Recital presented at the UNT College of Music Recital Hall in partial fulfillment of the Doctor of Musical Arts (DMA) degree.

Since Jasmine's Secret contains elements of cantata and follows a dramatic story or program, the work may be classified as a narrative or dramatic story or program, the work may be classified as a narrative or dramatic cantata employing five solo voices, narrator and orchestra. This work attempts a revival of these two genres as a combined entity due to the decreased popularity of both cantata and programmatic music in the 20th century.

The purpose of this study was to investigate the ability of trained musicians and musically untrained college students to discriminate music instrument timbre as a function of duration. Specific factors investigated were the thresholds for timbre discrimination as a function of duration, musical ensemble participation as training, and the relative discrimination abilities of vocalists and instrumentalists. Under the conditions of this study, it can be concluded that the threshold for timbre discrimination as a function of duration is at or below 20 ms. Even though trained musicians tended to discriminate timbre better than musically untrained college students, musicians cannot discriminate timbre significantly better then those subjects who have not participated in musical ensembles. Additionally, instrumentalists tended to discriminate timbre better than vocalists, but the discrimination is not significantly different. Recommendations for further research include suggestions for a timbre discrimination measurement tool that takes into consideration the multidimensionality of timbre and the relationship of timbre discrimination to timbre source, duration, pitch, and loudness.

Breakdown is a 17 minute, single movement work for orchestra in five sections. It is scored for 2 flutes, 2 oboes, 2 Bb clarinets, 2 bassoons, 3 Bb trumpets, 4 horns in F, 3 trombones, tuba, percussion, piano, and strings. The percussion consists of a tam-tam, 5 break drums, 4 timbales, 2 gourds, chimes, marimba, vibraphone, snare drum, 2 field drums, bass drum and tympani. The inspiration for this work is the poetry of Bruce Weigl which deals with many facets of the Vietnam experience. One particular work from his collection Song of Napalm, the poem "Breakdown", provided the basis for the emotional and structural content of the music. There are two primary sources of pitch material in the music of Breakdown, both of which have links to the Vietnam War. The name of a soldier who was killed in Vietnam, Miles Cooper, was used to generate a basic pitch set and a series of variation sets that provide much of the harmonic and melodic material in Breakdown. There derived sets are supported by the use of phrases and motives from the hymn Jewels, which celebrates the love of God for his children, and providesan indirect link to the subject …

This study examines the relationship between sonnet form and musical form in Benjamin Britten's sonnet cycles with a view toward identifying the musico-poetic form how the musical form interprets the poetry. Several issues come to the fore: 1) articulation of the large-scale divisions of the poetic form in the music; 2) potential of the musical setting to make connections between lines of the text ; 3) potential of the musical setting to follow or imitate the thought processes of the poem; and 4) placement of the departure and return.

A body of works titled 'capriccio' have existed for over four hundred years. Most of these works are characterized by a composers abandonment of expected stylistic norms. Guided only by the fanciful whim of the composer, a capriccio exhibits extreme contrasts in the various parameters of a musical composition including melody, harmony, counterpoint, mood and texture. The composition embedded in these compositional parameters as its point of departure and development.

A limited amount of research exists that addresses low self-esteem, poor self-concept, and distorted self-image in children with Attention-deficit Hyperactivity Disorder (ADHD). The most urgent task is to test assumptions regarding self-perception and to assess the dimensions of self-concept influenced by this disorder. The Self-Perception Profile for Children (Harter, 1985) was used in the present study to assess those dimensions. Participants included 34 boys with ADHD, 27 boys with LD, and 33 boys without any diagnosed psychological or learning problems. Results were analyzed using Pearson's product-moment correlation, analyses of variance (ANOVA), and analyses of covariance (ANCOVA) and did not support the hypotheses.

Te Deum is a single movement work for chorus and orchestra. It employs an ensemble comprising the complement of string, woodwind, and brass instruments typically available in a small symphony orchestra with an expanded percussion section. The choral forces are in proportional relation to the instrumental forces are in proportional relation to the instrumental forces and it is sung in the original Latin. The intended performance time is approximately 18 minutes. Temporal aspects of the work are characterized by three contrasting sections. The slow and solemn opening section is given to long stretches of silence sparsely punctuated by low drums. The remainder of the work is texturally more dense and employs a much quicker tempo. A steady core pulse is also a key feature, with attention given to avoiding any regular metrical implications by use offset accents, non-consecutive identical phrase lengths, and a slow harmonic rhythm.

A prototype Compton scatter camera for imaging gamma rays has been built and tested. This camera addresses unique aspects of gamma-ray imaging at nuclear industrial sites, including gamma-ray energies in the 0.5 to 3.0 MeV range and polychromatic fields. Analytic models of camera efficiency, resolution and contaminating events are developed. The response of the camera bears strong similarity to emission computed tomography devices used in nuclear medicine. A direct Fourier based algorithm is developed to reconstruct two-dimensional images of measured gamma-ray fields. Iterative ART and MLE algorithms are also investigated. The point response of the camera to gamma rays of energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms are also investigated. The point response of the camera to gamma rays energies from 0.5 to 2.8 MeV is measured and compared to the analytic models. The direct reconstruction algorithm is at least ten times more efficient than the iterative algorithms and produces images that are, in general, of the same quality. Measured images of several phantoms are shown. Important results include angular resolutions as low as 4.4{degrees}, reproduction of phantom …

Maturation of spinal motoneurons in rodents is characterized by a period of cell loss in the embryo, but researchers have claimed that some cell death occurs postnatally. This form of cell death is called apoptosis and involves active participation of the cell. Apoptotic cells have certain recognizable morphological and molecular features. I have used a monoclonal antibody against ubiquitin, (a putative marker of apoptotic cells), to do immunochemistry on mouse spinal cords at various postnatal ages till early adulthood. Staining is seen in large amotoneurons in the ventral horn. Staining is intense till P28, and faint thereafter. Substantial proportions of motoneurons stain till P21, followed by a sharp decline in the number of immunopositive cells. None of the cells exhibit signs of apoptosis.

In this study, nineteen cases of suspected or clinically diagnosed Prader-Willi Syndrome (PWS) were tested for molecular deletions by in situ hybridization with two DNA probes, IR4-3R and GABRB3. Both probes are specific for sequences within the chromosome region 15q11-13, with IR4-3R located within the putative PWS region and GABRB3 in the distal area associated with Angelman Syndrome.

This study examined the influences of a variety of verbal and non-verbal strategies on the language acquisition of six fourth grade ESL students in a discipline-based art education classroom. The art teacher/researcher spoke only English, and the students spoke Spanish almost exclusively. The art instruction occurred during eighteen 30 minute sessions, over a period of five months. The program involved the whole language approach, collaborative/cooperative learning, and the study of art concepts through verbal and graphic symbol cue cards and images of art works. Data were amassed from transcripts of video recordings, student and teacher interviews, and reflective notes. This study showed highly successful results with student growth in language acquisition and comprehension of art concepts.

This investigation sought to determine how seventh-grade social studies teachers perceive TAAS objectives for social studies, language arts, and mathematics and how they apply them in the classroom. A detailed questionnaire was submitted to fifty teachers in the Dallas metropolitan area; a 72 percent. return was received. Though teachers expressed a favorable attitude toward emphasizing the higher-level thinking objectives, many indicated that their lesson plans and teaching methods have remained unchanged in the past year. The data suggests that teachers want and need additional training and teaching resources to satisfy the call for incorporating performance-based assessment into the classroom curriculum. TAAS standards cannot drive the intended curriculum improvements without a model for reorienting instructional practices.

In the last several years, there has been an interest in graphical user interfaces as compared with character user interfaces. The "mouse" is the device most closely associated with graphical user interfaces. Key strokes are more closely associated with character user interfaces. Given these associations, is there a preference for the keyboard or for the mouse as an input device? The determination of user preference was reduced to the determination of preference of key strokes or mouse clicks for selection of main menu items. The subjects, university students working with Microsoft Works by Microsoft Corporation, copyright 1987-1989, were learning how to use application software. While Microsoft Works was running, tracking software recorded every user key stroke and mouse click, together with data about these key strokes and mouse clicks. From the analysis of these data, common preference for the means of menu item selection was determined.

This paper investigates Ronald Stevenson's unique treatment of large-scaled structure in his Passacaglia on D S C H. This piece's unusual eighty-minute length, use of traditional forms and unusual piano techniques, musical references to other cultures and a massive triple-fugue over a ground bass will be examined as they relate to its overall form. The elements of rhythm, melody/mode, harmony, counterpoint, piano techniques, and tonality are also used as means of highlighting many unifying elements of the piece which contribute to its overall cohesiveness. Tributes to other composers, among them Dimitry Shostakovich to whom the piece is dedicated, are discussed in addition to many references to world cultures and events which support Stevenson's views on what he terms world music. Rarely is a piece written that encompasses such a wide range of musical elements that possess the ability to engage an audience for an uninterrupted length of eighty-minutes. As of yet, an in-depth scholarly investigation of Stevenson's treatment of formal unity in this landmark piano work has not been done. This analysis reveals Stevenson's approach to composing in such a large form, as well as illustrating his mastery of variation, counterpoint and unending ingenuity for innovative piano techniques. The composer's …

Southern Baptist-Related college faculty attitudes and opinions on areas of higher education most important to the professoriate as identified by the Carnegie Foundation in its 1989 National Survey of Faculty are described in this study and compared with the data from the survey reported by the Carnegie Foundation in The Condition of the Professoriate: Attitudes and Trends, 1989 and Scholarship Reconsidered: Priorities of the Professoriate. The data were compared in the eight areas: goals of collegiate education, academic standards, attitudes about student life, teaching, research, and service, status of the profession, views of the institution, participation in decision-making, and general observations of higher education.

The purpose of this study was to describe and analyze how Homecourt, a nondirective support group at a public high school in the Dallas/Fort Worth area, operates and how it affects students.

This purpose of this research study was to identify key differences that distinguish stepfamilies from intact families with regard to individual members' perceptions of family environment and family functioning. Additionally, an initial look at how membership in a stepfamily impacts the young children's perceptions of interpersonal family functioning is offered.

Various constructs are related to predicting consumers' perceptions of brand extensions. Among these, three constructs, perceptions of perceived quality (PQ) associated with the parent brand, product category similarity (PCS) of an extension to its parent brand, and brand breadth (BB) of the parent, are central to many brand extension studies. The purpose of this study is to clarify the roles of these three constructs and to pit predictions from an alternative theoretical perspective — cognitive response theory — against predictions based on categorization theory.

The purpose of this study was to investigate the kinetic structures or reinforcement schedules of metric temporal patterns (metric combination of note values within a measure) in five best-selling beginning piano method series. Based upon a survey mailed to 98 music dealers, the five best-selling beginning piano method series in 1992 and 1993 were identified as: the Alfred Basic Piano Library, Bastien Piano Basics, David Carr Glover Piano Library, John. W. Schaum Piano Course, and John Thompson Modern Course for Piano. A coding system was developed for identifying the numerical appearances and occurrences of various metric temporal patterns per learning piece within each method series. Several computer programs were written to compute the kinetic structures, scope, and pacing of metric temporal patterns for each method series. The derived data were then compared to delineate relationships between the three analytical variables.

The relationship between adult attachment style and romantic relationship quality in marriage relationships was explored. Romantic relationship quality was measured at the working model (or perceptual) and the behavioral levels. No previous research had investigated romantic relationship quality as reflecting specific attachment related perceptions of self and spouse or as attachment related behaviors. Two hundred and six married subjects were recruited from university campuses, churches, and on an individual basis. Most of the subjects were white, middle class, and had children. Subjects completed self-report questionnaires measuring adult attachment style, working model of self and romantic partner, and reports of relationship behaviors of self and romantic partner. The first hypothesis proposed that attachment style differences would be seen in specific attachment related working models of self and romantic partner. The second hypothesis proposed that attachment style differences would be seen in reports of attachment related behaviors for self and romantic partner. Hypotheses were tested using multivariate analysis of variance.

It has been hypothesized that a disproportionate percentage of the blind population are learning disabled. In the past, norms and technology were not available to assess in a cost effective manner the blind client's neuropsychological functioning. Norms for the Wide Range Achievement Test - Revised (WRAT-R2) are now available for a blind population without any neuropsychological dysfunctioning. This study utilized the adapted WRAT-R2 and the Comprehensive Vocational Evaluation System (CVES), a neuropsychological test battery adapted for the blind, to investigate the possibility that learning disabilities are present in the adult blind population. Suspected learning disabled, blind subjects were compared with normal blind subjects. There were significant neuropsychological differences between the two groups.

In this dissertation, we study fractal sets and their properties, especially the open set condition, Hausdorff dimensions and Hausdorff measures for certain fractal constructions.

Polymer gels undergo a volume phase transition in solvent in response to an infinitesimal environmental change. This remarkable phenomenon has resulted in many potential applications of polymer gels. The understanding of its mechanical properties has both scientific and technological importance. For this purpose, we have developed a novel method for measuring Poisson's ratio, which is one of the most important parameters determining the mechanical property of gels. Using this method, Poisson's ratio in N-isopropyacrylamide (NIPA) and polyacrylamide (PAAM) gels has been studied.
