The lecture recital was given on April 18, 1977. The subject was Adaptation of Handel's Castrato Airs for Bass, and it included a discussion of conventions peculiar to Handelian opera seria, concerns regarding adaptation of Handel's castrato airs and a comparison of adaptation practices in eighteenth- and twentieth-century presentations of Handel's operas. Three coloratura castrato airs and two virtuoso bass airs were performed at the conclusion of the lecture. In addition to the lecture recital, one operatic role and three recitals of solo literature for voice, piano and chamber ensemble were publicly performed. These included the role of "Samuele" in A Masked Ball, by Verdi, performed in English on March 19, 1975 with the Opera Theatre of North Texas State University, a program presented on November 24, 1975,of solo literature for voice, piano, and chamber ensemble, including works by J. S. Bach, W. Mozart, M. Ravel and G. Finzi, a program consisting of a set of works by R. Schumann presented on June 27, 1985, and a program presented on October 28, 1985,of solo literature for voice, piano, and chamber ensemble,including works by A. Caldara, G. Handel, H. Wolf, H. Duparc, C. Ives and S. Barber.

Alan Berg's two musical settings of Theodor Storm's poem"Schliesse mir die Augen beide" have received little in the way of scholarly analytical attention. The three major chapters of this thesis deal with the two settings on three different levels. Chapter II surveys the political and cultural milieu in which Berg functioned as a young composer of Lieder in the years 1900-1910. Chapter III examines the special quality of lyricism which is often attributed to Berg and his works. Chapter IV provides more definitive and complete musical analyses of the two settings than have heretofore been available. The question of what role songwriting played in the development of Berg's compositional process is addressed in the conclusion.

This study examined promoting recorded country music from Atlanta, Georgia, and explored why Atlanta is important in this field. It was learned, through interviews, that promoters wanted radio airplay and top trade publication chart ratings. Radio station program directors decided upon playlists from reading trade publications, efforts by record promoters, listener requests and focus groups, and from reported sales. Stores used album and poster displays, charts, and played music for promotion. The business is one of personalities and experience, as much as product promoted. Large conglomerates are fast changing it.

Companion animals can reduce the elderly person's feelings of isolation and stress, provide tactile stimulation, offer a means of socialization and establish a nonthreatening, nonjudgmental relationship. As an adjunct to treatment, pet therapy may serve to ease the transition from community to nursing home and assist residents in establishing relationships with animals, caregivers, and other residents.

During four growing seasons, aquatic vascular plant production and distribution were studied in Pat Mayse Lake, Texas, a 2425 hectare oligo-mesotrophic reservoir. The dominant macrophyte population was Myriophyllum spicatum L. Growth rates and regrowth rates of mechanically harvested Myriophyllum beds were found to be dissimilar. Based on estimates of watermilfoil nutrient content, there were insufficient nutrients in the entire population to alter the trophic status of this reservoir should all of the nutrients be instantaneously released. Sediments were the primary nutrient (nitrogen and phosphorus) sink. Bank erosion and solids transport from the watershed appear to contribute most of the sediments and a lake-wide mean sedimentation rate of 2.5 cm/year was estimated from sediment trap and core sample data.

The purpose of this study is to shed more light on whether the investment tax credit is effective in stimulating capital investment. The sample includes 104 local cooperatives. The majority of the data was collected from the files of the St. Paul, Minnesota, Bank for Cooperatives. The study has a single purpose of determining whether the changes to the Internal Revenue Code in the Revenue Tax Act of 1978 had an effect on the capital expenditure levels of farm supply cooperatives. In 1978 the investment tax credit became fully available to cooperatives. Previous abatement rules were abolished, and unused credit was then passed through in full to the cooperative membership. The research model employed is a pooled time-series and cross-sectional approach, and includes data for years 1975 through 1983. In addition to capital expenditure data, the company-specific variables are debt/asset ratio, local margin, and net margin. Economic variables are a net interest-inflation rate factor, cash receipts from farming, and loan volume of banks for cooperatives. Also included are dummy variables 0 and 1, trend variables 1-9, and interaction variables for all the main-effects variables.

The attachment and/or penetration of animal cells by two strains of Legionella pneumophila was studied in three vertebrae cell lines in vitro . The study focused on (1) differences in attachment and penetration between the two bacterial strains (an environmental isolate, Johannesburg-2, and a clinical isolate, Chicago-8) and between the cell lines (Hep-2, WI-38 and a murine line); (2) effects of L. pneumophila on cell morphology and growth; and (3) the effects of pyruvate and six sugars or sugar derivatives (D-mannose, D-Galactose, D-Glucose, L-glucose, D-fructose, and 2-deoxy-D-glucose).

Efforts were made to (1) enumerate and isolate the intestinal bacteria of Ascaris suum; (2) identify those bacteria isolated; and (3) assess the ability of intestinal bacteria to produce serotonin.

The purpose of this study was to develop a vocabulary of patterns and motifs based on Persian and Mesopotamian styles. Then, using the characteristics mentioned above, to create a body of work, approximately twenty pieces, using that vocabulary.

The purposes of this study were to determine whether brain growth spurts occur in normal pupils and to determine whether there was a uniform difference in head circumference between boys and girls. Subjects were 3,062 normal elementary pupils, grades one through six, from one suburban school district. Fiberglass measuring tapes were used to measure pupils' head circumference. The hypotheses of the study predicted that the relationship between head circumference and age would be linear. Further, it was predicted that the differences in head circumference between boys and girls would be uniform over seven specified ages. The first hypothesis was tested using a test for linear trend and deviation from linear trend using the General Linear Models procedure. The results indicated that there was a significant linear trend between head circumference and age. The test for deviation from the linear trend was not significant. This would suggest that any deviation from a straight line observed in the data can be attributed to chance. It was concluded that since there was no significant deviation from linear trend, it would suggest a continuous growth of the brain for the ages included in this study. A two-way analysis of variance was used to test …

The purpose of this study was to completely characterize the protein moiety in the caroteno complex in C. poinsettae, determine if the distribution and level of protein in the pigment-protein complex in membranes of the wild type and in a colorless mutant could account for the differences in the stability of the membrane, and to determine if this protein is common to other pigmented and non-pigmented organisms. Also, electron microscopy of cell membranes of C. poinsettiae which had been exposed to gold-labelled antibody against the protein moitey of the pigment-protein complex, demonstrating that the protein is randomly distributed in the membranes of both wild type and colorless mutant.

The problem motivating this research is that ineffective communication may hamper systems development efforts. Specifically germane to this study are development efforts characterized as task-oriented, and which require information-sharing and problem-solving activities. This research problem motivated an analysis of the communication process and lead to the development of a temporal framework that delineates variables associated with task-oriented, end user/systems analyst communication interactions. Several variables within this framework are depicted in two theoretical models. The first model shows the theoretical relationship between an independent variable, communication mode (represented by asynchronous computer conferencing and face-to-face conferencing), and five dependent variables: (1) the amount of information shared, (2) the significance of the information shared, (3) the comprehensiveness of the information shared, (4) the perception of progress toward the goal, and (5) the perception of freedom to participate. The second model depicts the assumed interaction between communication mode, the five variables cited above (now acting as independent variables), and a dependent variable, communication quality. There are two theoretical components of communication quality: (1) deviation from an optimal set of user requirements, and (2) the degree of convergence (unity based on mutual understanding and mutual agreement) emanating from a communication interaction. Using the theoretical models …

The purpose of this study is to provide empirical evidence relevant to perceptions of internal auditor independence. Specifically, this study investigates how the auditor practitioners (both internal and external auditors) perceive the importance of five selected factors that characterize the organizational settings of an internal audit department. Role theory is the frame of reference used to develop the conceptual model for this study in which the judgment of internal auditor independence is viewed as the role perception of internal auditors. A modified version of the Brunswik's lens model was developed to provide "paramorphic" representation of judgment of independence. The research methodology of this study is based upon a laboratory experiment in which a replicated factorial design was used to elicit the subjects' judgments of independence. The data collected from this experiment were analyzed by three statistical methods: conjoint measurement, multiple regression, and cluster analysis. The major findings follow. First, the five selected factors were not perceived as equally important by the subjects. In general, internal auditor's scope of audit. scope o^ service, and reporting level were perceived as more important than adequacy of organizational support. and formalization of audit policies. Second, the two groups of auditors disagree, significantly, on the …

The purpose of this study is to compare and analyze the teaching of history in teachers colleges in the Metropolitan region and other regions in Thailand. Variables examined in this study include the following: salary, teaching experience, degrees held, the number of graduate credit hours in history, the number of graduate credit hours in education, attendance at professional meetings, the number of publications, membership in professional organizations, the number of hours devoted to course preparations, teaching load, and teaching behaviors. The comparison is based on geographical location of the teachers colleges by region. The survey instrument, after intensive review and validation by selected faculty both in Thailand and the United States, was distributed to the 180 history instructors in the teachers colleges in the six major regions of Thailand. The total number of responses was 138, or 76.7 per cent. The statistical procedures used in the analyses of data include frequency and percentage of responses, a chi square test of independence, t test, the Yates* correction for continuity, and Fisher's Exact Probability Test (2-tailed). The data findings from this study indicate that there is a high degree of similarity between the respondents from the Metropolitan region and other regions' history …

The problem addressed in this study is the need for efficient and economic methods to train naive college students to operate microcomputers as a necessary step in their acquisition of computer proficiency. Two methods of training were compared. These were training by live demonstration and training by videotape. These methods were considered economically viable because each could be presented in a classroom and neither required a one-to-one student-to-computer or student-to-tutor ratio. Four sections of an introductory computer science class were used in the study. Two classes were presented each treatment. The effectiveness of the presentations was measured by means of a written quiz administered immediately after the presentation and by the number of microcomputer system operation tasks successfully completed during an individual laboratory session. The computer anxiety level of each participant was measured prior to the presentation to determine if anxiety was a factor in finding the best training method. When scores of naive users who saw the videotape were compared with the scores of naive users who saw the live demonstration, no significant differences were found. However, when novice users (those who had some previous experience with operating or programming a microcomputer) were included, the group that saw the …

The problem with which this investigation is concerned is that of identifying and prioritizing the competencies required to design and implement manufacturing systems for advanced composite structures. The classical Delphi procedure is the research method used for the conduct of this study. A five-member advisory board developed a list of seventeen categories under which the competencies would reside. In the first-round questionnaire, the seventeen categories were presented to a Delphi panel of experts who provided up to five competencies required in each category. The first-round returns provided two new categories and 973 competency statements. Duplications were eliminated and 366 competency statements remained in nineteen categories. The second, third, and fourth rounds were a reiterative rating process. The panel was asked to rate the items in the questionnaire based on their relative importance to the intent of the study. The importance rating scale included "very important," "important," "slightly important," and "unimportant." The means and interquartile ranges were calculated for each statement and provided as feedback in the successive round. Kendall's coefficient of concordance W for tied ranks was used to validate the panel consensus. The W was significant at the .01 level for each of the three rounds where rating was …

The problem of this study was to investigate the strategies used by high school students of limited estimation ability for the estimation of the answers to computational problems. The Assessing Computational Estimation Test was administered to 460 students, and 40 of them were selected for interviews. Each student interviewed was asked to estimate the answers to fourteen computation and application problems.

The Concert for Guitar and Chamber Orchestra, a three-movement work, is approximately seventeen and one-half minutes in duration. Adhering to the three movement concerto form, the work reflects the influence of several styles of twentieth-century orchestral music. In the first movement, two principal motives, significant throughout the work, are developed in a series of metered and non-metered events. The second movement consists of a set of guitar cadenzas framed by increasingly complex material in the orchestra. The third movement explores an application of the two principal motives in a rondo setting.

Let L be a lattice. For x ∈ L, we say x is a consistent join-irreducible if x V y is a join-irreducible of the lattice [y,1] for all y in L. We say L is consistent if every join-irreducible of L is consistent. In this dissertation, we study the notion of consistent elements in semimodular lattices.

A total of 60 school psychologists and educational diagnosticians across Texas completed a survey to identify the instruments used to screen and diagnose learning disabled (LD) students, and to identify the criteria on which the final diagnosis and placement of LD or non-LD is made. The results of this survey indicate that consistent methods and criteria are not being used for identifying children as LD within the state. Many of the instruments currently used may not be technically adequate for use with a LD population. Implications of the use of inconsistent criteria, inadequate screening and assessment measures are discussed.

The dissertation consists of four recitals: repertoire consisting of solo compositions, music for clarinet alone, chamber music, and one lecture recital. The repertoire of these programs was chosen with the intention of demonstrating the capability of the performer to deal with problems arising in works of varying types and of different historical periods. The lecture recital, The D Major Clarinet Concerto by Theodor von Schacht, discusses background for the development of the clarinet in different pitches and gives pertinent bibliographical and historical information on the life and works of Theodor von Schacht. A formal and stylistic analysis is then followed by a short discussion of the problems involved in the transcription and performance of the work: possibly the first solo concerto ever written for the clarinet in A. The lecture concludes with the first performance of The D Major Clarinet Concerto for clarinet in A with orchestral accompaniment reduced for piano.

Philosophical and physiological investigations define thought to be the result of thinking. psychological Inquiry has mainly focused on discovery of the mechanisms and topology of thought. Philosophical Inquiry either has explored the mind-body problem or has analyzed the linguistics of the expression of a thought. However, neither has Investigated adequately phenomenal characteristics of thought Itself, the Intermediary between the production and the expression of a thought. The use of thought to analyze phenomenal characteristics of thought engenders a paradox. If the expression of thought requires finite series of linked words with rules governing syntax, then analysis of both the thought and the expression of the thought must necessarily transcend the linguistic level. During the last century many examples of logical paradoxes In linguistics of thought have been given. The culminating difficulty of dealing with a finite structure, a characteristic of any language, Is Godel's Incompleteness Theorem, which says in essence that in order to render all decisions about a finite system requires the use of material outside the system. Thus, a potentially complete interpretation of thought must use some technique which is basically non-linguistic . Wittgenstein proposed such a method with his "Picture theory. " This technique solves the major …

The purpose of this study is to identify and compare the perceptions of practicing teachers and college instructors toward four components of inservice education programs: content, organization, format of presentation, and participant involvement in the teachers colleges in Thailand. The comparison is based on the demographic variables of sex, age, educational background, and teaching experience in the institution. The "In-Service Education Attitude Survey" by Yesuratnam, Basimalla at the University of Illinois at Urbana-Champaign, Urbana, Illinois in 1982 was used to gather data for this study. It was distributed to a sample of 380 practicing teachers and college instructors in 19 randomly selected teachers colleges in Thailand; 368 usable instruments were returned (97.15%). The data were treated to produce numbers and percentages. The t tests for two independent samples were computed to determine any statistically significant differences between the respondent groups of practicing teachers and college instructors, and between the practicing elementary and secondary school teachers. The F tests were also utilized to determine any statistically significant differences among the variables of practicing teachers and college instructors.

Psychological research suggests that Ritalin reduces the rate of maladaptive behaviors in hyperactive children but does not improve their academic performance. Teachers, however, often assert that writing skills and other graphic work are improved by Ritalin. Twenty elementary school children who had been diagnosed as hyperactive and who were taking Ritalin were tested using WISC-R coding, WISC-R block design, and Bender Gestalt. Ten of the subjects were assigned to a group which was first tested when the children were off Ritalin and subsequently tested when they were on Ritalin. The sequence was reversed for the remaining ten. This procedure was designed to counterbalance the effect of practice. Direct difference t-tests indicated that there were no differences between groups regarding any of the three dependent measures. Thus, results indicate that the popular conceptions among educators regarding the efficacy of Ritalin for improving visual-motor efficiency is open to serious question.
