Dissemination of Health Information within Social Networks

In this paper, we investigate, how information about a common food born health hazard, known as Campylobacter, spreads once it was delivered to a random sample of individuals in France.

Sharing the News: Effects of Informational Utility and Opinion Leadership on Online News Sharing

This study examined the joint effect of message and personality attributes on online news sharing.
