2011 December 16, Denis Campbell, “Hospital staff 'lack skills to cope with dementia patients'”, in Guardian:
- "This shocking report proves once again that we urgently need a radical shake-up of hospital care," said Jeremy Hughes, chief executive of the Alzheimer's Society. "Given that people with dementia occupy a quarter of hospital beds and that many leave in worse health than when they were admitted, it is unacceptable that training in dementia care is not the norm."
2013 June 22, “Engineers of a different kind”, in The Economist, volume 407, number 8841, page 70:
- Private-equity nabobs bristle at being dubbed mere financiers. […] Much of their pleading is public-relations bluster. Clever financial ploys are what have made billionaires of the industry’s veterans. “Operational improvement” in a portfolio company has often meant little more than promising colossal bonuses to sitting chief executives if they meet ambitious growth targets. That model is still prevalent today.
