An analysis of corporate environmental responsibility on the global corporate Web sites and their dialogic principles

This study investigated how corporations use their Web sites as a way of helping to build corporate environmental responsibility. A content analysis of 2008 Fortune Global corporate Web sites compared environmental concerns and the use of dialogic principles across three regions (i.e., Asia, Europe, and North America). Results show that about 71% of Web sites have a stand-alone environmental menu as a central location for environmental information, and that Europe is the highest, followed by North America and Asia. The environmental concerns of ‘resources/waste management’ and ‘climate changes’ are more commonly highlighted than are ‘ecosystem’ and ‘environmental governance.’ Furthermore, most Web sites do not fully employ dialogic features, regardless of region.     

"幸福指数"解读与"幸福工程"思考

确立一个科学合理的社会发展指标体系,对引导我国社会科学发展具有重要意义.在深入贯彻落实科学发展观的大背景下,"幸福指数"开始进入各级政府和领导者的决策视野,也引发了社会各界对幸福指数的争论和质疑.本文在充分肯定引入幸福指数必要性的基础上,客观分析目前针对幸福指数的认识偏差和实践误区,从理论与实践的结合上寻找幸福指数对政府施政的指导意义和操作价值.

中国传统科学内在价值的现代审视

古代中国早在秦汉之际就已初步建立起天文、算术、农学和医学四大学科体系,并在不断演进和嬗变中逐渐形成了以生成论自然观为基础和以整体论模型化为特征的科学传统。于众多领域内有着世界性独特贡献的中国传统科学,在自然记录、科学方法与思维取向等层面对当代科技前沿的探索与创新仍然具有极其重要而深刻的借鉴作用和启示意义。对于中国传统科学的内在价值,必须以世界眼光和现代意识加以审视,并通过合理而有效的"互释重构"与"综合创新",使本土思想成为构建创新型国家的鲜活资源。     

Effects of ability mixing in high school on adulthood earnings: quasiexperimental evidence from South Korea

We estimate impacts of ability mixing compared to ability grouping in high school education on students’ adulthood earnings. To overcome endogeneity and selection problems that plagued the previous studies, we exploit a policy experiment in South Korea in the 1970s, which changed the education regime of general high schools from grouping to mixing in major cities. We find that the mixing treatment has a positive but statistically insignificant effect on average adulthood earnings. We also find that while mixing has positive effects on low ability students’ adulthood earnings, it has smaller positive or even negative effects on higher ability students.      

Comparing income poverty gap and deprivation on social acceptance: A mediation model with interpersonal communication and social support

In many developed countries or regions, wide income disparities increase the difficulty in reducing poverty. In their day‐to‐day lives, poor people often feel less accepted by the society. The failures in communicating with social groups and receiving social support lead to negative consequences on individual well‐being and higher level of social exclusion. Based on the debate upon alternative approaches to conceptualizing and operationalizing poverty, this study attempts to verify a mediation model with data from a household survey (N = 1,202) in Hong Kong. The results of structural equation modelling reveal that deprivation is a more powerful indicator than income poverty for specifying the negative relations of poverty with interpersonal communication, social support, and social acceptance; the negative impact of deprivation on social acceptance can be reduced by two significant mediators of interpersonal communication and social support. The results are discussed in terms of directions for future research and policy and welfare intervention.     

The interactive effect of leader–member exchange and electronic communication on employee psychological empowerment and work outcomes

We advance understanding of the role that leaders play in promoting psychological empowerment and positive work outcomes (job satisfaction, organizational commitment and job performance) for employees who engage in a high degree of electronic communication in their job. By integrating leader–member exchange (LMX) theory and theories of electronic communication, we build and test a mediated moderation model in which employees’ degree of electronic communication in their job amplifies the positive relationship that LMX has to psychological empowerment and subsequent employee work outcomes. Based on a sample of 353 early-career professionals employed in a range of different types of organizations, we found general support for the hypothesized model. We discuss the study’s theoretical and practical implications for leading employees in electronically-enabled work environments.     

MEASURING EFFORT INCENTIVES IN A TOURNAMENT WITH MANY PARTICIPANTS: THEORY AND APPLICATION

This article provides an empirical measure to compare incentive effects of different tournament structures. Although there have been many theoretical attempts to analyze incentive effects of a tournament competition, empirical applications are limited as the provided conditions cannot easily be empirically observed. We show that the empirical density of the performance distribution can be used to measure effort incentives in a tournament with many participants. We apply this method to evaluate the grading policy change in the 2008 College Scholastic Ability Test in South Korea. (JEL C70, C51)     

频次效应和阅读理解关系研究

频次效应是二语习得领域近年来的研究热点。实验结果表明,输入频次可以促进阅读成绩的提高,但并不是直线上升;在3次这个最佳练习频次内,受试注意力从大意理解向细节、推理理解转移,受试对反复阅读的积极性和自我效能感逐渐减弱,阅读3次后成绩提高进入停止状态。该实验验证频次效应和阅读理解之间的正面影响,揭示了频次效应的极限所在。实验结果有助于丰富频次效应理论,对阅读教学及学生学业减负可提供参照依据。     

Fast accelerated failure time modeling for case-cohort data

Semiparametric accelerated failure time (AFT) models directly relate the expected failure times to covariates and are a useful alternative to models that work on the hazard function or the survival function. For case-cohort data, much less development has been done with AFT models. In addition to the missing covariates outside of the sub-cohort in controls, challenges from AFT model inferences with full cohort are retained. The regression parameter estimator is hard to compute because the most widely used rank-based estimating equations are not smooth. Further, its variance depends on the unspecified error distribution, and most methods rely on computationally intensive bootstrap to estimate it. We propose fast rank-based inference procedures for AFT models, applying recent methodological advances to the context of case-cohort data. Parameters are estimated with an induced smoothing approach that smooths the estimating functions and facilitates the numerical solution. Variance estimators are obtained through efficient resampling methods for nonsmooth estimating functions that avoids full blown bootstrap. Simulation studies suggest that the recommended procedure provides fast and valid inferences among several competing procedures. Application to a tumor study demonstrates the utility of the proposed method in routine data analysis.
