madrid_bombing_jjatt — Madrid train bombing network, JJATT (2004)

Description

Time series of networks of relationships among 54 individuals, from the John Jay & ARTIS Transnational Terrorism Database (JJATT). The JJATT data treat specific attacks as endpoints, and depict the evolution of the relations among the individuals directly or indirectly associated with them; here, the bombings of commuter trains in Madrid, Spain, on 11 March 2004 (Wikipedia). The data were coded from open sources (e.g. court documents, news reports and books), and were made available in matrix form by the UCINET datasets collection (University of Manchester).

Nodes are individuals (labelled by their JJATT identifier in name), and each time-period network contains the relationships present in that period (networks named YYYY_1 and YYYY_2 refer to the first and second halves of year YYYY). The edge property weight gives the strength of the tie: 1 = acquaintances or distant family ties (interaction limited to radical organisation activities), 2 = friends or moderately close family ties (including co-workers and roommates), operational or organisational leadership, or operational ties (e.g. having worked closely together on a bombing), 3 = close friends or family, tight-knit operational cliques. The periods 2005_2, 2006_1, 2006_2 have no ties in the source, and are not included. The kinship network contains kinship ties, with the edge property kinship coding the type: 1 = in-laws, 2 = cousins, 3 = siblings, 4 = parent/child, 5 = married, 6 = grandparent/grandchild, 7 = significant other (cells coded 99 in the source matrix, whose meaning is not documented, are omitted). The source matrices are meant to be symmetric; in the few cases where the two directions differ, the tie with the larger value is used. The JJATT tie-start, tie-end and operation matrices, which use undocumented codes, are not included.1
