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 …

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 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.

The Pueblo III period marks a critical shift in settlement location of Ancestral Puebloan people within the Mesa Verde region. Community centers during the Pueblo I and Pueblo II periods were built on mesa tops, whereas canyon-rims and alcoves became the preferred settlement location during the Pueblo III period. Beginning in the Pueblo I period, community centers consisted of linear roomblock villages. By the late Pueblo II period great house community centers influenced by the Chaco culture system spanned the Mesa Verde region. The Pueblo III period hallmarks the transition to canyon-rim villages and cliff dwellings. The location of these Pueblo III centers is thought to be related to the need for a defensive position on the landscape, and access to water sources. This shift in settlement locations undoubtedly led to change in the access to resources, such as water, arable farmland, and wild food plants and game. This study aims to evaluate whether the change in community center location impacted the accessibility to arable farmland and water sources immediately available to Ancestral Puebloan people throughout time. Specifically, several variables related to farming potential and hydrologic potential, including soil type, soil moisture, elevation, cropland suitability, distance to water sources, drainage …

Students' self-determination (SD) can positively influence their ability to make choices in planning for their future. The current study is a preliminary validity study on the most recent 21-item version of Shogren and Wehmeyer's Self-Determination Inventory: Student Report (SDI-SR). The SDI-SR was administered to 316 students (ages 13-22) and results were examined with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results of the EFA on a 7-factor solution (TLI = 0.97; RMSEA = 0.04; SRMR = 0.02) aligned with the theoretical basis for the SDI:SR as well as results for the 7-factor CFA using simulated data (TLI = 0.913; RMSEA = 0.047; SRMR = 0.072 and CFI = 0.931); however, the CFA 7-factor solution results on the present study data were slightly lower than what is considered acceptable model fit (TLI = 0.883; RMSEA = 0.04; RMSR = 0.047). These results combined suggest that theory-based 7-factor solution does capture seven latent constructs in this data. A CFA was also conducted with a 5-factor structure based on factor loading from an EFA using the present research data resulting in a better model fit (TLI = 0.912; RMSEA = .075; SRMR = 0.046; and CFI = 0.940) as well as …

The direct epitaxial growth of multilayer BN by atomic layer deposition is of critical significance forfo two-dimensional device applications. X-ray photoelectron spectroscopy (XPS) and low energy electron diffraction (LEED) demonstrate layer-by-layer BN epitaxy on two different substrates. One substrate was a monolayer of RuO2(110) formed on a Ru(0001) substrate, the other was an atomically clean Ni(111) single crystal. Growth was accomplished atomic layer deposition (ALD) cycles of BCl3/NH3 at 600 K substrate temperature and subsequent annealing in ultrahigh vacuum (UHV). This yielded stoichiometric BN layers, and an average BN film thickness linearly proportional to the number of BCl3/NH3 cycles. The BN(0001)/RuO2(110) interface had negligible charge transfer or band bending as indicated by XPS and LEED data indicate a 30° rotation between the coincident BN and oxide lattices. The atomic layer epitaxy of BN on an oxide surface suggests new routes to the direct growth and integration of graphene and BN with industrially important substrates, including Si(100). XPS and LEED indicated epitaxial deposition of h-BN(0001) on the Ni(111) single crystal by ALD, and subsequent epitaxially aligned graphene was deposited by chemical vapor deposition (CVD) of ethylene at 1000 K. Direct multilayer, in situ growth of h-BN on magnetic substrates such as …

This thesis attempts to prove the significance of the relationship between the United States and Australia, and how their similar cultures and experiences assisted creating that shared bond throughout the twentieth century. Chapter 2 examines the effects of the Cold War on both the United States and Australia, as well as their growing relationship during that period. There is some backtracking chronologically in order to make connections to important historical legacies such as the ANZAC Legend and settlement on the periphery of their respective societies. Then the first half of chapter 3 delves into the Vietnam War by examining the interactions of the American support unit, the 11th Combat Aviation Battalion, a helicopter unit that includes transports and gunships. Afterwards, the latter half of chapter 3 examines the Australians' after-action reports to better understand their tactical and operational methods. Finally, chapter 4 provides an overview of Australian and American interactions between the advisers and the Vietnamese, as well as their attitudes towards the end of the war and the withdrawal from Vietnam. The conclusion summarizes the significance of the thesis by reemphasizing the significance of US-Australian interactions in the twentieth century and the importance of continued studies on this topic …

Complimentary and alternate medicine, especially Ayurveda is gaining popularity in United States. However, there are various barriers that people face in adopting Ayurvedic practices into their lives and making cultural, familial and societal changes to better their health. This research explores these relationships and barriers behind why some people adopt and are able/unable to sustain Ayurvedic practices in the presence of traditional bio-medicine.

Edge computing and CAV (Connected Autonomous Vehicle) fields can work as a team. With the short latency and high responsiveness of edge computing, it is a better fit than cloud computing in the CAV field. Moreover, containerized applications are getting rid of the annoying procedures for setting the required environment. So that deployment of applications on new machines is much more user-friendly than before. Therefore, this paper proposes a framework developed for the CAV edge computing scenario. This framework consists of various programs written in different languages. The framework uses Docker technology to containerize these applications so that the deployment could be simple and easy. This framework consists of two parts. One is for the vehicle on-board unit, which exposes data to the closest edge device and receives the output generated by the edge device. Another is for the edge device, which is responsible for collecting and processing big load of data and broadcasting output to vehicles. So the vehicle does not need to perform the heavyweight tasks that could drain up the limited power.

In 1964, Benjamin Britten met the multi-instrumentalist twins Zoltán and Gábor Jeney while traveling in Budapest. At their behest, Britten composed Gemini Variations: Twelve Variations and Fugue on an Epigram by Kodály, a work which exploited the brothers' abilities on multiple instruments: Zoltán on flute and piano, and Gábor on violin and piano. In foreseeing the difficulties of programming this work, Britten simultaneously arranged a version for four players: flute, violin, and four-hand piano, eliminating the need for switching instruments. Despite this arrangement, as well as a very public and highly anticipated premiere at the Aldeburgh Festival in 1965, Gemini Variations has remained neglected by performers and scholars alike. This document serves to 1) promote a work that can justifiably be considered as part of the chamber music repertoire involving flute; 2) advocate for its musical merit and appropriateness for chamber music concerts made up of more traditional groups of players; 3) compare the two-player and four-player versions Britten wrote; and 4) explore the likely reasons why a piece by one of the most celebrated composers of the twentieth century has remained largely ignored for over fifty years.

In this paper, I explore the early musical language of McCoy Tyner. Today, Tyner is recognized mostly for his use of quartal harmony and pentatonic scales despite having made recordings in his early career that reflect a more mainstream approach. In an effort to expand how Tyner is represented, I argue that Tyner's early style was characterized by a graceful balance of tradition and innovation, a masterful blend of bebop syntax with pentatonic melodies and quartal harmonies. The recordings that I analyze and discuss are: "Effendi," "Cousin Mary," and "Newport Romp." I transcribed and analyzed selected portions of these recordings in order to better understand his early musical language as a soloist from 1962 to 1963. A portion of this paper is focused on the early reception of Tyner, which acknowledged him as an accomplished mainstream player with a firm grasp of the jazz tradition. Ultimately, my analysis shows that Tyner's early style was a balance of tradition and innovation, incorporating bebop syntax, pentatonic melodies, and quartal harmonies.

When Czech composer Bedřich Smetana's opera The Bartered Bride received its American premiere at the Metropolitan Opera in February 1909, New York music critics published positive reviews which displayed a great fascination with the many "Bohemian" aspects of the production. However, certain comments or language used by some critics indicate that American opinions of the Czech people were less than positive. After Czechs began immigrating to America en masse in 1848, already-established American citizens developed skewed cultural perceptions of the Czech people, established negative stereotypes, and propagated their opinions in various forms of press throughout the nation. Despite a general dislike of the Czechs, reviewers revered The Bartered Bride and praised its many authentic "Bohemian" qualities. This research explores the idea of a paradoxical cultural phenomenon in which the prejudice against Czech people did not fully cross over into the musical sphere. Instead, appreciation for Czech music and musicians may have trumped any such negative opinions and authentic Czech productions such as The Bartered Bride may have been considered a novelty in the eyes of early twentieth-century New Yorkers.

"It Follows" (2014), written and directed by David Robert Mitchell, premiered at the Cannes Film Festival in 2014. It chronicles the story of Jay, a college student who contracts a curse through sexual intercourse. The curse manifests itself as a human whom only the infected persons can see, always following at a walking pace, and determined to kill if it catches up. This thesis demonstrates the score's crucial role in establishing affect, setting, and character in a film with sparse dialogue and a silent monster. Moreover, the score creates a sense of the uncanny by complicating the binary between music and sound effect and fulfills the need to create dread without resorting to the loud or sudden sounds traditionally heard in horror films. The score's composer, Richard Vreeland, achieves this effect by drawing on both classical film scoring techniques as well as more modern horror scoring styles. It is this interaction between styles that enhances the viewers' experience of dread and horror in the film. This thesis analyzes how Vreeland's score for "It Follows" exploits the poetics of the fantastical gap, of the uncanny, and of musical semiosis. I primarily focus on the "Heels" theme and use of drones in …

This dissertation aims to address the pedagogical gap in introductory material for contemporary clarinet instruction. Through examining the most prominent contemporary methods for the clarinet, the pedagogical gap is highlighted, particularly regarding material aimed at newcomers and early undergraduate students. To address these needs, a new collection of etudes is proposed, introducing extended techniques and contemporary notation for newcomers to modern music.

This research comprised a secondary study using the National Longitudinal Study of Adolescent Health restricted data set to examine the buffering effects of religiosity on adolescent alcohol coping following victimization within the context of Agnew's general stain theory. Its purpose was to determine if religiosity buffered the effects of alcohol abuse coping following victimization for native-born and foreign-born non-Hispanic adolescents, and was designed as a follow-up research study to similarly replicate a prior study limited to native-born and foreign-born Hispanic adolescents. This study's findings were consistent with prior research that higher religiosity was generally predictive of lower levels of alcohol abuse. However, in the presence of violent victimization, religiosity did not buffer later increased alcohol abuse coping for non-Hispanic adolescents. Native-born religiously oriented adolescents were as likely to abuse alcohol following violent victimization as their native-born non-religious peers. Foreign-born religiously oriented versus non-religiously-oriented adolescents did not have statistically significant different outcomes on later alcohol abuse following victimization. Foreign-born non-Hispanic adolescents as a group appeared generally insensitive to victimization strain as measured by alcohol abuse coping. An important outcome of this study was the collateral finding that being Catholic substantially increased the likelihood of later alcohol abuse for both native-born and …

This dissertation examines a recent work for flute and piano, Here Everything Shines, by a living composer, Charlotte Bray, including a study, analysis and performance guide. The composition was largely inspired by the late Cape Verdean singer Cesária Évora and her song Petit Pays. My research explores the influence of Évora's song on Here Everything Shines, including the melodic development, tonal center, style and freedom of her singing and the impact the song has on a performer's interpretation of Here Everything Shines. The study examines the text of the song, the emotions evoked and reflects on the compositional elements in Here Everything Shines. Originally written for flute and guitar and commissioned by Tom Kerstens for International Guitar Foundation, Here Everything Shines was published in 2015. Bray transcribed it for violin and piano at request of Darragh Morgan and Mary Dullea and subsequently for flute and piano at my request. This dissertation compares the three versions for flute and guitar, violin and piano, and flute and piano and examines the variations between flute and violin as well as guitar and piano parts. The performance guide includes the composer's input on both interpretation and implementation of her ideas throughout the work.

A collection of short fiction stories that fixate on the role of the strange and the imagined.
