Online communities suffer from the 1-9-90 principle, which states that 1% of the community's user base generates original content, an additional 9% is limited to interacting with existing content, while the remaining 90% of the participants is passively lurking.

For the first time the global extent of a mid stratospheric new particle layer is addressed, using the National Center for Atmospheric Research Community Earth SystemModel, version 1 (CESM1), with the high-top atmosphere component, the Whole Atmosphere Community Climate Model (WACCM). The CESM1(WACCM) version has been configured for pure sulfate formation in the stratosphere, including the form...

in this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. the model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. by using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. ...

Social susceptibility is defined and analyzed using data from CNN news website. The current models of opinion dynamics, voting, and herding in closed communities are extended, and the community’s response to the injection of a group with predetermined and permanent opinions is calculated. A method to estimate the values of possible response in Internet communities that follow a specific develop...
