Computer Supported Cooperative Work (CSCW) is an interdisciplinary research area devoted to exploring the issues of designing computer-based systems that enhance the abilities to cooperate and integrate activities in an efficient and flexible manner for people in cooperative work situations. This volume is a rigorous selection of papers that represent both practical and theoretical approaches to CSCW from many leading researchers in the field. As an interdisciplinary area of research, CSCW brings together widely disparate research traditions and perspectives from computer, human, organisational and design sciences. The papers selected reflect a variety of approaches and cultures in the field. Audience: Of interest to a wide audience because of the huge practical impact of the issues and the interdisciplinary nature of the problems and solutions proposed. In particular: researchers and professionals in computing, sociology, cognitive science, human factors, and system design.

th This volume gathers together the technical papers presented at the 8 European Conference on Computer Supported Cooperative Work (ECSCW), held in Helsinki Finland. ECSCW is an international forum for multidisciplinary research covering the technical, empirical, and theoretical aspects of collaboration and computer systems. The 20 papers presented here have been selected via a rigorous reviewing process from 110 submissions. Both the number of submissions and the quality of the selected papers are testimony to the diversity and energy of the CSCW community. We trust that you will find the papers interesting and that they will serve to stimulate further quality work within the community. The technical papers are complemented by a wider set of activities at ECSCW 2003, including tutorials, workshops, demonstrations, videos, posters and a doctoral colloquium. Together these provide rich opportunities for discussion, learning and exploration of the more recent and novel issues in the field. This conference could not have taken place without considerable enthusiasm, support and participation, not to mention the hard work of a number of people. In particular, we would like to thank the following: * The authors, representing over 17 countries and 97 institutions, who submitted a paper. So many submissions of such high quality are the basis of a good conference. * The members of the program committee who so diligently reviewed and discussed papers. Their collective decisions result in a good scientific program and their feedback to authors strengthens the work of the community.

Schmidt and Bannon (1992) introduced the concept of common information space by contrasting it with technical conceptions of shared information: Cooperative work is not facilitated simply by the provisioning of a shared database, but rather requires the active construction by the participants of a common information space where the meanings of the shared objects are debated and resolved, at least locally and temporarily. (Schmidt and Bannon, p. 22) A CIS, then, encompasses not only the information but also the practices by which actors establish its meaning for their collective work. These negotiated understandings of the information are as important as the availability of the information itself: The actors must attempt to jointly construct a common information space which goes beyond their individual personal information spaces. . . . The common information space is negotiated and established by the actors involved. (Schmidt and Bannon, p. 28) This is not to suggest that actors' understandings of the information are identical; they are simply "common" enough to coordinate the work. People understand how the information is relevant for their own work. Therefore, individuals engaged in different activities will have different perspectives on the same information. The work of maintaining the common information space is the work that it takes to balance and accommodate these different perspectives. A "bug" report in software development is a simple example. Software developers and quality assurance personnel have access to the same bug report information. However, access to information is not sufficient to coordinate their work.

The emergence of network facilities and the increased availability of personal computer systems over the last decade has seen a growing interest in the use of computers to support cooperative work. This volume contains the proceedings of the sixth European Conference on Computer Supported Cooperative Work (CSCW), a multi-disciplinary area which embraces both the development of new technologies and an understanding of the relationship between technology and society. These proceedings present a collection of papers that encompass activities in the field, treating such subjects as virtual environments, uses of the Internet, studies of cooperative work and emerging models, studies of groupware systems in use in real-world settings, and theories and techniques to support the development of cooperative applications. The articles feature emerging technologies alongside new methods and approaches to the expansion of this important class of applications. Audience: This work reflects the best of the current research and practice within CSCW. It will appeal to both researchers and practitioners whose work involves computer and information science, human-computer interaction, information systems, hypermedia, organisational/social informatics and social studies of science and technology.

Computer-Supported Cooperative Work (CSCW) is an interdisicplinary research area devoted to exploring the issues of designing computer-based systems that enhance the abilities of cooperating workers to coordinate and integrate their activities in an efficient, effective, and flexible manner. This rigorously selected volume represents both practical and theoretical approaches from many of the leading researchers in the field. As an interdisciplinary area of research, CSCW is characterized by bringing together widely disparate research traditions and perspectives into an arena of collaboration and contention. The selected papers reflect the diverse approaches and cultures of this multi-disciplinary field. This collection will be of interest to a wide audience - because of the huge practical import of the issues and because of the interdisciplinary nature of the problems and the solutions proposed. In particular, the volume will be of interest to researchers and professionals in computing, sociology, cognitive science, and human factors.

The European Court of Justice (ECJ) has played a vital role in promoting the process of European integration. In recent years, however, the expansion of EU law has led it to impact ever more politically sensitive issues, and controversial ECJ judgments have elicited unprecedented levels of criticism. Can we expect the Court to sustain its role as a motor of deeper integration without Member States or other countervailing forces intervening? To answer this question, we need to revisit established explanations of the Court's power to see if they remain viable in the Court's contemporary environment. We also need to better understand the ultimate limits of the Court's power - the means through which and extent to which national governments, national courts, litigants and the Court's other interlocutors attempt to influence the Court and to limit the impact of its rulings. In this book, leading scholars of European law and politics investigate how the ECJ has continued to support deeper integration and whether the EU is experiencing an increase in countervailing forces that may diminish the Court's ability or willingness to act as a motor of integration. This book was published as a special issue of the Journal of European Public Policy.

On being asked to write a book on migration and homing in animals, intended as an introductory text to inform and stimulate both students and non-specialists, I saw the following alternatives for an outline: (1) I could discuss known or hypothetical mechanisms of orientation, and enumerate animals known or thought to use these mechanisms in migration and homing. (2) I could discuss the known feats of orientation by animals under field observation (e. g. migration), following some practic able order, with a subsequent discussion of the attempts at and possible success in elucidating the basic mechanisms of orientation. Both alternatives have obvious disadvantages. (1) would suffer from the fact (a) that very few orientation mechanisms (such as the sun, star, or magnetic compass) have been firmly established and (b) that for many animals the modes of orienta tion are unknown; therefore, for many animals whose consider able feats of orientation are well known, an appropriate alloca tion could not be made. With (2) the disadvantage is that due to the complexity of animal movements, it is difficult to find some relevant order and that in many animal groups discussions of certain known mechanisms such as the sun com pass would recur. I have selected outline (2) as the much lesser evil. The discussion pursues a compromise between taxonomic order and similarity in feats of orientation or methodological approaches chosen by the various investigators."

Computer-Supported Cooperative Work (CSCW) has emerged as a new interdisciplinary forum for research into the issues central to the design, implementation and use of technical systems which support people working cooperatively. This rigorously selected volume of papers contains both practical and theoretical approaches from many of the leading researchers in the field. This collection necessarily emphasises European research, where many of the initiatives in CSCW originated. However, the papers have been selected for international appeal and many international contributions from, for example, leading researchers in the United States and Japan are also included. This collection will be of interest to a wide audience because of the interdisciplinary nature of the problems and solutions proposed. These include the human and information sciences generally, cognitive scientists, psychologists, and allied technologists and social scientists.

This 1978 volume contains papers from contributors to the Third International Conference on Comparative physiology. The Conference selected particular areas for examination. In the first section of this volume the problems of how animals can take up water vapour from the atmosphere are considered as well as advances in studies of how water movements across epithelia are generated by solute movements. The second section deals with how a wide variety of animals, both invertebrate and vertebrate, living under stress in ionically unbalanced environments cope with the unusual difficulties of ionic regulation. In the final section biologists and physicists examine the role of fluid mechanics in biology. Both the theoretical basis of the hydrodynamics and aerodynamics and the biological investigations on the variety of fluid flows encountered inside and around organisms are presented.
