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 …

Developing Deep Learning Methods For Cognitive Impairment Detection Based On Non-Invasive Data, Muath Alsuhaibani

Electronic Theses and Dissertations

Cognitive impairment detection is on the rise to help reduce the burden of healthcare costs on institutions and individuals. Mild Cognitive Impairment (MCI) is an early stage of cognitive decline progressing to Alzheimer’s disease (AD) or AD-related Dementia (ADRD). Detecting the early stages of AD/ADRD is crucial for early interventions among older adults to mitigate cognitive decline over time. However, the current diagnostic methods are often costly and/or invasive, such as MRI and PET scans. Thus, the search for non-invasive and cost-effective screening tools for the early detection of cognitive impairment using speech, language, visual, and motor data is growing. …

Surgeon Ergonomics While Performing Total Knee Arthroplasty, Cameron Dahman

Electronic Theses and Dissertations

One of the most prevalent hazards to orthopedic surgeons are musculoskeletal disorders with 97% of arthroplasty surgeons reporting procedural-related musculoskeletal pain and 66% of orthopedic surgeons reporting procedural-related musculoskeletal injury [1], [2], [3]. With the annual number of total knee arthroplasties (TKA) on the rise, orthopedic surgeons are taking on larger annual caseloads and retiring later in life [4], [5]. The goal of this study was to quantify postural demand for 11 discrete surgical steps of TKA to identify ergonomically unfavorable positions surgeons experience while operating. Four orthopedic surgeons performed TKA while their motions were recorded using marker-based motion capture. …

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 …

The purpose of this narrative inquiry study was to better understand race in contexts both domestically and abroad through the perspectives and experiences of white women who studied abroad outside of Europe and the Anglosphere. The investigation explored on how these experiences shaped white women’s understanding of racial identity upon returning to their home institutions. The research question which was addressed was: How do white women experience study abroad programming? Research highlights a critical gap in existing literature on this topic. While white women are centered in the study, it is contextualized considering how People of Color experience the world. …

Exploring The Meaning Of Moshing: An Ethnographic Study Of The Relationship Between Hardcore/Punk Culture And Catharsis, Clayton Kempf

Electronic Theses and Dissertations

This research looks at “moshing,” an aggressive style of dancing that occurs primarily at hardcore/punk concerts. Moshing involves people at a concert throwing their bodies, swinging their limbs, running into people, and hitting one another. I aim to explore how mosh pits and hardcore/punk culture provide participants with an emotional release through catharsis. Catharsis looks at releasing emotion to help alleviate pent-up stress physically and emotionally. A cathartic release can temporarily offer peace of mind, clarity, and joy that overrides the feelings of negative emotions and stress. I will examine the process people go through to reach this cathartic release …

Hiv And Sti Testing Service Utilization Among Youth Experiencing Homelessness: A Multi-Method Inquiry, Alexander A. Ochs

This dissertation examines the individual and social network level factors that influence HIV/STI testing behaviors among YEH. Guided by insights from multiple theoretical frameworks, this three-paper dissertation integrates quantitative and qualitative approaches to better understand how personal relationships and social context shape HIV/STI testing decisions in this population.

Paper 1 presents a secondary data analysis of the Homeless Youth Risk and Resilience Survey (HYRRS), which includes 1,426 YEH across seven U.S. cities. Logistic regression models identified geographic variation in …

Comparing Ordinary Least Squares And Quantile Regression: A Causal-Comparative Approach To Modeling Conditional Relationships, Samuel Nnorom

Electronic Theses and Dissertations

Ordinary Least Squares (OLS) regression has traditionally been the preferred quantitative method for estimating linear relationships. However, it assumes that the effect of a predictor variable remains constant across the entire outcome distribution, which can miss important insights when data are heterogeneous. Quantile Regression (QR), on the other hand, offers a more detailed analysis by focusing on the full response variable distribution, thereby revealing different relationship patterns at various quantiles within the outcome. This study compares how OLS and QR perform in modeling conditional relationships within a causal-comparative framework based on ex post facto research. Using the mortality data from …

Better Serving Those Who Serve: Supporting Psychological Wellness Of Lgb Military Personnel In The Post “Don’T Ask Don’T Tell” Era, Anne Neuweiler

Electronic Theses and Dissertations

Few studies have been able to explore lesbian, gay, and bisexual military personnel’s experiences in military mental healthcare settings. This study examined the experience of LGB servicemembers in military counseling environments, as well as how to support these servicemembers in military mental health and military communities. Six participants volunteered for the study and six semi-structured interviews were completed with LGB servicemembers who had contact with mental health. Three research questions guided the present study and a transcendental phenomenological frame was used to analyze the data and themes emerged. Research question one yielded three themes: 1) “I'm Definitely not Gay”: The …

The Covid-19 Pandemic As An Environmental Jolt And Its Impact On Firms And Essential Workers, Kimberly Kay Hyett Nehls

Electronic Theses and Dissertations

Environmental jolts are sudden, large-scale disruptions that challenge organizational and societal stability and demand new ways of understanding adaptation across individuals and firms. This two-paper dissertation explores the human and organizational dimensions of such jolts through the empirical context of the COVID-19 pandemic. Paper 1 examines how global tourism firms navigated the crisis, introducing the constructs of global stakeholder interconnectedness and stakeholder prioritization fluidity to refine stakeholder theory. The findings show how international exposure shaped communication strategies under duress. Paper 2 turns to the lived experiences of low-wage essential workers, extending sensemaking theory through the concept of constrained sensemaking, highlighting …

Prolonged Exposure To Food Odors Suppresses Feeding Via An Olfactory Bulb-To-Hypothalamus Circuit, Yao Liu, Hailan Liu, Huey-Xian Kelly Wong, Niccole Auld, Kristine M Conde, Yongxiang Li, Meng Yu, Yue Deng, Qingzhuo Liu, Xing Fang, Mengjie Wang, Yuhan Shi, Olivia Z Ginnard, Yuxue Yang, Longlong Tu, Hesong Liu, Jonathan C Bean, Junying Han, Megan E Burt, Sanika V Jossy, Yongjie Yang, Chunmei Wang, Qingchun Tong, Benjamin R Arenkiel, Hongjie Li, Yong Xu, Yang He

The Brown Foundation: Institute of Molecular Medicine

Olfactory perception of food odors is a key determinant of eating behavior, including triggering appetite, facilitating food seeking and influencing food choice. While transient food-related olfactory cues stimulate appetite and provoke cravings in states of hunger, emerging evidence implies that prolonged and sustained exposure to food-derived odor (FO) suppresses feeding. However, the mechanisms by which olfaction induces hypophagia remain elusive. In this study, we show that prolonged FO exposure significantly suppresses food intake in male mice. We identified a subset of neurons in the ventral subiculum (vSub) that are specifically activated by FO. We further discovered that these FO-activated neurons …

While the cause of preterm birth (PTB) (i.e., delivery before 37 weeks of gestation) is likely multifactorial, ambient exposure to environmental chemicals has been postulated to play a role in its etiology. Our prior studies of exposure to polycyclic aromatic hydrocarbons (PAHs) in pregnancy have shown an increased level of placental PAH-induced bulky DNA adducts with increasing levels of PAH exposures. In this investigation, we hypothesized that higher levels of placental PAHs would be associated with an increased risk of PTB. Using gas chromatography and mass spectrometry (GC-MS/MS), we measured levels of benzo(a)pyrene (BaP), benzo(b)fluoranthene (BbF) and dibenz(a,h)anthracene (DBA) from …

Targeting Sting To Disrupt Macrophage-Mediated Adhesion In Encapsulating Peritoneal Sclerosis, Huolin Ye, Qiang Huang, Hu Zhou, Canming Li, Mei Liao, Yujia You, Hongli Shang, Pan Zhou, Dongxuan Wu, Janusz Witowski, Zhaoyong Hu, Hui Peng

Faculty, Staff and Students Publications

Encapsulating peritoneal sclerosis (EPS) is a life-threatening fibrotic condition characterized by severe abdominal adhesions, chronic inflammation, and significant morbidity. The lack of effective treatments for EPS stems from a limited understanding of its underlying mechanisms. In this study, we developed a modified mouse model of PD-induced EPS and investigated the role of the STING signaling pathway in disease progression. Our findings reveal that STING activation in peritoneal mesothelial cells significantly increases the secretion of the macrophage chemokine CCL2, leading to enhanced macrophage infiltration and the formation of pathological adhesions. Notably, pharmacological inhibition of STING using the inhibitor H151 effectively reduced …

The Multicultural Orientation Framework In Couple Therapy, Jasmine R. Davis

Electronic Theses and Dissertations

Couples’ cultural values and beliefs are important to their relational connection. Cultural values and beliefs can be sources of strength in relationships, but they can also lead to impasses. As such, clinicians and researchers could benefit from a cultural framework to inform conceptualization and treatment when working with couples. The Multicultural Orientation (MCO) framework has three pillars: cultural humility, cultural comfort, and cultural opportunities. The MCO framework is empirically supported for use in individual and group psychotherapy but has not been applied to couple therapy. This dissertation includes two parts. First, we outline a conceptual framework for the application of …

Alameda Song Sparrow Habitat Use Of Salt Pond Restoration Sites In South San Francisco Bay, Bradley A. Speno

Master's Theses

Restoration is acknowledged worldwide as a conservation need to return ecosystem functions. However, projects require monitoring to track system changes and assess restoration progress. In the San Francisco Bay, several large restoration projects are implementing plans to return salt-producing ponds to the historical ecosystem, tidal salt marsh. The Alameda song sparrow (Melospiza melodia pusillula), a California species of special concern, has been documented to use restored and historic marshes, but their use of restored salt ponds is not fully understood. The birds’ use of restored marshes may be a useful measure of restoration progress. This research investigated the relationships comparing …

Examining Barriers To Crisis Service Use Among Black Young Adults, Emily K. Burns

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Black communities face an increased burden of mental illness (Gordon, 2020). This can be linked to factors such as experiences of racism, higher rates of unemployment, financial and food insecurity, and disparities in health care (Gordon, 2020). Despite this, Black communities have historically experienced relatively low rates of suicide (Gordon, 2020). This has been anecdotally attributed to protective cultural values and beliefs about suicide. However, there has been a recent shift in this trend, particularly for Black youth and young adults.

A Systematic Review Of Technology-Infused Physical Activity Interventions In K-12 School Settings: Effectiveness, Roles, And Implementation Strategies, Taemin Ha, Jongho Moon, Hyeonho Yu, Xiaoping Fan, Lisa Paulson

Department of Kinesiology Scholarship and Creative Works

Background

Rapid technological advancements have rendered many prior reviews of technology-integrated physical activity (PA) interventions in K–12 schools obsolete. A comprehensive analysis examining both the effects of these interventions and the specific roles that technology plays has been notably lacking. This review aimed to systematically examine the effects of technology-infused PA interventions and identify the specific types, roles, and contextual applications of technology within K–12 schools.

Methods

This systematic review adhered to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A thorough search across seven electronic databases (CINAHL, ERIC/EBSCOhost, PsycINFO, PubMed/MEDLINE, Scopus, SPORTDiscus, and Web of Science) …

Characterization Of L-Band Resonators And Relaxation Times Of Soₓ- Radicals At X-Band, Georgina Naa Odey Amassah

Electronic Theses and Dissertations

Electron Paramagnetic Resonance (EPR) analysis requires resonators optimized for specific experimental challenges. Volume resonators enclose samples, while surface coil resonators allow imaging of larger subjects. For in vivo studies, L-band frequencies are commonly used because they offer a good balance between signal-to-noise ratio (S/N) and the ability to penetrate tissue. Rapid Scan (RS) EPR at L-band frequencies was chosen for my studies of resonators because of this balance but presents a challenge for sensitivity.

The spatial position dependence of signal intensity was evaluated for selected paramagnetic samples using 10 mm and 30 mm surface coils. The 10 mm coil, with …

A Phenomenological Study Of Caregivers For Sexual Minority Hospice Patients, Catherine H. Bianchi

Electronic Theses and Dissertations

Lesbian, gay, and bisexual (LGB) individuals face disproportionate barriers in healthcare across the lifespan that persist and often intensify at the end of life. Despite hospice’s mission to provide comfort, dignity, and patient-centered support, it remains unclear whether these services equitably meet the needs of sexual minority patients. Seeking hospice care presents a unique conundrum for many LGB individuals: it necessitates inviting representatives of a historically exclusionary healthcare system into the privacy of their homes - spaces that often serve as sanctuaries of identity, safety, and autonomy. The already vulnerable experience of seeking care in one’s final days can be …
