The study maps the penetration of so-called "predatory" scholarly journals into the citation database Scopus. Predatory journals exploit the author pays open access model, and conduct only cursory or no peer review, despite claims to the contrary.
Some such journals will publish almost anything for money. In the Czech context whether a journal is indexed in Scopus is crucial for determining the points that publications in that journal are awarded in the national performance-based evaluation of research organizations, which in turn is the basis for the allocation of institutional funding.
Hence, in this evaluation framework, publishing in predatory journals that are indexed in Scopus has a clear "fiscal" advantage.
