This paper presents an agent based model of the evolution of cooperation in a complex environment. Anthropoid agents reproduce sexually, and live in a world where food is irregularly distributed in space and seasonally produced. They can share food, form hunting and migrating groups, and are able to build alliances to dispute territory. The agents memorize their interactions with others and the...

This paper deals with the design and implementation of AMICO1 , a prototype to enhance mathematics learning by interactions between a student (or a dyad) and virtual agents (several co-learner companions and a mathematician). This work is part of a multidisciplinary project, the project LINGOT that aims to give math teachers tools to improve their teaching. We first present the foundations of t...

Project work is becoming an important part of university education aiming at preparing students for team-based activities in a workplace. However, cooperation problems are common in the learning process. The major purpose of this paper is to address these challenges by applying Second Life a as a platform for learning how cooperation can be supported by technology. Threedimensional Collaborativ...

Cooperation requires sharing data, but enforcing access restrictions across enterprises is a challenge. Different sites have different policies and use a variety of access control methods that are tailored to the individual enterprises’ needs. Mapping one set of rules into another may require complex computations, possibly with a separate method for each pair of sites. This paper proposes an in...

Twocross-sectional studies investigated the effects of competition andcooperationwith virtual players on exercise performance in an immersive virtual reality (VR) cycle exergame. Study 1 examined the effects of: (1) self-competition whereby participants played the exergamewhile competing against a replayof theirprevious exergame session (Ghost condition), and (2) playing the exergame with a vir...

BACKGROUND Teamwork is important for patient care and outcome in emergencies. In rural areas, efficient communication between rural hospitals and regional trauma centers optimise decisions and treatment of trauma patients. Little is known on potentials and effects of virtual team to team cooperation between rural and regional trauma teams. METHODS We adapted a video conferencing (VC) system t...

Human-computer interaction has entered the 3D era. The most important models representing spatial information — maps — are transferred into 3D versions regarding the specific content to be displayed. Virtual worlds (VW) become promising area of interest because of possibility to dynamically modify content and multi-user cooperation when solving tasks regardless to physical presence. They can be...

In this paper the aspects of a Virtual Enterprise (VE) that are essential for the design of cooperation technology for a VE are identified. The explorative approach taken in Computer Supported Cooperative Work (CSCW) research is introduced and three CSCW topics are discussed that can be applied for the solution of problems inherent to a VE. Cooperative Technology for Virtual Enterprises Due to ...

An international cooperation between educators in Australia and the US has led to a reconceptualization of the teaching of a library science course at Appalachian State University. The pedagogy of Action Learning coupled with a 3D virtual learning environment immerses students in a social constructivist learning space that incorporates and supports interaction and reflection. The intent of this...

We completed the implementation of a broadband kernel, a flexible open programma-ble networking platform, for creating, deploying and managing sophisticated next generation multimedia services called xbind. xbind currently supports the creation, deployment and management of networked multimedia services (e.g. The building blocks of the broadband kernel consist of a set of objects typically mode...
