Measurements of the target thickness dependence of the target x-ray production yield for incident fast heavy ions are reported for thin solid Cu targets as a function of both incident projectile atomic number and energy. The incident ions were F, Al, Si, S, and CI. The charge state of the incident ions was varied in each case to study the target x-ray production for projectiles which had an initial charge state, q, of q = Z₁, q = Z₁ - 1, and q < Z₁ - 1 for F, Al, Si, and S ions and q = Z₁ - 1 and q < Z₁ - 1 for C1 ions. The target thicknesses ranged from 2 to 183 ug/cm². In each case the Cu K x-ray yield exhibits a complex exponential dependence on target thickness. A two-component model which includes contributions to the target x-ray production due to ions with 0 and 1 K vacancies and a three-component model which includes contributions due to ions with 0, 1, and 2 K vacancies are developed to describe the observed target K x-ray yields. The two-component model for the C1 data and the three-component model for the F, Al, Si, S, and C1 …

The purpose of this study was to investigate the effects of aspirational and dissociative reference group influence on consumer behavior. There are two ways in which behavior is influenced by reference groups. First, reference groups influence aspiration levels and therefore play a major role in producing satisfaction or frustration. Second, reference groups influence kinds of behavior, i.e., they establish approved patterns of behavior.

The purpose of this study was to determine whether similarities exist in the perceptions of the roles of academic deans in community colleges. This study attempted to determine whether role expectations and perceptions reflected separate and distinct relationships, or if administrative patterns reflected an overlapping of responsibilities.

The purposes of the study were (1) to assess the validity and reliability of Values for Helpers, (2) to determine whether the test would be a usable instrument for analysis of value systems of mental health professionals, (3) to provide information on possible utilization of the test as a measurement tool for assessing the quality of relationship skills of helpers, and (4) to provide information of a heuristic nature for future research with Values for Helpers. To accomplish these purposes, the following questions were examined. 1. What are the relationships between the scales of the Allport-Vernon-Lindzey Study of Values and Values for Helpers? 2. What are the relationships between the scales of the Personal Orientation Inventory and Values for Helpers? 3. What are the relationships between the total scores on Myrick and Kelly's Counselor Evaluation Rating Scale and the scales of Values for Helpers? Conclusions based on the results suggested that (1) there was acceptable reliability for Values for Helpers, (2) the tribalistic and conformist scales of Values for Helpers demonstrated negative convergent validity with the scales of the Personal Orientation Inventory, (3) the existential scale of Values for Helpers demonstrated positive convergent validity with the scales of the Personal …

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 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 …

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 this study was to use a cross categorical scoring method for sociometric data focusing upon those individuals who have made the selections. A cross category selection was defined as choosing an individual on a sociometric instrument who was not within one's own classification. The classifications used for this study were sex, race, and perceived achievement level. A cross category score was obtained by summing the number of cross category selections. The conclusions below are the result of this study. Cross categorical scoring provides a useful method of scoring sociometric data. This method successfully focuses on those individuals who make sociometric choices rather than those who receive them. Each category utilized provides a unique contribution. The categories used in this study were sex, race, and achievement level. These are, however, only reflective of any number of variables which could be used. The categories must be chosen to reflect the needs of the particular study in which they are included. Multiple linear regression analysis can be used in order to provide the researcher with enough scope to handle numerous nominal and ordinal independent variables simultaneously. The sociometric criterion or question does make a difference in the results on cross …

This study dealt with the perception of dissonance by male, female, freshman and senior music majors. A test was devised which would show that there is a significant difference in dissonance perception between freshman versus senior and male versus female music majors, utilizing specific excerpts from the musical repertoire. Test item analysis was also employed to determine if a significant difference occurs in each excerpt. It was found that certain excerpts show a significant difference while the means of the combined groups do not. This phenomenon was because of relative uncertainty in response between dissonant ("four") and extremely dissonant ("five") excerpts. The conclusions of the study based upon the hypotheses were the following: 1. Four years in a university environment makes a significant difference in a music major's perception of dissonant sounds in music. 2. The sex of the music major causes no significant difference in the perception of dissonance. Male responses were consistent with female responses within the same class.

The problem with which this investigation was concerned was that of evaluating the Mid-Management concept of cooperative education at Tarrant County Junior College's South Campus. Evaluative data regarding the various parts of the Mid-Management program were obtained from current students, graduates, and employers, through use of primary source questionnaires and interviews. This study leads to the conclusion that promotional opportunities for students and especially graduates have been enhanced by more than 15 percent and, that a significant number of students and graduates have experienced an improvement in self-image and an increase in self-confidence. It is concluded further, that employers have perceived an increase in their Mid-Management employees' understanding of the manager's job and in their performance on the job, and that employers positively endorse the job-related-project approach of cooperative education. Earnings of both current students and graduates increased substantially after participation in the program; some of these improvements can probably be attributed to the program itself while others were due to inflation, tenure on the job, and other factors.

The purpose of this study was to identify and describe the purposes, plans, activities, and programs of the National Education Association that focused upon instruction. To carry out this purpose, guideline questions were developed. Answers to the questions were sought through leads obtained from a study of the volumes of Addresses and Proceedings for the years since the first NTA meeting in 1857 through the 1976 NEA Convention and editions of the NEA Handbook from the first in 1945 through the 1976 edition. Findings were presented in a six-chapter historical-descriptive narrative. Although interest in instruction is not an exclusive concern held only by professional associations, the findings of this study do suggest that instruction has been a fortunate focus for the NEA in two respects. First, the times of NEA's more obvious emphasis on instruction have been relatively free of criticism of Association activity. Secondly, emphasis on instruction has emerged as a thread to unify the National Education Association with diverse organizations and with classic human institutions--the home, the church, the school, and governmental agencies--throughout the world.
