日本高等教育机会不均等问题探析

教育机会均等是探讨教育问题的重要概念之一。战后日本为实现其高等教育机会均等颁布实施了诸多政策，为消除各种高等教育机会的差异问题做了很大努力。近来从日本先行研究结果来看，多表明各收入阶层间的教育机会差距在缩小，然而也出现了高等教育机会差距在扩大的研究结果，结论并不一致。文章从战后日本的高等教育政策入手，通过关于高等教育机会分布的阶层间差别和地区间差别的研究结果，分析日本高等教育机会的不均等问题，并探求其原因。     

Equity, efficiency and inequality traps: A research agenda

This paper discusses a research agenda that arises from unanswered questions and unresolved issues considered in the World Bank’s World Development Report 2006: Equity and Development. After formalizing the key concepts of equity; equality of opportunity; and efficiency, and proposing a definition for an equitable development policy, the paper discusses the concept of inequality traps, around which the research agenda is structured. Four broad groups of research questions are highlighted: those revolving around the measurement of inequality of opportunity and the diagnostics for the existence of an inequality trap; those dealing with the causes of inequality traps; the quantification of their efficiency costs; and those related to how institutions (including governments) evolve to overcome inequality traps. Bourguignon and Ferreira are in the Development Economics Vice-Presidency, The World Bank. Michael Walton is at the John F. Kennedy School of Government, Harvard University. Together, they led the team that produced the World Bank’s World Development Report 2006: Equity and Development.     

论大学生智力投资教育的创新

要提高思想政治工作的效果,就必须创新教育内容和教育形式。在大学生中开展“智力投资教育活动”就是一种创新教育,它让大学生联系自己的实际计算其本人的“智力投资额”,从而以真情回报父母、回报国家、回报社会,增强自身的社会责任感。     

创业警觉性与创业机会的匹配研究

研究了创业警觉性和创业机会之间的匹配关系,指出创业警觉性和创业机会的匹配是机会发现的必要而非充分条件。创业警觉性与创业机会之间不仅需要实现强度与方向2个属性维度的匹配,而且要考虑动态性的匹配,其条件是在机会之窗从开启到关闭的期间内,随机出现的机会点必须落在创业警觉性区域之内。     

Gangs,clubs, and alcohol: The effect of organizational membership on adolescent drinking behavior

How does adolescent organizational membership in general, and simultaneous membership in distinct types of organizations in particular, impact drinking behavior? While past studies have focused either on the learning effect of involvement with gangs or on the constraining influence of conventional organizations on adolescent problem behavior, we explore the possibility that conventional school clubs can serve as socializing opportunities for existing gang members to engage in drinking behavior with non-gang club members. Using the Add Health data, we show that gang members drink more often, and engage in more binge drinking, than non-members. More importantly, individuals who are members of both gangs and school clubs drink alcohol at greater levels than those who are solely involved in gangs. In addition, non-gang adolescents who are co-members with gang members in the same school club are more likely to drink alcohol than non-members. This result has important implications for understanding the role of organizations in adolescent behavior and suggests that the study of delinquent behaviors would benefit from devoting more attention to individuals who bridge distinct types of organizations.     

电子商务企业：金融危机下的生存与机遇

Partial Correlation in Terms of Path Coefficients

The distribution of members of the American Statistical Association (ASA) by several demographic and professional measures is characterized. The analysis is based on a 1979 survey of ASA members who resided in the U.S. More detailed analysis focuses on how demographic and professional characteristics affect the distribution of income and the odds of participating in ASA activities. Several interesting observations are made. Years of experience since highest degree is the most important predictor of income. Highest degree and whether employed in academia are also important. There is a significant difference between the distribution of income for men and women; although the difference is insignificant at one year of experience, it increases with the experience level. Although the survey represented a 100% sample of blacks, Hispanics, and native Americans in the ASA, there is insufficient data to formulate a detailed model of income for this minority group; its average income, however, falls below the expected income of the majority population for higher experience levels. For both the odds of attending annual meetings and serving ASA as an officer or committee member, the most important discriminator is the highest degree of the member. Race is also a significant factor: blacks, Hispanics, and native Americans were least likely to attend annual meetings, and Asians and Pacific Islanders were least likely to hold office. Years of experience is important also for predicting the odds of having held office but not of having attended meetings.     

An alternative approach to reliability analysis of cold standby systems

ABSTRACT

An alternative approach is applied for reliability analysis of standby systems on the basis of matrix renewal function. In this regard, a single-server, two identical unit cold standby systems with an imperfect switch is considered as a three-state semi-Markov process. Several important reliability measures such as availability, mean time to failure, expected number of failures, etc., are obtained for general lifetime distributions. Also, the main results have been treated to the case of exponential lifetimes and explicit formulas obtained for this case in addition of some numerical illustrations. This approach can easily be extended to more general standby systems with different configurations.     

私营经济的新机遇与挑战

党的十五大给私营经济的发展提供了前所未有的机遇，私营经济社会地位发生了明显的变化，允许公有制多种实现形式，及国有企业逐步退出一些竞争性行业，为私营经济的发展开拓了更广阔的空间。但是，要使私营经济成为经济发展的新的增长点，发挥更大的作用，还需解决资金紧、法律法规不健全、宏观调控缺乏、企业财务混乱、管理落后、生产经营行为的短期性等问题
