Catechism, a literary genre of a religious origin, was once employed in the teaching of ‘lay’ subjects, especially of a technical nature. This is a review of this past editorial tradition which illustrates the potentialities and the limitations of agrarian catechisms, with a special focus on their spreading across Southern Italy in the late Enlightenment. This paper reflects on whether a book was the best instrument to hand down procedures and notions to people who supposedly were illiterate or unschooled.

The Internet and digital media are changing science books. They change the way readers approach books and change the way books present their contents. Probably, the Internet and digital media are also changing the contents themselves.

This article examines the public at a science exhibition or festival and tries to determine whether casual visitors are a means of expanding the audience. According to a Swiss survey of public attitudes towards science (2005), the non-public of a science exhibition or festival is distinguished by demographics such as gender and education (more female and less educated), cultural practices (less frequent) and attitudes towards science (less positive). Considering the Swiss science festival of 2009, casual visitors differ from intentional ones in terms of sociodemographic aspects and scientific cultural practices; on the other hand, casual visitors are close to intentional ones in terms of non-scientific cultural practices and attitudes towards science. Consequently, casual visitors are one way of increasing audiences.

A survey we carried out in upper secondary schools showed that the majority of the students consider physics as an important resource, yet as essentially connected to technology in strict terms, and not contributing “culture”, being too difficult a subject. Its appreciation tends to fade as their education progresses through the grades. The search for physics communication methods to increase interest and motivation among students prompted the Department of Physics at the University of Milan to establish the Laboratory of ScienzATeatro (SAT) in 2004. Up to May 2010, SAT staged three shows and one lesson-show having physics as a main theme, for students attending any grades at school. Good indicators of the efficacy of those shows are: the number of repeats (256 of them up to May 2010), the reputation of the theatres in which they were performed, and the results of two surveys on the achievement of the goals, which saw the participation of over 50 classes each.

A workshop on science journalism organised at SISSA of Trieste, Italy a few weeks ago outlined scenarios that should serve as a source for debate among professionals and scholars to grasp how information activities regarding science, medicine and technology will evolve in the next few years. It is a time of great uncertainty, yet a common path to venture through can be made out: the new science journalism should meditate on a different concept of science, an in-depth conceptualisation of different audiences, alternative narrations and its role in the democratisation of knowledge within a knowledge-based society.

Media and communications technologies play a significant role in disaster management procedures in regards to the mobilization of resources in emergency situations. While the dissemination of warning messages relayed via broadcast technologies have had some positive outcomes in terms of reducing casualties in emergency situations in Bangladesh, there remain some specific problems in regards to the manner in which these messages are distributed within this developing nation. These problems are addressed within this paper. Examining the existing cyclonic warning dissemination system and the manner in which warning information is distributed and received, this study addresses citizen responses to mediated warning messages in the vulnerable coastal regions of Bangladesh. The results indicate that attitudes towards mediated warnings held by Bangladeshi citizens in these environs differ depending upon their access to media, type of dwelling and differing levels of literacy. This study also provides recommendations for media professionals and policymakers in regards to disseminating more effective warnings to the inhabitants of Bangladesh's cyclone-prone coastal belt.

The purpose of this commentary is extending and enriching the discussion raised in the “Science Journalism and Power in the 21st Century” workshop, held last month in the context of MAPPE project at SISSA, Trieste. We collected three interviews of authors expert in communication and media on different fields strongly influenced by participatory communication practices: Anabela Carvalho (global warming and climate change), Pieter Maeseele (technological risks) and Denise Silber (‘eHealth’ and ‘Health 2.0’). The interviews therefore analyze three different perspectives of a more general issue: How is the ecosystem of scientific information changing by means of a new concept of ‘public’? Which are the new ways in which citizens produce and manage scientific information? What could be a new role for science journalism? These three interviews aim to delve, from a theoretical point of view, into the sociological framework of an ecosystem of information driven by active public participation in the communicative practices. Emphasis will be put on the way in which scientific knowledge is reconstructed and negotiated in the Web 2.0 arena: democracy in the knowledge society intrinsically depends on a fair outcome of this process. Nevertheless, the crisis of traditional media and journalist’s figure is threatening the democratization of science. In this sense, the social function of journalism is still – and will be – unescapable. The re-distribution of social power by means of Web 2.0 is a key issue, and new sensible communication practices and professionals are needed.

Technoscientific risks have been creating a growing social demand for participation in the scientific citizenship. This interview will emphasize that decision making (and so, in a more general sense, democracy) in the knowledge society requires new mediatic forums and new communication processes suitable to the highly multi- and inter-disciplinary nature of modern social debates. It argues that a new research agenda for risk conflicts, and a more neutral role for science journalism, are needed.

Climate change is a multi-faceted issue. It relies on deep scientific bases, but merges with politics, economics, ethics and culture in a complex and strongly nonlinear social debate. This interview focuses on the relationships between public communication on climate change (with emphasis on the so-called ‘new media’) and the decision making processes. It argues that more productive and sustainable forms of communication on climate change are needed due to problems related with validation of information in the Web.

Public communication on health issues on the Internet is not only a matter of popularization of medical information. It deeply deals with narration, conversation and dialogue, which are typical values in the Web 2.0. This interview will emphasize that blogs, forums, wiki are new ways in which population has been reconstructing and integrating medical knowledge. These ways are re-defining medical knowledge by means of unhinging the standard medical communication practices, based on a linear diffusion of knowledge form experts to laypeople.
