Dynamical Structure of a Traditional Amazonian Social Network
Abstract
:Se hacía chicha, después se juntaba la gente y después todita la gente estaba borracha y cantaban las canciones de los animales: del chancho de tropa, del marimono, del maneche, y seguían cantando... Chicha was made, and the people got together, and then everyone was drunk and singing the songs of the animals—the white-lipped peccary, the spider monkey, the howler monkey—and on they sang...–Felipe Huallata [1]

- If it were the case that family i hosting family j on a particular day made it more difficult to host another family k on the same day (e.g., due to limited space or chicha), then an alternative specification of Equation (1), such as the multinomial logistic, might be preferred in order to represent the negative interdependence of the two dyadic interactions. However, since two or more families (up to a maximum of 10) were hosted on 106 out of 193 risk days that one family hosted at least one other family, the multinomial specification—which forces an either-or choice between families to host—would be inappropriate to apply to the current dataset. We thank one of the reviewers for these insights.

- The frequencies of hosting and attendance are also associated with household distance from village center (β = -0.816, p = 0.239 for hosts; β = -1.003, p = 0.001 for guests) and mean relatedness to other families in the community (i.e., node strength in the kinship network; β = 29.58, p = 0.119 for hosts; β = 23.75, p < 0.001 for guests); these relationships, however, are more directly captured (and statistically obviated: p > 0.6) by the dyad-specfic distance and relatedness terms.
