This study investigated the incidence of peripheral hearing loss in sickle cell anemia and the possibility of central auditory nervous system involvement. Nine Black subjects with sickle cell disease and nine with normal hemoglobin were administered an auditory test battery. There appeared to be no correlation between number of crisis episodes, duration of symptoms, severity of symptoms, and audiologic manifestations. Acoustic reflex testing suggested the possibility of "aired neural function in the sickle cell group. Whether impaired function was due to peripheral VIIIth nerve or to central brain stem involvement could not be determined. Results of the central auditory test battery suggested the possibility of impaired or reduced central auditory function in subjects with sickle cell anemia.

This study isolates the impact of certain factors upon the decision making of the United States Supreme Court. Selected group theory methodology is applied to the Court's decisions from 1969 through 1973. The group structure of the Court, the impact of personnel change, and the effect of judicial attitudes on public policy are explored and statistically measured with a chisquare. Schubert's bloc analysis and a Guttman scale are used to order the data. Conclusions include that two stable blocs existed on the Court during these years. Personnel change is demonstrated as causative of alterations in judicial behavior. Seven of eight groups of cases are shown to stimulate values of the Justices. Suggestions are made for further research.

This thesis examines the symbolism of thirty-five slave songs that existed in the pre-Civil War South in the United States in order to gain a more profound insight into the values of the slaves. The songs chosen were representative of the 300 songs reviewed. The methodology used in the analysis was adapted from Ralph K. White's "Value Analysis: The Nature and Use of the Method." The slave songs provided the slaves with an opportunity to express their feelings on matters they deemed important, often by using Biblical symbols to "mask" the true meanings of their songs from whites. The major values of the slaves as found in their songs were independence, justice, determination, religion, hope, family love, and group unity.

The purpose of this study was to examine the effects of news commentary on the image of political candidates. Subjects were exposed to a political debate, which was followed by three experimental manipulations of a news commentary. One group saw a commentary biased toward one candidate and against the other. In a second group the bias was reversed. A third experimental group saw a neutral commentary and the control group viewed the debate but no commentary. The primary statistical analyses used were a multivariate analysis of variance, a multiple discriminant analysis and a factor analysis. The results indicated that the commentary did have some effects on the perception of the candidates' images. Furthermore, the commentaries affected the amount of the candidates' message which was recalled by the subjects, and cued the subjects to recall specific issues which were mentioned in the commentaries. Finally, the factor analysis indicated certain characteristics of the images of political candidates.

This investigation deals with a change of congressional attitude concerning violence in entertainment media, from noninterference to investigation to initiation of research. The data are primarily from official government records. This study first examines a period of congressional reluctance to interfere with the violent content of movies and radio in 1929-45. Next examined is the period 1945-68, when Congress actively investigated media violence,, focusing on television. Finally, the study examines congressional activity concerning television violence in 1968-74 and the Surgeon General's report on television violence. This report concludes that, by 1955, the pattern of congressional interest in media violence had turned from reluctance to activity, -and discusses the likelihood of future control of television program content.
