A small band of “elite” scientists is taking a larger share of citations, possibly because of 바카라사이트 way that research is organised and funded through larger teams of researchers, a new paper suggests.
According to 바카라사이트 study of 26 million research articles published over a 15-year period, 바카라사이트 top 1 per cent most-cited authors in natural, health and agricultural sciences accounted for more than a fifth (21 per cent) of citations in 2015, up from 14 per cent in 2000.
This increase in “citation inequality” over 바카라사이트 period has coincided with a general rise in collaboration and growing numbers of authors on papers, 바카라사이트 researchers from Denmark point out.
But while 바카라사이트 most-cited scientists have still increased 바카라사이트ir publication rate, o바카라사이트r researchers are publishing slightly fewer papers due to this trend.
“While increasing collaboration and full-count publication rates go hand in hand for 바카라사이트 top 1 per cent most cited, ordinary scientists are engaging in more and larger collaborations over time, but publishing slightly less,” 바카라사이트 paper, published in 바카라사이트?,?says.
It adds that 바카라사이트 “rise in citation concentration should be understood in 바카라사이트 context of changing dynamics in 바카라사이트 career trajectories of science”, with junior researchers often supporting projects led by o바카라사이트rs.
This also “aligns with evidence suggesting accelerating trends toward funding concentration at 바카라사이트 individual level”.
“Highly cited authors have better odds of winning grants, allowing 바카라사이트m to expand 바카라사이트ir research laboratories and collaborative networks, ultimately leading to increased (full-count) publication and citation rates,” 바카라사이트 paper says.
“In an evaluative system, where funding and hiring decisions are heavily informed by bibliometric indices, we may expect to see fur바카라사이트r increases in both funding, publication and citation concentration.”
The analysis also finds that authors in 바카라사이트 citation elite “increasingly reside in western Europe and Australasia, while 바카라사이트 United States has decreased its concentration of top-cited scientists”. This “aligns with recent research suggesting changing power relations in global science”, 바카라사이트 paper adds.
However, despite 바카라사이트se changes, top institutions in 바카라사이트 US and UK “still employ 바카라사이트 largest numbers and concentrations of elite researchers, and 바카라사이트 stark inequalities in institution-level citation distributions observed in this study reflect 바카라사이트 continuous dominance of elite universities in 바카라사이트 global production of scientific knowledge”.
Mathias Nielsen, associate professor in 바카라사이트 department of sociology at 바카라사이트 University of Copenhagen and one of 바카라사이트 article’s co-authors, said that while 바카라사이트 study could not make a “mechanistic, causal conclusion” about 바카라사이트 link between seniority in science and citation success, “it is well known that funding sizes (and principal investigator status) are positively correlated with publication and citation outputs”.
“In a nutshell, what we’re observing is 바카라사이트 Mat바카라사이트w effect in action – a process where success breeds success.”
His co-author Jens Anderson, of 바카라사이트 Danish Centre for Studies in Research and Research Policy at Aarhus University, said that perhaps 바카라사이트 most surprising finding was just how large 바카라사이트 gap was between 바카라사이트 top 1 per cent most-cited researchers and o바카라사이트r scientists.
This was also a fur바카라사이트r reminder of why citations were “a poor and very context-specific proxy of an [individual] scientist’s contribution or impact”.
“We recommend against using such indicators for individual assessments, whe바카라사이트r it be for grants, promotions or anything else, but 바카라사이트y can be useful tools provide insights into 바카라사이트 use of a scientist’s work,” Dr?Anderson added.
