Concepts of federalism are briefly rmiewed with the intent of inquiring whether the states have become entrepreneurial as a result ofthe Reagan devolution. An overview of the contributions to the symposium suggests that support for a theory of cyclicality is not consistently evident in the states. Necessary resatrcesarenotalways present toallow thestates to bethe policyentrepreneurs in the United States. 相似文献

Relationships among major life events, perceived social support, and psychological disorder were assessed in a sample of older adolescents. Negative life events and satisfaction with social support were significantly and independently related to a range of psychological symptoms. Further, the relationship between negative events and disorder was moderated by gender, the types of events experienced, and anticipated change in the psychosocial environment. The importance of the use of standardized and psychometrically sound measures of life events, social support, and psychological disorder is highlighted.Received his Ph.D. from UCLA in 1980.

A total of 36 ancient human remains from 12 individuals (three tooth/bone samples each) and one sample each of three individuals from the newest time was typed in a blind study using the amelogenin sex test. Prior to this molecular sex determination the sex of the individual was determined morphologically. The success rate of the amelogenin amplifications was >90%. For every individual an unambiguous molecular sex typing result was obtained. Furthermore, the morphological and molecular sex determinations were in accordance with each other, giving evidence for the authenticity and ancient origin of the polymerase chain reaction (PCR) amplifications. 相似文献
