Abstract

present different methodological approaches that can be used to investigate problems in a relevant scientific field and to encourage innovation.• Letters to the Editor -a response to authors of an original publication, or a very small article that may be relevant to readers. • Editorials -articles written by members of the Editorial Board. Research PapersArticles reporting research may be full length or brief reports. These should report original research findings within the journal's scope. Papers should generally be a maximum of 4000 words in length, excluding a maximum of 5 tables, references, and abstract of the article, whilst it is recommended that the number of references should not exceed 36. Review PapersComprehensive, authoritative, reviews within the journal's scope. There are two types of review papers:• systematic review papers: respond to a specific research question, accrue from criterion-based selection of sources, include a quantitative synthesis and a statistical method (meta-analysis), and should adhere to PRISMA guidelines. Guidelines used for abstracting data and assessing data quality and validity should be noted in methods section. • narrative review papers: the research question may be broad, and the scope of this review is to discuss a specific topic and keep the readers up-to-date about it. This type of review does not necessarily include a methodological approach and its synthesis is usually qualitative. Narrative reviews should include in a developments section, with details regarding data sources used, keywords applied, time restrictions and study types selected. Developments should be based on actual review articles. All review papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50. Conclusion of the reviews should be specific and stem from the findings. Short ReportsBrief reports of data from original research. Short reports are shorter versions of original articles, may include one table or figure, should not exceed 1500 words, and it is recommended that the number of references should not exceed 15. Short reports are suitable for the presentation of research that extends previously published research, including the reporting of additional controls and confirmatory results in other settings, as well as negative results. Authors must clearly acknowledge any work upon which they are building, both published and unpublished. Methodology PapersMethodology papers will present different methodological approaches that can be used to investigate problems in a relevant scientific field and to encourage innovation. It is suggested that case studies or practical examples, which can be existing ones, are included to demonstrate the consistency and applicability of the methodology. Methodology papers should be generally less than 6000 words, excluding abstract, tables, figures and references. References should not exceed 50.
