General Notes

The RPES Journal accepts submissions and publishes manuscripts written only in English. Either British or American English may be used, but the dialect used should be followed consistently throughout the manuscript.

A manuscript should be no more than 9000 words; this limit includes figures, references, and tables, while shorter ones are preferred. However, this does not impose an absolute page limit on manuscripts; longer manuscripts of merit can be published in the journal.

Manuscript Organization

All manuscripts must contain the essential elements for a research article or literature review article: These are: Title, Abstract, Introduction, Materials and Methods, Results, Discussion and/or Conclusions, Figures and Tables with Captions, and any Supplementary Material required. The text should be in single-column format. In addition, papers should be prepared with Microsoft Word in .docx, .doc or in .rtf file formats. Double spacing and 12-point Times New Roman are suggested for submission.

Number the pages consecutively starting with the first page, which should contain the following:

Running Head: Please provide a shortened title for your submission.

Title: Please provide a title no more than 20 words. Titles should be brief as possible and thus readers can discover your article.

Abstract: Please provide a short abstract of 300 words maximum. The abstract should not contain any undefined abbreviations or unspecified references.

Keywords: Please provide four to six key words or short phrases in alphabetical order.

Abbreviations: Please include all abbreviations at first use.

Contribution to the Literature
Including a contribution to the literature is not mandatory. However, you are welcome to summarize the ways your paper contributes to the existing literature in three bullet points using a maximum of 100 words. You can also emphasize the originality and the significance of your work in terms of research questions, employed methods, and/or findings and results. However, do not give any implications in this section. The purpose of this section is to help the readers to be able to compare and contrast your work to previous work, if any exists, and to understand how your work advances the scholarship in the field.

Please provide a background information and state the objectives of your research in light of the existing literature.

Materials and Methods
Please provide all details to answer your research questions.

Results should be clear and concise.

A Discussion should firstly summarize the significance of the results of the work. However, results should not exactly repeated in this sections. Later, similarities and differences should be debated between previous findings and obtained results. Results and Discussion sections may be combined.

The main conclusion(s) of the study may be presented in a short Conclusions section, as a stand-alone section or in form of a subsection of the Discussion or Results and Discussion section.

Quotations of less than 40 words should be incorporated into the text using double quotation marks. Quotations longer than 40 words should be in a freestanding block of text without quotation marks, per APA style.

Section Headings
First-, second-, third-, and fourth-order headings should be clearly distinguishable.

Supplementary material should be collected in an Appendix and placed before the Notes and References.

Please use end notes rather than footnotes. Notes should be indicated by consecutive superscript numbers in the text and listed at the end of the article before the References. A source reference note should be indicated by means of an asterisk after the title. This note should be placed at the bottom of the first page.

Acknowledgements of people, grants, funds, etc. should be placed in a separate section before the References.

All citations must be present in the reference section, and all references cited in the text. If exists, the DOI number must be included in all references.

RPES uses the 'Name. Year' style with an alphabetized reference list.

Journal reference format: List of authors (with initials). Publication year. Full article title. Full title of the Journal, volume: page extents. DOI (if available).

All photographs, graphs, and diagrams should be referred to as figures and should be numbered consecutively (1, 2, etc.). Multi-part figures should be labeled with lower case letters (a, b, etc.). Please insert keys and scale bars directly in the figures. Relatively small text and great variation in text sizes within figures should be avoided as figures are often reduced in size. Figures may be re-sized to fit in the column(s) of the journal. Provide a detailed legend (without abbreviations) for each figure, refer to the figure in the text, and note its approximate location in the margin. Please place the legends in the manuscript after the references.

High quality (300 dpi or higher) original digital files in one of the common file formats such as jpeg, tiff, or png must be submitted as separate files and not embedded in the text. Charts and graphs must include a separate MS Excel file along with the text file so that changes can be made in their appearance.

Tables should be numbered consecutively. In tables, footnotes are preferable to long explanatory material in either the heading or the body of the table. Such explanatory footnotes, identified by superscript letters, should be placed immediately below the table. Please provide a caption (without abbreviations) for each table, refer to the table in the text, and note its approximate location in the margin. Finally, please place the table captions after the figure legends in the manuscript.

Figures and tables should be presented on separate sheets after the main text.


Proofs will be sent to the corresponding author. One corrected proof, together with the original edited manuscript, should be returned to the publisher within three days of receipt by e-mail (pdf version).

Obtaining Permissions

It is the responsibility of the author to obtain written permission for a quotation from unpublished material, and for all quotations in excess of 250 words in one extract or 500 words in total from any work still in copyright. Prior written permission is also required for inclusion of figures/pictures, tables or poems from unpublished or copyrighted material.
