Focus and Scope

 

International Journal of Population Studies (IJPS) is an open access, multidisciplinary journal that publishes high quality original research and timely reviews of recent advances and emerging issues in population processes; dynamics of fertility, mortality, and migration; and linkages with socioeconomic and environmental change across times, spaces, and cultures.

 

The journal aims to provide a platform for researchers worldwide to promote and share cutting-edge knowledge and advances in different areas of population research. Article formats include editorials, original research articles, review articles, letters to editors, commentaries, perspectives, reports, and book reviews that address demography and population-related issues. The journal also offers special issues arising from conferences and other meetings.

 

 

Section Policies

 

Original research article

 

Original research articles refer to exclusively unpublished peer-reviewed research papers in demography and related fields. Papers may cover a wide range of topics on demography, as well as on population with a focus on empirical research, theory, and methods. Research papers are evaluated according to the quality, relevance and topicality of the key research question and results in relation to the current state of research. The assessment of relevance and topicality does not exclusively focus on the specific discipline, but also considers the contribution to an interdisciplinary debate between population studies and its adjacent fields of research. It should include critical overviews of the state of research, review of relevant research approaches and available results as well as references to the respective research literature, commensurability of the underlying research concepts and the empirical methods and sources/statistics. All articles in this category should present new findings or discoveries in a subject area that have not been published elsewhere. Quantitative and qualitative approaches are equally appreciated.

 

This article type typically has 5 tables and/or figures in total, approximately 50 references, and up to 9,000 words (inclusive of Abstract and References).

Review article

 

Review articles are summarized descriptions of recent findings and significant developments about a particular subject area of research. Review articles should include critical assessments of novel technologies and evaluation of subject advancement, elucidate unresolved questions, encompass comparative analysis with a substantial coverage of previous works, and highlight future prospects.

 

This article type typically has 5 tables and/or figures in total, approximately 70 references, and up to 10,000 words (inclusive of Abstract and References).

 

Perspective article

 

Perspective articles are author’s personal opinion on a subject/topic. Unlike reviews, perspective articles may cover a more specific part of the field. However, these are still required to uphold the spirit of academia of being objective as well as aim to initiate or further discuss on novel experimental procedures in the field. Therefore, perspective articles will be peer-reviewed. Accepted articles may be solicited or unsolicited.

 

This article type typically has 3 tables and/or figures in total, approximately 40 references, and 7,000 words (inclusive of Abstract and References).

 

Report

 

Reports are documents that summarize the execution and results of a clinical case involving population construct or a collaborative research programme that is directly related to the advancement of population research. Submissions will be evaluated on a case-by-case basis and are usually solicited by the editors.

 

This article type typically has 1-3 tables and/or figures in total, approximately 20 references, and 3,000 words (inclusive of Abstract and References). In International Journal of Population Studies, the abstract of a report is unstructured and should be in the length of 100-150 words.

 

Commentary

 

A commentary presents an in-depth analysis of current issues in population studies. 

 

This article type typically has 3 tables and/or figures in total, approximately 50 references, and 4,000 words (inclusive of Abstract and References).

 

Letters

 

Letters contain comments from reader(s) about individual articles. These letters must be constructive and contribute to the development of individual articles published or the entire journal. Letters containing new ideas, supporting data, or data criticizing the article may be subjected to peer-review (determined on a case-by-case basis by the journal’s editorial team). Letters should be addressed to either the editors or the authors of a particular article published in International Journal of Population Studies. The authors of the original paper may be invited to respond to these with a letter of their own.

 

This article type typically has no more than 3 tables and/or figures in total, no more than 20 references, and 2,000 words (inclusive of References). No Abstract is required.

 

Editorial

 

An editorial refers to a concise commentary highlighting prominent topics presented in a particular issue. Alternatively, an editorial represents the official opinions of the editors of the journal or the special issue. 

 

An editorial piece should not exceed 1,000 words (inclusive of References). An Abstract is not required. Up to 2 figures or tables are allowed.

 

Book review

 

A book review can be a review of a single book (800-1,200 words) or an essay on multiple books on the same subject or multiple books from the same author (3,000 words). No figures or tables are allowed. A book review cannot have more than 5 references.

 

Erratum

 

An erratum is a notification of a significant error made by the editors that affects the scholarly record or the scientific integrity of a published article. An erratum is always accompanied by Publisher Correction of the error. The corrections will not be made directly in the already-published articles. Authors who notice an error in their published articles should contact the editors at editor.ijps@accscience.com.

 

All publisher-introduced changes will be highlighted to the author for proofreading before final publication of the erratum.

 

Corrigendum

 

A corrigendum is a notification of an important error made by the author(s) that affects the scholarly record or the scientific integrity of a published article. A corrigendum is always accompanied by Author Correction of the error. The corrections will not be made directly in the already-published articles.

 

If certain errors are found, author(s) should contact the editors at editor.ijps@accscience.com, who will evaluate the impact of the errors and decide on the appropriate course of action. The publication of any corrections to a paper is at the sole discretion of the editors.

Addendum

 

An addendum is a notification of additional information about a published article. An addendum will only be published if the editors decide that the additional information is essential to the reader’s understanding of a significant part of the published article. The additional information can be construed as description, information, details or data that aid the readers to better understand the published works and should not significantly or substantially alter the original ideas of the works.

 

Peer Review Process

 

Every International Journal of Population Studies will be pre-screened by the editors to ensure its adherence to the scope, policies and style of the journal prior to peer review. Author(s) may suggest up to 4 academically qualified reviewers for consideration per submission. Authors should insert the current contact details, including full name, email address and affiliation, of the reviewers, and state the reason(s) for recommendation in the cover letter. However, the editorial team strives to ensure that the peer review process is fair and unbiased; therefore, there is no guarantee that a recommended reviewer will be approached to perform the peer review. In addition, author(s) may indicate the name of individuals that should not be invited as peer reviewer and provide the reasons in the cover letter.

 

Editor-in-Chief will decide on the submissions that should be considered for publication, and assign reviewers from inside the editorial board or outside, depending on the topic, to initiate double-blind peer review. Based on the review reports and reviewers’ recommendations, Editor-in-Chief makes one of the following editorial decisions: accept, minor revision, major revision, and reject.

 

If the decision made necessitates minor revisions to the paper, author(s) should spend no more than 10 days to prepare and submit the revision file containing revised manuscript, title page and back matter, cover letter, and response/rebuttal letter. If the decision made necessitates major revisions to the paper, author(s) should spend no more than 28 days to prepare and submit the revision file. The revision file will be once again pre-screened by editor and subsequently reviewed by the assigned reviewers.

 

The peer review process is considered complete for a submission once it has been accepted for publication in International Journal of Population Studies. Only accepted papers will be arranged for copy-editing, typesetting and proofreading before being published online.

Open Access Policy

 

This journal provides immediate open access to its content on the principle of making research freely available to the public in support of a greater global exchange of knowledge.

 

Core Editorial Policies

 

Authors should read the “Author Guidelines” before making a submission, and make sure that the manuscripts are written in accordance with the style and specifications of International Journal of Population Studies.

 

All submissions to International Journal of Population Studies are subject to rigorous peer review. Prior to the peer review process, all manuscripts will be pre-screened for conformity with the theme and scope of the journal, significance of the work (and novelty for original research article), and language used.

 

All submissions, accessory files, article metadata and author metadata will be treated confidential. The manuscripts will only be disclosed to editorial staff, reviewers and editors who participate in the pre-screening, review, processing and preparation of the manuscript for publication.

 

A paper would not be considered for publication in International Journal of Population Studies if it has been published or is under consideration for publication in other journals. In the cover letter, authors must confirm and state that neither the manuscript nor any significant part of it is under consideration for publication elsewhere or has appeared elsewhere in a manner that could be construed as a prior or duplication of the same work. The authors are required to notify the editorial team if the findings and data in their submissions have been presented in conferences.

 

After acceptance, the editors reserve the rights to edit the work so that it is of publishing standards.

 

Publishing Ethics

 

International Journal of Population Studies requests all members involved in the journal editing and publishing process to adhere to the Core Practices on publication ethics and follow the guidelines on handling publishing ethics allegations stipulated by Committee on Publication Ethics (COPE) 

 

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

 

The journal editors take all possible misconducts seriously. The editors, authors or readers can forward their concerns to the journal if they find out that the description in a submission or a published article may constitute an academic fraud, research misconduct or publication malpractice. The concerns or complaints on the possible allegations submitted to the journal will be dealt with promptly and appropriately. The complainant may direct all inquiries and correspondence to the Publisher at editor.ijps@accscience.com.

 

The editors do not approve of any plagiarism attempts. Duplication checker will be utilized at the editor’s discretion to verify the originality of submissions. A submission will be desk-rejected (during submissions stage) or rejected (during peer review stage) if the paper contains apparent and significant amount of plagiarized content. Therefore, authors are advised to adhere to the contemporary rules in academic writing and publishing ethics.

 

International Journal of Population Studies adopts a zero-tolerance policy concerning any academic misconducts and ethical violations in research and publication regardless of the severity of these issues. The violations include plagiarism, falsification of research, data fabrication, submitting manuscripts of others as one’s own, submitting same manuscript to different publication venues at the same time, and breached intellectual property rights. In cases of suspected misconduct and ethical violation, a panel will be formed to investigate the allegation. If the allegation is supported by evidence, the submitted manuscript in question will be declined for consideration in the journal and all authors will be informed in this regard. A retraction initiated by authors or by the journal is required to take place if the paper has already been published, and a retraction note will be published. Authors of the work in question will receive the Panel’s Decision via email and all appeals regarding the decision will have to be made to the Publisher at editor.ijps@accscience.com within 28 days of the decision date.

 

Preprint Policy

 

Authors are permitted to post their non-peer-reviewed original research manuscripts to any preprint servers before or in parallel with the formal submission to International Journal of Population Studies, as long as the preprint is not shared under any exclusive or restrictive license. During submission, authors are obliged to declare in the cover letter if the corresponding preprint version of their submission has been deposited on a preprint server, and provide any associated accession numbers or DOIs. Preprint versions that have been shared on a preprint server will not count as prior publication.

 

Authors are not allowed to post any versions of articles that have been revised after peer review, accepted for publication or published in the journal on a preprint server. A submission will not be considered by International Journal of Population Studies if its corresponding preprint version has been indexed.

 

International Journal of Population Studies reserves the right not to consider for publication or publish material that has been formally published in digital media that shall not be construed as preprint servers.

 

We encourage formal citation of preprints in the reference list, where appropriate.

 

Authorship and Author Information

 

Authorship should be limited to individuals who have contributed substantially to the work; for instance, conception or design of the work or the acquisition, analysis, or interpretation of data for the work. Authors must indicate their specific contributions to the published work under the “Author Contribution” section. The Author Contributions section must be presented in original research articles and review articles. Refer to the author contribution section of the Instructions for Authors  for more information.

 

Corresponding author(s) should be clearly indicated with asterisk (*) on the title page of every submission. We suggest no more than 2 corresponding authors per submission. A corresponding author is responsible for:

  • obtaining permission to submit and revise paper from all the authors mentioned in the manuscript,
  • ensuring adherence to all editorial and submission policies and for any communications and actions that may be necessary after publication, and
  • including written permission from the authors of the work concerned for any mention of any unpublished material included in the manuscript, e.g., data from manuscripts-in-press, personal communication, or work in preparation.

 

All authors should have a say in the final approval of the version to be published, in addition to reviewing the final manuscript prior to submission.

 

Authors that made equally significant contributions to the submitted work should be clearly indicated with superscript dagger symbols (†). The following footnote should be used for authors who have made equal contributions, and placed beneath the affiliation part:

“ †These authors contributed equally to this work.” The names of all equally contributing authors are preferably indicated together in the foremost part of the authorship list, and ideally, there should be no more than 2 equally contributing authors.

 

Accurate and complete author information, including full name, affiliation, email address, must be disclosed and provided during submission. Affiliations should contain the following core information: department, institution, city, state, postal code, and country.

 

Changes to Authorship

 

The Editorial Office of International Journal of Population Studies considers the authorship list is definitive by the time the submission is received. Thus, authors should check the list and order of authors before submitting their papers.

 

Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript is accepted for publication. The corresponding author should provide the valid reasons for the change in authorship list and the proof of written confirmation from all authors agreeing with such change (including the existing authors, author(s) to be added and/or removed) to the Editorial Office.

 

The requests for authorship changes need to be approved by the Editorial Office before any changes can be made.

 

If any requests to add, delete, or rearrange author names in the published article is granted following the finalized (online) publication of an accepted manuscript, the new changes will only be implemented in a correction (corrigendum or erratum).

 

Conflict of Interest

 

At the time of submission, authors must declare any (potential) conflicts or competing interests with any institutes, organizations or agencies that might influence the integrity of results or objective interpretation of their submitted works. Conflicts of interest can be divided into two categories: financial and non-financial.

 

Authors should declare financial conflict of interest based on the following aspects:

  • Author relation with the funding body and any potential conflicts of interest should be declared if the organization may gain or lose financially through the article publication. Disclosure should also include all sources of revenue paid (or promised to be paid) directly to authors or their institution on authors’ behalf over the 36 months before submission of the relevant work.
  • Any changes to the employment status of authors in any organizations, including resignation, current employment in another organization, and anticipated employment, should be declared if the organization may gain or lose financially through the article publication.
  • Ownership of stocks or shares by the authors in any organizations should be declared if author(s) may gain or lose financially through the article publication.
  • Receiving consultation fees or other forms of remuneration (including reimbursements for attending conferences) from organizations should be declared if the organization may gain or lose financially as a result of article publication.
  • Status of patents or patent applications (either awarded or pending) filed by the authors or their institutions should be declared if their value may be influenced by the article publication. Patent application number, patent applicant, name of inventor(s), application status, and specific aspect of paper covered by the patent application’s specification and/or claims should be disclosed.

 

Authors, reviewers and editors should declare any (potential) non-financial conflicts of interest and declare any unpaid roles or relations that may influence the decision on the article publication. This includes, but is not limited to, unpaid role in a government or non-governmental organization, unpaid role in an advocacy or lobbying organization, and unpaid advisory position in a commercial organization.

 

Authors who have nothing to declare are encouraged to add "No conflict of interest was reported by all authors" in this section of the paper. Failure to declare will result in a delay to editorial process and peer review progress. If necessary, the initial disclosure statement provided by the authors will be subject to edits for grammar corrections by the editors. Failure to comply with the conflict of interest disclosure statement requirement may result in rejection of the submissions.

 

In addition, reviewers and editors must disclose any association that poses a conflict of interest in connection with the manuscript. Examples of such activities could include personal or work-related relationships, events, etc. Reviewers must be aware of the peer-review policies, and proactively disclose all potential conflicts of interest, and guarantee that an article will be judged fairly and objectively.

Language

 

All submissions should ideally be written entirely in good American English. Submissions in good British English can be accepted as long as a mixture of spelling variants are not used in the submissions. Clarity and conciseness are critical requirements for publications; therefore, submissions that are not clearly written will be returned to authors. Authors are encouraged to employ the use of English editing service to polish and edit their papers so that they are submit-ready or publish-ready. The articles published in International Journal of Population Studies are in adherence with the publishable standards of academic and scientific writing.

Please note that utilizing a language editing service is not a guarantee of acceptance.

 

Anonymity and Privacy

 

Human subjects have a right to privacy that should not be violated without informed consent. Identifying information or identifiers, including names, initials, date of birth, contacts, medical record numbers, hospital numbers, and geographical location, should not be published in written descriptions, photographs, or pedigrees unless the information is essential for scientific purposes and the human subject (or parent or guardian) gives written informed consent for publication. Efforts must be made by the authors to at least mask or conceal any identifying information of the patients that appear in writing or within photograph.

 

Authors are obliged to explain to the human subject if revealing his/her identity cannot be fully avoided, e.g., an image of an identifiable body part like the face has to be published in the report. The relevant identifying information to be published, e.g., the image, must be shown to the subject, and consent for publication taken for the use of that information in the publication. If the subject dies, then consent must be obtained from next of kin or legal representative. Authors may consider using our sample Consent Form for Publication in International Journal of Population Studies. International Journal of Population Studies shall consider author version of consent form for publication if all the essential items as shown in our sample consent form were included.

 

All submissions will be checked for documentation of human subject consent for publication and for any potentially identifying information. Submissions that include identifying patient information without appropriate consent will not be considered for publication.

 

Policy Enforcement

 

All submissions describing human subject research will be preliminarily examined by journal editors to ensure that the specific requirements set out in the journal policies and guidelines are met. Submissions that do not meet the requirements may be rejected.

 

International Journal of Population Studies reserves the right to decline submissions that the editors believe the described works have not been conducted to the highest possible ethical standards, despite formal ethics approval has been obtained.

 

If ethical concerns arise or are discovered after publication, investigations will be organized. Any evidence pointing to substantial violations of ethical codes or oversight for the research may lead to a correction (e.g., erratum, corrigendum) or retraction of the paper. Authors’ institution, ethics committee or other appropriate body in relation to the potential ethical concerns may be contacted during the investigation.

* Ideally, all information given in the title page and back matter file, except for the manuscript title, should remain the same from the point of submission to paper acceptance. Thus, authors are responsible to ensure that all information therein is accurate before making submission. Refer to Authorship and Author Information section on About the Journal  for more information about International Journal of Population Studies’ authorship policy.

Submitting authors should refer to the relevant sections in the following for more detailed information.

 

Author metadata during submission

 

During the submission process, the submitting author must ensure that all particulars of author information, including full name, affiliation, and email address, are given in the author metadata column of the submission system. These particulars must exactly reflect those on the title page of the submission; this includes the author order of the authorship list. Provide authors’ ORCID ID, if available.

 

Article types

 

(1) Original research article

 

Original research articles refer to exclusively unpublished peer-reviewed research papers in demography and related fields. Papers may cover a wide range of topics on demography, as well as on population with a focus on empirical research, theory, and methods. Research papers are evaluated according to the quality, relevance and topicality of the key research question and results in relation to the current state of research. The assessment of relevance and topicality does not exclusively focus on the specific discipline, but also considers the contribution to an interdisciplinary debate between population studies and its adjacent fields of research. It should include critical overviews of the state of research, review of relevant research approaches and available results as well as references to the respective research literature, commensurability of the underlying research concepts and the empirical methods and sources/statistics. All articles in this category should present new findings or discoveries in a subject area that have not been published elsewhere. Quantitative and qualitative approaches are equally appreciated.

 

This article type typically has 5 tables and/or figures in total, approximately 50 references, and up to 9,000 words (inclusive of Abstract and References).

 

(2) Review article

 

Review articles are summarized descriptions of recent findings and significant developments about a particular subject area of research. Review articles should include critical assessments of novel technologies and evaluation of subject advancement, elucidate unresolved questions, encompass comparative analysis with a substantial coverage of previous works, and highlight future prospects.

 

This article type typically has 5 tables and/or figures in total, approximately 70 references, and up to 10,000 words (inclusive of Abstract and References).

 

(3) Perspective article

 

Perspective articles are author’s personal opinion on a subject/topic. Unlike reviews, perspective articles may cover a more specific part of the field. However, these are still required to uphold the spirit of academia of being objective as well as aim to initiate or further discuss on novel experimental procedures in the field. Therefore, perspective articles will be peer-reviewed. Accepted articles may be solicited or unsolicited.

 

This article type typically has 3 tables and/or figures in total, approximately 40 references, and 7,000 words (inclusive of Abstract and References).

 

(4) Report

 

Reports are documents that summarize the execution and results of a clinical case involving population construct or a collaborative research programme that is directly related to the advancement of population research. Submissions will be evaluated on a case-by-case basis and are usually solicited by the editors.

 

This article type typically has 1-3 tables and/or figures in total, approximately 20 references, and 3,000 words (inclusive of Abstract and References). In International Journal of Population Studies, the abstract of a report is unstructured and should be in the length of 100-150 words.

 

(5) Commentary

 

A commentary presents an in-depth analysis of current issues in population studies. 

 

This article type typically has 3 tables and/or figures in total, approximately 50 references, and 4,000 words (inclusive of Abstract and References).

 

(6) Letters

 

Letters contain comments from reader(s) about individual articles. These letters must be constructive and contribute to the development of individual articles published or the entire journal. Letters containing new ideas, supporting data, or data criticizing the article may be subjected to peer-review (determined on a case-by-case basis by the journal’s editorial team). Letters should be addressed to either the editors or the authors of a particular article published in International Journal of Population Studies. The authors of the original paper may be invited to respond to these with a letter of their own.

 

This article type typically has no more than 3 tables and/or figures in total, no more than 20 references, and 2,000 words (inclusive of References). No Abstract is required.

 

(7) Editorial

 

An editorial refers to a concise commentary highlighting prominent topics presented in a particular issue. Alternatively, an editorial represents the official opinions of the editors of the journal or the special issue. 

 

An editorial piece should not exceed 1,000 words (inclusive of References). An Abstract is not required. Up to 2 figures or tables are allowed.

 

(8) Book review

 

A book review can be a review of a single book (800-1,200 words) or an essay on multiple books on the same subject or multiple books from the same author (3,000 words). No figures or tables are allowed. A book review cannot have more than 5 references.

 

(9) Erratum

 

An erratum is a notification of a significant error made by the editors that affects the scholarly record or the scientific integrity of a published article. An erratum is always accompanied by Publisher Correction of the error. The corrections will not be made directly in the already-published articles. Authors who notice an error in their published articles should contact the editors at editor.ijps@accscience.com.

All publisher-introduced changes will be highlighted to the author for proofreading before final publication of the erratum.

 

(10) Corrigendum

 

A corrigendum is a notification of an important error made by the author(s) that affects the scholarly record or the scientific integrity of a published article. A corrigendum is always accompanied by Author Correction of the error. The corrections will not be made directly in the already-published articles.

 

If certain errors are found, author(s) should contact the editors at editor.ijps@accscience.com, who will evaluate the impact of the errors and decide on the appropriate course of action. The publication of any corrections to a paper is at the sole discretion of the editors.

Language

 

All submissions should ideally be written entirely in good American English. Submissions in good British English can be accepted as long as a mixture of spelling variants are not used in the submissions. Clarity and conciseness are critical requirements for publications; therefore, submissions that are not clearly written will be returned to authors. Authors are encouraged to employ the use of English editing service to polish and edit their papers so that they are submit-ready or publish-ready. The articles published in International Journal of Population Studies are in adherence with the publishable standards of academic and scientific writing.

Please note that utilizing a language editing service is not a guarantee of acceptance.

 

Letter capitalization

 

Use sentence case capitalization in all aspects of the submission. In sentence case, most major and minor words are lowercase (proper nouns, including name of organizations and name of guidelines, are an exception in that they are always capitalized for the first letter of each word, except for minor words, such as conjunctions and short prepositions). The first letter of the first word should always be uppercase.

 

Manuscript title

 

The title should capture the conceptual significance for a broad audience. The title should not be more than 50 words and should be able to give readers an overall view of the paper’s significance. Titles should avoid using uncommon jargons, abbreviations and punctuation.

 

Abstract

 

The purpose of abstract is to provide sufficient information and capture essential findings and/or messages of the paper. For full-length article, the length of an abstract should be in the range of 200-300 words. The abstract should be unstructured. Abstract is needed in original research article, review article, perspective article, report and commentary.

 

Keywords

 

Each submission should be accompanied by 3-6 keywords. Avoid using abbreviations and acronyms in keywords, unless they are established standard keywords. Separate keywords with semi-colons (i.e., term1; term2; term3).

 

Abbreviations and acronyms

 

Define abbreviations and acronyms upon their first appearance, separately, in the abstract, main text, table legends, and figure captions and legends.

 

Sections in article

 

(1) Section heading

 

Section headings should be in boldface. Examples of section headings of different levels are shown in the following:

Primary level : 1. Population of Indonesia

Secondary level : 1.3. High-dense communities

Tertiary level : 1.3.2. City planning in Jakarta

Authors are suggested NOT to introduce further sub-sections after the tertiary level section (e.g., 1.3.2.1. High-salt diet).

 

(2) Special sectioning requirements for an original research article

 

  • The introduction should provide a background that gives a broad readership an overall outlook of the field and the research performed. It identifies research problems and highlights the importance of the study. Introduction can conclude with a brief statement of the aim of the work and a comment about whether that aim was achieved.
  • Data and methods. This section provides a brief description on the method followed. The aim is to provide enough detail for other investigators to fully replicate the results. It is also required to facilitate better understanding of the results obtained. Protocols and procedures for new methods must be included in detail for the reproducibility of the experiments. Informed consent should be obtained from patients or parents prior to commencement of the study and should be mentioned in this section. Refer to the Anonymity and Privacy section of About the Journal for more information about obtaining consent. For research involving human subject, research ethics information, such as ethics approval identifiers and the name of Institutional Ethics Review Board or Institutional Review Board, should be indicated in this section.
  • This section focuses on the results from the analyses. After (statistical) analysis, all results, including tables and figures, must be neatly presented. If necessary, this section can be sub-divided into multiple topical sub-sections.
  • 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.
  • Use this section for interpretation only, and not to summarize information already presented in the text or abstract.

Data and image processing

 

Post-acquisition processing of images, photos and figures should be kept minimum to ensure that the final figures accurately reflect the original data as it was captured and/or produced. Any alterations should be applied to the entire image. Any kind of alteration, including but not limited to brightness, contrast and color balance, has to be clearly stated in the figure legend and in Materials and Methods section. For simulated or model figures, the software used for production, editing, and/or processing should be mentioned. Presenting images in the same figure must be made apparent and should be explicitly indicated in the appropriate figure legends.

 

Data comparisons should only be made from comparative experiments (or data from the same experiment). Same piece of data or figure should not be used in multiple instances, unless the images/data describe different aspects of the same experiment (reasons must be stated, wherever appropriate, in this regard). If inappropriate image/data manipulation is identified after publication, the editors reserve the right to ask for the original data and, if that is not satisfactory, to issue a correction or retract the paper, as appropriate.

 

Unit of measurements

 

Use SI units.

 

Figures

 

Include all figures, including photographs, scanned images, graphs, charts and schematic diagrams, on a separate sheet, together with tables. Avoid unnecessary decorative effects (e.g., 3D graphs) and minimize image processing (e.g., changes in brightness and contrast applied uniformly for the entire figure should be avoided or minimized). All images should be set against white background.

 

All figures should be numbered (e.g., Figure 1Figure 2) in boldface. Label all figures (e.g., axis, structures), and add caption (a brief title) and legend as a description of the illustration below each figure. Explain all symbols and abbreviations used. Each figure should have a brief title (also known as caption) that describes the entire figure without citing specific panels, followed by a legend, which is either the description of each panel or further description about the single image. Identify each panel with uppercase letters in parenthesis (e.g. (A), (B), (C), etc.) Figures must be cited in chronological manner in the text.

 

The preferred file formats for any separately submitted figure(s) are JPEG, PNG and TIFF. All figures should be of optimal resolution. Optimal resolutions preferred are 300 dots per inch (dpi) for RBG colored, 600 dpi for grayscale and 1,200 dpi for line art. Although there is no file-size limitation imposed, authors are highly encouraged to compress their figures to an ideal size without unduly affecting the legibility and resolution of figures.

 

If necessary, the editors may request author(s) to supply high-resolution and/or unprocessed images after submission or paper acceptance for pre-screening/review and production purposes, respectively.

 

Tables

 

Include all tables on a separate sheet, together with figures. Editable tables created using Microsoft Word are preferred. A table should be accompanied by a caption on top of it. Captions and legends (which are placed beneath table) should be concise. All tables should be numbered (e.g., Table 1Table 2) in boldface. Explain all symbols and abbreviations used. Tables must be cited in chronological manner in the text.

 

Lists and math formulae

 

Lists and math formulae should be properly aligned and included within the main body of the manuscript. List them using Roman numerals in parenthesis (e.g., I, II, III, IV, etc.) Lists and math formulae must be cited in chronological manner in the text.

 

Lists and math formulae should be given in editable text and not as images. Use the solidus (/) for small fractional terms, e.g., X/Y. In principle, variables should be italicized.

 

Footnotes and endnotes

 

Do not use footnotes and endnotes in manuscripts.

 

In-text citations

 

In-text citations should include the author’s surname and the year published. If the reference has no known year of publication, use ‘n.d.’ (without the quotation marks). The citation style depends on the number of authors for the reference.

 

 

In-text citation in a sentence

In-text citation in parentheses

One author

Dickson et al. (2014) brought up some points to support such an argument.

(Gu et al., 2012))

 

 

Do not include citations in the Abstract.

 

References

 

This section is compulsory and should be placed at the end of all manuscripts. Do not use footnotes or endnotes as a substitute for a reference list. The list of references should only include works that are cited in the text and that have been published or accepted for publication. Personal communications and unpublished works should be excluded from this section.

 

The references in reference list should be arranged in alphabetical order of the first author’s surname. Authors referenced should be listed with their surname followed by their initials. All references should also appear as an in-text citation. References for journal articles should follow the following pattern: Author(s) followed by year of publication, title of publication, full journal name in italics, volume number, issue number in parenthesis and, lastly, page range. For references with 6 or less authors, surnames and initials of authors must be provided, and ampersand (&) should be inserted before the name of the last author. For references more than 6 authors, surnames and initials for the first 6 authors should be provided in the reference list, and the rest of the authors can be styled as et al. If the DOI is available, please include it after the page range.

The revisions made should be described and/or clarified in the response/rebuttal letter; ideally, explanation about the revisions should be made clear with the help of page number and line number. If authors do not agree with reviewers’ comments and suggestions, rebut their points with strong evidence and reasonable arguments.

    Competing Interests

     

    Assigned reviewers should declare competing interests arising from dealing with and reviewing the assigned submission. Since we adopt double-blind peer review and assume that the author identity has been completely masked to the best of our effort, the most important question that could reasonably be perceived as interfering with your peer review of the manuscript is: Could you profit or be negatively impacted financially by the peer review of the assigned manuscript?

     

    If the reviewer’s answer to this question is “yes,” please immediately inform the handling editor.
