流光溢彩——谈王家卫电影的光影魅力

光影作为造型语言的重要表现手段,历来受到电影工作者的重视。王家卫电影利用表现性光影塑造出分割、破碎的空间;以光影塑造场景氛围,烘托气氛,表现角色的性格特征和内心情感;运用表现性光影追求唯美的视觉效果和艺术境界。王家卫电影的光影艺术是一种抽象的视觉语言符号,是一种高度抽象化的真实,王家卫的成功尝试拓展了电影的创作空间和表现手法。     

Changing schooling,changing shadow: shapes and functions of juku in Japan

Private supplementary tutoring became a widespread phenomenon in Japan during the 1960s. Since then, institutions providing tutoring known as juku have provided a wide range of services to supplement mainstream education. During decades of development, the shapes and functions of juku have changed in response to changes in schooling. Government attitudes towards juku have also shifted from rejection to collaboration, partly because juku have become so entrenched in Japanese society and can no longer be excluded from public decision-making processes. Collaboration between schools and juku is becoming increasingly evident in a series of neoliberal policy choices and socio-demographic changes. Patterns underline a government move to mobilize profit-driven juku to serve the public good. The inclusion of juku in public schooling necessitates reconceptualization of the roles of juku in the educational landscape. This article presents a conceptual framework based on an overview of the changing relationships between juku and schooling. It also identifies challenges in the collaboration, and explores implications for future relationships between mainstream and shadow education.     

是礼教吃人还是本性吃人——《狂人日记》思想内涵的原型分析

根据荣格的阴影与面具原型理论,《狂人日记》中“吃人”的深层文化心理是对人类劣根性的深刻揭露,“吃人”是阴影原型的显现,是人的本性吃人,不是礼教吃人,“仁义道德”只是社会所发展的集体面具,与吃人是对立的,只不过仁义道德对“吃人”的过分压抑反而使“吃人”现象愈演愈烈。     

论私人财产权的宪法保护

改革开放以来，公民财产权的保护问题日益受到人们的普遍关注。财产权的确认与保护，是公民的一项基本权利，而且是实现其他基本权利的基础。经过近些年的几次修宪，我国现行宪法规定了保护财产权的基本原则，但现有规定仍不能有效调解现实经济生活中的矛盾。所以，应从我国经济不断发展的现实出发，借鉴他国经验，逐步完善宪法对私人财产权的保护。     

一类迭代法的迭代阵谱半径的收敛性分析

在用迭代法求解线性方程组时，迭代矩阵的谱半径的收敛性分析是非常重要的，本文对一类a-严格对角占优矩阵，在一定条件下给出SOR迭代法迭代矩阵的谱半径的上界估计，然后以此为基础，研究SOR的收敛性分析。     

Reliable evaluation method of quality control for compressive strength of concrete

INTRODUCTION In recent years, devastating disasters in whichreinforced concrete structures collapsed have causedmajor loss of life and property damage around thworld. Investigation of these incidents showed thathe collapses were mainly due to the poor concretquality (NCREE, 1999; SECL, 1999; Watabe, 1995)Therefore, high quality assurance in reinforced concrete (RC) structure design and manufacturing is onof the most important safety factors. To promote threliability of structure, co…     

Computation of average run length for residual-based T 2 control chart for multivariate autocorrelated processes

The expression of residual is obtained according to its dynamic response to mean shift,then the distribution of T 2 statistic applied to the residual is derived,thus the probability of the T 2 statistic lying outside the control limit is calculated.The above-mentioned results are substituted into the infinite definition expression of the average run length(ARL),and then the final finite ARL expression is obtained.An example is used to demonstrate the procedures of the proposed method.In the comparative study,eight autocorrelated processes and four different mean shifts are performed,and the ARL values of the proposed method are compared with those obtained by simulation method with 50,000 replications.The accuracy of the proposed method can be illustrated through the comparative results.
