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.

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.

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 …

Masking Meaning
Chapter I describes the purpose of the project, which was to develop a body of work that exhibits my current thought process. The questions presented to myself consisted of the following: 1. How effective was the expression of my ideas socially and politically after the change to the work? 2. Was the minimal approach a tool that contributes or detracts from this effectiveness? 3. Did an increase in scale successfully act as an element of confrontation? Chapter II describes the inspiration behind the making of my work it also discusses problems encountered with an understanding of the viewer concerning imagery. Chapter III summarizes the methodology behind the execution of the new body of work. It also discusses how simplification of imagery works as a solution to my problems.

Comparisons of Improvement-Over-Chance Effect Sizes for Two Groups Under Variance Heterogeneity and Prior Probabilities
The distributional properties of improvement-over-chance, I, effect sizes derived from linear and quadratic predictive discriminant analysis (PDA) and from logistic regression analysis (LRA) for the two-group univariate classification were examined. Data were generated under varying levels of four data conditions: population separation, variance pattern, sample size, and prior probabilities. None of the indices provided acceptable estimates of effect for all the conditions examined. There were only a small number of conditions under which both accuracy and precision were acceptable. The results indicate that the decision of which method to choose is primarily determined by variance pattern and prior probabilities. Under variance homogeneity, any of the methods may be recommended. However, LRA is recommended when priors are equal or extreme and linear PDA is recommended when priors are moderate. Under variance heterogeneity, selecting a recommended method is more complex. In many cases, more than one method could be used appropriately.

Comparative Analysis of Management and Employee Job Satisfaction and Policy Perceptions.
The purpose of the study was to investigate the perceptions of job satisfaction as defined by management and nonmanagement employees and to compare both parties' perceptions of organizational benefits to a list prepared by the organization's benefit personnel. Turnover is costly to the organization, both in money and in the impact it has on those individuals remaining with the organization. Every effort should be undertaken to reduce the amount of turnover within the organization. A contributing factor leading to turnover may be a gap between what the employees believe is important to them and what management believes is important to the employees. The boundaries of the gap need to be identified before any effort can be made to reduce or bridge the gap. Once the boundaries are identified, policies can be analyzed and the possibility of reducing the gap investigated. Management as a whole must be aware of the needs and wants of their employees before any attempt to develop a retention strategy is undertaken. This knowledge can be acquired only through two-way communication with the employee. The communication process includes the simple process of asking employees for this information and then listening to how they respond. This study suggests …

Content-Based Image Retrieval by Integration of Metadata Encoded Multimedia Features in Constructing a Video Summarizer Application.
Content-based image retrieval (CBIR) is the retrieval of images from a collection by means of internal feature measures of the information content of the images. In CBIR systems, text media is usually used only to retrieve exemplar images for further searching by image feature content. This research work describes a new method for integrating multimedia text and image content features to increase the retrieval performance of the system. I am exploring the content-based features of an image extracted from a video to build a storyboard for search retrieval of images. Metadata encoded multimedia features include extracting primitive features like color, shape and text from an image. Histograms are built for all the features extracted and stored in a database. Images are searched based on comparing these histogram values of the extracted image with the stored values. These histogram values are used for extraction of keyframes from a collection of images parsed from a video file. Individual shots of images are extracted from a video clip and run through processes that extract the features and build the histogram values. A keyframe extraction algorithm is run to get the keyframes from the collection of images to build a storyboard of images. In …

Resource Efficient and Scalable Routing using Intelligent Mobile Agents
Many of the contemporary routing algorithms use simple mechanisms such as flooding or broadcasting to disseminate the routing information available to them. Such routing algorithms cause significant network resource overhead due to the large number of messages generated at each host/router throughout the route update process. Many of these messages are wasteful since they do not contribute to the route discovery process. Reducing the resource overhead may allow for several algorithms to be deployed in a wide range of networks (wireless and ad-hoc) which require a simple routing protocol due to limited availability of resources (memory and bandwidth). Motivated by the need to reduce the resource overhead associated with routing algorithms a new implementation of distance vector routing algorithm using an agent-based paradigm known as Agent-based Distance Vector Routing (ADVR) has been proposed. In ADVR, the ability of route discovery and message passing shifts from the nodes to individual agents that traverse the network, co-ordinate with each other and successively update the routing tables of the nodes they visit.

The Effects of Biofeedback and Verbal Feedback on the Training and Maintenance of Diaphragmatic Breathing
The purpose of this study was to evaluate the effects of a computer program on the training and maintenance of diaphragmatic breathing. The biofeedback portion was visual computer training and the results were displayed concurrently with participants' breathing responses to monitor display. The verbal feedback portion was praise that was given and recorded when participants responded with predominantly diaphragmatic breathing at the scheduled moment and response instruction that was given when participants responded with predominantly thoracic breathing. The results of this study indicate the computer program's effectiveness needs to be increased by supplementation with verbal feedback.

Dimensional Assessment of Empowerment in Organizations
This research project was inspired by a survey that was designed to help an organization determine how well it was doing in its efforts to empower associates and achieve a goal of continuous improvement. Initial review of the survey created suspicion that the survey was not built around the appropriate dimensions to accurately measure the level of empowerment in organizations. As such, the survey was psychometrically analyzed to determine the validity of the instrument as a measure of empowerment. Additionally, an extensive review of the literature was performed to determine new dimensions that would most accurately measure empowerment. Eight dimensions (culture, trust, accountability, leadership, ability, commitment, responsibility, and communication) were put forth as the most appropriate to measure empowerment. Subject matter experts with knowledge and experience in the area of organizational empowerment reviewed the new dimensions for accuracy and fit with the original survey items.

Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.
Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted …

Visual Cueing: Investigating the Effects of Text Annotation on Student Retention Rates
This Study examines the grades of students using study skill methods and those who do not. The experiment consists of giving the treatment group the opportunity to use well- known study techniques. The Control group could only read the material. Both groups were given ten minutes to read a pre-selected text. The text consisted of an 1,807 word lesson on the, "Technical Training Management System." Each group was given five minutes to take a twenty item quiz. Fifty-five students in the control group were limited to only reading the material. Fifty-six students in the treatment group could choose between highlighting, note-taking, and underlining. The results of the test scores were compared using a t - test for dependent samples. One week later, the same students in each group were re-tested, using the same quiz they had taken earlier. Students had five minutes to review study material. Study material for the treatment group included the same material they had annotated earlier. The Results from each group wascompared. Efforts were made to avoid potential flaws in previous studies, thereby producing more viable results. Results of this study indicate there is no significant difference between the grades of students who use the aforementioned …

Latin Mass for Choir, Orchestra, Soprano and Mezzo-Soprano Soloists
The Latin Mass is a musical composition in five movements, scored for large choir, standard orchestra, and two soloists. The movements are the standard parts of the Roman Catholic Mass Ordinary. The language is set mainly in Latin with two exceptions: the Kyrie movement is set in Greek (which is the standard Roman Catholic setting), and the Credo is simultaneously recited in English and sung in Latin. The work is scored using conventional notation techniques and employs rather conservative technical demands on both the choir and orchestra. No extended techniques are required of any of the performers. It is set in a modal harmonic language.

The Dynamic Foundation of Fractal Operators.
The fractal operators discussed in this dissertation are introduced in the form originally proposed in an earlier book of the candidate, which proves to be very convenient for physicists, due to its heuristic and intuitive nature. This dissertation proves that these fractal operators are the most convenient tools to address a number of problems in condensed matter, in accordance with the point of view of many other authors, and with the earlier book of the candidate. The microscopic foundation of the fractal calculus on the basis of either classical or quantum mechanics is still unknown, and the second part of this dissertation aims at this important task. This dissertation proves that the adoption of a master equation approach, and so of probabilistic as well as dynamical argument yields a satisfactory solution of the problem, as shown in a work by the candidate already published. At the same time, this dissertation shows that the foundation of Levy statistics is compatible with ordinary statistical mechanics and thermodynamics. The problem of the connection with the Kolmogorov-Sinai entropy is a delicate problem that, however, can be successfully solved. The derivation from a microscopic Liouville-like approach based on densities, however, is shown to be impossible. …

The Effects of Practice Procedure and Task Difficulty on Tonal Pattern Accuracy.
The study investigated the relative effectiveness of different proportions of time spent on physical and mental practice, in the context of a music performance of a tonal pattern over harmonic progressions of two difficulty levels. Using a sampling without replacement procedure, sixty undergraduate students were assigned to four practice groups partially blocked for musical instrument. The groups included a physical practice group, a mental practice group and two combined mental and physical practice groups in the proportions of (a) 66% physical and 33% mental, and (b) 33% physical and 66% mental. Each subject performed a pretest, a 3 minute practice session, and a posttest on both harmonic progressions. Presentation of the harmonic progressions were counterbalanced to control for practice effects All pre- and posttests were recorded and scored according to number of note errors. An ANCOVA procedure using pretest scores as covariates revealed that: (a) there were no differences between the different practice groups on the measure of note errors, (b) there was a significant difference between the two harmonic progressions on the measure of note errors, such that performance on the easy progression was significantly better than performance on the hard progression, and (c) there was a significant interaction …

The predictive influence of variables in three different academic learning environments on the intentions of music education majors to leave the degree program.
Attrition rates among students in music teacher training programs have contributed to a shortage of qualified music teachers for the nation's schools. The purpose of this study was to investigate the predictive relationship of academic variables in three different learning environments and the intent of a select population of music education majors to leave the degree program. The study drew upon the work of Tinto, Bean and Astin to form a theoretical foundation for examining variables unique to student withdrawal from the music education degree plan. Variables were examined within the context of three different learning environments: (1) applied lessons, (2) ensembles and (3) non-performance courses. Participants were 95 freshmen and sophomore music education majors at a public university who were enrolled in the music education degree program during the spring semester, 2002. Data included participant responses on the Music Student Inventory (MSI), a questionnaire developed specifically for the study, and grade data from university records. Independent variables in the study included participants' perceptions of (1) Ensemble experiences, (2) Applied lesson experiences, (3) Non-performance music course experiences, (3) Course requirements, and (4) Performance growth. Additional variables included: (1) Ensemble placement, (2) Course grades for music theory, applied lessons and aural …

Synthesis and host-guest interaction of cage-annulated podands, crown ethers, cryptands, cavitands and non-cage-annulated cryptands.
Symmetrical cage-annulated podands were synthesized via highly efficient synthetic strategies. Mechanisms to account for the key reaction steps in the syntheses are proposed; the proposed mechanisms receive support from the intermediates that have been isolated and characterized. An unusual complexation-promoted elimination reaction was studied, and a mechanism is proposed to account for the course of this reaction. This unusual elimination may generalized to other rigid systems and thus may extend our understanding of the role played by the host molecules in "cation-capture, anion-activation" via complexation with guest molecules. Thus, host-guest interaction serves not only to activate the anion but also may activate the leaving groups that participate in the complexation. Complexation-promoted elimination provides a convenient method to desymmetrize the cage while avoiding protection/deprotection steps. In addition, it offers a convenient method to prepare a chiral cage spacer by introducing 10 chiral centers into the host system in a single synthetic step. Cage-annulated monocyclic hosts that contain a cage-butylenoxy spacer were synthesized. Comparison of their metal ion complexation behavior as revealed by the results of electrospray ionization mass spectrometry (ESI-MS), alkali metal picrate extraction, and pseudohydroxide extraction with those displayed by the corresponding hosts that contain cage-ethylenoxy or cage-propylenoxy spacers reveals …

The Effects of Monitoring and Incompatible Contingencies on Say/Do Correspondence.
This study investigated effects of monitoring on correspondence between nonverbal responding and verbal descriptions of those contingencies, when verbal descriptions and contingencies were compatible and when incompatible. In the Nonverbal Component, the contingency for key pressing was either on a 0.8 s IRT or a 3.4 s IRT. In the Verbal Component, subjects made responses to a statement about the contingency for reinforcement in the Nonverbal Component. Shaping was used to establish targets of 0.8 s and 3.4 s in this component. Results indicated that across 7/8 opportunities subjects exhibited nonverbal and verbal behavior that was sensitive to their respective contingencies regardless of compatibility. This sensitivity to contingencies was not affected by the presence of a monitor.

A Comparison of Skill Level of Parents Trained in the Landreth Filial Therapy Model and Graduate Students Trained in Play Therapy
The purpose of this study was to determine if parents trained in the Landreth Filial Therapy Model could demonstrate child-centered play therapy skills as effectively as graduate play therapy students who completed an Introduction to Play Therapy course. The participants in both the parent group and the graduate student group were videotaped in play sessions with children pre- and post-training in order to measure change in adult empathic behavior as defined on the Measurement of Empathy in Adult-Child Interaction (MEACI). The specific skills measured in this study were (a) communicating acceptance to the child, (b) allowing the child to direct his or her own play during the play sessions, (c) demonstrating appropriate levels of involvement in the child's play, and (d) demonstrating empathic behavior toward the child. The Landreth Filial Therapy Model is a training system that utilizes both didactic and dynamic means to train parents and other paraprofessionals to be therapeutic agents of change with children. Parents are taught child-centered play therapy skills to use in weekly home play sessions with their children in order to strengthen the emotional bond between parent and child. The Introduction to Play Therapy course is a graduate-level counseling course at the University of …

Industrial Landscapes: Humanity Coexisting with Nature
The focus of this project was on creating images of our industrial landscape and shows the coexistence of culture and nature. I confronted the landscape from a position that is accepting of our present landscape. While not idealizing the present industrial landscape I wanted to depict it in a way that is not devoid of beauty. I believe that no matter how the land is altered a certain grace still comes through in any landscape. In not idealizing or criticizing I wanted to show industrial areas in an accepting light and reveal the grace and beauty that is within every landscape. It is through my photographs and all the subjective decisions made when creating these images that make it possible for others to see the beauty in these industrial landscapes.
