  We study a very specific type of neutrino mass and mixing structure based on
the idea of Strong Scaling Ansatz (SSA) where the ratios of neutrino mass
matrix elements belonging to two different columns are equal. There are three
such possibilities, all of which are disfavored by the latest neutrino
oscillation data. We focus on the specific scenario which predicts vanishing
reactor mixing angle $\theta_{13}$ and inverted hierarchy with vanishing
lightest neutrino mass. Motivated by several recent attempts to explain
non-zero $\theta_{13}$ by incorporating corrections to a leading order neutrino
mass or mixing matrix giving $\theta_{13}=0$, here we study the origin of
non-zero $\theta_{13}$ as well as leptonic Dirac CP phase $\delta_{CP}$ by
incorporating two different corrections to scaling neutrino mass and mixing:
one where type II seesaw acts as a correction to scaling neutrino mass matrix
and the other with charged lepton correction to scaling neutrino mixing.
Although scaling neutrino mass matrix originating from type I seesaw predicts
inverted hierarchy, the total neutrino mass matrix after type II seesaw
correction can give rise to either normal or inverted hierarchy. However,
charged lepton corrections do not disturb the inverted hierarchy prediction of
scaling neutrino mass matrix. We further discriminate between neutrino
hierarchies, different choices of lightest neutrino mass and Dirac CP phase by
calculating baryon asymmetry and comparing with the observations made by the
Planck experiment.
