Publication Ethics and Publication Malpractice Statement
Duties of Editors
Fair play and editorial independence
Editors evaluate submitted manuscripts exclusively on the basis of their academic merit (importance, originality, study’s validity, clarity) and its relevance to the journal’s scope, without regard to the authors’ race, gender, sexual orientation, ethnic origin, citizenship, religious belief, political philosophy or institutional affiliation. Decisions to edit and publish are not determined by the policies of governments or any other agencies outside of the journal itself. The Handling and Managing Editors have full authority over the entire editorial content of the journal and the timing of publication of that content.
Editors and editorial staff will not disclose any information about a submitted manuscript to anyone other than the corresponding author, reviewers, potential reviewers, other editorial advisers, and the publisher, as appropriate.
Disclosure and conflicts of interest
Editors and editorial board members will not use unpublished information disclosed in a submitted manuscript for their own research purposes without the authors’ explicit written consent. Privileged information or ideas obtained by editors as a result of handling the manuscript will be kept confidential and not used for their personal advantage. Editors will recuse themselves from considering manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships/connections with any of the authors, companies or institutions connected to the papers; instead, they will ask another member of the editorial board to handle the manuscript.
The editors ensure that all submitted manuscripts being considered for publication undergo peer-review by at least one reviewer who is expert in the field, and aim for having two such reviewers. The Handling and Managing Editors are responsible for deciding which of the manuscripts submitted to the journal will be published, based on the validation of the work in question, its importance to researchers and readers, the reviewers’ comments, and such legal requirements as are currently in force regarding libel, copyright infringement and plagiarism. The co-executive directors may confer with other editors or reviewers in making this decision.
Involvement and cooperation in investigations
Editors will take responsive measures when ethical concerns are raised with regard to a submitted manuscript or published paper. Every reported act of unethical publishing behaviour will be looked into, even if it is discovered years after publication. If, on investigation, the ethical concern is well-founded, a correction, retraction, expression of concern or other note as may be relevant, will be published in the journal.
Duties of Reviewers
Contribution to editorial decisions
Peer review assists editors in making editorial decisions and, through editorial communications with authors, may assist authors in improving their manuscripts. Peer review is an essential component of formal scholarly communication and lies at the heart of scholarly endeavor.
Any invited referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should immediately notify the editors and decline the invitation to review so that alternative reviewers can be contacted.
Any manuscripts received for review are confidential documents and must be treated as such; they must not be shown to or discussed with others except if authorized by the Handling and Managing Editors (who would only do so under exceptional and specific circumstances). This applies also to invited reviewers who decline the review invitation.
Standards of objectivity
Reviews should be conducted objectively and observations formulated clearly with supporting arguments so that authors can use them for improving the manuscript. Personal criticism of the authors is inappropriate.
Acknowledgement of sources
Reviewers should identify relevant published work that has not been cited by the authors. Any statement that is an observation, derivation or argument that has been reported in previous publications should be accompanied by the relevant citation. A reviewer should also notify the editors of any substantial similarity or overlap between the manuscript under consideration and any other manuscript (published or unpublished) of which they have personal knowledge.
Disclosure and conflicts of interest
Any reviewer who has conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies or institutions connected to the manuscript and the work described therein should immediately notify the editors to declare their conflicts of interest and decline the invitation to review so that alternative reviewers can be contacted.
Unpublished material disclosed in a submitted manuscript must not be used in a reviewer’s own research without the express written consent of the authors. Privileged information or ideas obtained through peer review must be kept confidential and not used for the reviewer’s personal advantage. This applies also to invited reviewers who decline the review invitation.
Duties of Authors
Originality and plagiarism
Authors should ensure that they have written and that they submit only entirely original works, and if they have used the work and/or words of others, that this has been appropriately cited. Publications that have been influential in determining the nature of the work reported in the manuscript should also be cited. Plagiarism takes many forms, from "passing off" another's paper as the author's own, to copying or paraphrasing substantial parts of another's paper (without attribution), to claiming results from research conducted by others. Plagiarism in all its forms constitutes unethical publishing behaviour and is unacceptable.
Multiple, duplicate, redundant or concurrent submission/publication
Papers describing essentially the same research should not be published in more than one journal or primary publication. Hence, authors should not submit for consideration a manuscript that has already been published in another journal.
Articles previously published in Combinatorial Theory may be published elsewhere, as long as the author(s) acknowledge(s) that it was previously published in Combinatorial Theory, providing volume, issue, and page numbers.
Authorship of the manuscript
Only persons who meet these authorship criteria should be listed as authors in the manuscript as they must be able to take public responsibility for the content: (i) made significant contributions to the conception, design, execution, data acquisition, or analysis/interpretation of the study; and (ii) drafted the manuscript or revised it critically for important intellectual content; and (iii) have seen and approved the final version of the paper and agreed to its submission for publication. All persons who made substantial contributions to the work reported in the manuscript (such as technical help, writing and editing assistance, general support) should be acknowledged in the "Acknowledgements" section after their written permission to be named has been obtained. The corresponding author should ensure that all appropriate coauthors (according to the above definition) and no inappropriate coauthors are included in the author list and verify that all coauthors have seen and approved the final version of the manuscript and agreed to its submission for publication.
Disclosure and conflicts of interest
Authors should—at the earliest stage possible (generally by submitting a disclosure form at the time of submission and including a statement in the manuscript)—disclose any conflicts of interest that might be construed to influence the results or their interpretation in the manuscript. All sources of financial support for the work should be disclosed (including the grant number or other reference number if any).
Acknowledgement of sources
Authors should ensure that they have properly acknowledged the work of others, and they should also cite publications that have been influential in determining the nature of the reported work. Information obtained privately (from conversation, correspondence, or discussion with third parties) must not be used or reported without explicit, written permission from the source. 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 in these services.
Hazards and human or animal subjects
If the work involves the use of animals or human participants, the authors should ensure that all procedures were performed in compliance with relevant laws and institutional guidelines and that the appropriate institutional committee(s) has approved them; the manuscript should contain a statement to this effect. Authors should also include a statement in the manuscript that informed consent was obtained for experimentation with human participants. The privacy rights of human participants must always be observed.
Authors are obliged to participate in the peer review process and cooperate fully by responding promptly to editors’ requests for raw data, clarifications, and other questions. In the case of a first decision of "revisions necessary," authors should respond to the reviewers’ comments systematically, point by point, and in a timely manner, revising and re-submitting their manuscript to the journal by the deadline given.
Fundamental errors in published works
When authors discover significant errors or inaccuracies in their own published work, it is their obligation to promptly notify the journal’s editors or publisher and cooperate with them to either correct the paper in the form of an erratum or to retract the paper. If the editors learn from a third party that a published work contains a significant error or inaccuracy, then it is the authors’ obligation to promptly correct or retract the paper or provide evidence to the journal editors of the correctness of the paper.
Duties of the Publisher
Handling of unethical publishing behaviour
In cases where alleged or proven scholarly misconduct, fraudulent publication, or plagiarism is brought to the attention of eScholarship, eScholarship staff will consult with the editorial board, and the board will take all appropriate measures to clarify the situation and to amend the article in question. This includes the prompt publication of an erratum, clarification or, in the most severe case, the retraction of the affected work. eScholarship’s removal policy is available in the eScholarship help center.
Access to and preservation of journal content
Combinatorial Theory is an open access journal, which means it is made freely available to readers across the world. eScholarship will preserve and host the journal without charge to authors, editors, or readers, even if the partnership with the journal is dissolved and/or the journal ceases to publish. All content contributed to eScholarship is automatically submitted to California Digital Library’s Merritt service for long-term preservation and curation.
