详细分析了UMTS认证和密钥分配协议的过程以及协议的安全性，找出协议中存在的弱点和可能的攻击，提出了公钥加密协议的改进方法。经过分析，这一改进协议不但能满足第三代移动通信的安全需求，而且改善了UMTS在认证过程中在安全上的不足。     

Self-Organized Public-Key Management for Mobile Ad Hoc Networks Based on a Bidirectional Trust Model

In traditional networks , the authentication is performed by certificate authoritys（CA）,which can＇t be built in distributed mobile Ad Hoc Networks however. In this pa per, we propose a fully self-organized public key management based on bidirectional trust model without any centralized authority that allows users to generate their public-private key pairs, to issue certificates, and the trust relation spreads rationally according to the truly human relations. In contrast with the traditional self-organized public-key management, the average certificates paths get more short, the authentication passing rate gets more high and the most important is that the bidirectional trust based model satisfys the trust re quirement of hosts better.     

国际私法中法律规避的定性问题

法律规避究竟是国际私法中的一项独立的制度，还是公共秩序保留制度的一部分？这个问题一直困扰理论界。法律规避作为国际私法的一项独立的制度，从实践层面讲，存在着意图认定上的主观性、效力认定上的矛盾性和处理后果上的消极性等缺陷；如果看作是公共秩序保留制度的一部分，不仅可以解决实践中的缺陷，从理论上讲也具有合理性。在我国国际私法立法中，法律规避没有独立存在的空间。

论区域公共品及其提供主体

区域公共品具有消费上的非排他性和非竞争性，有明显的空间性、地点性和规模大的特点。区域公共品由私人、区域内的独立行政区或中央政府来提供都不合适，其应当是整个经济区。当整个区域不是一个独立行政区时，必须有一种制度保证整个区域来提供。

When Research and Practice Collide: The Role of Action Research When There Is a Conflict of Interest with Stakeholders

This article discusses problematic aspects of the role of the action researcher when working with multiple stakeholders on a complex research project concerning regional development. The case presented here deals with the improvement of the regional innovation system in a small region in the south of Norway. The project resulted in a conflict between stakeholders and the action research (AR) team. We claim that when working in a regional context, the role of the action researcher is set to be a collaborator in a context of power play; the ultimate stakeholders must be defined as the citizens in that region. Therefore, in some situations the action researcher must have a legitimatised right to abandon collaboration and present a critical voice in the public deliberation. Strategic power play and strategic action by stakeholders represent a clear threat to the soft approach of collaboration, reflectivity, and democratic dialogue that AR represents. The ultimate challenge and obligation of the action researcher is to improve democracy in society in a long-term perspective through representing a critical capacity in the public deliberation.
