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.

Popular Abstract in Swedish Stroke, som kan orsakas av att en hjärnartär blockeras av en blodpropp, är en av de vanligaste orsakerna till död eller handikapp bland vuxna människor, men få behandlingsalternativ existerar. Två olika potentiella behandlingsstrategier är 1) att skydda nervceller från att dö på grund av stroke och 2) att i efterhand ersätta förlorade celler och nervcellskretsar. Ett säIn this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation o

This book investigates the relationship between the quality of working life (QWL) and competitiveness in the specific context of organisational innovations in Sweden. It proceeds by way of reviewing the literature of both a general theoretical nature on innovations, including Swedish research, and then looks more closely at the empirical evidence on the QWL-competitiveness relationship at the micr
