A particular interesting way to detect invisible colleges in scientific fields is to study acknowledgements in research publications. Authors usually thank their colleagues who spent time and effort to provide a “friendly review” of earlier drafts of the manuscript, or who have given other forms of support. When these efforts are reciprocated, networks of professional ties among scholars rise to the surface.
Sometimes acknowledgements reveal more than just professional networks. A Canadian paleontologist has recently published a paper in which he gives credit to the support from his colleague Lorma, who holds a PhD from the same university. So far, so good, but the acknowledgements continue surprisingly: “Lorma, will you marry me?” See the full CBC news report.
