IJAE upholds the highest standards regarding research and publishing practice. This comprehensive suite of policies covers the main responsibilities of the journal’s authors, reviewers, editors and publisher.
Submission to the journal implies that all authors have read and approved the manuscript, have agreed to its submission, and have the right to publish their work.
Submission to the journal also implies that all authors have read and complied with the journal’s policies on publication ethics. Authors of submitted manuscripts acknowledge that the journal’s editors reserve the right to reject or retract any manuscript that they believe may breach any of these policies. The authors take full responsibility for the contents of published articles.
The date the manuscript arrives at JSAE shall be deemed to be the date of receipt.
Submission to the journal implies that the manuscript has not been previously published (in part or in whole, in any language), is not in press, and is not under consideration for publication elsewhere.
Authors must inform the editors if any related manuscripts are under consideration, in press or published elsewhere. If in any doubt, authors should include the material distributed in other formats during the submission process. The availability of a manuscript on a publicly accessible preprint server does not constitute prior publication (see ‘Preprints’).
If authors choose to submit their manuscript elsewhere before a final decision has been made on its suitability for publication in IJAE they should first withdraw it from the journal.
Submission to the journal implies that the manuscript is original work. The journal may use software to screen manuscripts for unoriginal content. By submitting a manuscript to the journal, authors agree to this screening. Any manuscript with an unacceptable level of unoriginal material may be rejected or retracted at the editors’ discretion.
To support the wide dissemination of research, the journal encourages authors to post their research manuscripts on community-recognized preprint servers, either before or alongside submission to the journal. This policy applies only to the original version of a manuscript that describes primary research. Any version of a manuscript that has been revised in response to reviewers’ comments, accepted for publication or published in the journal should not be posted on a preprint server. Instead, forward links to the published manuscript may be posted on the preprint server.
When assessing the novelty of a manuscript submitted to the journal, the editors will not be influenced by other manuscripts that are posted on community-recognized preprint servers after the date of submission to IJAE (or after the date of posting on a preprint server, if the manuscript is submitted to the journal within four months).
Submission to the journal implies that all authors have seen and approved the author list. Changes to the author list after manuscript submission – such as the insertion or removal of author names, or a rearrangement of author order – must be approved by all authors and the editor.
Authors are encouraged to consider the Council of Science Editors (CSE) principles governing authorship. According to the CSE guidelines, authors have made substantial contributions to the work; have agreed to be held accountable for their own contributions to the work; can identify which co-authors are responsible for other parts of the work; have confidence in the integrity of the work; and have reviewed and approved the final manuscript. Contributors who do not qualify for authorship may be included in the Acknowledgements section instead.
Authors may digitally manipulate or process images, but only if the adjustments are kept to a minimum, are applied to the entire image, meet community standards, and are clearly described in the manuscript. All images in a manuscript must accurately reflect the original data on which they are based. Authors must not move, remove, add or enhance individual parts of an image. The editors reserve the right to request original, unprocessed images from the authors. Failure to provide requested images may result in a manuscript being rejected or retracted.
Reproducing copyrighted material
If a manuscript includes material that is not under the authors’ own copyright, the authors must obtain permission from the copyright holder(s) to reproduce it.
If a manuscript includes previously published material, the authors must obtain permission from the copyright owners and the publisher of the original work to reproduce it. The authors must cite the original work in their manuscript.
Availability of data and materials
Authors must disclose the source of publicly available data and materials, such as public repositories or commercial manufacturers, by including accession numbers or company details in their manuscript, as appropriate.
Authors may make their own data and materials available in Supplementary Material, or by linking from their manuscript to relevant community-recognized public databases or digital repositories. All data sets must be made available in full to the editors and reviewers during the peer review process, and must be made publicly available by the date of publication. Authors commit to preserving their data sets for at least three years from the date of publication in the journal.
The journal encourages authors to grant reasonable requests from colleagues to share any data, materials and experimental protocols described in their manuscript.
Authors of manuscripts describing experiments involving humans or materials derived from humans must demonstrate that the work was carried out in accordance with the principles embodied in the Declaration of Helsinki, its revisions, and any guidelines approved by the authors’ institutions. Where relevant, the authors must include a statement in their manuscript that describes the procedures for obtaining informed consent from participants regarding participation in the research and publication of the research.
Authors of manuscripts describing experiments involving animals or materials derived from animals must demonstrate that the work was carried out in accordance with the guidelines approved by the authors’ institution(s).
Conflicts of interest
In the interests of transparency, the journal requires all authors to declare any conflicts of interest in relation to their submitted manuscript. A conflict of interest exists when there are actual, perceived or potential circumstances that could influence an author’s ability to conduct or report research impartially. Potential conflicts include (but are not limited to) competing commercial or financial interests, commercial affiliations, consulting roles, or ownership of stock or equity.
Authors should list all funding sources for their work in the Acknowledgements section of their manuscript.
The journal maintains the confidentiality of all unpublished manuscripts. By submitting their manuscript to the journal, the authors warrant that they will keep all correspondence about their manuscript (from the Editorial Office, editors and reviewers) strictly confidential.
Editorial and peer review process
The journal uses single-blind peer review.
When a manuscript is submitted to the journal, it is assigned to the Editor-in-Chief, who performs initial screening. Manuscripts that do not fit the journal’s scope or are not deemed suitable for publication are rejected without review. The remaining manuscripts are assigned to an Associate Editor who assigns two reviewers to assess each manuscript. Reviewers are selected based on their expertise, reputation and previous experience as peer reviewers. The deadline for submission of the reviewers’ reports varies by article type.
Upon receipt of the two reviewers’ reports, the Associate Editor makes the first decision on the manuscript. If the reviewers’ reports offer contradictory advice, an Associate Editor can assign a third reviewer to aid the decision-making process. If the decision is to request revision of the manuscript, authors have 2 months to resubmit their revised manuscript. Revised manuscripts submitted after this deadline may be treated as new submissions.
The Associate Editor may send revised manuscripts to peer reviewers for their feedback or may use his or her own judgement to assess how closely the authors have followed the Associate Editor’s and the reviewers’ comments on the original manuscript. The Associate Editor then makes a recommendation to the Editor-in-Chief on the manuscript’s suitability for publication. The Editor-in-Chief is responsible for making the final decision on each manuscript.
The members of the Advisory Editorial Board act in consultative roles, providing feedback as reviewers and making suggestions to improve the journal. In cases where the Editor-in-Chief is an author on a manuscript submitted to the journal, a member of the Editorial Board is responsible for managing the entire review process and assessing the manuscript’s suitability for publication.
If a manuscript satisfies the journal’s requirements and represents a valuable contribution to the published literature, the Editor may recommend acceptance for publication in the journal.
In brief, the acceptance criteria are that articles published in the journal:
- are within the subject area as outlined in the Aims and Scope
- contain novel analyses, modelling and results, on which the authors’ clear assertions are based (Reserch Papers and Technical Notes) or provide objective and balanced overviews regarding particular topics or fields based on a review of the literature (Review Articles).
- are scientifically, ethically, and otherwise rigorous, with no clear errors
- are of interest to our broad audience
- are well-constructed and written in clear English.
If a manuscript does not meet the journal’s requirements for acceptance, but it has a high probability of acceptance after minor or major revision, the Editor may ask the authors to revise it accordingly. Revised manuscripts must be submitted within two months, otherwise they will be treated as new submissions.
If a manuscript does not meet the journal’s requirements for acceptance or revision, the Editor may recommend rejection.
When submitting a manuscript to the journal, authors may suggest reviewers that they would like included in or excluded from the peer review process. The Editor may consider these suggestions but is under no obligation to follow them. The selection, invitation and assignment of peer reviewers is at the Editor’s sole discretion.
It is the journal’s policy to transmit reviewers’ comments to the authors in their original form. However, the journal reserves the right to edit reviewers’ comments, without consulting the reviewers, if they contain offensive language, confidential information or recommendations for publication.
The Society of Automotive Engineers of Japna (JSAE) has granted the journal’s Editorial Board complete and sole responsibility for all editorial decisions. The JSAE will not become involved in editorial decisions, except in cases of a fundamental breakdown of process.
Editorial decisions are based only on a manuscript’s scientific and scholarly merit and are kept completely separate from the journal’s other interests. The authors’ ability to pay any publication charges has no bearing on whether a manuscript is accepted for publication in the journal.
Authors who believe that an editorial decision has been made in error may lodge an appeal with the Editorial Office. Appeals are only considered if the authors provide detailed evidence of a misunderstanding or mistake by a reviewer or editor. Appeals are considered carefully by the Editor-in-Chief, whose decision is final.
The journal maintains the confidentiality of all unpublished manuscripts. Editors will not:
- disclose a reviewer’s identity unless the reviewer makes a reasonable request for such disclosure
- discuss the manuscript or its contents with anyone not directly involved with the manuscript or its peer review
- use any data or information from the manuscript in their own work or publications
- use information obtained from the peer review process to provide an advantage to themselves or anyone else, or to disadvantage any individual or organization.
Conflicts of interest
A conflict of interest exists when there are actual, perceived or potential circumstances that could influence an editor’s ability to act impartially when assessing a manuscript. Such circumstances might include having a personal or professional relationship with an author, working on the same topic or in direct competition with an author, or having a financial stake in the work or its publication.
Members of the journal’s Editorial Board undertake to declare any conflicts of interest when handling manuscripts. An editor who declares a conflict of interest is unassigned from the manuscript in question and is replaced by a new editor.
Errata and retractions
The journal recognizes the importance of maintaining the integrity of published literature.
A published article that contains an error may be corrected through the publication of an Erratum. Errata describe errors that significantly affect the scientific integrity of a publication, the reputation of the authors, or the journal itself. Authors who wish to correct a published article should contact the editor who handled their manuscript or the Editorial Office with full details of the error(s) and their requested changes. In cases where co-authors disagree over a correction, the Editor-in-Chief may consult the Editorial Board or external peer reviewers for advice. If a Correction is published, any dissenting authors will be noted in the text.
A published article that contains invalid or unreliable results or conclusions, has been published elsewhere, or has infringed codes of conduct (covering research or publication ethics) may be retracted. Individuals who believe that a published article should be retracted are encouraged to contact the journal’s Editorial Office with full details of their concerns. The Editor-in-Chief will investigate further and contact the authors of the published article for their response. In cases where co-authors disagree over a retraction, the Editor-in-Chief may consult the Editorial Board or external peer reviewers for advice. If a Retraction is published, any dissenting authors will be noted in the text.
The decision to publish Errata or Retractions is made at the sole discretion of the Editor-in-Chief.
Editors’ own publications in the journal
Any member of the journal’s Editorial Board who is an author on a submitted manuscript is automatically excluded from the peer review process. Within the journal’s online manuscript submission and tracking system, they will be able to see their manuscript as an author but not as an editor, thereby maintaining the confidentiality of peer review.
A manuscript authored by an editor of the journal will be subjected to the same high standards of peer review and editorial decision making as any manuscript submitted to the journal.
Responding to potential ethical breaches
The journal will respond to allegations of ethical breaches by following its own policies and, where possible, the guidelines of the Committee on Publication Ethics .
The person reporting the ethical breach must provide sufficient evidence in order for an investigation to be undertaken.
Once an ethical breach has been confirmed, the Editor-in-Chief makes a final decision based on the opinions of the journal’s editorial board .
All manuscripts must be submitted via the journal’s online submission system, ScholarOne: https://mc.manuscriptcentral.com/ijae.The original or revised manuscript text may be uploaded as a PDF or Microsoft Word file, but a Word file is required for the final manuscript text. Figures may be submitted separately in several other formats.
Authors must adhere to the guidelines and layout as described in the template file. Manuscripts should be prepared in Microsoft Word or other appropriate software.
Manuscripts should be written in clear, grammatically correct English. Authors whose native language is not English are strongly encouraged to have their manuscript checked by a native English speaker or by an editing service prior to submission. If a manuscript is not clear due to poor English, it may be rejected without undergoing peer review.
Each article type should have the following main sections: Introduction, main body (with sections as determined by the authors), Conclusion, References. Subheadings may be used for each section. For full details, please see the template.
The first page of each manuscript should contain: Title, Subtitle (if required), Authors’ full names, Affiliations, Key words, Received date (left blank) and Abstract. The affiliations should contain the name and full address (including telephone number, facsimile number, and e-mail address) of the corresponding author.
The title should describe the content of the article briefly but clearly and is important for search purposes by third-party services. Do not use abbreviations in the title, except those used generally in related fields.
An effective title:
- conveys the main topics of the study
- highlights the importance of the research
- is concise
- attracts readers
Provide the full names, with initials, of the author(s). Use a superscript footnote number with a right parenthesis to indicate each author’s place of employment. See details for affiliations above.
Keywords must be chosen carefully. They should represent the content of your manuscript and be specific to your field or sub-field. A maximum of six keywords should be provided.
Units and Abbreviations
International System of Units (SI) should be used. Each abbreviation should be defined in parentheses together with its non-abbreviated term when it first appears in the text (except in the Title and Abstract).
The Abstract should clearly express the basic content of the paper in a single paragraph and should include the problem addressed, experimental approach, main results and findings, and conclusions. Abstracts must not exceed 250 words for all manuscript types. Avoid using specific abbreviations.
The Introduction should provide sufficient background information to allow the reader to understand the purpose of the investigation and its relationship with other research in related fields, although it should not include an extensive review of the literature.
The Conclusion should be concise and should deal with the interpretation of the results. Novel models or hypotheses may be proposed in this section only if they are suggested by the results obtained in the experiments. Do not repeat the description of the experimental results in this section.
This section should be brief. Authors should list all funding sources for their work in the Acknowledgements section.
References must be complete and checked at the source. In the main text, cite references in numerical order by order of citation, using superscript round brackets e.g. (1), (2, 3) , (4-7) etc. In the References section, list the surnames and initials of all authors in the author list. If available, all online publications should include the Digital Object Identifier (DOI). For articles with 1 to 6 authors, list all authors. For articles with more than 6 authors, list the first 6 authors then add ‘et al.’
