In 2017, significant media and political interest was sparked by the UK decision to leave Euratom, the European Atomic Energy Community. While such interest in nuclear matters has to be welcomed, the apparent lack of knowledge displayed in the regulatory governance of the UK nuclear industry is disquieting. This article therefore offers an overview of the publicly funded UK nuclear industry and its regulatory governance including its links with European and global nuclear agencies to inform the debate and to identify critical issues in need of resolution.  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.

Science policy analysts have traditionally classified R&D laboratories as government, private, or university. The authors argue that this view is outmoded and provides little help in understanding the rapidly changing environment of R&D laboratories. They provide and test an alternative scheme designed to cope with “sector blurring” and the intermingling of market and political influences on R&D laboratories. The authors also discuss implications of their scheme for a variety of contemporary science policy issues.  相似文献

HOLDING: In the accelerating rush to judgment that occurred here, a series of legal errors and missteps following a preliminary hearing compounded what was already an excruciatingly difficult and complex situation. The record strongly suggests that no one involved in the protective proceeding had ever communicated directly with baby AMB's parents and only the testifying doctor had ever seen AMB, an infant with life-threatening disabilities. Thus, a duly enacted statutory process designed to protect individual rights, to allow the intelligent exercise of these rights, and to assure balanced and considered decision making became, instead, the opposite. There was such a relentless disregard for basic principles of law that in its opinion, the Michigan Court of Appeals attempted to assure that this tragedy is never repeated in that state.  相似文献
