Data Availability and Reproducibility Policy of TJEB
1. General Principles
TJEB supports transparency, research integrity, and reproducibility in scholarly publishing. Authors are expected to provide sufficient information to allow readers, reviewers, and editors to understand the data, materials, methods, and analytical procedures that support the findings of a manuscript.
TJEB recognises that not all data can be shared publicly. Legal, ethical, confidentiality, privacy, commercial, contractual, or security restrictions may limit data sharing. In such cases, authors must clearly explain the restriction.
2. Data Availability Statement
Original research articles submitted to TJEB must include a Data Availability Statement. The statement must indicate:
- whether data were generated or analysed in the study;
- where the data can be accessed, where applicable;
- whether access is open, restricted, or available on reasonable request;
- any legal, ethical, confidentiality, privacy, contractual, or other restrictions;
- whether related code, materials, instruments, or supplementary files are available, where applicable.
The Data Availability Statement will be published with the article.
3. Repository Expectations
Where feasible, authors are encouraged to deposit datasets, code, and related research materials in a recognised, stable, and accessible repository that supports long-term access, citation, and preservation. Suitable repositories may include:
- institutional repositories;
- discipline-specific repositories;
- general-purpose repositories such as Zenodo, Harvard Dataverse, Open Science Framework (OSF), or Figshare;
- recognised national or international data repositories.
Repositories should, where possible, provide persistent identifiers such as a DOI or stable URL.
4. Restrictions and Exceptions
TJEB does not require authors to share data publicly where legitimate restrictions apply. Restrictions may include:
- personal or sensitive data;
- confidential business, institutional, or government data;
- data subject to legal or contractual limitations;
- data involving research participants, communities, organisations, or vulnerable groups;
- data where disclosure could cause harm or breach ethical obligations.
Where data cannot be shared, authors must explain the reason in the Data Availability Statement.
5. Code, Materials, and Supplementary Files
Where applicable, authors are encouraged to make available the code, models, questionnaires, interview guides, analytical scripts, survey instruments, or other materials needed to understand or reproduce the analysis. Such materials may be made available through:
- a recognised repository, preferably one that provides a DOI or stable URL;
- supplementary files submitted with the manuscript and published with the article, where technically possible;
- availability from the corresponding author upon reasonable request;
- restricted access arrangements where ethical, legal, confidentiality, privacy, contractual, or other limitations apply.
6. Citation of Datasets and Materials
Datasets, code, and other research materials used in the manuscript should be cited appropriately where they are publicly available. Where a dataset, code, or other research material has a DOI or other persistent identifier, it should be cited and included in the reference list and, where relevant, also mentioned in the Data Availability Statement.
7. Reproducibility Expectations
Authors should describe their methods, data sources, assumptions, analytical procedures, and limitations clearly enough to allow readers to understand how the findings were produced and to assess their reliability. For empirical studies, authors should provide sufficient information on:
- data sources;
- sample construction;
- variables and measurement;
- analytical methods;
- software or tools used, where relevant;
- limitations affecting reproducibility.
8. Editorial Assessment
TJEB may request additional information about data, code, materials, methods, or reproducibility where necessary for editorial assessment, peer review, or publication ethics purposes. Authors are expected to respond to such requests in a timely and transparent manner.
Failure to provide an adequate Data Availability Statement, or a reasonable explanation for restrictions on data, code, or materials, may result in a request for revision, delay in editorial processing, rejection of the manuscript, or other appropriate editorial action.
9. Relationship with Other Journal Policies
This policy should be read together with:
- Guide for Authors
- Publication Ethics and Malpractice Statement
- Research Ethics / Ethical Oversight Policy
- AI Use Policy for Authors, Reviewers and Editors
- Archiving and Preservation Policy
