In this paper we analyse how different communication media affect, restrict and facilitate business actions. This paper aims to attain a further understanding of what consequences decisions about offering or relinquishing a certain medium would have for the company and its customers. We are also interested in finding feasible ways to make such analyses of business actions and communication medi...

Principled game-theoretic techniques exist for solving the problem of action coordination in a group of agents, however they typically suffer from an exponential blowup of the action space when many agents are involved. Coordination graphs (Guestrin et. al., 2002) offer tractable approximations via a context-specific decomposition into smaller coordination problems, and they are based on an ite...

Coordination and cooperation are crucial notions in multi-agent systems. We provide a constraint programming language called GrAPL, with facilities for group communication, group formation and group collaboration. GrAPL includes three novel statements. Two of these enable groups of agents to communicate about possible constraints on a specific action they might do together. If the demands of th...

This study aimed at discussing and representing discourse analysis of classroom talk in two contexts. It is significant, since it considers different genres of talk, cultural and social identities, social relations, different ideologies and many other aspects in this analysis. It attempts to analyze the dominant classroom patterns in two contexts. Two cases of study were analyzed in this study:...

When interacting with people with aphasia, communication partners use a range of subtle strategies to scaffold, or facilitate, expression and comprehension. The present article analyses the unintended effects of these ostensibly helpful acts. Twenty people with aphasia and their main communication partners (n = 40) living in the UK were video recorded engaging in a joint task. Three analyses re...
