Article requirements

  1. Format: The submitted articles should be in Microsoft Word format. Other formats are not allowed. The article should be in Times New Roman, single-spaced and font size 12.
  1. Article Length: Articles should be between 5000 and 8000 words in length. This includes all text including references and appendices. The article must be preceded by an abstract of no more than 150 words and up to Four (4) keywords. Keywords should be the ones that explain the principle topics or issues of the article. They must be appropriate and short.
  2. Structure of the Abstract: The abstract is expected to be presented in a brief way and should include a brief summary of objectives of the study, methodologies and approaches, key findings, recommendations and implications.
  1. Sections of the article: Articles shall have un-numbered sections and subsections headings as follows: Section headings shall be in CAPITALS (UPPER CASE) while subsection headings shall be in Title Case. Authors are expected not to use bullets and numbering in their articles.
  2. Article Title: A title of not more than fifteen words should be provided. The authors should write their full names precisely, correct email addresses, and affiliation of each contributing author. The affiliation should be where they were based at the time of doing the research.
  1. Article Classification and Uniformity: Authors shall adapt a nearly-uniform format and reference style for submitted manuscripts. The suggested structure takes cognizance that while for some obvious reasons it may not be viable that all papers possess identical structure, it is desirable to have uniformity in terms of the flow of the papers’ contents. Thus, the objective is not for the papers to have sub-headings as outlined below, but for the contents to rhyme with the outline. The proposed outline also aims at, among other things, giving some flexibility to authors and keeping the number of subheadings to reasonable level (‘ideally’ between four and six).
  • Papers based on field researches
  1. Introduction: This part introduces the idea behind the paper paving the way and leading the reader to the objective. Preliminary observations and literature, motivation, the significance of paper as well as research questions (where appropriate) are expected in this part.
  2. Theoretical background and review of literature: The aim is to make the issue addressed in the paper apparent as well as contribute in developing and understanding the methodology.
  • Methodology: This part needs to cover the way the study was designed and carried out (i.e. including data collection)
  1. Analysis and interpretation of findings: The findings should be aligned to the objectives of the study. The author should clearly show how the objectives were achieved
  2. Discussion of the findings: The focus here is to discuss the findings by addressing possible explanations of the findings, comparing the results with those of the previous results, linking your arguments with those of the previous studies.
  3. Generalizations from the study/Conclusions and implication: The author is expected to briefly present what the paper was all about, concluding remarks based on the findings and theories, positioning the study/paper in the body of knowledge, and to draw theoretical, practical and policy implications.
  • References: See Section 3 on Citations, Notes and References
  • Papers solely based on Literature Review (library research): The structure needs to be similar to the one given above – but most likely with modified methodology and approaches.
  • Practical/experiential papers: These are likely to be more descriptive in nature with core focus above sections in 6.1, but with some modifications. Articles of this kind should be supported/backed-up with relevant literature as appropriate.
  1. Notes/Endnotes: Notes or Endnotes should be used only if absolutely necessary and must be identified in the text by consecutive numbers, enclosed in square brackets and listed at the end of the article.
  2. Citations, Notes and References: References to other publications must be in APA style and carefully checked for completeness, accuracy and consistency. The authors should follow the style presented below:
