The relationship between restrictions on premarital sex and the privacy of sexual practices is examined, using the degree of impenetrability of house materials as both a proxy and assumed cause for "offstage" or private sex. The author theorizes that permissive premarital sex norms are a response to open dwelling types which are themselves an adaptation to warm temperatures.

Udy divides methods of work organization into 'production determined', 'technologically determined', 'socially determined', and 'pluralistic' types, and examines their prevalence across societies with varying subsistence activities and levels of social and political stratification. Special attention is paid to processes of integration and differentiation and their role in effecting transitions between organization types.

This study tests an adaptational theory of military organization. Test of the relationship between population, residence type and military organization are presented; findings support the hypotheses.

Using a sample of 80 countries and political regions, the present study examines the effect parasite stress has on people's trust towards ingroup and outgroup members. The findings do not offer support of there being a concave relationship between parasite stress and ingroup member trust. The results do indicate that there is a U-correlation between trusting outgroup members and parasite stress.

This article employs logistic regression to test the relationship between house floor area and marital residence. Results indicate there is an association, but the relationship is stronger in a solely agricultural sample and nonexistent in a non-agricultural sample. This is likely due to the tendency for mobile groups to build several smaller homes for faster and more efficient household construction. Overall the authors suggest that floor area alone should not be taken as a sole indicator of marital residence.

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

This study investigates theories of male initiation ceremonies. The author examines a hypothesis related to child-rearing variables (sleeping arrangements and post-partum taboo) and rejects it based on empirical analysis. An alternative hypothesis related to male solidarity is offered.

The article investigates whether more socially restrictive societies provide more outlets for aggression. These authors operationalized restrictiveness with the presence of sorcery and unilineal kinship structure; the two outlets for aggression examined were occurrence of warfare and games of physical skill. Results suggest an association between these variables, though unilineal kinship structure was the better predictor of the existence of warfare.

The purpose of this book is to introduce a conceptual and methodological perspective called the "universalist approach," and to use this approach in exploring the pancultural antecedents and affects of parental acceptance-rejection of children,

This study uses macroecological approaches to test the impact of climate, social environment, inter-group borrowing and cultural history on vernacular house architecture among 1140 societies. The authors suggest that certain features will be influenced: wall materials, ground plan, roof shape, and floor placement. They use mixed binary and multinominal regressions models to test these predictions. The results strongly support that climatic drivers, cultural continuity, and inter-group borrowing predict three out of the four features: wall materials, roof shape, and floor placement. Social drivers are a strong predictor of every feature tested.
