The following statement of ethical standards applies to all authors, reviewers and editors of scientific papers that are published in JJAP and APEX.

Research Results

Source material of experiments and research results should be recorded and retained for a reasonable time after publication, in a manner that allows analysis and review by other scientists. Exceptions may be appropriate to preserve privacy or to assure patent protection.

Fabrication or falsification of data or reporting intentionally selective data to mislead or deceive the readers is a serious departure from professional conduct. Authors should strive not to allow mispresentation of their data, and not to include other’s data or research results without permission from the original authors or publishers. Plagiarism is a serious breach of ethics and is defined as the substantial replication, without attribution, of significant elements of another article already published by others or by themselves. Explicit acknowledgement should always be given when another work, by others or by themselves, is used in an article.

In case an error is discovered in a published or submitted article, the authors are obliged to make a prompt correction, by publishing an erratum or retraction of the article with approval by all the authors of the article published or submitted.

Authorship

All individuals who have made significant scientific contributions to the research work should be given the opportunity to be included as coauthors. Other persons who have contributed to the study should be acknowledged, but not identified as coauthors. The sources of financial support for the research project should be disclosed.

Every coauthor should be aware of the content of an article to be submitted, agree to its submission, and share appropriate responsibility for the work. Any individual unable to take appropriate responsibility for the article should not be included as a coauthor.

Duplicate submission is the most common ethics violation encountered. It is unethical for authors to publish articles describing essentially the same research result in more than one journal. It is also unacceptable for authors to submit the same manuscript concurrently to more than one journal.

Authors are requested to read the policy on “Submission of original JJAP papers based on contents already published in conference proceedings, extended abstracts, or the likes” carefully before paper submission.

Peer Review

Peer review provides advice to the editors concerning the publication of research results, and this is an essential step of the scientific publication process. Although reviewing manuscripts is time-consuming and sometimes difficult to pursue, all scientists have on obligation to do their fair share of reviewing.

Reviewers’ names are kept confidential and may only be disclosed to journal editors, who are also obliged to maintain confidentiality. All ideas and information that have been obtained during the review process must be kept strictly confidential and not used for competitive advantage.

Reviewers should give unbiased, objective assessment to all manuscripts offered for publication. Reviewers should disclose to the editorial office any potential conflicts of interest due to direct competitive or collaborative relationships with an author(s), and avoid cases in which such conflicts preclude an objective reviewing.

Comments made by reviewers may be seen by the authors. Reviewers should refrain from subjective personalized criticism of the authors. Reviewers’ comments should be given in a way where by authors can understand the basis of the comments and judgments, so that they can be used by the authors to improve the scientific quality of the article.

Reviewers are expected to provide relevant references that have not been cited in the article. They should also call the journal editors’ attention to any substantial similarity between the manuscript and any paper already published or being submitted elsewhere.

Conflict of Interest

All authors are requested to inform the editorial office of any potential conflicts of interest in advance of submitting an article (e.g., employment, stock ownership, patent licenses, etc). Similarly, all reviewers are requested to inform the editorial office of any potential conflicts of interest in advance of reviewing an article (e.g., being a collaborator of one of the authors, etc.). When it is recognized that objectivity and fairness cannot be ensured, the activity should be avoided or discontinued.

Submission of original JJAP papers based on contents already published in conference proceedings, extended abstracts, or the likes

A. Regular Paper Submission to JJAP

We welcome authors to submit extended versions of their conference proceedings papers, extended abstracts, or the likes already published (or accepted for publication at the time of submission) to JJAP as a full-length paper, i.e., a Regular Paper of JJAP. In such a case, however, the authors must follow the guidelines given below:

1. Please cite the corresponding conference proceedings papers or extended abstracts etc. in the manuscript and include a brief description in the text about what has been newly added in the present manuscript.

2. In order for the submission to be regarded as an original contribution, at least one of the following must be included as new material in the manuscript:

  • New data that were not disclosed in the already published articles.
  • More comprehensive explanation of the basic theory and/or detailed derivation of formulas and equations.
  • More comprehensive analysis of the data and/or more in-depth considerations or new interpretations of the results.

Simply adding more sentences and brushing up expressions in the original articles are not sufficient. Inclusion of new materials is mandatory.

The acceptance/rejection of the paper will be determined by evaluating whether the paper including the new materials has sufficient originality, novelty, and impact deserving its publication in JJAP provided that the content of the paper has already been published partially.

3. When submitting the manuscript, please attach copies of the preceding publications and explain in “Cover Letter to the Editor” what new materials have been included in the manuscript as compared with the already published articles.

They will be considered in the review process. Failure to submit appropriate copies at the time of submission might lead to the recognition of the manuscript as a “duplicate submission.” If the paper is judged to be a “duplicate submission” after having been accepted and published, the paper will be retracted.

Materials such as abstracts, records of presentations, technical digest papers, and the likes that satisfy the following conditions are excluded from the application of guidelines given above:

  • Materials were not subject to review and/or selection processes.
  • Materials were distributed only among the attendees of the meetings and pre- registered recipients of the meeting materials.

B. Submission of Brief Notes or Rapid Communications to JJAP

For submission of Brief Notes and Rapid Communications, the same guidelines given for Regular Papers will basically apply. However, for Rapid Communications, the authors are requested to clearly explain why “the letter-speed publication” is necessary while the main contents of the paper are already published (or will be published in advance).
