This ethical statement is based on COPE's Best Practice Guidelines for Journal Editors

Publication decision:  the editor is responsible for the decision of which manuscript to publish, the editor can be guided by the policies of the journal's editorial board and limited by the requirements that will apply regarding libel, copyright infringement, and plagiarism, the editor can confer with other editors or other reviewers in making this decision.
Fair play: an editor at all times evaluates a manuscript for intellectual content regardless of the author's race, gender, sexual orientation, religious beliefs, ethnic origin, nationality, or political philosophy.
Confidentiality: editors should not disclose any information about submitted manuscripts to anyone other than the appropriate authors, reviewers, potential reviewers, and publishers.
Disclosure and conflict of interest: material that is not published but disclosed in the submitted manuscript may not be used in the editor's own research without the written consent of the author.

Reviewer tasks 
Contribution to editorial decisions: peer review helps editors in making editorial decisions and through editorial communication with authors can also assist authors in improving the quality of the manuscript. 
Speed: any reviewer who is selected but feels ineligible to review the manuscript or knows that an immediate review is not possible, must notify the editor and withdraw from the review process. 
Standards of objectivity: reviews should be conducted objectively, personal criticism of authors is inappropriate, reviews should express their views clearly with supporting arguments. 
Acknowledgment of sources: the reviewer should identify relevant works that have not been cited by the author, any statement that the observations, derivations, or arguments have been previously reported should be accompanied by relevant citations. Reviewers should also call the editor's attention to any similarities in substance or overlap between the manuscript under consideration and other published manuscripts that they know personally. 
Disclosure and conflict of interest: privileged information or ideas obtained through peer review should be kept confidential and not used for personal gain. Reviewers should not consider manuscripts where they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with the author, company, or any institution related to the manuscript.

Author task 
Reporting standards: the original manuscript should present an accurate account of the work already done as well as an objective discussion of its significance. The underlying data must be accurately represented in the manuscript, a manuscript must contain enough detail and references to allow others to replicate the work. Deceptive or intentionally inaccurate statements are unethical and unacceptable behavior. 
Originality and plagiarism: authors must ensure that they have written entirely original work, and if the author uses someone else's work and/or words, then this is appropriately cited. 
Multiple or concurrent publications: an author may not publish essentially the same manuscript in more than one journal or have already published. Submitting the same manuscript to more than one journal simultaneously is unethical and unacceptable publishing behavior. 
Recognition of sources: proper recognition of the work of others should always be done, authors should cite publications referenced in submitted manuscripts. 
Manuscript author: authorship should be limited to those who have made a significant contribution to the conception, design, execution, or interpretation of the reported study. All persons who have made significant contributions must be listed as co-authors, where there are others who have participated in certain substantive aspects of the research project, they must be recognized or listed as contributors. 
Correspondence  authors must ensure that all co-authors are appropriate and that no co-authors are inappropriate to be included in the manuscript and that all authors have seen and approved the final version of the manuscript to be proposed in the publication submission. 
Disclosure and conflict of interest: all authors must disclose in their manuscript any financial or other substantive conflicts of interest that may be construed to affect the outcome or interpretation of their manuscript.
