In sinmlating a consultant's role, a central capahility of WISBER is reasoning about the eonversants' intentions to determine a communicative action that is likely to achieve progress towards a longterm consultation goal [Gerlach, Horacek 1989]. The mental model of tile agents involved consists of BEI, IEFs, KNOWs, aud WANTs, which are expressed as I)rimitive, time-dependent states. An agent's ...

The language/action perspective (LAP) as orginally introduced by Winograd and Flores has inspired several tools and information system design methodologies. The goal of this article is to make the communication norms underlying various LAP workflow loop models (DEMO, ActionWorkflow) explicit and to contrast them with the auditing norms of internal control. It appears that the communicative acti...

We propose an approach to reasoning about conversation protocols within the framework of a logic-based agent language. We show how to embed a theory of communicative actions in the framework of a modal logic of action and beliefs, to specify software agents that, situated in a multi-agent environment, can interact with one another by a speech act based communication mechanism. Agents have their...

Model checking techniques for communication protocols usually are phrased in terms of processes, basically labelled arcs in a labelled transition system. We propose to lift checking for such protocols to a more abstract level by analysing the protocols as composite communicative actions, with a communicative action viewed as a mapping on an appropriate class of epistemic models. As an example, ...

We propose a mechanism to learn communicative action structure to analyze adversarial reasoning patterns in customer complaints. An efficient way to assist customers and companies is to reuse previous experience with similar agents. A formal representation of customer complaints and a machine learning technique for handling scenarios of interaction between conflicting human agents are proposed....

We investigated 14-month-old infants' expectations toward a third party addressee of communicative gestures and an instrumental action. Infants' eye movements were tracked as they observed a person (the Gesturer) point, direct a palm-up request gesture, or reach toward an object, and another person (the Addressee) respond by grasping it. Infants' looking patterns indicate that when the Gesturer...

Employing a community ecology perspective, this study examines how interorganizational (IO) communication and social capital (SC) facilitated organizational recovery after Hurricane Katrina. In-depth interviews with 56 New Orleans organizations enabled longitudinal analysis and a grounded theory model that illustrates how communication differentiated four phases of recovery: personal emergency,...

The understanding of neuronal circuits has been, and will continue to be, greatly advanced by the simultaneous imaging of action potentials in neuronal ensembles. This protocol describes "bulk" loading of brain slices with acetoxymethyl (AM) ester calcium indicators in order to monitor action potential activity in large populations of neurons simultaneously. The imaging of calcium influx into n...

There is strong evidence that we automatically simulate observed behavior in our motor system. Previous research suggests that this simulation process depends on whether we observe a human or a non-human agent. Measuring a motor priming effect, this study investigated the question of whether agent-sensitivity of motor simulation depends on the specific action observed. Participants saw pictures...

We present a modal logic of belief and announcements in a multi-agent setting. This logic allows to express not only that ψ holds after the announcement of φ as in standard public announcement logic (PAL), but also that the announcement of φ occurs. We use the logic to provide a formal analysis of several concepts that are relevant for multi-agent systems (MAS) theory and applications: the noti...
