事实、价值与道德选择   总被引:1,自引:1,他引:0  
王敬华 《齐鲁学刊》2007,(6):134-137
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。  相似文献

Whereas period life expectancy constitutes an intuitive indicator of the survival conditions prevailing at a particular period, this paper argues that, given the existence of welfare interdependencies, that widespread indicator is nonetheless an incomplete measure of the longevity achievements relevant for human well-being. The central importance of coexistence for human-beings implies that usual life expectancy measures should be complemented by joint life expectancy indicators, which measure the average coexistence time under particular survival conditions. After a study of the theoretical foundations of ‘single’ and ‘joint’ life expectancy indicators, it is shown that joint life expectancy measures tend to enrich significantly the comparison of longevity achievements across countries and periods. Moreover, the introduction of joint life expectancy indicators—as a complement to conventional life expectancy measures—into multi-variable indexes such as the United Nations’ HDI is also shown to affect international rankings of standards of living to a non negligible extent.

In survey research, it is assumed that reported response by the individual is correct. However, given the issues of prestige bias, self-respect, respondent's reported data often produces estimated values which are highly deviated from the true values. This causes measurement error (ME) to be present in the sample estimates. In this article, the estimation of population mean in the presence of measurement error using information on a single auxiliary variable is studied. A generalized estimator of population mean is proposed. The class of estimators is obtained by using some conventional and non-conventional measures. Simulation and numerical study is also conducted to assess the performance of estimators in the presence and absence of measurement error.  相似文献

In many practical applications, high-dimensional regression analyses have to take into account measurement error in the covariates. It is thus necessary to extend regularization methods, that can handle the situation where the number of covariates p largely exceed the sample size n, to the case in which covariates are also mismeasured. A variety of methods are available in this context, but many of them rely on knowledge about the measurement error and the structure of its covariance matrix. In this paper, we set the goal to compare some of these methods, focusing on situations relevant for practical applications. In particular, we will evaluate these methods in setups in which the measurement error distribution and dependence structure are not known and have to be estimated from data. Our focus is on variable selection, and the evaluation is based on extensive simulations.  相似文献

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。  相似文献

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。  相似文献

公共政策价值合法性危机探析   总被引:1,自引:0,他引:1  
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。  相似文献

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.  相似文献
