results multiple regression analyses showed that motives and maternal overprotection were the main predictors of problematic facebook use symptoms in both genders. mediation analyses suggested that borderline personality traits and overprotection played different roles in the development of problematic facebook use symptoms. in females, borderline traits were a mediator in the relation between ...

This paper studies the notion of ability and its relation with the notion of action in a multi-agent context. It introduces the distinction between two notions respectively called “theoretical ability” and “ability”. The main contribution of this paper is a model of these notions in the Situation Calculus.

Spoken dialogue systems promise eecient and natural access to a large variety of information sources and services from any phone. However, current spoken dialogue systems are deecient in their strategies for preventing, identifying and repairing problems that arise in the conversation. This paper reports results on automatically training a Problematic Dialogue Predictor to predict problematic h...

Agent supervision is a form of control/customization where a supervisor restricts the behavior of an agent to enforce certain requirements, while leaving the agent as much autonomy as possible. This is done in a setting based on the situation calculus and a variant of the ConGolog programming language that is situation-determined, i.e., the remaining program is a function of the action performe...

This paper introduces GLAM, a system based on situation calculus and meta-rules, which is able to provide adaptation by means of selection of actions. It is primarily designed to provide adaptive navigation. The different levels of conception, related to different aspects of the available metadata, are split in different layers in GLAM, in order to ease the conception of the adaptation system a...

We present first ideas on how results about qualitative spatial reasoning can be exploited in reasoning about action and change. Current work concentrates on a line segment based calculus, the dipole calculus and necessary extensions for representing navigational concepts like turn right. We investigate how its conceptual neighborhood structure can be applied in the situation calculus for reaso...
