Beyond The Individual: A Dyadic Mixed-Methods Study Of Work–Life Balance In Entrepreneurial Households., Juliana Binhote

Electronic Theses and Dissertations

Entrepreneurs operate at the intersection of work and family systems; yet, their experiences with work–life balance (WLB) remain underexplored—particularly in relational contexts. While existing research highlights the psychological demands of entrepreneurship, it often overlooks how family dynamics shape entrepreneurs’ experiences of balance, conflict, and boundary management. Guided by boundary theory, conservation of resources theory, and the goal attainment balance model, this dissertation investigates the question: How do entrepreneurs experience and make sense of their work-life balance? To answer this question, I designed a dyadic exploratory mixed-methods study. In Study 1, I conducted in-depth interviews with family business entrepreneurs and their …

An Exploration Of Lgbtq+ Runner Motivation And Constraints., Michael Clemons

Electronic Theses and Dissertations

Running offers extensive benefits beyond physical fitness, encompassing mental, emotional, and social advantages. However, LGBTQ+ individuals face unique challenges in participating in the running community, which remains predominantly White, cisgender, and heterosexual. With the LGBTQ+ population in the U.S. growing, there is a need to understand their motivations and barriers to participation in running events and training groups. This study explores these motivations using self-determination theory, comparing LGBTQ+ and non-LGBTQ+ runners to identify differences in driving factors such as social connectivity, self-esteem, and competition. Additionally, it examines barriers LGBTQ+ runners face, ranging from structural obstacles to intrapersonal challenges, and how …

Trauma Network Design Considering Patient Safety And Cost., Lin Lin

Electronic Theses and Dissertations

Trauma, as the leading cause of mortality and morbidity for those under the age of 45 in the US, incurs trillions in annual economic costs. The time-sensitive nature of trauma treatment necessitates an effective, coordinated regional trauma system to optimize patient safety. However, the financial burden associated with trauma care, especially due to low-insured population, presents a significant challenge to the financial health of trauma centers (TCs). To address critical challenges in this domain and provide much-needed insights to trauma decision-makers regarding their trauma system cost, network design, and subsidy policy, this dissertation proposes 3 contributions. First, we introduce an …

Analysis Of An Ethanol Sensitive Bmp-Nkx2.3-Fgf Signaling Pathway In Pouch Morphogenesis., Hieu Dai Le Vo

Electronic Theses and Dissertations

Craniofacial malformations lie at the heart of Fetal Alcohol Spectrum Disorders (FASD). While there is growing evidence for a genetic component to FASD, little is known of the cellular mechanisms underlying these ethanol-sensitive loci in facial development. Bone Morphogenetic Protein (Bmp) signaling pathway dependent pouch formation is a key mechanism in facial development. We have previously shown that multiple Bmp mutants are sensitized to ethanol-induced facial defects. However, ethanol does not directly impact Bmp signaling. This suggests that downstream effectors, like nkx2.3 and Fibroblast Growth Factor (Fgf) signaling, may mediate the impact of ethanol on Bmp mutants. Here, I …

College Leaders’ Perspectives Of Diversity At A Community College System In Texas: A Phenomenological Study Of Validation, Xandelyn Wright Washington

All Dissertations

The United States has undergone dramatic changes in student demographics over the last 40 years. Nowhere is this reflected more than in the field of education (Center for Public Education, 2012; Fabina et al., 2023). Disaggregation of student demographics is a useful and common method for measuring student outcomes, and in the United States, non-majority students consistently have lower student outcomes (Gay, 2013; Howard, 2010; Ocay et al., 2023).

Ma and Baum (2016) and McNair et al. (2015) stated that the role of community colleges is pivotal in postsecondary education. As such, college leaders and administrators have focused attention on …

Understanding The Potential Impact Of Ostracism On Lgbtq Health Disparities, Ellen D.B. Riggle

Political Science Faculty Publications

Research finds harmful impacts of ostracism on the health and well-being of the ostracized individual (as well as the ostracizer and members of the community). While often conceptualized as social (interpersonal), ostracism may originate at multiple levels of the socio-ecological system, including forms of political and institutional ostracism. The ostracism of LGBTQ people originates in cultural stigma and is reproduced and reinforced at all levels, from discriminatory laws and institutional policies (e.g., workplace, educational), to the actions of community or family members, to interactions with strangers. Ostracism, acute and chronic, creates increased risk for psychological and physical harm to LGBTQ …

Human Salivary Gland Stem/Progenitor Cells For Tissue Engineering, Sars-Cov-2 Susceptibility, And Neurointegration, Caitlynn Barrows

Dissertations and Theses (Open Access)

Salivary glands and the saliva they secrete are important for digestion, chewing, and maintaining oral health. Reduced saliva production leads to a decreased quality of life for patients experiencing hyposalivation as a result of disease or injury, thus a large effort has been dedicated to developing materials and medium to recapitulate the structure of the gland for regenerative medicine. In doing so, we have come closer to developing a more complex model to study disease. These models, however, do not yet fully recapitulate the gland. In this dissertation, we describe a new cell source that can be used to develop …

Integrating Bulk And Single-Cell Transcriptomics To Investigate Intratumor Heterogeneity, Shuai Guo

Dissertations and Theses (Open Access)

Cancers are heterogeneous mixtures of tumor and surrounding cells, where each component comprises multiple distinct sub-types and/or states. Understanding the cell-type-specific contributions is critical for advancing cancer biology, yet high-throughput expression profiles from tumor tissues only represent combined signals from all diverse cellular sources. Bulk deconvolution with single-cell/nucleus (sc/sn) RNA-seq data has emerged as a powerful approach to dissect both cellular composition and cell-type-specific expression patterns, yet the technological discrepancy across sequencing platforms limits accuracy.

To systematically evaluate the impact of platform discrepancies on bulk deconvolution, we first generated a benchmark dataset of 24 healthy retinas with paired bulk and …

Chronic Cluster Headache Is A Rare Disease: Implications For Diagnosis, Treatment And Public Health, Hsiangkuo Yuan, Jan Hoffmann, Elena Ruiz De La Torre, Michael J. Marmura, Mario F. P. Peres

Department of Jefferson Headache Center Papers and Presentations

Cluster headache (CH) is a rare and painful primary headache disorder characterized by severe unilateral pain and cranial autonomic symptoms. This perspective examines the epidemiological evidence supporting the classification of chronic cluster headache (CCH) as a rare disease, noting a prevalence of CH of approximately 124 per 100,000 individuals, with only 3.5-13.7% manifesting CCH. This prevalence meets criteria established by both the US Food and Drug Administration and European Medicines Agency for rare disease designation. The rarity of CCH creates substantial clinical and research challenges, including prolonged diagnostic delays, limited research funding and a dearth of approved treatments. The economic …

Saliva & Circadian Rhythm In Medical Profiling For Early Disease Prevention, Joseph Lewis

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Circadian rhythms affect almost every biological process from hormone secretion, gene expression, immune regulation, and metabolism. Studies show that disruption to these internal rhythms through irregular sleep, artificial sleep, and irregular sleep can significantly increase risk for chronic disease such as diabetes, cardiovascular disorders, neurodegeneration, and cancer. Saliva presents a viable alternative for capturing biomarkers found through blood or cerebrospinal fluid, offering substantial utility for diagnostic and chronobiological profiling. Saliva contains hormones such as cortisol and melatonin while containing inflammatory markers that fluctuate rhythmically throughout the day. Due to its ease of collection, saliva is well suited for longitudinal monitoring, …

Fluoride Toxicity And Benefit: An Integrated Review Of Mechanisms, Risks, And Public Health Impact, Sophia Chavarria

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Fluoride has long been praised for its role in preventing dental caries, primarily through its effects on enamel remineralization and antibacterial effects. However, growing evidence from molecular and cellular studies suggests that excessive fluoride exposure, especially during tooth development, can lead to dental fluorosis and systemic toxicity. This paper examines the biological mechanisms underlying fluoride-induced dental fluorosis, with a focus on stress responses in ameloblasts, oxidative damage, impaired autophagy, and disrupted protein processing. It integrates data from in vitro, in vivo, and human studies to evaluate the cellular thresholds at which fluoride shifts from therapeutic to toxic. Systemic risks, including …

One Step Closer To Greater Understanding! Does A Correlation Exist Between Fluid Intelligence And Player Rank In League Of Legends?, Evan Miller

Dissertations

Chess, one of the oldest modern games, has long been a model domain for expertise research. In comparison, research on video games has historically been influenced by moral panic. Cycles of moral panic tend to revolve around preconceived notions of threats, held at a societal level (typically by older generations). Politicians, quick to capitalize, then advocate for policy change based upon their constituents’ fears. Concurrent media reports draw further attention to the issue, amplifying the perception of harm. As the panic escalates, pressure is placed on scientific communities to perform confirmatory (not exploratory) research. This fundamentally biased approach to research …

More Arguments For The Weakness Of The Empirical Evidence Used To Support Spanking Bans: Rejoinder To Afifi Et Al. (2025) And Kraus De Camargo (2025), Marjorie Lindner Gunnoe, Robert E. Larzelere, Christopher J. Ferguson, Ronald B. Cox Jr.

University Faculty Publications and Creative Works

In this rejoinder we address 13 concerns elicited by our invited commentary “An update on the scientific evidence for and against the legal banning of disciplinary spanking.” In addition to defending assertions made in the initial commentary, we make several new substantive arguments. In response to dissenters’ equating of non-experimental evidence against spanking with nonexperimental evidence against smoking, we demonstrate that the two are very dissimilar. We question the purpose of spanking bans, providing stronger evidence that they do not seem to prevent child abuse. We review Canada’s association with the UN’s Convention on the Rights of the Child (CRC) …

Emotional Pathways To Trauma: Racialized Policing And Psychological Distress In Black Adolescent Males, Rochelle S. Parrish

All Theses

Introduction: Black American males, including adolescents, are disproportionately subjected to aggressive policing, often without criminal wrongdoing (Geller et al., 2014; Sewell et al., 2016). These encounters are frequently described as traumatic, marked by fear, loss, and emotional disruption (Smith Lee & Robinson, 2019). Whether direct or vicarious, such experiences can produce lasting psychological effects, particularly among Black boys who face compounded vulnerability from racialized surveillance and community-level trauma (DeVylder et al., 2018; Smith & Patton, 2016). Proactive policing tactics, such as investigatory stops and verbal aggression, have been linked to symptoms consistent with post-traumatic stress disorder (PTSD), including hypervigilance, avoidance, …
