Just out in the new issue of Communication Research – an article combining social psychology and social network theory to explore transactive  memory processes.

Communication Research

Article abstract:
“Building on Kozlwoski and Klein’s emergence framework, this research developed and tested a set of multilevel hypotheses regarding individual and team transactive memory processes in work teams. Literature from social psychology suggested hypotheses on how shared task interdependence influences individual expertise exchange. Social network theory suggested hypotheses that individual expertise exchange is channeled according to communication tie strength. Using data collected from 218 individuals from 18 organizational teams, the proposed hypotheses were tested using hierarchical linear modeling techniques. The results showed that at the individual level the relationship between directory development and expertise exchange was mediated by communication tie strength and moderated by shared task interdependence.Team-level variables also were significantly related to individual-level outcomes such that individual expertise exchange happened more frequently in teams with well-developed team-level expertise directories, as well as with higher team communication tie strength and shared task interdependence.”

“Communication Power“, the latest book of USC Annenberg professor Manuel Castells has been published this month by the Oxford University Press.

From the publisher’s  description:

Manuel Castells

We live in the midst of a revolution in communication technologies that affects the way in which people feel, think, and behave. The mass media (including web-based media), Manuel Castells argues, has become the space where political and business power strategies are played out; power now lies in the hands of those who understand or control communication.

Over the last thirty years, Castells has emerged as one of the world’s leading communications theorists. In this, his most far-reaching book for a decade, he explores the nature of power itself, in the new communications environment.

His vision encompasses business, media, neuroscience, technology, and, above all, politics. His case histories include global media deregulation, the misinformation that surrounded the invasion of Iraq, environmental movements, the role of the internet in the Obama presidential campaign, and media control in Russia and China.

In the new network society of instant messaging, social networking, and blogging – “mass self-communication” – politics is fundamentally media politics. This fact is behind a worldwide crisis of political legitimacy that challenges the meaning of democracy in much of the world. Deeply researched, far-reaching in scope, and incisively argued, this is a book for anyone who wants to understand the dynamics and character of the modern world. Read the rest of this entry »
