This article uses pre-defined criteria to sample 22 archaeological climate-related disasters from 9 distinct regions from eHRAF Archaeology. It quantitatively tests four hypotheses regarding change in conflict following climate-related disasters using multiple regression analyses and backwards stepwise regression. Findings demonstrate association between political strategy/authority decision making and degree of post climate disaster conflict.

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.

An extension of the author's 1993 study, An Archaeological Correlate of War, this study examines the relationship between community permeability and war in the ethnographic record using Naroll's study on household and population as a model with the aim of making inferences to the archaeological record.

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.

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.

Using the ethnographic record, this study develops and tests the idea that community permeability may be used as an archaeological predictor of warfare. With the exception of pastoral societies, community permeability predicts warfare.

The present study tests the theory that intrasexual selection or male attraction may explain variation in male aggression in a sample of 78 societies. Measures of intrasexual selection include: male subsistence, male war mortality, polygyny, sex ratio, and wives variance. The authors claim support for the theory.
