This thesis analyses self-employment, sickness absence and early retirement pension among immigrants in Sweden. The empirical analysis investigate a period, 1981-2003, characterized by a transformation from high employment and expansion of the welfare state in the 1980s into a state with high unemployment and tightening social insurance systems during in the 1990s, This thesis goes beyond most pre

Succinate:quinone reductases are membrane-bound enzymes that catalyze electron transfer from succinate to quinone. Some enzymes in vivo reduce ubiquinone (exergonic reaction) whereas others reduce menaquinone (endergonic reaction). The succinate:menaquinone reductases all contain two heme groups in the membrane anchor of the enzyme: a proximal heme (heme b(P)) located close to the negative side of

I egenskap av lärarstudent med ett år kvar av utbildningen har jag fortfarande vissa svårigheter med att tolka den nya läroplanen, Lgr 11. Jag har därför undersökt hur yrkesaktiva lärare tolkar och hanterar den nya läroplanen. Studien innehåller också en analys av likvärdigheten av lärarnas tolkningar eftersom nya rapporter påpekar bristande likvärdighet i den svenska skolan. Studien är kvalitativAs a teacher student with only one year left until fully educated, I still have some difficulties completely understanding and interpreting the new curriculum, Lgr 11, for the higher grades of Swedish elementary school. Therefore I examined how working teachers tend to interpret and deal with this new curriculum. The thesis also contains an analysis of the teachers’ answers in the perspective of e

Populärvetenskaplig sammanfattning: Återfyllning av energibrunnar har tidigare inte varit aktuellt i någon större grad. De senaste åren har det höjts röster från ett fåtal kommuner om att installationen av dessa system kan skapa en potentiell föroreningsspridning. Trots att installationerna i verkligheten skapat få fall där problem uppstått, fortsätter vissa kommuner att sätta restriktioner mot öp

The aim of this essay is to establish what purpose Roman cattle had. Why did Roman farmers breed cattle? Were the animal’s main purpose to be used as draught animals, or were there other roles that were more important. I also want to establish how the different roles relate to each other, were the same animals used for different purposes. To do this I have chosen to study four Roman agricultural w

Current cancer treatments can be non-specific, aggressive, and often lead to poor quality of life due to significant side effects. There is a dire need for personalised medicine and accurate tumour subtyping, particularly with cancers with high levels of heterogeneity. Spatial omics is transforming the way in which we understand and treat cancer, paving the way for more patient-specific treatments

Växelvis boende med en ungefärlig jämn uppdelning är vanligast förekommande i Skandinavien och har således mestadels studerats i denna kontext. Få studier har dock inriktat sig på yngre barn eller kvalitativt undersökt det växelvisa föräldra- och medföräldraskapet. Som en komponent i förståelsen av barnets tidiga anknytnings- och socioemotionella utvecklingsmiljö, fokuserar vi här på hur föräldrar

Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. A reduction in the storage size of each collision ev

Numerous past studies investigating the performance of hedge funds suffer from two distinct problems: unreliable and biased return data inherent in virtually all databases and the use of static asset-pricing models. Using “indexes of indexes” for our hedge fund returns, both free of biases and highly representative, we investigate which risk factors investors are exposed to and whether hedge fund

Protein transport across the cytoplasmic membrane of bacterial cells is mediated by either the general secretion (Sec) system or the twin-arginine translocase (Tat). The Tat machinery exports folded and cofactor-containing proteins from the cytoplasm to the periplasm by using the transmembrane proton motive force as a source of energy. The Tat apparatus apparently senses the folded state of its pr
