One clear trend that can be discerned in the last 15 years of otherwise-rather-protean Southwestern archaeology is a growing recognition that at any given time, demographic productive, and organizational strategies can be quite variable, even within comparatively small regions; that these...

The object of the workshop was to discuss and demonstrate the modeling of artificial societies and to suggest its potential for extending our knowledge about the prehistoric Southwest. Our efforts are part of the much larger questions anthropologists have asked for generations concerning how...

Reciprocity is an ancient and important social practice that evolved in very small-scale societies. In this paper we present an abstract model of the way systems work that are organized through balanced reciprocity (Sahlins 1972:185-275). This model will help us understand the general nature of...

The collapse of ancient societies such as the Mesa Verde-region pre-Hispanic Pueblos has puzzled generations of scientists. Many explanations for particular cases have been suggested, from combinations of social, political and economic factors (Tainter 1988), to climatic factors such as drought....

Recent developments in the study of the pehistory of the northern Mogollon and Anasazi areas of the North American Southwest are reviewed, with emphasis on the pre-A.D. 1150 period, in an attempt to identify key empirical results and incipient interpretive directions.

We present an agent-based model for voluntaristic processes allowing the emergence of leadership in small-scale societies, parameterized to apply to Pueblo societies of the northern US Southwest between AD 600 and 1300. We embed an evolutionary public-goods game in a spatial simulation of...

We introduce a model for agent specialization in small-scale human societies that incorporates planning based on social influence and economic state. Agents allocate their time among available tasks based on exchange, demand, competition from other agents, family needs, and previous experiences....

In an electoral framework of unidimensional two-candidate spatial competition with probabilistic voting, special interest groups present candidates with schedules that give the level of campaign contribution they will make for each feasible candidate policy location. Candidates, motivated by the...

A large body of literature documents that returns from currency speculation are highly volatile and possess a predictable component, which is itself highly volatile and serially correlated. Explaining the returns from currency speculation through the presence of a risk premium has proven...

Self-organizing maps (SOM) are unsupervised, competitive neural networks used to project high-dimensional data onto a low-dimensial space. In this article we show how SOM can be sued to draw graphs in the plane. The SOM-based approach to graph drawing, which belongs to the general class of...
