Focus and Scope

For Authors

• Publishing Ethics

  APACSCI upholds the spirit of strict adherence to high ethical standards. This is consistent with APACSCI's mission of publishing high-quality articles and promoting open scientific exchanges globally. APACSCI follows the Ethical Oversight Guidelines of the Committee on Publication Ethics (COPE) in overseeing the publication process, as well as the activities of APACSCI journals, editors, and reviewers.

  
  

  APACSCI and all the editors adhere to the following guidelines:

  
  

  1. Core Practices of the Committee on Publication Ethics (COPE);

  
  

  2. Principles of Transparency and Best Practice in Scholarly Publishing developed by the Committee on Publication Ethics (COPE), Directory of Open Access Journals (DOAJ), Open Access Scholarly Publishers Association (OASPA), and World Association of Medical Editors (WAME).

  
  

  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.

• Editorial Policies

  Authors should read the "Author Guidelines" before making a submission, and make sure that the manuscripts were written in accordance to the style and specifications of the journal's policy.

  
  

  All manuscripts submitted to Metaverse are subject to rigorous peer review. Prior to the peer review process, the manuscripts will be screened for acceptable English language, novelty and relevance to the Focus and Scope of the journal.

  
  

  Any manuscripts submitted to Metaverse will be treated as confidential materials. The manuscripts will not be disclosed to anyone except individuals such as editorial staff, reviewers and editors who participate in the initial screening, review, processing and preparation of the manuscript for publication (if accepted).

  
  

  A manuscript would not be accepted if it has been published or is currently under consideration for publication in any other journals. The authors are required to notify the editorial team if the findings and data in their submissions have been presented in conferences.

• 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.

• 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.

• 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).

• 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.

• 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.

• Authorship

  Based on the guidelines of the International Committee of Medical Journal Editors (ICMJE), authorship should be limited to those who meet the following four criteria:

  
  

  
  
  1. Contributed substantially to the conception or design of the manuscript or the acquisition, analysis, or interpretation of data for the manuscript; AND
  
  
  2. Drafted the manuscript or reviewed it critically for significant intellectual content; AND
  
  
  3. Have final approval of the version to be published; AND
  
  
  4. Agreed to be responsible for the manuscript in ensuring that problems relating to the accuracy or completeness of any part of the manuscript are appropriately investigated and resolved.
  
  

  
  

  Individuals who do not meet the above four criteria should not be listed as authors but should be acknowledged. All authors are expected to make meaningful contributions to this work. The publisher strictly prohibits false authorships, including those obtained through purchase, and only recognizes genuine contributions. Authors should disclose whether artificial intelligence (AI)-assisted technologies were used in the preparation of their manuscripts and how they used them. Authors should also report the use of AI for writing assistance in the Acknowledgment section. AI tools should not be used in sections that rely on human intellectual analysis, such as data interpretation and conclusion summarization. 

  
  

  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's guidance on authorship and contributorship.

• Article Processing Charges (APCs)

  APACSCI's publishing model is open access. Open access enables readers to freely access and download articles immediately after publication online. APACSCI charges authors article processing charges (APCs) so as to cover operation costs, such as those arising from the evaluation and production processes. APCs should be paid upon the acceptance of articles and ahead of publication.

  
  

  APC is USD 500. 

  
  

  Waiver and Discount Policy

  
  

  APACSCI believes there should be no barriers to the dissemination of knowledge, and thus APACSCI offers APC waivers and discounts to authors from low-income countries and authors with special circumstances. Authors should write to the editorial office of the specific journal to apply for waivers and discounts. The decision to approve such applications is made by the editorial office on a case-by-case basis. Publishing fees or waiver status should not influence editorial decision making.

  
  

   

  
  

  Note: APC is free for the submissions before December 2025.

  
  

   

  
  

   

• Indexing & Archiving

  
  
  • All the articles published online will be archived in Portico for long-term digital preservation.
  
  

  
  

  
  
  • Authors are encouraged to self-archive the final version of their published articles into institutional repositories (such as those listed in the Directory of Open Access Repositories).
  
  

  
  

  
  
  • Authors are also encouraged to use the final PDF version published on the website of Metaverse.
  
  

  
  

  Metaverse has been indexed and archived in Scopus, J-Gate, ROAD, EuroPub, ResearchGate, National Library Board of Singapore, Scilit, GoogleScholar, Crossref, and the journal aims to be included in the first-class academic databases in the world, such as WoS, Inspec, and EI.

• AI Policy

  For authors:

  
  

  Researchers using an Artificial Intelligence (AI) 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 AI tool/service for text embellishment and automatic sorting of references, but does not recommend the use of the AI tool/service in the thinking and concluding sessions of human involvement such as data analysis and interpretation, opinion hypothesis and conclusions, and the AI tool/service cannot fulfill the role of a textual author. If any part of the manuscript was written using an AI 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 AI 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

  Metaverse 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:

  Text

  The text of manuscripts should be in MS Word format. Original research articles should include the Introduction, Materials and Methods, Results, Discussion, and Conclusion (optional) sections.

  Section Headings

  Headings are used to indicate the hierarchy of the sections of the text. No more than three levels of headings should be employed. The first level of heading should be numbered as 1., 2., 3., 4. in boldface. Likewise, the second and third levels of headings should also be in boldface, for example, 1.1., 1.2., 1.1.1., 1.1.2.

  Introduction

  The introduction should provide a background that gives the broad readership an overall outlook on the field and the research performed. It pinpoints a problem and states the significance of the study. The introduction can conclude with a brief statement on the aim of the work and a comment about whether that aim was achieved.

  Materials and Methods

  This section provides the general experimental design and methodologies used. The aim is to provide enough details for other investigators to fully replicate the experiments. It is also to facilitate a better understanding of the results obtained.

  Results

  This section can be divided into subheadings. This section focuses on the results of the experiments performed.

  Discussion

  This section should provide the significance of the results and identify the impact of the research in a broader context. It should not be redundant or similar to the content of the Results section.

  Figures and Tables

  Figures (photographs, images, graphs, charts, and schematic diagrams) and tables should be referred to within the main text and numbered consecutively as Figure 1, Figure 2, Table 1, Table 2, etc. They should be placed as close as possible to where they are first cited and center-aligned. Both figure captions and table captions should be center-aligned, with figure captions set underneath the figures and table captions above the tables. When captions are longer than one line, they should be left-aligned.

  Figures can contain multiple panels. They should be numbered by Latin letters with parentheses, e.g., (a), (b), (c), or (A), (B), (C), placed below the image or within the image.

  Tables should be in MS Word/Excel table format. Tables containing too much information can be provided as supplementary material.

  In the main text, all figures and tables should be cited, e.g., "Table 1 indicates…", "Figures 1 and 2 shows…", and "Figure 1a,b shows…".

  The submission of images should comply with the following requirements to ensure clarity and readability for both reviewers and readers:

  • File Formats and Resolution: Images should be submitted in preferred formats such as PNG, JPG, SVG, with a resolution exceeding 300 dpi. Vector formats (e.g., SVG) are preferred for scalable images like graphs and line drawings. For line drawings, a higher resolution is necessary compared to photographic images, as each line must be rendered with precision.
  • Aesthetic and Technical Quality: Images should not only be aesthetically pleasing but also possess appropriate brightness and contrast levels to guarantee clarity.
  • Abbreviation: Any abbreviations or symbols utilized in the figures must be clearly defined in their respective legends (except for those already mentioned in this article).

  Note: Failure to provide images in the specified format and resolution may significantly compromise image quality and readability. If an individual image is excessively large, it may lead to slow loading or system timeouts. It is advisable that the PDF file for each article remains under 10 MB to enhance the reading experience for users.

   

  Lists and Equations

  Both bulleted lists and numbered lists are acceptable (refer to the template). Equations should be center-aligned and equation numbers should be right-aligned. If cited in the text, equations should be labeled with numbers in parentheses, e.g., Equation (1).

  In-Text Citations

  All bibliographical references that make an important contribution to the article should be numbered according to the appearance order. When cited in the text, the number should be placed in square brackets, for example:

  • Negotiation research spans many disciplines [3,4].
  • This effect has been widely studied [1–5,7].

  Appendix (Optional)

  An appendix provides information supplementary to an article and is included at the end of the article after the References section and it should start on a new page. For one appendix, it is designated as "Appendix"; for more than one appendix, they are designated "Appendix A", "Appendix B", etc.

  An appendix should be cited in the main text. Tables, figures, and equations should be started with the prefix A (i.e., Figure A1, Figure A2, Table A1, etc.).

  Back Matter

  The sequence of back matter elements in an article is listed below. There is no numeral label for back matter headings. Some of these elements are optional.
