Supporting Cultural Capital In Undergraduate Biology: Instructor Roles And Practices, Lydia Nicole Mayo

Dissertations

Undergraduate biology students must navigate complex academic environments that require more than content mastery alone. Increasing evidence shows that students’ attitudes, beliefs, and values—such as motivation, confidence, and a sense of belonging—are critical to student engagement, persistence, and success, especially among first-generation college students and those from historically marginalized backgrounds. Therefore, the purpose of this dissertation is to use cultural capital theory to explore how instructor practices in college biology classrooms support these non-content resources, framed as three forms of cultural capital: aspirational, navigational, and emotional capital for college biology.

To investigate this phenomenon, the dissertation integrates three complementary studies. …

A Moderation Analysis Of The Relationships Between Burnout, Internalizing Symptoms, And Self-Care, Alexandra Mccorkle Ryan

Dissertations

Amidst growing awareness of burnout among school psychologists, self-care has been suggested as an essential practice for managing the emotionally and psychologically taxing elements of the job. Indeed, self-care has been included in the American Psychological Association’s list of professional competencies for health service psychologists (HSPs) in training. Mitigating burnout is an important objective, however, the current conceptualization of burnout as a problem that can be managed by an individual alone is inaccurate. Rather, burnout is a product of an occupational system in which job demands outweigh job resources. Furthermore, burnout can exacerbate symptoms of anxiety and depression. While self-care …

Undergraduate Faculty Experiences With Test Remediation, Shauna L. Haynes

Dissertations

Nursing students’ success in didactic courses generally depends on test scores. Students who fail to achieve a designated score might fail the test and/or the course. Test remediation is an intervention that could be implemented in response to a student’s failure. The intent of test remediation is to improve the student’s success on future exams and maximize the likelihood of progression. While remediation for success on the National Council Licensure Examination, standardized exams, and for the achievement of clinical skills were well documented, little research was found on test remediation for individual course exams. The purpose of this study was …

Through Their Eyes: A Photovoice Study Of Mental Health And Well-Being Among Rural-Dwelling Latina Adolescents, Ashley Marie Coburn

Dissertations

Latina adolescents are more prone to depressive symptoms, less likely to receive mental health services, and face higher rates of suicidality compared to their non-White peers. This population becomes more vulnerable to adverse outcomes when their problems are compounded by barriers to mental health care common in rural communities such as limited resources, stigmatization, and systemic inequities related to race/ethnicity, income, and insurance status. Despite Latinx youth representing the fastest growing racial or ethnic group in rural areas across the United States, there is limited research on the distinct factors shaping mental health outcomes for this population. Guided by an …

Integrating Diversity, Equity, And Inclusion Into An Undergraduate Sport And Exercise Science Program: A Holistic Case Study Utilizing Social Justice Education, Genevieve R. Altomare

Dissertations

It has been recommended by many scholars to integrate diversity, equity, and inclusion (DEI) content into higher education curricula across disciplines; however, several institutions have yet to do so. The ongoing discourse surrounding social justice continues to influence the careers of future professionals, especially in the fields of sport and exercise science. Yet, there remains a limited understanding of the perceptions and experiences of students who have participated in a college course centered on DEI topics. Therefore, the purpose of this holistic case study was to provide an in-depth examination of a newly developed DEI course by exploring the authentic …

Reinforcement Learning And Virtual Human Animation: A Novel Approach To Data-Driven Animation, Portraying Dynamic, Flexible Human-Like Behaviours, Vihanga Gamage

Dissertations

Virtual characters require animation capable of portraying dynamic, context-sensitive human-like behaviours. Several approaches to generating such animation have been developed, but each carries limitations. Motion capture can produce high-fidelity animation but is expensive and ill-suited to systems that must respond in real time. Physics-based reinforcement learning (RL) enables flexible, dynamic behaviour portrayal, yet relies on simulation feedback signals that are unavailable for social gestures. Supervised approaches can learn social behaviours from motion capture data but yield agents with limited flexibility and generalisation.

This thesis presents RLAnimate, a model-based, data-driven RL framework for character animation that enables a single agent to …

Investigating The Effects Of Drinking Environments On Alcohol Protective Behavioral Strategy Use, Perceived Self-Efficacy, And Perceived Effectiveness Through Experimental Vignette Design, Skyler Hoover

Dissertations

Derived from a Social Cognitive Theory framework (Bandura, 1986), the aim of this study was to assess the impact of different drinking environments on college students’ expected use of alcohol protective behavioral strategies, perceived effectiveness of those strategies, and perceived self-efficacy to use them. To accomplish this, we sought out to create and employ experimental vignettes consisting of a bar/club or party drinking environment in a two-part study. Study one aimed to pilot test the vignettes prior to their use in study two, whose aim was to test our initial hypotheses. Both analytic samples were recruited from a nationwide participant …

Test Driving Proximity Distances For Teacher Implementation Of Effective Instruction Delivery, Kenneth Joseph Ross Ii

Dissertations

Student noncompliance can disrupt teacher instruction and affect students’ ability to learn in the classroom. Interventions can be provided to teachers within the PBIS tiered system to address noncompliance. One intervention that addresses noncompliance, Effective Instruction Delivery (EID), has been demonstrated to increase levels of compliance above baseline levels. Despite the effectiveness of evidence-based interventions such as EID, there are significant concerns with ensuring the feasibility of evidence-based interventions to match the needs of teachers in the classroom to reduce teacher burn-out. A possible strategy to promote high levels of fidelity is to allow teachers to test drive interventions before …

The Impact Of A Multilingual Learner Professional Development On Teacher Self-Efficacy And Student Perceptions Of Teacher Support, Mark A. Bryan

Dissertations

The population of multilingual learners is struggling to adapt to mainstream classes because the educational system has failed to support them on the same level as native English speakers. The gap in achievement and lack of teacher preparation demonstrates a clear need to support teachers who educate them. This study, a nonequivalent (pretest and posttest) control-group design combined with a cross-sectional survey design, addressed the effectiveness of a professional development series focused on best practices for teaching secondary math to multilingual learners. The professional development intervention consisted of one 45-minute initial session followed by twelve 15-minute mini lessons throughout the …

Link Between Adverse Childhood Experiences And Parenting Styles Of African American Fathers, Tatianna P. Johnson

Dissertations

African American fathers may be more susceptible than fathers of other races to having a negative parenting style due to their high levels of adverse childhood experiences (ACEs). ACEs are traumatic experiences during childhood that can affect a person’s mental and physical health, income and adult parenting style. African American adults tend to have experienced multiple levels of ACEs at a higher rate than White and Asian adults (Maguire-Jack et al., 2021). ACEs can lead to adults experiencing higher levels of alcoholism, depression, health-related issues, mental illness, substance use, and academic problems. The purpose of this cross-sectional study was to …

How Was Rehab? A Follow-Up To A Randomized Effectiveness Control Trial Of A Brief Acceptance And Commitment Therapy Protocol For Inpatient Detoxification Patients, Alexander J. Twohy

Dissertations

Residential treatment for Substance Use Disorders (SUD) is a common treatment modality. However, the literature is sparse on modifiable predictors that affect change during the residential treatment stay. Acceptance and Commitment Therapy (ACT) has been shown to be an effective treatment for SUDs. Weststrate et al. (2023), in a randomized controlled effectiveness trial, compared ACT plus medication management to medication management during detoxification. The addition of ACT increased consumer satisfaction and ACT skills use, while decreasing psychological inflexibility and reducing withdrawal symptoms.

This study explored whether the brief ACT intervention had impacts during participants' subsequent residential stay. Forty out of …

Examination Of Caregiver Supervision Practices And Beliefs Among Caregivers Of Children With Bleeding Disorders, Sophia Noelle Prokos

Dissertations

Abstract: Unintentional injury is the leading cause of death for young children in the United States, and children with chronic medical conditions such as bleeding disorders are at elevated risk for injury and more severe outcomes (Centers for Disease Control and Prevention [CDC], 2021; Mayes et al., 2009; Shen et al., 2016). While caregiver supervision is a known strategy for injury prevention (Damashek & Corlis, 2017; Morrongiello et al., 2011), limited research has examined how supervision beliefs and practices differ for caregivers of children with bleeding disorders. The present study compared caregiver supervision, injury attitudes, and injury history between …

Parenting For Wellness: Positive Parenting Factors As Predictors Of College Student Physical Health, Mental Health, And Social Connectedness Through The Lens Of Self-Determination Theory, Mary E. Lamkin

Dissertations

Research suggests that the transition to college can impact college student well-being across the domains of physical health, mental health, and social connectedness (Frech, 2012; Pittman & Richmond, 2008; Xiao et al., 2017). As parents are more heavily connected to their college-aged students when compared to years before cell phones and social media, they likely continue to play a significant role in their child’s well-being, even while they are in college (Wartman & Savage, 2008). Therefore, the aim of this dissertation was to investigate positive parenting behaviors as predictors of wellness in college-aged participants using Self Determination Theory (Ryan & …

Framing The Problem To Meet The Policy Solution: An Embedded Mixed Methods Case Study Of The 2017 Michigan Opioid Laws, Leandra Hawkins Burke

Dissertations

The opioid crisis presents a wicked problem for public administration. Hundreds of thousands of people have died from opioid overdoses in the United States, and countless others have experienced severe opioid-related physical, psychological, and socioeconomic harms. Countering the opioid crisis has been difficult due to interdependencies across different drugs and multiple pathways for abuse and dependence. Many scholars, health providers, and politicians have called for a broad public health approach to combat the opioid crisis, but the full expanse of what that would entail has not yet been realized. What has been demonstrated is that interactions targeting a single aspect …

The Impact Of Feedback Timing On Work Performance When There Is A Long Duration Between Sessions, Priyanka B. Dave

Dissertations

Performance feedback is a powerful tool central to many functions at work, as it guides, motivates, and rewards employees’ behaviors. To better understand the function of feedback, previous research has examined the impact of feedback’s timing (proximal to the previous per-formance versus proximal to the next performance) on the effectiveness of feedback. However, the findings have been mixed across studies. Studies with less than 1-day between session dura-tions tend to find no difference between after-session versus before-session feedback. However, investigations with multiple-day between session durations tend to find improved performance with before-session feedback. This study used a counterbalanced across-subject design …

Multiple Monochromatic Subgraphs In Edge-Colored Graphs, Emma Felicity Jent

Dissertations

Ramsey theory, though a relatively young branch of mathematics, has captivated the attention of graph theorists, combinatorialists, and theoretical computer scientists alike through its raw beauty, versatility, and powerful applications. Before it emerged as a branch of mathematics, the central idea of Ramsey theory appeared in the form of three lemmas in three separate papers by three different mathematicians working on three distinct areas of research. The first such lemma was published by David Hilbert in 1892, followed by the second lemma published by Issai Schur in 1916. However, Frank Ramsey’s renowned lemma, published in 1930, compelled mathematicians to establish …

"It Can Be Hard To Stand Up Straight In A Crooked Room:" Examining The Mediating Effects Of Black Women's Gendered Racial Identity On The Relationship Between The Strong Black Woman/Superwoman Schema And Collective Coping, Devin Willis

Dissertations

Prior research on the Strong Black Woman (SBW)/Superwoman (SW) schema has produced mixed findings. Both positive and negative outcomes of Black women’s internalization of this schema have been identified. These mixed findings may be linked to the measurement of the SBW/SW schema and the relationship with other culturally relevant variables. There have been significant positive relationships identified between Black women’s gendered racial identity (GRID) and the internalization of gendered racial stereotypes (i.e., the SBW/SW). Methods for coping with stereotypes have also been identified as influential when considering Black women’s coping behaviors.

The purpose of this study is to examine the …

Mechanistic And Evolutionary Insights Into A Group Of Nicotine And Hydroxynicotine Degrading Flavoenzymes, Zhiyao Zhang

Dissertations

Flavoprotein amine oxidases (FAOs) are key enzymes in various kinds of metabolic pathways, mediating redox reactions via flavin cofactors. While most FAOs function as oxidases that readily reduce oxygen to hydrogen peroxide, a few outliers of the FAO family act as dehydrogenases that suppress the reaction with oxygen. The molecular basis for this divergence in function remains poorly understood.

The work presented in this study investigates the fundamental mechanisms of how flavincontaining enzymes activate or suppress their reaction with different electron acceptors to achieve high turnover rates. The overall body of work is divided into three different sections that (1) …

A Brief Cognitive-Behavioral Intervention For Emotion Regulationand Aggression In Justice-Involved Adolescents: Preliminary Outcomes From A Non-Randomized Trial In Short-Term Juvenile Detention, Cassidy L. Tennity

Dissertations

Justice-involved youth are at risk for a variety of psychosocial difficulties, including anger, aggression, and emotion regulation challenges. Short-term juvenile detention settings offer a unique opportunity to provide psychological interventions to youth before they are returned to the community or sentenced to long-term placements. However, implementation barriers within these settings often hinder the delivery of evidence-based care. This study developed and tested a brief, two-session anger management intervention for adolescents detained in a short-term juvenile detention center in the Southeastern United States, drawing on evidence-based practices from prior work with justice-involved youth. The present study examined implementation outcomes (i.e., feasibility, …

Human Resource Management And Black Teachers’ Employee Experience In K-12 Urban Public Schools, Danielle Renee Cooper-Williams

Dissertations

National teacher data indicate that publicly funded schools in the United States struggle to retain Black teachers in high-need urban areas and in comparison to other groups (Carver-Thomas & Darling Hammond, 2017). This qualitative investigation employed case study methodology. The case study focused on one school within a charter management organization (CMO), exploring interactions among Black teachers and their supervising administrators at the site and management organization levels. The study was organized around concepts articulated at the nexus of teacher retention scholarship and human resource management theory, two bodies of literature yet to be substantially integrated to understand Black teachers’ …

Population Dynamics Of Feral Hemp (Cannabis Sativa L.) Across Illinois, Bryan Scott Foster

Dissertations

Hemp (Cannabis sativa L.) is an historically cultivated species re-emerging in modern agriculture due to its utility as a fiber, grain, and cannabinoid crop. While industrial hemp refers to cultivated varieties bred for specific agronomic traits and legally defined by low tetrahydrocannabinol (THC) content, feral hemp, often called "ditch weed", represents escaped or naturalized populations descended from historical cultivation. These unmanaged populations persist and spread in disturbed habitats across North America, particularly in the Midwestern U.S., raising ecological and agronomic concerns due to their potential for genetic contamination, invasive behavior, and interactions with native species and agricultural systems. The overall …

One Step Closer To Greater Understanding! Does A Correlation Exist Between Fluid Intelligence And Player Rank In League Of Legends?, Evan Miller

Dissertations

Chess, one of the oldest modern games, has long been a model domain for expertise research. In comparison, research on video games has historically been influenced by moral panic. Cycles of moral panic tend to revolve around preconceived notions of threats, held at a societal level (typically by older generations). Politicians, quick to capitalize, then advocate for policy change based upon their constituents’ fears. Concurrent media reports draw further attention to the issue, amplifying the perception of harm. As the panic escalates, pressure is placed on scientific communities to perform confirmatory (not exploratory) research. This fundamentally biased approach to research …

A Monte Carlo Analysis Of Cost Competitiveness Of Chinese And U.S. Fine Chemical Exports To Europe Under Europe’S Energy Crisis, Lin Luo

Dissertations

The European energy crisis, driven by geopolitical conflicts, has created a significant supply-demand gap in Europe’s fine chemical sector, necessitating reliance on imports from the United States and China. This quantitative study examined how energy, labor, and logistics costs interacted to shape the cost competitiveness of U.S. and Chinese fine chemical exports to Europe, using a Monte Carlo simulation parameterized with historical data from 2015-2023, to provide a probabilistic forecast of competitive outcomes. The findings revealed that while China holds a 76.55% probability of being the lower-cost supplier, its advantage is characterized by high volatility primarily due to its logistics …
