In a famous study, known as the Columbia University Drug Study, the
diffusion of a new drug (gammanym) was investigated. The researchers
collected data on the first subscription of this drug by physicians in several
communities. In addition, they investigated friendship ties and discussion
links between the physicians, asking them to name three doctors whom
they considered to be personal friends and to nominate three doctors with
whom they would choose to discuss medical matters.
The file Galesburg.net contains a network of friendship (blue) and
discussion ties (red) between 17 physicians who adopted the new drug in
Galesburg (Illinois) in the 1950s. The partition Galesburg_adoptiontime.clu
specifies the number of months since the introduction of the new drug at
which the physician first prescribed the drug. This is considered to be their
