Mathematical Model Analyzes Facebook Networks to Prioritize Who Should Receive Vaccinations
People who are "bridges" among different social groups appear as good vaccination bets
The mathematical model focused on the fact that just a few individuals often form the links between different social groups. It also made use of data that came from back in 2005, when Facebook was only open to college students.
The relationships and interactions on five university campuses provided a useful starting scenario for the model to recognize clusters of people and predict bridges between them.
"When a new virus starts spreading, neither the time nor the necessary doses of vaccine to immunize everyone is available," said Marcel Salathe, a postdoc biology researcher at Stanford University. So you'd want a strategy that allows you to protect a population as much as possible given the limited resources that you have."
More details on the Stanford work appear in the April 8 issue of the PLoS Computational Biology.
Scientists have made growing use of social networking data that contains once-personal info. HP Labs researchers recently announced that they used Twitter data to predict the box office success of the latest Hollywood films. And the Pentagon's DARPA challenged people to sift through the disinformation available on social networks such as Twitter and hunt down the physical location of 10 red balloons located around the U.S.
Discovered a Fake Facebook
PandaLabs has detected a spoof page of Facebook designed to steal passwords from users of social networks. The content and the URL of the web page are identical to the actual page content service so it is very easy to convince a user to enter their name and password. After entering the password an error page which should alert and warn the user that he is on a specially crafted website. For reference you can see the image of this error:
