General Information
Welcome to the official website of the Nigerian Actuarial Journal (NAJ). As an international, peer-reviewed journal, we are committed to publishing high-quality, original research that advances the field of actuarial science. Proudly published by the Actuarial Academy of Nigeria, this platform serves as a hub for scholars, practitioners, and enthusiasts to explore innovative insights and developments in the profession.
All submitted manuscripts undergo a rigorous peer-review process to ensure the
highest quality of published articles. The journal uses a double-blind review system, where the
identities of both authors and reviewers are concealed from each other.
Types of Papers
Original Research Papers
These papers report original research findings that have not been published elsewhere.
They should contain new data or interpretations of existing data that contribute significantly
to the advancement of management sciences. Length: 4,000-8,000 words including abstract, tables,
figures, and references.
Review Articles
Review articles provide a comprehensive analysis and evaluation of recent developments and
current trends in a specific field of management sciences. These articles should synthesize existing
knowledge and identify gaps for future research. Review articles are typically invited by the
editors, but unsolicited reviews of high quality will also be considered. Length: up to 10,000 words.
Short Communications
Short communications are brief reports of significant new findings that warrant rapid publication.
They should be concise and focused on a single subject. Length: 2,000-3,000 words including all elements.
Book Reviews
Book reviews provide critical evaluations of recently published books relevant to management sciences.
These reviews are typically solicited by the editors. Length: 800-1,500 words.
Manuscript Preparation
Language and Style
Manuscripts must be written in clear, grammatically correct English (British English spelling and grammar).
Authors whose native language is not English are strongly advised to have their manuscripts checked by
a native English speaker or a professional language editing service before submission.
File Format
Manuscripts should be submitted as Microsoft Word documents (.doc or .docx) or PDF files.
The text should be in single-column format with double line spacing throughout, including
abstracts, footnotes, and references. Use 12-point Times New Roman font with 2.5 cm (1 inch)
margins on all sides.
Length
Manuscripts should be concise and written in a clear, straightforward style. The recommended
length for each type of submission is provided above. Excessively long manuscripts may be returned
to authors for shortening before the review process begins.
Units of Measurement
Use the International System of Units (SI) for all measurements. If other units are mentioned,
please provide their equivalent in SI units in parentheses.
Abbreviations
Define abbreviations and acronyms at their first occurrence in both the abstract and the main text.
Ensure consistency of abbreviations throughout the article.
Manuscript Structure
Manuscripts should be arranged in the following order:
The title page should include:
- A concise and informative title (avoid abbreviations where possible)
- The full names of all authors
- The affiliations of all authors, including institution, city, and country
- The email address of the corresponding author
- A running title (short title) of no more than 50 characters including spaces
Provide a structured abstract of 250-300 words. The abstract should be self-contained and
citation-free, summarizing the purpose of the study, basic procedures, main findings, and
principal conclusions. For original research papers, the abstract should be structured with
the following subheadings: Background, Methods, Results, and Conclusion.
Provide 4-6 keywords that capture the main topics of the paper. Avoid general terms, plural
terms, and multiple concepts (avoid, for example, "and", "of"). Keywords will be used for
indexing purposes.
The introduction should clearly state the background and objectives of the research,
providing an adequate background and avoiding a detailed literature survey or a summary
of the results. End with a brief statement of what has been achieved in the study.
This section should provide sufficient detail to allow the work to be reproduced.
Methods already published should be indicated by a reference, with only relevant
modifications described. For studies involving human subjects or experimental animals,
include a statement specifying the appropriate institutional review board approval.
Results should be clear and concise. Present your results in a logical sequence in text,
tables, and figures. Do not duplicate data in tables or figures in the text.
This section should explore the significance of the results, not repeat them. A combined
Results and Discussion section may be appropriate for some papers. Avoid extensive citations
and discussion of published literature.
The main conclusions of the study may be presented in a short Conclusions section,
which may stand alone or form a subsection of the Discussion section. Highlight the
significance and implications of your findings.
Acknowledge any funding sources and individuals who provided help during the research
but are not listed as authors. Ensure that anyone named in the acknowledgments has
agreed to be mentioned.
See the References Format section below for details.

They should be numbered consecutively according to their appearance in the text. Figure captions
should be provided on a separate page after the tables, with a brief title and explanation of
any symbols used. Ensure that figures are clear and legible, with appropriate axis labels and
units clearly marked.
