On the role of migration for the distribution of arctic birds - a circumpolar perspective

Popular Abstract in Swedish Om flyttningens betydelse för utbredningsmönster för arktiska fåglar Sara Henningsson Fågelflyttning är en anmärkningsvärt framgångsrik strategi som möjliggör att en större mängd individer kan försörjas genom rörelser mellan olika regioner. Inom dessa olika områden, som ofta ligger mycket långt ifrån varandra, kan fåglarna utnyttja stora säsongsmässigt tillgängliga resFlexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. I studied the circum

Seasonal variations of atmospheric trace gases in the high Arctic at 79 degrees N

Since March 1992 the total column abundances of several tropospheric and stratospheric trace gases have been monitored year-round from the Network for Detection of Stratospheric Change station in Ny Alesund, Spitsbergen (78.9 degrees N, 11,9 degrees E). A groundbased Fourier transform infrared (FTIR) spectrometer performed these measurements using the Sun as a light source during the summer, and t

Photochemical reactions in biological light perception and regulation

Many photochemical reactions involved in the sensing of and regulation by light and ultraviolet radiation by organisms consist of cis-trans (and trans-cis) isomerisations. This chapter starts with a description of these, and then goes on to the blue-light receptors crypto-chrome and phototropin, which use other chemical mechanisms, and concludes with a discus-sion of ultraviolet-B receptors.

On braided block codes

Two families of braided block codes are analyzed, tightly braided block codes and sparsely braided block codes. Bounds on the free distance of tightly braided block codes are derived. Asymptotic iterative decoding performance of sparsely braided block codes is studied

Samspel för förändring : En konsultationsmodell för arbete med elever i svårigheter

Popular Abstract in Swedish Huvudsyftet med avhandlingen är att formulera en teoretiskt och empiriskt förankrad konsultationsmodell för psykologer i skolsammanhang. Idéer och handlingsstrategier tydliggörs så att de kan tillämpas, värderas och vidareutvecklas av andra yrkesutövare. De tänks även kunna utgöra en referensram för psykologers, specialpedagogers och andra specialisters teamarbete. VidaThe primary aim of this thesis is to formulate a theoretically and empirically based consultation model for psychologists in school contexts. Ideas and strategies are clarified so that they can be applied, evaluated, and further developed by other professionals. The model has been constructed with an interactional approach, with the stress on patterns of interaction between grown-ups and children

Study of safety culture at two air traffic control centres

The aim of this short paper is to present an ongoing joint research project, Human Factors in Air Navigation Services (HUFA), between the Swedish Civil Aviation Administration and Lund University. Results from the study will only be given very briefly. The project focuses on human and organizational factors and safety in air traffic control.

Communication, Rationality, and Conceptual Changes in Scientific Theories

This article outlines how conceptual spaces theory applies to modeling changes of scientific frameworks when these are treated as spatial structures rather than as linguistic entities. The theory is briefly introduced and five types of changes are presented. It is then contrasted with Michael Friedman’s neo-Kantian account that seeks to render Kuhn’s “paradigm shift” as a communicatively rational

Future perspectives for the history of the Nordic languages.

Speculations about the future of the Scandinavian standard languages concerning the degree of standardization and in relation to the expanding use of Anglo-American for various purposes. Also the prospects of Swedish in Finland and Neo-Norwegian in Norway are discussed.
