One purpose of this investigation is to determine the fatty acid and lipid content of typical Vibrio cholerae cells. The comparison of cholera lipid constituents with those of closely-related bacteria might be of taxonomic value. Furthermore, chemical characterization of the cholera vibrio could provide useful criteria for identification of these disease-producing microorganisms.

The purposes for conducting this study were to ascertain whether the housing for industrial arts metalworking laboratories was adequate, whether the enrollment of the school showed any correlation with the availability of a metalworking facility, and to what extent the physical facility for metalworking laboratories met current standards.

The problem with which this investigation is concerned is that of determining the predictors, correlates, and consequences of job satisfaction in a university library. A managerial model was constructed for the purpose of providing an overall framework of analysis. It was hypothesized, in the managerial model, that organizational effectiveness in any organization is linked closely to the concepts of job satisfaction and employee satisfactoriness. These two concepts, in turn, are closely related to managerial behavior.

The problem with which this investigation is concerned is that of developing a scale for rating a public school superintendent in Texas in terms of his adherence to selected characteristics of administrative leadership. A secondary problem is to verify the hypothesis that very few schools in Texas, if any, use a rating scale to evaluate the performance of the superintendent. The purpose of this study will be to identify a set of administrative leadership characteristics which are accepted by members of Boards of Trustees, professors of educational leadership, and superintendents.

The purposes of this study are to identify and describe the function and control of facial muscles as related to sound production on brasswind instruments, to explore electromyographic theory and techniques with particular regard to the function and control of facial muscles, to identify basic theories of embouchure among brasswind teachers and performers, to develop a theory of brasswind embouchure based upon the preceding factors, and to propose recommendations with regard to brasswind pedagogy. Existing theories of embouchure were investigated by reviewing the extensive brasswind pedagogical literature, and by interviewing teachers representing two widely differing views. Electromyographic kinesiology of facial muscles was investigated as follows: a description of facial muscles was formulated by collating anatomy books; related electromyographic literature was reviewed; eloctromyographic recordings of facial muscled during, the performance of various facial muscle tasks and during brasswind performance were made using indwelling fine-wire electrodes. The following fundamental questions were raised: (1) What are the elements of brasswind embouchure, and what is the effect of each upon performance? (2) Is there a single embouchure mode which may be considered most efficient, and if so, what facial muscles are involved, and how may they be trained?

The purpose of this study was to determine the effects that certain classroom management techniques would have on the self concepts and choice status of sixth grade students and to assess the potential of these techniques. All sixth grade students (86) enrolled in one elementary school participated in this study. There were four class sections, two of which made up the experimental group and two of which made up the control group. Only those students who were enrolled at the beginning of the study were included in the final data analysis. The IPAT Children's Personality Questionnaire, What You Do and What You Think (1963) provided a measurement of self concept. This instrument was reported to be a standardized self evaluation scale that assessed fourteen factors of personality. The sociometric test of specific criteria was used to identify students of low choice status. These two instruments were administered in January of 1972 and again in May of 1972.

The problem with which this investigation is concerned is that of presenting a concise English translation of the book which Martin Agricola wrote in 1528 in German on the musical instruments and practices of his time. In addition to the translation itself, there is a major section devoted to a comparison of the material of Musica instrumentalis deudsch with other books and treatises on the same and related subjects which were written at approximately the same time or within the next hundred years. Agricola states that the purpose of his book was to teach the playing of various instruments such as organs, lutes, harps, viols, and pipes. He also noted that the material was prepared expressly for young people to study. To facilitate the accomplishment of this purpose Agricola wrote the book in short, two-lined, rhymed couplets so that the youths might quickly memorize the material and thus retain the instructions better.

This study is limited to the mathematics performance of two intact groups of culturally deprived kindergarten students, mostly blacks, with a few whites and Mexican-Americans, who were enrolled at Robert E. Lee Elementary School (Denton, Texas) for the entire school year of 1970-1971. The purposes of the study are to compare the effectiveness of two methods of teaching mathematics to culturally disadvantaged children and to check for interaction of treatments when these children are classified by sex.

The purpose of this experiment has been to complete a challenging thesis production in the style and technique of Open Theatre, utilizing imaginative production effects. The purpose was also to provide a valuable experience for those actors and technicians involved, meeting the standards and requirements of educational theatre. The experiment evolved from adapting, designing, directing, and producing a twelve scene cutting from Megan Terry's Viet Rock and twelve episodes from Jean-Claude van Italliets The Serpent. The study was culminated with a one-evening performance of The serpent and Viet Rock on August 10, 1971. The style and technique of Open Theatre seemed to be well accepted and fulfilled the requirements which the script demanded. The reaction of the audience seemed to indicate that the response sought by the Comp any was accomplished. The conclusion may also be drawn that this experimental production was successful not only as art, but also as an evening of entertainment.

Dealing with the college laboratory program in general chemistry, this study compares the effects of exercises based on current national problems with the effects of traditional laboratory exercises. The study has been prompted by the recent emphasis on topics of national interest in the undergraduate chemistry curriculum. These topics include air and water pollution, drug addiction and analysis, tetraethyl-lead additives, insecticides in the environment, and recycling of wastes. The relevant experiments are taken from recent issues of the Journal of Chemical Education. The traditional exercises, from the laboratory manual Chemistry in the Laboratory, by Watt, Hatch, and Lagowski (New York, Norton, 1964), deal with such topics as chemical composition, gas laws, solutions, and acids and bases.

A unique undosciribed gramnegative rod is extensively characterized in this study. The cells of this unusual water isolate measure 1.2 X 6.5 microns, The most distinguishing characteristic of the bacterium is a polar tuft of 35-40 flagella that aggregate to function as a single organelle which is visible under phase contrast. Aging cells deposit poly- -hydroxybutyric acid granules which are bound by an inclusion membrane made up of four distinct layers. It also possesses an unusual exterior membrane outside the cell wall which contains large fibrils of protein running at a slight angle to the longitudinal axis of the cell. The guanosine-cytosine ratio was found to be 62.2$. The organism's taxonomic position was further investigated by immunological, morphological, and biochemical methods. It was found to be most closely akin to members of the genus Pseudo onas, although somewhat divergent from other species classified in this genus. After careful evaluation of the findings obtained during this study, the new bacterium was subsequently named Pseudomonas multiflagella.

The problem with which this investigation is concerned is that of facial muscle activity in forming and maintaining the soprano clarinet embouchure. The purposes of the study are to collect and analyze data in the following areas: 1. Activity of the following muscles during performance on the clarinet: (1) upper orbicularis oris, (2) lower orbicularis oris, (3) upper half of the buccinator, and (4) lower half of the buccinator. Muscular activity is read as electronic potential and is presented on recordings through the use of electromyography. 2. Possible effects which the electromyographic apparatus might impose upon performance. Tape recordings weremade of the subjects' performing prescribed tasks both before and during electromyographic analysis. The possible effects of the electromyographic analysis upon performance were then tested by comparing these two recordings.

One of the newest organizational developments in the junior college world is the multicampus junior college system. The purpose of this study was to determine whether there is a difference in the understanding of authority relationships between chief district administrators and chief campus administrators in multicampus junior college systems. This information should be valuable to junior college administrators who are now, or will be, faced with the problem of clarifying this authority relationship in daily activities and future planning. The semantic differential was the measuring instrument used in this study. Its use required that a questionnaire be developed to include functions to be differentiated against a set of corresponding bi-polar adjectives. The functions selected were evaluated by several individuals experienced in multicampus junior college administration. The nine pairs of bi-polar descriptive adjectives selected were from general adjectives previous factorial studies showed to have high factor loadings on either the evaluative, potency, or activity dimensions of connotative meaning.

The problem with which this investigation is concerned is that of determining the effects of videotaping and subsequent playback on the communication performance of introverted and extroverted individuals. The principal method of determining these effects is the subjective judgment of a panel of qualified speech instructors who viewed videotaped speeches made by the subjects. All subjects were repeatedly subjected to videotaping, and half were exposed to playback. Statistically, by using one-way analysis of covariance, the effects of playback were measured: The speaking scores achieved by the experimental introverts and extroverts were compared with the speaking scores of the control introverts and extroverts. Sixty-four subjects were used; these were limited to college students enrolled in the teacher-education program. To carry out the purposes of the study, the following hypotheses were tested: 1. There will be a significant difference between the scores of introverted trainees who are videotaped and exposed to playback and the scores of introverted trainees who are videotaped but not exposed to playback. 2. There will be a significant difference in the scores of extroverted trainees who are videotaped and exposed to playback and the scores of extroverted trainees who are videotaped but not exposed to playback.

The lecture recital was given October 15, 1971. The subject of the discussion was Brahms and the Character Piece: Emotion Guided by Intellect, and it included historical and biographical information, an analysis of Brahms' romantic-classic style, a general analysis of the six character pieces in Opus 118, and performance of Opus 118 by memory. In addition to the lecture recital, three other public recitals were performed. These three programs were comprised of solo literature for the piano. The first solo recital was on April 15, 1971, and included works of Brahms, Chopin, Mozart, and Ravel. The second program, presented on April 28, 1972, featured several works of Beethoven. Performed on Septemhber 25, 1972, the third recital programmed compositions by Chopin, Debussy, and Prokofieff. Magnetic tape recordings of all four programs and the written lecture material are filed together as the dissertation.

The problem with which this investigation is concerned is that of providing a current academic and racial description of the intercollegiate football participants at North Texas State University and the construction of a current participants' profile. The subjects employed were 259 football participants from the 1966 Fall Semester through the 1971 Fall Semester, The descriptive analysis is based upon 234 participants; the profile is a composite of eighty-one currently (1971) enrolled participants, This study has a twofold purpose, The first is to provide a current description of the academic status of both white and non-white participants; the second is to construct a current profile of the participants, The study is designed with the idea that the findings could be of use to coaches and administrators of this university in football programming, Transcripts, coaches, and the Public Information Office of this university provided the data used in the descriptive analysis, Eighty-one participants answering self-report questionnaires provided data for the profile,

The purpose of this study was to develop a probabilistic model that could be used by petroleum refiners to evaluate the economic potential of refinery capital investment proposals. The following two requirements were placed on the development at the outset: (1) that the model use linear programming to simulate refinery operations; and (2) that the model keep computer time within reasonable bounds. A probabilistic model was developed that requires the following steps for its application: (1) use linear programming to simulate both the operations of the existing refinery and the operations assuming that the investment is made; (2) select two variables that can be treated as probabilistic variables and assign either a theoretical or a subjective probability distribution to represent future values for the two variables; (3) develop return on investment interpolation data by computing a return on investment for all pair combinations of three tenth year values for each of the two probabilistic variables; (4) develop a return on investment distribution by selecting values at random from the two probability distributions and interpolating among the interpolation data to obtain return on investment data; (5) interpret the return on investment distribution. The model was applied to an actual refining situation …

The problem of this study is that of comparing certain physical fitness and anthropometric measures for early adolescent Mexican-American and Anglo-American males. The purposes of the study are to determine if Mexican-American and Anglo-American males differ in physical fitness or anthropometric measures; to determine if the relationships between age and physical fitness, age and arthropometric measures, and anthropometric measures and physical fitness items are significantly different for Mexican-American and Anglo-American males; to compare the rate of maturation for pre-adolescent Mexican-American and Anglo-American males in physical fitness items and anthropometric measures.

The study involves the distribution of an opinionn-aire to one hundred public high school counselors, one hundred public high school principals, sixty-three counselor-educators, and forty-two administrator-educators. A return percentage of seventy-nine has been realized.

This investigation is concerned with determining the extent of inservice education provided for special education personnel by the five pilot programs of Plan A. The two methods of determining this involvement are a case study of the pilot programs' inservice education and its relationship to resource agencies such as the Texas Education Agency and Regional Education Service Centers. The purposes of this study include the following: (1) determining the principles underlying the philosophy formulated by school district personnel in regard to the nature and purpose of inservice training for Plan A, (2) identifying the nature, scope, and assessment of a three-year period of inservice education for the pilot Plan A programs, (3) identifying the successful components of and the problems encountered during the three-year period of inservice education, and (4) describing recommendations for future inservice education. Only the five pilot districts are described in the case studies of Plan A programs. Data is reported in the following sequence for each of the pilot districts: background information; philosophy and goals; pre-, in-, and post-service activities for 1970-1971, 1971-1972, and proposals for inservice education for 1972-1973. Also reported is information concerning the role of the Texas Education Agency and the Regional Education …

An examination of the stanzas of The Faerie Queene reveals a structural complexity that prosodists have not previously discovered. In the prosody of Spenser's epic, two formal prosodic orders function simultaneously. One is the visible structure that has long been acknowledged and studied, eight decasyllabic lines and an alexandrine bound into a coherent entity by a set meter and rhyme scheme. The second is an order made apparent by an oral reading and which involves speech stresses, syntactical groupings, caesura placements, and enjambments. In an audible reading, elements are revealed that oppose the structural integrity of the visible form. The lines cease to be iambic, because most lines contain some irregularities that are incongruent with the meter. The visible structure is further counterpointed by Spenser's free use of caesura and frequent employment of enjambment to create a constantly varying structure of different line lengths in the audible form. This study also examines precedents that Spenser could have known for the union of music and poetry. English lyric poetry written for existing melodies is analyzedand the French experiments with quantitative verse supported with musical settings are discussed. Special emphasis is given to the musical associations of the Orlando furioso, particularly its …

The problem of this study was to develop a proposal for the teaching of poetry for the purposes of contributing to the student's understanding and enjoyment. Surveys and summaries were made of scholarly writings on the junior college student, existential theories of education, and theories of poetry. A bibliography was constructed for each subject from resources of the North Texas State University library. Conclusions from each survey were derived from the selected resources and used to prepare the proposal for instruction of poetry.

Many mathematical programming models of the selection of investment portfolios assume that the best portfolio at any given level of risk is the portfolio having the highest level of return. The expected level of return is defined as a linear combination of the expected returns of the individual investments contained within the portfolio,and risk is defined in terms of variance of return. This study uses Monte Carlo simulation to establish that if the estimates of the future returns on potential investments are unbiased, the steady-state return on the portfolio is overestimated by the procedure used in the standard models. Under reasonable assumptions concerning the parameters of the estimates of the various returns, this bias is quite sizeable, with the steady-state predicted return often overestimating the steady-state actual return by more than ten percentage points. In addition, it is shown that when the variances of the alternative potential investments are not all equal,a limitation on the variance of the portfolio will reduce the magnitude of the bias. In many reasonable cases, constraining the portfolio variance reduces the bias by a magnitude greater than the amount by which it reduces the predicted portfolio return, causing the steady-state actual return to rise. This …

This study examines the relations of white Baptists with racial and ethnic minorities in Texas from the beginning of organized Baptist work in Texas in the mid-nineteenth century, through the United States Supreme Court decision in the Brown v. Topeka case in 1954, Emphasizing the role of attitudes in forming actions, it examines the ideas of various leaders of the chief Baptist bodies in Texas: the artist General Convention of Texas, the Baptist Missionary Association of Texas and the American Baptist Convention. The minorities included in the work are the Negroes, the Mexican-Americans, non-Anglo-Saxon Europeans, American Indians, Orientals, and Jews. Several factors tend to justify a study of this subject. First, there is the prominence of race relations in the nation which has aroused interest in the effect which race relations have had upon affairs in Texas, Second, the widespread changes which have taken place in Texas during, the last two decades suggest the feasibility of a study of that phenomenon, and the fact that many consider the race problem to be a moral and religious issue indicates the relevance of the churches' relationships to these changes. As the largest religious denomination in the state, the Baptists offer a viable …
