The Arab Spring| Digital Media in the Egyptian Revolution: Descriptive Analysis from the Tahrir Data Set

Abstract: The Tahrir Data Project gathers empirical data on media use during the Egyptian revolution of January and February 2011. The Project consists of three data sets documenting media use by protesters, by coordinators, and by transnational audiences. Preliminary descriptive analysis of the data suggests that social media use was not dominant in demonstrations, but may have played an important role in connecting and motivating protesters. Metrics for media use by protesters indicate a strong presence of activities and characteristics commonly associated with communication in protests to social media and social media users. These metrics, along with preliminary data on coordinator strategies and preliminary analysis of the #jan25 tweet set, suggest an important but complex role played by social media in the Egyptian revolution of 2011. The data and preliminary analysis are presented here, together with a number of research questions for further study.

Polymedia: Towards a new theory of digital media in interpersonal communication / transl. from Eng. A. Paukova, V. Chumakova

Abstract: This article develops a new theory of polymedia in order to understand the consequences of digital media in the context of interpersonal communication. Drawing on illustrative examples from a comparative ethnography of Filipino and Caribbean transnational families, the article develops the contours of a theory of polymedia. We demonstrate how users avail themselves of new media as a communicative environment of affordances rather than as a catalogue of ever proliferating but discrete technologies. As a consequence, with polymedia the primary concern shifts from the constraints imposed by each individual medium to an emphasis upon the social, emotional and moral consequences of choosing between those different media. As the choice of medium acquires communicative intent, navigating the environment of polymedia becomes inextricably linked to the ways in which interpersonal relationships are experienced and managed. Polymedia is ultimately about a new relationship between the social and the technological, rather than merely a shift in the technology itself.
