Social Capital In The Puerto Rican Deaf Community, Javier Figueroa Quintana

Theses and Dissertations from DePaul University

There is limited literature regarding the social capital of deaf individuals in the United States (U.S.). There are few studies on deaf individuals in Puerto Rico (P.R.), and none explicitly examines deaf Puerto Ricans’ social capital. This qualitative study aimed to understand and capture the experiences of the deaf Puerto Rican community by focusing on how deaf Puerto Ricans utilize social capital to achieve success. The two main research questions guiding this study are: How have deaf Puerto Ricans utilized social capital to achieve success? What are deaf Puerto Ricans' perceptions of success? This study centers around Yosso's (2005) Community …

Redefining Retention: Analyzing The Experiences Of Black Men In Higher Education Through The Lens Of Race, Masculinity, And Strength-Based Approaches, Roderick Waters

Theses and Dissertations from DePaul University

Black male students have continued to face systemic challenges in higher education, particularly at historically White institutions (HWIs), where they experience lower retention and graduation rates compared to their peers. Although enrollment numbers have increased, institutional barriers, racialized campus environments, and deficit-based narratives have continued to contribute to disparities in academic success. Much of the existing research has focused on the challenges Black male students encounter rather than the strategies, relationships, and institutional conditions that support their persistence. This study sought to shift that focus by exploring the lived experiences of Black men who persisted at an HWI through an …

The Impact Of Leadership Of International Baccalaureate Schools In Low Socio-Economic Communities, Sheena Wallker-Carruthers

Theses and Dissertations from DePaul University

The International Baccalaureate (IB) has expanded rapidly into schools serving low socioeconomic status (SES) communities in the United States as part of broader efforts to increase access to rigorous, internationally recognized academic programming. While research has documented positive student outcomes associated with IB participation, less is known about the leadership conditions that support the long-term sustainability of IB programs in under resourced contexts. This quantitative, cross-sectional study examines IB leaders’ perceptions of implementation and sustainability challenges in low-SES school settings, the relationship between those challenges and perceived leadership effectiveness and program outcomes, and the adaptive strategies leaders identify as essential …

The Moderating Effect Of Gender And Humor On Leader Evaluation, Russell John Marshall

Theses and Dissertations from DePaul University

There has been much discourse in the popular press, political, and professional spheres about the humor used by leaders and aspiring leaders. Although humor is seen as mostly positive in the workplace, there have been significant findings that humor’s impact is influenced by gender/sex. Male humor use is often seen as functional, while female humor use is seen as disruptive (Evans et al., 2019). This study examines how humor and gender/sex affects likeability and professional respect for leaders. It was predicted that humor use would increase male leaders likeability and professional respect while decreasing these rating for female leaders. Participants …

Behavioral Strategies And Mental Health Reactions To Social Preference Insecurity: The Effect On Social Preference And The Moderating Role Of Machiavellianism, Alexandra Zingarelli

Theses and Dissertations from DePaul University

Adolescents experience insecurity about social preference; however, its role in adolescent behavioral and mental health and subsequent social preference has not been studied. Additionally, individual differences in personality further contribute to adolescent’s behavioral and mental health development and subsequent peer liking. Using a longitudinal and muti-informant design, the present study examined whether social preference insecurity (SPI) predicted social preference through the mediation of aggression and depression and examined whether Machiavellian traits moderated these pathways among 817 adolescents (Age: M=12.19 SD=0.813, Male: n=409, 50%; Female: n=409, 50%) from middle schools in the U.S. Midwestern states. The results showed that Time 1 …

The Perceptions Of Early Adolescents: Academic Stressors Within Under-Resourced Schools, Problem Solving, And Important Adults, Aliyah White

Theses and Dissertations from DePaul University

Early adolescence is marked by increasing academic demands and the growing need for effective coping strategies. The present study examined early adolescents’ perceptions of academic stressors, use of primary control coping mechanisms, and identification of important related and unrelated adults within their lives. Participants included 96 youth ages 10-14 recruited from Chicago Public Schools in under-resourced South Side communities. Results indicated that youth reported substantial exposure to academic stressors, including teachers yelling, difficulties understanding coursework, and pressure to perform well academically. Findings revealed a significant decrease in the use of primary control coping strategies over time, despite increasing academic stress. …

The Impact Of Social Support On Somatic Health Symptoms In Emerging Adults: Examining The Role Of Cortisol And Cytokines, Autumn Sharon Rajcevich Schwer

Theses and Dissertations from DePaul University

There is a wealth of previous research demonstrating that increased levels of social support are associated with mental health benefits, with several potential pathways supported, including social support leading to increased emotional comfort and resilience (Mohan et al., 2024). However, research also demonstrates that increased social support is associated with numerous physical health benefits as well, including lowered risk of chronic disease development and longer lifespans (Hale et al., 2005). But there seems to be a gap in research regarding how social support creates this positive physiological effect. The present study aimed to address this gap and investigate the potential …

Exploring The Roles Of Grit And Health Anxiety In The Relationship Between Discrimination And Pain-Coping Among Adolescents And Young Adults, Giselle Mcpherson Isbell

Theses and Dissertations from DePaul University

Chronic pain is a complex and highly prevalent concern that can significantly disrupt functioning during adolescence and emerging adulthood. Pain during this developmental period may interfere with academic engagement, social relationships, emotional functioning, and the transition toward independence. Psychosocial stressors such as discrimination and heightened health anxiety may negatively influence pain experiences and coping, whereas protective psychological characteristics such as grit may buffer these effects. The present study examined the relationships between discrimination, health anxiety, grit, pain outcomes, and coping strategies in emerging adults with chronic pain. Participants completed self-report measures assessing discrimination, health anxiety, grit, pain intensity and frequency, …

Mapping The Landscape Of Occupational Health Psychology Research On Immigrant Workers: A Systematic Review, Himali Bhandari

Theses and Dissertations from DePaul University

Research on immigrant populations covers a wide range of topics including immigrationpatterns, demographics, working conditions, and occupational health. Nevertheless, studies specifically on immigrant workers within occupational health psychology (OHP) are scattered. To address this inconsistency, this systematic review analyzed OHP research focusing on immigrant workers, highlighting key immigrant characteristics and the psychological theories and frameworks used to explain why and how immigrant workers face high occupational health and safety risks. Peer-reviewed empirical articles were retrieved from APA PsycINFO, APA PsycArticles, and Academic Search Complete using a predefined set of search terms. Qualitative analysis of the included studies (N = 44), …

Silent Or Silenced? A Systematic Review Of Deaf And Hoh Workers In Io Psychology Research, Lora Bishop

Theses and Dissertations from DePaul University

Deaf and Hard-of-Hearing (DHH) workers report routinely missing workplace information that hearing colleagues receive through informal and ambient channels, as well as constrained participation in environments where communication norms treat hearing as the default. Despite over a century of research, this literature remains largely outside flagship industrial-organizational (IO) psychology journals. This dissertation conducts an integrative systematic review of 48 empirical studies published between 1919 and 2025, examining workplace outcomes and methodological patterns, the theoretical frameworks deployed, sampling and reporting practices, and the framing and identity-language conventions through which the literature engages DHH workers. The review appears predominantly in WORK and …

Ready To Serve, Spencer Hillier

The Diana McDonald Writer's Challenge

In this thorough analysis of the U.S. military’s ban on transgender personnel, Spencer Hillier describes the great sense of pride he felt when he initially joined the Army National Guard, as well as his subsequent emotional struggle, not to mention loss of GI benefits, health and dental insurance, and retirement benefits due to the 2017 ban on transgender service members. Hillier takes a careful look at the arguments against transgender personnel, developing thoughtful, logical explanations of why they lack validity. He argues that what matters is not a person’s identity, but whether one can fulfill the seven Army values—loyalty, duty, …

Valuing Biodiversity Impact, Han Wei Koh

Dissertations and Theses Collection (Open Access)

Biodiversity loss has emerged as a systemic challenge with far-reaching implications for ecological stability, economic activity, and long-term financial resilience. Despite growing recognition of nature-related risks in finance, biodiversity remains far less developed than climate within investment analysis, particularly at the portfolio level. This dissertation addresses that gap by examining how biodiversity impacts can be measured, valued, and interpreted within an investment portfolio concentrated in resilient and essential sectors of the economy.

The study constructs a Global Essential Economic Systems Portfolio comprising 16 publicly traded companies operating across non-discretionary sectors, including agriculture, energy, materials, pharmaceuticals, utilities, infrastructure, telecommunications, and financial …

The Impact Of Spatial Disparities On Transportation To Dialysis: A Quantitative And Gis Analysis, Haylee Kirschner

Social Work Doctoral Dissertations

Access to dialysis treatment is a major concern for the over 500,000 people who suffer from End Stage Renal Disease (ESRD). There are many factors that may affect one's ability to access treatment, but one that affects almost every in-center dialysis patient is transportation. This study examines how various spatial disparities, such as population density, Medicare coverage, Medicaid usage, poverty, commute times, and vehicle ownership, affect missed and shortened treatments due to transportation. To examine the relationship between spatial disparities and transportation-impacted treatment adherence, a random sample of 400 clinics were emailed to participate in the study, with 113 agreeing …

Epigenetic Mechanisms For Mediating The Transmission Of Prenatal Maternal Stress And Associated Neurodevelopmental Outcomes, Kaylee Vis

Senior Honors Theses

The hypothalamic-pituitary-adrenal (HPA) axis is the primary stress response system responsible for regulating cortisol release. During pregnancy, maternal stress can dysregulate the HPA axis, leading to elevated cortisol and corticosterone levels that impact fetal development. Excessive prenatal exposure to stress has been associated with alterations in fetal brain structure and function, increasing the risk for neurodevelopmental disorders such as autism spectrum disorder, attention-deficit/hyperactivity disorder, and anxiety. Emerging research supports the idea that these neurodevelopmental effects may be transmitted through epigenetic mechanisms. However, a gap remains in the literature regarding the specific mechanism of interaction between environmental stressors, heritable epigenetic information, …

Tetrahydrocannabinol: The Extraction And Analysis Of Thc Metabolites From Urine Via Sle And Lc-Ms/Ms, Kaycee A. Smith

Senior Honors Theses

Over the past few decades, widespread cannabis legalization has substantially increased forensic toxicology casework throughout the United States (National Institute of Justice, 2019). Washington state, an early adopter of recreational cannabis legalization, reflects this trend with toxicology laboratories reporting a 59% increase in annual case submissions since 2014 (Goldstein-Street, 2026). Current cannabinoid analysis methods involving liquid – liquid extraction (LLE) coupled with gas chromatography – mass spectrometry (GC-MS) are time consuming, labor-intensive, and require chemical derivatization and pH modification prior to analysis. To manage growing caseloads, an efficient method capable of consistently and reliably detecting THC is critical. The goal …

Navigating Cultural Biases And Self-Worth For Black Women Leaders In Higher Education, Robbin Mitchell

Interdisciplinary Leadership Dissertations

African American women leading at public universities share their thoughts and perspectives on days filled with more than just tasks; they bear silent struggles and the hidden expectation of being recognized for their work without being marginalized. While building inner strength, some find their voices amid doubt and pressure. Progress is made not through grand gestures but through small acts of care. Viewed through the lens of Black Feminist Thought (Collins, 2000), their lives reflect complex realities. Du Bois’s (1903) concept of split identities is relevant—not by choice but by context. Being Black and female reshapes their identities in leadership …

Menstrual Cycle Hormonal Fluctuations And Non-Contact Acl Rupture Risk In Female Athletes: A Literature Review, Alexa K. Larson

Honors Thesis

Anterior cruciate ligament (ACL) injuries are among the most common and debilitating injuries in athletic populations, with female athletes experiencing significantly higher rates of non-contact ACL rupture compared to males, often while participating in the same sports. Hormonal fluctuations associated with the menstrual cycle have been proposed as a potential intrinsic risk factor influencing injury susceptibility. The purpose of this literature review was to examine current research investigating how menstrual cycle-related hormonal fluctuations may influence the risk of non-contact ACL rupture in female athletes. A comprehensive search of PubMed, SPORTDiscus, and CINAHL databases identified fourteen peer-reviewed studies that met the …

Fallen Light, Joshua Do

Posters - 2026

Lucifer is often portrayed in popular media as purely evil; however, this interpretation overlooks the more complex idea of gradual moral corruption through deception and pride. The purpose of Fallen Light is to explore how doubt, pride, and subtle deception can lead even a highly exalted being away from God over time.. The game emphasizes the internal struggle between obedience and self-exaltation rather than immediate rebellion, and the problems with Being overly prideful.
