Citations*
In-text citations are provided by using the author-date system in the following order: ‘‘(Surname, year)’’. In-text citations for works with two authors are provided by adding the word ‘‘and’’ between the authors’ surnames (Lupan and Brown, 2007), whereas works with three or more authors are cited by using the first author’s surname followed by ‘‘et al.’’ (Midilli et al., 2016). If two or more works are to be cited in the same parentheses, citations are separated from one another with a ‘‘semicolon (;)’’ as follows: (Midilli et al., 2016; Bilgin et al., 2016).
When the parenthetical citation includes works of the same author from different years, the years of publication are listed in sequence, with the earliest first and the years are separated with a ‘‘comma (,)’’ as follows: (Küçük, 2013, 2014, ….). If two sources by the same author in the same year are cited in the same parentheses, lowercase letters (a, b, c) are used with the year as follows: (Küçük, 2013a, 2013b, …).
When naming the sources in the signal phrase, provide the year of the work in parentheses after the author’s surname as follows: ‘‘According to Turan (2012)…’’, or ‘‘As argued by Turan et al. (2014) …’’.
