Co-Rumination, Psychological Inflexibility, And Internalizing Symptoms In Adolescence, John Parigger

Electronic Theses and Dissertations

Two risk factors for anxiety and depression in adolescence were examined: co-rumination, which occurs when friends excessively talk about problems; and psychological inflexibility, which occurs when one avoids negative feelings and fails to act on values. I hypothesized that psychological inflexibility would exacerbate the effect of co-rumination on adolescent anxiety and depression. Participants were 167 adolescents (Mage = 14.60 years, SD = 1.3; 65.7% cisgender males) who completed standard measures as part of an online survey. Results indicated no moderation effect, but there were main effects of co-rumination and psychological inflexibility on depression symptoms. Co-rumination may relate to …

Spectral Sensitivity Of Circadian Entrainment In Araneoid And Non-Araneoid Spiders, Craig Campbell

Electronic Theses and Dissertations

Artificial lighting at night is a growing worldwide phenomenon that can negatively impact flora and fauna in the surrounding area. With new technology, there is now opportunity for change: newer LEDs can emit specific wavelengths of light that may be less ecologically damaging. In this study, we aim to describe the circadian spectral sensitivity of two phylogenetically distant urban spider species with similar life histories, the Araneoid Parasteatoda tepidariorum and non-Araneoid Pholcus manueli, to determine differences between them. We exposed these spiders to progressively dimmer levels of white, blue, green, or red light. Despite evidence that spiders lack visual …

Shame, Guilt, And Behavioral Responses To Conflict In Organizational Life: A Correlational Study, Lori Anne Shaw

Harry Potter And The Immersive Space: A Rhetorical Analysis Of The Wizarding World Of Harry Potter, Kendra Bolin

Electronic Theses and Dissertations

The ability of humans to share stories has changed over time. From myths shared around a campfire to the introduction of cinema, we can now tell massive, immersive stories on an epic scale. One example of this is the storytelling present in theme parks. Present-day theme parks are continuously growing and expanding each year both in size and attendance. The continued success of these theme parks and the rhetorical influences of their audiences is a cultural phenomenon that deserves rhetorical scrutiny. My analysis looks at how one theme park, the Wizarding World of Harry Potter in Orlando, Florida, immerses guests …

Trust, Transparency, And Transport: The Impact Of Privacy Protection On The Acceptance Of Last-Mile Drone Delivery, Jurgen Heinz Famula

Electronic Theses and Dissertations

A common set of problems commercial delivery companies face is finding ways to increase the efficiency and reliability of the “last mile” of a package’s journey, all while reducing operating costs. This need for efficiency has driven many companies to explore using unmanned aerial vehicles (UAVs), or drones, to get packages to their final destination. Although UAVs have great potential to help increase efficiency in commercial package delivery, this comes at a potential cost to the privacy of people who intersect the flight paths of these unmanned vehicles. This thesis explores the effect of a mobile phone application for commercial …

The Role Of Edc3 In Drosophila Melanogaster Neuronal Development, Keelan Zius

Electronic Theses and Dissertations

Enhancer of mRNA-decay 3 (Edc3) is a component of multiple decapping complexes that regulates the transcriptome by targeting a subset of transcripts for decapping for 5’-to-3’ messenger RNA (mRNA) decay. A missense mutation in the conserved Lsm domain of Edc3 has been reported in two siblings presenting with mild, non-syndromic intellectual disability (ID), however, the role of Edc3 is neuronal development has never been evaluated. Here, we use the Drosophila melanogaster model system to investigate the effects of Edc3 disruption on neuronal development. We found Edc3 reduction leads to significant hyperplasia at the larval neuromuscular junction (NMJ), providing the first …

Cannabis Exposure During Pregnancy And Neural Mechanisms Of Parenting: Assessing Neural Responses To Infant Cues And Parenting Outcomes, Shannon Powers

Electronic Theses and Dissertations

As legalization of cannabis and cannabinoids spreads in the United States, access and use of cannabis during the prenatal period has increased. There is limited knowledge on the effects of prenatal cannabis use on the parental brain. One way to identify potential effects of cannabis on parenting is through studying parenting brain functions and behavior. Cannabis use disorder (CUD) has been shown to be associated with lower positive parenting and lower sensitivity to infants, but it is unclear by what mechanisms. The following two studies address this gap in knowledge by examining the association between cannabis use during the prenatal …

Self-Efficacy And Racial Identity For Undergraduate Music Majors, Rachel E. Lim

Electronic Theses and Dissertations

Students’ identities can impact their self-efficacy, or their confidence in their ability to succeed in producing a desired outcome (Bandura, 1997; Klassen, 2004a; Klassen 2004b; Oettingen, 1995; Usher & Pajares, 2008); however, little peer-reviewed research explores the relationship between racial identity and self-efficacy for undergraduate music majors. In the United States, undergraduate music students of color often navigate educational experiences where they do not find their identities represented in the curricula (Ewell, 2020), their faculty (Higher Education Arts Data Services [HEADS], 2020), or their fellow students (HEADS, 2020).

This convergent mixed methods study utilized the theoretical framework of critical race …

Honoring Indigenous Worldview: Cultural (Un)Responsiveness In Gifted Education, Vicki Boley

Electronic Theses and Dissertations

Many working understandings of giftedness exist within dominating Western frameworks, gatekeeping gifted education from students who do not “fit” inside such frameworks (Owens et al., 2018; Rinn et al., 2020; Sternberg et al., 2021). As a result, K- 12 Native American, Alaska Native, and Native Hawaiian students are underrepresented in gifted education programs (Sternberg et al., 2021) and overrepresented in special education programs (NCLD, 2023). When considering Indigenous students in particular, Western orientations surrounding giftedness perpetuate assimilation, dominance, and continued colonization (Battiste, 2013; Dunbar-Ortiz, 2014; Gentry & Gray, 2021a). Leveraging Positionality and The Pedagogy of Listening as conceptual frameworks, this …

Reconciling Moral Dissonance: A Framework For Re-Integrating Moral Orientation With Life Agency During Warfighters’ Struggles With Military Moral Injury, Jeffrey L. Zust

Electronic Theses and Dissertations

This dissertation uses case studies to critically examine the Three Mirror Model (TMM) as a framework for understanding the formation and healing of Military Moral Injury (MMI). I adapt the work of Stephen Brookfield and Neal Krause to evaluate using the TMM as a methodology for dealing with the complex issues of MMI within a military deployment cycle (training, warfighting, and healing) (Brookfield 2012, 2017; Krause 2022). Specifically, I use theorists, researchers, healers, and warfighters as key stakeholders to identify and critically examine the intersections of disciplines and the subsets of models where warfighters’ moral orientations and moral agency form …

Bridging The Geometric And Quantum Information Of Structured Light, Andrew Alexander Voitiv

Electronic Theses and Dissertations

In this Dissertation, we review the several advances we have developed for preparing and measuring the geometric and quantum information of structured light. The geometric phase acts as a memory of transformations undertaken by physical processes; quantum entanglement underpins quantum information science which explores the theoretical and technological applications of nonclassical correlations. Beginning with classical light, we demonstrate novel experiments and measurements of geometric phase that are enabled by spatially structuring laser beams. We then extend those concepts to complement the richer possibilities within quantum optics. Our work covers new abilities in tailoring and measuring the phase content of spatially-structured …

The purpose of this study was to investigate how students engaged in emancipatory dialogical practices and determine the factors that …

Sources Of Sexual And Romantic Education: Associations With Sexual Minority Men’S Sexual Experiences And Romantic Relationship Quality, Charlie Huntington

Electronic Theses and Dissertations

Individuals with sexual minority identities experience a variety of poorer mental and physical health outcomes, including those related to sexual and romantic quality, relative to heterosexual individuals (Beaulieu et al., 2017; CDC, 2021). These poorer romantic, sexual, and psychological outcomes may be attributable in part to lacking access to affirmative and relevant modeling of sexual minority experiences, such as through sex education (Gillespie et al., 2022; Keiser et al., 2019). This study aimed to understand how sexual minority men learn – in ways potentially both helpful and unhelpful – about romantic relationships and sexual activity, and how these experiences are …

Culturally Responsive Coaching: Supervision With A Cultural Lens, Jouanna Crossland-Wells

The Elephant In The Baithak: Tabla And Audio Technological Discourse, Tyler Thom

Electronic Theses and Dissertations

This thesis discusses how power, status, and performance practices play out between performers of tabla (North Indian hand drums) and audio engineers. To do so, I analyze engineer, performer, and music critic discourse surrounding tabla performances and technology to place it within a broader scholarly debate regarding recording technology, cultural/technological capital, technological determinism, and agency. I extend Christopher Scales’s (2012) concept of “recording culture” to “live sound culture,” or the behaviors, power struggles, and labor surrounding tabla mic’ing and amplification. I argue that audio technology separates the artist’s sound into several domains of control (stage, hall, recording, playback), each controlled …

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 …

Navigating University Of Denver As A Latinx Male-Identifying Undergraduate Student, Quisi Rodriguez-Oregel

Electronic Theses and Dissertations

Students of color continuously persist at a lower rate than their white counterparts in higher education. Particularly for Latinx males, the number is lower than Latinx women. Universities have incorporated Diversity, Equity, and Inclusion (DEI) strategies to focus on their diverse student population and address issues of race, ethnicity, class, and gender. Despite these efforts, low retention rates for Latinx males persist. This study explores how Latinx male undergraduate students navigate a predominantly white institution as well as explore some of the challenges of DEI efforts at that institution. I conducted participant observations at the University of Denver (DU) and …

Leadership In Extreme Contexts: An Emerging Typology, Ashley Williams

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 …
