1 Emotional abuse of a child is evidenced by severe anxiety, depression, withdrawal or improper aggressive behavior as diagnosed by a medical doctor or psychologist, and caused by the acts or omissions of the parent or caretaker.  Exploitation means use of a child by a parent, guardian or custodian for material gain.
1 Introduction The Lanczos method [15] is widely used for ï¬nding a small number of extreme eigenval-ues and their associated eigenvectors of a symmetric matrix (or Hermitian matrix in thecomplex case).6.9)This bound, too, could be much bigger than the one of (5.1) because of one or more Î¶ j with k â i Ä j Ä â are much bigger than Î¶ i. 7 Numerical examples In this section, we shall numerically test the eï¬ectiveness of our upper bounds on theconvergence of the block Lanczos method in the case of a cluster.
In particular, this method can be applied when the right and left starting blocks have different sizes, a situation that often arises in reduced-order modeling of linear dynamical systems, a topic closely related to matrix eigenvalue problems.

As a general thrust, block algorithms substitute matrix block multiplies and block solvers for matrix-vector products and simple solvers in unblocked algorithms.
