Any selected referee who feels unqualified to review the research reported in a
manuscript or knows that its prompt review will be impossible should notify the
editor and excuse himself from the review process.

Confidentiality 
Any manuscripts received for review must be treated as confidential documents.
They must not be shown to or discussed with others except as authorized by the
editor.

Standards of Objectivity 
Reviews should be conducted objectively. Personal criticism of the author is
inappropriate. Referees should express their views clearly with supporting
arguments.

Acknowledgement of Sources 
Reviewers should identify relevant published work that has not been cited by
the authors. Any statement that an observation, derivation, or argument had been
previously reported should be accompanied by the relevant citation. A reviewer
should also call to the editor's attention any substantial similarity or overlap between
the manuscript under consideration and any other published paper of which they
have personal knowledge.

Disclosure and Conflict of Interest 
Privileged information or ideas obtained through peer review must be kept confidential
and not used for personal advantage. Reviewers should not consider manuscripts in which
they have conflicts of interest resulting from competitive, collaborative, or other
relationships or connections with any of the authors, companies, or institutions connected
to the papers.
