论逆向选择与网络交易的中间化

逆向选择源于信息的不对称。信息不对称会导致严重的后果,它会降低市场交易的效率,严重时会导致市场失灵。与传统交易一样,网络交易中同样存在逆向选择问题,甚至程度更加严重。应对网络交易中的逆向选择需要有其特殊的机制。并从分离均衡、福利促进和声誉转移三个角度分析网络中介在信息不对称的网络交易中的作用,从而为网络交易的中间化提供理论说明。     

关注网络论坛舆论 引导青年网上行为

随着互联网与现实社会的进一步紧密结合,网络论坛已经成为广大青年网民信息交流、观点交流、意识形态交锋的一个重要阵地,规范的网络论坛能够起到及时传播信息、弘扬民族正气、促进社会和谐的作用,无序的网络论坛会引发网络暴力、传播网络谣言、破坏社会的稳定。由于青年是网络活动的主体,因此政府应该有意识、有方法地管理网络论坛,青年工作既要面向现实中的青年,也应面向那些网络上虚拟社区的青年网民,主动引导网络舆论,维护网络道德。     

计算机网络安全技术

随着计算机技术的快速普及和发展,在计算机上处理业务已由传统单机内部网络业务处理、办公自动化等发展到基于企业复杂的内部网、企业外部网、全球互联网的企业级计算机处理系统和世界范围内的信息共享和业务处理.在信息处理能力提高的同时,系统的连结能力也在不断的提高.但在连结信息能力、流通能力提高的同时,基于网络连接的安全问题也日益突出.不论是外部网还是内部网都会安全问题.     

网络诽谤行为的刑事司法认定

网络诽谤行为与传统诽谤行为既有一致性又有新特性,对网络诽谤行为的认定应当谨慎对待。诽谤罪是《刑法》上少数几个亲告罪之一,厘清诽谤行为的罪与非罪、诽谤罪的自诉与公诉的界限,有利于进一步对网络诽谤行为准确的定罪量刑,从而保护公民言论自由,维护网络社会的和谐。     

Ethical and legal issues surrounding academic research into online radicalisation: a UK experience

There is a growing body of evidence that terrorists/terrorist groups have increased their use of the Internet to include a move into online social network environments in their efforts to radicalise and potentially recruit and mobilise new members. Both the US and UK governments acknowledge that not enough is known about this phenomenon and there is an urgent need for more substantive research in the area of terrorists' use of computer-mediated communication. However, research in this area carries with it some serious ethical and legal concerns that cannot and should not be ignored. UK law makes it difficult for terrorism studies researchers and other academics to conduct this online research without potentially violating the law. With careful consideration of the ethical concerns surrounding the methods of data collection, and knowledge of and adherence to Data Protection laws, along with notification of proposed research to the proper law enforcement office to insure compliance with the UK Terrorism Act, it is however possible to move forward with academic integrity and a reasonable assurance that one will not be charged and prosecuted for violations of the Terrorism Acts.     

公安机关处置网络涉警舆情的现实困境与对策研究

涉警舆情处置不但是构建和谐警民关系的重要方式，也是公安机关维护良好形象、为民服务的重要手段。当代公安机关能否利用好这一影响力巨大、动员力极强的舆论工具，能否及时地跟踪好媒体报道的热点问题，能否适时地把握住舆论炒作的焦点所在，已经逐渐成为当代公安机关不可忽视的关键课题。     

从网络性心理障碍看当代大学生心理教育

Understanding Broadcast Political Talk

In June 1989, when Chinese citizens were massacred at Tiananmen Square, and in August 1991, when antireform Communists attempted to lead a coup against Soviet President Mikhail Gorbachev, the American public in unusually high numbers paid attention to the crises; the public s views on policy matters were recorded in public opinion surveys; press coverage of both crises was exhaustive; and elite opinion about U.S. policy was widely aired through the media, exposing the American public to the full spectrum of elite opinion. In both cases elite opinion (voiced in the media and measured through content analysis) was compared with public opinion (measured in public opinion surveys) to test the theories of Walter Lippmann and others that the elites lead public opinion about American foreign policy. In neither case could the dependence of mass opinion on elite opinion be demonstrated. The two bodies of opinion appear to have formed and been expressed in two different, nonoverlapping worlds.     

互联网对社会关系的影响：争议与方向

关于互联网对社会关系影响的研究正在成为学术热点。早期一些学者争论这种行为领域是否能够产生一种通常意义上的持续的人际关系；其次争论的是这种关系是“疏离”还是“延伸”了日常人际关系；以及对关于网络互动所支持的关系属性的研究。系列研究表明，网络互动可以产生具有高度信任、互惠和广泛支持性的人际关系。而这种关系并不必然“疏离”或“延伸”日常关系，其对后者的影响由多种因素综合决定。网络互动倾向于形成弱纽带，但不排斥强纽带的产生。进一步研究可以关注：借助于电脑网络形成的社会关系的动态发展过程、这些社会网络的属性和结构、对社会资本的生产与再生产的影响等等。     

American E-Government at the Crossroads

Abstract

This article reports analyses, findings, conclusions and implications about the first U.S. survey of Web sites of 223 major American cities with populations of 100,000 or more. The national survey sought to provide one of the most comprehensive reviews of, and current and future implications regarding, Web site uses by major cities as well as optimal uses by features and user benefits. It made concrete suggestions for future uses of governmental Web-strategy development. Completed in June 2001, the study sought particularly to evaluate how American cities are incorporating online services into their constituency services. Analyses and findings indicated that many major U.S. cities were advancing their e-gov-ernment initiatives and virtually all cities acknowledged the importance of a basic Web presence. However, a large gap still remained between current practice and Optimal, Ml online potential.
