New Media,Micromobilization, and Political Agenda Setting: Crossover Effects in Political Mobilization and Media Usage     

Victor Bekkers  Henri Beunders  Arthur Edwards  Rebecca Moody 《The Information Society》2013,29(4):209-219

In November 2007, Dutch secondary school students revolted against a requirement known as the “1040-hour norm.” New Web technologies, like instant messaging, YouTube, and social networking sites, played an important role in the mobilization effort. In this article, the authors argue that these technologies facilitate a shift toward micromobilization by individuals and small groups. In this “1040-hour norm” case study, the authors analyze how the course of the political agenda-setting process is being transformed through the interplay between processes of meso- and micromobilization, and through new micro-to-mass media crossover effects. When supported by micromedia, the effects of micromobilization can create strategic surprises for traditional intermediary organizations and policymakers.  相似文献   

Document replication strategies for geographically distributed web search engines     

Enver Kayaaslan  B. Barla Cambazoglu  Cevdet Aykanat 《Information processing & management》2013

Large-scale web search engines are composed of multiple data centers that are geographically distant to each other. Typically, a user query is processed in a data center that is geographically close to the origin of the query, over a replica of the entire web index. Compared to a centralized, single-center search engine, this architecture offers lower query response times as the network latencies between the users and data centers are reduced. However, it does not scale well with increasing index sizes and query traffic volumes because queries are evaluated on the entire web index, which has to be replicated and maintained in all data centers. As a remedy to this scalability problem, we propose a document replication framework in which documents are selectively replicated on data centers based on regional user interests. Within this framework, we propose three different document replication strategies, each optimizing a different objective: reducing the potential search quality loss, the average query response time, or the total query workload of the search system. For all three strategies, we consider two alternative types of capacity constraints on index sizes of data centers. Moreover, we investigate the performance impact of query forwarding and result caching. We evaluate our strategies via detailed simulations, using a large query log and a document collection obtained from the Yahoo! web search engine.  相似文献   

SMS in China: A Major Carrier of the Nonofficial Discourse Universe     

Zhou He 《The Information Society》2013,29(3):182-190

As communism loses its tenets as a genuinely believed ideology and becomes a ritualized facet of a regime that strives to prolong and justify its politically and morally shaky mandate, there have emerged two distinct discourse universes in China: the official one and the nonofficial one. Taking advantage of new communication technologies, the nonofficial discourse universe extends its boundaries to such platforms as the Internet and SMS (Short Message Service) messages. This paper examines SMS as a major carrier of the deviant discourse in the following aspects: the development of cell phones from an interpersonal communication technology to a quasi-mass communication channel; the spread of deviant expressions through it; the making of the deviant discourse through SMS; the government's control over SMS; and the role of SMS in increasingly pluralistic political undercurrents in various discourse universes in China.  相似文献

论农地流转中地方政府的角色定位     

邓萍  余春林 《科技广场》2013,(10):187-191

当前在农地流转中地方政府既是监管者,同时又是利益主体,利益冲突之下的政府行为失范使得政府管制不断加强却又失灵。地方政府应定位于自发制度演进的监督者,其职能应以提供公共物品和市场监管为主。同时,地方政府之间也存在地区间的制度竞争。这些都要求地方政府出台综合性的配套制度来促进农地流转。  相似文献
