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.

The Experiences Of School Psychologists Serving Students With Traumatic Brain Injuries: A Phenomenology, E. Grace Ritchie

Electronic Theses and Dissertations

Traumatic Brain Injury (TBI) is a complex experience associated with a diverse constellation of symptoms and challenges. TBI scholars have extensively explored the varying needs of youth in the aftermath of a head injury. Likewise, recent literature details recommendations for school psychological services in support of these students. Such recommendations largely reflect insights drawn from broader TBI and disability research, integrated with the established scope of school psychologists’ practice (e.g., the National Association of School Psychologists Practice Model). Nevertheless, school psychologists’ perceptions of these students’ challenges have been inadequately examined. Such perspectives are likely valuable, given school psychologists’ unique training …

Trainee Countertransference And Competency In Bereavement Therapy: Strengths And Limitations Of The Wounded Healers, Meghan Paynter

Electronic Theses and Dissertations

Countertransference is a common experience in therapy, happening among clinicians of all stages of their career and the outcomes of this experience hinge largely on how countertransference is managed. Challenging topics, such as grief, only make countertransference harder to manage effectively and the management of this experience improves with practice and time—something trainees have not yet ascertained. Given the pervasiveness of grief as a human experience, also indiscriminate in nature, the experiences of trainees experiencing countertransference are important to understand, including what is experienced, how they experience it, and how it impacts their process and self-perception of confidence and competence …

Equilibration And Transport Of Binary Mixtures On Planar And Porous Nanomaterials, Andrew Torres

Electronic Theses and Dissertations

We present results of a Kinetic Monte Carlo investigation of the adsorption dynamics of binary gas mixtures on planar and porous sorbents, with a focus on identifying and characterizing kinetic processes involved in uptake evolution and how they influence equilibrium conditions. We also investigate varying thermodynamic simulation parameters such as interactions, alkane lengths, partial pressures and pore configurations to determine how they impact these kinetic processes as well as equilibrium properties. This study matters both for better understanding how kinetics and equilibrium are connected and for improving practical techniques in separation applications. For planar surfaces, weak species overshoot kinetic processes …

A Guidance Practice Model: Reframing Prevention, Identification, And Treatment Of Trauma-Impacted Students With Intellectual Disabilities, Mark H. Thomas

Electronic Theses and Dissertations

The experience and exposure of trauma among youth, especially continuous traumatic experiences, poses considerable risks of long-term effects. Moreover, untreated trauma and subsequently negative mental health outcomes, like anxiety and depressive disorders, can negatively impact the psychosocial and academic functioning of students. One population that is generally overlooked regarding mental health in schools are students with intellectual disabilities (ID). This is problematic as this population is at an increased risk of traumatic experiences, such as maltreatment and social exclusion.

Moreover, the comorbidity of trauma and internalizing disorders among students with ID can exacerbate already existing challenges and deficits with social …

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 …

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

Electronic Theses and Dissertations

Youth experiencing homelessness (YEH) face disproportionately high risk for HIV and sexually transmitted infections (STIs), yet rates of testing remain low. 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 …

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 …

Chronic Pain: An Exploration Of The Experience Of Chronic Pain, Andrea Alzalde

Electronic Theses and Dissertations

Chronic pain is a pervasive public health issue within Western society today and amongst humans worldwide. Although chronic pain is something that many people have or will experience sometime in their life, it is a complex experience that does not have a simple universal solution or immediate cure. The causes of pain can be a multitude of things and the treatments that work for some may not work for others. The current research seeks to explore the experience of chronic pain to help fill gaps in the wider research of pain. This study pursues answers to two research questions including; …

Parents reported significant improvements in their perceptions of their child’s social responsiveness, adaptive behavior, and executive functioning, as well as increased transition readiness ratings. Notably, parents evinced a significant decrease in acculturative stress (RASI) and depressive symptoms (PHQ-9), however, …

Self Spin-Orbit Torques, Ryan Greening

Electronic Theses and Dissertations

Spin–Orbit torques (SOTs) provide an energy-efficient pathway to control magnetization in nanoscale heterostructures. Recently, spin-orbit coupling within ferromagnets has been shown to generate self spin-orbit torques (SSOTs) on the magnetization itself. Previous work on self spin-orbit torques relies on thick ferromagnets with complicated film structures with chemical disorder or compositional gradients to generate inversion symmetry breaking. This dissertation advances experimental methodology and presents data on the quantification of self spin-orbit torques in magnetic thin films due to the spin-orbit coupling of standard 3d ferromagnets.

First, I develop an oblique-incidence magneto-optical Kerr effect (MOKE) technique that exploits a mirror-assisted double reflection …

Shifting From Damage Towards Desire At History Colorado: An Exploratory Case Study, Amanda Cali

Electronic Theses and Dissertations

This thesis explores the paradigm shift within the fields of anthropology and museum studies away from decolonization and towards indigenization through a case study of the changes in museological practices of the History Colorado Center in Denver, Colorado, and one of its community museums, the Ute Indian Museum in Montrose, Colorado. This thesis examines the changes in consultation and collaboration, the care and stewardship of collections, the implementation of the Protocols for Native American Archival Materials (PNAAM), and co-curation of exhibits. This thesis looks at the paradigm shift as a movement away from “damage-based research” within communities to “desire-centered research” …

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. …

Transgender Individuals’ Experiences Of Ruptures And Repairs In Group Psychotherapy, Gabrielle W. Kaufman

Electronic Theses and Dissertations

As the political climate across the United States worsens for transgender and gender diverse (TGD) individuals (Harmon, 2025), it has become increasingly important to attend to the mental health needs of this population (James et al., 2016). Group therapy is a widely used treatment modality that is often more accessible than individual therapy (Burlingame & Strauss, 2021) and provides unique interpersonal opportunities (Burlingame et al., 2016). While it is expected that TGD individuals face unique challenges in group therapy due to their gender identities (Chen et al., 2020), very little is actually known about the experiences of TGD individuals participating …

“My Body Was Never Mine”: An Arts-Based Phenomenological Analysis Of Queer And Trans Adolescent Involuntary Psychiatric Hospitalization Experiences, Megan Doyle

Electronic Theses and Dissertations

Involuntary psychiatric hospitalization has life-saving and crisis-stabilizing intentions for queer and trans adolescents experiencing mental health crises; however, there are significant concerns about the adverse effects of this practice. This study employed two interwoven qualitative methods, interpretative phenomenological analysis and arts-based research, to gain a deeper understanding of queer and trans individuals’ adolescent experiences of involuntary psychiatric hospitalization. The theory of abolition was applied to examine the carcerality and identity-based oppression embedded within this procedure. Participant narratives and artwork revealed how involuntary psychiatric hospitalization is non-affirming for queer and trans young people in crisis, and the impacts of experiencing coercion, …

Why Jerk Bosses Stress Us: Burnout As An Evolved Appeasement Strategy, Hector A. Garcia, Jarad Reiss, Ray Garza

All Faculty Scholarship (Archived)

Burnout is a pandemic and costly public health problem. Studies link leadership and peer behavior to burnout, but explanations are constrained to proximate mechanisms. Evolutionary models describe depression as an ancient appeasement response to avert dangerous physical conflict with higher-ranking group members and coalitions. In turn, psychometric research consistently finds high construct overlap between burnout and depression. This shared phenomenology suggests that burnout in response to workplace social stressors reflects appeasement. The purpose of the current study is to test the relationship between rank and competition related variables and burnout.

Temporary Intravascular Shunting Using A Carotid Shunt For Traumatic Femoral Artery And Vein Injury In A Hemodynamically Unstable Patient, Nicola Habash, Fari Fall, Jin Park, Babak Abai, Michael Nooromid

Department of Surgery Faculty Papers

Vascular trauma involving the peripheral arteries of the extremities can lead to limb loss and, in severe cases, death. The use of intravascular shunts can help to temporarily perfuse the limb, while allowing for resuscitation of a critically injured patient. Here we present a case of a concomitant complex injury of the common femoral artery and common femoral vein, and the complementary vascular strategies used to achieve limb salvage.

Code Before Clause: Building Canada’S Digital Defences Before Negotiating Trade, Barry Appleton

Articles & Chapters

Canada is about to give away the keys to its digital future — before it even decides what future it wants.

This paper argues that any exploratory discussions between Canada and the European Union on a digital trade agreement must be paused until Canada legislates a domestic digital sovereignty framework and builds the governance capacity to implement it.

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 …

Dendritic Cell Neurofibroma With Pseudorosettes: A Case Report, Nabiha T. Atiquzzaman, Fahad S. Siddiqui, Sadia Saeed, Jacqueline Russo, Patrick Dominguez

GME Publications

Dendritic cell neurofibroma with pseudorosettes (DCNP) is an exceedingly rare neurofibroma variant presenting as scattered, isolated, skin-colored papules or nodules primarily on the trunk. It consists of clusters of smaller type I cells with dark nuclei and inconspicuous cytoplasm, surrounded by much larger type II cells with abundant cytoplasm and vesicular nuclei containing pseudoinclusions, resulting in the formation of distinctive pseudorosettes. While unique, it can be misdiagnosed as other neural tumors due to its histologic and clinical similarities. This report presents a unique case of DCNP in a 34-year-old male with a longstanding, asymptomatic 1.3 cm pink nodule on his …
