Background/Objectives: Oral potentially malignant disorders (OPMDs) require accurate risk stratification to identify patients at the highest risk for severe oral epithelial dysplasia (OED) or oral squamous cell carcinoma (OSCC). We developed and internally validated the oral cancer numerical index (OCNI), a quantitative risk score derived from clinical features and deep learning-based brush cytology measurements.

Methods: This retrospective model development and internal validation study was conducted using data from the multicenter Grand Opportunity study. Prospectively recruited subjects with OPMD with complete data were divided at the subject level into a training set (n = 384) and a holdout test set …

Surviving And Thriving: The Indigenous Migrant, Danna Guzman-Rodriguez

Honors Theses

This literature and cultural study highlights the generation of children of indigenous immigrants and the relationship with their indigenous identity and culture. This unique experience is complex and encapsulates issues such as indigenous cultural survival, homogeneity, globalization, and lack of cultural identity. Exploring the Totonac community in La Chaca, Veracruz in Mexico, allows for a deeper explanation of this experience. Speakers of Totonac and other indigenous languages often migrate to countries such as the United States and carry such cultural ties with them. What happens to these ties after moving to a Western-dominated country where globalization favors English and Western …

Optimization Of A Calb Catalyzed Esterification Process For The Synthesis Of Methyl Glucoside Fatty Acid Esters: Green Metrics, Application And Antimicrobial Evaluation, Abinash Nayak, Luana Carnaval, Swarna Jaiswal, Julie L. Dunne, Michael Kinsella, Claire M. Lennon

Research Outputs: 2025-Present

Carbohydrate fatty acid esters (CFAE) are promising sustainable antimicrobials with potential therapeutic applications. Although enzymatic synthesis of CFAE offers advantages, issues such as substrate solubility, limited exploration of non-classical greener solvents, additional synthetic steps, and analytical challenges hinder applicability and scale-up. In addition, mono-protected monosaccharide/unsaturated fatty acid (uFA) based CFAE are underexplored for antimicrobial evaluation. Our study systematically investigated the Candida antarctica lipase B (CALB) catalyzed esterification of methyl α-d-glucopyranoside (MAG) and lauric acid (LA) as a model system, employing green chemistry concepts to generate a panel of potentially more sustainable antimicrobial products. Systematic reaction optimization was followed by its …

A Qualitative Study Of Gratitude Practice Among Won Buddhist Older Adults And Implications For Gerontological Social Work, Sungsim Lee

Dissertations

Although gratitude has been widely studied in social science, existing scholarship has largely relied on Western worldviews and quantitative research frameworks, limiting understanding of lived gratitude experiences within diverse spiritual and cultural contexts, including Eastern spiritual traditions. In Won Buddhism, originating in South Korea, gratitude holds a central place in spiritual life and is understood as an essential practice. This qualitative study explores the views of Won Buddhist older adult practitioners regarding their experiences, benefits, and challenges of engaging in spiritually grounded gratitude practice. Semi-structured interviews were conducted with 23 practitioners aged 65 and older from English-speaking Won Buddhist communities. …

Being Desi At School: Exploring The Racialized School Experiences Of South Asian American Youth, Prabha Kaundinya

Dissertations

Schools in America have been central areas for racialization, and as an immigrant, racial-ethnic minority population, South Asian American (SAA) students have been subjected to a variety of racialization processes (S. J. Lee et al., 2017; Rice, 2017, 2019; Subedi, 2013). However, what is known about SAA educational experiences is often based on celebratory stereotypes that proclaim their uniform success while neglecting attention towards the diversity of their needs (including academic, social-emotional, or mental health needs; Saran, 2015; Ngo & Lee, 2007; P. Patel & Patel, 2017; Pedraza & Guillaume, 2023; N. Sharma et al., 2020). This dissertation uses a …

Making Sense Of The Barrio: Place-Based Appraisal And Coping Among Latine Residents In Chicago, Juanita Vivas Bastidas

Dissertations

Residents of Chicago’s Latine barrios often describe their neighborhoods as places of familiarity and safety—sites defined by both personal independence and collective solidarity, where daily life is marked by a sense of belonging and mutual support. Yet, residents also contend daily with overlapping social and environmental stressors. While urban, medical, and environmental sociologists have each shown that place matters, their findings remain siloed and rarely integrated to illuminate the everyday realities of Latine neighborhoods. As a result, we lack a systematic analysis of how people living in Chicago’s Latine barrios make sense of and cope with multiple, simultaneous stressors. I …

Responsive Rigor And Strategic Care: Faculty Praxis For Holistic Student Success In The Community College, Jennifer Elizabeth Kelley

Dissertations

This qualitative study examines how community college faculty conceptualize, communicate, and enact academic rigor and care in their teaching practice. While post-pandemic debates have positioned rigor and care as opposing forces—evident in the "Rigor Wars" that framed care as performative laxity and rigor as gatekeeping—community college faculty successfully integrate these practices to support holistic student success. This research addresses critical gaps in higher education scholarship, which has studied rigor and care separately, focused primarily on four-year institutions, and overlooked faculty perspectives on how integration occurs in practice. Drawing on a single-case study of 38 faculty members at a large Midwestern …

The Year Of Birth Age Grouping Policy: Its Impact On Participation In Us Youth Soccer, Murray James Findlay

Dissertations

In 2016, the United States Soccer Federation (USSF) implemented a nationwide year-of-birth (YOB) age grouping policy that aligned youth soccer teams with calendar years (January 1st –December 31st), replacing the traditional schoolyear (August 1st –July 31st) grouping system. This dissertation investigates the impact of that policy on youth soccer participation in the United States, addressing a critical gap in empirical research linking national policy interventions to participation outcomes. Framed through the Fun Integration Theory (FIT) (Visek et al., 2015), which conceptualizes youth sport engagement as driven by social and intrinsic enjoyment factors, the study examines whether the YOB policy caused …

“Being An Arab Is Like Fighting For Your Joy”: Exploring Bicultural Identity, Racialization, And Psychological Well-Being Among Us-Born Arab Americans, Hisham Nsier

Master's Theses

Bicultural identity development in Arab Americans, who must manage sometimes conflicting cultural expectations, is understudied. Even less is known about Arab Americans born in the United States (US-born AA), who are American by birth yet are alienated from society due to differences between their ‘white’ racialization and their cultural identities. The current study aimed to examine the relationship between bicultural identity, racialization, and psychological well-being at the intersection of US-born AA’s co-existing identities. Eight adult US-born AAs (Mage = 28 years, SD = 4) were recruited from professional Listservs and WhatsApp affinity groups. Qualitative semi-structured interviews were conducted and analyzed …

Articulating The Future: How The Techno-Optimist Manifesto Constructs Ai Hegemony, Christian Noel Yeomans

Master's Theses

This paper analyzes two recently published digital manifestos—the Techno-Optimist Manifesto (TOM) by Marc Andreessen and the Bitcoin Whitepaper (BW) by Satoshi Nakamoto—and how they articulate political visions for the respective rising technologies of artificial intelligence (AI) and cryptocurrency. I apply Laclau and Mouffe’s discursive articulation theory to both manifestos, analyzing how they contribute to the formation of hegemonic ideological visions among the elites of these two technological sectors. In the context of AI elites, TOM transforms an existing Silicon Valley ideology, techno-optimism, into a radical new form of accelerationism, which I coin t/opt. This shift is examined within the context …

Counting Your Chickens Before They Hatch: Understanding Anticipatory Savoring And How And Why People Approach Or Avoid The Anticipation Of Future Positive Events, Asura Louise Osborne

Master's Theses

In this study, discretion between the styles used to anticipate positive events is the focus of a Confirmatory Factor Analysis (CFA) conducted on the Index of Anticipatory Styles (IAS). The IAS is a 45-item survey used to measure types of savoring in response to future positive events. This work expands the savoring literature to examine approach- and avoidant-type anticipatory savoring. Approach-type anticipatory savoring discriminates between Enjoyment, Coping, Control, Recalled Anticipation, and Downplaying. Avoidant-type savoring parses between Avoidance of anticipation because events may not occur, Avoidance of anticipation because events may fail to live up to expectations, Jinxing, and Counterproductivity. CFA …

Growing Through Systemic Adversity: Evaluation Of Developmental Trauma Assessment Among Black And/Or Latiné Adolescents With Adhd, Victoria Grant O'Daniel

Master's Theses

Black and Latiné youth are disproportionately impacted by targeted harm and trauma exposure, which is further exacerbated by stigma, biases, and punitive actions towards youth with attention deficit/hyperactive disorder (ADHD). This presents an urgent public health concern, as frequent exposure to trauma across development can lead to difficulties with behavior regulation, interpersonal relationships, impulse control, emotion regulation, and attention and cognition. Developmental trauma disorder (DTD) was proposed to capture the adverse developmental outcomes experienced by youth exposed to chronic trauma; however, there is a dearth of research on how to assess DTD. Thus, the current study aimed to establish support …

Identity Conflict In Student-Athletes: Athletic And Academic Identity Salience As Predictors Of Stress, Alaina Abel

Master's Theses

The goal of the current research is to explore the dual identities of collegiate student-athletes. More specifically, it aims to examine how the salience of the two identities may impact identity conflict and stress levels. Balancing the demands of academics and athletics presents unique challenges to this population. Academically, time constraints, missed classes, pressure to maintain GPA, and mental fatigue present barriers to academic success, while athletically, rigorous training schedules, frequent travel, and the pressure to perform consistently present obstacles to excel in their sport. The constant tug and pull between balancing the responsibilities of two roles that significantly shape …

Pubertal Timing, Physical Activity, And Internalizing Symptoms In Adolescent Girls, Kirby Knapp

Master's Theses

Puberty brings marked changes in physical appearance, biological functioning, psychological well-being, and behavior, making it one of the most pivotal transitions in adolescence. Those who experience puberty earlier than their same-aged peers are at an elevated risk of psychological disorders and physical inactivity. Research shows that there are links between physical activity and psychological disorders, yet few have examined the directional relations between physical activity and internalizing symptoms or whether a certain amount of physical activity is necessary to prevent internalizing symptoms. Therefore, the current study examined (1) the directional relations between internalizing symptoms and physical activity, (2) the degree …

Doctoral Dissertations and Projects

This qualitative descriptive case study described the perceptions of school-based mental health (SBMH) professionals and school resource officers (SROs) regarding personal and campus safety in the presence of an SRO. Guided by routine activity theory (Cohen & Felson, 1979), which framed SROs as capable guardians within schools, and relational cultural theory (Miller, 1976), which emphasized connection and collaboration, the study examined how relational dynamics influenced safety perceptions and well-being. Participants from K–12 public schools in North Central Arkansas contributed data through semi-structured interviews, focus groups, and the Georgia School Personnel Survey of School Climate. Reflexive thematic analysis identified key themes …

The Impact A Lack Of Racial/Ethnic Diversity Has On Spiritual Formation And The Key Actions Necessary For Resolution, Kimberly Janelle Baker

Doctoral Dissertations and Projects

The problem this research addresses is that New Community Church, a local church ministry, lacks a racially/ethnically rich and diverse spiritual formation experience. A lack of racial/ethnic diversity within churches nationwide is a pervasive issue. While some churches are not more diverse due to location, there are many, including the specific church chosen to be included as part of the problem statement, that are located in diverse communities but still do not adequately reflect the racial/ethnic make-up of their respective communities.

Martin Luther King Jr., once said that “It is appalling that the most segregated hour of Christian America is …
