JDER still is not a member of the Committee on Publication Ethics (COPE), but we are committed to implementing the principles of it. We're trying to be a member in the future but follows the guidelines of Committee on Publication Ethics (COPE), for information on this matter in publishing and ethical guidelines please visit COPE.
Please note that any submission that has data collected from human subjects requires ethics approval. In this case, a clear statement to this effect must be made in any submitted manuscript presenting such research, specifying that the free and informed consent of the subjects was obtained. If your manuscript does not include ethics approval, your article will not be sent out for review. For qualitative articles it is mandatory that the following general principles be considered when submitting your manuscript.
Details of formal ethical approval should be stated at the end of method. If authors were not required to obtain ethical approval (as is the case in some countries) or unable to obtain attain ethical approval (as sometimes occurs in resource-poor settings) they should explain this. Please anonymize this information as appropriate in the manuscript, and give the information when asked during submission.
Procedures for securing informed consent should be provided.

Authorship Criteria and Contributions

This Journal also follows the guidelines mentioned in the Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals issued by the International Committee of Medical Journal Editors (ICMJE) (http://www.icmje.org). Each author should meet all criteria (1- 4) that recommended by the ICMJE, as following conditions:
Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND 

Drafting the work or revising it critically for important intellectual content; AND Final approval of the version to be published; AND 

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 be accountable for the parts of the work he or she has done. In addition, each author should be able to identify which coauthors are responsible for specific other parts of the work and should have confidence in the integrity of the contributions of any coauthors.

The authors also must certify that the manuscript represents valid data and has not been published in any form and is not being submitted for in the form of scientific presentations for publication elsewhere.
If requested, authors should be prepared to provide the data and must cooperate fully in obtaining and providing the data on which the manuscript is based for examination by the editors or their assignees.

Changes to authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed. Only in exceptional circumstances will the Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editor considers the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editor will result in a corrigendum.

Plagiarism

Submission of a paper implies that it reports unpublished work and that it is not under consideration for publication elsewhere. If previously published tables, illustrations or text are to be included, then this should be clearly indicated in the manuscript and the copyright holder's permission must be obtained. Previously published material can be cited in a later review or commentary article, but it must be indicated using quotation marks if necessary.
Plagiarism of text from a previously published manuscript by the same or another author is a serious publication offence. Small amounts of text may be used, but only where the source of the material quoted is clearly acknowledged. Fraudulent data or data stolen from other authors is also unethical and will be treated accordingly. Any alleged offence is considered initially by the Editorial Team.

Conflicts of interest

According to ICMJE guidelines, a conflict of interest may exist when an author (or the author’s institution), reviewer or editor has personal or financial relationships that influence (bias) inappropriately his/her action (such relationships are also known as dual commitments, competing interests, or competing loyalties). These relationships vary from those with negligible potential to those with great potential to influence judgment, and not all relationships represent true conflict of interest. The potential for conflict of interest can exist whether or not an individual believes that the relationship affects his or her scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, and of science itself. However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion.
Authors must make sure that they have declared any actual or potential conflicts of interest in their manuscript when submitting their work (if any). The corresponding author is responsible for confirming with the co-authors whether they have any conflicts to be declared or not.

Misconduct

The Journal of Disaster and Emergency Research will follow the COPE guidelines to deal with cases of potential publication misconduct.

Retraction

 Based on the COPE guidelines, JDER will consider retracting a publication if:

• It has clear evidence that the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error).
• The findings have previously been published elsewhere without proper cross-referencing, permission or justification (i.e. cases of redundant publication) 
• It constitutes plagiarism.
• It reports unethical research.
