Many attempts have been made over the last several decades to improve communication among law enforcement agencies. This article is a case study of a “low-level” data sharing project in Florida that could serve as a national model. The Florida Law Enforcement Data Sharing Consortium is a partnership between the University of Central Florida and more than one hundred law enforcement agencies. It offers an inexpensive, yet technically advanced alternative to the proprietary data sharing model. Its distributed architecture was endorsed by the Markle Foundation, the 9/11 Commission, and the 2004 National Security Act. Civil liberties concerns raised by this and other types of data sharing projects are discussed.  相似文献

Fair Trade has become a dynamic and successful dimension of an emerging counter-tendency to the neo-liberal globalisation regime. This study explores some of the dilemmas facing the Fair Trade movement as it seeks to broaden and deepen its impact among the rural poor of Latin America's coffee sector. We argue that the efforts to broaden Fair Trade's economic impact among poor, small-scale producers are creating challenges for deepening the political impact of a movement that is based on social justice and environmental sustainability. The study is based on two years' research and seven case studies of Mexican and Central American small-scale farmer cooperatives producing coffee for the Fair Trade market.  相似文献

Subsequent to U.S. Border Patrol (USBP) efforts to control illegal immigration throughout the 1990s, concern arose over an apparent increase in deaths of illegal migrants as they began to undertake more treacherous routes to enter the United States from Mexico. In response, the Border Safety Initiative (BSI) was created to increase safety along the southwest border. Using multiple data sources, including the USBP BSI Incident Tracking System, this study evaluated the impact of life‐saving efforts performed under the BSI program. Results indicate that there has been no overall reduction in the rate of migrant deaths since BSI has been in operation. However, an evaluation of BORSTAR search and rescue teams and the 2003 Lateral Repatriation Program (LRP), which returned apprehended migrants from Tucson sector to less hazardous places along the border, were found to be effective in preventing migrant deaths. Policy Implications: Critics of U.S. immigration policy claim that the only way reductions in migrant deaths along the U.S.‐Mexico border can be achieved is through liberalization of immigration policy and relaxing of border security. Yet, for more than a decade, U.S. policy makers have increased restrictions on immigration and have tightened security at the borders. Considering this, alternative means must be deployed in order to save migrant lives in the near term rather than waiting for a reversal of immigration policy. This study suggests that proactive life‐saving measures implemented through a harm‐reduction strategy can have some impact on saving migrant lives.  相似文献
