Authors should submit a cover letter with their manuscript to support the publication request and outline each author's contributions. The letter should also declare potential competing interests, if any. If your article is part of a special issue, please also indicate this in your cover letter.
A competing interest exists when interpretation of data or presentation of information may be influenced by the author's personal or financial relationship with other people or organizations. Authors must disclose any financial and non-financial competing interests that may cause harm or embarrassment were they to become public after publication of the manuscript.
Authors will be required to complete and sign a declaration of competing interests. All competing interests that are declared will be listed at the end of published articles. Where an author gives no competing interests, the listing will read 'The author(s) declare that they have no competing interests'.
In order to give appropriate credit to each author, individual contributions to the manuscript should be specified in the cover letter accompanying the submitted manuscript. JHEOR complies with the recognized ethical standards for publications and authorship, including Section II “Ethical Considerations in the Conduct and Reporting of Research” of the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, established by the International Committee of Medical Journal Editors (http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html).
An 'author' is generally considered to be someone who has made substantive intellectual contributions to a published study. To qualify as an author one should have:
1) Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
2) Drafting the work or revising it critically for important intellectual content; AND
3) Final approval of the version to be published; AND
4) Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. Acquisition of funding, collection of data, or general supervision of the research group, alone, does not justify authorship.
To identify each author's contributions in the cover letter accompanying the submitted manuscript, the following format including author's initials should be used: AB carried out the molecular genetic studies, participated in the sequence alignment and drafted the manuscript. CD carried out the immunoassays. EF participated in the sequence alignment. GH participated in the design of the study and performed the statistical analysis. IJ conceived of the study, and participated in its design and coordination and helped to draft the manuscript. All authors read and approved the final manuscript.
Manuscript contributors who do not meet the criteria for authorship should be listed in the acknowledgement section. Examples of those who should be acknowledged persons who provided purely technical help, writing and/or editing assistance, or a department chair who provided only general support.
In addition, please acknowledge anyone who contributed to the article's conception, design, acquisition of data, or analysis and interpretation of data, or who was involved in drafting the manuscript or revising it critically for important intellectual content, but who does not meet the criteria for authorship. Please also include the source(s) of funding for each author, and for the manuscript preparation.
Authors must describe the role of the funding body, if any, in design, in the collection, analysis, and interpretation of data; in the writing of the manuscript; and in the decision to submit the manuscript for publication. Please also acknowledge anyone who contributed materials essential for the study. If a language editor has made significant revision of the manuscript, we recommend that you acknowledge the editor by name, where possible. Please note that authors should obtain permission to acknowledge from all those mentioned in the acknowledgements section.
