网络安全分析

网络安全对于国家安全和经济建设具有重要意义 ,但网络面临着种种威胁。我们有必要通过分析网络安全技术 ,给出一个较完备的网络安全体系。     

入世后信息网络监察工作面临的形势和对策

计算机网络技术的迅速发展,使计算机网络监察工作面临新的形势和特点。因此,信息网络监察部门应加强立法建设;加强网络监察技术手段和装备的建设;加强反计算机网络犯罪机构的工作力度,加快建设一支高素质的网络警察队伍;落实好网络安全保护责任制;加强网民的守法意识和防范能力;建立健全国际合作体系。     

基于网络媒介的突发性公共危机信息传播仿真和管理对策研究

危机信息的健康传播在突发性公共危机管理中至关重要。为了研究突发性公共危机信息在网络环境中传播的特征,本文以复杂适应系统理论为指导,利用多主体建模方法,基于Repast平台模拟突发性公共危机信息在网络媒介中的传播过程。通过模型仿真我们发现突发性公共危机在网络环境中传播的生命周期现象和群极化现象;并且分析比较了各主体属性在不同参数值下的演化结果,探寻危机信息传播的有效方法,为政府如何应对危机管理提供决策支持,以期有效控制突发性公共危机信息在网络环境的恶性传播。     

Humanitarian interventions and the media: broadcasting against ethnic hate

Humanitarian interventions routinely come with media components, because of the media’s assumed ability to counter hate and support reconciliation. Radio programmes for peace should enable audiences to withstand manipulation and react non-violently in conflict situations. Based in the ideological tradition of modernisation theory, these programmes assume that violent conflict can be overcome by educating individuals. Based on original data from South Sudan, this paper argues that social structure and duty to leaders play a bigger role and that present media interventions are ill suited to the problem. Interventions need to be tailored to the situation instead of relying on generalised responses.     

Self-protection in Greece: sticking with groups,communicating, protesting,and fighting

Despite the international community’s responsibility to protect (R2P) mandate, we are years away from effective international enforcement mechanisms. It is therefore important that we better understand and seek to support local capacities for self-protection. Migrants and refugees in Greece have shown us four central ways they cope with insecure environments. They stick together in groups, communicate warnings of danger, protest when conditions are threatening, and fight when all else fails. This practical note offers three recommendations on how to support the capacity of displaced people to protect themselves.     

The Political Significance of Social Media Activity and Social Networks

This paper examines panel data from two waves of the Youth Participatory Politics Survey, a nationally representative sample of young people in the United States. It employs a cross-lagged design to investigate the extent to which common forms of online activity create pathways to online and offline forms of political activity. Specifically, we examine the influence of Friendship-Driven (FD) and Interest-Driven (ID) online activity on online participatory politics and on offline forms of political action. Our findings reveal that FD and ID activity relate to political engagement, but in different ways. In addition, we find that the size of young people’s social networks interacts with both FD and ID online activity to promote political activity. This indicates that having exposure to “weak-ties” (resulting from large social networks) promote higher levels of political engagement. These findings demonstrate the need to specify the kinds of online activities in which youth are engaged and, more broadly, the political significance of social media and social networks     

The Theory of International Media Diffusion: Political Socialization and International Media in Transitional Democracies

Despite the long-standing normative assumption that, for individuals in transitional states, exposure to Western media cultivates stronger attachments to Western political and economic values, the evidence presented here suggests otherwise. Using mass public survey data from the mid-1990s in five Central and Eastern European countries, this article demonstrates a general lack of support for international media’s positive contributions to individuals’ democratic attitudes and preferences for market economies. This finding is particularly unexpected because the countries under investigation represent ideal cases based on their proximity to Western democracies and international (Western) media sources’ capacities for extensive transnational media penetration into the region. Yet this failure to find persuasive evidence of the influence of international media diffusion on the development of Western political values sharpens our understanding of the process of political socialization in democratizing countries by eliminating an assumed source and is thus relevant to students of democratization, international development, and mass media.

Tourism,Development, and Media

Tourism has long figured in municipal and state-wide plans for economic development and revitalization. Such plans often articulate themes subsequently used to organize tours, advertising campaigns, and merchandising. In the 1990s, some residents of Roswell, New Mexico, tried to build tourism using typical southwestern themes. Others capitalized on Roswell’s unique association with an alleged crash of an extraterrestrial craft. Early support from the New Mexico Tourism Department (NMTD) facilitated the success of Roswell’s UFO-based tourism. In 2007, NMTD launched its own alien-based advertising campaign promoting New Mexico as a tourist destination.

基于作者共被引的公共行政研究状况图谱分析——以《Public Administration Review》为研究对象

一门学科的发展离不开优秀专家学者的倾力支持，在公共行政学的形成和发展过程中，同样有一批优秀的公共行政学者推动了公共行政不同分支领域的衍生与发展。运用作者共被引和信息可视化方法，对权威期刊《公共行政评论》（Public Administration Review）于1975--2008年间发表的论文引文中被引频次前50名的学者进行分析。研究结果展现了公共行政领域的主要学术流派，并验证了公共行政研究确实是在沿着范式转移的轨迹更迭交替着。而这种变迁是相对的，大部分时间内，不同范式之间以及和其他学术流派之间是共存、互动甚至交融的。研究还发现，网络化治理正凭借其多中心和网络化的组织基础以及服务治理的先进理念迅速崛起，它将成为公共行政新的研究范式，而基于网络理论的公共行政理论大整合也将很有可能成为公共行政未来的研究热点。此外，实证结果与公共行政范式分类的高度相似性也充分表明了作者共被引和信息可视化方法的科学和有效，它的确为学科范式研究提供了一条定量研究的新思路和一个宏观分析的新视角。
