His conclusion was that icing probably worked, but its effect is mostly noticeable only on kicks of reasonable difficulty, say from 40 to 55 yards.
Precision, a lovely surface, a reasonable level of difficulty, and an audible chuckle when illumination dawns.
To humans, the TOL offers a familiar physical model (balls and pegs) and a reasonable gradation of difficulty.
To address this difficulty, a reasonable solution could be pre-selection of a small number of SNPs, followed by modeling of associations between these SNPs and the phenotype [ 4].
(Neutral was included to maintain a reasonable level of task difficulty, i.e. to minimize subjects performing the task using only one feature, e.g. 'happy' or 'not happy' using the wide open mouth; see also Smith et al., 2008).
However, both dialects of CIF share a common syntax, so that many tools can handle both without any difficulty, and a reasonable degree of interoperability still exists.
Since response rates can be low for GPs [ 27] responding to surveys, difficulties achieving a reasonable response rate were anticipated in planning and sample size calculation.
Bearing in mind likely difficulties achieving a reasonable response rate, perhaps it is not surprising that a majority of our respondents was positive about the use of referral guidelines.
We ensured that rigorous and comprehensive processes of questionnaire design, piloting and administration were undertaken, but a brief scoping exercise exploring approaches to surveying GPs indicates that difficulties achieving a reasonable response rate should be expected [ 33].
The moderate correlations between physician-rated ADHD symptoms on the ADHD rating scale and the GIPD indicate a reasonable discriminant validity of the difficulties and the impairment of the child in different settings throughout the day as assessed by the GIPD scale on the one hand and the ADHD-RS on the other.
