"被缚"的女人--浅析《荷马史诗》中的女人群像

《荷马史诗》(包括《伊利亚特》和《奥德赛》)是西方多种文学传统的源头。这部人类童年时代的作品一开始就显露这样的端倪:女人是不自由的,女人的“被缚”了。女人的“被缚”可分多种情形,它有着深刻的社会根源。“被缚”女人的塑造对后世文学有着很大的影响。

A study of uniformity pattern for extended designs

The objective of this paper is to investigate the issue of projection discrepancy for extended U-type or nearly U-type extended designs along the line of Fang and Qin (2005 Fang, K. T., and H. Qin. 2005. Uniformity pattern and related criteria for two-level factorials. Science China Series A 48:1–11.[Crossref] , [Google Scholar]) based on the centered L₂-discrepancy proposed in Hickernell (1998 Hickernell, F. J. 1998. A generalized discrepancy and quadrature error bound. Mathematics of Computation 67:299–322.[Crossref], [Web of Science ®] , [Google Scholar]). Extended designs are obtained through augmenting optimally few runs (or points) to an optimal U-type design. Lower bounds to projection discrepancy with reference to the centered L₂-discrepancy of extended designs have been obtained. Some illustrative examples are also provided.     

Minimum projection uniformity for computer experiment with quantitative factors

Computer experiments involving quantitative factors at high levels are becoming more and more important in the study of complex experiments arising in the area of science and engineering. Uniform designs are found to be widely applicable in computer experiments in the form of space-filling designs. In this paper, the projection uniformity for quantitative designs is studied under wrap-around $L_2$-discrepancy. A lower bound of uniformity pattern for general asymmetric designs is provided, which can be used to serve as a benchmark for both comparing different designs and also to determine the optimal design. As a byproduct, a lower bound of wrap-around $L_2$-discrepancy measure for the asymmetric design is also obtained. Some illustrative examples and numerical comparisons are also provided for supporting our theoretical results.

为西部大开发的战略实施营造良好法制环境

西部大开发战略的实施,需要良好的法制环境。法律机关应广泛开展法制宣传工作,提高西部群众法律意识;加强地方立法,进一步完善法律法规;严格执法,推进“依法治国”进程,为西部大开发营造良好法制环境。     

湛若水心学视域下的易学观

湛若水哲学体系的构建与易学密切相关。在阐释心学思想时，湛若水借鉴《周易》经传的思想，创造性诠释了《系辞》、乾卦、复卦，构建一套以“知几”为核心的修养工夫论。“心之体即是易体，心之几即是爻变”为湛氏易学思想的总纲，该理念高度概括了心与易通一不二的关系，积极推动了明代中晚期心学易思潮的发展。
