In this paper, we investigate the social herding phenomenon known as informational cascades, in which sequential inter-agent communication might lead to epistemic failures at group level, despite availability of information that should be sufficient to track the truth. We model an example of a cascade, and check the correctness of the individual reasoning of each agent involved, using two alternat

Popular Abstract in Swedish Med dagens medicinska teknik måste mottagare av transplanterade organ ta immundämpande läkemedel varje dag för att undvika att transplantatet avstöts. Dessa patienter får ett generellt nedsatt immunförsvar vilket betyder att de blir mottagliga för infektionssjukdomar, samt har en ökad risk för att utveckla tumörer. När det gäller transplantation av vävnader från andra aInhibition of the costimulatory molecules B7 and CD40L with CTLA4Ig and anti-CD40L administered only during the first week after transplantation induces indefinite survival of allo- and xenogeneic heart transplants and significantly prolongs skin grafts in C3H mice. However, this treatment protocol is not as effective in C57BL/6 mice which reject skin transplants with nearly the same median surviv

Popular Abstract in Swedish För människor med centrala skotom är den excentriska synen den enda som finns att tillgå. Också för den som lär sig att använda sin excentriska syn är denna sämre än den centrala synen, och det av två helt olika skäl: att ögonoptiken kan ge stora avbildningsfel excentriskt respektive att näthinnan utanför makula har en lägre funktion. Denna avhandling handlar om den föFor people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina. This thesis deals with the first of the

I den här rapporten behandlas en i kommunsammanhang ständigt aktuell fråga, nämligen samarbete mellan ledande politiker och tjänstemän. Sådant samarbete måste organiseras lokalt i varje enskild kommun, eftersom staten inte reglerar det i kommunallagen eller på annat sätt. Ledande politiker och tjänstemän har skilda förutsättningar. Politikerna är förtroendevalda på så sätt att de får sina uppdrag

Estimation of high-resolution multidimensional spectra from unevenly sampled limited sized data sets plays an important role in a large variety of signal processing applications. In this work, we develop a high-resolution non-parametric estimator for unevenly sampled N-dimensional data based on a recently introduced iterative method, the so-called iterative adaptive approach (IAA). The proposed es

Motor neuron degeneration is a critical phenomenon during spinal cord injuries and some neurodegenerative diseases. However, the mechanisms by which cell death is induced in these neurons are poorly understood. One reason for this, is the lack of model systems in which the survival and death of adult motor neurons can be studied under controlled conditions. This thesis is an attempt to develop suc

Popular Abstract in Swedish Att finna metoder som är snabbare, ger noggrannare resultat och utökar möjligheterna är det övergripande målet för forskningen inom teoretisk kemi. Denna avhandling utgör inget undantag. Sålunda, CI rutiner som möjliggör större beräkningar än tidigare har implementerats i RASSCF modulen i Molcas; nya metoder att lokalisera multipolmomement och polariserbarheter har utveThe method development research in the field of theoretical chemistry is the never ending quest for methods that are faster, gives more accurate results, and expands the possibilities. The work in this thesis is no exception to that statement. Thus a CI routine more suited for calculations on large active spaces was implemented in the RASSCF code of Molcas; a new scheme for localizing multipole mo

Simulation and computer-aided analysis of complex mechanical systems has become a task of increasing importance in computational mechanics. It requires software tools combining modeling support, efficient generation of the equations of motion as well as modern numerical solution and system analysis techniques.

Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation

The placement of verse 20 in Psalm 72 has long puzzled scholars and has raised a number of questions: Why is תפלה used? Why does it state that the prayers of David are ended? Where does this leave Solomon (v. 1)? Why is it placed after the doxology of vv. 18–19? And why is it found in the middle of the Elohistic Psalter? To solve these problems, a number of suggestions have been presented, none of

Popular Abstract in Swedish Avhandlingen handlar om de personliga följderna av de tidiga konsekvenserna av kronisk ledgångsreumatism, hur det påverkar personernas arbetsliv och hur de hanterar detta. I denna kvalitativa studie har tematiserade intervjuer använts. Tjugotre personer, vilka nyligen diagnostiserats med kronisk ledgångsreumatism, var intervjuade två gånger med två års mellanrum. StudieThis dissertation discusses the personal implications of the early consequences of rheumatoid arthritis, how they effect the person's working life and how they are dealt with. In this qualitative study thematized interviews are used. Twenty-three persons, recently diagnosed with rheumatoid arthritis, were interviewed twice, two years apart. The study is influenced by an interactionist perspective
