"Five Socio-Economic Variables"

Harman, "Modern Factor Analysis", Third Edition Revised,
on page 135, gives the Principal Components of "Five
Socio-Economic Variables". My computed result is below.
There is a difference: all the signs of the second
column are reversed between Harman's and my results.
Is there any confirmation of this, or am I in error?
I have been hoping to use these published results to
confirm my code, but between this and my previous
post ("Twenty-Four Psychological Tests"), I am not
encouraged.
