SUMMARY:Sean Prall: Perceptions that matter: using peer evaluations and dyadic data to explore behavior in rural Namibia
DESCRIPTION:Dr. Sean Prall \nDept. of Anthropology\, University of Missouri \nhttps://sprall.github.io/ \nTitle: Perceptions that matter: using peer evaluations and dyadic data to explore behavior in rural Namibia \nAbstract: Reputation and social status are central to research on mating\, social learning\, and cooperation. However\, evolutionary social scientists face significant methodological difficulties in accurately measuring people’s perceptions of others. As a result\, most studies in anthropology and psychology rely on hypotheticals or experimental paradigms in lab-based settings. While this work has yielded insight into how people think about these domains\, these approaches are limited in their ecological validity\, ability to capture a dynamic and competitive social environment\, and may recapitulate social norms instead of yield novel information about social dynamics. An alternative approach\, which I will explore in this talk\, is the use of dyadic peer evaluations. Using two unique datasets\, each with more than 10\,000 ratings from a single community in Namibia\, I will explore two case studies: 1) mating market competition\, and 2) women’s status. I will highlight the benefits and potential drawbacks of dyadic peer evaluations and explore how these methods can be used as part of a larger toolkit to explore cultural and behavioral attributes of human populations. \nZoom: https://ucla.zoom.us/j/92826436236?pwd=SytQNTNPSWdwaDNlTm05d2srdXNHUT09 \nMeeting ID: 928 2643 6236 \nPasscode: BEC

SUMMARY:Tom Kraft: Modeling the dynamics of infectious disease transmission in a small-scale subsistence population
DESCRIPTION:Dr. Tom Kraft \nDept. of Anthropology\, University of Utah \nhttps://thomaskraft.weebly.com/ \nTitle: Modeling the dynamics of infectious disease transmission in a small-scale subsistence population \nAbstract:​​​\nInfectious disease dynamics are governed by patterns of contact that vary by geography\, social organization\, mobility\, network structure\, and cultural factors. Based on speculation about these parameters in contemporary subsistence populations\, voluntary collective isolation (VCI) has been proposed to mitigate the impact of global disease transmission into relatively isolated\, largely self-sufficient\, small-scale indigenous groups\, most recently with respect to the SARS-CoV-2 pandemic. To assess the vulnerability of small-scale populations to epidemics and the viability of VCI and other interventions\, I simulated disease transmission among Amazonian forager-horticulturalists (Tsimane) using a stochastic network metapopulation model parameterized with a wealth of high-resolution data on social behavior\, mobility\, and population structure. Findings indicate that relative isolation and Tsimane social organization offer little protection from disease introduction and widespread transmission\, even in the most remote communities\, and that VCI is unlikely to be effective under contemporary socioeconomic conditions. The occurrence of a local SARS-CoV-2 epidemic in this region in mid-2020 afforded an opportunity to test this model; comparison of model results to empirical outcomes measured using serological assays shows good model fit amidst very high rates of transmission. These results demonstrate the applied utility of anthropological data\, and suggest that VCI alone is unlikely to be a viable intervention strategy. Pandemic policies should instead aim to protect small-scale communities by delivering distributed health care resources across remote areas. \nZoom: https://ucla.zoom.us/j/92826436236?pwd=SytQNTNPSWdwaDNlTm05d2srdXNHUT09 \nMeeting ID: 928 2643 6236 \nPasscode: BEC
