Detta är slutrapporten från vår undersökning av psykiska konsekvenser för lokförare av de påkörningar de varit med om på järnvägsspåren. Tidigare har det publicerats tre delrapporter i projektet (Briem, de Lima & Siotis, 2004; Briem, Siotis & de Lima, 2007a, 2007b), och resultaten pekar entydigt i samma riktning. De indikerar att dödsolyckorna på järnvägsspåren har långvariga och ofta svår

A bootstrapping technique for passive mixers has been implemented in a fully integrated 1V CMOS front-end. The idea is to improve the linearity of the mixer by making the switching instants independent of the IF output signal. The technique reduces the intermodulation distortion without degradation of the conversion gain or the noise figure. The measured IIP3 of the front-end was increased by 5 dB

This thesis concerns quantitative genetic aspects of the conservation biology of two rare plants, Scabiosa canescens and Silene diclinis. Particular attention was given to the effects of genetic drift on the structuring of variation in allozymes and quantitative characters, the association between (current) population size and quantitative genetic variation, the level of inbreeding depression in f

Den dokumentvillkorade garantin, som i praktiken vanligen betecknas som självständig, känneteck-nas av att villkoren i utfästelsen väsentligen endast innefattar villkor som refererar till att vissa angivna dokument presenteras för garanten. Dokumentvillkorade garantier förekommer vanligtvis i avtalsstrukturer som involverar ett flertal olika avtal och parter. De typer av avtal som omfattas av sådaDocumentary guarantees, in practice usually described as independent guarantees, are characterized by the fact that they essentially contain only conditions referring to whether or not certain specified documents are presented to the guarantor. A documentary guarantee is usually only one part of a contractual structure involving several contracts and parties. Such contracts give rise to special le

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
