This dissertation discusses the potential of the snare drum as a solo concert instrument. Four pieces from a collection entitled The Noble Snare are used for demonstration ("Homily" by Milton Babbitt, "Composed Improvisation for Snare Drum" by John Cage, "Peeping Tom" by Dan Senn, and "The Noble Snare" by Stuart Saunders Smith). In the absence of many traditional musical devices (i.e. melody and harmony), alternative means of expression are used by the composer. Each piece is discussed with regard to its distinctive compositional approach and inherent performance issues. Information is also given pertaining to the background of the Noble Snare series. This includes: the inspiration for the project, editorial issues, and its influence on snare drum performance. Much of this research was completed through interviews by with author with Sylvia Smith, publisher of The Noble Snare and owner of Smith Publications.

This study investigated the effects of instructional cues on varied and stereotyped play responses of one typically developing 5-year-old child. Responses were observed across four sets of play materials: blocks, DUPLO® blocks, markers and paints. Training included praise contingent upon forms consistent with the instruction. Two instructions were each trained with corresponding instruction signs, "Try something different" (on blue paper) and "Do the same thing" (on yellow paper) for block and DUPLO block forms. Results show differentiated novel responding during the experimental phase. The same differential effect in marker forms occurred in the sign alone phase. When the sign plus instruction was introduced for painting sessions, novel forms in the same condition discontinued and began to occur in the different condition. These findings suggest stimulus control of behavioral variation and behavioral consistency. The implications for both science and society are discussed.

Living in the United States creates unique challenges in biliteracy and bilingualism for the Arab family. While extant literature provides insight into the literacy interactions and experiences of families from many other cultures now living in the U.S. , there is next to nothing regarding the Arab family literacy experience. Thus, knowledge about the literacy activities Arab families engage in as they gain access to and knowledge of a new culture and language is important. The purpose of this study was to investigate and describe the literacy practices of the Arab families raising bilingual and biliterate children in the U.S. This study , using methodology based on ethnographic approaches, investigated the literacy events, behaviors and interactions which occurred within one Arab family over a 16-week period. A second group of participants were 5 other Arab families living in the U.S. Data sources included video and audio recordings, field notes, observations, journals, informal interviews, and artifacts of children's literacy. The researcher and the participants engaged as co-participants in the research. Findings showed that driving factors behind home literacy practices were religious beliefs and the imminence of return to the home country. Arab mothers were found to yield a heavy influence on …

The purpose of the study was to explore the effects that individual vs. collective structured creative musical problem solving tasks had on students' compositional products. Subjects in a convenience sample of 32 fourth-graders and 32 fifth-graders were randomly assigned to either the individual or collective condition. The 3 treatment sessions were characterized by an open-ended creative problem solving task, which included questions intended to guide subjects through 3 stages of the creative problem solving process: Understanding the Problem, Generating Ideas, and Planning for Action. Subjects participated in the pre- and posttest individually. Three experienced music educators assessed the compositional products in terms of pattern use, cohesiveness, and creativity. The originally intended MANCOVAs could not be carried out because the data did not meet the necessary assumptions. Pretest and posttest scores were explored with individual ANOVAs. The Bonferroni technique was used to adjust the alpha level. The statistical analyses showed that subjects exposed to the individual condition obtained higher scores than subjects exposed to the collective condition on six of the eight explored subtests, but these differences were not significant. The level of interjudge reliability decreased at each of the three measurements of the study: pilot test, pretest, and posttest. The …

The issue of domestic violence continues to be of great concern to society. It is crucial counselors have an understanding of dynamics of domestic violence and the impact it has on victims. Even with heightened awareness of the past decade, the issue continues to be misunderstood, missed altogether by counselors, and sometimes misdiagnosed. This study was created to explore the level of understanding masters level counseling students have of domestic violence, battering behavior, victimization, socioeconomic preconceptions, and counseling victims. Masters level counseling students from the University of North Texas, Denton, TX and staff members of two battered women's shelters from the Dallas, TX area participated in a survey to identify the level of knowing and sensitivity to the issue of domestic violence. Upon completion, an independent t-test was conducted to measure differences in these areas between the two groups. Results indicate a need for counseling students to better understand this issue and implications for client/victims.

To examine if a rhythm can be entrained in either heart rate or oxygen consumption in late stage embryos (days 17-19.5) with light as a zeitgeber, chicken embryos were incubated in complete darkness (D:D) and 12:12 light:dark cycle (L:D). Light had no impact on oxygen consumption (390 µL O2∙min-1∙egg-1) but increased heart rate for non-internally pipped embryos (260 to 270 beats∙min-1 during light cycle). Oxygen consumption increased independent of pipping while heart rate increased (255 to 265 beats∙min-1) in D:D embryos due to pipping. A light-induced rhythm or effect occurred in heart rate but not oxygen consumption, suggesting heart rate and oxygen consumption may be uncoupled.

The study compared outcomes for distance learning courses with those of traditional courses offered by the seven campuses of Dallas County Community College District (DCCCD). The course outcomes were defined as completion rate, dropout rate and success rate. Eleven courses offered during the fall 2003 semester were selected for the study. The methods of instruction employed for each course were traditional classroom lecture/discussion and distance learning formats of Internet, TeleCourse and TeleCourse Plus. Internet courses are delivered on-line, using Internet access and a browser, TeleCourse uses one-way videos or public broadcasting, and TeleCourse Plus is a hybrid between Internet and TeleCourse courses. Seven of the courses selected were part of the core curriculum approved by Texas Higher Education Coordinating Board (THECB) while four other courses were completely transferable. Two types of specific data were extracted: course data and individual student data. Course data included method of instruction, length of course, instructor's load, enrollment, number of withdrawals, and grade distribution. In addition, course requirements including the use of email, videos and Internet, orientation and testing on campus were added as variables. The student data included demographic variables such as age, gender, ethnicity, family status, employment and academic variables including number of …

The purpose of this study was to examine the impact of Core Knowledge curriculum, a Comprehensive School Reform model, on the reading achievement of elementary students located in a north Texas suburban school district. A repeated measures, matched-comparison design was employed using longitudinal data over a three year period. Repeated measures analyses of variance (ANOVA) were conducted to determine if there were any significant differences in student achievement scores as measured by the Texas Assessment of Knowledge and Skills (TAKS) test. The experimental and control school were examined for student achievement gains overall, for advantaged versus disadvantaged students and for achievement gap differences. Although the results of the statistical analyses indicated that there were no significant differences in the reading TAKS scores of students participating in the study, experimental school students consistently had higher mean scores when compared to the control school in all areas. The evaluation of the achievement gap revealed that although the Core Knowledge school did not close the achievement gap between advantaged and disadvantaged students, the disadvantaged students' scores rose in proportion to the advantaged students, thus preventing an increase in the achievement gap between students.

This study investigated whether a relationship exists between learning style and the self-reported technology-related needs, beliefs, stages of adoption, software expertise, and technology competencies of teachers in a large suburban school district. The Gregorc Style Delineator was used to identify dominant learning style, and the Snapshot Survey was used to measure technology-related needs, beliefs, stages of adoption, and software expertise. Technology competencies were measured using the Technology in Education Competency Survey. Data collected from 499 participants was included in data analysis. The study was conducted at each of the 12 elementary schools of a large suburban district in the Dallas-Fort Worth Metroplex. The findings suggest that there is a significant relationship between learning style and the technology-related needs, stages of adoption, software expertise, and competencies of teachers. The relationship between learning style and technology-related needs was significant at the p < .01 level. The relationships between learning style and technology-related stages of adoption, software expertise, and technology competencies were significant at the p < .05 level. Members of the abstract sequential [AS] learning style group reported having significantly fewer needs and significantly higher stages of adoption, software expertise, and competency than members of one or more of the other learning …

The present study examined the relationships of organizational justice and the psychological contract with four outcome variables in a downsizing context. Multinational data were gathered from survivors representing a variety of organizations and industries. The main focus of the current study examined the relationships between survivors' perceptions of procedural, interpersonal, and informational justice and organizational commitment, job satisfaction, turnover intentions, and trust in management. Correlational data indicated that procedural, interpersonal, and informational justice all demonstrated significant correlations with the outcome variables with interpersonal justice demonstrating higher correlations with the outcome variables than procedural justice. Additionally, the results of two structural models indicated that, although both models fit the data equally well, interpersonal justice was the dominant predictor of the outcome variables. Finally, moderated multiple regression analyses indicated that the psychological contract did not act as a moderator on the relationships between the justice and the outcome variables. However, supplemental confirmatory factor analysis suggested that the justice variables might act as a mediator of the psychological contract - outcome variable relationships. Possible explanations of the results as well as implications for practice and future research are provided.

The purpose of this study was to determine the effectiveness of an intervention designed to eliminate damage notification failures in a customer-specific standard operating procedure used by a global logistics company. Process maps identified locations in the process where damage notification failures could most likely occur. A revised process was designed overnight to eliminate as many notification failure points as possible. In addition, a job aid was included to help facilitate the process change for the drivers. The results of the intervention showed a rapid and profound decrease in damage notification failures leading to the retention of a large, profitable account with a minimal initial investment of time and money.

Social and cognitive skill acquisition were evaluated in 33 (male=24, female=11) outpatients with schizophrenia or schizoaffective disorder. A social skills training treatment group (n=19) was compared to a wait-list control (n=14). Participants' mean age was 41 years, mean number of hospitalizations 10.4, and mean number of years with diagnosis 15.8. Assessment measures included WAIS-III Picture Arrangement subtest, Social Cue Recognition Test, COGLAB, WMS-III Word List subtest, and SADS-C. Results did not support the main hypotheses of improved social and cognitive skills in the treatment group. Participants with better memory and attention at pre-testing also did not show an advantage in social skills improvement. Contrary to hypotheses, the control group improved the most on some social and cognitive measures. Several supplemental hypotheses yielded the following results: lack of volunteer participation from paranoid schizophrenia individuals; evidence that schizoaffective disorder participants may be less cognitively impaired and better able to benefit from social skills training; and younger, less chronic participants with better attentional capacities may benefit most from social skills training. Findings are discussed in light of the possibility that improving social skills might not improve social and cognitive functioning, at least with the dosage of social skills training provided in this study. …

A supportive work climate is critical for successful transfer of learning. Influences in the work environment affect the trainee's ability to apply new skills to the job. The supervisor can be a significant figure in the trainee's perception of a supportive transfer climate. Little is known of the effect of supervisor participation in the training on transfer climate. The purpose of this study was to identify differences in trainee and supervisor self-perceptions of the factors affecting transfer climate. Additionally, this study examined the effects of supervisor participation in the training program on perceptions of transfer climate. The participants in this study were trainees in a union-sponsored instructor training program and their supervisors. The study found perception gaps between the overall perception of transfer climate and supervisor support. The level of supervisor participation in the training program was not to be a factor in the differences between the trainee and supervisor perceptions. No statistically significant difference exists in the perception of other transfer climate factors: supervisor sanctions, peer support, resistance/openness to change, and feedback/performance coaching. In addition, the study found that supervisor participation in the training made little difference in the perceptions of transfer climate by supervisors and trainees. Studies comparing …

This study identified transition practices used by teachers and/or primary caregivers of infants and toddlers when entering child care programs across Dallas , TX . Participants completed the Program Entry Transition Practices Survey regarding their use of transition practices in fall 2003 and perceived barriers to entry transition practices. Results show frequency tallies, percentages of use for each transition practice, and the mean number of practices used for the entire sample and with the sample split according to participants from profit and non-profit programs. Results were also organized into four subscales based on the type of practice used. Results supported the hypothesis that teachers and caregivers would report more transition practices occurring after beginning care and directed towards a group than those occurring before beginning care and directed towards an individual. In response to the broader research question regarding barriers: Teachers and caregivers from profit and non-profit centers reported similar barriers to implementing transition practices.

The purpose of the study was to investigate how parents of students with autism perceived individualized education program (IEP) meetings. I determined factors that contributed to the belief held by parents that their children were or were not being properly served by IEP meetings. Parental relationships with educators, IEP meeting experiences, IEP outcomes, and treatment by educators were revealed through participant input. Parents were asked to share their experiences of previous IEP meetings. Additionally, parents provided input regarding practices that school districts could take to improve IEP meetings, and actions that parents could take to serve as better advocates for their children. Research findings indicated that parents did not perceive themselves as being treated as equals during IEP meetings. Parents believed that their input was not valued or welcomed by educators. Not having an equal voice toward their child's education prevented parents from positively influencing outcomes in their child's IEP meetings in terms of obtaining quality services and building positive relations with educators. Parents further revealed that educators failed to implement proper IEP protocol. According to parents, student objectives agreed upon in IEP meetings were often not always fully implemented for students receiving special education services. Research findings concluded that …

This study was designed to determine the effectiveness of culturally responsive child-centered play therapy when compared to a curriculum-based small group counseling intervention as a school-based intervention for Hispanic children experiencing behavioral problems that place them at risk for academic failure. Specifically, this study measured the effects of the experimental play therapy treatment, compared to Kids' Connection, on reducing Externalizing and Internalizing behavior problems of elementary school-age Hispanic children. Twenty-nine volunteer Hispanic children were randomized to the experimental group (n=15) or the comparison group (n=14). Subjects participated in a weekly 30 minute intervention for a period of 15 weeks. Pre- and posttest data were collected from parent and teachers using the Behavior Assessment Scale for Children (BASC). A two factor mixed repeated measures analysis of variance was computed for each hypothesis, to determine the statistical and practical significance of the difference in the pretest to posttest behavior scores of children in the two groups. According to parents' reports, the children receiving play therapy showed statistically significant decreases in externalizing behaviors problems, specifically conduct problems, and moderate improvements in their internalizing behavior problems, specifically anxiety. Teacher BASC results showed no statistical significance and negligible-to- small practical significance between the two groups …

Failure to acknowledge their mental illness occurs in approximately half of all psychotic patients. Interest has been recently been refocused on insight (i.e., awareness of mental illness), and its associations with treatment compliance and better prognosis. Researchers have called into question the traditional factor structure of insight, instead viewing and defining it as a multidimensional and continuous construct. While factor analytic research has suggested that insight is an independent feature of psychotic disorders rather than a secondary manifestation of psychotic symptoms, several factor analytic studies have identified only one higher-order factor. Furthermore, a significant amount of the research literature has assessed insight or analyzed its relationships using only a single insight score. The current study evaluated the structural model of insight and assessed the associations between the different proposed dimensions of insight and psychotic symptoms. One hundred and six participants recruited from both inpatient and outpatient settings with a diagnosis of schizophrenia, schizoaffective disorder, psychotic disorder NOS, or bipolar disorder with psychotic features were rated on David's Schedule for Assessing Insight-Expanded Version (SAI-E), Birchwood's Insight Scale (IS), and the Brief Psychiatric Rating Scale (BPRS) or the Positive and Negative Syndrome Scale (PANSS). Structural equation modeling (SEM) was utilized to provide …

The Rio Gavilan watershed, located in Mexico 's northern Sierra Madre Occidental , has significance in conservation history. Upon visiting the remote, largely un­developed watershed during two hunting trips in the 1930s, renowned conservationist Aldo Leopold thought it was the best picture of land health he had seen. His main indicators of healthy land were slow water runoff rates regulating erosion and historical predator-prey relationships. The visits confirmed Leopold's concept of land health, inspired many of his essays, and helped shape his land ethic. Leopold proposed the area as a control site to research healthy land throughout North America . The proposal never went forward and the area has since been more intensively logged and grazed. This dissertation research used extensive literature review, archives, oral histories, citizen surveys, and rapid assessment of forest, rangeland, riparian, and socioeconomic health to assess impacts of past cultures and update the area's land health status. Projects that could restore land health, such as linked eco-tourism, forest density reduction, and rotational grazing, were assessed for feasibility. Recent critiques of Leopold's land ethic were also reviewed. Results indicate most pre-1940s impacts were light, current land health status is moderate, and local interest exists in restoring land …

This study investigated the effect of cognitive factors on competency to stand trial. Previous researchers have investigated how psychological variables --such as psychosis and intelligence--contribute to incompetency. Although several researchers have established that intelligence contributes to incompetency, very few have investigated the role of specific cognitive abilities within the realm of intelligence. This study investigated the performance of 55 defendants referred for competency restoration on neuropsychological measures. Specifically, competent defendants and incompetent defendants were compared on several measures assessing functioning in seven cognitive domains. Competent defendants performed significantly better than incompetent defendants on measures of verbal comprehension, social judgment, verbal memory, and executive functioning. Competent and incompetent defendants did not differ on attention, visual spatial skills, or nonverbal memory.

The purpose of the present study was to study the relationship of MCMI-III clinical scales with MMPI-2 clusters in a chronic pain population. Data was obtained through assessment data (N = 242) from the Dallas Spinal Rehabilitation Center (DSRC), that included MMPI-2 and MCMI-III, as well as pre-and post-assessment information (n = 21) and follow-up questionnaires (n = 19). Subjects' age ranged from 18 to 64. Each patient had a primary diagnosis related to a back and/or a cervical injury, a chronic pain diagnosis, and often medical prescription dependency and/or addition. Each has experienced back pain in the lumbar region (L1 to L5) or cervical region (C1 to C7) for an average of 32 months. Patients with thoracic (mid-spine) and carpal tunnel pain were excluded from this study. A multivariate cluster analysis procedure was performed that yielded 3 homogeneous female MMPI-2 clusters and 4 MMPI-2 homogeneous male clusters. Seven multiple regression analyses were performed to determine which MCMI-III clinical scales predicted cluster membership in the MMPI-2 clusters. Results indicated that MCMI-III clinical scales "7" Compulsive, "X" Validity and "C" Borderline were predictors for membership in the male MMPI-2 clusters. Membership in the female MMPI-2 clusters were predicted by MCMI-III clinical …

Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made in this area, it remains a fertile area for further development. One application of agents under careful scrutiny is the automated negotiation of conflicts between different user's needs and desires. Many techniques require explicit user models in order to function. This dissertation explores a technique for dynamically constructing user models and the impact of using them to anticipate the need for negotiation. Negotiation is reduced by including an advising aspect to the agent that can use this anticipation of conflict to adjust user behavior.

This thesis will examine the iconography of late-thirteenth- through fifteenth-century images of St. Veronica's veil, also known as vernicles. In the late Middle Ages, vernicle iconography changed from iconic representations of Christ's face toward graphic imagery of Christ's suffering during his Passion. These passionate transformations, as I have called them, were affected by the Roman Sudarium relic, popular devotion to Christ's suffering and humanity during his Passion, and the Catholic ritual of Mass. This thesis will consider how the function of vernicle images during Mass was reflected in their iconography throughout Europe between 1250 and 1500.

Following the terrorist attacks on the United States on September 11, 2001, many turned to the field of psychology for greater understanding of the impact of such events and guidance in supporting our citizens. This study sought to gain greater understanding of the differential impact of the September 11th attack on individuals by investigating the influence of age, psychological hardiness, and repression versus sensitization as forms of coping behavior on psychological health. Both an initial cross-sectional sample (172 young adults & 231older adults) and a short-term longitudinal follow-up (39 young adults & 58 older adults) were included in the study. Older age, psychological hardiness and the use of a repressing coping style were found to each individually relate to greater resilience/less dysfunction at both time one and two. For young adults, high hardy repressors faired best, followed by high hardy sensitizers. Low hardy young adults demonstrated similar levels of dysfunction regardless of coping style (repressions/sensitization). For older adults, coping style impacted both high and low hardy individuals equally, with high hardy repressors demonstrating greater functioning. This study attempted to gain greater insight into explanations for these and previous findings of greater resilience among older adults. In explaining the greater resilience …

The pyrimidine biosynthetic pathway is an essential pathway for most organisms. Previous research on the pyrimidine pathway in Pseudomonas aeruginosa (PAO1) has shown that a block in the third step of the pathway resulted in both a requirement for exogenous pyrimidines and decreased ability to produce virulence factors. In this work an organism with a mutation in the second step of the pathway, aspartate transcarbamoylase (ATCase), was created. Assays for pyrimidine intermediates, and virulence factors were performed. Results showed that the production of pigments, haemolysin, and rhamnolipids were significantly decreased from PAO1. Elastase and casein protease production were also moderately decreased. In the Caenorhabditis elegans infection model the nematodes fed the ATCase mutant had increased mortality, as compared to nematodes fed wild type bacteria. These findings lend support to the hypothesis that changes in the pyrimidine biosynthetic pathway contribute to the organism's ability to effect pathogenicity.
