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 …

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 …

Chorine Conversion: Biological And Water Quality Impact On Activated Carbon Block Point Of Use Filters, Horace S. Jakpa

USF Tampa Graduate Theses and Dissertations

Point-of-use (POU) activated carbon (AC) filters are ubiquitous in many U.S. households. AC can reduce concentrations of lead, other heavy metals, and mitigate taste and odor issues. However, AC filters also remove residual disinfectants, thus allowing for the proliferation of microbes in the filter. In chloraminated systems, this can lead to localized, filter-induced nitrification. Most notably, high nitrite and nitrate in drinking water can cause methemoglobinemia (blue baby syndrome) in children under the age of three, raising public health concerns.

As a control measure for nitrification within distribution systems, utilities practice periodic, short-term secondary disinfectant switches from chloramine to free …

Health Risk Assessment Of Local Populations Ingesting Water With Naturally Occurring Arsenic And Fecal Related Contaminants In Lake Atitlan, Guatemala, Marisol Alvarez

USF Tampa Graduate Theses and Dissertations

Lake Atitlan, Guatemala acts as a sink for wastewater discharge and as a source of drinking water. The populations living in the lake basin are primarily indigenous with a large percentage (70%) living in poverty. Wastewater effluent entering the lake poses an immediate health risk to those using it as a drinking-water source. Additionally, the lake is surrounded by three volcanoes and the water has concentrations of naturally occurring arsenic above the recommended reference level of 10 µg/L. Arsenic is acutely poisonous at high concentrations and has carcinogenic and neurological effects when chronically exposed at low concentrations.

The goal of …

An Examination Of Covid-19 Health Behaviors And Public Health Messaging Using The Health Belief Model And Organization-Public Relationship Quality, Aaron L. Nichols

USF Tampa Graduate Theses and Dissertations

In the context of the most severe pandemic in over 100 years, this study examined public health behavior and public health messaging using the health belief model (HBM) and organization-public relationships (OPR) as frameworks. The study employed a cross-sectional survey of students (N = 288) and employees (N = 203) at a large public university in the southeastern United States. First, the study empirically tested the components of the HBM as determinants of engaging in public health behaviors meant to slow or prevent the spread of COVID-19 and found all components of the model to be significantly related to engaging …

Data-Driven Analytical Modeling Of Multiple Myeloma Cancer, U.S. Crop Production And Monitoring Process, Lohuwa Mamudu

USF Tampa Graduate Theses and Dissertations

Globally, cancer disease is a major health issue causing a lot of deaths. The duration of time an individual diagnosed with a particular type of cancer survives has become a major area of research concern. The Kaplan Meier and Cox Proportional Hazard (Cox-PH) model have been a traditionally used method for survival analysis of cancer data. These techniques of cancer survival analysis are developed from nonparametric and semi-parametric approaches, respectively, which are not as robust as a parametric approach. In this dissertation, we proposed a new method of cancer survival analysis based on a parametric approach using multiple myeloma cancer …

Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is a neurotrophic alphavirus for which there is no effective treatment or vaccine for humans. Periodic outbreaks in the Eastern United States represent an ongoing public health problem; Florida serves as the reservoir for EEEV for the rest of the country. Reverse transcription-polymerase chain reaction (RT-PCR) is the current gold standard for molecular diagnostic testing of the presence of EEEV in vectors. However, RT-PCR is technically complex and can be difficult for mosquito control districts to utilize. In order to provide a simple, cost-effective alternative for mosquito surveillance and control, a novel one step reverse …

Serious Mental Illness In Nursing Homes: Quality Concerns, Dylan J. Jester

USF Tampa Graduate Theses and Dissertations

Objective: This dissertation is made of two academic papers followed by a chapter discussing policy implications of the findings. The objective of this dissertation is to better understand if high-serious mental illness (SMI) nursing homes (NHs) provide poorer quality of care (e.g., operationalized as staffing levels, NH Compare quality star ratings, and health deficiencies) and whether quality in high-SMI NHs is confounded by payer mix (e.g., the proportion of residents who are Medicaid-reimbursed). A modified Donabedian Structure, Process, Outcome (SPO) Model was used as the main theoretical framework.

Methods: Data came from the Certification and Survey Provider Enhanced Reports (CASPER) …

An Ecological Momentary Assessment Of Disordered Eating Behaviors Within Alcohol Use Episodes: Determining Temporal Sequencing In Food And Alcohol Disturbance, Emily M. Choquette

USF Tampa Graduate Theses and Dissertations

The co-occurrence of disordered eating and alcohol use has been well documented in the literature. Food and Alcohol Disturbance (FAD), previously referred to as “drunkorexia,” refers to the use of disordered eating behaviors within an alcohol use episode for the purpose of increasing alcohol effects and/or offsetting caloric intake from alcohol. There is a relatively limited literature base which examines FAD; however, there is evidence that FAD is associated with alcohol-related consequences and health risk behaviors. As such, further study into this phenomenon is necessary. The current study aimed to address significant limitations in the literature. While the aims of …

Social Studies Through The Visual Arts: A Case Study Of A Professional Development Program On Teachers' Curricular And Instructional Decision-Making, Cristina M. Viera

USF Tampa Graduate Theses and Dissertations

Ongoing educational reforms and the accountability movement in public education can pose significant challenges for teachers as they strive to meet a critical, social-justice vision for the social studies. Teachers’ continued professional growth and learning are viewed as the main factors towards achieving this goal; however, quite often the long-term impact of professional development goes unexplored. This qualitative case study explores the impact of an arts-based professional development program called InsideART on social studies teachers’ decisions for curriculum development and instruction. Semi-structured interviews, curricular and instructional artifacts, and researcher’s reflective journaling illuminated the impact of InsideART on social studies teacher-participants’ …

Do I Belong? What Students Teach Us About Belonging To A New University, Jennifer Ann Scaia

USF Tampa Graduate Theses and Dissertations

Foundational to this evaluation study, the participating institution aspired to improve its retention rate. Students’ perceived sense of belonging has been identified as an important variable related to student retention and persistence (Bean & Eaton, 2000; Strayhorn 2012; Strayhorn 2019; Tinto, 2017). For students to succeed beyond their first year in college, it is fundamentally important that they view themselves as valued members of the university community (Bean & Eaton, 2000; Bollen & Hoyle, 1990; Murphy, 2016).

The purpose of this study was to evaluate how undergraduate students, predicted as less likely to retain into their second year, described their …

Mealtimes In Early Childhood Education Centers During Covid-19: A Mixed-Methods Assessment Of Responsibilities, Interactions, And Best Practices, Joanna Mackie

USF Tampa Graduate Theses and Dissertations

Background: Childhood obesity is a public health problem associated with many co-morbidities. The majority of young children in the United States (U.S.) attend formal early childhood education (ECE) programs, often consuming the majority of daily calories and engaging with teachers during mealtimes. Mealtime best practices support children’s development of healthy eating habits. This dissertation aimed to understand how COVID-19 has influenced mealtimes in ECE centers, including (1) the division of responsibility between adults and children during mealtimes, (2) the child feeding dynamic, and (3) how mealtime best practices have been included during COVID-19.

Exploring Educators' Sensemaking Of Statewide Professional Learning For Educational Decision-Making Within An Mtss, Sarah E. Thoman

USF Tampa Graduate Theses and Dissertations

This qualitative inquiry explored district-based educators’ sensemaking of an ongoing, statewide professional learning series focused on special education eligibility for students with specific learning disabilities (SLD) using a response-to-intervention (RtI) approach within a multi-tiered system of supports (MTSS). Specifically, the professional learning series was designed as a community of practice (CoP; Lave & Wenger, 1991) with both face-to-face and virtual activities. The professional learning series was in its second year of implementation and educators in the first two cohorts (Cohort 1 and Cohort 2) of the series were the participants in this study. The theoretical framework of sensemaking (Weick, 1995) …

Past Ice-Ocean Interactions On The Sabrina Coast Shelf, East Antarctica: Deglacial To Recent Paleoenvironmental Insights From Marine Sediments, Kara J. Vadman

USF Tampa Graduate Theses and Dissertations

The East Antarctic Ice Sheet (EAIS) contains ~53 meters of sea level equivalent (SLE) ice, and observations suggest it is sensitive to ongoing and past climate change. The EAIS has traditionally been considered insensitive to climate perturbations because it is largely grounded above sea level. However, aerogeophysical surveys, oceanographic observations, and models indicate that large areas of the EAIS are grounded below sea level and contain 19.2 m SLE. Marine-based parts of the EAIS are thought to be located on inland-sloping beds that drain through marine terminating outlet glaciers, indicating large areas of the EAIS may be more sensitive to …

Narrative Meaning Productions Of Compassionate Healthcare: An Examination Of Cultural Codes, Organizational Practices, And Everyday Realities, Carley Geiss

USF Tampa Graduate Theses and Dissertations

This dissertation examines the social complexities of emotion in healthcare; employing a multi-level narrative approach that explores the cultural, organizational, and interactional aspects of “compassionate care.” The central question I ask is: How do cultural beliefs and values surrounding compassionate healthcare inform organizational practices and the lived experiences of individuals providing such care? This project highlights the largely overlooked cultural, structural aspects of emotion, demonstrating how pervasive collective values and beliefs become institutionalized, and how such standards inform everyday experiences of healthcare providers.

Explicating The Process Of Communicative Disenfranchisement For Women With Chronic Overlapping Pain Conditions (Copcs), Elizabeth A. Hintz

USF Tampa Graduate Theses and Dissertations

This dissertation builds upon the extant literature in fields such as medicine, psychology, sociology, women and gender studies, and communication studies to theoretically explicate and develop a measure of the process of communicative disenfranchisement (CD). This dissertation refers to CD in two capacities: (a) as the phenomenon of CD (i.e., a communication construct and process unfolding over time), and (b) as a theoretical framework (i.e., that builds on CIFC tenets and elucidates the phenomenon of CD) which is abbreviated TCD (i.e., theory of communicative disenfranchisement). TCD enables scholars to assess how talk may disempower and empower again individuals and communities …

Influencing Motivation For Alcohol Through Social Bonding, Bryan Benitez

USF Tampa Graduate Theses and Dissertations

Human survival depends upon the ability to cooperate by forming affiliative social bonds. Social bonding should therefore be a powerful motivating force in practically all human decision making. Past research demonstrates that social bonding and motivation for alcohol consumption share similar psychological and neurobiological pathways. In this study, we attempted to reduce alcohol motivation by enhancing perceptions of social bonding prior to and during the hours and days when alcohol consumption was most likely. In a predominantly female college student sample, we found mixed support for our hypotheses that a novel social bonding manipulation delivered through mobile technology would satiate …

Women Entrepreneurs In China: Dialectical Discourses, Situated Activities, And The (Re)Production Of Gender And Entrepreneurship, Zhenyu Tian

USF Tampa Graduate Theses and Dissertations

Despite the number of women entrepreneurs on the rise globally, the business world and the identity of the entrepreneur remain to be normed masculine and male gender stereotyped. This male gender stereotyping situates women who practice entrepreneurship in disadvantages, limiting their access to resources on which they depend to make meaning of their activities and identities. This imbalanced masculine gender order also manifests in China’s economy. Women entrepreneurs in China face complex contradictions and challenges when navigating an arena that privileges men and masculinity. However, not much is known about the micro-dynamics of Chinese women’s entrepreneurial experiences in light of …

Elementary Teachers' Beliefs And Practices For Building Teacher-Student Relationships In Title I Schools, Raven S. Robinson

USF Tampa Graduate Theses and Dissertations

As elementary teachers may serve as the initial advocates for students’ safety, basic needs, and emotional well-being, research has pointed to teacher-student relationships as a means of increasing successful experiences within the school setting (Baumeister & Leary, 1995; Cook et al., 2018; Pianta, 1999; Schafer & Barker, 2018). However, urban schools continue to be disproportionately identified as contexts that serve as a nexus toward lack of opportunity for student success, but a focus on teachers’ beliefs and practices for building teacher-student relationships urban, Title I schools can dispel misconceptions (Delale-O’Connor et al., 2017; Hornstra et al., 2015; Milner, 2018; Nieto, …

A Barker Type Approach For Measuring And Interpreting Vle Of Polymer Mixed Solvent Systems, Vaishali Jain

USF Tampa Graduate Theses and Dissertations

The environment around us has a great impact on human health. A polluted environment can adversely impact human health and cause diseases like cancer, skin diseases, breathing problems and many more and hence altering the quality of life. Hence it is very important to develop sensors that can efficiently detect these harmful substances from environment. Volatile organic compounds (VOCs) are carbon-based chemical substances that are volatile even at ambient temperature and pressure conditions which enter the atmosphere through industrial processes, building materials, etc.

Acoustic wave devices can detect very low concentrations (ppm, ppb) of organic compounds in the environment. A …

Why are some people better at learning new languages than others? There is a rich body of research examining this issue from multiple perspectives and at all levels of language. This study attempts to add to that knowledge at the most fundamental level of language by examining potential influences on the learning of novel phoneme contrasts. The purpose of this study was to explore whether individual differences in attentional capabilities would help adults learn a non-native phonological contrast, and whether providing explicit directions that would guide the learners’ attention could help boost their performance. VCV recordings of the Thai /p/ …

Hyperoxia-Induced Cardiac Pathophysiology In Guinea Pig Hearts, Zain Ul Abidin

USF Tampa Graduate Theses and Dissertations

Hyperoxia, is regularly introduced to critically ill patients in ICU. Nevertheless, recent studies have shown the negative effects of this treatment on patients in critical care, including increased rates of lung and cardiac injury and thereby high in-hospital mortality. Large part of the literature related to hyperoxia was majorly focused on lung injury, with no or minimal investigations on cardiac injury. Our lab is the first to investigate the effect of hyperoxia on cardiac pathophysiology in mice and showed that mice exposed to hyperoxia for 3 days demonstrated brady-arrhythmia, cardiac hypertrophy, QTc prolongation along with other electrical remodeling and functional …

Dismantling Hegemony Through Inclusive Sexual Health Education, Lauren Wright

USF Tampa Graduate Theses and Dissertations

This thesis examines the process of developing a sexual health education curriculum that is not only tailored to the unique needs of foster-engaged young women, but also those who may experience further marginalization from other mainstream programs due to their race, sexual orientation, gender identity, and/or their religious beliefs. In conjunction with the Adolescent Sexual Health Education and Research (ASHER) Program, I helped develop a sexual health education curriculum, "Choosing Myself," targeted toward foster-engaged young women and young women (ages 13-24) in the state of Florida. "Choosing Myself" is intended to be an inclusive program that empowers participants, improves their …

Identifying Skeletal Puberty Stages In A Modern Sample From The United States, Jordan T. Wright

USF Tampa Graduate Theses and Dissertations

Investigating the onset and progression of puberty can provide insight and evidence for social changes regarding the transition to adulthood. There are also many social factors that can lead to variation in the timing of the onset and progression of puberty. Methods created by Mary Lewis and Fiona Shapland for assessing changes in skeletal development associated with pubertal timing were applied to computerized tomography scans (n=400) from the New Mexico Decedent Image Database and recorded in an attempt to identify adolescent growth trends in a modern skeletal sample from the United States. This is a novel study using the methods …
