ELECTRON-SLOWING-DOWN SPECTRUM IN Cu OF BETA RAYS FROM Cu$sup 6$$sup 4$

Description: The electron flux spectrum resulting from the slowing down of electrons from /sup 64/Cu uniformly distributed in Cu was measured from 0.1 ev to 37 kev for both a plane disk source and a black body cavity source. The cavity source consisted of a hollow Cu frustrum with walls infinitely thick for /sup 64/Cu beta rays. A matching thick cover allowed only electrons from inside the cavity to enter the Keplertron, a spherical electrostatic beta spectrometer. The cavity data agreed well from 1 kev to 37 kev with a simplified calculation of the Spencer-Fano theory. Below 1 kev, the experimental flux exceeded the calculated flux by as much as 35% at 30 ev. A stopping power derived from proton dath was used in the theory for electrons below 5.5 kev. A buildup of several orders of magnitude in the electron flux below 1 kev was observed. The disk data was lower than the cavity data at all energies above 1 kev, the former approaching the latter at higher energies. The beth spectrometer was calibrated for transmission and resolution from 1.5 ev to 3 kev using an isotropic electron gun and at 31.4 kev using the /sup 152/Sm Auger line. (auth)

THE EFFECT OF THE $sub 4$TENDENCY TO REPORT INJURIES$sub 4$ ON MINOR ACCIDENT STATISTICS: A FOLLOW-UP STUDY

Description: Thesis submitted to Univ. of Tennessee, Knoxville. Statistical methods were used in an attempt to determine the effect of the tendency to report accidents on the systemic variance in minor injury data over a 6-yr period. The population surveyed included 245 journeymen of 9 skilled craft groups continuously employed during the period. Results indicate that injury and non- injury visits to the dispensary were relatively stable during the 6-yr period and that there was a significant positive relation between non-occupational and injury visits during the period of study.

CHROMOSOMAL ABERRATIONS IN A NATURAL POPULATION OF CHIRONOMUS TENTANS EXPOSED TO CHRONIC LOW-LEVEL ENVIRONMENTAL RADIATION

Description: The salivary gland chromosomes of Chironomus tentans larvae collected from White Oak Creek, an area contaminated by radioactive waste from the Oak Ridge National Laboratory, and from six uncontaminated areas were examined for chromosomal aberrations. White Oak Creek populations were exposed to absorbed doses as high as 230 rads per year or about 1000 times background. Chromosomal maps were constructed to make a general comparison of the banding pattern of the salivary chromosomes of the C. tentans in the East Tennessee area with those of Canada and Europe. These maps were used as a reference in scoring aberrations. Fifteen different chromosomal aberrations were found in 365 larvae taken from the irradiated population as compared with five different aberrations observed in 356 larvae from six control populations, but the mean number of aberrations per larva did not differ in any of the populations. The quantitative amount of heterozygosity was essentially the same in the irradiated and the control population, but there were three times the variety of chromosomal aberrations found in the irradiated area. From this evidence it was concluded that chronic low-level irradiation from radioactive waste was increasing the variability of chromosomal aberrations without significantly increasing the frequency. It was also concluded that chromosomal polymorphism can be maintained in a natural population without superiority of the heterozygous individuals. (C.H.)

A history of the clarinet and its music from 1600 to 1800

Description: It is the purpose of this thesis to present a study of music written for the clarinet during the period from 1600 to 1800. The first part is a history of the clarinet showing the stages of development of the instrument from its early predecessors to its present form. The second part deals with composers and their music for the clarinet.

An investigation of the effectiveness of programmed learning in the teaching of harmonic dictation in a beginning college music theory course

Description: The problem of the study was to investigate the comparative effectiveness of two methods of teaching harmonic dictation to beginning college music students. The methods were (1) the conventional teacher-classroom approach as suggested by Robert Ottman's Elementary Harmony, and (2) a linear programed book to be used in conjunction with a series of tape recordings.

The Relationship between Acceptance by Peers and Acceptance of Self

Description: This study investigated the adolescent self-concept. The concern was with the relationship between peer status as measured by a reputation scale and self-concept as measured by how an individual feels he is perceived by others.

Teacher Judgments as Related to Certain Predictors of Artistic Creativity in Senior High-School Students

Description: The problem of this study was to ascertain the degree and kind of relation which might exist between a) certain measured indices of general creativity, ingenuity, and artistic judgment, and b) teacher judgments of artistic creativity within a senior high-school art population. One of the major purposes of this study was to identify a test or tests of creativity which might be used with senior high-school students to find those students with artistic potential who either should be counseled into art classes or for whom particular kinds of teaching procedures should be developed.

Analysis of the Interrelationship of Intelligence, Achievement, and Socio-Economic Status in a Selected Population of High-School Seniors

Description: The problem of this study was to determine the interrelationship of intelligence, socio-economic status, and ten subtest measures of achievement in a selected population of high-school seniors. In addition to the general problem, the specific problems were as follows: 1. To determine the relative independence of dependence of each of the variables in relation to their influence on each of the other variables. 2. To determine the degree of predictive validity with which behavioral regression equations can be used in terms of intelligence, achievement, and socio-economic status.

A Comparative Analysis of the Results of Two Approaches to Reading Instruction upon Seventh Grade Students

Description: This study was concerned with making a comparative analysis of reading skills development resulting from two different approaches to reading instruction at the seventh-grade level. The two approaches were: (a) instruction emphasizing specifically the reading skills, Approach A, and (b) instruction using the regular classroom activities approach, Approach B.

Self-Appraisal Related to the Professional Development of Faculty Members in Schools of Business

Description: The problem of this study was to develop and analyze a useful approach to the professional development of faculty members in schools of business through the technique of self-appraisal. This study contained the following subdivisions: (1) a review of current college faculty development practices, (2) a review of current executive development practices within industry, (3) an explanation of the philosophy and technique of self-appraisal in professional development, (4) an application of the technique in six institutions of higher education, and (5) an analysis of results obtained from these institutions along with some suggestions for further research.

Some Effects of Learning the Causes of Behavior upon Certain Personal and Social Attitudes of Pre-Adolescent Children

Description: The problem of the present study is to determine what changes will take place in certain personal and social attitudes of pre-adolescent children at the fourth- and fifth-grade levels as a result of their "having learned about the factors that underlie behavior" through a mental hygiene program utilizing "causally" oriented materials at their own level of interest and understanding.

A Comparative Analysis of Selected Characteristics of Intellectually Superior Male Students who Persist and Those who do not Persist in an Advanced Placement Program

Description: This study made a comparative analysis of certain selected characteristics of a group of academically able male youth who persisted and those who did not persist in a five-year academic sequence in mathematics and science. Two major questions were dealt with in this study: 1. Can the persisting youth as a group be distinguished from those youth who did not persist in this academic sequence on the basis of their functioning in certain nonintellective areas? 2. Are the performances of the persisting youth on certain dimensions elevated in the same directions as are the performances of mature creatives who have been intensively studied on the same dimensions?
