In this paper, we present a novel system which automat-ically converts text documents into XML by using machine-learningtechniques. In the first phase, the system uses the Self-OrganizingMap (SOM) algorithm to arrange marked-up documents on a two-dimensional map such that the documents similar in content appearcloser to each other. In the second phase, it then uses the induc...

Non-Compliance and Instrumental Variables in Behavioural Medicine: a Commentary on van Dongen et al.

The paper by van Dongen et al. [1] in this issue is to be commended on many levels. It contributes substantially to the blood donor recruitment and mere-measurement literatures and highlights the importance of replication. Importantly, it opens up the debate on the causes and consequences of non-compliance in randomised controlled trials (RCTs) in behav-ioural medicine. Non-compliance introduce...

The Socratic Bergson

2-adrenoceptors are essential presynaptic regulators of norepinephrine release from sympathetic nerves. Previous studies in mice with targeted deletions in the 3 2-adrenoceptor genes have indicated that these receptors are essential for embryonic development. In the present study, we searched for the 2-adrenoceptor subtype(s) involved in placental development and its molecular mechanism using m...
