Standard superspace Feynman diagram rules give one estimate of the onset ofultraviolet divergences in supergravity and super Yang-Mills theories. Newertechniques motivated by string theory but which also make essential use ofunitarity cutting rules give another in certain cases. We trace the differenceto the treatment of higher-dimensional gauge invariance in supersymmetrictheories that can be dimensionally oxidized to pure supersymmetric gaugetheories.
