long long time, so unless there is some compelling evidence of
an environmental |
| influence the
history of autism spectrum disabilities (if they could have
been accurately |
| diagnosed)
is not usually pursued. Similarly, where and when AIDS viruses
might have crossed |
| from other
primates to humans is not really useful knowledge - there is
an acknowledged |
| epidemic and the
priority is to limit the human deaths and damage. With
communicable |
| diseases like
Lassa fever, Ebola and AIDS one can usually assume that the
epidemic will spread |
| by following
lines of human movement. This tends to mean along roads,
sometimes along rivers |
| and even by air.
In the case of disease like malaria which has a vector of
mosquitoes there are |
| usually
limits imposed by large bodies of water (oceans), mountain
ranges and deserts. SAITO |
| rather
arbitrarily assumes that the frequency of genetic expression
of disabilities of interest is |
| constant. SAITO
has borrowed old code that was used to plan medical clinic
locations for |
| diseases like
Lassa fever, Ebola and AIDS. That code abused the intractable
Navier-Stokes |
| equations, more
commonly encountered in explosions and tsunamis, to suggest
when to build |
| where to build
clinics ahead of the spread of the disease such that patient
travel distance was |
| mimimzed. The
objectives were to lighten the logistics burden on already
sick people and to |
| reduce the
possibility of spreading the epidemic. For people with special
needs the Wyoming |
| challenge is to
locate economically viable schools (= enough students to cover
rent and utilities |
| and pay a
teacher) without obligating the students to drive 100 miles
through a blizzard often. |
