Research in the field of science communication started emerging about 50 years ago and has since then matured as a field of academic enquiry. Early findings about research-active authors and countries reveal that scholarly activity in the field has traditionally been dominated by male authors from English-speaking countries in the West. The current study is a systematic, bibliographic analysis of a full sample of research papers that were published in the three most prominent journals in the field from 1979 to 2016. The findings reveal that early inequities remain prevalent, but also that there are indications that recent increases in research outputs and trends in authorship patterns ― for example the growth in female authorship ― are beginning to correct some of these imbalances. Furthermore, the current study verifies earlier indications that science communication research is becoming increasingly institutionalised and internationalised, as demonstrated by an upward trend in papers reflecting cross-institutional collaboration and the diversity of countries where authors are based.

There is a gap between the discipline of economics and the public it is supposedly about and for. This gap is reminiscent of the divide that led to movements for the public understanding of and public engagement with the natural sciences. It is a gap in knowledge, trust, and opinions, but most of all it is a gap in engagement. In this paper we ask: What do we need to think about ― and what do we need to do ― in order to bring economics and its public into closer dialogue? At stake is engaged, critical democracy. We turn to the fields of public understanding of science and science studies for our approach, finding three themes of particular relevance: understanding, expertise, and audience. We then discuss participatory budgeting (PB) as an example of fertile ground for engagement. We argue that with an economic-engagement focus, activities such as PB could be extended into the public-economics gap and provide avenues for an economic equivalent of participatory science: a form of participatory economics.

This article provides a starting position and scene-setter for an invited commentary series on science communication and public intellectualism. It begins by briefly considering what intellectualism and public intellectualism are, before discussing their relationship with science communication, especially in academia. It ends with a call to science communication academics and practitioners to either become more active in challenging the status quo, or to help support those who wish to by engendering a professional environment that encourages risk-taking and speaking-out in public about critical social issues.

Arthur Dent's reluctant hitchhike through the Milky Way would not have been possible without the babelfish, which was nourished by his brain waves and in return decoded foreign languages for him. In much the same way, public intellectuals serve as science and technology academia's babelfish for the non-STEM savvy. While STEM academics continue to push back the frontiers of knowledge, public intellectuals equip the community with the knowledge we need to make big decisions, both for our own individual lives and for our society.

This commentary is both a case study of the evolution of one public intellectual, and an analysis of how he has broadened his voice beyond the standard academic bubble. His story gives a perspective on the question of, “How do public intellectuals get their start?” They almost certainly begin as “mere” intellectuals — the public part comes later. But how? How does a studious academic go from following the media to being part of the media?

While science communication has become increasingly professionalised, philosophers have been far less active in, and reflective about, how we talk to the public. In thinking about the relationship between the ‘public intellectual’ and science communication, however,  philosophy has some important contributions to make, despite the differences of content and disciplinary approach. What, then, can both these professions learn from each other about how to engage with the public - and the risks that this might involve?

In an information free-for-all why should scientists bother to add their voice? In this commentary piece I argue there is an increasingly important role for scientists amongst the growing ranks of public intellectuals and the many who style themselves as such. First, we must become the sifters and sorters. We need to be willing to use our research and analytical skills to identify what is valuable amongst all the noise, and, if necessary, to volubly reject what is not. And, second, we need to create and defend the space everyone needs for deep thought and consideration. We need to influence ongoing debates by seeking to push them towards evidence-based arguments and areas of scientific consensus. To sift out the deliberately distracting stories and to counter fake news.

Reflecting on the public role of academics, this issue of JCOM includes a set of commentaries exploring public intellectuals and intellectualism. The commentaries explore the role of academics in public debates, both as bringers of facts and passion. These pieces, together with past commentaries and letters to JCOM raise interesting questions about the role of academics in public debates that are, perhaps not those usually trodden in the academic literature.

This article proposes a classification of the current differences between online videos produced specifically for television and online videos produced for the Internet, based on online audiovisual production on climate change. The classification, which consists of 18 formats divided into two groups that allow comparisons to be made between television and web formats, was created through the quantitative and qualitative content analysis of a sample of 300 videos. The findings show that online video's capacity to generate visits is greater when it has been designed to be broadcast on the Internet than when produced for television.

van den Sanden and Vries curate reflections and insights about the shared goals, practices and processes which bring together academics and practitioners in science education and communication. The book spotlights areas of productive overlap but is just the beginning for meaningful collaboration.
