The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal.  相似文献

Technology transfer has generally had little impact on the assistive technology industries serving small, highly fragmented “disability markets.” Persons with disabilities often require specialized, relatively sophisticated technology. Third-party payer reimbursement rates and the low levels of disposable income among disability populations often cap product pricing. Transferring technology to these industry segments therefore poses special challenges. In October 1998, the Rehabilitation Engineering Research Center on Technology Transfer initiated the “Demand-Pull Project on Wheeled Mobility.” Successful transfers resulting from this project demonstrate that a systematic technology transfer process can be successfully applied to industries serving specialized and underserved niche markets.  相似文献

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

In 1970, the Congress enacted the Organized Crime Control Act. Title IX of the 1970 Act is the Racketeer Influence and Corrupt Organization Act or RICO. This Act had its origins in legislation going back as far as 1934, but coming forward to 1961. The 1970 Act borrowed ideas from this earlier legislation, principally “enterprise,” but also the use predicate statutes to define “racketeering activity.” The ideas are not new, but their combination affects how prosecutors and law enforcement agents investigate, try, and sanction violations of the Act. RICO’s drafting also reflects organizational theory and economic analysis. The investigation and prosecution of a single crime committed by an individual on a single day and in a single place maybe done using one set of procedural and evidentiary rules. Nevertheless, the investigation and prosecution of patterns of diverse offenses committed by, through, and against licit and illicit enterprises require sophisticated procedures, evidentiary rules, and criminal sanctions. In addition, antisocial conduct is more than a challenge to the administration of criminal justice; it also requires the full panoply of civil sanctions, including public injunctions as well private enforcement of injunctive relief and treble damages. RICO has had a profound effect on the prosecution of organized crime, white-collar crime, and other forms of similar criminal behavior. William J. & Dorothy K. O’Neill Professor of Law, Notre Dame Law School; A.B. 1957, University of Notre Dame; J.D. 1960, Notre Dame Law School. Professor Blakey was the Chief Counsel of the Subcommittee on Criminal Laws and Procedures of the United States Senate Committee on the Judiciary in 1969-70 when the Organized Crime Control Act of 1970, Pub. L. No. 91-542, 84 Stat. 922 (1970) was processed, Title IX of which is the Racketeer Influence and Corrupt Organization Act or RICO. For a general treatment of the statute from a variety of perceptive, see the collection of law review literature in G. Robert Blakey & Kevin Roddy, “Reflections on Reves v. Ernst & Young: Its Meaning an Impact on Substantive, Accessory, Aiding, Abetting and Conspiracy Liability under RICO,” 33 Amer. Crim. L. Rev. 1345, 1348 n. 3(1996).  相似文献
