We report a large-scale coronal wave (so-called “EIT wave”) observed with high cadence by EUVI onboard STEREO in association with the GOES B9.5 flare and double CME event on 19 May 2007. The EUVI instruments provide us with the unprecedented opportunity to study the dynamics of flare/CME associated coronal waves. The coronal wave under study reveals deceleration, indicative of a freely propagat...

Public and private organizations in various areas are setting up digital Information Infrastructures (IIs) for interconnecting government, businesses and citizens. IIs can create value by sharing and integrating data of multiple actors. This can be the basis for value added services and especially collaborations of public and private partners can make IIs thrive. Easier access to integrated ser...

We review the current status of the ’Parker hypothesis’ which suggests that the solar corona is heated by a multitude of small flare-like events called nanoflares. Space-born coronal imagers such as SXT, EIT or TRACE have allowed to test Parker’s hypothesis observationally. Combining the results from different authors it seems that we are close to falsifying the hypothesis, i.e. there are not e...

This article reports a pioneering case study of a crowdsourced law-reform process in Finland. In the crowdsourcing experiment, the public was invited to contribute to the law-reform process by sharing their knowledge and ideas for a better policy. This article introduces a normative design framework of five principles for crowdsourced policymaking: inclusiveness, accountability, transparency, m...
