Contribution to Editorial Decisions 
The peer-reviewing process assists the editor and the editorial board in making editorial decisions and may also serve the author in improving the paper. 

Promptness 
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 withdraw from the review process. 

Confidentiality 
Any manuscripts received for review must be treated as confidential documents. They must not be disclosed 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 cases in which relevant published work referred to in the paper has not been cited in the reference section. They should point out whether observations or arguments derived from other publications are accompanied by the respective source. Reviewers will notify the editor of 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 associated with the papers.
