Rhetorical Genealogy And The Ethics Of Eugenics, David Mark Thomas

Electronic Theses and Dissertations

This dissertation strives to critique contemporary rhetoric on eugenics. In recent years, scientists succeeded in mapping the human genome and subsequently developed new gene editing technologies. To situate current ethical discourses about eugenics, I trace histories of these discourses at several scales of society – from the macroscopic level of the body politic to the meso level where modes of assessment have been deployed purportedly to accurately evaluate human characteristics to the microscopic level of the gene. I employ Foucauldian genealogy to highlight how, despite marked differences over time in specific eugenic discourses and practices exist, the underlying rhetoric has …

Behind The Exhibit: Exploring The Processes Of Indigenous Rights Representation At The Canadian Museum For Human Rights, Madison Caroline Dillard

Electronic Theses and Dissertations

Focusing on the representation of Indigenous human rights at the Canadian Museum for Human Rights (CMHR) in Winnipeg, Manitoba, this study examines how museums can represent, educate, and advocate for Indigenous human rights. The study is based on ethnographic fieldwork carried out at the museum in July 2019 and the literature on anthropology and human rights, decolonizing museum practices, and museums as spaces for human rights dialogue. The study shows how museums can change their history of racist and inaccurate representation of Indigenous people. Through extensive and “deep collaboration” between Indigenous partners and museum staff, Indigenous culture, history, and rights …

Certification-Driven Testing Of Safety-Critical Systems, Aiman S. Gannous

Electronic Theses and Dissertations

Safety-critical systems are those systems that when they fail they could cause loss of life or significant physical damages. Since software now is an essential component of these types of systems, failures caused by software faults could come from flaws in the software development life-cycle. As a result, challenges unfold in two directions. First, in verifying that the software will not put the system in an unsafe state, and identifying external failures and mitigate them properly. Second, in providing sufficient evidence for an efficient safety certification process. In this study, we propose an approach for testing safety-critical systems called Model-Combinatorial …

Cultural Wealth Of First-Generation College Students And Its Effects On Well-Being, Persistence, And Major Satisfaction, Eve M. F. Sussman

Electronic Theses and Dissertations

Although understanding of FGCS’s success in higher education has been enhanced over the last decade, less is known about their career and educational development, and how their strengths and assets promote college success. The purpose of this study was to explore the relations between first-generation college student (FGCS, [N= 130]) cultural wealth variables, work volition, and outcomes (i.e., academic major satisfaction, persistence, and well-being) using the Critical Cultural Wealth Model (CCWM; Garriott, 2020). Results of regression analyses partially supported CCWM propositions. Significant, positive correlations were observed between resilience and work volition, academic major satisfaction, and well-being. Significant, positive …

An Economic Analysis Of Cyber Warfare Governance Models, Kevin M. Kelleher

Electronic Theses and Dissertations

Allusions to death delivered by bits and bytes have been in vogue since the Reagan administration. Yet, as the internet and its connected devices have since proliferated, cyber violence remains far more fiction than fact. Nevertheless, prominent U.S. officials have all but assured the eventuality of a devastating attack. In anticipation, political, legal, and industry experts are now seeking to codify and inculcate international norms to govern acts of war prosecuted via cyberspace. Two of the most prominent governance models to emerge are the Tallinn Manual and Microsoft’s Digital Geneva Convention. The driving thesis of this research argues that within …

Living The Dream: Building Self-Determination To Improve Postsecondary Outcomes, Pete Gladstone

Electronic Theses and Dissertations

Despite recent federal legislation outlined in the Individuals with Disabilities Education Act (IDEA) reauthorization of 2004 that mandates effective postsecondary transition planning for all students with Individualized Education Programs (IEPs), students with intellectual disability (ID) continue to experience inequitable postsecondary outcomes, particularly in the areas of postsecondary education (PSE), employment, and independent living (Lipscomb et al., 2017). It has been established that one effective method for improving those outcomes is to develop students’ self-determination abilities, and there is near unanimous agreement within the education community that doing so should be a primary objective during the transition process (Izzo & Lamb, …

Retaining Gifted Individuals For The Sustainability Of Rural Communities, Jessie B. Matthews

The narrative methodology revealed the perceptions of remote rural community members through single, face-to-face interviews to understand the challenges and opportunities young gifted individuals encounter. Through community member interviews, participants echoed sentiments indicating supports, barriers, and the power of place play a significant role in gifted individuals’ desire to remain in their local community. The findings suggested through celebrating place, engagement in the local community, and encouragement to solve local problems, gifted individuals will engage in …

Disrupting Disparity: A Critical Race Transformative Mixed Methods Examination Of School Discipline, Ceema Samimi

Electronic Theses and Dissertations

Racial disparities in school discipline are well-established in the United States’ public-school system. These disparities contribute to a phenomenon known as the school-to-prison pipeline. This phenomenon is a metaphor for the mechanisms that push students, especially students of color, out of school and into the justice system. While research has examined the causes and impacts racial disproportionality in discipline, no studies have focused on schools with no disparities. This study used Critical Race Transformative Mixed Methods to examine school-level quantitative data while employing phenomenological methods to interviews with 12 teachers using critical race theory as a lens. Findings revealed that …

A Spectropolarimetric Study Of Southern Wr + O Binaries, Andrew G. Fullard

Electronic Theses and Dissertations

The classical Wolf-Rayet (WR) state is the evolved stage of a massive star, post main-sequence. They are characterized by their strong emission line spectra and stellar winds that are often more than 10 times denser than that of their progenitor O-type stars, which have mass loss rates of 10^-6 M_Θyr^-1. The evolution of WR stars and their connection to specific types of supernovae (SNe) is an open question. Current theory suggests that rapidly rotating massive stars may be the progenitors of SNe that produce long-duration gamma-ray bursts. The interaction between WR stars and their companion …

Antitrust In Times Of Information Technology: An Analysis Of Big Tech Monopoly Cases, Shamayeta Rahman

Electronic Theses and Dissertations

The information technology industry is one of the most rapidly growing yet concentrated markets existing today. Big Tech monopolies and their increasingly anticompetitive behavior posits risks for competition, technological innovation and consumer welfare. This ranges from price discrimination, limiting consumer choices to the unethical use of data. The particular nature of information technology, with its network effects and negligible marginal costs, incentivizes and facilitates predatory market practices making antitrust analysis in this industry extremely complex. Certain schools of antitrust thought are more sensitive (namely the post-Chicago school) to these implications than others, though antitrust application is still lacking in both …

“Dialogical Offense:” A Postcolonial Womanist Deconstruction Of The Colonial Experience Of African American Women Through U.S. Institutional Apparatus Known As Criminal Justice Policy, April Michelle Woodson

Electronic Theses and Dissertations

The Black female experience in the United States is a colonized existence. This project’s analysis is specific to the North American U.S. geographic space and is not a diasporic project. Black women suffered from the greatest increase in the percentage of inmates incarcerated for drug offenses in the 1980’s and 1990’s which is the period of criminal justice policy formation and implementation on which this project is focused.

This project is uniquely situated in the overlap between womanist ethics and postcolonial feminist imagination and extends scholarship in both discourses by showing that there is an interwoven line between the colonial-to-contemporary …

Social Support Among Undergraduate Students: Measure Development And Validation, Heather M. Blizzard

Electronic Theses and Dissertations

Being born into circumstances of low-income, having a racial minority status, and/or non-college educated families dwindle the opportunities for many students to obtain a college degree (Cox, 2016; Engle & Tinto, 2008; Jenkins et al., 2013). While many institutions of higher education have diligently worked to develop programs geared towards attending the educational inequalities among diverse student populations, there is still a great need for programs centered on the inequalities surrounding social support (Cox, 2016; Ward et al., 2012; Soria & Stebleton, 2012).

The purpose of this study was to develop and assess a measure to examine perceived social support …

Manifestations: Displays Of Internal Beliefs And Perspectives, Manuel Ferreira

Electronic Theses and Dissertations

This thesis aims at better understanding and sharing the internal beliefs, influences, and insights of specific Field Museum staff in regard to exhibitions and the future of the Field Museum. It is people that make up museums and create exhibitions, and their beliefs not only influence and guide them, but also their institution and what they develop. Grounded in museum anthropology, and framed by new and critical museology, entanglement, contact zones, museum as method, and a queer mezclando (mixing) perspective, this research employs museum ethnography as a way of exploring relations and meanings among museum staff, beliefs, and manifestations. In …

Framing Representation: An Ethnographic Exploration Of Visual Sovereignty And Contemporary Native American Art, Laura A. Hughes

Electronic Theses and Dissertations

The nature of this research is to explore the idea of visual sovereignty within contemporary Native American art, and how this concept engages with practices of decolonization. Through conducting semi-structured interviews with five artists who selfidentify as Native American, I explore how the artists engage with this concept, what visual narratives their artwork presents, and how their works function as acts of decolonization. I connect their narratives to a broader conversation of critical museology and museum anthropology within museum spaces including how to reconsider the art/artifact divide, how to frame Indigenous arts reception through Indigenous aesthetics, and how their narratives …

Age Bias In Clinical Judgment: Moderating Effects Of Ageism And Multiculturalism, Kristin Pyne

Electronic Theses and Dissertations

The proportion of older adults in the United States is growing rapidly (U.S. Census Bureau, 2014) and mental health concerns in older adults are expected to increase rapidly (Choi, DiNitto & Marti, 2015). Despite increasing caseloads of older adults, few practicing psychologists have received specific training or specialization in geropsychology (American Psychological Association, 2016). Simultaneously, a growing body of literature demonstrates differential treatment of older adults in psychotherapy (Kessler & Bowen, 2015, Kessler & Schneider, 2016, Mejia et al., 2018). The present study aimed to examine the prevalence of clinical bias toward older adults among clinical trainees and to explore …

As renewable energy sources, such as photovoltaic (PV) cells and wind turbines, are rapidly implemented in DC microgrids, energy storage systems play an increasingly significant role in ensuring uninterrupted power supply and in supporting the reliability and stability of microgrid operations. Power electronics, especially bidirectional DC–DC converters, are essential parts in distributed energy storage and alternative energy systems because of their grid synchronization, DC power management, and bidirectional power flow capabilities. While there is increasing demand for more efficient, compact, and reliable power converters in numerous applications, most existing power converters are hindered by traditional silicon (Si) based semiconductors, which …

The Emerging Metamodern Sensibility In Narrative: A Case Study Of Things Left Forgotten And The Dai Gyakuten Saiban Games, Gina Barbieri

Electronic Theses and Dissertations

This thesis proposes a metamodern shift in recent narrative trends, which incorporate modernist and postmodernist techniques for narrative. This includes narrative shifts which utilize postmodern devices such as irony and satire for seemingly modern ends such as hope and progress. This thesis posits that this shift can be understood through an analysis of emergent media, and considers the intertextual nature of fanfiction narratives emerging from games through a case study of Things Left Forgotten, a fanfiction written by Archive of Our Own user LookerDeWitt and based upon the two Dai Gyakuten Saiban games, spinoffs of the Ace Attorney series …

Urban Green Space: Mitigator Or Multiplier Of Inequality In The Denver Metropolitan Area?, Joshua Charles Baldwin

Electronic Theses and Dissertations

Studies have shown that communities of color and low-income populations are likely to live in neighborhoods that lack access to quality green spaces, unable to directly benefit from the environmental, recreational, and cultural services they provide. The goal of this research was to determine if the green space inequality patterns seen globally and nationally exist in the Denver Metropolitan Area. Using an existing green space dataset, ecosystem services fieldwork, GIS digitizing, and bivariate correlation analysis I uncovered numerous green space inequalities based on proximity, acreage, and quality. Key findings included 1) Lakewood’s Hispanic and less-educated populations have relatively little access …

Impacted Youth: Why School Psychologists Need To Consider Diverse Approaches Of Support, L. Morgan Beidleman

Electronic Theses and Dissertations

This paper examines trends among youth who are highly impacted by multiple adverse experiences. It outlines potential patterns of risk and protective factors often experienced by this population and encourages school psychologists to recognize, consider, and advocate for the needs of these youth. It goes on to describe and interpret the cultural practices of Leadership Coffeehouse, a Denver-based social enterprise that seeks to support disconnected youth through professional development and hands-on learning. Finally, because of the unique training school psychologists receive, considerations for expanding the role into non-traditional educational settings are proposed.

Ayahuasca’S Religious Diaspora In The Wake Of The Doctrine Of Discovery, Roger K. Green

Electronic Theses and Dissertations

‘Ayahuasca’ is a plant mixture with a variety of recipes and localized names native to South America. Often, the woody ayahuasca vine (Banisteriopsis caapi) is combined with chacruna leaf (Psychotria viridis) in a tea, inducing psychedelic effects among its users. While social usage varies among Indigenous Peoples of South America, during the twentieth century new religious movements in Brazil began employing the mixture as religious sacrament. Additionally, various centers for ayahuasca “healing” have emerged both inside and outside of the Amazon Rainforest, frequently with the aim of helping people addicted to other substances. As interest grew, …

An Examination Of Relational Health, Belonging, And Self-Compassion In Chinese International Students, Elizabeth A. Harris Shaffner

Electronic Theses and Dissertations

Chinese international students (CISs), the largest segment of international students coming to the US to study at institutions of higher education (IIE, 2016), are reported to experience more acculturative stress than other international students because of the vast differences in social and cultural norms between the United States and China (Li & Glasser, 2005; Yeh & Inose, 2003). The present study used Relational-Cultural Theory (RCT) as the framework to explore the ways undergraduate CISs struggle and thrive in the face of acculturative stress and to understand how positive and negative outcomes are associated with their relational health, sense of campus …

Assessing Robustness Of The Rasch Mixture Model To Detect Differential Item Functioning - A Monte Carlo Simulation Study, Jinjin Huang

Electronic Theses and Dissertations

Measurement invariance is crucial for an effective and valid measure of a construct. Invariance holds when the latent trait varies consistently across subgroups; in other words, the mean differences among subgroups are only due to true latent ability differences. Differential item functioning (DIF) occurs when measurement invariance is violated. There are two kinds of traditional tools for DIF detection: non-parametric methods and parametric methods. Mantel Haenszel (MH), SIBTEST, and standardization are examples of non-parametric DIF detection methods. The majority of parametric DIF detection methods are item response theory (IRT) based. Both non-parametric methods and parametric methods compare differences among subgroups …

Living Words; Dying Flesh: The Truth And Testimonies Of Desdemona In Othello And Pompilia In The Ring And The Book, Martha Clare Brinkman

Electronic Theses and Dissertations

This thesis explores the ways in which Desdemona in William Shakespeare’s Othello (1603/4) and Pompilia in Robert Browning’s The Ring and the Book (1868) exemplify female characters whose testimonies highlight their souls’ salvation and demonstrate that they ultimately transcend their domestic roles. This thesis engages historical scholars who discuss the tensions between the Roman Catholic and Anglican churches and the state in early modern and Victorian England, and literary scholars who focus on Desdemona and Pompilia as either submissive or possessing agency. This thesis includes the work of developmental psychologist, Carol Gilligan, to show how Desdemona and Pompilia emphasize care …

School Facet Through Surrounding Factors: A Geospatial Analysis Of Community Social Capital Impacting Elementary Schools, Sajjid Budhwani

Electronic Theses and Dissertations

School performance rating is an important factor which not only provides a quick snapshot of how the students are performing on various measurement indicators but also decides a school’s future course of actions, strategies, resources, and its existence. Despite its significant importance, the school performance framework does not consider where the schools are geographically located and the surrounding factors within which they operate. The researcher of this study presented a landscape of the surrounding factors and its impact on the elementary schools within Denver Public Schools district. In this study, the surrounding factors are geospatially analyzed to determine the extent …

Socioeconomic Disadvantage And Brain Structure In Adulthood, Alexander J. Dufford

Electronic Theses and Dissertations

Socioeconomic disadvantage in childhood has been associated with difficulties in physical and mental health later in life. A potential pathway underlying this association is through variations in brain development. While associations between concurrent socioeconomic disadvantage and brain structural development have been established, it is unclear if there are prospective associations between childhood disadvantage and brain structure later in life (adulthood). The following studies address these gaps in the knowledge by examining the prospective association between childhood socioeconomic status and brain structure in adulthood. Study One examines the association between average family income across childhood and brain structural morphometry in adulthood. …

Rab39 And Klp98a Are Required For Furrow Formation During Early Drosophila Embryogenesis, Megan R. Millage

Electronic Theses and Dissertations

The formation of a plasma membrane furrow is an essential process during development. Furrow formation is necessary for successful cell division and cytokinesis in addition to the ability to create multicellular tissues. Here, I will explore the role of the Golgi-associated Rab protein Rab39 in furrow formation during early Drosophila embryogenesis. Rab39 is one of eight Rab proteins that has been shown to localize to discrete puncta by live imaging in early Drosophila embryos, but its function and pathway have not been well characterized. In this thesis will I show that Rab39 forms dynamic, tubular structures that colocalize with trans-Golgi …
