Properties sometimes attributed to the “particle” aspect of a neutron, e.g., mass and magnetic moment, cannot straightforwardly be regarded in the Bohm interpretation of quantum mechanics as localized at the hypothetical position of the particle. This is shown by examining a series of effects in neutron interferometry. A related thought-experiment also provides a variation of a recent demonstration that which-way detectors can appear to behave anomolously in the Bohm theory.

J. S. Bell's classic 1966 review paper on the foundations of quantum mechanics led directly to the Bell nonlocality theorem. It is not widely appreciated that the review paper contained the basic ingredients needed for a nonlocality result which holds in certain situations where the Bell inequality is not violated. We present in this paper a systematic formulation and evaluation of an argument due to Stairs in 1983, which establishes a nonlocality result based on the Bell-Kochen-Specker “paradox” in quantum mechanics.

Open peer commentary on the article “The Autopoiesis of Social Systems and its Criticisms” by Hugo Cadenas & Marcelo Arnold. Upshot: I discuss the foundations of what I have said in my work as a biologist on autopoiesis, molecular autopoietic systems and social systems. I argue that the theme of sociology should be to understand how is it that we come out of the social manner of living that is the foundation of our origin as languaging and reflecting human beings.

Objective Recent legislation mandating the inclusion of children in clinical trials has resulted in an increase in the number of children participating in research. We reviewed the literature regarding the reasons parents chose to accept or decline an invitation to enrol their children in clinical research. Methods We searched for qualitative studies, written in the English language that considered the experiences of parents who had been invited to enrol their children in research. SCOPUS and Web of Knowledge electronic databases and (...) reference lists of retrieved articles and review papers were searched. Retrieved articles were synthesised using the narrative synthesis method. Results 16 qualitative studies exploring the experiences of parents living in five countries whose children had a range of health conditions of varying severity were included. The health status of the child appeared to influence parents' reasons for participation. Parents whose children had life threatening conditions often considered they had no choice but to participate and many welcomed the innovation offered through research participation. Such parents also viewed the risks of research less negatively than those whose children were healthy or in the stable stage of a chronic condition. This raises questions regarding the voluntariness of informed consent by such parents. Conclusions A tailored approach is needed when discussing research participation with parents of eligible children. While parents of healthy children may be more open to discussions of altruism, those whose children have life threatening illnesses should be given adequate information about the alternatives to, and risks of, research participation.
