Peer Review Process

JDTL is a peer-reviewed journal. All research articles undergo an initial editorial screening to assess their relevance to the journal’s scope, their scholarly quality, their compliance with the journal’s guidelines, and basic ethical and formal requirements.

Manuscripts that pass this initial screening are sent for double-anonymous peer review to at least two reviewers selected from among the members of the Scientific Commitee with appropriate subject expertise. Reviewers are selected by the editorial team on the basis of expertise, absence of conflicts of interest, and availability.

In double-anonymous peer review, the identities of authors and reviewers are concealed from each other throughout the review process.

The editorial team makes the final decision on acceptance, revision, or rejection on the basis of the reviewers’ reports and the journal’s editorial standards.

Publication Frequency

JDTL publishes two issues per year and follows a continuous publication model within each issue. Special issues may also be published when appropriate.
