Johannes Brahms's Ein deutsches Requiem: A Comparison of the Reduced Orchestration Techniques in Joachim Linckelmann's Chamber Ensemble Version to Brahms's Four-Hand Piano Version
Recognizing the challenges small groups have to program a major work, in 2010, Joachim Linckelmann created a chamber ensemble arrangement of Johannes Brahms's "Ein deutsches Requiem." In 1869, J.M. Reiter-Biedermann published Brahms's four-hand piano arrangement of "Ein deutsches Requiem." Brahms's arrangement serves as an excellent comparison to the chamber ensemble version by Linckelmann, since it can be assumed that Brahms chose to highlight and focus on the parts he deemed the most important. This study was a comparative analysis of the two arrangements and was completed in three stages. The first stage documented every significant change in Joachim Linckelmann's recent chamber arrangement. The second stage classified each change as either a reduction, reorganization, or elimination. The final stage of the analysis was to compare the choices made by Linckelmann to those made by Brahms. The results show that Linckelmann's choices for reduction, reorganization, and elimination closely align with those of Brahms. The only differences between the arrangements can be attributed to Linckelmann's focus on retaining the original orchestral timbre and Brahms's focus on providing the original vocal parts.

The Trombone in German and Austrian Concerted Church Music of the Baroque Period: A Lecture Recital, Together with Three Recitals of Selected Works of L. Basset, L. Grondahl, W. Hartley, V. Persichetti, K. Serocki, H. Tomasi, D. White and Others
The dissertation consists of four recitals: three solo recitals and one lecture recital. The repertoire of all the programs was intended to demonstrate a variety of music written originally for trombone. The lecture recital, "The Trombone in German and Austrian Concerted Church Music of the Baroque Period," was presented on July 3, 1974. The lecture was an attempt to illuminate the position of the trombone, both as an ensemble instrument and as a solo obbligato instrument, in church music of the Baroque period. The program included the performance of two works by Heinrich Schutz for bass voice, four trombones, and continuo; one work by Andreas Hammerschmidt for alto, bass, trombone, and continuo; and one work by Johann Joseph Fux for soprano, trombone, two violins, and continuo. A line of influence was traced from the Venetian composers Giovanni Gabrieli and Claudio Monteverdi, through Schiitz, Hammerschmidt, and Fux, to Mozart.

'The Marshall System' in World War II, Myth and Reality: Six American Commanders Who Failed
This is an analysis of the U.S. Army's personnel decisions in the Second World War. Specifically, it considers the U.S. Army Chief of Staff George C. Marshall's appointment of generals to combat command, and his reasons for relieving some generals while leaving others in place after underperformance. Many historians and contemporaries of Marshall, including General Omar N. Bradley, have commented on Marshall's ability to select brilliant, capable general officers for combat command in the war. However, in addition to solid performers like J. Lawton Collins, Lucian Truscott, and George S. Patton, Marshall, together with Dwight D. Eisenhower and Lesley J. McNair, often selected sub-par commanders who significantly underperformed on the battlefield. These generals' tactical and operational decisions frequently led to unnecessary casualties, and ultimately prolonged the war. The work considers six case studies: Lloyd Fredendall at Kasserine Pass, Mark Clark during the Italian campaign, John Lucas at Anzio, Omar Bradley at the Falaise Gap, Courtney Hodges at the Hürtgen Forest, and Simon Bolivar Buckner, Jr. at Okinawa. Personal connections and patronage played strong roles in these generals' command appointments, and often trumped practical considerations like command experience. While their superiors ultimately relieved corps commanders Fredendall and Lucas, field army and …

Authentic Transformational Leadership and Implicit Leadership Theories.
Transformational leadership describes a leader who motivates followers to performance beyond expectations, but it has often been attacked for its potential to be abused. A newer form of leadership has been proposed, that of authentic leadership. Authentic leadership is an over-arching concept that proposes to include transformational leadership and all positive forms of leadership. At the heart of authentic leadership is the concept of ethicality. The concept of authenticity may contribute to the transformational leadership paradigm, producing an ideal form of leadership. Authentic leadership may not be an over-arching form of leadership, but one suited particularly to transformational leadership. I propose that authentic transformational leadership resides in leaders' and followers' implicit leadership theories. This experiment addresses authentic transformational leadership and the role of implicit leadership theories in directing leader behavior. A model is developed that outlines the relationship between authentic transformational leadership and implicit leadership theories, including the separate implicit theories of leader and follower, leader-member exchange (LMX), and leader effectiveness. Hypotheses concerning these relationships are developed. The study is experimental, using WebCT as a delivery tool. Scenario-based surveys were developed to collect data, using both known measures and measures developed specifically for this experiment. Two pilot studies were conducted …

Commonalities Among Women Superintendents in Texas
The major purpose of this descriptive study was to determine common characteristics and influences among women who were serving as public school superintendents of independent districts in Texas during the 1988-89 school year. Commonalities were determined in (1) personal characteristics, (2) personality traits, and (3) perceived barriers to career mobility. A seventy-item survey was developed, validated, and mailed to the thirty-three women superintendents in Texas. Data from the survey were analyzed to determine if commonalities existed among women superintendents. Based on the findings of this study, the following conclusions seem justified: (1) Commonalities in personal characteristics which exist among women superintendents include age, ethnicity, marital status, parenthood, positive attitudes toward being both mothers and superintendents, preference for husbands in the field of education, demonstration of early leadership traits, and self-perceptions of being assertive and risk-taking; (2) Most women superintendents share common views on subjective measures concerning their own personalities, and they rated themselves highest in areas which include self-esteem, general daily activity level, independence, job satisfaction, ability to operate under pressure and practicality; and (3) Most women superintendents perceive similar internal and external barriers to their career mobility; a lack of professional network and employers' negative attitudes toward women are …

Embracing Equality: Texas Baptists, Social Christianity, and Civil Rights in the Twentieth Century
Texas Baptists in the twentieth century struggled to overcome prejudice and embrace racial equality. While historians have generally agreed that Baptist leadership in Texas was more progressive in regard to race relations than that of other southern states, Texas Baptists acquiesced to calls for racial justice with great difficulty. This study seeks to analyze the relationship between Texas Baptists' understanding of social Christianity and their views of racial equality. Furthermore, this study seeks to examine the extent to which white Texas Baptists actually changed their racial views and incorporated African Americans into their church services following the civil rights movement. An analysis of the racial transformation of one of Texas' most famous Baptists, W. A. Criswell, and the history of the Christian Life Commission, which is the ethical arm of the Baptist General Convention of Texas, provides great insight in to the racial progress made by Texas Baptists in the twentieth century. As Texas Baptists enter the twenty-first century and encounter a large and growing Hispanic population, the findings of this study will render aide to those who wish to embark on a new future by learning from the mistakes of their past.

An Examination of Locus of Control, Personality Traits, and Selected Demographic Variables as Factors Relating to the Success of First-Year Students in an Associate Degree Nursing Program
Two major purposes existed for this study. The first purpose was to compare how persisters and nonpersisters in the first year of a two-year nursing program differed in locus of control, selected personality traits, and seven demographic variables. The second major purpose was to develop a predictive model for the persisters and the nonpersisters. The particular personality variables examined were intelligence, superego strength, extraversion, anxiety, tough poise, and independence as measured by the 16PF. The summary findings were that persisters had significantly higher scores on the NDRT and the B and G traits, significantly lower externality, and were generally younger with no previous nursing experience, and more likely not to have prekindergarten age children than the nonpersisters. The major significance of this research comes from its use of data gathered at the beginning of an educational program to make predictions which can be available to teachers, counselors, and administrators who may make use of the information to improve the chance potential nonpersisters have of completing the nursing program, or perhaps to assist students in reexamination of their career choice.

Spectral analysis of the turbulent mixing of two fluids
We describe a spectral approach to the investigation of fluid instability, generalized turbulence, and the interpenetration of fluids across an interface. The Technique also applies to a single fluid with large variations in density. Departures of fluctuating velocity components from the local mean are far subsonic, but the mean Mach number can be large. Validity of the description is demonstrated by comparisons with experiments on turbulent mixing due to the late stages of Rayleigh-Taylor instability, when the dynamics become approximately self-similar in response to a constant body force. Generic forms for anisotropic spectral structure are described and used as a basis for deriving spectrally integrated moment equations that can be incorporated into computer codes for scientific and engineering analyses.

Inertial fusion energy: A clearer view of the environmental and safety perspectives
If fusion energy is to achieve its full potential for safety and environmental (S&E) advantages, the S&E characteristics of fusion power plant designs must be quantified and understood, and the resulting insights must be embodied in the ongoing process of development of fusion energy. As part of this task, the present work compares S&E characteristics of five inertial and two magnetic fusion power plant designs. For each design, a set of radiological hazard indices has been calculated with a system of computer codes and data libraries assembled for this purpose. These indices quantify the radiological hazards associated with the operation of fusion power plants with respect to three classes of hazard: accidents, occupational exposure, and waste disposal. The three classes of hazard have been qualitatively integrated to rank the best and worst fusion power plant designs with respect to S&E characteristics. From these rankings, the specific designs, and other S&E trends, design features that result in S&E advantages have been identified. Additionally, key areas for future fusion research have been identified. Specific experiments needed include the investigation of elemental release rates (expanded to include many more materials) and the verification of sequential charged-particle reactions. Improvements to the calculational methodology are …

Mutual Charge Neutralization of Gaseous Ions
The problem of the bimolecular rate constant, alpha , for the mutual charge neutralization reaction (ion-ion recombination) for ions formed by the vacuum ultraviolet photolysis of nitric oxide is considered. The pressure dependence of alpha over a pressure range of 10 to 600 torr for mixtures of a few hundred microns of NO with He, Ar, Kr, Xe, H/sub 2/, D/sub 2/, and N/sub 2/ was measured. From the low-pressure limit of alpha , the rate constant for charge neutralization in the absence of a third body was found to be k/sub o/ = 2.1 plus or minus 0.4 x 10/sup -7/ cm/sup 3// sec. The high-pressure limit of alpha was estimated to be 2.0 plus or minus 0.5 x 10/sup -6/ cm/sup 3//sec. The third-body efficiencies for promoting the charge-neutralization reaction were measured. The results, relative to He as the third-body gas, are H/sub 2/= 1.4 plus or minus 0.4, D/sub 2/= 1.5 plus or minus 0.4, Ar =3.6 plus or minus 0.8, Kr =4.3 plus or min11.0, N/sub 2/ = 5.2 plus or minus 1.1, and Xe = 6.8 plus or minus 1.5. The average ionic mobility in the gas mixtures is estimated, and the mobilities indicate that …

Differential Distributions of Neutrons in Inelastic π$sup -$P Interactions at 374, 417, and 454 Mev
The inelastic interactions of negative pi mesons with protons at 374, 417, and 454 Mev incident pi kinetic energy are studied by measuring the differential distributions of finalstate neutrons. The pi source is an internal target of the Berkeley 184-inch synchrocyclotron. A magnetic beamtransport system momentum-anaiyzes and focuses the pi beam at a liquid hydrogen target located in an adjacent shielded experimental area. The time-of- flight distribution of neutral particles is measured at various laboratorysystem angles between 10 and 65 deg. Neutral particles are detected by observing the charged products of their interactions in plastic scintillator. The time-of- flight information is determined electronically by time-to-height conversion and pulse-height analysis. The time resolution of the total system is 1.0 nsec. Detected neutral particles accompanied by charged particles are separated by the electronic system from those not accompanied by charged particles. Analysis presuming the principal inelastic reactions to be pi /sup -/p yields pi /sup +/ pi /sup -/n and pi /sup -/p yields pi /sup 0/ pi /sup 0/n separates the time-of-flight spectra into gamma rays, neutrons from the reaction pi /sup -/p yields pi /sup 0/n, and inelastic neutrons. Calculated values of the neutron- detection efficiency are used in the …

Scaling supernova hydrodynamics to the laboratory
Supernova (SN) 1987A focused attention on the critical role of hydrodynamic instabilities in the evolution of supernovae. To test the modeling of these instabilities, we are developing laboratory experiments of hydrodynamic mixing under conditions relevant to supernovae. Initial results were reported in J. Kane et al., Astrophys. J.478, L75 (1997) The Nova laser is used to shock two-layer targets, producing Richtmyer-Meshkov (RM) and Rayleigh-Taylor (RT) instabilities at the interfaces between the layers, analogous to instabilities seen at the interfaces of SN 1987A. Because the hydrodynamics in the laser experiments at intermediate times (3-40 ns) and in SN 1987A at intermediate times (5 s-10{sup 4} s) are well described by the Euler equations, the hydrodynamics scale between the two regimes. The experiments are modeled using the hydrodynamics codes HYADES and CALE, and the supernova code PROMETHEUS, thus serving as a benchmark for PROMETHEUS. Results of the experiments and simulations are presented. Analysis of the spike and bubble velocities in the experiment using potential flow theory and a modified Ott thin shell theory is presented. A numerical study of 2D vs. 3D differences in instability growth at the O-He and He-H interface of SN 1987A, and the design for analogous laser experiments …

A Comparison of Middle Aged and College Aged Adults' Perceptions of Elder Abuse
The purpose of this study was to examine the impact of (a) respondent age, (b) age and gender of perpetrator and victim, and (c) history of experienced violence on perceptions of elder abuse. Two-hundred and one (N = 201) middle-aged adults and 422 college students were assessed. Measures included adaptations of the Severity of Violence Against Women Scale and Elder Abuse Attitudes and Behavioral Intentions Scale-Revised. Middle-aged respondents viewed psychological behaviors more harshly than young. Middle-aged females and young males were less tolerant of middle-aged perpetrators. While past performance of elder abuse was predictive of future elder abuse, history of childhood abuse was not. Exploratory analyses examined middle-aged respondents' judgments of abusive behaviors and perceptions based on age of perpetrator. Middle-aged and young adults' willingness to respond to dimensions of quality, severity, and reportability were also examined.

Mother-Infant Interaction with Facially Deformed Infants
This study investigated the interactions of facially deformed infants (FD) with their mothers compared to a facially nondeformed control group (FND). All mother-infant dyads were videotaped for 10 minutes during a free play period. Mothers were instructed to spend time with their baby as they normally would. The videotaped interactions of 14 FD dyads and 14 FND dyads were rated by five raters for quality of interactions, amount of vocalization, touch, and face-to-face gaze. The infants were rated on their level of attractiveness from polaroid pictures and videotapes. Mothers also completed a questionnaire which assessed their infants' temperament. Three of the studies' four hypotheses were confirmed. First, the more attractive an infant was, the better his/her interactions with the mother were judged to be. Second, FD infant dyads were rated as significantly poorer in quality of interaction than FND dyads, although FD* dyads did not spend significantly less time vocalizing, touching, or in face-to-face gaze as predicted. A significantly higher percentage of FD infants were judged as having difficult temperament relative to FND infants. Finally, as predicted it was found that infants with difficult temperaments were more likely to exhibit poorer quality interactions than infants with less difficult temperaments. These …

Mechanics of Metals with Phase Changes
New experimental data is presented on some exotic metals that exhibit phase changes at cryogenic temperatures. The types of phase changes that were detected in the specific heat data range from martensitic (diffusion less) transitions to superconducting transitions. In addition, the charge density wave (CDW) state in uranium metal was detected in the specific heat. Specific-heat measurements were made in zero-magnetic field using an apparatus capable of obtaining temperatures as low as 0.4 K. Calibration performed on this apparatus, using a single-crystal copper sample, show its accuracy to be 0.50%, while the resolution was better than 0.1%. Our measurements demonstrate that similar high precision and accurate specific-heat measurements can be obtained on milligram-scale samples. In Chapters 2 and 3, specific-heat measurements are presented for the B2 (CsCl structure) alloy AuZn and for {alpha}-uranium (orthorhombic symmetry). The AuZn alloy exhibits a continuous transition at 64.75 K and an entropy of transition of ({Delta}S{sub tr}) 2.02 J K{sup {minus}1} mol{sup {minus}1}. Calculation of the Debye temperature, by extrapolating of the high temperature phase elastic constants to T = 0 K yields a value of 207 K ({+-}2 K), in favorable agreement with the calorimetric value of 219 K ({+-}0.50 K), despite the …

An Evaluation of Unsaturated Flow Models in an Arid Climate
The objective of this study was to evaluate the effectiveness of two unsaturated flow models in arid regions. The area selected for the study was the Area 5 Radioactive Waste Management Site (RWMS) at the Nevada Test Site in Nye County, Nevada. The two models selected for this evaluation were HYDRUS-1D [Simunek et al., 1998] and the SHAW model [Flerchinger and Saxton, 1989]. Approximately 5 years of soil-water and atmospheric data collected from an instrumented weighing lysimeter site near the RWMS were used for building the models with actual initial and boundary conditions representative of the site. Physical processes affecting the site and model performance were explored. Model performance was based on a detailed sensitivity analysis and ultimately on storage comparisons. During the process of developing descriptive model input, procedures for converting hydraulic parameters for each model were explored. In addition, the compilation of atmospheric data collected at the site became a useful tool for developing predictive functions for future studies. The final model results were used to evaluate the capacities of the HYDRUS and SHAW models for predicting soil-moisture movement and variable surface phenomena for bare soil conditions in the arid vadose zone. The development of calibrated models along …
