It is argued that evolution goes beyond that which can be described in a well-defined language) and that it instead enforces a language that is itself evolving. Evolution is the unfolding of this self-reference. The unfolding methodology of the logician Alfred Tarski is taken as a basis for the explicability of evolution. Looking at Tarski´s results as a linguistic complementarity, we get a view w

Much information has been gathered through the years from fires in fire investigation reports or as statistics. The information might have been collected centrally by an agency, an insurance company or locally by the local fire service. The information can be used to learn from these events and to improve the fire safety in buildings. In this paper a methodology to find technical deficiencies in f

Philosophers have stressed the need to distinguish between explanatory (motivating) reasons and justifying (good) reasons. The distinction is often illustrated with an example of someone doing something that is intended to appear at the outset as incomprehensible. The next step is then to add some further details about the agent — typically some information about his or her beliefs and desires — p

Results of molecular phylogenetic analysis after nuclear (18S LSU, ITS1/ITS2), mitochondrial (12S and 23S SSU) and chloroplast DNA of lichen-forming fungi, symbiotic and terrestrial algae as well as microscopic filamentous fungi obtained for the first time in Ukraine are compared with recent data on morphology, anatomy and biochemical characters. Taxonomical treatment of several groups of lichen-f

We suggest that the collapsing core of a massive rotating star may fragment to produce two or more compact objects. Their coalescence under gravitational radiation gives the resulting black hole or neutron star a significant kick velocity, which may explain those observed in pulsars. A gamma-ray burst can result only when this kick is small. Thus, only a small fraction of core-collapse supernovae

Popular Abstract in Swedish Sjukdomar hos äldre har ofta annan sjukdomsbild än motsvarande sjukdom hos medelålders och yngre. Till exempel är symtomen är ofta mindre tydliga, äldre har ofta flera samtidiga sjukdomar som ger en komplex sjukdomsbild, dessutom kan ett ”mindre allvarligt” sjukdomstillstånd föra med sig betydande besvär pga annan samtidig sjukdom. Detta gäller även för depressionssjukdStudies have found that depressive states in old age that do not fulfil the criteria for major depression are clinically important depressive states. These depressive states are common in primary care patients. Therefore, studies of late-life depression from a primary care perspective are needed. A depressive rating scale, Hopkins Symptom Checklist-25 (HSCL-25), was used in a community survey in 1
