Dynamic model,   regional economy,   innovation.   This paper presents a normative balance mathematical model of regional economy that contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. A method for estimation of the model parameters by application of parallel computations on multi-processors systems is presented. It is determined the...

The environment is an essential component of multi-agent systems, which is often used to coordinate the behaviour of individual agents. Recently many programming languages have been proposed to facilitate the implementation of such environments. This extended abstract is motivated by the emerging programming languages that are designed to implement environments in terms of normative concepts su...

Normative systems in a multiagent system must be able to evolve over time, for example due to actions creating or removing norms in the system. The only formal framework to evaluate and classify normative system change methods is the so-called AGM framework of theory change, which has originally been developed as a framework to describe and classify both belief and normative system change. Howe...

We consider the problem of updating a multi-agent system with a set of conditional norms. A norm comes into effect when its condition becomes true, and imposes either an obligation or a prohibition on an agent which remains in force until a state satisfying a deadline condition is reached. If the norm is violated, a sanction is imposed on the agent. We define a notion of a normative update of a...

This study examines influence and IT in group polarization. Group polarization is the tendency of group members to shift their initial positions to a more extreme direction following discussion. We hypothesize that informational influence is relatively more important than normative influence in causing group members to shift their positions and that IT can be used to enhance the effects of info...

People taking part in argumentativedebates through collective annotations face a highly cognitive taskwhen trying to estimate the group’s global opinion. In order to reduce this effort, we propose in this paper to model such debates prior to evaluating their “social validation.” Computing the degree of global confirmation (resp. refutation) enables the identification of consensual (resp. contro...

This article identifies four factors for consideration in norms-based research to enhance the predictive ability of theoretical models. First, it makes the distinction between perceived and collective norms and between descriptive and injunctive norms. Second, the article addresses the role of important moderators in the relationship between descriptive norms and behaviors, including outcome ex...

Consent to perform a small favor increases a respondent's susceptibility to perform a relatively large favor. This phenomenon, known as the foot-in-the-door effect, is considered to result from induced self-perception changes: the respondent comes to feel helpful for doing the small favor and complies again later out of a desire to maintain the instilled self-view. This study did not find a lin...
