ESTIMATING THE PARAMETERS OF NORMAL AND LOGISTIC DISTRIBUTIONS FROM CENSORED SAMPLES1

Let g(z) be the ratio of the ordinate and the probability integral of the distribution of a variate z. The relation g(z)～+βz is used to derive (i) estimators μ_r and s?_r of the parameters of a truncated normal distribution and (ii) estimators μ_c and s?_c of the mean and standard deviation of a logistic distribution from doubly censored samples. The variances and eovariances of these estimators are obtained. They are shown to be nearly as efficient as the maximum likelihood estimators and easier to compute.     

Wirth,Whiskey, and WASP's: Some Consequences of Community Size for Alcohol Use*†

Several themes in Wirth's “Urbanism as a Way of Life” generate the prediction that alcohol use (versus nonuse) will be more widespread among residents of urban areas. Multiple regression analysis of data from two recent national polls (1966, 1968) reveals support for this prediction. With eight other key sociological variables simultaneously controlled, the greater the urbanism of a community (measured in terms of community size), the greater the proportion of alcohol users it contains. To make certain that this association is due to urban conditions (as opposed to merely the absence of rural forces which encourage abstinence), the effects of rural forces are reduced by omitting the most rural categories of the community size measure of urbanism, and the data are reexamined. The association still persists, basically because of the larger proportion of middle to upper status, white, and Protestant alcohol users in the more urban areas.     

Perceived importance of “social goals” in business organizations

Business organizations operate within a complex socio-technical environment. Interactions between these socio-technical dimensions and the managers' personal value systems are thought to influence managerial role patterns and decisions. This paper investigates shifts in perceived importance of “social goals” from a set of organizational goals. The research concludes that there has been no significant changes occurring in either the ordering or the clustering of organizational goals.     

Children's reactions to sibling loss

Loss of a child is a severe trauma to the members of any family. Although the reactions of parents to the loss of a child has received a considerable amount of attention in the literature, relatively little has been written about the impact of such a loss on the remaining sibling(s). The effect of sibling loss on a child is complicated by many factors; among them are the tendency of children to deny the reality of death and the feelings associated with this experience, as well as the manner in which the parents are able to cope with the loss. This article reviews the available literature and calls for more research dealing with the impact of the loss of a child on the entire family system.     

Toward the Management of Heterosexual Jealousy*

The findings of a recent study of extradyadic involvements and sexual jealousy among college-age couples are reported. Evidence is brought to bear in support of the principle finding that several aspects of the jealousy experience (eliciting factors, manner of expression) can and do vary widely among individuals. Despite the apparent universality of the jealousy phenomenon, communication in couples is inhibited by the social disapproval associated with its occurrence, and consequently discrepancies such as those evidenced in this study may pass entirely unobserved. As a result, jealousy problems remain unresolved and may serve to trigger further dissension. In light of these findings, developing communication skills is identified as the appropriate treatment mode for sexual jealousy.     

Socioeconomic Achievement and Religion: The American Case

Religious preference at several points in the life cycle is examined with regard to its affect on socioeconomic achievement and with regard to how religious preference is influenced by education, occupation, and income. The importance of considering the several major denominations separately instead of as a single category is demonstrated. When this is done Jews, Presbyterians, and Episcopalians have above average socioeconomic achievements; Methodists and Catholics are near the mean; and Baptists are below the average. Controlling for social origins and early achievements greatly attenuates the differences, but does not remove them with regard to education and income.
