不完备信息系统的矩阵约简算法

粗糙集理论是用来解决不确定性的新的数学工具，而知识约简是粗糙集理论中一个重要的研究课题。J．W．Guan等提出了信息系统下的矩阵算法。章则是进一步讨论不完备信息表下的矩阵约简算法，实例表明该算法是有效的，具有一定的应用价值。     

从台湾社会意识看"一国两制"的心理基础

台湾社会意识包括中国意识、台湾意识、疏离意识三个层次,与此相适应,在两岸关系问题上既盼望祖国统一、又希望维持现状是台湾人民的普遍心态。“一国两制、和平统一”的方针,既符合台湾人民统一的愿望,又符合台湾人民维持现状的要求,是易于被台湾人民所接受的最佳统一方案。随着两岸交流的加深,台湾人民必将了解和接受“一国两制”。

远程教育的时间观--从人类学的观点看

通过梳理时间概念的历史,以及借鉴教育人类学对时间问题的研究成果,可以得出这样的结论：远程教育利用其媒体技术创造了一种可以称作为“虚时间”的新的时间形态,这使得远程教育在克服时间距离方面出现了可能,但同时也在师生沟通方面增加了其他难度,

Common legacy,different paths: the transformation of educational systems in the Czech Republic,Slovakia, Hungary and Poland

The goal of this work is to better understand the institutional changes in the educational systems of the Czech Republic, Hungary, Poland and Slovakia. We demonstrate that the educational reforms implemented during the transformation introduced very different institutional arrangements in the four countries, despite the fact that their systems shared many common characteristics at the beginning of the 1990s. Differences between the national approaches to educational reforms are particularly reflected in the modes of education decentralisation, the level of school autonomy, accountability and funding mechanisms. We believe that different institutional arrangements may have contributed to the divergent achievements of the Czech Republic, Slovakia, Hungary and Poland in the PISA programme.     

Super-proximity routing in structured peer-to-peer overlay networks

Peer-to-Peer systems are emerging as one of the most popular Internet applications. Structured Peer-to-Peer overlay networks use identifier based routing algorithms to allow robustness, load balancing, and distributed lookup needed in this environment. However, identifier based routing that is independent of Internet topology tends to be of low efficiency. Aimed at improving the routing efficiency, the super-proximity routing algorithms presented in this paper combine Internet topology and overlay routing table in choosing the next hop. Experimental results showed that the algorithms greatly improve the efficiency of Peer-to-Peer routing.     

论邓小平人力资本思想的形成及时代特征

邓小平理论中蕴含着丰富的人力资本思想,这些思想的产生,有其深刻的理论渊源和特殊的时代背景:马克思人力资本理论是其理论基础,中国改革开放和社会主义现代化建设的伟大实践是其产生的实践要求,西方人力资本理论的发展和完善与之相互策应,中华民族五千年思贤辩才的文化积淀是其历史渊源,新科技革命是其时代背景,而自身传奇的经历和超凡的素质是内在的决定因素。
