In order to examine the relationships among social network structure, types of social support, and determinants of support satisfaction, an alternative method was used to score the Social Support Questionnaire (SSQ). Factor analysis procedures suggested that college students' (N=198) social networks consisted of four groups: nuclear family, other family, friends, and others. Satisfaction with support was positively related to the proportion of the network occupied by nuclear family and negatively related to the proportion of friends in the network. Evidence was found for the presence of both support specialists and support generalists in the networks of the college students. These results are discussed from a developmental perspective with attention to the implications for interventions.  相似文献

The U.S. Bureau of Mines was established in 1910 to reduce the high accident rate in the nation's coal mines. For 85 years, it conducted a wide variety of tasks related to mining before it was abolished in 1995. The BOM had many technology transfer successes in its lifetime, including more than a dozen R&D100 awards. This essay identifies and discusses five transfer factors that can explain the success (or failure) of many Bureau of Mines projects. These five factors are termed pressure, pitfalls, path, price, and profit.  相似文献

An integrative, ecological model developed by Belsky (1980) implies that to understand child abuse researchers must examine factors at four levels: the individual, the family, the environment, and the culture. This study compared abusive and nonabusive parents at three of these four levels. At the individual level, abusers were found to have lower self-esteem than controls. Also, male abusers were likely to be relatively impulsive and hostile. At the level of the family, abusers described their children as more troublesome than control parents, but they did not perceive them as developmentally delayed. At the level of the environment, abusers identified more intense life stressors than nonabusers. Results of this investigation supported Belsky's argument that child abuse involved multiple factors and levels.  相似文献
