Peer Review Statement

TAJAS operates a strict double-blind peer review process for all articles to help the editor make informed decisions that will be communicated to authors, to improve the quality of the papers. During the double-blind review, anonymity is maintained for both the authors and reviewers.

The average review period is expected to last for two months. The process of publishing an article begins when the authors submit their manuscripts through the journal's online platform. The Editor-in-Chief (EiC) initially screens the manuscript to determine if it is suitable for the TAJAS. TAJAS publishes papers that report original and unpublished research results. The journal considers plagiarism a serious offense. The journal will follow COPE guideline in suspected cases of plagiarism. Therefore, all manuscripts considered for publication undergo plagiarism check before being assigned to a peer review process. The EiC assigns an eligible manuscript to an Assistant Editor who will follow up the remaining peer review steps and provide a recommendation or decision to the EiC. Based on the reviewer's comments and the Assistant Editor's final opinion, the EiC decides to accept the paper, accept it with revisions, ask for resubmission, or reject it. If accepted, an acceptance letter is sent to the author and the manuscript is sent to production.

If revisions are necessary, the authors are given the opportunity to update their manuscript and resubmit it for further evaluation. In the event of rejection, a rejection letter is sent and the manuscript is archived.

The next step is for the manuscript to be edited by the typesetting secretariate, who ensures the manuscript adheres to the correct referencing system and journal style and layout. Once this is complete, the secretariate formats the manuscript into an article, adding necessary links and preparing it in both PDF and HTML formats. The final step is for the galley proof to review the manuscript and confirm it is ready for publication after consulting the corresponding author. The review process involves multiple independent reviewers, none of whom are aware of each other's identities. If the decisions of two reviewers are not the same, the EiC will seek opinion of additional reviewers. The editorial team takes care to uphold the reviewers' objectivity and quality, and if there is any doubt about their objectivity, they will assign additional reviewers.

Ethical Principles

TAJAS, implements the publication principles stipulated and accepted by following organizations: Committee on Publication Ethics (COPE), Directory of Open Access Journals (DOAJ). Ethical standards for publication exist to ensure high-quality scientific publications, public confidence in scientific findings, and respect for people's opinions. The TAJAS expects the author(s), reviewers and editors to comply with the principles of ethical rules throughout the publication period of the article.

Plagiarism

TAJAS undertakes to publish studies that have not been published elsewhere and/or are not under review elsewhere. Articles found to be plagiarized will be subject to plagiarism sanctions. In addition, the plagiarism control of the articles will be checked using TURNITIN, which is subscribed by Sokoine University of Agriculture. Threshold Similarity rate of manuscripts is 30%. Studies with a similarity rate of more than 30% are returned to the author for revision without being reviewed.

Duplicate Submission

Articles found to be published/under evaluation elsewhere will be subject to duplicate publication sanctions. When authors use their work to be published as the basis for their previous publications, they must both refer to their previous work and state that the submitted work presents new contributions that differ from the previous one.

Citation Manipulation

In order to increase the number of citations, citation sanctions will be applied to the submitted article when the existence of citations to a particular author's work or to articles published in a particular journal is detected.

Data Fabrication and Falsification

Data fabrication and falsification sanctions will be applied to articles in which experimental result fabrication and image manipulation are detected.

Improper Author Contribution
