  1. The infant/child's age at the cessation of breastfeeding is lower in preindustrial populations with agricultural or pastoral subsistence type than in hunting and gathering socieities (p. 50).Sellen, Daniel W. - Relationships between subsistence and age at weaning in "preindustrial" soci..., 2001 - 2 Variables

    This study tests the weaning food availability hypothesis, that both the introduction of foods other than breastmilk and the cessation of breastfeeding will vary by society's subsistence type. This hypothesis has implications for demography, as accelerated weaning can lead to increases in both mothers' fertility (due to decreased birth intervals) and infant mortality (due to the presence of pathogens in new foods).

  2. The infant/child's age at introduction of liquid and solid non-breastmilk foods tends to be lower in preindustrial populations with agricultural or pastoral subsistence types than in hunting and gathering socieities (p. 50).Sellen, Daniel W. - Relationships between subsistence and age at weaning in "preindustrial" soci..., 2001 - 2 Variables

  3. In societies with a more labor-intensive subsistence system, drug foods will function as labor enhancers (719).Jankowiak, William - Using drug foods to capture and enhance labor performance: a cross-cultural ..., 1996 - 2 Variables

    This study examines the relationship between drug foods and colonialism in relation to labor and trade. Relationships were found between political complexity, subsistence type, and the use of drug foods as labor and trade enhancers and inducers.

  4. Men's control of terrestrial game will be positively associated with a greater likelihood of high polygyny prevalence.Sellen, Daniel W. - Extracted-Food Resource-Defense Polygyny in Native Western North American So..., 2004 - 2 Variables

    In this article, the authors seek to understand the connection between male resource-holding potential and male mating success. This connection has been suggested by behavioral ecologists as a way of explaining differing rates of polygyny across cultures. The authors investigate this relationship by testing the relationship between rates of polygyny and male control of local subsistence sites among North American societies during the period of contact. They find a positive relationship between these two variables for both terrestrial and aquatic game, but not for gathered plants. This suggests support for the theory.

  7. Economic-technological variables will be positively related to game complexity (288).Ball, Donald W. - The scaling of gaming: skill, strategy, and chance, 1972 - 2 Variables

    This study analyzes the relationship between game complexity and sociocultural complexity. Significant relationships were found between several aspects of complexity and game complexity.

  8. Hunter-gatherers will experience more famine than those with other modes of subsistence (1).Berbesque, J. Colette - Hunter-gatherers have less famine than agriculturalists, 2014 - 2 Variables

    This study tests the common belief that hunter-gatherers suffer more famine than other subsistence types. Controlling for habitat quality, authors examine the relationship between famine and subsistence type and find that hunter-gatherers actually experience significantly less famine than other subsistence types.

  9. The relationship between subsistence technology and child training is affected by the type of enviornment in which a society is located (233).Welch, Michael R. - Environmental vs. technological effects on childhood socialization processes..., 1980 - 4 Variables

    The author expands on the findings of Barry, Bacon, and Child (1959), hypothesizing that type of environment is an intervening variable in the relationship between subsistence type and child training. A multiple classification analysis is used.

  10. A culturally independent association exists between dependence on agriculture and fertility(879).Sellen, Daniel W. - Fertility and mode of subsistence: a phylogenetic analysis, 1997 - 2 Variables

    This study tests for a relationship between subsistence type and fertility using phylogenetic and statistical analyses. The authors find a clear relationship between dependence on agriculture and fertility among non-permanently settled groups.
