The following is an excerpt.
Key scientists, members of the Scientific Advisory Board, and the Chair of SFI CASA´s Board are ranked among the World’s 2 per cent best researchers.
The ranking is made by Stanford University researchers in collaboration with the publishing house Elsevier and SciTech Strategies. Nearly 160 000 of the most influential people of science in the World are on the list, according to how often others quote them and in which journals these citations appear. The two per cent highest ranked in each field have come with.
160 RESEARCHERS FROM NTNU
948 of these scientists work at Norwegian universities and research institutions. Out of the 160 listed from NTNU, about a quarter are in the Engineering field. Four of these belong to the SFI CASA Core Team: Professors Magnus Langseth, Tore Børvik and Odd Sture Hopperstad. In addition, Professor Knut Marthinsen is listed among the 25 scientists in the «Enabling & Strategic Technology» category at NTNU. The Centre´s Chair of the Board, Professor Olav Bolland, is also listed in this field. Bolland is Dean at the Faculty of Engineering at NTNU.
The Scientific Advisory Board of CASA is also well represented: Professor Stefanie Reese (Aachen University, Germany), Professor Em. David Embury (Mc. Master University Canada), Professor Jonas Faleskog (Royal Institute of Technology Sweden), Professor Norman Fleck (University of Cambridge, UK), and Professor John Hutchinson (Harvard University USA) are all on the Stanford-list.
CITRATION METRICS – USED AND MISUSED
Citation metrics are widely used and misused. Also, rankings often give rise to discussions and remarks of shortcomings.
Until 2019, there had been no databases that systematically ranks the most cited scientific researchers per field of science on a broad basis. August 2019, Dr John P.A Ioannidis at Stanford University published an analysis based on Scopus’s scientific citation database. Ioannidis and his co-authors used five citation metrics to rank the scientists from 22 scientific fields and 176 subfields:
- Coauthorship-adjusted hm-index
- Citations to papers in various authorship positions
- A composite indicator
GREAT INTEREST – URGED TO UPDATE
There was great interest in this first publication, and the authors report that many scientists have urged them to provide updates of the databases. Now they have, and their updated study recently appeared in the journal PLOS Biology. The authors use citations from Scopus with data freeze as of May 6, 2020. There are two tables. One is assessing scientists for career-long citation impact until the end of 2019. The other one assesses for citation impact during the single calendar year 2019.
MORE MEANINGFUL COMPARISONS
The authors report that they have added a new extension that allows more comprehensive samples of top-cited scientists for fields with low citation densities. As they write: «Comparisons of citation metrics are more meaningful when done within the same subdiscipline. Of course, even within the same subdiscipline, different areas may still possess different citation densities, and assessing citation indicators always requires caution».
