The limitations of using school league tables to inform school choice

Summary. In England, so-called 'league tables' based on examination results and test scores are published annually, ostensibly to inform parental choice of secondary schools. A crucial limitation of these tables is that the most recent published information is based on the current performance of a cohort of pupils who entered secondary schools several years earlier, whereas for choosing a school it is the future performance of the current cohort that is of interest. We show that there is substantial uncertainty in predicting such future performance and that incorporating this uncertainty leads to a situation where only a handful of schools' future performances can be separated from both the overall mean and from one another with an acceptable degree of precision. This suggests that school league tables, including value-added tables, have very little to offer as guides to school choice.

全球价值链嵌入与技术创新——基于生产分解模型的分析

基于增加值和最终产品的生产分解模型,本文对我国制造业前向与后向产业关联下的全球价值链嵌入进行测度,实证分析全球价值链嵌入对技术创新的作用机理,并在此基础上重点探讨了吸收能力与技术差距两个重要情境因素的调节作用,同时,运用双重差分、工具变量法以及GMM动态面板模型进行稳健性检验,以控制潜在的内生性问题。研究发现:①我国制造业通过嵌入全球价值链的国际间知识溢出效应促进技术创新能力的提升;②吸收能力能够强化这一正向影响关系;③技术差距在后向全球价值链嵌入对技术创新的影响关系中呈倒U 型调节作用,而在前向全球价值链嵌入对技术创新的影响关系中呈正向调节作用。本文推动了网络嵌入理论和知识溢出理论从组织网络向全球价值链领域的繁衍,丰富了全球价值链嵌入领域的研究成果,同时为我国制造业企业在参与国际分工过程中利用全球价值链嵌入实现技术创新能力提升提供重要的理论参考。     

事实、价值与道德选择

在道德选择的理论与实践中,必然遇到事实与价值的关系问题。事实与价值统一于"实际活动着的人"自身。正确的道德选择应建立在价值判断与事实判断统一的基础上,忽视了事实判断作用的道德选择,必然会最终导致对道德价值自身的否定。从人格完善过程的角度来分析,道德选择又是德行与智慧的统一。     

关于含参变量无穷积分的绝对一致收敛的注记

本文从一个反例 ,证明了即使∫∞af(x ,t)dt绝对收敛且一致收敛 ,但不能推出∫∞a |f(x ,t) |dt一致收敛。     

论公司取得自己股份的涵义及价值判断

2006年1月1日生效的新《公司法》对公司取得自己股份制度进行了补充和完善,适应了市场经济发展的需要。然而关于公司取得自己股份的涵义,我国学者并没有统一的界定,而且对该项制度的价值也存在着质疑。对这两个问题进行研究的基础上,构建该制度的基本理论依据。     

试论心理咨询中的价值干预问题

心理咨询过程中"价值中立"是不可能的,价值干预是必要的,也是必需的,进行价值干预应侧重于价值的功能干预,尽量避免价值的内容干预。通过对心理咨询中价值干预问题的探讨,以期对现实的心理咨询活动提供一定的理论指导。     

公共政策价值合法性危机探析

公共政策价值指向是政策科学的元范畴,是理解与研究公共政策的阿基米德点。公共政策作为政治系统的输出,其自身蕴藏着社会共同的善(common good)、正义(公正)和效率三重价值向度和价值指归。然而,日常的政策活动往往隐藏着一定的政策价值合法性危机,作为政策价值危机的降解途径,善治、多中心公众参与和竞争性政策体制不失为降解乃至消解公共政策价值合法性危机的一剂良方。     

电信设备制造商全球价值链升级路径分析——以华为技术有限公司为例

随着经济全球化进程加速,我国电信设备制造商开始国际化进程,嵌入全球价值链及全球价值链下企业升级问题显得尤为重要.华为公司是我国通信制造业国际化的先锋企业,其通过技术创新与研发,向全球电信价值链高端不断攀升,通过向终端转型带动整体价值链链条升级,这使华为公司逐渐成为全球第二大电信设备制造商.对于我国其他设备商来说,华为的成功具有重要借鉴意义.     

Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.
