emon: Interorganizational Search and Rescue Networks (Drabek et al.)

Description

Drabek et al. (1981) provide seven case studies of emergent multi-organizational networks (EMONs) in the context of search and rescue (SAR) activities. Networks of interaction frequency are reported, along with several organizational attributes.

Details

All networks collected by Drabek et al. reflect reported frequency of organizational interaction during the search and rescue effort; the (i,j) edge constitutes i's report regarding interaction with j, with non-adjacent vertices reporting no contact. Frequency is rated on a four-point scale, with 1 indicating the highest frequency of interaction. (Response options: 1=continuously, 2=about once an hour, 3=every few hours, 4=about once a day or less) This is stored within the "Frequency" edge attribute.

For each network, several covariates are recorded as vertex attributes:

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Note that where intervals were given by the original source, midpoints have been substituted. For detailed information regarding data coding and procedures, see Drabek et al. (1981).
