For experience merely accumulates random representations; instruction helps the person to analyze, organize and combine these "formless fragments" (Weiss 1928: 200).[76] By the same token, mere everyday contact with others does not produce empathy.
In practice, the sampling schemes of many genetic association studies involve various types of selection and thus the samples collected are no longer random representations of the corresponding populations.
Two approaches have been used to model the randomness of the column capacity: (1) calibrated Cubic Rankine Gordon curve (CRG) approach with random representation of σc and E∗ and (2) column capacity distribution fitting.
Since our glycan related genes represented 1.5% of the total unique Affymetrix U133 Plus 2.0 targets, random representation of glycogenes predicts a corresponding 1.5% representation of glycogenes (or 23 genes) among those that changed expression.
For this purpose, we analyzed the ESTs data set, assumed to constitute a random representation of the transcribed OR repertoire.
Although the main DEARS protocol sampled a random representation of the local residents, the findings from this substudy may not generalize to the entire population.
It has been shown that even when individuals are sampled at random, this process may not result in a random representation of their contacts, and consequently overall network properties [ 1, 2, 37].
The genomic k-mers distribution and CpG rate of C. cardunculus, compared with data derived from three whole genome-sequenced dicots species, provided a further evidence of the random representation of the C. cardunculus genome generated by RAD sampling.
Altogether, our data suggest that the RAD procedure, despite its use of GC-rich recognition sites, has produced a random representation of the C. cardunculus genome, and shows that it represents a reliable means of assessing genome complexity.
Therefore the expected background representation ratio, or the random representation ratio for G1 within G2 is, and the observed representation ratio for G1 within G2 is, EF is then defined as, with a value for EF > 1 indicating higher than background representation ratio for G1 within G2.
In contrast, gene densities in Triticeae genomes (most notably barley and wheat) have been reported to be much higher (1 gene per 9 kb [ 58] and 1 gene per 4-5 kb [ 19]), possibly reflecting the initial targeting of important agronomic genes in distal regions of chromosomes [ 59] rather than a random representation of the genome sequence.
