Are All Successful Communities Alike? Characterizing and Predicting the Success of Online Communities

Tiago Cunha, David Jurgens, Chenhao Tan, Daniel Romero
2019 The World Wide Web Conference on - WWW '19  
Our work sheds light on the basic understanding of what success represents in online communities and what predicts it.  ...  We identify four success measures that are desirable for most communities: (i) growth in the number of members; (ii) retention of members; (iii) long term survival of the community; and (iv) volume of  ...  ACKNOWLEDGMENTS This research was partly supported by the National Science Foundation under Grant No. IIS-1617820.  ...

Preverbal infants expect members of social groups to act alike

L. J. Powell, E. S. Spelke
2013 Proceedings of the National Academy of Sciences of the United States of America  
Across a series of experiments, we show that by 7 months of age preverbal infants differentiate between actions by individuals that are and are not consistent with the actions of their social group members  ...  This expectation is consistent with the socially motivated imitation and stereotyping evident in toddlers and preschoolers, and may play a role in the early emergence of one or both of these aspects of  ...  We thank the Harvard Laboratory for Developmental Studies and the families who participated.
