民主运动、政权框架、知识生产:现代西方政治学形成的历史前提

现代政治学的产生是由于全新社会需要新的政治知识,因此考察现代西方政治学的历史前提,不能不考察这个全新的社会。首先是主权国家和民主政治成为历史潮流,不可阻遏;其次是现代国家政权的确立与维护需要特定的政治知识,从而为政治学提供了研究框架和研究对象;最后现代政治知识生产体制的大规模兴起,为政治学知识生产提供了制度性保障。

Authorization Administration in a Distributed Multi-application Environment

To meet the authorization administration requirements in a distributedcomputer network environment, this paper extends the role-based access control model with multipleapplication dimensions and establishes a new access control model ED-RBAC(Extended Role Based AccessControl Model) for the distributed environment. We propose an extendable hierarchical authorizationassignment framework and design effective role-registeringi role-applying and role-assigningprotocol with symmetric and asymmetric cryptographic systems. The model can be used to simplifyauthorization administration in a distributed environment with multiple applications.
