摘要
We analyze the temporal 演化 of emerging fields within several scientific disciplines in terms of numbers of authors and publications. From bibliographic searches we construct databases of authors, papers, and their dates of publication. We show that the temporal development of each field, while different in detail, is well described by 族群 contagion models, suitably adapted from 流行病學 to reflect the dynamics of scientific interaction. Dynamical parameters are estimated and discussed to reflect fundamental characteristics of the field, such as time of apprenticeship and recruitment rate. We also show that fields tire characterized by simple 縮放律 laws relating numbers of new publications to new authors, with exponents that reflect increasing or decreasing returns in scientific productivity.
