"One can often gain insight into the aetiology of a disease by relating mortality rates in different areas to explanatory variables. Multiple regression techniques are usually employed, but unweighted least squares may be inappropriate if the areas vary in population size. Also, a fully weighted regression, with weights inversely proportional to binomial sampling variances, is usually too extreme. This paper proposes an intermediate solution via maximum likelihood which takes account of three sources of variation in death rates: sampling error, explanatory variables and unexplained differences between areas. The method is also adapted for logit (death rates), standardized mortality ratios (SMRs) and log (SMRs). Two [United Kingdom] examples are presented."  相似文献

An innovative model for the training of social welfare students in the special skills essential in child welfare work is predicated upon a classification system of children at risk and a continuum of services.  相似文献

The extended family and informal adoption practices of the black culture are frequently misunderstood by workers from different backgrounds. Particularly prominent is the responsibility for child rearing assumed by older family members. The authors present procedures, issues, and argument for use of a group method to strengthen the coping abilities of these families through attention to the needs of their senior members.  相似文献

Neighborhood opposition to community-based treatment centers (CBTCs) has prompted fears that these centers will become concentrated in inner city, "transitional neighborhoods." These neighborhoods are thought to lack the willingness and/or resources to oppose CBTCs. This paper examines the distribution of CBTCs in a northern metropolitan county. The findings suggests that the fears of "ghettoization" may be real only for certain types of centers. Most centers were located in higher-status city and suburban neighborhoods. However, these centers were physically or visually isolated from the surrounding housing, making them less likely to attract attention and therefore less likely to arouse neighborhood opposition.  相似文献

Recent environmental changes have brought about modifications in the strategic planning practices of multinational businesses. These modifications in the strategic planning practices were studied through the medium of in-depth interviews with planners in a number of concerns. Of the several changes observed, predominant are the shortening of time horizons and the increase in flexibility. Equally noteworthy is the surprising lack of change in the social concern of a number of the organizations. This article summarizes a study of the effects of environmental changes on multinational-business planning.  相似文献
