En medievärld i förändring och ett ökat individuellt ansvar för sökning, värdering och sammanställning av information i skolan väcker frågor om hur elever, lärare, skolbibliotekarier och deltagare i sociala medier hanterar källkritiska frågor och trovärdighet. I våra studier av klassrumsaktiviteter och av deltagande i Wikipedia framkommer en komplex relation mellan preferenser för förhandsgranskad
In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this “chemic
This thesis is a study of the mountain vegetation in the Faroe Islands based on five altitudinal transects sampled during the period 1999-2001. The vegetation was studied on the basis of plant communities, life-forms and biodiversity of vascular plant species and is discussed in a climate change perspective. The boundary between arctic and temperate vegetation is established and the tolerance of c
MAX-lab is replacing its microtron injector with a RF-gun driven 500 MeV recirculator linac (250 MeV linac with one recirculation). The linac will later be equipped with a low emittance laser gun. In this paper, a future installation of a superconducting undulator driven by the recirculator beam is discussed. The undulator is characterised by the emission of spontaneous undulator radiation. The li
Natural radiative lifetimes have been determined in the determined in the 3 sns 1S0 (n=4-15) and the 3 snd 1D2 (n=3-15) sequences of Mg I employing a pulsed-laser system. The radiative lifetimes in the 1S0 sequence and of the higher members in the 1D2 sequence are unperturbed and scale as (n*)2.6 (where n* is the effective principal quantum number), while the lifetimes of the lower members in the

Abstract in Swedish Denna rapport presenterar och kommenterar den svenska delen av den expertundersökning som gjordes hösten 2007 för att få en bild av hur arbetsmarknadsrelationerna (industrial relations) i EU25- och G7-länderna kan tänkas se ut år 2025. Bakom undersökningen står European Foundation for the Improvement of Living and Working Conditions (Eurofound), som är ett EU-organ specialiseraThis report presents and comments on the Swedish part of a survey made in autumn 2007 to obtain expert opinions on industrial relations in the EU25 and G7 countries in the year 2025. The survey was carried out by the European Foundation for the Improvement of Living and Working Conditions (Eurofound). One of the basic questions was about how the process of globalisation will influence future indus
