Based on prior findings, the present study tests the theory that subsistence type, specifically agricultural level, influences descent type, conjugal formation, and marriage type. All three of the latter variables are predicted to be antecedents of ancestor worship. The author claims support for the theory.

This study takes an economic approach in examining the practice of human sacrifice as it relates to notions of the economic value of human life. Codes are included.

This article suggests that the relationship of monogamy and independent families to societal complexity is best represented by a curvilinear rather than a linear model. Though the variance explained in this relationship is low, it is somewhat increased when variables are scored as dummy variables rather than ordinal.

This study examines why conflict emerges and how societies resolve it. The authors posit that increasing societal scale and differentiation create more potential for conflict but also more complex forms of conflict resolution. Analysis supports this theory, showing that measures of cultural complexity are positively associated with legal mechanisms for conflict resolution.

This article provides a descriptive account of the prevalence and variation in out-of-body experiences (OOBEs) worldwide. The author suggests that contemporary social science explanations for OOBEs (i.e. social control, crisis, and dream theories) are inadequate. Certain beliefs regarding OOBEs, such as whether they occur and the conditions for their occurrence, were shown to be relatively similar cross-culturally.

This study tests various theories on conflict. Multiple regression analyses are presented and support is given for the psychocultural perspective.

This paper explores societal-level mechanisms associated with women’s participation in and exclusion from political life. Analysis suggests there are two statistically independent types of female political participation: involvement in decision-making and the existence of positions controlled by or reserved for women. Multiple regression analysis identifies several social-structural, psychocultural, and behavioral correlates for both types of female political participation and explanatory theory is discussed.

The author examines modes of marriage and societal organization from a functionalist (general evolutionary) perspective. He focuses on the relationships of subsistence (economic) patterns, settlement patterns, and social complexity to predicting modes of marriage, with particular emphasis on the importance of subsistence as an underlying structural influence upon social patterns.

The author evaluates predictions from the standard model of intensification of food production and suggests it be rejected based on an analysis of 40 societies. The standard model proposes that food producers will increase their energy input until the maximum possible output is achieved, at which point output and labor productivity will fall and producers will invent or adopt new technologies. He then proposes a different model, which he terms the cultural niche construction model. The cultural niche construction model proposes that societies will minimize their energy input while maximizing their returns through continual technological adaptation and niche construction. After predictions from this second model are tested, the author suggests tentatively accepting the cultural niche construction model as a new framework to explain transitions to complex societies.

"In an earlier study of the evolution of elements of legal organization, a Guttman scale was developed having as scale steps (elements of legal organization) counsel, police, and mediation. In this study, one further step, that of courts, is discussed, and a new Guttman scale for legal evolution presented."
