TitleShanghai Rotary Club: one-mode network of co-attendance (1930-1931)
Year Start1930
Year End1931
DateSunday 15 September 2019
Description

This table provides the original dataset I used to build the one-mode network of co-attendance at the meetings of the Shanghai Rotary Club under President Fitch's term (1930-31). This network of persons-persons joined by events results from the projection of the initial two-mode network of meeting attendance (see related data below), using the R package tnet (project_tm function) (Opsahl, 2008). In this network, nodes represent participants (persons who attended meetings), whereas edges represents events. Any edge links two persons who participate in the same events. 

The data in this table is presented as a four-column edge list. The first two columns contain connected nodes (persons), while the third and four columns indicate tie weight, using two different methods (sum and Newman). Edges weights measure how frequently two persons co-participate in meetings. In the “sum” projection, 1 means they met only once, 2 that they attend twice the same meeting, 3 three times, and so on. In Newman projection, it is more complex since the method means to correct the negative effects of size variation – by discounting most important events that are more likely to be attended than smaller events, and key officers that are more likely to attend compared to less active members, occasional guests and visitors. 

The first sheet includes the edge list, and the second one contains the correspondance table between persons' id, names and personal attributes. 

N.B. In this network, edges represent co-attendance but not necessarily direct interaction. A major limitation of such one-mode projection is that it creates direct ties between persons without discriminating between mere co-presence and active interaction. Two persons may attend the same event without interacting directly. Yet they will be treated in the same way as two attendees engaged in active intercourse.
