Simmilar to the Galesburg drug study network, these is a network that represents discussion ties between 31 physicians who adopted a new drug in Galesburg (Illinois).
It is one of the two parts of the Galesburg Drug Study 2 dataset. The second part is Galesburg Drug Study 2 Friendship.

Background:

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.
