This lecture recital seeks to prove that Sergei Taneyev's only piano concerto is a valuable addition to the piano concerto repertoire for historical and theoretical examination. Taneyev's biographical background proves he was one of the major figures in Russian musical life during the late nineteenth century. For one who had such an important role in music history, it is an unfortunate that his music has not been popular. Through letters to contemporary composers and friends, Taneyev's master teacher Tchaikovsky revealed why his music and piano concerto were not as popular as they should have been. This lecture recital examines Taneyev's compositional style and illustrates his influence in the works of his famous student Sergei Rachmaninoff through examples from Taneyev's Piano Concerto in E-flat Major and Rachmaninoff's Piano Concerto No. 2. Taneyev's Piano Concerto and Tchaikovsky's Piano Concerto No. 1 have both similarities and differences that resulted from the composers' close relationship. Letters between the teacher and student enlighten readers to the compositional process of the two piano concertos and demonstrates the value of Taneyev's Piano Concerto. A detailed theoretical analysis is included in this dissertation. The principal themes and motifs are presented with a detailed analysis of the structure of …

Among the commercial aluminum alloys, aluminum 319 (Al-7wt%Si-4wt%Cu) type alloys are popularly used in automobile engine parts. These alloys have good casting characteristics and excellent mechanical properties resulting from a suitable heat treatment. To get a high strength in the 319 type alloys, grain refining, reducing the porosity, solid solution hardening, and precipitation hardening are preferred. All experimental variables such as solidification condition, composition, and heat treatment are influence on the precipitation behavior; however, precipitation hardening is the most significant because excess alloying elements from supersaturated solid solution form fine particles which act as obstacles to dislocation movement. The challenges of the 319 type alloys arise due to small size of precipitate and complex aging response caused by multi components. It is important to determine the chemical composition, crystal structure, and orientation relationship as well as precipitate morphology in order to understand the precipitation behavior and strengthening mechanism. In this study, the mechanical properties and microstructure were investigated using transmission electron microscopy and three dimensional atom probe tomography. The Mn and Mg effects on the microstructure and mechanical properties are discussed with crystallographic study on the iron intermetallic phases. The microstructural evolution and nucleation study on the precipitates in the …

This dissertation examined the impact of Medicare Plan D on medication compliance in Medicare beneficiaries at University of Texas Health Center at Tyler, TX. Data were collected before and after the implementation of Plan D. The impacts of various types of benefits, such as private insurance, employer insurance and pharmacy assistance programs were evaluated in terms of impact on drug compliance. Medication compliance was found to increase in those respondents without Plan D. Plan D was found to be a predictor of those who spent less on basics in order to buy medications. Although compliance increased in general, these increases could not be attributed to the acquisition of a Plan D policy.

Reality TV is the most popular genre of television programming today. The number of reality television shows has grown exponentially over the last fifteen years since the premier of The Real World in 1992. Although reality TV uses styles similar to those used in documentary film, the “reality” of the shows is questioned by critics and viewers alike. The current study focuses on the “reality” that is presented to viewers and how that “reality” is created and may differ from what the participants of the shows experience. I appeared on two reality shows, Faking It and That's Clever, and learned a great deal as a participant observer. Within the study, I outline my experience and demonstrate how editing changed the reality I experienced into what was presented to the viewers. O'Connor's (1996) representation context web serves as a model for the realities created through reality television. People derive various benefits from watching reality TV. Besides the obvious entertainment value of reality TV, viewers also gather information via this type of programming. Viewers want to see real people on television reacting to unusual circumstances without the use of scripts. By surveying reality TV show viewers and participants, this study gives insight …

The interaction among firms in the supply chain is necessary for business process execution and relationship success. One phenomenon of great significance to buyer-supplier relationships is opportunism. Opportunism is defined as behavior that is self-interest seeking with guile. It is manifested in behaviors such as stealing, cheating, dishonesty, and withholding information. Opportunism negatively impacts relational exchange tenets such as trust, commitment, cooperation, and satisfaction. Furthermore, perceptions of opportunism negatively affect firm performance. In lieu of the known negative effects of opportunistic behavior on buyer-supplier relationships, why do agents continue to engage in opportunistic tactics with their exchange partners? A comprehensive examination is necessary in order to understand why sourcing professionals engage in acts of opportunism. Understanding why opportunism occurs will reveal how to deter it, and this remains a gap in the literature. Based on theories in economics, marketing channels, supply chain management, decision science, and psychology, a comprehensive model tested a set of factors hypothesized to drive the use of opportunistic tactics. Factors include buyer-supplier relationship-specific factors, environmental factors, individual personality-related factors, and situational factors. Data was collected via internet survey of sourcing professionals from private industry and government agencies. Common to many studies of ethics, respondents made choices …

The two major research questions were: “What is the current status of 20 prominent piano pedagogy programs?” and “what is the vision of an ideal future piano pedagogy program from the perspective of 20 piano pedagogy leaders?” Subjects were the leaders of the top 20 US university piano pedagogy programs. A survey study with interview questions was used as the instrument for the study. The results showed that faculty, curriculum, and teacher training were three top factors that contributed to the quality of the programs. Most interviewed subjects held a doctoral degree in music. The curricular content and degree options were diverse across the selected programs. The content of teacher training included private and group teaching. The perceived best qualifications of a piano pedagogy instructor were to have a balanced education. Most programs had small or little to no budget, however, the preparatory program was perceived to be an enhancement to teacher training program finances. The greatest challenges were faculty acquisition and financial limitations. Gaining more money was the most common improvement priority for programs. To envision an ideal future piano pedagogy program, most leaders stated that an ideal program should contain encourage: (1) collaborating with other divisions' faculty members …

The present study was a retrospective chart review (N=128) that investigated the efficacy of profiles derived from the three factors of the Eating Inventory® test (EI) - cognitive restraint, disinhibition, and hunger - to predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this population. Based on restraint theory, 7 profiles (high CR, super high CR, high D, super high D, high H, super high H, and null) were derived from the raw scores on the subscales of the EI and tested for weight loss predictive ability using direct logistic regression. Results were mixed with high CR, super high CR, and null profiles accurately predicting successful weight loss. Raw scores on the three factors (cognitive restraint, disinhibition, and hunger) were tested individually for predictive ability using direct logistic regression. Overall results indicated that the profile model accurately predicted more cases than the general factor model. This study significantly contributes to both the bariatric presurgical assessment literature and the restraint theory literature. Suggestions for future research are offered.

Balakirev's two early piano and orchestra works, Grande Fantaisie on Russian Folk Songs and Concerto Op. 1 in F# Minor, were composed in the middle of the nineteenth century when in Russia there were no particularly important works for piano and orchestra. Balakirev was still a teenager when he wrote these two pieces and unfortunately both remained unfinished. However the beauty and remarkable compositional achievement of these works should be highly recognized. There are six chapters in this essay. The general background, purpose and the state of research are discussed in the first chapter. The second chapter presents Balakirev's biographical information and the overview of his works for piano and orchestra is stated in Chapter III. Individual works, Grande Fantaisie and Concerto in F# Minor are discussed in the chapters IV and V, which including discussing compositional background, analysis and diagram of structural schemes. The last chapter concludes with Balakirev's contribution to Russian music and the development of the Russian concerto coming into its own. It deals particularly with Balakirev's approach to folk songs, which gives the concerto a unique Russian aesthetic, in addition to his ability to write in the European tradition.

The aspiration of this dissertation is to bring forth the significance of Shostakovich's Piano Sonata Op.12. This sonata is a hybrid of the German musical tradition, Russian Modernism, and Liszt's thematic transformation technique. It demonstrates Shostakovich's highly intellectual compositional skills influenced by the education that he received at St. Petersburg Conservatory as well as the exposure to modern music in the 1920s. This dissertation discusses composition techniques, such as the harmonic piers adapted from Alexander Scriabin, neighboring-tone technique, which involves the application of semitone cell throughout the piece, as well as the technique of thematic transformation borrowed from Liszt. These all come together by Shostakovich's design in the most controversial sonata form. The Piano Sonata Op.12 also sheds light on Shostakovich's early compositional style and proves its contribution to the evolution of sonata genre in the twentieth-century.

The Octuor pour instruments a vents (or Octet), written in 1922-1923 by Igor Stravinsky, is a piece in three movements for a curious assortment of instruments: two trumpets, two trombones, flute, clarinet and two bassoons. It is one of four influential chamber works for winds by Stravinsky to include trumpet. Of these pieces, the Octet contains the fewest number of players but is no less complex and important in Stravinsky's oeuvre. The Octet helped mark the beginning of the neoclassical period in twentieth-century music. Chapter 2 examines the life and musical background of the composer. It also reveals the history surrounding the origin of the Octet and its role in neoclassicism. Chapter 3 discusses the role of the Octet in the wind ensemble and orchestral repertoire, and includes a representative performance history, including the premiere. Chapter 4 provides analytical insights into the construction and format of the piece. Chapter 5 provides suggestions regarding style in Stravinsky's music, including interviews with important figures in the trumpet world. Chapter 6 concludes the guide with specific suggestions regarding preparation and performance of the Octet.

The purpose of this study was to conduct a survey to identify the beliefs and practices of conservative Protestant parents, which assisted in clarifying the assertions in the current literature regarding conservative Protestant parenting. Additionally, this researcher sought to determine the applicability of child parent relationship therapy (CPRT), a filial therapy model based upon the principles of child centered play therapy, for conservative Protestant parents by ascertaining the need for cultural modifications. Beliefs and practices of conservative Protestants were measured using the Protestant Parenting Inventory (PPI), an original instrument developed through a series of focus groups and pilot testings. The population comprised 148 mothers and fathers from 4 Southern Baptist churches in and around the Dallas/Fort Worth metroplex. Exploratory factor analysis was applied to the data in order to increase internal consistency estimates and percent of explained variance. Criterion coding of demographic data allowed a multiple regression analysis to determine which demographic variables were significant predictors of participant responses on the PPI. Descriptive statistics allowed the researcher to investigate the compatibility of conservative Protestants and CPRT. Results of this study both confirm and refute past findings regarding conservative Protestants. Results also revealed the need for some cultural modifications to CPRT …

This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I end-of-course examination, given as a district option to Algebra I students, and student final course grades as determined by classroom teachers. The study compared students' performance in these three areas during the 2004-2005 academic year in one suburban school district in North Texas. The study considers the type of schedule, either traditional or 8-block, between students in teachers' classes who teach the same course on both schedules concurrently. This study also investigates a qualitative aspect by including a short opinion survey of teachers' perceptions regarding student academic performance, teacher satisfaction and retention, and the ability to accomplish curricular goals. Findings from this research suggest course schedule does not have significant effects on student academic performance as measured using analyses of covariance comparisons with a 0.05 alpha-level, leading to the conclusion that a particular course schedule does not adversely impact student performance on academic measures. However, in some comparisons conducted within the course of the …

The presence of deposits on the secondary side of pressurized water reactor (PWR) steam generator systems is one of the main contributors to the high maintenance costs of these generators. Formation and transport of corrosion products formed due to the presence of impurities, metals and metallic oxides in the secondary side of the steam generator units result in formation of deposits. This research deals with understanding the deposit formation and characterization of deposits by studying the samples collected from different units in secondary side system at Comanche Peak Steam Electric Station (CPSES). Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) have been used for studying the phases, morphologies and compositions of the iron oxides formed at Unit 1 and Unit 2 of secondary side of steamgenerator systems. Hematite and magnetite were found to be the dominant phases of iron oxides present in the units. Fe, Cr, O, Ni, Si, Cl and Cu were found in samples collected from both the units. A qualitative method was developed to differentiate iron oxides using laser induced breakdown spectroscopy (LIBS) based on temporal response of iron oxides to a high power laser beam. A quantitative FTIR technique was …

The state of Texas passed the Student Success Initiative (SSI) in 1999 which requires all 3rd graders to pass the reading portion of the Texas Assessment of Knowledge and Skills (TAKS) test to be promoted to the 4th grade, and for 5th graders to pass the reading and math portions of the TAKS test to be promoted to the 6th grade. Beginning in spring 2008, 8th graders will also need to pass the reading and math portions of the TAKS test to be promoted to the 9th grade. The purpose of this study was to examine the academic performance of 3rd and 5th grade students who did not meet the passing standard on the TAKS test and were retained during the 2005-2006 school year. The population of this study included 33 3rd graders and 49 5th graders who were retained during the 2005-2006 school year due to not meeting the promotion requirements of the SSI. There was also a second population of 49 5th graders who were retained in 3rd grade during the 2003-2004 school year due to not meeting the promotion requirements of the SSI. These students were enrolled in the 5th grade for the first time during the …

In recent years scholars have begun to re-evaluate the works, writings, and life of Robert Schumann (1810-1856). One of the primary issues in this ongoing re-evaluation is a reassessment of the composer's late works (roughly defined as those written after 1845). Until recently, the last eight years of Schumann's creative life and the works he composed at that time either have been ignored or critiqued under an image of an illness that had caused periodic breakdowns. Schumann's late works show how his culture and the artists communicating within that culture were transformed from the beginning to the middle of the nineteenth century. These late works, therefore, should be viewed in the context of Schumann's output as a whole and in regard to their contributions to nineteenth-century society. Schumann's contributions, specifically to the genre of the song cycle from 1849 to 1852, are among his late compositional works that still await full reconsideration. A topical study, focusing on three themes of selections from his twenty-three late cycles, will provide a critical evaluation of Schumann's compositional output in the genre of the song cycle. First, Schumann's political voice will be examined. The political events that led to the mid-nineteenth-century revolutions inspired crucial …

Layered double hydroxides (LDH) have been principally known as anion-exchanging, clay-like materials for several decades, and continues to be the main driving force for current and future research. The chemical interactions of LDH, with transition metallocyanides, have been a popular topic of investigation for many years, partly due to the use of powder x-ray diffraction and infrared spectroscopy as the main characterization tools. Each transition metallocyanide has a characteristic infrared stretching frequency that can be easily observed, and their respective sizes can be observed while intercalated within the interlayer of the LDH. The ability of LDH to incorporate metal cations or any ions/molecules/complexes, that have a postive charge, have not been previously investigated, mainly due to the chemical and physical nature of LDH. The possibility of cationic incorporation with LDH would most likely occur by surface adsorption, lattice metal replacement, or by intercalation into the LDH interlayers. Although infrared spectroscopy finds it main use through the identification of the anions incorporated with LDH, it can also be used to study and identify the various active and inactive bending and stretching modes that the metal hydroxide layers have.

Admissions processes for health professions programs result in students entering these programs academically homogeneous. Yet some students have great difficulty with the programs. Research has shown a limited ability of traditional academic indicators to predict successful outcomes for health professions education. The purpose of this study was to examine the relationship between learning motivation and academic outcomes for students in health professions programs. The Modified Archer Health Professions Motivation Scale (MAHPMS) and a demographic survey were administered at orientation to 131 medical and 29 physician assistant students at the University of North Texas Health Science Center in the fall of 2005. At the end of the semester, the same version of the MAHPMS was administered, and final course grades and semester averages were collected. Descriptive statistics were analyzed for all the study variables. Analysis of variance was utilized to examine within subjects and between subjects differences for the learning motivation scores among programs and demographic categories. Linear regression analyses were used to determine the relationship between learning motivation scores and end-of-semester grades. And finally, logistic regression was performed to explore the ability of the motivation scores to predict academically high-risk students. Approximately three-fourths of the students indicated a preference for …

This study examined the current status of schoolwide positive behavior support efforts in Texas. The study specifically (a) examined the impact of statewide positive behavior interventions and supports (PBIS) training on the rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions of public schools in Texas; (b) investigated the overall effectiveness of schoolwide positive behavior support; and (c) determined the differences between rates of discipline records, in-school ¬suspensions, out-¬of¬-school suspensions, disciplinary alternative education placements, and expulsions in schools participating in the Texas Behavior Support Initiative (TBSI): Schoolwide PBS Project when compared with matching schools who did not participate in the project. This study demonstrated that schools can significantly reduce problem behavior in their schools when implementing PBIS with fidelity. Creating effective systems of PBIS required training, coaching, and on¬site technical assistance by trained and experienced PBIS facilitators.

In 2005, composer Susan Botti won the coveted Prix de Rome in musical composition and spent eleven months in residency at the American Academy in Rome. That same year, the University of Michigan Wind Symphony, under the direction of Michael Haithcock, premiered her exciting new work Cosmosis at the College Band Directors National Association Conference in New York City. The bi-annual conference is a venue for the premiere of new works for wind ensembles and bands, and the 2005 conference saw the world premiere of nine works for winds and percussion, many of which were performed in the legendary Carnegie Hall. What made the debut performance of Cosmosis exciting and notable was the composer's own appearance as soprano soloist, and the inclusion of a chorus of women augmenting the ensemble of winds and percussion. Such a combination of elements is unique, and created a fresh and powerful sonority. Botti's inventive approach to composition has expanded the repertoire for both women's chorus and wind ensemble with this distinctive work. This study is intended to serve as a guide to the study and performance of Cosmosis. The information provides a detailed examination of the work from its conception to its premiere performance. …

The barrier properties of polymers are a significant factor in determining the shelf or device lifetime in polymer packaging. Nanocomposites developed from the dispersion of nanometer thick platelets into a host polymer matrix have shown much promise. The magnitude of the benefit on permeability has been different depending on the polymer investigated or the degree of dispersion of the platelet in the polymer. In this dissertation, the effect of density changes in the bulk and at the polymer-platelet interface on permeability of polymer nanocomposites is investigated. Nanocomposites of nylon, PET, and PEN were processed by extrusion. Montmorillonite layered silicate (MLS) in a range of concentrations from 1 to 5% was blended with all three resins. Dispersion of the MLS in the matrix was investigated by using one or a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Variation in bulk density via crystallization was analyzed using differential scanning calorimetry (DSC) and polarized optical microscopy. Interfacial densification was investigated using force modulation atomic force microscopy (AFM) and ellipsometry. Mechanical properties are reported. Permeability of all films was measured in an in-house built permeability measurement system. The effect of polymer orientation and induced defects on permeability …

A series of computational studies were carried out on Group 14 (C, Si and Ge) elements in organometallic and biological compounds. Theoretical studies on classical and H-bridged A3H3+ (A=C, Si and Ge) as p ligands with different organometallic fragments at B3LYP and B3P86 level reveal a reverse charge transfer from ligand to metal in Si and Ge complexes whereas in C complexes there is a small charge transfer from metal to ligand. The H-bridged complexes are more stable than the complexes based on Si3H3+ and Ge3H3+ ligands with terminal hydrogens. The stability of the bridged systems increases from Si to Ge. Corrective scale factors for computed harmonic CºO vibrational frequencies for 31 organometallic complexes have been determined at the HF and B3LYP levels. The scaled B3LYP frequencies exhibit a greater reliability than do HF frequencies. Experimental data have shown that Si/Ge-substituted decapeptides are advantageous over their C analog in vitro and in vivo studies in modern hormone therapy. A computational investigation was carried out on the synthesized decapeptides focusing on position 5 containing Si and Ge. The results have shown that there are some differences in C, Si and Ge-containing analogs. However, further investigations are needed to elucidate the observed …

Interactional and contextual models have been conceptually proposed in understanding parental influences on children. Yet, empirical model testing has been limited. The purpose of this exploratory study was to investigate the direct and indirect effects of parenting style on child social competence using structural equation modeling in a sample of 544 Chinese families with 6-9 years old children, mainly singleton, residing in Nanjing, China. Five latent models were tested: (a) the direct model between parenting style and child social competence, (b) child temperament as a moderator, (c) parent-child relationship as a mediator, (d) the interaction model between parenting style and family functioning, and (e) bidirectional models of parenting style concurrently with parent-child relationship, and family functioning predicting child social competence. Findings showed: (a) The direct relationship between parenting style and child social competence was significant in both parents with authoritative parenting style on the positive direction, whereas authoritarian and permissive parenting styles on the negative direction; (b) child temperament did not moderate parenting style on child social competence; (c) father-child relationship mediated paternal parenting style on child social competence, whereas maternal parenting style did not; (d) family functioning neither moderated nor mediated the relationship between parenting style and child social …

The role of social capital in forming organizational commitment is the focus of this research. Organizational social capital is the idea that social relationships have value in the organization. The theoretical framework is based on Kanter's (1993) structure of organizational commitment. This research views the structure within organizations based on global empowerment, job satisfaction, organizational commitment, and social capital. In addition, the role that race, income, and education affect the organizational structure is also taken into account. The organizational configuration was assembled using a structural equation model with latent variables employing a sample of 235 certified nurse aides. The sample was collected from 10 nursing homes in the Dallas-Ft.Worth metropolitan area. It was expected that Kanter's general format is reestablished within the sample. In fact, the study found that empowerment significantly influences job satisfaction. In turn, job satisfaction does foster organizational commitment. Although Kanter's original thesis was supported in this analysis, it was also determined that social capital plays a significant mediating role in creating organizational commitment. Furthermore, this research indicates that social capital alone can create organizational commitment. Thus, in conclusion, this research builds on Kanter's original idea and argues that organizational commitment is based on job satisfaction, global …

This is a case study of the historical development of a private Christian faith-based school of higher education in post-Soviet Russia from its conception in 1990 until 2006. This bi-national school was founded as the Russian-American Christian University (RACU) in 1996. In 2003, RACU was accredited by the Russian Ministry of Education under the name Russko-Americansky Christiansky Institute. RACU offers two state-accredited undergraduate academic programs: 1) business and economics, and 2) social work. RACU also offers a major in English language and literature. The academic model of RACU was designed according to the traditional American Christian liberal arts model and adapted to Russian higher education system. The study documents the founding, vision, and growth of RACU. It provides insight into the academic, organizational, and campus life of RACU. The study led to the creation of an operational framework of the historical development of RACU. The study also provides recommendations for the development of new Christian liberal arts colleges and universities based on the experience and the underlying structure of RACU.
