This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.  相似文献

This paper investigates one of the perennial mysteries in the area of state and local finance, the provision of tax and other subsidies to business by federal, state and local governments in the face of solid evidence that such incentives do little to nothing to influence business location or job creation. The paper looks at the upsurge in such governmental aid in the last decade and considers whether this upsurge has occurred because such aid is more efficacious than it used to be or whether it has occurred for political reasons unrelated to its effectiveness.  相似文献

The United States today faces a loss of influence as a world power, a reduction in American independence as a policymaker, and a decline in the standard of living on which Americans have come to depend. History teaches that nations weaker and less productive than the United States can rise to become economic powerhouses and rapidly increase their standards of living. History also teaches that nations failing to recognize their fundamental problems will inevitably decline. American politicians must face what is abundantly clear: the United States is losing ground and must act quickly to reverse its course. This White Paper outlines what must be done. Information about the nation's current status must be analyzed and communicated. Incentives to improve the level of competence in government must be provided and maintained. The emphasis of government policy must be changed to reflect broad economic and technological interests as opposed to special interests. Savings must be encouraged and increased. Infrastructure must be improved Tax laws must be modified to help bring these changes about. Economic and technological issues must be elevated to the importance they require. American thinking must reflect the new realities: that the age of leadership through military power is over, that the requirements for success in the world of the 1990s and beyond require a sound and growing economy that is internationally competitive. The US can accomplish these goals only through foundation-shaking, comprehensive, fundamental changealong the lines we propose herein.This paper is the executive summary (with minor editing modifications) of a white paper that is available from Cornell University's Johnson Graduate School of Management.  相似文献

This paper reports on the economic contributions and impact of the Small Business Innovation Research (SBIR) Program in Michigan during the first decade. The Michigan SBIR experience is examined to learn how researchers and small businesses use the SBIR Program, whether to start or strengthen businesses, how they view SBIR after a decade, and how the program has served Michigan businesses that have successfully carried out Phase I, Phase II, and Phase III SBIR projects. From the beginning of the SBIR Program, MERRA has coordinated annual SBIR conferences for Michigan companies. The MERRA staff has helped small businesses prepare suitable R&D projects and write effective SBIR proposals. Numerous SBIR awards have resulted from MERRA supportive efforts, and the MERRA small business outreach activity has kept MERRA in touch with successful firms to assist them in getting the best results from their SBIR projects and to assess progress. For this study, in-depth evaluations were made of various Michigan firms that won SBIR awards, including both mature small businesses and start-up companies to learn in what ways their SBIR experiences are parallel and in what ways they diverge. The study covers those that have used SBIR funds to diversify and add new areas of business to existing core areas. Other companies examined were created by researchers associated with universities, industry, or research organizations who utilized SBIR awards to assist in starting new businesses. Also considered were Michigan companies at different levels of development that have employed SBIR awards as seed money to perfect innovative new products for marketing.  相似文献
