The co-ordination language Linda has been used for parallel processing for many years. Linda uses a shared tuple space and a number of primitives to provide access to the tuple space and thereby enabling communication between processes executing concurrently. Linda provides asynchronous communication between processes, but synchronous access between the processes and the tuple spaces. The Bonit...

Software engineering is based on many interdependent processes involving many interacting stakeholders with conflicting interests and points of view. The management of dependencies between stakeholders activities corresponds to the co-ordination process. This process plays a key role in software engineering notably because of the large use of networks, distributed computing and groupware techno...

Normal subjects and Parkinsonian patients performed a bimanual load lifting task. In this task, one "postural" forearm, held in a horizontal position while supporting a 1 kg weight, was unloaded either by the experimenter's hand (imposed unloading) or by the subject's other hand in response to a tone burst (voluntary unloading). The variables recorded were reaction time (RT: time interval betwe...

In this paper we describe the concept of mobile coordination , a general purpose approach to overcoming failure of agents when using distributed tuple spaces. We demonstrate why mobile coordination is better than using existing techniques such as transactions, how mobile coordination can provide extra functionality in the form of agent wills, and how the framework to provide this can be impleme...

Temperament is the tendency to express particular emotions with a certain intensity that is unique to each individual child. Although temperament seems to be biologically based, learning to regulate emotional expressions depends on caregiver input and socialization. Part of this process involves forming a trusting relationship with the infant so that he or she learns to rely on the parents to h...
