Note on author order: In most cases my coauthors and I have
followed the common
mathematics/theoretical computer science convention
of alphabeticallyordered authors. Unlike the standard in some other areas of
science, in my papers there is no
lead author or second author or special place for a principal investigator.
It's just alphabetical.

This version corrects an error in the proof of Theorem 2.4 in the conference version Constructive dimension and weak truthtable degrees
from CiE 2007,
and the revised proof only applies to Turing degrees, hence the change of the name of the paper. Also, the printed version of this paper
