background: in the process of cancer treatment, mothers of children with cancer experience burden of care as a result of these conditions. early detection of burden of care has an important role in promoting health care. the aim of this study was to evaluate burden of care in mothers of children with a malignancy. materials and methods: this cross sectional study was done on 70 mothers of child...

In ‘Corroborating Testimony, Probability and Surprise’, Erik J. Olsson ascribes to L. Jonathan Cohen the claims that if two witnesses provide us with the same information, then the less probable the information is, the more confident we may be that the information is true (C), and the stronger the information is corroborated (C*). We question whether Cohen intends anything like claims (C) and (...

The problem of demonstrating entanglement is central to quantum information processing applications. Resorting to standard entanglement witnesses requires one to perfectly trust the implementation of the measurements to be performed on the entangled state, which may be an unjustified assumption. Inspired by the recent work of F. Buscemi [Phys. Rev. Lett. 108, 200401 (2012)], we introduce the co...

Dimension witnesses allow one to test the dimension of an unknown physical system in a device-independent manner, that is, without placing assumptions about the functioning of the devices used in the experiment. Here we present simple and general dimension witnesses for quantum systems of arbitrary Hilbert space dimension. Our approach is deeply connected to the problem of quantum state discrim...

In England and Wales, in accordance with the adversarial principle of orality, witnesses in criminal proceedings are generally required to give evidence ‘live’ in open court. It is, nevertheless, now widely accepted that this obligation can place onerous demands on witnesses and militates against receipt of the best evidence potentially available in some cases. For victims of rape, the process ...

Throughout this paper PJ Kearney attempts to balance the risks and benefits of different approaches in paediatric oncology. Decisions have to be considered both in the short and the long term. Where religious beliefs, such as those held by Jehovah's Witnesses in relation to blood transfusions, conflict with normal medical practice the decision is often removed from the doctor, parents or patien...
