Discursive Power in Contemporary Media Systems

Contemporary media systems are shaped by diverse constellation of organizations, groups, and individuals contributing information to national and international news flows. In our project, we analyze interdependencies and power relationships among these new constellations. We do so through the concept of discursive power: the ability of contributors to communication spaces to introduce, amplify, and maintain topics, frames, and speakers in interconnected communication spaces.

Dynamic creation of nationwide virtual panels for collective behavior prediction

The objective of this research is to develop a predictive system that enables stakeholders (e.g. policymakers, politicians, celebrities, and business organizations) to know how people will behave in the future and that provides a solid understanding of these behaviors to help stakeholders' strategic planning. In particular, we will exploit past behaviors to predict future behaviors.
