Cumhuriyet Science Journal?(note: this journal in indexed by?DOAJ, so it is likely not predatory) is a predatory journal. The title of the journal is included in the archived version of the Beall’s list – a list of potential predatory journals.
Predatory Journals take advantage of authors by asking them to publish for a fee without providing peer-review or editing services.
We recommend that scholars/ researchers read the available reviews, assessments and descriptions of the journal from their end, and then decide for themselves whether they want to submit articles, serve as editors or on editorial boards.
