Observation sentences are those that are most directly tied to our immediate sensory experience; given the right sensory experience, all competent observers fluent in our language will unhesitatingly assent to the appropriate observation sentence.
In order to be an observation sentence, he said, a sentence must be contingently true or false, and such that competent speakers of the relevant language can quickly and unanimously decide whether to accept or reject it on the basis what happens when they look, listen, etc. in the appropriate way under the appropriate observation conditions (Feyerabend 1959, 18ff).
Both answers are possible by using the results of an advanced numerical model, together with appropriate observations.
Where appropriate, observations made in regards to these gabrb3 null mice will be correlated and contrasted with those observed in autism spectrum disorder (ASD) and/or Asperger syndrome (AS).
For example, the 2007 National Confidential Enquiry into Patient Outcome and Death report [ 54] noted that 'not only are appropriate observations performed less often than is desirable, when they are performed, their frequency is inappropriately low in a significant proportion of patients'.
If appropriate observations are available, then inversion methods for data assimilation can be used to refine the estimates of the source term (e.g. Stohl et al. 2011; Bursik et al. 2012; Denlinger et al. 2012; Kristiansen et al. 2012; Webster et al. 2012).
Its two-dimensional (2-D) horizontal shape, however, has long remained ambiguous due to the lack of appropriate observation instruments.
At this time, changes in vigilance occur, requiring the implementation of systematic evaluation based on the use of an appropriate observation scale.
Thus, our data show that both the appropriate age and an appropriate observation period are required in order to detect plaque growth.
However, the risk-benefit ratio of multiple diagnostic procedures was considered and we included patients who we were confident of the final diagnosis based on appropriate observation or treatment.
