Characteristic L-shell x rays of the five rare earths Pr, Sm, Eu, Gd, and Dy were studied in this work. The x rays were produced by ionization from 0.3 to 2.0 MeV protons from the 2.0 MV Van de Graaff at North Texas State University. Total L-shell ionization and x-ray production cross sections were measured for Sm and compared to the BEA, CBEA and PWBA theories. Total L-shell ionization cross sections were measured for Pr, Eu, Gd, and Dy and compared to the BEA, CBEA, and PWBA. The CBEA and PWBA fit the samarium data well for both ionization and x-ray production cross sections. The BEA was generally 40 per cent lower than the data. The CBEA and the PWBA also fit the ionization cross section data for Pr, Eu, Gd and Dy, while the BEA was generally 40 per cent lower than the data.

This working bibliography of 835 publications on the art of drawing is presented in five categories: Educational and Psychological, Historical, "How-to," Technical, and Techniques of Teaching Drawing. The latter category is annotated, offering a synthesis of the areas of art education and drawing. This bibliography is designed for scholars, artists, and teachers as well as students of the many facets of drawing.

The purpose of this study is to set forth the history of radio in Nigeria. Chapters explore the history of Nigeria, the history of Nigerian radio, and the present structure of Nigerian radio. In a final chapter, specific historical factors are isolated that have made Nigerian radio what it is today. The study concludes that the present structure of Nigerian radio is a direct product of the peculiar history of Nigeria as a former British Colony. Little can be done to solve the problems of Nigerian radio unless the problems of Nigeria itself are first solved.

This study describes certain characteristics of mature women students in a community college in a large metropolitan district. Three standardized instruments gathered data on self-actualization, self concept, and locus of control. A questionnaire collected demographic and education data as well as information on attitudes, motivations, problems encountered, and suggestions. The women perceived attitudes of their families as positive toward their education. They were motivated by desires to gain knowledge, get degrees, obtain promotions, and improve themselves. They cited themselves, long-time ambition, friends, and husbands as influential in motivating them to attend college. They selected this community college because of its convenience. The majority were married, had children, and were of the middle to upper-middle class. Over half were employed. Their average age was thirty-seven. They were active outside the home, although continuing to perform most traditionally feminine home responsibilities. The majority were part-time students, classified as freshmen. Education, business, nursing, accounting, and psychology were popular majors. Over half planned to obtain bachelor's degrees. Most felt they encountered no problems in pursuing their education; lack of sufficient time was their major complaint. Most were pleased with their community-college experience. their suggestions included special counseling, flexible class schedules, a club for mature …

The purpose of this study was to observe the differences in English achievement, critical-thinking ability, and attitude toward subject attributable to two scheduling approaches -- "Concurrent" and "Intensive"--in the teaching of first-semester freshman English composition to community college students. Further, the study was initiated in order to provide factual information as a basis for administrative and instructional judgments affecting future planning for accelerated scheduling at the experimental institution. Two classes of first-semester freshman English composition, meeting three hours weekly for fifteen weeks, comprised the control group (Concurrent); two classes of first-semester freshman English composition, meeting nine hours weekly for five weeks, comprised the experimental group (Intensive). The same form of three criterion instruments was administered to both groups before and after the experimental treatment. The instruments were the Cooperative English Expression Test, the Watson-Glaser Critical Thinking Appraisal, and the Purdue Attitude Scale, Part A -- Attitude Toward Any Subject. Three instructors were involved in the experiment during the fall and spring semesters of the 1973-74 school year. Conventional methods of instruction, using the same course of study, were duplicated in all situations. Statistical analyses utilized in the study were analysis of covariance and multiple linear regression. It was felt that …

The lecture recital was given on August 9, 1974. Chorale partitas by Sweelinck, Scheidt, B051hm, and Walther were performed following a lecture on the chorale partita in the Baroque period. The lecture included a discussion of the instruments that the partitas were written for and the functions for which they were written. The works of Sweelinck and Scheidt and their influence on later composers were discussed. A number of lesser-known composers and their works were mentioned. Also, there was a discussion of works by well-known composers such as Bohm, Pachelbel, Buxtehude, Walther, and Bach. In addition to the lecture recital, three other public recitals were performed, all of which consisted of solo compositions for the organ. The first solo recital, including works of Buxtehude, Bach, Walther, Pepping, ?ranck, Alain, and Durufle, was performed on July 18, 1971. On August 13, 1972 the second solo recital was performed. Compositions by Greene, Stanley, Searle, Willan, Dandrieu, Roger-Ducasse, and Langlais were included in the program. The third solo recital, which included works by Sweelinck, Bach, Guillou, and Reubke, was performed on June 5, 1974. The four programs were recorded on magnetic tape and are filed with the written version of the lecture material …

This study was a simple "before" and "after" attitude measurement experiment using an experimental group and a control group. The attitude measurements were made before and after the subjects in the experimental group were presented an informational briefing about the Air Force ROTC training program. Both the experimental group and the control group were subject to exposure to the Air Force mass communication advertising during the two-month study period. The results indicate that the increased knowledge gained by the experimental group through its exposure to the informational briefing caused a negative change of attitude within the group. However, the control group had no significant change of attitude during the study period even though more than 87 percent of those subjects were exposed to some form of Air Force advertising.

The lecture recital was given April 1, 1974. Eighteenth-century accounts of the voices and performing styles of Francesca Cuzzoni, Faustina Bordoni, and Anna Strada del Pò were related to six opera arias written for them by George Frideric Handel. The arias, accompanied by harpsichord, violin, and violoncello, were performed with added original ornamentation. In addition to the lecture recital two other public recitals and two opera roles were performed. The first solo recital was on February 11, 1972, and included works by Mozart, Fauré, Rimsky-Korsakov, R. Strauss, Walton, Moore, and others. The second solo recital, on October 15, 1973, included works by Porpora, Rameau, Handel, Wolf, Donizetti, Debussy, and Schubert. The role of "Urgele" in the marionette opera Die Fee Urgele by Pleyel was performed in English on October 30 and 31, 1972, with the Collegium Musicum of North Texas State University. The role of "Clorinda" in Rossini's La Cenerentola was performed in English on November 26 and 28, 1972, with the Shreveport Symphony.

The problem of the study was to discover whether the selfconcepts of selected children in the primary grades could be enhanced. The purpose of the study was to determine the feasibility of using tape-recorded stories to enhance the self-concepts of selected primary grade children. A treatment of the Piers-Harris Children's Self Concept Scale for sex differences showed no significant differences for either the experimental or control groups. Some enhancement of the self-concepts of primary grade children may be possible by means of auditory non-teacher directed activities under properly controlled conditions. Several areas should be further investigated. A regular school year study should be designed to produce results applicable to a more general population. Such a study might answer questions regarding peer influences, the relationship between self-concept and academic achievement, the tolerance of primary grade children for prolonged treatment, and teacher attitude toward conducting such activities. Studies should be conducted to determine the relative value of simultaneous visual and auditory presentations for the enhancement of self-concept.

After independence on March 6, 1957, Ghana, under the late President Kwame Nkrumah, turned to diverse developmental activities. Economically, Ghana was on sound footing; the balance of payments was favorable and cocoa was yielding a good harvest. In 1967, Nkrumah was ousted due to his dictatorial rule. In this study the available primary and secondary sources were utilized. Primary sources were made available by the Ghana Embassy in Washington, D. C. and by friends and relatives in institutions of higher learning in Ghana. The study is divided into five chapters. Chapter I concerns itself with a geographical survey of the country, including land, climate, people, and natural resources. Chapter II explores political developments, and Chapter III examines some of the crucial economic problems. Chapter IV explores some economic progress and Chapter V makes suggestions, some of which may seem sordid and grim, but at least they offer a "stepping stone."

The problem of this study was to determine competencies which are necessary for effective administration by secondary school principals. The sources of data included a review of the literature and supplemental materials. The survey technique, employing a jury-validated questionnaire, was used to collect the perceptions of superintendents, principals, teachers, and college professors in the State of Texas. A total of 316 educators responded to the questionnaire. The development and findings of this study are presented in five chapters. Chapter I presents an introduction to the study. In Chapter II, a survey of the literature is reported. Chapter III contains details of the procedures employed in collecting data for the study. Chapter IV presents the data gathered through the use of the questionnaire. Chapter V presents the summary, findings, conclusions, and recommendations resulting from the study. The study identified eight general areas of competency for secondary school principals. Those competency areas were (1) organization and administration, (2) curriculum design and improvement, (3) the instructional process, (4) business and financial management, (5) student management, (6) personnel management, (7) facilities, equipment, and supplies, and (8) communications. A total of ninety-five competencies was identified from the literature and from communications with college professors and …

This study investigates the influence of the Austrian music theorist Heinrich Schenker on American music theory since 1940, including a survey of writings related to Schenker and theory textbooks displaying his influence. The Schenker influence on American music theory includes many journal articles on Schenker and his principal students. His methods are employed often in analytical discussions of various issues. In addition to numerous dissertations and theses written about Schenker, a number of textbooks are now based wholly or in part on his approach to musical understanding. The current trend towards accepting Schenker's theories is likely to continue as more people are exposed to his teachings.

The purpose of this study was to assess content and concurrent validity of the Torrance Tests of Creative Thinking (TTCT). The subjects were thirty-four art majors at North Texas State University between the ages of nineteen and thirty-nine. Content validity for the TTCT, as assessed by seven judges (art professors), was very high; concurrent validity was very low. Only one judge's ranking of the criterion was significantly intercorrelated with that of the other judges (p<.05). There were no significant rho correlations between the TTCT and the criterion (p<.05). The t-ratio differences between the males and females, for all tasks of the TTCT, were non-significant (p<.05). It was concluded that the TTCT were not appropriate for use with adult art majors.

This study investigates the motives behind the rhetorical strategies of rejection and acceptance used by John Bright in his four Parliamentary speeches opposing the Crimean War. Kenneth Burke's dramatistic pentad was used to evaluate the four speeches. An examination of the pentad's five elements reveals that Bright had six motives for opposing the war. To achieve his purpose in giving the speeches--to restore peace to England and the world--Bright' used the major rhetorical agencies of rejection and acceptance. Bright's act, his selection of agencies, and his purpose were all definitely influenced by the scene in which they occurred.

This study presents a picture of Martin Luther as a pioneer in mass communications. The text is divided into four sections and the conclusion; Martin Luther: man and his world, Luther and the German printing press, propaganda devices in Luther's Primary Reformation Treatises of 1520, and, propaganda and mass communications in Luther's liturgical reforms, religious broadsides, and preaching. The final remarks pertain to Luther's effect upon the reordering of society in the Western world.

This study examines ultrastructural changes occurring in seven- and fourteen-day populations of Trypanosorfa lewisi when 60 mg sodium salicylate is administered to the host. These changes were related to the host-immune response. Seven-day trypanosomes showed approximately 10 posterior volutin granules. Seven-day trypanosomes whose host had received salicylate exhibited. 30 to 40 volutin granules, and their posterior tip exhibited volutin granules in high numbers sometimes excluding other cellular elements. Fourteen-day trypanosones showed fewer volutin granules than seven-day, salicylate-treated ones. Salicylate treatment caused no additional ultrastructural alterations. Thus the volutin granules are not linked to the reproduction inhibiting antibody (ablast in) but may be involved in the formation of the trypanocidal antibodies.

This study has been undertaken to investigate the impact of group discussion upon sociometric status, selfactualization, and number of stated problems with respect to student nurses. The purposes of this study were (1) to determine whether group discussion will enhance sociometric status of student nurses, (2) to determine whether group discussion will positively affect self-actualization of student nurses, (3) to determine whether group discussion will lessen the number of stated problems of student nurses, and (4) to examine the group process and interaction of the group discussion sessions.

This study is an exploration into the Romantics' transcendence of the dualistic world view and their attainment of a holistic vision. Chapter I formulates a dichotomy between the archaic (sacrosanct) world view and the modern (mechanistic) world view. Chapter II discusses the reality of the religious experience in Romanticism. Chapter III elucidates the Romantics' use of mystic myths and noetic symbols. Chapter IV treats the Romantic transcendence of the dualistic world view and the problems of expressing the transcendental experience in aesthetic form. Supporting theories include those of Henri Bergson, Martin Buber, Samuel Taylor Coleridge, and M. H. Abrams. The study concludes by assessing the validity of the Romantic vision in the modern world.

The present study was designed to investigate whether a good reader, by the fifth grade, will have attained sufficient knowledge of the language structure to enable him to more exactly and more appropriately reconstruct mutilated texts than a poor reader, matched for verbal intelligence level. Four 250-word cloze-treated passages were administered to twelve deficient and twelve non-deficient sixth grade readers, matched according to sex and the verbal portion of the Wechsler Intelligence Scale for Children. Analyses of variance failed to show any significant differences between good and poor readers except for a weak indication that good readers produced more exact replacements.

The problem with which this investigation is concerned is the comparison of the effects of two group counseling approaches upon selected counselee characteristics. The purpose of the study was the determination of the relative effectiveness of counselor-led group counseling and leaderless group counseling upon anxiety, self-concept, and study habits and attitudes among high school seniors. Forty of ninety-six Russellville, Arkansas, high school seniors who were referred for group counseling by their high school teachers and counselors were randomly selected as subjects. Thirty of the students were assigned in a random manner to three ten-member experimental groups. Ten of the students were assigned in a random manner to a control group. Following treatment each group was reduced to eight subjects each because of poor participation by a few subjects in each group. The IPAT Anxiety Scale, the Tennessee Self-Concept Scale, and the Survey of Study Habits and Attitudes were administered to all subjects prior to and after ten weeks of treatment.

This study investigates the influence of inner-city and suburban student teaching upon adjustment and effectiveness of first-year elementary teachers, with secondary attention to their personal and professional problems of adjustment to their initial teaching location. The fifty-five subjects of this study were first-year, inner-city and suburban teachers in the Dallas area. Except for two Black females and three Anglo males, all were Anglo females. The findings of this study support the following conclusions 1. Student-teaching locale should not be the determining factor in deciding the type of school for first-year teachers. 2. Effective inner-city student teachers may be expected to be highly effective teachers in both inner-city schools and those in other locales. 3. Successful student-teaching experiences, regardless of location, can be expected to produce well-adjusted, effective teachers. 4. It can be anticipated that inner-city teachers will experience a negative change in optimism, attitudes toward teaching, general adjustment and mental health during their initial year of teaching. 5. Both suburban and inner-city teachers who enjoyed successful student-teaching experiences can be expected to have good self-perception, empathy, a favorable view of children, confidence regarding classroom discipline, and effectiveness as a teacher.

Initially, this work recognizes that college students often fail to understand or to appreciate the language of literature; therefore, a proposal has been developed that incorporates the typical methods and media of two academic areas--literature and oral interpretation--into a synchronized dual approach to the study of literature. Chapter I discusses contemporary problems of literacy in general; Chapter II explores the traditional teaching approaches of English and oral interpretation; and Chapter III develops a possible-literary communal effort by outlining a survey course in British Literature and presenting a series of exemplificative Writers Theatre scripts.Chapter IV reviews the associative problems that apparently exist between oral language and the written symbol and recommends that a companion project might demonstrate more fully the efficacy of an integrative approach to the teaching of writing.

The problem with which this investigation was concerned was the determination of group perception profiles of selected higher education faculties. These group perception profiles were based upon faculty perceptions of the ten most important criteria considered in evaluating faculty members for purposes of rank, promotion, salary, and tenure. Also, the study determined whether or not cluster profiles existed at three levels or types of institutions-- university, liberal arts, and junior college--and how such profiles differed between levels. This study had several purposes. The first was to determine how group perception profiles of higher education faculties clustered in response to perceptions of criteria considered in evaluating faculty members. The second was to determine if similar clusters existed at three types of institutions. A third was to determine differences in the proportion of teachers belonging to each identifiable cluster at each level of institution. The fourth was to determine differences in profiles according to proportions of teachers across common clusters. And finally, the fifth was to determine differences in profiles among faculty members in identified clusters at each institutional level according to biographical characteristics: age, rank, teaching experience, seniority, and highest degree held.

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 …
