Acceptance of a manuscript for publication carries with it an understanding that the author, when requested, will contribute their expertise to the review of others' manuscripts. Authors unwilling to assist with the review of a colleague's paper may in extreme cases find that their own manuscripts are no longer welcomed for publication.

The Editor first evaluates all manuscripts. It is rare, but entirely feasible, for an exceptional manuscript to be accepted at this stage. Those rejected here are insufficiently original, have serious scientific flaws, have poor grammar or English, or fall outside the aims and scope of the journal. Manuscripts meeting the minimum criteria are passed on to at least two experts for review.

Authors of manuscripts rejected at this stage are informed within two weeks of receipt.

This journal employs single blind review, where the referee remains anonymous throughout the process.

Referees are matched to the paper according to their expertise, drawn from a database that is constantly updated. Suggestions for referees from the author are welcome, though these recommendations may or may not be used.

Referees are asked to evaluate whether the manuscript:

A manuscript is typically reviewed within two months. Should the referees' reports contradict one another, or a report be unnecessarily delayed, a further expert opinion is sought. Revised manuscripts are usually returned to the initial referees within two weeks, and referees may request more than one revision.

A final decision to accept or reject the manuscript is sent to the author along with any recommendations made by the referees, and may include verbatim comments by the referees.

Referees advise the Editor, who is responsible for the final decision to accept or reject the article.
