An Analytical Study of Robert Muczynski's Second Piano Trio
The purpose of this study is to provide scholastic research on Robert Muczynski's Second Piano Trio (1975) by presenting his biographical background, discussing influences and his musical style, and analyzing the work. Robert Muczynski (b.1929), a composer-pianist of Polish descent, studied with Alexander Tcherepnin (1899-1977). From traditional forms and techniques, he fashioned his own unique and innovative compositional style. The second piano trio, in particular, was deeper and more complex in its conception and affect than previous compositions. The first movement Andante molto opening leads to an allegro section, and the somber second movement builds to a heavy climax. The third movement is highly rhythmic and dramatically driven. Chapter I outlines the purpose of the study and the composer's biography. Chapter II describes Muczynski's compositional influences and the evolution of his musical language. Emphasis in this respect will be placed on the pedagogical role of Alexander Therepnin, as well as the important connections between Prokofiev, Tcherepnin and Muczynski. An exploration of other elements that have informed Muczynski's style is offered. Chapter III details the circumstances, general characteristics, and compositional technique of the Second Piano Trio. Detailed analysis of all three movements will be provided, with particular attention paid to aspects …

The Effects of an Inquiry-based American History Program on the Achievement of Middle School and High School Students.
Implicit in the call for educational reform in the teaching of social studies has been the suggestion that pursuing inquiry-based principles will lead to improvement in student achievement. The purpose of this study was to compare the effectiveness of two types of pedagogy: traditional and inquiry-based upon student achievement as measured by a standards-based, state administered examination. Second, this study examined the relationship between the treatment teachers' level of implementation and student achievement. A nonequivalent control group posttest and experimental design was used in this study. Subjects involved in this study include 84 secondary American history teachers and their respective students from a large urban public school district in Texas. The sample consisted of two groups, one taught by traditional/didactic instruction (n=48) and the other taught by inquiry-based pedagogy (n=36). Data for this study were collected using a classroom observation protocol based upon the level of use rubric developed by the concerns-based adoption model. An analysis of variance (ANOVA) (p<.05) was used to measure the effects of inquiry-based instruction and traditional pedagogy on student achievement. Student achievement results were measured by the Texas Assessment of Knowledge and Skills (TAKS) for American history, grades 8 and 11. The study found that …

Faith and politics: The socio-political discourses engaged by Mexican ex-voto paintings from the nineteenth-century and beyond.
The Universalis Ecclesiae of 1508 authorized Spanish colonization of the Americas in return for the conversion of native populations to Christianity. From its inception therefore, the Mexican nation lived an alliance between Church and State. This alliance promoted the transfer of Castilian Catholicism to American shores. Catholic practices, specifically the ex-voto tradition, visualize this intermingling of religion and politics. The ex-voto is a devotional painting that expresses gratitude to a religious figure for his/her intervention in a moment of peril. It is commissioned by the devotee as a means of direct communication to the divine. This project analyzes 40 Mexican ex-votos for their reflection of political issues in Mexico. I assert that the Mexican ex-votos engage discussions of social politics. To support this argument, visualizations of socio-political discourses such as the Virgin of Guadalupe as a national religious symbol, police action and economic disparity were examined.

The Stabat Mater of Herbert Howells: The Agony and the Ecstasy
Access:
Use of this item is restricted to the UNT Community
Herbert Howells composed three large works for chorus and orchestra: a requiem (Hymnus Paradisi), Latin mass (Missa Sabrinensis) and finally a Stabat Mater. Writings, performances and recordings of the Stabat Mater, however, have been few. As the Stabat Mater is believed to be the culmination of his musical prowess, it is important to bring this major work to light. Chapter 1 begins with a brief introduction to Herbert Howells, then continues as a brief biographical sketch. Howells's life is discussed from birth, as organ scholar, student at the Royal College of Music, his teaching professorship at the same institution, and important compositions by decade until his death. Chapter 2 is an overview of the Hymnus Paradisi and Missa Sabrinensis. The chapter gives historical information on each work, including reasons for commission, dates of composition and performance, orchestration and choral composition, type of soloists, conductor and recordings. Chapter 3 is an in depth study of the Stabat Mater. The chapter includes reasons for the genesis of the work, current and past events that affected the composition, musical influences, and the death of his son Michael Kendrick Howells. A second section to this chapter addresses the text of the Stabat Mater, including …

Automated Low-cost Instrument for Measuring Total Column Ozone
Access:
Use of this item is restricted to the UNT Community
Networks of ground-based and satellite borne instruments to measure ultraviolet (UV) sunlight and total column ozone have greatly contributed to an understanding of increased amounts of UV reaching the surface of the Earth caused by stratospheric ozone depletion. Increased UV radiation has important potential effects on human health, and agricultural and ecological systems. Observations from these networks make it possible to monitor total ozone decreases and to predict ozone recovery trends due to global efforts to curb the use of products releasing chemicals harmful to the ozone layer. Thus, continued and expanded global monitoring of ozone and UV is needed. However, existing automatic stratospheric ozone monitors are complex and expensive instruments. The main objective of this research was the development of a low-cost fully automated total column ozone monitoring instrument which, because of its affordability, will increase the number of instruments available for ground-based observations. The new instrument is based on a high-resolution fiber optic spectrometer, coupled with fiber optics that are precisely aimed by a pan and tilt positioning mechanism and with controlling programs written in commonly available software platforms which run on a personal computer. This project makes use of novel low-cost fiber optic spectrometer technology. A cost …

A Study of Franz Liszt's Totentanz: Piano and Orchestra Version, and Piano Solo Version
Access:
Use of this item is restricted to the UNT Community
Undoubtedly, Totentanz has been one of the most famous works by Franz Liszt. Totentanz has been recorded by many pianists and addressed in much of the vast literature about Liszt and his works; however, little research has been focused on this work. Most studies of Totentanz address only the historical background of the piece in relation to the theme based on Dies irae. Currently, there are no specific studies about the solo piano or two piano versions and only one recording was located. Liszt's own piano solo transcription of this famous work is an excellent addition to the concert repertoire. Totentanz consists of six variations that include canonic and fugato sections. The main theme is based on the Gregorian chant Dies irae, a melody that has been used by many other composers, most notably Berlioz in Witches Sabbath of Symphonie fantastique, op. 14 and Rachmaninoff in Rhapsody on a Theme of Paganini. This study contains five chapters. Chapters I and II provide background information, historical background and influences of Totentanz. Chapter III presents an outline of Liszt's achievement as a transcriber. Liszt revised his own works numerous times from the 1840s and 1850s, including Transcendental Etudes, Paganini Etudes, and piano …

Regulation of pyrimidine biosynthesis and virulence factor production in wild type, Pyr- and Crc- mutants in Pseudomonas aeruginosa.
Previous research in our laboratory established that pyrB, pyrC or pyrD knock-out mutants in Pseudomonas aeruginosa required pyrimidines for growth. Each mutant was also discovered to be defective in the production of virulence factors. Moreover, the addition of exogenous uracil did not restore the mutant to wild type virulence levels. In an earlier study using non-pathogenic P. putida, mutants blocked in one of the first three enzymes of the pyrimidine pathway produced no pyoverdine pigment while mutants blocked in the fourth, fifth or sixth steps produced copious quantities of pigment, just like wild type P. putida. The present study explored the correlation between pyrimidine auxotrophy and pigment production in P. aeruginosa. Since the pigment pyoverdine is a siderophore it may also be considered a virulence factor. Other virulence factors tested included casein protease, elastase, hemolysin, swimming, swarming and twitching motilities, and iron binding capacity. In all cases, these virulence factors were significantly decreased in the pyrB, pyrC or pyrD mutants and even in the presence of uracil did not attain wild type levels. In order to complete this comprehensive study, pyrimidine mutants blocked in the fifth (pyrE) and sixth (pyrF) steps of the biosynthetic pathway were examined in P. aeruginosa. …

NEPSY profiles in children diagnosed with different ADHD subtypes.
The purpose of this study was to determine if attention-deficit/hyperactivity disorder (ADHD) subtypes (predominantly hyperactive/impulsive, ADHD-HI; predominantly inattentive, ADHD-IA; combined, ADHD-C) exhibit distinct neuropsychological profiles, using the Attention and Executive Function subtests of the Developmental Neuropsychological Assessment, (NEPSY) and the omission and commission scores obtained on the Conners' Continuous Performance Test-II (CPT-II), a test that assesses attention processes. The sample was selected using archival data collected in a neurodevelopmental clinic over the past decade and consisted of 138 children between the ages of 6 and 12 years old. Using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) criteria, the children were placed in either the ADHD-HI (n = 40), ADHD-IA (n = 35), or ADHD-C (n = 36) group, or a symptom free comparison group (n = 27). It was hypothesized that children with elevations on the impulsivity/ hyperactivity (ADHD-HI and ADHD-C) scale would be impaired on measures of inhibition and those with elevations on the inattention scale (ADHD-IA and ADHD-C) would be impaired on tests of attention, vigilance, and other executive functions. A one-way multivariate analyses of variance (MANOVA) was conducted (Group X Task), with significant results for overall main effect for group on the 7 …

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization
Access:
Use of this item is restricted to the UNT Community
In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.

Access:
Use of this item is restricted to the UNT Community
The propose of this study was to determine the effectiveness and appropriateness of the integrated holistic method for teaching grammatical structure, cultural norms and behavior, writing and listening skills to beginning German language students. The study examined a sample of undergraduate students who were enrolled in the introductory college level German offered at the Collin County Community College, Spring Creek Campus in Plano, Texas. A total of 24 students participated in this study. This study utilized a pre- and posttest group to measure the instructional effectiveness of the integrated holistic teaching method. Structural grammar, cultural norms and behavior, writing, and listening skills were used as dependent variables. The holistic integrated teaching method were measured at the end of the course as independent variables. Individual pre- and posttests were used for each of the dependent variables. The higher posttest mean scores indicated significant improvement in student learning level in four major language skills such as structural grammar, cultural norms and behavior, writing, and listening through the holistic integrated teaching method.

Germanic Women: Mundium and Property, 400-1000
Abstract Many historians would like to discover a time of relative freedom, security and independence for women of the past. The Germanic era, from 400-1000 AD, was a time of stability, and security due to limitations the law placed upon the mundwald and the legal ability of women to possess property. The system of compensations that the Germans initiated in an effort to stop the blood feuds between Germanic families, served as a deterrent to men that might physically or sexually abuse women. The majority of the sources used in this work were the Germanic Codes generally dated from 498-1024 AD. Ancient Roman and Germanic sources provide background information about the individual tribes. Secondary sources provide a contrast to the ideas of this thesis, and information.
