Peer Review Process

To ensure high-quality publication, Asia Pacific Academy of Science Pte. Ltd. (APACSCI) conducts a stringent double-blind peer review process for all manuscripts submitted to its journals:

1. Upon submission, a manuscript is reviewed by the managing editor of the journal to assess for integrality and similarity. Once the manuscript has passed this pre-screening check, it will be passed to one of the academic editors (the Editor-in-Chief for a regular submission, or Editorial Board members. Whoever they are, the above-mentioned roles ensure to have no conflicts of interest).
2. The assigned academic editor carefully evaluates the manuscript to determine if its topic and content are suitable for consideration.
3. The assigned academic editor invites at least two independent-external reviewers who are suitably qualified to assess the paper. Authors can recommend reviewers or provide an avoidance list, and basic information for identifying and contacting the reviewers should be given. The recommended reviewers may not be invited upon the decision of the assigned academic editor.
4. Reviewers are asked to evaluate the manuscript's originality, methodology, contribution to the literature, presentation of results and support for the conclusion, and appropriate referencing of previous relevant studies.
5. According to the evaluation reports by the reviewers along with a review from the assigned academic editor, the Editor-in-Chief makes one of the following decisions: accept the submission, accept with minor revisions, accept with revisions required (major revisions), require resubmission for review, or decline the submission.
6. If the Editor-in-Chief suggests minor revisions, authors are given a maximum of 5 days to revise and resubmit the manuscript.
7. If the Editor-in-Chief suggests major revisions, authors are given a maximum of 14 days to revise and resubmit the manuscript.
8. After the re-submission of the revised manuscript, the above steps are repeated before the manuscript is accepted for publication.
9. Authors of rejected submissions have the right to make an appeal in writing to the editorial office of the specific journal (for AAS, editorial-vfc@apacsci.com) within 4 weeks of receiving the decision. The written appeal should include specific reasons for the appeal and point-by-point responses to the reviewers' comments.
10. Decisions made on appeals by the Editor-in-Chief are final and no further considerations will be made.

Editorial processes and decisions are not influenced by journal ownership, revenue streams, or advertising policies.

A corresponding author should be marked with "*", and the maximum of corresponding authors is two. A corresponding author serves as a representative of the authors and is responsible for contacting editors and reviewers, e.g., submitting manuscripts, responding to reviews, accepting queries, proofreading galleys, making corrections, etc. 

Changes to Authorship

Authorship changes (addition, deletion, or rearrangement of author names) should be made before the acceptance of the manuscript. Confirmation from all authors (including existing authors and author(s) to be added and/or removed) should be provided to the editorial office of the journal, together with the reason for such changes. Changes can be made after the approval of the journal. The publisher will deal with any changes or dispute over authorship following the COPE flowcharts of authorship and contributorship.

Conflict of Interest

Authors are required to declare any potential conflicts of interest (financial or non-financial) during the submission stage. Any agreements with study sponsors (for-profit or non-profit), such as those that interfere with the authors' access to the study's data or with the authors' ability to analyze or interpret the data and to publish manuscripts independently according to their own decision, should be avoided by authors at all costs.

APACSCI also requires reviewers and editors to declare any (potential) non-financial conflicts of interest and declare any unpaid roles or relations that may influence the decision on the manuscript's publication before acknowledging the assigned request. These include, but are not limited to, unpaid roles in a governmental or non-governmental organization, unpaid roles in an advocacy or lobbying organization, and unpaid advisory positions in a commercial organization.

In addition, reviewers and editors must disclose any association that poses a conflict of interest in connection with the manuscript, including but not limited to those interferes with, or could reasonably be perceived as interfering with, the full and objective presentation, peer review, editorial decision-making, or publication of research or non-research articles submitted to a journal. Examples are personal or work-related relationships with one of the authors or the reviewer is on the authors' avoidance list.

Plagiarism

Authors are advised to observe high standards in the aspect of publication ethics. Any plagiarism (fabrication or falsification of data) are strictly unacceptable practices in VFC, including duplicate publication of the author’s work without proper citation.

Every manuscript submitted for publication is checked for plagiarism via CrossCheck (powered by iThenticate) after submission and before being sent to the editor for editorial review. Any detection of overlapping and similar texts in the manuscripts submitted will be investigated promptly and may lead to the manuscript being rejected.

Language

The language of all manuscripts must be English (either British or American) and non-English words should be used sparingly. Poor English may lead to article rejection. Authors are encouraged to seek language polishing by a native English speaker or a professional editing service.

Withdrawal Policy

If the author decides to withdraw an article that has already been submitted to the journal, he/she would be required to pay a penalty fee. Authors are advised to keep in mind that an article should only be withdrawn if the authors detect significant error or flaws, as it is not an acceptable practice to withdraw an article after it has been sent for peer review.

3. Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals from the International Committee of Medical Journals Editors (ICMJE).

APACSCI is committed to protecting the privacy of its contributors and promises not to disclose personal information to third parties without permission, unless for necessary purposes of the publishing process or required by law.

Complaints and appeals

APACSCI takes allegations of misconduct (refer to the Misconduct Policy for more details) seriously and will launch an immediate investigation by a group of investigation members. Decisions will be made by the investigation group based on clear evidence, and the authors will be informed. If there is any appeal against the decision, it must be made to the publisher within 14 days of the decision date, or else actions will be taken after 14 days. The decision on the appeal is final.

Authors also could express complaints and concerns about delays, extensions, and unreasonable handling procedures during the editing process and the time it takes. The editor-in-chief will be accountable for initiating an investigation into the issue, and the complainant will receive feedback. Reasonable editing procedures will be enhanced.

Any complaints and appeals against APACSCI journals and editors can be directed to the publisher at editorial_office@apacsci.com, and APACSCI follows COPE guidelines in handling all complaints and appeals.

Research Involving Human Subjects

Authors who carry out research involving humans must declare that their studies followed the WMA Declaration of Helsinki. They must obtain approval from the concerned research ethics committee before carrying out the research and accept the monitoring by the committee. During the submission stage, authors are required to attach a statement containing the name of the ethics committee, the approval code, etc.

Informed consent to participate in the research must be obtained from all human subjects or their guardians. A statement on the consent to participate should also be included during submission. If there is no need for informed consent, authors must provide the name of the ethics committee and the reason for the absence of the need for informed consent.

Human subjects' right to privacy right is inviolable. Authors should not disclose any identifying information, including but not limited to names, initials, contacts, and medical record numbers, unless the absence of such information may influence the interpretation of the research. In addition, written informed consent for publication from the participants should be obtained. If participants are vulnerable, informed consent should be given by their guardians. Authors must inform the participants if pictures of their bodies (e.g., faces) have to be included in the manuscript and receive consent for publication. In the case of deceased human subjects, their next of kin or legal representative should be asked for consent.

Research Involving Animal Subjects

All studies involving animals should be approved by an ethics committee before the research is conducted. If ethical approval is not required by national laws, exemption from the ethics committee, the name of the ethics committee, and the reason should be provided by the authors during submission.

The following guidelines can be helpful for authors in upholding high ethical standards and avoiding submission rejection

• Code of Practice for the Housing and Care of Animals Used in Scientific Procedures
• ARRIVE Guidelines
• Three Rs
• Core Principles for the Care and Use of Animals in Research
• EU Regulations on Animal Research

APACSCI applies The ARRIVE Essential 10: Compliance Questionnaire for evaluating comparative experiments in living animals. Authors can also use it as a checklist.

Misconduct policy

Following COPE guidelines, APACSCI will not accept any misconduct behaviors that may mislead researchers.

Plagiarism

Plagiarism is not acceptable. Using the content from one's own previously published articles without proper citation is also considered plagiarism. APACSCI adopts Crossref Similarity Check (powered by iThenticate) for checking the originality of submissions. Manuscripts with a high similarity index may be rejected.

Fabrication and falsification

Fabrication and falsification of data or images will mislead researchers. APACSCI strongly opposes such practices and will reject suspicious submissions.

Duplicate submission

Duplicate submission of a manuscript that has been published or submitted to other journals at the same time will not be considered.

Manipulation

Peer review manipulation is expressly forbidden. In particular, peer review manipulation by editors involves ethical issues, and when detected or complained about, editors are dealt with seriously and are subject to dismissal.

Eliminate excessive manipulative citation included in the peer review process by reviewers. Reviewers are encouraged to suggest that authors add references that are necessary and constructive to the research. Reviewers' own articles that do not contribute to the scholarly content of the author's work must not be oversold for the sole purpose of inflating the number of citations to the reviewer's own article.

Authors are prohibited from over-citing their own previously published articles. The journal's editorial board will determine self-citation thresholds, which authors must strictly adhere to in order to eliminate any suspicion of citation manipulation.

Editors will be involved in the journal management process to detect citation manipulations from authors or reviewers.

As behaviors above are illegal academic and very unethical, the Publisher will deal with it seriously. If any misconduct action is verified, authors and their institutions will be informed, and all the journals of the Publisher will not receive any new submission from these authors and their institutions  in three years. If the allegations are disputable, their institutes are responsible to cooperate with the journal in investigating allegations.

If there are any suspicious allegations of the processing of articles especially the peer review process, referring to For Reviewers, the Editor-in-Chief will receive the complaint, and an investigation group will be formed to investigate the entire process, including the reviewers, editors, and staff who are involved. The journal will follow the procedures described in COPE and Publishing Ethics for handling allegations of misconduct.

Preprint policy

APACSCI allows authors to post preprints of the manuscript of their original research articles (limited to only this type of article) on community preprint servers, such as arXiv, bioRxiv, and PeerJ Preprint, prior to or simultaneous with their manuscript submission to APACSCI journals. Authors retain the copyright of the manuscript posted on a preprint server.

Authors should inform the editors of the preprint version of their submitted manuscript in a cover letter, as well as provide any associated accession numbers or DOIs. Revised versions per the result of the peer review process and accepted versions for publication should not be posted on a preprint server.

Upon publication of the article, APACSCI encourages authors to link the article in the preprint server to the journal site, so as to guide readers to access and refer to the final version of the article.

Correction, Retraction and Withdrawal

Correction

Authors are responsible for approving the final version of their manuscript and they should avoid any errors prior to publishing. In the case of errors that occur in a published article and have no influence on research results, APACSCI will issue a correction/erratum.

Authors, readers, and editors are encouraged to report any errors found in published papers. Please contact the editorial office of the particular journal.

Retraction

Based on COPE guidelines, the following conditions can lead to the retraction of a published article:

• Unreliable findings
• Plagiarism
• Published elsewhere without proper attribution to previous sources, disclosure to the editor, permission to republish, or justification
• Containing material or data without the authorization for use
• Infringement of copyright, violation of privacy, or other legal issues
• Unethical research
• Dubious peer review processes
• Failing to disclose a major competing interest

If any of the above misconduct proved to be true, a retraction notice will be issued with the reason, while the PDF of the retracted article will be watermarked with "Retracted". The journal editors will inform the authors of the retraction.

Paid Article Processing Charges will not be refunded to the authors if retraction occurs.

Withdrawal

Although not encouraged, authors can initiate the withdrawal of their submission before and during the peer review process by providing the reason. However, authors should note that a penalty fee of US$200 will be imposed for the withdrawal of a submission undergoing the peer review process due to the spent efforts on the evaluation of the manuscript by the editors and reviewers. Upon the approval of submission withdrawal, the submission will be removed from the journal's operation system, and the authors be informed.

Accepted articles and articles in press may also be withdrawn due to infringements of professional ethical codes (similar reasons to those for retraction).

Special Issue Policy

1. What is a Special Issue?

A Special Issue Program has been launched by Asia Pacific Academy of Science Pte. Ltd. A Special Issue is a collection of research hotspots or topics in a specific field. Guest Editors who are experts in this discipline, have the responsibility to drive the special issue program. Manuscripts accepted will both be ordered/archived in a regular volume/issue and a special issue.

Benefits of Special Issue

• Being more quickly discovered and cited.
• Promoting academic exchanges in this field.
• Avoiding repetition of topics.
• Disseminating the latest achievements.
• Broadening the visibility and maximizing the impact of a certain field so that more experts could focus on the topic.

Benefits of being Guest Editors

• Expanding the popularity.
• Initiating the communication and establishing co-operatives ties faster.
• Learning the latest research.
• Publishing one article without any APCs as the privilege.

2. How to drive a Special Issue?

There are two ways to obtain a special issue proposal.

• Guest Editors will be invited by assistant editors to submit a professional proposal.
• Authors and readers are welcomed to submit proposals via emailing to editorial-vfc@apacsci.com, and EiC will evaluate them for the viability and suitability for this journal.

Preparation for a proposal

A great topic is the crucial element for success. Each candidate topic will be selected by EiC for considering whether it is consistent with the scope of this journal. Hot topics are usually considered to be more attractive.

A proposal should include necessary information:

• List of Guest Editors
• Types of manuscript
• Main topics
• Submission deadline
• Keywords

3. Special Issue Ethics

APACSCI abides to the Code of Conduct of the Committee on Publication Ethics (COPE) and Best Practice Guidelines in all the editorial process. Each new submission must follow the journal's Editorial Policies, and any potential unethical manuscripts will not be passed to the nest stage. APACSCI promises to protect the confidentiality of all submissions unless the publishing needs. All the editors and reviewers must strictly abide by the Conflict of Interest of the journal, and they are asked to inform the Editorial Office if any potential conflicts of interest exist, and then, the Editorial Office may consider to change the editor or reviewer. As authors, they have the right to provide a list of avoided experts. Please appeal to editorial-vfc@apacsci.com for any requests related to manuscript promotion.

4. Workflow of a Special Issue

Manuscripts should be submitted to Open Journal Systems (OJS) and go through a double-blinded peer-reviewed process (refer to Peer Review Policy).

AIGC Policy

For authors:

Researchers using an Artificial Intelligence Generated Content (AIGC)  tool/service to directly generate the manuscript text must provide clear disclosures and statements, otherwise it will be considered academic misconduct. The journal allows the use of an AIGC tool/service for text embellishment and automatic sorting of references, but does not recommend the use of the AIGC tool/service in the thinking and concluding sessions of human involvement such as data analysis and interpretation, opinion hypothesis and conclusions, and the AIGC tool/service cannot fulfill the role of a textual author. If any part of the manuscript was written using an AIGC tool/service, it must be described openly, transparently, and in detail in the Methods or Acknowledgments section, for example:

"In the preparation of this work, the authors used the [name of the specific AIGC tool/service] to [purpose of use: e.g., literature research/text embellishment, etc.]. After using this tool/service, the authors reviewed and edited the content as needed, and take full responsibility for the content of the publication."

For Reviewers:

Reviewers are required to disclose whether any artificial intelligence (AI) tools were utilized in the preparation of their review reports. This disclosure should be clearly indicated as a note within the reports themselves.

Units of Measurement

Value, Function, Cost adopts and follows the rules of International System of Units (SI) for physical quantities and units of measurement. For example:

• Quantities including time, length, mass, electric current, etc., should be written as s (second), m (metre), kg (kilogram), A (ampere) after metric numbers.
• Adopt unified format for the same unit of measurement.

Research Data Policy

According to the data and reproducibility of COPE, APACSCI encourages authors to share associated data, code, and materials, register clinical trials, and use standardized guidelines to achieve greater transparency, replicability, and trust in scientific findings. Thus, authors are encouraged to deposit datasets in a data repository; the premise is that this data is not suitable for submission as online supplementary files. Authors who have deposited raw data in community database repositories are encouraged to include a data availability statement in their manuscript. The statement should provide information about the availability of the research data and any limitations or conditions associated with accessing the data, except for reasonable controls related to human privacy or biosecurity. Reusing scientific data can offer great potential for further scientific and economic development.

• Data sharing

For data shared, the  FAIR Data Principles should be followed, which guides that (meta)data are assigned a globally unique and eternally persistent identifier. Authors should cite the correct sources. Collaborative practices should be implemented across journals and institutions to monitor and ensure the scientific validity and credibility of overall research practices. Authors are encouraged to prioritize the use of original data from their study and provide supporting data such as accessible data sources as early as possible.

Regarding data involving confidentiality/privacy/personal privacy, etc., authors are advised to do their best to hide identifiable sensitive information and to share data in strict accordance with mandatory guidelines for the discipline.

According to the guidelines of COPE regarding unpublished data, the journal will address concerns to the data provider regarding the scientific rigor of an unpublished dataset. The journal will contact the corresponding author, and request comments on the concerns, supporting documentation as needed, and information about any other affected content. Following the guidelines regarding published data, if there is a manuscript associated with a published dataset whose scientific rigor is in doubt, the journal will contact any implicated journals that have published results from the suspicious dataset, summarizing the issue and actions taken to date. Authors must respond with a satisfactory update. If the issues are major or impact the conclusions of the manuscript, the author(s) should withdraw the manuscript or the journal will reject the submission.

• Data citation

Authors are encouraged to cite any datasets deposited in external repositories mentioned in their manuscript in the references. For previously published datasets, authors should cite both the published research article and the source of the dataset itself. Journal editorial staff will check and enforce proper data citation before publication.

Data citations should include the minimum information recommended by DataCite:

1)      Author(s)

2)      Year of publication/release

3)      Title

4)      Publisher/repository or archive name

5)      Persistent identifier (e.g., DOI)

• Data repository

Authors are encouraged to deposit their datasets in the relevant community dataset repository, or a general dataset repository (including any generalist data repository provided by a university, funder or institution for its affiliated researchers) that aligns with the specifications and requirements of their discipline could be selected. The publisher recommends that authors select a repository with a DOI (Digital Object Identifier) to ensure that the referenced dataset can be linked to consistently.

Authors could explore online resources for lists of registered data repositories through FAIRsharing.org and re3data.org.

Here are some examples of generalized dataset repositories:

• Open Science Framework
• Dryad Digital Repository
• Figshare
• Harvard Dataverse
• Zenodo
• Science Data Bank
