  By remaining strictly within the confines of QCD, i.e., {\it without}
invoking the parton model or any other exogenous element, we identify and resum
perturbatively to leading order, along with a correction term, enhanced
radiative gluon contributions to the Drell-Yan type ($q\bar{q}$ pair
annihilation) and deep-inelastic-scattering type ($eq\to eq+X$) cross-sections.
The key feature of the adopted approach is the recasting of QCD in terms of a
space-time mode of description, which employs a path-integral formulation of
field theories, as originally implied in works of Fock, Feynman and Schwinger.
