General information


GPPS expects authors to use the ICMJE’s criteria for authorship. All authors should meet these requirements, and all contributors who meet these requirements should be listed as authors. The criteria are:

  • Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
  • Drafting the work or revising it critically for important intellectual content; AND
  • Final approval of the version to be published; AND
  • Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

Contributors who do not meet all four criteria for authorship should be mentioned in the acknowledgments.

Submitting author's responsibilities

The submitting author is the publisher's primary contact before and after publication. He/she is responsible for liaising with the co-authors, for ensuring they meet the above authorship criteria, and for submitting their details, declarations of interest, funding sources, etc. accurately.

The submitting author is also responsible for making choices throughout the publication process, e.g., the review mode, on behalf of all authors, and for communicating these choices to all of the authors. The submitting author will also agree to our publishing agreement on behalf of all of the authors.

Redundant publications

GPPS journal will not consider studies that have already been published in peer-reviewed literature or that are under consideration for publication elsewhere.   We welcome the submission of manuscripts available on preprint repositories and of papers presented at conferences.

Research integrity and publishing ethics

GPPS journal adheres to the COPE recommendations and upholds the highest standards in publication ethics and research integrity. We do not tolerate data or figure manipulation, plagiarism, redundant publication, inaccurate or incomplete declarations of interest, or other irregularities. We will deal with allegations of misconduct following COPE’s guidelines, and issue corrections or retractions of articles as necessary. For further details see Wager E. & Kleinert S. (2011). Responsible research publication: international standards for authors, in: Mayer T. & Steneck N. (eds) Promoting Research Integrity in a Global Environment. Imperial College Press / World Scientific Publishing, Singapore (pp 309-16).

Data and material sharing

To promote the transparency and reproducibility of research, we request that, where applicable, authors make the data, method, or materials underlying their paper available to readers following the best practice in their discipline (e.g., through deposition in public repositories). Research data is commonly defined as “ data collected, observed or created, for analysis purposes to produce original research results.” Relevant DOI, accession, or reference numbers should be provided in the manuscript.

Third-party material

Authors who reproduce non-original material in their manuscript should ensure it is appropriately attributed to the original authors and sources. The rightsholder may have specific instructions on how to credit the source. If that material is under copyright, it can only be reproduced with the rights holder's permission. Authors are responsible for obtaining such permissions and will be required to provide them to the editorial office before publication.  

When requesting permission to reuse content, such as figures, tables, text, etc., the authors should make sure they clearly stipulate the intended use for that content. See our guidelines page or contact the editorial office for further guidance.

Declaration of competing interest

Authors must disclose any potential conflict of interest as part of the submission. A conflict of interest, or competing interest is anything that may, or may be perceived to, influence the authors’ work. Conflicts of interest typically stem from financial, personal, or professional relationships, but may have other sources as well. The declaration of interest is published with each article.

Editors and reviewers are also required to declare any competing interest that may influence their evaluation of the manuscript and, where appropriate, recuse themselves.


The acknowledgments will appear in a separate section at the end of the article before the declaration of interest and references. All contributors who do not meet the criteria for authorship should be listed in the acknowledgments section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support.

Disclosure of funding sources

All funding sources for the research submitted should be acknowledged separately from the declaration of interest and acknowledgment sections. The funding statement should contain, when applicable, the funding organization, grant number, and recipients and will be included in the published article.

Single-blind review

GPPS journal operates a single-blind review: reviewers are anonymous to the authors at all times.


Articles are published under the open-access model. Published articles are free to download, reuse and adapt under an appropriate Creative Commons license (see below).

Article processing charge

GPPS makes no charge for the processing of papers that have already been peer-reviewed and presented at a GPPS technical conference. For papers that have not been presented in this way, GPPS charges authors (or their institution or funding organisation) a fee (see here for current fees) for the processing of such papers. An invoice will be issued by GPPS after the accepted paper was typeset. Payment is a condition of publication.
