The author presents an approach to understanding initiation ceremonies that differs from the approach of Whiting (1962). Cohen looks at the association between legal and kinship systems and childrens' experiences growing up. Several significant association are found between these variables.

This study investigates political organization and the punishment of nonmarital sex. The author suggests that "the rules governing each type of nonmarital relationship are outgrowths of different relationships between controlling political bodies and local boundary systems."

This article examines the relationship between early food gratification, emotional predispositions to share food with others, and community systems. Results suggest that gratification of food needs varies with community type, and young children who receive food whenever they cry or ask are more likely to share food in adulthood. In broader terms, the need to receive from others is gratified differently under different sociological conditions, and these differences influence individuals toward divergent socially patterned behaviors in adulthood.

The author postulates that there are different types of friendship that characterize different societies--"inalienable friendship," "close friendship," "casual friendship," and "expedient friendship." These types are postulated to be characteristic of different types of community systems (described on pages 314-318 of this volume).

The theoretical concern of this work is with different types of liability that societies emphasize in their legal systems and how that plays out in understanding the transition from childhood to adolescence as well as variation in incest taboos.

Using a psychoanalytic-materialist approach, the author examines the possible effects of environmental unpredictability on the prevalence of unprovoked aggression by characters in folktales.

This study tests the relationship between group morality and hostility towards outgroups. Cross-cultural findings support the hypothesis that ingroup loyalty is associated with a greater emphasis on outgroup violence. Results from a second psychological study are included and also support the hypothesis.

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 article uses the Standard Cross-Cultural Samples to test the relationship between disease and economic growth among sub-Saharan African societies. The authors suggest that a higher disease prevalence limits social integration and economic development since pre-colonial times. The variable measuring economic growth is the complexity of large or impressive structures. The hypotheses are that 1) pathogen stress is negatively correlated to the presence of complex buildings, and 2) pathogen stress is positively correlated to increased ethnic diversity. The results support both hypotheses, and there are additional results, like 1) the negative correlation between pathogen stress and current income per capita and 2) the negative correlation between the increased ethnic diversity and current income per capita. Overall, this article shows the robust relationship between disease and economic development.
