Publication Publication There’s a New Crown in Town: Synthesis and Characterization of a Uranyl Complex Supported by a Nitrated Crown Ligand(University of Kansas, Department of Chemistry, 2025-05)By studying the manner in which the uranyl ion interacts with various types of ligand systems, fundamental chemical insights can be obtained which could lead to innovation in the fields of radiochemical separations and nuclear fuel reprocessing. Such innovations could be developed into technologies for supporting a cleaner world and greener energy system. In this thesis, the synthesis and characterization of a novel aza-crown ligand, LDNO, and its metalated counterpart UO2LDNO is outlined, along with electrochemical analysis and crystallography. UO2LDNO is a member of a new class of aza-crown ligands for uranyl coordination that are being synthesized by the Blakemore Group at KU, and this ligand is unique as it is appended with nitro groups. Insight into uranyl redox stability and the role of ligand radicals in uranium chemistry can be studied with this system. UO2LDNO was prepared with straightforward synthesis procedures, and nuclear magnetic resonance (NMR) data provide evidence of the presence of multiple conformational isomers of UO2LDNO in solution. Among these isomers, there is a minor 3% component which could correspond to non-crown-encapsulated species. LDNO undergoes a quasi-reversible, 2e– reduction with E1/2 = –1.56 V vs. the ferrocenium/ferrocene (Fc+/0) couple, corresponding to reduction of each [NO2] group. Scanning anodically reveals an amine-centered oxidation near +0.7 V vs. Fc+/0 and a paired follow-up reduction feature at –1.1 V. Both the nitro-centered reduction(s) and amine oxidation appear during electrochemical analysis of UO2LDNO, the data for which features an additional chemically reversible UVI/V reduction at a rather positive E1/2 value of ¬¬–390 mV. Considering all this, UO2LDNO affords ready access to unique redox chemistry, including formation of U(V) species with ligand radicals derived from the nitro groups found on the ligand substituents. Built on the current foundation of results, future work is planned to chemically and electrochemically interrogate the properties of the radical species that can be generated on the UO2LDNO platform.Publication A Conceptual Framework for Intercultural Teaching Practices in Undergraduate Music Therapy Learning Environments(University of Kansas, 2023-05-31)The field of music therapy has seen an increase in research pertaining to culture and cultural considerations within the last several years, mainly focusing on topics such as culture, race, gender and sexuality, and disability. Many publications center on cultural considerations as they pertain to music therapy clinical facilitation. However, not much has been written on cultural considerations within undergraduate music therapy classrooms, and even less on interculturality within music therapy. The purpose of this thesis is to explore intercultural teaching practices within undergraduate learning environments and to develop a framework detailing the relationship between intercultural teaching practices and intercultural clinical practices. To create this framework, an ethnographically informed approach was conducted. A review of existing literature was provided, and the relationships among culture, intercultural awareness, intercultural teaching practices, and intercultural music therapy practice were described.Publication Assessing the Effects of Video Modeling on the Acquisition and Performance of Taekwondo Kicks in Children Diagnosed with Autism(University of Kansas, 2023-12-31)Only a few studies using group designs have examined the effects of martial arts training in children with ASD, but the results have been promising, demonstrating improvements in social interactions and exercise (Movahedi et al., 2013), as well as reductions in stereotypical behaviors (Bahrami et al., 2012). The present study assessed the effectiveness of video modeling on the acquisition and performance of three Taekwondo kicks (round kick, side kick, and hook kick) in children diagnosed with autism spectrum disorder using a multiple probe design. If video modeling as a stand-alone intervention was ineffective, behavioral coaching was implemented as a package intervention comprising of video modeling, video feedback, and verbal feedback. The results showed four of the five participants met mastery criterion on all three kicks with at least one of the interventions assessed. The fifth participant did not meet mastery on the hook kick but did achieve 81% of steps completed correctly. Mike and Ash required the behavioral coaching intervention to meet mastery across all three kicks. The other three participants required behavioral coaching to meet mastery on at least one of their kicks. Results showed naive participants may need additional instruction using behavioral coaching to master the target kicks, as video modeling alone was not effective to meet mastery criterion across all three kicks for any of the participants in this current study. Future research should conduct a component analysis to determine the independent contributions of each standalone intervention within the behavioral coaching package.Keywords: video modeling, behavioral coaching, Taekwondo, autismPublication Wakarusa River Valley Heritage Museum Capstone(University of Kansas, 2025-04-25)The Wakarusa River Valley Heritage Museum is a place dedicated to the valley’s history, honoring the communities forcefully displaced for the construction of Clinton Lake. This project has resulted in the creation of three educational signs for the museum’s exterior, as well as a 3D model representing the valley and its historical landmarks prior to construction of the dam. The signs will focus on the history of Bloomington, the Wakarusa River Valley Community, and the Freedom Rings public art installation. Additionally, through extensive historical research into the location of displaced communities in the valley, our team was able to utilize ArcGIS software to spatially visualize historical landmarks that no longer exist. This research and ArcGIS utilization resulted in the construction of a 3D model that accurately depicts the features present before Clinton Lake existed. Through the creation of signage and the 3D model, the story of forced displacement in the Wakarusa River Valley can be accurately depicted. In the process, it will increase accessibility to education about the historical significance of the Wakarusa River Valley, spread awareness about the impacts of displacement, and help to visualize the valley prior to construction of the dam. In doing so, we hope to pay homage to the Wakarusa River Valley Heritage Museum and the communities they represent: Bloomington, Clinton, Sigel, Kanwaka, Stull, Richland, Twin Mound, Belvoir, and Lone Star.
