This study examined the relationship between market integration and generalized prosocial behavior. The authors review theory suggesting that market integration fosters cooperation and fairness in dealing with strangers, and they investigate whether child training for generosity, honesty, and trust are associated with level of market integration among societies in the Standard Cross-Cultural Sample. Results do not indicate an association.

In this article, the authors seek to reevaluate Nolan's (2003) study on the primary determinants of war. They reanalyze his hypotheses with what they claim are more robust measures and methodology. They conclude that there is only a little evidence supporting Nolan's theories, that more productive echnology and higher population density predict war, and that overall ecological-evolutionary and sociopolitical explanations of war are equally supported by empirical data.

This article examines the relationship between child training and supernatural beliefs. The authors develop a schema delineating the role of the supernatural in nurturance and punishment; ten hypotheses associating the role of the supernatural with various child training practices are tested. Several are confirmed.

This study uses empirical analysis to parse out different dimensions of permissiveness in child-rearing. Oral-sexuality, independence-anality, and aggression are the dimensions identified.

The complex set of beliefs and practices in which the cult of the guardian spirit consisted is examined.

This article explores determinants of non-classical polyandry, which the authors assert is more common than is usually conveyed. Results indicate that societies with non-classical polyandry tend to be small scale and egalitarian, practice hunting and gathering or horticulture, and have a male-skewed sex ratio. Overall polyandry is thought to add to the reproductive fitness of both men and women.

This paper investigates correlations between social structure and the pattern of kindship nomenclature. Results suggest that lineage nomenclatures are associated with several aspects of social structure, including unilineal descent, the domestication of plants and animals and inheritance.

This study challenges an earlier paper's claim that matrilocal residence predicts the development of girls' puberty rites. The author suggests that girls' puberty rites may in fact predate matrilocality in some locations.

This article explores biological, psychological, and social explanations for menstrual taboos. Attention is paid to the role of men in rituals associated with reproduction--i.e. before, during and after childbirth, as well as during girls' puberty rites.

This article explores narcissism and child-rearing. The author presents a theory that, if a society’s structural pattern weakens the marital bond, the mother will be ambivalent toward the son who consequently will become narcissistic. This process would reinforce itself as it is repeated by each generation.
