This paper considers a housing market with price restrictions. On such markets, the existence of a unique minimum rationing equilibrium price vector has been established for each preference profile on a general preference domain that contains almost all preference profiles. This vector can be used as a key ingredient in a direct and strategy-proof allocation mechanism. The main contribution of thi

Popular Abstract in Swedish Sjögrens syndrom är en autoimmun sjukdom, vilket betyder att immunsystemet felreagerar och angriper kroppens egen vävnad. Nittio procent av dem som får diagnosen är kvinnor, av vilka de flesta är mellan 40 och 60 år. Vid Sjögrens syndrom, som tillhör en av våra vanligaste reumatiska sjukdomar, är det framförallt tår- och spottkörtlar som angrips och blir inflammerade. DPrimary Sjögren’s syndrome (SS) is a chronic autoimmune disease of unknown etiology. The disease primarily involves lachrymal and salivary glands, leading to dryness of the eyes and mouth, but a wide spectrum of exocrine and non-exocrine disease manifestations may be seen. A characteristic property of primary SS is the production of autoantibodies directed against intracellular, often DNA/RNA-modi

Based on Brandtler (2012), this paper argues that polarity items are sensitive to evaluability, a concept that refers to the possibility of accepting or rejecting an utterance as true in a communicative exchange. The main distinction is made between evaluable and non-evaluable utterances. The evaluable category comprises any clause that asserts, presupposes or entails the truth of an affirmative o

Popular Abstract in Swedish Utgångspunkten för denna avhandling har varit att studera användningen av datorer i arbetet utifrån ett mer holistiskt perspektiv än vad som varit brukligt i tidigare traditionell hälsoforskning om datoranvändning, genom att även inkludera arbetsinnehållet som inte utförs med hjälp av datorn. Avhandlingens ansatts skiljer sig således från tidigare traditionell hälsoforsThis thesis aims at investigating computer use at work from a more holistic work content perspective by also studying non-computer work content, in contrast to the previous approach in occupational health research that focused almost solely on computer work content. It was argued here that non-computer work content has also become significant to the overall work situation for computer users. This

Popular Abstract in Swedish Kvinnomisshandel är ett ärende som skiljer sig från andra polisärenden genom att det beskrivs som svårt att hantera. Polismän säger sig vilja agera men på grund av olika svårigheter - organisation, lagstiftning, de inblandades inställning - är man förhindrad att ingripa. I Vilja med förhinder låter Magnus Lundberg polismännen komma till tals. Genom åskådliggörande exempPolice officers often talk about wife abuse as a practical problem in their work situation. This problem is often used to explain why the officers do not file a complaint when they have reason to believe that a woman has been abused, something they are obliged to do according to Swedish law. One may approach these explanations as reflections of “reality”, as expressions of complicated work conditi

A century after the great war broke out, studies on politics of memory and commemoration have grown into a vast and vital academic field. This book approaches the theme "monument and memory" from architectural, literary, philosophical and theological perspectives. Drawing on diverse sources – from Augustine to Freud, from early photographs to contemporary urban monuments – the contributing authors

En solfångarhybrid har utvecklats och utvärderats på avdelningen för Energi och ByggnadsDesign på Lunds Tekniska Högskola, LTH. Solfångarhybriden, ”Solfönstret”, består av solcellslaminerade absorbatorer placerade i ett fönster bakom glasrutorna. Solfönstret finns byggt i ett enfamiljshus, Solgården, i Älvkarleö utanför Gävle. För att minska investeringskostnaderna för solel har reflektorer placerA PV/T collector has been developed and evaluated at the department of Energy and Building Design at the Technical University of Lund, LTH in Sweden. The PV/T, a “solar window” made of PV cells laminated on solar absorbers is placed in a window behind the glazing. The solar window is built into a single family house, Solgården, in Älvkarleö outside Gävle in the eastern part of Sweden. To reduce th

This is a study on the potential of NOAA satellite data for operational early warning and food security monitoring at a national level. Ethiopian NOAA NDVI 15-day composites (1981-1985) are analysed and compared to precipitation data including time series records from more than 200 stations. Anomaly analyses are introduced and the regional distribution of the 1984 drought is clearly identified. A

Popular Abstract in Swedish Immunförsvaret, som även kan benämnas immunsystemet, kan betraktas som ett organ som är utspritt i hela kroppen istället för samlat på ett ställe. Immunsystemet består av ett stort antal vita blodkroppar som finns i blodet, ute i vävnaderna, samt samlade i lymfkörtlar och mjälten. Immunsystemets uppgift är att försvara oss från yttre faror som virus och bakterier samt aThe small intestine contains a large number of T lymphocytes within the single-layered epithelium that separates the gut lumen from the lamina propria. These intraepithelial T lymphocytes have potent cytolytic and immunoregulatory capacities, thought to be important for fighting infections, neoplastic growth, and sustaining epithelial integrity. This thesis is based on three original articles wit

This paper describes how PID controllers can be designed by optimizing performance subject to robustness constraints. The optimization problem is solved using convex-concave programming. The method admits general process descriptions in terms of frequency response data and it can cope with many different constraints. Examples are presented and some pitfalls in optimization are discussed.
