Science, politics, industry, media, state-run and private organisations, private citizens: everyone has their own demands, their own heritage of knowledge, thoughts, opinions, aspirations, needs. Different worlds that interact, question one another, discuss; in one word: they communicate. It is a complicated process that requires professionals «who clearly understand the key aspects of the transmission of scientific knowledge to society through the different essential communication channels for multiple organizations». The purpose of this commentary is to cast some light upon the goals, the philosophy and the organisation behind some European and extra-European Master’s degrees in science communication. We have asked the directors of each of them to describe their founding elements, their origins, their specific features, their structure, their goals, the reasons why they were established and the evolution they have seen over their history.

In his latest book “The scientific life. A moral history of a late modern vocation”, the social historian of science Steven Shapin addresses the public image of contemporary scientists, their virtues and vocations. Who are, and how they represent themselves, those scientists who work on the edge between industry and academy, and who are responsible for the radical uncertainty embedded in the contemporary production of scientific knowledge? If “people matter”, as Shapin states, the genealogy he provides should encourage us to dig more deeply in the main stage of the virtues and ethos of scientists: the mass media.

One of the main purposes of weather forecasting is that of protecting weather-sensitive human activities. Forecasts issued in the probabilistic form have a higher informative content, as opposed to deterministic one, since they bear information that give also a measure of their own uncertainty. However, in order to make an appropriate and effective use of this kind of forecasts in an operational setting, communication becomes significatively relevant.The present paper, after having briefly examined the weather forecasts concerning Hurricane Charley (August 2004), tackles the issue of the communicative process in detail.The bottom line of this study is that for the weather forecast to achieve its best predictive potential, an in-depth analysis of communication issues is necessary.

There is a compelling need to ensure that the points of view and preferences of stakeholders are fully considered and incorporated into natural resources management strategies. Stakeholders include a diverse group of individuals in several sectors that have an interest in how natural resources are managed. Typically, stakeholders with an interest in groundwater resources include groups who could be affected by the manner in which the resource is managed (e.g., farmers who need water for irrigation; municipalities and individuals who need drinking water, agencies and organizations that want to maintain in-stream flows to support ecosystems, etc.) Refugio County in South Texas provides an interesting case study since several groups of water users in the region are working with researchers at Texas A&M University-Kingsville (TAMUK) to develop decision-support models that incorporate stakeholder concerns. The focus of this paper is to provide a series of arguments and approaches about the ways in which stakeholder issues have recently been incorporated into environmental models, to briefly describe some of the TAMUK efforts to develop groundwater models that incorporate stakeholder inputs, and to present and discuss a method in which communication research can be used to obtain stakeholder preferences input into modeling efforts.

Mouse-related research in the life sciences has expanded remarkably over the last two decades, resulting in growing use of the term “mouse model”. Our interviews with 64 leading Japanese life sciences researchers showed heterogeneities in the definition of “mouse model” in the Japanese life sciences community. Here, we discuss the implications for the relationship between the life sciences community and society in Japan that may result from this ambiguity in the terminology. It is suggested that, in Japanese life sciences, efforts by individual researchers to make their scientific information unambiguous and explanative are necessary.

The creation of a scientific culture through the experiences that can be offered in a museum is the central theme in the training of guides at Universum. Emphasising the social importance of science democratisation, providing the public with the chance to enjoy science itself, conceiving it as a human creation of extreme beauty, giving it the chance to be appreciated and enjoyed, presenting it from the different fields where an approach to it is possible, is something difficult to achieve outside a science museum and impossible without the intervention of the anfitriones.

The initiatives focusing the professional development of explainers are multiplying around the world, building an informal network of researchers, museums managers and directors, explainers, and regional/continental networks, as THE group, the Thematic Human Interface and Explainers group of Ecsite.The Workshop Sul-Americano de Mediação em Museus e Centros de Ciência e Escola de Mediação em Museus e Centros de Ciência, which took place in Rio de Janeiro in September 2008, was a further important step along this path. We believe it is worthwhile to offer to Jcom readers some of the workshop contributions concerning the training of explainers, to which we added an overview of the general problem presented by Lynn Uyen Tran (Lawrence Hall of Science at the University of California, Berkeley).

This article seeks to reflect on mediation in museums based on experiences that occurred in the “Learning in order to Teach” Project.  In this case, the mediation acquires specific characteristics because it deals with young deaf people learning art-related contents in order to teach other youth in their first language.  The most interesting aspect of this encounter between museum and deaf culture is a mutual, immediate and highly visible influence.  While museum-goers and professionals understand that the “gestures” used by the deaf are not random (rather, on the contrary, they make up a complex language), new signs are created by the students based on the contents that are worked with and discovered in the museum.  These new signs thus enrich the language itself and begin to circulate within the community.

This paper discusses three mediation concept approaches and, consequently, three facets of mediator action.  The approaches presented start with a bibliographical review of the concept of mediation present in education and scientific communication studies.  These approaches serve as a basis for interpreting a semi-directive interview with the director of the Museum of Morphological Sciences of the Federal University of Minas Gerais (UFMG).  They also help us reflect on the complexity of organizing the objectives of a museum action that takes into account the transformational role of the meaning of objects in interaction with different socio-cultural subjects.  In conclusion, the museum's purpose in organizing a museum action using socio-cultural mediation approach and with the mediator as a passeur libre among exhibit objects and visitors is highlighted.

Explainers have a longstanding presence in science museums and centres, and play a significant role in the institutions’ educational agenda. They interact with the public, and help make visitors’ experiences meaningful and memorable. Despite their valuable contributions, little research attention has been paid to the role and practice of these individuals. From the limited research literature that does exist, we know that museum educators employ a complexity of skills and knowledge. We also know such educators have a variety of experiences and qualifications – this creates a rich diversity within the field. Finally we know that the content and quality of programmes designed to educate novice explainers vary across institutions. Should we work toward a shared identity across institutions? Or even a “professionalization”? The paper explores the state of the art of the discussion around that questions.
