Wednesday Tea, School of Human Evolution and Social Change Conference Room, 254 2:30-3:30 p.m.

• Past talks:

• January 23: Kim Hill (SHESC) presented his discussion on "Exceptional cooperation in humans produced by obligate cooperative breeding and culture-mediated altruistic cooperation across unrelated individuals and social units."

• January 30: Marco Janssen (SHESC) discussed his work on population movement and aggregation in the pre-historical American Southwest. Using stylized agent-based models the diverse types of adaptation (sharing, storage, exchange, mobility) to the arid landscape with high temporal and spatial variability is explored.

• February 6: Tomimi Tanaka (Global Studies) discussed experiments in Vietnamese village communities to investigate how social status, exemplified by ethnicity, affects preferences for distributions of income (including third-party enforcement of distributional norms) and economic cooperativeness.

• February 13: Amber Wutich (SHESC) presented her talk on emotional distress over water insecurity.

• February 20: Marty Anderies (SHESC) presented his talk on robust control and the governance of social-ecological systems.

• February 27: Nicholas Radtke (Computer Science): What makes open source projects successful?

• March 5: Robert Tobias (SHESC) gave his presentation on Psychology the engineering way: Modeling processes of behavior change for improving campaigns.

• March 12: Wander Jager (Groningen University, the Netherlands) Simulating opinion dynamics. Multi agent based simulation is a popular technique in studying opinion dynamics because it allows studying how interactions between individual agents may result in phenomena at the population level, such as polarization, convergence, and the emergence of extremists. In the presentation recent work will be presented on (1) the addition of a contrast effect besides assimilation, (2) two attitude dimensions affecting each other, and (3) effects of a meta-actor. The discussion will focus on implications for practice and further research.

• March 19: Alex Brewis (SHESC) Work in progress: bio-cultural approaches to child health and nutrition in Mexico, Arizona, and other interesting places.

• March 26: Rimjhim Aggarwal (School of Sustainability) Resilience of Agro-Ecosystems in India’s Drylands: Role of Technological Lock-ins, Poverty Cycles, and Overzealous Development Policies.

• April 2: Joshua Abbott (School of Sustainability) Dissecting the Tragedy: A Model of Spatial Behavior in the Commons.

• April 9: David Schaefer (School of Social and Family Dynamics) The Dynamics of Young Children’s Peer Networks.

• April 23: Ramiro Berardo (Department of Political Science, University of Arizona)Self-Organizing Policy Networks: Risk, Partner Selection and Cooperation in Estuaries.

• April 30: Mark Neff (Consortium for Science, Policy & Outcomes, NSF Urban Ecology IGERT and School of Life Sciences); Bethany Cutts (Institute Of Sustainability); Kate Darby (School of Human Evolution and Social Change); Libby Larson (School of Life Sciences); Tischa Munoz-Erickson (School of Sustainability); Amber Wutich (School of Human Evolution and Social Change) and Bob Bolin (School of Human Evolution and Social Change) “Does truth flow like water?: The role of social networks in the flow of scientific understandings in a water management controversy.”
