Up next at AoIR 2012 is Zizi Papacharissi, whose focus is on structures of affect and their connection to political engagement. What is the texture of feeling here – for example in the expression of sentiment on Twitter? In her talk here, Zizi will focus on the #egypt hashtag.

The next plenary session at AoIR 2012 starts with Daniel Miller, who describes enthnography as often grand in its ambitions, but sometimes a little parochial in its work – how do you go about developing some of the wider theory about technology and what it means to be human, for example? What needs to happen here is a move between the broad and the specific.

The post-lunch keynote at AoIR 2012 is by Liesbet van Zoonen, who begins with a recap of cultural theories of identity. These assume both individual and collective identities to be multiple rather than single, dynamic rather than static. Identity is something we do, not something we are. Research has been informed by these ideas, and we have a good understanding of how different groups use media to perform their identities. This has also been reflected in an understanding of diversity as a desirable goal for social policy.

Well, as Tuesday's blogburst already indicated, I'm slowly progressing on my current travels. The event at the Copenhagen Centre for Communication and Computing was something of a preview for a panel on "Digital Data – Lost, Found, and Made" which is on the programme for the 2012 conference of the Association of Internet Researchers here in Salford; expect plenty of liveblogging from that conference to start tomorrow.

Before this conference and the Copenhagen event, though, I spent a few days in Helsinki, where I gave two guest lectures in the international Masters course – and I've neglected to post those lectures here so far. So, here they are. Unfortunately, my audio recorder ran out of batteries during the first lecture, so there are only slides for it - however, that lecture was a repeat of my SBPJor keynote in Brazil last October, so you can go to those slides for the audio.

Below are the two lectures:

My own paper started the post-lunch session at the CCC Symposium, discussing our Mapping Online Publics work in the field of Twitter research. I'll post up the slides and audio properly as soon as I can!

Slides and audio are below:

The next speaker at the CCC symposium is the fabulous Nancy Baym, who begins by noting how overwhelming the buzz about 'big data' has become. There's a great deal of fascination just with the things we can do with big data sources - tracing interesting patterns, attempting to predict future processes, making sense of data by using algorithmic tools.
