| Podsumowanie≠ | The Bogardus social distance scale, devised by Emory Bogardus in 1925, measures the degree of acceptance or rejection people feel toward members of other social, ethnic, or national groups. Respondents indicate the closest social relationship they would willingly accept with a target group, across an ordered series ranging from marriage and close friendship through neighbor and coworker down to exclusion from the country. Because the items form a cumulative (Guttman-type) hierarchy, a single score summarizes how much social distance a person places between themselves and each group. | The external-internal (E-I) index, introduced by Krackhardt and Stern, measures the extent to which the ties of a group point outward to other groups versus inward to its own members. It is the number of between-group (external) ties minus the number of within-group (internal) ties, divided by the total number of ties. Ranging from −1 (all ties internal, perfect insularity) to +1 (all ties external), it is a compact summary of homophily and group closure that can be computed for a whole network, for each group, or for each node. |
