Will we have enough physicians? One of life's "unanswerable" questions.
What appears to be clear is that past studies and projections have produced highly variable and frequently contradictory responses and that past projections have sometimes not even been directionally correct. For example, in the 1970s there was concern that the United States was facing an imminent shortage of physicians. This led to a push to expand the number of both medical schools and studen...
متن کاملHave We Seen Enough Traces?
Dynamic specification mining extracts candidate specifications from logs of execution traces. Existing algorithms differ in the kinds of traces they take as input and in the kinds of candidate specification they present as output. One challenge common to all approaches relates to the faithfulness of the mining results: how can we be confident that the extracted specifications faithfully charact...
متن کاملDo we have enough 'injidents'?
The practice of medicine can never be risk free. Taking risks leads, by definition, to accidents – it is behaviour that carries with it a probability of an adverse outcome. But there are also rewards for risk taking. Reducing risk-taking will reduce both accidents and the rewards: for example, the extremely risk averse regimes governing the development of new drugs increase their costs and dela...
متن کاملHave we tested Lorentz invariance enough?
Motivated by ideas from quantum gravity, Lorentz invariance has undergone many stringent tests over the past decade and passed every one. Since there is no conclusive reason from quantum gravity that the symmetry must be violated at some point we should ask the questions: a) are the existing tests sufficient that the symmetry is already likely exact at the Planck scale? b) Are further tests sim...
متن کاملLibet Do We Have Free Will ?
I have taken an experimental approach to this question. Freely voluntary acts are preceded by a specific electrical change in the brain (the ‘readiness potential’, RP) that begins 550 ms before the act. Human subjects became aware of intention to act 350–400 ms after RP starts, but 200 ms. before the motor act. The volitional process is therefore initiated unconsciously. But the conscious funct...
