Lindsey and Vigil (1999) found that both men and women reacted more positively toward a wink from an opposite sex stranger than they did from a same sex stranger.

Men and women both seem to be more comfortable when they are winked at by a stranger who is a member of the opposite sex than of the same sex (Lindsey & Vigil, 1999).

A number of studies have shown that women in public relations are discriminated against in terms of salary (see review in Krider & Ross, 1997).

Krider and Ross (1997) cited the work of other researchers as support for a need to examine the role that women were playing in public relations.

"Our conclusion is that winking at same-sex individuals is regarded as a socially inappropriate behavior, particularly when given by a stranger" (Lindsey & Vigil, 1999, p. 262).

You should find and cite from primary sources. However, when you are unable to do this, you should make it clear to the reader where you retrieved the information. For example:

Krider and Ross (1997) quoted Toth and Grunig (1993) as calling for "considering through a feminist analysis the breadth of roles that women perform under the managerial label" (p. 153).
