The Effect of Individual Versus Collective Creative Problem Solving Experiences on Fourth- and Fifth-grade Students' Compositional Products.
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 …

Refactoring FrameNet for Efficient Relational Queries
The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.

Journey for Jazz
This written thesis accompanies a 32-minute documentary video, Journey for Jazz, which explores four Korean students who major in jazz at the University of North Texas in Denton. Detailed accounts of the pre-production, production, and post-production of the video guide the reader to understand the challenging and rewarding process of making this documentary. Theoretical issues are also discussed, including Bill Nichols's typology of documentary modes as a useful tool for analysis of hybrid documentaries and conventions of the observational and interactive mode in Journey for Jazz, which is considered a hybrid of both modes. The film focuses mainly on the scholarly and artistic experiences that the four students undergo while studying jazz in the United States.

An Analytical Study of the Variations on the Theme of Paganini's Twenty-Fourth Caprice, Op. 1 by Busoni, Friedman, and Muczynski
The purpose of this study is to analyze sets of variations on Paganini's theme by three twentieth-century composers: Ferruccio Busoni, Ignaz Friedman, and Robert Muczynski, in order to examine, identify, and trace different variation techniques and their applications. Chapter 1 presents the purpose and scope of this study. Chapter 2 provides background information on the musical form "theme and variations" and the theme of Paganini's Twenty-fourth Caprice, Op. 1. Chapter 2 also deals with the question of which elements have made this theme so popular. Chapters 3,4, and 5 examine each of the three sets of variations in detail using the following format: theme, structure of each variation, harmony and key, rhythm and meter, tempo and dynamics, motivic development, grouping of variations, and technical problems. Chapter 6 summarizes the findings from this study and attempts to compare those elements among the three variations. Special attention is given to the application of the motivic cells, which are drawn from the original Paganini theme, in the development of succeeding variations. This study shows how these motivic cells contribute to the construction of new motives and melodies in each variation. Additionally, this study attempts to examine each composer's efforts in expanding variation procedure …

Rhapsody for Piano and Small Orchestra
Rhapsody for Piano and Small Orchestra is a one-movement composition in a concerto fashion for seventeen players, and is about nine minutes in duration. The overall form of this work is A B C D E D1 C1 B1 A1. This work contains various hidden compositional devices such as the golden section principle and a palindrome structure. These devices are applied not only to the structure of the work, but also to the pitch related and rhythm-related matters. Also, certain melodic and rhythmic cells are employed for each section in the developmental procedure of that section almost exclusively. Since this work is a concerto-like piece, there are two cadenza-like passages for the piano with an accompanying solo instrument, which plays the obbligato passage. The following essay addresses the form, pitch materials, harmony, rhythm and technical difficulties, orchestration, and variant elements between the corresponding sections used in this work.

An Analysis of the Characteristics of Female Juvenile Offenders as Predictors of Resocialization or Recidivism.
Because there has been a paucity of research on the educational needs of females with academic, behavioral, and emotional problems involved with the juvenile justice system, this study has been an attempt to classify and compare specific characteristics of this population. In particular, it examined their demographics, disability prevalence rates, along with academic, behavioral, and emotional functioning levels, in order to further understand their relationship to the resocialization or recidivism of the different groups of female juveniles incarcerated in the state of Texas, and contribute to the research for further developing successful prevention and intervention programs. Various demographic factors of the female juveniles in this study were examined: (a) offender type, (b) county of commitment, (c) race/ethnicity, (d) age at first referral, and (e) English language proficiency. Prevalence rates of special education disabilities were determined. Academic functioning was measured by (a) IQ; (b) last school grade completed; (c) Test of Adult Basic Education (TABE) reading gain score; and (d) TABE math gain score. Behavioral functioning was indicated through (a) offense history, (b) documented behavior incidents, and (c) total risk score. Emotional functioning included DSM-IV diagnoses and treatment needs. Due to the design of the research being a descriptive exploration, the …

Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing
The Rocker b Ranch on the southern Rolling Plains has one of the last sizeable populations of pronghorn (Antilocapra americana) in Texas. To investigate habitat utilization on the ranch, pronghorn were fitted with GPS/VHF collars and were released into pastures surrounded by a variety of fences to determine how fence types affected habitat selection. Habitat parameters chosen for analysis were vegetation, elevation, slope, aspect, and distances to water, roads, and oil wells. Results showed that pronghorn on the ranch crossed modified fencing significantly less than other types of fencing. Pronghorn selected for all habitat parameters to various degrees, with the most important being vegetation type. Habitat selection could be attributed to correspondence of vegetation type with other parameters or spatial arrangements of physical features of the landscape. Seasonal differences in habitat utilization were evident, and animals tended to move shorter distances at night than they did during daylight hours.

Understanding and preventing police use of excessive force: An analysis of attitudes toward police job satisfaction and human rights laws.
Although governments try to create strict policies and regulations to prevent abuses, use of excessive force is still a problem for almost every country including Turkey. This study is intended to help Turkish National Police administrators to understand and prevent police use of excessive force. Studies on police brutality categorize three factors that explain why police officers use excessive force; these are individual, situational and organizational. In addition to brutality theories, job satisfaction literature is examined in this study to understand the use of excessive force. Job satisfaction is found to be related with burnout, turnover, stress, commitment, and performance. The impact of officers' attitude toward the criminal justice system and/or laws has not been tested widely. Police officers attitudes toward human rights laws are examined in this study to measure its impact on attitude toward use of excessive force. A secondary data collected in Turkey are analyzed by structural equation modeling which provides confirmatory factor analysis, path analysis, and causal relationships between variables. It is found that police officers' attitude toward human rights laws is a significant predictor of their attitudes toward use of excessive force. Job satisfaction and education level are the other significant variables affecting attitude toward …

The Russian trumpet sonata: a study of selected representative sonatas for trumpet and piano with an historical overview of the Russian trumpet school
The impact of training on virtual team effectiveness was assessed in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. A 12-page survey was developed exploring all aspects of virtual teams. 180 surveys were distributed, 52 were returned representing 43 companies. Training led to higher effectiveness in planning tasks and setting goals, solving problems and making decisions, and conflict resolution, but not in communication and responding to customer requirements. Training may not solve all the problems that virtual teams will encounter; however, training will make the challenges easier to handle.

Perturbation of renewal processes
Renewal theory began development in the early 1940s, as the need for it in the industrial engineering sub-discipline operations research had risen. In time, the theory found applications in many stochastic processes. In this thesis I investigated the effect of seasonal effects on Poisson and non-Poisson renewal processes in the form of perturbations. It was determined that the statistical analysis methods developed at UNT Center for Nonlinear Science can be used to detect the effects of seasonality on the data obtained from Poisson/non-Poisson renewal systems. It is proved that a perturbed Poisson process can serve as a paradigmatic model for a case where seasonality is correlated to the noise and that diffusion entropy method can be utilized in revealing this relation. A renewal model making a connection with the stochastic resonance phenomena is used to analyze a previous neurological experiment, and it was shown that under the effect of a nonlinear perturbation, a non-Poisson system statistics may make a transition and end up in the of Poisson basin of statistics. I determine that nonlinear perturbation of the power index for a complex system will lead to a change in the complexity characteristics of the system, i.e., the system will reach …

Access:
Use of this item is restricted to the UNT Community
Baeyer-Villiger oxidation of 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction product was established unequivocally via single crystal X-ray diffraction. Baeyer-Villiger oxidation of 1,9-dibromo-PCU-8,11-dione using ceric ammonium nitrate (CAN) was also performed and afforded a mixture of lactones. Only one of these lactones, which also contained an alkene functionality, could be isolated and characterized. 1,7-dibromo-PCU-8,11-dione was also reacted with CAN, yielding the mono-lactone, which has also been characterized.

Makeshift Information Constructions: Information Flow and Undercover Police
This dissertation presents the social virtual interface (SVI) model, which was born out of a need to develop a viable model of the complex interactions, information flow and information seeking behaviors among undercover officers. The SVI model was created from a combination of various philosophies and models in the literature of information seeking, communication and philosophy. The questions this research paper answers are as follows: 1. Can we make use of models and concepts familiar to or drawn from Information Science to construct a model of undercover police work that effectively represents the large number of entities and relationships? and 2. Will undercover police officers recognize this model as realistic? This study used a descriptive qualitative research method to examine the research questions. An online survey and hard copy survey were distributed to police officers who had worked in an undercover capacity. In addition groups of officers were interviewed about their opinion of the SVI model. The data gathered was analyzed and the model was validated by the results of the survey and interviews.

Problems Encountered in Money Laundering Investigations
The purpose of this study is to identify how the U.S. is responding to money laundering and what kind of problems arise while countering it, beginning with a detailed description of money laundering, its stages, typologies, impacts, and complications. Due to the broad nature of this subject only three main issues form the focal point of this study: problems concerning the banking industry and other financial organizations, problems resulting from the limitations of law enforcement agencies, and problems arising from the lack of cooperation between and within financial institutions and law enforcement agencies. Several probable solutions to the above problems are identified: Considering the financial industry, there are loopholes in the Bank Secrecy Act (BSA) and in other regulations that apply to the industry. Thus, there is a comparison of the Subjective Model vs. Objective Model in terms of reporting systems for financial organizations. On the law enforcement side, the priority is the need to update and upgrade their technology and investigation mechanisms in order not to fall behind the criminals. Finally, cooperation is something that can be achieved through mutual respect and understanding of the priorities of each side, which can be achieved by the creation of an upper …

An investigation of factors affecting Omani faculty members' adoption of information and computing technology.
The purpose of this study was to explore the factors influencing information and computing technology (ICT) adoption for Omani faculty members from a framework of Rogers' theory of diffusion of innovation. Three hundred Omani faculty members from Sultan Qaboos University (SQU) participated in the study. The survey consisted of five parts: (a) an 18-item questionnaire on ICT uses and skills, (b) a 1-item questionnaire on adopter category, (c) a 44-item self-constructed questionnaire on perception of barriers to adopting ICT, (d) a 50-item questionnaire on ICT attributes adapted from Moore and Benbasat, and (e) a 15-item questionnaire on demographic and job-related variables. Descriptive statistics indicated that the faculty members overall used ICT at the "Sometimes" level and had ICT skills at the "Intermediate" level. The most frequently used and skillful ICT functional areas were Website browsing, Internet search engine, and word processing. One-way ANOVAs found significant group differences of ICT uses and skills, perception of barriers, and perception of ICT attributes in the category of adopter. Early adopters used ICT more, had higher ICT skills, perceived fewer barriers in the adopting process, and recognized higher values of ICT attributes than later adopters did. Multiple regression analysis showed the level of ICT …

Preservice teachers' attitudes toward and knowledge about cooperative learning in Kuwait: A quasi-experimental study
The issue of developing effective teacher preparation and professional programs by providing effective teaching and learning strategies to prepare teachers to teach in more challenging ways and change their old ways of teaching to more powerful ones has gained great attention around the world. Cooperative learning was one of the astonishing strategies introduced by many researchers to prepare effective teachers and to solve many educational problems. Teacher educators have taken different approaches to help teachers learn and change in powerful ways. They have focused on the knowledge and attitudes of teachers in promoting their adoption of new practices through educational courses, workshops, and training. After introducing the cooperative learning strategy through a training workshop, this study investigated the knowledge of and attitude of teachers at the College of Basic Education (CBE) in Kuwait towards cooperative learning as a new teaching and learning strategy. The literature reviewed the historical and practical use, theoretical roots, different models, and outcomes of cooperative learning. In addition, (1) teachers' knowledge and attitudes as factors affecting implementation and (2) preservice teacher preparation and training in the use of cooperative learning were reviewed. An attitude survey and a knowledge test were developed based on Bouas, (1993) survey …

Financial Transfer and Its Impact on the Level of Democracy: A Pooled Cross-Sectional Time Series Model.
This dissertation is a pooled time series, cross-sectional, quantitative study of the impact of international financial transfer on the level of democracy. The study covers 174 developed and developing countries from 1976 through 1994. Through evaluating the democracy and democratization literature and other studies, the dissertation develops a theory and testable hypotheses about the impact of the international variables foreign aid and foreign direct investment on levels of democracy. This study sought to determine whether these two financial variables promote or nurture democracy and if so, how? A pooled time-series cross-sectional model is developed employing these two variables along with other relevant control variables. Control variables included the presence of the Cold War and existence of formal alliance with the United States, which account for the strategic dimension that might affect the financial transfer - level of democracy linkage. The model also includes an economic development variable (per capita Gross National Product) to account for the powerful impact for economic development on the level of democracy, as well as a control for each country's population size. By addressing and the inclusion of financial, economic, strategic, and population size effects, I consider whether change in these variables affect the level of …

Higher Education and Entrepreneurship: The Relation between College Educational Background and Small Business Success in Texas
This study examined the relationship between success of small businesses and the educational backgrounds of their owners. A survey composed of questions concerning demographics, educational backgrounds, and business success was mailed to 1100 businesses in Dallas, Denton, and Tarrant counties in Texas. There were 228 usable responses which were analyzed by using the Statistical Package of Social Sciences (SPSS12). Data were sorted so that educational level, sales volume, number of employees, and longevity, were identified on a 5-point ordinal scale. Educational major was identified on a 5-point nominal scale. Pearson's correlation was used to determine whether relationships existed between founders' educational background and small business success. Spearman's correlation was used to determine the direction and strength of the relationships. Then educational level and major were combined with age, gender, ethnicity, and industry, to determine the relationships between founders' educational background, and business success. For this purpose a canonical correlation was used. Five opinion questions concerned influence of college education on business success among college graduates and non-college graduates were identified on a 5-point Likert scale and tested using one-way ANOVA, and independent sample t-test. When educational level and major were the only predictors of business success, a statistically significant relationship …

Use of the Beck Depression Inventory in Northern Brazil
The Beck Depression Inventory (BDI) is a popular screening and research instrument for measuring severity of depression. The instrument was translated to Portuguese for use in Brazil in 1979; however, it was not until recently that its psychometric properties have been tested empirically for the Brazilian population. The purpose of the present study was to explore the BDI's psychometric properties in a northern region of Brazil and to test for possible relationships between certain demographic variables and BDI outcomes. Samples used in this study were from an urban area in Roraima, the northernmost state of Brazil. The BDI showed adequate levels of internal consistency in nonclinical and clinical samples. Female respondents had significantly higher scores than male respondents. Those who had lower levels of education, income, or occupational status had significantly higher scores than those with higher levels of these variables. Adolescents had significantly higher scores than adults from all age groups except those from age 19 to 22. No significant difference was found between those who identified themselves as “indigenous” and those who identified themselves as “non-indigenous.” Regression analysis results showed that the combination of gender, education, and age best accounted for the variance in BDI scores. An ANCOVA …

Athletic Trainers and Psychological Disorders Among Athletes: An Examination of Their Abilities to Recognize, Diagnose and Intervene.
Utilizing an analogue research design conducted via the Internet, this study assessed athletic trainers' abilities to recognize, diagnose, and intervene with a hypothetical athlete experiencing depression, and examined the impact of their gender, athlete gender, and athlete's presenting problem on their decisions. Athletic trainers' perceived competency in using psychosocial interventions with athletes, history of referring athletes to psychology professionals, and training backgrounds in psychology also were examined. Participants (270 male and 370 female certified athletic trainers) were randomly assigned to one of six conditions (Athlete Gender X Presenting Problem). After reading the appropriate vignette, they completed questions related to the athlete's psychological symptoms and diagnosis, referral recommendations, and use of psychosocial interventions if working with the athlete. The vignettes were identical except for the athlete's gender and problem. Overall, athletic trainers accurately identified the athlete's depressive symptoms/diagnosis and need for psychological referral. They rated the athlete significantly higher in Depressive Symptoms than in Anger/Agitation Symptoms and Compulsive Behavioral Symptoms, and as more likely to be experiencing a depressive disorder compared to an adjustment disorder, anxiety disorder, sleep disorder, or substance abuse disorder. Female athletic trainers provided significantly higher ratings of Depressive Symptoms than males and the injured athlete was rated …
