This study re-examines Otterbein's (1970) data on territorial expansion and military sophistication. The author finds that a society's level of "ferocity (or tendency to attack) is more highly correlated with territorial expansion than military sophistication.

This paper tests "theories which suggest that there are causal-functional relationships between the dependent variables peacemaking and peace stability on the one hand and certain independent variables, such as political complexity, warrior class, warfare objectives, cultural homology and intersocietal ties, on the other hand." Significant relationships were found between the last three independent variables.

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 discusses the characteristics of adolescence cross-culturally and examines the differences in the adolescent experience for males and females. Several relationships are tested in order to gain an understanding of cross-cultural patterns in adolescence.

This article investigates commonly accepted theories that purport to explain political centralization and investigate their relevance to sub-Saharan Africa. The leading ideas for the formation of political centralization using a worldwide sample include population density, inter-state warfare, and trade. However, the authors reported these factors are not predictive of the sub-Saharan Africa sample. The authors suggest that the lack of agricultural productivity in sub-Saharan Africa may have stunted population density therefore inhibiting political centralization and that Africa’s poor economic performance is, in part, due to lack of political centralization.

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.

Theories about the relationship between warfare, militarism, male dominance and authoritarianism are tested.

"This paper presents an exploratory attempt to solve the problem of how to infer traits for which no direct material evidence remains." The author suggests that the archeologically defined community pattern can predict several sociocultural traits. Results support this hypothesis.

This study examines land ownership and territoriality among hunter-gatherers in relation to resource density and predictability and defense technology. A model is presented and briefly tested on a cross-cultural sample of 14 hunter-gatherer societies. Results suggest that societies in more resource-rich areas will be more territorial than societies in less resource-rich areas.

This book examines naming practices cross-culturally. The author posits that naming practices help to both reflect and create conceptions of personal identity. Several correlations between name meanings and practices and various sociocultural variables are presented.
