基于人力资本投资的劳动力迁移模型

劳动力的迁移行为作为人力资本投资的一种形式 ,同样牵涉到成本和收益问题。文章首先介绍了基于人力资本投资的劳动力迁移模型 ,并针对模型列出了模型中存在的问题。在此基础上 ,作者提出模型中应考虑的个体特征 ,同时还综合了到其他学者的研究观点。文章结论是 ,人力资本投资模型的研究仍旧从劳动供给方出发 ,所以它仍属于供给类劳动力迁移模型 ,最终在研究个体劳动力迁移模型中 ,人力资本投资模型可以构成一个有用的组织分析框架。

Social networks and labour market outcomes in a meritocracy

This paper examines the significance of personal contacts in job searches, in the context of Singapore's meritocratic system. I show that in certain sectors, such as the state bureaucracy, social networking brings no distinct advantages as appointments are made exclusively on the basis of the academic credentials of the candidates. Thus, personal contacts are not always useful, especially in labour markets that rely heavily on the signalling role of academic credentials to match persons to jobs and allocate rewards. In contrast, personal contacts are more useful among less qualified job searchers in the private sector.     

Did PRWORA's mandatory school attendance policy increase attendance among targeted teenage girls?

The purpose of this paper was to examine if the school-attendance requirement of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) significantly increased attendance among the teenage girls that the policy targeted. This study applied difference-in-difference and difference-in-difference-in-difference methods to 12 years of cross-sectional data from the October Supplement of the Current Population Survey while isolating the effects of PRWORA from the effects of other factors that might have influenced the target population's school attendance. The findings indicated that PRWORA, overall, did not have significant positive impacts on school attendance; rather, the policy was associated with a small but significant reduction in school attendance of U.S.-born disadvantaged teenage girls between 1996 through 1999 and essentially no effects on the target population thereafter.     

基于DSP与LabVIEW仿生运动机理模型在线切换、离散化系统

仿生运动机理模型在实际的应用过程中,必须针对特定的应用场合和不同的硬件系统选择不同的控制模型和最优参数,使实际效果达到最佳。文章提出了一种基于DSP与LabVIEW,对仿生运动机理模型进行实时在线离散化的方法。该方法实现了控制模型的在线切换、参数的实时修正、模型的在线离散化、LabVIEW和DSP的实时通信。实验结果表明,该系统实时性好、运行可靠。

The Competitive Impact of Targeted Television Advertisements Using DVR Technology

Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace.
