The Journal of the Polytechnic of Rijeka is a peer-reviewed journal open for collaboration with scientists and experts in the field of natural, biotechnical, technical and social sciences. It publishes papers that are relevant for the scientific and professional public in different fields of economics, information and communication technologies, computing, traffic and transport technology, agronomy and applied mathematics.

Texts will be published in Croatian or English.

The manuscript is delivered together with the Application form, which includes the signing of the Copyright Statement, consent to submitting the paper to the reviewing procedure and Statement – consent for personal data collection, processing and sharing (if there is more than one author, every author has to sign the statement and consent).

When writing articles authors must pay special attention to the appropriate structuring of the text and its length which should be in line with the accepted standards of scientific methodology. The manuscript should not exceed 7000 words including abstracts, keywords, footnotes, tables, references, captions and appendices.

The Editorial Board accepts applications in a prescribed form (Application form contains even an extended summary from 250 to 500 words, written in the third person) and a manuscript (written using the Template). By signing the Copyright Statement in the Application Form the author confirms the originality of the paper and authorship. In order to avoid withdrawing the paper during the review process, by signing the Copyright Statement the author also asserts compliance with the review process.

All applications go through the assessment process carried out by the members of the Editorial Board (according to the subject area addressed), as well as by other experts who are not members of the Editorial Board in the case of specific content. The Editorial Board reviews the submitted manuscripts and decides on the further procedure as follows:

a) which manuscripts, in case it is necessary, will be returned to the author with suggestions, recommendations and comments with the scope of improving the primarily methodological presentation of research materials;

b) which manuscripts will go through the review process;

c) which manuscripts will be rejected since:

• the subject matter does not meet the required scientific or professional level;
• the author has already published an article on a similar topic;
• the subject matter does not meet the Journal criteria, particularly if the content is beyond the concept orientation of the Journal and does not meet the methodological standards that the Journal must comply with.

If an article is not accepted, the Editorial Board notifies the author. If the author has accepted comments and suggestions given in the assessment process and has improved the text according to the requests made, the manuscript is then sent to the review process (double-blind review).

Other contributions, such as: reviews of books, doctoral dissertations, international conferences and other scientific meetings/gatherings, do not go through the review process. The Editorial Board chooses and edits reviews they consider relevant for publication in the Journal and in line with the editing policy concept.

Reviews of books and other contributions should be written as a critical review and their length should not exceed 8 typed double-spaced pages.

The Editing Board reserves the right to return texts to authors which do not meet the guidelines criteria, or to fully adapt contributions to comply with the Journal editing rules. Authors have to comply with all the editing and other guidelines provided by the Editorial Board. Contributions should be written in standard language free of spelling and grammar mistakes. The authors are responsible for language editing. The final version of the positively evaluated paper must be proofread, and submitted together with the signed proofreading confirmation by professional proofreaders. Before the final publication of accepted articles, a test print will be sent to authors to proofread, and at this stage, only misprints will be corrected.

Editorial Board disclaims responsibility for language and printing errors.

If none of the authors speaks Croatian, the Editorial Board will provide a translation of the article summary (including the title and key words) into Croatian.

In order to maintain the highest level of publishing ethical standards the Editorial Board of the Journal of the Polytechnic of Rijeka follows the recommendations of the COPE Code of Conduct for Journal Editors (https://publicationethics.org/).

Review Process

All articles submitted for publication are reviewed by two anonymous and independent reviewers. The names of the authors will also be unknown to the reviewers. Reviewers evaluate the article following some already given criteria by filling in a reviewer evaluation form. If the reviewers find that the article does not meet international standards and the Journal criteria, the Editorial Board does not accept the article. If the reviewer gives a positive review the article can be categorized into one of the following categories: Original scientific paper, Preliminary communication, Review article, Conference paper, and Professional paper.

Reviewers should carefully follow the Guidelines for reviewers.

After the reviews have been completed the Editorial Board analyzes them. Reviewer's comments are sent to the author after both reviews are received. If necessary, the author needs to adjust his/her paper to the reviewer's demands.  In case it is necessary, the Editorial Board may ask the third reviewer for an opinion. After the author resubmits the paper, the Editorial Board verifies whether the article has been revised following the reviewers' comments and suggestions.

Only categorized papers given two positive reviews are published. After the review process has been completed and the articles changed and revised by the authors and the Editorial Board, the Editor-in-Chief proposes the sequence of the accepted articles in the table of contents.

The criteria for the order in which the articles will appear in the Journal are:

1. Categorization according to a level of scientific excellence;
2. If the reviewers have categorized the article in different categories, the Editor-in-Chief proposes the categorization in favour of the author, i.e. to a higher category;
3. The topicality of the theme, author and the Journal's field of interest in the case when articles have been assigned the same level of scientific excellence (category).

The review process is usually completed within two or three months and accepted articles are usually published within six months (that is, in May).
