Evaluating (Bio)Degradation Of Carbon Tetrachloride In Fe(Iii)-Reducing Environments, Adam Rogers

All Theses

Understanding degradation of carbon tetrachloride in-situ is vital for many remediation projects across the world, yet conclusive evidence of its feasibility is lacking in previous studies.

The main objective of this research is to assess the potential for carbon tetrachloride attenuation by biological, abiotic, and combined processes in a Fe(III)-reducing aquifer. In doing so, it assesses the effect of pH and stoichiometric ratio on abiotic degradation of carbon tetrachloride using various reducing agents, evaluates iron-mediated versus direct biotic degradation of carbon tetrachloride using pure cultures under resting and growth conditions, and characterizes the effects of culture strain, electron acceptors and …

Based on a review of methods and technologies for counting nonmotorized users; analysis of counting programs established by local, state, and regional transportation agencies; and a …

The Effects Of National Elite Signaling On Ranked Choice Voting In Utah, Mathew Woodman

All Graduate Reports and Creative Projects, Fall 2023 to Present

Ranked-Choice Voting (RCV) is a voting method used in few cities in the United States. There has recently been an increase in interest in adoption of the voting method in other cities using pilot programs, much like the one introduced in Utah. Ranked-Choice Voting has become a topic of contention with strong disapproval coming from opponents of the voting system. The questions are why there is disdain for Ranked-Choice Voting, and why such disdain seems to exist more heavily in Republican camps. Public opinion polling from “likely and confirmed Utah voters” in Salt Lake, Utah, and Grand Counties, conducted by …

Redressing The Harm Of Accelerated Approval, Laura Karas

Articles

The accelerated approval pathway of the United States Food and Drug Administration (FDA) enables drugs to come to market more quickly than would be possible under a traditional FDA approval pathway. Accelerated approval is based upon the agency's determination that changes in a surrogate or intermediate clinical endpoint are "reasonably likely" to predict a clinical benefit meaningful for patients. In essence, the pathway affords sick patients earlier access to potentially beneficial drugs while trials to confirm clinical benefit continue. Accelerated approval has been likened to a social compromise in which promising drugs enter the market sooner in exchange for a …

Ai Governance In China: A Tale Of Three Digital Empires, Charles C. Wang, Siyi Lin, Xia Wu, Yiman Li

UC Law SF International Law Review

Since 2021, China has strategically expedited artificial intelligence (AI) legislation and refined algorithmic governance to compete with the US and the EU. The rapid growth of algorithm filing cases is a direct result of the “Made in China 2025” Initiative which prioritizes AI development driven by domestic leading tech companies like DeepSeek. As world-class digital powers, China, the US, and the EU diverge in their categorization of AI risks and adoption of regulatory measures. China’s centralized single-agency regulatory infrastructure differs from the multi-agency and decentralized governance models in the US and the EU, respectively. China does not impose the same …

Project Choices: An Experimental Serious Video Game For Performance-Based Risk Assessment, Rachel Bomysoad

Theses, Dissertations and Culminating Projects

Risk assessment for future criminal conduct currently relies on evaluator ratings or self-report measures, with imperfect predictive utility. A new serious (clinical) video game, Project Choices, was developed for assessment and treatment purposes with persons involved with the criminal legal system. Project Choices offers performance-based measurement of individuals’ responses to realistic scenarios relevant to overall criminogenic risk and individual risk factors. The current study aimed to pilot test the newest version of Project Choices (Version 2) using a sample of university students (N = 100), examining gameplay performance metrics (number of risky decisions overall and within individual risk domains) for …

Electrophysiological Markers Of Emotion Dysregulation In Autistic Youth, Rachel G. Mcdonald

Theses, Dissertations and Culminating Projects

Emotion dysregulation (ED) is a transdiagnostic mechanism that is conceptualized as difficultly regulating emotions and deploying appropriate regulation strategies in response to environmental stimuli. Meta-analyses suggest that autistic people, across the lifespan, experience more severe ED as compared to both neurotypical people and those with mental health conditions. Despite elevated risk and evidence linking ED to disruptions in neural mechanisms, no studies to date have examined neural markers of ED in autistic populations. The current project uses multi-method and multi-informant measurement to examine similarities and differences in neural mechanisms of ED in autistic and non-autistic populations. Forty-four youth aged 11—17 …

Seeing Students For Part Of Who They Are: High School Counselors' Experiences Broaching, Jessica M. Miserentino

Theses, Dissertations and Culminating Projects

Broaching is raising issues of race, ethnicity, and culture (REC) in the counseling setting.

It answers the research question: How does the lived personal history of queer educators influence how, when, and in what ways they take up queer pedagogy? Employing a life history interview methodology, along with queer theory as a theoretical framework, this study explores intersections of the participants’ life history and their engagement in queer pedagogy to examine why and how they are driven …

Comparative Expression Of Cgmp-Dependent Protein Kinase G (Pkg) From Plasmodium And Toxoplasma, Tsopmo Asaah

Theses, Dissertations and Culminating Projects

Malaria and Toxoplasmosis are life threatening diseases to humans. The search for a cure and control of these diseases is still one of the major challenges of scientists worldwide. In this research we focused on two Malaria species; Plasmodium bergei² (Pb) and Plasmodium falciparum¹ (Pf) and also on Toxoplasma gondii. Part of the life cycle of these organisms is regulated by the enzyme cyclic GMP-dependent protein kinase G (PKG)⁴. This is our drug target in this research. We believe that inhibiting this enzyme will be a great step in fighting these diseases. In this research, we devised a comparative study …

Not Just A White People's Book Club: The Participatory Action Research Of An Educator Collaborative, Jessica E. Smedley

Theses, Dissertations and Culminating Projects

This participatory action research (PAR) study investigated the learning and action of a racial and social justice book club composed of educators within a public school district. Over several years, the group engaged in collaborative cycles of inquiry, reflection, and systemic action to deepen understanding of racism, power, and equity in education. Framed by Bronfenbrenner’s Ecological Systems Theory, Relational-Cultural Theory, and Transformative Learning Theory, this study explored how learning in community supported both personal and collective transformation. Findings highlight that the book club functioned as a relational and intellectual space where vulnerability, critical reflection, and mutual accountability fostered growth-fostering relationships …

Parent Perception Of Preschool Programs: Improving Parent Knowledge Of Preschool Programs Through Targeted Recruitment, Meredith Lynn Drake

All Dissertations

Parent knowledge of preschool enrollment processes and the benefit of early education has been an issue at Mountain Elementary. Early childhood learning opportunities are a predictor of later academic success, and it is important that parents know about the available opportunities for early learning in public schools.

The purpose of this intervention is to create a targeted parent outreach program to recruit students to the four-year-old kindergarten programs at Mountain Elementary. This study attempts to answer whether targeted outreach increases enrollment numbers at Mountain Elementary.

After conducting two parent outreach events and creating two video-based social media posts, I analyzed …

A Pilot Study Exploring Vitamin D, Mental Health, And Gastrointestinal Health In Humans, Brianna C. Williams

Master's Theses

Mental disorders are experienced by nearly one billion people worldwide. Depression is one of the most common. Treatments exist, yet a devastating 75% of individuals suffering from depression do not receive adequate treatment. An emerging treatment strategy includes exploring the connection between mental health and nutrition, which includes the areas of gut health and nutrient deficiencies. Vitamin D is obtained through food, supplements, and sunlight. Many individuals are considered deficient (25[OH]D concentrations < 12 ng/mL) or insufficient (25[OH]D concentrations < 20 ng/mL). Purpose: This study aimed to explore mental and gastrointestinal (GI) health using surveys and lipopolysaccharide binding protein (LBP) concentrations, a biomarker of GI health, in individuals considered 25(OH)D deficient (DEF) vs not deficient (N-DEF). Methods: This cross-sectional study recruited physically active participants aged 18-45 years who underwent three evaluations in one visit. Health was assessed using surveys to evaluate mental health, GI symptoms, and vitamin D intake. Serum from fasting blood samples was used with an enzyme-linked immunosorbent assay to determine 25(OH)D and LBP concentrations. Unpaired t-tests were used to compare DEF vs N-DEF and significance was set at p < 0.05. Results: Thirty-two participants (mean age 25.3 ± 6.3 years) with mean and body fat percentage of 24.0% ± 10.7%, were placed into DEF (n=16) and N-DEF (n=16) categories. Interestingly, five of the 16 participants in DEF (31%) showed some level of depression (scores ranging from mild to severe) and only two of the 16 participants in N-DEF iv (13%) scored positively in the depression category (scores ranging from mild to moderate). Additionally, the participant with the lowest 25(OH)D concentration (5.42 ng/mL) was the only participant to meet the “severe” depression category criteria, with a score of 24 compared to other participants who scored within 0-16. Also, the only participant who scored “severe” in the stress category, was in the bottom 20% of 25(OH)D concentrations. As for GI health, the difference between average GI scores and average serum LBP concentrations between the groups were not statistically significant. Conclusion: There were no significant differences between DEF and N-DEF in perceived depression (p = 0.16), anxiety (p = 1.0), stress (p = 0.96), GI symptoms (P values ranged from 0.27 to 1.00), nor in LBP concentrations (p = 0.77). Funding: Support was received from the Graduate Student Association and College of Natural Health Sciences at the University of Northern Colorado.

The Latin Exclusion: Examining The Eu And The White House’S Policy Favoritism Toward Migrant Sending Latin American Nations While Punishing Similar Pressures Globally, Nicolas Garon

Notre Dame Journal of International & Comparative Law

Too often, negative perceptions of a country, whether from its government or a few citizens, result in broad restrictions applied to all nationals, either formally through policy or informally through officials’ discretion. A global norm persists in which nationals from poorer countries facing migratory pressures are subjected to heightened scrutiny and restrictive measures that deter movement to wealthier nations. Regardless of how liberal a receiving country may claim to be, states consistently adopt conservative stances on migration. Western nations, as primary destinations, often impose the harshest measures, such as travel bans and additional visa requirements, frequently based on speculative migration …

Punishment In “Disneyland”: A Magical Review Of Singaporean Sentencing Law, Policy & Practice, Lucas Brolin

Notre Dame Journal of International & Comparative Law

Staying in Singapore is like visiting Disneyland, with a catch: Imagine indulging in the world’s most magical place, but Jeffrey Katzenberg gives you a walloping if you cut in line. Deploying this self-described “winning formula,” Singapore quickly rose to prosperity. Admirers and critics mutually note Singapore’s cleanliness, safety, and efficiency. Empirical metrics suggest these accolades are not anecdotal: Singapore scores at the top of global development indexes, boasts a low crime rate and high judicial clearance rate, has comprehensive infrastructure, clean public facilities and streets, and more. Singapore’s governance is rightly credited for its prosperous outcomes. However, it also invites …

“Economic Abuse” As An Element Of Domestic Violence Against Women: A Comparative Analysis Of Sri Lanka And United Kingdom, Pavithra Rajendran

Notre Dame Journal of International & Comparative Law

Economic abuse, though not a new concept in commercial law, remains underdefined and underutilized in the context of domestic violence, particularly violence against women. Recent scholarly discussions emphasize the need for a clear definition of economic abuse in this context: "Economic abuse entails a deliberate pattern of control where individuals disrupt their partner's ability to acquire, use, and maintain economic resources." This highlights economic abuse as a powerful tool of control, with perpetrators employing various strategies to assert dominance. Scholars often distinguish economic abuse from financial abuse, a crucial differentiation, especially with the recent enactment of the United Kingdom’s Domestic …

Examining Associations Between Internalized Racism, Psychological Flexibility, And Well-Being Among Bipoc, Cerella Chandra

Dissertations

Internalized racism has been defined as the adoption of negative stereotypes related to one’s racial/ethnic group and associated with psychological distress. There is little research on the effectiveness of Acceptance and Commitment Therapy (ACT) on diverse populations, but recent intervention studies have indicated that psychological flexibility may counter the negative psychological effects of self-stigma. The purpose of this study was to examine the relationship between internalized racism, psychological flexibility, and psychological distress and life satisfaction among Black, Indigenous, and People of Color (BIPOC). Self-report data was collected using Qualtrics with prospective participants recruited from a large public university in the …
