Dec 11, 2018 – SONIC summer intern, Cameron DeChurch, presented at the 7th International Conference on Complex Networks and Their Applications. This summer he used historical records to construct digital networks of the collaboration among Florentine Renaissance painters. His paper with Noshir Contractor, “Using Network Science to Discover the Grand Masters of the Florentine Renaissance” finds that rather than the household names of Michelangelo and DaVinci, it was the grand masters like Verrochio and Perugino who ultimately had more impact through their lineage, by training painters who would go on to produce great works.

When Lebron James, Dwyane Wade, and Chris Bosh signed with the National Basketball Association’s (NBA) Miami Heat in 2010 as free agents, basketball fans and sports pundits heralded the arrival of the league’s first “super team.” Yet despite boasting a starting lineup featuring three of the league’s best players, the Heat began the 2011 season with a disappointing 9-8 record as its stars acclimated to their new roles as teammates.

Looking back at the team’s inauspicious start, Northwestern Engineering’s Noshir Contractor isn’t surprised.

“Of course, individual players on a team make a difference, but so much focus is spent on finding those with the most talent,” Contractor said. “Other factors, like how people get along together or how well they trust each other, suggest that teams are not just an aggregation of individuals and their attributes, but also the relationships that exist previously among them.”

Contractor, the Jane S. and William J. White Professor of Behavioral Sciences and professor of industrial engineering and management sciences in the McCormick School of Engineering, worked with a team of researchers to put this paradigm to the test. Analyzing statistical data from professional sports leagues and online games, the group has found that past shared success among team members improves their odds of winning future games — findings that have implications far beyond the sports arena, into business and even space research.

The study, titled “Prior shared success predicts victory in team competitions,” was published December 3 in the journal Nature Human Behaviour. Satyam Mukherjee, assistant professor at the Indian Institute of Management Udaipur and former postdoctoral fellow within the Northwestern Institute on Complex Systems, served as the paper’s corresponding author. Contractor and Brian Uzzi, Richard L. Thomas Professor of Leadership and Organizational Change at the Kellogg School of Management and (by courtesy) industrial engineering and management sciences at Northwestern Engineering, were the paper’s co-authors.

Brent Hoagland, lab manager, presented his master’s thesis, “The Plumbing of Wall Street: a case study of a hedge fund’s back-office,” at the Futures of Finance and Society Conference at the University of Edinburgh.

At the North American Regional Social Networks (NASN) Conference of the International Network for Social Network Analysis (INSNA) in Washington, D.C., Contractor spoke as a panel member to discuss common and complementary themes, approaches, and open problems across the major field of network sciences — primarily focussing on the bridges between social network analysis (SNA) and network science (NS), but also addressing other fields such as complex systems (CS), computational social science (CSS) and areas of computer and information sciences (CS, IS).

Professor Krackhardt of Carnegie Mellon guest lectured the Master of Science in Analytic’s class. Krackhard pioneered the concept of “cognitive social structures.” In the lecture, he shared some of his case studies and discussed how an individual’s power can be measured according to his/her position in the whole network structure. He provided network visualizations and demonstrated how they can provide better insights into analyzing an individual’s power.
