[Sigmetrics] Fw: Re: [scisip] China surpassing US in publications PS

[Pamela Sieving]

Thanks, Loet.  Can you tell us how the figures were determined?  I'm
working on a project looking at the output of Asian countries (in
ophthalmic genetics, so a subset) and it's clear that Chinese vision
researchers are dramatically increasing their productivity in recent
years.  However, most of the work is done by collaborative groups in more
than one country, so I'm curious about your numbers.

Thanks,

Pam

-----
But yield who will to their separation,
My object in living is to unite
My avocation and my vocation
As my two eyes make one in sight.
Only where love and need are one,
And the work is play for mortal stakes,
Is the deed ever really done
For Heaven and the future's sakes.
    (Robert Frost:  Two Tramps in Mud Time)
