Editorial Governance & Standards

Editorial Independence

EP Journals Group maintains strict editorial independence in all publication decisions. Editorial decisions are based solely on the academic merit, originality, and scholarly contribution of submitted manuscripts. The organisation does not permit commercial or political considerations to influence editorial judgements. Editors act impartially and recuse themselves from decisions in which they have a conflict of interest. The publisher does not intervene in editorial decisions and respects the autonomy of journal editors in matters of content selection.

Editorial Board Structure

Each journal within the EP Journals Group portfolio is supported by an Editorial Board comprising scholars with demonstrated expertise in the relevant discipline. All board members are accorded equal standing and participate collectively in upholding the standards of their respective journals. The organisation does not employ hierarchical editorial structures that concentrate decision-making authority in a single individual. This approach ensures that editorial decisions benefit from diverse perspectives and collective scholarly judgement.

Peer Review Process

All manuscripts submitted to EP Journals Group publications undergo double-blind peer review. A minimum of two independent reviewers with relevant subject expertise evaluate each submission. Reviewers assess manuscripts for originality, methodological soundness, clarity of presentation, and contribution to the field. An editorial decision is typically sent within one to two weeks of submission. Reviewers are expected to provide fair, constructive, and timely assessments. The double-blind model ensures that neither authors nor reviewers are aware of each other's identities, promoting objectivity and impartiality in the evaluation process.

Publication Standards & Ethical Compliance

Publication Ethics

EP Journals Group follows the guidelines established by the Committee on Publication Ethics (COPE) and expects all authors, reviewers, and editors to adhere to these principles. Allegations of misconduct, including plagiarism, data fabrication, and duplicate submission, are investigated thoroughly and may result in manuscript rejection, article retraction, or other appropriate sanctions. The publisher maintains documented procedures for handling allegations of misconduct and follows COPE flowcharts for investigating and responding to such concerns.

Open Access Policy

All articles published by EP Journals Group are made available under open access terms immediately upon publication. Published content is freely accessible to readers worldwide without subscription or access fees. This approach supports the broad dissemination of research findings and aligns with the organisation's commitment to the democratisation of knowledge. Published articles are licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), which permits sharing, adaptation, and reuse with appropriate attribution to the original authors.

Transparency & Disclosure

Authors are required to disclose any potential conflicts of interest that may influence the interpretation or presentation of their research. Funding sources and sponsorships must be acknowledged in submitted manuscripts. EP Journals Group publishes transparent policies regarding article processing, review timelines, and any applicable publication fees. The organisation is committed to providing clear and accurate information about its publishing practices to all stakeholders.

Open Access & Licensing Framework

EP Journals Group operates on a fully open access model. All published articles are made freely available to readers immediately upon publication, with no embargo period or access restrictions. This approach is consistent with the Budapest Open Access Initiative and reflects the organisation's commitment to maximising the visibility, accessibility, and impact of scholarly research.

Authors retain copyright of their published work. Upon acceptance, authors grant EP Journals Group a non-exclusive licence to publish, distribute, and archive the article. Published articles are licensed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), which permits:

  • •Sharing and redistribution of the material in any medium or format
  • •Adaptation, remixing, transformation, and building upon the material
  • •Commercial and non-commercial use, provided appropriate credit is given

Authors are encouraged to deposit their published articles in institutional repositories, subject-specific archives, and personal academic websites to maximise dissemination.

Archiving & Digital Preservation

EP Journals Group is committed to the long-term preservation and accessibility of published scholarly content. The organisation employs multiple strategies to ensure that published articles remain permanently accessible to readers and researchers.

All published articles are assigned Digital Object Identifiers (DOIs) through CrossRef, providing permanent, stable links to published content. DOIs ensure that articles can be located and cited reliably, even if the journal's web address changes in the future. The organisation maintains redundant backups of all published content and works with digital preservation services to ensure long-term archival access.

Authors and institutions are encouraged to deposit copies of published articles in appropriate repositories as an additional preservation measure. The open access licensing terms employed by EP Journals Group facilitate such archival practices.
