Lipids and Phospholipase Activity of Vibrio Cholerae: 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.
Predictors, Correlates, and Consequences of Job Satisfaction in a University Library: 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 Development of a Rating Scale for Use by Texas School Board Members to Evaluate a Superintendent's Performance: 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.
A Theory of Brasswind Embouchure Based upon Facial Anatomy, Electromyographic Kinesiology, and Brasswind Embouchure Pedagogy: 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 Effects of Classroom Management Techniques of Students' Choice Status and Self Concepts: 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.
Martin Agricola's 'Musica Instrumentalis Deudsch': A Translation: 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.
The Effectiveness of a Structured Mathematics Program with Culturally Deprived Kindergarten Children: 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.
A Focus on Problems of National Interest in the College General Chemistry Laboratory: The Effects of the Problem-Oriented Method Compared with Those of the Traditional Approach: 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.
The Isolation and Characterization of a Hitherto Undescribed Gram-Negative Bacterium: 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 Activity of Certain Facial Muscles in the B-Flat Soprano Clarinet Embouchure: An Exploratory Study Utilizing Electromyography: 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.
An Analysis of the Understanding of Authority Relationships Between Chief District Administrators and Chief Campus Administrators in Multicampus Junior College Systems: 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 Effects of Videotaping and Playback on the Communication Performance of the Introverted and Extroverted Individual: 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.
Brahms and the Character Piece: Emotion Guided by Intellect, a Lecture Recital, Together with Three Recitals of Selected Compositions by Beethoven, Brahms, Chopin, Debussy, Mozart, Prokofieff, and Ravel: 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.
A Descriptive Study of Intercollegiate Football Participants at North Texas State University: 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,
A Probabilistic Model for Evaluating Capital Investment Proposals for Petroleum Refineries: 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 that involved determining the expected internal rate of return of a proposed hydrocracker addition to a United States refinery. Total computer time required to evaluate the hydrocracker proposal was about 159 minutes. Accuracy of the interpolation feature of the model was also determined during the application. The average error of ten interpolated return figures that were selected at random for the accuracy check was 1.89 per cent.
A Comparison of Physical Fitness and Anthropometric Measures of Pre-Adolescent Mexican-American and Anglo-American Males: 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.
Role Expectations of the Texas Public High School Counselor as Perceived by Various Professional Groups: This study seeks as its purpose to establish an .objective evaluation of the counselor and his role as seen by various professional groups. The primary purpose of the investigation is to compare the perceptions of these various groups as to the tasks a counselor may perform. 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.
A Case Study of Selected Plan A Special Education Inservice Programs in Texas: 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 Service Centers in relationship to Plan A implementation and inservice education.
"A Straunge Kinde of Harmony": The Influence of Lyric Poetry and Music on Prosodic Techniques in the Spenserian Stanza: 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 relation to the tradition of singing narrative poetry to folk melodies. Internal support for the thesis that Spenser deliberately employed musical techniques in his prosody comes from his use of the Tudor masque in the structure of the epic. Evidence is offered to show that the processional masque is the unifying foundation for the whole of The Faerie Queene, A characteristic of the sixteenth-century masque was its combination of art forms, and Spenser found a method for integrating the arts of music and literature. Spenser uses musical techniques in the prosody that he could have expected would echo musical experiences …
A Proposal for Instruction of Poetry at El Centro College: 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.
An Inquiry into the Inevitability of Prediction Error in Investment Portfolio Models: 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 implies that return cannot automatically be assumed to be a monotonic function of risk.
Baptists and Racial and Ethnic Minorities in Texas: 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 subject for study. Finally, since to date no study specifically relating to the Baptists of Texas and their role in race relations in the state has been made, it is felt that such a study will contribute to an understanding of the situation. The scope of this study, in point of time, extends from about 1850 to the early 1960's, in order to consider the reactions of Texas Baptists to the Brown decision of the United States Supreme Court. From the standpoint of subject, the study has been limited to leaders of the Baptist denomination. Their statements on the race …
Effects of a Learning Center Method Versus Lecture Method of Teaching as Related to Achievement, Self-Concept, and Attitude of College Freshmen: The major problem of this study involved a comparison of two methods of teaching English and biology to college freshmen. Subproblems investigated in this study involved the apparent influence of each method of teaching on achievement in each course, on the self-concept of the student, on the students' attitude toward college and toward the learning center, and the effect of the commuterresident status on achievement, self-concept, or attitude. The purpose of this study was to assess the efficacy of the experimental method of teaching to achieve desired growth in academic achievement of first-semester college freshmen enrolled in English or biology.
The Refinement of a Policy-Capturing Model Used in the Selection of Administrative Interns: The problem of this study is to refine the "policy-capturing" model used in the selection process of interns for the Administrative Leadership Training Program in a large metropolitan school district. The subjects for this study consisted of 416 candidates over a three-year period. The statistical procedure of multiple linear regression analysis was used to test the hypothesis that it would be possible to model the decision-making process so that the predictive value would be 90 per cent or higher. During the refinement process, the unique contribution of variance accounted for by each predictor variable was examined,and interactions between certain variables were tested. Two refined models were formulatedand the predictive value of each was calculated. The predictive values of all the models were less than 90 per cent; therefore, the hypothesis was rejected.
The Separation of Rehabilitation from Production Costs in the Vocational Rehabilitation Workshop: The problem with which this study is concerned is the separation of rehabilitation from production costs in vocational rehabilitation workshops. Within workshops there are those functions and tasks—testing, counseling, and the administration thereof—which clearly are rehabilitative. The costs of these activities, therefore, are solely rehabilitation costs. In the production area of workshop operations, however, where production and rehabilitation efforts are intertwined, two kinds of costs are incurred simultaneously: (l) rehabilitation or training costs and (2) production costs. As yet, no generally accepted procedures exist for separating these joint costs.
A Study of Contemporary Franchising, with Particular Emphasis on Factors Leading to the Repurchase of Fast-Food Service Franchises: This study explores the question of whether repurchasing of service establishments is an inherent characteristic of service franchising. The answer to this question holds substantial consequences for the economy and for public policy toward franchising.
The Effects of Audiotape Suggestions on Study Habits, Self-Concept, and Level of Anxiety among College Freshmen: The study examines the use of hypnotic audiotapes designed to affect study habits and attitudes. It is assumed that exposure to the hypnotic audiotapes will improve study habits and attitudes. It is further expected that exposure to the audiotapes will improve students' self-concepts and adjustment to college work, as well as reduce anxiety. Previous studies are cited which indicate that hypnosis has had a positive effect on learning. Hypnosis has been shown to be an effective means of changing specific behaviors.
The Arnspiger Value-Oriented Rationale and General Education for Student Self-Understanding and Continuous Self-Development: The problem of this study was to describe a conceptual design for general education with interdisciplinary qualities leading to student self-understanding and continuous self-development. This study emerged out of the need to gain some insight into the causes of decline and/or abandonment of general education programs during periods of social disorganization, and to determine whether a relationship.exists between mounting social problems and the more intense kinds of problems experienced by college-age youth during these periods.
A Model for a Speech and Drama Program for an Upper-Division College: Tyler State College: The problem of this study is that of developing a speech and drama program for Tyler State College which is consistent with the philosophical framework of the college as well as with the scope of upper-division institutions in Texas as stated by the Coordinating Board, Texas College and University System. Emphasis is placed on the matriculation of students from junior colleges within commuting distance of Tyler.
Life of the Enlisted Soldier on the Western Frontier, 1815-1845: In contrast to the relatively rapid changes occurring in the modern American army, the period between the end of the War of 1812 and the beginning of the Mexican War offers a definite period for a study of military life when reform came slowly. During the period of study, leaders made few attempts to reform the general structure of the military institution as a social system. On the other hand, many changes can be discerned which improved weaponry and equipment, tactics, supply and administrative procedures, moral guidance, recreational facilities, and pay.
A Comparison of Selected Arkansas North Central Association Secondary Schools Using the Evaluative Criteria: The purpose of this study was to report the evaluation ratings and describe the Arkansas NCA secondary schools, as indicated in the Summary Reports of the Evaluative Criteria, 1960 edition, and to compare ratings on all sections and divisions, section D-J, by size classifications.
An Analysis of the Mathematics Necessary for a Course in Research Statistics for the Behavioral Sciences: This study attempted to determine the specific mathematics necessary to a student in a beginning course in behavioral science research statistics. To determine the most desirable form for a review of mathematics prior to a research statistics course,, it was first necessary to determine the following: (1) the specific overall content of such a course, (2) the specific mathematics topics of such a course, and (3) the specific mathematics operations utilized in such a course. The study consisted of three parts. The first phase was a determination of the content of a typical beginning course in research statistics for the behavioral sciences. To make this determination, a survey was conducted among forty universities chosen by random sampling from those in the United States offering the Doctor of Education degree. Course outlines and textbooks used by these universities were analyzed, and topics were tabulated. In addition, a selection of recent statistics texts was analyzed, and these topics were also tabulated. These tables were used as a means of content determination.
A Study to Determine the Impact of Unscheduled Priority Tasks on Organizational Size: This study is directed to the problem of the quantitative determination of the number of additional personnel required in an organization for servicing unscheduled priority tasks without delaying the completion of scheduled tasks. The manager of an organization which has been enlarged in order to respond adequately to the random arrival of priority requests may face criticism if the organization appears to be "overstaffed" during periods when only "routine" service requirements must be met. An audit team oriented toward accounting-type data may be reluctant to accept a manager's justification of his organization's size if the justification is based primarily on nonquantitative arguments.
Existing Relationships Between Enrollment Size and Methods of Financial Management in the Public Universities of Texas Participating in the Ad Valorem Tax Fund: The problem of this study is to ascertain the existing relationships between enrollment size and methods of financial management in selected public institutions of higher education. The purposes set forth for this investigation are to conduct a survey of the financial management methods of a major segment of Texas higher education, to analyze the existing relationships of these financial methods with increasing enrollments ranging from 2,537 to 26,531, and to assess the implications thereof for indicators of optimum and maximum enrollments under variable methods of financial management.
A Case Study of Parental Involvement in the Initial Plan "A" Public School Districts in Texas: The problem of this investigation is a case study of parental involvement in the initial Plan A public school districts in Texas. The components of parental involvement isolated for the study are parent education, parent participation, and parent counseling. The major sources of data are questionnaires distributed to parents, teachers, and administrators in the initial Plan A public school districts. Secondary sources of data include interviews with the three categories of respondents to the questionnaires, communication and correspondence with the Regional Education Service Centers, and correspondence and reports from the Texas Education Agency concerning parental involvement. The purposes of the case study of parental involvement are (1) to analyze the various approaches to provide parent education services in the selected Plan A programs, (2) to analyze the various types of parent participation in the initial Plan A programs, (3) to analyze the existing and projected needs for parent counseling in Plan A, (4) to summarize findings into recommendations for effective parental involvement strategies in future implementations of Plan A in Texas, and (5) to suggest modifications or to raise questions for further investigation.
The Effect of Personality Characteristics on Information Selection, Utilization and Decision-Making: The problem with which this investigation is concerned is that of determining the role of personality in information acquisition and utilization during the decision-making process, by replicating the Schkade-Scarborough box design and the Kernan-Mojena chip design, using an expanded battery of psychological tests. This investigation seeks to accomplish the following objectives: (1) review and summarize the present literature which relates personality and binary decision behavior; (2) review and summarize the present literature which relates personality with information transmission and utilization; (3) administer the Minnesota Multiphasic Personality Inventory (NMPI), the Gordon Personal Inventory (GPI), the Gordon Personal Profile (GPP), EAS j, and LA1S0 to a group of subjects who will also participate in both the box and the chip experimental designs; (4) replicate both the box and the chip experimental designs with a different set of subjects to test for consistency of findings; (5) perform canonical analysis on the box design, endeavoring to extend and refine the analysis of the data; and (6) compare the findings from the box and chip experimental designs, and identify areas for further research. The purpose of this study is twofold. The first is to replicate and test the research findings of Schkade-Scarborough and Kernan-Mojena, which suggested that there is a statistically significant relationship between decision performance, as defined by a set of decision performance metrics, and personality, as defined by a set of psychological test scales. The second purpose is to test the hypothesis that the same psychological scales which are significantly related to decision performance, as defined by the box performance metrics, are also related to decision performance, as defined by the chip performance metric.
Mexican Americans: An Economically Significant Ethnic Market Segment: The area of ethnic market segmentation has received little attention from practitioners or academicians of marketing since most minority groups immigrating to the United States have gradually assimilated the cultural norms and values, and thus the market behavior, of the American society as a whole. Preliminary investigation, however, indicates that Mexican Americans are an exception. To discover whether Mexican Americans represent a true ethnic market segment of economic significance, this study examines and analyzes several aspects. First, to determine whether Mexican Americans represent a true ethnic segment, the following aspects of their cultural norms, perceptions, and values are investigated: their distinct and unique identity, the continuity and consistency of their adoption and use, and the degree of their influence. Second, to determine whether Mexican Americans constitute an ethnic market segment, grocery shopping behavioral patterns are examined. Third, to ascertain whether Mexican Americans represent a substantial ethnic market segment in terms of the number of consumers and the amount of money spent, relevant demographic and socioeconomic characteristics are presented and analyzed. Fourth, the impact of an economically significant ethnic market segment on marketers and marketing institutions is assessed. Due to the nature of this study, emphasis is placed on the collection of primary data, which has been obtained through personal interviews with 115 consumer respondents and eighteen grocery store owners and managers. Secondary data, gathered from reports of the Bureau of the Census, various periodicals, journals, and books, are used to establish cultural, demographic, and socioeconomic trends.
The Poetic Ideal in the Piano Music of Franz Liszt: A Lecture Recital, Together with Three Recitals of Music by Mozart, Beethoven, Schubert, Chopin, Brahms, and Contemporary European and North American Composers: The dissertation consists of four recitals: one chamber music recital, two solo recitals, and one lecture recital. The chamber music program included a trio with the violin and cello performing with the piano. The repertoire of all of the programs was intended to demonstrate a variety of types and styles of piano music from several different historical periods. The lecture recital, "The Poetic Ideal in the Piano Music of Franz Liszt," was an attempt to enter a seldomexplored area of Liszt's musical inspiration. So much has been written about the brilliant and virtuosic compositions which Liszt created to demonstrate his own technical prowess that it is easy to lose sight of the other side of his creative genius. Both as a composer and as an author, Liszt reiterated his belief in the fundamental kinship of music and the other arts. The visual arts of painting and sculpture were included, but he considered the closest relationship to be with literature, and especially with poetry.
A Visual-Aural Self-Instructional Program: In Pitch-Error Detection for Student Choral Conductors: This study seeks to develop and evaluate a program of selfinstructional drill materials for improving the ability of students to detect pitch errors in choral singing. The specific purposes of the study are as follows: (1) To develop and validate a visualaural test for pitch-error detection; (2) to develop a visual-aural, self-instructional program for improving the ability of students to detect pitch errors; and (3) To determine whether the program of self-instructional drill materials modifies the ability to detect pitch errors. In the first phase of this three-phase study, a body of testing materials was assembled, pilot-tested, edited, and judged reliable for use. In Phase II a body of self-instructional, programmed drill materials was assembled, pilot-tested, corrected, and judged ready for evaluation. In Phase III the procedures were as follows: (1) the subjects for whom the program was intended were administered a pretest of their pitch-error detection ability; (2) one group (A) participated in the programmed drill materials developed, while the other group (B) used no programmed materials; (3) both groups were administered a midtest to determine whether there was any change; (4) the latter group (B) participated in the programed drill materials developed, while the first group (A) no longer used the programmed materials; (5) students in both groups were administered a posttest to deterine the effectiveness of the programmed drill materials in developing the ability to detect pitch errors while reading the vocal score.
Shubnikov-de Haas Effect Under Uniaxial Stress: A New Method for Determining Deformation Potentials and Band Structure Information in Semiconductors: The problem with which this investigation is concerned is that of demonstrating the applicability of a particular theory and technique to two materials of different band structure, InSb and HgSe, and in doing so, determining the deformation potentials of these materials. The theory used in this investigation predicts an inversion-asymmetry splitting and an anisotropy of the Fermi surface under uniaxial stress. No previous studies have ever verified the existence of an anisotropy of the Fermi surface of semiconductors under stress. In this work evidence will be given which demonstrates this anisotropy. Although the inversion-asymmetry splitting parameter has been determined for some materials, no value has ever been reported for InSb. The methods presented in this paper allow a value of the splitting parameter to be determined for InSb.
Ludwig van Beethoven: 33 Variations on a Waltz by Diabelli, Op, 120, A Lecture Recital, Together with Three Recitals of Selected Works of J. S. Bach, L. van Beethoven, R. Schumann, F. Chopin, F. Liszt, S. Prokofiev, and E. Granados: The lecture recital was given December 5, 1971. A discussion of Beethoven's 33 Variations on a Waltz by Diabelli, Op. 120 included the circumstances under which the work was composed, analysis of the composition, and controversial opinions on the Variations. The piece was then performed by memory. In addition to the lecture recital three other public recitals were performed. These consisted entirely of solo literature for the piano. The first solo recital was on April 12, 1970, and included works of Bach, Beethoven, and Liszt. Part of the preparation included the writing of program notes of a historical and analytical nature. The second solo recital, on January 31, 1971, consisted entirely of sonatas by Beethoven, Chopin, and Prokofiev. The final solo program, on August 11, 1972, included works by Bach, Schumann, and Granados. All four programs were recorded on magnetic tape and are filed, along with the written version of the lecture material, as a part of the dissertation.
The Effects of an Achievement Motivation Program on the Self-Concepts of Selected Ninth-Grade Students Representing Three Ethnic Groups: The problem with which this investigation was concerned was that of determining the effects that an achievement motivation program had on changing the self-concepts and academic achievement among ninth-grade students in a triethnically mixed junior high school. The subjects for this study were ninth-grade students from a large southwestern city. The experimental program was conducted in a junior high school composed of Anglo, Mexican-American, and Negro students of approximately 30 per cent, 40 per cent, and 30 per cent ratios, respectively. The comparison school was an adjoining area with approximately the same ethnic mixture. In measuring changes in self-concept, the Piers-Harris Children's Self-Concept Scale was used. Teacher-assigned grades converted to numerical equivalents were used in measuring changes in academic achievement. All hypotheses were tested at the .05 level of confidence by using two by three analysis of covariance. All data were entered on computer cards, using computer services of North Texas State University.
Isolation and Characterization of Malic Enzyme from Ascaris suum: A procedure for the isolation of malic enzyme from muscle tissue of the roundworm Ascaris suum is described. The fractionation method yields relatively large quantities of the enzyme,with a specific activity of fifteen moles of malate converted to pyruvate and carbon dioxide per min per mg at 25º. Homogeneity was established with analytical ultracentrifugation, zone electrophoresis, isoelectric focusing, and rechromatography. The molecular weight of the enzyme was 250,000, and it is dissociated under several conditions into four identical monomers of 64,000 daltons. The enzyme exists as a single electrophoretic form and prefers manganous and NAD over other cations and NADP. Ammonium sulfate competes with manganous for the active site and titration with DTNB yields eight thiol groups per mole. Titration of the first four thiol groups is accompanied by a complete loss in enzyme activity. Equilibrium dialysis, product inhibition, and initial velocity studies suggest a rapid-equilibrium random sequential mechanism for the Ascaris suum malic enzyme. The presence of 1.3 binding sites per subunits was determined for L-ma late. Antisera prepared against A. suum malic enzyme reacted to a small extent with the NAD malic enzymes from two free-living nematodes, Panarellus redivivus and Turbatrix aceti. A correlation coefficient of 0.911 was obtained upon comparing the amino acid composition of A. suum and E. coli malic enzymes. Some sequence homology is predicted between these malic enzymes. The physiological interpretation favors the binding of malate initially, with the subsequent addition of NAD to the enzyme.
A Comparison of Certain Factors in Students with and without Financial Aid at Austin College: This study compares certain factors of Austin College financial aid recipients to the same factors in their classmates who received no financial assistance. First, this study attempts to determine whether there are significant differences in selected variables between these two groups. Second, the study seeks to identify the causes for students' withdrawing from the College. Subjects were randomly selected from two groups: (l) 100 subjects receiving financial assistance; and (2) 100 subjects not receiving such assistance. The sources of data for this study were students'. records located in the Educational Advising Center, the Records Office, and the. Counseling Center.
Identification of Glycine as the Factor in Peptone Which Induces Pleomorphism in Azotobacter Vinelandii: The rigid peptidoglycan layer of the cell wall is responsible for maintaining the structural integrity of bacteria. Antibiotics such as penicillin exert their anti-bacterial effect by inhibiting synthesis of peptodoglycan, and enzymes such as lysozyme destroy cell integrity by hydrolyzing specific bonds in the interior of this macromolecule. Defective cells can no longer withstand the high turgor pressure within the cell because they are no longer protected by a rigid wall and tend to become fragile and spherical or irregular in shape. While all bacteria are pleomorphic under certain conditions which do not normally affect other bacteria. This is exemplified by the pleomorphic growth of Azotobacter in nutrient agar or peptone-containing medium. The purpose of this investigation was to study the nature of peptone-induced pleomorphism of Azotobacter. The first phase of study dealt with the effects of poptone on the growth and morphology of A. vinelandii. Many diverse froms were observed in peptone-containing media, but it was shown that all cell types were related to the "fungoid" family of pleomorphic cells. Although Azotobacter failed to accumulate detectable levels of cell-wall precursors in response to glycine treatment, it was shown that glycine acted only on metabolically active cells. In addition, incorporation of glycine into cell wall of Azotobacter was not required for induction of pleomorphism. Methionine and aspartic acid, and to a lesser degree alanine and isoleucine, were found to competitively inhibit glycine toxicity.
Linkage Relationships of Greenbug Resistance in Barley, Hordeum Vulgare L.: The linkage relationship and arm location of the gene for greenbug resistance in the variety Will was determined by using primary trisonomics and tertiary trisomic homozygous translocations. The gene for greenbug resistance was found to be on linkage group 1 by using primary trisonomics. The gene was located on the cetromere segment of the Tl-6a translocation by using a tertiary trismoic homozygous for greenbug resistance. The data further substantiates the feasibility of using trisomics in placing genes on proper linkage groups.
Modern Problems and Practices of Management as Revealed in Selected Contemporary American Novels: This study is an examination of the hypothesis that selected contemporary American novels offer vivid illustrations of modern problems and practices of management as seen in business and industry. Too often, university management courses treat management processes as isolated cases in limited and static settings. Novelists, on the other hand, treat these same processes in a broader context and often deal quite subtly and perceptively with everything from the mammoth corporation to the single proprietorship. Students proposing to become businessmen, therefore, should benefit from this novelistic perspective so frequently overlooked.
The Rise and Fall of the Texas Radicals, 1867-1883: The purpose of this monograph is to study the early Texas Republican party within the framework of well-known political party functions, i.e., to provide political leadership, recruit governmental personnel, generate public policy, and propagate ideology.
The Effect of an In-Service Program Utilizing Bloom's Taxonomy on Teachers' Self-Concepts, Cognitive Level of Test Construction, and Attitudes of Students: The problem of this study was to investigate the effect of an in-service program utilizing Benjamin S. Bloom (Ed.) and others' Taxonomy of Educational Objectives, Handbook I: Cognitive Domain (Bloom's Taxonomy) on (1) the self-concept of experienced secondary English teachers and social studies teachers, (2) the cognitive level of test items on teacher-made examinations, and (3) the attitude changes toward school subjects as rated b students.
