This study of semigroups discusses groups, ideals, relations on semigroups, and relation classes in semigroups. Each topic is covered in some detail; but since this is a general study of semigroups, no topic dominates the paper. The definitions, theorems, and corollaries are supplied by Dr. August Lau, and all proofs are the work of Ms. Bryant.

Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk situations, with males preferred over females across both levels of risk. Results suggested that ratings were based on a stereotype of female inferiority in work efficiency, overriding job sex-orientation as a decision factor.

The problem was to develop a model of thought within the basic structure provided by general or "point-set" topology. To do this, it was necessary to make four basic assumptions. It was assumed that each individual possesses more than the classical five senses and that for each of these there exists a category of sensory data. Also, it was assumed that the Cartesian product of these categories formed a set M of thought elements for each individual, and that certain subsets of M provide support for cogitation. The relation, function, continuous function, and homeomorphism, which are used to relate sets in topology, are discussed as a possible ramification of the model for communication. The global properties of the homeomorphism and continuous function present each as a viable support for strong and meaningful communication between thought spaces of individuals.

After considering Petrouchka's historical and compositional background and the orchestral revision of 1947, this thesis analyzes the composition, dealing specifically with formal, harmonic, and melodic aspects. The study's most important discovery is of a common formal design for all the scenes and the piece as a whole, where the outer thirds of ternary structures are equal in length. The thesis also examines Stravinsky's transcriptional procedures, cataloging and contrasting them with those of the nineteenth century. The solo transcription of Petrouchka is fully discussed in the light of Stravinsky's singular treatment of and writing for the piano. In addition to the recorded performance of Trois Mouvements de Petrouchka, this dissertation includes three tape recordings of selected piano works of J. P. Rameau, L. V. Beethoven, F. Chopin, F. Liszt, C. Franck, A. Scriabin, and G. Crumb.

This interface was bought to perform floating-point arithmetic and for its function capabilities such as SIN, COS, and e^x. My application required an integer truncation function that is not performed by this calculator, so i wrote a small assembly language subroutine to do it. A potentially irritating problem is that the calculator chip does not automatically convert to scientific notation if the numbers become too big to display in floating point. The control program must keep track of the display mode.

A generalization of the independent particle model from nuclear statics to nuclear dynamics is sought. Attention is centered on the average behavior of nuclear dynamics, as opposed to detailed behavior, such as that characteristic of shell effects in nuclear statics. In many situations, all that is needed is a model of dissipation in nuclear dynamics. Completely independent nucleons produce dissipation only when they interact with the surface of a nucleus or when they cross from one nucleus to another. The first possibility manifests itself whenever a nuclear surface deforms. Dissipation is then described by a simple 'wall formula.' The second mechanism for dissipation is relevant whenever two nuclei are moving relative to one another and are in sufficient contact that nucleons can move between them. Another simple expression, the 'window formula,' describes dissipation in this case. Neither of the two formulae has any free parameters.

The purpose of this problem was to investigate the advantages and limitations in the use of blacksmithing techniques combined with the construction techniques of arc welding and the use of power tools to construct large outdoor sculpture. Specific questions will be asked to determine the suitability of this method of working. The questions are: 1. Can blacksmithing techniques be used in the construction of large outdoor sculpture? a. what specific techniques are appropriate? b. Will some techniques be used more than others? 2. Will these techniques be used more than others? 2. Will these techniques take an inordinate amount of time and make them impractical for the artist to use?

Our problem was to produce art in a collaborative manner. Due to the nature of our problem, we proposed to explore specific aspects of collaborative art and answer these questions: 1. in what ways is the co-artist's input beneficial? 2. How are the artist's skills broadened by working with a fellow artist? 3. What is involved in developing a professional working relationship between male and female artist? 4. What understanding of differences in working styles is acquired? 5. What are the differences reflected in each artist's earlier works as compared to the collaborative pieces?

This study involves investigating the combination of delicately cast forms, domed shapes and forged silver into an aesthetic form of jewelry. The specific questions considered were as follows: 1) can the sequential interplay of forms be interrelated from initiation to completion of the study? 2) Can the techniques contrast with one another? 3) Can the scale of the forms be varied? 4) Can the three techniques of construction create body adornment? 5) Can these forms individually or in a combined grouping make a personal statement?

The problem of this study was to determine teachers' perceptions of their school organizational climate, to determine teachers' perceptions of their principal's leadership behavior, and to ascertain the relationships between teachers' perceptions of school organizational climate and principal's leadership behavior. The study had three major purposes. The first was to determine teachers' perceptions of their school organizational climate as measured by the Organizational Climate Description Questionnaire (OCDQ) across selected variables. The second was to determine teachers' perceptions of their principal's leadership behavior as measured by the Leader Behavior Description Questionnaire (LBDQ) across selected variables. The third was to ascertain whether significant relationships existed between teachers' perceptions of school organizational climate and their principal's leadership behavior. Based on the analyses of data, the conclusions could be drawn that: 1. The school organizational climates as perceived by secondary school teachers tended to fall into the closed end of the open-closed climate continuum. It is interesting to note that teachers with more years of teaching experience perceived their school organizational climates as being open. 2. All of the teachers in this study perceived their principal as an effective leader. 3. There was a significant relationship between organizational climate and principal's leadership behavior; however, …

The problem of this study concerns the effects of a parent group counseling procedure and an individual consultation procedure upon (1) the attitude of the parents, (2) the school-related behavior of the children, (3) the academic grades of the children, (4) the peer relations of the children, and (5) self-concept of the children. The results of this investigation indicated no significant differences in procedures for affecting behavior changes on the variables examined. Generally, parent group counseling appeared to generate more pervasive changes affecting multiple behaviors in their children than individual consultation with the parents.

The purpose of this study is to analyze the interaction of (1) the secondary school teacher's knowledge concerning both the problem of adolescent suicide and the potential for teacher intervention and (2) selected demographic variables on the dependent variables of the teacher's attitudes concerning both the problem of adolescent suicide and the potential for teacher intervention in order to develop a data base upon which to examine the prospects for realizing the intervention potential of secondary school teachers in the area of adolescent suicide. Findings indicate that there are significant differences in knowledge concerning the problem of adolescent suicide and the potential for teacher intervention as a function of particular demographics. Similarly, there are significant differences in attitude toward the problem of adolescent suicide and the potential for teacher intervention as a function of particular demographics. Findings further reveal that level of knowledge appears to be a significant contributing factor in the secondary school teacher's attitude as a function of selected demographics. Secondary school teachers appear to possess a low level of knowledge concerning both the problem of adolescent suicide and the potential for teacher intervention, and they exhibit a range of predominantly negative attitudes toward the problem of adolescent …

The purpose of this study was to investigate the personality characteristics associated with accuracy in person perception. The particular personality variables chosen (experience, intelligence, cognitive complexity, psychological mindedness, emotional stability, introversion, and empathic style) for investigation were those previously identified by Gordon Allport as being related to person perception. Both types of person perception (sensitivity to individual differences and sensitivity to group differences) were measured. The major findings of the study were the following: 1. The most capable judges of individual differences, in comparison with the least capable judges, were significantly more likely to have the following psychometric characteristics: higher IQ, more extraverted, more psychologically minded, more cognitively complex/flexible, and more empathic. Experientially, the most competent judges were likely to be older, older in age at first job, and have fewer siblings. In contrast to the least able judges, the most competent ones had resided in more different cities, traveled more, experienced more formal education, and were more likely employed in the helping professions. 2. The best judges of group differences, in comparison with the worst judges, were more likely female, older in age at first job, and higher scorers on Neuroticism. 3. Significant multiple linear regression equations were formed …

The problem of this study was to identify a minimum competency-testing framework for the state of Texas, based upon perceptions of superintendents of schools. Additionally, this study attempted to determine whether relationships existed between school district characteristics and the superintendents' perceptions of minimum competency testing. In summary, eight conclusions were reached with regard to minimum competency testing. Two implications have been presented which would direct the application of a minimum competency framework within the state of Texas. Finally, six recommendations have been made. Five recommendations dealt with additional studies, while one recommendation dealt with the Texas Education Agency's use of results from the five recommended studies.

The purpose of the study was to compare the attitudes of 4-H youths and their parents concerning 4-H competitiveness. The sample was composed of seventy-nine 4-H youths and their parents from three North Texas Counties. The instruments, which consisted of an "Opinionnaire for Parents" and an "Opinionnaire for 4-H'ers," were designed to obtain the 4-H'ers' and parents' attitudes about 4-H competition. The study revealed no significant difference in competitive attitudes between 4-H youths' and their parents' or between younger and older 4-H'ers. 4-H boys were found to have more competitive attitudes than 4-H girls. No significant relationship was found between parents' level of competitiveness and length of 4-H service.

The AKR strain of mice have a genetic trait for spontaneous development of lymphocytic leukemia. In this study, leukemic mice were found to have significantly larger (p<0.01) thymuses and spleens than preleukemic mice. The enlarged leukemic tissues were densely packed with a light staining cell, with a hollow-appearing nucleus. Tissues from preleukemic mice were observed to be infiltrated with a smaller, darker-staining lymphocyte. Fluorescent antibody staining was done on preleukemic and leukemic tissues, using three antisera against murine lymphocyte theta antigen, and an antiserum against murine IgG. Significantly brighter fluorescence, (p <0.05) with theta-specific antisera, was found in leukemic thymuses,spleens, and kidneys than in the same preleukemic tissues. Leukemic tissues had significantly brighter fluorescence (p <0.05) than preleukemic tissues with IgG antiserum.

This thesis looks at child development based on membership in 4-H clubs.

This investigation is to determine the extent of male participation in home economics courses in public schools. Related questionnaires were completed by participants and results tabulated. It was determined that the student's own interest, and their perception of how homemaking will help later are influencing factors for enrollment in homemaking classes. Food preparation, getting along with others, grooming, clothing selection and construction and using new equipment properly are areas of interest to male students. The belief that homemaking is for girls, and the lack of interest in the content and activities of homemaking classes account for the low male participation. Community understanding, friendly attitudes of counselors, a well equipped department, and practical homemaking courses could attract more male participation.

The problem of programming a parallel processor is discussed. Previous methods of programming a parallel processor, analyzing a program for parallel paths, and special language features are discussed. Graph theory is used to define the three basic programming constructs: choice, sequence, repetition. The concept of mechanized programming is expanded to allow for total separation of control and computational sections of a program. A definition of a language is presented which provides for this separation. A method for developing the program graph is discussed. The control graph and data graph are developed separately. The two graphs illustrate control and data predecessor relationships used in determining parallel elements of a program.

Behavioral and cognitive skills training for increasing assertive behavior in college students were compared to an equally credible expectancy-control. One significant multivariate function successfully discriminated between the behavioral and control groups, and between the cognitive and control groups. This function was interpreted as showing enhanced behavioral/cognitive construction competencies in the behavioral and cognitive groups. A second function, though not significant, suggested that the cognitive training resulted in more aggressive behavior.

The novels that compose Colin MacInnes's London trilogy, City_ of Spades, Absolute Beginners, and Mr. Love and Justice, are concerned with British society as it has evolved since World War II. By depicting certain "outsiders," MacInnes illustrates a basic cause of social unrest: the average Britisher is blind to societal changes resulting from the war. Most citizens mistreat the African immigrants, allow their children to be exploited by the few adults who realize the buying power of the postwar youth, and remain oblivious to crime, even among their own police force. Though the novels are social documentaries, they are also valuable as literature. MacInnes's exceptional powers of description, together with his facility with language in general, contribute to the trilogy's merit as a compelling exploration of the human condition.

This study is a detailed textual examination of the word "parallax" in Ulysses. It distinguishes three levels of meaning for the word in the novel. In the first level, parallax functions as a character motif, a detail, first appearing in and conforming to the realistic surface of Bloom's inner monologue, whose meaning is what it tells of his crucial problems of identity. In the second, parallax functions as an integral part of the symbolic complex, lying outside of Bloom's perceptions, surrounding the emblem of crossed keys, symbol of, among other things, paternity and homerule, two major narrative themes. The third level involves parallax as a symbol informing the novel's overriding theme of the writing of Ulysses itself and of the relationship between the novel's representative life and artistic design.

To supplement college introductory statistics instruction, an interactive drill system was developed and implemented on a Hewlett- Packard 2000 timesharing computer. Unlimited practice in basic procedures and algorithms was provided over 38 topics including Chi-square, correlational methods, and one-way analysis of variance. Validation of intermediate computational steps was provided, and more difficult or remedial problems sets were made available. Optional files recorded performance data. Four support programs initialized performance files and generated summary reports. Extensive documentation and a library of reusable subroutines were designed to assist future authors to expand the system. The drill and practice system was made generally available to all university departments and students.

The problem of this investigation was an analysis of selected variables that affected woman's role-concept. Specifically this research was concerned with how a woman's role-concept was influenced by education. This research concluded that the level of education influenced role-concept. Respondents with more than a high school education were very contemporary. Other variable such as marital status, age, parental views, ethnic group, and major seemed to have little effect on role-concept. All groups surveyed were more contemporary than traditional. Further research to determine if all women are becoming contemporary would be meaningful.
