Surviving A Broken System: Synergies Between Solidarity Economies And Sustainable Development Goals, Julie Beach

USF Tampa Graduate Theses and Dissertations

Capitalism has created problems including wealth polarization, rapid depletion of natural resources, and pervasive systemic societal issues. Hard work is not enough to solve the unequal distribution and barriers preventing access to necessities. Sustainable Development Goals (SDGs) were created to remedy the harsh reality of global inequities and negative environmental impacts by working towards a more just and equitable future for all. Solidarity Economies (SE) offer an alternative framework to achieve these goals.

This research used multiple qualitative methods to investigate the synergies between SE and SDGs in a growing urban environment. St. Petersburg, FL struggles with affordable housing, food …

Designing A Messaging Strategy To Improve Information Security Policy Compliance, Federico Giovannetti

USF Tampa Graduate Theses and Dissertations

Lack of employee compliance with information security policies is a key factor driving security incidents. Information security practitioners struggle to enforce policy compliance while employees try to curtail safeguards in favor of expediency and other perceived business goals. Several studies have shown individual and organizational factors influencing this type of employee behavior. However, few have recommended management-level interventions that can be used as a solution framework by information security practitioners.

This research utilized the Design Science Research (DSR) methodology to develop a management-level intervention based on a messaging strategy that aims to help information security practitioners improve the information security …

The Impact Of Critical Illness Insurance Among Older Adults In China, Jiaosi Li

USF Tampa Graduate Theses and Dissertations

Although China has made considerable progress towards universal health insurance coverage, high out-of-pocket medical expenditures due to catastrophic illnesses (e.g., cancer, heart attack, or stroke) remain a concern. To address this concern, the Critical Illness Insurance (CII) program providing additional coverage for high medical expenditures was introduced in 2012. We combine data on the timing of CII implementation across prefecture cities in China with the China Health and Retirement Longitudinal Study (CHARLS) to examine its impact on medical expenditures, inpatient utilization, health outcomes, household consumption and savings. To account for the staggered implementation across regions, we employ the Difference-in-Differences (DiD) …

An Anthropology With Human Waste Management: Non-Humans, The State, And Matters Of Care On The Placencia Peninsula, Belize, William Alex Webb

USF Tampa Graduate Theses and Dissertations

The management of human waste is a seldom studied phenomenon in anthropology. Yet across the globe, in countries both rich and poor, it presents pervasive and difficult to tame problems. This dissertation draws on complimentary theories of management and entanglements to explore the practices and processes of organizing human waste on the Placencia Peninsula, Belize. The results illustrate how problems are conditioned and defined by messy relations between institutions, people, technologies, materials, and ecological life.

Fieldwork and analysis for this work was a culmination of years of interdisciplinary collaboration between other anthropologists and engineers at the University of South Florida. …

Saudi Pre-Service Teachers’ Beliefs And Practices Regarding Digital Technology In Early Years Education: A Qualitative Case Study, May Mohammed Alyaeesh

There was an absence of effective practices, participants’ technical competence was very basic, and their recognition …

Essays In Political Insider Trading, Jan Hanousek Jr.

USF Tampa Graduate Theses and Dissertations

In this dissertation, I examine senators’ stock transactions, filled both electronically and on paper, between 2012 and 2020 to assess the extent of politicians’ insider trading and its impact on the market. The results suggest that senators use inside political information when investing. I find that both the estimated realized returns and buy-and-hold market abnormal returns are positive and significant. The extent of returns depends on the various personal characteristics of senators. Furthermore, there is evidence that senators attempt to obscure their more profitable trades, further suggesting that they use inside information when trading.

To extend traditional return-based methods, I …

A qualitative multi-case study design was used to collect data from semi-structured interviews and on-site observations for four Saudi early childhood teachers in two Montessori classrooms in Saudi Arabia. The data were thematically analyzed manually and with NVivo software. The study results showed that the teachers encouraged children’s independence and freedom of choice in work time and during the classroom day, but limited their freedom during mini-lessons and circle …

American Horse Power During The Great War, Hanna K. Lipsey

USF Tampa Graduate Theses and Dissertations

This dissertation charts the significant, if understudied, history of American horses during the era of World War I, from roughly 1914 to 1919. Its chapters trace how the US Army acquired, used, cared for, and ultimately demobilized horses over the course of that conflict. Beginning with their acquisition, via either an Army Horse Breeding Program or a complicated buying process, horses faced a complex introduction into military service. Life for these animals did not get any easier once they reached the European front. Although the US military was beginning to replace horses with motor trucks and tractors, horses remained central …

Towards More Task-Generalized And Explainable Ai Through Psychometrics, Alec Braynen

USF Tampa Graduate Theses and Dissertations

In this work, we propose that adopting the methods, principles, and guidelines of the field of psychometrics can help the Artificial Intelligence (AI) community to build more task-generalizable and explainable AI. Three arguments are presented and explored. These arguments are that psychometrics can help by providing 1) a framework for formulating better datasets, 2) psychometric AI data that can lead to models of generalization in AI, and 3) explainable AI through more informative evaluations.

Generative Spatio-Temporal And Multimodal Analysis Of Neonatal Pain, Md Sirajus Salekin

USF Tampa Graduate Theses and Dissertations

Neonates can not express their pain like an adult person. Due to the lacking of proper muscle growth and inability to express non-verbally, it is difficult to understand their emotional status. In addition, if the neonates are under any treatment or left monitored after any major surgeries (post-operative), it is more difficult to understand their pain due to the side effect of medications and the caring system (i.e. intubated, masked face, covered body with blanket, etc.). In a clinical environment, usually, bedside nurses routinely observe the neonate and measure the pain status following any standard clinical pain scale. But current …

Integrating Psychopathy Into Prominent Developmental/Life-Course Theories, Eva M. Fontaine

USF Tampa Graduate Theses and Dissertations

Despite empirical research identifying psychopathy as one of the most robust predictors of criminal behavior, calls to integrate psychopathy into criminological theory have largely been unrequited. Within criminological theory, the construct of psychopathy has been proposed to best fit in the developmental/life-course (DLC) paradigm. As such, the purpose of this dissertation was to explore the theoretical integration of into psychopathy into three DLC theories: (1) Moffitt’s (1993) Dual Taxonomy, (2) Gottfredson & Hirschi’s (1990) General Theory of Crime, and (3) DeLisi’s (2009) Unified Theory of Crime. In doing so, the three studies in this dissertation employed the Pathways to Desistance …

Beyond Health And Animal Rights: A Study In Black Veganism, Wendy J. Rib

USF Tampa Graduate Theses and Dissertations

Veganism, or the avoidance of animal products, has been recognized by nutritionists and food scientists as a lifestyle choice associated with good health and lower prevalence of diabetes, obesity, hypertension, and heart disease. However, the choice to eschew all animal products is frequently more than just a diet. Many people practice veganism as part of a larger reformative social movement, seeking permanent change in food structures, advancing policies in animal welfare and transforming their everyday lives in the quest for cultural acceptance. Although the number of people who identify as vegans appears to be growing, it is often assumed that …

Heidegger And The Origin Of Authenticity, John J. Preston

USF Tampa Graduate Theses and Dissertations

Since the publication of Sein und Zeit in 1927, scholars have coupled Martin Heidegger’s reflections on authenticity with a rich tradition of thought which reminds us that philosophy can, from time to time, function as a catalyst for self-discovery. While this function is an undeniable feature of Heideggerian authenticity, I would like to suggest that it is secondary to the role that authenticity plays in Heidegger’s philosophical investigations. By analyzing the full phenomena of authenticity and tracing its first technical uses back to Heidegger’s early lectures on Aristotle, I show that Heidegger’s methodological breakthrough in the early 1920s, the development …

Study On New Strategy Toward Gold(I/Iii) Redox Catalysis, Shuyao Zhang

USF Tampa Graduate Theses and Dissertations

This dissertation mainly contains three parts: 1) the study of ligand assisted gold oxidative addition toward aryl iodide to achieve the alkene difunctionalization. 2) The selective arylation reaction via electrochemical anode oxidation promoted gold redox chemistry. 3) The π acid reactivity of gold redox chemistry under electrochemistry conditions.

In the first part, the gold-catalyzed intermolecular oxyarylation of alkene is reported. This work employed the oxidative addition of aryl iodide to Me-DalphosAu+ for the formation of Au(III)-Ar intermediate. The better binding ability of alkene over O nucleophiles ensured the success of intermolecular oxyarylation, giving desired products with broad substrate scope and …

Longitudinal Associations Among Life Values, Alcohol Use, And Alcohol Abuse Symptoms From Adolescence To Adulthood, Connor Habecker

USF Tampa Graduate Theses and Dissertations

Investigating life value trends, the pro-social and anti-social characteristics that play a role in decision making, is an understudied field in adolescents. In addressing adolescent alcohol consumption as a public health concern, life values may provide needed background in understanding and influencing adolescent behavior toward pro-social values and away from known risk factors, such as alcohol consumption. By modeling life value trends of adolescents and the associations between each life value and the outcomes of alcohol use and alcohol abuse, there may be primordial level intervention opportunities as opposed to the current, largely ineffective, tertiary level interventions. This thesis utilizes …

Magnetism In Doped And Hybrid Two – Dimensional Transition Metal Dichalcogenides, Nalaka Kapuruge

USF Tampa Graduate Theses and Dissertations

In recent years, spintronics has gained increasing interest due to the possibility of storing and processing information through the manipulation of both the charge and spin of an electron. Dilute magnetic semiconductors are ideal for the fabrication of such devices as they display carrier-mediated ferromagnetism which allows the electronic control of magnetism. Transferring these properties into the two-dimensional (2D) realm is very attractive for both fundamental research and novel applications. The recent discovery of long-range magnetic order in 2D materials has attracted a growing effort in the search for new functional 2D materials that can display ferromagnetic properties at room-temperature. …

Preventing Variadic Function Attacks Through Argument Width Counting, Brennan Ward

USF Tampa Graduate Theses and Dissertations

Format String attacks, first noted in June 2000 [1], are a type of attack in which anadversary has control of the string argument (the format string) passed to a string format function (such as printf). Such control allows the attacker to read and write arbitrary program memory. To prevent these attacks, various methodologies have been proposed, each with their own costs and benefits. I present a novel solution to this problem through argument width counting, ensuring that such format functions cannot access stack memory beyond the space where arguments were placed. Additionally, I show how this approach can be expanded …

Perceptions Of Workplace Discrimination: A Closer Look, Jeremiah Doaty

Furthermore, this research investigated whether different types of PWD related to job attitude variables differently across different demographic groups (race, sex, and age). Participants of this study consisted of 1,610 employees from multiple southeastern public universities. Results from this study found that psychological diversity climate had the strongest relationship to the different dimensions of PWD, followed by hostile attribution bias and perceived group dissimilarity. Blacks and Black females reported the most …

Do Sociability Expectancies Moderate Social Anxiety Predicting Alcohol Consumption Following A Social Stressor Speech Task, Jacob A. Levine

USF Tampa Graduate Theses and Dissertations

Alcohol use disorder (AUD) and social anxiety disorder (SAD) are two of the most common and chronic psychiatric conditions in the United States. Research indicates individuals with SAD are more likely to meet lifetime criteria for AUD and experience greater AUD symptomatology and severity. Theories explaining this connection are limited, with most built upon tension reduction principles not specific to SAD; however, a recent biopsychosocial model focuses on factors specific to SAD, such as drinking to cope with states of high negative affectivity and arousal. Despite high rates of comorbidity, and more severe AUD presentation, the literature is mixed regarding …

African American Males' Perception Of Factors That Contribute To Success In Higher Education, Gary D. Oliver

USF Tampa Graduate Theses and Dissertations

Over the past decades, many studies have concluded that African American students' college completion rate and success lag far behind other students attending college in the United States (The JBHE Foundation, Inc., 2006). More specifically, these studies have confirmed that African American male students' success rates remain disproportionally low compared to other ethnic male groups. Unfortunately, few notable studies identifying African American males achieving higher education or completing their academic pursuits have been presented as part of the Black male student narrative.

This study aimed to understand better the resources and experiences that positively affect African American males who completed …

Assessment And Prevention Of Bacterial Regrowth In Stored Household Water In Eastern Coastal Madagascar, Lauren Judah

USF Tampa Graduate Theses and Dissertations

As of 2020, diarrheal diseases were the leading cause of death in Madagascar. A major cause of diarrheal illness is contaminated water, and one crucial aspect of preventing contaminated water is safe household storage. Bacterial regrowth between point-of-collection and household storage has been well established in literature. A frequently implicated source of regrowth is the storage container’s biofilm, which is a community of varying bacteria enclosed in a “slimy” extracellular polymeric substance that forms on surfaces in wet environments and anchors bacteria to those surfaces. The overall goal of this thesis was to quantify and control bacterial regrowth in household …

Design And Assessment Of A Novel Edna Survey Method For The Eastern Indigo Snake (Drymarchon Couperi), Emily K. Galbraith

USF Tampa Graduate Theses and Dissertations

1. Accurate information about species range declines is the cornerstone of effective conservation when habitat loss drives biodiversity loss. The Eastern Indigo snake (Drymarchon couperi) is an apex predator in Florida and, like many other native Florida species, is threatened by widespread habitat destruction. Environmental DNA (eDNA) monitoring of this elusive snake would provide a low-risk and low-cost approach to expand our knowledge of the species’ range and distribution.

2. We designed and tested an eDNA assay that can detect the presence of Eastern Indigo snake from soil samples of their natural habitat. This assay was …

Utilizing Maternal Investment Strategies Of Sharks To Develop Management Tools To Aid In Shark Conservation, Dennis Deeken

USF Tampa Graduate Theses and Dissertations

Every generation, breeding females and males repopulate ecosystems with the next generation of offspring. Two models link maternal investments in offspring size and number to natural selection processes. In unstable resource environments, bet-hedging models predict a conservative tradeoff in maternal investments resulting in moderate egg size and clutch size within a given range of sizes for a given species. r/K selection models make predictions on maternal investments across species. In unstable resource environments, r-selected species invest in large broods of small offspring. In stable environments, K-selected species invest in small broods of large offspring. The maternal risk management model predicts …
