"Thousands of our men are getting practically nothing at all to do"

All or Nothing at All

We continue a study of unconditionally secure all-or-nothing transforms (AONT) begun in [12]. An AONT is a bijective mapping that constructs s outputs from s inputs. We consider the security of t inputs, when s − t outputs are known. Previous work concerned the case t = 1; here we consider the problem for general t, focussing on the case t = 2. We investigate constructions of binary matrices fo...

Are we getting our money's worth?

Getting something out of nothing

We study quantum key distribution with standard weak coherent states and show, rather counter-intuitively, that the detection events originated from vacua can contribute to secure key generation rate, over and above the best prior art result. Our proof is based on a communication complexity/quantum memory argument.

The master's apprentices- making best practice out of practically nothing!

The Paediatric Unit at Flinders Medical Centre in South Australia caters for children aged between 0 18 years of age, within a large general metropolitan hospital. Consistent with national trends we have experienced a significant increase in adolescents admitted with an eating disorder. In response a core eating disorder group visited other hospitals within the Room: State and interRoom: State ...

All It Takes for Corruption in Health Systems to Triumph, Is Good People Who Do Nothing; Comment on “We Need to Talk About Corruption in Health Systems”

Numerous investigations demonstrate that the problem of corruption in the health sector is enormous and has grave negative consequences for patients. Nevertheless, the problem of corruption in health systems is far from eminent in the international health policy debate. Hutchinson, Balabanova, and McKee have identifed in their Editorial five reasons why the health policy community has been relu...
