The research field of science communication is fairly neglected in South Africa. The university system in South Africa, with a few exceptions, pays scant attention to the teaching of science communication, leading to limited academic knowledge of this research field with its rich history and philosophical relations. This paper explores some of the reasons behind this neglect of science communication in South Africa and will argue and demonstrate that, primarily, two political systems can be identified as having had a profound impact on the lesser attention given to this research field; the ‘divide and rule’ system of British colonialism and the Afrikaner National Party ‘apartheid’ system of racial segregation.

In this paper, we identify some milestones in the construction process for mobile science museums and centres in Brazil. As background for presenting the Brazilian context, we initially address the records found on the earliest travelling museum exhibitions and mobile museums in Europe and North America. We then introduce the role of UNESCO in the promotion and implementation of travelling science exhibitions and museums in several countries. Finally, we document important events in the history of mobile science museum and centres in Brazil and outline three general and inter-related challenges currently faced by them.

The history of public communication of science in Spain is yet to be written. Few academic studies exist that have tackled this subject. The political and economic history of the country have marked out the evolution of this discipline, which burst into the country at the end of the 20th century with the proliferation of initiatives such as the creation of science museums, the building of the Spanish Science Foundation and the development of a public Scientific Information service. Despite these efforts, the level of scientific culture for Spanish people is one of the lowest in Europe [OECD, 2016].

During the course of several decades, several scientists and groups of scientists lobbied the British Broadcasting Corporation (BBC) about science broadcasting. A consistent theme of the interventions was that science broadcasting should be given exceptional treatment both in its content, which was to have a strongly didactic element, and in its managerial arrangements within the BBC. This privileging of science would have amounted to ‘scientific exceptionalism’. The article looks at the nature of this exceptionalism and broadcasters' responses to it.

Science communication is today a well-established ―although young― area of research. However, there are only a few books and papers analyzing how science communication has developed historically. Aiming to, in some way, contribute to filling this gap, JCOM organized this special issue on the History of Public Communication of Science and Technology (PCST), joining 15 contributions, from different parts of the globe. The papers published in this issue are organized in three groups, though with diffuse boundaries: geography, media, and discipline. The first group contains works that deal descriptively and critically with the development of PCST actions and either general or specific public policies for this area in specific countries. A second set of papers examines aspects of building science communication on TV or in print media. The third group of papers presents and discusses important PCST cases in specific areas of science or technology at various historical moments.

Japan's policy of “public understanding of science” (PUS) has shifted to “science communication” since 2003. That year, there were a number of simultaneous developments with regard to science communication. The key report that advocated for the promotion of science communication and a textbook on science communication were published then. The most important consequence was that the report triggered a policy change at the Ministry of Education, Culture, Sports, Science and Technology (MEXT). The following year, MEXT published the White Paper on Science and Technology 2004, the main theme of which was concerned with science communication. Although the shift may have begun as a somewhat top-down contrivance, it has subsequently sunk down firm roots throughout Japan. In 2011 the Japanese Association for Science Communication was founded. People's awareness of science communication was significantly changed by the Great East Japan Earthquake that occurred on March 11, 2011. Why was such a policy shift possible? How did such a cascade effect occur? This paper will discuss the reasons behind these phenomena.

In the last decades of the 19th century education played a major role in Mexican society, when efforts were being made to restructure it based on the objective teaching of sciences, which was regarded as the driving force behind the change needed in various sectors such as industry and public health. In this context, the so-called science disseminators aimed to communicate their knowledge to the general public, mainly to the working classes and the children. Journalism grew and reached a wide range of themes and audiences. They believed in the idea of a science for all and that sciences were an instrument to know the new nations and educate the population. It is worth mentioning La ciencia recreativa, a publication dedicated to children and working classes. Between 1871 and 1879 it was edited by the topographical engineer and surveyor José Joaquín Arriaga (1831–1896), who aimed to generalise the scientific knowledge of cosmography, mineralogy, meteorology, physics, botany, zoology, descriptive geography and industrial agriculture.

This article examines certain guiding tenets of science journalism in the era of big data by focusing on its engagement with citizen science. Having placed citizen science in historical context, it highlights early interventions intended to help establish the basis for an alternative epistemological ethos recognising the scientist as citizen and the citizen as scientist. Next, the article assesses further implications for science journalism by examining the challenges posed by big data in the realm of citizen science. Pertinent issues include potential risks associated with data quality, access dynamics, the difficulty investigating algorithms, and concerns about certain constraints impacting on transparency and accountability.

Social media is restructuring the dynamics of science communication processes inside and outside the scientific world. As concerns science communication addressed to the general public, we are witnessing the advent of communication practices that are more similar to public relations than to the traditional processes of the Public Understanding of Science. By analysing the digital communication strategies implemented for the anti-vaccination documentary Vaxxed, the paper illustrates these new communication dynamics, that are both social and computational.

Thanks, on the one hand, to the extraordinary availability of colossal textual archives and, on the other hand, to advances in computational possibilities, today the social scientist has at their disposal an extraordinary laboratory, made of millions of interacting subjects and billions of texts. An unprecedented, yet challenging, opportunity for science. How to test, corroborate models? How to control, interpret and validate Big Data? What is the role of theory in the universe of patterns and statistical correlations? In this article, we will show some general characteristics of the use of computational tools for the analysis of texts, and some applications in the areas of public communication of S&T and Science and Technology Studies (STS), also showing some of their limitations and pitfalls.
