Subject: JASSS: Vol. 5(4) published

The Journal of Artificial Societies and Social Simulation
(http://jasss.soc.surrey.ac.uk/) published the fourth issue of Volume 5
on October 31st.

JASSS is an electronic, refereed journal devoted to the exploration and
understanding of social processes by means of computer simulation. It
is located at <http://www.soc.surrey.ac.uk/JASSS/>. It is freely
available, with no subscription.

In this issue, Deffaunt et al provide new results on the dynamics of
opinion change in a society of agents having continuous (i.e. ranging
over a continuous scale) opinions, exploring the circumstances in
which extreme opinions can spread through a population. Analogies
can be drawn between their results and the influence of early Nazis in
Germany or of radicals in Islam. Stocker et al are also concerned
with opinion dynamics, showing how complex systems models can be used
to investigate the effects of various parameters (including the number
of layers and the number of links per node) in hierarchical and
scale-free network structures. Lepperhoff simulates asynchronous,
computer-mediated negotiations in groups in order to identify the
influence of negotiation parameters such as the duration of the
negotiation, the nature of the task and the voting scheme used. Hales
extends a series of papers on the effects of norms, many of which have
been previously published in JASSS. His focus in this paper is on the
role of the normative reputations of groups (a form of social
stereotyping) and how such reputations might support the maintenance of
social norms that are beneficial to the society as a whole, although in
conflict with individual self-interest. Gatherer models the evolution
and differentiation of cultural traits in societies and compares his
model with data from anthropological data derived from Murdock's
Ethnographic Atlas.

In the Forum section, Laurie Brown and Ann Harding review the work
using micro-simulation that they and colleagues have been doing in
Australia to contribute to the development of social security, welfare
and health policies.

Six recent books are reviewed in the Book Reviews section.
