user4201: In versions of After Effects prior to CS5, there are opacity map presets such as Fade In, Fade Out, Constant, etc.
I can see Opacity Map under Particle in the CS6 CC Particle World, but how do I get the presets?

user4426: In the newer versions of CC Particle World the opacity map presets have been removed.  
The only way to set opacity now is by drawing a curve on the graph.  See screenshot below:
