In text citations should follow the author-date method whereby the author's last name and the year of publication for the source should appear in the text, for example, (Jones, 1998). Articles with one or two authors (Bogin & Rios, 2003) include all names in every in-text citation; articles with three, four, or more authors are abbreviated to the first author name plus et al. The complete reference list should appear alphabetically by name at the end of the paper. First names should be abbreviated.

Reference should be cited using citavi (DER Harvard style (author-date, english)), zotero (Elsevier-Harvard (with titles)), or Mendeley style.

A seperate BibTeX file (xxx.bib) should be added additionally to the reference list in the word file of the  main text.
