An Analysis of the Composition Process of Bartók's Eight Improvisations on Hungarian Peasant Songs, Op. 20

Access: Use of this item is restricted to the UNT Community
This is a study of Bartók's compositional process as it relates to the Improvisations, Op. 20. The study, which focuses on the analysis of the draft manuscript 50PS1, compares the draft and other relevant sources with the final composition. Bartók's framework for the entire Improvisations is based on a compositional strategy of pairing individual improvisations combined with systematic revision of the draft copy by the introduction of tritones as tonal equivalents and movement by fifths from semitones, to achieve structural coherence in the individual improvisations. The tonic-dominant relationship is used to rearrange the individual improvisations in the draft and tritones as tonal equivalents are used to propel the movement between the improvisations to produce a coherent whole.

Attitudes toward Research and Teaching: Differences Between Faculty and Administrators at Three Saudi Arabian Universities

Access: Use of this item is restricted to the UNT Community
This study is an investigation of the perceived attitudinal differences between administrators and faculty toward research and teaching at three Saudi Arabian universities, King Saud University (KSU), King Fahd University of Petroleum and Minerals (KFUPM), and the Islamic University (IU). The researcher also investigated the effect of several variables, such as rank, university, and academic field on administrators and faculty members' attitudes toward teaching and research. Little Attention has been given to studies that examine the differences between faculty and administrators with regard to their attitudes toward the priorities of teaching and research in Saudi Arabian institutions. Also, little research has been conducted regarding the effects of rank and academic field on faculty attitudes in Saudi Arabian institutions. The author used a mail survey and collected 518 useable responses from a total of 710 questionnaires distributed. Factor analysis, MANCOVA, MANOVA, and ANOVA were the statistical methods employed in data analysis. Five attitudes were identified as a result of factor analysis: (a) attitudes toward teaching; (b) attitudes toward research; (c) mission; (d) promotion; and (e) interest. Results indicated that there was a significant difference between faculty and administrators regarding teaching and resea4rch. Administrators showed stronger attitudes toward teaching than faculty at …

The Cluster Hypothesis: A Visual/Statistical Analysis

Access: Use of this item is restricted to the UNT Community
By allowing judgments based on a small number of exemplar documents to be applied to a larger number of unexamined documents, clustered presentation of search results represents an intuitively attractive possibility for reducing the cognitive resource demands on human users of information retrieval systems. However, clustered presentation of search results is sensible only to the extent that naturally occurring similarity relationships among documents correspond to topically coherent clusters. The Cluster Hypothesis posits just such a systematic relationship between document similarity and topical relevance. To date, experimental validation of the Cluster Hypothesis has proved problematic, with collection-specific results both supporting and failing to support this fundamental theoretical postulate. The present study consists of two computational information visualization experiments, representing a two-tiered test of the Cluster Hypothesis under adverse conditions. Both experiments rely on multidimensionally scaled representations of interdocument similarity matrices. Experiment 1 is a term-reduction condition, in which descriptive titles are extracted from Associated Press news stories drawn from the TREC information retrieval test collection. The clustering behavior of these titles is compared to the behavior of the corresponding full text via statistical analysis of the visual characteristics of a two-dimensional similarity map. Experiment 2 is a dimensionality reduction condition, in …

Conformational Studies of Myosin and Actin with Calibrated Resonance Energy Transfer

Access: Use of this item is restricted to the UNT Community
Resonance energy transfer was employed to study the conformational changes of actomyosin during ATP hydrolysis. To calibrate the technique, the parameters for resonance energy transfer were defined. With conformational searching algorithms to predict probe orientation, the distances measured by resonance energy transfer are highly consistent with the atomic models, which verified the accuracy and feasibility of resonance energy transfer for structural studies of proteins and oligonucleotides. To study intramyosin distances, resonance energy transfer probes were attached to skeletal myosin's nucleotide site, subfragment-2, and regulatory light chain to examine nucleotide analog-induced structural transitions. The distances between the three positions were measured in the presence of different nucleotide analogs. No distance change was considered to be statistically significant. The measured distance between the regulatory light chain and nucleotide site was consistent with either the atomic model of skeletal myosin subfragment-1 or an average of the three models claimed for different ATP hydrolysis states, which suggested that the neck region was flexible in solution. To examine the participation of actin in the powerstroke process, resonance energy transfer between different sites on actin and myosin was measured in the presence of nucleotide analogs. The efficiencies of energy transfer between myosin catalytic domain and actin …

Depression, Anxiety, Self-Esteem, and Coping in Children and Adolescents Newly Diagnosed with Cancer and Children and Adolescents on Cancer Treatment for a Period of Seven Months or Longer

Access: Use of this item is restricted to the UNT Community
Differences in self-reported depression, anxiety, self-esteem, and coping were evaluated in two groups of pediatric oncology patients: newly diagnosed (less than six months post-diagnosis) (n=5) and patients on cancer treatment for seven months or longer (n=5). Participants (6 males, 4 females, ages 7-17 years) completed the Children's Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAIC), and the Culture-Free Self-Esteem Inventory (CFSEI-2); nine of the ten participants discussed in a semi-structured interview their personal experiences and feelings about having cancer. Although the newly diagnosed group had a higher mean score on the CDI than the 7 months or greater group, the difference was not significant (p = .054). The newly diagnosed group also had higher mean state and trait anxiety scores on the STAIC, indicating higher anxiety levels, and a slightly lower CFSEI-2 mean score, indicating slightly lower self-esteem than the 7 months or greater group, but differences were not at a statistically significant level (p>.05).

Empirical Evidence of Pricing Efficiency in Niche Markets

Access: Use of this item is restricted to the UNT Community
Unique and proprietary data of the illiquid, one-year non cancelable for three month Bermudan swaps (1Y NC 3M swaps) and one-year non callable for three months Bermudan CDs (1Y NC 3M CDs), provides evidence of market efficiency. The 1Y NC 3M swap and 1Y NC 3M CD markets efficiently reflected unexpected economic information. The 1Y NC 3M swaption premiums also followed the European one-year into three-month (1Y into 3M) swaption volatilities. Swaption premiums were computed by pricing non-optional instruments using the quoted 1Y NC 3M swap rates and the par value swap rates and taking the difference between them. Swaption premiums ranged from a slight negative premium to a 0.21 percent premium. The average swaption premium during the study period was 0.02 percent to 0.04 percent. The initial swaption premiums were over 0.20 percent while the final swaption premiums were 0.02 percent to 0.04 percent. Premiums peaked and waned throughout the study period depending on market uncertainty as reflected in major national economic announcements, Federal Reserve testimonies and foreign currency devaluations. Negative swaption premiums were not necessarily irrational or quoting errors. Frequently, traders obligated to provide market quotes to customers do not have an interest and relay that lack of …

Evidentiary Value of Condoms: Comparison of Durable Physical and Chemical Characteristics of Condoms

Access: Use of this item is restricted to the UNT Community
Condom trace evidence must not be overlooked in sexual assault cases; understanding the chemical and physical characteristics of condoms is imperative if condoms are to be useful evidence. Previous research shows that condom identification is possible, but it is equally important to evaluate durability of condom residues versus time. Using FT-IR, this study examined vaginal swabs from subjects who self-sampled at intervals for up to 72 hours after having intercourse with a condom. This study investigated whether age and the stage of the menstrual cycle affected the durability of residues in the vagina over time. This study revealed that condoms containing nonoxynol-9, silicone-based lubricants, and particulates provide valuable information for identification, and that nonoxynol-9 specifically withstands the vaginal environment for up to 72 hours. Additionally, age and menstrual cycle both appeared to have an effect on the durability of residues although larger sample size is desirable.

Gunther Schuller and John Swallow: Collaboration, Composition, and Performance Practice in Eine Kleine Posaunenmusik, with Three Recitals of Selected Works by Berio, Bogle, Gregson, Pryor, Suderburg and Others

Access: Use of this item is restricted to the UNT Community
Gunther Schuller is credited with coining the term Third Stream, meaning compositions where twentieth-century art music forms exist simultaneously with jazz. Furthermore, Schuller specifically states in the liner notes to the debut recording of Eine Kleine Posaunenmusik "The work is not a Third Stream piece." Yet the concerto alludes to jazz through a multitude of slide glissandi and plunger mute effects, Solotone mute passages, specific references to the jazz trombone styles of Tommy Dorsey and Lawrence Brown, musical quoting or indirect reference, and the use of a walking bass line in Movement V, Finale. What makes one piece Third Stream and another simply a modern composition with jazz implications? Is Third Stream primarily a compositional designation or a performance practice stipulation? How does a celebrated trombone soloist inspire and collaborate with a distinguished composer in the creation of a major work? The somewhat conspicuous title, Eine Kleine Posaunenmusik, seems to point towards Mozart's famous string serenade Eine Kleine Nachtmusik. What connection to Mozart, if any, does Schuller's title suggest? All of these questions are elucidated in this study through careful investigation and research of Gunther Schuller's Eine Kleine Posaunenmusik. New interviews with John Swallow and Gunther Schuller are included.

Long-Term Care Administrator Licensure and Certification: An Emerging Health Profession

Access: Use of this item is restricted to the UNT Community
The long-term care administrator profession is one that is both new and evolving. The unique historical perspective of this health profession is brief in the number of years it encompasses and crucial in understanding the current issues facing the profession. Administrator experiences provide a point of reference regarding the profession's structural problems. Ethical considerations play a dynamic role in administrators' daily jobs as well as their continued licensure. The significance of the profession's ongoing problems at the state and national level causes the need for alternatives to the current system. A combination of these alternatives must be embraced to assist in the recruitment and retention of long-term care administrators.

Macroinvertebrate Community Structure as an Indicator of Watershed Health in the Upper Trinity River Basin, North Central Texas

Access: Use of this item is restricted to the UNT Community
This study describes macroinvertebrate community structure and assesses its potential in detecting point and non-point sources of disturbance associated with rural and urban areas in the Upper Trinity River Basin. Geospatial techniques were used to quantify landuse within the watershed in a GIS. At rural sites near the headwaters of the Trinity River, collector-gathering burrowers that are adapted to minimal flow comprised the majority of taxa. Destinies of taxa compositions at downstream sites increased and shifted toward psammophilic and rheophilic invertebrates, including primarily collector-filtering clingers, that are characteristic of shifting sand habitats in large prairie rivers. Benthic community structure generally benefited from point source impacts including wastewater treatment plant effluents that maintained higher flow. Community indices were negatively associated with forest landuse and positively associated with urban landuse. Partial CCA determined that flow and landuse contributed equally to species dispersions. Comparisons with historical biomonitoring studies in upper Trinity River Basin indicate improved watershed health.

The Meaning of Elder Abuse

Access: Use of this item is restricted to the UNT Community
Elder abuse first received national attention in 1980, as the subject of a congressional investigation. Now, 20 years later, establishing successful strategies of identification, subsequent intervention, and prevention of abuse is of paramount importance; but progress toward this goal is hindered by lack of consensus as to the definition of elder abuse, and the use of vague, confusing, and sometimes contradictory terms in its discussion. In this paper, both social research and professional approaches and legal approaches to the definition of elder abuse are surveyed, as are definitions formulated for the National Elder Abuse Incidence Study conducted by the National Center on Elder Abuse. The continuing need for a universal or standard definition is emphasized.

Microstructure and Electronic Structures of Er-Doped Si Nano-particles Synthesized by Vapor Phase Pyrolysis

Access: Use of this item is restricted to the UNT Community
Si nanoparticles are new prospective optoelectronic materials. Unlike bulk Si cry-stals, Si nanoparticles display intriguing room-temperature photoluminescence. A major challenge in the fabrication of Si nanoparticles is the control of their size distribution. The rare-earth element Er has unique photo emission properties, including low pumping power, and a temperature independent, sharp spectrum. The emission wavelength matches the transmission window of optical fibers used in the telecommunications industry. Therefore, the study of Er-doped Si nanoparticles may have practical significance. The goals of the research described in this dissertation are to investigate vapor phase pyrolysis methods and to characterize the microstructure and associated defects, particles size distributions and photoluminescence efficiencies of doped and undoped Si nanoparticles using analytical transmission electron microscopy, high resolution electron microscopy, and optical spectroscopy. Er-doped and undoped Si nanoparticles were synthesized via vapor-phase pyrolysis of disilane at Texas Christian University. To achieve monodisperse size distributions, a process with fast nucleation and slow growth was employed. Disilane was diluted to 0.48% with helium. A horizontal pyrolysis oven was maintained at a temperature of 1000 °C. The oven length was varied from 1.5 cm to 6.0 cm to investigate the influence of oven length on the properties of the nanoparticles. …

An Online Academic Support Model for Students Enrolled in Internet-Based Classes

Access: Use of this item is restricted to the UNT Community
This doctoral dissertation describes a research study that examined the effectiveness of an experimental Supplemental Instruction (SI) program that utilized computer-mediated communication (CMC) rather than traditional SI review sessions. During the Spring 1999 semester, six sections of an introductory computer course were offered via the Internet by a suburban community college district in Texas. Using Campbell and Stanley's Nonequivalent Control Group model, the online SI program was randomly assigned to four of the course sections with the two remaining sections serving as the control group. The students hired to lead the online review sessions participated in the traditional SI training programs at their colleges, and received training conducted by the researcher related to their roles as online discussion moderators. Following recommendations from Congos and Schoeps, the internal validity of the groups was confirmed by conducting independent t-tests comparing the students' cumulative credit hours, grade point averages, college entrance test scores, and first exam scores. The study's four null hypotheses were tested using multiple linear regression equations with alpha levels set at .01. Results indicated that the SI participants earned better course grades even though they had acquired fewer academic credits and had, on average, scored lower on their first course …
