Up next in our ECREA 2018 panel is Christian Nuernbergk, who presents our work on the social media activities of journalists; the slides are embedded below. We are interested here in how journalists have incorporated social media like Twitter into their professional toolkits, but also in how audiences engage with them and how journalists respond in turn (if indeed they do). Studies of how ordinary Twitter users engage with journalists on an everyday basis are especially rare still.

The next speaker in this ECREA 2018 session is Javier Ruiz Soler, whose interest is in locating a transnational public sphere on Twitter, in the context of the EU. Many scholars are sceptical of the idea of a European public sphere, due to language and national differences, while others point to the emergence of a growing overlap between national communities and discussions.

The first panel on this final day of ECREA 2018 starts early (!), and begins with Frederic Guerrero-Solé. His work examines the overlaps of retweet networks for the posts of Spanish politicians and media. Frederic considers such retweeters to be active audiences for politicians; more passive audiences would be able to be studied by examining the followers of these accounts, but this is considerably more difficult.

The next speaker at AoIR 2018 is Gabriela Zago, who shifts our focus to the prevalence of ‘fake news’ in Brazilian politics; she is looking especially at the use of Twitter in the impeachment of President Dilma Rousseff. Twitter is an important social medium in Brazil, and especially features many social influencers including politicians, journalists, and celebrities.

The last paper in this AoIR 2018 session was mine, presenting on our TrISMA project to gather social media data in Australia at scale. Here are the slides:

Impressively, the Monday keynote at ICA 2018 is by Elihu Katz, whose considerable impact on communication research does of course reach back to the 1950s. He begins by noting the important role that Paul Lazarsfeld played in restoring interpersonal communication to the study of communication, a development which is crucial to the study of social networks today.

Lazarsfeld became interested in radio in the 1930s, and was also intrigued by the psychology of decision-making; he combined this in his studies of voters in Ohio over an extended period of time. This enabled him to identify voters who changed their minds during the course of an election campaign – a change which was attributed not mainly to media coverage, but to the role of better-informed opinion leaders. This was the basis for the theory of the two-step flow, which was be proven in subsequent studies that examined the roles of both influencers and influencees and identified different spheres of influence.

Together with some of my colleagues from the QUT Digital Media Research Centre, I’ve just released a new, detailed analysis of the structure of the Australian Twittersphere. Covering some 3.72 million Australian Twitter accounts, the 167 million follower/followee connections between them, and the 118 million tweets posted by these accounts during the first quarter of 2017, the new article with Brenda Moon, Felix Münch, and Troy Sadkowsky, published in December 2017 in the open-access journal Social Media + Society, maps the structure of the best-connected core of the Australian Twittersphere network:

The Australian Twittersphere in 2016: Mapping the Follower/Followee Network

Twitter is now a key platform for public communication between a diverse range of participants, but the overall shape of the communication network it provides remains largely unknown. This article provides a detailed overview of the network structure of the Australian Twittersphere and identifies the thematic drivers of the key clusters within the network. We identify some 3.72 million Australian Twitter accounts and map the follower/followee connections between the 255,000 most connected accounts; we utilize community detection algorithms to identify the major clusters within this network and examine their account populations to identify their constitutive themes; we examine account creation dates and reconstruct a timeline for the Twitter adoption process among different communities; and we examine lifetime and recent tweeting patterns to determine the historically and currently most active clusters in the network. In combination, this offers the first rigorous and comprehensive study of the network structure of an entire national Twittersphere.

I published a preview of some of the study’s key findings in The Conversation in May 2017. Meanwhile, my paper at the Future of Journalism conference in Cardiff in September 2017 built on this new Twittersphere map to test for the existence of echo chambers and filter bubbles in Australian Twitter – and found little evidence to support the thesis:

The next speaker in this AoIR 2017 session is Marco Bastos, whose focus is on the Brexit referendum. He notes that a substantial number of bots were active in the Brexit debate on Twitter, yet many of these accounts disappeared immediately after the referendum. But it is also important to distinguish between different bots: there are legitimate bot developers that offer such accounts, while genuine, highly active users are sometimes also misidentified as bots.
