This article examines the relationship between grammatical forms and a society’s economic activity, particularly whether property-based societies are more likely to develop the possessive verbs. Analysis supports an association.

The author explicitly defines and provides code for male and female age organizations and secret societies in Africa, as well as their significant sociopolitical roles within society. The author conducts preliminary analysis using the codes to explore characteristics and regional patterns of such organizations and societies. The analysis is compared to existing studies in order to assess the code and better understand cross-cultural patterns and variances. The author identifies the usefulness of the code beyond Africa, and discusses avenues for future research. No explicit hypotheses were tested, but Ericksen includes some descriptive generalizations.

This article examines cross-cultural variation in customary birth practices for men and women, testing a general hypothesis that birth practices represent tactics in negotiations over paternity. Data supports this hypothesis, and a series of related variables are tested in bivariate analysis and path analysis. Findings suggest that compensation demands at birth are associated with maternal restrictions from paternity-related agreements (e.g. maternal seclusion during birth), and fraternal interest groups are associated with the husband’s ritual involvement at birth (e.g. demonstration of the couvade).

Female genital mutilations within Africa are associated with strong fraternal interest groups, virginity tests, and conservative permarital sex norms. Codes and ratings for female genital mutilations, virginity tests, premarital sex norms, and female initiation rites are presented in this article.

Feuding and other responses to malfeasance are examined cross-culturally. The geographic distribution of responses are presented and odds ratios/logistic regression models are employed in analyzing the effect of socio-economic, historical and ecological variables on responses to malfeasance. Codes are included.

This article reviews aspects of cooperative breeding in humans and nonhumans. Life history characteristics, childcare helpers, and demographic implications of cooperative breeding are examined. Cross-cultural data is presented, though no empirical hypotheses are tested.

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.
