Towards Explainable Ai On Graph Neural Networks: Xaig, Jiaxing Zhang

Dissertations

In the evolving landscape of artificial intelligence (AI), Graph Neural Networks (GNNs) have garnered growing prominence for their adeptness in processing graph-structured data. Despite this, the interpretability of their predictions often remains elusive. The demand for transparency and explainability in complex prediction models has reached unprecedented levels. To address this, post-hoc instance-level explanation techniques have emerged, aiming to unveil the rationale behind GNN predictions. These techniques endeavor to unearth substructures that elucidate the predictive behavior of trained GNNs.

This dissertation embarks on an exploration of Explainable AI (XAI) technologies within the realm of GNNs. Amid the challenges posed by the …

Constructing Portraits Of Elementary Teachers Of Ethnic Studies: Examining The Narratives Of Anti-Racist Educators In An Era Of Common Core Curriculum And Instruction, Jennifer S. Manglicmot

Dissertations

The emergence of policies requiring ethnic studies courses in California’s secondary and higher education institutions amplified calls for anti-racist pedagogy and content in all K-12 grade levels. Currently, little empirical research exists on how ethnic studies is taught in elementary school classrooms. This absence is significant because instruction in these settings tend to focus heavily on meeting state content standards (i.e. Common Core), frameworks which have been critiqued as ignoring communities of Color epistemologies and promoting color-evasive ideologies, among other concerns. Through interviews, classroom observations, and document analysis, this qualitative multiple-case study explored how anti-racist and ethnic studies pedagogies are …

Black Parents’ Use Of Educational Advocates: Disrupting Structural And Systemic Racism In Education, Fredericka R. Butler Phd

Dissertations

Research indicates that educators’ deficit perceptions of Black students and their families factor into Black student overrepresentation in disciplinary and special education referrals and underrepresentation in advanced coursework (Annamma et al., 2014; Ford et al., 2023). This prevalence of implicit bias is documented, as is the significance of Black parent involvement in their children’s education (Latunde & Clark-Louque, 2016). Black parents’ awareness of educator racism encourages distrust of educators and interferes with cultivating effective home-school relationships that encourage successful student outcomes. School districts offer the services of educational advocates to provide support to parents whose children are referred for special …

Through The Four Truth Lens: Exploring Climate Change Communication At Joshua Tree And Glacier Bay National Parks, Heather A. Waterman, Amanda Berlinski

Dissertations

The climate crisis threatens our global communities, cultures, and futures. Communication that brings climate change into everyday conversations and galvanizes the public to respond to it collectively is needed. However, political divides in the United States make climate change a contested heritage topic that is challenging to address. The purpose of this applied, basic qualitative research study was to use the Four Truth Framework, developed by the South African Truth and Reconciliation Commission, to investigate climate change communication at Joshua Tree National Park in California and Glacier Bay National Park in Alaska. Climate change affects national parks more than other …

Reclaiming Data: A Participatory Action Research Study To Empower Educators, Diana Hammond

Dissertations

Abstract

Currently, the day-to-day data collection and analysis work of teachers is often only deemed valuable if it is easily observed and quantitatively recorded. Teachers are asked to produce results with an incomplete set of tools and are then personally blamed — instead of blame being placed on the structural system — when the desired results don’t manifest. This participatory action research (PAR) study challenged the status quo by asking: What if teachers were empowered to expand their definition of data to include the rich, qualitative data at their fingertips, and what if teachers’ experience and intuition were valued instead …

Building A Grounded Theory Of Resilience Among Survivors Of Chronic Ischemic Stroke, Erin Marie Tompkins Doan

Dissertations

Abstract

Stroke is disruptive with elusive recovery and adjustment. Beyond traditional aspects of stroke rehabilitation, literature suggests adjustment to stroke should also include intervention with focus on resilience. A gap exists between conceptualization, theoretical models, and strategies for supporting resilience in persons with chronic ischemic stroke. This three-manuscript dissertation research comprised a scoping literature review, a pilot study, and a phenomenological case study. We employed a convergent mixed methods design in which we implemented and studied outcomes of an adaptive mindfulness intervention. We implemented eight focus groups with eight adults and four individual interviews over 13 months. The Brief Resilience …

Leading Change For Transgender And Gender Diverse Healthcare: Assessing Organizational Readiness, Braxten Lovett

Dissertations

Background: Transgender and gender-diverse (TGD) individuals face persistent stigma and systemic discrimination across multiple societal domains, with healthcare settings—intended as safe spaces—often being among the most harmful. Despite increased visibility of TGD populations and growing research on their health inequities, inclusive healthcare remains insufficiently addressed by many healthcare leaders, adding to the urgency to advance equitable, inclusive care. Additionally, structural cisnormativity and binary gender frameworks continue to perpetuate misinformation, erasure, and health disparities. Addressing these entrenched barriers requires systemic reform rooted in cultural humility, inclusive practices, and a commitment to dismantling cisnormative bias within healthcare delivery and policy. This study …

Parent’S Health Literacy And Stress Level In The Inpatient Pediatric Setting, Tina C. Smith

Dissertations

Purpose: This study examined the relationship between parent health literacy and stress levels during their child’s inpatient hospitalization.

Background: In 2019, over five million pediatric hospitalizations occurred in the United States. Parents are central to their child’s care, but stress and sociodemographic factors may hinder their ability to understand and apply health information. This study explored how stress and other variables impact parent health literacy during hospitalization.

Methods: A cross-sectional design included a demographic survey, the Perceived Stress Scale (PSS-10), and the Newest Vital Sign (NVS). Bivariate analyses (Chi-square, t-tests) and logistic regression were used to assess …

Does The Value Last? Exploring The Longitudinal Value Of A Research Experience For Preservice Science Teachers, Elizabeth A. Leong

Dissertations

Little attention has been given to the preparation of secondary preservice science teachers (PST) to meet the vision for science teaching and learning outlined in A Framework for K-12 Science Education. Existing literature suggests PSTs would benefit from authentic engagement in scientific research. But research experiences for preservice science teachers or preRETs are rare (Krim et al., 2019). This longitudinal qualitative case study explores the value retained one year after participation in a preRET, which engages PSTs in scientific research and education-focused professional learning. This study utilizes the preRET Value Creation Model (preRET VCM) (Authors, 2024), which overlays the Value-Creation …

Jewish College Students' Experiences Of Belonging, Identity, And Inclusion Within Campus Dei Initiatives, Laurence Allen Bolotin

Dissertations

Jewish college students navigate complex identities within higher education, often facing challenges related to antisemitism, exclusion, and the omission of religious identity within many Diversity, Equity, and Inclusion (DEI) initiatives. This qualitative narrative inquiry explores the lived experiences of Jewish undergraduate students at public universities across the United States, examining their perceptions of belonging and the effectiveness of campus DEI initiatives in addressing their needs. Grounded in Jewish Critical Theory (JewishCrit), this study analyzes semi-structured interviews with 11 Jewish students, identifying five key themes: Belonging and Community, Intersectionality and Identity, Experiences with Antisemitism, Institutional Responses and DEI Initiatives, and the …

The Meaning Of Mission At A Catholic, Liberal Arts College, Ashley Nora Gisiger

Dissertations

This qualitative case study research aimed to uncover how students engage with institutional mission to understand: how the mission of a Catholic, liberal arts college contributes to the development of its undergraduate students and how higher education professionals integrate mission throughout the community. Semi-structured interviews allowed students, faculty, staff, and administrative perspectives to highlight how this work happens at a Benedictine college. Participants highlighted how their experience of mission contributed to their intellectual curiosity, their sense of self through community, and their ability to connect their education to the world at large and beyond their present academic experience. The higher …

Creating A Positive Social-Emotional Learning Environment For Transgender Students: A Post-Pandemic Participatory Action Research, Mark Christopher Maranto

Dissertations

This qualitative research employing participatory action protocols (PAR) engages a limited number of gender minority adolescents (current transgender, nonbinary, and gender-fluid secondary students) and allied staff members at one large Midwestern public high school district. The principal purpose is to improve transgender secondary student schooling experiences. This study extends the current educational discourse on SEL (social-emotional learning) in post-pandemic high schools as far as the commitment to improving students' sense of belonging, growth mindset, resilience, and well-being should be a top priority for all educators. The primary researcher positions all participants as co-researchers to explore ways that could improve the …

Mirrors And Windows: Exploring Queer Identity Representation In Graduate Curriculum, Brody C. Tate

Dissertations

Queer representation in higher education curricula remains sparse, particularly at the graduate level, leaving many students without mirrors to reflect their identities or windows into broader queer experiences. This dissertation explores the extent to which queer graduate students perceive their identities as represented in their academic coursework. Using a narrative ethnographic approach, this study amplifies the voices of queer students, examining their lived experiences in relation to curriculum design, classroom discussions, and institutional inclusion. Framed through Queer Theory and Emily Style’s (1988) “Curriculum as Windows and Mirrors,” this research interrogates heteronormativity in graduate education and highlights the importance of visibility, …

Liberatory Love: Exploring Educators’ Perspectives In Alternative Education, Kamala J. Mallipudi

Dissertations

Establishing an operational understanding of love is difficult. The struggle is magnified when attempting to create a shared vision of love across a group of educators. As Freire (1970/2005) and Darder (2011) affirmed, academic success is advanced when educators demonstrate love as part of their praxis. Continuation high schools represent a population of at-promise students who stand to gain much when their educators employ liberatory love practices. This study examined how educators’ perceptions about liberatory love are shifted or formed when they read, discuss, and reflect on the topic with their colleagues. This study drew on critical pedagogy and engaged …

Belonging Is Resistance: Illuminating The Power Of Women Of Color Mid-Level Administrators In Higher Education, Rachelle Ann Martinez

Dissertations

Resistance has long been a mechanism through which the dominant norms of society are challenged in the name of social justice. White supremacy, heteropatriarchy, and neoliberalism make it difficult for institutions of higher education to increase diversity, advance equity, and prioritize inclusion. Although these systems of domination adversely impact the belonging of all campus stakeholders, the experiences of mid-level administrators are relatively overlooked, and feeling undervalued and underappreciated is a top reason for many, especially women and people of color, who leave the profession altogether. This qualitative study utilized narrative inquiry to understand how dominant societal norms adversely impact the …

Advancing Equity In Financial Aid For Black Students: A Document Analysis Study Of Student Equity Plans In California Community Colleges, Edwina Williams

Dissertations

This study examined how California Community Colleges (CCCs) constructed financial aid discourse in Student Equity Plans (SEPs) and assessed whether these strategies mitigated or perpetuated racial disparities for Black students. Previous scholarship identified racial inequities in financial aid systems and explored how equity planning documents addressed race; yet, the influence of institutional discourse on financial aid access remained underexamined. This study contributed to the literature by applying critical race hermeneutics (CRH) to examine how SEPs outlined financial aid strategies, with particular attention to the framing of work–study opportunities and the extent to which the SEP intended to employ race-conscious approaches. …

Hire Outcomes: The African American Educator Experience Of Equity And Diversity In Education, Myeshia Whigham

Dissertations

African American educators have remained significantly underrepresented in U.S. public schools, a reality shaped by systemic racism, exclusionary hiring practices, and the dominance of white cultural norms in education (Anderson, 1988; Farinde-Wu et al., 2020; Fenwick, 2022). These barriers include microaggressions, anti-Blackness, and limited institutional support (Campbell, 2022; Crenshaw, 1994; Ingersoll et al., 2019; Ladson-Billings, 2021a). Despite these challenges, African American educators bring and practice culturally relevant pedagogy, an approach that affirms students’ cultural identities and creates a stronger sense of belonging for educators and students of color (Ladson-Billings, 2021a; Love, 2019a; Paris & Alim, 2017). The purpose of this …

Becoming A Beloved Community: A Restorative Reckoning For A Radical Conversion To Transform Discourse In Higher Education, Latasha Tomay Varlack-Butler

Dissertations

This dissertation critically examines the misappropriation of Restorative Justice Discourse (RJD) within three predominantly white institutions (PWIs), analyzing 59 institutional documents through Critical Discourse Analysis, Relational Critical Discourse Analysis, and Rhetorical Criticism (Fairclough, 1995; Vaandering, 2021; van Dijk, 2008). Tribal Colleges and Universities and South African institutions have emerged as exemplars of authentic RJD, countering co-optation within PWIs. The findings demonstrate that RJD as applied in PWIs is framed in ways that attenuate its transformative potential, perpetuating color-evasiveness (Bonilla-Silva, 2017) and obscuring the intersectional experiences of Black, Indigenous, and disabled communities (Crenshaw, 1991; Million, 2009).

Grounded in decolonial praxis (Smith, …

Challenging Dominant Mindset Ideologies: Transforming Teaching And Learning That Impact Latinx Students, Francisco Lopez

Dissertations

Teacher identity poses a central connection to social justice education as researchers call for studies to pay attention to the cultural identities of those teaching in our schools when practices like color blindness are a common practice amongst teachers that keeps racial and social power intact. Despite the overwhelming presence of White teachers nationwide, we must pay attention to the specific needs of Teachers of Color in our classrooms. The assumption is often made that teachers of Color already have the knowledge on how to enact culturally responsive pedagogy. This study investigates the relationship between Critical Race Theory (CRT) and …

Restricted Access: Structural Gatekeeping And The Black Student Experience In Accounting Education, Richard W. Hurt Iii

Dissertations

This study explores the experiences of Black accountants as they reflect on their memories of the pipeline to their profession and the affective dimensions of their educational experiences as accounting majors in college. Grounding into Unapologetic Black Inquiry (UBI), a framework rooted in critical race theory, this investigation integrates narrative inquiry as a tool to capture rich descriptions from participant interviews and written reflections. Furthermore, this descriptive qualitative study explores how the structures and values of accounting education are rooted in a form of professionalism that prioritizes technical proficiencies over cultural knowledge, thus ignoring community forms of assets related to …

The Integration Struggles Of Myanmar/Burmese-Catholic Youth Refugees In The United States, Nant Thazin Shwe

Dissertations

ABSTRACT

Myanmar, previously known as Burma, generates a significant yearly refugee exodus stemming from ongoing ethnic conflicts, political instability, human rights violations, and the targeted persecution of Christian minority groups. Individuals seek shelter and improved opportunities in other nations. From 2011 to 2023, for example, Burmese refugees represented the largest group among U.S. refugee arrivals, accounting for 18 per cent.

Presently, there is a lack of knowledge about what the Burmese-Catholic youth refugees experiences during their integration journey into the US society. This qualitative study aimed to shed light on how the larger socio-cultural and religious environment intersects with Burmese-Catholic …

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 …

Understanding And Engaging In Equity Work: A Phenomenological Action Research Study Of Community College Esol Instructors, Emily E. Packer

Dissertations

Community colleges (CCs) are regarded as accessible and affordable pathways to higher education and financial mobility, offering significant potential to promote educational equity (Fink et al., 2023). These institutions enroll the largest number of English for Speakers of Other Languages (ESOL) students in adult education; however, CC ESOL students face lower rates of degree completion and transfer compared to their non-ESOL peers (David & Kanno, 2021; Fink et al., 2023; Raufman et al., 2019). While research has examined factors contributing to low CC ESOL student persistence and interventions to improve overall CC student outcomes, research on specific efforts to support …

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 …

Exploring A Holistic Conceptualization Of Destructive Leadership: Perspectives From The Lived Experiences Of Latino Law Enforcement Command Staff Officers, Carmelin Rivera

Dissertations

Recently, there has been an increased interest in destructive leadership or what is characterized as the dark side of leadership. There is, in fact, no consensus in the literature about the definition of destructive leadership, and this murkiness has led to two somewhat different approaches to understanding this phenomenon: 1) a leader-centric approach that emphasizes the bad behaviors and traits of so-called toxic leaders and 2) a much broader, holistic approach, often discussed as the toxic triangle (Padilla et al., 2007), that focuses on how destructive leadership is co-created by a toxic system of bad leaders and susceptible followers …

Walking The Tightropes: Tensions In High School Religious Education, Nicholas Hurt

Dissertations

This qualitative dissertation examined the challenges faced by high school religion teachers in Catholic education through interviews with 16 teachers from nine U.S. dioceses. The dissertation explored four key tensions the literature indicates have emerged in Catholic education since the Second Vatican Council: (1) balancing catechetical and academic approaches, (2) navigating the dual role of educator and minister, (3) reconciling prescribed curricula with diverse student needs, and (4) addressing training disparities and their impact on teacher morale.

Beyond these tensions, teachers identified additional challenges absent from the literature. First, they noted that nurturing authentic faith is difficult when students fear …

Exploring The Experience Of Embodiment Of Diverse Leaders, Susan Lynn Flaming Yeats

Dissertations

The experience of embodiment is a complex phenomenon that spans a range of feelings: a sense of connection to one's physical body, a sense of capability to accomplish certain physical acts, an attunement to self-care behaviors, a connection to desire, and inhabiting the body as a subjective site (Piran, 2016). This can be a complicated experience for leaders who hold multiple intersecting identities (Hill et al., 2016). As new medical therapies promise radical weight loss possibilities, the experience of embodiment has taken on a new layer of complexity (Giorgis, 2024). For fat leaders who are also women of color, sexual …

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

Dissertations

The COVID-19 pandemic led to unprecedented school closures, forcing administrators to take decisive action to radically change the educational system. The imperative to switch to remote learning transformed the dynamics of teaching and learning, leading to both immediate and long-term academic and social emotional consequences for all stakeholders. 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), …

How We Show Up Matters: Transformative Adult Social Emotional Learning To Build Equity-Centered Schools, Samantha L. Rummage-Massey

Dissertations

Transformative Social Emotional Learning (tSEL) expands traditional SEL by integrating equity and social justice to cultivate student development and as a framework for educator growth and systemic change in education (Jagers et al., 2019). Unlike traditional SEL, which primarily targets students, tSEL emphasizes educators’ role in disrupting inequitable practices, making it a powerful tool for reimagining schools as justice-oriented spaces. This qualitative case study explores how tSEL professional development influences educators’ sense of identity, agency, and belonging, along with their reflections on systemic inequities and application of Critical Pedagogy (Freire, 1970) in personal and professional contexts. Data collection included semi-structured …
