An Analytical Study of Robert Muczynski's Second Piano Trio
The purpose of this study is to provide scholastic research on Robert Muczynski's Second Piano Trio (1975) by presenting his biographical background, discussing influences and his musical style, and analyzing the work. Robert Muczynski (b.1929), a composer-pianist of Polish descent, studied with Alexander Tcherepnin (1899-1977). From traditional forms and techniques, he fashioned his own unique and innovative compositional style. The second piano trio, in particular, was deeper and more complex in its conception and affect than previous compositions. The first movement Andante molto opening leads to an allegro section, and the somber second movement builds to a heavy climax. The third movement is highly rhythmic and dramatically driven. Chapter I outlines the purpose of the study and the composer's biography. Chapter II describes Muczynski's compositional influences and the evolution of his musical language. Emphasis in this respect will be placed on the pedagogical role of Alexander Therepnin, as well as the important connections between Prokofiev, Tcherepnin and Muczynski. An exploration of other elements that have informed Muczynski's style is offered. Chapter III details the circumstances, general characteristics, and compositional technique of the Second Piano Trio. Detailed analysis of all three movements will be provided, with particular attention paid to aspects …

Reported Impact of a Correctional Facility's Presence on Community Solidarity: Huntsville, Texas
The problem examined is community solidarity in a well-established prison town. The primary question addressed in this study is "what is the reported impact of a correctional facility's presence on community solidarity?" This study is concerned with the community's perception about the problems, as well as the benefits involved in the housing of a prison and in particular the solidarity of the community. The relevant literature dates from 1929 to 2004 and examines a wide range of concepts associated with community studies and prison studies. Based on themes found in the review of prison literature; work issues, safety, concern about children, stress, community image, benefits, community identity, and community cohesion, seven research questions were constructed. A semi-structured interview was conducted of 81 residents of Walker County in Huntsville, Texas. Huntsville houses 9 prisons. The prison system is the primary employer in the county. A qualitative data analysis using Altius/tr as a tool for content analysis was used. Throughout the data, community residents consistently indicated solidarity. Emerging from the data were seven themes associated with community solidarity:(a) unqualified community pride, (b) normalization, (c) defensiveness against the media, (d) qualified community pride, (e) denial, (f) community and myths, (g) economics.

A Comparison of the Self-Efficacy Scores of Preservice Teachers Based on Initial College Experience
The purpose of this study was to determine if any statistically significant difference exists between the self-efficacy scores of student teachers who began their college experience at the community college level and student teachers who began their education at the university level. The study was used to determine whether or not the type of initial college experience impacted the first two years of college study, in relation to the development of a sense of self-efficacy at the end of the program of study. Self-efficacy data were gathered from beginning student teachers at two comparative institutions. The participants were enrolled in the colleges of education at two large metropolitan universities. One university was located in southern Texas and the other was located in north central Texas. The Teachers' Sense of Efficacy Scale was the instrument used, as well as a researcher-made questionnaire that collected demographic data. In addition to pattern of education, other independent variables included age, gender, ethnicity, certification level sought by the participant, and the number of contact hours spent by the participant in early field experiences in K-12 classrooms. A multiple regression analysis indicated no statistically significant difference in the composite score of the Teachers' Sense of Efficacy …

An unjust legacy: A critical study of the political campaigns of William Andrews Clark, 1888-1901.
In a time of laissez-faire government, monopolistic businesses and political debauchery, William Andrews Clark played a significant role in the developing West, achieving financial success rivaling Jay Gould, George Hearst, Andrew Carnegie, and J. P. Morgan. Clark built railroads, ranches, factories, utilities, and developed timber and water resources, and was internationally known as a capitalist, philanthropist and art collector. Nonetheless, Clark is unjustly remembered for his bitter twelve-year political battle with copper baron Marcus Daly that culminated in a scandalous senatorial election in January 1899. The subsequent investigation was a judicial travesty based on personal hatred and illicit tactics. Clark's political career had national implications and lasting consequences. His enemies shaped his legacy, and for one hundred years historians have unquestioningly accepted it.

Effects of Cautioning and Education in the Detection of Malingered Mild Traumatic Brain Injury
This study examined the effectiveness of cautioning and education on simulating a mild traumatic brain injury on several neuropsychological measures. The measures used included the Word Memory Test (WMT), Wechsler Adult Intelligence Scales® - Third Edition (WAIS®-III), Wechsler Memory Scales®-3rd Edition instrument (WMS®-III), 16-item version of the Rey Memory Test, and a self-report symptom checklist. Five experimental groups were used including clinical and non-clinical controls, as well as three simulation groups. The design and implementation of this study also attempted to correct several methodological short comings of prior research by increasing the incentives for participants, expanding the generalizability of findings and examining research compliance and participant self-perception through debriefing. Discriminant analysis was utilized to determine if specific functions existed that would correctly classify and distinguish each experimental group. Several discriminant functions had at least moderate canonical correlations and good classification accuracy. Results also include utility estimates given projected varying base rates of malingering.

Ion-Induced Damage In Si: A Fundamental Study of Basic Mechanisms over a Wide Range of Implantation Conditions
A new understanding of the damage formation mechanisms in Si is developed and investigated over an extended range of ion energy, dose, and irradiation temperature. A simple model for dealing with ion-induced damage is proposed, which is shown to be applicable over the range of implantation conditions. In particular the concept of defect "excesses" will be discussed. An excess exists in the lattice when there is a local surplus of one particular type of defect, such as an interstitial, over its complimentary defect (i.e., a vacancy). Mechanisms for producing such excesses by implantation will be discussed. The basis of this model specifies that accumulation of stable lattice damage during implantation depends upon the excess defects and not the total number of defects. The excess defect model is validated by fundamental damage studies involving ion implantation over a range of conditions. Confirmation of the model is provided by comparing damage profiles after implantation with computer simulation results. It will be shown that transport of ions in matter (TRIM) can be used effectively to model the ion-induced damage profile, i.e. excess defect distributions, by a simple subtraction process in which the spatially correlated defects are removed, thereby simulating recombination. Classic defect studies …

A Quantitative Study of Revenue and Expenditures at U.S. Community Colleges, 1980-2001
This study provides a detailed description of revenue and expenditure patterns of the United States community college by state and by institutional type (rural-, suburban-serving, and urban-serving) for each five-year period from 1980-81 to 2000-01. The Katsinas, Lacey, and Hardy classification schema for community colleges is used to analyze data from the National Center for Education Statistics' Integrated Postsecondary Educational Data System (IPEDS) and Higher Education General Information Surveys (HEGIS). Further analysis clusters states into the following groupings: states with/without substantial local funding, large "mega-states" versus all other states (employing the methodology developed by Grapevine at Illinois State University), and the structure of state coordination (as developed by Tollefson and others in their studies of state community college systems). The analysis showed wide differences in the various funding patterns for community colleges as related to revenue streams. As late as 1980-91, 16 states contributed 60% or more of the total budgets for their community colleges; by 2000-01, no state did so. By college type, rural-serving community colleges saw the greatest net negative change in their operating budget margins, from 3.2% to 0.4%, although it should be noted that every one of the community college types also experienced a significant decline …

Relationships between selected sociometric variables and academic performance for counselors in training.
The purpose of this research was to examine what relationships existed between selected sociometric variables and measures of academic performance for students in a counselor training program. The sociometric variables included counseling ability, counseling knowledge, and friendship. Academic performance measures included subject GPAs, group counseling participation and final grades, prepracticum grades, and practicum grades. Data was collected from sociometric questionnaires and academic records from the years 1991 to 2004, for 840 subjects who participated in a group counseling class at the University of North Texas. Counseling knowledge had the highest correlations with all academic measures except group counseling final grades, in which counseling ability had the highest strength. The strongest correlations for all three sociometric variables occurred with group counseling final grades; correlations were r = 0.42 for counseling ability, r = 0.40 for counseling knowledge, and r = 0.30 for friendship. The sociometric variable of friendship had the lowest correlations in all academic measures, but was more significant than expected. The friendship sociometric variable may account for likeability as a factor in making sociometric choices. Combined sociometric scores led to increased correlation strength and explained variances that reached the large level of 30% with group counseling final grades. A …

Opening the Door to Meaning-Making in Secondary Art History Instruction
Each day countless numbers of high school students remain standing at the threshold of the door to meaningful learning in art history because of traditional authoritative instructional methods and content. With the keys of feminist pedagogy, interactive teaching methods, and the new art histories, the teacher can now unlock that door and lead students to personally relevant learning on the other side. A case study using both qualitative and quantitative research methods was conducted in a secondary art history classroom to examine the teacher's pedagogical choices and the degree to which they enable meaningful and relevant student learning. The analysis of multiple sources of data, including classroom observations, revealed statistically significant correlations between the teacher's instructional methods and the content, as well as their impact on student meaning-making.

Personal Passions and Carthusian Influences Evident in Rogier Van Der Weyden's Crucified Christ between the Virgin and Saint John and Diptych of the Crucifixion
This thesis examines Rogier Van Der Weyden's two unique fifteenth century Crucifixions, The Crucified Christ Between the Virgin and Saint John and The Diptych of the Crucifixion, in light of Carthusian beliefs, practices and relevant devotional texts. The specific text used to support this examination is the Vita Christi by Ludolph of Saxony, which in part deals specifically with the Hours of the Passion. Ludolph's text is given visual form in Rogier's paintings and supports the assertion that Rogier and Ludolph were connected by a shared belief and worldview. Key aspects of Rogier's life, supported by original documentation- familial ties, associates, patrons, use of finances, and his close involvement with the Carthusians-- support this assertion. Other models of connections of belief, evidenced through artist's work, are corroborated in the work of Grunewald, Sluter and Durer.

MBE Growth and Instrumentation
This thesis mainly aims at application of principles of engineering technology in the field of molecular beam epitaxy (MBE). MBE is a versatile technique for growing epitaxial thin films of semiconductors and metals by impinging molecular beams of atoms onto a heated substrate under ultra-high vacuum (UHV) conditions. Here, a LabVIEW® (laboratory virtual instrument engineering workbench) software (National Instruments Corp., http://www.ni.com/legal/termsofuse/unitedstates/usH) program is developed that would form the basis of a real-time control system that would transform MBE into a true-production technology. Growth conditions can be monitored in real-time with the help of reflection high energy electron diffraction (RHEED) technique. The period of one RHEED oscillation corresponds exactly to the growth of one monolayer of atoms of the semiconductor material. The PCI-1409 frame grabber card supplied by National Instruments is used in conjunction with the LabVIEW software to capture the RHEED images and capture the intensity of RHEED oscillations. The intensity values are written to a text file and plotted in the form of a graph. A fast Fourier transform of these oscillations gives the growth rate of the epi-wafer being grown. All the data being captured by the LabVIEW program can be saved to file forming a growth pedigree …

Propagation analysis of a 900 MHz spread spectrum centralized traffic signal control system.
The objective of this research is to investigate different propagation models to determine if specified models accurately predict received signal levels for short path 900 MHz spread spectrum radio systems. The City of Denton, Texas provided data and physical facilities used in the course of this study. The literature review indicates that propagation models have not been studied specifically for short path spread spectrum radio systems. This work should provide guidelines and be a useful example for planning and implementing such radio systems. The propagation model involves the following considerations: analysis of intervening terrain, path length, and fixed system gains and losses.

Effect of Biofeedback-Assisted Relaxation Therapy on the Psychophysiological Measures of Stressed-Out Working Professional Mothers
This study was designed to determine the effectiveness of biofeedback-assisted relaxation therapy on reducing psychophysiological stress levels of working professional mothers. Participants were 14 working professional mothers from a major daily newspaper. Reported stress levels were measured with the 123 question Stress Profile (Nowack, 1990) three times during the eight week treatment study that was held at the women's workplace. A repeated measure ANOVA design was used to analyze the data and a partial eta squared was used to calculate effect size. As hypothesized, the study found a statistically significant reduction of reported stress levels (F=8.62; p=.001) and a statistically significant (F=3.65; p=.01) reduction in measured muscle tension across subjects. Practical significance (effect size) was found for reduction in reported stress levels (n=.39) and reduction in muscle tension (n=.21).

Technical Communication and the Needs of Small 501(c)(3) Organizations
This exploratory study examines documentation practices and processes in ten small non-profit organizations. The objectives of this study were to answer the following two research questions: (1) What organizational needs do small non-profit organizations have that are relevant to technical communication? and (2) How are small 501(c)(3) organizations attempting to meet these needs? Which of these attempted solutions are ineffective? Semi-structured interviews were conducted with two people from each organization: the executive director and a volunteer. Interviews were transcribed and analyzed, and grounded theory was used to identify coding categories related to documentation development. Primary findings suggest that interviewees are aware that they need documentation, yet they often postpone developing such documentation until problems develop. The study findings also suggest that interviewees across different nonprofit organizations value documentation for similar reasons. Strategies are provided for technical communicators interested in working with nonprofit organizations, and additional research avenues are identified.

Synthesis and Characterization of 2,3-Dichloropyrrolo[1,2-a]benzimidazol-1-one and Its Methylthiol Derivatives
Condensation of 2,3-dichloromaleic anhydride and o-phenylenediamine in refluxing toluene affords the three compounds 2,3-dichloro-N-o-C6H4(NH2)maleimide (1), N,N¢-o-C6H4-bis(2,3-dichloromaleimide) (2), and 2,3-dichloropyrrolo[1,2-a]benzimidazol-1-one (3), with compound 1 as the major product. Repeating the same reaction in the presence of added PTSA furnishes compound 3 as the major product. Treatment of 3 with methylthiol in the presence of pyridine affords monosulfide compounds 2-chloro-3-methylthiopyrrolo[1,2-a]benzimidazol-1-one (4) and and the disulfide derivatives 2,3-di(methylthio)pyrrolo[1,2-a]benzimidazol-1-one (5). The substitution of the first chlorine group in compound 3 occurs regioselectively at C-3 to produce compound 4, followed by replacement of the remaining chlorine group to furnish the disulfide compounds 5. The new compounds 1-5 have been isolated by column chromatography and characterized by IR, NMR, XRD, CV and etc.

Mathematical Modeling of Charged Liquid Droplets: Numerical Simulation and Stability Analysis
The goal of this thesis is to study of the evolution of 3D electrically charged liquid droplets of fluid evolving under the influence of surface tension and electrostatic forces. In the first part of the thesis, an appropriate mathematical model of the problem is introduced and the linear stability analysis is developed by perturbing a sphere with spherical harmonics. In the second part, the numerical solution of the problem is described with the use of the boundary elements method (BEM) on an adaptive mesh of triangular elements. The numerical method is validated by comparison with exact solutions. Finally, various numerical results are presented. These include neck formation in droplets, the evolution of surfaces with holes, singularity formation on droplets with various symmetries and numerical evidence that oblate spheroids are unstable.

Improving Recall of Browsing Sets in Image Retrieval from a Semiotics Perspective
The purpose of dissertation is to utilize connotative messages for enhancing image retrieval and browsing. By adopting semiotics as a theoretical tool, this study explores problems of image retrieval and proposes an image retrieval model. The semiotics approach conceptually demonstrates that: 1) a fundamental reason for the dissonance between retrieved images and user needs is representation of connotative messages, and 2) the image retrieval model which makes use of denotative index terms is able to facilitate users to browse connotatively related images effectively even when the users' needs are potentially expressed in the form of denotative query. Two experiments are performed for verifying the semiotic-based image retrieval model and evaluating the effectiveness of the model. As data sources, 5,199 records are collected from Artefacts Canada: Humanities by Canadian Heritage Information Network, and the candidate terms of connotation and denotation are extracted from Art & Architecture Thesaurus. The first experiment, by applying term association measures, verifies that the connotative messages of an image can be derived from denotative messages of the image. The second experiment reveals that the association thesaurus which is constructed based on the associations between connotation and denotation facilitates assigning connotative terms to image documents. In addition, the …

A Rhetorical Guide to Ebb
In the essay A Rhetorical Guide to Ebb I explore the diverse array of influences in art, and music that guided the creation of the composition Ebb, for 13 musicians and electronics. Of those influences, the boxes of the American artist Joseph Cornell played a particularly important role. Having based the conceptual framework for Ebb on ideas taken from Cornell, the essay, instead of being driven by a single thesis, involves the creation of conceptual boxes. These conceptual boxes emphasize the influence of the artist Joseph Cornell, along with the composers Iannis Xenakis and Gérard Grisey. In addition, a time line documenting the stages in Ebb's creation is included.

A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.
Access:
Use of this item is restricted to the UNT Community
The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences between the proximal and distal portions of the DA with regard to lumen occlusion, endothelial cells, smooth muscle and elastin. Endothelial cell proliferation begins to occur as early as external pipping, with the lumen almost completely occluded by the 3rd day of post-hatching life. Expression of vascular endothelial growth factor (VEGF) increases in avian endothelial cells during hatching. I provide a morphological timeline of changes in the DA as the chicken develops from embryo to hatchling.

Democratic Pantheism in the Political Theory of Alexis de Tocqueville
Access:
Use of this item is restricted to the UNT Community
According to Alexis de Tocqueville, humanity is entering a new age of political and social equality, a new epoch in which the human race has no historical example or experience. As a result, he holds humanity's future will be largely determined by the political and moral choices made in this transitional time. For Tocqueville, the new egalitarian era is a forgone conclusion, but for him, the pressing question is whether humanity will choose a future in which it enchains itself to new forms of tyranny, or, whether the human race can establish the political and moral institutions designed to assure human freedom and dignity. In Tocqueville's view, liberty or slavery are the two choices modern men and women have in front of them, and it is the intent of this dissertation to explore Tocqueville's warning in regard to the latter choice. Tocqueville warns us that modern democratic peoples must beware of the moral and political effects of a new type of political philosophy, a political theory he terms democratic pantheism. Democratic pantheism is a philosophic doctrine that treats egalitarianism as a "religion" in which all social and political striving is directed toward realizing a providentially ordained strict equality of conditions. …

Generic Algebras and Kazhdan-Lusztig Theory for Monomial Groups
Access:
Use of this item is restricted to the UNT Community
The Iwahori-Hecke algebras of Coxeter groups play a central role in the study of representations of semisimple Lie-type groups. An important tool is the combinatorial approach to representations of Iwahori-Hecke algebras introduced by Kazhdan and Lusztig in 1979. In this dissertation, I discuss a generalization of the Iwahori-Hecke algebra of the symmetric group that is instead based on the complex reflection group G(r,1,n). Using the analogues of Kazhdan and Lusztig's R-polynomials, I show that this algebra determines a partial order on G(r,1,n) that generalizes the Chevalley-Bruhat order on the symmetric group. I also consider possible analogues of Kazhdan-Lusztig polynomials.

Using Reinforcement Learning in Partial Order Plan Space
Access:
Use of this item is restricted to the UNT Community
Partial order planning is an important approach that solves planning problems without completely specifying the orderings between the actions in the plan. This property provides greater flexibility in executing plans; hence making the partial order planners a preferred choice over other planning methodologies. However, in order to find partially ordered plans, partial order planners perform a search in plan space rather than in space of world states and an uninformed search in plan space leads to poor efficiency. In this thesis, I discuss applying a reinforcement learning method, called First-visit Monte Carlo method, to partial order planning in order to design agents which do not need any training data or heuristics but are still able to make informed decisions in plan space based on experience. Communicating effectively with the agent is crucial in reinforcement learning. I address how this task was accomplished in plan space and the results from an evaluation of a blocks world test bed.

I start writing by conjuring up an image in my mind. Sometimes it will be something that I have thought about for a while, sometimes it will be something that I sit around attempting to create. Either way, it is simply the idea that I need in order to get started. People will say, "Just sit down and write" which I can do, but it does not mean I will end up anywhere worthwhile. In my writing I need a focus. I need an idea or just one image to get me writing and I can base an entire story off of that one image. I think the reason this works for me is because in my mind it is an illustration and always something that is vibrant and unique. I want the image to stand out and to mean something because I feel that it comes to me for a specific reason, I just have to piece it all together and let the characters and plot unfold for themselves. People often say this, that the characters end up running the story. I think this is true, but in my case my stories are not so driven by character or …
