The four structural elements of action identified in Talcott Parsons' The Structure of Social Action—means, ends, conditions, norms—can be directly assimilated to the four variables which generate the AGIL schema: instrumental, consummatory, external, internal. The former set primarily define the unit act; the latter are generalized to the action system level.  相似文献

Multiple studies have concluded that manual patient transfer and repositioning techniques are a significant cause of low back injuries. The objective of this study was to compare the low back stresses resulting from the use of two different mechanical patient transfer assist devices with the use of traditional manual transfer techniques. The mechanical transfer systems used were the Barton Patient Transfer System and a Sling-Suspension Lift similar to a "Hoyer Lift". The back compressive forces derived using the Michigan 3D Static Strength Model (Version 4.0) and electromyography (EMG) of the muscles of the low back were compared. This study found that the mechanical assist devices placed less stress on the low back and were more desirable to use than the traditional manual techniques. The Barton System was found to be, in general, less hazardous and more preferred than the Sling Suspension Lift.  相似文献

This study draws on the experience of six social workers who are adult children of alcoholics, to demonstrate that childhood learned responsibility and the capacity for attachment are translated into later professional acuity. The place of resilience in developing an understanding of the linkages between the experiences of adult children of alcoholics and social workers is examined and the consequences for social work practice and the education of social workers is outlined. Undeniably, prior life experience impacts on practice. Less well understood is the positive impact of negative experience. In the case of social workers who are adult children of alcoholics we argue that being part of an alcoholic family may significantly contribute to, rather than detract from, later practice competence.  相似文献

Research has extensively examined matching on race and other characteristics in cohabitation and marriage, but it has generally disregarded sexual and romantic relationships. Using data from the 2002 National Survey of Family Growth and the National Longitudinal Study of Adolescent Health, we examine the tempo of key transitions in the recent relationships of young adults aged 18 to 24. We focus on how the racial mix of partners in relationships is associated with the timing to sex, cohabitation, and marriage. We find evidence that relationships between white men and minority women proceed more rapidly than relationships involving other racial combinations from romance to sexual involvement and from sexual involvement to cohabitation. Our findings have important implications for social exchange perspectives on mate selection.  相似文献

Research on religious giving in the United States contains several important lessons. Denominations differ immensely in their giving levels, with conservative Protestants giving the most, liberal Protestants giving at moderate levels, and Catholics giving the least. Personal religious commitments and the level of one's disposable income are the main determinants, but, in addition, interpersonal factors produce a strong skew in the amounts given. Annual pledging and deliberate planning of giving have clear effects.  相似文献

Srivastava (1980) has shown that Grubbs's (1950) test for a univariate outlier is robust against the effect of equicorrelation. In this note we extend Srivastava's result by giving a more general covariance structure, which relaxes both the covariance structure and the assumption of equal variances. We also show that under the more general covariance structure, the power of Grubbs's test, as well as the significance level, is identical to the independently and identically distributed case.  相似文献
