Aim of the study, background, theory and method The two aims of this study are to describe and analyse: i) how drug abusers have transformed their lives from the time when they did not use drugs, to becoming drug abusers, and finally leaving drugs behind them; and ii) what it means to be socially integrated with one's experience of having been a drug abuser. The women and men who participated in
The aim of this thesis is to examine how learner-general developmental stages in syntax and morphology interact with a language-specific factor, the influence of—or transfer from— the language learner’s first (L1) or previously learned second (L2) language on the acquisition of a third language (L3). It thereby aims to bring together two lines of research whose main concepts—transfer and developme
Individual characteristic features in voice and speech are important in ear witness identification. A target-absent lineup with six foils was used to analyze the influence of voice and speech features on recognition. The participants’ response for two voice foils were particularly successful in the sense that they were most often rejected. These voice foils were characterized by the features’ arti
Imminent crises and the much-needed transition to a sustainable society bring knowledge about de-implementation to the fore. Using case studies with inspiration from process tracing, and with tools from Charles Tilly’s theory on Durable inequality, we identify mechanisms that generate inequality and counteract the implementation of recovery – and strength-based practices.

Compensational voting refers to when voters cast a vote for a more extreme party than they prefer, in order to push policies closer to an ideal point. This article develops the idea of compensational voting in regard to pre-electoral coalition signals and polling trends. The argument is that a significant share of voters consider the relative strength of the parties in their preferred pre-electoraCompensational voting refers to when voters cast a vote for a more extreme party than they prefer, in order to push policies closer to an ideal point.

The first chapter investigates the relationship between economic media sentiment and individuals’ expectations and perceptions about economic conditions. We test if economic media sentiment Granger-causes individuals’ expectations and opinions concerning economic conditions, controlling for macroeconomic variables. We develop a measure of economic media sentiment using a supervised machine learninThe first chapter investigates the relationship between economic media sentiment and individuals’ expectations and perceptions about economic conditions.

We describe a number of research projects at Lund Univer- sity Cognitive Science. The first project focuses on visual attention. The second area is haptic perceptions by robots. The third area is anticipation in groups of robots. The final research area concerns building computa- tional tools that can be used to design large-scale cognitive models which will ultimately allow results from the diffe
Infectious symptoms in infants and their families are common. With rising age the number of symptom day decreases, but increases again for the parents of infants. About one quarter of the symptom days lead to absence from daycare among the infants but the social remuneration system was used by the parents only in 1/3 of the absence days. Among the adults 12% of the symptoms days lead to absence fr
Vi följer en foton på dess färd genom världsrymden, från att den skapas i en avlägsen stjärna till att den landar på någons näthinna. Denna resa kan ta tusentals år. En del fotoner absorberas längs vägen, men just vår foton når hela vägen fram och gör att vi kan se vårt universum. Men även om fotonens resa slutar i ditt öga, så färdas informationen vidare till din hjärna.I denna visning utforskar Follow the journey of a single photon as it is produced in a distant star, before travelling across the vast expanse of space to land on someone's retina.This fulldome planetarium show explores some of the fascinating processes of the cosmos, from astrophysics to the biology of the eye and brain.
Gear hobbing is well established and one of the most cost effective manufacturing methods of involute gears. In the hobbing of lead crown corrected helical gears, a well know drawback is the non-uniform systematic tooth alignment deviation that arises. This is sometimes denoted as flank twist. The inevitable tooth alignment deviation, together with other source deviations, must not exceed the spec
