This study examines whether theories of illness causation are regionally distributed, as was reported by Murdock (1980). Optimal scaling analysis suggests two regional patterns, one in African and Circum-Mediterranean societies, the other in Eurasian, Insular Pacific, North American, and South American societies.

This study first reviews two explanations of menstrual taboos: taboos as an aspect of social rigidity and a psychogenic interpretation of menstrual taboos. The authors chiefly advocate a sociogenic explanation of menstrual taboos.

This study tests for a relationship between subsistence type and fertility using phylogenetic and statistical analyses. The authors find a clear relationship between dependence on agriculture and fertility among non-permanently settled groups.

This study is based on data given in Quincy Wright's (1942) 'A Study of War.' The author examines many correlates of belligerence in non-industrial societies. Results suggest that political organization, inter-cultural relations, and level of primitivity are associated with belligerence.

This paper examines patterns of cultural learning in pastoralist societies and compares them to those found in hunter-gatherer societies. The study analyzed 198 texts from 13 pastoralist cultures in the eHRAF World Cultures database and found that most cultural skills and knowledge were acquired in early childhood, with parents and non-parental adults as the primary sources of transmission. Teaching was the most common form of learning across all age groups, with minimal variation in transmission between different age groups. While similarities were found between the cultural learning patterns of pastoralists and hunter-gatherers, pastoralists were less likely to mention learning from peers and more likely to mention learning via local enhancement and stimulus enhancement. The importance of teaching did not increase with age in pastoralist societies, unlike in hunter-gatherer societies.

This study suggests that animals' avoidance of human menstrual odor could be a factor affecting menstrual taboos in societies that depend on hunting. Results indicate a significant, positive relationship between dependence on hunting and menstrual taboos.

This study examines the status and treatment of the elderly in non-industrial societies. Associations are found between social complexity, subsistence type, and the status and treatment of the elderly.
