A System Dynamics Perspective Of User Adaptation: The Case Of Exoskeleton Technology, Enzo Novi Migliano

USF Tampa Graduate Theses and Dissertations

Technology implementation is a common occurrence in organizations to which workers must adapt. Although research on workers' technology acceptance is widely spread, research on the workers' technology adaptation process is less represented in the literature. The discrepancy in the literature permeates research on new technologies currently being implemented in organizations, such as occupational exoskeletons. As in other technologies, the variance research perspective dominates the literature on exoskeleton implementations. The current thesis aims to foster process research by formalizing the coping model of user adaptation (Beaudry & Pinsonneault, 2005) and exploring research questions regarding workers' adaptation to general technology and exoskeletons. …

From Cardiovascular Safety Assessment To Peptide Hemolytic Activity Prediction: Integrative Computational Analyses For Drug Evaluation And Discovery, Xinran Zhu

USF Tampa Graduate Theses and Dissertations

This thesis applied integrative computational approaches to two major areas of drug evaluation and discovery: cardiovascular safety assessment and peptide hemolytic activity prediction. First, pharmacovigilance data from the FDA Adverse Event Reporting System (FAERS), electronic health records (EHRs) from TriNetX, and transcriptomic analyses were combined to evaluate anesthetic-associated cardiac rhythm adverse drug events. Among propofol, ketamine, dexmedetomidine, and midazolam, dexmedetomidine showed the strongest association with bradycardia across both FAERS and propensity score-matched EHR analyses. Stratified analyses further suggested substantially higher bradycardia prevalence among older patients and a modestly increased risk among male patients. Drug-drug interaction analyses identified risperidone and albuterol …

House Sparrows Reveal Hidden Reservoirs Of Antimicrobial Resistance, Nathan Dowling

USF Tampa Graduate Theses and Dissertations

Antimicrobial resistance (AMR) is a growing global health threat, yet surveillance for antimicrobial resistance genes (ARGs) remains concentrated in clinical and livestock systems, leaving environmental and wildlife reservoirs comparatively understudied. The objective of this study was to evaluate whether one synanthropic bird species integrates landscape-level antimicrobial resistance pressures across socioeconomic gradients and to identify the predictors most strongly associated with cross-national variation in ARG prevalence. We examined ARG occurrence in the globally distributed house sparrow (Passer domesticus), sampling 205 individuals across eight countries spanning large gradients in economic development, antimicrobial use, and governance structure. Using targeted molecular screening of gastrointestinal …

Using The Good Behavior Game To Decrease Challenging Behavior In Children With Autism Spectrum Disorder, Andrea M. Babb

USF Tampa Graduate Theses and Dissertations

Challenging behavior in school settings can negatively impact academic engagement, social relationships, and access to instruction. Previous research has shown that the Good Behavior Game (GBG) can improve academic performance and decrease challenging behavior. Generally, to play the GBG, the teacher establishes a set of rules (e.g., “remain seated during the lecture”) that the students should follow and divides the class into two teams. When a student on either team breaks a rule, the teacher gives that team a tally or hatch mark. The team with the fewest tallies at the end of the game wins a prize. The current …

Evaluating The Effects Of Response Cards On Active Student Responding And On-Task Behavior With Elementary Students Diagnosed With Autism And Other Disabilties, Joshua N. Alvarado

USF Tampa Graduate Theses and Dissertations

One of the most prominent difficulties that students diagnosed with autism spectrum disorder (ASD) face in their education is consistently engaging in on-task behavior and active participation during whole-class group instruction. The use of response cards is one method that has been demonstrated to have beneficial effects for increasing on-task behavior and active participation for students with disabilities. However, there is limited research on effects with students diagnosed with ASD, particularly elementary students. The purpose of this study was to evaluate the effects of two response card types to increase active student responding, on-task behavior and correct responding for elementary …

When “Mild” Isn’T Minor: Return-To-Work Challenges In Post-Stroke Mild Aphasia, Maya Berro

USF Tampa Graduate Theses and Dissertations

Return-to-work (RTW) is an important aspect of social participation and quality of life following stroke. However, limited research has explored the experiences of individuals with mild aphasia in the RTW process. This purpose of this qualitative study was to explore how individuals with post-stroke mild aphasia perceive their ability to RTW and identify factors that influence this process. Ten adults with mild or very mild aphasia participated in individual semi- structured interviews conducted via Microsoft Teams. Interview transcripts were analyzed using inductive thematic analysis. Three major themes emerged: (1) Barriers to RTW, (2) Facilitators to RTW, and (3) Perceptions of …

Exploring Culturally Responsive Leadership Practices Among Female Leaders In Title I Schools: Strategies For Enhancing Student Success, Tara K. Indar

USF Tampa Graduate Theses and Dissertations

The academic achievement gap between White students and diverse student populations remains a persistent and prominent disparity in schools across the United States. While this issue affects schools nationwide, it is particularly significant in Title I schools, where many students from diverse, lower-socioeconomic-status backgrounds are served. Although a substantial body of literature examines this gap and highlights the positive impact of culturally responsive leadership, there remains a limited understanding of which specific practices are most effective in improving students’ academic outcomes. This study explores the perceptions of female school leaders in Title I schools regarding the strategies they believe contribute …

Modeling And Mitigating Stale Hardcoded Secrets In Version Control History, Katarina Valentine Capalbo

USF Tampa Graduate Theses and Dissertations

Hardcoded secret vulnerabilities remain a growing and persistent problem that can be difficult to mitigate once exposed. While there has been significant research and advancements in identifying and preventing hardcoded secrets, less attention has been given to understanding the risks of leaving these secrets behind in version control history, as well as analyzing the sanitization of hardcoded secrets. These challenges present a growing gap between the risk and ability to mitigate and sanitize existing secret exposures. This thesis begins to address this gap by formalizing a threat model for hardcoded secrets that persist in Git version control history after the …

Testing The Impact Of Sexual Minority Stress On Endorsement Of Prospective Behaviors Related To Borderline Personality Disorder Among Lesbian, Gay, Bisexual, And Queer Adults, E. Elisa Carsten

USF Tampa Graduate Theses and Dissertations

Sexual minority individuals face increased risk for numerous forms of psychopathology compared to heterosexual individuals, including borderline personality disorder (BPD). Previous investigation into the causes of these mental health disparities highlights several sexual minority-specific factors that may render sexual minority individuals uniquely vulnerable to meeting criteria for a BPD diagnosis, including chronic exposure to minority stressors, such as sexual orientation-based discrimination and stigmatizing beliefs. Some scholars have argued that the relevance of these minority-specific stressful experiences hampers the utility of a BPD diagnosis among members of this historically marginalized population. The present study experimentally tested the influence of minority stressors …

USF Tampa Graduate Theses and Dissertations

Providing nursey habitat, regulating nutrients, stabilizing shorelines, increasing biological diversity, improving water quality, and creating three-dimensional environments are some of the ecosystem services of oyster reefs. Oyster reefs are threatened by overharvesting, changes in water quality, pollution, and disease. The Eastern oyster, Crassostrea virginica, is the primary oyster species along Florida’s Gulf coast. This study aimed to evaluate the relationship between multiple parameters on artificial reefs and how they influence the health of these reefs. Here, young (less than five years old) artificial oyster reefs were monitored for one year across three sites in Tampa Bay, FL: Lassing Park (LAS), …

Evaluating Some Effects Of Exposure To Prompt Topographies On Intraverbal Acquisition Rates And Choice For Prompt Topographies, Isabella Zaccor

USF Tampa Graduate Theses and Dissertations

People with developmental disabilities often have communication deficits, which create challenges with functioning in everyday life, making it more difficult for these people to foster meaningful relationships and live an independent life. People with developmental disabilities may need a more structured approach to learning important skills such as communication and social skills, such as learning with prompt topographies. By replicating Roncati et al. 2019, which evaluated exposure to prompt topographies and the effect on acquisition rates, we evaluated an adapted alternating treatments design within a multiple baseline across participants design to examine whether exposure to a specific prompt topography changed …

Discourse Production And Its Relationship To Cognition In Mild Aphasia, Marcy D. Edwards

USF Tampa Graduate Theses and Dissertations

Objective:Standardized assessments such as the Western Aphasia Battery-Revised do not reliably detect subtle language impairments in mild aphasia (Dalton & Richardson, 2015). Discourse tasks may provide a more sensitive measure of impairment. Although discourse tasks differ in cognitive demands (Kim & Kintz, 2024), variation in discourse performance across tasks and the influence of cognition remains unclear. Therefore, this study examined (1) whether discourse performance differs across different discourse elicitation tasks, and (2) the extent to which cognition influences discourse performance in individuals with mild aphasia.

Participants & Methods: Fifteen participants with mild aphasia participated (mean age = 62.7 years). Discourse …

Historical aerial photos since the 1940s were collected and analyzed to understand the last closure of Midnight Pass, and to gain knowledge on the future of the newly reopened inlet. Time-series topography and bathymetry survey of the beach-inlet system were conducted bimonthly to quarterly for the first year and a half after the reopening, with the goals of quantifying the morphologic changes and understanding …

Caregiver-Implemented Functional Analysis Of Moderate-To-Vigorous Physical Activity Of Children, Rachel B. Riccardo

USF Tampa Graduate Theses and Dissertations

Most children do not currently meet the 60 min per day recommendation for moderate-to-vigorous physical activity (MVPA), which could lead to problematic health outcomes. Researchers have used behavioral assessments (i.e., functional analysis [FA]) to identify the maintaining variables (e.g., attention, interactive play) that produce elevated levels of MVPA. The purpose of this study was to evaluate the extent to which a caregiver-implemented FA can identify the function of their child’s MVPA. All three participants engaged in elevated levels of MVPA when adult interaction and attention were delivered contingently. The results of this study showed that caregivers implemented FAs of MVPA …

Evaluating Generalization-Enhanced Behavioral Skills Training To Teach Firearm Safety Skills To Children With Autism, Victoria Alvarez

USF Tampa Graduate Theses and Dissertations

Due to the large number of firearm-related incidents and the high percentage of households that own firearms in the United States, it is crucial that children learn firearm safety skills. Although previous research has evaluated various procedures for teaching firearm safety skills to typically developing children, there is a limited amount of research evaluating these interventions for children with autism spectrum disorder (ASD). The current study evaluated the effectiveness of a generalization-enhanced behavioral skills training (BST) procedure, which included varied training settings and tangible reinforcers, to teach firearm safety skills to children with ASD. We evaluated generalization-enhanced BST and in …

Listener Factors In Integrating Syntax And Plausibility In Sentences Produced With Versus Without Stuttering, Gabriella L. Burgess Hayes

USF Tampa Graduate Theses and Dissertations

Purpose: Development of communication-focused therapy for people who stutter requires better understanding of how stuttering impacts oral comprehension. One aim was to investigate how stuttering impacts listeners’ ability to integrate syntax and world knowledge (plausibility) in sentence processing. A second aim was to investigate how listener factors predict ability to integrate information in sentences with stuttering.

Methods: 224 adults heard 24 experimental sentences interspersed with 24 fillers. Experimental sentences included six plausible double-object dative (DO) constructions, six plausible prepositional dative (PD) constructions, six implausible DO constructions, and six implausible PD constructions. Implausible constructions served as analogues of communication breakdowns. Half …

Measures Of Linguistic Complexity And Vocabulary Diversity As Indicators Of Oral Language Production Growth Of 4th Grade Spanish-Speaking Els, Carla T. Zayas-Santiago

USF Tampa Graduate Theses and Dissertations

As fourth-grade students transition from learning to read to reading to learn, their ability to use language for academic purposes becomes increasingly important, particularly for Spanish-speaking English Learners (ELs). However, students often have limited opportunities to produce extended oral language during instruction. Students’ oral language production reflects both structural aspects of language use, captured through measures of linguistic complexity, and lexical aspects of language use, captured through measures of vocabulary diversity. Although prior studies have examined transcript-derived measures of oral language production, limited research has examined how these measures predict English proficiency, capture growth over time, and respond to different …

The Architecture Of Chemical Understanding: How Representation Selection, Ordering, And Feature Salience Shape Students' Conceptions In Chemistry, Isaiah Nelsen

USF Tampa Graduate Theses and Dissertations

Chemical representations play a central role in how students learn and reason aboutchemistry. While representations are routinely used in chemistry classrooms, students often struggle to extract relevant information, connect representations to underlying chemical principles, and apply this information to problem-solving. This dissertation investigates the role of representations in supporting students’ conceptual understanding and reasoning across general and organic chemistry through three qualitative studies.

The first study in this work explores how variation in chemical representation influences how students understand foundational chemistry principles. This study sought to characterize how second semester general chemistry students approach dipole–dipole interaction tasks with four distinct …

Unquaint Pigs’ Stakeholder Perspectives On Wild Swine In Central Western Florida, Tyler Koerner

USF Tampa Graduate Theses and Dissertations

The Anthropocene presents important questions for how to address the continuous transferal of new species into new spaces and the cascading impacts of environmental transformations. Novel ecosystems present one such outline for conservation that acknowledges the modification of historic ecosystems and the social entanglements that arrive with new species. I argue that novel ecosystems can benefit from further anthropological integrations that aid in describing the entanglements of introduced species and the pursuit of best managerial outcomes. For wild swine in Florida, the adoption of a novel approach is especially relevant because of entanglements with historic and modern Floridian stakeholders and …

The Heterogeneous Response Of Astrocytes In Different Brain Regions Under Metabolic Stress, Pawan Kumar Thapaliya

USF Tampa Graduate Theses and Dissertations

Astrocytes play a central role in maintaining ionic homeostasis, neurotransmitter clearance, and brain en-ergy metabolism. Their excitability, reflected in activity-evoked intracellular sodium (Na+, [Na+]i) and calcium (Ca2+,[Ca+]i) dynamics, is increasingly recognized as a critical determinant of neuronal function and vulnerability, particularly under metabolic stress. Despite their importance, the mechanisms underlying astrocytic ionic signaling and its regional heterogeneity remain incompletely understood. In this thesis, I developed detailed computational and biophysical models to investigate astrocytic Na+ and Ca2+ dynamics, their bioenergetic consequences, and the roles of key ion transporters under physiological and metabolically stressed conditions, validating the models against experi- mental data. …

Motivating Lung Cancer Screening Uptake: An Experimental Test Of Didactic Versus Narrative Messages For Lung Cancer Screening Among Individuals Who Currently Smoke Or Formerly Smoked, Honor M. Woodward

USF Tampa Graduate Theses and Dissertations

Lung cancer is the number one cause of cancer-related death in the United States and worldwide. Lung cancer screening with low-dose computed tomography (LDCT) has been associated with a 20% reduction in lung cancer-related mortality. Despite the obvious benefits of lung cancer screening with LDCT, screening is heavily underutilized compared to other cancer screening tests. Thus, it is critically important to develop strategies that help motivate screening uptake among eligible individuals. This study explored the effectiveness of narrative messages for motivating lung cancer screening uptake among individuals eligible for lung cancer screening who currently smoke or formerly smoked. Drawing from …

By relaxing traditional constraints on where and how people work, remote job opportunities (RJOs) have the potential to alter both geographic mobility and labor market inequality. The first chapter focuses on how remote work affects internal migration patterns, while the second chapter examines its implications for gender differences in employment and wages.

Chapter 1 examines how the expansion of remote job opportunities shapes internal migration patterns in the United States. The expansion of remote job opportunities has decoupled employment from …

The Materiality Of Religious Syncretism And Co-Production In The Catacombs Of Sicily And Malta: Novel Techniques For The Interpretation And Dissemination Of Legacy Data, Madeleine A. Kraft

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the lengthy history of the investigations into the catacombs of Sicily and Malta. These investigations, in some cases, began as early as the 17th century. They have maintained the intrigue of archaeologists beginning in the late 19th century. In doing so, these spaces have amassed truly remarkable amounts of data and of interpretations of that data. This legacy data has proved simultaneously a barrier and an entrance to understanding these complexes. While they are valuable for descriptions of the spaces prior to mutilations and interventions as well as descriptions of evidence no longer extant due to a …

The Philosopher Of The Future: What Is It To Us That Herr Nietzsche Has Become Well Again?, Erli Mertika

USF Tampa Graduate Theses and Dissertations

This dissertation argues that Nietzsche thought he was a genuine philosopher despite seeming at times to suggest that he was not. I arrive at this conclusion by comparing his thoughts on genuine philosophers with his thoughts about himself in an effort to show that his self-professed task is identical to theirs.

There are two types of genuine philosophers in Nietzsche’s late works: an old species that relied on a belief in “God” to legislate their values, and a new one that must do so without it. The former cannot perform their task after the death of God, which is why …

Iron Deficiency And Depressive Symptoms: Effects Of Racial And Ethnic Disparity In Two Reproductive-Aged Us Women, Alexis Monkhouse

USF Tampa Graduate Theses and Dissertations

Problem: Reproductive- aged women are one of the populations most at risk for iron deficiency and depression in the United States. While many studies have looked at the relationship between these two illnesses, none have explored it from a biocultural framework, examining how race/ethnicity affects this relationship. Using data from NHANES, this thesis examined the relationship between iron status (total body iron) and depressive symptoms (PHQ-9) among reproductive-aged women in the U.S. and how race/ethnicity affects it. Methods. NHANES survey data from 2005-2010 were pulled. Demographic and laboratory data were used to determine eligibility, total body iron, and depressive scores. …

Prosecutorial Philosophy And Racial Disparities In Arrest Rates, Carl L. Reeds

USF Tampa Graduate Theses and Dissertations

The prominent issue of racial disparities in arrest in the criminal justice system is well documented. One proposed mechanism for addressing these disparities in the criminal justice system is the emergence of progressive prosecutors. Progressive prosecutors are vastly different than traditional prosecution through the approach to their roles in the criminal justice system. Traditional prosecutors prioritize convictions and punishment, often seeking maximum sentences for defendants and relying on the traditional model of tough-on-crime policies. Progressive prosecutors pledge to reform the criminal justice system by declining to prosecute certain low-level offenses, expanding diversion programs, and explicitly addressing racial and socioeconomic disparities. …

District Leadership Influence On The Sustainability Of Dual Language Bilingual Education Programs, Jessica Hessler

USF Tampa Graduate Theses and Dissertations

Dual language bilingual education programs operate within policy environments that often constrain their long term viability, despite their deep historical roots in the United States. This qualitative study examined how district/central office leadership systems supported the sustainability of these programs. While prior research has emphasized school site collaboration between principals and teachers, limited attention has been given to the district/central office level leadership systems and strategies that shaped program coherence, implementation, and endurance. Guided by a framework integrating social justice leadership with principles of sustainable leadership, the study examined the research question: How do district or central office leadership systems …
