The EU has regulated chemicals since the late 1960s using both general and sectoral legislation, and exposure-based, hazard-based and risk-based decisions. A new proposal from the European Commission – on the Registration, Evaluation and Authorization of Chemicals (REACH) – will build on the experiences of the existing legislation and introduce some new concepts in the management of chemicals. This article is aimed at assessing the current chemical control mechanisms in the EU and those put forward in REACH to demonstrate how REACH is a new paradigm in chemicals management. REACH will carry forward today's experience and approach to the management of chemicals in the EU and introduces some novel aspects, such as utilizing market-based mechanisms and putting into operation the 'substitution principle'.  相似文献

Conclusion With the passage of the Administrative Dispute Resolution Act, the stage was set for innovation and change in federal agencies. Now, part way into the five-year life of the Act, a new administration has the potential to encourage even wider use of ADR at the federal level, providing still more examples from which to develop a clearer sense of best practice. Additional funds, both for ACUS and individual agencies, are vital to providing the level of experimentation, innovation, and documentation needed to ensure success.MIT ProfessorLawrence E. Susskind is director of the MIT-Harvard Public Disputes Program, 512 Pound Hall, Harvard Law School, Cambridge, Mass. 02138.Eileen F. Babbitt is associate director of the Public Disputes Program.Phyllis N. Segal is a practicing mediator with Endispute, Incorporated.The authors would like to acknowledge the federal dispute resolution specialists who contributed greatly to our work by providing interviews and materials for this article: Cathy Costantino of FDIC; David Batson of EPA; John Settle and Ron Walczak of HHS; David Drabkin of DLA; Jim Jones of DOL; Sheldon Guttman of FCC; Charles Pou of ACUS; Jeff Domber of GSA; and Diane Liff of DOT.  相似文献

This article contributes to the development of theories on European integration by testing and exploring statistical models on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003. We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic models might be an interesting avenue for future conceptualizations of the EU integration process. This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to thank the seminar participants for useful comments.  相似文献
