Building on previous explorations of grid/group analysis for cross-cultural research (Caulkins 1999), the researchers test for relationships between grid/group variables and measures of social capital among nine North American ethnic groups. The article contributes to a discussion of whether the primary source of economically productive social capital is the general ethnic group ("ethnicity as social capital" hypothesis) or the family unit ("family as social capital" hypothesis), using group, grid, and census data on self-employment as indicators. The authors conclude that their results are consistent with the "family as social capital" hypothesis.

Ackerman performs a cross-cultural analysis on the structural determinants of divorce rate as originally hypothesized by Max Gluckman and elaborated on by other researchers. Ackerman's results suggest that when spouses share a network of affiliation, divorce rates are low; when spouses maintain separate affiliations, divorce rates are high. Ackerman's statistical analysis and discussion provide an explanatory framework for further research.

Derived from the fear of supernatural punishment hypothesis, this paper explores whether the prosocial attitude of a group or individuals will increase with the threat of punishment from a high god or visible supernatural agent, such as sorcerers and witches. The author found that fear of supernatural punishment did not affect prosocial behavior and suggested that religious beliefs may give rise to institutions with the task of enforcing social compliance rather than direct control.

This paper examines the relationship of productive variation in land between ethnic groups to determine if an increased range of producible goods will increase trade, thus decreasing language diversity between neighboring groups. The author initially found that high-variation in land production lessened the diversity of language between ethnic groups in that area. To further test this correlation, the author found that high-productive variation increased trade and exogamous marriage and decreased inter-ethnic conflict. Based on these findings, the author suggests that neighboring ethnic languages co-evolved through the economic benefit of inter-ethnic trade and social interaction.

This book investigates individual and group responses to death and the problems that death can create in a society. Several hypotheses regarding grief and mourning, as well as their variation with other societal variables, are supported with cross-cultural tests.

Drawing from Social Darwinism theories, this article posits warfare (specifically, military success) as a selective mechanism in the evolution of culture. The hypothesis was not supported.

This study tests a common theory that predicts a positive relationship between exogamy and cross-allegiances between social units. Results did not support this prediction. Cross-allegiances were only weakly related to cross-cousin marriage.

This article explores the factors that predict rituals of conflict. Hypotheses are derived from Gluckman's analysis of Southeast African rituals of rebellion and are tested against a cross-cultural sample.
