  1. When controlling for pathogen stress and male mortality in war, the absence of the plow will be positively associated with nonsororal polygynyEmber, Melvin - Comparing explanations of polygyny, 2007 - 2 Variables

    This article uses logistic regression analysis to examine pathogen stress and male mortality in warfare as predictors of nonsororal polygyny. Differences between state and non-state societies are observed. The authors also retest variables from White and Burton's 1988 study on causes of polygyny, finding only fraternal interest groups and absence of plow significant.

  4. Controlling on age at marriage, the presence/absence of male mortality in warfare will be associated with polygyny (13).Ember, Melvin - Alternative predictors of polygyny, 1984 - 3 Variables

    "This paper describes how the "sex-ratio" explanation of polygyny compares with some alternative, supposedly causal explanations. The results suggest that polygyny is best predicted by two statistically independent factors--high male mortality in warfare…and delayed age of marriage for men."

  6. "A high male mortality in warfare is strongly associated with polygyny" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 2 Variables

    This paper suggests that polygyny may be best explained by uneven sex ratios, particularly an excess of women while men are engaged in warfare. The author also considers Whiting’s 1964 theory that used post-partum sex taboos to explain polygyny. These two theories are tested cross-culturally and results suggest that polygyny is a response to an unbalanced sex ratio in favor of women.

  7. In a multiple regression, father-infant sleeping distance will be associated with warfare frequency, marrying enemies, and polygyny (108).Ember, Carol R. - War and socialization of children: comparing two evolutionary models, 2007 - 4 Variables

    This article presents two evolutionary models that may explain relationships between war and socialization of children: the "environmentally contingent reproductive strategy" (ECRS) model put forward by Draper and Harpending (1982), and a model put forward by Carol and Melvin Ember. Results do not provide support for the hypotheses involving father-infant sleeping proximity derived from the ECRS model. The authors also find some inconsistencies with their own model.

  8. Resource scarcity will be positively associated with the committing of atrocities during warfare (37).Ember, Carol R. - Risk, uncertainty, and violence in eastern Africa: a regional comparison, 2012 - 2 Variables

    This article examines resource problems and warfare in a sample of societies from eastern Africa. The frequency and predictability of resource problems are examined, as are two other dimensions of warfare: resource-taking and commission of atrocities. Differences between state and nonstate societies, as well as pacified and non-pacified societies, are also examined and shown to affect associations between resource and warfare variables.

  9. Societies where there is at least a seven-year discrepancy in age at marriage or high male mortality in warfare will tend to have polygyny (13).Ember, Melvin - Alternative predictors of polygyny, 1984 - 3 Variables

    "This paper describes how the "sex-ratio" explanation of polygyny compares with some alternative, supposedly causal explanations. The results suggest that polygyny is best predicted by two statistically independent factors--high male mortality in warfare…and delayed age of marriage for men."

  10. Controlling for mistrust in a multiple regression analysis, natural disasters are positively associated with overall warfare (254)Ember, Carol R. - Resource Unpredictability, mistrust, and war: a cross-cultural study, 1992 - 3 Variables

    The article tests theories that may explain why warfare frequency varies from society to society. The focus is on ecological problems, particularly different kinds of resource scarcity, but social and psychological theories are also tested with both bivariate and multivariate analyses. Because unpredictable disasters are such a strong predictor in nonstate societies, the authors theorize that war may mostly be caused by a fear of nature.
