The purpose of this study is to identify what detail design tools are more productive for the different types of professional software developers. By establishing a match between the detail design tool and the cognitive style of the professional programmer, the end product (Information Systems) should be of a higher quality. Two laboratory experiments were conducted. The first experiment was with professional Software Developers; the second one was with students. The dependant variables considered in this study were the number of semantic errors and the time required to complete a design task for conditional logic. The independent variables were the cognitive style of the subject, the complexity of the task, and the detail design tools. Decision trees, flowcharts and pseudocode were used as detailed design tools. Field dependence was the only dimension of cognitive style that was tested.

The most important question addresed in this study was whether there is any difference in student learning between a motion group and a non-motion group. The interactive video courseware is currently a part of the curriculum in this district. It was used in its original form with the contrast group. For the experimental group one unit of the courseware was modified to remove the motion video and replace it with photorealistic graphics that served as the non-motion part of the study. Covariates were selected to compensate for any differences in the two groups. A pretest and posttest was administered to both groups. Analysis of the posttest scores indicated that there was no difference in learning if motion in the presentation was the only variable.

The Czechoslovakian composer Jindrich Feld (b.1925) composed Introduzione, Toccata e Fuga per Flauto Solo, for the Italian flutist Roberto Frabbriciani. Feld's Introduzione is from his third style period. This work may be labeled as a synthesis of the experiments and experiences that have enabled him to create his own mature style of expression.

The chemical fate and biological impacts of cyfluthrin in aquatic ecosystems were investigated using microcosms (1.9 m^3 concrete tanks) during 1989. Results were compared to a concurrent pesticide registration study using mesocosms (634.7 m^3 earthen ponds). Ten spray drift and five soil runoff simulations were conducted. Pesticide loadings were scaled by system volume, with the same experimental design in ponds and microcosms. Aqueous cyfluthrin concentrations and sediment residue values were generally higher in microcosms, while aqueous half-life was shorter in the smaller systems.

The primary purpose of this study was to determine if there is a relationship between the bibliographic citation practices of the members of a discipline and the emphasis placed on citation accuracy and purposes in the graduate instruction of the discipline.

This study traces the significant developments in the late nineteenth and early twentieth centuries which led to the development of electronic music and increased writing for percussion. Whether by coincidence or premeditation, the field of percussion in Western culture and electronic music share many parallel aspects in their history. Carlos Chavez, Edgard Varese and John Cage foresaw a time when electronic music would allow composers to realize compositions with ease, provide new sounds to the spectrum of possible material for pieces and aid in the conception of works. Significantly, these same composers were important figures in the development of percussion composition. In many ways, Lejaren Hiller's Machine Music can be seen as a culmination of the developments which had been taking place in the history of electronic music and percussion music. A product of the innovations in both fields, it poses some formidable problems for the performers. This study will give some background into its composition, examine its structure and deal with its performance problems.

The mitigation of outliers serves to increase the strength of a relationship between variables. This study defined outliers in three different ways and used five regression procedures to describe the effects of outliers on 50 data sets. This study also examined the relationship among the shape of the distribution, skewness, and outliers.

The purpose of this study was to investigate the interpersonal influences which Bohumil Makovsky, Director of Bands and Chairman of the Music Department at Oklahoma A&M College from 1915 to 1943, had on his students and peers, as confirmed through the perceptions of selected individuals, and to determine what personal characteristics and means he drew upon to induce changes in his students and peers.

This study examines the five late keyboard works of Cesar Franck: the Prelude, Chorale, and Fugue and the Prelude. Aria, and Finale for piano, and the three organ chorales. The study focuses on harmonic and contrapuntal techniques and their interrelationships, placing the discussion in the context of an analysis of the whole piece. The primary goal is to identify the salient characteristics of each piece; a secondary goal is to identify common harmonic and contrapuntal aspects of Franck's style.

The major purpose of this study was to determine if pre-clinical medical school course examinations reflect critical thinking skills. The entire second year class from a medical school in the southwest made up the population. Student examination results from the first two years as well as scores on the Watson-Glaser Critical Thinking Appraisal were used in this study.

This study identified and compared characteristics in the career progression of African-American college presidents of institutions in the continental United States. The study was concerned with personal, educational and professional characteristics of these senior level administrators. From a population of 141 individuals, 73 presidents participated in this study. Frequencies, means, percentages, chi-square, crosstabulations and analysis of variance (ANOVA) were employed in the analysis of data. The level of significance was set at 0.05.

This study examines the association between the attitudes of students toward computers and their knowledge of the ethical uses of computers. The focus for this research was undergraduate students in the Colleges of Arts and Sciences (Department of Computer Science), Business and Education at the University of North Texas in Denton, Texas.

L-shell x-ray production cross sections are presented for Fe, Ni, Cu, Zn, Ga, and Ge by 0.5- to 5.0-MeV protons and by 0.5- to 8.0-MeV helium ions and Ca, Fe, Ni, Cu, and Ge by 0.75- to 4.5-MeV lithium ions. These measurements are compared to the first Born theory and the perturbed-stationary- state theory with energy-loss, Coulomb deflection, and relativistic corrections (ECPSSR). The results are also compared to previous experimental investigations. The high precision x-ray measurements were performed with a windowless Si(Li) detector. The efficiency of the detector was determined by the use of thin target atomic-field bremsstrahlung produced by 66.5 keV electrons. The measured bremsstrahlung spectra were compared to theoretical bremsstrahlung distributions in order to obtain an efficiency versus energy curve. The targets for the measurement were manufactured by the vacuum evaporation of the target element onto thin foils of carbon. Impurities in the carbon caused interferences inthe L-shell x-ray peaks. Special cleansing procedures were developed that reduced the impurity concentrations in the carbon foil, making the use of less than 5 μg/cm^2 targets possible. The first Born theory is seen to greatly overpredict the data at low ion energies. The ECPSSR theory matches the data very well at …

The purposes of this study were to compare the childrearing attitudes of church-related Korean American immigrant parents and Korean parents as measured by the Parent As A Teacher Inventory (PAAT), and to identify relationships between the PAAT childrearing subsets and demographic variables including sex of child, sex of parent, education of parent, family income level, maternal employment, accessibility to the child, language of parent, and length of residence in America.

The problem addressed in this study was to determine if a significant association exists between attributions and academic achievement among students in a program of religious training at a Bible college. The research was designed to ascertain if optimistic attributions are more frequently associated with students in programs of religious education than with students in a public state-supported university environment. No significant correlation was found between optimistic explanatory styles and the academic achievement of Bible college students. A significant positive difference was found to exist between the explanatory styles of students at The Criswell College and students at the University of North Texas. Students in religious courses of study tended toward attributions for negative events that were external, unstable, and specific. The University of North Texas students tended toward attributions for negative events that were internal, stable, and global.

Male and female college students were administered scales assessing their daily hassles, negative life events, control, commitment, challenge, psychological symptomatology, psychological distress, and physical symptomatology. Stepwise multiple regression analyses showed that control, commitment, and challenge act in an additive (rather than multiplicative) manner in relation to psychological and physical outcome measures.

The focus of this study will be the impact of Neue Sachlichkeit on Zeitoper, specifically its influence upon Hindemith's operatic output. The purpose of this paper is not to.subject these works to detailed musical analysis, but rather to place Hindemith's Zeitopern in historical perspective, examining how they were influenced by and mirrored the aesthetic atmosphere of the Weimar Republic.

The theme of this study is that seven major East Asian less developed countries (LDCs) have experienced "dependent development," and that some internal and external intervening factors mattered in that process. Utilizing a framework of "dependent development," the data analysis deals with the political economy of development in these countries. This analysis supports the fundamental arguments of the dependent development perspective, which emphasize positive effects of foreign capital dependence in domestic capital formation and industrialization in East Asian LDCs. This perspective assumes the active role of the state, and it is found here to be crucial in capital accumulation and in economic growth. This cross-national time-series analysis also shows that the effects of external dependence and military spending on capital accumulation and economic growth can be considered as a regional phenomenon. The dependent development perspective offers a useful way to understand economic dynamism of East Asian LDCs for the past two decades.

The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning.

This dissertation contains the first complete Latin-English translation of one of the most controversial music theory treatises of the fifteenth-century: the Musica Practica (Bologna, 1942) of Bartolomeo Ramos de Pareia. its title as well as its content illustrate the Renaissance transformation from the abstract mathematical approach of "musica speculativa" to that of an emphasis upon the everyday demands of the practicing musician. Although Ramos provides traditional explanations of the modes, counterpoint, "musica ficta," and white mensural notation, his innovations in temperament, solmization, mutation, and the gamut set this treatise apart from other ffifteenth-century music treatises. Ramos's rejection of traditional Pythagorean-Boethian-Guidonian explanations, coupled with his strong polemic criticisms of the auctoritas, resulted in a treatise that remained at the center of heated debate well into the sixteenth century.

This study is an examination of the Surrealist movement and its influence on the piano music of twentieth century American composers. The first chapter explores the philosophies of the Surrealists as well as the characteristics found in Surrealist art and literature. The characteristics discussed include: 1) the practice of automatism; 2) the juxtaposition of unrelated themes or images; and 3) the creation of dream-like atmospheres.

The factors involved in calculating Standard Visual Range (SVR) are discussed, and a comparison is made between the visibility reported by airport observers and the photographic slide/ optical densitometer method of calculating SVR. Using slides of Houston, Texas, from the fall and winter of 1988-89, it was found that the altitude at which the contrast measurements are made significantly affects the SVR. Also an index for predicting high and low humidity was developed using the blue/red ratio of the log exposure of the sky, and sun/shade target condition.
