The following research questions guided the study:

Q1 How do professional improvising music educators define creativity?

Q2 How does the creative process manifest itself within their performance and teaching?

Through purposeful sampling, four participants were selected and interviewed to collectively create 7-8 hours of narrative data producing 200 pages of data. Participants as creative specialists were selected …

A Randomized Clinical Trial Exploring Two Doses Of Cannabidiol Daily For Eight Weeks On Health And Stress, Ryland Emery Townsend

Dissertations

This study’s purpose was to explore whether a 60 or 30 mg dose of cannabidiol (CBD) consumed in a beverage further supplemented with L-theanine, vitamin E, and vitamin C would alter various measures on subjective measures of stress, health and fitness related outcomes, and objective measures of stress. This double-blind, placebo-controlled clinical trial recruited healthy, college-aged subjects for randomization into one of four treatment groups where they consumed daily a single 12 ounce beverage for eight weeks containing 1) 60 mg CBD (CBD60) plus L-theanine; 2) 30 mg CBD (CBD30) plus L-theanine; 3) no CBD (CBD0), L-theanine alone, and 4) …

Exploring The Utility Of A Behavior Assistant Position In One School District, Carolyn Christine Mitchell

Dissertations

Challenging student behavior is on the rise with increased verbal and physical aggression in schools. Some students who exhibit challenging behavior are identified with a disability and served under Individuals with Disabilities Education Act of 2004 or Section 504 (U.S. Department of Education, Office for Civil Rights, 2022). Legal mandates required schools to implement positive and proactive behavior supports for students who exhibited challenging behavior; however, teachers were not adequately trained in such legal requirements or effective behavior management strategies. This lack of training resulted in an over-reliance on reactive disciplinary reactions such as suspension, expulsion, restraint, and seclusion. These …

New Nursing Faculty Perspectives On And Experiences With Group Mentoring, Kathryn Donna Kuskie

Dissertations

Nursing faculty are needed to teach the next generation of nurses. However, there is a current shortage of nursing faculty. The transition to nursing education from clinical practice is a difficult one, which has led many to leave education to return to nursing practice instead of successfully transitioning to the nurse educator role. Strategies are needed to support nurses in making the transition from practice to education. Mentoring has shown promise in aiding this transition. Many studies explored mentoring of new nursing faculty, but few studied group mentoring with this population. Limited research showed that group mentoring might have benefits …

Preschoolers naturally learn and develop within their environments and communities. Itinerant early childhood special education (ECSE) services within community-based settings such as homes, childcare locations, and private preschool programs are used in some areas to provide inclusive services. Key collaborators to this model include families, ECSE professionals, and early childhood education (ECE) staff (Division for Early Childhood [DEC] & National Association for the Education of Young Children [NAEYC], 2009). The purpose of this study was to explore and describe the experiences and perspectives of adult collaborators in a single case of a Wisconsin district implementing itinerant ECSE services in community-based …

Sexual And/Or Gender Minority (Sgm) Stigma Within Nursing Schools: The Relationship Between Stigmatic School Attributes, Minority Stressors, And Sgm Nursing Student Mental Health, Michelle Gee

Dissertations

Nursing education is heteronormative and cis-normative, which has been correlated to stigma and ignorance exhibited by nurses towards sexual and/or gender minorities (SGM). Minority Stress Theory (MST) states that circumstances in the environment that promote stigma related to minority identities lead to unique minority stressors, such as discrimination. These minority stressors subsequently affect mental health. While it is known that SGM patients experience mental health issues that relate to stigma and discrimination in healthcare settings, nothing is known about SGM nursing students dealing with stigma and discrimination within nursing education. The aim of this descriptive correlational study was to inform …

Unschoolers In Higher Education: A Narrative Case Study Of Unschoolers’ Sense Of Belonging At University, Melissa Marie Carlson

Dissertations

Approximately 20% of families engaged in homeschooling have selected unschooling as their educational approach, with estimates suggesting this number may be even higher (Vesneski et al., 2022). Unschooling emphasizes the establishment of an environment where children can autonomously direct their learning by exploring their interests, unencumbered by traditional educational milestones or specific schedules (Arnall, 2018; Riley, 2020; Riley & Gray, 2015). Despite increasing public acceptance and recognition, research on the outcomes for unschoolers—particularly those pursuing higher education—is limited (Riley, 2020). The purpose of this study was to explore the importance of supporting unschoolers after they have matriculated, specifically fostering sense …

Production Pressure And Normalization Of Deviance: An Examination Of Their Prevalence Among Certified Registered Nurse Anesthetists In Their Primary Clinical Practice Setting, Jeremy Stephen Carter

Dissertations

Normalization of deviance (NoD) occurs when an individual intentionally and repeatedly circumvents established standards of care, professional regulations, or institutional policies designed to maintain safety. Over time, these violations become incorporated into the individual’s routine until they are no longer viewed as safety threats but as acceptable means to achieving organizational goals. Production pressure (PP) occurs when an individual perceives pressure to maximize productivity—either from another individual or administrators within an organization. Production pressure is frequently cited as a leading cause of NoD within all industries. The purpose of this study was to examine the prevalence of PP and NoD …

Understanding The Impact Of Fall Armyworm (Spodoptera Frugiperda) Feeding, And Drought Stress On Drought-Tolerant And Drought-Resistant Soybean (Glycine Max)., Adriana G. Peissel

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Drought and insect herbivory are two major stressors on high-value crops like soybean (Glycine max). However, few studies have explored how these stressors interact, despite their presence in tandem under field conditions. We investigated how drought stress and fall armyworm (Spodoptera frugiperda) caterpillar herbivory impact Magellan (drought-tolerant) and Blackhawk (drought-susceptible) soybean cultivars. The soybean plants were subject to four treatment groups (1. Drought 2. Herbivory 3. Drought + Herbivory 4. Well-Watered) during a treatment period of 7 days in a greenhouse. We then measured plant height, physiological traits, trichome density, soil moisture, and larval mass gain. …

Silver Nanoparticles In Ammonia Sensing And Photovoltaics, Madhuka Liyanage

All Dissertations

Nanocomposite films (NCF) containing silver nanoparticles (AgNPs), separated by thin layers of silica/poly-4-vinylpyridine/polyvinylpyrrolidone, were fabricated via drop casting, spin coating, dip coating on glass substrate and drop casting on nylon filter membranes. The more uniform films were produced by drop casting on nylon filter membranes due to their solvent wicking properties. The films demonstrate electrical conductivity that varies in response to moist ammonia and water vapors. The changes in conductivity are attributed to hydrogen bonding between ammonia and water molecules with the silica/polymer layers, as well as the direct adsorption of ammonia onto the silver surface. Notably, NCFs with polyvinylpyrrolidone …

Growth, Cladding, And Characterization Of Single Crystal Optical Fiber: The Next Evolution In Directed Energy Systems, Allen Benton

All Dissertations

High-power fiber lasers are steadily increasing in maximum power and rapidly approaching theoretical maximum power output from a single fiber aperture. The low thermal conductivity of silica fibers is an inherent limitation to the dissipation of heat from the fiber core, and the buildup of heat within the laser gain media is the principal driver of transverse mode instability within fiber systems. This limitation necessitates the exploration of alternate fiber host materials. Due to their high thermal conductivity, excellent transmission range, ability to host most of the optically active rare earth ions, and success as bulk laser materials, single-crystalline YAG …

By combining IMS separations with mass spectrometry and targeted chemical derivatization, this work enhances the ability to distinguish and characterize …

Development Of Rolipram Loaded Pgp Nanoparticles For Spinal Cord Injury Repair, Zhen Liao

All Dissertations

Spinal cord injury (SCI) leads to devastating neurological deficits due to primary mechanical damage and secondary injury mechanisms, including inflammation, oxidative stress, excitotoxicity, and inhibitory scarring, which collectively impede neural regeneration. One key aspect of SCI pathology is a significant reduction in cyclic adenosine monophosphate (cAMP) levels, primarily due to increased phosphodiesterase (PDE 4) activity. As a ubiquitous second messenger, cAMP regulates key signaling pathways, including protein kinase A (PKA) / cAMP response element-binding protein (CREB) and exchange protein activated by cAMP 2 (EPAC2). Therefore, restoring/increasing cAMP level is one of the major therapeutic strategies to reduce neurotrauma and restore …

The Evolution Of Nanoparticles In Nanoparticle Doped Optical Fibers, Mary Cahoon

All Dissertations

Optical fiber and fiber laser technologies based on silica glass are critical to many technologies today. One method to improve the optical performance of laser fibers is engineer the local environment around the active elements in the glass. To that end, this Dissertation focused on the fabrication and characterization of fibers made with nanoparticles incorporated into the glass to control the local composition. First, the nanoparticle composition and structure was analyzed as it evolved from from the initially-synthesized form to incorporation into the dense aluminum-silicate glass. The aluminum oxide in the glass was found to be important not only to …

Rhetorics Of Vigilance: Refracting Discourses In Technologies Of Self-Managed Health & Wellness, Haley Swartz

All Dissertations

Rhetorics of Vigilance explores the limits of feminist health rhetorics by examining technologies that promote women’s self-managed health and wellness practices. By establishing a corpus of personal health technologies and associated texts including mobile health applications, pelvic floor training devices, and perimenopause information shared on social media, this dissertation analyzes how discourses refract––redirected and often distorted––to implicate women in persistent self-monitoring. Drawing from interdisciplinary scholarship on women’s health from feminist rhetorical studies, rhetorics of health and medicine, science and technology studies, and digital studies, I theorize rhetorics of vigilance as a framework through which women understand and interpret issues …

Development Of Translational Microscale Systems To Interrogate How Biophysical And Biochemical Cues Alter The Phenotype Of Hormone Positive Breast Cancer, Braulio Ortega Quesada

All Dissertations

Cancer is a complicated disease and one in every three diagnoses are women with breast cancer. Recent research shows that the progression of cancer depends strongly on interactions with other non-cancerous cells and non-cellular components. Metastasis, the spread of cancer to other parts of the body, is a key step in cancer progression and makes treatment harder, leading to poor response to treatments culminating in death in ~90% of patients. This dissertation focused on creating a series of microdevices as novel pre-clinical models of breast cancer. Two different devices were fabricated to (1) study how exposing cancer cells to the …

Operationalizing Quality Youth Leadership Programs Within The Context Of Summer Camps, Leslie E. Heffington

All Dissertations

Positive youth development (PYD) exists in a variety of out-of-school time settings. Research has demonstrated that PYD occurs when there is an alignment between ecological assets and individual capabilities (Lerner et al., 2005). Participation in youth programs can be a successful strategy for promoting PYD because they can offer youth relationships with supportive adults (Henderson, 2007) who provide opportunities for skill building and community connection (Lerner, 2004). More specifically, the camp setting has been shown to offer a variety of positive outcomes for youth by providing developmental opportunities across social, physical, cognitive, and spiritual domains of adolescent development (Garst et …

The Effect Of Storyline Units On The Self-Efficacy And Science Identity Of High School Multilingual Learners, Kristin Ambrose

All Dissertations

Science can be a complex subject for multilingual learners (MLLs) because it requires investigating science concepts through modeling and analysis in addition to reading and writing skills. This complexity often leaves teachers unsure of how to support the MLLs, leading to MLLs missing out on grade-appropriate content and science experiences. Storyline instruction uses 3D instruction to teach science content necessary to explain a real-world anchoring phenomenon. Storyline instruction grounds learning in real-world contexts through anchoring phenomena and provides coherence for students throughout the lessons. This mixed methods study aimed to discover the impact of storyline units on the self-efficacy (SE) …

Decision Space Decomposition For Multiobjective Programs, Emma Soriano

All Dissertations

Being inspired by the parametric decomposition theorem for multiobjective optimization problems (MOPs) of Cuenca and Miguel (2017), and by the block- coordinate descent for single objective optimization problems, we present a decom- position theorem for computing the set of minimal elements of a partially ordered set. This set is decomposed into subsets whose minimal elements are used to retrieve the overall minimal elements. We apply this approach to strictly convex MOPs de- composing their decision space into lines. The line decomposition benefits from the fact that a multiobjective line search problem is equivalent to solving a collection of single objective …

The Quest For Kindergarten Readiness: A Study Of One District’S Early Implementation Of The Pyramid Model For Promoting Social-Emotional Competence, Ginny L. Gast

Adaptive Delay Compensation Frameworks For Distributed Real-Time Co-Simulation In Power Systems, Elutunji Buraimoh

All Dissertations

This dissertation presents a model-free, adaptive delay prediction and compensation framework for geographically distributed real-time power system co-simulation environments. Communication delays—both constant and real-time-varying—significantly degrade the accuracy, fidelity, and stability of co-simulated systems, particularly in dynamic and transient analyses of partitioned power systems. To address this, a predictor-based framework is developed that compensates for delays without requiring system models, computationally intensive signal transformations, or manual intervention.

The proposed solution leverages a Damping Impedance Method as the interface algorithm, combined with a sliding-mode control-inspired predictor system. Both single-parameter and multi-parameter predictor configurations are implemented, with the multi-parameter design providing an additional …

Toward The Application Of Natural Language Processing In Electronic Health Record Analysis For Taxonomy Development, Latoya Mcdonald

All Dissertations

Electronic health records (EHRs) are pivotal resources for nurse practice because they increase the timeliness and reliability of patient information at the point of care and support access by multiple healthcare providers and the individual patients themselves. However, it is widely recognized that data extraction from EHRs is challenging due to the variability in the language used in clinical care notes and the lack of standardized terminology across healthcare systems. The broad objective of this dissertation is to develop taxonomy-based classification models for nursing care by applying feature engineering approaches to EHRs that include nursing care of ostomy patients following …

Development Of Small-Molecule Inhibitors For Bacteroides, Naegleria, And Toxoplasma Microorganisms And Synthesis Of N-Heterocycles From Thiolated Ene-Ynes And Azodicarboxylates, Samuel Kwain

All Dissertations

Humans and microorganisms are intricately interconnected, with microbes constituting an essential component of human biology and ecology. This interdependence necessitates a delicate balance between leveraging beneficial microbes and mitigating the impact of harmful ones. The human gut microbiome, home to trillions of microorganisms, predominantly comprises commensal species that support health. However, dysbiosis within this ecosystem has been linked to serious diseases. For instance, an overrepresentation of Bacteroides species is associated with Type I diabetes mellitus (T1D) and various chronic gut disorders, including ulcerative colitis, inflammatory bowel disease, celiac disease, and colorectal cancer. Similarly, Naegleria fowleri, a free-living amoeba, causes …
