Title: the title of the report in English and Bulgarian must be short, each word written in capital letter in Times New Roman font (12 point, bold) and centered.

Author’s information: must be centered and in Times New Roman font. This section contains the full names of the authors (12 point, bold); name of the organization, e-mail for contact with authors (10 point, italic). All contributing authors’ names should be added to the ScholarOne submission, and their names arranged in the correct order for publication. It is the responsibility of the lead author to ensure that the list of authors and individual contribution to the study of each of them are clearly indicated.

Abstract. The abstract of the articles, whose main text is in Bulgarian should be written also in English. For publications that are written in English, the abstract should only be in English. It should be short and clear and concisely contain the following elements:

The maximum length of the abstract should not exceed 300 words.

Keywords (specify up to 5 keywords).

Running Title– up to 5–7 words.

16. Introduction.

The purpose of the introduction is to convince readers that the published research contains novelty and it is applicable. It answers the following questions:

  • What is the main problem?
  • Are there any existing solutions (indicates the level of study the problem at the moment)?
  • What are the best solutions according to the author’s/s’ opinion?
  • What is the main limitation of the research?
  • What is expected to be achieved by the author of the research?

17Main Text

The main text is structured into separate sections, distinguished by their titles (headings should be brief, with clear indication of the differences between their hierarchy). The preferred format for writing the main titles is to be bold format and subtitles to be written in italics. Font – Times New Roman 12, capitals, left alignment). The main text should include:

Purpose of the study. The purpose and objectives of the study should ensure the understanding of the publication’s focus and should justify its structure. After that, authors should specify:

  • What is the significance of the publication?
  • Why the publication is important and original?
  • To whom is the publication designed?

Additionally, it can be discussed potential utility of practice, importance for future studies, detailed limitations of the study and others.

Main thesis and hypothesis of the research. Authors’ arguments about their merit are presented.

Material and Methods. The author should indicate the subject and main methods used by him in a separate title. Author should demonstrate that the methodology is robust and appropriate to achieve the objectives. It is expected by the author to focus on the main theme, to point the main stages of his research, to show the used methods and influences that determine the chosen approach by him/her, to give arguments why he/she has chosen specific examples and others.

Results. When presenting the results, it is important authors to focus on the essentials. The publication must contain only the essential facts and those with a wider meaning, without giving many details of every possible statistics. If development is full of statistics, it is possible to prevail over the conclusions and after all the publication to be seen primarily as an enumeration of facts, not a scientific study. The main thesis of the author must be clearly traceable and steadily established.

When describing the results author should seek answers to the following questions:

  • Do you provide interpretation for each of the submitted results you want?
  • Are the results consistent with what other researchers have found?
  • Are there any differences? Why?
  • Are there any limitations?
  • Does the discussion logically lead the reader to your conclusion?

It is important when presenting the results not to make statements that go beyond what results can acknowledge.

18. Discussion

Authors should discuss the results and how they can be interpreted in perspective of previous studies and according to the working hypotheses. Future research directions may also be mentioned. 

19. Conclusion

The conclusion should be a comprehensive summary of the research giving an important scientific message (it could be found in the abstract). It should be emphasized what is different in the research results, what stands out in the design or it is unexpected.

20. Acknowledgements (Funding).

The funding sources of the scientific research should be added in Step 5 of the submission process on ScholarOne system. Funding sources of the scientific research in the article are presented in section “Acknowledgements”.
