This article examines several recent trends in environmentalpolicy that may have important effects over the next decadeon federal-state relations and on the nation's environmentalquality. It focuses on the Environmental Protection Agency'sefforts to "reinvent" environmental regulation and to encouragecommunity-based environmental protection as a more effectiveand acceptable approach to environmental policy. We considerthe extent to which these new directions are likely to improverelations between the federal government and states, localities,and the private sector, and to achieve desired levels of environmentalprotection in the United States. The new approaches are highlypromising; yet they also face significant barriers to implementation.Congressional reform of the key statutes could lend much-neededsupport to such efforts. 相似文献

This paper reports on an exploratory study of the role of risk analysis in seven federal agencies concerned with health, safety, and environmental regulation. Interviews with key decision-makers suggest that the use of risk analysis has increased in recent years, but that its employment in risk management decision-making varies considerably both within given agencies and across agencies and policy areas. Despite methodological and institutional constraints, risk analysis is likely to play a greater role in the future as demands for comparative assessment of technological risks increase. 相似文献

When a crime victim has been injured with several different objects, it is of central importance for the forensic investigation to be able to show which object caused which injury, especially if one of the injuries was lethal. In cases of bullet penetration wounds it is often not possible to find such evidence. However, immunocytochemical investigations can accurately match a victim's injury to a particular bullet path through the body. In cases where expanding bullets have been used and the heart or liver has been struck by a projectile, it can be shown that the cells remaining on the bullet stem from those particular organs. In this case the specific cytological evidence was established by means of marking heart- and liver-specific tissue proteins with appropriate antibodies (cardiac troponin I and HepPar 1) followed by disclosure with an appropriate chromogen. Thus, in principle, cells can be used as evidence after being extracted from the projectiles by either damp cotton-wool swabs or adhesive trace evidence tape. Because of the specificity of the used immunocytochemical antibodies, finding evidence of an antigen on a particular projectile proves that it was the object that injured the organs. 相似文献

Cartels were legal to a large extent in Austria until the country’s EU accession in 1995. We examine archival material on registered horizontal cartels to learn about their inner working. Applying content analysis to legally binding cartel contracts, we comprehensively document different collusion methods along the lines described by Stigler (J Political Econ 72:44–61, 1964). Quota cartels employ regular reporting schemes and use compensation mechanisms for departures from set quotas. Specialization cartels divide markets, and rely the least on information exchange and punishment. Price and payment condition cartels primarily aim to prevent secret price cuts, requiring information provision upon request, allow for discretionary decision-taking and (sometimes immediate) punishment. These stylized facts on the contractual arrangements suggest that the possibility to write legally binding agreements was employed to address the usual obstacles to sustain collusion. 相似文献

We examine the dynamic nature of teacher skill development using panel data on principals’ subjective performance ratings of teachers. Past research on teacher productivity improvement has focused primarily on one important but narrow measure of performance: teachers’ value-added to student achievement on standardized tests. Unlike value-added, subjective performance ratings provide detailed information about specific skill dimensions and are available for teachers in non-tested grades and subjects. Using a within-teacher returns-to-experience framework, we find, on average, large and rapid improvements in teachers’ instructional practices throughout their first 10 years on the job as well as substantial differences in improvement rates across individual teachers. We also document that subjective performance ratings contain important information about teacher effectiveness. In the district we study, principals appear to differentiate teacher performance throughout the full distribution instead of just in the tails. Furthermore, prior performance ratings and gains in these ratings provide additional information about teachers’ ability to improve test scores that is not captured by prior value-added scores. Taken together, our study provides new insights on teacher performance improvement and variation in teacher development across instructional skills and individual teachers. 相似文献

When making its case to Congress and other audiences the Conservation Technical Assistance program of USDAIS Soil Conservation Service, which is the federal government's most extensive and expensive soil conservation program, based its argument on data about its clients. Missing have been comparisons between clients and nonclients that address the issue of whether clients might not have exhibited just as good conservation behavior without the program. Using multiple regression analysis that relates the diversity of conservation practices used to farm operators' receipt lnonreceipt of technical assistance, and controlling for relevant other variables, this study found statistically and substantively significant program effects in each of six diverse survey sites. 相似文献

Capoeira4Refugees is an NGO that uses the Afro-Brazilian art form of Capoeira to promote psychosocial well-being in children affected by conflict and occupation. Capoeira4Refugees introduced the Most Significant Change (MSC) methodology to monitor and evaluate project implementation and impact across two locations in the Middle East. Analysis of interviews conducted with five field staff revealed that in line with, and building on, previous research, MSC became an empowering tool that led to staff development. The potential for MSC to build staff reflexivity, independence, and leadership has implications for other organisations working in conflict areas, particularly in situations of remote management. 相似文献
