Evaluating The Predictive Value Of Basc-3 Anxiety Scale And Working Memory Index Scores For Clinically Significant Test Anxiety: A Comprehensive Analysis Of Non-Classifiable Cases, Des'tiana S. Williams

Electronic Theses and Dissertations

This dissertation will explore how test anxiety (TA) affects working memory (WM) and whether certain factors can help predict higher levels of test anxiety. Anxiety has been defined as a common experience that can show up in various forms—like general worry, social fears, panic attacks, and specific phobias (APA, 2022). It was described as often triggering our natural “fight-or-flight” response, which can impact our ability to focus, think clearly, and remember things. For students, test anxiety has been especially challenging, affecting how they perform in high-stakes academic settings. Using data from a university based psychological assessment center, this study will …

Collaboration Across The Silos: Consultation As A Means For Integrating Services For Twice-Exceptional Learners, Kimberly Bowers Yoshino

Electronic Theses and Dissertations

Twice-exceptional (2e) learners are underserved in American schools. As students who demonstrate both giftedness and disabilities, 2e learners maintain profiles that warrant tailored educational services across special and gifted education programs. Yet, these programs are considered institutionally mutually exclusive as legal mandates create de facto isolation — the antithesis of what is recommended for the students’ optimal development. School psychologists have been identified as professionals critically positioned to support 2e learners because of their specialized skill set, namely in consultation. However, little is known about their consultative practices with the educators who serve 2e learners or how they traverse school …

Young Adults’ Metaperceptions Of Their Childhood Caregivers’ Appraisals And Young Adulthood Mental Health, Cassandra Svelnys

Electronic Theses and Dissertations

Early experiences and relationships have enduring impacts on the development of self and later mental health and wellbeing. In social relationships and interactions, the developing individual is continuously assessing how they view themself, how they view the other person, and how they believe the other person views them. Metaperceptions represent the latter construct: how an individual thinks another person perceives them. Childhood self-esteem, parent-child attachment, and metaperceptions are foundational constructs for the developing individual, yet metaperceptions have not previously been tested as a predictor for adulthood mental health while also accounting for childhood self-esteem and parent-child attachment. This study introduced …

Who Gets To Be A Child And When? The Pervasive Yet Contextually Shaped Nature Of Racialized Adultification Across Perceivers And Contexts, Kevin M. Summers

Electronic Theses and Dissertations

Racialized adultification is a pervasive bias in which individuals tend to judge Black children as older and more adult-like than White children of the same age. This racial bias is discussed across many scientific domains in addition to popular media, yet there is relatively little empirical work documenting its existence, consequences, and boundary conditions. In the current work, I aim to develop an empirical foundation that advances scientific understanding of racialized adultification and in turn contributes to a growing model that elucidates the conditions under which individuals are disproportionately likely to express this pernicious bias. In the current work, I …

These findings underscore the effectiveness of combining traditional audio processing with modern machine learning, offering promising applications …

Enhancing Multi-Step Stock Price Forecasting With Social Media Sentiment And Engagement Metrics, Damilare Olaniyan

Electronic Theses and Dissertations

This thesis investigates whether social media sentiment can improve the accuracy of stock price prediction beyond traditional historical data. While financial markets have long relied on structured numerical indicators, the growing influence of public discourse on platforms like Twitter has introduced new opportunities for extracting market-relevant signals from unstructured text. The study focuses on four major technology firms and combines sentiment features derived from Twitter with historical stock prices in a hybrid machine learning framework. Engagement-weighted sentiment, linguistic complexity, and polarity intensity were extracted using natural language processing techniques and incorporated into classification and regression models. Results show that including …

Artists In The Alternative Genre: Communication Through Music, C. L. Noë

Electronic Theses and Dissertations

Musicians throughout time and genre have strived to connect with their audience through music, whether they are trying to communicate a story or their own unique style. Musicians in alternative rock genres are no different, and therefore, this thesis looks at three different bands and analyzes the ways they convey meaning through their music for their audiences. Starting with Green Day, in the American Idiot album, they communicate the inner turmoil of the characters through a rhythmic motif and the different ways it presents in the music. Next, Fall Out Boy communicates authenticity to their fans through lyrics, vocal style, …

Collaborative Federated Learning For Robots In Heterogeneous Environments, Karlan Schneider

Electronic Theses and Dissertations

This research investigates the performance of Federated Averaging (FedAvg) in simulated Federated Learning (FL) scenarios with varying degrees of environmental heterogeneity among robotic agents. The study explores the impact of data heterogeneity on both the convergence of FedAvg and the fairness of learning, with regard to consistency of performance across agents. Experiments were conducted with simulated robots trained to perform a target collection task, where a subset of agents encountered an unfamiliar environment. The results demonstrate that while FedAvg exhibits resilience to the introduction of new environmental data, it struggles to ensure both convergence and fairness in heterogeneous settings. Specifically, …

Photochemistry Of Quinones And Combustion-Derived Particles, Desiree J. Sarmiento

Electronic Theses and Dissertations

Quinones are ubiquitous species that can be produced from the photochemical aging of combustion-derived particles (CDPs). Polycyclic aromatic hydrocarbons (PAHs) are a major component of CDPs and are precursors to quinones and other oxidized products (OPAHs). My work first expanded on the PAH and OPAH photochemistry research of Dr. John Haynes, who showed that anthracene (ANT) oxidizes into 1,4-naphthoquinone (1,4-NAPQ), 1,4-anthraquinone (1,4-ANTQ), and 9,10-anthraquinone (9,10-ANTQ), and of Dr. Heather Runberg, who demonstrated the ability of ANT and these quinones to generate reactive oxygen species (ROS). Then at the Pacific Northwest National Laboratory (PNNL), I was given the opportunity to investigate …

The Role Of Adolescent Depression Heterogeneity And Resilience Resources In Adulthood Cardiometabolic Health And Depressive Symptoms, Samantha R. Scott

Electronic Theses and Dissertations

Depression in adolescence is a major public health problem and is a risk factor for early-onset cardiometabolic disease. Although adolescent depression is a risk factor for poor cardiometabolic health, depression is heterogeneous and associations may differ by sex. Additionally, if risk factors such as depression can predict adulthood cardiometabolic health, resilience factors (e.g., social, school, neighborhood) that are protective for depression may also be protective for physical health, but this is an ongoing area of research. The goals of the current dissertation were to gain a better understanding of what depressive symptom presentations in adolescents are most concerning for adulthood …

Harlem’S Avenues For Agency: An Exploration Of Black Female Agency In Angelina Weld Grimké And Zora Neale Hurston’S Short Stories, Jessica Ellen Hartenbower

Electronic Theses and Dissertations

This thesis explores themes of Black female agency in selected short stories by Angelina Weld Grimké and Zora Neale Hurston. Pushing back against the belief that the Harlem Renaissaince was a movement solely for male artists, Grimké and Hurston write short stories that center Black women and their experiences. Through the avenues of bodily autonomy, the using or silencing of voice, the opportunity and ability to make choices, issues of justice, retribution, and vengeance, the holding of authority, and being empowered or disempowered, I examine the female characters’ exercising of their agency to varying degrees. I also discuss how religious …

Interactive Read-Alouds Of Translingual Texts As A Catalyst For Literacy Engagement Among Emergent Bilingual Elementary Students: A Case Study, Anna Handy

Electronic Theses and Dissertations

While the population of emergent bilingual students continues to increase in U.S. schools, the teaching force remains predominantly White and monolingual, with many educators underprepared in how to support emergent bilingual students’ literacy development or sustain their diverse linguistic practices. This is reflected in longstanding gaps in performance between monolingual and multilingual students on standardized assessments of reading. The purpose of this qualitative case study was to explore one possible approach to increase emergent bilingual students’ engagement during and response to literacy instruction: interactive read-alouds of children’s books that incorporate translanguaging. This study sought to describe and interpret how emergent …

A Ritual Of Institutions: The State Industrial School In Golden, Colorado And The Shaping Of American Youth, Cyndal Groskopf

Electronic Theses and Dissertations

This thesis investigates the Colorado State Industrial School as a ritualistic institution that influenced boys aged 7 to 19 through Americanization practices between 1881 and 1930. By employing primary documentation, drone imagery, and LiDAR technology, the study examines how cultural and physical activities, along with personal statements, described and maintained the ritualized nature among these incarcerated youth. The findings reveal how institutional routines and activities reinforced narratives of American identity, particularly in relation to themes of personal identity, conformity, and agency. These rituals played a crucial role in institutionalizing cultural ideals and shaping the identities of marginalized youth. The research …

Movement As Metamorphosis: An Examination Of Transformative Learning In Dance, Whitney Egstad

Electronic Theses and Dissertations

Using the arts-based methodology of Educational Criticism and Connoisseurship (Uhrmacher, Moroye, & Flinders, 2017) to examine the curriculum and pedagogy of a Colorado-based dance studio, this qualitative dissertation explores how transformative learning (TL) unfolds within the context of adult dance education. Grounded in Mezirow’s (1991) theory of transformative learning, the study investigates how dance becomes a medium for personal transformation, identity reconstruction, and emotional healing. Data collection included six hours of interviews with instructors and students and twelve hours of class observations, focusing on how adult learners experience curriculum not just as technical instruction, but as an embodied, relational journey …

An Auto-Criticism Exploration Of An International Transracial Adoption, Jessica M. Morganfield

Electronic Theses and Dissertations

This qualitative dissertation explores the lived experience of international transracial adoption through the combined methodologies of auto-criticism and journaling. Using a first-person, insider-led approach, this study addresses four central research questions: (1) What experiences emerge when an adult adoptee reflects on their childhood as an international transracial adoptee? (2) How do identity development, cultural socialization, and experiences of racial and adoptive microaggressions intersect and influence an individual? (3) How does auto-criticism uniquely describe the international transracial adoptee experience? and (4) How might journaling serve as a research tool for data collection and analysis?

Daily journaling over a 30-day period functioned …

Optimizing Option Market Clearing, Juan Andrés Malaver Alvarado

Electronic Theses and Dissertations

Modern options markets clear each strike in isolation, leaving cross-strike arbitrage unexploited. This thesis applies a payoff-dominant clearing mechanism to realized trades—roughly 2 000 Cboe VIX option executions from June–November 2016—after classifying each trade’s side and bundling by expiration. Three optimization formulations are tested: a fractional linear program (LP), a mixed-integer LP, and a pure integer program. On a 10-core laptop every bundle solves in < 0.5 s. The LP captures the greatest surplus, yet the integer models recover nearly as much while filling whole contracts and holding only modest margin. Results reveal persistent, albeit small, inefficiencies in executed trades and demonstrate that an integral cross-strike auction could operate in real time. The accompanying C/Gurobi code is modular and readily extendable to early-exercise options. Trade-level evidence thus supports redesigning exchange clearing to consider the complete option book.

Reading Interventions In The Modern Era: Reconceptualizing The Utility Of Video Games, Senaida Mehmedovic

Electronic Theses and Dissertations

Youth in the United States continue to have difficulty developing reading skills, with only 31% of fourth graders reading at a “proficient level” (NAEP Reading: National Average Scores, 2024). Youth struggling to develop reading skills often have reading anxiety (Chow et al., 2021; Martinez, 2019; Ramirez et al., 2019), which impacts their reading skill development even more (Mohammadpur & Ghafournia, 2015); the interwoven and cyclical relationship between reading anxiety and reading comprehension requires interventions to address these needs concurrently (Francis et al., 2019; Francis et al., 2021; Grills et al., 2012). The increased avoidance and paired aversion of reading-related tasks …

The Self That Practices Deeper Teaching: An Exploration Of Influences On Teacher Beliefs And Values, Kerstin L. Rowe

Electronic Theses and Dissertations

For decades, educators have called for “a fundamental redesign of the industrial-age classroom.” However, despite ongoing discourse around educational reform, the majority of teachers still use the industrial model of education while too few teachers implement deeper teaching practices which situate students as active learners in addressing complex, real-world challenges rather than being passive recipients of knowledge. Existing literature does not explore the influences upon the beliefs and values of teachers who create deeper learning experiences.

This qualitative study employs educational criticism and connoisseurship to illuminate the inner self of those who practice deeper teaching. Drawing on in-depth observations, interviews, …

Benefits Of Extended Unemployment Insurance On Post-Unemployment Outcomes, Alyssa Roche

Electronic Theses and Dissertations

This thesis investigates how unemployment insurance (UI) affects individuals during and after unemployment. Drawing on historical evidence from recent recessions in the United States, publicly available data, behavioral insights, and mathematical modeling, it argues that the benefits of extending UI outweigh the potential costs. The analysis incorporates a wide range of sources, including empirical economic studies using regression models and psychology and business research that highlight behavioral responses to financial stress and job insecurity. By combining quantitative data with behavioral context, the thesis offers a more comprehensive understanding of how extended UI influences job search decisions, wage outcomes, and overall …

Culture And Environment: The Calling Lakes Ecomuseum As A Community Sustainability Initiative, Kace N. Anders

Electronic Theses and Dissertations

Located in Saskatchewan, Canada, the Calling Lakes Ecomuseum, CLEM, is a community-based organization focused on water management and sustainability. Ecomuseums are holistic organizations that occupy landscapes, are responsive to community needs, conserve in situ heritage, and incorporate sustainability along with community development. The ecomuseum movement came from a need for holistic heritage management that disengaged with conventional museology and created space for communities to engage with their heritage in ways that promote community identity. This thesis analyzes the Calling Lakes Ecomuseum and how it utilizes the ecomuseum concept alongside environmental sustainability. Both semi-structured interviews and place-based field observations were used …

The Islamic Orient In Antebellum America: The Influence Of Edgar Allan Poe In Contemporary Arabic Literature, Sohaib Alkamal

Electronic Theses and Dissertations

This dissertation posits a comprehensive overview of the debate about Orientalism, particularly early American depictions of the Islamic Orient. The study investigates the antebellum American portrayal of the Islamic Orient, focusing on Edgar Allan Poe’s Orientalist readings. While Said’s Orientalism concentrates heavily on aspects of power in West-East relations throughout history, this study expands on several aspects of Said’s book. This study provides a new approach to exploring the field of Orientalism by giving a voice to Arabic sources that are absent in Said’s Orientalism and rarely known to Western audiences. Such sources are medieval Islamic sources, which include phantasies …

Representation Of Diseases And Health Care In Selected African Gyno-Texts, Rachael K. Aderoju

Electronic Theses and Dissertations

This study explores the interdisciplinary field of literature and medicine through a feminist psychoanalytic lens, focusing on how Nigerian female writers represent illness, healthcare, and medical ethics in post-independence gyno-texts. Traditionally, scholarship in this field has centered on andro-texts (literary works authored by men), leaving a critical gap in the exploration of women’s perspectives. This research addresses that gap by analyzing nine prose works authored by Nigerian women, including texts by Chimamanda Ngozi Adichie, Ayobami Adebayo, Lola Shoneyin, and Samira Haruna Sanusi. These texts are examined for their portrayal of diseases such as infertility, cancer, bipolar disorder, and renal failure, …

Political Ecologies Of The Livestock Industry, Jecca Bowen

Electronic Theses and Dissertations

In the United States today, livestock production is dominated by an intensified, industrialized production paradigm whose growth in recent decades has utterly transformed the logistical realities and community impacts of animal agriculture. This dissertation investigates the effects of this production paradigm on livestock producers—whose decision-making is shaped by multi-scalar and often contradictory forces—as well as residents living near these large operations. To do so, I draw upon mixed-methods fieldwork, including in-depth interviews, spatial analysis, and field odor measurements in Weld and Morgan Counties in northern Colorado. I also use political ecologies of emotion, embodiment, and health to examine the complex …

Exploring The Effects Of Africana Studies On Black Undergraduate Students: A Qualitative Case Study, Lanaya M. Butler

Electronic Theses and Dissertations

Particularly in the context of American K-12 schools, education has been manipulated to control—rather than liberate—students through the erasure and distortion of Black history, experiences, perspectives, and capabilities. Additionally, American schools prioritize memorization and obedience while failing to equip students with critical thinking skills. As a result, students are trained to become workers rather than innovators, worldbuilders, and change-makers. For nearly a century, Black educational critics have stated that these systems were designed to subjugate Black community members through dehumanization and enslavement of the mind. These critiques are foundational to the aims of Afrocentric education which posits the life experiences …

Margaret Cavendish And Radical Self-Love, Marina Burandt

Electronic Theses and Dissertations

Margaret Cavendish was an early modern Englishwoman writer who lived from 1623 to 1673. She wrote under her own name at a time when it was more common for women to write under a pen name, and published almost everything she wrote. Her writings include a multiplicity of genres, from science fiction, poetry, drama, and philosophy, to letters, biography, and autobiography. Cavendish’s style often blends multiple genres and forms, showcasing a modality that is driven by complexity and hybridity. Cavendish was a surprisingly modern figure in many ways, as her writings show. The Description of a New World, Called the …

Conceptualizing The Explanatory Fully Longitudinal Mixed Methods Case Study Design: A Demonstration With An Arithmetic Education Trial With Kindergarten Children, Menglong Cong

Electronic Theses and Dissertations

In employing longitudinal mixed methods designs, researchers have commonly used the fully longitudinal mixed methods design. This has occurred mostly in the health sciences but less in education. The current investigation proposes a novel longitudinal mixed methods research design, explanatory fully longitudinal mixed methods case study design. It demonstrates its potential for addressing research inquiries in educational research using the arithmetic learning trajectories datasets. This study is presented in three components. The first is a quantitative phase, selecting an exploratory case from a previous arithmetic learning trajectories study (Clements et al., 2021) for qualitative analyses based on maximizing the …

Computational Fluid Dynamics And Fluid Structure Interaction Modeling In Healthy Vertebral Arteries: A Comparative Study, Bryce Clinkenbeard

Electronic Theses and Dissertations

Cerebral perfusion is critical for maintaining proper brain function, with each cerebrovascular artery playing an integral role in the overall cerebrovascular system. When these arteries become damaged or develop plaque, cardiovascular disease (CVDs) such as atherosclerosis can arise, leading to conditions like arterial stenosis. While CVDs are most prevalent in older individuals, they are also observed in young adults, particularly those engaged in high-endurance occupations such as military service. Diagnosis and prediction of CVDs often rely on imaging modalities supported by computational fluid dynamics (CFD) which account for low resolution in fluid flow. CFD models assume rigid arterial walls, which …

Minority Stressors And Internalizing Symptoms In Sexual And Gender Minority Adolescents: A Systematic Review And Meta-Analysis, Anni R. Subar

Electronic Theses and Dissertations

Sexual and gender minority (SGM) adolescents are at elevated risk for internalizing symptoms, such as anxiety and depression, due in part to chronic exposure to minority stress. To provide a comprehensive synthesis of this literature, we conducted a meta-analysis of 32 studies, yielding 162 effect sizes from 41,360 participants aged 8– 22. All included studies examined the association between minority stress, defined as stigma-related stressors such as discrimination, victimization, and internalized stigma, and internalizing outcomes in SGM youth. The random-effects meta-analysis revealed a small but significant association (r = .25) between minority stress and internalizing symptoms, consistent across stressor …

Development Of An Embedded Iot Board For Real-Time Floor Estimation Of Autonomous Robots, Carter J. Sorensen

Electronic Theses and Dissertations

As service robots become more prevalent in multi-story environments such as hospitals, hotels, and laboratories, accurate floor-level detection is critical to ensuring operational reliability. Consider a robot tasked with delivering medical samples in a multi-story laboratory. Without accurate feedback, a robot exiting on the wrong floor could introduce delays, disrupt workflows, or compromise sample integrity. Internet of Things (IoT) technologies offer a way to address these risks by providing real-time error detection and corrective capability. However, current IoT-based floor estimation systems often require invasive modifications to building infrastructure—particularly elevator control panels. These approaches introduce challenges related to cost, liability, backward …
