Promoting Subjective Well-Being In Middle School: Role Of Internalizing And Externalizing Behaviors In A Targeted Positive Psychology Intervention, Letty Langton Dileo

USF Tampa Graduate Theses and Dissertations

In a dual-factor model, complete mental health entails average-to-high subjective well-being (SWB, happiness) and few internalizing and externalizing behaviors (IEB, mental illness). Although positive psychology interventions (PPIs) have been shown to increase middle school students’ SWB, more research is needed to understand how baseline IEB influences post-intervention outcomes. The current study examined the effect of baseline IEB on SWB outcomes for 122 middle school students who participated in the Well-Being Promotion Program (WBPP). The WBPP is a 10-week, small group, school-based PPI for students with low SWB, as identified from universal screening of life satisfaction. The dataset analyzed is part …

Organizing Economies: Narrative Sensemaking And Communciative Resilience During Economic Disruption, Timothy Betts

USF Tampa Graduate Theses and Dissertations

This dissertation unites organizational communication, and economic theory to understand how individuals make sense of economic crises, imbed power and logic in those understandings, and construct new economic realities in the aftermath of crisis. Contra economic orthodoxy, this project conceives of economy and economics as a social construct. As a social construct, individuals organize economy and economics through discourse, make sense of through narrative, and rebuild through communication. This dissertation combines different theoretical perspectives—actor-network theory, antenarrative organization theory, and the communication theory of resilience—to recenter social scientific accounts of economic reality around communication, story, and power.

Specifically, I focus on …

Two Essays In Applied Microeconomics: Retirement, Income Inequalities, And Other Economic Indicators Of Health And Life Satisfaction, Zahra Akbari

USF Tampa Graduate Theses and Dissertations

The following proposal includes two essays in applied microeconomics. The first essay studied the relationship between income differences among siblings and the health outcomes of the individuals. Health inequalities and the factors associated with them have been a significant interest of health economists. Among those factors that can lead to health differences in adulthood, many studies have studied financial status. There are still many questions about these factors which should be answered in this area, especially about the adulthood income relative to a reference group and how it can be related to differences in adulthood health. The main goal of …

An Exploratory Investigation Of Student-Level Factors And Perceptions Of Safety In Secondary Schools Implementing Swpbis, Nicholas L. Scheel

USF Tampa Graduate Theses and Dissertations

Past and recent violent incidents (e.g., shootings, bullying) within schools in the United States have caused great concern among the public about the safety of students. Although research has shed light upon the positive and negative impacts of current crisis prevention initiatives (e.g., federal and state legislation, security cameras, trauma-informed practices) on student perceptions of safety, the breadth of literature focused on the impact multitiered systems of supports (i.e., school-wide positive behavior supports and interventions [SWPBIS]) have on student perceptions of safety is limited (Nowicki, 2020). This exploratory investigation utilized a multivariate analysis of variance to examine perceptions of safety …

Fragmentation Of Chemically Herded Oil Slicks By Obstacles: Visualizations, Flow Measurements, And Spatial Distributions, Ali Alshamrani

USF Tampa Graduate Theses and Dissertations

Chemical herders are a promising technique for treatment of oil spills in icy waters at high latitudes. However, obstacles on the water surface such as floating ice affects or interferes with all spill response countermeasures including chemical herder operations by fracturing the contracting oil slick and trapping small oil patches. Chemical herders are likely to be especially useful in containing oil spills in remote, ice-infested Arctic waters, where using booms to contain an oil slick is difficult. Much of the previous research into chemical herder has focused on the effectiveness of different types of chemical herder agents to thicken oil …

Characterizing And Explaining Prevalence And Factors Associated With Non-Fatal Opioid Overdose In Florida, Jesse M. Bell

USF Tampa Graduate Theses and Dissertations

Many factors contribute to the opioid epidemic in Florida, including, but not limited to, physician over prescribing, opioid manufacturer malfeasance (direct marketing to physicians, hospitals, and universities, as well indirect political contributions, and deliberately obfuscating the impact of the addictive properties of their various drugs), and as the epidemic approaches its 25th year, sociodemographic characteristics. This body of work examines three of these. First, because an opioid naïve persons’ typical initial encounter with the drug is through a physician, we sought to shed light on the impact of direct pharmaceutical marketing to physicians. We identified opioid providing physicians from the …

Seroprevalence Of Sars-Cov-2 Antibodies, The Gut Microbiome, And Peripherally Circulating Cytokines In Pregnant Hispanic Females, Tina Susanna Mutka

USF Tampa Graduate Theses and Dissertations

Pregnant Hispanic females have been disproportionately impacted by SARS-CoV-2 andhave experienced high rates of asymptomatic or mildly symptomatic, unrecognized infection. Acute SARS-CoV-2 infection has been associated with gut microbiome changes and altered peripherally circulating cytokine levels in symptomatic, non-pregnant individuals.

This study investigated the seroprevalence of anti-SARS-CoV-2 IgG antibodies in a sample of pregnant Hispanic females (n = 197). A sub-sample of SARS-CoV-2 seropositive and seronegative pregnant Hispanic females were followed across pregnancy and their bacterial gut microbiome was characterized, and cytokine levels measured to investigate relationships between SARS-CoV-2 serostatus, the gut microbiome, and peripherally circulating cytokine levels across pregnancy. …

Data-Driven Analytical Predictive Modeling For Pancreatic Cancer, Financial & Social Systems, Aditya Chakraborty

USF Tampa Graduate Theses and Dissertations

Pancreatic cancer is one of the most deathly disease and becoming an increasingly commoncause of cancer mortality. It continues giving rise to massive challenges to clinicians and cancer researchers. The combined five-year survival rate for pancreatic cancer is extremely low, about 5 to 10 percent, owing to the fact that a large number of the patients are diagnosed at stage IV when the disease has metastasized. Our study investigates if there exists any statistical significant difference between the median survival times and also the survival probabilities of male and female pancreatic cancer patients at different cancer stages, and irrespective of …

Evaluation Of Aluminum Dissolution, Current Density, And Pitting Patterns During Electrocoagulation, Monica Castro Carias

USF Tampa Graduate Theses and Dissertations

Electrocoagulation (EC) is a sustainable water treatment process involving the generation of coagulants on-site through the application of a voltage on metal (usually aluminum or iron alloys). The factors that impact EC system performance have been well researched, however further research is needed on the factors that impact anodic dissolution of aluminum electrodes, especially when the technology is transferred to full-scale applications. Electrode fouling is one of the factors that can impact dissolution of the anode during EC due to the formation of a protective oxide/hydroxide layer on the electrode surface. Previous studies have addressed electrode fouling by reversing polarity, …

Black children are exposed to the highest rates of negative teacher perceptions and punitive consequences. Healthy People 2020 acknowledges the significance of the first five years of child development and the various factors that promote or hinder health outcomes during this time. Furthermore, it highlights the significance of quality relationships between children and their caregivers, including their ECE teachers. Overall, Black children tend to fare better academically when they are able to engage with Black educators and other ECE professionals. However, there is recent evidence Black educators in ECE settings, specifically, also uphold racialized negative perceptions of Black students that …

“Even If You Have Food In Your House, It Will Not Taste Sweet”: Central African Refugees’ Experiences Of Cultural Food Insecurity And Other Overlapping Insecurities In Tampa, Florida, Shaye Soifoine

USF Tampa Graduate Theses and Dissertations

In the United States, resettled African refugee populations experience food insecurity at rates up to seven times higher than those of the general population. In Tampa, Florida, anthropologists have documented high levels of food insecurity among Central African refugee households since members of this population began to be resettled in the area in 2016. Utilizing an intersectional lens and drawing upon theoretical concepts such as cultural food security, navigational capital, and social reproduction, this thesis examines how Central African refugees, particularly women, experience food (in)security and other overlapping forms of (in)security as they integrate into US systems of structural inequality …

Degradation Performance Modeling And Optimal Maintenance Planning Of Deteriorating Critical Infrastructures, Hung Q. Nguyen

USF Tampa Graduate Theses and Dissertations

Serving as the backbone of the nation’s economy, a large and growing number of deteriorating critical infrastructures, such as transportation and water infrastructures, are underperforming, aging, becoming structurally deficient, and must be repaired or replaced. Due to the influence of a variety of factors (e.g., material structure, design, operation, and environmental conditions) at different phases of lifecycle and the costly data acquisition process, field degradation of deteriorating infrastructures is highly uncertain with limited degradation data. The co-location and spatial proximity between many infrastructures, such as road and water infrastructures, further makes them physically and operationally interdependent. The sheer deterioration of …

Japan’S Covid 19 Infection Rate: A Focus On Tokyo Neighborhoods, Lauren Koerner

USF Tampa Graduate Theses and Dissertations

This thesis asks, are neighborhood demographic and economic variables connected to COVID-19 infection rates in Tokyo, Japan? I hypothesize that variation in urbanization and neighborhood demographics account for Japan’s low, though not uniform COVID-19 infection rates. This thesis applies several anthropological perspectives: The biocultural perspective because I look at epidemiology of COVID 19 considering socio-cultural, economic, and ecological factors as well as biological susceptibilities. The critical biocultural perspective because I look at how structures of power and inequality may impact health and healthcare access. Biomedical/applied anthropology, well placed to study the current epidemiologic situation of COVID 19 in Japan and …

Nonparametric Estimation Of Transition Probabilities In Illness-Death Model Based On Ranked Set Sampling, Ying Ma

USF Tampa Graduate Theses and Dissertations

The ranked set sampling (RSS) design is applied widely in agriculture, environmental science, and medical research where the exact measurements of sampling units is costly, but sampling units can be ranked by a correlated concomitant variable. RSS is usually a cost-efficient alternate to simple random sampling (SRS) for selecting more representative samples. This study presents a novel methodology to investigate the nonparametric estimation of transition probabilities in illness-death model using the RSS design. We study the Aalen–Johansen estimator of transition probabilities in illness-death Markov model based on RSS design under random right censoring time and propose nonparametric estimators of the …

Antibiotic-Resistant Escherichia Coli And EnterococcusSpp. In Sand And Water At Tampa Bay Beaches, Jennifer K. Sabater

USF Tampa Graduate Theses and Dissertations

As antibiotic resistance in the environment continues to rise there is an increased concern that infections may become harder to treat as bacteria acquire genes for multidrug resistance. Recreational beach waters in the Tampa Bay area are routinely monitored by the Florida Department of Environmental Protection for the presence of fecal indicator bacteria (FIB) such as Escherichia coli and enterococci. Exceedances of beach action values (BAV) 235 CFU/100 mL (E. coli) and 70 CFU/100 mL (enterococci) indicate the presence of fecal contamination which is associated with an increased risk of disease for beachgoers. Antibiotic-resistant E. coli and Enterococcus spp. have …

A Theoretical Framework For Understanding Breast Cancer Survivor's Post-Treatment Lived Experiences In An Educational Program: A Qualitative Data Analysis, Katherine Jinghua Lin

USF Tampa Graduate Theses and Dissertations

Breast cancer (BC) is the most prevalent type of cancer among women and the most common cancer diagnosis for all the population in the United States. Early screening and treatment for BC have improved the prognosis for breast cancer survivors (BCSs) and increased survival rate. Current evidence showed insufficient data related to BCSs’ post-treatment symptoms, coping issues, and availability and impact of educational and support programs associated with breast cancer survivorship.

The overall purpose of this qualitative data analysis research project is to explore and identify BCSs’ perceptions (post-treatment) of physical, cognitive, and psychological symptoms experienced, as well as perceptions …

The Use Of Acceptance And Commitment Training To Improve Teacher Interactions With Students, Taylor Raaymakers

USF Tampa Graduate Theses and Dissertations

Teachers in classrooms with students who engage in challenging behavior often experience high levels of stress and may leave the profession. Few research studies have evaluated interventions to decrease teacher stress. Therefore, this study assessed the use of Acceptance and Commitment Training (ACTr) with teachers for decreasing stress and increasing positive interactions with students. The ACTr intervention consisted of both a one-time training and subsequent activities throughout the intervention phase of the study. Two self-report measures were administered during baseline and post follow-up observations. These self-report measures provided information on the levels of psychological distress the teachers were experiencing and …

Nevertheless, advances in artificial intelligence (AI) in the big data era have increased the capability to capitalize on and benefit from the collection of this private data. Such private data is being used for various machine learning (ML) applications in different domains, such as marketing, insurance, financial services, mobility, social …

"Are We Done?": The Minimization Of Covid-19 And The Individualization Of Health In The United States, Cassidy R. Boe

USF Tampa Graduate Theses and Dissertations

As the death toll from Covid-19 in the United States exceeds 1 million in just over two years, more variants continue to emerge, threatening more waves of Covid-19 and ultimately, more deaths. Despite this, mask use continues to decline, and one third of Americans say that the pandemic is over. The Centers for Disease Control and Prevention (CDC) has been central in publicly disseminating biomedical knowledge using Twitter. The CDC’s Twitter account (@CDCgov) shares information related to the spread of Covid-19, including mitigation measures such as mask recommendations and vaccine information. I have conducted a narrative analysis of the replies …

Continuous Effort Required To Maintain Populations Of Outplanted Acropora Cervicornis In The Florida Reef Tract, Usa, Tiffany S. Boisvert

USF Tampa Graduate Theses and Dissertations

The degradation of coral reefs due to natural and anthropogenic stressors has resulted in the expansion of coral restoration projects worldwide. In the Caribbean region, most restoration efforts focus on outplanting Acropora cervicornis, once a dominant branching coral, now found predominantly in spatially isolated populations. Thousands of A. cervicornis colonies are propagated within nurseries and outplanted onto degraded reefs every year. However, monitoring the long-term growth and survival of outplanted corals has been limited by financial, physical, and temporal constraints. In the current study, we assessed the long-term success of A. cervicornis restoration by determining the relationship between current populations …

Outcomes Of A Periodic Exposure Assessment Of Workers At A University Campus, Logan M. Armagast

USF Tampa Graduate Theses and Dissertations

Standards promulgated by the Occupational Safety and Health Administration (OSHA)are applicable to most businesses in the private sector, however, state and local government entities are not under OSHA’s jurisdiction. Universities that receive public funding fall under the category of state and local government entities and, unless an OSHA-approved State plan explicitly states otherwise, they are not required to demonstrate compliance with OSHA standards and are not subject to OSHA inspections. Without being constrained by federal regulation, those responsible for ensuring the health and safety of employees at publicly funded universities have some leeway in their methods for evaluating the conditions …

Health And Friendships Of Lgbtqia+ College Students, Komal Asim Qidwai

USF Tampa Graduate Theses and Dissertations

Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, Asexual and Others (LGBTQIA+) college students continue to face discrimination in seeking healthcare, having to navigate lack of access, heteronormative practices and protocols, and biased attitudes, even when accessing university health services. Moreover, LGBTQIA+ college students are unlikely to be able to rely on traditional sources of support such as family, and have a need to create a sense of home, by making friends. In this thesis, I explore friendships as an avenue through which these students seek health information and knowledge. I argue that health and friendship intersect in the lives of LGBTQIA+ …

Spillover Effects In Product Customization, Samuel Babu Sekar

USF Tampa Graduate Theses and Dissertations

Product customization is increasingly being offered as consumers interact with businesses online. When consumers customize a product, they often choose from among multiple, inter-related categories. Thus, the choices made in a prior category could influence choices in later categories (spillover effect). Currently, marketers attempt to nudge consumers to choose more expensive/profitable options by preselecting these options (explicit reference). In this dissertation, I explore whether implicit references can be employed to generate a spillover effect. Implicit references are generated by arranging the options within a category in either descending or ascending price order, with descending price order favoring the selection of …

The Effect Of Racial And Ethnic Identity Salience On Online Political Expression And Political Participation In The United States, Jonathon Smith

USF Tampa Graduate Theses and Dissertations

How close an individual identifies with their race or ethnicity can affect how individuals behave as political actors. Racial identity can affect how individuals express their political beliefs on social media sites or participate in political activities. However, does political expression on social media, particularly Facebook and Twitter, affect levels of political participation? The purpose of the project is to examine the relationship between racial and ethnic identity, online political expression, and political participation among the three largest racial and ethnic groups in the United States. Specifically, this project aims to answer whether online political expression mediates the relationship between …

Etiology Of Sterile Intra-Amniotic Inflammation: An Exploratory Study, Zoe M. Taylor

USF Tampa Graduate Theses and Dissertations

Preterm birth is the event of spontaneous birth prior to 37 weeks of gestation. In the United States, 1 in 10 babies are born prematurely. Low gestational age has been linked with increased morbidity and mortality. Preterm birth is multifactorial, where a myriad of contributors have been identified to include inflammation, chorioamnionitis, and inflammatory conditions to include hypertension and diabetes. To further explore the role inflammation plays in low gestational age, a literature review was done using PubMed. Two classes of inflammation quickly emerged: Pathogen born intra-amniotic inflammation and Sterile intra-amniotic inflammation. The latter form of inflammation has no identifiable …

A Technique-Based Approach To Structure-From-Motion: Applications To Human-Coastal Environments, Robert Van Alphen

USF Tampa Graduate Theses and Dissertations

Photogrammetry is a method by which physical information can be extracted from thecorrespondence of 2-dimensional images. In the geosciences, Structure-from-Motion (SfM) photogrammetry is a technique that has seen considerable interest in the past decade of research. Here I present three case studies of various scope and methodologies which can inform the use of SfM in the geosciences. First, I discuss the theoretical and algorithmic basis of SfM photogrammetry and its uses thus far in the geosciences. Chapters two through four show specific studies which highlight several approaches to SfM and the data which can be produced. Chapter five then concludes …

Depersonalized, Dysregulated, And Demanded: The Impact Of Burnout On Appraisal And Emotional Events, Katrina M. Conen

USF Tampa Graduate Theses and Dissertations

A widely studied construct, burnout is a chronic disease that is considered to develop over time (Maslach et al., 2001). Burnout has been related to a number of pertinent outcomes including increased job turnover, decreased job satisfaction, and poor mental and physical health outcomes (Ahola, 2007). However, little work has yet to be done concerning the role burnout may play in the appraisal of work events and the subsequent psychological construction of emotional episodes. The current study addresses the tension between the chronic affective dysregulation associated with burnout and the acute construction of an emotional episode. Results support the idea …

Ceramide-1-Phosphate: A Novel Regulator Of Golgi Fragmentation, Golgi-Er Vesicle Trafficking, And Anaplasma Phagocytophilum Pathogenesis, Anika Nayar Ali

USF Tampa Graduate Theses and Dissertations

Anaplasma phagocytophilum, the etiologic agent of human granulocytic anaplasmosis (HGA), is a tick transmitted obligate intracellular bacterium that infects granulocytes, bone marrow progenitor cells and endothelial cells. HGA exhibits symptoms of febrile illness including fever, chills, headache, malaise, leukopenia and elevated liver enzymes which are treatable by antibiotics. However, elderly and immunocompromised patients are at a greater risk of developing fatal complications. Inside the host cell A.phagocytophilum resides in host cell derived vacuole called A.phagocytophilum occupied vacuole (ApV) where it undergoes its biphasic lifecycle. Being an intracellular pathogen, A.phagocytophilum relies heavily on nutrient acquisition from host cell and to obtain …

Chronological Accumulation Of Microplastics In The Gulf Of Mexico And Their Acute Effects On Coral Bleaching, Martina M. Plafcan

USF Tampa Graduate Theses and Dissertations

Microplastics have accumulated in the environment since plastic production began. They have spread to all areas of the globe from marine trenches to mountains and they can be harmful to organisms. However, research on microplastics has only recently begun so it is unclear how they have changed over time in many regions of the ocean and how current oceanic concentrations might affect marine life. Additionally, organisms such as corals are under stress and have been declining due to climate change, so it is not yet known if microplastics exacerbate these threats. My thesis addressed these gaps in the literature by …
