Calling Time on Digital Clocks

I explore two logical possibilities for the discretization of time, termed “instantaneous” and “smeared”. These are found by discretizing a continuous theory, and the resulting structure of configuration space and velocities are described. It is shown that results known in numerical methods for integration of dynamical systems preclude the existence of a system with fixed discrete time step whi...

Calling Recessions in Real Time*

This paper surveys efforts to automate the dating of business cycle turning points. Doing this on a real time, out-of-sample basis is a bigger challenge than many academics might presume due to factors such as data revisions and changes in economic relationships over time. The paper stresses the value of both simulated real-time analysis— looking at what the inference of a proposed model would ...

Calling time on the 10-minute consultation [letter].

Detection is unsophisticated and currently inadequate; the guidance that 3 months is enough is not good enough and draws parallels with hypertension detection. Current evidence on intervention and effectiveness seems very light. I have asked everyone (including this journal) to provide me with a NNT for a patient with CKD III who need detecting and intervening with to prevent either a cardiovas...

Well past midnight: Calling time on implicit invariant learning?

Three experiments are reported that examine the nature of knowledge underlying performance in the invariant learning task. Previous research (Bright & Burton, 1994; McGeorge & Burton, 1990) has supported an account of performance based on the implicit abstraction and application of a rule pertaining to the invariant feature. In contrast, we found effects in both the digit and clock invariant ta...
