12 Études Caractéristiques, Opus 2, by Adolf von Henselt: A Pedagogical Guide with Practical Exercises on Selected Etudes
Adolf von Henselt (1814–1889) was one of the most renowned German pianists and composers of his day. The majority of his compositions are for the piano, one of his most successful being the set of Piano Études, Op. 2. It consists of twelve etudes, each of which is designed for developing a particular technique. Henselt's etudes are as demanding as Chopin's and Liszt's, so this pedagogical guide is designed for advanced-level students. Henselt uses many finger extensions and stretches larger than an octave, which may be difficult for smaller hands to play, but proper flexibility and relaxation should enable all students to play them. This dissertation describes the specific technique for six selected etudes and provides exercises to help students learn each technique effectively. The selected etudes—Nos. 1, 2, 3, 6, 9, and 11—were chosen to cover all three technical levels of less-advanced, advanced, and very advanced as well as a variety of musical styles and technical challenges.

Accommodating People Safety Curriculum for Deaf and Hard of Hearing Students
Children with disabilities are three to four times more likely to be abused than their non-disabled peers due to the impact of challenges related to behavior, cognition, language, social skills, and communication skills. In September of 2018, the Council for Exceptional Children (CEC) specifically noted the need to establish maltreatment prevention and response curricula and promote research and advocacy surrounding maltreatment of children with disabilities. One common curriculum recommended is Kidpower®. While Kidpower® shows promise in increasing people safety skills and offers some basic accommodations for use with disabled populations, a complete accommodation plan for deaf or hard of hearing students has not been developed. The purpose of this study was to explore how Kidpower® curriculum could be accommodated to meet the unique needs of deaf and hard of hearing students from the perspective of the deaf education community, including deaf adults, deaf education teachers, deaf education teacher preparation faculty, and parents with deaf or hard of hearing children. A combination of focus groups and interviews were utilized to review lessons and homework from the Kidpower® curriculum. Participants gave feedback on obstacles and ideas for accommodations and modifications that would mediate the challenges. Data were inductively coded and analyzed for …

Activating Artistry: Community Engagement Resources and Teaching Artist Strategies for the Bassoonist
This document examines current practices and opportunities in the music performance field related to artistic citizenship, community engagement, and the field of teaching artistry. The relationship of musicians to their audiences and communities has shifted significantly in the twenty-first century, and there is an increasing need to redefine the essential skills of the professional musician. Derived from the field of teaching artistry, the concept of "activating artistry" suggests that our greatest strength and power as artists lies in drawing out individual artistic expression in other people, and it is with this power that artists as a workforce can create meaningful change in society. This intention could be manifested in many different contexts during the course of a given music career, however, developing the tool kit necessary for engaging in such work is not widely emphasized in the training of musicians. What tools can be provided for students and professionals to help them navigate both traditional and evolving career paths in music? How are bassoonists doing as a field in addressing the imperative of community engagement and artistic citizenship? How might we explore more collaborative ways to engage with our diverse communities – ways that value their perspectives? These questions guide …

Activation of Small Molecules by Transition Metal Complexes via Computational Methods
The first study project is based on modeling Earth abundant 3d transition-metal methoxide complexes with potentially redox-noninnocent ligands for methane C–H bond activation to form methanol (LnM-OMe + CH4 → LnM–Me + CH3OH). Three types of complex consisting of tridentate pincer terpyridine-like ligands, and different first-row transition metals (M = Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) were modeled to elucidate the reaction mechanism as well as the effect of the metal identity on the thermodynamics and kinetics of a methane activation reaction. The calculations showed that the d electron count of the metal is a more significant factor than the metal's formal charge in controlling the thermodynamics and kinetics of C–H activation. These researches suggest that late 3d-metal methoxide complexes that favor σ-bond metathesis pathways for methane activation will yield lower barriers for C–H activation, and are more profitable catalyst for future studies. Second, subsequently, on the basis of the first project, density functional theory is used to analyze methane C−H activation by neutral and cationic nickel-methoxide complexes. This study identifies strategies to further lower the barriers for methane C−H activation through evaluation of supporting ligand modifications, solvent polarity, overall charge of complex, metal identity and counterion …

The Adaptation of Saxophone-Like Phrasing into the Improvisatory and Compositional Vocabulary of Jazz Guitar: A Comparative Analysis of Phrasing, Articulation, and Melodic Design in the Styles of Jimmy Raney, Jim Hall, and John Scofield
This study investigates how different guitarists introduced saxophone-like phrasing into the improvisatory and compositional vocabulary of jazz guitar through their collaborations with saxophonists. This research presents a comparative analysis of phrasing, articulation, and melodic design in solo improvisations. The mixed approach to this study includes analysis of motives, voice leading, articulation, length of phrases, melodic contour, and the execution of bebop vocabulary on the guitar. The findings are based on original transcriptions from significant recordings by guitar-saxophone pairs. These highlight the similarities between and adaptations of musical devices from saxophonists Stan Getz, Jimmy Giuffre, and Joe Lovano into the jazz guitar styles of Jimmy Raney, Jim Hall, and John Scofield. This study supports the argument that the evolution of modern jazz guitar playing is directly connected to the adaptation of saxophone-like phrasing at an improvisatory and compositional level. It also shows that the concept of style in jazz flows between different instruments' lineages. Understanding these findings provides a more complex and accurate concept of the development of style in jazz.

The Administration of Unemployment Relief by the State of Texas during the Great Depression, 1929-1941
During the Great Depression, for the first time in its history, the federal government provided relief to the unemployed and destitute through myriad New Deal agencies. This dissertation examines how "general relief" (direct or "make-work") from federal programs—primarily the Emergency Relief and Construction Act (ERCA) and Federal Emergency Relief Administration (FERA)—was acquired and administered by the government of Texas through state administrative agencies. These agencies included the Chambers of Commerce (1932-1933), Unofficial Texas Relief Commission (1933), Texas Rehabilitation and Relief Commission (1933), Official Texas Relief Commission (1933-1934), Texas Relief Commission Division of the State Board of Control (1934), and the Department of Public Welfare (1939). Overall, the effective administration of general relief in the Lone Star State was undermined by a political ideology that persisted from, and was embodied by, the "Redeemer" Constitution of 1876.

Adolescent Self-Theories of Singing Ability within the Choral Hierarchy
The purpose of this study was to explore adolescent self-views of singing ability through both implicit theories and self-concept meaning systems. A secondary purpose of this study was to examine these self-views specifically in the context of a choral hierarchy. Using a researcher-designed survey instrument, I gathered data from middle- and high-school students currently enrolled in a choir program organized in a hierarchical structure. I analyzed descriptive statistics of survey responses to items designed to measure implicit theories of singing ability, singing self-concept, and goal orientation. I also examined differences among participants by ensemble placement in implicit theory and self-concept scores, correlation between implicit theory and self-concept, and whether implicit theory, self-concept, goal orientation, or current enrollment could predict future enrollment decisions. In addition to these quantitative measures, I coded open-ended responses to two failure scenarios and examined participant responses by ensemble and gender. Both implicit theory and self-concept scores were higher for participants at the top of the choral hierarchy than at the bottom. Open-ended responses, however, did not align with the implicit theory scale and a number of students presented a false growth mindset. Open-ended responses also indicated that failure scenarios were likely to result in an altered …

Adoption of Wearable Devices by Older Adults
This dissertation is organized in a traditional format while including three essays that address specific research questions. Essay 1 examined the relationship between physical activity and community engagement and their effect on mental well-being among older men and women. Data from National Health and Aging Trends Study (NHATS) from 2018 to 2020 were explored and the posited relationships were tested. This essay provides empirical support that older adults who are reasonably active and involved in the community have greater mental well-being than those who isolate themselves. Essay 2 provides insight into older adults' motivation to improve their physical activity through the use of a fitness tracker. The key finding from this study is that wearables, especially fitness trackers, can significantly facilitate increased physical activity. Essay 3 is a mixed-methods study to understand older adults' perception of the usefulness of fitness trackers and interaction with such devices. Findings suggest that to increase the adoption of fitness trackers among older adults, makers could improve the esthetics and quality of the wristband in addition to the battery life of the tracker.

Adult Attachment Anxiety and Relationship Satisfaction: The Role of Dedication and Constraint Commitment
Adult attachment has been found to play an important role for romantic relationship satisfaction. Specifically, the existent literature generally suggests that attachment anxiety is negatively related to relationship satisfaction. However, the underlying mechanism for this link still needs further exploration. The present study examined the direct and indirect effect of attachment anxiety on relationship satisfaction via two distinct relationship commitment variables: constraint commitment and dedication commitment. The final sample included 146 unmarried participants who were in a romantic relationship for at least three months. Results of multiple regression analyses on the indirect effect model indicated that attachment anxiety had a significant direct effect on relationship satisfaction as well as a significant indirect effect on relationship satisfaction via constraint commitment. However, the hypothesized indirect effect through dedication commitment was not supported. Findings are discussed from the adult attachment perspective. Counseling implications, limitations, and future research directions are outlined.

Advanced Distributed Optimization and Control Algorithms: Theory and Applications
Networked multi-agent systems have attracted lots of researchers to develop algorithms, techniques, and applications.A multi-agent networked system consists of more than one subsystem (agent) to cooperately solve a global problem with only local computations and communications in a fully distributed manner. These networked systems have been investigated in various different areas including signal processing, control system, and machine learning. We can see massive applications using networked systems in reality, for example, persistent surveillance, healthcare, factory manufacturing, data mining, machine learning, power system, transportation system, and many other areas. Considering the nature of those mentioned applications, traditional centralized control and optimization algorithms which require both higher communication and computational capacities are not suitable. Additionally, compared to distributed control and optimization approaches, centralized control, and optimization algorithms cannot be scaled into systems with a large number of agents, or guarantee performance and security. All of the limitations of centralized control and optimization algorithms motivate us to investigate and develop new distributed control and optimization algorithms in networked systems. Moreover, convergence rate and analysis are crucial in control and optimization literature, which motivates us to investigate how to analyze and accerlate the convergence of distributed optimization algorithms.

Alloy Design, Processing and Deformation Behavior of Metastable High Entropy Alloys
This dissertation presents an assortment of research aimed at understanding the composition-dependence of deformation behavior and the response to thermomechanical processing, to enable efficient design and processing of low stacking fault energy (SFE) high entropy alloy (HEAs). The deformation behavior and SFE of four low SFE HEAs were predicted and experimentally verified using electron microscopy and in-situ neutron diffraction. A new approach of employing a minimization function to refine and improve the accuracy of a semi-empirically derived expression relating composition with SFE is demonstrated. Ultimately, by employing the minimization function, the average difference between experimental and predicted SFE was found to be 2.64 mJ m-2. Benchmarking with currently available approaches suggests that integrating minimization functions can substantially improve prediction accuracy and promote efficient HEA design with expansion of databases. Additionally, in-situ neutron diffraction was used to present the first in-situ measurement of the interspacing between stacking faults (SFs) which were correlated with work hardening behavior. Electron transparent specimens (< ~100 nm thick) were used in order to resolve nanoscale planar faults instead of the thicker sub-sized specimens (on the order of millimeters in thickness) which exhibit the classical stages III work hardening behavior characteristic of low SFE metals and alloys. …
