The legend for a source case listing of variables/influences is as follows:

     *xx* Number of Other Variables Directly Influenced By That Variable

     {xx} Type of Relationship (e.g., {+ } is Monotonically Increasing; {-} is Monotonically decreasing)

     [xx] Time Relationship (e.g., [t-2] is a Delay of 2 Time Periods)

               Where the "time period" (e.g., in months) is specified as a variable in the case.

     (xx) Number of Cause-Effect Quesions Answered Possitively (Out of 6)

               1. There is an identifiable agent in X that influences Y?

               2. There is a close spatial proximity between X and Y?

               3. There is a close time proximity between X and Y?

               4. X (or its anticipation) occurs before Y?

               5. When X is manipulated, all else constant, Y changes?

               6. Some kind of "energy" is transfered from X to Y?

     <C>  Catalyst (Affects the Reaction Time of the Relationship)
