Recovering from disasters: Social networks matter more than bottled water and batteries
Standard advice about preparing for disasters focuses on building shelters and stockpiling things like food, water and batteries. But resilience – the ability to recover from shocks, including natural disasters – comes from our connections to others, and not from … Continue reading

What Hunter-gatherers can tell us about fundamental Human Social Networks
Long before the advent of social media, human social networks were built around sharing a much more essential commodity: food. Now, researchers reporting on the food sharing networks of two contemporary groups of hunter-gatherers in the Cell Press journal Current … Continue reading

Contagion on Complex Networks with Persuasion
The threshold model has been widely adopted as a classic model for studying contagion processes on social networks. We consider asymmetric individual interactions in social networks and introduce a persuasion mechanism into the threshold model. Specifically, we study a combination … Continue reading

Social Entrepreneurship and Complexity Science – New Collaboration
This paper looks at how ideas, constructs, methods and insights coming out of systems thinking and the sciences of complex systems can be applied to the study of social entrepreneurship. At present, there is no one general theoretical perspective that … Continue reading
Virality Prediction and Community Structure in Social Networks
How does network structure affect diffusion? Recent studies suggest that the answer depends on the type of contagion. Complex contagions, unlike infectious diseases (simple contagions), are affected by social reinforcement and homophily. Hence, the spread within highly clustered communities is … Continue reading

Collective Response of Human Populations to Large- Scale Emergencies
Despite recent advances in uncovering the quantitative features of stationary human activity patterns, many applications, from pandemic prediction to emergency response, require an understanding of how these patterns change when the population encounters unfamiliar conditions. To explore societal response to … Continue reading
Human Mobility, Social Ties, and Link Prediction
Our understanding of how individual mobility patterns shape and impact the social network is limited, but is essential for a deeper understanding of network dynamics and evolution. This question is largely unexplored, partly due to the difficulty in obtaining large-scale … Continue reading

Geographic Constraints on Social Network Groups
Social groups are fundamental building blocks of human societies. While our social interactions have always been constrained by geography, it has been impossible, due to practical difficulties, to evaluate the nature of this restriction on social group structure. We construct … Continue reading

Building an Impact Network
In The New Network Leader series, seven network entrepreneurs—leaders at the heart of some of today’s most sophisticated, large-scale solutions to the world’s social problems—have shared their accounts of catalyzing networks to create powerful social change. Although these networks take … Continue reading

Inequality and Visibility of Wealth in Social Networks
Humans prefer relatively equal distributions of resources, yet societies have varying degrees of economic inequality. To investigate some of the possible determinants and consequences of inequality, here we perform experiments involving a networked public goods game in which subjects interact … Continue reading
