Research article manuscripts should fit within the range of 6 000 to 12 000 words. When submitting a research article manuscript, please make sure to attach two documents: 1) an anonymised manuscript that doesn't reveal the identity of the author(s) and 2) a title page that includes the author's full name, institutional affiliation, email address, keywords, abstract and acknowledgements (the latter may be added after the successful completion of the peer-review process). Other attachments (data sets, figures etc.) may be uploaded as well if needed. For further information, please refer to our full guidelines.
