As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.

• The submission has not been previously published, nor is it before another journal for consideration (or an explanation has been provided in Comments to the Editor).
• All author information such as names, contact information, and affiliations has been removed from the main article text. The authors may provide their information in the title page.
• Where available, URLs for the references have been provided.
• The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines.
• The submission file is in OpenOffice, Microsoft Word, PDF, or RTF document file format.
• The text is single-spaced; uses a 12-point font; employs italics, rather than underlining (except with URL addresses); and all illustrations, figures, and tables are placed within the text at the appropriate points, rather than at the end.
