Competing Interests

All authors must include a competing interest declaration in their title page. This declaration will be subject to editorial review and may be published in the article.

Competing interests are situations that could be perceived to exert an undue influence on the content or publication of an author’s work. They may include, but are not limited to, financial, professional, contractual or personal relationships or situations.

If the manuscript has multiple authors, the author submitting must include competing interest declarations relevant to all contributing authors. 

Example wording for a declaration is as follows: “Competing interests: Author 1 is employed at organisation A, Author 2 is on the Board of company B and is a member of organisation C. Author 3 has received grants from company D.” If no competing interests exist, the declaration should state “Competing interests: The author(s) declare none”. 

Authorship and contributorship

All authors listed on any papers submitted to this journal must be in agreement that the authors listed would all be considered authors according to disciplinary norms, and that no authors who would reasonably be considered an author have been excluded. For further details on this journal’s authorship policy, please see this journal's publishing ethics policies.

Author affiliations

Author affiliations should represent the institution(s) at which the research presented was conducted and/or supported and/or approved. For non-research content, any affiliations should represent the institution(s) with which each author is currently affiliated. 

For more information, please see our author affiliation policy and author affiliation FAQs.

English language editing services 

Authors, particularly those whose first language is not English, may wish to have their English-language manuscripts checked by a native speaker before submission. This step is optional, but may help to ensure that the academic content of the paper is fully understood by the Editor and any reviewers.  

In order to help prospective authors to prepare for submission and to reach their publication goals, Cambridge University Press offers a range of high-quality manuscript preparation services, including language editing. You can find out more on our language services page.

Please note that the use of any of these services is voluntary, and at the author's own expense. Use of these services does not guarantee that the manuscript will be accepted for publication, nor does it restrict the author to submitting to a Cambridge-published journal. 

Supplementary materials

Material that is not essential to understanding or supporting a manuscript, but which may nonetheless be relevant or interesting to readers, may be submitted as supplementary materials. Supplementary materials will be published online alongside your article, but will not be published in the pages of the journal. Types of supplementary materials may include, but are not limited to, appendices, additional tables or figures, datasets, videos, and sound files.

Supplementary materials will be published with the same metadata as your parent article, and are considered a formal part of the academic record, so cannot be retracted or modified other than via our article correction processes. Supplementary materials will not be typeset or copyedited, so should be supplied exactly as they are to appear online. Please make sure you are familiar with our detailed guidance on supplementary materials prior to submission.

Where relevant we encourage authors to publish additional qualitative or quantitative research outputs in an appropriate repository, and cite these in manuscripts.
