Resisting The Historical And Geographical “Other”: The Role Of Expertise In Video Game Music, Tommy Dainko

Electronic Theses and Dissertations

Video games create rich, virtual worlds for players to explore. Game developers have often utilized exoticism, allowing players to experience the “Other” from the comfort of home. Music is a powerful tool to evoke Otherness and can reinforce stereotypes about the past and different cultures. This thesis looks at recent games where developers have collaborated with expert musicians either from the culture depicted or with expertise in historical performance practices. I document two purposes these collaborations can serve. First, the use of expert musicians creates a veneer of authenticity allowing developers to market the games as “authentic” experiences. Second, these …

Ensemble Perception Of Emotion: Incidental Effects Of Social Identity, Spencer T. Dobbs

Electronic Theses and Dissertations

Research in vision science suggests that people possess a perceptual mechanism – ensemble perception - which enables them to rapidly identify the characteristics of groups (e.g., emotion, sex-ratio, race-ratio). This work examined whether ensemble perceptions of groups are driven by the characteristics of group members whose behavior is most likely to impact the perceiver. Specifically, we predicted that more self-relevant group members would be weighted more heavily in ensemble perceptions than less self-relevant group members. Study 1 (n = 83) found that young adult participants’ ensemble perceptions of emotion were biased in favor of more self-relevant (younger adult) group …

Youth Offending In Denver: The Increasing Trend And Essential Elements To Successful Intervention, Olivia Crimaldi

Undergraduate Theses, Capstones, and Recitals

Recent years have witnessed an alarming increase in youth offending across Denver, necessitating a thorough analysis of factors influencing the surge, as well as areas of improvement for current intervention methods. Juvenile delinquency is largely affected by complications associated with the transition to adulthood, such as the development of personal identity or a decrease in parental supervision. A full understanding of at-risk individuals must consider risk, promotive and protective factors, as well as the interaction between these three components. Past successful prevention and intervention methods have included relationship-building implementation, therapeutic strategies, and consistent measures of quality and accountability. Despite many …

Flower Study, Haven Hinds

Undergraduate Theses, Capstones, and Recitals

This project is a study into extinct flowers, their histories, environments, biology, colors, and assigned personalities then manifested in 3D models and a digital book. The goal was to select six flowers with interesting histories and or cultural connections. Since the flowers can, for the most part, not be seen or kept they were created in Blender as accurately as possible. To give people a means of connection with the flowers, each was assigned a personality based on different factors. These factors could be the colors they possess, where geographically they thrived, parts of their history, and biological factors. To …

Colocalization Of Odc And Amyloid Plaques In Patients With Alzheimer’S Disease And Down Syndrome, Julia S. Gielczynski

Undergraduate Theses, Capstones, and Recitals

Polyamines, and their rate-limiting enzyme ornithine decarboxylase (ODC), are crucial for many functions in the central nervous system but levels decrease with age. In neurodegenerative diseases, like Alzheimer’s Disease (AD), polyamine levels begin to increase again. Yet, there are still many unanswered questions surrounding polyamine’s possible role in AD, especially in those with Down Syndrome (DS), who also have an extra copy of the amyloid precursor protein (APP) and tend to get AD far earlier than the general population. We aim to investigate if there is colocalization between amyloid plaques and Ornithine Decarboxylase (ODC) in patients with AD and AD/DS, …

PM data was compared between individual sensors of the same type, as well as across the two different sensor …

Miss Americana: Taylor Swift As A Battleground For Feminist Discourse, Juliet Eklund

Undergraduate Theses, Capstones, and Recitals

The United States finds itself at a historical moment in which feminism is perhaps more polarizing than ever before. On the one hand, it is no longer taboo to identify as feminist; in fact, men and women alike are embracing feminist perspectives. A recent Pew Research survey found that 61% of American women identified as feminists, with this proportion even higher among Democrats and those who had received higher education (Barroso, 2020). At the same time, women are faced with more opportunities and fewer barriers to achieving success than ever before. Hillary Clinton’s 2016 presidential campaign and the 2020 election …

Investigating The Role Of Ebf3a In Craniofacial Development, Shujan A. Sharafeldeen

Undergraduate Theses, Capstones, and Recitals

Proper craniofacial development requires many genes. Single-cell RNA sequencing (scRNA-seq) allows us to identify genes expressed in precursor cells for craniofacial structures, but the function of many of these genes in craniofacial development has yet to be characterized. In our scRNA-seq of cranial neural crest cells (NCCs), which are precursor cells for the craniofacial skeleton, we found a gene called early B-cell factor 3 (ebf3a) that may be involved in craniofacial development. In our scRNA-seq data, ebf3a expression is restricted to cranial NCCs of the dorsal and ventral domains of pharyngeal arches 1 and 2. In humans, damaging variants in …

Spin And Charge Transport In Metallic Ferrimagnets And Disordered Magnetic Oxides, Leopoldo A. Hernandez

Electronic Theses and Dissertations

Recent efforts have been exploring the use of thin film synthetic ferrimagnets and disordered magnetic oxides for applications in spintronic devices. Due to the antiferromagnetic exchange interaction, ferrimagnetic materials offer the ultrafast dynamics of the antiferromagnetic exchange, with a net magnetization that can be influenced externally. With two, or more, competing ferromagnet sublattices, interesting properties arise that depend on the final magnetic landscape after growth of the material and it’s inherent magnetic anisotropy energies. Properties such as magnetic compensation temperatures, and perpendicular magnetic anisotropy are attractive for applications in spintronic memory and logic devices, some already being implemented in MRAM …

Effect Of Oxidation Of Graphene On Agglomeration And The Mechanical Properties Of Thermosetting Resins, Matthew A. Reil

Electronic Theses and Dissertations

Thermosetting resins are used extensively worldwide in applications ranging from adhesives to structural components. However, these resins generally fail in a brittle fracture mode which is undesirable in most situations. Graphene (G) and its derivatives have been considered as additives to epoxy for material property enhancement and varied results have been reported in the literature. In this work, the effects of the oxidation of G to graphene oxide (GO) on polymer interactions and plate agglomeration were studied by classical molecular dynamics (MD). Results from those simulations concluded that agglomerates were likely present in all G-based nanocomposites. The effect of these …

Electronic Theses and Dissertations

This study investigates the relationship between leadership and extreme contexts through the lens of rural hospitals facing environmental jolts. Rural hospitals offer a unique setting for this research, given their inherent geographic isolation, lack of resources, and the critical role these facilities play in their communities. Through a qualitative analysis of interviews with Chief Executive Officers of rural hospitals, this research takes a grounded approach to build theory surrounding how leadership not only shapes but is shaped by extreme contexts and environmental jolts. The research results in four primary contributions. Namely, this study extends existing typologies on leadership in extreme …

Extending The Utility Of Ant Colony Optimization Through The Incorporation Of An Intraclass Correlation Coefficient To Assess For Rater Consistency, Mark Leveling

Electronic Theses and Dissertations

Ant Colony Optimization (ACO) is a flexible algorithm designed to solve complex combinatorial problems. While the method was derived from the behavior of ants by researchers in the field of computer science, its application to solving complex combinatorial problems is widespread in a growing number of fields in behavioral science, including psychometrics. Over the last two decades, psychometricians have adapted ACO to measurement model specification problems with the intention of generating measurement models that express measurement model fit and reliability within the standards of what is considered acceptable. Additionally, psychometricians have used ACO to generate shortened versions of existing measures …

Electronic Theses and Dissertations

This study describes a qualitative study using a grounded theory, constructivist approach, which sampled (N = 6) Asian American college students who lived in the United States during the peak of the COVID-19 pandemic. Research shows that COVID significantly impacted the Asian American perception of mental health, including mental health help- seeking behaviors and discrimination experienced. The long-term effects of this are still largely unknown. In depth, semi-structured interviews were used to explore the lived experiences of these Asian Americans. Qualitative analysis revealed thematic differences for the following themes: (a) experience with mental illness, (b) mental health help- seeking …

An Exploration Of Rural Advanced Placement Differentiation, Kristin M. Shapiro

Electronic Theses and Dissertations

Advanced Placement classes are introductory college courses taught in high school. Over 60% of all secondary gifted programs report utilizing AP classes as part of their program offerings (Callahan et al., 2017). Despite the prevalence of AP courses, there is no exact match between this particular type of programming and the needs of gifted learners (Gallagher, 2008). The use and occurrence of AP programs across the United States have not been equal, with subsequent underrepresentation of underserved groups, including rural students (Gagnon & Mattingly, 2016) in AP classes. Rural gifted students benefit from all the same classroom differentiation techniques that …

Conducting Culturally Responsive, Strengths-Based Assessment In Schools, Eileen Cullen

Electronic Theses and Dissertations

Special education assessment has a significant impact on the lives of children with disabilities and their families. However, traditional assessment practices have been critiqued as being deficit-based, overly focused on “labeling” students, and failing to provide a holistic understanding of the student. Assessment models such as strengths-based assessment (SBA) and culturally responsive assessment (CRA), have potential to addresses these critiques and be more appropriate for the growingly diverse school population. Despite this, these models of assessment are under studied and there is a lack of clear guidance for how practitioners should implement them.

In these manuscripts, CRA and SBA are …

A Geospatial And Machine Learning Framework For Forecasting Ground Level Ozone Pollution, William J. Keenan

Electronic Theses and Dissertations

The major detrimental health effects of ground-level ozone (GLO) pollution make it imperative that both policy makers and ordinary citizens have access to high accuracy, high-resolution forecasts of their local area. Recently, advancements in computing power have made it possible to apply artificial intelligence (AI) techniques to a variety of big data modelling problems, including GLO forecasting and estimation. Of these AI methods, deep neural networks (DNN) have demonstrated the highest accuracy due to their ability extract non-linear relationships from high dimensional, noisy data inputs.

This research effort uses novel data sources, namely NOAA’s High Resolution Rapid Refresh (HRRR) meteorology …

Institutional And Structural Evolution Of The U.S. Financial System 1945-2023: The Long-Wave Financial Cycle And The Role Of Thwarting Mechanisms, Shaun K. Brog

Electronic Theses and Dissertations

This thesis develops a theoretical framework that attempts to explain the dynamic interactions that lead to episodes of severe financial instability. Adapting Minsky’s Financial Instability Hypothesis to the specific characteristics of financial intermediaries and building on Ferri and Minsky’s ideas regarding the role of thwarting institutions, I propose that financial fragility is the result of a long-wave cycle in financial relations characterized by significant institutional and structural evolution within the U.S. financial system. This evolution results in a preponderance of financial activity undertaken outside the regulatory umbrella while margins-of-safety are eroded, newly innovated financial assets proliferate, and financial intermediaries become …

There have been various perceptions of how AI affects students and their academic achievement. This capstone project aimed to synthesize multiple current research studies to determine how students and teachers perceived and used artificial intelligence in education (AIED) and how it benefited secondary students' learning potential. As a result of this research, the examined studies revealed that student and teacher perceptions of AI and AIED affected people's willingness to use AI (Chai et al., 2021; Cong-Lem et al., 2024; Mabuan, …

Incremental Quantities Based Permissive Overreaching Transfer Trip Scheme For Protecting Inverter-Based Renewable Resources, Osama Zangoti

Electronic Theses and Dissertations

The power generation landscape evolves, with the increase of inverter-based resources (IBRs) such as solar photovoltaics and wind turbines, providing sustainable and clean energy sources. The shift towards IBRs mitigates climate change, creating considerable challenges to traditional power system protection due to their low fault current. Conventional protection schemes are designed around the internal dynamic of synchronous generators where they can supply an elevated fault current. This thesis explores a protection scheme designed to enhance the security of IBRs. The incremental characteristics of voltage and current coupled with the Permissive Overreaching Transfer Trip scheme (POTT) provide a remarkable ability to …

Changing The Narrative: Student Empowerment In Unequal School Contexts, Stephanie A. Nisle-Mikos

Electronic Theses and Dissertations

Educational experiences affect a wide variety of life outcomes for individuals. The type of education an individual receives influences their occupation, the neighborhood in which they live, and even their risk of mortality (National Research Council, 2013; Sasson, 2016). In particular, the life trajectories of students who attend high-poverty schools are not the same as youth who attend schools with greater resources (National Center for Education Statistics [NCES], 2013; Taylor, 2005). In this dissertation, I provide a brief background on current rates of disproportionality in education and examine how specific theoretical constructs and educational policies may be used to explain …

The Role Of Care Practices, Mutual Aid, And Racial Formation In Black Newcomer Practitioners’ Lived Experience Within Organizations: A Critical Qualitative Inquiry, Annie Zean Dunbar

Electronic Theses and Dissertations

Black newcomers, defined as people who have migrated to the United States regardless of legal status, are one of the fastest-growing immigrant groups. (Morgan-Trostle et al., 2016). Within this population, a small percentage work within the social service sector with other migrants. Using critical qualitative methods, a critical phenomenological methodology and semi-structured interviews, a sample of 17 participants were asked about their experiences of living and working in the U.S. social service sector. The study uses racial formation theory (Omi & Winant, 2014) to conceptualize how participants experienced their racial identity formation and how racism shapes their personal and professional …
