Maturing Out Of Crime: A Test Of The Integrated Maturation Theory Of Desistance, Kelly E. Kortright

USF Tampa Graduate Theses and Dissertations

This dissertation partially tested a newer integrated theory, the Integrated Maturation Theory (IMT) of desistance. IMT argues that as maturation increases across five maturation domains (social role, civic, identity, psychosocial, and neurocognitive) the likelihood of offending decreases. Using a sample of serious justice-involved juveniles spanning ages 14-24 from the Pathways to Desistance Study, the individual and simultaneous maturation domain development of the social role, civic, identity, and psychosocial maturation domains, were explored for heterogeneity. Using a group-based trajectory modeling approach, including multi-trajectory modeling, this study advanced the understanding of maturation development by identifying sub-groups following declining trajectories of maturation and …

Advancing Adversarial Audio: Human-In-The-Loop Black-Box Attacks, Rui Duan

USF Tampa Graduate Theses and Dissertations

Adversarial audio attacks pose significant security challenges to real-world audio applications. Attackers may manipulate speech to impersonate a speaker, gaining access to smart devices like Amazon Echo. In audio applications, there are two key areas: music and speech. In music, most attackers create a small noise-like perturbation on the original signal to evade copyright detection. However, this method degrades music's perceived quality for human listeners. In the speech, creating an adversarial example often requires many queries to the target model, a process too cumbersome for practical use in real-world scenarios, like interacting with smart devices numerous times.

In this dissertation, …

Teacher-Implemented Accumulated And Distributed Schedules In The Classroom Setting, Jessica S. Benevides

USF Tampa Graduate Theses and Dissertations

Emotional behavior disorders (EBDs) are becoming increasingly more common in schools (Forness et al., 2012). Challenging behavior can negatively impact a teacher’s implementation of classroom management strategies which can be detrimental to student outcomes (Garwood et al., 2017; Gilmour et al., 2022) and increase the risk for teacher burnout (Fernet et al., 2012). Evidence-based strategies such as differential reinforcement have been shown to be effective at reducing challenging behavior (Boniecki & Moore, 2003; Petscher et al., 2009). Moreover, accumulated and distributed reinforcer arrangements using tokens have been shown to both reduce challenging behavior and increase task engagement (Chen et al., …

Skinny And Curvy And Muscular, Oh My! Examining Co-Occurring Appearance Ideals And Associated Disordered Eating In College Women, Laura E. Boyajian

USF Tampa Graduate Theses and Dissertations

Research examining appearance ideal internalization has primarily focused on the thin ideal, neglecting the growing importance of alternative appearance ideals (e.g., curvy, muscular). Qualitatively, women report that these ideals are not internalized in isolation, but instead, are internalized simultaneously. Importantly, the simultaneous internalization of appearance ideals may enhance the negative effects of appearance ideal internalization. The current study tested whether simultaneously internalizing diverse appearance ideals (i.e., thin, curvy, muscular) was associated with increased body dissatisfaction and disordered eating behaviors in a predominantly White (Study 1; N= 260) and racially/ethnically diverse (Study 2; N=264) samples of college-aged women. Participants reported the …

From Guns To Intimate Partner Violence: The Impact Of Power And Control, Meaghan E. Brown

USF Tampa Graduate Theses and Dissertations

Gun violence and intimate partner violence are pervasive public health concerns across the globe. Notably, previous literature has shown a positive relationship between gun ownership and intimate partner violence (IPV), even when a gun is not used during acts of IPV. Despite this established link, few studies to date have explored psychological mechanisms, especially feelings of and desire for power, that could explain this relationship among young men. Given that college students remain one of the most at-risk groups for both victimization and perpetration of IPV, examining the relationship between actual or intended gun ownership and IPV could close vital …

Trajectories Of Well-Being: Results From The Americans’ Changing Lives Study, Cassondra M. Lyman

USF Tampa Graduate Theses and Dissertations

There is considerable interest in elucidating the dynamics of well-being over long periods of time, including how well-being dynamics are influenced by depression. The Americans' Changing Lives (ACL) study has followed the health and well-being of a nationally representative sample of adults in the United States for 25 years (N1986 = 3,617; N1989 = 2,867; N1994 = 2,562; N2002 = 1,787, N2012 = 1,427). Leveraging data from the ACL study, the present investigation employed growth mixture models to identify unobserved subpopulations (i.e., latent classes) typified by change in well-being over time. Three predominant trajectories for well-being were identified: relative stability …

An Assessment Of A Haptic-Based Ergonomic Intervention At An Aerospace Manufacturing Facility, Chase Mcdonald

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis was to evaluate the effectiveness and sustainability of a haptic-based intervention designed to reduce hand motions and, consequently, the risk of musculoskeletal disorders (MSDs) among operators in a manufacturing facility. The intervention involved using ergonomic gloves equipped with haptic feedback, intended to encourage proper hand motion and reduce unnecessary movements.

Over a six-month period, data was collected from operators wearing the haptic gloves, focusing on two key metrics: Duty Cycle and Motion Rate. These metrics were chosen to normalize the data, accounting for the variability in duration for each individual operator who wore the device. …

Additionally, the effect of the previous day’s exposure to heat stress was investigated. Illness and injury records were collected during the Deepwater Horizon oil spill response. All OSHA recordable EHI cases were extracted for study. The highest estimated WBGT and HI on the day of incident were compared to the prior day. The overall incidence of recordable EHIs was 0.74 cases/100 FTE and the incidence for exposures ≥ …

“She’S On Her Way Up”: A Case Study Of Mercy Otis Warren And The Gendered Politics Of Commemoration, Sara Ann White

USF Tampa Graduate Theses and Dissertations

In 2001, a statue of eighteenth-century Bill of Rights advocate Mercy Otis Warren was erected on the Barnstable County Superior Courthouse lawn in Barnstable, Massachusetts. The story of the statue’s eventual placement is a fascinating case study of how the gendered politics of commemoration can play out over time in local communities. The saga of Warren’s commemoration is inextricably bound up with the history of efforts to commemorate Warren’s brother, James Otis Jr., and eventual arguments that Warren’s work deserved recognition in its own right. We first see gendered politics at play as Warren’s real accomplishments were consistently overshadowed by …

Unveiling Ferroelectric And Multifunctional Insights In Hybrid Formate Perovskites, Abduljelili Popoola

USF Tampa Graduate Theses and Dissertations

Formate perovskites, denoted as AB(HCOO)3, represent a diverse group of hybrid organic-inorganic compounds, renowned for their numerous phase transitions and a wide array of properties. These properties encompass (anti)ferroelectricity, ferroelasticity, (anti)ferromagnetism, and multiferroism. Despite extensive research on these materials, a comprehensive examination of their properties across a substantial number of formate perovskites remains scarce. This scarcity stems from structural complexity of these materials, potential systematic errors arising from different measurement techniques or incomplete data. For instance, data for critical parameters like piezoelectricity, dielectricity, and elasticity tensors have been lacking.

In this study, we address these challenges by employing first-principles density …

Specification, Enforcement, And Measurement Of Integrity Policies, Kevin Dennis

USF Tampa Graduate Theses and Dissertations

The first step to improving an organization's security posture is to define the organization's security goals. At a technical level, these goals are expressed as security policies. Security policies are predicates over programs, that return true or false if the program adheres to the policy. Defining these policies correctly is thus essential to ensuring the overarching security goals are met, but it is often quite difficult to translate human-oriented goals into their technical policy counterparts. In addition, these policies must be specified so that they are enforceable while minimizing false positives and false negatives. Integrity policies, which specify how data …

Enhancing Novice Teachers’ Social Justice Practices Through Critical Professional Learning: A Critical Participatory Action Research Study, Brianna C. Connors

USF Tampa Graduate Theses and Dissertations

There is a crucial need for social justice-oriented educators in today's classrooms given the growing population of America's multicultural student population. Social justice-oriented teacher preparation programs (TPPs) have contributed significantly to shaping the pedagogies of teacher candidates, better equipping them to serve all students. The transition period following teacher candidates' engagement in the TPPs, however, presents political, contextual, and personal challenges for novice teachers (NTs) dedicated to teaching for social justice. This research presents findings from a critical participatory action research (CPAR) study delving into the experiences of NTs engaged in critical professional learning (CPL).

Investigating The Impact Of Inverter-Based Resources On Power Grid Dynamics, Ratik Mittal

USF Tampa Graduate Theses and Dissertations

This dissertation explores the stability challenges posed by integrating Inverter-Based Resources (IBR) into power grids, particularly focusing on two major scenarios: IBRs connected to weak grid interconnections and their performance in series-compensated networks. With the increasing dependency on renewable energy sources, ensuring the stability of these grids is crucial. A multilayered investigative approach is employed, utilizing Electromagnetic Transient Simulations that model grid systems interfaced with IBRs. These simulations are pivotal as they emulate real-world stability issues and provide a foundational understanding of grid interactions. In this dissertation two major types of IBR control are modeled and analyzed: Grid Following Control …

Exploring The Enlightenment Function Of Thought Experiments: Unveiling An Underdeveloped Dimension Absent In Typologies, Dominique Greene-Sanders

USF Tampa Graduate Theses and Dissertations

Thought experiments (TEs) are imaginative tools used across various fields to explore theoretical and practical issues. This dissertation focuses on the application of TEs in ethics, specifically emphasizing the underdeveloped enlightenment function. The traditional use of TEs in ethics often aims to clarify, support, or refute specific claims through an argumentative structure. However, this work argues that TEs also play a key role in enhancing ethical competence by acknowledging the complexities of ethical dilemmas and fostering moral skills like critical thinking, moral reasoning, and ethical awareness through non-argumentative and non-theory-centric means.

The dissertation begins by explaining the nature and historical …

The Dialectics Of Faith: Kierkegaard, Irony, And Conversion, Douglas Zimmerman

USF Tampa Graduate Theses and Dissertations

Kierkegaard, the 19th-century Danish philosopher, offers a profound perspective on conversion. According to him, conversion isn't a mere external change, but a deeply personal and internal transformation. It's about moving from a state of despair to faith. Kierkegaard believed that true conversion involves a passionate leap of faith, where an individual confronts their own subjectivity and makes a conscious, often paradoxical, choice to align themselves with their authentic values and spiritual beliefs. In his view, conversion is a constant process, requiring introspection, struggle, and a commitment to live authentically in the face of life's uncertainties. In order to communicate this …

SARS-CoV-2 is an airborne respiratory virus that primarily infects the lungs via the ACE2 receptor but has well-documented secondary target organs including the kidneys, the gastrointestinal tract, the heart, and the skin. SARS-CoV-2 also infects the brain, but the hematogenous route of viral entry to brain is still not fully characterized. Understanding how SARS-CoV-2 traverses the blood-brain barrier (BBB) as well as how it …

The Polyaneuploid Cancer Cell State And Therapeutic Resistance: Eco-Evolutionary Dynamics In Structured Populations, Anuraag Bukkuri

USF Tampa Graduate Theses and Dissertations

In this dissertation, I develop and apply eco-evolutionary modeling techniques to understand how the polyaneuploid cancer cell (PACC) state, entered when aneuploid cells exit the cell cycle after S phase and undergo a whole genome duplication, contributes to therapeutic resistance. Since resistance remains one of the primary causes of treatment failure in cancer patients, it is critical to understand how such demographic state transitions allow for acclimatization of cancer cells to therapeutic stressors and how they interact with evolutionary processes to promote irreversible resistance.

In Chapters Two and Three, I lay the foundation for this work. In Chapter Two, I …

Classifying Traumatic Brain Injury: Associations With Executive Functioning And Externalizing Behavior, Lauren F. Fournier

USF Tampa Graduate Theses and Dissertations

Traumatic brain injury (TBI) involves a head injury that is, for some individuals, associated with long-term behavioral difficulties, including externalizing behaviors. The literature on TBI and its links to externalizing is limited in several important ways. First, there is evidence that current classification system of mild, moderate, or severe is imprecise and contains important variation within TBI categories. Second, TBI and externalizing are understudied among high functioning individuals, such as undergraduate students, despite rates of TBI among this population that are similar to those of the general population. Third, while it is theorized that executive functioning deficits explain the association …

Essays On Machine Learning And Corporate Disclosure, Zicheng (Leo) Xiao

USF Tampa Graduate Theses and Dissertations

This dissertation contains two essays that shed new light on the dynamic of information disclosure on the capital market. For both two essays I leverage computational linguistics and 20 million turns of dialogues from earnings conference calls from 2006-2022. In the first essay, I introduce a novel measure that quantifies the disparity in narrative focus between managers’ disclosures and analysts’ questions during these calls, denoted as Topic Attention Divergence (TAD). A higher level of TAD indicates a higher level of firm-investor asymmetry and lower information quality. My results confirm that higher TAD in earnings conference calls inversely (positively) predict firms’ …

The Joint Effects Of Sleep And Pain, And Moderations By Work Characteristics, Christina Xuong Mu

USF Tampa Graduate Theses and Dissertations

Reactivity describes interindividual differences in the physiological or emotional responses following an antecedent stressor. For instance, higher stressor reactivity to shorter sleep (i.e., those who report greater stressor severity following shorter-than-usual sleep) and higher negative affective reactivity to stressors (i.e., those who report more negative affect following a stressful event) have worse mental and physical health. Pain reactivity to shorter sleep is a novel concept that describes differences in pain responses following a night of shorter-than-usual sleep. Higher pain reactivity to shorter sleep means that individuals report more pain locations or higher pain severity following shorter-than-usual sleep the previous night, …

Us Elementary Teachers’ Perspectives With The Use Of Rubrics In Elementary Classrooms: A Shift From Traditional Assessment To Alternative Assessment, Roaa Adel Alajaji

USF Tampa Graduate Theses and Dissertations

This study was conducted to explore US elementary teachers’ perceptions of their experiences using rubrics as a tool for student self-assessment and metacognition (assessment for learning) to improve elementary students’ achievement and their instructional decision-making at a private American elementary school in South Florida. The constructivist learning theory by Piaget (1970) and Vygotsky (1978), which emphasized that knowledge is best gained through the interaction of experiences and ideas in one’s mind and the interaction with others, framed the study. Three semi-structured interviews were conducted with eight elementary teachers: three third-grade teachers, three fourth-grade teachers, and two fifth-grade teachers. Using thematic …

Navigating Shrinking Cities: Towards Coordinated Urban Development From The Perspective Of Flow And Network, Yuzhou Chen

USF Tampa Graduate Theses and Dissertations

As cities worldwide undergo rapid but uneven changes, proposing smart and sustainable urban development strategies has been a popular interdisciplinary research in the 21st century. In particular, the phenomenon of shrinking cities characterized by economic recession and population decline is becoming increasingly severe in developed countries and even developing countries. In the real world, research focusing on individual shrinking cities often neglects the interconnectedness between cities within the network formed by flows. Therefore, coordinating the development strategies for multiple closely connected cities, especially for shrinking cities, is a step up from focusing on individual cities.

This dissertation aims to propose …

Essays On The Determinants Of Women's And Children's Health In Bangladesh, Md Shahjahan

USF Tampa Graduate Theses and Dissertations

My dissertation is titled "The Determinants of Women's and Children's Health in Bangladesh." The first chapter studies the impact of a Bangladeshi schooling program on child immunization rates. The program provided a stipend and other incentives to attend secondary school, significantly increasing rural girls' education. I hypothesize that this would lead to higher immunization rates in the next generation since better-educated mothers have better knowledge of health practices. The study uses a regression model ("difference-in-differences"), which is based on differential exposure to the 1994 Female Secondary School Stipend Program (FSSSP) by birth cohort and rural residence. I find that the …

Quality Of Life Factors In Children With Dual Diagnosis Stuttering And Autism Spectrum Disorder, Kristen N. Rollins

USF Tampa Graduate Theses and Dissertations

Addressing quality of life is a critical part of speech-language pathology. Understanding quality of life deficits and challenges in our patients’ lives allows us to provide well-rounded treatment. Quality of life in children who stutter and children with autism spectrum disorder has been heavily researched (children with autism spectrum disorder to a lesser extent). However, despite approximately 1 in 1000 children being dually diagnosed with stuttering and autism spectrum disorder (Briley & Ellis, 2018), quality of life in this population has never been researched. This thesis aims to determine whether children diagnosed with both conditions experience similar quality of life …
