BACKGROUND Local migration in developing-world settings, particularly among rural populations, is an important yet understudied demographic process. Research on migration in such populations can help us test and inform anthropological and demographic theory. Furthermore, it can lead to a better understanding of modern population distributions and epidemiologic landscapes. OBJECTIVE The purpose ...

Though explicit pronouncements are difficult to find, the historical literature on the Middle East seems to be based on the assumption that the large desert areas contain societies and economic systems which are for the most part autonomous, but which occasionally impinge--sometimes with catastrophic results--on the lusher agricultural and urbanized areas. The deserts are designated by terms eq...

A growing body of theoretical and empirical research has examined cultural transmission and adaptive cultural behaviour at the individual, within-group level. However, relatively few studies have tried to examine proximate transmission or test ultimate adaptive hypotheses about behavioural or cultural diversity at a between-societies macro-level. In both the history of anthropology and in prese...

The papers in this issue are from a conference held in May 2002 at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. This conference brought together researchers from all current western gorilla sites for the first time with the aim of synthesizing the most current information available on western gorilla behavioral ecology. Our goal was to assess the degree of behavio...

Firms are increasingly selecting hybrid governance in interfirm relationships to execute a wide range of activities. To aid cumulative theory building, we propose a typology of hybrid governance identifying four types characterized by the levels of two types of asset specificity pertaining to intangible assets: process specificity and expertise specificity. We validate the typology this using d...
