The final speaker in this AoIR 2013 panel is Tim Highfield, whose focus is on the doping scandal surrounding Lance Armstrong between August 2013 and January 2013, from USADA stripping Armstrong of his titles to his confession interview with Oprah. This draws on a number of different datasets, including tweets mentioning @lancearmstrong during the 2012 Tour de France as well as tweets mentioning 'Armstrong' in subsequent months.

During the 2012 Tour, reports emerged that several riders had testified against Armstrong, generating substantial discussion with the Tour de France Twitter community as an extension of the fan/athlete para social interaction - with fans making both critical and supportive statements towards Armstrong. Subsequent spikes in activity surround Armstrong's stepping down from the Livestrong foundation and the Oprah interviews.

The second presenter in our AoIR 2013 celebrity crisis panel is Ana Vimieiro, whose focus is on the crisis around Oscar Pistorius following the death of his girlfriend Reeva Steenkamp. Ana's approach in this is to use frame analysis to explore how the crisis is being conceptualised by the users discussing it on Twitter.

There are various approaches to frame analysis: holistic variable coding, a textual focus on terms and expressions (which ultimately focusses on topics more than frames), and data reduction techniques which draw on clustering approaches. Ana is employing the latter model, coding the text for less subjective categories including sources, causes, solutions, consequences, metaphors, slogans, examples, and moral judgments.

The post-lunch session at AoIR 2013 starts with a panel on celebrity crises, which has now become a QUT-only affair. We're starting with a paper by Theresa Sauter and me, on the Pope's @pontifex account. (Slides and audio are below.) Celebrity accounts in general are one of the big drivers of Twitter activity, as Twitter itself positions them. The @pontifex account was set up in December 2012 by Benedict XVI, with nine different language accounts set up, including one in Latin.

We tracked the English-language account, which had gathered 1.6 million followers by the time Benedict XVI resigned. He'd mainly posted brief prayer-style messages, coordinated across all languages, and the new pope Francis has done much the same since then. This is perhaps unsurprising given the status of the Pope.

The final speaker in our AoIR 2013 panel is Fabio Giglietto, who presents a season-long study of Twitter use alongside 11 Italian TV talkshows. Twitter use alongside such shows can reveal the power struggles between political and media actors and everyday citizens.

Fabio's team bought Gnip data for the relevant hashtags related to these 11 talkshows, adding up to some 2.5 million shows. 76% of these were made while the shows were on air, with some 187,000 unique on-air contributors. The team also identified the key peaks in engagement, and associated them with specific time windows within the broadcasts; they then conducted a content analysis of the tweets posted and the content broadcast during these windows.

The next presentation in this AoIR 2013 panel is by Pieter Verdegem and Evelin D'Heer, whose interest is in the role of Twitter in second-screen viewing. Twitter has been pushing this very strongly, but is social TV actually something new? We've seen attention to the social uses of television at least since the 1990s, through ethnographic research, but the use of social media has spread these practices further and connected users more widely.

Twitter can be a useful tool for measuring audience participation, but we also need to take into account the Twitter userbase in each country - in Belgium, some 20% of the population are said to be on Twitter, for example, but that group is neither demographically representative nor are they necessarily all active participants.

This morning at AoIR 2013 starts for me with one of my own presentations - a paper on the use of Twitter by German football clubs that Katrin Weller and I have co-authored. I'll add in the slides and audio as soon as I can - consider this post a placeholder for later...

The final paper in our panel at AoIR 2013 is by Anders Larsson and Bente Kalsnes, looking at the Norwegian election on 9 Sep. Their work examines the use of Twitter by citizens, politicians, and journalists. One starting point for this were the #valg2013 and #valg13 hashtags, to identify what users are being mentioned in these hashtags - which showed that then-PM Jens Stoltenberg was @mentioned frequently but did not often reply, while the Greens party both sent and received many hashtagged tweets. Amongst the retweeters, one-off messages which receive substantial retweets can become prominent, but more frequently retweeted users tend to be celebrities (comedians, journalists, etc.)

A second approach was to examine the Twitter uses by some of the key party leaders. As it turns out, during the month before the election there was a strong focus on @replying, especially from the leaders of the smaller parties. Their communication is mainly with their own supporters - there are very few users who received @replies from two or more leading politicians (and these are largely journalists and other media figures, not everyday citizens).

The next paper in our AoIR 2013 panel is by Julia Neubarth and Christian Nuernbergk, covering the German federal election two days after the Australian one. The Net is playing an increasingly important role in political communication in Germany, but there is still very little active participation by citizens, and active participants are mainly male, younger, and left-wing. Politicians are getting more active - some 60% of federal parliamentarians are on Twitter, although Chancellor Merkel still isn't.

German politicians on Twitter will find a mixed audience - use in the country is growing, but still limited; however, active participants are especially interesting as they represent journalists and other media personnel as well as especially politically interested users.

The next paper in our AoIR 2013 panel is by Theresa Sauter, Tim Highfield and me. Here are the slides - audio to come later now with audio...
