R Documentation
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:
Command.Rank.Score
Mean (reversed) rank for the prominence of each organization in the command structure of the response, as judged by organizational informants.
Decision.Rank.Score
Mean (reversed) rank for the prominence of each organization in decision making processes during the response, as judged by organizational informants.
Formalization
An index of organizational formalization, ranging from 0 (least formalized) to 4 (most formalized).
Localization
For each organization, "L" if the organization was sited locally to the impact area, "NL" if the organization was not sited near the impact area, "B" if the organization was sited at both local and non-local locations.
Paid.Staff
Number of paid staff employed by each organization at the time of the response.
Sponsorship
The level at which each organization was sponsored (e.g., "City", "County", "State", "Federal", and "Private").
vertex.names
The identity of each organization.
Volunteer.Staff
Number of volunteer staff employed by each organization at the time of the response.
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).
