It is suggested that the degree of political complexity is more strongly related to degree of social differentiation than to size and concentration of population.

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 article examines the relationship between warfare and trade and concludes that the relationship varies within different levels of political organization.

This study examines how social structure, political organization, and intersocietal relations may affect the incidence of internal warfare (between culturally similar political communities). Results show that in uncentralized political systems, fraternal interest groups and unauthorized raiding parties may increase the incidence of internal war.

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

This book takes a cross-cultural, cross-historical approach to the study of military deterrence. Political, economic, and geographic correlates are considered, particularly military and diplomatic strategy. Several hypotheses are tested and some are supported.

Using a sample of 145 African societies, the authors seek to examine the relationship between segmentary lineage organization and conflict. Presented is evidence supporting the claim that segmentary lineage societies are more prone to conflict and to conflicts larger in scale and duration. The authors aim to contribute to a better understanding of the determinants of conflict, and additionally address the applicability of the present study beyond Africa.

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 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.
