After an excellent reception of the first issue, here is the second issue of the internationally reviewed scientific journal “ST-OPEN” published by the University of Split. ST-OPEN is an overlay+ journal open to students and teachers from the University of Split, as well as from other universities in Croatia and globally. Since one of the aims of this journal is to increase scientific production and global visibility for the scholarly research of the University of Split, the ST-OPEN editors use an author-helpful policy to transform graduate theses into scientific papers and translated to English without any cost the authors. In addition, the journal is published in a diamond open access form as an e-journal, which publishes articles on a continuous basis using the online first publishing principle. This means that readers can access peer-reviewed articles well before the whole volume is completed.
