Diego Gómez-Zará is going to attend the 13th Annual INGRoup Conference on July 18-22, in Washington, DC. He will present one of the My Dream Team project’s publications called “Social Cognition and Team Assembly: Competence, Warmth, or Embeddedness,” co-authored with Jacqueline Ng, Marlon Twyman, Silvia Andreoli, Leslie DeChurch, and Noshir Contractor.… Read the rest
Sid Jha will give a lightning talk “A Computational Platform to Evaluate the Ability to Perceive Social Connections” at the 2018 Computational Research Day on April 10, 2018. Moreover, Sid and Matt (both Undergraduate Research Assistants at SONIC) will present their posters then, respectively:
Both abstracts and posters are available: http://computational-research-day.s3-website.us-east-2.amazonaws.com/posters/… Read the rest
Hanna Wallach published a thought piece of what computational social science is, especially from her computer science point of view. Given computational social science in mind, She made points of differences between computer science and social science in terms of goals, models, data, and challenges:
A recent study by David Melamed and his colleagues examined whether the emergent structures that promote cooperation are driven by reputation or can emerge purely via dynamics. To answer the research question, they recruited 1,979 Amazon Mechanical Turkers and asked them to play an iterated prisoner’s dilemma game.… Read the rest
Jacqueline Ng, Ph.D. candidate, and Diego Gómez-Zará, Ph.D. student, presented their current research at the ATLAS’s Teams Research Incubator for doctoral students and junior faculty, in Evanston, IL
On March 17th, Jacqueline presented “Information sharing in online teams: How information processing interventions affect team discussions” in a session titled “Multilevel Perspectives on Teams.”
Then, on March 18th, Diego presented his work on team recommender systems: “Social Cognition and Team Assembly:
Competence, Warmth, or Embeddedness.” The session was titled “Perceptions & Teams.… Read the rest
On January 30th, 2018, the Ph.D. Student Diego Gómez-Zará presented at the Kellogg School of Management at Northwestern University. This talk was organized by the program ENLACE
Diego’s talk was titled “The Role of Social Movements in Twitter: Evidence from the Chilean Student Movement”.… Read the rest
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.… Read the rest
Recently Aaron Clauset and his colleague share their new study: “Scale-free networks are rare”. In this study, they found scale-free network structure is not so prevalent based on their statistical analyses of almost 1000 network datasets across different domains. In particular, their results indicate only 4% of the datasets showing the strongest-possible evidence of scale-free structure and 52% demonstrating the weakest-possible evidence.… Read the rest
Recently, Omodei, Brashears, and Arenas published a paper about describing a mechanistic model of human network recall and demonstrate its sufficiency for capturing human recall behavior based on experimental data. They found that human recall is based on accurate recall of a hub of high degree actors and also uses compression heuristics (i.e., schemata simplifying the encoding and recall of social information) for both structural and affective information.… Read the rest
Improving the reliability and efficiency of scientific research will increase the credibility of the published scientific literature and accelerate discovery. Here we argue for the adoption of measures to optimize key elements of the scientific process: methods, reporting and dissemination, reproducibility, evaluation and incentives.
