The spread of true and false news online
A large-scale analysis of tweets reveals that false rumors spread further and faster than the truth, and false news was more novel than true news, which suggests that people were more likely to share novel information.
I.T. Assets, Organizational Capabilities and Firm Performance: Do Resource Allocations and Organizational Differences Explain Performance Variation?
Despite evidence of a positive relationship between information technology (IT) investments and firm performance, results still vary across firms and performance measures. We explore two…

A dynamic matched sample estimation framework is developed to distinguish influence and homophily effects in dynamic networks, and this framework is applied to a global instant messaging network of 27.4 million users, finding that previous methods overestimate peer influence in product adoption decisions in this network by 300–700%, and thathomophily explains >50% of the perceived behavioral contagion.
Introduction to the Special Issue - Social Media and Business Transformation: A Framework for Research
A broad research agenda for understanding the relationships among social media, business, and society is outlined and it is hoped that the flexible framework outlined will help guide future research and develop a cumulative research tradition in this area.
Identifying Influential and Susceptible Members of Social Networks
Analysis of influence and susceptibility together with network structure revealed that influential individuals are less susceptible to influence than noninfluential individuals and that they cluster in the network while susceptible individuals do not, which suggests that influential people with influential friends may be instrumental in the spread of this product in thenetwork.
Creating Social Contagion Through Viral Product Design: A Randomized Trial of Peer Influence in Networks
Although active-personalized viral messages are more effective in encouraging adoption per message and are correlated with more user engagement and sustained product use, passive-broadcast messaging is used more often, generating more total peer adoption in the network.
Life in the network: The coming age of computational social science: Science
Computational Social Science
It is found that origination rates of marine bivalves increased significantly almost everywhere immediately after the K-Pg mass extinction event, and a distinct pulse of bivalve diversification in the early Cenozoic was concentrated mainly in tropical and subtropical regions.
Tie Strength, Embeddedness, and Social Influence: A Large-Scale Networked Experiment
This work presents some of the first large-scale in vivo experimental evidence investigating the social and structural moderators of peer influence in networks, and finds that both embeddedness and tie strength increase influence.
Social Influence Bias: A Randomized Experiment
A large-scale randomized experiment on a social news aggregation Web site was designed and analyzed to investigate whether knowledge of such aggregates distorts decision-making, and found positive herding was topic-dependent and affected by whether individuals were viewing the opinions of friends or enemies.
