This article focuses on the relationship between geographical location and sexual restrictiveness, proposing that less-constrained geographical areas have a higher risk of STDs and thus have higher sexual restrictiveness. The authors draw on data from Broude (1980) and other research to support this theory.

This paper "reduces Murdock's 210 categories to 30 variables, and intercorrelates and factor analyzes the variables for six world subdivisions as well as for the entire world." This article also discusses factor analysis as a method and examines the correlations more closely between the two regions that differed the most, North America and the Circum-Mediterranean.

The purpose of this paper is to examine female puberty rites and to suggest that such rites may be explained in terms of female physiology, as symbolized, for example, by menstruation.

The authors put forward a theoretical model called "personality integration of culture." At the heart of the model is the idea that psychological processes may help explain why certain aspects of culture are related to other aspects. To test this model they focus on theories and therapies regarding illness and they use psychoanalytic ideas on positive and negative fixation to suggest how differences in child-rearing customs may account for different ideas about the causes of illness. The strongest results relate to socialization anxiety in a particular area of socialization (e.g., oral, dependency, and aggression) amd respective causes of illness. Results regarding negative fixation are generally supported, whereas positive fixation is not.

This study tests an ecological-economic theory of female contribution to subsistence, focusing on subsistence type as a potential correlate. In an exploratory analysis, 28 independent variables (not all listed below) are examined. The relationship between female contribution to subsistence and female status is also examined.

This article investigates commonly accepted theories that purport to explain political centralization and investigate their relevance to sub-Saharan Africa. The leading ideas for the formation of political centralization using a worldwide sample include population density, inter-state warfare, and trade. However, the authors reported these factors are not predictive of the sub-Saharan Africa sample. The authors suggest that the lack of agricultural productivity in sub-Saharan Africa may have stunted population density therefore inhibiting political centralization and that Africa’s poor economic performance is, in part, due to lack of political centralization.

This study employs optimal scaling analysis to examine change in subsistence economy in a cross-cultural sample of 73 societies. Findings are discussed in addition to methodological considerations for sampling.

This study demonstrates a correlation in Australian Aborigines between clothing and climate. Using an ethnohistorical approach, the author tests hypotheses that indicate the use of clothing as a behavioral response to environmental factors.

This article tests four hypotheses regarding scarification, which is described as 1) a rite of passage, 2) a hardening/trauma procedure, 3) a nonadaptive sexually selected character, or 4) an adaptive pathogen driven sexually selected character. Only the third hypothesis is supported in a worldwide sample, suggesting that scarification is associated with polygyny. The other three are each supported in different regional subsamples—principally the first hypothesis (supported in Africa, the Insular Pacific, and South America).

The author investigates the associations between production relations, the character of productive forces, and sexual life. A significant correlation was found between production relations and the character of productive forces. Results also showed that more sexual freedom is associated with higher level of development of productive forces and an absence of internal oppression.
