Effects of Possible Compression Loading of EBR-II Subassemblies Due to Irradiation-Induced Swelling and Changes in Reactor Environment
A condition of compression loading could possibly occur to a subassembly as a result of large length changes to irradiation-induced swelling and thermal expansion. The effects of axial compression loading on EBR-II experimental and driver-fuel subassemblies were evaluated. Compression tests that were performed on the slotted top fixture of a subassembly showed that a force of 2100 lb at 900 degrees F would close the slot enough so that the core-gripper blade would not fit into the slot. Such a slot closure would prevent the subassembly from being removed from the reactor with the core gripper.

Stereochemical Elucidation Of The Tetrahydro [2.2]paracyclophane System
The purpose of this investigation is to study the Birch reduction products of [2.2lparacyclophane and of [2.2]paracyclophane- 2-carboxylic acid. The tetrahydro Birch reduction product of [2.2]paracyclophane is shown to be dl stereoisomer, with the olefins of the upper deck only partially overlapping with the olefins of the lower deck. This stereochemical elucidation is accomplished by means of a complete proton nmr analysis of the tetraepoxide derivative. A proposed mechanism supported by VB (valence bond) and MO (molecular orbital) theories for this Birch reduction process is presented.

Tauberian Theorems for Certain Regular Processes
In 1943 R. C. Buck showed that a sequence x is convergent if some regular matrix sums every subsequence of x. Thus, for example, if every subsequence of x is Cesaro summable, then x is actually convergent. Buck's result was quite surprising, since research in summability theory up to that time gave no hint of such a remarkable theorem. The appearance of Buck's result in the Bulletin of the American Mathematical Society (3) created immediate interest and has prompted considerable research which has taken the following directions: (i) to study regular matrix transformations in order to shed light on Buck's theorem, (ii) to extend Buck's theorem, (iii) to obtain analogs of Buck's theorem for sequence spaces other than the space of convergent sequences, and (iv) to obtain analogs of Buck's theorem involving processes other than subsequencing, such as stretching. The purpose of the present paper is to contribute to all facets of the problem, particularly to (i), (iii), and (iv).

A Factor Analytic Study of the Epic Self-Assessment Scales
The purposes of this study were: 1) to determine the measurement dimensions assayed by the EPIC Self-Assessment Scales; 2) to provide information necessary to'determine whether revision of the EPIC Self-Assessment Scales would be desirable, and if so, what items need revision or deletion to obtain optimum dimensional structure; and 3) to provide information relevant to possible further research using the EPIC Self-Assessment Scales. On the basis of the results, four dominant and two subsidiary factors were concluded to be the measurement dimensions assayed by the EPIC Scales. Those were identified as Self-Assurance, Physical Appearance/Physical Shape, Emotional Lability, and Verbal Competence; subsidiary factors were Social/Interpersonal Attitude and Social Behavior/Sociability. It was also concluded that revision of the Scales be undertaken, deleting the 29 bipolar scale items which did not exhibit loadings of .500 or higher on any of the six factors. It was recommended that the revised Scales include additional bipolar scale items taken from the semantic differential literature, and that the instructions to subjects be revised. Further research to establish the reliability and validity of the revised instrument was also recommended.

An Experimental Study of the Effect of a Career Education Program on Academic Achievement and Attitudes of Fifth-Grade Students
This study was designed to determine the effects of the infusion of career-education concepts into the language arts and social studies curricula of fifth-grade students. Hypotheses related to differences in mean scores of students in the experimental group and the control group on the Reading Test, Language Test, Study Skills Test of the Comprehensive Tests of Basic Skills, as well as on the total battery scores. Additional hypotheses were formulated concerning the difference between proportional mean scores on the Career Education Questionnaire and three self-concept inventories designed by Instructional Objectives Exchange. The following conclusions are based on the findings of this study: (1) Infusion of career-education concepts into content areas of the curriculum can result in the increased academic achievement of-students. This conclusion is reinforced by the fact that, statistically, the arithmetic mean scores for the experimental and the control groups were not significantly different. Gains in language expression and mechanics, reading vocabulary, and references study skills can result when students relate academic knowledge to the world of work; (2) Students' attitudes toward career education can be altered through the provision of factual information and meaningful experiences; and (3) The self-concepts of students are relatively stable and not altered appreciably …

The Process Used to Select High School Principals in the Large-City School Districts of the Nation
The problem of this study was to examine the selection process used in the appointment of high school principals in the forty-eight large-city school districts of the nation. The purposes of this study were (1) to examine how principals of high schools in large-city districts are selected, and (2) to determine the criteria considered important in the selection process. In order to conduct this investigation a questionnaire was developed. The questionnaire was validated by a twelve-member panel composed of eleven public school administrators and a former United States Commissioner of Education. Significant findings which tend to be supported by the data are: 1. Human relations skills were considered as being most important in selecting principals. 2. Superintendents placed little value on the personal traits of candidates. 3. Instructional skills ranked third in importance. 4. The selection process depended heavily on biographical data and the use of the interview. 5. Teaching experience and a master's degree are essential. 6. Assistant superintendents are involved in the selection process more often than any other group, but superintendents are most influential in the selection process. 7. School facilities, pupils, and parents are seldom involved in the selection process, and when involved, their influence is …

Localization of Color Discrimination in the Human Cerebral Cortex
This study investigated color discrimination as a possible localized function of right or left cerebral hemispheres in humans. Previous studies have shown conflicting results. Studies implicating the left hemisphere have contaminated color discrimination with verbal-symbolic ability. Other studies implicating the right hemisphere emphasized color-matching ability. This study pointed out the importance of response latency as well as accuracy and also the importance of testing the data for meeting the assumptions of the statistical technique utilized. It was concluded that color discrimination is normally a right-hemisphere function in right-handed individuals. Differences in individual ability, although large, were not found to be systematically related to sex or eye dominance, but may be learned individual differences. The study further pointed out the inappropriateness of referring to a major or dominant cerebral hemisphere without stipulating which function is being considered.

From Colony to Dominion Within the British Empire, 1914-1931
This study has been limited to those seventeen significant years from the outbreak of World War I to the passing of the Statute of Westminster, for during those years British colonial policy changed radically. An era of the domination and supremacy of the imperial parliament disappeared to be replaced with a policy of equality and partnership. This change in British colonial policy was the result of many significant events. The present study will show how those events and London's responses to them helped to bring about the consummation of the long-sought nationhood of the colonies. The results of the study have been presented chronologically. During World War I (treated in Chapter II),' the colonies supported London with troops, skilled workers, contributions and foods of all kinds. The loyalty and sacrifices of the dominions aroused the interest of the mother country and eventually led to a change in the relationship between London and the colonies. London demonstrated her new attitudes of sympathy, co-operation, and understanding in a number of ways.
