GENERAL INSTRUCTIONS FOR AUTHORS

Scope and Focus

The RACSG is a high-level dissemination journal, aimed primarily at an audience interested in Science but without specific scientific training. Given this informative nature, it is recommended to avoid submitting "reviews" and to use the minimum number of formulas possible. Chemical equations, structural formulas, and mathematical equations must appear between successive lines of text. For the same reasons, authors are urged to limit references to the minimum necessary.

Submission Process

• Academy Endorsement: If none of the authors is an Academic (of any type), the manuscript should be submitted through an Academic.
• Cover Letter: The main author must accompany the manuscript submission with a cover letter stating the title and author(s) of the work.
• Required Forms: In any case, the main author must fill out the attached cover sheet indicating acceptance of two sections: (1) Transfer of copyright to the RAC, which must authorize its total or partial reproduction, and (2) Statement of Good Practice, Privacy Statement, and Ethics Statement.
• File Formats: Manuscripts should be sent for review, and potential acceptance, in standard formats: Word, LaTeX, XML, together with a PDF version of these.
• Submission Address: Manuscripts should be sent to the following email address: revistaracsg@rac.es

Manuscript Specifications

• Post-Acceptance: Once the manuscript is accepted, authors may receive additional instructions regarding the presentation of text, figures, tables, and references.
• Length: Except in exceptional cases (previously authorized by the Editorial Committee), the text length must not exceed 9,000 words (including figure captions and references).
• Multimedia: Additionally, the inclusion of videos or similar media may be proposed.

Structure of Manuscripts

The first page of the manuscript must include:

• Full Title: Maximum 15 words. No abbreviations should be included.
• Keywords: Maximum of 5. They must appear in brackets and be separated by slashes (/).
• Author Names: Without academic degrees. Names written i.e. John Michael Brown or J.M. Brown. Academic members must state their status. If no author is an Academic, the Academic through whom the publication request is processed must be listed in brackets at the end of the author list.
• Affiliations: In the following order: full name of the unit, institution, and location.
• Corresponding Author: Full address and email.
• Abstract: Maximum 250 words, in Spanish and English.

Bibliography

APA standards (https://www.scribbr.com/apa-citation-generator/) will be used as summarized below:

• In-text citations:
  • Single author: Author's last name followed by a comma and the year of publication, all in parentheses. E.g., (Anderson, 2011).
  • Two authors: Last names of both authors (with "&" between them) followed by a comma and the year of publication, all in parentheses. E.g., (Anderson & Jones, 2011).
  • Three or more authors: Last name of the first author followed by "et al", then a comma and the year of publication, all in parentheses. E.g., (Anderson et al, 2011).
• List of References: This will appear at the end of the article, ordered alphabetically by the first author's last name, following the aforementioned APA standards26.
  • Article Citation (inclusion of DOI is discretionary):
    • Anderson, P. W. (1972). More is different. Science, 177(4047), 393-396
    • Or: Anderson, P. W. (1972). More is different. Science, 177(4047), 393-396. doi10.1126/science.177.4047.393
    • Important Note: Articles must be listed with their full titles.
  Book Citation:
  • Anderson, P. W. (2011). More and different: notes from a thoughtful Curmudgeon. World Scientific.
  • Exclusions: Works submitted for publication, personal communications, or conference communications should not be included in the bibliography.

Figures and Tables

• Figures: Numbered consecutively in order of appearance using Arabic numerals (Figure 1, 2...). The text in the caption must contain sufficient information to be understood without referring to the general text.
• Tables: Numbered using Roman numerals (Table I...) and cited consecutively in the text. The caption text must contain sufficient information to be understood without referring to the general text.

Units, Abbreviations, and Symbols

• Units: International System (SI) units will be used.
• Journal Citations: Citations to the journal itself shall be made as follows: Rev. RACSG, 111, 94 (2011).
• Acronyms: The first time an acronym appears in the text, the full name must be provided. E.g., ESCA (Electron Spectroscopy for Chemical Analysis).

Language

The Journal of the Royal Academy of Exact, Physical and Natural Sciences accepts papers written in Spanish and English.

Additional specific rules for the "Kaleidoscope" section

"Kaleidoscope" ("Caleidoscopio") is a new section of the RACSG Journal intended to focus reader attention on a topic of current interest through a series of short articles on the subject, considered from different points of view. It will be published as an additional section to the standard articles, subject to the following specific rules:

• Initiation: An Academic ("Initiating Academic") selects a TOPIC, commits to writing a text on it, and coordinates with scientists (Academic or otherwise) willing to write the additional texts included in the TOPIC, communicating this information to the Editorial Committee.
• Scope: A TOPIC comprises a set of 3 to 5 very short articles : each <1200 words, maximum 5 references —preferably general—, maximum two figures), surrounding a scientific topic of interest which will be published as a block.
• Authorship: Each article will list the names of its authors and their affiliations.
• Technical Specs: For structure, bibliography, references, tables, and figures, authors should refer to the general instructions of the journal.
• Language: Each article within a TOPIC may be written either in Spanish or English.
• Abstract: A single abstract in Spanish and English will be included for the entire TOPIC block, making brief reference to the contents of the articles in the block.
• Review Process:
  • The Initiating Academic will perform the scientific review of the various manuscripts within the TOPIC using the general criteria of the Journal.
  • Once all reviewed manuscripts for the proposal are in hand, the Initiating Academic will send them as a group to the RACSG Journal for publication in the Scientific Kaleidoscope section.
  • The Editorial Committee will ensure the Kaleidoscope proposal meets the journal's criteria and will schedule the proposal for publication in the corresponding issue.
