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.

The Abraham solvation model (ABSM) is an experimentally derived predictive model used to help predict various solute properties. This work covers various uses for the ABSM including predicting molar enthalpies of vaporization, predicting solvent coefficients for two new solvents (2,2,5,5-tetramethyloxolane and diethyl carbonate), predicting values for multiple new ionic liquids (ILs). This work also introduces a novel method for updating IL ABSM parameters by updating cation- and anion-specific values using linear algebra and binary matrices.

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 …

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 …

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 …

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.

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.

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 …

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 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.

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.

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. …

As technology has advanced, data has become more and more important. The more breakthroughs are achieved, the more data is needed to support them. As a result, more storage is required in the system's memory. Compression is therefore required. Before it can be stored, the data must be compressed. To ensure that information is not lost, efficient compression is necessary. This also makes sure that there is no redundancy in the data that is being kept and stored. Compressive sensing has emerged as a new field of compression thanks to developments in sparse optimization. Rather than relying just on compression and sensing formulations, the theory blends the two. The objective of this thesis is to analyze the concept of compressive sensing and to study several reconstruction algorithms. Additionally, a few of the algorithms were put into practice. This thesis also included a model of the ECG, which is vital in determining the health of the heart. For the most part, the ECG is utilized to diagnose heart illness, and a modified synthetic ECG can be used to mimic some of these arrhythmias.

Although behavioral science, due to its emphasis on the use of single-subject research design, appears to focus solely on individual behaviors, behavioral scientists have a long history of lamenting the trajectory of humans, societies, and the discipline itself. Some scholars, for instance, called for our attention to expand our focus beyond individual behaviors to generate solutions for societal issues that we face. When we attempt to develop solutions for issues that require multi-level analysis, we must be cognizant of how institutional contingencies operate at the individual level. The current study analyzed triadic interactions using an exchange task in six triads. The result of this study showed that one common pattern of interactions among participants across triads was direct reciprocation between two participants. The implications of such findings, how they inform social behavior and metacontingency experiments, and future directions are discussed.

In this paper, I analyze the musical content in Federico Alvarez del Toro's marimba concerto El Espiritu de la Tierra. This dissertation represents my analysis of features I hear in the composition, and does not reflect the composer's original compositional process. Commissioned by the governor of Chiapas, the piece was composed in collaboration with internationally renowned marimba virtuoso Zeferino Nandayapa and premiered in 1984 with the Philharmonic Orchestra of Mexico City at Festival Cervantino in Guanajuato. The work has not been published and has been mentioned only briefly in scholarship. Particular attention in the analysis is given to indigenous and folk idioms from the southern region of Mexico combined with post-modern compositional techniques. My primary argument within the dissertation is that I believe the piece demonstrates a respect for tradition and heritage while concurrently utilizing non-traditional and contemporary compositional techniques. Analytically, I argue that two basic shapes are used throughout the piece, and I argue that the many cultural references within the piece solidify a preoccupation with the lineage of southern Mexico.

The Texas High Plains produces the most substantial amount of cotton in Texas. The region is a semi-arid area with limited precipitation, and it is, therefore, susceptible to climate change. Cotton production in the Texas High Plains is mostly dependent on irrigation to increase yield. The overall goal of this research was to study the interrelationships between climate change and cotton yield using correlation analysis and also to study how climate has changed in the region using trend analysis. A three-decade data (1987-2017) was analyzed to establish the relationship between climate change and cotton and also to determine how climate has changed in the area over the last 30 years. The research used precipitation and temperature data to assess climate change.The results of this research showed that annual mean temperature has lesser impacts on cotton yield, and the correlation between annual precipitation and cotton yield is insignificant. It also found out that high rates of temperature at the boll opening stage of cotton growth results in decreased cotton yield and that at the boll development and boll opening stages, precipitation is needed. Again, the research indicated that, on average, there had been a significant increase in temperature, but precipitation trends …

The flypaper effect states that grants-in-aid increases public spending more than a comparable increase in personal income. If aid increases spending, then there is the possibility that it displaces own-source revenue or a portion of the aid itself is used to meet other priorities of governments, fungibility. Different local government structures have the tendency to prioritize either the operating or capital budget. Empirical evidence shows that federal and state grants have different flypaper effect. While fungible state aid is allocated to the operating budget, that of federal goes to the capital budget. Council-manager and mayor-council form of governments do not allocate fungible intergovernmental aid differently between the capital and operating budgets.

Hendrik Hofmeyr is considered one of the most important and influential living composers in South Africa. His music for solo saxophone is not well-known in the classical saxophone repertoire. His four works for solo saxophone (Concerto per saxofono contralto e orchestra, Concerto per saxofono baritono e orchestra, Partita canonica, and Necromancer) are substantial and terrific repertoire for the instrument. This study is intended to inform a saxophone performer's understanding of these compositions through analysis of form, melodic, and harmonic content relevant to performance; and, demonstrate through example the conclusions determined by the analysis about apparent compositional techniques in the music.

The superline has one even and one odd coordinate. We consider the Lie superalgebra of contact vector fields on the superline. Its tensor density modules are a one-parameter family of deformations of the natural action on the ring of polynomials on the superline. They are parameterized by a complex number, and they are irreducible when this parameter is not zero. In this dissertation, we describe the annihilating ideals of these representations in the universal enveloping algebra of this Lie superalgebra by providing their generators. We also describe the intersection of all such ideals: the annihilator of the direct sum of the tensor density modules. The annihilating ideal of an irreducible non-zero left module is called a primitive ideal, and the space of all such ideals in the universal enveloping algebra is its primitive spectrum. The primitive spectrum is endowed with the Jacobson topology, which induces a topology on the annihilators of the tensor density modules. We conclude our discussion with a description of the annihilators as a topological space.

Artificial intelligence (AI) and predictive modeling are tools used to diagnose a disease, determine how much a home is worth, estimate insurance risks, and detect fraud. AI and predictive modeling are so ubiquitous that they can be why one gets spam and why spam is automatically deleted. Information science integrates interdisciplinary elements of data-driven, behavioral, design, interpretive, and analytical research methodologies to design and understand interactions between digital media, information systems, and humans. This research focuses on the interaction between humans, AI, and predictive models. This research proposes a theoretical framework and a conceptual research model to understand the antecedents to reliance on AI and predictive modeling. The dissertation follows a traditional format that includes three studies. Study 1 employed a deductive quantitative research approach as a survey to model the relationship between trust in science and reliance on formal news sources. Study 2 employed a deductive quantitative research approach as a survey to understand the impact of framing questions and consider an alternative method of measuring society's reliance on science using predictive models. Study 3 employed a deductive quantitative research approach in the form of a survey to posit a new model based on the first two studies. This …

Antonio María Valencia (1902-1952) was one of the leading Colombian composers, pianists, and educators of his generation. His Dúo en forma de sonata (1926) for violin and piano serves as an early example of the composer's aesthetic. According to the programmatic description he sent to his mother, the Dúo depicts Valencia's "indelible impressions" of his homeland. Through structural and harmonic analysis, I examine the piece in relation to the composer's informal programmatic description. The analysis argues that the work poetically re-creates the landscape of Valencia's birthplace region through an international language, devoid of Colombian folk rhythms and melodies. Valencia proposes a different perspective on Colombian music as an alternative to the use of folk-based music elements that were predominant to Colombian music during his lifetime.

The purpose of this document is to investigate how trumpet students at the University of North Texas experience music performance anxiety and to find out how professors prepare students for controlling music performance anxiety experiences. The interviewees were ten undergraduates and ten graduate students, as well as three trumpet professors who teach at the University of North Texas. The questionnaire responses of the student interviewees were examined, and literature is provided that address the most common performance related psychological and physiological symptoms experienced by the trumpet students. Effective and healthy strategies are discussed that were offered by the trumpet professors, and suggestions are made regarding potential benefits and detriments of trumpet performance anxiety.

There is a lack of anxiety relief methods used in the hospitality workplace. This study examines the effectiveness of two forms of anxiety relief through four different methods. The data collection took place in classroom environments at the University of North Texas and the University of New Orleans, both of which are located in southern USA. The independent variables are the recovery method, the mediator variables are restorativeness and emotional improvement, and the dependent variables are negative job affects, positive job affects, turnover intention, and job commitment. Professors were asked for some time during their lecture to conduct the experiment in a classroom environment during the students' class time. Eight classes were visited, with each class being exposed to a designated anxiety relief method. The anxiety relief methods consisted of using a virtual reality headset with sound, virtual reality headset without sound, nature pictures with sound, and nature pictures without sound. Results of 206 usable surveys indicated virtual reality recovery method evoked higher levels of restorativeness than picture recovery method. Restorativeness partially mediated the effects of positive job affects and job commitment. lastly, emotional improvement partially mediated the effects of negative job affects, positive job affects, and turnover intention.
