“I Wish Somebody Called Me, Told Me Not To Worry”: Evaluating A Non-Profit’S Use Of Social Support To Address Refugee Women’S Resettlement Challenges, Brandylyn L. Arredondo

USF Tampa Graduate Theses and Dissertations

This report details the qualitative findings from an evaluation of the Refugee and Migrant Women’s Initiative (RAMWI) in Tampa, FL. Founded in 2013, the 501(c)(3) provides cultural knowledge and sewing classes to resettled refugee women. Using primarily semi-structured interviews and participant observation, I place a critical lens on the non-profit to examine how refugee women and volunteers use the provided resources and experience the values (e.g., empowerment, vulnerability) RAMWI centralizes in its programs.

Interviews with refugee women, volunteers, and key informants revealed that the challenges RAMWI faces derive from six key areas of contention: 1) an informal organizational structure; 2) …

“Be Valiente”: Investigating Ethnic Identity Through Digital Storytelling With Latinx Fourth-Grade Students, Jennifer Michelle Barreto

USF Tampa Graduate Theses and Dissertations

Multilingual and multicultural students face the challenge of understanding where their ethnic identity lies in learning. The education system in the United States lacks inclusivity in classrooms, continuing monocultural views and monolinguist ideals as the norm and encouraged in curriculum and standards (Flores, 2020). This dissertation study seeks to break cultural and linguistic ideologies to better understand the development of ethnic identity in three Latinx fourth-grade students by creating a digital story. Through a sociocultural lens that includes a bioecological model (Bronfenbrenner, 1977; Vélez-Agosto et al., 2017) and multimodality (NGL, 1996) framework the study emphasizes all funds of knowledge (Moll …

Montage Music Videos: Racial Utopianism Vs. Abstract Cowboys And The Question Of Cultural Montage, Alan E. Blanchard

USF Tampa Graduate Theses and Dissertations

Along with the explosion of consumer goods in America over the past century came the human impulse to alter these objects to produce new meanings the manufacturers never intended: commercial products become amateur artists’ raw material. We see this with custom cars and the curious blending of clothes. Inevitably, digital commercial products, like music videos, would undergo a similar treatment as seen in DJ Cummerbund’s “mashup” videos “Old Staind Road” and “Blurry in the USA” where he is painting with audio tracks and sculpting with video clips to create new digital art with new meanings uncoupled from industry’s original intent …

Making A Home Away From Home: A Qualitative Study Of African Students’ Practices Of Integration In The United States, Alphonse O. Opoku

USF Tampa Graduate Theses and Dissertations

Over the last two decades, the population of international students in the world has significantly increased. More and more students from diverse backgrounds cross national borders to study. The observed increase in numbers and diversity has led to an uptick in scholarly research that focuses on the adaptation and experiences of international students. Most of these studies, particularly in the US, are informed by the acculturation theories and assimilationist frameworks of the 1900s. Also, an exclusive focus is placed on the host country, with few studies acknowledging the impact of the origin country on the international student experience. Such approaches …

Sleep Hygiene Practices And Subjective Well-Being As Predictors Of High School Students' Obtaining Sufficient Sleep During The School Week, Erin M. Brennan

USF Tampa Graduate Theses and Dissertations

Sleep is critically important to human health. However, the quantity and quality of sleep can vary within and among individuals over time, affecting overall wellness. Adolescence is a critical time for development, both for physical health, as well as health-related behaviors and habits. Physical health is known to be influenced by health-related behaviors such as sleep hygiene, which promotes good sleep. Physical health and engagement in health-related behaviors also are known to influence other aspects of well-being, namely subjective well-being, or happiness. Adolescents are often characterized by their changing sleep needs, patterns, and habits. This study is a secondary analysis …

Mitigating Negativity Bias In Media Selection, Gabrielle R. Jarmoszko

USF Tampa Graduate Theses and Dissertations

A growing body of research explores implicit negativity bias and how it influences news selection processes of media consumers. However, very little, if any, research exists exploring how negativity bias in the news selection process can be mitigated. Informed by experimental designs that have proven effective in mitigating other types of implicit bias, this study aimed to investigate whether having consumers commit themselves to definitions of their preferred type of news before engaging in the selection process alters manifestations of negativity bias in the selection. This study tested two hypotheses: H1, that non-committed individuals will have a higher selection frequency …

Feasibility Of A Virtual Group Nutrition Intervention For Adolescents With Autism Spectrum Disorder, Acadia W. Buro

USF Tampa Graduate Theses and Dissertations

Background: Youth with autism spectrum disorder (ASD) have an increased likelihood of being overweight or developing obesity. As children and adolescents with ASD exhibit problematic eating behaviors and may consume more energy-dense foods and fewer fruits and vegetables than typically developing youth, nutrition represents a modifiable obesity risk factor for adolescents with ASD, yet there is a lack of interventions to improve healthy eating and reduce the risk of obesity in this population.

Purpose: The purpose of this study was to examine the feasibility, acceptability, and preliminary efficacy of a virtual implementation of BALANCE (Bringing Adolescent Learners with Autism Nutrition …

Modeling, Control And Analysis Of Inverter-Based Generators In The Power Grids, Yangkun Xu

USF Tampa Graduate Theses and Dissertations

Nowadays, the inverter-based generators (IBGs) has been exponentially integrated into the power grid due to environment and energy saving concerns. However, the high penetration of low inertia IBGs brings new problems on the system stability. The main objectives of this dissertation are to: 1- carry out large-signal analysis to identify the stability issues and small-signal analysis to assess the stability of the power systems, and 2- provide a standard measuring procedure to identify the admittance of IBGs. In addition, investigation on a novel DC-based IBGs architecture is carried out. In this dissertation, one widely used IBG is investigated: Type-4 wind …

Data-Informed Decision Support To Improve Pediatric And Maternal Care Quality Under Medicaid Managed Care Settings, Hasan Symum

USF Tampa Graduate Theses and Dissertations

Over the last two decades, the United States has spent almost twice as much per person in healthcare compared to most other wealthy countries. However, this higher spending has not necessarily transformed into improved quality of care; According to World Health Organization reports, the US now ranks 39th for child health and wellbeing and worst in maternal care among developed nations. In terms of proportion of preventable hospital visits, low-risk cesarean sections, and avoidable maternal morbidity/death, the U.S. is among the highest compared with the peer nations. The prevalence of these adverse outcomes in pediatric and obstetric care is particularly …

Rethinking Settlement Patterns At The Weeden Island Site (8pi1) On Florida’S Central Gulf Coast, Heather E. Draskovich

USF Tampa Graduate Theses and Dissertations

The Weeden Island site (8PI1), despite its importance as a Weeden Island period (AD 200-900) settlement and ceremonial center of the southeastern United States and type site for the ceramic series bearing its name, has largely remained poorly-dated given its size and multiple components. With the limited number of dates available to archaeologists from the Weeden Island component, there has continued to be a lack of temporal and spatial control needed to answer many of the significant questions involving change at the site. Through the execution of shovel testing in previously uninvestigated areas of the site and analysis of material …

Green Business And The Culture Of Capitalism: Constructing Narratives Of Environmentalism, Julia S. Jester

USF Tampa Graduate Theses and Dissertations

There are widespread colloquial arguments claiming that any actions taken to combat climate change will be bad for business and the economy, scaring people into continuing their support for the status quo for fear of their financial security. Alternatively, those attempting to combat ecological destruction have subsequently made transitions to sustainable development of products and shifting consumer behavior within this system. There is one core argument that both sides have, albeit in different ways – capitalism and environmentalism are seemingly incompatible; one cannot be successful without the eradication of the other. While it may appear there are only strict binary …

Field And Remote Sensing Analysis Of The 2015 Pyroclastic Density Currents At Colima (Mexico) And Calbuco (Chile) Volcanoes: Implications For Hazard Assessment And Crisis Management, Elodie Macorps

USF Tampa Graduate Theses and Dissertations

Although one of the most spectacular phenomena of active volcanoes, Pyroclastic density currents, or PDCs, are considered the most dangerous volcanic hazards. PDCs are avalanches of hot volcanic gases, ash, and larger volcanic fragments that travel at incredible speed down the flank of a volcano. High dynamic pressures, high temperatures, and high velocities are the primary dangers associated with PDCs and lead to near-complete destruction and death.

I use a multi-disciplinary approach to study the deposits left behind by PDCs, in order to understand their dynamics, their interactions with the receiving landscape, and their final distribution, starting on the ground …

Bayesian Multivariate Joint Modeling For Skewed-Longitudinal And Time-To-Event Data, Lan Xu

USF Tampa Graduate Theses and Dissertations

In epidemiologic and clinical studies, a relatively large number of biomarkers are repeatedly measured in patients over time, often associated with data on epidemiologic and clinical interest events. So, much attention is focused on developing the specific patterns of the longitudinal measurements, and the associations between those patterns and the time to a certain event, such as heart attack, diagnose of disease, time to transplantation, or death. In the last two decades, the research into joint modeling of longitudinal and time-to-event data has received a tremendous amount of attention.

Numerous researchers have proposed joint modeling approaches for a single longitudinal …

Reference-Dependent Choice On Digital Platforms, Joshua K. Kaisen

USF Tampa Graduate Theses and Dissertations

Throughout this dissertation I explore a significant departure from the standard model of rationality known as reference-dependence. The theory reference-dependence asserts that an individual’s choice is dependent on their frame of reference established through factors divorced from their rational cost and benefit. This behavior is inefficient as individuals fail to rationally optimize their payoffs. This behavior is understudied in natural settings where isolating specific stimuli which may establish a reference is challenging. However, digital platforms contain limited stimuli which are fully observable to researchers and present an ideal setting to study the theory of reference-dependence. Thus, I introduce three new …

Site Suitability Modeling In The Sand Pine Scrub Of The Ocala National Forest, Jelane M. Wallace

USF Tampa Graduate Theses and Dissertations

Central Florida’s Ocala National Forest is the largest remnant of the unique-to-the-region Sand Pine Scrub ecosystem. This ecosystem exhibits a surprising wealth of biodiversity despite what may be characterized as barren, difficult, dry, pyrogenic conditions. Significant prehistoric sites exist throughout the forest, even in the Sand Pine Scrub; however, most are on the margins and few systematic surveys penetrated this ecosystem, until now. I utilized GIS and these recently collected archaeological survey data, in conjunction with other environmental, geological, or historical data in GIS format, to model prehistoric settlement and land use patterns. This model attempts to address questions of …

Leaf Cutter Ant Nest Soil Cement Stabilized Earthen Bricks: Materials And Methods For Engineering Field Applications, Faith Malay

USF Tampa Graduate Theses and Dissertations

As climate change threatens vulnerable tropical climates and development outpaces resource availability, the need for diverse construction material grows. The United Nations Sustainable Development Goals aim to reduce poverty in all forms. Diversifying construction material works toward reducing indoor air pollution, the eradication of houselessness, encouraging diversification in industry, and supporting small scale industrialization. In the Province of Bocas del Toro in Panama, there is a tenuous connection to the greater industries in the country due to location and existing infrastructure.This research presents a literature review of the historical approaches to the construction and chemistry of cement stabilized earth bricks, …

Saudi Teachers’ Perspectives On Implementing Evidence-Based Practices Specifically Designed For Students With Autism Spectrum Disorder, Ahmad Saad Alghamdi

USF Tampa Graduate Theses and Dissertations

The concept of evidence-based practices (EBP) for students with autism refers to a set of practices that were established based on research evidence that proved their effectiveness in helping improve functional and academic skills for children who have autism (Wong et al., 2015). Vision 2030 is an ambitious plan by the Ministry of Education in the Kingdom of Saudi Arabia (KSA). The ministry has published a new executive framework for the reform of teacher preparation programs (Planning and Development Agency, 2018). This reform is aimed at improving the quality of special educators, through the modernization of teacher preparation programs by …

Adaptive Network Slicing In Fog Ran For Iot With Heterogeneous Latency And Computing Requirements: A Deep Reinforcement Learning Approach, Almuthanna Nassar

USF Tampa Graduate Theses and Dissertations

In view of the recent advances in Internet of Things (IoT) devices and the emerging new breed of smart city applications and intelligent vehicular systems driven by artificial intelligence, fog radio access network (F-RAN) has been recently introduced for the next generation wireless communications. The capability of F-RAN has emerged to overcome the latency limitations of cloud-RAN (C-RAN) and assure the quality-of-service (QoS) requirements of the ultra-reliable-low-latency-communication (URLLC) for IoT applications. To this end, fog nodes (FNs) are equipped with computing, signal processing and storage capabilities to extend the inherent operations and services of the cloud to the edge. However, …

Optimization And Machine Learning Methods For Solving Combinatorial Problems In Urban Transportation, Aigerim Bogyrbayeva

USF Tampa Graduate Theses and Dissertations

This dissertation investigates three applications of emerging technologies for urban trans- portation. In the first chapter, we design a new market for fractional ownership of au- tonomous vehicles (AVs), in which an AV is co-leased by a group of individuals. We present a practical iterative auction based on the combinatorial clock auction to match the interested customers together and determine their payments. In designing such an auction, we con- sider continuous-time items (time slots) which are defined by bidders, and naturally exploit driverless mobility of AVs to form co-leasing groups. To relieve the computational burdens of both bidders and the …

Racial Threat Theory: A Test Of The Economic Threat Hypothesis, Carl L. Reeds

USF Tampa Graduate Theses and Dissertations

Racial disparities in the criminal justice system are well documented. While one potential contributor to these disparities may be differential offending on the part of racial groups, another alternative or additional explanation is racial discrimination. Blalock developed racial threat theory to explain macro-level discrimination. According to this theory various forms of “threat” posed by minority populations to majority populations leads to more formal social control or disparate formal social control, such as the formal social control that is imposed by the criminal justice system. According to Blalock, “economic threat” occurs when the Black population has large or increasing economic resources …

Archaeology And Seasonality Of Stock Island (8mo2), A Glades-Tradition Village On Key West, Ryan M. Harke

USF Tampa Graduate Theses and Dissertations

Later Glades-period cultures (ca. 500–1760 CE) of south Florida and the Florida Keys are understudied and thus poorly understood, especially those that pre-date the arrival of Spaniards to the New World. Recent archaeological models of their sociopolitical organization suggest that by the Glades I-II transition (750/800 CE), south Florida peoples were organized into what appear to be regional population centers (e.g., Pineland and Mound Key, Granada, Turner River) and smaller hinterland towns in the Everglades (e.g., Cane Patch, Bear Lake) and the Florida Keys (e.g., Stock Island, Clupper Site). Smaller towns are hypothesized to be sedentary, heterarchically-organized, simple chiefdoms from …

Blaine Amendments And The Judiciary: An Analysis Of Government Aid To Religious Schools, Dustin A. Robinson

USF Tampa Graduate Theses and Dissertations

First introduced in 1875, Blaine Amendments restrict private, parochial schools from utilizing publicly acquired funds. While the federally proposed Blaine Amendment died on the Senate floor, 37 states have adopted constitutional language that limits and/or bars religious schools from receiving public funds. Fraught with bigotry and labeled as discriminatory, such measures have not gone without challenge and the judicial system has delivered numerous decisions on funding public and private schools. However, jurisprudence reveals significant shifts in court decisions over time. Through analysis of Supreme Court cases from Everson v. Board of Education (1947) to Espinoza v. Montana (2020), this work …

The Ring Of Gyges 2.0: How Anonymity Providing Behaviors Affect Willingness To Participate In Online Deviance, Cassandra E. Dodge

USF Tampa Graduate Theses and Dissertations

Anonymity has long been discussed as a source of disinhibition. The myth of the Ring of Gyges illustrates how a person may act immorally solely because they know they will not be caught (Plato, 375/2017). Incorporating perspectives of rational choice and deterrence, anonymity serves as a form of risk reduction within hedonistic calculus (Beccaria, 1764/1963; Bentham, 1781/2000). Analogous to the myth of the Ring of Gyges (Plato, 375/2017), techniques of anonymity “hide” users from others while online. These techniques serve as a form of risk reduction, reducing the certainty of punishment (Becarria 1764/1963). Additionally, there are many ways by which …

Affectivetda: Using Topological Data Analysis To Improve Analysis And Explainability In Affective Computing, Hamza Elhamdadi

USF Tampa Graduate Theses and Dissertations

We present an approach utilizing Topological Data Analysis to study the structure of face poses used in affective computing, i.e., the process of recognizing human emotion. The approach uses conditional comparison of different emotions, both respective and irrespective of time, with multiple topological distance metrics, dimension reduction techniques, and face subsections (e.g., eyes, nose, mouth, etc.). The results confirm that our topology-based approach captures known patterns, distinctions between emotions, and distinctions between individuals, which is an important step towards more robust and explainable emotion recognition by machines.

Evacuation Decision Making And The Role Of Social Connections Across Evacuation Statuses During Hurricane Irma, Nathan D. Shull

USF Tampa Graduate Theses and Dissertations

The purpose of this research was to examine the evacuation decision-making process during Hurricane Irma in 2017. Special consideration was given to the role of an individual’s social connections (SCs). Additionally, the dependability, density (i.e., social network size and number of connections), and diversity of SCs were compared between those who: (a) evacuated to a shelter in Pinellas County, (b) evacuated to somewhere outside of the Tampa Bay area, and (c) did not evacuate. Data for evacuees and non-evacuees from Collins et al. (2018) were used to perform this comparison, while the data for shelter evacuees were acquired via a …

A Self-Study Of Need-Supportive Teaching In Elementary Art, Craig Jacobowitz

USF Tampa Graduate Theses and Dissertations

I present a self-study of my need-supportive teaching practice. I have long been curious about what it is about my teaching, what I say and do, that motivates students to work harder on their artwork and persevere when they become mired in difficulties. Need-supportive teaching addresses students' basic psychological needs within the classroom setting through high-quality teacher/student relationships and structure. Need-supportive teaching, motivation, and academic resilience are areas I made an extensive study of, as presented in chapter two. In March of 2020, the educational landscape in the United States was altered by the arrival of the unprecedented and novel …

Factors Controlling Circulation At The Terminus Of A Shallow Seagrass-Dominated Estuary, Fort Desoto Bay, West-Central Florida, Charles Gray Vickery

USF Tampa Graduate Theses and Dissertations

Fort DeSoto Bay is a shallow seagrass-dominated estuary located landward of Mullet Key that is home to the most extensive seagrass beds in all of Tampa Bay. During a period of development in the 1950s and early 1960s, the bay underwent extensive physical modifications, including the construction of earthen causeways and dredged channels, which altered the bathymetry of the seafloor and changed natural circulation patterns. The stagnation of water in the southern bay and increased estuarine residence time led to elevated summer temperatures, reduced dissolved oxygen levels, and die-offs of seagrasses. Two 40-foot circulation bridges were installed on each causeway …

Mental Health Problems, Traumatic Brain Injury, And Offending Behavior Among Persons Incarcerated In A County Jail, Lauren F. Fournier

USF Tampa Graduate Theses and Dissertations

Previous work has found that although mental illness is positively related to offending behavior, it is a fairly poor predictor of aggression, violence, offending, and recidivism after controlling for sociodemographic and historical risk factors (i.e., criminal history, age, race, gender). This refutes the model that mental illness is a direct cause of crime. Instead, risk for recidivism or crime related to mental health problems may be higher when combined with other risk factors. The current study evaluated traumatic brain injury (TBI) and associated symptoms of post-concussion syndrome (PCS) as potential moderators of the relationship between mental health problems and concurrently …

Morality And Offender Decision-Making: Testing The Empirical Relationship And Examining Methodological Implications, Jacquelyn Burckley

USF Tampa Graduate Theses and Dissertations

Rational Choice (RC) theory has become one of the most influential theories in criminology and social science with a wide body of empirical support indicating that offending is associated with anticipated costs and benefits. Although RC theory has been widely researched and supported, one area that is largely underemphasized in this theory’s discourse is morality. The present study draws on a sample of undergraduate students from a large southeastern university using a drinking and driving scenario to extend the RC literature theoretically and methodologically.

The theoretical results indicate that, consistent with prior literature, morality, certainty, and severity were directly, inversely …

The Feasibility Of 18f-Fdg Labeled Rbc And Pet/Ct Imaging Blood Perfusion And Vascular Dysfunction Measurements In Pre-Clinical Research, Shaowei Wang

USF Tampa Graduate Theses and Dissertations

Heart disease, dementia, and stroke are significant public health issues and leading causes of mortality and morbidity worldwide. Abnormalities in blood perfusion and vascular structures are seen in varieties of pathologies, including cerebrovascular diseases like stroke and dementia, hypertension, cardiovascular disease like atherosclerosis, diabetes, peripheral artery disease, and vasculitis, and tumor angiogenesis. Imaging perfusion/vascular abnormalities in these patients often plays a vital role in clinical diagnosis and treatment decisions.

Vascular diseases typically present as macrovascular or microvascular diseases. Microvascular disease (MVD) refers to vascular disease primarily affecting the arterioles, venules, and capillaries in various organs. Furthermore, MVD is widely found …
