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.

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

This study examines the relationship between political participation and warfare, suggesting that checks on power, removal of leaders, extent of political participation, and absence of fission will be negatively associated with the frequency of warfare. This hypothesis was supported with empirical analysis.

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.

This article employs cross-national and cross-cultural methods to investigate whether pathogen stress is a direct determinant of authoritarianism. The study controls on other factors such as famine, warfare, and malnutrition and evaluates alternative causal models.

In an attempt to explain communal conflict, this study investigated how customary institutions (i.e. legislatures, courts, and chiefs) may impact the communal conflict activity of groups in Africa. The authors suggest that customary authorities act as local enforcements to mitigate within-group conflict, therefore a higher number of customary institutions should decrease communal conflict. Using data from 143 politically relevant ethnic groups, the authors showed support for their hypothesis and demonstrated marginal support that more inclusive customary institutions would be associated with less communal conflict.

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.
