It is simply impossible to know all about the world by one’s own experience. Therefore, the media have an important role to play in informing people about events that occur and the interpretation of these events. However, people do not have to pay attention to this information. There is a significant difference between people’s interest in a topic and following it in the media. Given the import...

We develop a model of how information flows into a market, and derive algorithms for au­ tomatically detecting and explaining relevant events. We analyze data from twenty-two "political stock markets" (i.e., betting mar­ kets on political outcomes) on the Iowa Elec­ tronic Market (IEM). We prove that, under certain efficiency assumptions, prices in such betting markets will on average approach ...

However, the conclusions and opinions about the role of Social Networking Sites in modern revolutions remained co...

Standard interpretations of the history of public health in New York City in the twentieth century describe either the decline or the growth of the importance accorded to public health activities. To the contrary, public health has, paradoxically, both declined in salience and attracted increasing resources.

As the editors of the volume The Social Movement Society put it, ‘‘although disruption appears to be the most effective political t...

While predictions based on social media are not representative of the voting popul...

A BSTRACT We propose a context-dependent approach to the study of political information. Combining a content analysis of broadcast news with a national survey measuring public awareness of various events, issues, and individuals in the news, we show that properties of national media systems influence both the supply of news and citizens’ awareness of events in the news. Public service-oriented ...

Analyzing international political behavior based on similar precedent circumstances is one of the basic techniques that policymakers use to monitor and assess current situations. Our goal is to investigate how to analyze geopolitical conflicts as sequences of events and to determine what probabilistic models are suitable to perform these analyses. In this paper, we evaluate the performance of N...
