Comparative Analysis of the Musical Distortion in Kaikhosru Sorabji’s and Vladimir Horowitz’s Piano Paraphrases Based on Bizet’s Opera Carmen

Comparative Analysis of the Musical Distortion in Kaikhosru Sorabji’s and Vladimir Horowitz’s Piano Paraphrases Based on Bizet’s Opera Carmen

Date: December 2014
Creator: Kim, Mi-Jin
Description: This study focuses on a comparative analysis of two piano paraphrases, Pastiche on Habanera from ‘Carmen’ by Kaikhosru Sorabji and Variations on a Theme from Bizet’s ‘Carmen’ by Vladimir Horowitz. These compositions idiomatically distort the original material in a manner that was not explored up to the moment of their respective conception. They expose each composer’s free compositional approach, reflecting musical freedom rooted in the originality of their musical thinking. The aesthetic uniqueness of these two compositions strongly stimulates and justifies academic interest to explore their technical construction, musical differences, and artistic significance. This study proposes to undertake a comparative study of these two compositions, analyzing (1) aspects of the musical character, which are linked with embellishment, or rearrangement of original material, and (2) differences in performance approach based on recorded examples and critical observations by others of the performances of these works by Sorabji and Horowitz.

Characterization of Ionic Liquid Solvents Using a Temperature Independent, Ion-specific Abraham Parameter Model

Characterization of Ionic Liquid Solvents Using a Temperature Independent, Ion-specific Abraham Parameter Model

Date: December 2014
Creator: Stephens, Timothy W.
Description: Experimental data for the logarithm of the gas-to-ionic liquid partition coefficient (log K) have been compiled from the published literature for over 40 ionic liquids over a wide temperature range. Temperature independent correlations based on the Gibbs free energy equation utilizing known Abraham solvation model parameters have been derived for the prediction of log K for 12 ionic liquids to within a standard deviation of 0.114 log units over a temperature range of over 60 K. Temperature independent log K correlations have also been derived from correlations of molar enthalpies of solvation and molar entropies of solvation, each within standard deviations of 4.044 kJ mol-1 and 5.338 J mol-1 K-1, respectively. In addition, molar enthalpies of solvation and molar entropies of solvation can be predicted from the Abraham coefficients in the temperature independent log K correlations to within similar standard deviations. Temperature independent, ion specific coefficients have been determined for 26 cations and 15 anions for the prediction of log K over a temperature range of at least 60 K to within a standard deviation of 0.159 log units.

Access: Use of this item is restricted to the UNT Community.
Date: August 2014
Creator: Tientong, Jeerapan
Description: The new nickel/layered silicate nanocomposites were electrodeposited from different pHs to study the influence on the metal ions/layered silicate plating solution and on the properties of the deposited films. Nickel/layered silicate nanocomposites were fabricated from citrate bath atacidic pHs (1.6−3.0), from Watts’ type solution (pH ~4-5), and from citrate bath at basic pH (~9). Additionally, the new nickel/molybdenum/layered silicate nanocomposites were electrodeposited from citrate bath at pH 9.5. The silicate, montmorillonite (MMT), was exfoliated by stirring in aqueous solution over 24 hours. The plating solutions were analyzed for zeta potential, particle size, viscosity, and conductivity to investigate the effects of the composition at various pHs. The preferred crystalline orientation and the crystalline size of nickel, nickel/layered silicate, nickel/molybdenum, and nickel/molybdenum/layered silicate films were examined by X-ray diffraction. The microstructure of the coatings and the surface roughness was investigated by scanning electron microscopy and atomic force microscopy. Nickel/molybdenum/layered silicate nanocomposites containing low content of layered silicate (1.0 g/L) had increase 32 % hardness and 22 % Young’s modulus values over the pure nickel/molybdenum alloy films. The potentiodynamic polarization and electrochemical impedance measurements showed that the nickel/molybdenum/layered silicate nanocomposite layers have higher corrosion resistance in 3.5% NaCl compared to the pure alloy ...

An Examination of Text Reflection and Imagery in Zoltán Gárdonyi’s Fünf Lieder Nach Gedichten Von Rainer Maria Rilke

An Examination of Text Reflection and Imagery in Zoltán Gárdonyi’s Fünf Lieder Nach Gedichten Von Rainer Maria Rilke

Date: August 2014
Creator: Beloncik Schantz, Anne
Description: Zoltán Gárdonyi is described as having exemplified “the continuation of the Liszt tradition” in his music; however, since for so much of his compositional life he was forbidden to publish by the Communist government in Hungary due to his connection to the Christian church, he has been largely forgotten. Shortly after the composer’s death in 1986, Gárdonyi’s son, Zsolt (b.1946) began publishing his father’s music in addition to his own. However, the elder Gárdonyi’s works are still not widely known outside Hungary and Germany. Gárdonyi’s ability to support and reflect text musically makes his songs excellent teaching tools and recital repertoire. A characteristic example of this may be found in his Fünf Lieder nach Gedichten von Rainer Maria Rilke. According to his son, Zoltán wrote these songs “in the German romantic tradition (e.g. Brahms) like a mirror for the romantic influenced lyrics.” Examination of the Rilke-Lieder, and of the poems which make up the cycle, demonstrates the composer’s ability to “mirror” text in both general tone and specific idea. Discussion of imagery, textures and sonorities, and elements of harmony, melody and rhythm as they relate to interpretation of the poetry, reveal the depth to which the poetry is embedded in ...

The Measurement of Occupational Identity Among Undergraduate Preservice Music Teachers: a Test Development Study

The Measurement of Occupational Identity Among Undergraduate Preservice Music Teachers: a Test Development Study

Date: August 2014
Creator: Rewolinski, Christine
Description: A large segment of society is either preparing to enter the work force, or is already engaged in some chosen line of work. Preparing to enter the work force takes a considerable amount of time and effort. The decision to follow one career path over countless others may, on the surface, appear to be discretely individual. But when viewed from a sociological perspective, occupational choices are implicitly and explicitly reached through a consensus of contributing factors. Consequently, an occupational identity is not how an individual describes a personal work-related self, but is rather dialectic. It is the merging, albeit, negotiation of viewpoints which causes persons to view themselves in relationship with how others think of them. It is expected that students newly enrolled in music education degree programs will, with time, replace erroneous lay conceptions of music teaching with those presented in curricula and espoused by significant role models. However, the professional socialization process, characteristic of music education degree programs, has not always been successful in transforming students’ personal perspectives of music teaching. This transformation process is critical toward the development of occupational identities that are congruent with school music teaching positions. There has been an established line of research ...

Breaking the Doubler Barrier: Using Sy Brandon’sDivertissement to Demonstrate a Practical Approach to Performing Multiple WoodwindWorks

Breaking the Doubler Barrier: Using Sy Brandon’sDivertissement to Demonstrate a Practical Approach to Performing Multiple WoodwindWorks

Date: December 2014
Creator: Levels, Brian Eugene
Description: Multiple woodwind training is ideal for securing certain types of employment; however, with so many different instruments, performance standards on each are difficult to maintain. Furthermore, for many multiple woodwind players, proficiency on all woodwinds ceases to be a top priority after graduation, even though they continue to market themselves as highly proficient on all of these instruments. The problem for most begins with what it means to be proficient on each instrument. The technical demands of multiple woodwind performance vary widely, but often a performance calls for complete proficiency on a variety of instruments. Multiple woodwind players who lack in professional level proficiency damage the credibility of the field and jeopardize employment opportunities for others. This study aims to address the common problems involving proficiency and to help multiple woodwind players, band directors, and doublers become familiar with and overcome these common pitfalls. Sy Brandon’s Divertissement provides an outstanding platform to address problems and provide solutions for multiple wind players, band directors, and doublers. This dissertation serves as a multiple woodwind specialist’s resource for maximum efficiency in learning and playing repertoire that involves multiple woodwinds, such as musicals, and other multiple woodwind genres.

Measuring Teaching Effectiveness Using Value-added and Observation Rubric Scores

Measuring Teaching Effectiveness Using Value-added and Observation Rubric Scores

Date: December 2014
Creator: McKenzie, Andrew
Description: This mixed-methods study examined the extent to which teacher performance and student performance measures correlated, and to understand which specific practices of mathematics teachers in Grades 3-5 related to student performance. Research was conducted at five elementary schools in a large, urban north Texas school district. Data sources included component scores and recorded evidence from observation rubrics, interviews with campus administrators, and value-added modeling (VAM) student growth scores. Findings indicated a modest relationship between teacher performance levels and student performance levels. Lack of access to individual teacher VAM data, per district policy, might have impacted the strength of the relationship. Interviews with administrators and an examination of the evidence cited in the observation rubrics identified specific practices associated with highly rated mathematics teaching. Differences in administrators’ experience levels with both mathematics instruction and the observation instrument might have influenced rubric scores and the level of specificity shown in evidence statements.

Studies of Charged Particle Dynamics for Antihydrogen Synthesis

Studies of Charged Particle Dynamics for Antihydrogen Synthesis

Date: December 2014
Creator: Correa, Jose Ricardo
Description: Synthesis and capture of antihydrogen in controlled laboratory conditions will enable precise studies of neutral antimatter. The work presented deals with some of the physics pertinent to manipulating charged antiparticles in order to create neutral antimatter, and may be applicable to other scenarios of plasma confinement and charged particle interaction. The topics covered include the electrostatic confinement of a reflecting ion beam and the transverse confinement of an ion beam in a purely electrostatic configuration; the charge sign effect on the Coulomb logarithm for a two component (e.g., antihydrogen) plasma in a Penning trap as well as the collisional scattering for binary Coulomb interactions that are cut off at a distance different than the Debye length; and the formation of magnetobound positronium and protonium.

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Date: August 2014
Creator: Herauf, Todd J.
Description: In a 3-year timeframe, nearly 800 student negligence suits were filed, and most involved some claim of personal injury. Despite heightened public attention of negligence lawsuits against school districts and their employees, an empirical study of court decisions revealed that the volume of litigation against school districts remained steady from 1990 to 2005, the majority of cases were ruled in favor of the school district employees, and government and official immunity were most often the basis for these rulings. Researchers have concluded that immunity laws are strong in the United States, although they vary by state in their application. However, a primary recommendation was that, because of the misconception of a lack of immunity for public school employees, a comprehensive study on governmental and official immunity is needed. This dissertation employed legal research, analysis, and methodology to engage in a comprehensive investigation of teacher immunity in the four southern states of Texas, Oklahoma, Mississippi, and New Mexico. Of central concern to this dissertation was the Tort Claims Act of 1978 from the State of New Mexico. The Tort Claims Act is the vehicle by which immunity is granted to public school employees. Court findings over the last 35 years point ...
