Interorganizational Search and Rescue Networks (Drabek et al.)
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.
data(emon)
A list of 7 network objects:
| [[1]] | Cheyenne | network | Cheyenne SAR EMON |
| [[2]] | HurrFrederic | network | Hurricane Frederic SAR EMON |
| [[3]] | LakePomona | network | Lake Pomona SAR EMON |
| [[4]] | MtSi | network | Mt. Si SAR EMON |
| [[5]] | MtStHelens | network | Mt. St. Helens SAR EMON |
| [[6]] | Texas | network | Texas Hill Country SAR EMON |
| [[7]] | Wichita | network | Wichita Falls SAR EMON |
Each network has one edge attribute:
| Frequency | numeric | Interaction frequency (1-4; 1=most frequent) |
Each network also has 8 vertex attributes:
| Command.Rank.Score | numeric | Mean rank in the command structure |
| Decision.Rank.Score | numeric | Mean rank in the decision process |
| Formalization | numeric | Degree of formalization |
| Location | character | Location code |
| Paid.Staff | numeric | Number of paid staff |
| Sponsorship | character | Sponsorship type |
| vertex.names | character | Organization name |
| Volunteer.Staff | numeric | Number of volunteer staff |
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:
Mean (reversed) rank for the prominence of each organization in the command structure of the response, as judged by organizational informants.
Mean (reversed) rank for the prominence of each organization in decision making processes during the response, as judged by organizational informants.
An index of organizational formalization, ranging from 0 (least formalized) to 4 (most formalized).
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.
Number of paid staff employed by each organization at the time of the response.
The level at which each organization
was sponsored (e.g., "City", "County",
"State", "Federal", and "Private").
The identity of each organization.
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).
