Ethical standards for publication exist to ensure high-quality scientific publications, public trust in scientific findings, and that people receive credit for their work and ideas.
All manuscripts are subject to peer review and are expected to meet standards of academic excellence. If approved by the editor, submissions will be considered by peer reviewers, whose identities will remain anonymous to the authors.
Our Research Integrity team will occasionally seek advice outside standard peer review, for example, on submissions with serious ethical, security, biosecurity, or societal implications. We may consult experts and the academic editor before deciding on appropriate actions, including but not limited to recruiting reviewers with specific expertise, assessment by additional editors, and declining to further consider a submission.
Authors must not use the words, figures, or ideas of others without attribution. All sources must be cited at the point they are used, and reuse of wording must be limited and be attributed or quoted in the text.
Hindawi uses Crossref Similarity Check (iThenticate) and our own software to detect submissions that overlap with published and submitted manuscripts.
Manuscripts that are found to have been plagiarized from a manuscript by other authors, whether published or unpublished, will be rejected and the authors may incur sanctions. Any published articles may need to be corrected or retracted.
Duplicate submission and redundant publication
Hindawi journals consider only original content, i.e. articles that have not been previously published, including in a language other than English. Articles based on content previously made public only on a preprint server, institutional repository, or in a thesis will be considered.
Manuscripts submitted to Hindawi journals must not be submitted elsewhere while under consideration and must be withdrawn before being submitted elsewhere. Authors whose articles are found to have been simultaneously submitted elsewhere may incur sanctions.
If authors have used their own previously published work, or work that is currently under review, as the basis for a submitted manuscript, they must cite the previous articles and indicate how their submitted manuscript differs from their previous work. Reuse of the authors’ own words outside the Methods should be attributed or quoted in the text. Reuse of the authors’ own figures or substantial amounts of wording may require permission from the copyright holder and the authors are responsible for obtaining this.
Hindawi journals will consider extended versions of articles published at conferences provided this is declared in the cover letter, the previous version is clearly cited and discussed, there is significant new content, and any necessary permissions are obtained.
Redundant publication, the inappropriate division of study outcomes into more than one article (also known as salami slicing), may result in rejection or a request to merge submitted manuscripts, and the correction of published articles. Duplicate publication of the same, or a very similar, article may result in the retraction of the later article and the authors may incur sanctions.
Authors whose submitted manuscripts are found to include citations whose primary purpose is to increase the number of citations to a given author’s work, or to articles published in a particular journal, may incur sanctions.
Editors and reviewers must not ask authors to include references merely to increase citations to their own or an associate’s work, to the journal, or to another journal they are associated with.
Fabrication and falsification
The authors of submitted manuscripts or published articles that are found to have fabricated or falsified the results, including the manipulation of images, may incur sanctions, and published articles may be retracted.
Conflicts of interest
Conflicts of interest (COIs, also known as ‘competing interests’) occur when issues outside research could be reasonably perceived to affect the neutrality or objectivity of the work or its assessment. This can happen at any stage in the research cycle, including during the experimentation phase, while a manuscript is being written, or during the process of turning a manuscript into a published article. Potential conflicts of interest must be declared — whether or not they actually had an influence — to allow informed decisions. In most cases, this declaration will not stop work from being published nor will it always prevent someone from being involved in a review process.
If unsure, declare a potential interest or discuss with the editorial office. Undeclared interests may incur sanctions. Submissions with undeclared conflicts that are later revealed may be rejected. Published articles may need to be re-assessed, have a corrigendum published, or in serious cases be retracted. For more information on COIs, see the guidance from the ICMJE and WAME.
Conflicts of interest do not always stop work from being published or prevent someone from being involved in the review process. However, they must be declared. A clear declaration of all possible conflicts – whether they actually had an influence or not – allows others to make informed decisions about the work and its review process.
If conflicts of interest are found after publication, this may be embarrassing for the authors, the Editor and the journal. It may be necessary to publish a corrigendum or reassess the review process.
Conflicts include the following:
- Financial — funding and other payments, goods and services received or expected by the authors relating to the subject of the work or from an organization with an interest in the outcome of the work
- Affiliations — being employed by, on the advisory board for, or a member of an organization with an interest in the outcome of the work
- Intellectual property — patents or trademarks owned by someone or their organization
- Personal — friends, family, relationships, and other close personal connections
- Ideology — beliefs or activism, for example, political or religious, relevant to the work
- Academic — competitors or someone whose work is critiqued
Authors must declare all potential interests in a ‘Conflicts of interest’ section, which should explain why the interest may be a conflict. If there are none, the authors should state “The author(s) declare(s) that there are no conflicts of interest regarding the publication of this paper.” Submitting authors are responsible for coauthors declaring their interests.
Authors must declare current or recent funding (including article processing charges) and other payments, goods or services that might influence the work. All funding, whether a conflict or not, must be declared in the ‘Funding Statement’.
The involvement of anyone other than the authors who 1) has an interest in the outcome of the work; 2) is affiliated to an organization with such an interest; or 3) was employed or paid by a funder, in the commissioning, conception, planning, design, conduct, or analysis of the work, the preparation or editing of the manuscript, or the decision to publish must be declared.
Declared conflicts of interest will be considered by the editor and reviewers and included in the published article.
Editors and Reviewers
Editors and reviewers should decline to be involved with a submission when they
- Have a recent publication or current submission with any author
- Share or recently shared an affiliation with any author
- Collaborate or recently collaborated with any author
- Have a close personal connection to any author
- Have a financial interest in the subject of the work
- Feel unable to be objective
Reviewers must declare any remaining interests in the ‘Confidential’ section of the review form, which will be considered by the editor.
Editors and reviewers must declare if they have previously discussed the manuscript with the authors.
If Hindawi becomes aware of breaches of our publication ethics policies, whether or not the breach occurred in a journal published by Hindawi, the following sanctions may be applied across the Hindawi journals:
- Rejection of the manuscript and any other manuscripts submitted by the author(s).
- Not allowing submission for 1–3 years.
- Prohibition from acting as an editor or reviewer.
Hindawi may apply additional sanctions for severe ethical violations.
Suspected breaches of our publication ethics policies, either before and after publication, as well as concerns about research ethics, should be reported to our Research Integrity team, overseen by the Head of Research Integrity.
Hindawi may ask the authors to provide the underlying data and images, consult editors, and contact institutions or employers to ask for an investigation or to raise concerns.
Corrections and retractions
When errors are identified in published articles, the publisher will consider what action is required and may consult the editors and the authors’ institution(s).
Errors by the authors may be corrected by a corrigendum and errors by the publisher by an erratum.
If there are errors that significantly affect the conclusions or there is evidence of misconduct, this may require retraction or an expression of concern following the COPE Retraction Guidelines.
All authors will be asked to agree to the content of the notice.
