This journal provides immediate open access to its content (golden open access) on the principle that making research freely available to the public supports a greater global exchange of knowledge. Open Access should be understood as:

“Permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself."
The Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities

Article Processing Charges

No article submitted will have any submission charges or Article Processing Charges. This includes peer-reviewing, editing, publishing, maintaining and archiving, and allows immediate access to the full-text versions of the articles.


The licensing terms for use and re-use of the published content are permitted under the following user license:

Share (copy and redistribute the material in any medium or format) and adapt (remix, transform, and build upon the material for any purpose, even commercially) are allowed, given appropriate credit. The Journal requests the use of articles' DOIs to reference them.


Authors retain the copyright of their articles. Authors are entitled to deposit their original version (pre-print), the reviewed version (post-print), or the final version in institutional and/or centrally organized repositories and make this publicly available immediately upon publication. The journal encourages authors to deposit the final version instead of the pre-print or post-print versions. This will guarantee that the definitive version is readily available to those accessing the article from such repositories and means it is more likely to be cited correctly (if correct citation details are given).
