Andrew Cox (2013) argues that both equally the generic causal variables along with the contextual situations should be thought of when interpreting the reason for the hurt.

four. The properties that happen to be proposed below include things like the “sort, magnitude, path and proximity (e.g. location and elevation)”.

A pattern involves the degree of harm in between different resources and along the same product mirror an analogous intensity/duration of publicity on the byproducts of combustion. As described before, In case the magnitude of damage is altering, however the strains of demarcation are linked, then a sample may still exist.
