Better Way of Testing and Replacing List Elements?

The code below replaces the negative values in a list with zero, and
is an example of a type of operation I use a lot:
xxx = {1, 2, 3, 4, 5, -6, -7, 8, 9, 10, -1, 11, 12};
ReplacePart[xxx, Position[Map[Negative, xxx], True] -> 0]
Is there a "better" way of doing this (fewer function calls, more
efficient)?
My feeling is that I'm doing this in an awkward way.
