USA: Treading softly on the ozone layer

Trisomy 13 and 18 and quality of life: treading "softly".

Not too long ago I was privileged to speak at an annual international conference of the Support Organization For Trisomy 18, 13 and Related Disorders (SOFT). I learned much more than I taught. There were over 200 families there. Approximately half of the families were bereaved parents of a child with Trisomy 13 or 18. But then there was the other half, the half with surviving children with a tr...

Softly Focusing On Data

A computational approach providing a focus for unsupervised, reactive, data mining is suggested. In data mining, achieving focus is an important issue. This is because there are too many attributes and values in a real database to consider them all. A soft focus is suggested as both data and the focus product may be imprecise. An approach is suggested for unsupervised search controlled by progr...

The Influence of Treading on Pasture

In 1858 H. S. Thompson, writing in the “Journal of the Royal Agricultural Society”, quoted an ancient Persian proverb, “The sheep has a foot of gold, and turns to gold whatever it touches”, and wrote that, although at first he agreed with the proverb, he rapidly became dissatisfied with it. In his experience-sustained yheavystockifig-w? sheep caused pastures to deteriorate. In my opinion his im...

Tsallis, Dynamical scenario for nonextensive statistical mechanics, Physica A 340 (2004) 1–10] is the best empirical quantifier of nonextensivity.
