This article re-examines societies that have been reported to be free of rape and asserts that the previous claims about societies are questionable. These findings are inconsistent with the hypothesis that rape is a learned behavior and offer support for the view that rape is a cultural universal.

This paper investigates two theories of social stratification: Lenski’s ecological-evolutionary taxonomy which is based on subsistence technology and Service’s taxonomy which is based on social organization. Findings indicate that different components of stratification are better explained by Lenski’s taxonomy, but a global concept of stratification matched better with the Service taxonomy.

Researcher's examine the presence of pubic hair removal (PHR) and retention in a cross-cultural setting, looking to see if such practices exist outside of the West, where it is well documented. Data from societies with PHR or retention from the eHRAF World Cultures sample were analyzed. Results indicate that PHR or retention exists cross-culturally without influence from the West. Commonly practiced for hygiene, women remove or retain pubic hair more often than men, with the main methods for removal being plucking.

Building on previous research concerning murder and suicide, this study investigates 18 forms of aggression and explores how they might be engendered by certain child-training practices. Results show a weak connection between most forms of aggression and child-training practices, but non-literate societies do show a positive correlation between murder and suicide. The author develops a theory positing that experience of social blockage will be related to outwardly-directed aggression, whereas social loss will be related to inwardly-directed aggression.

This paper tests assumptions regarding the inverse relationship between murder and suicide. Analysis suggests that murder and suicide in fact vary together, and they are also positively associated with overall punishment in a society.

This study explores predictors of variation in two dimensions of marital residence patterns among hunter-gatherers: 1) the tendency toward patrilocality versus matrilocality and 2) the tendency toward unilocality versus bilocality.

The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

This study relates the type of games present in a society to the level of cultural complexity. Authors use a "game-type combination scale" that categorizes societies as having: 1) games of physical skill only; 2) games of physical skill and games of chance; and 3) games of physical skill, games of chance, and games of strategy. Results show a relationship between the game-type combination scale and indicators of cultural complexity.

This article considers the consequences of modernization. Factor analysis is used to identify four stages of modernization: 1) changes in education, government, and trade; 2) changes in health, technology, and transportation; 3) changes in family, religion, and toilet; and 4) changes in behavior. The authors then consider five trends they expect to be associated with modernization and test whether they develop over the course of the four stages. Results indicate that these 5 trends—increased cultural complexity, female status, pacification, suicide, and social stress—are associated with only the first and fourth stages.

This article investigates a cultural patterning of altered states of consciousness. The authors use an ordinal variable for a society's trance type; its four levels are 1) trance, 2) trance and possession trance, 3) possession trance, and 4) neither type. Results suggest that trance type is associated with measures of societal complexity and subsistence economy. Regional differences and the effects of diffusion are also examined.
