The very first step to start psychophysical experiments

From OpenMP to MPI: first experiments of the STEP source-to-source transformation tool

The STEP tool allows source-to-source transformation of programs, from OpenMP to MPI, for execution on distributed-memory platforms. This paper describes tests of STEP on popular benchmarks, and analyses the results. These experiments provide both encouraging feedback and directions for improvement of the tool.

First Step to Independence

The step out of mental hospital back into the community can he a major ordeal for many patients. To provide a halfway stage between hospital and full independence, the Birmingham and District Association for Mental Health recently opened a special short-stay hostel for ex-patients, which is described here by Julian Smithells. In many mental hospitals today there are patients who are ready to ta...

Estimation of Separable Representations in Psychophysical Experiments

Studying how individuals compare two given quantitative stimuli, say d1 and d2, is a fundamental problem. One very common way to address it is through ratio magnitude estimation, that is to ask individuals not to give values to d1 and d2 but rather to give their estimates of the ratio p = d1/d2. Several psychophysical theories (the most known being Stevens’ power-law) claim that this ratio cann...

Awareness: the first step to action.

Humans have the greatest capacity for foresight but the least inclination to use it. Although 35% of Americans say that they or someone close to them have had a stroke, only 1% worry about it. The statistics resulted from a telephone survey of 1000 adults representative of the US demographics conducted by the American Heart Association.1 Moreover, only a minority know what to do to prevent a st...
