Breakdowns ∗ Godfrey Keller
We study a continuous-time game of strategic experimentation in which the players try to assess the failure rate of some new equipment or technology. Breakdowns occur at the jump times of a Poisson process whose unknown intensity is either high or low. In marked contrast to existing models, we find that the cooperative value function does not exhibit smooth pasting at the efficient cut-off beli...
متن کاملYes Sir, no Sir, not much difference Sir.
OBJECTIVE To assess whether making the sender's knighthood explicit in a series of letters would have any detectable effect on the response. DESIGN A random sequence was generated by flipping a coin to determine whether a letter would have 'Sir Iain Chalmers' or 'Iain Chalmers' typed under the signature.

متن کاملScience fictions: Comment on Godfrey-Smith
This is a comment on Peter Godfrey-Smith’s, ‘‘Models and Fictions in Science’’. The comments explore problems he raises if we treat model systems as fictions in a naturalized and deflationary framework.
متن کاملThe calibration of CT Hounsfield units for radiotherapy treatment planning.
Computer tomographic (CT) scans are used to correct for tissue inhomogeneities in radiotherapy treatment planning. In order to guarantee a precise treatment, it is important to obtain the relationship between CT Hounsfield units and electron densities (or proton stopping powers for proton radiotherapy), which is the basic input for radiotherapy planning systems which consider tissue heterogenei...
