This paper addresses theoretically the question how virtual communication may affect cooperation in work teams. To address effects of virtual communication on cooperation, this paper draws on a formal social exchange model proposed by Flache and Macy (1996, Flache 1996). The degree of team virtualization, i.e. the extent to which interaction between team members occurs exlusively online, is rel...

This research presents three studies that investigate the characteristics of the interaction and cooperation activities in immersive and non-immersive virtual environments. The first study explored the characteristics of the interaction during a cooperative task; the second one investigated the characteristics of the cooperation strategies used in the cooperative task; the final one verified if...

Today, medical infrastructures are subject to organisational change the world over. The reasons for this are manifold. On the one hand, it can be observed through scientific innovation and gaining of knowledge that a more in-depth specialisation is taking place, which means that medical healthcare providers are able to offer in-depth knowledge in narrowing fields. On the other hand, through inc...

A “virtual enterprise” results from a temporary agreement among some enterprises, which decide to cooperate together into a given value chain for a limited time horizon. The crucial point in the development of said network is “to search for partners” and organize interactions among firms. In practice, a first problem has to be approached each time a re-organization of the network can be applied...

An energy-efficient virtual multiple-input multiple-output (MIMO) communication architecture based on V-BLAST receiver processing is proposed for energy-constrained, distributed wireless sensor networks. The proposed scheme does not require transmitter-side sensor cooperation unlike previously proposed virtual MIMO schemes for wireless sensor networks. In sensor networks with single-antenna dat...

The complexities of today’s organizations have made it increasingly challenging for leaders to encourage and sustain a culture of cooperation. As organizations become flatter and leaner and people are required to do “more with less,” the key to success is the ability to coordinate decisions and actions across organizational boundaries and gain the support of people who often have competing prio...

This paper presents an approach to automatically compute animations for virtual (human or robot) mannequins cooperating to move bulky objects in cluttered environments. The main challenge is to deal with 3D collision avoidance while preserving the believability of the agents behaviors. To accomplish the coordinated task, a geometric and kinematic decoupling of the system is proposed. This decom...
