This document discusses the importance of indicating the scope and delimitation of a study. It provides two examples from actual studies. The first study examines consumer response to PETA's advocacy advertisements for vegetarianism, focusing on how the ads catch attention, affect lifestyles, and generate action. The second study focuses on Milo Marathon as a corporate social responsibility event, using survey responses from participants in the 42km and 21km distances to examine the event's charitable benefits.
