This study models the human process of music cognition on the digital computer. The definition of music cognition is derived from the work in music cognition done by the researchers Carol Krumhansl and Edward Kessler, and by Mari Jones, as well as from the music theories of Heinrich Schenker. The computer implementation functions in three stages. First, it translates a musical "performance" in the form of MIDI (Musical Instrument Digital Interface) messages into LISP structures. Second, the various parameters of the performance are examined separately a la Jones's joint accent structure, quantified according to psychological findings, and adjusted to a common scale. The findings of Krumhansl and Kessler are used to evaluate the consonance of each note with respect to the key of the piece and with respect to the immediately sounding harmony. This process yields a multidimensional set of points, each of which is a cognitive evaluation of a single musical event within the context of the piece of music within which it occurred. This set of points forms a metric space in multi-dimensional Euclidean space. The third phase of the analysis maps the set of points into a topology-preserving data structure for a Schenkerian-like middleground structural analysis. This …

The federal income tax system in the United States depends upon a high degree of voluntary compliance. The IRS estimates that the voluntary compliance level is declining and that this tax compliance gap cost the government an estimated $90.5 billion in 1981. Between 1979 and 1982, Congress made several changes in the tax laws designed to improve tax compliance. Extensive data was collected by the IRS for 1979 and 1982 through the random sample audits of approximately 50,000 taxpayers on the Taxpayer Compliance Measurement Program (TCMP), which is conducted every three years. During the period 1979 through 1982, Congress lowered the marginal tax rates, added some fairly severe penalties, for both taxpayers and paid return preparers, and increased information reporting requirements for certain types of income. In this research, it was hypothesized that voluntary compliance should increase in response to lower marginal rates, a higher risk of detection due to additional reporting requirements, and increased penalties. Multiple regression analysis was employed to test these hypotheses, using 1979 and 1982 TCMP data. Because of the requirements for taxpayer confidentiality, it was necessary for the IRS to run the data and provide the aggregate data results for the research. The results provided …

Nuclear magnetic resonance (NMR) provides a convenient probe for the study of molecular reorientation in liquids because nuclear spin-lattice relaxation times are dependent upon the details of molecular motion. The combined application of Raman and Infrared (IR) lineshape analysis can furnish more complete information to characterize the anisotropic rotation of molecules. Presented here are the studies of NMR relaxation times, together with Raman/IR Mneshape analysis of the solvent and temperature dependence of rotational diffusion in 1,3,5-tribromobenzene and 1,3,5-trifluorobenzene. In these experiments, it was found that the rotational diffusion constants calculated from Perrin's stick model were two to three times smaller than the measured values of D, and D,,. Similarly, rotational diffusion constants predicted by the Hu-Zwanzig slip model were too large by a factor of 2. Application of the newer Hynes-Kapral-Weinberg model furnished rotational diffusion constants that were in reasonable agreement with the experimental results. The vibrational peak frequencies and relaxation times of the isotropic Raman spectra of the υ1 modes of CD2Br2 and CHBr3 were studied in solution. The frequency shifts in non-interactive solvents were explained well on the basis of solution variations in the dispersion energy. In Lewis bases, the displacements were in some, but not all, cases …

This dissertation examines the effect that the introduction of an advanced manufacturing technology, specifically robotics, has on the work force of an aerospace defense company. In this endeavor, there are two main objectives. First, this study determines whether workers feel that their jobs are threatened by the introduction of robotic technology. Secondly, the research compares the degree to which workers from different labor types feel this threat. A review of the literature reveals that the technical factors involving manufacturing technology have been thoroughly examined and discussed, but the effect that they have on the work force has been somewhat neglected. This dissertation develops ten hypotheses to ascertain the perceived threat to job security for workers within an aerospace defense company. This study is based on an employee survey that examined the employee's perceived threat to job security by the introduction of robotics. The primary research was obtained from employees within an aerospace defense company through the use of questionnaires in a three phase approach. The first phase utilized a pretest that sampled the questionnaire prior to the company-wide solicitation. The second phase administered the questionnaire to the three labor types within the work force. Phase three consisted of data reduction …

The study investigated the relationship among three cognitive styles and summarization abilities. Both summarization products and processes were examined. Summarizing products were scored and a canonical correlation analysis was performed to determine their relationship with three cognitive styles. Summarizing processes were examined by videotaping students as they provided think aloud protocols. Their processes were recorded on composing style sheets and analyzed qualitatively. Subjects were sixth-grade students in self-contained classes in a suburban school district. Summarizing products were collected over a two week period in the fall. Summarizing processes were collected over an eight week period in the spring of the same school year. The results of the summarizing products analysis suggest that cognitive styles are related to summarization abilities. Two canonical correlations among the two variable sets were statistically significant at the .05 level of significance (.33 and .29). The results further suggest that students who are field independent, reflective, and flexible in their attentional style may be more adept at organizing their ideas and using written mechanics while summarizing. Students who are impulsive and constricted in attentional style may exhibit strength in expressing their ideas while summarizing. Results of the summarizing processes analysis suggest that students of one cognitive …

One of the most important compositional theories of Alexander Tcherepnin (1899-1977), Russian-American composer and pianist, is the Eurasian ideology, which was a result of the influence of Eastern culture. Inspired by this theory, Tcherepnin not only extricated himself from his own compositional techniques, but also intensified his search for musical folklore. In April, 1934, he began a world tour which was to include China, Japan, Singapore, the Philippines, Egypt, and Palestine, to search for "musical folklore." He became so fascinated with the culture of ancient China that he cancelled the rest of his arrangements, and, except for visits to Japan, he remained in China for three years, until the outbreak of the Sino-Japanese War in July, 1937. During his three-year stay in China, Tcherepnin was greatly attracted to Chinese culture, and as a result, Chinese culture influenced his music to a significant degree. This essay examines the manner in which Tcherepnin's music was influenced by his experiences in China. In order to precisely analyze the close affiliation between Chinese musical elements and Tcherepnin's "Chinese Mikrokosmos," many original Chinese sources proved indispensable in this study. These sources include Chinese folk music, theater music, instrumental music, religious music, and Chinese periodicals and …

The purpose of this study was to investigate the extent to which a non-verbal test of intelligence, the Test of Non-Verbal Intelligence (TONI), may be used for assessing intellectual abilities of children in India. This investigation is considered important since current instruments used in India were developed several years ago and do not adequately reflect present standards of performance. Further, current instruments do not demonstrate adequate validity, as procedures for development and cultural transport were frequently not in adherence to recommended guidelines for such practice. Data were collected from 91 normally achieving and 18 mentally retarded Indian children, currently enrolled in elementary schools. Data from an American comparison group were procured from the authors of the TONI. Subjects were matched on age, grade, and area of residence. Subjects were also from comparative socioeconomic backgrounds. Literature review of the theoretical framework supporting cross-cultural measurement of intellectual ability, a summary of major instruments developed for cross-cultural use, non-verbal measures of intellectual ability in India, and issues in cross-cultural research are discussed, with recommended methodology for test transport. Major findings are: (a) the factor scales derived from the Indian and American normally achieving groups indicate significant differences; (b) items 1, 3, 5, 8, …

This study compared three methods of selecting the best discriminating test items and the resultant test reliability of mastery/nonmastery classifications. These three methods were (a) the agreement approach, (b) the phi coefficient approach, and (c) the random selection approach. Test responses from 1,836 students on a 50-item physical science test were used, from which 90 distinct data sets were generated for analysis. These 90 data sets contained 10 replications of the combination of three different sample sizes (75, 150, and 300) and three different numbers of test items (15, 25, and 35). The results of this study indicated that the agreement approach was an appropriate method to be used for selecting criterion-referenced test items at the classroom level, while the phi coefficient approach was an appropriate method to be used at the district and/or state levels. The random selection method did not have similar characteristics in selecting test items and produced the lowest reliabilities, when compared with the agreement and the phi coefficient approaches.

This study provides a rationale for advising students on whether to enroll in individualized/self-paced computer courses. It identifies seven factors that have a significant correlation with success in an individualized computer course. The sample comprises all the students enrolled in individualized computer courses at Lee College, Baytown, Texas in the spring semester of 1988. Students completed a survey to determine whether they had previous computer experiences, whether they operated with a level of introvert personality characteristics, and whether the individualized computer course was their first choice. Students completed a learning style inventory and a score was determined using the items relating to individualized computer studies. Data collected in the Lee College records office included high school percentile rank, standardized reading score, standardized mathematics score, college hours completed, course withdrawals, and age. The following seven factors were shown by the data to have a significant correlation with a final grade (in order of decreasing significance): (a) learning style inventory, (b) high school percentile, (c) standardized mathematics score, (d) standardized reading score, (e) previous computer experience, (f) number of college hours, and (g) age. The following three factors were shown by the data to have no significant correlation with a final grade: …

Autistic adolescents need direct, systematic training of social skills since major difficulties in communication, lack of empathy, and various changes during adolescence present major roadblocks to the acquisition of normal peer relationships and increasing independence. A case study approach was utilized to examine treatment effects of a social skills training program implemented with four autistic adolescent boys in a naturalistic setting. Findings based on objective measures and subjective reports indicated that each subject made gains in targeted social skills over the course of treatment. Treatment strategies such as modeling, coaching, roleplaying, one to one instruction, and in vivo procedures were found to be effective teaching techniques. Major benefits and limitations of the study were discussed.

This thesis attempts to analyze the market response of stock prices of major U.S. banks to the February, 1987 Brazilian loan default announcement. The study's general hypothesis is that the market revalued stock prices according to each bank's amount of Brazilian loan exposure. The first chapter examines the significance of the default announcement. A survey of related literature is presented in the second chapter. Chapter III specifies the methodological techniques involved in analysis of the data. Chapter IV reports the findings of the study. Conclusions about the results are drawn in Chapter V. The results indicate the market is efficient. They also suggest that individual exposure was the major determinant of bank stock price decline.

This study predicted that individuals diagnosed as having higher levels of stress, based upon DSM-III-R, Axis IV ratings, would also be diagnosed as having more severe forms of mental illness. Conversely, it predicted that individuals with higher premorbid health ratings, according to DSM-III-R, Axis V, would be diagnosed as having less severe forms of mental illness. Highly significant correlations were found between stress ratings and severity of disorder. Significant inverse relationships were also found between Axis V ratings and disorder severity. Additionally, several other demographic variables were significantly correlated with severity of disorder.

Social skills training is a need among autistic adolescents. This investigation examined a social skills training program involving several teaching strategies. Specific social skills were targeted for improvement. Attempts to decrease negative social behaviors were made. Five autistic adolescents participated in the program and five were selected for the no-treatment group. Two measures were used. A survey addressing the skills targeted in the program was completed by parents and teachers before and after the program. A test conversation with a stranger and a peer was conducted with each subject before and after the program. Anecdotal information was obtained from therapists, teachers, and parents. Results provided information on the effectiveness of this social skills program. The benefits and limitations of the program were discussed.

The evolution of the People's Republic of China's Latin American policy from Mao to Deng consists of four stages: (1) communist internationalism, (2) revolutionary policy, (3) government contacts and peaceful co-existence, and (4) independent and open policy. Besides explaining the meaning of each policy and its execution, this study identifies the key elements--domestic and external--which characterize the policy evolution, and compares those elements in an explication of why Sino-Latin American relations under Deng's regime appear more active than those of Mao's regime. The policies of Mao and Deng differ in the greater emphasis of Deng on the content of government contacts and his greater concern with economic relations, in contrast to the political motivation of Mao.

The purpose of this present investigation was twofold: to determine the relationship between cohesion and performance for successful and unsuccessful bowling teams and to investigate the internal consistency of items from the Group Environment Questionnaire. Subjects were 148 bowling teams (28 men's, 55 women's, 65 mixed--3-5 members each) from 14 different leagues. Results revealed that task cohesion (ATGT) in early, mid, and late season, as well as social cohesion (ATGS) in late season significantly differentiated between high/low cohesion teams. In addition, successful teams (i.e., league position) exhibited significantly higher levels of both task and composite cohesion. All cohesion scales, with the exception of ATGS in early season, revealed a moderate to high level of internal consistency.

Two hundred and fifty-three subjects were used in an experiment to try to determine how differences in news media presentations affect the reader's view of terrorism. Two stories about a terrorist attack were used, one describing a bombing, the other a hijacking. Both stories had two versions using no one injured or eight innocent people injured. One group of subjects was given no additional information about terrorism. The second group was given information after the description that emphasized the salience of terrorism. The third group received information that de-emphasized the seriousness of terrorism. Subjects were also given a questionnaire designed to measure authoritarianism and one to measure conservatism. It was found that subjects scoring high on authoritarianism or conservativism favored more severe punishment for terrorists than did those scoring lower on the two scales. Findings did not support the hypothesis that providing people with information about terrorism could lessen the impact of terrorist events.

Ion chromatography coupled with a conductivity detector was used to investigate the analysis of Cr(III) and Cr(VI) in aqueous samples. An IC methodology for Cr(III) was developed using a cation column and an eluent containing tartaric acid, ethylenediamine, and acetonitrile at pH 2.9. The detection limit of this method can reach 0.1 ppm level with good precision. Several operational parameters were evaluated during the regular use of the method. Comparison of the IC method with AA method showed good agreement between the two methods. The anion exchange column was used for Cr(VI) determination. The best results were obtained with an eluent containing sodium gluconate, borate buffer, glycerin, and acetonitrile. The retention time for the Cr207 2 - sample was 11 min. and the calibration curve was linear between 1.0 and 100 ppm.

Stellar Ouintet is a composition in five movements (Prologue, Allegro, "...Of Stars", Rondo, Epilogue) for two violins, viola, violoncello, and harpsichord. It makes extensive use of constellations , a term used in this work to denote arrangements of pitches in spatial notation. This method of notation is derived from actual astronomical constellations. The score makes use of both real and freely constructed constellations which are rotated around their own central axis. The score is 90 pages long with a 28 page analysis preceding the score. The work has a performance time of approximately 18-20 minutes

Muenster, Texas, in Cooke County, began in 1889 through efforts of German-American colonizing entrepreneurs who attracted settlers from other German-American colonies in the United States. The community, founded on the premise of maintaining cultural purity, survived and prospered for a century by its reliance on crops, cattle, and oil. In its political conservatism and economic ties to the land, Muenster resembled its neighboring Anglo-American communities. Its Germanic heritage, however, became pronounced in the community's refusal to accommodate to the prohibitionism of North Texas regarding alcoholic beverages and in the parishioners' fidelity to the Roman Catholic faith. These characteristics are verified in unpublished manuscripts, governmental documents, local records, and interviews with Muenster residents.

This study suggests that tragedy sees human action as synonymous with language and that it uses a method similar to that of a hermeneutic phenomenology to portray man as experiencing spirituality in a confrontation with expression. This confrontation takes the form of a pattern that leads to a revelation that all human action springs from the spirit. Word as action is thus placed into a spiritual context, containing in itself the key to the divine significance of the human experience. As a cultural manifestation, this pattern exists not only in literary tragedy, but also in the Hebrew Scriptures as narratives and poetry. This study examines this tragic pattern in Genesis, the Book of Job, Oedipus, and King Lear.

Genetic variation was analyzed for populations of seven taxa comprising four cytotypes of the Geomys bursarius chromosome complex, including G. b. major, G. b. knoxjonesi, and the Edwards Plateau taxa, G. b. llanensis and G. b. texensis. Genetic relationships of the Edwards Plateau gophers with other taxa and between themselves were examined. Genetic similarity, number of fixed allelic differences, and ectoparasite distribution indicate the Edwards Plateau gophers are a distinct gene pool. Isolation of the Edwards Plateau taxa precludes contact zone analysis. However, genetic differentiation is typical of that between other species of Geomys, and the Edwards Plateau taxa should be recognized as G. texensis. Distributions of allelic frequencies indicate little justification in retaining the subspecific status of the Edwards Plateau forms.

The research reported here is a study of detector systems to determine those most suited for simultaneous organic acid, inorganic anion determination. Comparisons are made on the basis of detection limits and sensitivities for conductivity, UV/Vis, photoconductivity, and derivative conductivity detection systems. The investigation was made using a constant chromatographic system with the only variable component being the detector system. Eluant optimization conditions for each detector are reported along with tables reporting detection limits and sensitivities for each detector system. Various chromatograms are also shown to provide a visual comparison between detector results.

The purposes of this study were. to identify current uses of computers by university foodservice operations and to determine if there.are any differences in computer use among university foodservice operations. The twelve university foodservice directors who responded to the research questionnaire varied significantly in their computer usage and computer characteristics. Institutions serving more than 1,000 meals per day represented 91% of the sample using computers. Chi Square analysis found a significant use of menu-costing programs. The computers were used more than six hours a day by 75% of the sample. The.problems relating to hardware and software selection indicate a lack of assessment of operational needs for foodservice operations. Guidelines to assist foodservice directors in computerization are needed.

Nucleotide pools were extracted and quantified from Pyr^+ and Pyr^- strains of P. aerucjinosa. Strains were grown in succinate minimal medium with and without pyrimidines, and nucleotides were extracted using trichloracetic acid (TCA; 6% w/v). The pyrimidine requirement was satisfied by uracil, uridine, cytosine or cytidine. Pyr^- mutants were starved for pyrimidines for two hours before nucleotide levels were measured. This starvation depleted the nucleotide pools which were restored to wild type levels by the addition of pyrimidines to the medium. When the pyrimidine analogue, 6-azauracil, known to inhibit OMP decarboxylase, was added to cultures of the wild type strain, the uridine and cytidine nucleotides were depleted to near zero. Thus, the nucleotide pool levels of Pseudomonas strains can be manipulated.
