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 μr and s?r of the parameters of a truncated normal distribution and (ii) estimators μc 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. 相似文献

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. 相似文献

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. 相似文献

Summary Emphasis throughout this paper has been placed on the importance of viewing black patients in their current social context. The positive impact of the Black Power movement has been observed in black patients who are involved in issues of black separatism and activism. Bennett's four stages of black process provide a means of identifying the position of individual blacks in terms of racial identity. Since relationships with whites are highly determined by the black patient's stage of black process, use of this conceptual frame work will assist the therapist in determining the indirect way in which black patients express racial issues.The author's experience has confirmed the existence and importance of two problem areas: the longer time needed to establish a therapeutic alliance in interracial work and the lack of knowledge of the black experience and culture in the white professional. The knowledge that additional time must be expended by both therapy partners must raise questions about the ethics of interracial practice and the need for more black mental health professionals. The second area of concern, the white professional's lack of knowledge, could be remedied. The fact that whites have not attempted to learn more about the black culture suggests the problem is a philosophical one. Liberal professionals are generally committed to the ideal of a truly integrated society where there are no differences among people. Black people appear to be telling us that they are different from whites here and now, and they like the difference.Supported by U.S.P.H.S.

Rainwater's assertion that blacks have low self-evaluations because they receive more negative evaluations from other blacks than whites receive from other whites is challenged here by reference to Heiss and Owens evidence that negative self evaluation among blacks is limited to work-related traits. Substantial support was found for our major hypotheses that, compared to whites, (1) blacks would report more negative evaluation of “most men” but not of “most women” (since the provider role is traditionally ascribed primarily to men), and (2) the more negative evaluation of “most men” by blacks would be limited to work-related traits. 相似文献
