Michael Daugherty's Red Cape Tango: A Comparative Study of the Original Version for Symphony Orchestra and its Transcription for Wind Orchestra, with Four Recitals of Selected Works by Beethoven, Dvorák, Verdi, Bartók and Daugherty

Access: Use of this item is restricted to the UNT Community
Michael Daugherty has created his niche in the music world by composing works inspired by icons of American popular culture. Red Cape Tango is the final movement of his Metropolis Symphony, a work inspired by the life and times of the comic book character Superman. This movement in particular deals with the death of the superhero through the use of musical elements, most notably the Latin Sequence of the Mass for the Dead, Dies irae. Daugherty's ingenuity in blending profoundly dark subjects with humor is particularly evident in this work. Death is personified as a temptress and lures Superman through the power of a seductive tango. This study concentrates on Daugherty's compositional style and its impact in musical circles. A transcription for wind orchestra was created by another composer/conductor precisely because of the need to bring such an important work to another medium, thus making it accessible to a wider audience. In addition, this study looks at the changes in instrumentation necessary to create a second, equally formidable version of the work.

Monte Carlo simulation and experimental studies of the production of neutron-rich medical isotopes using a particle accelerator.

Access: Use of this item is restricted to the UNT Community
The developments of nuclear medicine lead to an increasing demand for the production of radioisotopes with suitable nuclear and chemical properties. Furthermore, from the literature it is evident that the production of radioisotopes using charged-particle accelerators instead of nuclear reactors is gaining increasing popularity. The main advantages of producing medical isotopes with accelerators are carrier free radionuclides of short lived isotopes, improved handling, reduction of the radioactive waste, and lower cost of isotope fabrication. Proton-rich isotopes are the result of nuclear interactions between enriched stable isotopes and energetic protons. An interesting observation is that during the production of proton-rich isotopes, fast and intermediately fast neutrons from nuclear reactions such as (p,xn) are also produced as a by-product in the nuclear reactions. This observation suggests that it is perhaps possible to use these neutrons to activate secondary targets for the production of neutron-rich isotopes. The study of secondary radioisotope production with fast neutrons from (p,xn) reactions using a particle accelerator is the main goal of the research in this thesis.

Gender and Desire in Thomas Lovell Beddoes' The Brides' Tragedy and Death's Jest-Book

Access: Use of this item is restricted to the UNT Community
Thomas Lovell Beddoes' female dramatic characters are, for the most part, objectified and static, but these passive women perform a crucial narrative and thematic function in the plays. Alongside the destructive activity of the male characters, they dramatize masculine-feminine unions as idealized and contrived and, thus, unstable. Desire, power and influence, as well as the constrictive aspects of physicality, all become gendered concepts in Beddoes' plays, and socially normative relationships between men and women, including heterosexual courtship and marriage, are scrutinized and found wanting. In The Brides' Tragedy, Floribel and Olivia, the eponymous brides, represent archetypes of innocence, purity, and Romantic nature. Their bridegroom, Hesperus, embodies Romantic masculinity, desiring the feminine and aspiring to androgyny, but ultimately unable to relinquish masculine power. The consequences of Hesperus' attempts to unite with the feminine other are the destruction of that other and of himself, with no hope for the spiritual union in death that the Romantic Hesperus espouses as his ultimate desire. Death's Jest-Book expands upon the theme of male-female incompatibility, presenting heterosexual relationships in the context of triangulated desire. The erotic triangles created by Melveric, Sibylla, and Wolfram and Athulf, Amala, and Adalmar are inherently unstable, because they depend upon the …

Breaking Through: A Composition for Symphony Orchestra

Access: Use of this item is restricted to the UNT Community
Breaking Through is a single-movement composition for symphony orchestra based on a fourteen-note melody. Every harmonic and melodic figure except the bass line is derived from this source melody. The structure of the work is based on a number of musical dichotomies that work on both local and large-scale levels. The local dichotomies contrast consonance with dissonance and ambiguity with clarity (in respect to texture and rhythm). The dichotomy of two-part form versus three-part form and the dichotomy of simplicity versus complexity operate on the large scale. The unity lended by the single source melody coupled with the contrasts furnished by the aforementioned dichotomies allow Breaking Through to be both coherent and interesting.

Changing Privacy Concerns in the Internet Era.

Access: Use of this item is restricted to the UNT Community
Privacy has always been a respected value regardless of national borders, cultural differences, and time in every society throughout history. This study focuses on the unprecedented changes in the traditional forms of privacy and consequent concerns with regard to invasion of privacy along with the recent emergence and wide use of the Internet. Government intrusion into private domains through the Internet is examined as a major concern. Privacy invasions by Web marketers, hacker threats against privacy, and employer invasion of employee privacy at the workplace are discussed respectively. Then a set of possible solutions to solve the current problems and alleviate the concerns in this field is offered. Legal remedies that need to be performed by the government are presented as the initial solution. Then encryption is introduced as a strong technical method that may be helpful. Finally, a set of individual measures emphasized as complementary practical necessities. Nevertheless, this study indicates that technology will keep making further changes in the form and concerns of privacy that possibly may outdate these findings in the near future, however, privacy itself will always remain as a cherished social value as it has always been so far.

Effects of Hedonic and Utilitarian Shopping Satisfaction on Mall Consumption

Access: Use of this item is restricted to the UNT Community
The modern consumer expects a consumption experience with both hedonic and utilitarian rewards during a single visit to the mall. The orchestrating of both hedonic and utilitarian benefits in one visit challenges mall management and retailers to deliver the maximum shopping experience. This study seeks to reveal relationships among six variables: demographic characteristics, mall shopping orientation, mall perception, hedonic satisfaction, utilitarian satisfaction, and mall consumption. The intercept survey was conducted at a major entertainment-themed mall in north Texas. Multiple regression analyses (N = 202) indicate that demographic characteristics and mall shopping orientation were significant predictors of mall perception. Also, two mall perception factors (Sensation and Physical Environment) were predictors of hedonic and utilitarian mall shopping satisfaction. However, hedonic and utilitarian mall shopping satisfaction were found not to predict mall consumption in terms of cross-shopping, money spent, and time spent.

Use of Satellite Imagery and GIS to Model Brood-Rearing Habitat for Rio Grande Wild Turkey Populations Occurring in the Western Cross Timbers Region of Texas

Access: Use of this item is restricted to the UNT Community
Remote sensing and GIS have become standard tools for evaluating spatial components of wildlife habitats. These techniques were implemented to evaluate Rio Grande wild turkey (Meleagris gallopavo) poult-rearing habitat in the Western Cross Timbers region of Texas. Texas Parks and Wildlife (TPWD) random roving turkey counts for 1987-1989 and 1998-2000 were selected, indicating locations where hens with poults were observed. Satellite imagery from 1988 and 1999 was classified and then processed with Patch Analyst. To add robustness, stream, road and census population densities were also evaluated for each turkey location. Analysis of the 1988 canopy cover image, comparing observed locations with randomly-selected habitat cells (N = 20) indicated significant differences (p <.05) for patch edge variables. Mean patch edge was significantly greater for habitat locations where hens with poults were observed than for those selected at random. Spatial data for 1999 did not indicate a significant difference (p < .05) between sampling groups (observed vs. random, N = 30). Significant differences (p <.05) did occur for turkey locations observed in both 1988 and 1999 (N = 7). This demonstrates the adaptability of wild turkey hens, as habitats change over time, hens continued to visit the same locations even though the …

Developing a Test Bed for Interactive Narrative in Virtual Environments

Access: Use of this item is restricted to the UNT Community
As Virtual Environments (VE) become a more commonly used method of interaction and presentation, supporting users as they navigate and interact with scenarios presented in VE will be a significant issue. A key step in understanding the needs of users in these situations will be observing them perform representative tasks in a fully developed environment. In this paper, we describe the development of a test bed for interactive narrative in a virtual environment. The test bed was specifically developed to present multiple, simultaneous sequences of events (scenarios or narratives) and to support user navigation through these scenarios. These capabilities will support the development of multiple users testing scenarios, allowing us to study and better understand the needs of users of narrative VEs.

The Effect of Web-Based Support as an Adjunct to a Self-Help Smoking Cessation Program

Access: Use of this item is restricted to the UNT Community
For the past quarter century, the public has been educated and warned about the dangers of smoking, and both smokers and health researchers have been in search of cost-effective, smoking cessation programs that will lead to long-term cessation. This study used a randomized experimental design to investigate the effectiveness of adding Web-based support materials to a nationally sponsored self-help smoking intervention. There was no significant increase in abstinence rates nor progression through the stages of change by those participants who had access to the Web site. However, there were some overall significant trends that suggested these self-help interventions were successful at decreasing daily rates of smoking and nicotine dependency, as well as tended to encourage repeated quit attempts. Although Web-based supports did not appear to increase the effectiveness of the nationally sponsored self-help intervention, this study demonstrated overall 12 week follow-up abstinence rates of 30-32%--greater than what might be expected, given average success rates of other self-help interventions. This study also supports the notion that women may face additional barriers to smoking cessation. Limitations and implications for future research are discussed.

The Cross-Validation of AD/HD Instruments and the Relationship to Neurocognitive and Behavioral Measures

Access: Use of this item is restricted to the UNT Community
The purpose of this study was twofold: to determine the construct validities of comparable AD/HD instruments that were developed according to our current, DSM-IV classification system for AD/HD; and to identify potential +neurocognitive and socioemotional markers for AD/HD. The sample consisted of 145 children ages 8 to 11 years of age who were diagnosed with Attention Deficit Hyperactivity Disorder (AD/HD), or Central Auditory Processing Disorder (CAPD). Children were administered a battery of neurocognitive tests and completed a self-report measure of personality. Parents completed several, AD/HD instruments pertaining to their children. The AD/HD instruments used in this study were the Attention Deficit Disorder Evaluation Scale-Home Version (ADDES), Attention Deficit Hyperactivity Disorder Test (ADHDT), and the Attention Problems and Hyperactivity scales from the BASC-Monitor (BASC-M). Of interest was how each AD/HD instrument compared to the DSM-IV, particularly in terms of the cross-consistency of AD/HD subtype classifications. The findings showed that the AD/HD instruments classified participants differently from the initial, DSM-IV entry diagnosis. Rates of agreement were better for some of the AD/HD instruments than for others yet there was little overall consistency. The neurocognitive measures used in the study were the Cognitive Assessment System-Basic Battery scales. The socioemotional measures used in the …

Phosphorus Retention and Fractionation in Masonry Sand and Light Weight Expanded Shale Used as Substrate in a Subsurface Flow Wetland

Access: Use of this item is restricted to the UNT Community
Constructed wetlands are considered an inefficient technology for long-term phosphorus (P) removal. The P retention effectiveness of subsurface wetlands can be improved by using appropriate substrates. The objectives of this study were to: (i) use sorption isotherms to estimate the P sorption capacity of the two materials, masonry sand and light weight expanded shale; (ii) describe dissolved P removal in small (2.7 m3) subsurface flow wetlands; (iii) quantify the forms of P retained by the substrates in the pilot cells; and (iv) use resulting data to assess the technical and economic feasibility of the most promising system to remove P. The P sorption capacity of masonry sand and expanded shale, as determined with Langmuir isotherms, was 60 mg/kg and 971 mg/kg respectively. In the pilot cells receiving secondarily treated wastewater, cells containing expanded shale retained a greater proportion of the incoming P (50.8 percent) than cells containing masonry sand (14.5 percent). After a year of operation, samples were analyzed for total P (TP) and total inorganic P (TIP). Subsamples were fractionated into labile-P, Fe+Al-bound P, humic-P, Ca+Mg-bound P, and residual-P. Means and standard deviations of TP retained by the expanded shale and masonry sand were 349 + 169 and 11.9 …

The Piano as an Orchestra: The Accompanist and the Twentieth-Century Orchestral Reduction

Access: Use of this item is restricted to the UNT Community
The musical developments of the 20th century have expanded the role of the accompanist. As the compositional output of our time increases, and the opportunity to perform as soloist with an orchestra diminishes, piano reductions of an orchestral score are becoming the most frequent vehicle for concerto performances of twentieth and twenty-first century instrumental literature. While the current state of research provides solid support to many accompanists, it is in the area of instrumental accompanying, especially with regard to the challenges of playing a reduction of an orchestral score with an instrumental soloist, that the lack of discourse becomes strikingly evident. It is the goal of this study to provide the instrumental accompanist with concrete, practical approaches and considerations in order to perform an orchestral reduction in a manner consistent with the integrity of the score. Problems such as identifying the represented orchestral instruments, delineating importance of musical lines, and basic uses and misuses of pedal, articulation, and rubato are discussed. The pianist is led through ways of deciphering and negotiating specific passages, in order to guide the accompanist through the possible pitfalls and challenges unique to many orchestral reductions. By focusing on twentieth century reductions, providing examples of problems …

The compositions of Fisher Aubrey Tull are widely performed and many have become standard repertoire. Tull's compositions encompass a multiplicity of performance media including works for orchestra, chorus, symphonic band, jazz band, brass choir, and solo and chamber works. Tull's compositional output for the trumpet is prolific and is acknowledged to be music of high quality. An examination of Trumpet and Brass Programs, compiled and published annually by the International Trumpet Guild, shows Tull's solo and ensemble works for trumpet to be frequently performed. Furthermore, his compositions for trumpet have been performed and recorded by internationally acclaimed artists including Vincent DiMartino, Terry Everson, Håkan Hardenberger, Anthony Plog, Carl "Doc" Severinsen and Allen Vizzutti.This study investigates Fisher Tull's eight solo works for trumpet, which include: Vignette for Trumpet and Piano (1954); Concerto No. 1 for Trumpet and Orchestra (1964); Concerto No. 2 for Trumpet and Band (1974); Three Bagatelles for Trumpet and Piano (1975); Eight Profiles for Solo Trumpet (1978); Rhapsody for Trumpet and Band (1980); Sonata for Trumpet and Piano (1986); and Chromutations for Solo Trumpet (1988).

Implementation of Scalable Secure Multicasting

Access: Use of this item is restricted to the UNT Community
A large number of applications like multi-player games, video conferencing, chat groups and network management are presently based on multicast communication. As the group communication model is being deployed for mainstream use, it is critical to provide security mechanisms that facilitate confidentiality, authenticity and integrity in group communications. Providing security in multicast communication requires addressing the problem of scalability in group key distribution. Scalability is a concern in group communication due to group membership dynamics. Joining and leaving of members requires the distribution of a new session key to all the existing members of the group. The two approaches to key management namely centralized and distributed approaches are reviewed. A hybrid solution is then provided, which represents a improved scalable and robust approach for a secure multicast framework. This framework then is implemented in an example application of a multicast news service.

Developmental Stressors and Associated Coping Skills in the Development of Disordered Eating in College Females

Access: Use of this item is restricted to the UNT Community
There is a lack of clarity in the current literature in how potential etiological factors interact and result in disordered eating. The purpose of this study was to examine an expanded model of Personality, Social Support, Appraisal/Coping Processes, Abuse History, Internalization of Sociocultural Standards, Psychological Disturbances, and Body Disparagement in the development of disordered eating. The current model was evaluated using 276 women in their transition to college, a time period highly associated with symptoms believed to increase a woman's risk for the development of disordered eating including perceived difficulty coping, weight gain, and negative affect. Structural equation modeling was used to allow simultaneous examination of the causal relationships between the factors. Structural analyses confirmed that college women with previous stressful experiences appraised the adjustment to college as more stressful and reported feeling less able to cope with the transition. Those women who identified the transition as overwhelming were also aware of increased negative mood and psychological states since beginning the school semester. Further, women with previous traumatic sexual experiences appeared to be at additional risk for increased negative affective symptoms. The resulting model confirmed that those women who experience negative mood states and those that endorse strong internalization of …

Application of Thermomechanical Characterization Techniques to Bismuth Telluride Based Thermoelectric Materials

Access: Use of this item is restricted to the UNT Community
The thermoelectric properties of bismuth telluride based thermoelectric (TE) materials are well-characterized, but comparatively little has been published on the thermomechanical properties. In this paper, dynamic mechanical analysis (DMA) and differential scanning calorimetry data for bismuth telluride based TE materials is presented. The TE materials' tan delta values, indicative of viscoelastic energy dissipation modes, approached that of glassy or crystalline polymers, were greater than ten times the tan delta of structural metals, and reflected the anisotropic nature of TE materials. DMA thermal scans showed changes in mechanical properties versus temperature with clear hysteresis effects. These results showed that the application of DMA techniques are useful for evaluation of thermophysical and thermomechanical properties of these TE materials.

Computer Crime as a Barrier to Electronic Commerce: New Solutions for Public Law Enforcement.

Access: Use of this item is restricted to the UNT Community
Electronic commerce was expected to grow exponentially, but the actual rate of growth in recent years has been disappointing. Recent surveys of perceptions of the development of electronic commerce clearly focus our attention on the perception and fear of computer crime as the major cause of this disappointing growth pattern. The thesis critiques existing private law solutions to this problem and argues from a normative theory on “the commons” for the application of new public law enforcement solutions in the public trust, sanctions, and public coproduction of order. The thesis argues that given the failures of existing private law solutions to the problem, these public law enforcement solutions should be more effective, efficient, and more satisfactory.

Fabrication of MOS capacitor and transitor structure using contact photolithography.

Access: Use of this item is restricted to the UNT Community
This problem in lieu of thesis report describes a practical photolithographic method to produce micro patterns on metal-oxide-semiconductor or metal-oxide-semiconductor-metal layers for electrical measurements. The desired patterns are then transferred from the photo mask to the photoresist-coated metal film by exposure, followed by wet etching. In the procedure described in this report, it was observed that microstructures as small as 27 mm with an edge roughness of ~ 2 mm can be reproducibly generated with this process. MOS capacitors and transistors structures can be fabricated by using this technique. The method described in this report requires access to only simple facilities so that it is relatively inexpensive, and the overall time required for the whole process is short.
