Why Families Stay Or Leave: Experiences In Spanish-English Dual Language Immersion Programs, Rachel L. Hall

All Dissertations

Many school districts across the United States offer dual language immersion (DLI) programs where students learn academic content in two languages, most often English and Spanish. These programs are designed to help students become bilingual and biliterate while also building cultural awareness and appreciation. Although DLI programs continue to grow in popularity, less is known about why some families stay in these programs while others choose to leave. This study examined enrollment and retention patterns in Spanish-English DLI programs in a suburban school district in North Carolina. Using a mixed methods approach, the study combined district enrollment data, parent surveys, …

“Do We Belong?”: Supporting Culturally And Linguistically Diverse Students Through Teacher Education, Morohunkeji Orija

All Dissertations

The population of students from diverse cultural and linguistic backgrounds in K-12 education continues to increase, yet the teacher workforce remains largely homogeneous, predominantly White. This imbalance creates a cultural mismatch in educational settings. In teacher education, predominantly White teacher educators prepare predominantly White preservice teachers, further increasing this mismatch. In early childhood education (ECE), which spans birth to 8 years, racial mismatch can lead to misunderstandings and misconceptions, contributing to bias and manifesting as Racial Microaggressions (RMAs). RMAs are mostly unintentional, and research is needed to examine how preservice teachers can identify and address them, given their impact on …

Abnormal Trafficking And Processing Of Multiple Matrix Metalloproteinases Drive Cartilage Defects In Congenital Disorders Of Glycosylation, Chia-Lun Wu

All Dissertations

Congenital Disorders of Glycosylation (CDG) are rare metabolic diseases caused by defects in glycosylation. Despite identification of over 200 CDG types, the mechanisms linking glycosylation defects to diverse clinical phenotypes remain unclear. This dissertation uses zebrafish models of PMM2-CDG and STT3-CDG to redefine CDG pathogenesis, shifting from a simple glycan deficiency model to one involving disrupted cellular spatial organization.

We identify a protease-dependent pathway underlying craniofacial cartilage defects. Specifically, defective proteolytic processing of N-cadherin, a key adhesion molecule in chondrogenesis, is a central driver of pathology. We further uncover an unconventional trafficking mechanism in which ER stress and altered secretory …

Virtual Reality In Informal Education: Trends, Frameworks, And Implementation Strategies, Allison Maynard

All Dissertations

The rapid evolution of immersive technologies presents informal education settings with a complex dual challenge: while virtual reality (VR) offers compelling opportunities for engagement and experiential learning, its adoption demands significant institutional resources and may require a meaningful departure from established interpretive practice. As informal education institutions face decisions about whether to adopt emerging technologies, a critical gap remains in understanding how VR should be designed and integrated to serve both organizational missions and the needs of frontline interpreters and audiences. This dissertation moves beyond the technical novelty of VR to empirically examine its purposeful positioning within informal education settings, …

"Because You Speak Two Languages": Latino Immigrant Families Negotiating Language Ideology, Liminality, And Education In Arkansas, Cindy Rauth

Graduate Theses and Dissertations

This dissertation presents a critical ethnographic study of lower socio-economic status, multilingual Latino immigrant families in one region of Arkansas, which has undergone rapid demographic changes in the last four decades. As the Latino population has grown, schools have struggled to accommodate the needs of their diverse students and families, which has contributed to below-grade-level literacy skills and significant student disengagement. This study examines students’ schooling experiences from the perspective of the family. Through an interdisciplinary approach, this study explores three interconnected themes: family experiences of schooling, language ideology, and liminality. A comprehensive examination of family educational experiences includes the …

From Synapse To Circuit: Mechanisms Of Behavioral Flexibility And Its Restoration After Prenatal Alcohol Exposure, Jayapriya Chandrasekaran

Biomedical Sciences ETDs

Behavioral flexibility—the ability to adapt behavior when contingencies change—is a fundamental executive function supported by orbitofrontal–striatal circuitry. This dissertation examined molecular, motivational, and circuit mechanisms underlying flexibility and its restoration after prenatal alcohol exposure (PAE). In healthy mice, GluN2B-containing NMDA receptors in the orbitofrontal cortex increased during outcome updating, while AMPA receptor subunits in the dorsal striatum rose during new learning, defining temporally distinct plasticity processes. PAE impaired reversal learning under low-reward conditions, but not when motivation was high, indicating altered thresholds for circuit engagement rather than permanent loss. Finally, optogenetic stimulation of OFC→dorsal striatum projections rescued flexibility in PAE …

Without Their Consent: The History Of Involuntary Sterilization Of Women Of Color In The United States, Guadalupe Cataldo

Women's, Gender, and Sexuality Studies

Throughout the history of the United States, there is a continuous theme of women of color and immigrant women experiencing violations of their reproductive rights, including sterilization abuse. Under eugenics laws and initiatives, these women have been sterilized to prevent the reproduction of people that those in power deemed “unfit.” Due to intersecting gender, racial, and socioeconomic statuses, women of color have been more vulnerable to involuntary sterilization than their more privileged peers. Through the review of research articles, analysis of documentary interviews, collection of relevant news articles, and archival research of materials produced by organizations fighting sterilization abuse, this …

How Academic Pressure Is Declining The Mental Health Of South Korean Students, Lilyanne Boyland

East Asian Studies

South Korea’s education system is widely recognized for its academic excellence; however, this may highly impact students’ mental health and overall well-being, which can hinder their academic performance. Students are known to dedicate long hours of their day to their education, in addition to their daily academic schedules. This study focuses on how academic pressure, that is mostly driven by parents and educators, as well as traditional cultural values on education, affects the mental health of South Korean students. This thesis is divided into three sections: Historical and Cultural Contexts, South Korea’s Current Educational Environment, and Next Steps for South …

Intersectionality And Belonging: Higher Education Mathematics, Ashley Natalie

Mathematics and Statistics

Students with intersecting marginalized identities (such as race, gender, socioeconomic status, disability, or first-generation background) often face unique challenges in advanced mathematics that affect confidence, participation, amounting to a sense of belonging. These experiences remain underrepresented in mathematics education research. This qualitative, narrative-based study examines how these students experience classroom dynamics and belonging in upper-level mathematics courses. Semi-structured interviews will be analyzed thematically to identify patterns related to identity, classroom culture, instructor behavior, and peer interactions. Findings aim to highlight barriers and supportive practices, informing more inclusive teaching strategies and equitable learning environments in advanced mathematics.

Youth In Leadership Positions: A Mediation Program Proposal, Abigail Horn

Sociology

Encountering the justice system can have harmful impacts on a child’s well-being and can lead to negative outcomes in the future, such as missing school and reoffending. This paper proposes a program to combat these impacts by creating infrastructure for schools to handle low level offenses within schools through a mentoring program. After a review of the literature on the current justice system in the United States, rehabilitative and restorative justice practices, and the effects of youth leadership positions, the “Re-Mentoring Program” is proposed. A play on the words "restorative" and "rehabilitative," this program involves youth who have offended, victims, …

Rethinking The Scope Of State Power: Territorial Jurisdiction, Popular Sovereignty, And Extraterritorial Legislation, Jeffrey Schmitt

William & Mary Law Review

The Supreme Court applies the territorial framework of international law to resolve disputes over the reach of state power. Under this framework, a state’s power is coterminous with its borders, such that a state’s regulatory power within its territory is limited only by federal law. The Court recently used this framework to overrule an obscure line of Dormant Commerce Clause cases that held that a state regulation of local conduct could have impermissible extraterritorial effects.

This Article argues that the territorial model of state power from international law does not account for the division of sovereignty within our federal system. …

Too Cruel For School: How Parental Rights Doctrine Can Help Protect Against Book Bans, Tessa K. Wild

William & Mary Law Review

This Note argues that parents’ rights protections are crucial to protecting against broad censorship in public schools, and that if states want to effectively regulate book removals, they should preemptively adopt laws similar to Minnesota’s section 134.51.

[...]

Part I of this Note will provide background information about book removals as a freedom of speech issue, as well as a history of how parents’ rights rhetoric is tied to book-removal issues. Part II will address both the history and legal standards of parents’ rights protections. Finally, Part III, using Minnesota and Utah as case studies, will apply parents’ rights law …

Evaluating The Psychometric Validity Of Science Curiosity, Brooke Simila

Graduate Theses and Dissertations (2019 - present)

As political polarization and mass distrust in scientific consensus increases, psychologists have sought to understand individual differences that contribute to polarized political and scientific reasoning. One emerging concept in this area is science curiosity (SC), the disposition to seek and engage with scientific information for personal gratification (Kahan et al., 2017). A handful of studies have identified SC as an offsetting variable in politically motivated reasoning (Motta et al., 2021). However, the psychometric structure of SC remains underexplored; it is unclear whether SC represents a distinctive, unidimensional disposition or merely a manifestation of general curiosity traits. The purpose of this …

Narcissism And Eyewitness Identification, Haley M. Hearn

Graduate Theses and Dissertations (2019 - present)

According to the Innocence Project, 69% of individuals exonerated by DNA evidence were initially found guilty due to an eyewitness misidentification (Innocence Project, n.d.-a). A way that investigators attempt to prevent misidentification is by assessing how confident eyewitnesses are in their identifications. There is a large body of research suggesting that these confidence estimates can, in many instances, operate as reliable barometers of accuracy. However, what if an eyewitness is overconfident? Narcissism is a personality trait characterized by overconfidence. If a narcissistic eyewitness reports confidence in their identification of a suspect, should this report be trusted? Two studies were conducted …

Big Feelings, Fast Decisions: Emotion Regulation As A Moderator Of Impulsivity In Binge And Emotional Eating, Emma G. Folk

Graduate Theses and Dissertations (2019 - present)

Emotion-driven impulsivity and difficulties with emotion regulation are both associated with maladaptive eating behaviors, including binge eating and emotional eating. However, it remains unclear whether broader emotion regulation difficulties intensify the influence of impulsive responses to emotional states on these behaviors. This study examined whether emotion dysregulation moderates the relationship between emotion-driven impulsivity and maladaptive eating behaviors. Participants were 266 adults (ages 18–65) who completed measures of impulsivity, emotion regulation difficulties, binge eating, and emotional eating. Moderation analyses were conducted using PROCESS in SPSS, controlling for body mass index (BMI) and gender. Negative and positive urgency were significantly associated with …

Generalized additive mixed-effects models were used to test the associations between perceived socioenvironmental neighborhood attributes and daily step counts. …

Addressing Nonignorable Missing Data And Heterogeneity In Prognostic Biomarker Assessment, Xinran Huang, Ruosha Li, Jing Ning, For The Alzheimer's Disease Neuroimaging Initiative

Faculty, Staff and Student Publications

Covariate-specific and time-dependent area-under-curve (AUC) is often used to evaluate the discriminative performance of biomarkers with time-to-event outcomes, particularly when certain covariates influence biomarkers' accuracy. In biomarker research, despite extensive efforts, missing data remain unavoidable, with nonignorable missingness posing significant challenges. This article focuses on estimating the impact of covariates on time-dependent AUC in the presence of nonignorable missing biomarkers. Assuming a parametric model on the missing probability, we leverage instrumental variables to address the identifiable issue and estimate the unknown parameters. We integrate the inverse probability weighting approach into the score equation of a pseudo partial likelihood for estimation …
