most influential drugs, referred to in that context as natural products. Antarctica is a dynamic and understudied environment, which affords the opportunity to examine the chemical ecology of unique organisms while simultaneously evaluating their novel chemistry for potential therapeutic properties as natural products.

Plocamium cartilagineum is a red macroalgal species found in …

“We Can Learn Some Things From Them, But They Can Learn Some Things From Us Too”: Intergenerational Perceptions Of Shared Infant Feeding Information, Alexis L. Woods Barr

USF Tampa Graduate Theses and Dissertations

Breastfeeding is associated with unparalleled benefits for infants, mothers, families and society. In light of the breastfeeding disparities and health disparities experienced by the African American community, their women and children stand to gain the most from breastfeeding practices compared to other first-food feeding methods. Moreover, African American mothers are constantly exposed to messages, images, and stereotypes about motherhood (from multiple channels of communication) which influences their infant feeding practices. Many of these exposures send mixed messages and tend to be cultural contradictions of Black motherhood. What complicates this issue is the shortage of research that investigates the intergenerational infant …

“Man Plans But Ultimately, God Decides”: A Phenomenological Investigation Of The Contextual Family Planning Beliefs Of Recently Resettled Congolese Refugee Women In West Central Florida., Linda Bomboka Wilson

USF Tampa Graduate Theses and Dissertations

Existent demographic changes in the United States are largely a result of the current international refugee crisis. Within the past three years, there has been an influx of refugees who were affected by the wars in the Democratic Republic of Congo (DRC). Congolese refugees were the highest number of all refugee groups to arrive in the United States in Fiscal Years 2016-2018, yet little is known about their lived experiences, particularly as they apply to reproductive health and family planning in general. Congolese refugee women who resettle in the United States are unique because many lived in refugee camps for …

Millimeter-Wavelength Characterization Of The Co Emission Of Comets 174p/Echeclus, 29p/Schwassmann-Wachmann, And C/2016 R2 (Panstarrs), Kacper Wierzchos

USF Tampa Graduate Theses and Dissertations

Comets are fascinating minor solar system bodies. They contain some of the most pristine and unprocessed material found in the solar system. As a comet approaches the Sun it displays the characteristic cometary coma and tail. This is due to the release of volatile species through a variety of processes. In the present work I studied the carbon monoxide emission of three very unique comets; 174P/Echeclus, 29P/Schwassmann-Wachmann and C/2016 R2 (PanSTARRS) with different radio telescopes at millimeter wavelengths. After molecular hydrogen, carbon monoxide is the second most abundant molecule in the universe, and is also the most volatile of the …

(Re)Making Worlds Together: Rooster Teeth, Community, And Sites Of Engagement, Andrea M. M. Fortin

USF Tampa Graduate Theses and Dissertations

My research examines the communicative practices by which fans of the entertainment brand Rooster Teeth (RT)—with millions of members around the world engaged with one another through in-person meetups, as well as a variety of digital spaces — constitute community. I study these moments in communication in terms of sites of engagement, or real-time windows where actions occur through the intersection of people, mediational means, and social practices. My research is important for a contemporary understanding of communities, as well as being critical in considering how our online and offline practices are inextricably tied in ways we have only begun …

Taking An “Ecological Turn” In The Evaluation Of Rhetorical Interventions, Peter Cannon

USF Tampa Graduate Theses and Dissertations

This dissertation seeks to develop a new method for the evaluation and assessment of therapeutic libraries in a health ecology. To do so, I employ a modified version of Lloyd Bitzer’s rhetorical situation as a methodological tool for the investigation of health ecologies by applying an ecological analysis to an alcohol and other drug (AOD) treatment center in Tampa, Florida. By modifying Bitzer’s rhetorical situation schema and expanding the concept of health ecologies, I develop several innovations useful for tracing the impact of actants and rhetorical events specific to health and medicine. A major focus of this dissertation is a …

Perceptions Of The Effectiveness Of Food Policy Coalitions In Strengthening Community Food Security In The United States., Joseph G. England Iii

USF Tampa Graduate Theses and Dissertations

Food insecurity is experienced most acutely and addressed most innovatively at the community level to which the concept of community food security (CFS) finds purchase (Hamm and Bellows, 2003). In recognition of the many varying dynamics embedded in the CFS concept, Food Policy Coalitions have become an organizational model adapted by communities across the United States. While FPCs have grown in number considerably over the last decade, there remains a considerable lack of empirical research documenting evaluation and engagement methods, as well as strategies used to address community food security. This research, framed by the Community Coalition Action Theory, draws …

The Experiences Of African American Male Computer Science Majors In Two Year Colleges, Simone Brookins Jenkins

USF Tampa Graduate Theses and Dissertations

As the field of computer science grows and the computing science workforce demands more qualified workers, the United States workforce will require underrepresented minorities to help meet these demands. African American males are a demographic that can help meet this need but there are few of them pursuing computer science careers and successfully graduating with computer science degrees. The purpose of this qualitative study was to examine the experiences of African American male two-year college students who are in pursuit of a degree in computer science. My findings indicated that the study participants’ experiences such as positive interactions with faculty …

Building A Collaborative Culture In A Middle School: A Case Study, Andrew Olson

USF Tampa Graduate Theses and Dissertations

There is extensive research indicating the importance of teachers working together in teams and in conjunction with school leadership to improve teaching practice and, ultimately, outcomes for students. However, there is little evidence that collaboration is valued in the American school system. Tension pervades in a system that often prescribes a top-down approach to teacher evaluation, fails to provide sufficient time for teachers to collaborate, and unfairly scapegoats teachers for many challenges both within society and the education system itself. It is not surprising that teachers are leaving the profession at an alarming rate.

Combine these contextual factors with the …

Methods: This study used a transformative mixed methods design to understand young Black women’s most recent family planning care experience in the last 12 months through Intersectionality, Psychological Reactance, …

Epidemiological Analysis Of Malaria Decrease In El Salvador From 1955 Until 2017, Tatiana I. Gardellini Guevara

USF Tampa Graduate Theses and Dissertations

The disease of malaria is complex, with clinical presentation that ranges from severe and complicated to mild and uncomplicated or even to asymptomatic malaria. A recent effort made by several world organizations has shown important advances in the effort to control and eradicate malaria. Following the general ordinance established by the trans-border organizations, each country has tried to define, according to their local geopolitical scenario, individual ¨road maps¨ to succeed in reducing the morbidity and mortality caused by malaria. Moreover, it is now accepted universally that these road maps need to be revised and appropriated in order to correct actions …

Developing A Computer-Managed Mentor Matching System For Graduate Students, Donna J. Knudsen

USF Tampa Graduate Theses and Dissertations

Changes to the higher education landscape resulting from digital-age advancements in technology limit the opportunities for doctoral students and faculty to find one another for research and mentorship pairings as they once did when higher education was a wholly brick and mortar enterprise. Further, doctoral student attrition has remained unmoved at approximately 50% since the 1990s, with studies consistently citing the absence of mentoring (or doctoral students’ dissatisfaction with their mentors) as chief among the factors that contribute to the high rate of attrition. Some predict that the rate of doctoral attrition is as much as 20% higher for programs …

Multimodal Treatment And Neoadjuvant Chemotherapy Trends, Utilization And Survival Effects In Intrahepatic Cholangiocarcinoma – A Propensity Score Analysis, Ovie Utuama

USF Tampa Graduate Theses and Dissertations

Intrahepatic Cholangiocarcinomas (ICC) are fatal malignancies common among the elderly. Patients are diagnosed late and often relapse, even after curative-intent surgery (CIS). In this context, additional systemic chemotherapy (multimodal treatment) is recommended for most patients but reported survival benefits are minimal and are limited to small single institutional studies. For this reason, using a national cancer registry, we sought to characterize multimodal treatment trends and utilization in general and neoadjuvant chemotherapy, specifically, as well as evaluate their survival effects among the larger population. We hypothesized that, 1). Elderly ICC patients would have survival benefits equivalent to younger patients, 2). Neoadjuvant …

Phasor Measurement Unit Data-Based Steady State And Dynamic Model Estimation, Anas Almunif

USF Tampa Graduate Theses and Dissertations

Phasor measurement units (PMUs) have been put into power grid for real-time monitoring. This research investigates the PMU data for steady state estimation and dynamic model estimation. It focuses on three main research areas to enhance the security of the power system monitoring. First, optimal PMU placement (OPP) problem is developed to minimize the number of PMUs required for the system to be completely observable using mixed integer linear programming and nonlinear programming. Second, PMU measurements are ranked for oscillation monitoring based on two approaches: oscillation mode observability and Prony analysis. Further, the principles, multi-channel data handling, and noise resilience …

Evaluating Conversation Agent Impact On Student Experience In A Distance Education Course, Grover Walters

USF Tampa Graduate Theses and Dissertations

We explore the efficacy of conversation agents operating as an instructional aid in a distance education course. Two aspects of efficacy are considered—conversation agent impact on student perceptions of the experience, and how different design features of the agent affect student perceptions of engagement. Evaluation of the agent is accomplished by collecting data from 24 undergraduate participants separated into random groups. We conduct two rounds of mixedmethod evaluation. Between the two rounds, a modification to the agent occurs based on the outcome of the first evaluation. Findings include limitations related to phrasing and data persistence features of the design that …
