1. Data and reproducibility principles

  • methods, sources, instruments, analyses, and limitations must be reported sufficiently for scholarly assessment;
  • authors retain research records for a period appropriate to law, ethics approval, consent, institutional policy, and discipline;
  • data sharing is encouraged but never requires violation of privacy, consent, cultural restrictions, security, or law;
  • editors may request supporting data, instruments, coding frameworks, search strategies, analytic scripts, or raw images confidentially.

2. Data Availability Statement

Every research article must include one of the following, adapted accurately:

Open data: The data and supporting materials are available at [repository and persistent URL/DOI].
Controlled access: The data are available from the corresponding author upon reasonable request, subject to [ethical/privacy/legal] restrictions.
Restricted data: The data are not publicly available because [specific ethical, privacy, legal, cultural, security, or contractual reason].
No new data: No new dataset was generated or analysed for this article; the sources used are identified in the manuscript.

3. Study-specific transparency

Study type Supporting information expected
Quantitative Instrument, codebook, variable definitions, analysis decisions, software/version, and code where feasible.
Qualitative Interview/topic guide, sampling logic, coding framework, reflexivity, credibility procedures, and appropriate de-identified excerpts.
Systematic review Protocol/registration where available, databases, complete search dates and strings, screening decisions, flow diagram, appraisal, and included-study table.
Bibliometric Database, exact query, search date, export fields, deduplication/cleaning, software/version, parameters, and analysable dataset where licensing permits.
Textual/historical Corpus definition, provenance, inclusion logic, edition/archive details, and analytical framework.

4. Plagiarism and unacceptable reuse

  • verbatim copying without quotation and citation;
  • close or misleading paraphrase without adequate attribution;
  • appropriation of ideas, data, images, tables, instruments, translations, or structure;
  • self-plagiarism or redundant reuse that conceals earlier publication;
  • duplicate submission or publication;
  • citation of a secondary source as though the original had been consulted;
  • invented, altered, unverifiable, or materially misrepresented references.

5. Similarity screening and interpretation

Submissions may be screened with Turnitin or another appropriate tool before or during review. A similarity percentage is not a finding of plagiarism and must not be interpreted mechanically.

Editors assess the source, amount, location, attribution, type of matched material, disciplinary conventions, prior dissemination, and effect on originality. Proper quotations, references, standard methodological phrases, preprints, and an author's disclosed thesis require contextual assessment.

Threshold clarification. A numerical similarity threshold may be used for triage, but it never guarantees acceptance below the threshold or proves misconduct above it.

6. Citation integrity

  • authors must verify that every reference exists and supports the associated claim;
  • relevant primary and current literature should be used where available;
  • irrelevant citation padding, coercive citation, reciprocal arrangements, and citation cartels are prohibited;
  • reviewers and editors must not request citations primarily to benefit themselves, the journal, or associated publications;
  • retracted works must not be used as valid evidence unless the retraction is itself being analysed and clearly identified.

7. Editorial response

Minor attribution or reporting problems may be returned for correction. Material overlap, unreliable data, fabricated references, duplicate publication, or refusal to provide reasonable supporting evidence may lead to rejection or post-publication action.

Suspected misconduct is handled under the Publication Ethics and Corrections policies, with an opportunity for affected parties to respond.
