  1. 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."

  3. 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

  4. In a multiple regression including non-sororal polygyny and marrying enemies as predictors, pathogen stress will not be significantly related to father-infant sleeping distance (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.

  5. 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

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.

  6. "There is no significant association between a long postpartum taboo and polygyny in either the high or low male mortality situation . . . when we control for male mortality in warfare" (202)Ember, Melvin - Warfare, sex ratio and polygyny, 1974 - 3 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. Polygynous societies that engage in a long postpartum sexual taboo will be positively associated with male segregation at puberty when the factor of living-quarter arrangements is controlled (206)Kitahara, Michio - Polygyny: insufficient father-son contact and son's masculine identity, 1976 - 4 Variables

    The purpose of this article is to examine circumcision and segregation of males at puberty. It is suggested that when the son has insufficient contact with his father due to the separation caused by polygynous relationships, the son may develop a feminine personality. The significance of this is compared with the significance of a close mother-son relationship.

  8. More father-infant sleeping distance will be positively associated with resource unpredictability (107).Ember, Carol R. - War and socialization of children: comparing two evolutionary models, 2007 - 2 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.

  9. A short supply of women will be positively associated with the frequency of warfare--Divale and Harris (251)Ember, Carol R. - Resource Unpredictability, mistrust, and war: a cross-cultural study, 1992 - 2 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.

  10. In state societies, pathogen stress will be 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.
