Analysis of harp performance issues in Federico's Little Songs for Children by George Crumb.

Analysis of harp performance issues in Federico's Little Songs for Children by George Crumb.

Date: May 2009
Creator: Hembreiker, Linda-Rose
Description: During the 20th century, chamber works for harp expanded to include significantly different instrumentations, like flute, voice and harp. Indeed, a body of works for flute, voice, and harp began to develop mainly through the commissioning efforts of ensembles comprised of these instruments. This study of George Crumb's Federico's Little Songs for Children for flutes, soprano, and harp considers the unique advantages and challenges of this instrumentation and offers specific suggestions for performance. Attention to various compositional elements of Federico's Little Songs for Children, especially as they relate to the text, is also helpful in preparing to perform this work. The form, pitch material, and text-painting in the work allow for special opportunities to convey meaning to audiences in ways that do not rely on traditional tonal relationships. Accompanying the shift away from traditional tonal relationships, the development of the harp repertoire in chamber and solo settings during the 20th century also led to the development of many extended- techniques for this instrument. For the most part, these techniques have been described and given various notational symbols but not discussed in detail with regard to execution. Federico's Little Songs for Children itself requires several unique extended-techniques. Recommendations are given in ...

Variability-aware low-power techniques for nanoscale mixed-signal circuits.

Variability-aware low-power techniques for nanoscale mixed-signal circuits.

Date: May 2009
Creator: Ghai, Dhruva V.
Description: New circuit design techniques that accommodate lower supply voltages necessary for portable systems need to be integrated into the semiconductor intellectual property (IP) core. Systems that once worked at 3.3 V or 2.5 V now need to work at 1.8 V or lower, without causing any performance degradation. Also, the fluctuation of device characteristics caused by process variation in nanometer technologies is seen as design yield loss. The numerous parasitic effects induced by layouts, especially for high-performance and high-speed circuits, pose a problem for IC design. Lack of exact layout information during circuit sizing leads to long design iterations involving time-consuming runs of complex tools. There is a strong need for low-power, high-performance, parasitic-aware and process-variation-tolerant circuit design. This dissertation proposes methodologies and techniques to achieve variability, power, performance, and parasitic-aware circuit designs. Three approaches are proposed: the single iteration automatic approach, the hybrid Monte Carlo and design of experiments (DOE) approach, and the corner-based approach. Widely used mixed-signal circuits such as analog-to-digital converter (ADC), voltage controlled oscillator (VCO), voltage level converter and active pixel sensor (APS) have been designed at nanoscale complementary metal oxide semiconductor (CMOS) and subjected to the proposed methodologies. The effectiveness of the proposed methodologies has ...

From reactionary to responsive: Applying the internal environmental scan protocol to lifelong learning strategic planning and operational model selection.

From reactionary to responsive: Applying the internal environmental scan protocol to lifelong learning strategic planning and operational model selection.

Date: May 2009
Creator: Downing, David, L.
Description: This study describes and implements a necessary preliminary strategic planning procedure, the Internal Environmental Scanning (IES), and discusses its relevance to strategic planning and university-sponsored lifelong learning program model selection. Employing a qualitative research methodology, a proposed lifelong learning-centric IES process based on Bryson's (2004) strategic planning model was tested at a large public university in the American Southwest with the intention of both refining the IES process for general use in the field as well as providing a set of useable reference documents for strategic planners at that university. The prototype lifelong learning IES process as tested proved to be highly effective in identifying and categorizing previously unrecognized lifelong learning programming and organizational structures and, was reasonably efficient in process execution. Lessons learned from the application of the prototype lifelong learning IES procedure led to the development of a revised scanning procedure. This revised procedure is considered more reliable and can be accomplished by a single investigator in as little as 35 production hours, providing a detailed snapshot of the total university lifelong learning system and a point of departure for the larger strategic planning effort.

Effects of Picture Exchange Training on Communication Topographies

Effects of Picture Exchange Training on Communication Topographies

Date: May 2009
Creator: Haray, Aimee H.
Description: The Picture Exchange Communication System (PECS) has been used with children with autism and other developmental disabilities as an alternative to vocal communication. Some researchers have reported rapid acquisition of picture-exchange requesting as well as increased vocal speech and increased spontaneous social interactions following PECS training. Earlier research has found that although 3 children with autism learned to exchange pictures for preferred items during PECS training, requesting topographies did not change and vocal speech did not increase after PECS training. The present study evaluated the effects of PECS training on requesting topographies, especially vocal speech, with 3 participants with autism and mental retardation. Only one participant maintained picture-exchange requesting, and none of the participants showed an increase in vocal speech during probe sessions conducted after each PECS training phase.

Augeries, for Flute, Clarinet, Percussion and Tape: Aesthetic Discussion and Theoretical Analysis

Augeries, for Flute, Clarinet, Percussion and Tape: Aesthetic Discussion and Theoretical Analysis

Date: May 2009
Creator: Gedosh, David
Description: Augeries is a multi-channel electro-acoustic composition for flute, clarinet, percussion, and tape. It is intended to be diffused through an 8-channnel playback system. Inspired by the first four lines of William Blake's Augeries of Innocence, Augeries captures the qualitative aspects of Blake's poetry by presenting the listener with an equally aperspectival aesthetic experience. The small-scale structure reflected on the large-scale form - the infusion of vastness and expansiveness into the fragile and minute. Augeries incorporates techniques of expansion and contraction, metonymic relationships, dilation and infolding of time, and structured improvisation to create an experience that is designed to explore the notion of musical time, and to bring to the listener the sense of time freedom. The critical analysis suggests that the increase in the notions of musical time, the aesthetics with which they conform, and the new time forms created, encapsulate communicative significance. This significance exists within a horizon of meaning. Semiotics illuminates an understanding of the structuring techniques used to render time as an area of artistic play. Understanding the aesthetics and mechanisms through which these techniques can be used constitutes a shared horizon of meaning. The concepts of cultural phenomenologist Jean Gebser, as explicated in The Ever-Present Origin, ...

The Lessons of Arnold Schoenberg in Teaching the Musikalische Gedanke

The Lessons of Arnold Schoenberg in Teaching the Musikalische Gedanke

Date: May 2009
Creator: Conlon, Colleen Marie
Description: Arnold Schoenberg's teaching career spanned over fifty years and included experiences in Austria, Germany, and the United States. Schoenberg's teaching assistant, Leonard Stein, transcribed Schoenberg's class lectures at UCLA from 1936 to 1944. Most of these notes resulted in publications that provide pedagogical examples of combined elements from Schoenberg's European years of teaching with his years of teaching in America. There are also class notes from Schoenberg's later lectures that have gone unexamined. These notes contain substantial examples of Schoenberg's later theories with analyses of masterworks that have never been published. Both the class notes and the subsequent publications reveal Schoenberg's comprehensive approach to understanding the presentation of the Gedanke or musical idea. In his later classes especially, Schoenberg demonstrated a method of analyzing musical compositions using illustrations of elements of the Grundgestalt or "basic shape," which contains the technical aspects of the musical parts. Through an examination of his published and unpublished manuscripts, this study will demonstrate Schoenberg's commitment to a comprehensive approach to teaching. Schoenberg's heritage of eighteenth- and nineteenth-century music theory is evident in his Harmonielehre and in his other European writings. The latter include Zusammenhang, Kontrapunkt, Instrumentation, Formenlehre (ZKIF), and Der musikalische Gedanke und die Logik, ...

Role of Parental Anxiety on Pediatric Feeding Disorders

Role of Parental Anxiety on Pediatric Feeding Disorders

Date: May 2009
Creator: Didehbani, Nyaz
Description: The proposed study examined the relationship between parental anxiety, measured both subjectively (via self-report questionnaires) and objectively (via salivary cortisol) and the child's feeding progress. Children diagnosed with a feeding disorder were recruited with their parents at Our Children's House at Baylor (n=19; 11 females, 8 males). The patients and their parents were housed in the clinic for an eight-week intensive multidisciplinary pediatric feeding disorder treatment program. Calorie intake was recorded daily as outcome measures of treatment progression. Parental anxiety was measured by the Pediatric Inventory for Parents (PIP), state anxiety on the State Trait Anxiety Inventory (STAI), and by salivary cortisol at three different time points. The present study attempted to examine whether parental feeding (phase three of treatment program) would continue to cause a decrease in the child's caloric intake. In averaging ten meals prior to parental feeding in comparison to the average of ten meals following parental feeding, there was no significant difference as measured by a t-test. Paired t-tests examined parental anxiety from time one to time two and found that salivary cortisol increased significantly t(15) = -6.07, p = .000 from Time 1 (M = 2.30, SD = 1.64) to Time 2 (M = 5.24, ...

Attitudes of International Music Students from East Asia toward U.S. Higher Education Institutions

Attitudes of International Music Students from East Asia toward U.S. Higher Education Institutions

Date: May 2009
Creator: Choi, Jin Ho
Description: Nine universities in the United States with the greatest number of international students and having an accredited music program through the National Association of Schools of Music (NASM) were selected. Survey research methodologies were used to identify the status of the international music students from East Asia in U.S. higher education institutions and to determine their attitudes toward their schools. Among East Asian international music students at US higher education institutions, the results indicated that the professor's reputation, scholarships, and the program's reputation were perceived as the most influential factors impacting the program choice; a good relationship with professors, good feedback from professors, and emotional stability were perceived as the most influential factors impacting academic success; and the professor's teaching, the professor's expertise, and the improvement of musical skills were perceived as the most influential factors impacting students' satisfaction level. The most problematic issues reported were the language barrier and the cultural differences between their host and own countries. In addition, many of the East international music students in this study noted financial difficulties.
