Can scientific quality be quantified?
" … The first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is o...
متن کاملCan latent speech quality dimensions be quantified directly?
Previous studies revealed that the quality of transmitted speech can well be described by three perceptual dimensions: “discontinuity”, “noisiness”, and “coloration”. In this paper, a method is presented for quantifying these dimensions directly in subjective tests. Two experiments were conducted according to this method with large sets of test conditions. A detailed description of the test pro...
متن کاملThe immobilisation of chiral organocatalysts on magnetic nanoparticles: the support particle cannot always be considered inert.
A systematic study concerning the immobilisation onto magnetic nanoparticles of three useful classes of chiral organocatalyst which rely on a confluence of weak, easily perturbed van der Waals and hydrogen bonding interactions to promote enantioselective reactions has been undertaken for the first time. The catalysts were evaluated in three different synthetically useful reaction classes: the k...
متن کاملEstimation of Lifetime Reproductive Success when reproductive status cannot always be assessed
The Lifetime Reproductive Success (LRS) of an individual i.e. the number of young raised during its lifespan is an indicator of its contribution to future generations and thus a measure of fitness. Nevertheless, the LRS is hard to estimate because of the difficulty to keep track of the outcome of each breeding attempt (successful or failed and, if successful, number of young raised). We propose...
متن کاملWhy Machines Cannot be
Mental processes are abstracted from a subset of the physical universe ; these, in turn, lead to the world of ideas. Although these ideas include quantum logic, no credible way has yet been found that constructs machines which use superimposed possibilities in the style of quantum logic, more general in computing power to machines based on classical logic. Machine theories are based exclusively...
