Contributors publishing their research in PRJ are required to agree to the terms and conditions as follows:

1. Copyright Retention: While the work is simultaneously licensed under the Creative Commons Attribution 4.0 International License (CC‑BY), which permits others to share the work with a citation to the work’s authorship and first publication in this journal, the authors retain copyright and grant the journal the right of first publication.

2. Additional Distribution: With an acknowledgement of the work’s original publication in this journal, authors can sign additional, independent contracts for the non‑exclusive distribution of the journal’s published version of the work (for example, posting it to an institutional repository or publishing it in a book).

3. Online Posting: Because it may result in fruitful interactions and earlier and more extensive citation of published work, authors are allowed and encouraged to post their work online (for example, on their website or in institutional repositories) both before and during the submission process.
