Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu

Syftet med denna avhandling har varit att undersöka tvångsvårdens legitimitet. För det ändamålet har jag genomfört, spelat in och transkriberat kvalitativa intervjuer med 80 klienter – som var föremål för LVM-vård våren 2006 – samt deras socialsekreterare när klienterna dels var intagna på LVM-hem och dels vid en uppföljning cirka sex månader efter tvångsvårdens slut. Avhandlingen utgår från fem The aim of this dissertation was to examine the legitimacy and the legitimizing of compulsory care for substance abusers according to LVM. For this purpose I have conducted, recorded and transcribed qualitative interviews with 80 clients – taken into such care in spring 2006 – and their social welfare officers when the clients were in compulsory care and then again about six months after its termi

Popular Abstract in Swedish Det har blivit vanligt med beskrivningar av hur olika trender påverkar det sätt på vilket arbetslivet utformas. I första hand rör det sig om informationsteknikens inflytande inom i stort sett alla samhällsområden men det handlar också om en globaliserad ekonomi, ökad konkurrens, samt strävan efter högre kvalitet och större flexibilitet. Denna utveckling kan förstås som The study explores the interaction of general management ideas like TQM (here referred to as technocratic visions) and microprocesses of narrating and organizing in two different contexts: the public sector (health care) and the private sector (manufacturing) in Sweden. The purpose is to provide a better understanding of what happens when models of this type are introduced into a work organization

Popular Abstract in Swedish Avhandlingens syfte är att genom en empirisk undersökning öka förståelsen av tidigt föräldraskap till barn med Downs syndrom. Jag utgår ifrån föräldrarnas livsvärld och utvecklar ett medföljande arbetssätt. Tio familjer med nyfödda barn med Downs syndrom följs genom regelbundna hembesök under det första året med barnet. Tillsammans med en medarbetare samtalar jag med föThe purpose of this dissertation was to increase - through an empirical investigation - our understanding of early parenthood in relation to children with Down syndrome. My point of departure has been the parents’ life-worlds, and I have developed an accompanying working method. Ten families with newborn infants with Down syndrome were followed through regular home visits during the first year of

Milk is a dilute aqueous dispersion with a complex mixture of proteins, fat, carbohydrates, vitamins and minerals. Milk membrane lipids are a part of the milk fat globule membrane (MFGM), which covers the fat globules. During dairy processing membrane material is released and surface structure features are altered. The presence of free membrane material as well as various surfaces might influence

At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged. A Pil

Collagen-induced arthritis (CIA) is one of the most commonly used animal models for Rheumatoid arthritis (RA). CIA is induced in susceptible mouse strains after immunization with heterologous type II collagen (CII). In mice of the H-2q haplotype rat CII (rCII) is used whereas in mice of the H-2r haplotype bovine CII is utilized. The broad objective of this thesis was to gain an understanding of th

Autoignition in SI engines is an abnormal combustion mode and may lead to engine knock which is an undesired phenomenon in SI engines. It may cause damage and it is a source of noise in engines. Knock limits the compression ratio of the engine and a low compression ratio means low fuel conversion efficiency of the engine. This thesis presents a theoretical investigation about the modeling of the e

Popular Abstract in Swedish Jämte korrosionsangrepp är skador på grund av saltfrostangrepp den vanligaste skadetypen hos betongkonstruktioner som utsätts för miljöer med fukt, salt och frost. Exempel på sådana miljöer är marina miljöer och tösaltade vägmiljöer. Betongens saltfrostbeständighet bestäms till stor del av betongsammansättningen, främst av förhållandet mellan mängden vatten och cement oAbstract This thesis presents the results of an investigation of the influence of ageing on the salt-frost resistance of concrete. The ageing mechanisms investigated were hydration, drying and carbonation. Specimens of ‘micro’-concrete, either with OPC alone as the binder or with silica or slag as part of the binder, were freeze/thaw tested at different ages after casting. Prior to testing, the sp

Popular Abstract in Swedish För att kunna simulera de fysikaliska fenomen som pågår i förbränning, krävs även en beskrivning av den kinetik som ingår i förbränningsprocessen. För detta ändamål utvecklas kinetiska modeller. En kinetisk modell är en lista med kemiska reaktioner och reaktionshastighetsparametrar. Modellernas tillämpningsområde begränsas av de valideringsfall och de fysikaliska parameThe simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. A software package, BlueBellMouse, has been developed to facilitate a deeper automatization and ease of simulation, reduction and optimization of kinetic models. A kinetic model is made of a list o

In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial

Popular Abstract in Swedish Denna avhandling inom forskarutbildningsämnet arbetsmiljöteknik beskriver nyutvecklade provtagnings- och analysmetoder för att undersöka hur reaktionsbenägna luftföroreningar uppkommer och sprids i arbetsmiljön. Antalet människor som drabbas av allergier har ökat de senaste årtiondena. Många av de mekanismer som ger upphov till allergier och överkänslighetsreaktioner kMany sources of airborne contaminants have always been present in various work environments. With the development of thermosetting plastic systems, the use of reactive chemical compounds was greatly increased and thus also the risk of exposure to reactive and potentially hazardous compounds. Exposure can occur in many situations, not only at the workplace where the raw materials are handled. The f

The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. In this thesis, the properties of heavy rainfall in a 73 000 km2 area

BACKGROUND: In the prostate, the importance of sex hormones for its normal development and function is well known. However, it has been proposed that various neuroendocrine (NE) hormones and growth factors may be involved in the pathogenesis of prostatic carcinoma (CaP). Neuroendocrine differentiation appears to be associated with tumour progression and the androgen-independent state, for which th

This thesis describes an extended flamelet approach for modelling of soot formation in turbulent hydrocarbons diffusion flames. Detailed chemical kinetic mechanisms are used to compute species concentrations, temperature, density and soot formation rates as functions of flamelet coordinates in the space of mixture fraction and scalar dissipation rate. An ensemble average based on a presumed probab

Popular Abstract in Swedish Tidigare trodde man att den vuxna hjärnan inte hade någon förmåga att nybilda nervceller. Detta skulle innebära att nervceller aldrig blev ersatta om de skadades eller dog. Nu vet man däremot att den vuxna hjärnan fortfarande producerar nya nervceller från särskilda moderceller, s.k. stamceller, belägna i åtminstone två områden i hjärnan: subgranulära zonen i hippocamThe adult brain constantly produces new neurons from endogenous neural progenitor cells located in at least two regions, the subgranular zone (SGZ) in dentate gyrus of the hippocampus, and the subventricular zone (SVZ). Major efforts are underway to discover the functional significance of new neurons in the adult brain. Several studies have indicated a relationship exists between newborn hippoca
