From Probation Journal This study suggests that economists have a unique opportunity to help solve the prison crisis by bringing sophisticated economic modelling techniques to bear on the problem. Over the last decade prison numbers risen sharply in England and Wales and are set to rise further. As of January 2010 the prison population was [...]... Read more »

I’m a contrarian. Majority consensus makes me shudder. I just like rooting for underdogs*. Those undersea ridges at the boundaries of tectonic plates, spewing molten magma to form new crust are o’ so popular these days.

I was talking to a Reuters reporter the other day and learned of a new acupuncture study out of China, this one about amblyopia, or “lazy eye”. Amblyopia is a common and interesting visual problem.

If religion is a virus, then perhaps the spread of religion can be understood through the lens of evolutionary theory. Perhaps cultural evolution can be modelled using the same mathematical tools applied to genetic evolution.
Well, that's overly simplistic, of course - as anyone who's followed the 'meme' controversy over the years will know. In fact, the authors of the paper I'm writing up today - Michael Doebli and Iaroslav Ispolatov at the University of British Columbia - studiously avo........ Read more »

Clinical neuroscience conditions represent a heterogeneous group of conditions with varying contributions from genetic and environmental influences. It has been common to view some of these conditions under the disease model presumed to represent a specific pathophysiology, tissue pathology (i.e. Alzheimer’s disease, Huntington’s disease). Other conditions have been classified as representing primarily a disorder of behavior (i.e. anorexia nevosa, substance use disorders).The dis........ Read more »

It seems sensible and seductive to suggest that child abuse causes mental disorder and that mental disorder aggravates the risk for male suicide. However, contrary to what Mandelli et al. (2010) might argue here, I would protest that attempting to squeeze such a multi-faceted and fluid problematic into a thimble is a circus trick beyond reason. ... Read more »

This article reminds me of the last time I spent 2 years obstinately trying to prove a point! Why?

... and what to do about it.
Decisions within a company are not made on pure rational grounds. Assuming that there is the will to make a rational decision, nevertheless limits in information gathering, computing capabilities and memory lead to irrational conclusions (bounded rationality).
So the goal must be to enhance rational decision making and for this end Kaufmann et al. (2009) developed a framework to combat irrationality.
The authors use case studies to analyze companie........ Read more »

Today, the Royal Society published my article reviewing the invertebrate data supporting a scientific concept of free will. In it, I first reiterate that the metaphysical concept of free will is long dead (since the 1970s). Then I emphasize that determinism has been dead for even longer (basically since quantum mechanics). Finally, I propose that the ability to behave differently in identical circumstances forms the basis for a scientific concept of free will. Basically, IMHO, free will is a bi........ Read more »

Following this year’s Nobel prize in physics to Andre Geim and Konstantin Novoselov, the relevance of graphene hardly needs to be stated. Graphene-based devices have a real potential owing to the material’s unique electronic properties. If graphene, which is metallic, is cut into small pieces it becomes semiconducting and could be used as a transistor. [...]... Read more »
With the rapid expansion of next-generation sequencing, there has been speculation that the backbone technology of older genomic sequencing, large-insert cloning (e.g., using bacterial artificial chromosomes [BACs]) would become less important. However, in many laboratories, BAC libraries still play a role in sequencing and gene expression studies.
In a recent study, Okada et al. screened a library created in the CopyControl™ BAC Cloning Kit (Hind III cloning-ready vector) to study the mechan........ Read more »
