- 2013 August 31, “Promotion and self-promotion”, in The Economist, volume 408, number 8851:
- One of academia’s deficiencies is that, though its lecture halls and graduate schools are replete with women, its higher echelons are not. Often, this is seen as a phenomenon specific to the sciences. … In fact, the disparity applies to the whole grove.

Usage notes
[edit]In the context of dietary reference intake amounts for micronutrients, a precise usage distinction is often made whereby deficiency is a separate and more severe category that is coordinate with insufficiency. A common example is a widely used convention for cutoff value of vitamin D level in human blood, which defines less than 30 nanograms per milliliter as insufficient and less than 20 nanograms per milliliter (even worse) as deficient. In broad usage, though, the words are synonymous.
