Nahon, Karine, Hemsley, Jeff, Walker, Shawn and Hussain, Muzammil (2011): Blogs: spinning a web of virality. In: Proceedings of the 2011 iConference 2011. pp. 348-355. http://dx.doi.org/10.1145/1940761.1940809

The aim of this study is to understand the role of bloggers in driving viral information. More specifically, we develop a new methodology that creates a map of the 'life cycle' of blogs posting links to viral information. Our dataset focuses blogs linking to the most significant viral videos of the 2008 US presidential election. To do so, we gathered data on all blogs (n=9,765) and their posts (n=13,173) linking to 65 of the top US presidential election videos that went viral on the Internet during the period between March 2007 and June 2009. Among other things, our findings illuminate the importance of different types of blogs: elite, top-political, top-general and tail blogs. We also found that while elite and top-general blogs create political information, they drive and sustain the viral process, whereas top-political and tail blogs act as followers in the process.

Ostergren, Marilyn, Hemsley, Jeff, Belarde-Lewis, Miranda and Walker, Shawn (2011): A vision for information visualization in information science. In: Proceedings of the 2011 iConference 2011. pp. 531-537. http://dx.doi.org/10.1145/1940761.1940834

This paper presents the case for Information Visualization (IV) to be a central, integrated component of study in Information Science. We summarize the current state of IV within iSchools, the market demand for IV skills, the intellectual contributions of IV to the field of Information Science and the potential intellectual contributions of Information Science to the field of IV. We conclude with three, non-exclusive scenarios for the inclusion of IV into the iSchool curriculum as first steps toward realizing this: integration throughout the curriculum, a core course, and a specialization tract.
