Bonabeau hierarchy models revisited

Bonabeau hierarchy models revisited

What basic processes generate hierarchy in a collective? The Bonabeau model provides us a simple mechanism based on randomness which develops self-organization through both winner/looser effects and relaxation process. A phase transition between egalitarian and hierarchic states has been found both analytically and numerically in previous works. In this paper we present a different approach: by...

”Antiferromagnetism” in social relations and Bonabeau model

We here present a fixed agents version of an original model of the emergence of hierarchies among social agents first introduced by Bonabeau et al. Having interactions occurring on a social network rather than among ’walkers’ doesn’t drastically alter the dynamics. But it makes social structures more stable and give a clearer picture of the social organisation in a ‘mixed’ regime.

Deviation Models Revisited

Tasks like diagnosis, failure-modes-and-effects analysis (FMEA), and therapy proposal involve reasoning about variables and parameters deviating from some reference state. In model-based systems, one tries to capture this kind of inferences by models that describe how such deviations are emerging and propagated through a system. Several techniques and systems have been developed that address th...

New Care Models revisited

This Issue of LJPC (9.2) is deliberately short, to complement a Virtual Issue on New Care Models, also presented in March 2017. The Virtual Issue highlights 18 previously published LJPC papers that have explored different aspects of integrated care and health promotion at local, community level. These papers will support discussions at the 30 March 2017 London City Health Conference, hosted by ...
