This study focuses on the labor activities of pregnant and postpartum women. Findings suggest that in most societies, the workload of women is lightened during and after pregnancy.

This study argues that different types of homosexuality must be examined separately. Authors focus on mentorship and pathic homosexual behavior and test factors that are associated with these two types of behavior.

This study investigates correlates of the post-partum sex taboo. Empirical analysis identifies several predictors, from extensive agriculture to localized kin groups. The authors suggest that the taboo imposes a burden on women and unmarried or monogamous young men, and it is best maintained in a community in which elders are in firm control and married women are considered outsiders due to village exogamy.

This paper presents tests of the relationships between tropical African agriculture and cultural variables regulating reproduction in order to examine a theory which suggests that the lagging or absence of tropical Africa's demographic transition is the result of pervasive 'pro-natal' cultural practices. Strength of association between these factors and non-plow agriculture, the traditional method of farming in tropical Africa, leads the authors to suggest that women's larger subsistence role in these societies favors extended family households in which child-rearing responsibilities can be shared, and polygynous marriage systems in which co-wives can contribute substantially to the family's labor productivity. These, along with erosion of regulations on postpartum sex and birth spacing which were prevalent prior to modernization, are identified as characterstics which have and will continue to resist fertility decline.
