Publication standards
Authors of original research should present an accurate description of the theoretical and experimental background, followed by methodology specifics and results as well as an objective discussion of the significance of the work.

Authorship should be limited to those who meet the following criteria: (1) have made a significant contribution to the conception, design or execution of the reported research and/or (2) authored the manuscript or revised it critically. Others who made substantial contributions to the research reported, such as technical help, writing and editing assistance, general support, but who do not meet the criteria for authorship should not be listed as authors, but should be acknowledged. The corresponding author should ensure that all appropriate coauthors and no inappropriate ones are included in the paper, and that all coauthors have seen and approved the final version of the paper and have agreed to its submission for publication.

Originality and plagiarism
Authors should ensure that they have written and submitted only entirely original works, and if they have used the work and/or words of others, then these works must be cited and/or acknowledged appropriately. Publications that have been influential in determining the nature of the work reported in the manuscript should also be cited. Plagiarism may take many forms, from copying or paraphrasing substantial parts of another’s paper, to claiming results from research conducted by others. Plagiarism in any form constitutes unethical publishing behaviour and is strictly unacceptable.

Hazards and human or animal subjects
Submitted manuscripts research reports involving human or animal subjects, with potentially hazardous methods or procedures, should be in accordance with the Declaration of Helsinki guidelines. Privacy rights of human participants should always be upheld.

Authors should ensure that they have properly acknowledged the contribution of others, and should also cite publications that have been influential in determining the nature of the reported work. Authors should not use information obtained in the course of providing confidential services, such as refereeing manuscripts or grant applications, unless they have obtained the explicit written permission of the author(s) of the work involved. Funds and/or scholarships or any economic support in relation to the reported research should also be explicitly stated.
