I commented in an Editorial last year on the importance for academic journals of citations and impact factors (Trayhurn, 2002). I noted that a number of articles published by the BJN over the 50þ years of our existence have been very highly cited, the article receiving most citations being that of Durnin & Rahaman (1967). This paper, which has received over 700 citations, was reproduced in the ...

T he aphorism Publish or perish usually applies to individual investigators whose scientific careers are closely linked to their production in terms of papers in high quality journals. I will try to show that – mutatis mutandis – it applies equally to journals themselves. There are many ways of calculating journal impact, most of which are based on reference counting. The most popular ranking p...

The physical nature of Psi phenomena such as telepathy is an important problem in the life information science. Scientists have confirmed the existence of telepathy phenomena through many strict experiments. Then can modern science (e.g. quantum theory) provide a scientific explanation for telepathy phenomena? In this paper, we will seek the possible quantum nature of telepathy from both theore...
