General information to authors

The Proceedings of the Estonian Academy of Sciences is an open access journal that publishes internationally peer reviewed primary research and review papers in the fields of sciences represented at the Estonian Academy of Sciences (mathematics, physics, chemistry, cosmology, industrial engineering etc.). The manuscripts submitted should be written in English and meet the following requirements.

It is essential that the paper be written in clear, proper English (British or American usage is accepted, but not a mixture of these). Manuscripts requiring substantial improvement of English usage may be returned to the author(s) for revision before the review process. Authors for whom English is not their mother tongue should have their manuscripts checked by a competent linguist or native English speaker before submission. The editors reserve the right to adjust style to certain standards of uniformity.

Submission, review and resubmission processes

1. The manuscripts must be submitted online as outlined in the Instructions to authors.
2. The manuscript will be sent to at least two reviewers and one member of the Editorial board.
3. After receiving reviews, the authors of articles must revise the manuscript according to the comments of the reviewers and return it to the editorial office.
4. If there is a need for re-review, the manuscript will be sent back to the reviewers and the authors must revise the manuscript once more.
5. When the manuscript has been revised by the authors, the Editorial board will make the final decision on the acceptability of the article for publication.

All scientific papers to be published in the journal are peer reviewed internationally. The duration of the reviewing process is variable, depending on numerous factors. However, typically the entire process from the submission of the first version of the manuscript to publication takes 4 to 6 months.

instructions to authors

PUBLICATION TYPES  

Research articles should describe results and applications of unpublished original research and describe novel theoretical considerations and ideas. The length of an abstract is up to 250 words. Mathematical expressions and citations in the abstract should be avoided. The abstract should be followed by keywords (max seven) with the first key word indicating the discipline of the study. Original research articles should be supported by relevant figures and tables and should be preferably no more than 26 double-spaced pages in length, including figures, tables, references and summary (12 printed pages in maximum). The length of an article should be maximally 12 pages (including figures, tables and references). Each page exceeding this volume shall be liable to a fee to the amount of €75 per page.    

Review articles should provide a broad and balanced overview of the current state of a research field, highlight the main methodologies and research techniques in use, and may identify gaps in existing knowledge. The length of an abstract is up to 250 words. The authors of review articles are asked to present also their CVs (not more than 100 words) and photographs. 

Short communications follow the structure of research articles, but their length should be no more than 9 double-spaced pages (2000 words), including figures, tables, references, notes and conclusion (4 printed pages in maximum). 

Announcements inform readers about scientific news and events, introduce books, new technologies and equipment. The length of an announcement is up to 1 printed page (500 words).

  • If your data are in a repository, include hyperlinks and persistent identifiers (e.g. DOI or accession number) for the data where available.
  • If your data cannot be shared openly, for example to protect study participant privacy, then this should be explained.
  • Include both original data generated in your research and any secondary data reuse that supports your results and analyses.
  • For manuscripts that do not report data, authors can state in their Data Availability Statement that data are contained within the article.

References
Proceedings of the Estonian Academy of Sciences has its reference templates available in many of the most popular reference management software products, such as ZoteroMendeleyPapers etc. These software products support Citation Style Language styles. Using citation plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal’s style.

References to the literature cited should be indicated at the appropriate place in the text. Either the author–year or numerical style of citing may be used. All references included in the list of references should also appear in the text and vice versa. Use abbreviated titles of journals in the list of references.

References to papers by the same author are sorted according to the number of authors (one, two, three or more). Those of a single author, ordered chronologically, are followed by papers with two authors arranged in alphabetical order according to the name of the second author (and chronologically, if needed). Papers with three or more authors cited in the text as, e.g. Jones et al., should be given in chronological order after those with two authors.

In the reference list the names of the first six authors should be cited followed by et al.

The original titles and publishers in Roman and Slavic alphabets should be retained. The English translation of the title can be provided in brackets immediately after the original title, reference to the original language (other than English) should be indicated in brackets at the end of the reference. Example: Versiani, A. F. V., Oribe, C. Y. and Rezende, S. F. L. R. 2013. A aprendizagem das organizações gerada pelas práticas formais no ambiente de trabalho (Organizational learning generated by formal practices in the work environment). RAM14(4), 15–44 (in Portuguese). 

If material is available online, the address and date of access should be given.

If the author–year style is used, references to the literature should be indicated at the appropriate place in the text by using the name(s) of the author(s) and the year of publishing. A reference list in alphabetical order should appear at the end of the article.

notations and abbreviations

Notations must be clear, compact, and consistent with standard usage. All notations and abbreviations should be defined in the text. Avoid abbreviations in the title and abstract. The full term for which an abbreviation stands should precede its first use in the text unless it is a standard unit of measurement.

Equations should be numbered consecutively with equation numbers enclosed in parentheses at the right margin of the page. In the text, reference to an equation should be in the form of an equation number enclosed in parentheses.

Illustrations should be prepared in their final format (i.e. no enlarging or reducing will be necessary) and fit into the print area of the journal. All illustrations should be sharp and readable. The maximum size of an illustration is that of one journal page (166 mm × 228 mm) or of one column (80 mm × 228 mm). All illustrations must be clearly numbered. Each illustration should be indicated at the appropriate place in the text. All illustrations must have self-explanatory legends. The text, tables, and illustrations should not repeat one another.

The lettering (upper- and lowercase letters, italic, bold) should follow the usage in the text. Different parts of a figure should be marked by lowercase letters in parentheses. The size of symbols and lettering should not be smaller than 1.5 mm.

Photographs (digital or scanned) should be saved as .tif or .eps files at a resolution of at least 300 dpi.

Colour illustrations should be in RGB and CMYK mode (resolution at least 300 dpi). Authors will be asked to cover the full cost for reproduction of colour artwork at a rate of €45 for one printed page. Colour figures online will be published free of charge.

If you wish to include any previously published figures or tables, written permission (for both the print and online formats) must be obtained from the copyright holder prior to submission, except for publications with open access licences. Identify previously published material by giving the original source in the form of a reference citation at the end of the figure/table caption.

Supplementary online material

Large data tables, figures, photos and long descriptions, which do not fit into the printed version of the paper, can be published as online supplementary material.

All supplementary data files should be included at the first submission. The files should be ready for publication – these are not edited by the journal copy-editor. The data should be cited in appropriate places in the article text and a section ‘Supplementary online data’ added before the list of references, listing all data files associated with the paper.

The submitting author, who is generally the corresponding author, is responsible for the manuscript during the submission and peer-review process. The submitting author must ensure that all eligible co-authors have been included in the author list and that they have all read and approved the submitted version of the manuscript. To submit your manuscript, register and log in to the submission website. If you have problems with our article submission system, please contact hedi.tonso@eap.ee.

Please take the time to read and follow the instructions, as doing so will ensure your paper matches the journal’s requirements.

The attachments sent through the submission system should include:

  • the covering letter (.doc, .docx, .rtf);
  • the text files of the paper in Microsoft Word (.doc, .docx, .rtf) or LATEX (.tex) format (other TEX versions are not accepted);
  • the PDF file of the paper (text, illustrations and tables in one file);
  • original files of illustrations and/or tables (.xls, .xlsx, .tif, .eps, .psd, .ai).

COVERING LETTER

A covering letter must be included with each manuscript submission. It should be concise and explain why the content of the paper is significant, placing the findings in the context of existing work. It should explain why the manuscript fits the scope of the journal

A covering letter should also include novelty explanation to address a wide or general audience what makes the research new, original, and significant. Novelty explanation should avoid jargon and highly technical language and should not exceed 300 characters with spaces. 

Covering letter is required to include the statements:

  • Author(s) confirm that neither the manuscript nor any parts of its content are currently under consideration or published in another journal.
  • All authors have approved the manuscript and agree with its submission to (journal name).
  • Author(s) must identify and declare any personal circumstances or interest that may be perceived as influencing the representation or interpretation of reported research results. If there is no conflict of interest, please state “The author(s) declare(s) no conflict of interest.”

We accept manuscripts already posted to a preprint server but kindly ask you to make us aware of that in the covering letter. Please include a link to the preprint, and as appropriate, state how the manuscript has been adjusted/updated between deposition and submission.

ORCID

The journal recommends that all authors submitting a paper register an account with Open Researcher and Contributor Identifier (ORCID). Registration provides a unique and persistent digital identifier for the account that enables accurate attribution and improves the discoverability of published papers, ensuring that the correct author receives the correct credit for their work. As the ORCID remains the same through out the lifetime of the account, changes of name, affiliation, or research area do not effect the discoverability of an author’s past work and aid correspondence with colleagues.

The journal recommends that all authors include an ORCID within their submitting author data. ORCID numbers should be added to the author data upon submission and will be published alongside the submitted paper, should it be accepted.

Authors will also need to follow these instructions on the ORCID website: https://support.orcid.org/hc/en-us/articles/360006896394-Auto-updates-time-saving-and-trust-building.

latex style files

Word versions are preferable in case the manuscript does not include complicated formulas. The authors are asked not to use specially defined macros. If it has been necessary to define the commands, they should be added to the text file.

article publication charges

When submitting an article to the Proceedings of the Estonian Academy of Sciences, the corresponding author agrees to pay the article processing charges (APC). Article processing charges (standard article publication fee or ‘fast track‘ fee, the excess page fee and cost of colour illustrations) are payable by the author, their institution or funder of the research.

Invoice with the banking data will be sent to the corresponding author. Prompt payment is advised, as the article will not be sent to the production cycle until payment is received. Payment should be made in Euro to the bank account of the Estonian Academy Publishers.

To partly cover publication costs of papers, the Estonian Academy Publishers charges a standard article publication fee of €600 per publication of papers up to 12 printed pages. For all papers longer than 12 printed pages, an additional charge of €75 will be requested for each extra page. Cost of Short communication publication fee (max. 4 printed pages) is 300 €. Cost of ‘Fast track’ publication is 1200 € for both, standard article and short communication. Authors will be asked to cover the full cost for reproduction of colour artwork at a rate of €45 for one printed page. Colour figures online will be published free of charge.
