the way of cite
- reference should be cited in council of science editors (cse) name-year style, e.g. (Ritzmann 1974; Feller 1981; Fauci 2002)’, or ‘. . . see Smith (1991, p. 15)’
- same author published in different years: e.g. ‘(Smith 1970, 1975)’.
- same author published in same years: e.g. ‘(Andrews 1960a, 1960b)’
- if the authors names are the same and the year of publication are the same: e.g. ‘(Dawson J 1986; Dawson M 1986)’.
- if a work has two authors, give both names: e.g. ‘(Weinstein and Swartz 1974)’.
- if a work has three authors, give only the first author's name followed by 'et al'. + the year of publication. e.g. ‘(Ochi et al. 2003)’.
- if works have the first author's name same, and the years are identical, then include enough co-authors names to eliminate ambiguity, e.g. ‘(Martinez, Fuentes, et al. 1990; Martinez, Fuentes, Ortiz, et al. 1990)’
