“This Rigid Curricular Way”: Evaluating Expectations In Collegiate Music Education, Sophie Ailsa Lewis

Electronic Theses and Dissertations

Conversations surrounding curricular reform are abound in music education today. Much of the literature on this topic explores how professors can adapt their teaching practices to the presumed needs of students in the classroom, but student voices are infrequently centered in these discussions.

This thesis examines the study of music in the collegiate setting from the student perspective. Using a survey which I designed and interviews that I conducted, I examine the disconnect between student values and those of the institutions they attend. I then put these student perspectives in conversation with existing literature.

I discovered that student experiences revolve …

Outdoor Early Intervention Services: Current Practices And Future Directions, Tiffany Lee

Electronic Theses and Dissertations

Outdoor play is a crucial in supporting child development, resiliency, social skills, creative thinking, adaptability, family growth, and family engagement. Unfortunately, children are spending less time outside because of technology, parent fears, and other factors. Parents who have a child with a disability have even more challenges when it comes to playing outside. Thus, children with disabilities are spending even less time in outdoor environments. Early Intervention (EI) is a program that is designed for infants and toddlers between the ages of zero to three that have developmental delays and/or disabilities. EI uses a family-center approach in natural environments to …

A Labor Of Love: Extensive Exploitation Of Contract Music Workers, Malia Odekirk

Electronic Theses and Dissertations

Workers across the United States are reckoning with unfair labor conditions by unionizing and speaking out. Systemic undervaluing of many workers has created a climate of fear, hidden agendas, and pervasive labor misconduct. The pageantry/marching arts are no exception. As a cultural insider, I conducted interviews, had many informal conversations, and ran a large survey that uncovered how the marching arts exploit instructors extensively despite their experience, education, and efforts. A systematic proclivity toward late payments, abused contracts, egregiously low compensation, and free labor begs the question: how can programs continually mistreat instructors this way? I explore this question through …

The findings of this study indicated that tech-savvy principals were not stuck in the structural rut that most principals found themselves in during the COVID-19 crisis. Four main themes emerged from the data. The first theme addressed how recognized tech-savvy principals demonstrated decisive decision …

Evaluating The Impact Of Individual And Couple Relationship Education On Postpartum Depression, Maggie O’Reilly Treter

Electronic Theses and Dissertations

This dissertation evaluated the impact of relationship education on postpartum depression using data from two randomized controlled trials of relationship education for individuals and couples who were pregnant or recently had a baby. Paper 1 focused on a well-established relationship education program for low-income couples in Oklahoma City, Family Expectations. Key findings from Paper 1 demonstrated that being randomized to Family Expectations was associated with lower odds of experiencing depression in the first 12 months after having a baby among both mothers and fathers, though this effect was only marginally significant, and that the program had the strongest impact among …

Restorative Justice & A Dean Of Students: An Auto-Criticism Of The Role Of Care In School Discipline In A Poverty Impacted Public High School, Alicia D. Vasquez

Electronic Theses and Dissertations

This qualitative study is an auto-criticism, an approach that allows researchers to study themselves. This emergent methodology is derived from educational criticism and connoisseurship, which fits under the broader category of arts-based research. School discipline is a programmatic component of any secondary school’s educational framework and directly effects student engagement and academic achievement. An analysis of the dean role in relation to school discipline is central to this study. The main research question is what are the lived experiences of a dean who incorporates restorative justice practices in a poverty impacted public high school?

The author spent two years as …

Pulmonary Valve Replacement, Mina Shafiei

Electronic Theses and Dissertations

Currently, transcatheter pulmonary valve replacement (TPVR) is a well-established alternative for surgical pulmonary valve replacement (SPVR) to treat pulmonary valve disorders in patients with prior congenital heart surgery. Edwards Sapien 3 valve is a bioprosthesis originally designed for the aortic position but has been used off-label in native right ventricular outflow tract (RVOT). It is currently under clinical trial to get food and drug administration (FDA) approval.

This study is a comparison of the performance of Sapien 3 with surgical bioprosthetics. The in vitro tests result showed Sapien 3 experiences less degree of opening and effective orifice area in pulmonic …

Environmental Gradients Impact Key Leaf Traits In Riparian Trees, Amanda Malone

Electronic Theses and Dissertations

Specific leaf area (SLA) reflects a plant’s carbon investment per area and relates to generalized leaf economics spectrum growth strategies (LES). To fill gaps of knowledge about intraspecific SLA variation and why it is often inconsistent with the LES, we studied the response of two riparian tree species along the urban-rural gradient in Northeastern Colorado: an invasive, nitrogen-fixer with broad tolerances and a nitrogen-limited and shade-intolerant native. Despite these differences, the two species responded similarly, apart from the response to the urban-rural gradient, in which lower nitrogen in rural areas was associated with a more conservative strategy in the native …

Inviting The Perspectives Of Refugee Mental Health Interpreters: A Critical Narrative Analysis, Emme Y. Paik

Electronic Theses and Dissertations

The research literature lacks examination into several areas concerning mental health interpretation for refugee clients. This includes the management of interpreters’ vicarious trauma and retraumatization, interpreter’s perspectives on the appropriateness of hiring refugees as mental health interpreters, how interpreters define their trauma as well as their clients’ trauma, and support that interpreters seek for their traumatic responses from their work. The literature is also missing an analysis of how oppressive power differentials are repeated in workplace institutions, specifically for refugee mental health interpreters. Thus, this study aimed to invite the perspectives of refugee mental health interpreters on several issues pertaining …

Well-Being Development: Parents’ Perceptions Of Gifted Adolescents, Barbara Moncure Washington

Electronic Theses and Dissertations

The purpose of this study was to examine parents’ perceptions of well-being development in their gifted adolescents. This was a qualitative study that used Narrative Inquiry as a research approach. Cloninger’s (1993) Psychobiological Model of Temperament and Character the (TCI) and Clandinin and Connelley’s (2000) Three-Dimensional Narrative Inquiry Space were utilized to address the research questions: What are parents’ perceptions of temperament in their gifted adolescent? What are parents’ perceptions of character in their gifted adolescent? What are the parents’ perceptions of well-being development? Dabrowski’s Theory of Positive Disintegration (TPD) provided an analysis lens for the study.

The framework for …

The Pathophysiological Mechanisms Of Alzheimer's Disease; Investigating Therapeutic Interventions For Disease Onset, Alexandra A. Sandberg

Electronic Theses and Dissertations

Alzheimer’s Disease is a multifarious disease that progressively affects more people as both the proportion of older adults in the population and life expectancy increase in both the United States and worldwide. This devastating disease is a result of rampant neuronal loss in the memory centers of the brain that robs the independence of those who are diagnosed and places a heavy burden on those who care for them. Traditionally speaking, research has focused on the hallmark pathology of amyloid plaques, targeting them to try and prevent disease onset. However, countless failures in clinical trials aimed at this said pathology …

Crafting Up A Narrative: An Ethnographic Study Of Fair Trade Marketing Practices And The Representation Of Female Handicraft Producers, Jessica Bradley

Electronic Theses and Dissertations

Unlike the exploitative supply chains that exist under neoliberal globalization, where the social conditions of their supply chain are largely hidden; fair trade attempts to reveal the conditions of their supply chains through transparent marketing practices. Transparency is often presented in the form of storytelling wherein fair trade organizations (FTOs) reveal intimate details of the artisans they partner with to educate consumers on the interrelations of their product supply chains. I wanted to explore the implications of sharing artisan stories to further sales of the handicrafts they produced. How does sharing intimate stories of artisans formulate the perceptions Western consumers …

Dynamics And Turnover Of Lipid And Protein Domains In Cells And Supported Bilayers, Alan Weisgerber

Electronic Theses and Dissertations

Protein and lipid clustering is an important mechanism for cell processes such as exo- and endo-cytosis and creating functional signaling complexes. It has been seen that both lipids and proteins are involved with the formation of cluster domains on cell membranes, yet little is known about the interplay between the two. In this work I began with visualizing lipid sorting to artificially induced curvature in supported lipid bilayers, with lipid tails affecting the sorting differently to curvature. These results demonstrate that lipids sort to curvature on curved, supported lipid bilayers. The sorting depends on the number of lipids in the …

Antioxidant Biomarkers And Nutraceutical Therapeutics In Neurodegeneration And Neurotrauma, Lilia A. Koza

Electronic Theses and Dissertations

Mild traumatic brain injury (mTBI), yielding a Glascow Coma Scale of 13-15, is the most commonly occurring severity of TBI. Pathology from mTBI consists of blood brain barrier disruption, neuroinflammation, oxidative stress, excitotoxicity, mitochondrial dysfunction, protein aggregation, axonal degeneration, and resulting neuronal death. These processes deplete the body’s endogenous antioxidant system. We report a retrospective analysis of antioxidant blood biomarkers in patients with a history of mTBI from a local sports medicine clinic, Resilience Code. We found persistent sex-specific antioxidant depletions in mTBI patients associated with worsened symptomology.

Certain populations, such as athletes, are at high risk for repetitive mTBI …

Morphological Variation And Community Science In Orthoptera, Amy Byerly

Electronic Theses and Dissertations

Patterns of morphological divergence across species’ ranges provide insight into local adaptation and speciation. Here, we compare phenotypic divergence among 4,221 crickets from 337 populations of two related species of field cricket, Gryllus firmus and G. pennsylvanicus and their hybrids. We find that these species differ across their geographic range in key morphological traits, such as body size and ovipositor length, and we directly compare phenotype with genotype for a subset of crickets demonstrating nuclear genetic introgression, phenotypic intermediacy of hybrids, and essentially unidirectional mitochondrial introgression. We discuss how these morphological traits relate to life history differences between the species. …

Interrupting Holistic Processing May Improve The Detection Of Deceptive Emotional Facial Expressions, Christopher A. Gunderson

Electronic Theses and Dissertations

Although a growing body of evidence suggests that genuine and deceptive facial expressions differ, previous work is mixed as to whether observers can discern between them. One explanation is that cues to deception on the face are subtle and not readily perceived by observers. I argue that the way people process faces may obscure these cues, making them ‘unseen’ by observers. In the current work, I pit two hypotheses against each other to test whether interrupting holistic processing improves or impairs the ability to identify deceptive emotional expressions. Since people process faces holistically, one region of the face may interfere …

Organellar Zn2+ Homeostasis And The Role Of Trpml Channels In Neuronal Lysosome Physiology And Axonal Transport, Taylor Franklin Minckley

Electronic Theses and Dissertations

Zinc (Zn²⁺) is crucial for proper cellular function, and as such it is important to measure and track Zn²⁺ dynamics in living cells. Fluorescent sensors have been used to estimate Zn²⁺ content of subcellular compartments, but little is known about endolysosomal Zn2+ homeostasis. Similarly, although numerous sensors have been reported, it is unclear whether and how Zn²⁺ can be released from intracellular compartments into the cytosol due to a lack of probes that can detect physiological dynamics of cytosolic Zn²⁺. My dissertation started with comparing and characterizing different Zn²⁺ sensors including the …

Mobility Of Older Adults In Mexico City: A Mixed Methods Approach, Jessica Villena Sanchez

Electronic Theses and Dissertations

This dissertation covers the topic of the mobility of older adults in Mexico City using a mixed methods approach. First, I looked at the literature to uncover what is known about elderly mobilities coming from the Global South. Second, I analyzed the 2017 Household Origin Destination Survey to reveal travel behavior patterns and transport mode choice of older adults in Mexico City. Third, I revealed mobility experiences from older adults living in different neighborhoods in Mexico City by conducting twenty two telephone interviews. Lastly, I created joint displays that included both previous results to better understand how the findings from …

Experiences Of Chinese American Psychology Trainees In Multicultural Education, Helen Weng-Ian Chao

Electronic Theses and Dissertations

Although research has established that students of color have unique experiences in their multicultural training, few studies have examined the experiences and needs of specific subgroups of students of color. This study examined Chinese American psychology trainees’ experiences in multicultural education. Qualitative data was collected from individual semi-structured interviews with Chinese American doctoral students (N = 6). Interpretative phenomenological analysis was used to understand participants’ perceptions of their experiences in multicultural courses. Data analysis resulted in four themes: the (1) burden of being minoritized, (2) Chinese American identity inflection points, being (3) sidelined by whiteness, and (4) …

Executive Function And Parenting Among Latinx Caregivers Of Young Children, Amy Dominguez Fabatz

Electronic Theses and Dissertations

Supportive and responsive parenting is vital to the healthy development of young children. Parenting behaviors are determined by many factors, including caregivers’ cognitive resources and abilities such as executive functioning (EF). The present study investigated how two core dimensions of EF, working memory and set-shifting abilities, are related to parenting behaviors in a sample of Latinx caregivers of young children experiencing low income. Positive parenting was measured using a multi-method approach including video-coded observations, parent self-report, and evaluation of the home environment. Findings from hierarchical regressions indicated that caregiver working memory, but not set-shifting, predicted positive parenting as measured by …

A Sense Of Trust: Somatic Spiritual Practices As A Path To Wholeness In Spiritually Integrated Trauma Care, Shyamaa Marie Creaven

Electronic Theses and Dissertations

A traumatic event holds the power to rupture one’s world, generating lingering effects on embodied existence. Research has demonstrated that overwhelmingly stressful events often call into question deeply held values and beliefs and that spiritual struggles “tend to be partially responsible for the distress experienced" (Pomerleau et al., 2020, pp. 456–457). Similarly, research with veterans has demonstrated that religious and spiritual struggles mediate the relationship between a potentially morally injurious event and both anxiety and PTSD (Evans et al., 2018), often intensifying trauma and moral injury symptoms as well as opening a pathway for spiritual integration and growth (Pargament & …

Exploring Opportunities For Supporting Juvenile Justice-Involved Youth: A Path Forward Through Expanding Graduate Training In School Psychology, Erica L. Gleason

Electronic Theses and Dissertations

School psychologists are equipped with a dynamic skill set and an ethical and moral responsibility to support the diverse needs of all youth. While juvenile justice-involved youth may not be a primary subpopulation served by all school psychologists, they are a high-needs group that requires special consideration and attention. As a professional entity, school psychologists’ knowledge and expertise are not optimally applied to serving these youth. Consequently, school psychologists may be forgoing an opportunity to improve rates of successful school and community reintegration and overall positive life outcomes for justice-involved youth. The first manuscript of this dissertation presents precipitating and …

Banach Spaces On Topological Ramsey Structures, Cheng-Chih Ko

Electronic Theses and Dissertations

A Banach space T₁(d, θ) with a Tsirelson-type norm is constructed on the top of the topological Ramsey space T₁ defined by Dobrinen and Todorcevic [6]. Finite approximations of the isomorphic subtrees are utilised in constructing the norm. The subspace on each “branch” of the tree is shown to resemble the structure of an ℓ_∞ⁿ⁺¹ -space where the dimension corresponds to the number of terminal nodes on that branch. The Banach space T₁(d, θ) is isomorphic to (∑_n∊ℕ⊕ℓ_∞ⁿ⁺¹)_p , where d ∈ ℕ with d ≥ 2, …

Dismantling The Education-Survival Complex: A Qualitative Case Study Of How High School Youth Resist Whitestream School Policies And Foster School Change Through A Youth-Development Organization, Tracie Trinidad

Electronic Theses and Dissertations

The aim of this study is to critically examine how youth resist whitestream school policies and foster educational change through community sociopolitical youth-development organizations. The methodology for this study is a qualitative case study (Fraenkel & Wallen, 1990; Merriam, 1988), as I am focused on participant perceptions and experiences, and how they make sense of their resistance experience through participation in sociopolitical youth development organizations like Youth for Social and Political Activism (YSPA). In total, eight participants spoke about their racial identity through their lived experiences in public school and YSPA programming.

The data and analysis are presented in the …

Faculty Facilitation Of Help-Seeking On Campus: A Phenomenological Study, Lillian V. Clark

Electronic Theses and Dissertations

An ever-increasing number of students on college campuses are experiencing distress, and not all students in need of care are being reached (Kitzrow, 2009, LeViness, et al., 2019). Faculty are one of the most valuable resources for identifying and connecting students to care (Kitzrow, 2009). Despite this, we know very little about the experiences of faculty working with students in distress. This study sought to understand those experiences, as well as identify the barriers to connecting students to care. A qualitative study using an Interpretive Phenomenology framework was conducted (Smith & Osborn, 2007, Moustakas, 1994). Four themes were interpreted from …

Multicultural Perceptions Of Creativity, Abby Noel Winterbrook

Electronic Theses and Dissertations

Multicultural Perceptions of Creativity examined perceptions of creativity among eight creatively gifted adults from diverse backgrounds who have a profession in an arts related field. This study examined what the phenomenon of creativity is and how it is experienced. The beliefs that inform perceptions of creativity were explored. The experiences that inform perceptions of creativity were described. The interactions among beliefs and experiences were considered. The data collected revealed that creativity is an instinct that each person possesses and can activate within themselves. Creativity can be nurtured based on environment and through personal, educational, professional, and cultural experiences. Creativity involves …

“I, Too, Am An Occupied Territory”: Border Crossings And Personal Sovereignty In Three Novels By Dominican American Women, Leia M. Lynn

Electronic Theses and Dissertations

Border crossing(s) and personal sovereignty are intimately and complexly connected in novels by and about Dominican American women. Through readings of In the Name of Salomé by Julia Alvarez, Dominicana by Angie Cruz, and The Poet X by Elizabeth Acevedo, I argue that patriarchal forms of authority remove female autonomy by trespassing on personal boundaries, and that the renegotiation of that power is achieved through formations of community, especially with other women, through nonheteronormative relationships that are present inside and extend outside the text. The interplay of patriarchal authority, violence, and alienation on the four protagonists is examined at length, …

Improving Vocabulary Outcomes Through Language Resources: A Single Case Design Of First Grade Emergent Bilinguals Engaged In Literacy Intervention, Brooke S, Coté

Electronic Theses and Dissertations

While there is a strong literature base demonstrating the importance of early literacy interventions for monolingual learners at-risk for reading difficulties, little research exists on how to effectively support the literacy needs and language assets of emergent bilinguals. The purpose of this study was to investigate the effect of an evidence-based reading intervention with a translanguaging component, on vocabulary outcomes for first grade emergent bilinguals. By utilizing an alternating treatment single case design with two conditions, this project aimed to address the following research questions: Is there a functional relationship between an evidence-based reading intervention with a translanguaging component compared …
