Public engagement with science-Origins, motives and impact in academic literature and science policy.

'Public engagement with science' has become a 'buzzword' reflecting a concern about the widening gap between science and society and efforts to bridge this gap. This study is a comprehensive analysis of the development of the 'engagement' rhetoric in the pertinent academic literature on science communication and in science policy documents. By way of a content analysis of articles published in three leading science communication journals and a selection of science policy documents from the United Kingdom (UK), the United States of America (USA), the European Union (EU), and South Africa (SA), the variety of motives underlying this rhetoric, as well as the impact it has on science policies, are analyzed. The analysis of the science communication journals reveals an increasingly vague and inclusive definition of 'engagement' as well as of the 'public' being addressed, and a diverse range of motives driving the rhetoric. Similar observations can be made about the science policy documents. This study corroborates an earlier diagnosis that rhetoric is running ahead of practice and suggests that communication and engagement with clearly defined stakeholder groups about specific problems and the pertinent scientific knowledge will be a more successful manner of 'engagement'.

Novel interfaces in science communication: Comparing journalistic and social media uptake of articles published by The Conversation Africa.

Science amplifier platforms such as The Conversation have gained popularity in a changing media ecosystem in which the traditional roles of journalists are eroded, and scientists are urged to engage with society. The Conversation constitutes a blend of scientific communication, public science communication and science journalism, and a convergence of the professional worlds of science and journalism. In this study, we investigated the nature and impact of the Africa-focussed edition of this platform, The Conversation Africa. We analysed articles published over a 5-year period since its launch in 2015 (N = 5392). Contents from South Africa dominate the platform, but contributions from other African countries are increasing. Regarding the role of The Conversation Africa as an inter-media agenda setter, mainstream media more often republished stories related to politics or economics, while stories about social issues such as education, conservation and art were more often shared on social media.
