二维随机裂纹介质模型

利用随机过程的谱展开理论及Hudson的裂纹介质模型构造一种裂纹数密度具有空间统计分布的随机介质模型的理论。利用Hudson理论的裂纹的微观参数(裂纹数密度)与裂纹介质的宏观性质(弹性常数)相联系的特点,模拟了二维指数型椭圆型随机介质。结果表明模型将裂纹的微观参数与裂纹介质的宏观性质直接联系起来,并且裂纹数密度对随机裂纹介质的各个弹性常数有不同程度的影响。     

新媒介：当代大学生思想政治教育的有效途径

随着信息技术的迅猛发展,新媒介对大学生的影响日益深刻。新媒介具有对大学生进行思想政治教育的先天优势,但新媒介环境下的思想政治教育危机也不容忽视。我们应当扬长避短,积极探索利用新媒介开展思想政治教育的新路径,不断提高思想政治教育的针对性和有效性。     

新时期公安边防部队涉警舆情应对研究

随着现代信息技术的发展以及互联网的普及,社会舆论载体日益增多,而公安工作的特殊性又使公安机关极易成为社会关注的焦点。广泛、动态的涉警舆论一方面促进了公安边防工作的有效开展,但另一方面也给公安边防部队及公安边防工作带来巨大挑战。密切掌握涉警舆情动态,切实提高公安边防部队应对负面涉警舆情的能力,是公安边防部队履行三大历史使命的保证。     

Bernard Fall and Vietnamese Revolutionary Warfare in Indochina

This article assesses Bernard Fall’s concept of Vietnamese Revolutionary Warfare in Indochina between 1953 and 1958. It also investigates differences in the conceptualization of Revolutionary Warfare between Fall and proponents of French military doctrine known as la guerre révolutionnaire. The last component of the article considers limits of Fall’s influence on counterinsurgency doctrine.     

层次化新闻视频处理框架的设计与实现

提出了一个通用的层次化新闻视频处理框架,将新闻视频处理分为句法分段、语义标注以及视频摘要三个层次,并给出了三个层次中涉及的故事单元探测、字幕探测、视频摘要等关键技术的解决方案。框架突破了传统的新闻视频处理框架仅局限于句法分段以及单媒体特征进行处理的缺陷,通过对视音频特征进行多模态的综合分析来获取新闻视频高层的语义内容。实验通过一个新闻视频处理原型系统NVPS验证了框架的可行性,重点对故事单元探测、标题探测以及口播帧探测三个算法进行了实验,实验结果分别达到88%,86%和86%的探测准确率,从而进一步证实了层次框架在新闻视频处理方面的有效性。     

传播学视野下的外国新闻事业史课程教学

外国新闻事业史课程的教学一直存在资料冗杂、线索不清、史多于论等诸多问题,如何更好地解决这些问题一直困扰着教学实践。笔者从传播学的一些经典理论出发来对这些问题进行具体分析,从而得出需要精简教学内容、提炼基本规律、增加课外拓展等有效地解决办法,最终达到提高外国新闻事业史课程教学效果的目标。

A Rejoinder to Peter M. Sales

This analytical article asks the question: to what degree did the media contribute to the Rwandan genocide and what might have been done about it? In examining the historical development of mass media in Rwanda, this paper argues that while hate media clearly contributed to the dynamics that led to genocide, its role should not be overstated. While it is commonly believed that hate media was a major cause of the genocide, instead it was a part of a larger social process. The use of violent discourse was at least as important as, for example, the availability of weapons in carrying out the genocide. Put another way, violent discourse was necessary but not sufficient by itself to cause the genocide of 1994. In arguing this thesis, Rwandan history is examined to demonstrate the processes of communication in the formation of destructive attitudes and behaviour. Next, analysis of the methods and content of propaganda campaigns is discussed. Finally, an overview of the requirements and organizations for third parties to conduct international communication interventions is presented in the last section.     

Unraveling the violence in Kazakhstan

There were several high-profile violent incidents in 2011 in Kazakhstan, including several bombings, shootings that targeted police, and a protest turned clash that resulted in a number of deaths. Some of the perpetrators reportedly had links with radical religious groups. An overlooked aspect of the violence is how it is reported in Kazakhstan. There are active, competent media in Kazakhstan, which are largely unknown in the West. An examination of these incidents using the media in Kazakhstan can provide a unique insight into what took place. While Western sources quickly blamed radical religious groups with international connections, media in Kazakhstan have found that there are other reasons for the violence.
