Abstract This paper reviews graduate applications/admissions data for 1975–84, and shows that as applications have decreased, the acceptance rate has increased. Referring to the NASW Code of Ethics, the paper suggests this trend raises a number of ethical issues with which the field should be concerned. Traditional alternatives to liberalized admissions are also reviewed and their perceived efficacy is examined. It is suggested that hold-harmless strategies are insufficient to counteract the societal trends which adversely affect graduate social work education and, further, that the field must begin to proactively plan for fewer, or at least smaller, graduate programs. 相似文献

A regression approach to principal component analysis is presented in this note. We provide an alternative interpretation of principal components that illustrates the relation between the extra sum of squares in regression analysis and the eigenvalues associated with the principal components. 相似文献

Continuing the studies of Johnson et al (1980) and Johnson and Kotz (1981), further distributions arising from models of errors in inspection and grading of samples from finite, possibly stratified lots are obtained. Screening, and hierarchal screening forms of inspection are also considered, and the effects of errors on the advantages of these techniques assessed. 相似文献

Age at first marriage in Malawi: a Bayesian multilevel analysis using a discrete time-to-event model 总被引:4,自引:0,他引:4

Summary. The paper presents a hierarchical discrete time survival model for the analysis of the 2000 Malawi Demographic and Health Survey data to assess the determinants of transition to marriage among women in Malawi. The model explicitly accounts for the unobserved heterogeneity by using family and community random effects with cross-level correlation structure. A nonparametric technique is used to model the base-line discrete hazard dynamically. Parameters of the model are computed by using a Markov chain Monte Carlo algorithm. The results show that rising age at marriage is a combination of birth cohort and education effects, depends considerably on the family and to some extent on the community in which a woman resides and the correlation between family and community random effects is negative. These results confirm a downward trend in teenage marriage and that raising women's education levels in sub-Saharan Africa has the beneficial effect of increasing age at marriage, and by implication reducing total fertility rates. The negative correlation between family and community random effects has policy implications in that targeting communities with an intervention to increase age at first marriage may not necessarily yield reduced fertility levels in individual families. A campaign that is geared towards individual families would achieve the desired goals. Overall, the findings point to the need for the Government in Malawi to enact public policies which are geared at vastly improving women's education at higher levels. The variation in marriage rates over families poses problems in delivering the policy, since particular policies must be devised for specific groups of families to accomplish the required social and health objectives. 相似文献

We develop and test a model of nonprofit executive compensation based on theories of organizational science, economics, and agency theory. Our sample consisted of 114 directors of small business development centers in the United States. Consistent with our model, we find significant effects for human capital, organizational size, and organizational affiliation. We find tentative support for a significant pay‐for‐performance relationship. We find that when education, tenure, size, performance, and affiliation are held constant, female executives are compensated significantly less than male executives. 相似文献
