A Backtracking Algorithm For Determining The Existence Of Regular Graphs Of Specified Girth And Excess, Stetson Ray Bosecker

Doctoral Dissertations

The study of cages focuses on finding (k, g)-graphs of minimal order. This dissertation generalizes the problem of finding cages to the determination of graphs with specified excess, thereby broadening the significance of the results. The (k, g, ε)-graph problem seeks to determine the existence or nonexistence of k-regular graphs with girth g and excess ε = n(G)−M(k, g) (where M(k, g) represents the Moore bound for cage graphs). Motivated by heuristic methods used to determine properties within the study of cages, we present a backtracking algorithm capable of constructing (k, g, ε)-graphs or determining their nonexistence. Chapter 2 provides …

Privacy-Preserving Structure Learning For Geospatial Data Using Information-Theoretic Dependency Measures, Ahmed Mudhish

Doctoral Dissertations

This dissertation proposes a privacy-preserving framework for structure learning in Bayesian networks (BNs) that addresses the challenges of distributed geospatial data face. Geospatial datasets often exhibit region-specific patterns such as sparsity and nonlinear dependencies. These patterns undermine the effectiveness of traditional machine learning models. Additionally, learned BN structures may reveal sensitive relationships in the generated graph by BNs. These relationships pose a significant privacy risk if reverse-engineered. To address these issues, three novel algorithms are introduced. First, the Selective Naïve Bayes with HSIC (SNB-HSIC) algorithm applies a kernel-based dependency measure to filter redundant and irrelevant features in sparse datasets, improving …

Personality, Self-Compassion, And Alcohol Use In College Students, Kristen Kay Ridgdell

Doctoral Dissertations

Substance use has been occurring throughout history, and most individuals have been impacted by substance use in one way or another (Durrant & Thakker, 2003). The individual using substances is not the only one who faces the consequences of their usage. Their families and communities also pay a price (Lander et al., 2013; McLellan, 2017). College students are in a unique role in their lives where they are fighting for autonomy, trying to fit in with their peers, and facing new stressors they have never experienced before. Previous research has demonstrated that certain personality traits, including conscientiousness and agreeableness, are …

Lactation Management Training In Graduate Nutrition And Dietetics Programs: A Preliminary Report, Laura Ashton Gillin

Master's Theses

The American Academy of Pediatrics recommends exclusive breastfeeding (BF) for the first six months and continued breastfeeding for at least two years with complementary food. Despite this recommendation, only 24.9% of infants in the United States are exclusively breastfed at six months (Breastfeeding Report Card 2022). Breastfeeding support and lactation management are critical to promoting a successful breastfeeding experience. Specifically, qualified support from a Registered Dietitian Nutritionist (RDN) is recommended, yet graduate students in Nutrition and Dietetics do not receive adequate training regarding breastfeeding intervention. This study aimed to evaluate graduate Nutrition and Dietetic programs to determine the amount of …

Sleep, Emotion Regulation, And Relationship Satisfaction: A Moderation Analysis, Lakyn Boone

Doctoral Dissertations

Sleep plays a pivotal role in overall health and well-being, influencing mental health, cognitive abilities, memory, emotional balance, and physical well-being (Luyster et al., 2012; Mukherjee et al., 2015). Emotions constitute a natural and indispensable element of human existence but necessitate proper regulation, as any disruption in emotion control has been associated with various mental health disorders (Gross & Jazaieri, 2014; Kring & Gordon, 1998; Phelps, 2006). Furthermore, human connections and relationships are fundamental aspects of the human experience, contributing to emotional support, personal growth, a sense of belonging, and even influencing one's physical health outcomes (Baumeister & Leary, 1995; …

Federated Boolean Matrix Factorization Using Integer Programming, Quynh Anh Nguyen, Ngoc Nguyen, Nhat Phan

Research from the Berry Summer Thesis Institute, 2025

Identifying the underlying structural patterns in data and extracting meaningful insights is a key challenge in data analysis. One effective approach to this problem is matrix factorization (MF), which approximates large matrices with lower-dimensional representations, making it effective for uncovering hidden patterns. MF techniques are widely applicable across various domains, such as recommender systems, cancer genomics, system identification, clustering, and image processing. Despite their effectiveness, existing MF methods often struggle with computational constraints and convergence challenges when tackling large-scale, nonsmooth, and nonconvex optimization problems, which are common in real-world applications.

This project aims to explore both the theoretical understanding and …

Assessing The Role Of Employees' Esg Perception On Turnover Intention: A Moderation Analysis, Michelle Leong

Doctoral Dissertations

This dissertation examines the relationship between employees’ perceptions of their organization’s ESG performance and turnover intentions by drawing upon Social Identity Theory (SIT). SIT suggests that individuals internalize organizational values and beliefs through organizational socialization, which strengthens their identification with the organizations, leading to support for organizations that embody those values. This study also investigated whether ESG awareness is a better predictor than ESG perception. The research employed a cross-sectional survey design to examine whether age and political affiliation moderate the relationship between ESG perception and turnover intention. The findings suggest that employees’ perceptions of their organization’s ESG performance are …

Hardiness, Coping, And Well-Being In Trauma-Exposed College Student-Athletes, Kiara Scott

Doctoral Dissertations

College student-athletes (CS-As) face many stressors, such as adjusting to a university setting, academic pressures, and the demands of an elite athlete (e.g., battling at a high level during training and competition and managing mental struggles in their sport) (Barbayannis et al., 2022; Barnard, 2016). Some individuals are exposed to events that may be classified as traumatic, such as physical and sexual assault, natural disasters, and other related forms of human suffering (American Psychiatric Association, 2013). Around 50%-80% of college students have been exposed to at least one traumatic event throughout their lifetime (Frazier et al., 2009; Read et al., …

An Envisioned And Efficient Design Of Next Generation Decentralized Iot Bot Detection Model, Ahmed Abdullah Almalki

Doctoral Dissertations

The Industrial Internet of Things (IIoT) and Internet of Medical Things (IoMT) are revolutionizing critical infrastructures, but their expansion has also introduced severe cybersecurity vulnerabilities. Traditional IoT Bot Detection Systems (IBDS) struggle to scale in environments characterized by high-dimensional, large-scale, and redundant network traffic. These challenges hinder the development of reliable cloud-based intrusion detection systems. The limitations of static and rulebased methods in detecting evolving IoT botnet attacks—such as those launched by Mirai and Gafgyt—underscore the need for intelligent, adaptive approaches. To address this, the present study proposes a machine learning and deep learning-driven IoT Botnet Detection Model, validated through …

Vitamin B12 Deficiency: Confidence, Perspectives, And Practices Among Registered Dietitian Nutritionists, Avery Miller Adams

Master's Theses

Vitamin B12 deficiency is common in the United States, occurring in 20% of adults aged 60 and above (Andres et al., 2004). Veterans are susceptible to B12 deficiency due to tobacco product usage, alcohol consumption, and poor diet quality. Megaloblastic anemia is the second most prevalent vitamin deficiency disorder recorded in military personnel from 1997 to 2015 (Knapik et al., 2021). This exploratory, analytic research aims to assess registered dietitian RDN nutritionists’ (RDN) knowledge, perceptions, and intentions regarding treating vitamin B12 deficiency in a clinical setting. Due to population prevalence differences, responses from VA and non-VA practicing registered dietitian-nutritionists (RDNs) …

Is There An Association Between Food Literacy And Diet Quality In Young Adult College Men?, Morgan Claire Mayeux

Master's Theses

Food literacy skills can improve dietary intake in young adults as it provides them with the tools they need to make healthier food-related decisions. The benefits of improving food literacy includes the reduction in the risk of prevalent, preventable dietrelated diseases such as obesity, T2DM, heart disease, and other chronic diseases that plague the Unites States today. Previous literature reports primarily on college female samples. Because a large proportion of the samples in the available studies are female, the current literature may not reflect young adult men’s food literacy and its comparison to their overall diet quality. The purpose of …

Disproportionate Insider Control And The Cost Of Equity Capital: Evidence From U.S. Dual-Class Firms, Barry Hettler, Arno Forst, Lindsay Baran

School of Accountancy Faculty Publications

We investigate the cost of equity capital for U.S. dual-class firms. While prior literature finds a positive association between excess insider control and the cost of capital in international contexts, these results are primarily concentrated in countries with relatively weak investor protection and legal enforcement. It is therefore an open question whether these findings hold for the U.S. capital market. Additionally, we investigate a possible moderating role of the firm’s information environment on the association between disproportionate insider control and the cost of capital. We find the cost of equity capital for U.S. dual-class firms is, on average, approximately forty …

Food Insecurity, Diet And Health Outcomes In Pediatric Inflammatory Bowel Disease: A Pilot Study, Nicole Zeky, Alysse Baudier, Colleen Leblanc, Elizabeth Mcdonough, Sarah A. Dumas, Dedrick Moulton

School of Medicine Faculty Publications

Background/Objectives: Food insecurity (FI) is a well-defined factor in pediatric health outcomes and has been associated with lower diet quality. While poor diet quality has been linked to the rising prevalence of inflammatory bowel disease (IBD), little is known about the impact of FI on pediatric IBD. This pilot study explores the feasibility and potential impact of FI on dietary intake and clinical outcomes in children with newly diagnosed IBD. Methods: This pilot study included newly diagnosed IBD patients aged 5 to 18. FI screening was completed using the USDA 6-item and AAP 2-item screeners at diagnosis and 6 months. …

Socio-Cultural Correlates Of Breastfeeding Behavior Among Latina Mothers And Its Implications For Child Health, Liliana Davalos, Brisa Rodriguez Alcantar, Marissa Martinez, Christopher Johansen

Social and Behavioral Health Faculty Research

Background: Latina mothers in the United States report lower rates of breastfeeding initiation and exclusivity than their non-Hispanic counterparts. Lower rates of breastfeeding in infancy may lead to a higher rate of excess weight in childhood and adverse health conditions. Breastfeeding disparities in Latina women have been previously correlated with socio-cultural factors such as acculturation, education, income, nativity, and marital status. This study examines whether socio-cultural factors are associated with breastfeeding behaviors in Latina mothers in Nevada. Methods: Participants were Latina mothers [n = 214] over 18 years of age, with a child 2–5 years old. A logistic regression was …

The Effect Of Education Policy On Crime: An Intergenerational Perspective, Ulrika Ahrsjö, Costas Meghir, Mårten Palme, Marieke Schnabel

Cowles Foundation Discussion Papers

We examine the intergenerational effect of education policy on crime. Using administrative data that links outcomes across generations with crime records, we show that the Swedish comprehensive school reform, gradually implemented between 1949 and 1962, reduced conviction rates for both the generation directly affected by the reform and their sons. The reduction in conviction rates occurred in several types of crime. Mediation analysis suggests that key channels include increased parental educational attainment and household income, as well as reduced criminal behavior among fathers.

Influence Of Obesity On Knee Joint Mechanics: A Subject-Specific Musculoskeletal Modeling Approach, Ryan C. Knowles

Electronic Theses and Dissertations

Obesity has been consistently linked to knee osteoarthritis (KOA), a debilitating joint disease. While prior work has shown that obese individuals often walk with altered biomechanics compared to normal-weight (NW) individuals, which may accelerate KOA progression, less is known about how these mechanics affect load distribution between the medial and lateral tibiofemoral (TF) compartments, particularly during higher-demand activities. This study developed subject-specific musculoskeletal models of five obese and five NW individuals, incorporating CT-based bone measurements and individualized joint contact points. Simulations were driven by six degree-of-freedom (6DOF) kinematics obtained from high-speed stereo radiography (HSSR) to predict TF loading and associated …

Exhibiting Rural Consciousness: A Study Of State And Local Level Governance In Rural Higher Education, Steven J. Skadron

Electronic Theses and Dissertations

Evolving economies in Craig and Salida, CO, spurred community interest in joining Colorado Mountain College’s taxing district and bringing the college to their communities. When they sought to join, Craig had a local college embedded in its community that was governed by a state-level board; in contrast, Salida had no local college of its own. The two communities’ pursuit of a locally governed college raised a question about governing boards and whether one type of governing board might serve rural communities better. Using a framework of rural consciousness, this nonexperimental, cross-sectional, quantitative study employed data gathered from a survey instrument …

Recruiting, Retaining, And Culturally Sustaining Latine Teachers In A School District With A High Population Of Latine Students, Lisa Garcia Simms

Electronic Theses and Dissertations

Latine students make up 52% of the Denver Public Schools (DPS) population, yet only 23% of its teaching force is Latine. This imbalance has real implications for student experience and opportunity. In 2024, DPS commissioned the La Raza Report, which detailed challenges faced by Latine students and educators and called for systemic improvements. The findings highlighted a clear need to strengthen recruitment, retention, and culturally sustaining support for Latine educators.

This improvement science project investigated how DPS might improve the experiences of Latine teachers—engaging educators across career stages, with a particular focus on supporting early-career Latine teachers —through identity-affirming mentorship …
