The Resource Curse And U.S. Timber Harvest In Western Rural Economies, Lucas Paul Koch

Graduate Student Theses, Dissertations, & Professional Papers

There is limited understanding of the relationship between timber harvest and economic outcomes in the western United States. I use resource curse theory to examine the connection. The theory assumes a negative relationship between timber harvest and economic performance at the county level, and similar methods have been used to look at other natural resources and geographic areas. I use timber harvest intensity—the ratio of timber harvest volume to timberland acres—alongside several common economic controls including education, poverty, and competing industry activity to estimate wage and employment performance in a fixed-effects econometric model. Also estimated are least squares dummy variable …

“Emergency Relief As Routine”: The Evolution Of Fsa’S Livestock Forage Disaster Program In An Era Of Persistent Drought, Shae L. Olsen

Graduate Student Theses, Dissertations, & Professional Papers

This thesis examines the historical origins, current limitations, and future of the Farm Service Agency’s (FSA) Livestock Forage Disaster Program (LFP), the primary federal drought disaster relief program for ranchers in the United States. Drawing connections between the Dust Bowl-era Agricultural Adjustment Act (AAA) and LFP, I argue that the AAA, while innovative at the time, prioritized the maintenance of commodity markets over ecological resilience, disproportionately benefiting white, landowning producers. This trend is reflected in LFP today. Through a policy analysis and original qualitative research, including interviews with 23 FSA staff members in nine states, I examine how LFP operates …

Examining Coinfections With Human Cytomegalovirus, Christopher Samuel Peterson

Graduate Student Theses, Dissertations, & Professional Papers

Human cytomegalovirus (HCMV) is the largest of any human virus, both physically at up to 300 nm in diameter, and as a genome, with its 235 kbp DNA genome with at least 165 open reading frames. It is also the number 1 non-genetic cause of birth defects and has a global prevalence rate of just over 80%. Despite these characteristics, it is not as well known to the general public as some of the other human herpesviruses, such as herpes simplex or varicella-zoster virus. Like other herpesviruses, HCMV can establish latency, leading to a lifelong infection for its host with …

Equity And Social Vulnerability In Drought Planning And Response In The Northern Great Plains, Amishi Singh

Graduate Student Theses, Dissertations, & Professional Papers

Drought is a natural phenomenon that has long been a part of the climate regime in the Northern Great Plains. However, as climate change intensifies, drought across the region will worsen. This worsening drought will harm vulnerable communities more than their less vulnerable counterparts. Understanding how current policies either reinforce existing systems of marginalization or work to counter them is vital when determining what kind of policy will be needed in times of worsening drought. The first analysis sought to answer the following question: how are states incorporating key concepts of social vulnerability, procedural justice and climate change into their …

Community Resilience Factors For Gsm Individuals: Considering The Roles Of Transgender Identity And Age, Benny Ilac

Graduate Student Theses, Dissertations, & Professional Papers

Gender and sexual minority (GSM) individuals face a variety of health disparities, including increased rates of depression, anxiety, and substance use. One explanation for the presence of these health disparities is the minority stress model, which suggests that proximal (internal) and distal (external) experiences of minority stressors contribute to poorer health outcomes in GSM populations. An important yet understudied component of this model is resilience, which acts as buffer against the negative impacts of minority stressors. Focus on community resilience factors, as opposed to individual resilience factors, may be particularly important in GSM populations in reducing the onus placed on …

A Pilot Training Program For The Cultural Formulation Interview In School-Based Assessment, Jaida A. Lilly

Graduate Student Theses, Dissertations, & Professional Papers

School psychologists are responsible for promoting and maintaining an equitable, inclusive environment for all students to learn. For those who work in school settings, assessment of a student’s academic, mental health, and behavioral difficulties are often a significant component of school psychological practices. However, for various reasons, the assessment process can be flawed, and can unintentionally perpetuate systems of oppression in school-settings; this is especially true when working with children from culturally and linguistically diverse (CLD) backgrounds. Within culturally responsive assessment, conducting interviews is necessary for connecting with and effectively supporting the student and family. The Cultural Formulation Interview (CFI) …

The Effects Of Stigma On Mental Health Treatment Engagement, Kali Diane Strickland

Graduate Student Theses, Dissertations, & Professional Papers

Stigma is often cited as a significant barrier to mental health care (e.g., Andrade et al., 2014), but less is known about the impact of stigma on treatment engagement over time. The literature often calls for prospective studies (e.g., Clement et al., 2015). Additionally, little is known about label avoidance and its relationship to the other components of stigma, public and self-stigma. This study examined stigma’s association with mental health treatment engagement over time and the relationship between public stigma, self-stigma, and label avoidance. Specifically, the study assessed participants’ responses to stigma and related covariate measures. Approximately 5 weeks later, …

Methods To Improve Efficiency, Sensitivity, And Selectivity Of Sequence Similarity Search, Daniel Olson

Graduate Student Theses, Dissertations, & Professional Papers

The rapid growth of biological sequence data presents significant challenges for bioinformatic analysis. A cornerstone of this analysis, sequence similarity search, is hampered by three main obstacles: sensitivity in detecting distant evolutionary relationships, selectivity in distinguishing true homology from spurious similarity caused by features like tandem repeats, and scalability to handle massive databases. This dissertation introduces two novel computational tools, ULTRA and NEAR, that address these challenges to improve the efficiency, sensitivity, and selectivity of sequence similarity search. Part I of this dissertation addresses the problem of selectivity by focusing on tandem repeats, a common source of false-positive results in …

Advancing Wildfire Science Through The Application And Parametrization Of Process Based Fire Models, Anthony Albert Marcozzi

Graduate Student Theses, Dissertations, & Professional Papers

Computational models of wildfires are an important tool for fire managers and scientists. However, representing fuel inputs with sufficient detail for process-based fire models to accurately reflect observed fire phenomena while remaining computationally tractable is a major challenge. This dissertation advances wildland fire science by applying and parametrizing such models to investigate complex fire-fuel interactions across multiple scales.

A primary contribution addresses fine-scale fuel characterization through a novel voxel-based technique converting Terrestrial Laser Scan (TLS) point clouds into three-dimensional (3D) fuel representations. This method was evaluated by comparing simulated fire behavior in the Fire Dynamics Simulator (FDS), optimized using the …

America's Highest Stage: Utopians, Capitalists, And Trail Runners On Pikes Peak, Mitchell Morris

Graduate Student Theses, Dissertations, & Professional Papers

Since ancient times, Pikes Peak’s prominence on the land has endowed it with prominence in the minds of all who have lived around it. This ancient dynamic was reinforced in the nineteenth century by the famed expedition of Lieutenant Zebulon Pike in 1806 and the Pike’s Peak Gold Rush in 1858. Since then, the mountain has become a stage. Standing tall, visible from hundreds of miles around, and known from coast to coast, Pikes Peak is a platform that has attracted diverse historical actors to come and perform, elevate their endeavors to new heights, and demonstrate what they, and people …

Untangling Mining, Past And Present: An Analysis Of Key Informant Interviews On The Prospects Of Renewed Mining Activity Near Cañon City, Colorado, Lauren E. Nelson, Brian C. Chaffin

Graduate Student Theses, Dissertations, & Professional Papers

The Rocky Mountain West represents a distinct social-ecological region in a time of transition. As a subregion of the American West, it is defined by aridity, topography, and the physical, cultural, and economic impacts of mining across the landscape. Contemporarily, the region is increasingly shaped by an influx of tourism as well as seasonal and permanent residents who value the landscape for its recreational opportunities and aesthetic values. Most of the communities in the region owe their start to the mining booms of the 19th century, and many are still grappling with contamination left behind by mining. The transition between …

Identity Construction Of Post-2000s Class Monitors In The Public University Of China, Guoming Li

Graduate Student Theses, Dissertations, & Professional Papers

The identity construction experiences of a key group of student leaders in China’s public universities, class monitors born after the year 2000, were explored through a descriptive phenomenological approach guided by Giorgi’s (2019) framework. From the in-depth interviews with 14 participants, how these student leaders interpret and make meaning of their experiences within the unique context of China’s student cadre system was investigated. Three central dimensions of identity construction were showed: (1) alignment with servant leadership discourses that emphasize responsibility, care, and moral commitment to peers; (2) navigation of a complex followership process involving compliance and responsiveness to institutional supervisors; …

Mapping Mesic Resilience In Western Rangelands: Productivity Trends, Predictors, And Targeting Frameworks, Kristopher Robert Mueller

Graduate Student Theses, Dissertations, & Professional Papers

Mesic ecosystems in riparian areas and wetlands make up only 2% of western U.S. rangelands but support 80% of wildlife during dry periods, providing vital late-season forage and refuge when surrounding uplands dry out. Yet, mesic habitats are often overlooked in landscape-scale conservation planning. This thesis addresses two key gaps: understanding how mesic productivity responds to environmental change and developing frameworks to incorporate these habitats into current conservation strategies. Using 40 years of Landsat imagery (1984–2024), we examined long-term trends in late-season mesic vegetation productivity and its relationship with drought across the sagebrush biome. From 1984 to 2004, mesic productivity …

Challenged: A Practice-Based Analysis Of Simulating The Realities Of Teaching Through Play, Shanel Lara Locke

Graduate Student Theses, Dissertations, & Professional Papers

ChallengED is a classroom simulation game designed to explore the emotional and procedural realities of teaching through interactive play. Rather than attempting to manufacture empathy, the project focuses on conveying the unpredictability, humor, and fatigue that shape daily classroom life. Drawing from my own teaching experience, the game uses experiential realism and embodied interaction to communicate how educators navigate constant interruptions, shifting demands, and limited control. The development process also became a therapeutic practice, offering a way to reinterpret professional challenges through creative experimentation. Situated within practice-based research, ChallengED demonstrates how game design can function as both artistic inquiry and …

School Counselors in Training (SCITs) face distinctive challenges while developing their clinical skills and managing the complexities of school counseling. These challenges can lead to emotional strain and burnout, making it essential for SCITs to cultivate strong emotional regulation skills. Counseling and education researchers have discussed various strategies to assist counselors in enhancing emotional regulation skills. However, limited research has assessed the effectiveness of specific trainings on emotion regulation, especially for SCITs. This quantitative study investigates the effectiveness of an emotional regulation (ER) training program offered to SCITs during their field placements in schools. The central research question is whether …

Certificate Of Need Laws' Effect On Provisions Of Uncompensated Care, Connor Anthony Mostek

Graduate Student Theses, Dissertations, & Professional Papers

Certificate of need (CON) laws are regulations that require healthcare facilities to seek permission from a state government board to enter a market or expand/modify their established business. Proponents of CON laws claim that, among other things, CON laws protect hospitals and other healthcare providers from competition, allowing them to charge private or fully insured patients more in order to use the profits to “cross-subsidize” free care for low-income and uninsured patients. By employing an unbalanced panel dataset on hospital cost reports for the years 2012, 2014, 2016, and 2019, this study finds that there is no strong evidence that …

Refining Population-Level Measures Of Early Childhood Vaccination Coverage Using National Immunization Survey-Child Data, Alexandria Nicole Albers

Graduate Student Theses, Dissertations, & Professional Papers

Background: From 2011-2021, the U.S. Advisory Committee on Immunization Practices (ACIP) recommended 10 vaccine series by age 24 months, with guidelines for minimum vaccination age, maximum age for rotavirus vaccination, minimum dose intervals, and a catch-up schedule for delayed series initiation. National vaccination surveillance evaluates series completion based on whether children received the recommended number of doses, including a combined 7-vaccine metric (completed seven series collectively). However, this approach overlooks: 1) vaccinations given too early, too late, or too close together, 2) catch-up schedule vaccinations, and 3) completion of all 10 recommended vaccines.

Purpose: To refine national childhood vaccination coverage …

Examining Pathways For Front-Country Camping Access In The Rural American West: An Application Of Access Theory, Hayley Ann Johnson

Graduate Student Theses, Dissertations, & Professional Papers

Access to front-country camping on North American public lands has historically been preferential to those who are White, relatively wealthy, and highly educated. In theory, however, all activities on public lands are available to all people, and everyone has equal right to enjoy the benefits from recreational activities like camping in these spaces. Since the 1960s, research on access has focused on the barriers, or constraints, that influence overall participation in leisure activities; however, few studies have examined access specific to front-country camping.

As a complement and extension of traditional leisure constraints theory, this study presents a unique application of …

Binoculars To Bytes: Development And Field Validation Of An Ai-Driven System For Avian Monitoring, Christian J. Dupree

Graduate Student Theses, Dissertations, & Professional Papers

Autonomous camera-trap arrays coupled with artificial-intelligence (AI) vision can lift bird monitoring beyond the spatial, temporal, and labor limits of traditional field surveys. We present Binoculars to Bytes (B2B), an open-source pipeline that turns 180–360° time-lapse imagery into analysis-ready avian data. At Freezout Lake Wildlife Management Area (Montana, USA) the system ran four-hour morning deployments during spring and fall migrations (2023–2024). A YOLO-NAS detector, incrementally refined with a “Specialized Localized Iterative Model” workflow, quadrupled local accuracy and, after confidence-based species-binning, cut false-positive rates in half. Daily AI species lists were benchmarked against contemporaneous eBird citizen-science checklists and recovered ≥ …

Graduate Student Theses, Dissertations, & Professional Papers

How do adult children estranged from their parent(s) create meaning and make sense of their estrangement in Reddit posts on the subreddit r/EstrangedAdultChild? This study analyzed Reddit posts written by estranged adult children for a presumed audience of other estranged adult children. Using relational dialectics theory (RDT) as a lens for analysis, this research examined the competing discourses that influence the meaning-making and sense-making processes of estranged adult children in their posts when the intended audience is fellow estranged adult children. Seventy-four posts from r/EstrangedAdultChild, authored by adult children who self-identified as estranged from at least one parent, were collected …

Trace Level Benzoylecgonine Detections In Equine Plasma/Serum – A Proposed Interim Plasma Level Regulatory “Cut-Off“, Andreas F. Lehner, Kimberly Brewer, Levent Dirikolu, Abelardo Morales Briceñod, Robert Holland, George Maylin, Clara Fenger, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Cocaine is a widely used human recreational substance routinely transferring at pharmacologically irrelevant trace level amounts to non-user humans and horses. Horses and humans rapidly demethylate cocaine to benzoylecgonine which is excreted in urine at concentrations approaching two thousand times higher than the corresponding plasma cocaine concentrations. In human workplace drug testing, these usually pharmacologically irrelevant trace level urinary detections of benzoylecgonine are handled by application of a 100 ng/ml urinary “cut-off“, as presented by the Substance Abuse and Mental Health Services Administration (SAMHSA). In horse racing several American states have long used published urinary “cut-offs“ for benzoylecgonine of from …

Faculty, Staff and Student Publications

The COVID-19 pandemic revealed disparities in policy responses in Latin America. We examined the association between trust in the president and COVID-19 preventive behaviors in Brazil, Chile, Colombia, and Mexico. We used data from the Collaborative COVID-19 Response Survey by the McDonnell Academy at Washington University in St. Louis (United States), from September 2020 to March 2021. Nonprobabilistic sampling included adult citizens from the four countries. Multivariate negative binomial regression models were applied. The study included 8,125 participants, with Brazil showing the lowest adherence to preventive behaviors (65.5%). Increased adoption of preventive behaviors was linked with ages 18-26 (aIRR = …

Intercellular Mitochondrial Transfer Contributes To Microenvironmental Redirection Of Cancer Cell Fate, Julie Sofie Bjerring, Yara Khodour, Emilee Anne Peterson, Patrick Christian Sachs, Robert David Bruno

School of Medical Diagnostics & Translational Sciences Publications

The mammary microenvironment has been shown to suppress tumor progression by redirecting cancer cells to adopt a normal mammary epithelial progenitor fate in vivo. However, the mechanism(s) by which this alteration occurs has yet to be defined. Here, we test the hypothesis that mitochondrial transfer from normal mammary epithelial cells to breast cancer cells plays a role in this redirection process. We evaluate mitochondrial transfer in 2D and 3D organoids using our unique 3D bioprinting system to produce chimeric organoids containing normal and cancer cells. We demonstrate that breast cancer tumoroid growth is hindered following interaction with mammary epithelial cells …
