Culturally Affirming Independent School Board Governance: Centering The Experiences Of Independent School Board Members Of Color, Christopher S. Dennis Phd

Dissertations

As schools become more diverse, K–12 independent school boards benefit from diversity (Jernigan et al., 2010; Tolbert Smith, 2022). This study examined the narratives of independent school board members of color (BMOC) across the United States’ racialized history of education (Anderson, 1988; Omi & Winant, 2014). The study used a survey (n = 23) and interviews (n = 9) based on Helms’s (1996) racial identity theory and Booth-Bell et al.’s (2021) board governance theory. This multiple case study examined survey responses of BMOC from 17 schools governed by the National Association of Independent Schools (NAIS). Nine respondents were …

Post Racial Reckoning: Montessori Instructors' Perspectives On Teaching Through An Antibias Antiracist Lens, Jasmine E. Williams

Dissertations

Prior to the racial reckoning of 2020, Montessori teacher education programs (MTEPs) have only narrowly focused on social justice education (Aronson et al., 2020; Bartolomè, 2004; Cook, 2015; Cross, 2005; D’Cruz, 2022; King, 1991). Although MTEPs began to respond differently post-reckoning, support for implementing practices like antibias antiracist (ABAR) instruction was often absent. This study sought to understand how the racial reckoning and efforts to include an ABAR lens impacted the teaching practices of instructors in MTEPs. While ABAR-related studies exist in general teacher education (Blanchard et al., 2018; Madkins & Nazar, 2022; Martinez-Alba, Herrera, & Hersi, 2022), few focus …

Leading Through Crisis: San Diego County Schools' Response To The Social Emotional Needs Of All Students, Johana Bielma

Dissertations

When schools reopened, administrators faced the challenge of reintegrating students into in-person learning while addressing the pandemic’s lasting effects on academics, mental health, and school safety. While academic regression was evident, the extent of students’ emotional struggles was less anticipated. Many students exhibited increased irritability and mental health issues such as depression …

Reimagining Pedagogies Of The Prison Yard: Using Ethnotheatre To Embody Transcarceral Conocimiento, Mabelle Reynoso

Dissertations

Latinxs make up 40% of California's population but account for 45% of the prison population and 47% of the jail population (Sawyer, 2023). Their overrepresentation in carceral custody not only impacts the individual but also affects families and communities by limiting access to social, political, and educational capital and agency. In response to gaps in research specific to the collateral impact, this interdisciplinary arts-based qualitative study highlights the experiences of five formerly incarcerated Latino men who participated in an Arts in Corrections playwriting class during their time in a California state prison. This study foregrounds their knowledge as cuentistas (storytellers), …

Latinas In Higher Education: Paving & Weaving Wholeheartedly, Ariela M. Canizal

Dying Young, Brianne L. Overton

Dissertations

Death, often perceived as a disruption to daily life, is an inevitable part of the human experience. While older adults may develop familiarity with mortality through the collective experience of personal and familial losses, young adults generally have limited exposure to death. Despite this, young adults, defined as individuals aged 20 to 34, represent approximately 20% of the U.S. population (U.S. Census Bureau, 2020), and the mortality rate within this age group has been rising over the past decade (Woolf & Schoomaker, 2019). Death among young adults is often overlooked in societal narratives and medical research, which primarily focus on …

Unraveling The Antiviral Mechanisms Of Bat Cells: Processing Of Genomic Rnas By Dicer In Bat Cells Limits Sars-Cov-2 Replication, Iyanuoluwani Owolabi

Dissertations

Bats are reservoirs for numerous viruses that cause serious diseases in other animals and humans. Several mechanisms are proposed to contribute to the tolerance of bats to these pathogens. This study investigates the response of bat cells to double-stranded RNA generated by SARS-CoV-2 replication. Here, we found the involvement of Dicer in the processing of viral genomic RNAs during SARS-CoV-2 infection. Examining RNA sequencing of infected cells, small-interfering RNA (siRNA)-like fragments were found derived from viral RNAs. Depletion of Dicer showed a reduction in these RNAs and an increase in viral loads suggesting unlike other mammals, bats may use Dicer …

The Problem Of The Whiteness Of Wealth, Elizabeth Tharakan

Dissertations

In 2021, households with a White householder made up 65.3% of all U.S. households and held 80.0% of all wealth. Those with a Black householder made up 13.6% of all U.S. households but held only 4.7% of all wealth. And their median wealth ($24,520) was about one-tenth the median wealth of households with a White householder ($250,400). This disparity in Black wealth and White wealth is almost an order of magnitude. I seek to understand why the racial wealth gap exists and what people of any race can learn from a nuanced understanding of the interplay among culture, education, and …

The Paraprofessional-To-Teacher Experience: Moving From The Margins To Front And Center, Joanna Kerster Ross

Paraprofessional hiring pools have tended to be more diverse than teacher hiring pools and changing demographics across the nation could highlight the importance of CRP approaches in education (U.S. Department of Education, 2023; …

Evaluating The Indirect Effect Of Microaffirmations On Intersecting Marginalized Identities And School Sense Of Belonging Among School Psychology Graduate Students, April Pratt

Dissertations

There is a discrepancy between the proportion of school psychologists identified as racially, ethnically, or linguistically diverse (REL) in the United States and the proportion of REL students they serve (Blake et al., 2016; Proctor & Owens, 2019). Current data estimates over 80% of school psychologists identify as white (Goforth et al., 2021), whereas more than 50% of U.S. public school students have non-white racial/ethnic identities (Irwin et al., 2024). In addition to increased recruitment of REL students to school psychology graduate programs, trainers in these programs must implement effective strategies to ensure retention. One method is to increase students’ …

Examining The Effects Of Aryl Hydrocarbon Receptor Activation On Gut Immune Responses, Aspen Elizabeth King

Dissertations

Previous studies conducted in our laboratory suggest that activation of the aryl hydrocarbon receptor (AhR) activation with the prototypical ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) initially suppresses both fecal and serum antigen-specific IgA responses, but fecal antigen-specific IgA levels recover from suppression while serum IgA levels do not. The purpose of the research detailed in this dissertation was to explore two potential mechanisms allowing for the more rapid recovery of antigen-specific IgA in the feces relative to the serum: (1) an increase in myeloid-derived suppressor cells (MDSCs) that enhance IgA antibody responses in intestinal tissues, and (2) an increase in the migration of …

Efficacy Of A Novel Role-Playing Based In-Class Simulation On Enhancing Clinical Judgment Skills In Senior Baccalaureate Nursing Students, Melodie Jolly

The Shifting Landscape Of Harm: Investigating The Phenomenon Of Concept Creep In Harm Perception, Jefferson Sherwood

Dissertations

Concept creep, the gradual semantic expansion of harm-related concepts (Haslam et al., 2020), is a phenomenon garnering increasing attention in the field of psychology and is examined in the context of shifting perceptions of what is considered harmful. While what is considered harmful has shifted throughout generations, why these shifts happen and what motivates society to accept these broadening definitions has yet to be explained. Up to this point individual differences such as activism, risk, empathy, stressful life events, and dark triad personality have yet to be investigated as potential contributors to the expansion of harm-related concepts. Thus, this group …

The Effects Of Retrieval Practice On Knowledge Acquisition And Durable Learning In Undergraduate Nursing Students, Jessica Everritt Gay

Dissertations

Recent reports of unpreparedness and failure to rescue incidents among new graduate nurses are concerning for nurse educators and health care. New graduates must retrieve and apply learned knowledge to make sound clinical decisions, emphasizing the need for durable learning and knowledge acquisition. Durable learning, which involves understanding and recalling learned information days, weeks, or months later is crucial for clinical judgment. Nurse educators should facilitate durable learning through effective, evidence-based learning techniques such as retrieval practice (RP), which has shown promise in health professions education but is underutilized in nursing education.

This study explored the impact of RP on …
