DESCRIPTION:We present two applications of the (rather formal) Hawking qua
 silocal mass construct to cosmology. We first apply it to simulations of l
 arge scale structures\, which are\nNewtonian even though the size of the b
 ox used exceeds the Hubble radius. The Hawking mass splits into a ``Newton
 ian'' part due to local perturbations and a\n``relativistic'' part due to 
 the cosmological background. The Newtonian part quickly dominates over the
  relativistic one during evolution\, supporting the validity of Newtonian\
 nsimulations. The same splitting is applied to the turnaround radius of a 
 large object in the accelerated era\, introducing a small correction and a
  clarification of the ``mass'' concept used in previous literature.
