Faculty, Staff and Student Publications

Background and objectives: The apolipoprotein E (APOE) haplotypes are known to be associated with dementia, with the ε4 haplotype associated with higher risk. It has been suggested that the APOE ε2 allele serves as a protective factor for dementia. However, data on the effects of the homozygous APOE ε2/ε2 genotype are limited, likely due to the rarity of the APOE ε2/ε2 genotype. Furthermore, the association between APOE genotypes and dementia may differ across self-reported race. We aim to investigate the association between APOE genotypes and dementia overall and across self-reported race, with a focus on the potential protective …

Beyond Beliefs: Factors That Shape Agricultural Plastic End-Of-Life Management Among California Strawberry Growers, Kyle Y. Cahitas

Master's Theses

The practice of using plastics in agriculture is so prevalent it has earned its own name: plasticulture. One key plasticulture tool is polyethylene (PE) mulch film, a thin plastic sheet laid over the field for a single growing season and pulled out before the next. Because PE film is hard to recycle, most of it ends up in a landfill, yet how growers decide what happens to used plastic mulch has rarely been studied. To identify what shapes that decision, this study draws on a survey of California strawberry growers (n = 126). Twenty variables, spanning grower attitudes, farm characteristics, …

From Margins To Center: Los Deslenguados In The Borderlands, Brissa S. Porras Villalobos

Electronic Theses, Projects, and Dissertations

Borderland literature is a subgenre that often includes narratives of migration, tribulations, identity development, and resilience. It foregrounds the collaboration of vulnerability, isolation, connection, and power, showing that hybridity is a source of cultural energy. Acknowledging the borderland and its culture is crucial because it challenges stereotypes, validates marginalized voices, and celebrates heritage in all its complexity. By centering these experiences, borderland literature affirms the potential of living between cultures, prioritizing the recognition of the in-between, valuing and celebrating the space where identities are continually reshaped, histories are reclaimed, and resilience is nurtured rather than neglected. Using Gloria Anzaldúa's theory …

The Relativity Of Education: Student Perspectives On Artificial Intelligence In Community College, Ashley Greta Magana

Electronic Theses, Projects, and Dissertations

This hermeneutic phenomenological study examined how diverse community college students experience and make meaning of the integration of generative artificial intelligence (AI) into their educational contexts. Although AI is quickly transforming higher education through automated grading, personalized learning systems, and new models of assessment, the discourse surrounding its implementation remains dominated by administrators, faculty, and institutional stakeholders, while the perspectives of students, specifically community college students who are often historically underrepresented and economically marginalized, are systematically excluded. Most existing research is quantitative and centered on universities, leaving a critical gap in qualitative understanding of the most diverse population in higher …

A Culturally Responsive Sexual Health Education Framework For Community Clinics In The Inland Empire, Lilianna Mora Ledezma

Electronic Theses, Projects, and Dissertations

Sexually transmitted infections (STIs) continue to disproportionately affect underserved communities, where barriers such as limited healthcare access, stigma, healthcare anxiety, medical mistrust, and language differences may discourage individuals from seeking routine screening and timely treatment. This project examined current public health literature, surveillance data, and federal guidance to identify evidence-based strategies that community clinics can implement to improve patient engagement in sexual health services. The findings demonstrated that effective STI prevention extends beyond testing alone and is strengthened through culturally responsive care, stigma reduction, patient-centered communication, standardized clinic workflows, and effective patient navigation. As a result, this project developed a …

The Effect Of Telehealth Expansion On The Health Equity Of Underserved Populations, Mansi B. Satani

Electronic Theses, Projects, and Dissertations

The rapid expansion of telehealth, during and after the COVID-19 pandemic, has changed healthcare delivery in the United States. The use of telehealth can potentially decrease disparities related to isolation, shortage of providers and barriers to transportation, however, its impact on health equity in underserved populations is unknown. This paper explores how telehealth expansion impacts rural populations' access to healthcare, health outcomes, and equity. It also examines its impact on populations with low income, racial, ethnic minorities, and Medicaid recipients who frequently encounter obstacles to healthcare and digital access (Nouri et al., 2020; Shah et al., 2024). A mixed-method design …

Role Of Stigma On Engagement In Mental Health Services For Latinxs With First-Episode Psychosis (Fep), Livia J. Padron Briceno

Electronic Theses, Projects, and Dissertations

Psychotic patients often endure stigma in their daily lives (Corrigan, 2018). Psychotic patients are understood as individuals who are experiencing psychotic symptoms such as hallucinations, delusions and disorganized speech (Arciniegas, 2015; Breitborde et al., 2017; Moskowitz et al., 2019) and have been diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria with a psychotic disorder (e.g. Schizophrenia, Schizoaffective Disorder). Stigma refers to negative perceptions held about an individual experiencing mental illness. While public stigma refers to the negative views adhered to by members of communities (e.g., sociocultural group, family units) about people with mental illness, self-stigma …

The Third Zone Of Incomplete Rights: Spatial Compartmentalization, Expendability, And The Making Of Death Worlds In Adichie's Dream Count, Ebelenna F. Nwaobi

Research Papers

Contemporary socio-political discourses on global migration often risk misrepresenting migrant experiences by framing them mainly through the language of humanitarianism, inclusion, and identity. While these frameworks foreground protection and belonging, they may inadvertently obscure the institutional and political structures that regulate, differentiate, and expose migrants to uneven forms of precarity. In this paper, therefore, I examine Chimamanda Ngozi Adichie's Dream Count to explore the migrant condition as one shaped by migrants’ everyday encounters with space, law, labor, and political belonging. By so doing, I argue that the novel reveals migrant vulnerability not just as the consequence of singular acts of …

Laplace Factor Models In High-Dimensional Data, Siqi Liu, Xuerong Meggie Wen, Akim Adekpedjou, Guangbao Guo

Mathematics and Statistics Faculty Research & Creative Works

Laplace factor models (LFMs) provide a heavy-tailed alternative to Gaussian factor models by representing high-dimensional observations through a low-rank common component and Laplace-distributed idiosyncratic errors. This paper develops an assumption-consistent finite-sample analysis of matrix concentration, covariance estimation, and Monte Carlo integration under this model. We first formulate the model with explicit dimensional, independence, covariance, and identifiability conditions. Standard matrix Laplace-transform and matrix Bernstein inequalities are then recalled with their precise applicability conditions. Because untruncated Laplace variables are neither almost surely bounded nor strongly log-concave, these standard results cannot be applied directly in the forms commonly used for bounded or Gaussian-like …

Unruly Curly Hair: The Role Of Latina Hair Stylists In Disrupting Beauty Hierarchies, Katie Duarte

Latin American and Latino/a Studies: Faculty Publications

Women of color use aesthetics to challenge and reproduce racialized, classed, or gendered marginalization, yet few sociological studies have examined women of color service workers as agents who negotiate, reproduce, and resist racialized beauty norms for their clients. This study utilizes a transnational ethnography of a beauty school course and Latina-owned curly and natural hair salons, primarily serving Latinas and Afro-Latinas, in New York City and Santo Domingo, Dominican Republic. Through its analysis, this article identifies different forms of gendered labor that stylists perform to introduce “specialized body labor,” thereby disrupting racialized beauty norms that devalue natural and Afro-textured hair. …

A Misplaced Pocket Of Air: Intramural Gastric Air Most Consistent With Gastric Emphysema, Priyanka Panwar, Lavender Otom, Subo Marsa, Gerald Odong, Steven Idet, Irene Muchiri, Hussein Abdulsamad, John Odhiambo, Christopher Opio, Amos Mwasamwaja, Saleem Abdulkarim

Internal Medicine, East Africa

Background Gastric emphysema (GE), or gastric pneumatosis, is a rare, noninfectious cause of intramural gastric air that must be distinguished from emphysematous gastritis (EG), a highly lethal infectious entity. Despite similar radiographic appearances, these conditions differ substantially in etiology, clinical course, management, and prognosis.

Cases We report three hemodynamically stable patients with CT-confirmed intramural gastric air most consistent with GE. Two had associated portal venous gas. The cases occurred in distinct clinical contexts: infectious gastroenteritis with retching, transient midgut volvulus with obstructive gastric overdistension, and alcohol-related upper gastrointestinal bleeding with forceful vomiting and a Mallory–Weiss tear. Although early EG could …

Chronic absenteeism continues to be a growing concern in high schools, particularly in the years following the COVID-19 pandemic. Although family involvement has been widely studied in elementary and middle schools, less is known about how families and mathematics teachers experience school-based family involvement at the high school level. This qualitative case study explored those perspectives at a rural high school in Northwest Georgia. Individual semi-structured interviews were conducted with five families and five upper-level mathematics teachers, and a focus group was conducted with eight mathematics teachers. Interview and focus group transcripts were analyzed using structural and focused coding to …

Park Visitor Education And Landscape Conservation: Evaluating Education-Based Strategies To Mitigate Visitor-Caused Damage In Goblin Valley State Park, Jason Beukers

All Graduate Reports and Creative Projects, Fall 2023 to Present

Goblin Valley State Park contains rare and highly fragile geological formations that are increasingly impacted through visitor-caused damage. While the park’s open-range management approach enhances recreational freedom and the visitor experience, it also leaves vulnerable hoodoo formations susceptible to vandalism and damage by visitor behavior and exploration. Balancing public access with landscape preservation remains a persistent challenge, particularly in large, protected areas where staffing, enforcement, and management resources are limited. This thesis reviews the effectiveness of management strategies, particularly education-based strategies such as signage and visitor messaging, in reducing depreciative visitor behaviors in national and state parks and other protected …

Language Learning Under Pressure: Rethinking Anxiety, Assessment, And Support In Second Language Classrooms, Bryn C. Cole

All Graduate Reports and Creative Projects, Fall 2023 to Present

This portfolio examines the role of anxiety in second language acquisition (SLA) and its impact on student performance, assessment, and overall participation. Drawing on both the author’s classroom experience and SLA research, it argues that language anxiety should be understood as a structural feature of classroom environments rather than an individual learner deficit. The paper explores how traditional assessment practices may obscure students’ underlying competence by prioritizing performance under pressure. It proposes two key shifts in response: reformatting assessments as a more flexible and context-sensitive process, and integrating peer mentorship as a form of interpersonal instructional support. Together, these approaches …
