[17] [18] At PLOS One, the median review time has grown from 37 days to 125 days over the first ten years of operation, according to Himmelstein's analysis, done for Nature ...

Negative consequences of rankings are generally well-documented and relate to the performativity of using journal rankings for performance measurement purposes. [20] [21] Studies of methodological quality and reliability have found that "reliability of published research works in several fields may be decreasing with increasing journal rank", [22] contrary to widespread expectations.
A journal's SJR indicator is a numeric value representing the average number of weighted citations received during a selected year per document published in that journal during the previous three years, as indexed by Scopus.
