SONIC lab collaborator Maryam Fazel-Zarandi, Ph. D. candidate in the Department of Computer Science at the University of Toronto, and Hugh Devlin, Yun Huang, and Director Noshir Contractor of the SONIC lab, had a paper entitled “Expert Recommendation based on Social Drivers, Social Network Analysis, and Semantic Data Representation” accepted by the 2nd International Workshop on Information Heterogeneity and Fusion in Recommender Systems (HetRec 2011) held as part of the 5th ACM Conference on Recommender Systems (RecSys 2011).

Yuval Kalish SONIC Speaker Series
Visiting scholar Yuval Kalish will be presenting “Till Stress Do Us Part: Linking Communication networks, Stress and Voluntary Exit in Extreme Contexts” on Monday, August 29, 2011 10:30-11:30 a.m.
Research has linked stress with various withdrawal behaviors, including voluntary exit from groups. research also demonstrated that stress is contagious – it spreads among group members. However, there is no detailed theory or study of the mechanisms by which stress is disseminated by individuals to others in a group. We discuss and empirically test four stress-related processes that explain why some individuals voluntarily leave their group.
Two hundred and seventy-eight individuals (17 groups) in a unique military setting were measured for their communication-network structure and individual stress at three time-points. Using HLM and stochastic actor-oriented models for social networks, we found support for stress-related withdrawal and selection, and for stress-contagion. Managerial implications are discussed.
Yuval Kalish is assistant professor at the Department of Management, Tel Aviv University. His research focuses on the relationship between individual attributes, networks structures and outcomes within and between organizations. He focuses on the modeling of social networks using Exponential Random Graph models (for which he jointly received the most cited paper award in Social Networks) and other analytic techniques. He teaches courses on leadership, conflict management, statistics and network analysis.

SONIC will present paper in San Antonio
SONIC researcher Yun Huang and lab director Noshir Contractor will present their paper entitled “Understanding and Enabling Network Dynamics in Virtual Communities” in San Antonio on August 16th. The presentation will be at the symposium on Dynamics of Virtual Organizations at the annual meeting of the Academy of Management.
MTS studies featured on Army Research Lab Blog
The work of several SONIC researchers including Brooke Foucault Welles, and Tony Vashevko has been featured in the Army Research Lab’s Network Science-Collaborative Technology Alliance Blog. The information can be found after the jump, halfway down the blog under “Multi-Team Systems Simulation”.
Whether it’s emergency relief due to natural disasters or humanitarian aid in war torn regions, there are situations where international organizations, first responders, and military personnel need to collaborate effectively on teams in stressful situations. Researchers at Northwestern University and the University of Illinois at Urbana-Champaign will use the Multi-team System Simulation – or MTS Platform – to gain insight on how network parameters can be configured to better allow small teams to coordinate in such emergency situations.
