In the present study, Peregrine tests two perspectives regarding social resilience to climate-related disasters: 1) that societies with more inclusive and participatory political structures (corporate political strategies) are more resilient to climate-related disasters, and 2) that societies with tighter adherence to social norms are more resilient to climate-related disasters. Results support the notion that societies with greater political participation are more socially resilient to catastrophic climate-related disasters. Because these results are justifiably generalizable across multiple historical and cultural contexts, Peregrine's findings are a useful contribution to aid in disaster response policy decision making.

The present study investigates whether there is resilience variability following climate-related disasters in societies that are corporate-oriented, which promote participatory and inclusive structures, and exclusionary-oriented, which limit political authority and power. The findings offer modest support for social resilience theory that more flexible (i.e. more participatory) societies would be more resilient after a disaster than less flexible societies. Although only 5 of 14 correlations are significant, the direction is significant by a binomial sign test.

The present study attempts to replicate the Ember, Ember, and Russett (1992) worldwide finding that fighting rarely occurs between democracies in a sample of eastern African societies. Following the earlier study, the authors considered internal warfare to be an analog of international warfare and measures of political participation analogous to democracy. The researchers also explore if there is an association between political participation and committing atrocities. Contrary to past findings, internal warfare was not predicted by the same set of variables as the 1992 study, but there is an inverse relationship between committing atrocities and political participation. However, when additional variables were added, internal warfare was significantly predicted by less political participation.

The second and third parts of this book classify the economic systems of foraging and agricultural societies in the SCCS based on correlations between their institutions of property an distribution. These economic types are then examined for relationships with other social, political, demographic, and environmental factors in order to draw tentative conclusions regarding the origins of the Agricultural and Industrial Revolutions. The fourth part of the book uses cross-national data to examine similar associations in industrial/service economies, and is not included here.

The author analyzes conditions that might favor social resilience during the Late Antique Little Ice Age (ca. 536-556 CE). The assumption is made that climatic conditions in the Northern Hemisphere during this period of time are very similar to those that would occur during a nuclear winter. These conditions include a drop in temperature and decreased solar radiation from volcanic eruptions. Measures for social resilience come from multiple variables for social change, which are tested against measures for type of political engagement. It is argued that broad political participation is correlated with resilience.

This paper reviews the results of the author's cross-cultural studies of war and aggression and their implications for prehistory.

Using a self selected sample of 33 ex British colonies and the Ethnic Power Relations database, the author sampled 170 ethnic groups from Africa, Asia, and the Middle East to test for association between precolonial state formation, colonial state building tactics, and modern ethnic conflicts. The author theorized that ethnic groups that were centrally governed before the colonial period were less likely to be recruited to colonial security forces, leaving them out of the picture during the formation of the independence movement and the formation of a post-colonial regime. This in turn is theorized to lead to greater contemporary armed conflict against the regime from which they were excluded.

This article tests the effects of variables associated with political participation on the frequency of internal warfare. Findings suggest support for the hypothesis that democracies rarely fight each other.

This article suggests a general theory of conflict and violence that may help explain the conditions under which internal conflict co-occur or are differentiated.

This article explores the factors that predict rituals of conflict. Hypotheses are derived from Gluckman's analysis of Southeast African rituals of rebellion and are tested against a cross-cultural sample.
