'...and one of time.': A Composition for Full Orchestra with Narration

Description: ‘...and one of time.' is a reinterpretation of a small musical moment from Philip Glass' opera, Einstein on the Beach, centered around the phrase "Berne, Switzerland 1905." This reinterpretation is realized through the use of several different compositional techniques including spectral composition, micropolyphony and dodecaphony, as well as the application of extra-musical models developed by Alan Lightman, John Gardner, Italo Calvino and Albert Einstein.

Cassette Systems for Creating Intergeneric Hybrid ATCases

Description: Cassette systems for creating intergeneric hybrid ATCases were constructed. An MluI restriction enzyme site was introduced at the carbamoylphosphate binding site within the pyrB genes of both Pseudomonas putida and Escherichia coli. Two hybrids, E. coli pyrB polar domain fused with P. putida pyrB equatorial domain and P. putida pyrB polar domain fused with E. coli pyrB equatorial domain, are possible. The intergeneric E. coli-P. putida hybrid pyrB gene was constructed and found to encode an active ATCase which complemented an E. coli Pyr- strain. These hybrids are useful for kinetic and expression studies of ATCase in E. coli.

Chemotactic Response of Lumbricus terrestris Coelomocytes to Larval and Adult Stages of Rhabditis pellio

Description: Experiments were performed to assess the suitability of Rhabditis pellio, a nematode found in earthworms, as a challenge organism for use in development of a biomarker assay to determine the potential of chemicals to suppress the immunocompetence of the non-specific immune system. To accomplish this goal, information on the life cycle of R. pellio was determined; including effects of incubation time and temperature on growth rates; along with information on the immune response elicited in the earthworm, Lumbricus terrestris. Immune parameters measured were coelomocyte migration toward and attachment to R. pellio larvae and adults. Preliminary background information showed that R. pellio has potential as a challenge organism for development of a biomarker assay.

Classification of Toolmark Surfaces on Zipper Teeth

Description: This study proposes the classification of the toolmark under the heads of zipper teeth as a subclass characteristic as outlined by the Association of Firearm and Toolmark Examiners (AFTE). Two separate cases in which zipper teeth were found at crime scenes prompted this study. Brass zipper teeth manufactured by YKK were taken from 20 pairs of jeans and studied using a Reichert comparison microscope at 4X power. Photographs were taken and over 750 comparisons made. It was found that the toolmarks on each side on the 20 zippers were unique and independent of all other sides. The observations made in this study indicate that classifying zipper teeth toolmarks as a subclass characteristic is valid.

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques

Description: Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

As Darkness Falls: A Composition for Wind Ensemble

Description: As Darkness Falls is a composition that explores our interaction with several aspects of darkness through the use of musical imagery. The imagery attempts to reflect the moods, feelings, and impressions of a person as he or she interacts with darkness. The non-programmatic character of the composition allows listeners to superimpose their own experiences onto the musical tapestry in order to manifest a personal connection between the listener and the music. As Darkness Falls is a composition scored for a minimum instrumentation of piccolo, 6 flutes, 3 oboes, 3 bassoons, 9 B-flat clarinets, B-flat bass clarinet, 2 E-flat alto saxophones, B-flat tenor saxophone, E-flat baritone saxophone, 4 B-flat trumpets, 4 horns in F, 3 tenor trombones, bass trombone, 2 euphoniums, 2 tubas, timpani, and 4 percussionists. The music consists of three movements (slow-slow-fast) lasting a total of approximately seventeen minutes. The duration of each of the three movements is six minutes, four and one-half minutes, and six and one-half minutes, respectively. The document also contains an analysis of the work by the composer. The analysis explores the compositional style of the work, focusing on musical aspects within each movement that were governing parameters in the compositional process.

Development of a Coaxiality Indicator

Description: The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

The Effects of a Tactile Prompting Device on the Requesting Behavior of a Child with Autism

Description: In the present experiment, a remote control tactile prompting device (RCT) was utilized to prompt a child with autism to recruit teacher models and play suggestions. A multiple baseline and reversal was used to assess the effects of the RCT across three play contexts. The results showed increases in the number of requests for models and suggestions as well as increases in the duration of interactive play between the child and therapist, the number of contextual statements emitted by the child, and the topography and contexts of the play behaviors emitted by the child. Findings are discussed in terms of the effectiveness and generality of the RCT and the issue of teaching a child to recruit versus teaching a child activity-specific behaviors.

The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction

Description: This study examined effects of two response acquisition procedures on topography of responding using the revealed operant technique and compared results to previous experiments on this topic. Subjects emitted 100 repetitions each of 4 response patterns on a continuous schedule of reinforcement. A 30-min extinction condition followed acquisition. One group of subjects learned the first response through a series of shaping steps designed to reduce acquisition variability. Another group of subjects was instructed in the correct response topography and was told there was no penalty for attempting other sequences. The first group of subjects produced high variability during extinction despite reduced variability in acquisition. The second group of subjects responded with moderate to high variability during extinction and little variability during acquisition. Most extinction responses for the first group were variations of the last pattern reinforced. Most extinction responses for the second group were repetitions of the last pattern reinforced.

Elasticity of Money as a Reinforcer: Assessing Multiple Compositions of Unit Price

Description: Behavioral economics is the integration of concepts from micro-economics into behavior analysis. Most of the research in behavioral economics has been done with non-human subjects and with drugs as reinforcers. This study represents an extension of previous research to assess money as a reinforcer with humans as subjects. The participants in this study solved math problems to earn money at various unit prices. Results indicate that demand of money adhered to the law of demand in that consumption decreased as unit prices increased. An underlying assumption is that consumption should be equivalent at different compositions of unit price. Replications of either the same or different compositions of unit price indicated that there were some discrepancies in consumption in this study.

Goal Setting Strategies, Locus of Control Beliefs, and Personality Characteristics of NCAA Division IA Swimmers

Description: The purpose of the present study was to examine goal setting strategies, locus of control beliefs and personality characteristics of swimmers (108 males and 111 females) from top twenty 1999 NCAA Division IA programs. Three questionnaires were completed: (a) Goal Setting in Sport Questionnaire (GSISQ: Weinberg, Burton, Yukelson, & Weigand, 1993), (b) the Internal, Powerful Others, Chance Scale (IPC: Levenson, 1973), and (c) the compliance subscale and six conscientiousness subscales from the NEO Personality Inventory-Revised (NEO PI-R: Costa & McCrae, 1985). Descriptive statistics from the GSISQ indicated that most of the swimmers set goals to improve overall performance (51%) and set moderately difficult goals (58%). Results associated with the IPC scale revealed that most of the swimmers attributed their sport performance to internal factors. Results pertaining to the NEO-PI-R indicated that most swimmers were highly conscientious, disciplined, purposeful, and determined.

Hospitality Students' Attitudes and Behavioral Intentions toward Learning and Using Computer Technology

Description: Following Ajzen/Fishbein's 1980 Theory of Reasoned Action, influences of hospitality students' external variables (age, gender, university classification, and work experience) on computer attitudes, and relationships between computer attitudes and intentions to learn and use computers were tested. A sample of 412 hospitality students completed two measurements: Loyd/Gressard's 1984 Computer Attitude Scale, and Behavioral Intentions to Learn and Use Computers. Males and females had positive computer attitudes. Graduates had more positive computer attitudes. No interaction effect existed between gender and classification. No relationships existed between age and work experience on computer attitudes. Computer attitudes positively correlated with intentions to learn and use computers. Results supported the Theory of Reasoned Action. External variables partially influence attitudes and attitudes influence intentions.

Human Rights & U.S. Foreign Aid, 1984-1995: The Cold War and Beyond...

Description: This study attempts to cast empirical light on the traditionalist-revisionist debate regarding the impact of the Soviet Union's collapse on U.S. foreign policy decision-making. To accomplish this goal, the relationship between human rights and U.S. foreign aid decision-making is examined before and after the Cold War. In doing so, the author attempts to determine if "soft" approaches, such as the use of a country's human rights records when allocating aid, have garnered increasing attention since the end of Cold War, as traditionalists assert, or declined in importance, as revisionists content.

The Implications of National Culture on American Knowledge Work Teams: A Model of a Collaborative Corporate Culture to Support Team Functioning

Description: In order to remain competitive, many American businesses implement team-based work strategies. In many cases, however, teams fail in American organizations, which may be in part due to a conflict between American culture and the cooperative environment necessary for teams to function effectively. By comparing the literature regarding American culture, challenges faced by teams, and then corporate culture, it becomes evident that there are aspects of American culture that pose challenges but also that an appropriate corporate culture can mediate some areas of incompatibility. A collaborative corporate culture can induce cooperation among employees without asking employees to work in a manner that is counterintuitive, thus gaining the benefits of teams.

The Luxury of Tears: A Secondary Survivor's Story

Description: As the written accompaniment for The Luxury of Tears, a twelve-minute documentary video exploring the emotional impact of sexual assault on male survivors and their partners, this document examines the visual texts of both the fiction and nonfiction genres. Specifically, I contend that fiction film manufactures male survivorship with regard to rape events in such manner which contributes to the thematization of social silence. Such silence perpetuates the feminization of rape as a social problem, and dissolves the development of male survivor resources. A discussion of production processes, challenges, and resolutions is included.

"Marvelous Accidents": The Concerto for Prepared Piano and Chamber Orchestra of John Cage

Description: John Cage’s Concerto for Prepared Piano and Chamber Orchestra (1950-51) holds a unique position within the composer’s oeuvre as the first work based in part on chance-derived compositional procedures. Cage entered into such practice gradually, incrementally abandoning subjective taste and personal expression through the course of the work. Drawing from the philosophical framework provided by Cage’s "Lecture on Nothing" (1950) and "Lecture on Something" (c. 1951-52), this thesis explores the aesthetic foundations of the concerto and examines Cage’s compositional methodology throughout its three movements. Special attention is paid to the procedure underlying the first movement, whose analysis is based largely on the composer’s manuscript materials for the work.

A Narrative Analysis of Korematsu v. United States

Description: This thesis studies the Supreme Court decision, Korematsu v. United States, 323 U.S. 214 (1944) and its historical context, using a narrative perspective and reviewing aspects of narrative viewpoints with reference to legal studies in order to introduce the present study as a method of assessing narratives in legal settings. The study reviews the Supreme Court decision to reveal its arguments and focuses on the context of the case through the presentation of the public story, the institutional story, and the ethnic Japanese story, which are analyzed using Walter Fisher's narrative perspective. The study concludes that the narrative paradigm is useful for assessing stories in the law because it enables the critic to examine both the emotional and logical reasoning that determine the outcomes of the cases.

A Narrative Herstory of Women's Studies at the University of North Texas

Description: In the late 1960's the academic field of Women's Studies was created to give women a more equal education and a more accurate reflection of their history and impact on society. At the University of North Texas the effort to implement Women's Studies was not begun seriously until the late 1980's. This paper covers the effort to establish Women's Studies at UNT. My thesis is that this has been a grassroots effort led by professors and students who succeeded not only in establishing Women's Studies but also in changing the face and feeling of the University, creating a more positive environment for women. The bulk of the paper is made up of narrative selections drawn from oral history interviews with key individuals.

Nobody's Fool: A Study of the Yrodivy in Boris Godunov

Description: Modest Musorgsky completed two versions of his opera Boris Godunov between 1869 and 1874, with significant changes in the second version. The second version adds a concluding lament by the fool character that serves as a warning to the people of Russia beyond the scope of the opera. The use of a fool is significant in Russian history and this connection is made between the opera and other arts of nineteenth-century Russia. These changes are, musically, rather small, but historically and socially, significant. The importance of the people as a functioning character in the opera has precedence in art and literature in Russia in the second half of the nineteenth-century and is related to the Populist movement. Most importantly, the change in endings between the two versions alters the entire meaning of the composition. This study suggests that this is a political statement on the part of the composer.

Performing "Camp, Vamp & Femme Fatale": Revisiting, Reinventing & Retelling the Lives of Post-Death, Retro-Gothic Women

Description: This thesis examines the production process for "Camp, Vamp and Femme Fatale," performed at the University of North Texas in April of 1997. The first chapter applies Henry Jenkins's theory of textual poaching to the authors' and cast's reappropriation of cultural narratives about female vampires. The chapter goes on to survey the narrative, cinematic and critical work on women as vampires. As many of the texts were developed as part of the fantasy role-playing game Vampire: The Masquerade, this chapter also surveys how fantasy role-playing develops unpublished texts that can make fruitful ground for performance studies. The second chapter examines the rehearsal and production process in comparison to the work of Glenda Dickerson and other feminist directors.

The Potential of Coelomocyte Chemotaxis as an Immune Biomarker in the Earthworm, Lumbricus terrestris

Description: Coelomocyte migration responses, both random and chemotatic, were examined in the earthworm Lumbricus terrestris. Coelomocyte random migration patterns towards non-stimulatory, non-chemotatic solutions were described. Migration responses to immunostimulatory agents lipopolysaccharides (LPS), N-formly-methionyl-leucyl-phenylalanine (FMLP), sheep erythrocytes, Saccharomyces cerevisiae, Aeromonas hydrophila, Eisenia fetida and Rhabditis pellio were characterized. Chemotaxis was reported to LPS, FMLP, sheep erythrocytes, S. cerivesae and E. fetida. Bio-indicator potential of chemotaxis is discussed relative to variability in migration responses.

The Resurrexit from Hector Berlioz's Messe solennelle (1825): A Case Study in Self-Borrowing

Description: Hector Berlioz's Messe solennelle, his first publicly performed work, was important to his establishment in Paris as a composer. Although he later destroyed the Mass, he reused parts of the Resurrexit movement in three of his later works: Benvenuto Cellini (1836), the Grand messe des morts (1837), and the Te Deum (1849). This study examines the Resurrexit and its subsequent borrowings. In each instance that Berlioz borrowed from the Resurrexit, he extracted large sections and placed them in the context of later works. Each time that borrowing occurred, Berlioz constructed the surrounding music so that portions from the Resurrexit would fit stylistically and a seamlessly into the texture. In each borrowing, he left the melody unaltered, changing harmony and orchestration instead. This pattern of borrowing demonstrates that Berlioz developed his concept of melody early in his career, and that his method of self-borrowing was consistent in each subsequent use of the Resurrexit.
