Table 2.

Journal-specific network structure. We present the same information as in Table 1 for each of the journals studied. We ranked journals within each field according to their impact factor (IF). For some low-impact journals, the f_R is too high to be reproducible with the model. In those cases, which we represent by q > 1, simulations of the model are done with q = 1. The model still reproduces the empirical results quite well for these cases.
