Aug

Aaron M. Schecter, SONIC alumnus and Ph.D. in Industrial Engineering and Management Science, received the 2018 J. Richard Hackman Award for his Ph.D. dissertation at INGroup 2018. The conference recognizes recent graduate students whose dissertation shows the greatest potential to advance the study of groups. His dissertation entitled “It’s About Time: Theorizing the Antecedents and Outcomes of Dynamic Processes in Teams and Multiteam Systems” presented a sophisticated theoretical analysis combined with four controlled experimental studies. The relational event modeling framework provided a new conceptual and methodological approach to studying teams process in Multi-Team Systems. At the award ceremony, Schecter’s dissertation was described as “a clear and innovative interdisciplinary approach by contributing to the advancement of team research methodology.” Dr. Schecter, who is an assistant professor at the Terry College of business at the University of Georgia, received a commemorative plaque, a $1,000 check, and an invitation to present his dissertation in a featured session at the following year’s INGRoup conference, in Portugal.

The SONIC Ph.D. students, Kyouske Tanaka and Diego Gómez-Zará, participated at the Summer Institute in Computational Social Science, in Chicago. The purpose of the Summer Institute was to bring together graduate students and early career researchers in both social science and data science. Content included live-streamed lectures from the main site at Duke University as well as guest speakers who presented on cutting-edge computational research and methods. Topics covered include text analysis, digital data collection, experimental design, non-probability sampling, agent-based modeling, and ethics.

How network theory predicts the value of Bitcoin

07
May

A recent research by Spencer Wheatley at ETH Zurich in Switzerland and a few colleagues shows that the key measure of value for cryptocurrencies is the network of people who use them. What’s more, they say, once Bitcoin is valued in this way it becomes possible to see when it is overvalued and perhaps even to spot the telltale signs that a market crash is imminent.

On April 9th, Professor Noshir Contractor and his Ph.D. student Diego Gómez-Zará presented the results of the team assembly case study conducted at the Center for Technological and Pedagogical Innovation (CITEP – Centro de Innovación en Tecnología y Pedagogía). The talk was given at the University of Buenos Aires in Buenos Aires, Argentina. Noshir and Diego presented how the participants of this academic program searched and invited others to assemble teams. The main results explain the relevant features for creating effective teams and demonstrate how My Dream Team –a web-based teaming search platform– facilitate the formation of teams in educational contexts.

Population structured by witchcraft beliefs

24
Jan

Anthropologists have long argued that fear of victimization through witchcraft accusations promotes cooperation in small-scale societies. Others have argued that witchcraft beliefs undermine trust and therefore reduce social cohesion. However, there are very few, if any, quantified empirical examples demonstrating how witchcraft labels can structure cooperation in real human communities. Here we show a case from a farming community in China where people labelled zhu were thought capable of supernatural activity, particularly poisoning food. The label was usually applied to adult women heads of household and often inherited down the female line. We found that those in zhuhouseholds were less likely to give or receive gifts or farm help to or from non-zhu households; nor did they have sexual partnerships or children with those in non-zhu households. However, those in zhuhouseholds did preferentially help and reproduce with each other. Although the tag is common knowledge to other villagers and used in cooperative and reproductive partner choice, we found no evidence that this assortment was based on cooperativeness or quality. We favour the explanation that stigmatization originally arose as a mechanism to harm female competitors. Once established, fear that the trait is transmissible may help explain the persistence of this deep-rooted cultural belief. Source: Nature
