The way researchers currently assess changes in psychological distress may be wrong and lead to misleading and disappointing results. These are the conclusions of a paper published in the third 2004 issue of Psychotherapy and Psychosomatics by three investigators of the University of Bologna (Giovanni A. Fava, Chiara Ruini and Chiara Rafanelli).
Their conclusions are supported by accompanying editorials by Per Bech (Denmark) Carlo Faravelli (Italy) and Andrew Nierenberg (USA)
Psychometric theory is the basis for the development of assessment instruments in psychiatric research. However, the psychometric model appears to be largely inadequate in the clinical setting because of its lack of sensitivity to change and its quest for homogeneous components.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
