No house, no abiding can be certain; therefore his own life is spent as a perpetual passenger, minus a week here and there at inns convenient to the tracks.
The most important amendment is to change the reference years from 2005-2007 to 2004-2006, as the data for 2007 are so new that we cannot be certain of them, and it is therefore better to use the data that we are sure of.
Thirdly it could have been possible that in less clear-cut cases the diagnosis of carpal tunnel syndrome was not certain and therefore steroid injection were less effective (although the scores of the Katz-hand diagram suggest that general practitioners can diagnose carpal tunnel syndrome reliably on clinical grounds).
However for the provinces and autonomous districts, we cannot be certain about the sampling representativeness and therefore we cannot use the samples to estimate the MCH workforces in each of the provinces or autonomous districts.
This is not certain and therefore the balance could in reality be more in favour of the AMS if the preventive effect lasts longer.
We were reliant on nurses being invited to participate in the study by a gate keeper, due to ethical committee requirements, and therefore cannot be certain that every nurse who may have been interested and able to participate received information about the study.
One danger is that this traditional approach leads executives to view uncertainty in a binary way to assume that the world is either certain, and therefore open to precise predictions about the future, or uncertain, and therefore completely unpredictable.
The 2013 Pediatrics article, which studied "excessive" television watching by New Zealand children, noted that "we do not know what programs were viewed and therefore cannot be certain that it is viewing violence that contributes to antisocial behavior".
An audit by the Pentagon's inspector general has found that the Army did a poor job of testing the ballistic plates used in body armor and therefore cannot be certain that the equipment is adequately protecting soldiers.
On the basis of this study we are unable to determine whether these variables are causally related to suicide and therefore cannot be certain of the efficacy of society-wide interventions to reduce suicide rates.
