Our editors and employees work hard to ensure the content we publish is ethically sound. To help us achieve that goal, we closely follow the advice laid out in the guidelines and flowcharts on the COPE (Committee on Publication Ethics) website.

A few key points:

• Any manuscript you submit to this journal should be original. That means it should not have been published before in its current, or similar, form.  If any substantial element of your paper has been previously published, you need to declare this to the journal editor upon submission. Please note, the journal editor may use Crossref Similarity Checkto check on the originality of submissions received.
• Your work should not have been submitted elsewhere and should not be under consideration by any other publication. The submitted work should be original and should not have been published elsewhere in any form or language (partially or in full), unless the new work concerns an expansion of previous work. (Please provide transparency on the re-use of material to avoid the concerns about text-recycling („self-plagiarism“).
• No data, text, or theories by others are presented as if they were the author’s own („plagiarism“). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks (to indicate words taken from another source) are used for verbatim copying of material, and permissions secured for material that is copyrighted. JCE use software to screen for plagiarism.
• Results should be presented clearly, honestly, and without fabrication, falsification or inappropriate data manipulation (including image based manipulation). Authors should adhere to discipline-specific rules for acquiring, selecting and processing data.
• If you have a conflict of interest, you must declare it upon submission; this allows the editor to decide how they would like to proceed.
• Authors are strongly advised to ensure the author group, the Corresponding Author, and the order of authors are all correct at submission. Adding and/or deleting authors during the revision stages is generally not permitted, but in some cases may be warranted. Reasons for changes in authorship should be explained in detail. Please note that changes to authorship cannot be made after acceptance of a manuscript.
• By submitting your work to JCE, you are guaranteeing that the work is not in infringement of any existing copyright.
