A Machine Learning And Artificial Intelligence Sentiment Analysis Of Esg Disclosures, John Barnett Davis

Graduate Theses and Dissertations (2019 - present)

This dissertation examines whether environmental, social, and governance (ESG) disclosure sentiment extracted from SEC Form 10-K Item 1A risk disclosures aligns with Bloomberg ESG scores. The study combines SEC textual disclosures, Bloomberg ESG ratings, firm financial data, executive compensation data, and executive gender characteristics. Natural language processing and artificial intelligence methods, including FinBERT, Loughran-McDonald sentiment measures, BART-MNLI zero-shot classification, LLaMA-based ESG scoring, and readability analysis, are used to evaluate ESG-related disclosure signals. Results reveal that SEC 10-K Item 1A risk-factor sentiment and Bloomberg ESG scores represent related but distinct constructs. ESG sentiment in Item 1A is poorly aligned with third-party …

Beyond Beliefs: Factors That Shape Agricultural Plastic End-Of-Life Management Among California Strawberry Growers, Kyle Y. Cahitas

Master's Theses

The practice of using plastics in agriculture is so prevalent it has earned its own name: plasticulture. One key plasticulture tool is polyethylene (PE) mulch film, a thin plastic sheet laid over the field for a single growing season and pulled out before the next. Because PE film is hard to recycle, most of it ends up in a landfill, yet how growers decide what happens to used plastic mulch has rarely been studied. To identify what shapes that decision, this study draws on a survey of California strawberry growers (n = 126). Twenty variables, spanning grower attitudes, farm characteristics, …

Testing P300-Based Biometric Authentication Paradigms, Jordan Razzak

Electronic Theses and Dissertations

Bench research suggests that P300 amplitude is greater in response to self-relevant stimuli compared to familiar stimuli. This effect could enable a novel method of biometric authentication based on the self-relevant P300. This dissertation aims to: (1) determine the optimal presentation paradigm for leveraging self-relevance in P300-based biometric authentication, and (2) investigate P300 responses from self-relevant stimuli versus stimuli learned over the course of a week.

Two presentation paradigms were compared – rapid serial visual presentation (RSVP) and matrix presentation (MP). Participant-specific RSVP and MP classifiers were trained by applying stepwise linear discriminant analysis to data collected during presentations of …

Social Workers’ Lived Experiences Of Trauma-Informed Training, Ashley Ann Johnson

Walden Dissertations and Doctoral Studies

Social workers report limited formal training in trauma-informed approaches, and implementation of trauma-informed care varies widely across settings, with inconsistent training uptake and organizational support for sustained practice change. The purpose of this qualitative phenomenological study was to explore the lived experiences of social workers in trauma-informed training. The study was guided by trauma-informed care principles and an experiential learning framework. The research question examined how social workers develop trauma-informed competence and how systemic factors influence practice. Data were collected through 11 semi structured interviews with social workers and analyzed using thematic analysis. Three key themes emerged: (a) trauma-informed competence …

Park Visitor Education And Landscape Conservation: Evaluating Education-Based Strategies To Mitigate Visitor-Caused Damage In Goblin Valley State Park, Jason Beukers

All Graduate Reports and Creative Projects, Fall 2023 to Present

Goblin Valley State Park contains rare and highly fragile geological formations that are increasingly impacted through visitor-caused damage. While the park’s open-range management approach enhances recreational freedom and the visitor experience, it also leaves vulnerable hoodoo formations susceptible to vandalism and damage by visitor behavior and exploration. Balancing public access with landscape preservation remains a persistent challenge, particularly in large, protected areas where staffing, enforcement, and management resources are limited. This thesis reviews the effectiveness of management strategies, particularly education-based strategies such as signage and visitor messaging, in reducing depreciative visitor behaviors in national and state parks and other protected …

The Legend Of The Bear Lake Monster, Melissa Anderson Asay

All Graduate Reports and Creative Projects, Fall 2023 to Present

The Bear Lake Monster is a legend that has persisted for centuries. This monster is rooted in Shoshone oral traditions and hold the potential to be based off of fossils found in the Shoshone territory. This living legend was later amplified by Mormon settlers. One settler in particular, Joseph C. Rich, played a significant role in shaping its narrative. Though he eventually admitted to fabricating sightings to encourage settlement, belief in the creature remains alive today. The serpent’s presence in local lore has undeniably influenced the Bear Lake region, shaping both its identity and tourism industry. This legend serves as …

Parametric Assessment Of Nicotine Vapor Self-Administration In Rats, Tiffany Alexandra Gonzalez-Gutierrez

Open Access Theses & Dissertations

The increasing prevalence of electronic cigarette (e-cigarette) use among adolescents highlights the need to identify factors that promote nicotine vapor use in populations most susceptible to its long-term consequences. This requires translationally relevant animal models of nicotine vapor self-administration (VSA). Accordingly, the goal of this dissertation was to evaluate 2 key factors hypothesized to influence nicotine VSA in rats, including age and e-liquid vehicle composition. Given recent mandates on studying sex as a biological variable, the present work included both female and male rats. Aim 1 compared VSA behavior during adolescence (adolescent-onset) or adulthood (adult-onset) in groups that received vapor …

The Augmented Matching Law, Matias A. Avellaneda

All Graduate Theses and Dissertations, Fall 2023 to Present

Every living organism, including humans, has a finite amount of time available: 24 hours in a day, 365 days in a year, and a certain number of years in its life. At every moment, such an organism will be engaging in one of a multitude of possible activities, such as eating, sleeping, or reading this dissertation. We use the term choice to denote the way in which the organism distributes its time among all these activities, and some of these choice patterns are more beneficial to the organism than others, showcasing the importance of understanding the mechanisms underlying choice. A …

The Impact Of Early Exposure To Engineering Concepts In The Form Of Family, School Classes, And Stem Extracurriculars On The Long-Term Sense Of Belonging In Undergraduate Women In Engineering, Hannah Lloyd

All Graduate Theses and Dissertations, Fall 2023 to Present

Engineering continues to struggle with the underrepresentation of women, and many women who begin engineering programs report feeling isolated or uncertain about whether they belong. A strong sense of belonging has been linked to greater confidence, persistence, and success in engineering. This study examined how early experiences with engineering before college may influence students' sense of belonging later in their undergraduate engineering programs.

Using survey responses from undergraduate engineering students across the United States, this study explored several types of early exposure to engineering, including family influence, school-based engineering and STEM courses, extracurricular programs such as robotics clubs and engineering …

Comparing Error Correction Strategies In Discrete Trial Training For Children With Autism, Rachael Litchford

All Graduate Theses and Dissertations, Fall 2023 to Present

Children diagnosed with Autism Spectrum Disorder (ASD) often require structured, evidence-based teaching methods to promote skill acquisition. Discrete Trial Training (DTT) is one such approach widely used in Applied Behavior Analysis (ABA) to teach skills through repeated learning opportunities. However, limited research has compared the efficiency of specific error correction procedures within DTT. This study examined the comparative effectiveness of two error correction strategies, Active Student Response (ASR) and Model-Only, when acquiring tacting skills for children ages 2-10 with ASD. An alternating treatments design (ATD) was used to evaluate each strategy’s impact on skill acquisition, as measured by the percentage …

Pavlovian Conditioning And Self-Control: From Laboratory To Classroom Application, Saba Mahmoudi

All Graduate Theses and Dissertations, Fall 2023 to Present

Impulsive choice, the preference for a smaller-sooner reward (SSR) over a larger-later reward (LLR), is associated with various challenging behaviors (e.g., gambling and substance-used disorders). Many interventions can reduce impulsive choice but those that produce long-lasting effects typically require long training durations or are difficult to implement in applied settings. This dissertation evaluated a novel Pavlovian training approach designed to promote self-control. In Experiment 1, procedures from Mahmoudi and Madden (2024) were replicated in the laboratory with the addition of a truly random control group. The study also assessed whether presenting the conditioned stimulus (CS) before a choice would increase …

Effects Of Single-Session Interventions On Youth Internalizing Problems, Thomas K. Franzmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Anxiety and depression are among the most common mental health concerns young people face, and they often interfere with school, friendships, family life, and long-term well-being. Even though effective therapies exist, only about half of youth who need care ever receive it, and among those who do start treatment, the most common total number of sessions a young person attends is one. This gap between what young people need and what they actually receive raises a practical question for the field: can a single, well-designed meeting with a provider produce meaningful change for some youth and families, and what should …

Impact Of Chronic Stress And Nutrition On Functional Connectivity And Neural Networks In Young Kichwa Children From The Ecuadorian Amazon Rainforest, Matthew L. Cook

All Graduate Theses and Dissertations, Fall 2023 to Present

Early childhood is a critical period for brain development. Positive and negative experiences during this time can have lasting effects on learning, health, and well-being. However, most research on children’s brain development has been conducted in wealthy, industrialized nations, leaving important gaps in our understanding of how children develop in other cultural and environmental contexts.

This study examined brain development in Indigenous Kichwa children living in two rural communities in the Ecuadorian Amazon Rainforest. The goal was to better understand how chronic stress and nutrition may influence a child’s developing brain during early childhood. Children participated in noninvasive brain assessments …

Faculty Perspectives On Career And Technical Education Programming For Prison And Other At-Risk Populations: Implications Of A Human Centered Design Focus, Taija R. Jackson

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this quantitative, cross-sectional, quasi-experimental study was to examine the perceptions of career and technical education (CTE) faculty regarding their familiarity with human-centered design (HCD), perceptions of the value and worth as a framework for program and curriculum design and willingness to teach in correctional education settings. The survey was administered to postsecondary CTE employed at public community and technical colleges in Utah and Colorado (N = 37). Participants were randomly assigned to either a treatment condition, in which they viewed a six-minute-long video vignette illustrating HCD in practice, or a control condition without exposure to the …

Developing A New Uas Method For Estimating Heat Exposure On Western Us Trails, Jared Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Heat exposure and the risks to human health that stem from it have been studied extensively in the context of urban and occupational settings. Less studied however, is the effect of heat exposure in a recreational setting such as on hiking trails. What makes this fact more surprising is that recreation, especially in the Western US, is extremely popular, with national parks such as Zion and Arches bringing in hundreds of thousands of visitors every year. With millions of recreationists exposed to the hazard of heat every year, it is critical that recreationists are made aware of the dangers they …

Mindful Classrooms: Teachers Co-Designing And Implementing Mindfulness Interventions, Mary L. Phan

All Graduate Theses and Dissertations, Fall 2023 to Present

Teachers play a critical role in supporting student learning and well-being, yet many experience high levels of stress, burnout, and increasing job demands. Stress can negatively affect teachers’ mental health, job satisfaction, and classroom environments, making it important to identify practical and sustainable ways to support teacher well being. Mindfulness practices, which encourage individuals to focus on the present moment with awareness and acceptance, have shown promise for reducing stress and improving emotional well-being. However, little is known about how mindfulness programs can be adapted to fit the realities of elementary school classrooms and whether teachers can successfully implement these …

Patterns Of Presidential Executive Orders And Democratic Quality: Evidence From The United States, 2017-2025, Karyn Sofie Sanford

All Graduate Theses and Dissertations, Fall 2023 to Present

Democratic backsliding has become an increasingly prominent topic in political science, yet relatively little attention has been devoted to how observable expressions of executive authority correspond with changes in democratic quality. Using the United States as a case study, this study examines the relationship between presidential executive orders and democratic quality from 2017 to 2025. More specifically, it investigates whether characteristics of executive orders correspond with changes in democratic quality, measured using the Liberal Democracy Index and the Judicial Constraints Index from the Varieties of Democracy (V-Dem) Project.

Presidential executive order issued between 2017 and 2025 were collected from the …

Gender And Bill Changes In Congress: An Analysis Of Women-Sponsored And Women's Issue Bills, Kipling B. Corry

All Graduate Theses and Dissertations, Fall 2023 to Present

Women have faced historical disadvantages in American politics, generally, and in their positions as lawmakers. Bills in Congress, proposed by men and women alike, often undergo various textual changes before becoming law. This thesis explores how the gender of lawmakers and the gendered issues found within bills affect these changes. Are bills that are proposed by women disproportionately altered more than bills proposed by men? And are bills that concern women’s policy issues disproportionately altered more than bills that do not? This thesis investigates these questions by first presenting two original datasets and a full bill text file that introduce …

Daily Consumer Expenditures And Income: New Evidence From A Payment Diary, Shaun Gilyard, Scott Schuh

Economics Faculty Working Papers Series

This paper demonstrates that unique daily consumption and income transactions data derived from the Diary of Consumer Payment Choice (DCPC) produced unplanned benefits: they cover high percentages of U.S. data, forecast well in real time, offer new insights to payday and pay-cycle effects, and suggest selection effects in convenience samples of transactions data. Relative to other transactions data, DCPC data are more representative, publicly available, and offers other advantages. Daily data more clearly exhibit three explicit features largely absent from lower frequencies: 1) discrepancy between consumption and expenditures; 2) discrete expenditures and income; and 3) asynchronous consumer expenditures (daily) and …

From Personal To Personalized Goals: How Goal Nudges Improve Production, Joaquín Gómez-Miñambres, Brice Corgnet, Roberto Hernán González

ESI Working Papers

We study how workers’ non-binding self-set goals affect their production and whether goal nudges (ability-calibrated goal hints) make goal setting more effective. In a real-effort task, participants first complete an ability pretest and are then assigned to one of three treatments: a no-goal baseline, a personal goal treatment with no external hint, or a personalized goal nudge that participants may accept or modify. We document a positive link between goals and production. However, merely asking workers to set goals is ineffective: when left unguided, workers anchor on conservative goals well below those induced by goal nudges, leading to underperformance. In …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

When Does Emigration Reduce Domestic Economic Activities? Evidence On The Loss Of Management Capacity From A Visa Lottery, Marup Hossain, Ahmed Mushfiq Mobarak

Discussion Papers

Economic development is often conceived as structural transformation and migration out of rural agriculture (Lewis, 1954; Fei & Ranis, 1964). Understanding development therefore requires us to identify how rural economies transform in response to emigration. We study how international migration reshapes domestic economic activity in origin households using a randomized visa lottery that gave Bangladeshi men job opportunities in Malaysia. Winning the lottery raises total household income through remittances, but income earned in Bangladesh declines due to contractions in nonfarm business activity. In contrast, crop income remains stable despite large reductions in agricultural input expenditures, because farming gets delegated through …

Liah Greenfeld: Scholar, Thinker, Friend, Joseph Drew

Comparative Civilizations Review

Professor Liah Greenfeld and I met several years ago when she submitted an article to the Comparative Civilizations Review. Her thoughtful demeanor and personal kindness to all were quickly evident, but so, too, was her scholarship, especially her probing theories of state, society, and civilization.

The Effect Of Childcare On Female Labor Supply And Child Development In Low And Middle Income Countries, Serena Goldberg, Costas Meghir

Discussion Papers

Childcare services can offer an opportunity for women to develop their careers and increase household income. At the same time, it can affect the development of children, depending on the quality of care. We first develop a collective model of the household as a conceptual framework to show how improving the availability of childcare can affect mothers’ labor market opportunities and earnings and how it can affect child development. We then review the literature on the effects of childcare on the employment and earnings of women and on child development. Childcare can increase mothers’ employment. However, limited work opportunities or …

Broadening Participation In Computing: Retention Pathways For Supporting Underrepresented Students, Oluwafemi Osho

All Dissertations

The computing sector's rapid growth has intensified demand for computing professionals, yet undergraduate computer science (CS) programs continue to lose substantial numbers of students, often within the first two years, before they reach degree completion. Attrition is not evenly distributed: women and other underrepresented minority (URM) students remain less likely to persist in CS despite broader increases in enrollment. These persistent disparities suggest the need to understand not only how to broaden entry into computing but also how students' experiences within programs shape retention over time. In this dissertation, I address this critical challenge by focusing on identifying inclusive strategies …

The Confluence Of Conflict-Induced Vulnerability, Organized Crime, And Sex Trafficking In Receiving States: A South African Civil Society Perspective, Monique Emser

Dignity: A Journal of Analysis of Exploitation and Violence

The crime-conflict nexus has been well-documented in conflict-affected and post-conflict states. Criminal networks make use of manifold methods and strategies to exploit individual and structural vulnerabilities, particularly those affected by war, displacement, and precarious migration journeys, forming the backbone of most conflict-induced trafficking ecosystems, whether in countries of origin, transit, or receipt. This article examines the intersection of sex trafficking, diaspora communities, and organized crime within South Africa as a receiving state from a civil society perspective. It underscores the deficiencies in traditional, reductionist, enforcement-based approaches to counter-trafficking by the state, where nested subsystems, such as those produced by endemic …

The Nature Of Human Trafficking Enterprises: Analysis Of U.S. And International Prosecutions--And The Path Forward, Jay Albanese

Dignity: A Journal of Analysis of Exploitation and Violence

The primary objective of this research is to develop a description and typology of the nature of serious cases of human trafficking and how traffickers, their victims, and consumers (the demand) overlap and interact across locations. This study examines known human trafficking enterprises for which sufficient evidence has been obtained to result in prosecution. These are also serious cases because US federal and international prosecutions result when the offenses are interstate or international in scope. Using a sample of US cases prosecuted over three calendar years (2021-2024), combined with an international sample of cases, an effort is made to develop …
