Congress plays a central role in national environmental policy formation but appears ill equipped to set policy priorities and devise integrative legislation. Fragmentation of authority among a multiplicity of committees and subcommittees, especially in the House, contributes to these problems. This pattern is evident in the evolution of Superfund, the national program to clean up abandoned hazardous waste sites. The prolonged process of reauthorization in the 1980s contributed to serious program delay and failed to resolve a number of fundamental questions concerning the national cleanup effort. Institutional reforms could contribute to a more effective congressional role in future environmental policy deliberations. 相似文献

The purpose of this study is to examine the participation of criminology and criminal justice graduate departments at the 1977-1979 American Society of Criminology meetings. Results show that institutional prestige. not productivity, is the leading predictor of meeting participation. In addition, meeting participation does not appear to be influenced by meeting site. Finally, it is suggested that criminologists focus more attention upon professional activities in order to facilitate our understanding of criminology as a science. 相似文献

Prior research has not examined the validity of Uniform Crime Report (UCR) “reported crime” figures on the offense of arson. The reporting of arson is distinguished from that of other index offenses by the requirement that an investigation occur that establishes that a fire has been purposefully set or attempted; the counting of all arsons regardless of their occurrence with other offenses; the detection and reporting of the offense by noncitizens; and the infrequent existence of exclusive police jurisdiction. Because of these unique characteristics, past approaches to assessing the validity of data on index crimes, such as a comparison with victim reports of crime, are not possible or appropriate. In this study UCR data on arson are compared with data obtained through a national survey (n=683) of fire departments. The comparisons indicate that UCR data are significantly lower than the rate of arson reported by local fire departments both overall and across all regions of the country. 相似文献

This essay examines the ways in which women lawyers of two generation–the pioneer generation of the 1880s and the "new woman" generation of the 1910s–confronted the dilemma of marriage and career. Members of the Equity Club in the 1880s revealed three distinct sets of attitudes toward balancing marriage and career: the separatist approach that a professional woman must remain single; the Victorian attitude that a married woman must sacrifice her career; and the integrated approach that a woman could have both marriage and career. Women lawyers surveyed by the Bureau of Vocational Information in 1920 revealed that the "new woman" generation of women lawyers lived in an era of transition. While they shared the same separatist, Victorian, and integrated views toward marriage and law practice as did women lawyers in the 1880s, they also embraced the new values of the early 20th century which shaped both the contours of the legal profession and the parameters of women's lives. Set within the context of the new values of the era, the separatist, Victorian, and integrated approaches to resolving the dilemma of marriage and career, which were originally formulated by women lawyers in the late 19th century, assumed new meanings for women lawyers in the early 20th century. 相似文献
