Speech acts: Constative and performative

When are words just words and when do words force action? Linguist J.L. Austin divided words into two categories: constatives (words that describe a situation) and performatives (words that incite action). For instance is a "No running" sign describing your gait or are you not running because the sign prohibits it? Colleen Glenney Boggs describes how these categorizations give power to words and ultimately to your actions.
