“For Haitian Culture, Being Older [Is] A Blessing”: Perceptions Of Aging, Elderhood, And Dementia In A Haitian Born Sample, Melissa K. Eustache

USF Tampa Graduate Theses and Dissertations

This thesis investigates how first-generation Haitian immigrants in the United States understand and interpret dementia within the intersecting contexts of culture, migration, and biomedicine. While dementia is constructed as a pathological “loss of self” and a public health epidemic, in American biomedical and popular discourse, this study examines how Haitian-born individuals—socialized within a non-Western cultural and spiritual framework—make sense of cognitive decline and impairment in ways that diverge from Western biomedical narratives. Guided by theoretical orientations from medical anthropology, including Mark Nichter’s idioms of distress, Margaret Lock’s local biologies, and neuroanthropology, this research explores how cultural models of illness, aging, …

Role Conflict And Burnout: How Can Employed Graduate Students Thrive, Not Just Survive?, Eric M. Douthirt

USF Tampa Graduate Theses and Dissertations

This dissertation investigates several of the multifaceted challenges faced by employed graduate students, a growing demographic within U.S. higher education. Against a backdrop of intensifying technological change, evolving labor market dynamics, and increased educational attainment, these individuals encounter pronounced school-work-family conflict (SWFC), resulting in a heightened risk for personal burnout (PB).

Building upon the job demands-resources theory, this research explores whether school-work facilitation (SWF) and student emotional engagement (EE) might attenuate the deleterious relationship between school-work-family conflict (SWFC) and personal burnout (PB), with gender and number of children included as controls.

Data from 489 participants, collected via a single cross-sectional …

The Characterization Of Sleep Quality In Pediatric Cancer Survivors With Overweight/Obesity, Erin M. Brennan

USF Tampa Graduate Theses and Dissertations

Advances in cancer treatment have improved survival rates among pediatric cancer survivors (PCS), shifting the focus toward long-term quality of life. Despite this progress, PCS remain at elevated risks of chronic health issues, including disrupted sleep and obesity. The purpose of this study was to characterize the sleep of PCS with overweight/obesity and to identify predictors of sleep quality. Guided by Merz and Tomfohr-Madsen’s (2018) conceptual framework for sleep disruption in children impacted by cancer, this secondary analysis of data examined disease parameters, family and environmental factors, and physical activity as potential predictors of sleep quality. Participants were enrolled between …

Statistical Challenges And Simulation Results For Pilot Clinical Trials, Weiliang Cen

USF Tampa Graduate Theses and Dissertations

Background: The effect size estimated from a pilot trial is often an inaccurate reflection of the true effect size observed in a large trial, leading to either underestimation or overestimation. Published data suggest that effect sizes from large trials are typically smaller than those reported in their corresponding pilot trials. To address this discrepancy, conservative or discount adjustment methods are widely recommended to modify pilot trial effect sizes when calculating sample sizes, thereby maintaining adequate statistical power. This study aims to assess effect sizes from both pilot and large trials and to evaluate the performance of existing adjustment methods.

Methods: …

Development And Initial Validation Of An Instrument To Measure Teachers’ Socioscientific Issues Instruction Perceptions, Michael Edward Mitchell

USF Tampa Graduate Theses and Dissertations

Little is known about how high school science teachers perceive Socioscientific Issues (SSI) on a broad scale, including what factors shape their views of a pedagogical shift to adopt SSI. To address this critical gap, I constructed the Teachers’ Socioscientific Issues (SSI) Perceptions Survey (TSPS), the first instrument specifically designed and initially validated to measure teacher perceptions of SSI integration. This study presents the development and validation of the TSPS, offering robust evidence for its reliability, fairness, and construct validity.

Survey development adhered to gold-standard psychometric protocols (Bandalos, 2018; Crocker & Algina, 1986; DeVellis, 2012; McCoach et al., 2013) and …

Investigating Whether Giving Or Receiving Support Impacts Caregivers Who Were Maltreated Or Not Maltreated Differently, Tara D. Matta-Singh

USF Tampa Graduate Theses and Dissertations

Caregivers can experience higher levels of stress, anxiety and depression compared to non-caregivers. However, a growing body of literature is beginning to show that while caregiving may be stressful, there may also be benefits to the caregiver, such as feeling closer to the care recipient, a sense of purpose or personal growth. Further, research now demonstrates that giving support to others can be more beneficial than receiving support from others in terms of mental health and even mortality. While these are important advances in the literature, understanding the impacts of giving and receiving support on individuals who were maltreated by …

Mathematics And Growth Mindset: A Systematic Review And Meta-Analysis Of Interventions At The Post-Secondary Level, Sean E. Murphy

USF Tampa Graduate Theses and Dissertations

Growth mindset interventions have been implemented in academic settings for over three decades (C. S. Dweck et al., 1995a). One academic field where growth mindset may be most needed is mathematics, as it is not unusual for a student to claim, “I’m not a math person.” Notably, no meta-analysis of mindset interventions in post-secondary mathematics classrooms existed prior to the current study. To close this gap in the literature, the present study included a systematic review and meta-analysis, drawing on two search methods: Boolean and snowballing. The results from both methods were screened using inclusion/exclusion criteria. Snowballing search was hypothesized …

Literacies Of Resistance: How Florida Teachers Story Policy Navigation And Response, Katharine E. Hull

USF Tampa Graduate Theses and Dissertations

Teachers are inundated with education legislation and the policy texts and discourses that surround them. Over nine months beginning in March 2024, I collaborated with three Florida P-12 teachers to explore their literacy practices and stories as they engaged with policy in a state that has recently passed an astounding amount of education legislation. This study explored how (1) teachers story the current policy context and their roles within it; (2) teachers use literacy practices to understand and respond to P/policies that impact their labor/working lives; and (3) teachers’ literate identities, agency, and collectivity intersect and shape one another. Guided …

Leveraging Dna Methylation Profiling And Microrna Sequencing To Characterize The Epigenomic Landscape Of Major Depressive Disorder Disease Trajectory, Jan Dahrendorff

USF Tampa Graduate Theses and Dissertations

Major depressive disorder (MDD) is a common and debilitating mental disorder associated with a significant disease burden and economic cost. Despite ample evidence documenting the efficacy of a diverse array of established MDD therapies, a large proportion of patients are inadequately responsive to initial treatment attempts, with first-line treatments leading to remission in only ~30% of the patients. Importantly, about a third of patients even fail to achieve symptom improvement after two or more antidepressant trials, resulting in what is commonly defined as treatment-resistant depression (TRD). The ability to identify which treatments are most likely to elicit a positive response …

A Multi-Faceted Study Of Antibiotic-Resistant, Opportunistic Pathogens In Wastewater And Environmental Water, Jeanette Calarco

USF Tampa Graduate Theses and Dissertations

More than 2.8 million infections due to antibiotic-resistant bacteria occur annually in the United States, and more than 35,000 people die as a result. Domestic wastewater (sewage), which contains antibiotic-resistant bacteria and antibiotic resistance genes, is collected at treatment plants for removal of contaminants, e.g. pathogenic microorganisms and nutrients. While wastewater treatment is designed to remove antibiotic-resistant bacteria and other microorganisms through treatment and disinfection, some bacteria may escape treatment. Treated wastewater effluent is generally discharged into surface waters; however, some fraction of the effluent may be used as recycled water. Compromised wastewater collection infrastructure and sewage spills can disseminate …

The Barriers And Facilitators Of Maternal Influenza Vaccination, Rashida Karida Jones

USF Tampa Graduate Theses and Dissertations

Influenza remains a leading cause of morbidity and mortality in the United States, with Black individuals disproportionately affected. Pregnant women are particularly vulnerable due to their modulated immune state, placing them at increased risk of complications, hospitalization, and intensive care admission. Despite strong evidence supporting the safety and efficacy of maternal seasonal influenza vaccination (SIV), uptake remains suboptimal. This study employed a multi-method design to identify barriers and facilitators of maternal SIV uptake, with a particular focus on racial disparities.

Quantitative analyses utilized the Florida Pregnancy Risk Assessment Monitoring System (FL PRAMS) dataset from the years 2018–2022. In the fully …

Breaking The Cycle: A Teacher And Mother’S Examination Of Multi-Tiered Systems Of Support, Jessica Hinton

USF Tampa Graduate Theses and Dissertations

The 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA) included Response to Intervention (RTI) as an option for determining eligibility for learning disabilities. However, there is no required structure to follow for RTI implementation. This lack of guidance leads to a lack of clarity in implementation at district and site levels. Many states use RTI as the primary indicator of whether a student needs special education services for a learning disability. RTI is a model for delivery of Multi-Tiered Systems of Support (MTSS). The terms RTI and MTSS are often used interchangeably. For clarity, I use MTSS-RTI to …

The Relationship Between Perceived And Actual Knowledge Of Multi-Tiered Systems Of Support/Response To Intervention (Mtss/Rti) In Middle School Principals In Florida, Susan L. Sanger-Miller

USF Tampa Graduate Theses and Dissertations

Principals play a crucial role in implementing MTSS/RtI (Multi-Tiered Systems of Support/Response to Intervention), yet little is known about their understanding of the RtI component. This quantitative survey examined Florida middle school principals’ actual and perceived knowledge of MTSS/RtI, as well as how training and demographic factors—such as special education certification, education level, Title I status, administrative experience during rollout years (2006–2010), district training hours, and college coursework—relate to that knowledge. Data from 54 principals were collected through perception scales, training background, and knowledge-based questions. Results showed principals rated their perceived knowledge higher than their actual knowledge, with a moderate …

Enhancing Nitrogen Removal In High Permeability Bioretention Media: The Combined Role Of Biochar, Wood Chips And Hydraulic Design, Joshelyn Guimaray

USF Tampa Graduate Theses and Dissertations

Urban stormwater runoff can transport high nutrient loads to receiving waters, leading toeutrophication, harmful algal blooms, and the formation of hypoxic zones. Bioretention systems are a form of green infrastructure designed to mitigate these impacts, but their application in dense, ultra-urban environments is often limited by large land area requirements. This has led to the adoption of high permeability media (HPM) to accommodate higher hydraulic loading rates (HLRs) and reduce the system footprint. However, conventional HPM systems often show inconsistent removal of dissolved nitrogen species due to short hydraulic retention times (HRTs), a lack of organic carbon, and insufficient anoxic …

Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache

USF Tampa Graduate Theses and Dissertations

Coral reef ecosystems are declining globally from numerous stressors, including localized pollution, disease, and marine heatwaves induced by climate change. To preserve these ecosystems, it is critical to identify corals that can withstand stressors—primarily future marine heatwaves—and prioritize them for coral restoration efforts until these stressors are mitigated. Coral responses to thermal stress can be influenced by several partners, including mutualistic microalgae and a vast prokaryotic community. Here, I use advanced molecular techniques to examine which partners (coral host, algal symbiont, and microbial communities) are associated with coral health, how they contribute to holobiont physiology, and their potential to increase …

The Relationship Between Physical Activity And Cognitive Performance In African American Older Adults, Rio S. Tate

USF Tampa Graduate Theses and Dissertations

The number of older adults in the United States is expected to increase in the years to come. As we age, cognitive performance is noted to decline. African American older adults are more likely than non-Hispanic Whites to experience cognitive impairment and dementia. It is known that physical activity is a modifiable risk factor for dementia. It is not known the extent to which physical activity engagement is related to cognitive performance in African American older adults, and which variables, if any, moderate this association. To answer this question, the authors examined the association between three intensities of physical activity …

The Ruling Relations Of Care: An Institutional Ethnography Of High-Risk Prenatal Care Experiences, Nicole L. Harris

USF Tampa Graduate Theses and Dissertations

Disrespect during pregnancy, labor, and delivery is common in the United States. The Centers for Disease Control and Prevention has estimated that approximately one in five women overall, and over 30% of Black women, report being ignored, dismissed, or verbally mistreated during their care. Public health efforts have primarily focused on individual-level interventions to improve patient-provider communication or reduce provider bias; however, these strategies have been critiqued for their limited scope and effectiveness in shifting outcomes. Instead, researchers and advocates have called for an examination of the structures that shape clinical encounters, including policies, protocols, workflows, and organizational culture. This …

The Role Of Peer Networks In Elementary Teacher Preparation Programs, Bayan Alnaim

USF Tampa Graduate Theses and Dissertations

This research provided insight into how peer networks related to the professional learning of TC as they moved through an elementary teacher preparation program. These formal and informal peer networks helped nurture collegiality among TCs to aid learning and provide emotional support, which allowed an edge toward forming an identity. This study examined the particular role of teacher networks in TCs’ learning (Al Sultan, 2021; Anderson et al., 2022). The study applied Social Constructivism and Communities of Practice frameworks to analyze the influence of peer networks on the development of teaching skills and professional identities. Data from TCs participating in …

Dissecting The Intrinsic And Extrinsic Regulators Of Prostate Cancer Dormancy In The Bone Microenvironment, Mostafa M. Nasr

USF Tampa Graduate Theses and Dissertations

Metastatic disease is the primary driver of cancer-related mortality. In prostate cancer (PCa), patient survival decreases dramatically once the disease spreads to distant organs, with over 80% of metastases occurring in the bone. This dissemination is often followed by a clinically silent period of tumor dormancy that can last for years, creating a critical reservoir of cells poised for lethal relapse. A significant barrier to understanding and targeting this dormant phase has been the lack of robust experimental models. This thesis first addresses this challenge by establishing a novel stress-induced model of PCa dormancy, validated across multiple murine and human …

Rattlesnakes And Enlightenment Science: An Unlikely Epistemology Of Early American Herpetology, Sahir Hismiogullari

USF Tampa Graduate Theses and Dissertations

This study examines the hybrid epistemologies developed by early American naturalists, such as Hans Sloane, Pehr Kalm, John and William Bartram, and Benjamin Smith Barton that blended empirical observation, spiritual frameworks, and Indigenous ecological knowledge. These figures, implicitly or explicitly challenging the dominant mechanistic and reductionist models of Enlightenment science, pioneered a more holistic ecological thinking, even as they operated within colonial power structures.

Through historical and textual analysis based on letters, natural histories, and other written sources, the study reveals how these naturalists synthesized multiple ways of knowing, particularly in their encounters with New World peoples and environments. Within …

It is essential for counselors to practice self-awareness so that they may connect effectively with clients, make ethical decisions, and enhance their professional competence. Self-awareness is best identified as a transformative and reflective integration process. While traditional methods like journaling and supervision are commonly studied, the use of sand tray therapy as an expressive art intervention has received limited attention. This review synthesizes existing literature on self-awareness and sandtray expressive art interventions in counselor education, …

Community, Autonomy, Irony: Lessons From Historic Rosenwald Schools, Ronald B. Matus

USF Tampa Graduate Theses and Dissertations

Growing evidence suggests the Rosenwald schools of the American South, which anchored thousands of Black communities for a half century before desegregation, boosted academic outcomes for generations of Black students and helped fuel the civil rights movement. The research literature, however, is thin on what specifically made these schools successful. My research attempts to narrow the gaps by asking the Rosenwald alums themselves. Through semi-structured interviews, 10 alums in Florida identify defining features of their schools, including seamless community connections; a culture of high expectations for academic achievement and character development; and especially caring and committed teachers. The alums’ insights …

“The Best Laid Plans”: Evaluating How Housing Expectations Impact Prison Reentry, Vittoria A. Gonzalez

USF Tampa Graduate Theses and Dissertations

This study assesses the expectations of housing stability pre-release and evaluates how closely these expectations align with actual housing outcomes. Additionally, this study examines how the alignment between pre-release housing expectations influences recidivism. The aim is to understand how individuals’ perceptions of their housing plans prior to release affect their reentry experiences and to offer insights that may inform policy and program design. Using data collected pre- and post- release within a prison reentry program from 115 individuals, results indicate that higher overall housing concern is associated with slightly higher odds of recidivism, and mismatches between expected and actualized housing …

Seagrass beds provide important services in many coastal ecosystems. They provide habitat and food for a wide range of marine species, stabilize sediments, and prevent coastal erosion. These services support local fisheries and tourism-driven economies. Yet, seagrass ecosystems are threatened by changes in water quality, sedimentation, and other stressors. This study investigated the interannual variability in seagrass extent in Salt River Bay, United States Virgin Islands (USVI), from 2018 to 2024. The goals were to better understand temporal dynamics in seagrass extent and evaluate the influence of turbidity as a driver of seagrass health and distribution. The overarching research question …

Exploring The Behaviors Of Women Who Are Mentally Thriving With Autoimmune Disease: A Mixed Methods Approach, Emilie Ann Ellenberg

USF Tampa Graduate Theses and Dissertations

Autoimmune diseases encompass a variety of conditions that impact millions of Americans, with a higher prevalence among women than men. These diseases involve immune system dysregulation, leading to tissue damage and dysfunction. Despite progress in understanding their underlying mechanisms, important aspects remain inadequately understood, such as the relationships among immune dysregulation, medical outcomes, and psychiatric comorbidities. Preliminary qualitative research indicates that perceived diagnostic invalidation leads to the mental health needs among women with autoimmune diseases often being unmet, and behavioral health help-seeking behaviors being reduced. Although perceived diagnostic invalidation can lead to increased mental health symptomology and decreased help-seeking behaviors, …
