In a perturbative QCD approach, with inclusion of spin and transverse momentum effects, experimental data on azimuthal asymmetries observed in polarized semiinclusive deeply inelastic scattering and e{sup +}e{sup -} annihilations can be used to determine the Sivers, transversity, and Collins soft functions. By using these functions, within the same scheme, we predict p{sup {up_arrow}}p{yields}h+X single spin asymmetries in remarkable agreement with high energy experimental data.
