Author Guidelines

The contributions should be typewritten on A4 size papers (297 mm × 210 mm) with font Times New Roman and 1.0 line spacing. Margins of 2.5 cm should be on all sides except the left margin. The left margin should be 3 cm. The full paper should not exceed 20 pages.

Preparation of Manuscripts
Contributions should be typewritten on A4 size paper (297 mm × 210 mm) with font Times New Roman and 1.5 line spacing. Margins of 2.5 cm should be used on all sides except the left margin. The left margin should be 3 cm. The full paper should not exceed 20 pages.

Preparation of the Title Page
This should contain the title, authors’ names and affiliations, and complete contact details of the corresponding author.

Title of the Paper (14pt, bold)
Titles should be simple and concise. Begin the first word with a capital letter; thereafter capitalise only proper or trade names and chemical symbols.
Author(s) Name(s) (12pt, bold)
Use only one form of your full name (maximum of three names) as an author in all of your publications.
Affiliation(s) of Author(s) (12pt, italic, normal)
Write names and postal addresses of all institutions in full.
Corresponding author postal address, telephone numbers, ORCID ID and e-mail address.

Preparation of the Blinded Manuscript
Besides the obvious need to remove names and affiliations under the title within the manuscript, there are other steps that need to be taken to ensure the manuscript is correctly prepared for double-blind peer review. To assist with this process the key items that need to be observed are as follows:

Use the third person to refer to work the authors have previously undertaken, e.g. replace any phrases like “as we have shown before” with “… has been shown before¹” .
Make sure figures do not contain any affiliation-related identifier or logo
Remove references to funding sources
Do not include acknowledgments in the blinded manuscript. It can be included after the review process in the accepted paper.
Remove any identifying information, including author names, from file names and ensure document properties are also anonymised.

Blinded manuscript should contain the following sections.

Title of the Paper (14pt, bold)
Must be the same as on the title page.

Abstract (font-12, normal)
An abstract must accompany each manuscript. The abstract should be less than 200 words and must be completely self-contained. This means, for example, that numbered references cannot be used in the Abstract; instead, if a reference is central and essential to describing the work, it must be cited in full.

Keywords (font-12, normal)
Keywords should be given for indexing and information retrieval.

Main body of the paper (font-12, normal)
The body of the paper (text and math) should be divided into sections with the use of section headings and subheadings.

1. PRINCIPAL HEADING (font-12, bold)
Left-justified heading, all capital letters, preceded by an Arabic numeral (1, 2, etc.) and a period.

1.1 Subheading
Left-justified heading, first word with a capital letter, preceded by Arabic numerals (1.1, 1.2, 2.1, etc.) and a period.

Leave double space before section headings or sub-headings.

Citations, Figures and Tables (font-11, normal)
In the body of the paper all references, figures, and tables must be cited consecutively in numerical order. Tables and Figures should be numbered with Arabic numerals (Figure 1, Table 1, etc.) Use (a), (b), (c), etc., to label the parts of figures (Figure 1(a), Figure 1(b), etc.). All figures, and tables must be placed within the text at the appropriate points.

Equations
Equations that are important, long, complex, or referenced later in the paper are set off from the text (displayed) and may be numbered consecutively with right-justified Arabic numbers within parentheses (1), (2), (3), etc.

ACKNOWLEDGEMENTS
The acknowledgement section follows the main body of the paper. One paragraph is suggested, with acknowledgement of financial support listed at the end. A principal heading is used for this section, but the section is not numbered

Footnotes (font-10, normal)
Use lowercase letters a, b, c, etc. to label the footnotes. Refer to the footnote in the body text by the insertion of label as a superscript.

REFERENCES (font-11, normal, single spacing)
Citation of reference information should be as simple and as concise as possible. A superscript number in Arabic numerals should indicate references in the text. Follow the instructions given below when preparing the final reference list in numerical order at the end of the manuscript. Name with initials of each author should be included. It is mandatory to include DOI for each reference if it is available.

Peer Review Process
Manuscripts submitted by the authors are subject to a preliminary screening based on appropriateness of the theme and quality of the content of the manuscript. Manuscripts that pass initial screening then undergo a double-blind peer review, which means that both the reviewer and author identities are concealed from the reviewers, and vice versa, throughout the review process. To facilitate this, authors need to ensure that their manuscripts are prepared in a way that does not give away their identity. Submit the Title Page containing the Authors details and Blinded Manuscript with no author details as two separate files.

Editor in Chief will assign a member of the editorial board based on the subject area of the article. At least two reviewers in the same or a related field will be assigned by the Editor to carry out the review based on the evaluation criteria. Based on the recommendation of the assigned Editor and the evaluation reports of the reviewers, the Editor in Chief then makes a final decision for acceptance, request for revision, or rejection of the manuscript.

Peer-review process normally takes from 12 weeks to 16 weeks. However, in some cases it can deviate either way from this time frame.

If the manuscript is accepted with revisions, the reviewers’ comments and the edited manuscript, if available, will be sent to the corresponding author for revisions. Normally, a maximum period of four weeks will be given to submit the revised manuscript. When submitting the revised manuscript, make clear what passages have been revised and which are unchanged. Also include a separate detailed and step-by-step response to the comments and points that the reviewers make. Revised manuscript should be submitted through the relevant SLJP submission page as a revised file.

Submission Preparation Checklist
