广义G—空间中映象的不动点定理及应用

本文引入广义G—空间的概念,讨论这类空间中映象的不动点的存在性.作为应用,我们得到了概率度量空间中映象的一些不动点定理.本文所得结果,包含引文〔2,3,6〕的一些主要结果作为特例,并在更广泛的情形下回答了或部分地回答了Rhoades〔4〕所提出的问题.     

"赛伯空间"与高校学生思想政治工作

当代大学生在“赛伯空间”中不仅要接受高科技本身的挑战，而且还要不可避免地接受以高科技为载体的“思想病毒”的挑战。新世纪高校思想政治教育工作者必须研究“赛伯空间”，接受挑战。     

浅谈变异修辞的解码

变异修辞拉大了辞面和辞里的距离，创造了广阔的语义空间，具有不确定性和模糊性，受话人在进行解码时，必须根据辞面运用联想才能揭示出所蕴含的深层含义。

Cutting apart together: a diffracted spatial history of an online scholarly relationship

Drawing on the notion of cutting together-apart introduced by Karen Barad and combining it with Lefebvre’s notion of a flaneur (f. flâneuse) who moves between temporal, spatial and political relationships, this article performs a collaboration mediated by social media, namely blogging and tweeting. It draws on the notion of history, space, and social relationships to describe how two women met online. This collaboration as inquiry is about working together despite our differences – finding places to meet rather than diverge, and to dialogue rather than debate. Through a duo-ethnography of how this relationship worked and did not work, notions about how the digital world can act as a mediator for academic work are explored.

Space- and time-efficient approach for virtual machine provisioning

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.
