This journal uses double-blind review, which means that both the reviewer and author identities are concealed from the reviewers, and vice versa, throughout the review process.
To facilitate this, authors need to ensure that their manuscripts are prepared in a way that does not give away their identity. To help with this preparation please ensure the following when submitting: Please submit the Title Page containing the Authors details and Blinded Manuscript with no author details as 2 separate files. This should include the title, authors' names and affiliations, and a complete address for the corresponding author including e-mail address.

Preliminary evaluation.
All manuscripts submitted for publication must go through the review process. All manuscripts are initially treated by editors to assess their compliance with the requirements of the journal and the subject. Incomplete packages or manuscripts not prepared in the advised style will be sent back to author(s) with suggestions for correction. The authors are notified with the reference number upon manuscript registration at the Editorial Office.
The Editor-in-Chief or Editor reads every manuscript received and assigns a general priority level:
(a) manuscripts sent to reviewers immediately;
(b) manuscripts returned to authors with suggestions for the correction of data presentation;
and (c) rejected manuscripts.
Editors read the revised manuscript. If the manuscript is improved adequately, it is sent to two (or more) reviewers for review and to the Statistical Editor, if it contains numerical data. The preliminary evaluation process usually takes 3 weeks.
