The chapter argues that language, which rests on the sharing of linguistic norms, honest information, and moral norms, evolved through a co-evolutionary process with a pivotal role for intersubjectivity. Mainstream evolutionary models, based only on individual-level and gene-level selection, are argued to be incapable to account for such sharing of care, values and information, thus implying the n
Abstract There is a crisis discussed in the discipline of Information Systems. Those who perceive such a crisis to exist are by no means agreed, as to its nature and origins. Our inquiry shows that there are a three distinct “crises” being debated. The first of these relates to the Substance and boundaries of the discipline itself and if it is even a discipline at all. Another “crisis” relates to
The binaries PSR J1141-6545 and PSR B2303+46 each appear to contain a white dwarf that formed before the neutron star. We describe an evolutionary pathway to produce these two systems. In this scenario, the primary transfers its envelope on to the secondary, which is then the more massive of the two stars, and indeed sufficiently massive later to produce a neutron star via a supernova. The core of
Photosynthesis in plants is a very complicated process, utilizing two photosystems in series to carry out the very energy-demanding process of oxidizing water to molecular oxygen and reducing carbon dioxide to organic compounds. The first photosynthetic organisms, living more than 3.4, perhaps even 3.8 Ga, i.e. American billion (109) years ago, carried out a simpler process, without oxygen product
Popular Abstract in Swedish Gastroesofageal refluxsjukdom är ett tillstånd som kännetecknas av att magsyra åker upp i matstrupen (reflux). Reflux är ett normalt fenomen som förekommer hos alla individer utan att orsaka symtom eller vävnadsskador. Hur detta normaltillstånd utvecklas till ett sjukdomstillstånd är ej helt klarlagt. Reflux förhindras normalt av en barriär vid övergången mellan matstruThere is a persisting controversy concerning the definition, etiology and pathogenesis of Barrett's esophagus. The dramatic and parallel increase in the incidence of esophageal and junctional adenocarcinoma over the past decades justifies an evaluation of the pathophysiology of premalignant metaplastic changes of the esophagus and the gastroesophageal junction. Patients were evaluated with upper G
The thesis Housing Culture, Information Flows, and Craftsmen 1740-1820 (Bostadskultur, informationsflöden och hantverkare 1740-1820) investigates two mansion houses – Bålby in Närke and Skottsbergska gården in Karlshamn – with the focus on craftsmen and their clients. This is in order to analyse the relationship between professional craftsmen in the capital and in other regions. The clients have a
The early host response to an infection is dependent on an efficient innate immune system. The human contact system once activated at a bacterial surface results in the induction of proinflammatory reactions and the release of antimicrobial peptides, However, under severe conditions its systemic activation A may evoke the generation of pathologic levels of kinins and a consumption of contact facto
Popular Abstract in Swedish Allergiska besvär från luftvägarna utgör ett stort och växande folkhälsoproblem. Det finns idag ingen bot mot dessa sjukdomar och de kan, om de inte behandlas, utgöra ett betydande hinder i vardagen. Även om dagens mediciner i de allra flesta fall kuperar symtomen väl, vet man, att många patienter är odiagnostiserade eller saknar behandling trots diagnos. Målet med behAllergic diseases, which constitute a global health problem, have been defined as one of the epidemics of the twenty-first century. Since there are no cures for allergic diseases today, the goal of treatment is to get the disease under control so that the patient can live a normal life with optimal chances of development. Patient-reported outcomes for control assessment have been a focus of attent
This chapter highlights user perspectives related to the development of ICT and the launching of political strategies to involve users in the IT society. Strategies are discussed in relation to cooperation between technical and social scientists. The author points to the fact that the diffrences between various theoretical understandings of the interaction between technology and social change tend
Background: Becoming critical ill or severely injured leads to a process of worry, anxiety and pain. Patients in intensive care sometimes have strange and frightening experiences and may show symptoms of acute confusion or delirium. CAM-ICU, the confusion assessment method for the intensive care unit, was based on the DSM IV, the Diagnostic and Statistic Manual of Mental Disorders IV, and today, h
The optical design for the proposed Euro50 extremely large telescopewith integrated adaptive optics (AO) is presented. For atmosphericturbulence correction, we propose using single and dual-conjugate AOsystems working with natural and laser guide stars. The corrective shapeof the deformable mirrors (DMs) is derived from an analytical algorithmbased on minimization of the sum of the residual power
För femton år sedan beskrevs Internet och framväxande digitala tjänster ofta med hjälp av ord som Cyberspace och virtuella verkligheter. Under senare år har andra efemära metaforer använts. Idag talas det mer om ”molnet” och molntjänster. Sällan har konkreta fysiska anläggningar och tung infrastruktur använts i marknadsföring och i frammanandet av visioner från företag och organisationer som arbet
Researchers often aim to make correct inferences both about that which is actually studied (internal validity) and about what the results generalize to (external validity). The language of internal and external validity is not used by everyone, but many of us would agree that intuitively the distinction makes a lot of sense. Two claims are commonly made with respect to internal and external validi
Randomized controlled trials (RCTs) in palliative cancer care often experience methodological problems. In this paper we discuss issues of major concern, including recruitment, patient attrition and compliance, arising from an RCT that compared comprehensive palliative care to conventional care. The main criteria for trial entry were incurable malignant disease and a survival expectancy of between
ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. The aim of this thesis was to identify and characterize new genetic regions linked to reproductive performance and autoimmune inflammation in female mice. Collagen-induced arthritis (CIA
An accurate and reasonable technique combining direct absorption spectroscopy and laser-induced fluorescence (LIF) methods is developed to quantitatively measure the concentrations of hydroxyl in CH4/air flat laminar flame. In our approach, particular attention is paid to the linear laser-induced fluorescence and absorption processes, and experimental details as well. Through measuring the tempera
The dedicated production of biomass crops and the collection of residues in agriculture and forestry can lead to undesirable negative impacts and it is crucial that practices are found that ensure that these impacts are avoided or mitigated as far as possible. This chapter concerns the use of biomass for energy and the connection between increased bioenergy use and land use change (LUC). Land use
