女性的想象与现实:中港跨境一夫多妻关系

通过对香港男性北上“包二奶”行为的调查 ,审视了当代婚姻及家庭的观念的维持与变异。与一般论述以男性角色为讨论中心不同 ,本研究突出女性在这个关系里面的主体性 ,通过香港和内地妇女自己的说话 ,探讨女性如何参与制造“包二奶”这个想象并构建为他们生活中的现实 ;这种主体之间的互动 ,又如何为延续父权的社会文化制度提供有利条件     

THE GEOMETRIC PROPERTIES OF THE SET OF LYAPUNOV MATRICES AND THE STABILITY OF THE MATRIX FAMILY

Given a stable matrix A∈C~(n×n),there are some simple simultaneous inequalities whosecoefficients rely on A.For (?)P~H=P∈C~(n×n),if P satisfies these inequlities,then PA A~HP<0.As anapplication of the main results,the stability of the matrix family is treated.Besides,some geometricproperties of the set of all the Lyapunov matrices of a given stable matrix are considered.     

论《西厢记》人物关系中择婚理念之冲突

在崔莺莺、张生和郑恒之间,存在着一个三角关系。历来人们认为崔郑是“门当户对”的,而本文认为崔张才更加“门当户对”,崔莺莺是已故相国之女,张生亦是已故礼部尚书之后。他们的爱情之所以受到阻挠．则是由世俗的、伦理的、家族的等各种原因造成的。     

Occludin binds to the SH3-hinge-GuK unit of zonula occludens protein 1: potential mechanism of tight junction regulation

The interaction between tight junction proteins occludin and zona occludens protein 1 (ZO-1) was clarified. The sequence cc1 within the hinge region of ZO-1, connecting its SH3 and GuK domains, was identified as a new association site for the occludin C-terminus, core binding area GLRSSKRNLRKSR (mouse ZO-1^606-618). Occludin also bound to the sequence H2 within GuK, core area HKLRKNNH (ZO-1^759-766). In occludin, the binding core was ELSRLDKELDDYREESEEY (mouse occludin^455-473). Helicity of the sequences was suggested by circular dichroism. Because basic residues in ZO-1, acidic residues in occludin (underlined), coiled-coil helix-forming leucine heptad motifs (bold) in occludin and, probably, in cc1 were essential, we conclude that interactions were both helical and ionic. Moreover, the GuK domain bound other GuK molecules, suggesting oligomerization of ZO-1. Generally, the assumption is supported that the SH3-hinge-GuK region represents a functional and regulatory unit in ZO-1 forming a multiprotein tight junction complex with occludin.Received 12 January 2004; received after revision 23 February 2004; accepted 31 March 2004     

Hcc-1 is a novel component of the nuclear matrix with growth inhibitory function

Hcc-1 is a novel nuclear protein containing the SAF-box DNA-binding domain. It binds to both double-stranded and single-stranded DNA with higher affinity for the single-stranded form. In addition, it also binds specifically to scaffold/matrix attachment region DNA. These nucleic acid-binding characteristics suggest a potential function for Hcc-1 as a component of the heterogeneous ribonucleoprotein complex. Using a yeast two-hybrid screen, two DEAD-box RNA helicases, BAT1 and DDX39, were identified as proteins that interact with Hcc-1. Interactions with these RNA helicases suggested a role for Hcc-1 in nucleic acid biogenesis. Expression of Hcc-1 in the HEK293 cell line resulted in a slower growth rate compared to controls (p = 0.0173) and an accumulation of cells at the G2/M phase (p = 0.0276 compared to control HEK293 cells). Taken together, these results suggest a role for Hcc-1 in growth regulation and nucleic acids metabolism.Received 13 May 2004; received after revision 30 June 2004; accepted 6 July 2004     

面向产品族模块化设计和制造的工艺聚类分析方法

为了实现产品族模块化制造,必须综合考虑设计和制造两方面的因素.利用零部件与工艺路线之间的关联,形成了基于聚类分析的产品族模块化设计和制造的方法.通过分析产品族内各成员构成比例及零部件的变形组合,建立了产品族结构模型;在各零部件工艺路线串比较的基础上,构建零部件关联矩阵;采用聚类分析法对零部件进行聚类划分,得到了具有相似工艺路线的零部件聚集;通过分析模块内各零部件对应的各工艺环节任务量的分配比例,实现了与设计模块对应的制造单元的规划.由于考虑了各成员的构成比例,具有对变化的用户订单响应能力.     

传统家训与传统文化关系探析

一类解析函数族的正规性

研究解析函数族的正规性问题，得到：设F为区域D内的解析函数族，n≥2为任一正整数，a≠0，＊，b≠∞为常数；如巢对F中任意2个函数f与g,f＇-af^n与g’-ag^n在D内都以b为公共值，则F在D内正规．当n=1时此结果不成立．
