Learning Analytics: An Innovative Technological Tool To Help Increase Student Retention And Graduation Rates In Us Higher Education Institutions, Fednold Thelisdort

USF Tampa Graduate Theses and Dissertations

Higher education institutions (HEIs) have embarked on a journey of innovation by adopting learning analytics (LA) in their operation, offering a more sustainable and innovative technological tool to increase student retention and graduation rates in US HEIs. LA, an emerging academic and technological tool, equips HEIs to gather, analyze, and interpret their students’ data. Since the publication of the first (conceptual) framework by Burke (2019), LA has matured into a research focus and practice, implemented in several institutional contexts at different scales and disciplinary/pedagogical contexts. This study explored the impact of the use of LA on student retention and graduation …

Physical Activity And Functional Mobility In Adults With Hearing Loss: A Series Of Embedded Studies Within A 6-Month Clinical Trial With Hearing Aids, Sarah L. Bochat

USF Tampa Graduate Theses and Dissertations

Adults with hearing loss engage in low levels of physical activity and demonstrate poor performance on measures of functional mobility. The impact of hearing rehabilitation on these outcomes is not fully understood. Previous investigations were largely quantitative and focused on older adults ≥ 65 years of age who may respond differently to hearing intervention than relatively younger adults. They also tended to focus on exercise rather than global engagement in physical activities and did not report hours of hearing aid use, an important indicator of intervention success. One purpose of this dissertation was to determine the feasibility of collecting accelerometry-assessed …

Teaching Word Combinations Using Matrix Training Via Serious Gaming In Minimally Verbal Children, Nataly Innamorato

USF Tampa Graduate Theses and Dissertations

This dissertation addresses the communication challenges faced by minimally verbal children who use Augmentative and Alternative Communication (AAC), often limited to one-word expressions. The approach used involves gamifying matrix training, an empirically supported method for teaching word combinations and promoting the generalization of language skills. Across three studies, the development of an instructional game is described and evaluated with two populations, typically developing children and children who are minimally verbal. First, it introduces a gamified application of matrix training that provides training in an interactive digital environment. Second, a proof-of-concept was obtained via a multiple baseline across participants with typically …

Changes In Immune-Regulated Gene Methylation Over Time In Women Who Do And Do Not Develop Breast Cancer, Kyle Laney

USF Tampa Graduate Theses and Dissertations

Breast cancer survivors face elevated risks of chronic inflammatory conditions and immunedysfunction compared to the general population. These elevated health risks in survivors are well-documented but mechanistically poorly understood. This study aimed to characterize longitudinal changes in DNA methylation patterns of immune-regulatory genes in women who developed breast cancer compared to cancer-free controls. We conducted an EWAS using Sister Study cohort data, analyzing longitudinal changes in DNA methylation by comparing the difference in beta values between pre- and post-diagnosis time points in breast cancer cases versus changes over the same period in cancer-free controls. The analysis included 414 participants: 189 …

Applications Of Contracting Self-Similar Groups To Cryptography And Scale Groups, Arsalan Akram Malik

USF Tampa Graduate Theses and Dissertations

Given their peculiar properties, self-similar groups are of great interest both from applications and theoretical standpoints. In this work we study the scope of their applications in post-quantum cryptography and in constructing scale groups via lifting maps.

We propose self-similar contracting groups as a platform for cryptographic schemes based on simultaneous conjugacy search problem (SCSP). This class of groups admits fast polynomial-time algorithms for the word problem and element multiplication that can be used for effective encryption and decryption of messages. It contains extraordinary examples like the Grigorchuk group, which is known to be non-linear, thus making some of existing …

Healthy Bodies, Moral Minds, And Rural Ideals: Contextualizing Interwar British Childhood And Citizenship Through Children's Country Holidays Fund Vacations, Paula J. Pack

USF Tampa Graduate Theses and Dissertations

This dissertation uses the Children’s Country Holidays Fund (CCHF) as a critical lens to examine how philanthropy, childhood, class, public health, and rural nostalgia intersected within the broader context of citizen formation in interwar Britain. Founded in 1884 to provide country holidays for poor London schoolchildren, the CCHF evolved from a philanthropic response to Victorian slum life into an informal arm of welfare governance by the end of the interwar period. Through its country holidays, the Fund became an active participant in shaping ideals of health, morality, and civic responsibility in a period marked by heightened concern over national vitality …

Democracy, Expertise, And The Disinformation Problem, Richard Randall Frohock Iv

USF Tampa Graduate Theses and Dissertations

Experts are an essential part of our social epistemology. They grant us access to knowledge that would otherwise be inaccessible. Because of this, experts are also typically seen as invaluable political contributors. Without expert contributions, public policy risks being ill-informed and therefore incapable of addressing society’s needs. Recently, however, the extent to which expertise should inform public policy has come into question. Fueled largely by disinformation, there is a growing movement against traditional experts. Those within this movement argue that experts have overstepped their bounds and are working against the societies they are meant to be helping. Fearing that that …

Algorithms Of Eversion: Contemporary States And Digital Sovereigns, James Libengood

USF Tampa Graduate Theses and Dissertations

The rapid development of artificial intelligence (AI), the internet of things (IoT), and digitization have pushed digital sovereignty to the top of the governance agenda in the 21st century. This notion is expanded upon in this work through seven chapters encompassing theoretical underpinnings, methodological frameworks, and real-world case studies. It shows how multinational corporations dominate digital coloniality, and how the merge of physical and digital reality or eversion poses challenges. The study compares contrasting governance approaches, such as the European Union’s General Data Protection Regulation (GDPR), geared to ethical AI and data protection, versus BRICS nations’ stance on data localization …

Exploring Culturally Responsive Literacy Practices In Prekindergarten: A Multimodal Approach By Teachers, Deeksha Thonta Aradhya

USF Tampa Graduate Theses and Dissertations

Children from culturally and ethnically diverse backgrounds are often expected to learn within different cultural contexts than those they have experienced in their families, homes, and communities. Some children are rarely exposed to the dominant culture and practices that are highly valued in schools before entering early education settings. When they start (pre)school, young children are often expected to immediately participate in cultural practices that may differ from those at home, which are considered indicative of being successful, ready, or capable. This research aimed to investigate the culturally responsive literacy practices used by teachers in a laboratory prekindergarten classroom. The …

Cinematic Abuse: A Critical Analysis Of Disney’S “Happily Ever After” In The Little Mermaid, Aladdin, And The Princess And The Frog, Erin Michelle Gough

USF Tampa Graduate Theses and Dissertations

This dissertation examines the manner in which three animated Disney princess films cultivate stereotypes and gendered behaviors consistent with domestic violence and thereby encourages viewers to accept and tolerate abuse against women. I argue that due to the dangerous, constricting, and sexist gender roles encouraged by the Walt Disney Corporation, films prime young girls and boys to react to social situations and encounters in a way that mirror the characters’ reactions. Because of the films’ entertainment value, most of the characters’ inappropriate, stereotypical, and often violent behaviors either go unnoticed or are passively accepted. The violence does not have to …

The Epistemologization Of Scientific Knowledge: Scientific Textbooks And Education In The 18th And 19th Centuries, Brian P. Bieganski

USF Tampa Graduate Theses and Dissertations

Philosophy, despite its proclivities towards history and contextualization, often neglects to properly note various characteristics of ideas. In particular, there seems to be a kind of blindness to a key component of how ideas come into being: namely, the role of writing that leads to the preservation and transmission of ideas. Textbooks, for instance, are a key instrument for containing, disseminating, and archiving knowledge of a specific domain that can be used to introduce those complex concepts to newcomers and the unspecialized. As such, a textbook is an epistemic device used for transmitting a condensed constellation of ideas, concepts, formulas, …

Evaluating Behavioral Skills Training To Teach Salsa Dancing Skills To Adults With Autism Spectrum Disorder And/Or Intellectual Disabilities, Joshua I. Nieves

USF Tampa Graduate Theses and Dissertations

Research has demonstrated behavioral skills training (BST) to be an effective teaching procedure for acquisition of a variety of skills among both neurotypical and neurodiverse individuals across different ages. Moreover, recent studies have demonstrated the effectiveness of BST for enhancing sports performance when training neurotypical children and adults. However, there is limited research on the effectiveness of BST for enhancing sports performance, and specifically dance performance, among individuals with autism spectrum disorder (ASD) and/or intellectual disabilities (ID). Dance is a recreational activity that can serve as a form of physical activity for children and adults. Salsa is a Latin style …

Hierarchical Reinforcement Learning (Hrl) In Multi-Goal Spatial Navigation With Autonomous Mobile Robots, Brendon Johnson

USF Tampa Graduate Theses and Dissertations

Hierarchical reinforcement learning (HRL) is hypothesized to be able to take advantage of the inherent hierarchy in robot learning tasks with sparse reward schemes, in contrast to more traditional reinforcement learning algorithms. In this research, hierarchical reinforcement learning is evaluated and contrasted with standard reinforcement learning in complex navigation tasks. We evaluate unique characteristics of HRL, including their ability to create sub-goals and the termination function. We constructed experiments to test the differences between PPO and HRL, different ways of creating sub-goals, manual vs automatic sub-goal creation, and the effects of the frequency of termination on performance. These experiments highlight …

An Evaluation Of Check-In/Check-Out For Children With Emotional And Behavioral Disorders, Norma E. Guillen

USF Tampa Graduate Theses and Dissertations

Children with emotional and behavioral disorders (EBD) often display disruptive behavior that can hinder their learning and negatively affect the classroom environment. Check-in/Check-Out (CICO) is a Tier-2, evidence-based intervention designed to support children who have difficulty engaging in classroom activities and are at-risk of developing more severe challenging behavior. The primary goal of the intervention is to prevent the escalation of these behaviors and reduce the need for more intensive individualized interventions. However, limited research exists on the effectiveness of CICO for children with emotional and behavioral disorders (EBD). This study examined the effects of CICO on improving on-task behavior …

Bridging Virtual Robots And Physical Tasks Via Augmented Reality, Xiangfei Kong

USF Tampa Graduate Theses and Dissertations

Entry to human-robot interaction research, e.g., conducting empirical experiments, faces a significant economic barrier due to the high cost of physical robots, ranging from thousands to tens of thousands. This cost issue also severely limits the field’s ability to replicate user studies and reproduce the results to verify their reliability, thus offering more confidence to incorporate these findings. Although virtual reality (VR) user studies present a potential solution, it is unclear whether we can confidently transfer the findings to physical robots and physical environments because VR isolates both the physical robot and the physical world where robots operate. To address …

Sustaining The Spark: Professional Learning For The Seasoned Principal, Jennifer C. Mccrystal

USF Tampa Graduate Theses and Dissertations

Principals play a pivotal role in shaping student achievement and supporting teacher success. However, the limited existing research reveals that professional development opportunities for principals, especially seasoned ones, are often uninspiring, inadequately designed, and disconnected from their actual needs. As a result, seasoned principals may face challenges in maintaining motivation, engagement, and continued leadership development. This study addresses this gap by investigating how seasoned principals perceive and value professional learning, focusing specifically on their pinnacle experiences—those they regard as the most impactful and significant throughout their careers.

Using a narrative inquiry approach with an Appreciative Inquiry lens, this study captures …

Psychopathy, Emotion, And Mock Juror Decision-Making, Bailey A. Hall

USF Tampa Graduate Theses and Dissertations

Research suggests that mock jurors impose harsher sentencing (including death sentencing) when defendants are described as psychopathic, but reasons for this are unclear. This preregistered study investigated the role of juror anger and cognitive biases (predecisional distortion [PDD]) in the relationship between defendant psychopathy descriptions and mock juror decision-making. In an online experiment, participants (undergraduates in a large Southeastern university [n=410] and a US Census-representative online sample [n=384]) reviewed case facts of a murder, were randomized to expert witness testimony of defendant psychopathy or control conditions and read the prosecution and defense arguments before sentencing the defendant to death or …

Adapting And Evaluating A Positive Psychology Intervention For Children With Cancer And Their Families, Camryn Legra

USF Tampa Graduate Theses and Dissertations

This study utilized a mixed methods approach in two phases. The first phase entailed adapting an evidence-based positive psychology intervention—the Well-Being Promotion Program (WBPP; Suldo, 2016)— for children with pediatric cancer. The WBPP has mostly been provided to students at public schools, and to the researcher’s knowledge, has never been used for children with pediatric cancer. To make it culturally appropriate for this group of students, adaptations were made by collecting input and recommendations from a sample of two caregivers of children with pediatric cancer who participated in a focus group. A micro-interlocutor analysis (Onwuegbuzie et al., 2009) was completed …

"You Should Not Judge, You Should Understand": The Effects And Perceptions Of An Empathy Embedded Teacher Inquiry Framework, Erica J. Milor

USF Tampa Graduate Theses and Dissertations

A slew of challenges make up the landscape of special education today-from teacher shortages to lack of resources and vast inequities. Teachers must be able to effectively address the diverse needs of students in the midst of the aforementioned challenges at a micro, meso, and macro level. Teacher Inquiry, an iterative problem-solving cycle, is an effective framework for teachers to do so. The purpose of this study was to develop a systematic empathy-embedded problem-solving cycle for special education teachers in order to increase student progress and effective problem-solving in the educational setting, while exploring how teachers say they perceive this …

Branding In The Spotlight: The Impact Of Name, Image, And Likeness (Nil) On Athlete Brand Image In College Athletics, Timothy Jeremiah Ervin Ii

USF Tampa Graduate Theses and Dissertations

This qualitative thesis explores the impact of Name, Image, and Likeness (NIL) on athlete brand image within college athletics, with a focus on the lived experiences of men and women college basketball players. Through in-depth, semi-structured interviews with eight Division I athletes, the study examines how NIL has influenced personal branding, identity construction, and public visibility. Guided by brand identity theory and athlete brand image, and analyzed using Braun and Clarke’s thematic analysis, four central themes emerged: athlete (brand) empowerment, legacy through authenticity, navigating influence, image, and objectification, and economic viability and opportunity. Additionally, the concept of self-presentation emerged as …

Integrating Motivational Traits Into The Approach-Avoidance Distinction, Wesley D. Gardiner

USF Tampa Graduate Theses and Dissertations

This thesis investigates the potential for integrating motivational traits into the established approach-avoidance motivational framework, which describes individuals’ general tendencies to seek pleasure and avoid pain. Although various theories and empirical studies have advanced our understanding of approach-avoidance motivation, critical constructs such as achievement motivation and trait anxiety have often been overlooked or misoperationalized. Addressing these gaps, the current study integrates Kanfer and Heggestad’s (1997) motivational trait taxonomy with constructs from achievement goal orientation, regulatory focus theory, and reinforcement sensitivity theory. This research evaluated a hypothesized two-factor model of approach and avoidance motivation using confirmatory and exploratory factor analyses with …

An Evaluation Of The Prevent-Teach-Reinforce Secondary (Ptr-Sec) Model For Middle School Students With Emotional And Behavioral Disorders, Kevin R. Ochoa Casas

USF Tampa Graduate Theses and Dissertations

Students with emotional and behavioral disorders (EBD) may encounter a wide range of challenges in academic settings. Despite several initiatives aiming to address these challenges in the school setting, research indicates that school-based professionals are still struggling to adequately support this population, using the individualized functional behavior assessment and behavior intervention plan (FBA-BIP) process. The Prevent-Teach-Reinforce (PTR) model utilizes a manualized, team-based approach to streamline the individualized FBA-BIP process. However, more research is needed to assess the effectiveness of the PTR model to better support middle school students with EBD, particularly, in the areas of generalization and maintenance effects. This …

Effects Of Antecedent Choice On Academic Engagement And Disruptive Behavior In The Classroom, Ivy Grace E. Morgan

USF Tampa Graduate Theses and Dissertations

The number of students enrolled in public school systems receiving special education services continues to increase. Students diagnosed with autism spectrum disorder (ASD) and those classified with emotional disturbance (ED) often engage in challenging behaviors such as inappropriate outbursts, disruptive behaviors, and off-task behavior that distract other students from learning. These behaviors can negatively impact educational outcomes for both the student and their classmates. Unfortunately, teachers often lack adequate training in addressing disruptive behavior in the classroom and have limited access to feasible interventions. Across-activity choice is a feasible antecedent intervention teachers can use in the classroom. It allows students …

Do Emotion Malleability Beliefs Buffer Social Ostracism? An Experimental Investigation, Bingjie Tong

USF Tampa Graduate Theses and Dissertations

Social ostracism is linked to adverse psychological outcomes, including increased suicide risk among college students. This study examined a manipulation targeting emotion malleability beliefs and its effect on psychological outcomes after a lab-induced social ostracism task (Cyberball). Psychache, a well-established predictor for suicide risk, was examined as a potential moderator variable. College students (N = 243) were randomly assigned to either an experimental condition, which presented information stating that emotions are malleable, or a neutral control condition. Participants in the experimental condition reported a greater increase in beliefs about emotional malleability, greater use of cognitive reappraisal, and less perceived burdensomeness …

"You Need To Make The Decision You Can Live With": An Observational Study Of Anti-Abortion Centers In Tampa Bay, Anna Broich

USF Tampa Graduate Theses and Dissertations

Anti-Abortion Centers (AACs) pose a grave threat to the reproductive health outcomes of Americans. Disguising themselves as licensed health clinics, AACs target vulnerable communities to prevent or delay abortion care through the spread of medical misinformation, contributing to abortion stigmatization. Situated in a state with a near-total abortion ban, this secret-shopper study aimed to understand the ways in which AACs in Tampa, Florida communicate anti-abortion rhetoric to pregnant people seeking abortions. Under the guise of people who suspect they are pregnant searching for abortion care, the main researcher and her assistants conducted the first phase of the study through 25 …

Reparative Cuteness: Summer Camp Island’S Obfuscated Streaming Distribution Reveals Our Dependence On Monetary Care, James R. Hanjian

USF Tampa Graduate Theses and Dissertations

Summer Camp Island exhibits the culmination of the animation styles and ethics of dependent care produced within contemporary Cartoon Network animations. As part of the production cycle of Warner Bros. animated television programs following Adventure Time, Julia Pott’s animated program depicts networks of collaborative care informed by the lived realities of the creator-animators. By employing a reparative reading of the narratives and cute aesthetics which appear in the program, I maintain that the care networks presented within the diegesis of Summer Camp Island depict alternatives to the precarious economic and industrial realities that actively shaped the show’s production and distribution. …

Just A Spark Of Imagination: Examining Professional Development For Gifted Educators, Jennifer J. Tucker

USF Tampa Graduate Theses and Dissertations

This qualitative study explored how teachers of gifted education in a large southeastern school district perceive the high points of professional development to reimagine learning courses to encourage professional learning. In today’s changing field of education, there is an urgent need to foster teachers’ professional growth to create an environment where they feel supported to retain their expertise in the educational field. Many studies focus on students' needs, but the voice of the teacher's needs is missing from the study. Gathering narratives from teachers of gifted students empowers the teachers’ perspectives to be included in discovering how to reimagine professional …

New Attack Surfaces Against Emerging Cloud And Web Based Infrastructures And Defenses, Junjie Xiong

USF Tampa Graduate Theses and Dissertations

Emerging network security threats, ranging from cloud-based infrastructure attacks to web-based content subversion, pose significant challenges to modern computing environments. In this dissertation, we explore two novel attack vectors that disrupt both cloud-based infrastructures and web-based content systems.

In this dissertation, we first introduce the Warmonger attack, a novel attack vector that can cause denial-of-service between a serverless computing platform and an external content server. The Warmonger attack exploits the fact that a serverless computing platform shares the same set of egress IPs among all serverless functions, which belong to different users, to access an external content server. As a …

Surface Acoustic Wave Energy Driven Degradation Of Aqueous-Based Methylene Blue, Xieqi Gu

USF Tampa Graduate Theses and Dissertations

This study investigates the degradation behavior of methylene blue (MB) under surface acoustic wave (SAW) excitation, focusing on the effects of power, frequency, hydrogen peroxide (H2O2) concentration, and the use of perovskite oxide catalysts (LFO and LSF). Initial experiments showed that MB concentrations remained stable under SAW at ~10 MHz and ~30 MHz with power levels of 1–3 W in the absence of H2O2, though solution temperatures increased. Upon introducing 1 M H2O2, MB degradation followed a second-order rate constant, with degradation rates increasing with power and significantly higher at ~30 MHz, suggesting that both frequency and power enhance free …

Increasing Behavior-Specific Praise Use And Variability With Secondary Education Teachers Using Behavioral Skills Training, Tactile Prompts, And Multiple Exemplars, Cecilia Pannone

USF Tampa Graduate Theses and Dissertations

Teachers often receive minimal training in classroom management strategies, leading to punitive-based teacher-student interactions. Negative interactions (e.g., reprimands) may decrease behaviors momentarily but do not yield lasting behavior change. Behavior-specific praise (BSP) is a low-response effort classroom management strategy that positively impacts students’ behaviors and academic performance. However, training does not guarantee that BSP will be used throughout the academic years or across student cohorts, leading teachers to revert to negative interactions to manage classroom behaviors. Limited research has investigated the components of praise that increase effectiveness and saliency. This study aimed to increase teachers’ use of BSP using tactile …
