The next AoIR 2015 speaker is Anna Sophia Kümpel, whose interest is in news usage patterns and their effects on political participatory behaviours. Mass media remain identified as a crucial determinant of political participatory behaviour, though their exact effects on participation remain disputed. One new factor which emerges in addition to this in more recent times is the question of which devices are being used.

Anna's project used a representative sample of German media users, and asked participants about how they learnt about news events, how they obtained further information, and what devices they used as they did so, as …

I arrived a little late to Tanja Aitamurto's AoIR 2015 paper about crowdsourced journalism in northern Europe, where news sites used their readers to gather data on homeloan terms, for instance – crowdsourcing is thus defined as a mechanism for collaborative problem-solving that is driven by the initiator of the project; the locus of power therefore remains with the media organisation.

Another crowdsourced journalistic project examined the trading documents of a large number of stock market brokers to identify cases of short-stock selling; here, the project revealed serious misconduct an a Finnish bank executive was fired.

Up next at AoIR 2015 is the fabulous Luca Rossi, whose interest is in how scientific media events are now mediated via Twitter. His focus here is on the Rosetta mission and the Philae probe's landing on comet Churyumov-Gerasimenko. The mission was launched before Twitter was, but the approach and landing of the probe was covered closely by dedicated Twitter accounts and in widely promoted hashtags like #WakeUpRosetta.

This created a great deal of awareness and anticipation, and Luca's project gathered some 400,000 tweets related to the relevant hashtags. Using the approach for classifying hashtags that Stefan Stieglitz and …

The final speaker at ECREA 2014 is Veera Kangaspunta, who notes the importance of studying the audience behind online news comments. Traditionally, journalists have seen online news as a sideshow to the real news business, and online comments are thus a sideshow to the sideshow – but this is changing. While the quality of online commentary is often limited, and discussions may drift, they may be studied to reveal a great deal more about audience attitudes.

Veera's case study is focussing on an environmental accident in Finland and its coverage across local and national newspapers. The accident has a very …

The next presenters in this ECREA 2014 session are Susanne Almgren and Tobias Olsson, who continue the theme of user comments on online news. Digital media offer new forms of co-existence between producers and users; indeed, there is a new media ecology of participation emerging.

User-generated content has always played a part even in traditional media, of course, in the form of letters to the editor or telephone call-ins. The current environment simply makes such harnessing of user-generated content a great deal easier. Online newspapers are a particularly interesting case for this, given their long institutional history.
