Open Access Policy

This journal provides ‘Gold’ immediate open access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge. ‘Gold’ open access means the immediate, permanent, and free to access availability of the published version of record on the publisher’s website and with a licence that permits copying and reuse.

All published articles are licensed under the Creative Commons Attribution 4.0 International License. This permits anyone to copy, redistribute, remix, transmit and adapt the work provided the original work and source is appropriately cited (see https://creativecommons.org/licenses/by-nc/4.0/).

The complete bibliographic information (authors, title, journal, volume/issue, articleID), a link to the original publication (URL), as well as this copyright and license information ("Licensed under Creative Commons Attribution CC-BY-NC 4.0") must be included.

There is no need to contact the publisher for "reprint permission" requests because by default this permission has already been given by authors (under the condition of attribution of the original source) and the publisher does NOT own the copyright for the material published, rather, the authors keep the copyright, unless stated otherwise.
