Submissions

Author Guidelines

The author (s) of the submitted manuscript acknowledges that the submitted paper has not been published or submitted for publication in any other journal. The author(s) will not submit the paper for publication elsewhere unless author(s) is informed that the paper may be submitted for publication after the assessment process is completed and the paper is rejected for publication in NJS. The author (s) also acknowledges that the submitted paper will not be withdrawn unless it is rejected for publication in NJS.

Manuscripts submitted to the journal as original articles should be divided into Title, Title page, Structured Abstract, Keywords, Main Text, Acknowledgements, Conflict of Interest, References, Appendices (if any) and Supportive/Supplementary Material (if any). The manuscript should be written in 10 pt Times New Roman font, 1.5 spaced between rows with 1 inch margins.

Manuscript Length
Original research paper: 4000-8000 words; Review article: 6000-12000 words; Short communication: 2000-5000 words.

Title
The title should be precise and brief. Authors should avoid the use of non-standard abbreviations. The title must be written in title case except for articles, conjunctions and prepositions in 12 pt Times New Roman font.

Title page
Title page should include paper title, author(s) full name and affiliation, corresponding author(s) names complete affiliation/address, along with phone, fax and email.

Structured Abstract
The abstract of an article should be clear, concise and accurate summary, having no more than 250 words. Use of abbreviations should be avoided and the references should not be cited in the abstract. Ideally, each abstract should include the following sub-headings, but these may vary according to requirements of the article.

• Background
• Objective
• Materials and Methods
• Results
• Conclusion

Keywords
6 to 8 keywords must be provided.

Main Text
The main text should begin on a separate page. The text may be subdivided further according to the areas to be discussed, which should be followed by Conflict of Interest, Acknowledgements and Reference section. For review, the manuscript should be divided into title page, abstract and the main text. The text may be subdivided further according to the areas to be discussed, which should be followed by the Acknowledgements and Reference sections. The main text must be structured into separate sections as Introduction, Materials and Methods, Results, Discussion, Conclusion, Conflict of Interest, Acknowledgements and References. The Review Article should mention any previous important recent and old reviews in the field and contain a comprehensive discussion starting with the general background of the field. It should then go on to discuss the salient features of recent developments. The authors should avoid presenting material which has already been published in a previous review. The authors are advised to present and discuss their observations in brief. The manuscript style must be uniform throughout the text and 10 pt Times New Roman fonts should be used with 1 inch margin and 1.5 spaced. The full term for an abbreviation should precede its first appearance in the text unless it is a standard unit of measurement.

Greek Symbols and Special Characters
Greek symbols and special characters often undergo formatting changes and get corrupted or lost during preparation of manuscript for publication. To ensure that all special characters used are embedded in the text, these special characters should be inserted as a symbol but should not be a result of any format styling. All kinds of measurements should be reported only in International System of Units (SI).

Mathematical Material
Units
The following guidelines for using units should be observed.

• The number (numeral) should be separated from the unit followed by a full space, e.g., 1.5 gm.
• The units should have a single form for both singular and plural, i.e., 1.5 cm and 5.2 cm.
• The symbols for units should be printed in lower-case roman type without periods. Units derived from proper names, however, should be abbreviated with initial capital letters, i.e., coulomb (C), Weber (Wb).
• The abbreviated form of a unit must be used after a number given in numerals: 1 cm (not 1 centimeter).
• Decimal multiples of units should be indicated by the use of prefixes. The combination of prefix and unit symbol is treated as a single symbol. For instance, such a combination can be raised to a power, i.e., cm². Compound units should be written as 1 g cm² or g cm² s^-2, with a thin space between unit parts. Avoid ambiguous compound units, e.g., 2 J/cm³/s. Write instead, for example, 2 J cm ^-3 s^-1.

Symbols
Mathematical symbols must be defined immediately where they are introduced.

Characters
Character fonts:
The italic font should be used for mathematical symbols along with variables. However, the constants appearing with the symbols or variables should not be italic. For instance,

Equation numbering
A principal equation and subordinate equations may be numbered (1), (1a), (1b), etc.

Bracketing and Grouping sequence
For the purpose of grouping, the sequence of bracketing preferred is {[()]}, working outwards in sets ( ), [ ], and {}.
{ [ ( { [ ( ) ] } ) ] }

Fractions
Fractions can be “built up” with a fraction bar,  , “slashed” with a solidus, (a + b)/c, or written with a negative exponent, (a + b)c^-1. In text all fractions must be either slashed or written with a negative exponent.

Mathematical terms
The use of the following standard symbols is recommended.

Conflict of Interest
Any potential conflict of interest must be clearly acknowledged under the heading ‘Conflict of Interest’.

Acknowledgements

Editorial Review
The review process starts with editorial review of the submitted articles. The main objective of the editorial review is to decide whether the submitted article is good enough to be forwarded for peer review or not. If corrections are required at this stage regarding overall writing of the paper and whether authors have followed the guidelines of the journal are checked. The main requirement at this stage is to check whether the submitted paper is suitable for publication in the journal or not and has substantial content that is required for publication in NJS. If a paper fails at this stage, the paper will be returned back to the author with notice. Editorial review is accomplished with at least three of the editorial board members. A paper submitted by an author who is also an editorial board member will also go through editorial review but the author will have no role in editorial review process.

Peer Review
Peer review is done with one or two reviewers blinded about the authors name except in the case if an editorial board member is peer reviewer. Detail review of the paper is done at this stage covering every aspect of the paper except formatting. Peer review is sent to accomplished and prominent statisticians, professors or professionals working in government or other sectors. In the review, a reviewer needs to categorical state whether a paper is rejected, needs major/minor corrections for acceptance or accepted without any need for correction. Based upon the peer review report, the final decision about the paper is made jointly by the editor-in-chief and managing editor of the journal. In case, if an editorial board member is an author, then the member will not have any role in selection of peer reviewer or role in any decision making process regarding the paper.

The entire review process is scheduled to be completed within about two months. However, this will depend upon the selection of the peer reviewer and the duration spent in peer review process.

Language
Manuscripts submitted containing language inconsistencies will not be published. Authors must seek professional assistance for correction of grammatical, scientific and typographical errors.

Proof reading
Authors are required to proofread the PDF versions of their manuscripts before submission. To avoid delays in publication, proofs should be checked immediately for typographical errors and returned within one week. Major changes are not acceptable at the proof stage. If unable to send corrections within one week due to some reason, the author(s) must at least send an acknowledgement on receiving the galley proofs or the article will be published exactly as received and the publishers will not be responsible for any error occurring in the manuscript in this regard.

The corresponding author will be solely responsible for ensuring that the revised version of the manuscript incorporating all the submitted corrections receives the approval of all the authors of the manuscript.

Copyright letter
It is a mandatory requirement that a signed copyright letter needs to be submitted along with the manuscript by the principal author and corresponding author (both needs to sign if principal author is different from corresponding author) declaring the potential competing interests, acknowledging contributions from authors  and certifying that the paper is prepared according to the 'Author Guidelines'. All inconsistencies in the text and in the reference section, and any typographical errors must be carefully checked and corrected before the submission of the manuscript. The article contains no such material or information that may be unlawful, defamatory, fabricated or plagiarized. The authors acknowledge that the publishers have the legal right to take appropriate action against the authors for any of such violations.

License agreement
Principal author needs to agree and sign the License Agreement with the publisher of NJS for the purpose of granting licensing right of publication in NJS.
