Authors' note on the printed second edition:
Elsevier introduced many inappropriate abbreviations (e.g., LP for
all words "long period", even in the regular text),
ignoring authors repeated requests.
So personally I prefer the original version, except those newly added parts (not so many, though).
The layout of figures is also much nicer and approproate in the original edition, I think (HK).
