Internalized Heterosexism Through Intersectionality: An Interpretative Phenomenological Analysis, Devon Alexandra Monica Bortfeld

Dissertations

While the impact of LGBQ+ individuals experiencing overt, interpersonal discrimination (i.e., heterosexism) is well-documented, the propensity for stigmatization, invisibilization, and violence to be internalized by LGBQ+ has only recently been examined as a factor contributing to poorer health outcomes. Internalized heterosexism (IH) was defined as the consumption and internalization of negative societal attitudes, assumptions, and beliefs towards homosexuality by LGBQ+ individuals and was linked to multiple forms of psychological distress. However, the methodological and clinical gaps in the research contributed to a clinical utility that was lacking for multiply marginalized LGBQ+ individuals. The purpose of this study aimed to understand …

Healing Circulos(Circles): Putting Our Educator's Mask First, Janet Martinez-Angeles

Dissertations

Educators play a pivotal role in supporting students throughout their educational journeys. In addition to academic instruction, they provide vital guidance for students' social, emotional, and personal development. They work tirelessly to help students navigate the complexities of education and life, often while shouldering multiple responsibilities and roles beyond the classroom. This dynamic contributes to high attrition rates and weakens the educational system. Much like the familiar safety instructions on an airplane, where passengers are reminded to put on their oxygen masks before assisting others, educators must be given the space, resources, and support to tend to their well-being before …

Dissertations

Abstract for:

Screen Foundations: How Pediatric Nurse Practitioners Can Implement ‘Family Media Use Plans’ in Primary Care to Reduce Pediatric Behavior Concerns

Problem: Parents of children 2-5 years-old increasingly reach out to PCPs for escalating behavior concerns, including when the child doesn’t listen well, is inattentive, having tantrums, meltdowns, hitting, yelling, etc. Referrals to psychiatry and/or play therapy result in long waits, or referrals not accepted. Coincidingly, toddler and preschool aged children continue to exceed daily screen time recommendations. This results in a gap of care for families with young children and externalizing behavior.

Methods: This quality improvement project addressed …

Truth, Resilience, And Healing: Deepen Understanding Of Native American Federal Boarding School Histories, Toya D. Holiday

Dissertations

Indigenous communities have endured the long-standing impacts of U.S. Federal Indian boarding school policy. The history of Indigenous boarding school policies and the underlying intent to enact cultural genocide is unknown and unacknowledged. The perspectives of Indigenous Peoples have been excluded from dominant narratives, and until recently, from heritage site programming, leading to intergenerational trauma, fragmented identities, and the misrepresentation of Indigenous cultures and experiences. This basic qualitative study asked the question: When the four-truth framework, developed by the South African Truth and Reconciliation Commission, is applied to U.S. Federal Indian boarding school policy, Native American boarding school history, and …

District Impact On State-Wide Charter School Policy: Has Normandy Schools Collaborative Punctuated The Equilibrium? Charter School Policy Analysis Of The Missouri Department Of Elementary And Secondary Education, Tracey L. Cannon

Dissertations

Abstract

Punctuated Equilibrium Theory, as applied by Niles Eldredge and Stephen Jay Gould (1941-2002) to the study of species evolution, examined the infrequency of morphological change or stasis discontinuity.1 While groundbreaking in the field of Paleontology and the study of fossil change, the theory has been well-fitting to the decision sciences as introduced by Baumgartner and Jones2, in their 1993 and 2010 publications. Recognizing typical, incremental policy change, its use in this research looks at how stasis, stagnant policy can be punctuated by changes in political or societal views. This study examines the impact of heightened problem discussion for agenda …

Enzymatic Characterization Of Bacterial Enzymes And Inhibitors As Potential Antibiotics With New Mechanisms Of Action, Emma Helene Kelley

Dissertations

Bacteria have become increasingly resistant to antibiotics, therefore there is an urgent need for new drug classes of antibiotics to help fight antibiotic infections. To this end, our research is focused on inhibitors of dizinc metalloenzymes N-succinyl-L,L-diaminopimelic acid desuccinylase (DapE), an enzyme in the lysine biosynthesis pathway, N-acetyl-L-ornithine deacetylase enzyme (ArgE), an enzyme in the arginine biosynthesis pathway, and sodium-dependent NADH: ubiquinone oxidoreductase (Na+-NQR) enzyme, a respiratory complex enzyme as promising drug targets. DapE, ArgE, and Na+-NQR and are only present in bacteria, including ESKAPE pathogens that can cause potentially deadly infections, thus inhibitors of DapE, ArgE, and Na+-NQR offer …

The De Mau Mau Conspiracy: The Specter Of Black Vietnam Veterans In The Exercise Of Police Power, 1968-1976, Ina Cox

Dissertations

A forgotten and bizarre event encapsulates the violent decay that characterized the pivotal years the United States endured in the wake of the Vietnam War. Black veterans—guerrilla combat-trained, politically awakened by war, and disillusioned with the entrenched racial order at home—emerged as totems in a fearful, cynical political culture wracked by violence. Men overrepresented in the projection of American power abroad now stood as symbols of its fragility within, potential vessels of retribution for centuries of domestic and global oppression. This anxiety, merging with widespread protests and political upheaval, intensified the belief that American cities stood on the brink of …

Ethnicity Through Education: An Analysis Of The Influence Of Formal Education On Ethnicity In Garo Hills, Samirkumar Benedict Talati

Dissertations

In recent decades, the positioning of ethnic groups within the educational context has emerged as an important area of scholarly investigation. The structural, institutional, and local contexts often determine how ethnic groups shape their ethnicity. This study draws from panethnicity and social ontology frameworks to examine ethnic consciousness and the processes of solidarity-building across subgroups within the Garo community in the Garo Hills of Meghalaya. The unequal distribution of educational resources has led to socioeconomic disparities and class formation within Garo society, creating a growing divide between the educated and uneducated Garos. While acknowledging the diversity among subgroups, this study …

St. Louis, Missouri’S Gayborhood And Washington, Dc’S Black Lives Matter Plaza: Revealing The Healing Potential Of Resistance Stories That Are Grounded In Place, Ryan R. Lindsay, Lotte I. Lent, Ackesha J. Patrick

Dissertations

Oppressed people resist, even when facing severe consequences for doing so. At the core of systemic oppression—genocide, slavery, racism, and sexism—is a drive to control and dehumanize. Resistance, however, can serve as a powerful act of rehumanization. From enslaved individuals fleeing plantations to LGBTQ+ individuals risking arrest to gather in mid-20th-century bars, resistance reclaims power and autonomy under oppressive regimes. This study applies South Africa’s Truth and Reconciliation Commission (TRC) “four truths” framework—comprising forensic, personal, social, and healing truths—to the interpretation of contested heritage sites. We argue that sites commemorating resistance hold transformative potential for individual and community healing. Using …

Investigating The Consequences Of Conjugated And Secreted Isg15 On Coronavirus Pathogenesis, Mudassir Syed Ali

Dissertations

Coronaviruses have evolved a breadth of mechanisms to antagonize host innate immune responses. One widely studied mechanism is the ability to deconjugate ISG15 from target proteins in a process called deISGylation, which is catalyzed by the papain-like protease (PLP) domain of viral non-structural protein (nsp) 3. Since PLP activity is required for viral replication, it has been challenging to generate an infectious virus with a PLP that maintains protease activity but has lost deISGylase activity. In this study, we generated a chimeric MHV-A59 with its PLP2 domain replaced with that of the human coronavirus HKU1, which has been documented to …

Interrogating The Dispersal Process And Relevant Genes In Vibrio Fischeri, Jeremy Esin

Dissertations

Biofilms are aggregates of bacteria encased in a matrix that shields bacteria from environmental hazards. These structures are formed in response to cues from the environment and drive colonization of new niches. Biofilms can be both beneficial and detrimental. Largely, research focuses on biofilms that have negative outcomes in clinical, environmental, and economical settings. However, the value of beneficial biofilms is recognized and studied. The marine bacterium Vibrio fischeri is part of a model system for studying symbiotic biofilms in a eukaryotic host. V. fischeri produces a transient biofilm at the surface of a specialized light organ and then disperses …

Culturally Responsive Intimate Partner Violence (Ipv) Service Needs Among African Immigrant Women: Examining The Impact Of Cultural Norms And Psychosocial Barriers On Safety Perceptions And Help-Seeking Behaviors, Titilayo Ogunbambi

Dissertations

Intimate Partner Violence (IPV) remains a pervasive public health and social justice issue globally, with African immigrant women in the United States facing compounded challenges as they navigate cultural, structural, and systemic barriers, including migration-related vulnerabilities and attachment to cultural values that shape their decisions and experiences. Although formal IPV services exist, they often fail to address the lived realities and culturally specific needs of this population, leading to underutilization and barriers in seeking help. This qualitative study examines how cultural norms, psychosocial barriers, and systemic inequities influence safety perceptions and help-seeking behaviors among African immigrant women survivors of IPV. …

The Rose That Grew From Concrete: Exploring The Romantic Experiences Of Black Men With Histories Of Childhood Sexual Abuse, Tatyana Nichelle Smith

Dissertations

Contemporary research typically characterizes Black heterosexual relationships by dismal marriage and divorce rates, largely ignoring the reality of how Black men develop attachments with their romantic partners and therefore continuing to perpetuate deficit perspectives of Black men (e.g., the cause of conflictual romantic relationships and “broken” Black families). What may be less understood about these relationships is the influence of childhood trauma, such as childhood sexual abuse, and Black men’s experiences of gender role conflict. Research shows that Black men’s experiences of childhood sexual abuse and socialization about masculinity have important implications for how they come to view themselves and …

Diagnosis By Algorithm: The Transformative Impact Of Social Media–Driven Adhd Self-Diagnosis For Women Over 30 And The Proposal Of Neurotype Strain Theory, Rebecca Lynn Sevin

Dissertations

This dissertation explores the phenomenon of adult women who self-diagnosed Attention Deficit Hyperactivity Disorder (ADHD) through content encountered on social media platforms. Drawing on interpretive phenomenological analysis of ten in-depth interviews, the study investigates the emotional, cognitive, and institutional dimensions of this self-diagnosis process. Participants, all over the age of 30, reported that social media played a transformative role in helping them recognize ADHD traits in themselves. Rather than being misinformed or seeking shortcuts, participants engaged thoughtfully with ADHD-related content, valuing lived experience itself as a meaningful source of recognition and reflection. Their engagement was not primarily with educational materials …

The Correlation Between Depression And Gendered Racism Among Black Women, Charmagne M. King

Dissertations

Black women face unique challenges related to intersecting racial and gender-based discrimination, often referred to as gendered racism. Previous research has indicated this form of oppression may significantly affect mental health, particularly depression. However, few studies have examined how gendered racism interacts with racial identity and demographic factors (e.g., age, marital status, geographical location) to predict depressive symptoms. Using a sample of 164 self-identified Black women, this study investigated the correlational relationship between gendered racism and depression among Black women and examined how gendered racism, racial identity, and key covariates (age, marital status, and geographical location) predict depressive symptomatology. The …
