Investigations into the partial frequencies of 2752 bells, both bronze and steel, of a wide variety of dates, founders and sizes, show a simple and unexpec...

We have considerably less control over the structure of the data than in the past and must efficiently operate ...

The mother lode of criminal responsibility scholarship is a unitary theory of criminal excuses, that is, a persuasive normative account of why the criminal law adjudges actors to be blameless despite their having engaged in prohibited conduct.

In two widely cited papers, Meyer et al. have claimed that the power model they derived from their celebrated stochastic optimized-submovement theory encompasses the logarithmic model as a limiting case. We show that Meyer et al.’s theory implies in fact a quasi-lo...
