Open Access Policy
Articles are freely available to both subscribers and the wider public with permitted reuse. All articles published in Open Access will be immediately and permanently free for everyone to read and download. Permitted reuse is defined by Creative Commons user license:

Creative Commons Attribution (CC BY): lets others distribute and copy the article, to create extracts, abstracts, and other revised versions, adaptations or derivative works of or from an article (such as a translation), to include in a collective work (such as an anthology), to text or data mine the article, even for commercial purposes, as long as they credit the author(s), do not represent the author as endorsing their adaptation of the article, and do not modify the article in such a way as to damage the author's honor or reputation.

Retraction and Correction Policy
HJSE publishes corrections for errors, made by the journal or authors, of a scientific nature that do not alter the overall basic results or conclusions of a published article. HJSE articles may be retracted by their authors or by the editor because of pervasive error or unsubstantiated or irreproducible data. Articles may be retracted, for example, because of honest error, scientific misconduct, or plagiarism. Errata are published at the discretion of the editors and appear as formal notices in the journal.

Publishing Ethics
HJSE is committed to the highest standards of research and publication ethics. Editors will act in accordance with the COPE guidelines if any ethical misconduct is suspected.
