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 posits a theory of social evolution based on agriculture. The author suggests that a society’s energy source, type of tool materials, and systems of agriculture constitute a variable cluster, and that they are associated with societal scale, economic differentiation, and mode of political integration. Empirical analysis supports this neoevolutionary theory of agriculture.

This study presents a sociological theory of marriage type based on socioeconomic organization. Results suggest that intensive agriculture, more stratification, greater political integration, a fixed settlement pattern, a larger population, and greater labor specialization tended to be correlates of monogamy.

This study uses a multiple regression analysis to examine the relationship between society type and several variables of societal organization. Results suggest that limited family type is more likely to be found in complex societies.

This article suggests that Spiro's (1965) study on typology of social structure used a biased cross-cultural sample and possibly obscured regional patterns in data. Hypotheses related to marital structure, descent rules, food production and social stratification are tested.

This chapter investigates correlates of competitive adolescent games, focusing on societal and family characteristics as well as socialization variables and personality traits. Data suggest that games meant to encourage competitiveness will be more common for boys than for girls. Competitive games are also statistically associated with low societal and technological complexity, small and monogamous family organization, less physical contact and comfort in infant socialization, less integration in adult activities, and various personality traits.

This paper presents research on the factors that promote romantic love as a basis for marriage in non-industrial societies. After a discussion of the previous literature on romantic love in ethnographic societies, the authors used the SCCS, EA, and data from eHRAF to create a data set of 109 cultures and then utilized multiple ordinal regression to test the relationship between different types of families and post-marital residence practices and the importance of romantic love in marriage. The findings show that monogamy is significantly correlated with romantic love, while nuclear family organization and neolocal post-marital residence are not significantly correlated. The presence of polygyny is found to lower the probability of romantic love being a basis for marriage. These findings contradict previous research, which found a relationship between non-neolocal post-marital residence and the presence of romantic love in marriage.

This article attempts to construct an empirically-based typology of social structure. Marital structure, government, food production, and stratification are among the factors considered.

The study examines the relationship between communal democracy and family size. The results indicate a weak significant negative correlation between communal leadership and family size. Even though the researchers suggest that the known curvilinear relationship between the variables could challenge this finding, further tests indicate that there are grounds for maintaining that family size has some independent influence on the existence of communal democracy.
