         •  The  specificatory  or  case-specific  knowledge  base  S  (obtained  through ex-
         perience  with the specific situation).
         Thus,  !?C= § U S represents the total  physical  knowledge  available.


         COMMENT 3.1 : Fo r modern   geostatisticians   i t would   b e an ostrich-like



        policy  to ignore the  significance  of   these knowledge bases.  It  has   been argued
         that spatial   correlation   models   (belonging  to  the   §   base)   constitute   one  of

         the most   consequential   steps   of   any   geo  statisticalstudy,   the   rest   is   well-



         known calculus   (Journel,   1989).   This   being   the   case,   it   makes   no   sense

         to leave   out   of   the   mapping   process   other   important   Q   and   S   knowledge

         bases (physical   laws,   local   theories,   empirical   relationships,   uncertain   ob-

         servations, etc.),  and   restrict   analysis   to   only   the   usually   limited   amount
         of exact   measurements   available.

             Among the  most significant developments in the frontier of  research  nowa-
        days  is that  a vast  body  of  knowledge  is  becoming available  as a  result  of  a
         new horizontal  integration  among disparate scientific  disciplines.  The  realiza-
        tion  on  the  part  of  many  researchers  that  the  problems  they  are confronted
        with  are  shared  by  other  researchers  in  disparate  fields  leads  to  new  highly
         interdisciplinary  knowledge bases.

         EXAMPLE  3.1:  Figure  3.1  shows  an  integration  framework  of  a  subsurface
        contamination  scenario  with  its  health,  ecologic,  and economic  consequences.
        Various biomedical and non-biomedical fields  are involved in this framework, in-
        cluding biology, toxicology, epidemiology, medicine, Earth sciences, engineering,
        ecology, economics,  and management.  The framework emphasizes the  need for
