This article reassesses the question of relative peacefulness/violence of preindustrial societies. It tests two materialist theories suggesting that more advanced subsistence techniques and population pressure will increase the likelihood of warfare.

Using multiple logistic regression, the researchers compare the relative strength of predictors of land ownership across 102 societies. The analysis finds significant predictive power in factors such as neighbors' property system, population density, and geography.

This study employs a psychological theory and builds on the holocultural literature on male homosexuality. Two hypotheses relating homosexual behavior among men to social constructs for sexuality (the couvade, male transvestism) are derived from a study by Munroe (1980). The hypotheses are tested and supported in a sample of cultures drawn from Munroe's codes and the Human Relations Area Files.

This article examines the results of a study (Gaulin 1980) on male parental certainty and subsistence type. Methodological errors are assessed and the hypotheses are retested.

This study re-examines the hypotheses offered by Kleiman (1977) linking monogamy in humans to monogamy in other animals. Of seven hypotheses, only two were weakly supported when using a cross-cultural analysis.

This paper suggests that Fischer's (1961) "male security" variable is not adequate. Cross-cultural analyses suggest that male security in the realm of father-son interaction may be more important than male security in the realm of heterosexual interaction in explaining the line shape preference of a society.

This article re-examines Abernethy's (1974) hypothesis that female power within a marriage negatively affects male sexual functioning. Results do not support this hypothesis.

This article examines reasons for the variation in sexual foreplay practices cross-culturally. Results suggest that exclusive mother-child sleeping arrangements is significantly associated with the presence of foreplay.

This article explores the relationship between sexual dimorphism of stature and variables of marriage, diet, subsistence and environment. Significant associations were found between security and plentifulness of food supply, protein availability, and sexual dimorphism of stature.

This article presents a reanalysis of the theory put forth by Hartung (1981) regarding the relationship between inheritance and paternity confidence. The authors take issue with the original sample used and retest the hypothesis.
