This article examines predictors of intimacy between husbands and wives. Emphasis is on equality of spouses. A causal model is presented.

This study investigates correlates of the post-partum sex taboo. Empirical analysis identifies several predictors, from extensive agriculture to localized kin groups. The authors suggest that the taboo imposes a burden on women and unmarried or monogamous young men, and it is best maintained in a community in which elders are in firm control and married women are considered outsiders due to village exogamy.

Controlling for community type, the researchers examine a potential relationship between family size (nuclear vs. extended) and communal leadership (hereditary vs. elected) in an effort to suggest potential predictors of hierarchical structures in societies. They claim support for their hypothesis that societies with nuclear families will be more likely to have democratic communal leadership, across four different community types.

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 seeks to examine the distribution and frequency of bride-theft. Tylor's (1889) findings between various forms of marriage by capture and certain other social instituions are confirmed.

This study analyzes the relationship between communal democracy and family size. Results show a weakly significant negative correlation between communal leadership and family size. Authors suggest that this relationship could be challenged based on the known curvilinear relationship between family size and cultural complexity. However, several further tests suggest that there are grounds for maintaining that family size has some independent influence on the existence of communial democracy.

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.

This article uses factor analysis to identify the key variables underlying the many cross-cultural associations reported by Textor (1967). Twelve factors are identified.

Researchers examine marriage patterns of 186 societies from the Standard Cross-Cultural Sample (SCCS). The eleven predictor variables are pathogen stress, arranged female marriages, population density, father roles during infancy, temperature, social stratification, wealth inequality, internal warfare, assault frequency, female agricultural contribution, and sex ratio. The two outcome variables measuring polygyny are cultural rules constraining polygyny and the percentage of married men who are polygynous. Controlling on phylogeny using a global supertree of the languages, analysis of marriage patterns reveals that assault frequency and pathogen stress are the strongest predictors of polygyny. These findings offer additional support for the theories of harem-defense polygyny and male genetic quality.

Based on work by Rosenblatt (1966), this article tests a hypothesis relating sexual freedom to romantic love. Findings suggest a relationship between premarital and extramarital sexual permissiveness equality for women and men and romantic love.
