“…Furthermore, we may expect that they may tacitly transfer these skills in turn to their own doctoral students. However, although multiple scholars have suggested that disciplinary backgrounds may provide an indicator of interdisciplinarity (e.g., Bordons, Zulueta, Romero, & Barrigon, 1999;Palmer, 1999), none have rigorously examined this. Furthermore, while scholars have examined academic genealogy and doctoral mentoring with relationship to productivity (e.g., Crosta & Packman, 2005;Malmegren, Ottino, & Amaral, 2010;Sugimoto et al, 2008), they have neglected to utilize the information embedded in academic mentoring networks as potential indicators of interdisciplinarity.…”
