This article investigates South Korean views on how to deal with the two major security issues regarding North Korea: its nuclear threat and regime instability. In this Special Section, the article analyzes the ongoing debate in South Korea over the government's policy toward North Korea in regard to these two issues. It argues that uncertainties about these two major issues are shaping the regional order in East Asia. In particular, the different levels of cooperation between South Korea and the United States may affect the regional security order in East Asia. In analyzing policy options available to South Korea, the riskiest option would be to employ early preemptive attacks and accelerate the collapse of North Korea given the security dilemma-driven action?reaction in East Asia. Given that the role of China has become the most crucial factor in dealing with North Korea, the most promising strategy would be to reinforce guarantees of extended nuclear deterrence and prompt a soft-landing unification.  相似文献

Youth who participate in service activities differ from those who do not on a number of key demographic characteristics like socio-economic status and other indicators of risk; and most studies demonstrating positive outcomes among service participants employ small non-representative samples. Thus, there is little evidence as to whether the outcomes associated with service participation are similar among students with varying levels of risk. The National Household Education Survey of 1999, a large nationally representative cross-sectional data set that focused on community service, was analyzed to investigate associations between the risk status of 4,306 adolescent students (50.2% female; 63.3% European American, M age?=?15.9), their participation in community service, and their academic adjustment, behavioral problems, and civic knowledge. Because adolescents who participate in service differ from those who do not with respect to demographic characteristics, propensity score analyses were used to correct for potential selection bias in the examination of these relationships. Analyses tested competing theoretical models of service??protective versus compensatory??among students at varying levels of risk, and suggested that service acts as a compensatory factor with respect to academic, behavioral, and civic outcomes. Propensity score analyses revealed patterns suggesting that, in some cases, students with certain demographic profiles that are themselves related to the likelihood of service participation may benefit from service participation more than others. Findings are discussed in terms of their significance for adolescent development, for planning service programs, and for educational policy.  相似文献

We discuss the mechanisms related to quadratic voting, from Vickrey’s counter-speculation mechanism and his second-price auction, through the family of Groves mechanisms and its most notable member, the Clarke mechanism, to the expected externality mechanism, Goeree and Zhang’s mechanism, the Groves–Ledyard mechanism, and the Hylland–Zeckhauser mechanism. We show that each mechanism that involves collective decisions has a quadratic aspect and that all of the mechanisms that we discuss are applications of the fundamental insight that for a process to be efficient, all parties involved must bear the marginal social costs of their actions.  相似文献

The purpose of this study is to evaluate how Toyota managed the recall crisis through surveying public relations experts. By gathering and analyzing the perspectives of public relations (PR) executives and professors toward the Toyota recall crisis, this study tries to evaluate and measure Toyota's public relations strategies for managing the recall crisis. To collecting data, 34 public relations professors and 92 public relations practitioners were interviewed. According to the findings of this study, PR professionals emphasized that Toyota responded poorly (slowly/dishonestly) and lacked communication with the public. With regard to improvements Toyota may work on, PR experts advised not only to resolve internal corporate problems but also to strengthen the relationships with consumers and obligation to investigate further. In regarding with the lessons from the Toyota's crisis, PR professionals highlighted that it is necessary to take anticipated preventative measures and improve investigative duties and preparation for better dealing with crises.  相似文献
