A feature of the management of natural resources in the coastal zone is that it involves multiple stakeholders. It has been suggested that the effectiveness of coastal management relies on the cooperation of this multitude of stakeholders in decision-making. This study reports on the findings of an investigation into the modes of interaction used by coastal researchers to communicate with stakeholders. A qualitative research methodology was used through both telephone and in-depth face-toface interviews to elucidate the mechanisms of interaction and, in turn, produce a typology of interaction modes. It was found that there were five main modes of interaction: Limited; Mediator Achieved; Key Stakeholder; Full Interaction and Mixed and that the discipline area in which the researcher worked did not dictate their preferred mode of interaction. It was concluded that although there are a number of limitations to effective participation, these interactions have significant implications for meaningful participation in the management of coastal resources.

Natural parks are a place where science communicates with the public, involving dimensions ranging from the knowledge of living species to the relationship between man and nature, the environmental policy decisions and the anthropic impact assessments. Natural parks are therefore an important arena for scientific communication where the "shared participation" tools play a fundamental role. To this end, we report a few international experiences that illustrate the role of the interest holders and the importance of coordination of the parties involved in the management of parks.

The concept of a biosphere reserve was adopted by UNESCO, within the MAB Programme, launched in 1971, in order to promote and to demonstrate the harmonious relationships that should exist between people and the environment and, particularly, to promote a harmonization model of the environmental protection needs with those of the sustainable economical-social development. All the international conventions, the management and action plans accomplished in order to achieve the sustainable development objectives underline the great importance to establish a constructive dialogue, with impact on the long term decisions, between the decision makers and the wide public (especially with the local population).

The eighth convention of the PCST (Public Communication of Science and Technology) network, which took place in Barcelona this June, emphasised an increasing richness in reflection and practice with regard to several themes to do with science communication. This growing variety mirrors the different approaches gradually coming about in different cultural and geographical contexts. In particular, the Focus of this issue of JCOM concentrates on a presentation of the models of interpretation of science communication referring to the Mediterranean and South American cultural area.

I would like to start with a brief news item in the August 1999 issue of National Geographic which gives some food for thought: "With 5,000 climbing routes, such as Double Dogleg and Walk on the Wild Side, California's Joshua Tree National Park attracts about 140,000 enthusiasts a year to test their skill on granite boulders. But some visitors view their metal bolts as defacements hammered into rocks.

In The Areopagitica, his most important work of prose, John Milton mentions Galileo as the illustrious martyr who fought for the freedom of thought. The name of the great scientist is repeated several times in the English poet's epic masterpiece: Paradise Lost. In three different passages of the poem, Milton in fact celebrates the "Tuscan Artist" and his crucial achievements in astronomy. Nevertheless, in a subsequent passage, the poet addresses the Copernican issue without openly defending the heliocentric theory confirmed by Galileo's discoveries. In fact, he neither embraces the Copernican system nor the Ptolemaic one, but instead compares them, following a dialectic method where one cannot fail to notice an echo of Galileo's Dialogue Concerning the two Chief World Systems. Milton's literary work presents images of astronomy at that time, thus offering a valuable historical example of scientific communication through art.

Halliday has demonstrated that changes in discourse function covary with changes in the grammatical resources a language makes available to construe discourse. Specifically, he outlined the ways in which nominalisation evolved as a resource for construing scientific reality as a world of logical relations among abstract entities. In the present article,

The use of photography in the field of psychiatry is an eloquent example of the complex evolution of the relationship between science, communication and society. The research that follows analyses the development of such a relationship in a crucial period of the history of psychiatry: the 1970s. That was the time that witnessed the revolution of a science which admitted the failure of its methods and "instruments", mental hospitals. That was also the time when a profound change took place in the communicative methods of photography related to this uncertain field of knowledge. A group of photographers, driven by the political situation of the time, covered the end of mental hospitals.

Free information works. In the sense that Open Access Journals, scientific journals which can be accessed at no cost, thereby guaranteeing free access to everyone, are at the same time able to guarantee the same quality as –or even better than- that of traditional journals, which can only be read by those willing to pay a price, be it the cover price or a subscription.

The problem of accessing data is as old as science itself. Complete popularisation of scientific data (of a theoretical model), and even more so of the methods and materials used during an experimental process and of the empirical data amassed, has always been considered an essential part of the process of authentication, duplication and filing of scientific knowledge. It is also true, however, that this theory has always been a complex riddle with no simple solution. Strangely enough, in today's era of instant communication, the challenge of information access seems to be facing new, daunting obstacles, some of which have the same name and characteristics they had 100 or 300 years ago, but which have been intensified by new dimensions and unexpected corollaries. Others have a new core, an example being, the problem related to disclosure, which implies the (more or less) complete popularisation of the data, procedures, and tools used during research. This is a subject which, although ancient in form, has recently taken on new, far-reaching implications. The scientific community now has to face a problem which originated, first, with the sequencing of the human genome and, later, with that of certain types of rice; a problem which could redefine certain aspects of the epistemological practice and nature of science.
