“Local and Global Network Characteristics: The Paradox of the Paradox of Friends”
Speaker: Vineet Kumar
Assistant Professor of Marketing, Yale School of Management
joint work with David Krackhardt (Carnegie Mellon University) and Scott Feld (Purdue University)
The Paradox of Friends states that, on average, people have fewer friends than their friends do. Moreover, it has been shown that, as long as there is some variance in the number of friends in the network, this claim is true for any and all possible networks. However, we demonstrate that this paradox leads to a second inescapable paradox. We resolve the second paradox and demonstrate previously unexamined approaches to applications leveraging the friendship paradox.
“Networks, Conversational Characteristics, and How We Coordinate Health Care: Evidence from a Field Experiment”
Speaker: Marissa King
Associate Professor of Organizational Behavior, Yale School of Management
Ingrid Nembhard, Ira V. Hiscock Associate Professor of Public Health, Yale School of Public Health
Using data collected from sociometric sensors, we observe a strong and persistent relationship between network position and speaking volubility, listening, and interruptions. Through a field experiment designed to improve health care coordination, we find that shifting power from doctors to nurses has a significant effect on both network position and conversational characteristics which are in turn associated with health care outcomes and organizational turnover. This work provides insight into the unanticipated consequences that micro-level social networks can have in mediating planned change initiatives.
