As a consequence, there are a couple of restrictions concerning different aspects (e.g. positioning and orientation in the studio) that make Virtual Studio productions complicated and expensive. However, they also offer a wide range of new visual effects and new ways for TV shows that often come up while playing with this technology. Further research can help to overcome the problems of the current architecture and thus Virtual Studios can be an important base for steps towards the digital revolution of broadcast business. The article provides a brief overview of the technology being used so far. It highlights its problems and benefits and gives examples of different TV shows that take advantage of the special features of Virtual Studio systems. Finally, it mentions related research areas.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Among the many support functions enabling efficient cooperation in teams, team decision-making is a very crucial one, but it does not find adequate support in contemporary team software solutions. Even the most knowledgeable results from collective choice theory are not reflected in the respective virtual team environments. This paper makes a systematic attempt to provide virtual teams with the power of voting procedures developed in the context of the theory of collective choice. A toolset called TEAMVOTE, for electronic decision-making, is presented, implementing a blend of the most important collective choice strategies, like the Dodgson rule, the majority rule, plurality voting, Borda counting, approval voting, the Nanson rule, the Hare rule, the Coomb rule, etc., based on standard Internet technology. The services of TEAMVOTE, which are targeted to support goal-oriented business teams in group decision matters, raise the perspective of its use to enable democratic processes on a societal scale.","PeriodicalId":287840,"journal":{"name":"Proceedings.

We describe a system that supports the collaborative construction of indexes of concepts rather than terms. In a concept index, a concept can be described by more than one term, phrase, arbitrary text piece, and other concepts. These concepts can be structured and associated with one another without strict restrictions. Software agents work in the background to find occurrences of concepts in a document collection, enabling users to navigate documents based on concepts. Users can extract concepts by simply highlighting pieces of text while browsing documents. Through collaborative index construction, a user benefits from contributions of other users, and the system enables a group of users to collaboratively manage information.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Team members rarely work on isolated computers; networked computers are commonly used. An underlying assumption of our research is that software engineering teams will work more effectively if adequately supported by network-based groupware technology. This research is investigating the provision of such network-based support for software engineering teams. The immediate objective is to provide WWW-based support, in the form of shared information spaces, specifically for students working on Software Engineering Group (SEG) projects in the Department of Computer Science at Durham. The long term objectives are to develop more flexible support for group working among university students and their staff supervisors for project work. This paper reports on our development and use, over a two year period, of SEGWorld-a WWW based infrastructure incorporating shared information spaces. Hypotheses relating to the student use of the infrastructure and shared information spaces have been formulated. Results of the use of this WWW-based infrastructure are presented.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Activities traditionally constrained by the need for intense information management increasingly involve cooperating organizations. Information management tools and techniques do not scale well in the face of this organizational complexity. Informal sharing, based largely on manual copying of information, cannot meet the demands of the task as size and complexity increase. Formal approaches to sharing information are based on groupware tools, but cooperating organizations do not always enjoy the trust or commonality of sophisticated infrastructure, methods, and skills that this approach requires. The application web is a simple, loosely coupled, highly flexible strategy for information sharing that bridges the gap. Extensive information relevant to different parts of the software life cycle is interconnected in a simple, easily described way; such connections permit selective information sharing by a variety of tools and in a variety of collaboration modes that vary in the amount of organizational coupling they require.","PeriodicalId":287840,"journal":{"name":"Proceedings.

Today's Internet applications include local community networks as well as global business-to-business communication. The more the Internet is becoming a major part of our daily communication infrastructure, the more demands of effective tools for cooperation support arise. We have developed a Web-based groupware system-the BSCW shared workspace system-which aims to satisfy these demands. In this paper we describe a Java-based extension of the BSCW system that has been designed to improve usability of the system. As a consequence of limitations experienced from HTML-based user interfaces we have extended BSCW by a new JBrowser applet that uses XML as a data description language and provides a graphical representation of the user's shared workspaces. It can be seen as an example of how XML and Java can leverage from each other, how XML structures can be incorporated as objects in traditional applications, and how XML can be used to build a communication bridge between object repositories.","PeriodicalId":287840,"journal":{"name":"Proceedings.

A key element of the application server architecture is CORBA, the Common Object Request Broker that allows applications to communicate in a transparent and interoperable manner. For this new architecture to succeed, it must guarantee a secure processing environment to the organisations. This paper explains why a conventional firewall cannot be used to secure CORBA applications. It describes the architecture of CORBAgate, a gateway based on the concept of proxies and object key re-mapping. The paper compares the CORBAgate solution with the OMG specification for CORBA firewall security. Finally, the paper discusses how these elements combine to enable outsourced application services.","PeriodicalId":287840,"journal":{"name":"Proceedings.
