Network analysts seem to be taking over the NYTimes.
Just yesterday, March 16, I saw the following:
1.Op-Ed piece by Scott Atran extensively and positively discussing
Kathleen Carley and Bob Axelrod.
"Carley ... has used intelligence data and computer modeling to monitor
changes in jihadist networks, including the cell responsible for the
suicide bombing of the American Embassy in Tanzania. She found that
eliminating the `central actors' -- that is, cell members who have the
most ties toother cell members and to other groups -- has actually spurred
terrorists to adapt more quickly, and has been less effecitve in the long
run than eliminating less-central foot soldiers."
2. Valdis Krebs' Amazonish research into book buying networks (using
Amazon's people who have bought X, have also bought Y,Z,...) apparently
was discussed March 13. No less than 4 letters were printed in the March
16 Times, most of whom missed the point and saw book networks and
tightly-bounded groups. They bemoaned the alleged fact that people tended
to read within tightly-bounded intellectual orbits. But in fact, although
networks certainly do cluster, they often are less bounded and more
heterogeneous. I.e., they are leakier than groups.
