How do social networks affect the spread of behavior. [] Key Result The behavior spread farther and faster across clustered-lattice networks than across corresponding random networks.

Information diffusion and social influence in online networks

The explosive growth of online social systems has changed how individuals consume and disseminate information. In this thesis, we conduct large-scale observational and experimental studies that allow

Choosing your network: social preferences in an online health community.

Social Influence in the Concurrent Diffusion of Information and Behaviors in Online Social Networks

Examining the concurrent spread of information and behaviors related to the Ice Bucket Challenge on Twitter shows that the two processes follow different patterns, which have implications for theories of social influence, social networks, and contagion.

The Impact of Influence on the Dynamics of Complex Information Cascades

This project aims to extend current research on the dynamics of complex information transmission by adding variation in influence across a navigable, small-world network model by comparing the results of the simulated cascades to a cascade of retweets on the Twitter network.

Social Features of Online Networks: The Strength of Intermediary Ties in Online Social Media

This work focuses on Twitter, one of the most popular online social networks, and finds that the network formed by the basic type of connections is organized in groups, and the activity of the users conforms to the landscape determined by such groups.

Potential networks, contagious communities, and understanding social network structure

This model and results provide an alternate explanation for certain properties repeatedly observed in data sets, for example: heavy-tailed degree distribution, network densification, shrinking diameter, and network community profile.

Identifying Social Influence in Networks Using Randomized Experiments

Understanding how people influence or are influenced by their peers can help to understand the ebb and flow of market trends, product adoption and diffusion, the spread of health behaviors, the productivity of information workers, and whether particular indi viduals in a social network have a disproportion ate amount of influence on the system.

Investigating the Observability of Complex Contagion in Empirical Social Networks

This work shows an alternative method for fitting probabilistic complex contagion models to empirical data that avoids measuring thresholds directly, and results indicate bias in observed thresholds under both complex and simple models.

Methods for Inferring Health-Related Social Networks among Coworkers from Online Communication Patterns

Evaluating methods for using online communication data to generate comprehensive network maps that reproduce the health-associated properties of an offline social network demonstrated that logistic regression predicted the greatest proportion of offline social ties, thresholding on number of emails exchanged produced the best match to offline network metrics, and ranked email partners demonstrated the strongest autocorrelation of BMI.

The role of social networks in information diffusion

It is shown that, although stronger ties are individually more influential, it is the more abundant weak ties who are responsible for the propagation of novel information, suggesting that weak ties may play a more dominant role in the dissemination of information online than currently believed.



The collective dynamics of smoking in a large social network.

Despite the decrease in smoking in the overall population, the size of the clusters of smokers remained the same across time, suggesting that whole groups of people were quitting in concert.

Birds of a Feather: Homophily in Social Networks

Similarity breeds connection. This principle—the homophily principle—structures network ties of every type, including marriage, friendship, work, advice, support, information transfer, exchange,

Origins of Homophily in an Evolving Social Network1

The authors investigate the origins of homophily in a large university community, using network data in which interactions, attributes, and affiliations are all recorded over time. The analysis

Empirical Analysis of an Evolving Social Network

This work analyzed a dynamic social network comprising 43,553 students, faculty, and staff at a large university, in which interactions between individuals are inferred from time-stamped e-mail headers recorded over one academic year and are matched with affiliations and attributes.

The spread of obesity in a large social network over 32 years.

Network phenomena appear to be relevant to the biologic and behavioral trait of obesity, and obesity appears to spread through social ties, which has implications for clinical and public health interventions.

The Strength of Weak Ties

Analysis of social networks is suggested as a tool for linking micro and macro levels of sociological theory. The procedure is illustrated by elaboration of the macro implications of one aspect of

Small worlds: the dynamics of networks between order and randomness

Everyone knows the small-world phenomenon: soon after meeting a stranger, we are surprised to discover that we have a mutual friend, or we are connected through a short chain of acquaintances. In his

Social Networks and Health

It is concluded that the existence of social networks means that people's health is interdependent and that health and health care can transcend the individual in ways that patients, doctors, policy makers, and researchers should care about.

Complex Contagions and the Weakness of Long Ties1

The strength of weak ties is that they tend to be long—they connect socially distant locations, allowing information to diffuse rapidly. The authors test whether this “strength of weak ties”

Contagious Collectivities: On the Spatial Diffusion of Swedish Trade Unions, 1890-1940

This article how distances and relations between actors are likely to influence the growth and spread of social movements. A formal theoretical model is developed that extends previous work on
