"人力资本论"中的劳工迁移观分析

二战结束后,随着美国科技革命的展开和经济结构中服务业的崛起,美国从20世纪50年代开始出现了经济繁荣和社会失业率并行攀升的趋势。对此,以西奥德.舒尔茨为代表的经济学家通过实践和潜心研究,提出了颇有影响的人力资本论,其中关于劳工迁移的精辟论述具有很强的历史和现实性价值,但是,其中的局限性也十分突出,尤其是强调区域工资差异的论述似有以偏概全之嫌。无论是在理论上,还是近现代史上的跨国移民以及二战后美国以劳工为核心的人口流动,都证明了该理论中的局限性。

电子商务环境下产品评论特征对消费者信息采纳影响机理的探索

目的/意义基于信息采纳模型和信息系统成功模型,探索了在线产品评论特征对影响消费者信息采纳决策的影响机理。设计/方法通过实验收集数据和偏最小二乘法结构方程（PLS-SEM）来分析数据并验证假设。结论/发现有用度投票对在线产品评论诊断性有正向影响,结构化格式对易用性有正向影响,易用性对在线产品评论诊断性有正向影响,易用性和诊断性对在线产品评论采纳决策存在着正向影响,但认知需求作为调节变量对有用度投票和诊断性的关系及易用性和诊断性的关系影响不显著。     

Can we count on each other? Reciprocity and conflicts in financial support in Sweden

Espvall M, Dellgran P. Can we count on each other? Reciprocity and conflicts in financial support in Sweden
Int J Soc Welfare 2010: 19: 84–94 © 2008 The Author(s), Journal compilation © 2008 Blackwell Publishing Ltd and the International Journal of Social Welfare. This article explores the experiences of reciprocity and conflicts in social relationships, and how these experiences are related to financial support (loans and gifts) in the wider social network. The balance of exchange within the social network as a whole is considered in relation to socio‐demographic features, financial conditions and the availability of social relationships. The data are drawn from a study of financial support exchange in Sweden based on a representative survey among Swedish citizens (n= 500). The results reveal that people living in economic hardship and who have more problematic life circumstances appear to be at risk of receiving more limited informal financial support and experience more feelings of conflict and nonreciprocal social relations.

Three-level main-effects designs exploiting prior information about model uncertainty

To explore the projection efficiency of a design, Tsai, et al [2000. Projective three-level main effects designs robust to model uncertainty. Biometrika 87, 467–475] introduced the Q criterion to compare three-level main-effects designs for quantitative factors that allow the consideration of interactions in addition to main effects. In this paper, we extend their method and focus on the case in which experimenters have some prior knowledge, in advance of running the experiment, about the probabilities of effects being non-negligible. A criterion which incorporates experimenters’ prior beliefs about the importance of each effect is introduced to compare orthogonal, or nearly orthogonal, main effects designs with robustness to interactions as a secondary consideration. We show that this criterion, exploiting prior information about model uncertainty, can lead to more appropriate designs reflecting experimenters’ prior beliefs.     

Proportional reversed hazard rate model and its applications

The purpose of this paper is to study the structure and properties of the proportional reversed hazard rate model (PRHRM) in contrast to the celebrated proportional hazard model (PHM). The monotonicity of the hazard rate and the reversed hazard rate of the model is investigated. Some criteria of aging are presented and the inheritance of the aging notions (of the base distribution) by the PRHRM is studied. Characterizations of the model involving Fisher information are presented and the statistical inference of the parameters is discussed. Finally, it is shown that several members of the proportional reversed hazard rate class have been found to be useful and flexible in real data analysis.     

Censored Kullback-Leibler Information and Goodness-of-Fit Test with Type II Censored Data

The Kulback-Leibler information has been considered for establishing goodness-of-fit test statistics, which have been shown to perform very well (Arizono & Ohta, 1989; Ebrahimi et al., 1992, etc). In this paper, we propose censored Kullback-Leibler information to generalize the discussion of the Kullback-Leibler information to the censored case. Then we establish a goodness-of-fit test statistic based on the censored Kullback-Leibler information with the type 2 censored data, and compare the test statistics with some existing test statistics for the exponential and normal distributions.
