Thin target L-Shell x-ray production cross sections for protons incident on ₆₂Sm and ₇₀Yb in the energy range of 0.3 to 2.4 MeV/amu, alpha particles incident on ₆₂Sm, ₇₀Yb, and ₈₂Pb in the energy range of 0.15 to 4.8 MeV/amu, and lithium ions incident on ₅₈Ce, ₆₀Nd, ₆₂Sm, ₆₆Dy, ₆₇Ho, ₇₀Yb, and ₈₂Pb in the energy range of 0.8 to 4.4 MeV/amu have been measured. The cross section data have been compared to the planewave Born approximation (PWBA) and the PWBA modified to include binding energy and Coulomb deflection effects. The Lα₁,₂ x-ray production cross sections are best represented by the PWBA modified to include both the binding energy and Coulomb deflection effects (PWBA-BC) over the entire incident ion, incident energy, and target ranges studied. However, the Lγ₁ and Lγ₂,₃,₍₆₎ x-ray production cross sections are best represented by the PWBA except at the lower ion energies, where both the PWBA and PWBA-BC are in disagreement with the data. The comparison of Lα₁,₂/Lγ₂,₃,₍₆₎ ratios to theory reveals that the PWBA-BC does not predict the inflection point substantiated by the data, and the agreement between the data and the PWBA-BC becomes worse as the atomic number of the incident ion increases. Comparison …

The problem is to examine the contributions of George S. Benson to Christian education. The study presents data obtained by personal interviews with George Benson and people who have been close to him, excerpts from letters written by former students, teachers, and board members, minutes of the Board of Trustees of Harding College, books, articles, speeches and newspapers.

The problem of this study is the effect of two training models on personnel who teach moderately and severely retarded children. The subjects of this study were sixty-two staff members who work with the moderately and severely retarded pupils in two large metropolitan school systems. Eighteen teachers, eighteen aides, and twenty-six volunteers participated in the study. Two observation instruments administered by trained observers were used as pre- and post-tests to measure the trainees' competencies in applying operant conditioning techniques in both group and one-to-one instructional situations. The purposes of this study were (1) to compare the effectiveness of an experiential model and a didactic model in preparing personnel to deliver cues and reinforcers when working with moderately and severely retarded children; (2) to compare the costs of equipment and supervisory personnel; and (3) to examine the relationship between the trainees' effectiveness of delivering cues and reinforcers to a group of moderately and severely retarded youngsters and the on-task behavior of those students. This report concludes that the trainees' self-evaluation of the training models indicated that they prefer simulated techniques and feedback, which denotes that the Experiential Model may foster certain kinds of incidental learning such as physical mannerisms and visual …

This study compares present policies and procedures for selection of school board members in districts of The Council of Great City Schools with those advocated by board members, professional educators, and representatives of lay organizations. To determine present selection policies for school board members, a questionnaire was sent to the business manager of each participating district. Replies were received from twenty-one of the districts and presented in tables including number and percentage of respondents for each item. To determine opinions of board members, professional educators, and members of lay organizations, a thirty-five-item questionnaire was mailed to 190 board members, 22 school superintendents, 19 college professors, 19 PTA representatives, 22 NAACP representatives, and 11 chamber of commerce representatives. After a return of 200 usable questionnaires, data were presented in separate tables including number of respondents and percentage of respondents. Using the contingency coefficient technique for statistical analysis, null hypotheses were formulated to test relationships between the opinion of respondent groups and selection policies and procedures actually in use. The chi square test was applied to test the relationships, with the .05 level of significance as the criterion. Results were tabulated collectively. Tabulated results indicate that board members should be elected at …

This study was concerned with analyzing selected Texas school administrators in an attempt to locate intrapersonal patterns of (1) values, (2) leadership traits, (3) personality traits, (4) critical thinking ability, (5) perception, and authoritarianism. A second aspect was correlating these profiles with each other. The study had a threefold purpose. The first was to perform a detailed analysis of school administrators to determine selected intrapersonal patterns. The second was to determine possible relationships between these selected profiles. The third was to generate plausible hypotheses for testing the intrapersonal patterns found and for determining the magnitude of any existing relationships. The case studies revealed the uniqueness of each participant in this study. With the possible exception of one individual, certain weaknesses were evident in each of the participants. Canonical correlation and the Pearson correlation of D matrices determined that a relationship existed between many of the profiles. Eight hypotheses were presented at the close of the study as guides for additional research. The results of this study indicated that further research was justified in these particular areas. The results of this study indicated that intrapersonal patterns existed within school administrators and that these patterns or profiles are related. However, the determination …

This study is designed to evaluate the impact of citizen participation in the Goals for Dallas program on the establishment and accomplishment of the goals. Also evaluated are the impact of community leaders on the program, the extent and degree of citizen participation, factors which encouraged and discouraged participation, the impact of local media, and the impact on citizen participants of participating. Twenty-five specific findings are presented, based on the compilation and analysis of inputs received from the citizens and community leaders. Among the most important of these are as follows. 1) The extent of participation on the part of those citizens who did participate in the program was significant. 2) Related to the total adult population of the city, the extent of total citizen participation was small. 3) The program as designed and implemented did have a substantial impact in assisting to overcome citizen apathy in the city. 4) The key items which tended to encourage citizen participation were publicity, civic duty, neighborhood meetings, and personal rewards. 5) The general factors which discouraged citizen participation were general suspicion of the program, general apathy, lack of publicity, and a general suspicion of government. 6) Citizen participation had a significant impact …

Flexible compensation is a new concept in wage and salary administration which permits the employee to select from the various benefits, and cash, a plan tailored to meet his own needs, limited only by his total compensation and those statutory provisions pertaining to his wages. Within recent years, compensation practitioners have been urged in professional journals to adopt flexible compensation as a way to improve their compensation programs in order to attract, hold, and motivate employees. The purpose of this study is twofold. First, the results of this research will provide empirical data on the current status of flexible compensation for nonexempt employees in the United States. Second, the research will contribute toward the development of a set of comprehensive guidelines for implementing flexible compensation programs.

The problem of this study has been an investigation and comparison of the school dropout rates of Mexican American and Anglo Students and their reasons for leaving school in a large metropolitan school district in Texas. The specific purposes were (1) to ascertain the dropout rates of Mexican American and Anglo students within similar socioeconomic status and to compare these rates; (2) to compare the reasons for dropping out of school given by Mexican American and Anglo students; and (3) to delineate the implications for the school district's instructional program and its operation. Based on an analysis of the findings of this study, the following conclusions were formulated: (1) the school district studied is not meeting the needs of Mexican American students, particularly Mexican American females; (2) it can be expected that Mexican American female students are more likely to drop out than are Anglo females; and (3) Mexican American and Anglo dropouts do not believe that there is anyone on the school staff in whom they can confide their decision to drop out.

The purposes were (1) to examine the relationship of four motivational characteristics, as measured by the Merritt College Motivation Inventory (MCMI), to final introductory psychology grades in the two methods of instruction, and (2) to determine the usefulness of the MCMI as a tool for guiding students into open circuit television and on-campus traditional introductory psychology courses. The following research questions were formulated: (1) Can a prediction model using four motivational scales (Intrinsic, Self-Enhancement, Per son-Orientation, and Goal-Deficiency as measured by the MCMI) be developed which will adequately predict achievement in open-circuit television and on-campus traditional introductory psychology courses? (2) Can a prediction model using three of less of the four MCMI scales be developed which will adequately predict achievement in open-circuit television and on-campus traditional introductory psychology courses? (3) Of the four MCMI scales, which one or combination will be applicable in counseling students into open circuit television and on-campus traditional introductory psychology courses? All four hypotheses were confirmed. However, the four motivational characteristics as measured by the MCMI may not adequately predict achievement for the on-campus or telecourse students, The prediction efficiency of the Full and Restricted Models for both groups left significant proportions (81.41 per cent or …

The problem of this study is the development of a model curriculum for high school metallurgy students. The study was made at the Skyline Career Development Center of the Dallas Independent School District, Dallas, Texas. The study has three purposes. In addition to providing a model curriculum for high school metallurgy students, a second purpose is to describe the developmental processes by which the curriculum was derived. The third purpose is the evaluation of the basis of the content of the model curriculum. It was found that of the 76 concept-relationships stated, 64 were true as originally written according to the established rating criteria. It was also found that 64 of the 76 concept relationships stated were appropriate for understanding by high school students, although the two lists of 64 concepts were not identical. The unapproved concept statements were deleted or rewritten according to the established criteria. Only one of the 33 skills listed received a low rating. It was further found from a report of the metallurgy instructor that the 21 high school students in the metallurgy program had attempted a cumulative total of 374 of the 33 behavioral objectives in the curriculum and had accomplished a total of …

The purposes of this study were (1) to determine whether the mean gains on achievement scores in reading and mathematics for bused students in grades four and five after one year in integrated schools is greater than the mean gain in reading and mathematics achievement scores for similar non-bused students in segregated schools; (2) to determine whether school attendance for bused students is greater than attendance for similar non-bused students; and (3) to determine if attitude toward school, academic self-concept, and general self-concept among groups of subjects are different. The analysis and interpretation of data yielded the following conclusions. 1. The elements associated with increased achievement in reading for fourth-grade minority students are not likely to be positively facilitated by increasing the majority-minority ratio by busing. 2. The elements associated with increased achievement in reading for minority fifth-grade students may be enhanced by busing for racial balance. 3. The elements associated with increased achievement in mathematics for minority fourth-grade students may be enhanced by busing for racial balance. 4. The elements associated with increased achievement in mathematics for minority students are not likely to be facilitated by increasing the majority-minority ratio. 5. The busing of minority students out of their …

This study concerned the paucity of group counseling procedures designed specifically for use with parents of handicapped children. Purposes of the study were- (1) design of an affective-cognitive group counseling procedure, (2) investigation of affective-cognitive group counseling procedural effects with parents of handicapped children, (3) determination of procedural effects in a. changing the intra- and interpersonal attitudes of parents, b. increasing parents' knowledge of Positive Behavior Management, and (4) determining comparative procedure effects. Four research hypotheses related to the efficacy of the affective-cognitive group counseling procedure were formulated and tested at the .05 level of confidence. Statistical analysis of data indicated that parents participating in the affective-cognitive group counseling procedure did not achieve significantly higher posttest mean scores on the Acceptance of Self and Others test or in the five areas of the Parent Attitude Survey Scale than did parents participating in the affective, cognitive, or control group. Data did reveal that parents participating in the cognitive group did achieve significantly higher adjusted posttest mean scores on the Positive Behavior Management Assessment than did parents participating in the affective-cognitive, affective, or control group. Data also indicated that parents in the affective-cognitive group did not obtain greater mean scores on goal-attainment …

The problem of this study was to ascertain the role and status of the specialist in human relations in the desegregation of selected public schools in Texas. Its purpose was to review human relations literature in order to compile a list of representative criteria for human relations programs in industry and to describe the human relations programs and roles of the directors in selected schools. An analysis of available information indicated that industrial organizations have given more attention to human relations programs than have the educational institutions of this country, although their problems have been similar. It was in the workshops of the factories, rather than in the classrooms of America, that social scientists developed human relations skills and techniques. The social issue of desegregation of the races has been a battle often fought on public school campuses. These racial confrontations, coupled with conflicts spawned by the rigidity of traditional schools, have signaled the urgent call for human relations programs to alleviate human problems. The background study included a review of relevant literature, interviews with public school officials, and discussions with state and regional educational administrators. The survey technique was used to collect data for the study. Personal interviews were …

The purposes of this study were (1) to identify the major goals of independent senior colleges and universities in Texas, (2) to survey the opinions of persons in positions of leadership in independent senior colleges and universities in Texas with respect to existing and preferred goals, (2) to determine if there are significant differences of opinion among these persons, and (4) to develop projections of the probably priorities for goals of independent senior colleges and universities in Texas, based upon the expressed opinions of these persons in positions of leadership. According to the opinions of institutional leaders, the major goals pertain to quality faculty and academic freedom, to areas which are directly related to the personal, social, and intellectual development of students, and to the continuance of quality academic programs. Based on the opinions of these groups, plans and decisions in independent higher education in Texas over the next decade will be influenced more by financial matters than by any other factor. Other goals which will be important include continued development of strong academic programs, spiritual and moral growth of students, stabilization of enrollment, and development and retention of quality faculty.

The first purpose of this study was to provide an overview of the educational policy-making role of the United States Office of Education, 1963-1969. A historical overview of significant events before 1960 was provided to aid in understanding that federal concern for and financial aid to education is not a recent concept. The second purpose of this study was to examine the policy-making roles of the Commissioner of Education during the Lyndon B. Johnson presidency.

The purpose of this study is threefold: (1) to analyze grievance arbitration cases involving racial discrimination which occurred from 1964 to 1975; (2) to recommend guidelines suitable to the use of grievance arbitration in the settlement of racial-discrimination disputes; and (3) to predict trends regarding future utilization of grievance arbitration as a forum through which racial-discrimination victims can seek redress.

The purpose of the study was to develop a theory and model for motivity of consciousness which would constitute a system of thought motivity. The major premises of currently prominent theories of motivation, including psychoanalysis, learning theory, self-actualization theory, and topological psychology, were surveyed. Related materials in the area of psychic research and energy systems related to mental function were surveyed. The primary activities and processes called thought motivity were identified along with some of the major forces on the individual. From the identified forces and processes a theory of thought motivity was developed. A conceptual model for motivity of consciousness based upon the theory was designed. The theory and the model considered together constituted the system of thought motivity. Brain processes and biological actions of the human organism were proposed to have a functional, interdependent relationship. Thought was considered to be a functional of brain processes. It was postulated that a certain minimal level of biological actions were continuous in the living organism; therefore, thought was continuous. It was postulated that at any given point in time and space a universe of events would exist which was capable of producing outcomes in the brain. Of that universe of events …

The problem of this study was to investigate the relationship between parent and pre-adolescent adjustment within intact families, short-term divorced families, and long-term divorced families, and to compare the adjustments of parents from intact families, short-term divorced families, and long-term divorced families.

This study is an investigation of the subject matter of eighty Italian cassone paintings of the fifteenth century now located in the United States and answers a four-part question: (1) What were the major themes pictured on cassoni panels during the Quattrocento? (2) Were the themes of cassoni in Quattrocento Italy predominantly of a religious or secular nature? (3) If secular subject matter was dominant in cassone painting, was this a reflection of the newly founded tastes of aristocratic, wealthy and middle classes? (4) Did cassoni mirror the way these classes viewed themselves and the place occupied by women in society?

The problem of this study was to assess sociometric status and selected variables relative to the selection and training of counselors. The relationship of sociometric status and six variables were investigated. The six variables were counselor evaluation rating, grade earned in a graduate course in group counseling, GRE score, chronological age, gender, and possibility of modification of preliminary perceptions of social choice by a graduate level course in group counseling. It was concluded that sociometrically highly chosen counselors-in-training tend to receive high counselor evaluation ratings. Those individuals who received high grades in a group counseling course that is part lecture and part experiential (participation in a laboratory group) also tended to receive high sociometric scores. This was not true for the students enrolled in a graduate admission seminar course that was all lecture. The sociometric status of counselors-in-training does not appear to be related to GRE scores, age, or gender. The mean sociometric status score of the group studied was not significantly modified by a graduate course in group counseling.

The problem of this study was the analysis of the pectoralis major during six antigravity exercises using electromyographc techniques. Thirty male subjects were used for the investigation from physical education classes at North Texas State University during the spring of 1976.

In accordance with theories of Carmichael (19), Lecky (41), and Rogers (55), which suggest that adolescence is a time of redefining conceptions about one's self in relation to values, groups, and institutions in one's environment, the following hypotheses were proposed to be investigated in this study: 1. The difference between mothers' and fathers' self-concept scores is nonsignificant. 2. Parents have higher self-concepts than their children. 3. Parents of children with high self-concepts will differ significantly from parents of children with low self-concepts with respect to their values.

This study is concerned with an analysis of twenty paintings by Western European artists from the thirty-five-item segment of the Anthony Denney Collection on permanent loan to the Dallas Museum of Fine Arts. The paintings were considered separately in a two phase visual and verbal analysis accompanied by visual diagrams. Phase one described the primary visual qualities of each painting through examination of the art elements and principles. Phase two was a verbal description of each painting. The purpose of this investigation is to provide an analysis format suitable for abstract and non-objective works of art.
