This article examines the conditions under which slavery occurs in preindustrial societies. Results suggest that social stratification and the existence of open resources are both necessary conditions for the occurrence of slavery.

In this study, the authors draw from intensity theory and combine previous research from the fields of behavioral ecology, economics, and social evolution to analyze drivers in the emergence and persistence of inequality across the world. They propose that environmental heterogeneity and circumscription (the difficulty of moving and establishing oneself in a new environment relative to remaining in the current one) play a significant role in the stratification of societies. Their results indicate that situations arise from various environmental conditions and levels of circumscription that may result in an individual giving up autonomy for material gain, thus favoring inequality.

This study examines organizational characteristics associated with administrative rationality, as well as how organizational development differs under varying social or cultural conditions.

The author attempts to test the "Oedipus-complex" hypothesis--the psychoanalytic idea that under certain conditions (such as the long-post partum sex taboo) males are sexually attracted to their mothers and as a consequence certain fears and anxiety are generaated. The hypothesis is tested at the societal-level using ethnographic data.

This book chapter tests new and pre-existing theories (Horton, Field, Bacon et al.) for the cause of variation in drinking across cultures. Folktale content is used to test psychological variables more directly than has been done previously. Folktale content is analyzed programmatically with an acknowledged error level of up to one-third. Results lend support to Field's 1962 theory that loose social organization facilitates drinking.

This article posits that nuclear, independent families are more common under certain economic conditions that affect food supply, demand for family labor, physical mobility, and property system. Empirical analysis suggests that nuclear, independent families are associated with hunting and gathering subsistence type and low social stratification.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.
