An intensive conservation effort to recover North American Whooping Crane populations, following their near-extinction over the last century, is providing some valuable insight on the question.
Characterization of the risk of recurrent episodes may also bring valuable insight to the question of whether or not to include patients with multiple reports of the disease in risk factor analyses.
In addition to the construction of an efficient, sparse and interpretable classifier, our feature-selection methodology leads to valuable insights into the question of which features are best suited for the discrimination of artifactual and neuronal source components.
The problem is that judgment calls, like 'work harder' and the search for magic secrets stop short of the really valuable questions, the ones that really could make a difference in finding work.

Methods, then, should be viewed not in terms of a hierarchy of intrinsic worth but as valuable only relative to the question asked.
Moreover, such data is valuable with respect to the question of allocation of overall health care resources, especially as radiology is a costly discipline, and expenditure on radiology is steadily increasing [ 8].
