Mr. Callahan's policy allowed for diversification so that if, for example, a particular business was about to close, its failure would not bring down the credit union.
We hypothesize that evolution of grazing bilaterians prior to 555 Ma caused perturbations in sediment stability and DOC concentrations, which limited competitive exclusion and allowed for diversification of Ediacara-type organisms, as exemplified by fossils in the taxonomically and ecologically rich localities of the White Sea assemblage.
In turn, this allows for diversification of the proteome without a corresponding increase in the number of protein-coding genes [ 65].
First, the selection regime that historically allowed for diversification along environmental gradients needs to be restored (e.g., habitat restoration, re-installation of ecotones: (Smith et al. 1996; Collyer et al. 2007).
Candidate effectors identified in this study showed no sign of positive selection as no substitution mutation was found [ω (dN/dS) < 1], which is consistent with the view that partial resistance may not impose enough selection pressure on pathogen populations to allow for diversification and novel races to emerge [ 44].
Of course, we acknowledge that the rodent phylogeny here presented has to be ameliorated because of the suboptimal gene and taxon coverage, but we really think it is a reasonable approximation of the rodent phylogeny which accuracy is sufficient to allow for diversification analyses.
There is no point in diversifying if the investment does not offer a genuinely different source of return (much of private equity falls into this category) or if the asset is already overvalued.Yet even allowing for this, diversification has surely not offered the benefits most pension funds expected.
As a result, these stocks' fundamentals play a larger and more important role in their pricing, producing returns less dependent on those of other securities, and allowing for greater diversification in investors' portfolios.
