  We continue investigation of the effect of position in announcements of newly
received articles, a single day artifact, with citations received over the
course of ensuing years. Earlier work [arXiv:0907.4740, arXiv:0805.0307]
focused on the "visibility" effect for positions near the beginnings of
announcements, and on the "self-promotion" effect associated to authors
intentionally aiming for these positions, with both found correlated to a later
enhanced citation rate. Here we consider a "reverse-visibility" effect for
positions near the ends of announcements, and on a "procrastination" effect
associated to submissions made within the 20 minute period just before the
daily deadline. For two large subcommunities of theoretical high energy
physics, we find a clear "reverse-visibility" effect, in which articles near
the ends of the lists receive a boost in both short-term readership and
long-term citations, almost comparable in size to the "visibility" effect
documented earlier. For one of those subcommunities, we find an additional
"procrastination" effect, in which last position articles submitted shortly
before the deadline have an even higher citation rate than those that land more
accidentally in that position. We consider and eliminate geographic effects as
responsible for the above, and speculate on other possible causes, including
"oblivious" and "nightowl" effects.
