Keyboard Innovation: Harry Partch's Contributions

Access: Use of this item is restricted to the UNT Community
"Harry Partch's Keyboard Innovation" is a computer-assisted demonstration that introduces the tuning system used primarily by the twentieth-century American composer, Harry Partch. The multimedia product was developed in Director 6.0, and it includes sound and video clips from CDs and videocassettes of Partch's works produced by Phillip Blackburn and distributed by the American Composers Forum. The content of the demonstration involves a 43-tone microtonal tuning system and its application in the music literature. This demonstration will discuss the chronological order in which these prototypes were developed and also includes samples of the tuning of notes in Partch's scale that the novice can experiment with interactively. These tones were synthesized using the Csound scores shown in Appendix B. Materials for this demonstration are based on Harry Partch's Genesis of a Music.

The Application of a Health Service Utilization Model to a Low Income, Ethnically Diverse Sample of Women

Access: Use of this item is restricted to the UNT Community
A model for health care utilization was applied to a sample of low income women. Demographic Predisposing, Psychosocial Predisposing, Illness Level, and Enabling indicators were examined separately for African American (n = 266), Anglo American (n = 200), and Mexican American (n = 210) women. Structural Equation Modeling revealed that for African American and Anglo American women, Illness Level, the only significant path to Utilization, had a mediating effect on Psychosocial Predisposing indicators. The model for Mexican Americans was the most complex with Enabling indicators affecting Illness Level and Utilization. Psychosocial Predisposing indicators were mediated by Illness Level and Enabling indicators which both directly affected Utilization. Implications of the results for future research are addressed.

Prevalence of Undiagnosed Dissociative Disorders in an Inpatient Setting

Access: Use of this item is restricted to the UNT Community
This study examined the prevalence of undiagnosed dissociative disorders in a sample of 201 adult patients admitted to a private psychiatric hospital in a major metropolitan city in the south-central United States, over an eight-month period. A screening measure, two blind structured interviews, and a blind clinical interview were employed. The lifetime prevalence of dissociate disorders among the interviewed subjects was 40.8%. More specifically, 7.5% were diagnosed with dissociative identity disorder, 15.4% with dissociative disorder not otherwise specified, 13.4% with dissociative amnesia, and 4.5% with depersonalization disorder. Dissociative fugue was not found in this sample. Cohen's kappa reliability coefficients were computed between the three interview measures, resulting in significant findings for the presence of dissociative identity disorder and dissociative disorder not otherwise specified versus no dissociative disorder. The Cohen's kappa reliability coefficients were as follows: DDIS-DES-T = 0.81; SCID-D-DES-T = 0.76; Clinician-DES-T = 0.74, DDIS-SCID-D = 0.74; DDIS-Clinician = 0.71, and SCID-D-Clinician = 0.56. A meeting was conducted at the end of all subject interviews to discuss discrepant findings between measures. Four additional sub-analyses were performed between dissociative and non-dissociative subjects on DSM-IV variables. Patients diagnosed with a dissociative disorder had higher rates of comorbid major depressive disorder, borderline personality …

Loading the Problem Loader: The Effects of Target Training and Shaping on Trailer Loading Behavior of Horses in a Natural Setting

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to develop an effective method for trailer loading horses based on the principles of positive reinforcement. Target training and shaping were used to teach trailer loading behavior in a natural setting. Five AQHA mares were selected for this program. All five had been loaded before through the use of punishment. A two-horse trailer was used. Approximations to loading and inappropriate behaviors were the dependent variables. When intervention started the target was moved to various locations inside the trailer. Subjects started training on the left side of the trailer. After a subject was loading in the left side they were moved to the right side, then to loading half on the right and half on the left, then they were loaded by a different trainer, and into a different trailer. For one subject a limited hold was utilized, as well as a companion horse.

Comparative Analysis of Chronic Versus Acute Stressors and Their Influence on Distress Consequences at Work

Access: Use of this item is restricted to the UNT Community
Workplace stress has been found to be a causal agent of psychological distress consequences in employees. Chronic stressors have been well researched, in particular, role conflict, role ambiguity, and work overload have been extensively studied. A meta-analysis was conducted in order to aggregate past research to gain a better understanding of the impact these stressors have on the psychological distress consequences of depression, tension/anxiety, somatic complaints, and generalized feelings of stress. Only role ambiguity was found to be a significant contributor to psychological distress, in particular to feelings of depression and stress. In general, however, effect sizes for all three stressors were moderate to large. While chronic stressors have been well researched, acute stressors have been widely overlooked. Since research in this area is limited, the Daily Work Hassles Survey was developed and validated in order to analyze the role daily hassles play in the workplace. The survey yielded two factors, Interpersonal Hassles and Task Hassles. The former of which was found to be significantly related to the distress consequences of depression, tension/anxiety, somatic complaints, and general feelings of stress. The ultimate goal of this project was to compare chronic and acute stressors. Results from the daily hassles study were …

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 …

Sorry Guard

Access: Use of this item is restricted to the UNT Community
Sorry Guard is a collection of poems with a critical introduction on poetic form. Form in poetry can be revealed vocally (how the poem sounds), temporally (how the poem makes use of time), and spatially (how the poem is visualized, both physically on the page due to typography and imagistically due to the shape and movement of its subject matter). In this preface, I will address these three aspects of form in relation to three distinct twentieth century poets: Robert Hass, W.S. Merwin, and W.H. Auden. I am most interested in how particular formal decisions shape meaning and value in poetry. My aesthetic approach here primarily dwells on what Helen Vendler calls, "the music of what happens." The urgency of Robert Hass's spoken word is important to me because I wish to make poems that should be spoken aloud and remembered. While W.S. Merwin's rejection of punctuation is not my own aesthetic outlook, I strive to achieve through close attention to temporal form the mythic voice of his poemsthe immediacy of his lines and images, especially in his second four books. And Auden's deft use of spatial form is only a small aspect of his remarkable verse. All three poets …

A Study of Graphically Chosen Features for Representation of TREC Topic-Document Sets

Access: Use of this item is restricted to the UNT Community
Document representation is important for computer-based text processing. Good document representations must include at least the most salient concepts of the document. Documents exist in a multidimensional space that difficult the identification of what concepts to include. A current problem is to measure the effectiveness of the different strategies that have been proposed to accomplish this task. As a contribution towards this goal, this dissertation studied the visual inter-document relationship in a dimensionally reduced space. The same treatment was done on full text and on three document representations. Two of the representations were based on the assumption that the salient features in a document set follow the chi-distribution in the whole document set. The third document representation identified features through a novel method. A Coefficient of Variability was calculated by normalizing the Cartesian distance of the discriminating value in the relevant and the non-relevant document subsets. Also, the local dictionary method was used. Cosine similarity values measured the inter-document distance in the information space and formed a matrix to serve as input to the Multi-Dimensional Scale (MDS) procedure. A Precision-Recall procedure was averaged across all treatments to statistically compare them. Treatments were not found to be statistically the same and …

Growing carbon nanotubes by chemical vapor deposition technique.

Access: Use of this item is restricted to the UNT Community
Carbon nanotubes were synthesized in the laboratory using chemical vapor deposition at different methane concentration. I found that a methane concentration of 4 sccm was ideal for well recognizable carbon nanotubes. A higher concentration led to fewer nanotube growth and silicon carbide structure. Coating the sample first with Fe(NO3)3 created a catalyst base on the substrate for the nanotube to adhere and grow on.

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 …

Exogenous Influences and Paths To Activism

Access: Use of this item is restricted to the UNT Community
The focus of this research was to ascertain the indirect effects upon activism of intervening variables and recognized exogenous influences upon activism. In addition, this research also focused upon the differences and similarities of a recruited activist model and spontaneous activist model. Regression and path analysis were used to measure the direct and indirect effects of the exogenous and intervening variables. This research found that when the intervening variables, political interest, political awareness, exposure to media, altruism, and self-interest were introduced to both the recruited and spontaneous models, the direct effects of the variables were enhanced.

Work-family responsiveness in organizations: The influence of resource dependence and institutionalization on program adaptation

Access: Use of this item is restricted to the UNT Community
Changes in workforce demographics, employee sentiments, and working conditions have increased attention on employees' needs to balance the demands of work life and family life. Despite apparent growing interest among companies to be responsive to these needs, the number of companies demonstrating high levels of work-family responsiveness is relatively small. The frameworks of resource dependence theory and institutional theory were used to develop a model to explain differences in work-family responsiveness among for-profit companies. The theoretical models were tested on survey data collected through a stratified random sample of 692 for-profit companies. The data were further enhanced with secondary data sources. While the institutional model explained more variance in work-family responsiveness than the resource dependence model, a model combining both theories best explains work-family responsiveness among for-profit companies. High industry-region diffusion of family-friendly benefits was one of several strong predictors of work-family responsiveness. Also, the greater the proportion of professionals in a company's industry, the greater was the level of work-family responsiveness. Companies that measured effectiveness outcomes were more likely to offer family-friendly benefits. The same was true for companies with more positive assessments regarding the impact of their family-friendly benefits. Organizations that were large, publicly traded, or had human …

The Apologist Tradition: A Transitional Period in Southern Proslavery Thought, 1831-1845

Access: Use of this item is restricted to the UNT Community
Early antebellum defenders of slavery acknowledged that slavery created problems for southern society. They contended, however, that slave society was better and more natural than other forms of social organization. Thomas R. Dew, William Harper, and James Henry Hammond each expressed a social philosophy in which slavery had a crucial role in preserving social order. They argued from the basis of social organicism, the idea that society should have an elite that controlled the masses. For all three men, slavery represented a system of order that helped balance the dangers of democracy. Significantly, however, all three men recognized that the slave system was not perfect, and despite their defense of slavery, argued that it was a human institution and therefore corruptible.

Juvenile Justice Sentencing: Are There Alternatives?

Access: Use of this item is restricted to the UNT Community
Research indicates that states have implemented juvenile justice reforms to enact harsher punishments, to transfer greater numbers and younger juvenile offenders to adult criminal court, and to restrict discretion of the juvenile court judges. Social science studies have found that harsher punishments, transfers to adult criminal court and other measures do not work, but that comprehensive approaches which address the numerous major factors contributing to juvenile offending have been successful. This study examined the legal status of the juvenile justice system by focusing upon ten diverse sample states and analyzed the social science research on factors contributing to juvenile offending and on prevention, treatment, and rehabilitation approaches. The study was accomplished by legal research, qualitative social science research, and analysis of both. Findings indicated: a) state statutes require and allow adult punishment of juvenile offenders, transfer of juvenile offenders to adult criminal court, and direct filing of charges against juveniles in adult criminal court; most states begin these proceedings at age 14, some have no age minimum; b) social science research indicates numerous factors contribute to juvenile offending with most of the factors categorized into the major factors of early antisocial behavior, deviant peers, parents and family, sociomoral reasoning, biological …
