  1. Species with long infant dependencies will be negatively associated with breeding seasons (204).Ember, Carol R. - The evolution of human female sexuality: a cross-cultural perspective, 1984 - 2 Variables

    This paper suggests a tentative analysis of continuous female sexual receptivity based on a random sample of mammals and birds. It is suggested that humans developed continuous female sexual receptivity because humans have the unusual combination of long infant dependency, group living, and male-female bonding.

  2. 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.

  3. "Societies with greater resource scarcity will have more positive valuations of fatness in women" (258).Ember, Carol R. - Valuing thinness or fatness in women: reevaluating the effect of resource sc..., 2005 - 2 Variables

    This study focuses on preferences for thinness or fatness in women cross-culturally. Results contradict previous studies and the hypothesis that preference for fatness in women is predicted by resource scarcity. Alternative explanations for valuation of fatness are explored, including climate and male dominance.

  5. Beyond-household sharing will be more habitual in societies with greater resource stress.Ember, Carol R. - Our better nature: Does resource stress predict beyond-household sharing, 2018 - 5 Variables

    The present research investigates food sharing and labor sharing practices of 98 nonindustrial societies. The aims are to: 1) document the frequency and scope of sharing, and 2) test the theory that greater sharing is adaptive in societies subject to more resource stress (including natural hazards).

  8. Resource scarcity will be positively associated with warfare frequency in nonstate, nonpacified societies (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.

  10. Greater contact between mother and child is positively associated with men's fear of sex with women (660).Ember, Carol R. - Men's fear of sex with women, 1978 - 2 Variables

    This study examines ecological, social, and psychological theories for men's fear of heterosexual sex in a cross-cultural sample. Findings support the hypotheses and a causal model is presented.
