JOURNALS OF NAS OF UKRAINE IN PHYSICAL, ENGINEERING AND MATHEMATICAL SCIENCES: MONOPOLIZATION LEVEL

This is the third article in the cycle of publications on the monopolization level of scientific periodicals of National Academy of Sciences of Ukraine. It is devoted to the journals of Section of Physical, Engineering and Mathematical Sciences. The paper finishes the first stage of research aimed at revealing the breadth of the authors’ community of the NAS of Ukraine journals during 2015–2017. As well as in the previous articles of this cycle, the estimation of the authors’ community and its monopolization level is made by the Herfindahl–Hirschman Index calculation. Thus, the quantitative weighted distribution of affiliation is made for each journal. The analysis of the journals of Section of Social Sciences and Humanities and the Section of Chemical and Biological Sciences is made in the articles previously published in the “Herald of the National Academy of Sciences of Ukraine” (2018, No. 9 and 2019, No. 10). It was shown that the chemical and biological journals of NAS of Ukraine have the lowest monopolization level — there are only 23% of middle-monopolized and 27% of low-monopolized ones. Meanwhile, only 19% of journals of the Section of Social Sciences and Humanities have the moderate monopolization level and the rest have the high one. Journals of the Section of Physical, Engineering and Mathematical Sciences are more like chemical and biological ones. They mostly have high monopolization level (54%), however 17% are moderately monopolized and 25% are low-monopolized.
Keywords: scientific journal, Herfindahl–Hirschman Index, scientific periodicals monopolization, affiliation, breadth of the authors’ community.
