With the expansion of connected devices (tablets, smartphones, etc.), a leap in multiplatform technologies is occurring, bringing about changes in many areas of the communications professions. In this context, values based on flexible, multiplatform, cooperative work that takes the audience into consideration are increasingly important. Professional photography coexists with — and is even rivaled by — images taken by citizens, which are often used by the mass media. For that reason the need is greater than ever for photographers and graphic professionals who, in one way or another, adapt to the new media Using a multiple case study method, this article examines the digital resources used by photographers who have won a World Press Photo Award. It studies the ways in which they exploit the medium, extending the photographic narrative beyond the website, to promote themselves and their personal brand. The results show photographers’ preference for unidirectional communication models and superimposed strategies that have limited engagement and viralisation. The acquisition of digital expertise by photojournalists is at an intermediary stage, since the cases analyzed reveal that these professionals’ web 2.0 activity is limited or underexploited.

This paper is a proposal for a methodologically based monitoring of the changes in habits and needs of library audiences, i.e. changes in access to library services, in the circumstances of the changed communication models caused by the wide use of information and communication technology. It presents audience research in the context of strategic planning in libraries, and points out terminological categories that could serve as a starting point for further research. Using the case study method of Novi Sad City Library, the paper categorizes the audience in two groups which proved to be right for quantitative and qualitative monitoring: according to the preference of the audience for certain content - permanent, occasional, potential and inaccessible audience types are defined, and according to the methods of addressing - users of funds and services, audiences in the narrow sense and online users are defined. Young people turned out to be a strategically relevant target group. The research has shown that the youth are the widest digital media consumers and that their primary goal is infotainment - a combination of a low percentage of information in highly entertaining packages. Members of young population do not recognize the library as a place of interest, so it is necessary to develop adequate channels of communication with them, in a way typical for this group. The paper shows how the model of the Novi Sad Library can be applied as a strategically based audience research in other public libraries, and gives an example of a user experience testing model (UX) and its final result - designed library services. Previous researches by Leo Appleton and Gina De Alwis were used in the paper. At the core of the designed service is participation, as a model of creating instead of consuming the prepared content.

In recent years, increasing criticism has been levelled against case study based research on public engagement and participation in science and technology (PEST). Most critics argue that such case studies are highly contextual and fail to provide global, holistic and systemic views of public engagement phenomena. In this study, we mapped the case study literature on PEST by identifying a robust sample of articles, and analysed it looking for emerging patterns that could provide empirical evidence for new frameworks of public engagement design and analysis. Results show that the case study based literature on PEST continues to grow, although concentrated in a few countries and knowledge domains. The trends that emerged from the sample reveal high centralisation and planning and suggest that deficit science communication models are still common. We argue that future frameworks may focus on decentralising hierarchical power and dependency relationships between agents.

Abstract This paper offers a case study of three selected ecovillages (two in Hungary and one in Slovakia). The main objective is to characterize, analyse and eventually compare types, trends and problems in the development of ecovillages and to discuss the possible impacts and effects of ecovillage movement on sustainable rural development. The authors used interviews, observation and inquiry for data collection and methods of document analysis, content analysis of different sources, and analysis of foot marks. They attempt to bring the worldview closer by introducing the basic ecovillage concept and framework, and by describing the ecovillage types, recent trends, problems and challenges. The analytical part begins with a short characteristic of the ecovillage movement in Hungary and Slovakia and follows with six thematic subchapters that investigate and compare the observed ecovillages according to the purposes and motivation for their founding, the communication models and public relations, local economic systems and self-sufficiency phenomenon, the employment structure and the existing infrastructure. Finally, the last part is devoted to assess the main research findings.
