Two-proton pickup studies with the (6Li,8B) reaction
The (/sup 6/Li,/sup 8/B) reaction has been investigated on targets of /sup 26/Mg, /sup 24/Mg, /sup 16/O, /sup 13/C, /sup 12/C, /sup 11/B, /sup 10/B, and /sup 9/Be at a bombarding energy of 80.0 MeV, and on targets of /sup 16/O, /sup 12/C, /sup 9/Be, /sup 7/Li, and /sup 6/Li at a bombarding energy of 93.3 MeV. Only levels consistent with direct, single-step two-proton pickup reaction mechanisms were observed to be strongly populated. On T/sub z/ = 0 targets, the spectroscopic selectivity of this reaction resembles that of the analogous (p,t) reaction. Additionally, these data demonstrate the dominance of spatially symmetric transfer of the two protons. On T/sub z/ greater than 0 targets the (/sup 6/Li,/sup 8/B) reaction was employed to locate two previously unreported levels (at 7.47 +- 0.05 MeV and 8.86 +- 0.07 MeV) in the T/sub z/ = 2 nuclide /sup 24/Ne and to establish the low-lying 1p-shell states in the T/sub z/ = /sup 3///sub 2/ nuclei /sup 11/Be, /sup 9/Li, and /sup 7/He. However, no evidence was seen for any narrow levels in the T/sub z/ = /sup 3///sub 2/ nuclide /sup 5/H nor for any narrow excited states in /sup 7/He. The angular distributions …

Adapting Reproduction Knowledge and Photomechanical Techniques to Serigraphy for Non-Commercial Purposes
This problem is involved with attempting to answer two basic questions: (a) Can I, a commercial artist, expand and develop as an artist through screen printing and make valid aesthetic statements unrelated to client and/or product? and (b) Can knowledge of reproduction methods and photo-mechanical techniques be successfully utilized in screen printing for non-commercial purposes? Extensive notes in the form of a journal were maintained as work on the project progressed. These notes, combined with the completed prints, were the sources of data for this paper.

An Analysis of Selected Contents Related to the Usage of Art and Aesthetic in Two Texts in Art Education
Because the terms art and aesthetic are often ambiguously used, the purpose of this study was to develop a method of analyzing and clarifying their usage in written texts. Chapter I includes hypotheses and assumptions of this study. The first hypothesis was that it is possible to develop a systematic, objective, and replicable method of analyzing and clarifying the usage of art and aesthetic in art education texts. The second hypothesis is that, as a result of this analysis, it is possible to compare the usage of art and aesthetic in one text with the usage of these same terms in another. The two texts chosen as sources of data were Becoming Human Through Art by Edmund Burke Feldman and Emphasis; Art by Frank Wachowiak and Theodore Ramsey. The assumptions upon which this analysis was based are (a) that frequency of mention indicates author emphasis, and (b) that, based on analysis which indicates emphasis, summary definition of an author's teaching beliefs regarding art and aesthetic would be possible. Although both hypotheses are accepted, limitations of the method result from the subjectivity which existed in the selection of variables, the inference of contextual meaning which determined placement of variables in categories, …

An Analysis of the Attitudes Regarding Job Satisfaction Held by Negro Professors and White Professors in Selected Institutions of Higher Education Desegregated Since 1954
The purpose of this study was to determine whether participation in an instructional module on procedures for individualizing instruction produced results different from those produced by a traditional education approach with respect to the performance, attitude, self-concept, and dogmatism of special education student teachers. The findings were (1) there was no significant difference between the experimental and comparison groups with respect to teaching-performance; (2) the experimental group's mean self-evaluation teaching-performance score was significantly different in a negative direction than the mean self-evaluation teaching-performance score for the comparison group; (3) both groups had positive correlations between teaching-performance scores and self-evaluation scores, but the experimental group had a significantly higher correlation; (4) there was no significant difference between the experimental group and the comparison group with respect to change in attitudes; (5) there was no significant difference between the experimental and comparison groups with respect to the degree of change in self-concept, and (6) there was no significant difference between the experimental and comparison groups with respect to degree of change in dogmatism.

Ann Radcliffe: A Study in Popular Literary Taste
The purpose of this paper is to determine why Mrs. Radcliffe's gothic novels were popular with contemporary readers. Sources include reviews from eighteenth century periodicals, essays of early nineteenth century critics such as William Hazlitt and studies of her work by twentieth century critics. The thesis is organized in four chapters each of which discusses one aspect of her work which particularly pleased her contemporary reviewers and critics: her invention, her attitude toward superstition, her use of poetic justice, and her outlook on nature. These aspects of her work alone did not secure for her the popularity she enjoyed, but, when combined with her ability to create suspense, helped her become one of the most popular writers of her era.

Aspects of the Thermal Ecology of Largemouth Bass (Micropterus salmoides) in North Central Texas
The coefficient of body temperature change (K) ranged from -0.53 to -0.072 for bass weighing 73-1440 g. The double log regression of K on weight was similar to that reported for other poikilotherms (slope = -0.57; R = 0.93). Fingerling bass were eurythermal, being capable of surviving instantaneous temperature changes over a 20 C range at acclimation temperatures of 15, 25 and 30 C and over a 15 C range at acclimation temperatures of 20 and 35 C. Preferred temperatures for adult bass measured in the laboratory ranged from 27-32 C with no relationship to day or night. The overall mean preferred temperature was 29 C. The laboratory determined preferred temperatures were supported by limited field determined body temperatures taken in a vertical temperature gradient near the discharge of a power plant effluent. Routine metabolic rates of bass from a heated reservoir and a nearby hatchery were similar from 10-30 C in summer and winter. The weight exponent (0.77) and Q^gS (1*6-2.9) were similar to those published for more northern bass populations; however, the Texas bass had lower metabolic rates than those published for the northern populations. Bass exposed to rapid temperature increase (0.2 C/min) from 25-30 C increased their …

Auditory Function in Patients with Sickle Cell Anemia
This study investigated the incidence of peripheral hearing loss in sickle cell anemia and the possibility of central auditory nervous system involvement. Nine Black subjects with sickle cell disease and nine with normal hemoglobin were administered an auditory test battery. There appeared to be no correlation between number of crisis episodes, duration of symptoms, severity of symptoms, and audiologic manifestations. Acoustic reflex testing suggested the possibility of "aired neural function in the sickle cell group. Whether impaired function was due to peripheral VIIIth nerve or to central brain stem involvement could not be determined. Results of the central auditory test battery suggested the possibility of impaired or reduced central auditory function in subjects with sickle cell anemia.

The British Withdrawal from the Arabian Gulf and Its Regional Political Consequences in the Gulf
This study has a twofold purpose: to demonstrate the causes of and various responses (British domestic, Iranian, Arabian, American, and Soviet) to the British decision to withdraw and to illustrate the regional political consequences of that withdrawal. The British Labour Government decision resulted primarily from an economic crisis. The various responses to the decision seem to have been motivated by national self-interest. Some of the Gulf states-- Iran, Iraq, Saudi Arabia, and Kuwait--predicted that the consequences of the withdrawal would be desirable while others--Bahrain, Qatar, and the United Arab Emirates-- predicted that the consequences would not be beneficial. In some ways, both sides were correct in their predictions.

Charlotte Perkins Gilman: A Humanist Approach to Feminism
Charlotte Perkins Gilman (1860-1935), writer and lecturer, provided philosophical guidance to the feminist movement of the late nineteenth and early twentieth centuries, During a career spanning the years 1890 to 1935 she published eleven books, wrote articles for popular magazines, and lectured throughout the United States and Europe. Between 1909 and 1916 she wrote, edited, and published a monthly magazine entitled The Forerunner. Gilman's efforts dealt primarily with the status of women, but she described herself as a humanist rather than a feminist. She explained that her interest in women arose from a concern that, as one-half of humanity, their restricted role in society retarded human progress. Thus, Gilman's contribution to feminism must be viewed within the context of her humanist philosophy. Gilman's contribution to feminism lies in her diagnosis of woman's predicament as ideological rather than political and, hence, subject to self-resolution. The uniqueness of Gilman's approach is in the autonomous nature of her solution: Woman, through the full use of her human powers, could achieve the equality that decades of political agitation had failed to accomplish. The rationale for this dissertation lies in the premise that Gilman's humanist approach to feminism made a significant contribution in her own …

Comparative Chemistry of Thermally Stressed North Lake and Its Water Source, Elm Fork Trinity River
To better understand abiotic dynamics in Southern reservoirs receiving heated effluents, water was analyzed before and after impoundment in 330 ha North Lake. Macronutrients, metals, and chlorinated hydrocarbons were measured. Concentrations of nutrients and metals in sediments were quantified in this 2 yr study. River water prior to impoundment contained 16 times more total phosphorus, and supported 23 times more Selenastrum capricornutum cells in an algal assay than reservoir water. The reservoir has essentially no drainage and since evaporation is high, the concentrations of many dissolved solids have increased since the reservoir was filled in 1958. North Lake is now phosphorus limited. Apparently altered chemical equilibria have caused precipitation or adsorption of phosphorus with calcium and iron.

A Comparison of a Transpersonal Psychology Technique and a Lecture-Oriented Technique of Teaching General Education Mathematics
The problem of this study was a comparison of two techniques of teaching general education mathematics: a transpersonal psychology technique and a lecture-oriented technique. The purposes of the study were to determine the relative effectiveness of a transpersonal psychology technique and a lecture-oriented technique in promoting an understanding of the structure of the real number system, in the development of students' attitudes toward mathematics, and in the retention of knowledge of the real number system. The results of this study were generally inconclusive. It seems necessary that more research be done in the application of relaxation procedures and guided fantasy journeys to the teaching of mathematics before definite conclusions are drawn concerning the effectiveness of the techniques. The paper describing the experimental study consists of five chapters, five appendixes, and a general bibliography. The first chapter is introductory and presents the problem, purposes, hypotheses, and other introductory materials. The second chapter consists of a synthesis of research done in the area of man's two-hemisphere brain and a synthesis of material on the informal applications of the transpersonal teaching technique. Chapters four and five describe the collection of data and the analysis of the data. The fifth chapter presents findings, conclusions, …

A Comparison of Job Corps Graduates and Non-Graduates with Respect to Selected Academic and Psychological Variables
The problem with which this investigation is concerned is that of determining the academic as well as psychological differences between the McKinney Texas Job Corps graduates and non-graduates. The purpose of the study is to gain knowledge that will be useful in the guidance of Job Corps students. Nine hypotheses were formulated to investigate the relationship between academic achievement and certain selected academic and psychological variables. It was concluded that significant personality differences do exist among the McKinney Job Corps graduates and non-graduates. Chronological age is a significant variable with respect to success at the Job Corps Center. Academic variables are not useful indicators of success at the Job Corps training program.

Comparison of the Personalities of Non-Injured and Injured Female Athletes in Intercollegiate Competition
This study was designed to determine if differences exist between the personalities of injured and non-injured athletes, injured and non-injured athletes in individual sports, and injured and non-injured athletes in team sports. Subjects were forty-three female athletes selected from six intercollegiate teams. The test instrument was the Cattell Sixteen Personality Factor Questionnaire. Data were analyzed by the two-way analysis of variance. Alpha was .05. Conclusions of the investigation were that the personality of injured athletes does not differ from the personality of non-injured athletes, that non-injured athletes in individual sports are more self-assured than non-injured athletes in team sports, and that the personality of athletes in team sports does not differ from the personality of athletes in individual sports.

Counselor Perception of Selected Client Attributes and the Relationship of These Perceptions to the Counselors' Own Possession of These Same Attributes
The purposes of this study were to determine the accuracy of counselor perception of client attributes after an initial interview, to determine the relationship that exists between counselors' perceptions of a client's attributes and the counselors' possession of the same attributes, to determine the accuracy of counselor self-perception and to determine whether there were significant differences between counselors who are accurate perceivers and counselors who are inaccurate perceivers of client attributes. The findings pointed to the need for more training in the area of person perception in the master's level counseling program. This need is two-fold. First, counselors-intraining need to become more aware of their own personality, needs and emotions and how these might affect what they see in their clients. Second, counselors-in-training need to become more aware of personality attributes, needs, and emotions in their clients.

The Development of an Art I Curriculum Guide for the Mesquite Independent School District
This study reports on the development of a curriculum guide to insure some degree of experience uniformity in the first art course available to students in high schools in Mesquite, Texas. Current general education and art education literature as well as curriculum guides from American schools provided the behaviorally oriented framework and objectives, content, and teaching strategies. The guide reflects a balance between the ideal and the real physical environment in which the guide will be implemented. Conclusions include the concepts that teacher education in using behavioral objectives is necessary, that a behaviorally oriented guide will work in Mesquite high schools, that behavioral objectives will facilitate evaluation, and that the trend toward tri-part subject content will increase in art curricula.

The Development of the Art Song in the United States: 1890-1920 a Lecture Recital, Together with Three Recitals of Selected Works of J. S. Bach, W. A. Mozart, J. Brahms, M. Moussorgsky, J. Ibert, R. Strauss, C. Floyd, and Others
The lecture recital was given on August 5, 1976. Subsequent to a presentation of some pertinent background material, diverse influences on the compositional styles of five representative composers of the period were discussed. Nine songs by Edward MacDowell, Charles Loeffler, Sidney Homer, John Alden Carpenter, and Charles Griffes were interspersed as musical illustrations. In addition to the lecture recital, three other public recitals were performed. The first solo recital was presented on July 26, 1973, and included works by Johann Sebastian Bach, Richard Strauss, and Wolfgang Fortner. The second solo recital, given on December 3, 1973, was comprised of works by Wolfgang Amadeus Mozart, Jacques Ibert, Arrigo Boito, and Modeste Moussorgsky. The third solo recital (with Miss Jo Ann Pickens assisting), was presented on June 26, 1974, and included works by Thomas Arne, Richard Wagner, Johannes Brahms, Benjamin Godard, Giuseppe Verdi, and Carlisle Floyd.

Differential Life History Factors Among Incarcerated Female Offenders
This study was designed to be the first step in an empirical investigation of the female offender, using biographical information. It Is the goal of the research to eventually be able to predict probable criminal activity among women. The most readily delineated group for study was female prisoners. The purpose of the study was to determine if factor clusters could be produced which were representative of women in prison. Specific objectives were to organize descriptive biographical information of incarcerated women and to correlate bio-data results with important current and post-incarceration events. This study makes it clear that merely labeling behavior as criminal—connoting a deviant class of behavior—is highly inexact in identifying it. The female offender cannot as yet be defined in the same way as a person suffering from depression, hypochondriasis, or schizophrenia—that is, by distinctive response groupings. While this study made many inroads, generating descriptive factors and significant behavioral/life-history correlates, incarcerated female offenders as a class cannot as yet be identified by responses that make up a valid category of behavior.

Diphenyloxazole Metabolism by Aryl Hydrocarbon Hydroxylase
2,5-Diphenyloxazole (PPO) was tested as a potential alternate inducer for the aryl hydrocarbon hydroxylase (AHH) system. Its apparent lack. of carcinogenicity and toxicity provide a possible system for investigation of enzyme systems related to chemical carcinogenesis without exposure of the researcher to potent carcinogenic compounds. These studies found PPO to be an inducer of AHH in cultured human lymphocytes. When PPO was utilized as a substrate for the AHH assay system, the major metabolites produced were strongly fluorescent. A simple fluorometric assay was developed which employed PPO as the substrate and which measured constitutive activity more efficiently than similar assays using benzo(a)pyrene as the substrate. Quantitation of both basal and induced lymphocyte AHH metabolism of PPO may be applicable to human population studies and may provide a tool to determine possible genetic variables with respect to carcinogen metabolism related to cancer risk.

DNA-DNA Hybridization of Methane Oxidizing Bacteria
Bacteria classified in the family Methylomonadaceae must derive their carbon from one-carbon compounds. They are characterized by the possession of internal membranes of two types. Type I membranes are layered and fill the middle of the cells while type II membranes form concentric layers around the periphery of the cells. Also, there are two metabolic pathways by which the methylobacteria assimilate one-carbon compounds. Further evidence of this dichotomy was sought by DNA-DNA saturation hybridization of DNAs from both types of methylobacteria. Very low DNA-DNA homology was seen between types I and II or within the types. It was not possible, therefore, to correlate the degree of genetic relatedness with either the nature of the internal membranes or the pathway of carbon assimilation.
