More than 70 different psychological tests or batteries of tests could be identified in these studies. The tentative conclusions that can be drawn are as follows. Monoamine oxidase (MAO) inhibitors hardly influence cognitive performance.(More)
We present a one-loop calculation of a gauge invariant QCD beta function. Using both momentum and temperature renormalization group equations we investigate the running coupling in the magnetic sector as a function of temperature and momentum scale. At fixed momentum scale we find that, in contrast to λφ 4 or QED, high-temperature QCD is strongly coupled,(More)

From cultural-historical and socio-cultural perspectives, this assumption is problematic because scientific practices are(More)
