Testosterone and paternal care in East African foragers and pastoralists.
The 'challenge hypothesis' posits that testosterone facilitates reproductive effort (investment in male-male competition and mate-seeking) at the expense of parenting effort (investment in offspring and mates). Multiple studies, primarily in North America, have shown that men in committed relationships, fathers, or both maintain lower levels of testosterone than unpaired men. Data from non-west...
متن کاملSocial Identity and Manipulative Interhousehold Transfers Among East African Pastoralists
We model interhousehold transfers between nomadic livestock herders as the statedependent consequence of individuals strategic interdependence resulting from the existence of multiple, opposing externalities. A public good security externality among individuals sharing a social (e.g., ethnic) identity in a potentially hostile environment creates incentives to band together. Self-interested int...
متن کاملLactase Persistence Alleles Reveal Partial East African Ancestry of Southern African Khoe Pastoralists
The ability to digest milk into adulthood, lactase persistence (LP), as well as specific genetic variants associated with LP, is heterogeneously distributed in global populations. These variants were most likely targets of selection when some populations converted from hunter-gatherer to pastoralist or farming lifestyles. Specific LP polymorphisms are associated with particular geographic regio...
متن کاملFood Aid Targeting, Shocks and Private Transfers Among East African Pastoralists
Public transfers of food aid are intended largely to support vulnerable populations in times of stress. We use high frequency panel data among Ethiopian and Kenyan pastoralists to test the efficacy of food aid targeting under three different targeting modalities, food aid’s responsiveness to different types of covariate shocks, and its relationship to private transfers. We find that, in this re...
متن کاملCross-Cultural Adaptability 1 Running Head: Cross-Cultural Adaptability Inventory Examining the Psychometric Properties of the Cross-Cultural Adaptability Inventory
The current study examined the factor structure of the Cross-Cultural Adaptability Inventory (CCAI) to better understand the psychometric properties of this instrument. Subsequent to the current study, the CCAI, which was developed to provide a selfinventory of an individual’s cultural adaptability, had limited study of its measurement characteristics. Therefore, the structure was examined usin...
