Hard Hats And Second Chances: A Phenomenological Study Of Employer Support In Construction-Based Reintegration, Christofer M. Pacheco
Hard Hats And Second Chances: A Phenomenological Study Of Employer Support In Construction-Based Reintegration, Christofer M. Pacheco
USF Tampa Graduate Theses and Dissertations
This qualitative phenomenological study examines how formerly incarcerated individuals perceive and experience employer support during workplace reintegration in the construction industry. Although employment is widely recognized as a protective factor against recidivism, post-hire experiences from the perspective of justice-involved employees remain underexplored. Grounded in an interpretivist paradigm and informed by Social Support, Social Learning, and Identity perspectives, the study investigated how structure, self, and environment interact to influence retention, growth, and desistance.
Nineteen interviews were completed with six construction workers in New Mexico who had maintained employment for at least one year following incarceration. Through the use of Seidman’s three-interview …
Considering Context In Latent Models Of Externalizing: Measurement Invariance By Environmental And Systemic Disadvantage In System-Involved Youth, Kendall D. Smith
Considering Context In Latent Models Of Externalizing: Measurement Invariance By Environmental And Systemic Disadvantage In System-Involved Youth, Kendall D. Smith
USF Tampa Graduate Theses and Dissertations
Externalizing forms of psychopathology are said to result from a general liability towards impulsive and disruptive behaviors, including substance use, conduct problems, aggression, and antisocial behavior (Krueger et al., 2021). While the field often focuses on dispositional explanations of externalizing behaviors, there is a notable lack of attention to the contextual factors that contribute to these behaviors, beyond immediate environmental influences. This study uses Ecological Systems Theory (Bronfenbrenner, 2005) as a framework to address such gaps in the context of behavioral indicators of the latent externalizing (EXT) construct, an analysis with implications for understanding racial/ethnic and socioeconomic disparities. The present …
A Bioarchaeological Study Of The Individuals From The Városfalva Burial Mound In Transylvania, Romania (15th-19th Century), Vanessa C. Reeves
A Bioarchaeological Study Of The Individuals From The Városfalva Burial Mound In Transylvania, Romania (15th-19th Century), Vanessa C. Reeves
USF Tampa Graduate Theses and Dissertations
This study explores the lives and deaths of the Szekler people recovered from a burial mound in the Transylvanian village of Városfalva. The Transylvanian plateau is located in present day Romania, and is protected on the east and the south by the Carpathian Mountains. The Szekler people arrived in this area around 1000 CE, and were a nomadic group originating in the Asian Steppes region who later intermarried with various migratory groups as they moved across the Eurasian plains. The Szeklers eventually banded together with the proto-Hungarian Magyar peoples and settled in the Carpathian Basin, the easternmost frontier of the …
When Shame Leads To Silence: Leadership Style Moderates Shame, Silence, And Job Satisfaction, Andrew M. Lyman
When Shame Leads To Silence: Leadership Style Moderates Shame, Silence, And Job Satisfaction, Andrew M. Lyman
USF Tampa Graduate Theses and Dissertations
ABSTRACT Shame is a fundamental self-conscious emotion that shapes behavior and communication in the workplace. This study examined how shame interacts with leadership styles to influence employee silence and job satisfaction. Survey data were collected from 1,500 professionals across diverse industries, and statistical analyses were conducted to test nine hypotheses. Three hypotheses were assessed through direct linear regression while six moderation hypotheses were evaluated using moderated multiple linear regression models to capture leadership style as a contextual influence.
Findings indicated that shame significantly predicted higher levels of silence and lower levels of job satisfaction. Silence was also negatively associated with …
“For Haitian Culture, Being Older [Is] A Blessing”: Perceptions Of Aging, Elderhood, And Dementia In A Haitian Born Sample, Melissa K. Eustache
“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, …
Joint Action (In)Action: A Communicatively Constituted Examination Of Shared Governance, Organizational Sustainability, And The Future Of Liberal Arts In Institutions Of Higher Education, Rebecca R. Todd
USF Tampa Graduate Theses and Dissertations
There are at least two versions of higher education today. One is that universities and curriculum need to be reformed to suit contemporary exigencies, particularly market-driven logics and direct paths to desirable job and career outcomes. The other is the story in this dissertation, namely, that the liberal arts hold value for the creation of new knowledge, critical thinking, and empowerment. With this admittedly one-sided corrective to the dominant narrative of higher education, this abstract and dissertation begin.
In the contemporary landscape of American higher education, the liberal arts are under siege. Once heralded as the cornerstone of democratic citizenship …
Reducing Data Requirements In Polymer Science: Deep Neural Networks For Predicting Surface Tension Of Copolymer Compatibilizers, Md Mushfiqul Islam
Reducing Data Requirements In Polymer Science: Deep Neural Networks For Predicting Surface Tension Of Copolymer Compatibilizers, Md Mushfiqul Islam
USF Tampa Graduate Theses and Dissertations
In polymer chemistry, compatibilization involves adding a substance often a block or graft copolymerto stabilize polymer blends that would otherwise not mix well, leading to rough structures and weak me- chanical properties. Compatibilizers improve miscibility and reduce interfacial tension, which is critical for applications such as mixed-waste polymer recycling. Sequence-controlled polymers offer unique potential by combining the tunable chemistry of synthetic polymers with the precise, function-driven design of biological macromolecules, but unlike proteins, they lack large, evolution-shaped datasets to guide discovery. This research develops a deep learning framework to predict the surface tension of sequence-controlled copolymer compatibilizers across varying concentrations. …
Evaluation Of Functional Communication Training With Sign Mands For Non-Vocal Children With Autism Spectrum Disorder, Hayley Margaret Mcmanus
Evaluation Of Functional Communication Training With Sign Mands For Non-Vocal Children With Autism Spectrum Disorder, Hayley Margaret Mcmanus
USF Tampa Graduate Theses and Dissertations
Children with autism spectrum disorders (ASD) often experience difficulties in both vocal and non-vocal communication, which can lead to problem behavior as a means of expressing needs and wants. Functional communication training (FCT) has been shown to be effective in teaching functional communicative responses (FCRs) and decreasing problem behavior. However, studies on the use of sign language as a communicative response or modality in FCT have been limited, despite its benefits, including feasibility and low response effort, compared to other modalities, such as picture cards and augmentative and alternative communication devices. This study evaluated FCT using sign language mands for …

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 …
Development And Initial Validation Of An Instrument To Measure Teachers’ Socioscientific Issues Instruction Perceptions, Michael Edward Mitchell
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 …
Spatio-Temporal Characterization Of Trace Metals Across The West Florida Shelf And During The Decline Of The North Atlantic Spring Bloom, Delfina Paola Navarro-Estrada
Spatio-Temporal Characterization Of Trace Metals Across The West Florida Shelf And During The Decline Of The North Atlantic Spring Bloom, Delfina Paola Navarro-Estrada
USF Tampa Graduate Theses and Dissertations
Phytoplankton in the marine environment require the trace metals manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), and cadmium (Cd) to catalyze cellular processes driving photosynthesis, including macronutrient (nitrogen, phosphorus, and carbon) acquisition, light harvesting, and protection from oxidative stress. The high biological demand for these elements, coupled with their low concentrations in the ocean, can limit primary production and shape community composition in marine ecosystems, highlighting the need to understand the drivers behind trace metal distributions and their interplay with phytoplankton growth across biogeochemical regimes. This dissertation characterizes the spatial and temporal distributions of dissolved …
Exploring Employee Profiles’ Adaptation To A Return-To-Office Policy: An Eadr Study In Higher Education Administrative Departments, Laura Cecilia Ferraz
Exploring Employee Profiles’ Adaptation To A Return-To-Office Policy: An Eadr Study In Higher Education Administrative Departments, Laura Cecilia Ferraz
USF Tampa Graduate Theses and Dissertations
Flexible work arrangements (FWAs) became a central feature of the post-pandemic workplace, offering autonomy and balance. In higher education administrative departments, hybrid models were widely adopted; however, managers struggled with accountability, equity, and effective communication. At the University of South Florida (USF), a mid-study return-to-office mandate required all employees to resume full-time on-site work, creating an opportunity to examine how employees adapted to the loss of flexibility and whether previously developed employee profiles remained relevant.
This qualitative study employed the Elaborated Action Design Research (eADR) methodology to investigate the experiences of employees and managers across three diagnostic phases. Cycle 1, …

The purpose of this research is to identify potential barriers to equitable employment for Deaf and Hard-of-Hearing (DHH) individuals and to propose effective methods for evaluating and assessing AI and machine learning applications utilized in recruitment and selection processes. Although AI is increasingly embedded in human resource management (HRM), there remains a significant lack of research addressing its use with special populations. In particular, no prior studies have examined how voice recognition software, facial analysis, psychometric testing, and virtual …
Statistical Challenges And Simulation Results For Pilot Clinical Trials, Weiliang Cen
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: …

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

Middle School Counselors' Perceptions Of Meeting Career Counseling Needs Of Middle School Students, Mario Oscar Garcia
USF Tampa Graduate Theses and Dissertations
This dissertation examined middle school counselors' perceptions of their effectiveness in delivering career counseling to students. Middle school is a pivotal time for career exploration and planning, yet disparities in guidance persist, particularly for students not on a traditional college pathway. Guided by the American School Counselor Association (ASCA) National Model, this study employed a survey method. An online survey developed by the researcher assessed counselors' time allocation across academic, career, social-emotional, and duties unrelated to their essential school counseling roles. Additionally, the survey inquired about counselors’ perceived effectiveness in meeting the career needs of diverse student populations (advanced academic, …
Geographic Patterns Of Educational Achievement: A Methodological Case Study Of Regression Modeling Approaches, Leokadia Lipien
Geographic Patterns Of Educational Achievement: A Methodological Case Study Of Regression Modeling Approaches, Leokadia Lipien
USF Tampa Graduate Theses and Dissertations
This methodological case study introduces a novel approach to investigate the impact of student, teacher, and geographic factors on the academic achievement of virtual school students in Florida. Traditional linear regression models, and even multilevel models, often overlook spatial dependencies, which can lead to biased estimates and incomplete inferences. This research addresses this limitation by comparing a cross-classified multilevel model (CCMM) with a novel cross-classified spatial model (CCSM) that incorporates coefficients from geographically weighted regression (GWR). Utilizing secondary data from a statewide virtual school, including student demographics, teacher characteristics, and standardized test scores, along with U.S. Census Bureau data, the …
Surveying Secondary Ela Teachers’ Engagement With Ai-Powered Tools For Classroom Assessment, Mona Alrashidi
Surveying Secondary Ela Teachers’ Engagement With Ai-Powered Tools For Classroom Assessment, Mona Alrashidi
USF Tampa Graduate Theses and Dissertations
The integration of Artificial Intelligence (AI) presents profound challenges andpossibilities for educational assessment, particularly in English Language Arts (ELA), where AI- powered tools can generate the very linguistic products traditionally used as evidence of student learning. While scholarship has primarily explored theoretical frameworks and broad perceptions, a critical gap remains in understanding how secondary ELA teachers navigate and report AI integration within formative assessment workflows. This understanding is essential: formative assessment has been recommended as a strategy to mitigate AI-related challenges by prioritizing learning processes over products. Yet empirical evidence of teachers’ practices remains limited.
This exploratory study surveyed 102 …
Mathematics And Growth Mindset: A Systematic Review And Meta-Analysis Of Interventions At The Post-Secondary Level, Sean E. Murphy
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
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 …
From Past Pain To Present Unity The Role Of Trauma In Shaping Collective Identity Within Refugee Communities, Shahd Alasaly
From Past Pain To Present Unity The Role Of Trauma In Shaping Collective Identity Within Refugee Communities, Shahd Alasaly
USF Tampa Graduate Theses and Dissertations
In this dissertation I explore the social dimensions of trauma and resilience among Syrian refugees resettled in the United States. Drawing on in-depth interviews and focus group data collected at a resettlement center in Tampa, Florida, I aim to understand how displacement reshapes identity, disrupts traditional gender roles, changes social bonds, and how healing occurs within one’s community. I frame my work within Social Identity Theory, Identity Theory, and the sociology of trauma. My research highlights the gendered expressions of trauma, the transformation of masculinity under forced migration, and the role of spirituality in community healing.
This project includes three …
A Multi-Faceted Study Of Antibiotic-Resistant, Opportunistic Pathogens In Wastewater And Environmental Water, Jeanette Calarco
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 …

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 …

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
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
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 …

Traditional methods for reliability assessment and threat detection often rely on model-based approaches that struggle to adapt to the complexity and dynamic nature of modern smart grids. These limitations necessitate novel data-driven …
The Relationship Between Physical Activity And Cognitive Performance In African American Older Adults, Rio S. Tate
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 …
