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

This article presents a conceptual framework for describing cases involving children with special needs that are increasingly being seen in family court. Three categories that represent the most common of such cases include (1) acute, life-threatening medical conditions; (2) chronic developmental disorders; and (3) psychological and behavioral syndromes. After detailing the nature of the disabilities in each category, perspectives from the bench are offered with specific recommendations and general strategies for effective case management. This is followed by a proposal of an innovative conceptual model—the Individualized Parenting Plan (IPP)—that organizes and integrates nine domains essential for a comprehensive parenting plan for special needs children. The article concludes with a list of sixteen strategic guidelines for servicing the families of these special needs children, in their best interests.  相似文献

Despite their rich theoretical and practical importance, criminologists have paid scant attention to the patterns of crime and the responses to crime during exceptional events. Throughout the world large-scale political, social, economic, cultural, and sporting events have become commonplace. Natural disasters such as blackouts, hurricanes, tornadoes, and tsunamis present similar opportunities. Such events often tax the capacities of jurisdictions to provide safety and security in response to the exceptional event, as well as to meet the “routine” public safety needs. This article examines “routine” crime as measured by calls for police service, official crime reports, and police arrests in Salt Lake City before, during, and after the 2002 Olympic Games. The analyses suggest that while a rather benign demographic among attendees and the presence of large numbers of social control agents might have been expected to decrease calls for police service for minor crime, it actually increased in Salt Lake during this period. The implications of these findings are considered for theories of routine activities, as well as systems capacity.  相似文献

A study of the various stressors faced by interns serving as security assistants at the Tenth Pan American Games and the coping mechanisms they utilized was undertaken during the months of July and August 1987. This study revealed that group development can be altered and maladaptive behavior can result among students experiencing high degrees of stress, frustration, and feelings of helplessness, who are subject to a leadership void. The data strongly support the need for planners of similar large-scale internship programs to consider group processes, organizational factors, and interpersonal relations if organizational goals are to be achieved, maladaptive coping mechanisms are to be avoided, and student stress is to be lessened.  相似文献

This study used data from 299 police officers from 12 municipal police departments across the state of Virginia to determine the relationship between education and police performance. Performance was measured by supervisor evaluations of each officer's overall performance, communication skills, public relations skills, report writing skills, response to new training, decision making ability, and commitment to the police department. Significant correlations were found between education and most measures of performance. Most importantly, the results show a significant correlation between overall performance and education (r=24, p.<001). The only variables not proving to be significantly related to education were objective measures of the volume of arrests, number of times the officer required discipline, and number of accidents. Interestingly, the benefits of a college education do not become apparent until police officers gain experience. In addition, police, officers with only a high school diploma decreased in overall performance after five years of experience.  相似文献
