Hidden Struggles Within The Mental Healthcare Workplace, Tammy V. Smith

USF Tampa Graduate Theses and Dissertations

For decades, the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) have reported on the worldwide pervasiveness and increasing societal costs associated with Adverse Childhood Experiences (ACEs). A recent post on the WHO website cited recent scientific research (2022) indicating the magnitude of harmful effects attributed to ACEs, even classifying them as “violence against children.” Esaki and Larkin (2013) indicate that ACEs are prevalent among many social service professionals, including mental health clinicians.

This study uses mental health clinicians as the sample population to identify the impact of ACEs on job performance. Findings from a volunteer …

Neural And Cardiac Mechanisms In Friedreich's Ataxia With Patient-Derived Ipscs, Mariana Burgos Angulo

USF Tampa Graduate Theses and Dissertations

Friedreich's ataxia (FA) is an autosomal recessive disease caused, in most cases, by a GAA trinucleotide repeat expansion in the first intron of the frataxin (FXN) gene, which results in transcriptional repression of the encoded protein frataxin. FA is a progressive neurodegenerative disorder, but the primary cause of death is hypertrophic cardiomyopathy, which occurs in 60% of the patients. Several functions of frataxin have been proposed, but none of them can fully explain why its deficiency causes the FA phenotypes nor why the most affected cell types are neurons and cardiomyocytes. It is possible that frataxin affects neural and cardiac …

Chemical Investigation And Drug Discovery Potential Of Terpenoid Secondary Metabolites From Three Deep-Sea Irish Soft Corals, Joshua Thomas Welsch

USF Tampa Graduate Theses and Dissertations

Secondary metabolites produced primarily by terrestrial plants and animals have provided the basis for treatments and cures of human diseases as far back as historians have been able to probe. However, recent technological advances including the self-contained underwater breathing apparatus, and even further remotely operated vehicles, have allowed researchers a unique opportunity for targeted collection of marine organisms at depths previously thought to possess conditions unsustainable for life as was understood. This has afforded a glimpse into the potential for not only life, but the potential for new biochemical adaptations developed over billions of years that have been evolutionarily developed …

Remnants Of Educational Leadership And Desegregation Etched In The Memories Of Black Educational Leaders: An Oral History, Janice Barge Clarke

USF Tampa Graduate Theses and Dissertations

In this study the experiences of Black (a.k.a. African Americans/ Negroes) educationalleaders were explored focusing on the period during the transition to a more desegregated public- school setting in the state of Florida. Using retrospective storytelling and reflections of ‘leading’ during desegregation, the lived experiences of those in educational leadership roles were captured in the form of oral histories and analyzed using critical race theory. The effects of desegregation is recounted from their vantage point, from the dissolution of the ‘all Black’ schools to the impact it had on the communities. The research question was: What are the stories told …

Joint Models For Repeated Measured, Non-Normally Distributed Multilevel Data, Weiwei He

USF Tampa Graduate Theses and Dissertations

Clinical trials have tended to collect both survival information and longitudinal biomarkers, as well as other covariates. In order to better assess the severity of diverse diseases, we need to collect various longitudinal outcomes. Furthermore, longitudinal data could consist of a number of different measurements of varying types. The multilevel item response theory (MLIRT) model has been widely used in several fields such as public health and health sciences for multivariate longitudinal outcomes. Joint models combining the longitudinal and survival processes, as well as the relation between them, have been developed to minimize bias and improve the efficiency of estimates. …

“Good War” On The Cool Medium: The Cold War's Influence On The Portrayal Of World War Ii On American Television, Michael A. Losasso

USF Tampa Graduate Theses and Dissertations

This dissertation is a cultural history of the Cold War’s influence on the portrayal of World War II on American television. In it, I chronicle the production, reception, and presentation of the war of three prominent American-produced documentary series from three periods of the Cold War – Victory at Sea (1952-1953), The Twentieth Century (1957-1966), and The Unknown War (1978). The dissertation posits that from the 1940s-1960s, the television portrayal of World War II was an embodiment of the values- that the United Sates was “fighting” for through a “triumphalist” narrative of a “just war” which recast the role of …

Development And Evaluation Of The Values-Centered Assessment Tool (Vcat) To Inform Culturally Responsive Behavioral Parent Training Intervention, Daniel Kwak

USF Tampa Graduate Theses and Dissertations

In this study, we aimed to develop and evaluate the use of the Values-Centered Assessment Tool (VCAT) intended for use by behavior analysts to design and provide culturally responsive behavioral parent training intervention for children with behavioral difficulties who are from diverse cultural backgrounds. The study was completed in two phases using a mixed methods research approach. In Phase 1, the VCAT was developed through review of literature and interviews with behavior analysts and was validated through an expert panel review. Major revisions made from the initially developed VCAT included the addition of (a) a questionnaire for parents, (b) information …

Advanced Analytical Method Development: From Highly-Enrolled Classroom To Data-Intensive Proteomics, Laxmi Sinduri Vuppala

USF Tampa Graduate Theses and Dissertations

In analytical chemistry, method development is key to identifying, separating, and quantifying chemical components of interest systems. The chemical aspects are fundamental to understanding the subject of any analytical system, whether in academic research, industry, or government. These methodologies serve as a bridge between the classroom, where students are taught to be curious and enlightened, and research, where one strives to contribute. The Ph.D. dissertation integrates advanced methodologies in basic and applied research and advanced instrumentation, but the core criteria for validation remain the same. As part of chemical education curriculum development, a large cohort of undergraduates performed two gas …

Essays On Opioid Related Issues, Minglu Sun

USF Tampa Graduate Theses and Dissertations

Strong empirical evidence points towards a significantly higher prevalence of opioid consumption among people receiving disability benefits (DB) than in the general population of the United States. However, no previous research established a causal relationship between the decision to award DB to applicants and their subsequent opioid use. We aim to contribute towards filling this gap. There are channels through which awarding DB may both increase and depress opioid consumption, and thus, ex-ante, the sign of a potential causal relationship is ambiguous. To correct for the treatment endogeneity, since an individual’s age at the time of the decision on an …

Healthcare Iot System And Network Design, Halil Ibrahim Deniz

USF Tampa Graduate Theses and Dissertations

The developing IoT concept offers many opportunities to service providers in the medical field. However, the functionality of the developed systems is increasing day by day, and it brings many different problems. One of the most important problems is the transmission of biomedical data of real-time monitoring systems to the medical server with the least delay. Network architectures are changing to meet the changing needs of densely connected devices, and “computing at the edge” is the new architectural approach emerging in IoT networks. This architecture is more dynamic than computation in the cloud because it enables data processing at each …

Advising Latinx Students For Postsecondary Career And Technical Education (Cte): A Qualitative Study Of High School Counselors In Florida, Adriana C. Magana

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to gather detailed descriptions of information, resources, and interventions that school counselors use to inform and advise Latinx students of postsecondary CTE options. A qualitative study with semi-structured interviews was conducted to understand how Florida school counselors advise Latinx students for postsecondary Career and Technical Education (CTE) options. A three-prong conceptual framework was used, drawing from Bourdieu’s (1986) Theory of Cultural Capital, career development theories, and the American School Counselor Association’s (ASCA) National Model.

Ten school counselors working in public high schools in Florida participated in semi-structured interviews for this study. Altogether, the study’s …

Functional Morphology And Taphonomy Of Ordovician–Silurian Diploporan Echinoderms, Stephen Ashley Hill

USF Tampa Graduate Theses and Dissertations

Diploporan echinoderms were one of the most speciose groups of stemmed echinoderms during the Ordovician. Despite this widespread abundance, the fossil record of diploporan fauna consists primarily of incomplete specimens, with complete specimens being rare. While the theca, or body, is more commonly preserved, the feeding appendages and the attachment structures (i.e. stems or holdfasts) are seldomly preserved. Insight into these features is highly valuable to the understanding the paleoecology, like the feeding and respiratory strategies, of these enigmatic creatures.

One group of diploporan echinoderms which does have an extensive fossil record, is the Holocystites Fauna, primarily known from the …

Revisiting ‘Our’ Place On Campus: A Queer(Ed) And In-Depth Interview Study Of Qt Resource Professionals In Higher Education, Kristopher Andrew Oliveira

USF Tampa Graduate Theses and Dissertations

This dissertation offers an interactional, structural, and theoretical analysis of the experiences of Queer and Trans (QT) resource professionals in higher education. Data from the empirical chapters draws on 41 in-depth semi-structured interviews that conducted with QT resource professionals from 19 different states across the United States. The interactional and structural chapters reveal tensions between institutional commitments to doing equity work on college campuses and the neoliberal and institutional barriers that QT resource professionals experience in promoting and fostering institutional equity on campus. The third substantive chapter offers a queer of color critique – through Muñoz’s (2019) notion of queer …

Inflammatory Bowel Disease & Social (In)Visibility: An Interpretive Study Of Food Choice, Self-Blame And Coping In Women Living With Ibd, Jessica N. Lolli

USF Tampa Graduate Theses and Dissertations

This dissertation is an interpretive project that uses autoethnography and qualitative interview methods to understand the role Inflammatory Bowel Disease (IBD) plays in women’s quality of life and interpersonal relationships. It focuses on the impacts on patients of dietary changes and how food choice serves to make this ordinarily “invisible” illness visible to others, leading to unwanted exposure. Using Erving Goffman’s stigma theory and its extensions in studies of chronic illness, I demonstrate that IBD is characterized by layers of stigma because it creates situations in which patients are forced to disclose their illness even if they are not ready …

Inland Tropical Cyclone Intensity Decay In The Continental United States, Yijie Zhu

USF Tampa Graduate Theses and Dissertations

Tropical cyclone (TC) hazard preparation is mostly focused on coastal cities with less attention typically paid to inland regions. The impact of TCs that propagate far inland is often underestimated and can cause unexpected loss of life and economic loss. This dissertation aims to understand the decay process of TCs during the post-landfall stage by answering three main research questions: (1) What are the general patterns of inland tropical cyclones, including spatial variations, decay rates, and translation speeds? (2) Are there temporal changes in the intensity decay from inland moving hurricanes? (3) How is the hurricane post-landfall dissipation related to …

A Tale Of Two Art Programs: Art & Identity For People With Disabilities, Melinda Leigh Maconi

USF Tampa Graduate Theses and Dissertations

This dissertation explores the relationship between disability and art in individual and organizational narratives told in the context of art programs that are designed to provide meaningful and inclusive experiences for people with disabilities outside of “art therapy.” Findings of narrative and thematic analysis of the websites of two non-profit disability centered arts education organizations, autobiographical sketches of disabled artists, and in-depth family history interviews with parents of people with disabilities suggest that the clear cut boxes created by scholarly and social movements narratives of disability do not map neatly onto the lived experiences of people with disabilities, their families, …

Nano-Optical Imaging Of 2d Materials In The Quantum Regime, Hana Nazari Hrim

USF Tampa Graduate Theses and Dissertations

Chemical vapor deposition (CVD) growth of atomically thin 2D materials, such as transition metal dichalcogenides (TMDs), is a complex process that has not been completely understood. Large-scale growth of monolayer TMDs often leads to polycrystalline films with heterogeneous morphological and optical properties. Previous optical studies of 2D materials by far-field photoluminescence (PL) provided insights into CVD growth mechanisms of simple crystals, which were, however, limited in spatial resolution due to the diffraction limit. Here we performed correlated morphological and tip-enhanced PL (TEPL) imaging of CVD-grown polycrystalline monolayer molybdenum diselenide (MoSe2) flakes with heterogeneous optical response. We observed nanoscale spatial variations …

Digital Realness: Queer Intimacy In Contrapoints, William S. Beaman

USF Tampa Graduate Theses and Dissertations

Digital media comprises a diverse ecology of creative genres, institutions, communities,platforms, and entrepreneurial businesses. Yet despite its practical association with variegated social forms, digital mediation as such is often theorized as a logic of homogenization, problematically obscuring its heterogeneously contested character. This article reconceives mediation as an irreducibly multi-scalar and heterogeneous infrastructure, recasting online activity as contested participation in wider social contexts. I am contributing to a counter tendency in media studies that methodologically treats digital forms as polysemic, ambiguous and contested, rather than necessarily homogenizing, in the context of specific cases. Drawing out the theoretical implications of this methodology …

Deep Learning And Feature Engineering For Human Activity Recognition: Exploiting Novel Rich Learning Representations And Sub-Transfer Learning To Boost Practical Performance, Ria Kanjilal

USF Tampa Graduate Theses and Dissertations

A significant gap exists in our knowledge of how domain-specific feature extraction compares to unsupervised feature learning in the latent space of a deep neural network for a range of temporal applications including human activity recognition. This dissertation aims to address this gap specifically for human activity recognition using acceleration data. To ensure reproducibility, we use two publicly available datasets, UniMiB-SHAR and ExtraSensory, with a well-established history in the human activity recognition literature. We methodically analyze the performance of 64 different combinations of i) learning representations (in the form of raw temporal data or extracted features), ii) traditional and modern …

Juvenile Homicide Offenders: A Life-Course Perspective, Norair Khachatryan

USF Tampa Graduate Theses and Dissertations

Murder by offenders under the age of 18 is a cause for public concern, despite the overall decrease in the rate of juvenile-perpetrated homicide since 1994. Due to several rulings by the U.S. Supreme Court (i.e., Miller v. Alabama, 2012), the likelihood that convicted juvenile homicide offenders (JHOs) will be released from prison has increased. Accordingly, it is important to examine these offenders’ long-term readjustment to society after their release. Using a mixed-method approach, the present study was designed to explore the factors that influence whether JHOs reoffend and their reoffending patterns, over a period of approximately 35 years. Another …

Stability And Interaction Analysis Of Inverter-Based Resources In Power Grids, Li Bao

USF Tampa Graduate Theses and Dissertations

The increasing penetration of inverter-based resources (IBRs) introduces some unexpected dynamic issues, including low-frequency oscillations. To investigate these phenomenon, a laboratory-scale grid-following voltage-source converter (VSC) system is implemented to demonstrate weak grid oscillations. Grid-following control is applied in VSC to provide active power, reactive power or ac voltage control. The test bed is also replicated in electromagnetic transient (EMT) simulation environment (MATLAB/SimPowerSystems) for benchmark purpose. Case studies are carried out to demonstrate low-frequency oscillations under real power/ac voltage or real power/reactive power control. An analytical model is carried out to examine the stability condition and compared with EMT or hardware …

Examining The Social Validity Of Parent Training: Post-Participation Parent Perceptions And Reflections Of Group Triple P, Nycole C. Kauk

USF Tampa Graduate Theses and Dissertations

Child behavior problems are highly prevalent and impactful on the child and their family system, bringing both short-term and long-term consequences (Sanders, 2012). Many risk factors for child behavior problems are modifiable via the use of Behavioral Family Interventions, such as behavioral parent training programs (Kazdin, 1991). Behavioral Family Interventions (BFI) modify factors within the family system to minimize modifiable risk factors and engineer protective factors to produce behavior change (Kazdin, 1991). While several manualized behavioral parenting interventions exist, the Triple P parenting program is one of the most researched and effective programs used internationally, particularly the Level 4 package; …

Regulation Of The Heat Shock Response Via Lysine Acetyltransferase Cbp-1 And In Neurodegenerative Disease In Caenorhabditis Elegans, Lindsey N. Barrett

USF Tampa Graduate Theses and Dissertations

The decline of proteostasis is a hallmark of aging that is, in part, affected by the dysregulation of the heat shock response (HSR), a highly conserved cellular response to proteotoxic stress in the cell. The heat shock transcription factor HSF-1 is well-studied as a key regulator of proteostasis, but mechanisms that could be used to modulate HSF-1 function to enhance proteostasis during aging are largely unknown. In this study, we examined lysine acetyltransferase regulation of the HSR and HSF-1 in C. elegans. We performed an RNA interference screen of lysine acetyltransferases and examined mRNA expression of the heat-shock inducible gene …

A Bathroom Break For Teachers: An Institutional Ethnotheatrical Inquiry, Jonathan M. Coker

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to examine the teacher bathroom dilemma, a term I coined to describe teachers not having adequate access to the bathroom during their workdays. While this issue is widely known by those in the profession, only a handful of articles have been written on this topic. The teacher bathroom dilemma is part of a litany of working conditions that have intensified due to the neoliberal turn in education, forcing teachers to perform precarious actions that endanger their physical and psychological health. This dissertation explored how the teacher bathroom dilemma impacted teachers’ work and personal lives. …

Educational Language Policy: An Examination Of Race And Language In Policy Discourse, Dionne L. Davis

USF Tampa Graduate Theses and Dissertations

Linguistic diversity is an integral thread in the tapestry of America. As such researchers how linguistic differences across ethnoracial groups can be understood as resources rather than problems. The aim of this study was to examine ideologies concerning race/ethnicity and language in the discourse of educational language policies that guide multilingual approaches to education. The design of this study was critical discourse policy analysis, and the framework was a combination of Critical Language and Race Theory, also known as LangCrit (Crump, 2014), and Raciolinguistics (Alim, 2016; Flores and Rosa, 2015). The research questions were: (1) How are ideologies about the …

Color Defined: An Autoethnographic Exploration Of How Race, Trauma, Gun Violence, And Grief Connect For A Black Mother, Kokita Dirton Wilson

USF Tampa Graduate Theses and Dissertations

Black mothers are disproportionately affected by fatal shootings and the need for making meaning and finding purpose remains overlooked as a vital component of building resilience in their grief journey. The purpose of this study was to (a) reflect on being a Black mother of a fatal shooting victim; (b) understand the grief and healing process that follows; (c) connect my experiences to those within the larger Black grief community, and (d) by example, help other grieving mothers navigate through their grief struggles. I used two research questions: 1) How can I learn about my grief process by using personal …

Zooplankton Biodiversity In The Northeast Gulf Of Mexico And On The West Florida Shelf From 2005 - 2014, Megan Ferguson

USF Tampa Graduate Theses and Dissertations

Zooplankton abundance and biodiversity was measured in the northeast Gulf of Mexico (NEGoM) and on the West Florida Shelf. Bongo net samples were collected between May 2005 to September 2009 through the SEAMAP program, and between July 2010 to August 2014 through the C-IMAGE program. Calanoid copepods were the most abundant zooplankton group in most of the samples collected, but ostracods, larvaceans, and chaetognaths were also abundant. Shannon and Inverse Simpson indices were calculated for all zooplankton samples and generally showed similar trends, but only Shannon indices were used for statistical analyses. In the winter and spring there were significant …

Ocean Eddies And Frontal Zones In The Gulf Of Mexico And Straits Of Florida, Yingjun Zhang

USF Tampa Graduate Theses and Dissertations

Ocean eddies and fronts in the Gulf of Mexico (GoM) and the Straits of Florida (SoF) play important roles in ocean physics, biology, and ecology. These two ubiquitous physical features have been studied worldwide for decades, yet many questions remain unanswered or poorly studied for the GoM and SoF. This study aims to improve the understanding of ocean eddies and frontal zones in the GoM and SoF using satellite remote sensing, in situ observations and model outputs, as well as state-of-the-art algorithms, with the following objectives: 1) analyze the three-dimensional (3-D) statistical characteristics and thermohaline structure of mesoscale eddies in …

First-Generation Female Doctoral Students’ Perceptions Of The Doctoral Experience, Nancy Carol Carr

USF Tampa Graduate Theses and Dissertations

The purpose of my study was to understand the perceptions of first-generation female doctoral students (FGFDS) and what factors may impact first-generation female doctoral students’ completion of their doctoral program. As the researcher, I collected data through: (a) interviews, (b) participant generated photographs, (c) the group meeting, and (d) the researcher’s personal reflexive journal. Two research questions guided this exploratory qualitative study: In what ways do first-generation female doctoral students in the College of Education perceive their experiences impact their progress during their doctoral program at a large research university in Central Florida?; and what factors do first-generation female doctoral …

Ethnographic Insight On The Construct Of Blackness: Heritage, ‘Home,’ Community, And Reality In Carver City-Lincoln Gardens, Tampa, Florida, 1928-2021, Lisa Katina Armstrong

USF Tampa Graduate Theses and Dissertations

This study is a community-engaged investigation of the experiences and impacts of Black people living in the segregated space called “Carver City-Lincoln Gardens.” This study aims to advance scholarly and mainstream conversations about one racialized community; it is a significant space because the Lincoln Gardens Area was explicitly designated by the Department of Defense as a residential space for Black veterans after World War II to purchase homes. By exploring this housing arrangement through an anthropological lens, the findings indicate that a mixed-method, collaborative ethnography reveals nuances that might be glossed over when communities are racialized. This study also seeks …
