“He’S Got The Whole World In His Hands”: Seed Sovereignty And Agricultural Decision Making In Southeastern Kenya, Caroline Stahley

USF Tampa Graduate Theses and Dissertations

Increasing corporate control of the global seed supply and restrictions to local exchange threaten the autonomy of smallholder farmers and Indigenous communities. This project contributes to agricultural sovereignty movements by examining the decisions farmers make to address climate uncertainty, market volatility, and development agendas. Specifically, how is seed saving practiced and understood in relation to sovereignty? It reimagines what global food systems might look like if investment were directed to producers rather than intermediaries, arguing that cultivators lack support, not knowledge or capacity. Across these domains, seeds act as a motif to describe the concerns, innovations, and visions of farmers.

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 …

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 …

Amending Planting Media With Typha-Derived Biochar For Sustainable Horticulture, Elissa Touma

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 …

Quantitative Determination Of Nano Delivered Kras Sirna, Axel S. Deraspe

USF Tampa Graduate Theses and Dissertations

This study focuses on the development and validation of analytical methods for the detection of therapeutic KRAS-targeting siRNA in biological systems. Physicochemical characterization showed that p5RHH-formulated siRNA nanoparticles exhibit a controlled nanoscale size distribution, moderate polydispersity, and a negative zeta potential, suggesting colloidal stability and potential suitability for cellular uptake. Scanning electron microscopy confirmed a predominantly spherical morphology with a relatively uniform size distribution, consistent with dynamic light scattering measurements.

To enable accurate siRNA quantification, stem–loop reverse transcription (SL-RT) coupled with SYBR Green–based quantitative Polymerase Chain Reaction (qPCR) was optimized. Key parameters, including a primer concentration of 100 nM and …

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 …

How Location-Allocation Modelling Can Be Used To Site Pet-Friendly Evacuation Shelter Locations For Pet Owners In Hillsborough County, Florida: An Exploratory Study, Sarah A. Shaughnessy

USF Tampa Graduate Theses and Dissertations

Florida has been hit by some of the most destructive tropical cyclones in North America due to its relative location to the Gulf and Atlantic Ocean. Florida’s population growth since the 2000’s and the increased frequency of stronger storms because of climate change have made numerous emergency management leaders throughout the state get evacuation shelter networks established for public safety. However, the existing shelter network in Hillsborough County has become inadequate to satisfy the unprecedented population growth in that specific area since the COVID-19 pandemic and there’s a need for new shelter locations to better accommodate the growth when a …

The Long-Term Biological Toll Of Adverse Childhood Experiences And The Role Of Psychological Resilience, Jill Krier Desch

USF Tampa Graduate Theses and Dissertations

Adverse childhood experiences (ACEs) are preventable, potentially traumatic events that occur before age 18 such as physical, sexual, and emotional abuse, neglect, and household instability and are associated with the leading causes of adult morbidity and mortality in the United States. The mechanisms underlying these associations are not yet fully understood, but the link between ACEs, chronic stress, and allostatic load is one potential pathway. Although ACEs are associated with the leading causes of adult morbidity and mortality, many individuals continue to lead healthy lives through adulthood despite exposure to ACEs. This dissertation used data from Waves I – V …

Documenting Patterns Of Spring And Autumn Bird Bigration At Phillips Tract Research Area, A Stopover Site In The American Midwest, Janice K. Enos, Michael R. Avara, Tara A. Beveroth

North American Bird Bander

Stopover habitat, which is used by birds during migration to rest and refuel, is scarce in the American Midwest due to intensive agriculture. Protected woodlots and other small parcels of habitat do exist in the landscape, and may be important for migratory birds to utilize as stopover sites. Here, using mist netting techniques, we documented abundance and age specific patterns of spring and autumn migration at Phillips Tract Research Area, a protected parcel of land comprised of woodlots and mixed grassland plots. We found that 69 migratory species use this site as stopover habitat, and the most common (n ≥ …

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 …

Understanding The Impact Of Minority Stress On Mental Health Among Racially And Ethnically Diverse Adults: Insights From A Daily Diary Study, Ruba S. Rum

USF Tampa Graduate Theses and Dissertations

Minority stressors are theorized to contribute to mental health disparities for racial and ethnic minority individuals. While prior research links distal (i.e., external) and proximal (i.e., internal) minority stressors to adverse psychological outcomes for racial and ethnic minority groups, most studies have relied on cross-sectional designs that limit understanding of the immediate and short-term effects of minority stressors and potential protective factors in daily life. To address this gap, the present study examined the within-person daily associations between distal (interpersonal and vicarious discrimination, microaggressions) and proximal (internalized stigma, anticipation of rejection, identity management) minority stressors and psychological outcomes. Racial and …

Prosocial Behaviors As A Protective Factor Against Suicide Risk: An Ecological Momentary Assessment Approach, Bradley A. Brown

USF Tampa Graduate Theses and Dissertations

Suicidal ideation (SI) fluctuates substantially over short timescales, and the Interpersonal Theory of Suicide proposes that suicidal thinking emerges through dynamic interpersonal states involving perceived burdensomeness (PB), thwarted belongingness (TB), and hopelessness regarding these interpersonal states (IH). Although ecological momentary assessment (EMA) research has demonstrated that these risk factors fluctuate meaningfully within individuals and are associated with short-term changes in SI, comparatively little research has examined interpersonal processes that may attenuate suicide risk in real time. Prosocial behavior — voluntary actions intended to benefit others — may represent one such process, yet no known EMA study has examined whether prosocial …

Students In Motion: How Educators Enact Movement In Elementary Mathematics, Katherine E. Nash

USF Tampa Graduate Theses and Dissertations

This study used an exploratory sequential mixed-methods design to examine how elementary mathematics teachers report using physical activity in their instructional practice. The purpose of the study was to develop, provide evidence of validity, and implement a questionnaire to document the types of movement teachers use and when these practices occur in relation to mathematics instruction. In Phase 1, qualitative interviews were conducted with eight elementary mathematics teachers to identify common movement types and inform instrument development. The eight movement types that were identified are non-academic fine-motor, non-academic gross-motor, non-academic music-elicited, non-academic environmental, academic fine-motor, academic gross-motor, academic music-elicited, and …

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 …

Defining The Dynamic Role Of Belongingness In Alcohol Use Disorder Treatment, Brendan E. Walsh

USF Tampa Graduate Theses and Dissertations

Drinking is intertwined with social processes, including social support and group belongingness. Although drinking can transiently enhance social functioning, escalating to heavy use can be detrimental to it. It is well-known that excessive drinking and social dysfunction exacerbate each other over time, and it follows that social support and belonging are key mechanisms of addiction recovery. Yet, less is known about how changes in belongingness throughout treatment dynamically affect drinking outcomes, and even less is known about how drinking outcomes and other social processes (e.g., therapeutic alliance, interpersonal drinking consequences) dynamically influence belongingness. The current project (N = 210) studied …

Examination Of Gastrointestinal Visceral Sensitivity In The Maintenance Of Restrictive Eating Disorders, Kendall N. Poovey

USF Tampa Graduate Theses and Dissertations

Aversive conditioning theories of restrictive eating disorders propose that gastrointestinal (GI) visceral sensitivity (i.e., hypervigilant monitoring and worry about GI sensations) is implicated in the maintenance of restrictive eating disorders (i.e., anorexia nervosa [AN], atypical anorexia nervosa [AAN], and avoidant/restrictive food intake disorder [ARFID]). Specifically, a negative reinforcement process is posited in which disordered eating behaviors (e.g., restriction, purging) help to mitigate or avoid GI-related distress, and are thereby reinforced. However, this theorized process has yet to be tested. For the current study, participants from the University of South Florida and surrounding Tampa community who screened positive for a restrictive …

Spying The Lie: Insider Threat Prevention In National Security, Jazma M. Parker
