JASSSJournal of Artificial Societies and Social Simulation: For the exploration and understanding of social processes by means of computer simulationIs Religion an Evolutionary Adaptation- (Found July 2, 2008 ) James Dow: Religious people talk about things that cannot be seen, stories that cannot be verified, and beings and forces beyond the ordinary. Perhaps their gods are truly at work, or perhaps in human nature there is an impulse to proclaim religious knowledge. If so, it would have to have arisen by natural selection. It is hard to imagine how natural selection could have produced such an impulse. There is a debate among evolutionary scientists about whether or not there is any adaptive...http://jasss.soc.surrey.ac.uk/11/2/2.html Review of: Agent-Based Modelling and Simulation in the Social and Human Sciences- (Found July 2, 2008 ) Review of: Agent-Based Modelling and Simulation in the Social and Human Sciences by Phan, Denis, and Amblard, Frdric (Eds.), reviewed by Magda Fontanahttp://jasss.soc.surrey.ac.uk/11/2/reviews/fontana.html Review of: Agent-Based Models- (Found July 2, 2008 ) Review of: Agent-Based Models by Gilbert, Nigel, reviewed by Gianluca Manzohttp://jasss.soc.surrey.ac.uk/11/2/reviews/manzo.html Review of: Social Simulation: Technologies, Advances and New Discoveries (Premier Reference)- (Found July 2, 2008 ) Review of: Social Simulation: Technologies, Advances and New Discoveries (Premier Reference) by Edmonds, Bruce, Hernandez, Cesareo and Troitzsch, Klaus G., reviewed by Scott E. Pagehttp://jasss.soc.surrey.ac.uk/11/2/reviews/page.html A Model-To-Model Analysis of Bertrand Competition- (Found July 2, 2008 ) Xavier Vil: This paper studies a version of the classical Bertrand model in which consumers exhibit some strategic behavior when deciding from what seller they will buy. We use two related but different tools. Both consider a probabilistic learning (or evolutionary) mechanism, and in the two of them consumers' behavior influences the competition between the sellers. The results obtained show that, in general, developing some sort of loyalty is a good strategy for the buyers as it works in..http://jasss.soc.surrey.ac.uk/11/2/11.html Towards a Community Framework for Agent-Based Modelling- (Found July 2, 2008 ) Marco A. Janssen, Lilian Na'ia Alessa, Michael Barton, Sean Bergin and Allen Lee: Agent-based modelling has become an increasingly important tool for scholars studying social and social-ecological systems, but there are no community standards on describing, implementing, testing and teaching these tools. This paper reports on the establishment of the Open Agent-Based Modelling Consortium, www.openabm.org, a community effort to foster the agent-based modelling development, communication, and...http://jasss.soc.surrey.ac.uk/11/2/6.html Micro- and Macro-Level Validation in Agent-Based Simulation: Reproduction of Human-Like Behaviors and Thinking in a Sequential Bargaining Game- (Found July 2, 2008 ) Keiki Takadama, Tetsuro Kawai and Yuhsuke Koyama: This paper addresses both micro- and macro-level validation in agent-based simulation (ABS) to explore validated agents that can reproduce not only human-like behaviors externally but also human-like thinking internally. For this purpose, we employ the sequential bargaining game, which can investigate a change in humans' behaviors and thinking longer than the ultimatum game (i.e., one-time bargaining game), and compare simulation results of...http://jasss.soc.surrey.ac.uk/11/2/9.html Differential Equation Models Derived from an Individual-Based Model Can Help to Understand Emergent Effects- (Found July 2, 2008 ) Sylvie Huet and Guillaume Deffuant: We study a model of primacy effect on individual's attitude. Typically, when receiving a strong negative feature first, the individual keeps a negative attitude whatever the number of moderate positive features it receives afterwards. We consider a population of individuals, which receive the features from a media, and communicate with each other. We observe that interactions favour the primacy effect, compared with a population of isolated individuals. We...http://jasss.soc.surrey.ac.uk/11/2/10.html Horizontal and Vertical Multiple Implementations in a Model of Industrial Districts- (Found July 2, 2008 ) Ugo Merlone, Michele Sonnessa and Pietro Terna: In this paper we discuss strategies concerning the implementation of an agent-based simulation of complex phenomena. The model we consider accounts for population decomposition and interaction in industrial districts. The approach we follow is twofold: on one hand, we implement progressively more complex models using different approaches (vertical multiple implementations); on the other hand, we replicate the agent-based simulation with different.http://jasss.soc.surrey.ac.uk/11/2/5.html Using the ODD Protocol for Describing Three Agent-Based Social Simulation Models of Land-Use Change- (Found July 2, 2008 ) J. Gary Polhill, Dawn Parker, Daniel Brown and Volker Grimm: This article describes three agent-based social simulation models in the area of land-use change using a model documentation protocol, ODD, from the ecological literature. Our goal is to evaluate how well fitted it is to social simulations and how successful it might be in increasing communication between individual- and agent-based modellers. Such shared protocols can facilitate model review, comparison, and replication. We initially.http://jasss.soc.surrey.ac.uk/11/2/3.html |
