An approximation of a researcher's functioning in global science is having at least one publication indexed in the Scopus database in the analyzed decade 2009–2018. Thus, using the example of comprehensive data from the entire national system of science, we estimate the extent of limitations of using academic age as a proxy for biological age depending on selected independent variables and analyze both the practical and methodological implications of using academic age in academic career research, which is one of the most important components of quantitative studies of science.}, type={Artykuły / Articles}, title={Global science and academic age of Polish researchers}, URL={http://journals.pan.pl/Content/123127/PDF-MASTER/N%23222-02-Kwiek.pdf}, doi={10.24425/nauka.2022.140330}, keywords={global science, academic age, sociology of science, quantitative science studies, science of science, publishing patterns, academic profession}, }
