Beyond Symptoms: Examining Perinatal Mental Health Care Among Black, Indigenous And People Of Color With Polyendocrine Metabolic Ovarian Syndrome, Vinaya Thomas

Electronic Theses and Dissertations

Perinatal mood and anxiety disorders (PMADs) are as a public health concern in the United States. Individuals from minoritized racial/ethnic groups face a significantly elevated risk of maternal morbidity, mortality, mental health disorders, and associated adverse outcomes. Emerging studies also reveal a higher likelihood of experiencing perinatal mental health concerns in individuals with polycystic ovarian syndrome (PCOS), currently known as polyendocrine metabolic ovarian syndrome (PMOS). People who identify as Black, Indigenous, or a person of color (BIPOC) face unique healthcare challenges given the added structural and social burdens. This online survey study aimed to 1) understand the relationship between PMOS …

Kindergarten Teachers’ Perceptions Of Instructional Approaches For Teaching Sequencing Concepts: Worksheet, Hands-On, And Beebot-Integrated Lessons, Savannah P. Partin

Electronic Theses and Dissertations

The purpose of this qualitative multiple-case study was to explore kindergarten teachers’ perceptions of three instructional approaches for teaching sequencing concepts: worksheet-based instruction, hands-on manipulative instruction, and BeeBot-integrated instruction. Sequencing is a foundational early literacy skill that supports reading comprehension, story retelling, and understanding the order of events. Although sequencing is commonly taught through traditional instructional methods, limited research has examined how kindergarten teachers perceive the use of educational robotics as a tool for literacy instruction. The study was guided by constructivist theory, sociocultural theory, and developmental systems theory. Participants included six kindergarten teachers from a public elementary school in …

Computational Studies Of Triplet State Formation In Zinc Dipyrrin Complexes, Reuben Kwabla Adigbli

Electronic Theses and Dissertations

Zinc dipyrromethene complexes are promising earth-abundant photosensitizers due to their strong visible-light absorption and tunable excited states. To rationally design them for photocatalysis and photodynamic therapy, a molecular-level understanding of triplet-state formation is needed, but details of intersystem crossing remain unclear. To study the effect of π-extension, we synthesized an indole-substituted zinc dipyrrin complex: the dipyrromethane ligand was prepared from indole and mesitaldehyde, oxidized to the dipyrromethene, then coordinated with zinc. DFT and TD-DFT calculations determined ground and excited-state geometries and energies in different solvents, modeled absorption spectra, and visualized charge distributions. The results show how solvent polarity shifts energies …

An Assessment Of Accessibility And Affordability Of Inpatient Psychiatric Care In Tennessee, Kailee Havrda

Electronic Theses and Dissertations

Introduction: Access to mental health has seen changes over the past decade, but little research and attention have been given to access to inpatient psychiatric facilities. Inpatient psychiatric care is crucial for patients experiencing mental health emergencies who need immediate access to care. Gaps in spatial accessibility, affordability, and the access and assessment process were identified due to a lack of available information in the field.

Methods: Secondary data from the Tennessee Department of Health were used to assess financial accessibility through payer source charges and patient encounters, as well as through mapping of inpatient psychiatric facilities and conducting drive …

Exploring Competitive Dynamics Between Pseudomonas Baetica And Salmonella In A Polymicrobial System, Braxton E.M. Stout

Electronic Theses and Dissertations

The global rise in antimicrobial resistance has catalyzed a greater focus on polymicrobial research aimed at characterizing microbial interactions and uncovering new therapeutic strategies. Though it has long been of interest, environmental soil-derived bacteria remain largely under-represented in research and thus uncharacterized in this field. This project aimed to identify soil microbes that display inhibitory mechanisms to potential nosocomial pathogens. Soil sample S1S3-2 displayed inhibitory phenotypes toward numerous bacteria and was identified as Pseudomonas baetica. In both planktonic and biofilm growth, P. baetica was able to inhibit Salmonella arizonae through a contact-dependent and temperature-dependent manner. Screening of a transposon insertion …

The study examined the strategies that facilitated women’s progression into leadership and the systemic barriers that may limit their advancement within the trucking industry. Semistructured interviews were conducted with 11 female trucking professionals, and the resulting data were analyzed using thematic analysis. Six themes emerged from the findings: (a) independence, …

Don’T Let Us Down: A Phenomenological Study Of African American Employees’ Perceptions Regarding The Benefits Of Professional Development In Student Affairs, Courtney Nicole Demings

Electronic Theses and Dissertations

The experiences of student affairs professionals are critical to the success of higher education, allowing for a concentrated exploration of African American student affairs professionals who are often employed in 2-year U.S. community colleges. The general problem was that African Americans may leave student affairs in community colleges if they do not perceive supervisory support for professional development and, in turn, career advancement. The purpose of this dissertation was to understand and interpret their lived experiences, illuminate the barriers to their career advancement, and discuss the impact of supervisory support. As such, this action research employed qualitative research through the …

Designing Inclusive Stem Curricula: A Design-Based Study Of Teacher Learning And A Queer Inclusive Framework, Kyle Nolting

Electronic Theses and Dissertations

STEM (Science, Technology, Engineering, and Mathematics) education has historically marginalized queer identities, shaping inaccurate curricula and fostering unwelcoming classroom environments. To address this, my research uses design-based research to investigate the design of queer-inclusive STEM curricular resources. I partnered with in-service secondary STEM teachers amidst a series of professional development courses to co-create curricular resources. My research is grounded in queer theory, using a Gender Inclusive Framework to collaboratively develop inclusive design principles. My findings revealed a strong desire by teachers for more authentic and fluid representations of gender and sexuality in STEM curricula, particularly beyond the biological science discipline. …

Asian American Men's Experiences Of Gendered Racism In Online Competitive Gaming, Calvin Weiting Lee

Electronic Theses and Dissertations

In the U.S., Asian Americans men make up a large portion of active players in online competitive video games. In these settings, harassment, racism, and hate speech are prevalent and often normalized. The purpose of this study was to explore Asian American men’s experiences of gendered racism in online competitive gaming spaces. Using an Interpretative Phenomenological Analysis approach (Smith, Flowers, & Larkin, 2022) and applying the Intersectionality Framework (Crenshaw, 1989; Collins, 2000), six Asian American men were interviewed about their experiences of gendered racism while playing online competitive games. Two Group Experiential Themes emerged from their accounts: 1) Gendered racism …

Biases Toward Threat In Categorization And Attention Allocation When Evaluating Static And Dynamic Emotional Crowds, Delaney Mcdonagh

Electronic Theses and Dissertations

Visual representations are often biased, and these biases can manifest across many different stages of perception. For example, when categorizing nuanced, ambiguous, or fleeting emotional expressions, most perceivers are biased to interpret expressions as negative. Biases also manifest at the level of attention-allocation as observers dynamically examine and attend to expressions as they visually navigate a crowd. To comprehensively understand biased emotion perception, it remains critical to understand how bias manifests across the process of making emotional judgements, both as observers gather information about faces over time and as they make a final categorization of what they see. Biased patterns …

Behind Prison Walls: Unmasking The Victimization Experience Of A Transgender Inmate: A Narrative Study, Kevin E. Hemminger

Electronic Theses and Dissertations

Transgender individuals experience disproportionately high rates of victimization within the U.S. criminal justice system, at rates some studies estimate as four times greater than those of cisgender individuals (Marchi et al., 2025). Victimization may occur at the hands of correctional officers, institutional staff, or fellow inmates. This narrative study focuses on the life story of a formerly incarcerated transgender woman, tracing her experiences before incarceration, throughout her time at two different correctional facilities in two different states, and her life following release. While Community Based Research (CBR) was not adopted as a formal methodological framework, its principles — centering lived …

Cultural Humility, A Salve For Romantic Relationship Conflict, Lena Blum

Electronic Theses and Dissertations

Conflict communication and having a relationship consisting of differing sociocultural backgrounds (DISC Couples) have been viewed as obstacles or at best hindrances of relationship satisfaction in earlier couples’ psychology literature. More recent literature makes an argument that it is not merely conflict communication or the differences of culture within a couple, but rather how couples navigate both conflict and differences that impact relationship satisfaction. The present work aims to investigate the role of cultural humility in the association between cultural conflict communication and relationship satisfaction, as well as its relationship with the frequency of cultural conflict communication among DISC couples. …

Investigating Caveolar Systems: Spatiotemporal Quantification Of Caveolin-1 And The Mechanotransducive Function Of Ehd2, Jasper Stanae Farrington

Electronic Theses and Dissertations

Caveolae are 50-100nm cholesterol rich flask shaped invaginations found in many differentiated cells. Namely, these structures have been seen to be abundant in endothelial cells where they are involved in many signaling contexts. However, under mechanical stress, the characteristics of caveolae alter, flattening to increase membrane compliance, while displaced proteins can shift from structural roles to mechanosensitive signaling functions. Caveolin-1 (Cav1) is the principal protein required for Caveolar formation while Eps15 Homology Domain Containing Protein 2 (EHD2) is a membrane ATPase that acts to stabilize caveolae at the surface. Despite their emerging importance, understanding the organization and dynamic regulation of …

Electronic Theses and Dissertations

This thesis examines the June 2023 closure of the North American Indian Cultures Hall (NAICH) at the Denver Museum of Nature and Science (DMNS) as a critical moment of institutional transformation. Through a case study approach grounded in archival research, interviews, surveys, and discourse analysis of social media posts and public commentary, this project investigates how exhibit closures reflect shifting dynamics of curatorial authority, Indigenous representation, and settler colonial structures. Guided by theoretical frameworks of settler colonial theory, desire-based research, institutional critique, and museum anthropology, this study explores how internal museum politics, community opinion, and public narratives reshape accountability and …

Examining Intimate Partner Violence After Pediatric Traumatic Brain Injury, Rebecca R. Suzuki

Electronic Theses and Dissertations

Pediatric traumatic brain injury (TBI) is linked with social problems in peer relationships that can last into adulthood. Little is known about how social problems impact the development of intimate relationships as pediatric TBI survivors grow up. This study addressed this gap by examining risk of intimate partner violence (IPV) in a sample of 50 young adult survivors of pediatric TBI prior to age 13 (M age = 22.96, SD = 1.70, 60% women) and tested social information processing (SIP) as a potential process through which TBI influences risk for IPV. Participants were recruited via Prolific and social media …

Exploring Foundations Of Animal Host-Microbe Interactions In A Freshwater Sponge, Jacob S. Pawley

Electronic Theses and Dissertations

The most ancient eukaryotic immune defense mechanisms evolved in unicellular species. Multicellular eukaryotes, however, expanded these mechanisms to meet challenges unique to multicellular life, including barrier formation, long-distance cell signaling, and coordinated responses that eliminate microbial threats while minimizing damage to the host. As such, animal immune signaling pathways are exceptionally intricate and diverse. Though, most of what is understood about animal host–microbe interactions stems from a small handful of model systems. Here, I evaluate host–microbe interactions and innate immunity in sponges using the highly tractable freshwater sponge, Ephydatia muelleri. I report the discovery of an external host-derived matrix …

Protest, Police, Peace, And Violence: Understanding Variation In Police Violence At Protests, Louis Pascarella

Electronic Theses and Dissertations

Why do police engage in violence at some protests but not others? Existing research highlights the importance of protest characteristics, political context, police culture, organizational incentives, and interactions between protesters and law enforcement. While these factors help explain patterns of repression, they provide limited insight into why police responses can shift rapidly from restraint to widespread violence during the course of a protest event.

This dissertation examines variation in police violence during the 2020 George Floyd Uprising through a comparative analysis of protest events in Denver, Colorado and Seattle, Washington. Drawing on original event reconstructions based on livestreams, helicopter footage, …

Well-Being Beyond The Binary In Perinatal Healthcare: An Application Of Reproductive Justice, Orphea D. Wright

Electronic Theses and Dissertations

Gender diverse birthing individuals face several systemic barriers to accessing affirming and empowering perinatal healthcare. The present study utilizes the term gender diverse and the abbreviation TGE to describe those who self-identify as broadly non-cisgender, an umbrella term for people whose gender identity differs from their sex assigned at birth. Gender identities that may be included in this definition include transgender/trans, gender expansive, non-binary, gender fluid, gender nonconforming, gender variant, gender queer/queer, and/or agender. Gender diverse individuals face unique barriers in perinatal healthcare due to the pervasiveness of cisnormativity in perinatal healthcare spaces. Research has documented the harm caused to …

Mystical Revelation And Knowledge Of God: Reclaiming Spirituality In Theology Through The Mystics, Elizabeth A. Merski

Electronic Theses and Dissertations

Since the scholastic era, the pursuit of God has occurred preeminently through reason, leading to an imbalanced theology of God that persists to the present day in the form of intellect-centered theology. As a resolution, this work proposes that the mobilization of private, mystical revelation as a source of legitimized theological knowledge of God has the potential to close the existent epistemological gap between reason/belief and theology/spirituality, demonstrating the integral unity between authentic knowledge of God and the receiver’s personal acceptance of God in faith. After examining the required methodological components for the discipline of theology and identifying criteria for …

The Person As Foundation Of Responsibility: The Insufficiency Of Rights-Based Human Development Approaches, Jaclyn Berg

Electronic Theses and Dissertations

Building on the plethora of research that demonstrates the way rights language has been more useful for those with wealth and power to further expand capitalist markets, this text extends that criticism to human development programs and institutions. While they claim to be directed towards addressing global issues of poverty and hunger as well as climate crises, they continue to treat the symptoms without accurately diagnosing the disease. Approaches to development that rely on rights without questioning the way rights have been influenced by neoliberal capitalists or without questioning the capitalist global economic system will never be able to achieve …

The Decline Of Confidence In The U.S. Supreme Court: Evidence From The General Social Survey, 2004-2024, Lola Dragosavac

Electronic Theses and Dissertations

This study examines public confidence in the United States Supreme Court and whether confidence has declined between 2004 and 2024. It also investigates whether demographic characteristics, political ideology, and confidence in other political institutions help explain the variation in confidence levels. Using data from the General Social Survey (GSS) for 2004, 2014, and 2024, this study employs a binary logistic regression approach to examine the predictors of confidence in the Court. The findings indicate that confidence in the Supreme Court declined significantly over the twenty-year period. Political ideology emerged as a strong predictor of confidence, with conservatives over three times …

Impact Of Taped Problems Intervention Modification On Children With Deafness, Clyniece Hodge

Electronic Theses and Dissertations

Children with hearing loss are at an increased risk of experiencing setbacks in various areas of life, including academic performance and employment opportunities. Academically, they are likely to experience poor academic achievement in reading, as well as in mathematics (ASHA, 2013). In comparison to gifted hearing students and average-ability hearing students, students with hearing loss are at a higher risk of low mathematics performance (Hassan & Mohammed, 2019). Despite these known challenges and risk factors, limited research has been conducted to identify effective intervention strategies for improving mathematical outcomes among this population. As such, this study aimed to evaluate the …

Dialogic Communication Ethics As A Hopeful Response To Artificial Intelligence, Kristen Haldeman

Electronic Theses and Dissertations

Within the past five years, a new technology has dominated modern culture: artificial intelligence. With a multiplicity of ways to respond to this new environment, this dissertation situates a response to artificial intelligence by combining the media ecology and communication ethics perspectives. Media ecology explores historical roots and biases of technology to learn about their influence of humanity. A dialogic communication ethics seeks to find an opening for hope to emerge. Hope, grounded in the works of Jacques Ellul and the Christian tradition, offers a new rhetorical perspective by shifting focus away from technology and to our neighbor.

Between Care And Despair: An Existential Phenomenological Study Of Eco-Anxiety As Lived Experience, Conor H. Sukhdeo

Electronic Theses and Dissertations

This dissertation explores the lived experience of eco-anxiety among young adults aware of the ongoing ecological crisis but not directly exposed to climate-related disasters. Grounded in the human science tradition, ecopsychology, and existential phenomenology, this study employed Scott Churchill’s (2022) approach to Existential Phenomenological Research (EPR) to deepen our understanding of the phenomenon of eco-anxiety. Four participants, residing in Pittsburgh and aged 18-25, produced written experiential descriptions and participated in open-ended phenomenological interviews. As outlined by EPR, this data was analyzed through meaning unit delineation, imaginative variation, phenomenological reduction, and structural synthesis to produce individual situated structures of eco-anxiety for …

The Narrative In The Algorithm: Storytelling, World Literature, And The Smartphone, Chad Szalkowski-Ference

Electronic Theses and Dissertations

In this dissertation, I interrogate the role algorithms, artificial intelligence, and smartphone technology play in contemporary world literature. My analysis begins with the post-truth condition, which speaks to the contemporary era’s embrace of alternative facts, authoritarianism, and conspiratorial thinking. I draw on narrative theory and paradigms of world literature to show how “algorithmic reasoning” has led to a state of paranoid persecution. This reasoning has forged new collectivities across traditional borders. Additionally, I show that these new collectivities and new technologies have produced new narrative points of view: the algorithmic first- and third-person, allowing narratives to retain the intimacy and …

The Internet Did This To Me: Forms, Consequences, And Coping Strategies Of Cyberbullying, Isaac Oppong

Electronic Theses and Dissertations

This study examined self-reported cyberbullying experiences recounted in a subreddit (r/cyberbullying) to identify forms of cyberbullying, its effects, and ways to cope with it. The findings indicate that there are several types of cyberbullying, such as verbal aggression, deceptive manipulation, privacy invasion, and coercive control. These experiences led to emotional, social, and behavioral consequences, including fear, anxiety, withdrawal, and decreased online activity. Based on concepts from Social Information Processing theory and Symbolic Interactionism, this study reveals how cyberbullying can produce the same or similar consequences as traditional bullying. People experienced disturbances in their self-presentation, contended with spoiled identities, and dealt …

Understanding College Student Expectancies Of Simultaneous Engagement In Multiple Risk Behaviors: A Measurement Development And Model Testing Study, Shelby Whalen

Electronic Theses and Dissertations

Risky behaviors, actions that may cause physical, psychological, social, or economic harm to oneself or others, are prevalent among college students. While significant research has focused on single high-risk behaviors of alcohol use, drug use, gambling, and gaming separately, students frequently engage in multiple high-risk behaviors simultaneously, such as drinking alcohol while gambling. Research shows that students have distinct and specific expectancies about what happens when they engage in a risk behavior, however, minimal research has examined students’ perceptions or reasons for simultaneous poly-risk behavior engagement. This multi-phase project characterized students’ outcome expectancies for simultaneous poly-risk behavior combinations, developed and …

Race, Sex, And Age Disparities In Homicide Clearance Rates In Tennessee: An Intersectional Approach, Teliyah Cobb

Electronic Theses and Dissertations

Demographic factors can influence homicide solvability. This study examines the relationship between victim characteristics and homicide clearance rates in Tennessee from 2001 to 2023. Using an intersectional approach, it assesses whether victim characteristics both individually and in combination are related to case solvability. Variables of interest include: (1) victim race, age range, and sex; (2) year the case was reported; (3) crime type; (4) whether the case was cleared; and (5) the circumstances leading to clearance. A total of 11,534 homicide cases from the Tennessee Incident-Based Reporting System were analyzed.

Findings indicate that individual victim characteristics do not significantly predict …
