To ensure the integrity of the blind peer-review for submission to this journal, every effort should be made to prevent the identities of the authors and reviewers from being known to each other. Reviewers who use the online form to submit their comments can be assured their anonymity is preserved.

If the reviewer decides to submit comments in a separate document, he/she must check to see if the below steps have been taken with regard to the text and the file properties. Likewise, all authors must ensure these steps have been taken to anonymize the manuscript file:

• The authors of the document have deleted their names from the text, with "Author" and year used in the references and footnotes, instead of the authors' name, article title, etc.
• With Microsoft Office documents, author identification should also be removed from the properties for the file (see under File in Word), by clicking on the following, beginning with File on the main menu of the Microsoft application: File > Save As > Tools (or Options with a Mac) > Security > Remove personal information from file properties on save > Save.
• With PDFs, the authors' names should also be removed from Document Properties found under File on Adobe Acrobat's main menu.
