The 4th edition of the Collaborative Technologies 2013 (CT) International Conference was hosted in Prague, Czech Republic, during 24 to 26 July, 2013 and was co-organised by The University of Economics in Prague (VŠE), Czech Republic. This conference was part of the IADIS Multi Conference on Computer Science and Information Systems 2013, 22 - 26 July.

This CT Conference is focused on issues related to the concepts, theory, modelling, specification, implementation and evaluation of collaborative systems, technologies and their 'wider' applications in the information society. It pays particular attention to the 'wider' dimension as a mean to diversify it and broaden the applicability and scope of the current body of knowledge in the area of applied collaborative domain including emerging and next generation methods and technologies. The aim is to cover both technical and non-technical aspects of the collaborative nature of today's information society, as well as, prompt future direction for the advancement of the community.

Submissions were accepted under the following 5 main topics:
- Theory Foundations
- Technical Infrastructures
- Environments, Tools and Applications
- Benefits realization and Social Implications
- Future Concepts

The Collaborative Technologies 2013 Conference had 38 submissions from more than 11 countries. Each submission has been anonymously reviewed by an average of four independent reviewers, to guarantee the final high standard of the accepted submissions. Consequently only 6 full papers were approved which corresponds to an acceptance rate of 16 %. A few more papers were accepted as short and reflection papers.

The Conference Program featured an opening and closing sessions, 3 parallel paper sessions, 1 Keynote Presentation and a Poster Session.

The keynote presentation was given by Professor Gunilla Bradley, Professor Emerita, Royal Institute of Technology, Sweden.

Extended versions of the best papers were selected to be published as extended versions in the the International Journal of Distributed Systems and Technologies (IJDST) ISSN: 1947-3532. Other outlets may also receive extended versions of the best papers, including journals from Inderscience.

Keynote presentation

"WHAT IS QUALITY OF LIFE IN THE ICT SOCIETY?''
by Professor Gunilla Bradley,

Professor Em, Royal Institute of Technology, Sweden

Abstract

Some issues that will be addressed are:

• Main changes in people´s lives – structures and roles. What changes are going on in the professional, private and citizen's role? How can we balance our various roles at the increasing convergence of them? Important contributing factors to Quality of Life and how to achieve.

• Main changes in the labour market – work force in the so-called flexible companies. New ways to influence our work life conditions as well as to contribute to societal change.

• Impact of network organizations on human behavior, values, motivation and feelings. Our relation to space and time, what kind of stress? Dialectics of values and life styles.

• Some trends in psychosocial communication and ICT, collaboration and global communication patterns. The home as a communication sphere in the network era - new opportunities and risks.

• Convergence and acceleration are main processes at the interplay between technology, societal structure, organizational design, and human roles in the society. I will reflect on the convergence theory and the discourse in Media Technology and Informatics about the present power relations and movements globally. I will present reflections on risks and opportunities in the 21 st Century ICT society. Where are the "energy centers" that can activate and create changes towards the "Good Information Society"? Can agreements on Goals and Visions for that society be achieved?

The Collaborative Technologies 2013 was published in Book (ISBN: 978-972-8939-92-2).
