  I believe Barr et al (2013) has become the canonical reference
for "put everything in the model".  Doug Bates has mentioned to
me that he was working on a response, with some co-authors,
that disagrees with Barr et al.; perhaps he will chime in on
its status.  I have a book chapter in press
(Fox, G. Negrete-Yankelevich, S. and Sosa, V. (Eds.) Ecological Statistics:
from principles to application. Oxford University Press) that discusses
this issue.  

  Suggestions from the rest of the community are welcome, as always.
