Comorbidity And Violence: What Role Does Resilience Play In Preventing Violent Acts?, Madeline J. Petit

Theses and Dissertations

The conjunction of substance use disorders, mental illnesses, and violence has been shaped through traditional risk-centered models, yet these approaches fail to explain why most individuals do not engage in violent behavior despite being high risk. This study aims to investigate how resilience may buffer the criminogenic effects of comorbidity and help understand the majority of those at risk who remain nonviolent. The data for this study is drawn from the MacArthur Violence Risk Assessment Study, which consisted of 2.255 person-waves, as the data examined comorbidity across 5 waves, consisting of 451 participants in each wave.Each participant in each wave …

The Role Of Body Composition In Predicting Fitness Performance Of Law Enforcement Officers, Taylor J. Parmentier

Theses and Dissertations

Law enforcement officers (LEOs) perform physically demanding tasks such as foot pursuits, lifting, carrying, dragging, and physical restraint. Effectively performing these duties requires significant muscular strength, endurance, and cardiorespiratory fitness. Lower fitness levels pose risks for reduced health, performance, slower recovery, increased fatigue, and potentially affecting decision-making under strenuous conditions. The purpose of this study was to identify the strongest predictor of physical fitness performance among active-duty LEOs. Body composition analysis and a comprehensive fitness evaluation of twenty-nine male LEOs (age: 36.2 ± 9.3 years, body mass (BM): 95 ± 13.7 kg, height: 1.8 ± 0.1 m) was completed. The …

An Application Of Molecular Dynamics To Hed Plasma Physics: Point And Group Defect Diffusion In Coulomb Crystals, Levi Webb

Theses and Dissertations

Molecular dynamics (MD) simulations are used to explore the microscopic behaviors of complex systems that cannot be easily studied experimentally. In particular, the microphysics of high energy density (HED) astrophysical plasma environments remain inaccessible by modern experiment---even in laser facilities, these plasmas exist only on short timescales that do not lend easily to investigation. The diffusion of point and group defects through crystallized plasmas in the cores of white dwarfs and neutron star crusts, called Coulomb crystals, has potentially macroscopic implications for the evolution of these bodies. Thus, I employ the widely-used MD code LAMMPS to simulate small Coulomb crystal …

Informing Policies: Examining Socio-Cultural Factors Influencing The Prevalence Of Gender-Based Violence, Patricia M. Ebubechukwu

Theses and Dissertations

Despite growing policy attention and legal reforms, Intimate partner violence (IPV) remains a persistent public health and human rights concern in Nigeria. This study examines the socio-cultural influences on the prevalence of gender-based violence among ever-married women in Nigeria using data from the 2024 Nigeria Demographic and Health Survey (NDHS). Drawing on a nationally representative sample of 19,863 women aged 15 to 49, the research investigates how geopolitical zone, internalized gender norms, religious affiliation, educational attainment, and household wealth shape women’s experiences of physical, sexual, and emotional IPV. Guided by social norms theory and the ecological model of violence, the …

Managing Multi-Drug Resistance: An Evolutionary Game Theory And Optimal Control Approach, Shukhrat Nasrulloev

Theses and Dissertations

Multi-drug resistance is an evolutionary process in which treatment eliminates sensitive cells, allowing resistant clones to dominate. This thesis investigates this process using a framework integrating population dynamics, evolutionary game theory, and optimal control theory. We develop a two-population logistic growth model describing competition between drug-sensitive and drug-resistant cells under treatment, construct dose-dependent payoff matrices and replicator dynamics to characterize evolutionary competition, and derive a critical drug level D_crit = (r_S - rR)/(dS - d_R) at which resistant cells gain a fitness advantage. An optimal control problem is formulated via Pontryagin's Maximum Principle to identify schedules …

Perceived Barriers To Physical Activity And Campus Recreation Facility Usage In College Students Referred Or Not Referred To An Exercise Is Medicine® On Campus Program, Benjamin M. Colbert

Theses and Dissertations

INTRODUCTION: Approximately 36-50% of college students are inactive and report numerous barriers to being physically active. Physical activity (PA) barriers are any obstacle an individual believes affects their PA participation. Individuals who perceive more barriers are less likely to participate in PA and as such, interventions that target barriers may increase PA participation. Exercise is Medicine^® on Campus (EIM-OC) is one intervention that may improve PA levels on college campuses by reducing barriers. The purpose of this study was to document PA and campus recreation facility barriers in university students and examine the influence of an individualized EIM-OC intervention …

Theses and Dissertations

This study examines the causal Impact of sports gambling legalization on marital stability in the United States using data from the Current Population Survey Annual Social and Economic Supplement (CPS-ASEC) and the American Community Survey (ACS) from 2013 to 2024. The analysis leverages variation in the staggered adoption of state-level sports gambling laws and applies two-way fixed effects, event-study, and the Callaway and Sant’Anna (2021) difference-in-differences estimators, controlling for geographic and individual characteristics. Legalization increases divorce rates by 0.42 percentage points in the CPS and 0.51 percentage points in the ACS, corresponding to increases of 2.4% and 2.6%, or approximately …

Enhancing Hospital Length Of Stay Using Ai Agent Modular Capabilities, Dami Fred

Theses and Dissertations

Hospital Length of Stay (LOS) analysis is essential for managing hospital efficiency and financial performance, yet the analytical depth required remains inaccessible to many organizations due to technical and resource constraints. This thesis introduces the AI Agent Modular Capabilities (AIAM) framework, which decomposes LOS analysis into discrete, codifiable capabilities integrated into a single skill activatable with one prompt. Seven AI Agent Modular Capabilities were developed using a Work Breakdown Structure and tested against a simulated hospital scenario across three successive skill versions. Results demonstrate that the packaged AIAM skill produces comprehensive, consistent, multi-section LOS analyses from a single interaction, outperforming …

Sibling Relationships Within The Context Of Chronic Conditions, Megan M. Sulak

Theses and Dissertations

This investigation explored how siblings and caregivers experience family life when one or more children have a chronic condition, with specific attention to examining what promotes connection, bonadaptation, and resilience among sibling pairs. Interviews with 10 members of 4 families contributed to the development of a grounded theory whose core theme centered on how knowledge often drove sibling relationship quality.  When individuals with chronic conditions, along with their siblings and parents, were able to access accurate knowledge and understanding about their condition, how to navigate fluctuations in health or illness, and the health care system, they reported being better able …

Built Different: Place, Identity, And The Holistic Well-Being Of Female Student Athletes, Jaye Mack

Theses and Dissertations

This research furthers the conversation surrounding holistic female student-athlete wellness, recognizing that their experiences can be inequitable – influenced by the intersectionality of race, gender, and athletic identity (Armstrong et al., 2018; Druckman et al., 2018; Neeley et al., 2021). This research accredits the physical environments where athletes train, recover, and connect as an underexplored factor in holistic well-being.

The Indivisible Self Model of Wellness (IS-WEL) was used to (1) explore the influence of physical design features on female student athletes' holistic well-being and (2) understand how their identity shapes how they experience and attach meaning to their team environments. …

Framing Belonging And Exclusion: A Dialogic Narrative Analysis Of English- And Spanish-Language Immigration Coverage During The Trump 2024 Presidential Election, Evangeline T. Cruz

Theses and Dissertations

I investigated how English- and Spanish-language news outlets narratively constructed Latinx immigrants during the Trump 2024 presidential campaign, a period marked by heightened anti-immigrant rhetoric and political volatility. While past scholarships examined immigration framing through tone, sentiment, or frequency analysis, limited attention has been given to the deeper narrative structures that shape public meaning-making. This study addresses this gap by applying Dialogic Narrative Analysis (DNA) and Critical Thematic Analysis (CTA) to a bilingual dataset of 120 newspaper articles from The New York Times, Los Angeles Times, El Diario, and La Opinión published between November 2024 and February 2025.

Findings reveal …

Cover Crop Effects On Soil Porewater Nutrients And Hydrothermal Properties, Md Mahadi Hasan

Theses and Dissertations

Adoption of winter cover crops in the U.S. Midwest may reduce nitrogen (N) and phosphorus (P) leaching from soils, potentially shrinking the hypoxic zone by limiting nutrient runoff into the Gulf of Mexico. To evaluate the impact of selected winter cover crops on soil porewater N and P concentration, a field study was conducted at the Illinois State University Research Farm (ISURF) and the Western Illinois University Research Farm (WIURF). The experimental design was a block experiment with four replications.  Cover crop treatments included a winter fallow, wild pennycress (WPC), golden pennycress (GPC), cereal rye (CR), annual ryegrass (AR), and …

Type Ii Diabetes Treatment Comparison Via Compartment Modeling, Abigail M. Collins

Theses and Dissertations

Type II diabetes mellitus affects one in ten adults worldwide, yet the effects of treatment type and adherence level on developing complications and quality of life have not been well characterized at the population level, and mathematical modeling offers a structured way to examine these dynamics. This thesis adapts the Boutayeb et al. (2004) model to incorporate dynamic treatment types and levels of adherence, producing nine scenarios in which complication development rate and complication recovery rate differed, to compare peak complications and quality of life across treatment and adherence conditions. Using a system of ordinary differential equations and compartment modeling, …

From Deference To Dialogue: How International Gtas From High Power Distance Cultures Adapt To U.S. Classroom Dynamics, Deborah Akua Afi Appiah

Theses and Dissertations

International graduate teaching assistants (GTAs) from high power distance cultures play a significant role in undergraduate education at U.S. universities, yet they face challenges that go well beyond language proficiency. Coming from educational backgrounds where teacher authority is unquestioned and hierarchical, these GTAs must navigate American classrooms that operate on fundamentally different assumptions, where authority is earned rather than assumed, informality is the norm, and students expect to question, negotiate, and be personally known by their instructors. The present study examined how eighteen (18) international GTAs from seven (7) high power distance countries perceived and adapted to these differences while …

“Is This Really Funny?” Humor, Rape Myths, And Social Semiotics In Nigerian Comedy Skits, Grace Oluwatofunmi Adeyemo

Theses and Dissertations

This study examines how rape myth narratives are normalized through humor in Nigerian comedy skits. While existing research has identified rape-supportive beliefs in digital entertainment, it has paid less attention to the processes through which these meanings become socially acceptable. Guided by social semiotics, the study analyzes how semiotic resources use humor to normalize rape myth narratives in Nigerian comedy skits. Using a qualitative design, twelve purposively selected Nigerian comedy skits on YouTube were analyzed. The findings reveal that refusal is constructed as temporary, persistence is portrayed as effort, men's refusal is framed as abnormal, and consent is shaped by …

Thinking Machines: Cybernetics, Artificial Intelligence, And Technological Anxiety In The American Cold War, Erin Mae Wilcox

Theses and Dissertations

Following the Second World War, cybernetics emerged as a cross-disciplinary study in philosophy, neurophysiology, electrical engineering, and mathematics. Cyberneticists proposed the formal study of the man-machine analogy; that is, to equate biological structures to a complex mechanical system. Drawing from this analogy, cyberneticists used programmable digital computers to emulate the functions of the human brain. The study of artificial intelligence emerged within this cybernetic discourse in the early 1950s; yet, by the mid-1960s, the two disciplines suffered a methodological fracture. Drawing from a tradition generated by this fracture, historians have traditionally examined cybernetics and artificial intelligence in isolation from one …

Secret-Keeping Experiences Of Young Adults, Jace C. Griffith

Theses and Dissertations

In 2020, researchers Frijns et al. called for a new wave of secret-keeping research which prioritized the person-centric experience of youth keeping secrets. This study added to that collection by comparing two kinds of secret-keeping which are not compared in existing research: secrets which are related to abuse, and secrets which are not. Researchers in the field of child welfare study only abuse-related secret-keeping, almost always qualitatively. Alternatively, researchers of non-abuse secret-keeping or general secret-keeping collect almost entirely quantitative data, absent of the personal experience of secret-keeping.

Through an online survey, 205 undergraduate students were asked to reflect on an …

Social Media, Masculine Body Ideals, And The Drive For Muscularity: A Serial Mediation Model Across Sexual Identities, Sean P. Mcdaniel

Theses and Dissertations

Body image concerns among men are increasingly prevalent yet remain understudied compared to women’s experiences. Drawing on objectification theory, the present study examines the relationship between social media influence and men’s drive for muscularity through a serial mediation model. Specifically, the present study investigates whether the internalization of masculine body ideals and engagement in body surveillance behaviors mediate the link between social media influence and the drive for muscularity. Furthermore, the present study model attempts to explore how these processes differ across sexual identities, given evidence that sexual minority men face distinct sociocultural pressures regarding appearance. Adult male-identifying social media …

However, continued research is needed to better understand how family-centered programs support both Latine youths’ sense of belonging and their perceived preparedness for college. This study focuses on how participation in the Juntos Para Una Mejor Educación program relates to Latine youths’ sense of belonging and perceived preparedness for college, as well as how family expectations shape these outcomes. …

Between Tradition And Transition: Cultural Negotiations And Contraceptive Perceptions Among Ghanaian Students In The United States, Beatrice Amissah

Theses and Dissertations

As global mobility continues to rise, international students often encounter new cultural norms and health practices that differ from those in their home countries. While some studies have focused on contraception within the context of gender and types, less focus has been placed on diasporic populations, especially how students navigate tensions surrounding contraception within new cultural environments. This study explores how Ghanaian students in the United States interpret, negotiate, and respond to contraceptive messaging while navigating the cultural transition between their heritage and host societies. Drawing on Berry’s (1980)  Acculturation Theory, the study examines the tensions students experience, the strategies …

Fostering A Growth Mindset In Mathematics: Faculty And Student Experiences, Yolanda G. Rush

Theses and Dissertations

According to the Center for Community College Student Engagement (2019), many students attending two-year institutions need productive persistence strategies, including the development of a growth mindset. Although some growth mindset interventions have been effective in improving academic achievement among students (Boaler, 2016; Canning et al., 2024) and persistence (Lewis, 2019) among students, especially those with developmental needs (Suh et al., 2019) and those in mathematics, little is known about the experiences of students and teachers (i.e., students’ perceptions of teachers’ intentions and implementation) as teachers work to foster a growth mindset culture (Murphy et al., 2021). In this dissertation, I …

The Role Of Non-Academic Staff In First-Year Retention At Regional, Comprehensive Universities, Marco A. Krcatovich Ii

Theses and Dissertations

Regional comprehensive universities (RCUs) serve a large share of U.S. undergraduates, yet the role of non‑academic staff in shaping first‑year retention remains understudied. This dissertation examines how staff diversity and staffing structures relate to student persistence using seven years of IPEDS panel data and Linear Mixed‑Effects Models. Analyses were conducted separately for residential and commuter RCUs to reflect their distinct engagement environments. Findings show that staff diversity is significantly associated with retention, though the direction and magnitude vary by campus type and staff role. Staffing structure also matters as higher proportions of full‑time staff are positively associated with retention at …

Staff Attitudes Toward Ai Adoption At A Private Research University, Ashley C. Smith

Theses and Dissertations

This study addresses the limited research on university staff attitudes toward artificial intelligence use and adoption. Using the Unified Theory of Acceptance and Use of Technology (UTAUT) research framework, the General Attitudes towards Artificial Intelligence Scale (GAAIS), and quantitative survey methodology, the study examines the attitudes of higher education staff toward AI, specifically examining whether demographic or professional characteristics are factors. The findings indicate that staff had moderately negative attitudes toward AI while also expressing some concerns. The results suggest that more resources and support for AI are needed for staff to address concerns. It also suggests that construct-level analysis …

Refusing To Die On The Vine: Black Women's Survival, Resistance, And Dei Labor In Historically White Institutions, Senesta D. Howard

Theses and Dissertations

This dissertation examines the lived experiences of Black women in non-diversity, non-faculty roles at historically White institutions (HWIs) who engage in diversity, equity, and inclusion (DEI) advocacy beyond their formal job responsibilities. Grounded in Black Feminist Thought and guided by Interpretative Phenomenological Analysis, the study explores how race and gender shape invisible labor expectations, emotional and psychological burdens, and strategies for safety and meaning-making. Semi-structured interviews with 12 Black women staff members yielded seven interrelated themes, including invisible DEI labor, hypervisibility, emotional exhaustion, sisterhood as a form of resistance, respectability politics, self-constructed safety, and purpose rooted in legacy and spirituality. …

Constructing And Deconstructing Homelessness: Challenging The Stigmatization Of The Unhoused Through Lived Experience, Brenna Jones

Theses and Dissertations

As homelessness rises across the United States, public discourse plays an important role in shaping how the housing crisis is understood and addressed. This study examines how homelessness is constructed through local media narratives and how these constructions shape the experiences of unhoused individuals. Using a case study of Greater Bangor, Maine, this research combines a critical content analysis of 315 news articles from the Bangor Daily News (2020-2025) with in-depth interviews with 18 unhoused and precariously housed individuals. The findings demonstrate how media portrayals construct homelessness as a stigmatized identity associated with disorder, addiction, and danger. These narratives contribute …

Performance-Based Funding’S Influence On Higher Education Through The Eyes Of Department Chairs, Jonathan W. Lackland

Theses and Dissertations

Performance-based funding (PBF) has become a widely adopted policy in higher education, linking state appropriations to measurable outcomes such as graduation rates, degree completions, and workforce alignment. While PBF aims to enhance institutional accountability and efficiency, its implementation has raised significant concerns about equity and political influence. This dissertation examines the political equity and implications of PBF policies through a mixed-methods approach, including surveys, interviews with department chairs, and critical discourse analysis of state statutes and legislative debates. The findings reveal that PBF often exacerbates inequities, particularly for non-flagship universities serving diverse and under-resourced student populations. Department chairs expressed concerns …
