However, the ability of these instruments to change attitudes toward conservation and their efficacy in affecting water use remains poorly understood.
Two other canonical site types, each associated with weaker preferential conservation and much lower efficacy (Friedman et al., 2009), are the 6mer (position 2 7 match [ Lewis et al., 2005]) and offset-6mer (position 3 8 match [ Friedman et al., 2009]).
We draw implications for focused educational programs promoting awareness of water conservation issues and monitoring their impacts and efficacy.
"Proving safety and efficacy is needed," she says.
Their consistent belief in the primacy and efficacy of doubt.
On a number of occasions Boyle assures us that "God [is] the Author of the universe & free Establisher of the Laws of motion, whose generall Concourse is necessary to the conservation & Efficacy of every particular Physicall Agent" (BP 2 132).
And safety and efficacy are both doubtful.
Similarly, vaccines have a well-proven safety and efficacy record.
Another study postulates that the safety and efficacy of more extensive hemodilution is controversial because it is not possible for all patients and may provide only little additional blood conservation [ 15].
This study is aimed at determining the suitability of the four-point bending test, a flexural strength test, to evaluate the efficacy of consolidation treatments for plasters, used in the practice of conservation and restoration of ancient buildings.
Most important, conservation should be encouraged, since water conservation results in energy conservation, and vice versa.
