民生问题是构建和谐社会的关键,也是政府工作的基本着力点。在前期研究构建的指标体系的基础上,运用拉开档次评价法和逐层序关系分析法对我国31个省市自2006-2012年的民生工程建设状况进行了动态综合评价,并用时序几何平均算子(TOWGA)进行了二次加权得到综合评价的总排名,最后对各地区的排序变化进行归纳、分析。 相似文献

Compared to other countries that have suffered from the Nazioccupation, the destructive impact of the Holocaust on theJewish population has been particularly strong in the Netherlands. This paper gives a demographicreconstruction of the Jewish population in the Netherlands by the end of the war (1945),disaggregated by age and sex. The reconstruction is based on two approaches: a forwardprojection 1941–1945, starting from registration data supplemented by information onHolocaust losses; and a backward projection 1966–1945, starting from an enumerationof Halachic Jews carried out in 1966. The two approaches yieldtwo estimates that are comfortingly similar. 相似文献

《中国民办教育促进法》正式审议通过后,由此引发的教育体制滞后现象亟待解决。如何体现该法律中的“尊重”与“公平”意味,如何尽早地使民办学校享受与公立学校同样的“国民待遇”,是包括整个教育界在内的全社会应当极力关注并力促改革的问题。 相似文献

在医学领域中,一种新药投产前,必须确定给人服用的安全剂量和它的毒性大小;有时又需要对两种药的药效进行比较。用均值等效二次单侧检验方法,并对其逐步推广,从而对处理组与对照组进行检验,确定是否等效。逐步等效性t检验也可用在确定仿制药的食用安全区间、比较药效等等。 相似文献

A version of the multiple decsion problem is studied in which the procedure is based only on the current observation and the
previous decision. A necessary and sufficient condition for inconsistency of the stepwise maximum likelihood procedure is
shown to be the boundedness of the likelihood ratios. In the case of consistency the (typically slow) rate of convergence
to zero of the error probabilities is determined. 相似文献

Classification procedures are examined in the case when the dimensionality exceeds the sample size. Two particular suggestions are (i) Principal components analysis and (ii) Two-step discriminant analysis. Comparisons are made in the two sample and the several sample cases. Extensions to growth curve model are investigated using the two stage discriminant analysis. 相似文献

中国农村剩余劳动力数量巨大,如何在城市就业空间有限的情况下有效地解决中国农村剩余劳动力的合理转移问题,是推进城镇化和提升农民收入以及实现社会稳定和可持续发展的重要举措之一。在托达罗人口流动模型的基础上,引入"推拉理论",结合中国农村人口流动实际状况,对托达罗人口流动模型进行修正,并以此构建多元回归模式进行逐步回归分析,结果表明:在农村人口流动的过程中应当加快第二、第三产业的发展,加大培训"农民工"专业技能的力度;深化体制改革,消除城乡二元分割的制度壁垒,构建城乡衔接的社会福利制度;加快工业化和城市化进程,建立城乡统一的劳动力市场,从而进一步促进农村劳动力人口向城镇的有效转移。 相似文献

This article is concerned with how the bootstrap can be applied to study conditional forecast error distributions and construct prediction regions for future observations in periodic time-varying state-space models. We derive, first, an algorithm for assessing the precision of quasi-maximum likelihood estimates of the parameters. As a result, the derived algorithm is exploited for numerically evaluating the conditional forecast accuracy of a periodic time series model expressed in state space form. We propose a method which requires the backward, or reverse-time, representation of the model for assessing conditional forecast errors. Finally, the small sample properties of the proposed procedures will be investigated by some simulation studies. Furthermore, we illustrate the results by applying the proposed method to a real time series. 相似文献

A cornerstone of game theory is backward induction, whereby players reason backward from the end of a game in extensive form to the beginning in order to determine what choices are rational at each stage of play. Truels, or three-person duels, are used to illustrate how the outcome can depend on (1) the evenness/oddness of the number of rounds (the parity problem) and (2) uncertainty about the endpoint of the game (the uncertainty problem). Since there is no known endpoint in the latter case, an extension of the idea of backward induction is used to determine the possible outcomes. The parity problem highlights the lack of robustness of backward induction, but it poses no conflict between foundational principles. On the other hand, two conflicting views of the future underlie the uncertainty problem, depending on whether the number of rounds is bounded (the players invariably shoot from the start) or unbounded (they may all cooperate and never shoot, despite the fact that the truel will end with certainty and therefore be effectively bounded). Some real-life examples, in which destructive behavior sometimes occurred and sometimes did not, are used to illustrate these differences, and some ethical implications of the analysis are discussed. 相似文献
