Texas High School Counselors’ And Advisors’ Ccmr Self-Efficacy: An Exploratory Descriptive Study, Amanda R. Jolivet

Electronic Theses and Dissertations

In the last 20 years, there has been a growing emphasis on ensuring high school graduates are prepared for college and career in the 21st century. This is especially true in Texas, a state that has not only instituted college, career, and military readiness (CCMR) policies but has also monetarily incentivized schools and districts for meeting specific CCMR accountability metrics. Although Texas high school counselors and advisors are responsible for ensuring students across the state have access to CCMR information, support, and resources, not much was known about Texas high school counselors/advisors’ self-efficacy as it relates to postsecondary planning or …

Examining Enrollment & Engagement In A Hospital-Based Violence Prevention Intervention Study At A Level 1 Trauma Center, Leigh Frederick

Electronic Theses and Dissertations

BACKGROUND: Violence is a significant healthcare issue that affects the health and well-being of individuals, families, and communities. Violence prevention and intervention programs are a powerful way to stop the revolving door of violent injury in our hospitals and communities. The Health Alliance for Violence Intervention (HAVI), develops and connects violence intervention programs, promotes equity for victims of violence globally, and is dedicated to engaging patients during the window of opportunity when they are recovering in the hospital after a violent injury to reduce the chance of retaliation (related to the injury) and recurrence. A small body of research shows …

Parental View On Hpv Vaccination, Rebecca Elaine Rhodes

Electronic Theses and Dissertations

The human papillomavirus (HPV) is a sexually transmitted infection widely seen in the United States. Millions of Americans are affected by it each year, especially those in their late teens and early 20s. Although most infections will resolve on their own, 1 in 10 will lead to health problems such as cancer. The HPV vaccine can prevent over 90% of associated precancers and cancers. However, uptake of the HPV vaccine and its completion among adolescents are significantly lower than other recommended adolescent immunizations, falling short of the Healthy People 2030 goal of 80% coverage. Understanding parental attitudes, beliefs, and perceptions …

Electronic Theses and Dissertations

Schools that maintain the same principal for 5 or more years report increased student achievement, increased teacher retention, and a positive school culture. The problem is that over 70% of principals will not remain in the same school for 5 years and the average principal turnover rate in the United States is 22%. The purpose of this quantitative study was to explore

principal turnover in Oklahoma from 2011–2024 by answering the following research questions: What is the average principal turnover rate for principals in Oklahoma? Is there a significant difference in elementary and secondary principal turnover rates? Is there a …

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 …

Bridging Design And Perception: Novel Tools And Technologies For Creating Effective Human-Robot Interactions, Benjamin Dossett

Electronic Theses and Dissertations

This thesis explores human perception of robots through the use of novel tools and technologies. First, the impact of Augmented Reality (AR) data presentation on human perception of robots is investigated. A study conducted with the AR human-robot teaming system found that robot performance significantly influenced participants’ perceptions, overshadowing the impact of matching or mismatching robot confidence feedback. Second, the DU Want to Build-A-Bot platform is presented, which enables participatory robot design and opens the door for novel research of how robot design affects human perception. The Build-A-Bot platform enables the collection of diverse robot designs, facilitating machine learning analysis …

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 …

Collective Case Study Career Critique Of Social Entrepreneurs Who Are Gifted Adults, Joi Lin

Electronic Theses and Dissertations

This dissertation describes a qualitative research study that grows our understanding of the career development experiences, supports, and barriers of social entrepreneurs who are gifted adults (SEGA) so that we may nurture the career development of future SEGA. Research questions for this study probed the career development experiences, supports, and barriers of SEGA and the shared social value they create. The conceptual frameworks for this study are the ecological model for human development (Bronfenbrenner, 1979); the theory of positive disintegration (Dąbrowski, 1964/2016); social cognitive career theory (SCCT; Lent et al., 1994); the perceived instructional arc (Uhrmacher et al., 2017); and …

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 …

Radical Hospitality: Height And Excess Of The Other And The New Host Self, Diako Alikhani

Electronic Theses and Dissertations

Drawing on Emmanuel Levinas’ ethical framework and its emphasis on the “height and excess” of “the Other,” this thesis explores and develops a sense of “radical hospitality” in Levinas and across Judaism, Christianity, and Islam. In particular, the thesis explores how encounter with the Other is not only marked by an overwhelming excess, but one which transforms the subject into what I call a “New Host Self:” Where the self is the host who greets the stranger with hospitality, it is ultimately the stranger—the refugee, the migrant—who transforms the host into someone new. Here, the host ultimately receives a gift …

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 …

Minimum Wage: Theoretical And Empirical Debates, Ghofran Alrebh

Electronic Theses and Dissertations

This thesis aims to explore the evolution of research methodologies in the minimum wage debate, focusing on the contrasting perspectives of the neoclassical and institutional models. By examining the changes in research methodologies employed by economists from these two schools, this study seeks to shed the light on the shifting paradigms and the impact of these changes on our understanding of minimum wage policies and their implications. This highlights the limitations of relying on one economic school of thought in understanding socio-economic phenomena complexations and policy decisions. As well as it creates the necessity to critical evaluation of the method …

It aims to uncover how school leadership decisions, practices, and policies address the diverse needs of newcomer students. Challenges faced by newcomers, including economic and social needs, cultural adjustments, and potential feelings of alienation despite academic success, are explored. The tension between preserving home culture and adapting to a new one adds complexity to newcomer students’ identity formation.

This study examines the practices of a newcomer school leader who addresses the diverse needs of vulnerable newcomer students. With schools being …

Combinatorial Problems On The Integers: Colorings, Games, And Permutations, Collier Gaiser

Electronic Theses and Dissertations

This dissertation consists of several combinatorial problems on the integers. These problems fit inside the areas of extremal combinatorics and enumerative combinatorics.

We first study monochromatic solutions to equations when integers are colored with finitely many colors in Chapter 2. By looking at subsets of {1, 2, . . . , n} whose least common multiple is small, we improved a result of Brown and Rödl on the smallest integer n such that every 2-coloring of {1, 2, . . . , n} has a monochromatic solution to equations with unit fractions. Using a recent result of Boza, …

Evidence Of Climatic Influence On Subsistence Strategies At Sage Hen Springs, Nevada, Andrew Rogers

Electronic Theses and Dissertations

Models of settlement patterns in the northwest Great Basin describe a decrease in residential mobility, intensified use of upland spring ecozones, and an increase in diet breadth during the Middle and Late Archaic. Here, I present data collected from the Sage Hen Springs site in northwestern Nevada during a Phase II testing project conducted by the BLM and an analysis of these data focusing on patterns of subsistence and mobility strategies throughout the Archaic. Results of this analysis support existing models of lifeways in the northwest Great Basin at the small scale and point to climatic factors as influences on …

Building Blocks For W-Algebras Of Classical Types, Vladimir Kovalchuk

Electronic Theses and Dissertations

The universal 2-parameter vertex algebra W_∞ of type W(2, 3, 4; . . . ) serves as a classifying object for vertex algebras of type W(2, 3, . . . ,N) for some N in the sense that under mild hypothesis, all such vertex algebras arise as quotients of W_∞. There is an ℕ X ℕ family of such 1-parameter vertex algebras known as Y-algebras. They were introduced by Gaiotto and Rapčák are expected to be building blocks for all W-algebras in type A, i.e, every W-(super) algebra in …

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 …

Capturing Latent Abilities And Latent Capacities Of Professional Golfers Using Nonlinear Mixed Effects Growth Modeling, Mac Wetherbee

Electronic Theses and Dissertations

This study demonstrates an effective and innovative approach to measuring the latent athletic abilities and capacities of professional golfers. I used nonlinear mixed effects growth modeling (e.g., Dynamic Measurement Modeling) to measure professional golfers’ ability levels and capacities for improvement. I accomplished this using a two-stage modeling approach. First, a crossed linear mixed effects model estimated each player’s ability level in each year. In the second stage, I used the results from the first stage to estimate several candidate nonlinear growth trajectories for players’ abilities over time. The quadratic growth trajectory was the best-fitting of these trajectories and was used …

Picturesque Portraiture: The Composition Of Reality In Hawthorne, Melville, And James, Angela Michael Gattuso Densmore

Electronic Theses and Dissertations

Throughout the nineteenth century, American artists were tangled in debates regarding the representation of reality. The Hudson River School of picturesque landscape painters tackled this dilemma with a compromise formula which used the real objects of nature to create ideal scenes. This dissertation applies the same picturesque formula to select examples of literary portraiture, studied under the concept of “picturesque portraiture.” Whereas the Hudson River compromise resulted in an ideal perception of reality, however, the picturesque portraits composed by nineteenth-century authors Nathaniel Hawthorne, Herman Melville, and Henry James attempt to invoke a non-idealized “actual” reality of the portrait subject’s person …

Neuroinflammation In Alzheimer’S Disease Mouse Brain Following Repetitive Mild Traumatic Brain Injury, Lujain Almuhanna

Electronic Theses and Dissertations

Traumatic brain injuries (TBIs) are a common form of head injury, with mild TBIs (mTBIs) making up 75-90% of the TBI severity scale. It’s been suggested that repetitive mild TBIs (rmTBIs) may enhance effects of Alzheimer’s Disease (AD). With dementia linking TBI and AD together, we investigated the memory hub of the brain - the hippocampus. Astrocytes and microglia are two glial cells that respond to neuroinflammation and therefore imaged in hippocampal regions of the 3xTg-AD mouse brain. We hypothesized that AD brain pathology (i.e., neuroinflammation) would be accelerated in 3xTg-AD mice following rmTBIs early in life. Analyses revealed that …

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 …

Digital Dialogue: Emancipatory Dialogical Practices In Virtual Collaborative Problem-Based Learning, Chelsie Ruge

Electronic Theses and Dissertations

Societal shifts increasingly demand that people work across social and geographic borders, often virtually, to solve complex problems in the areas of education, environment, healthcare, poverty, technology innovation and ethics, and more. This collaboration requires critical and emancipatory dialogue and problem-solving.

This qualitative multiple case study examined two online professional studies graduate-level courses that employed collaborative problem-based learning to engage with social-justice related themes, one that explored inclusive educational practices, and one that explored the negotiation of global environmental treaties. 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

Electronic Theses and Dissertations

Culturally Responsive Practices (CRP) are a focal point for many districts across the country. The emphasis of CRP is on how the institution enacts policies and practices for the benefit of the students they serve. This study views CRP from a different lens. The focus of this study is to 1.) center the voice of Black teachers and 2.) explore culturally responsive practices for the support and edification of the teacher from their coach/supervisor. The eight Black teacher participants and their instructional coaches engaged in interviews discussing current coaching models and the dynamics of their coaching relationships.

The relevant findings …

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 …

Exploring The Experiences Of Hiv Positive Pregnant Women On Prevention Of Vertical Transmission Of Hiv/Aids In Rural Malawi, Gertrude Finyiza

Electronic Theses and Dissertations

Mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) continues to be the primary conduct that HIV is transmitted to children worldwide. The problem of HIV/acquired immunodeficiency syndrome (AIDS) is having a great impact on the world's children. The prevalence of HIV/AIDS in Malawi continues to be a serious public health issue, especially for expectant mothers. The health outcomes of mothers and children remain significantly threatened by vertical HIV transmission, even with improvements in preventive and treatment efforts. The purpose of this thesis was to explore the experiences of HIV-positive pregnant women in Malawi. I conducted semi structured interviews with thirteen …

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 …

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 …
