More than one work citation:

If citing two or more works within the same parentheses, they should be in alphabetical order of authors and each citation separated by a semi-colon, as (Phillips et al., 2010; Rolfe et al., 2010).

Citation for two or more works by the same author but in separate years:
Give the author's last name followed by the years in ascending order and each separated by a comma, as (Davies, 2008, 2010, 2012).

Citation for two or more works by the same author published in the same year:

The suffixes are assigned in the reference list, where these types of references are ordered alphabetically by title (of the article, chapter, or book).


In case if it is difficult to identify the author of a webpage, decide who is responsible for the page and that person or corporate body can be referenced as the author.

If Results and Discussion are presented separately, Results section should not include material appropriate to the Discussion section. The Discussion section should explore the significance/implications of the results without repeating them.
