Coming To The Table: How Black Mamas Resist And Reorganize The Racialized Educational Terrain In Community, Moriah Lynn Johnson

Dissertations

Black homeschooling has grown significantly among African American families, yet existing scholarship has not fully theorized how race, gender, and institutional power operate within homeschooling communities. My dissertation examines how Black mothers resist and reorganize a racialized educational terrain that extends beyond conventional schooling into homeschooling spaces. Drawing on Diamond’s (2006) racialized educational terrain framework, I introduce the Racialized Homeschooling Terrain (RHT) — an original conceptual framework that demonstrates how homeschooling spaces are racialized in similar and distinct ways. This framework centers Black maternal agency, as moms interpret, resist, and reorganize homeschooling spaces to construct communal homeplace. Using a qualitative, …

A Qualitative Study Of Gratitude Practice Among Won Buddhist Older Adults And Implications For Gerontological Social Work, Sungsim Lee

Dissertations

Although gratitude has been widely studied in social science, existing scholarship has largely relied on Western worldviews and quantitative research frameworks, limiting understanding of lived gratitude experiences within diverse spiritual and cultural contexts, including Eastern spiritual traditions. In Won Buddhism, originating in South Korea, gratitude holds a central place in spiritual life and is understood as an essential practice. This qualitative study explores the views of Won Buddhist older adult practitioners regarding their experiences, benefits, and challenges of engaging in spiritually grounded gratitude practice. Semi-structured interviews were conducted with 23 practitioners aged 65 and older from English-speaking Won Buddhist communities. …

Responsive Rigor And Strategic Care: Faculty Praxis For Holistic Student Success In The Community College, Jennifer Elizabeth Kelley

Dissertations

This qualitative study examines how community college faculty conceptualize, communicate, and enact academic rigor and care in their teaching practice. While post-pandemic debates have positioned rigor and care as opposing forces—evident in the "Rigor Wars" that framed care as performative laxity and rigor as gatekeeping—community college faculty successfully integrate these practices to support holistic student success. This research addresses critical gaps in higher education scholarship, which has studied rigor and care separately, focused primarily on four-year institutions, and overlooked faculty perspectives on how integration occurs in practice. Drawing on a single-case study of 38 faculty members at a large Midwestern …

Making Sense Of The Barrio: Place-Based Appraisal And Coping Among Latine Residents In Chicago, Juanita Vivas Bastidas

Dissertations

Residents of Chicago’s Latine barrios often describe their neighborhoods as places of familiarity and safety—sites defined by both personal independence and collective solidarity, where daily life is marked by a sense of belonging and mutual support. Yet, residents also contend daily with overlapping social and environmental stressors. While urban, medical, and environmental sociologists have each shown that place matters, their findings remain siloed and rarely integrated to illuminate the everyday realities of Latine neighborhoods. As a result, we lack a systematic analysis of how people living in Chicago’s Latine barrios make sense of and cope with multiple, simultaneous stressors. I …

Don't Force Me To Explain: Rethinking Access Outside Of Compulsory Transparency, Rhea Ienni

Dissertations

My dissertation is concerned with better understanding the barriers disabled people encounter while attempting to procure access both at the institutional level, and in their everyday lives. Within disability and accessibility literature, there are many discourses on what disability is and what access means. However, there are few people who explore the harmful consequences of disabled people being forced to “prove” they are disabled to an ableist world to get their basic needs met, and my dissertation intervenes in this gap. Within current US policy, if a disabled person requires access support at the institutional level, they must provide medical …

Diagnostic assessments, belonging surveys, and academic performance measures were used across multiple instructional phases. The study also explored the implementation of assistant-centered peer interventions model, targeted math reviews, and motivational starts designed to support student engagement and belonging. Findings suggested meaningful relationships among belonging, confidence, and academic performance, while highlighting the importance of supportive instructional …

Being Desi At School: Exploring The Racialized School Experiences Of South Asian American Youth, Prabha Kaundinya

Dissertations

Schools in America have been central areas for racialization, and as an immigrant, racial-ethnic minority population, South Asian American (SAA) students have been subjected to a variety of racialization processes (S. J. Lee et al., 2017; Rice, 2017, 2019; Subedi, 2013). However, what is known about SAA educational experiences is often based on celebratory stereotypes that proclaim their uniform success while neglecting attention towards the diversity of their needs (including academic, social-emotional, or mental health needs; Saran, 2015; Ngo & Lee, 2007; P. Patel & Patel, 2017; Pedraza & Guillaume, 2023; N. Sharma et al., 2020). This dissertation uses a …

Elucidating The Mechanisms Of Complex Flavoprotein Dehydrogenases, Tyler Alt

Dissertations

Flavins are ubiquitous redox active cofactors that can catalyze electron transfer between substrates. They offer the advantage of being able to stabilize a range of oxidation and protonation states, as well being amenable to covalent modification, which can further alter their activity. As such, the scope of reactions catalyzed by flavoproteins is broad and flavin has implications in a range of biological processes. The two predominant forms of flavin that serve as redox active cofactors are flavin adenine mononucleotide (FMN) and flavin adenine dinucleotide (FAD), which are functionally homologous. A major complication of studying flavoprotein dehydrogenases, and one that has …

The Year Of Birth Age Grouping Policy: Its Impact On Participation In Us Youth Soccer, Murray James Findlay

Dissertations

In 2016, the United States Soccer Federation (USSF) implemented a nationwide year-of-birth (YOB) age grouping policy that aligned youth soccer teams with calendar years (January 1st –December 31st), replacing the traditional schoolyear (August 1st –July 31st) grouping system. This dissertation investigates the impact of that policy on youth soccer participation in the United States, addressing a critical gap in empirical research linking national policy interventions to participation outcomes. Framed through the Fun Integration Theory (FIT) (Visek et al., 2015), which conceptualizes youth sport engagement as driven by social and intrinsic enjoyment factors, the study examines whether the YOB policy caused …

Merleau-Ponty On The Crisis Of Natural Philosophy: A Critique Of The Metaphysical Foundations Of Natural Science And Investigations Into The Ontology Of Nature, Kevin Mager

Dissertations

In this dissertation, I show that Merleau-Ponty’s philosophy of nature is also a radical critique of the metaphysical foundations of natural science. This critique leads us to a new ontology for science, grounded in the lifeworld. I focus on how his philosophy offers a detailed critique of both physicalism and mechanism. For Merleau-Ponty, mechanism is not just the strict adherence to classical causality, but any view that asserts that classical causality has any role to play in reality at all. To replace mechanistic causality, Merleau-Ponty argues that we must conceive of nature as grounded in meaningful possibility. Merleau-Ponty's emphasis on …

Uncovering Dkk1 As A Therapeutically Relevant Target In Aggressive Er+ Breast Cancer Using A Novel Antiestrogen, Kristen Young

Dissertations

Over 70 percent of breast cancers are estrogen receptor-positive (ERα+), meaning that the hormone estrogen drives tumor growth. Although first-line targeted therapies that directly block ERα from hormone-dependent pathologies are initially effective, almost half of patients ultimately progress. These patients show high mutational rates to the ESR1 gene that encodes for ERα. A hotspot missense tyrosine to serine mutation at position 537 (Y537S) initiates hormone-independent, allele-specific transcriptional programs that increase metastasis. While next-generation ERα-targeted therapies show promise, benefits are often limited compared to standard-of-care. Understanding the mechanisms of action used by the Y537S ESR1 breast cancer cells to evade therapeutic …

Jesus-Centered Preaching: A Christocentric Approach Based On The Hermeneutical Implications Of The Gospels As Βίοι., Mark Palmer

Dissertations

The purpose of this study was to discover the implied hermeneutic of the Gospels as βίοι and to propose a congruent homiletic. The study addressed the following research questions: What is the genre of the Gospels and the resulting hermeneutic? Does current Christ-centered preaching account for his hermeneutic? Does Christological research account for intrinsic characteristics? What is the intrinsic Christology of Mark’s Gospel? What homiletical process is needed to align with the genre-based hermeneutic of the Gospels? The methodology of this study followed a four-step process: Genre research confirming the Gospels as βίοι, Christological research including the development of an …

Strategies For Extending The Service Life Of Prestressed Concrete I-Shaped Beams, Sanjoy Kumar Bhowmik

Dissertations

Prestressed concrete (PSC) I-shaped beams are widely used in bridge construction because of their structural efficiency and durability. The service life of these beams is reduced and the maintenance frequency is increased due to the distress during fabrication and subsequent deterioration. Although several mitigation strategies have been proposed and implemented, beam end cracking during fabrication remains a major concern. The causes and mitigation strategies for beam end cracking have been studied for decades, but there have been no comprehensive studies utilizing beam end strains during fabrication and lifting at prefabrication plants under normal operational conditions. Moreover, existing maintenance and repair …

An Attachment Perspective For Help-Seeking Intentions Among Emerging Adult Women Child Sexual Abuse Survivors, Dominique Giroux

Dissertations

Child sexual abuse (CSA) is an adverse childhood experience and a global health issue. Approximately one in four girls encounter CSA per year. Research evidence suggests approximately 50% of CSA survivors encounter sexual revictimization during adulthood (Walker & Wamser-Nanney, 2023), but formal help and intervention can mitigate further psychosocial harm experienced by CSA survivors (Widom et al., 2008). Attachment theory has provided a theoretical framework for identifying individuals at risk for revictimization and help-seeking patterns, such that individuals who have insecure attachment styles report more revictimization frequency, but the literature is mixed about attachment styles and help-seeking (Brenner et al., …

Deployment-Aware Deep Learning For Computer Vision: Efficient Architectures From 3d Segmentation To Mixed Reality, Bahar Uddin Mahmud

Dissertations

Deep learning has become the dominant approach for solving vision-centric problems; however, its successful deployment in real-world applications remains limited by high computational cost, data dependency, and insufficient integration with practical and human-centered environments. While state-of-the art deep learning models often achieve impressive performance in controlled settings, they frequently fail to generalize or operate efficiently under deployment constraints such as limited resources, complex data modalities, and real-time interaction requirements. These limitations motivate the need for a deployment-oriented deep learning framework that balances accuracy, efficiency, and practical usability.

This dissertation investigates the design and deployment of efficient deep learning architectures for …

Enhancing Postsecondary Outcomes For Students With Emotional And Behavioral Disorders: A Design-Based Mixed Methods Approach To Transition Planning, Kate M. Schrum

Dissertations

Students with emotional and behavioral disorders (EBD) experienced significantly lower postsecondary outcomes when compared to same-aged peers. These outcomes included lower graduation rates, higher unemployment rates, and difficulty establishing independent living arrangements (Wagner & Newman, 2015). Following a human-centered, design-based approach, the scholar-practitioner found a lack of consistent and meaningful transition support specifically designed for students with EBD. Working with a stakeholder team of educational professionals directly involved in supporting transition for students with EBD at an alternative special education program, the scholar-practitioner developed a "Transition Toolkit". The toolkit contained scaffolded grade-level checklists (for grades 6–12) with self-advocacy and goal-setting …

Using Design Thinking To Support Teacher Confidence In Delivering Culturally Relevant Literacy Instruction To Address Literacy Achievement Gaps, Amy Winters

Dissertations

Despite comprehensive efforts over the years, literacy rates in the United States continued to decline, particularly among students from disadvantaged populations. The literacy achievement gap was driven by socioeconomic disparities, inadequate teacher preparation, and a lack of access to evidence-based, culturally relevant materials. In the Main School District (MSD), the scholar practitioner identified while interventions existed, inconsistencies in literacy instruction and a lack of teacher confidence in delivering culturally responsive instruction hindered student progress. The dissertation in practice focused on addressing issues in literacy instruction and achievement while highlighting ways to meet teachers’ needs and provide means to engage all …

Navigating Future Careers And Life Purpose: The Effect Of Artificial Intelligence Experiences On Undergraduate Students At A Liberal Arts College, Shannon Kelly Schans

Dissertations

This interpretive phenomenological analysis examines how 13 undergraduate students at a liberal arts college construct meaning from their experiences with artificial intelligence technologies in relation to their career development and life purpose. Guided by an integrated theoretical framework combining Career Construction Theory (Savickas, 2012, 2013) and Transformative Learning Theory (Mezirow, 1991, 2000), the study addresses three research questions: how students describe their AI experiences across educational contexts, what connections they make between those experiences and their developing professional identities, and how they integrate AI experiences into broader narratives about work and purpose.

Data are collected through phenomenological interviews with 13 …

Enhancing The Metacognitive Thinking Of Middle-Grade Multilingual Learners: A Design-Based Research Study Leveraging Dialogic Teaching, Renee R. Burns

Dissertations

This study explores how dialogic teaching can enhance metacognition and self-efficacy among middle school multilingual learners (MLs) who face challenges with the academic language demands of literacy tasks. Using a design-based research (DBR) methodology, specifically formative experiment, the Metacognitive Dialogic Teaching Protocol (MDTP) was implemented over seven iterative cycles. The research questions were as follows: How do dialogic interactions impact metacognition in middle-grade MLs? How does Metacognitive Dialogic Teaching affect comprehension development in these students? And how does it influence their self-efficacy? The participants included six middle-grade MLs engaged in a Tier 2 literacy intervention who initially exhibited fake reading …

Attachment Style, The Working Alliance, And Client Self-Disclosure In Individual Psychotherapy, Jennifer S. Baar

Dissertations

Client self-disclosure is a core component of the psychotherapy process and increased levels of client self-disclosure have been shown to predict more positive therapeutic outcomes (Pattee & Farber, 2008; Sloan & Kahn, 2005). Similarly, the working alliance and attachment are constructs that have been studied in psychotherapy research and are consistently associated with therapeutic outcomes. Specifically, stronger working alliance ratings and higher levels of secure attachment have been found to predict more positive therapy outcomes (e.g., Flückiger et al., 2018; Mallinckrodt et al., 2005; Sauer et al., 2010). As these three constructs have been found to influence psychotherapy outcomes, the …

Exploring How Therapist Trainees’ Mentalization, Attachment Styles, And The Working Alliance Impact Treatment Outcomes In Psychotherapy, Hanali Gilbert

Dissertations

A burgeoning area of research within the past 30 years has sought to identify which specific therapist factors contribute to differential treatment outcomes (Barkham et al., 2017). The purpose of the current naturalistic study was to explore how two personal characteristics of therapist trainees, mentalization capacity and attachment styles, impact early treatment outcomes at two Midwestern psychology training clinics. This study also examined whether therapist mentalization and the working alliance interacted to influence client outcomes. Therapists completed the Mentalization Scale (MentS; Dimitrijević et al., 2018) and the Experiences in Close Relationships scale (ECR; Brennan et al., 1998), while the Working …

Evaluation Associations As Catalysts For The Professionalization Of Evaluation Practice: A Comparative Case Study Of Brazil, Ghana, Indonesia And Uganda, Amy C. Jersild

Dissertations

Professional associations are recognized as key actors in promoting the development of the evaluation field across the globe. There has been exponential growth of Voluntary Organizations for the Professionalization of Evaluation (VOPEs) in the Global South in the past several decades in response to an evolving international aid agenda and a mobilized international evaluation field intent on supporting the development of national monitoring and evaluation systems and the professionalization of the field. VOPEs have featured as a central actor in the Global Evaluation Agenda, an initiative developed by the international community aimed to promote professionalization of the evaluation field as …

Reduced Product Type Monoid-Module Extensions, Darryl Jent

Dissertations

In 1955, I. M. James introduced the James Construction, a free topological monoid that models the loops on the suspension of a given space. In 1969, S. Y. Husseini generalized this idea to RPT monoids: topological monoids with a free-like monoid structure that can be used to model a broader class of loop spaces. In order to prove that these topological monoids are models of loop spaces, both I. M. James and S. Y. Husseini constructed contractible spaces on which these topological monoids act. We define a topological module as a space equipped with an action by a topological monoid. …

From Total Domination To Graph Coloring, Sawyer Isaac Osborn

Dissertations

A question involving a chess piece called a prince on the 8×8 chessboard leads to a concept in graph theory involving total domination. We say a vertex u in a graph G totally dominates a vertex v if u is adjacent to v. A subset S of the vertex set of a graph G is a total dominating set for G if every vertex in G is totally dominated by at least one vertex of S. If S is a total dominating set of G, then σ_S(v) denotes the number of …

Personal And High-Intensity Gait Factors Associated With Balance And Walking Improvement With Outpatient Stroke Rehabilitation: A Retrospective Study, Heather Staal

Dissertations

Objective: The purpose of this study is to examine the relationships between personal factors and High-Intensity Gait variables and balance and walking improvement in an outpatient stroke population.

Background: Stroke is a leading cause of long-term disability, with persistent gait and balance impairments commonly limiting independence and participation. High-intensity gait training (HIGT) is an evidence-based rehabilitation approach that improves walking outcomes following stroke; however, guidance on how specific training variables are applied in outpatient physical therapy settings remains broad.

Methods: This retrospective observational study analyzes clinical data from outpatient physical therapy episodes in which HIGT is a …

Predicting Clinical Outcomes Of Non-Specific Low Back Pain By Studying The Interaction Of Clinical And Demographic Factors Of A Retrospective Data Set, Erica Michelle Fernandes

Dissertations

The purpose of this research is to investigate demographic factors, including age, gender, body mass index (BMI), race, marital status, insurance type, severity of disease (initial pain level), and clinical factors such as number of visits (no. of visits) at physical therapy (PT), length of time at PT and the type of clinician either physical therapist versus physical therapy assistant (PTA), that most predict PT clinical outcomes in patients with nonspecific low back pain (NSLBP) and see if there is an interaction between demographic and clinical variables.

Methods

The current study is a retrospective, cross-sectional, observational study using secondary electronic …

Campus Community Vibes: How Queer Asian American Students Navigate Their Higher Education Experiences, Nathan Nguyễn

Dissertations

Misconceptions and stereotypes about Asian American college students include the belief that they are innately academically successful and that if Asian American students struggle, their challenges do not compare to their Black/African American, Hispanic/Latine, or Native American/Indigenous counterparts (Museus & Buenavista, 2016). Contemporaneous to this, lesbian, gay, bisexual, transgender, and queer (LGBTQ) college students experience interrogation, exploration, and various levels of support regarding their sexuality and/or gender identity. At this intersection, queer Asian American students must navigate campus settings that can enhance or diminish their agency for different facets of their identities (Crenshaw, 1991; Iftikar & Museus, 2018; Ray, 2019). …

Long-Covid And Cognition, Mychael Bruce

Dissertations

COVID-19 is an evolving virus that can harm the body’s respiratory and cardiovascular systems. Directly related to COVID-19 are individuals who do not recover from their initial infection, making them long haulers. Long-COVID is transitioning from a range of isolated phenomena to higher prevalence rates in patients who contracted COVID-19. Many individuals report issues with cognitive function, referred to as ‘brain fog’, that affect memory, attention, and even language skills. This literature review addresses the available research on Long-COVID and how persistent infection correlates with cognitive difficulties. It aims to explain the neurobiology of Long-COVID and how Long-COVID interacts within …
