The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes. 相似文献

This article explores how nonprofit organizations respond to proposed changes in the relationship between the government and the nonprofit sector using a case study of the “formula funding” controversy at the National Endowment for the Arts (NEA). The article shows how powerful notions of who should get to decide permeate and continually transform the funding debate, making public interest reforms of the process extremely difficult. The author concludes by suggesting that the victories the arts field can claim in defending the current practice of peer panel review at the NEA will turn out to be Pyrrhic victories, ultimately weakening the claim of the nonprofit arts on public resources. 相似文献

Cooperative learning is a structured, systematic instructional technique in which students work together in small groups toward a common goal. We demonstrate the effectiveness of cooperative learning with an illustrative example for teaching the labor supply curve. Recommendations for introducing the technique, forming groups, the instructor's role during group work, grading and extensions of cooperative learning to other topics are discussed. 相似文献

Although teenage parenthood is recognized by many counselors as a developmental identity crisis, it rarely has been viewed as a developmental career crisis. This article suggests developmental career assessment and counseling procedures for use with teenage parents. 相似文献

Adolescent Peer Groups and Social Identity 总被引:3,自引:0,他引:3
Mark Tarrant 《Social Development》2002,11(1):110-123
This study investigated processes by which adolescents form positive evaluations of their peer groups. One‐hundred and fifteen male and female adolescents aged 14–15 years made a series of comparisons between their own peer group (the ingroup) and a group of which they were not a member (the outgroup). In line with the predictions of social identity theory ( Tajfel and Turner, 1979 ), participants behaved consistently in ways which favoured the ingroup: compared to the outgroup, the ingroup was associated to a greater extent with positive characteristics (e.g. being fun, nice, and honest) and to a lesser extent with negative characteristics (e.g. being ignorant, unfriendly, and boring). Their responses were also related to levels of identification with the ingroup: at higher levels of identification participants reported more favourable evaluations of their groups. These findings extend earlier research and show how the benefits derived from group membership in adolescence are in part realised through intergroup processes. 相似文献
