Our effectiveness metric can be used in this context to provide an early indicator of the usefulness of a given signature set.
In general, biometric quality is defined as an indicator of the usefulness of the biometric sample for recognition, as illustrated in Figure2.
Fishbein has commented that one good indicator of the usefulness of models such as the TPB is their power to help design effective interventions that produce behavior change (see Conner and Armitage [1998], p1453).
The evaluation finds that the perceived meaning of the indicator does not vary with scale, but in common with all mapped indicators, the usefulness of the indicator, to different user groups, does change with scale of presentation.
While degranulation indices are general indicators of activation, they may have limited usefulness in evaluating specific pathophysiologic relationships.
It's been used to explain everything from indicators of poverty to the (dubious) usefulness of reducing cholesterol in addressing heart disease.
Serum acute phase proteins (APP) Haptoglobin (Hp), Amyloid A (SAA) and Acid Soluble Glycoprotein (ASG) concentrations were also determined to evaluate their usefulness as indicators of clinical status.
However, few studies have tested for statistical differences in the factors that influence the exposure of mammals to WNV, which thus would establish their usefulness as indicators of variation in WNV transmission.
A GPRI score above the cut-off of 50 at baseline was able to predict 84% of 'distress' cases identified by HAM-D or HAM-A, a strong indicator of its potential usefulness in a clinical setting.
