R/data_ison.R
ison_physicians.RdRon Burt prepared this data from Coleman, Katz and Menzel's 1966 study on medical innovation. They had collected data from physicians in four towns in Illinois: Peoria, Bloomington, Quincy and Galesburg. These four networks are held as separate networks in a list.
Coleman, Katz and Menzel were concerned with the impact of network ties on the physicians' adoption of a new drug, tetracycline. Data on three types of ties were collected in response to three questions:
advice: "When you need information or advice about questions of therapy where do you usually turn?"
discussion: "And who are the three or four physicians with whom you most often find yourself discussing cases or therapy in the course of an ordinary week – last week for instance?"
friendship: "Would you tell me the first names of your three friends whom you see most often socially?"
Additional questions and records of prescriptions provided additional information:
recorded date of tetracycline adoption date
years in practice
(note that these are {messydates}-compatible dates)
conferences attended
(those that attended "Specialty" conferences presumably also attended "General" conferences)
regular subscriptions to medical journals
free_time spent associating with doctors
discussions on medical matters when with other doctors sociallyy
memberships in clubs with other doctores
number of top 3 friends that are doctors
time practicing in current community
patients load (ordinal)
physical proximity to other physicians (in building/sharing office)
medical specialty (GP/Internist/Pediatrician/Other)
