Anders Nygrens ambition was to develop a criterion by which he could distinguish between science and non-science. This is th K(v) of Nygren. According to Nygreb tgere are three ways of arguing in science which all fullfill the demand of K(v): a) deductive argumentation b) empirical argumentation and c) philosophical argumentation. a) and b) operate at the material level and c) at the formal one. c
Popular Abstract in Swedish Forskningsfokus i den här avhandlingen har varit framgång i säljande skapad i säljare och köparinteraktioner på och mellan makro-, meso- och mikronivå. Framgång har studerats som ett värde med konsekvenser för utbytesprocessen eftersom framgång påverkar aktörernas agerande i säljar- och köparinteraktionen på olika nivåer i företagen. Studien är avgränsad till framgång i
Popular Abstract in Swedish Denna avhandling beskriver arbetet med att finna en effektiv metod för att rena glykoproteiner. Glykoproteiner är en grupp biomolekyler som består av ett skelett av protein där ett antal socker-molekyler är fästa. Glykoproteiner finns i alla virus, mikroorganismer, växter och djur. Där består deras uppgifter bland annat i att bilda strukturelement som cellväggar, de fun
Popular Abstract in Swedish Ekonomiska och miljömässiga problem gör det svårt att bygga ut kraftledningsnätet i samma takt som efterfrågan på elenergi ökar. Ett alternativ är att öka belastningen av befintliga kraftledningar på bekostnad av de säkerhetsmarginaler som finns. En av flera dimensionerande faktorer är risken för otillräckligt dämpade effektpendlingar mellan generatorer i kraftsystemet.Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. A consequence is that power system damping is reduced, leading to a risk of poorly damped power oscillations between the generators. This thesis proposes the
During the 1990’s the diversity idea entered the Swedish socio-political debate under the name ‘mångfald’. The concept originated in the United States and discusses how organizations can be more efficient if they combat discrimination and acknowledge differences. This development attracted the attention of mass-media and led to the publication of books, articles and reports that advocated or comme
New anti-inflammatory drugs with fewer adverse effects than existing drugs may prove to be useful in the treatment of several inflammatory disorders. A critical step in acute inflammation is the infiltration of neutrophils into tissues. Therefore, molecules that target and inhibit this early inflammatory event are attractive to engineer to suit medical needs. The Chemotaxis Inhibitory Protein of
OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is a major health problem with high societal costs. The Global Initiative for Chronic Lung Disease (GOLD) has identified a need for health economics data for COPD. For chronic diseases, such as COPD, where the natural history of disease is lifetime, a modeling approach for economic evaluation may be more realistic than prospective, piggy-back
The European X-ray Free Electron Laser (XFEL) will deliver 30,000 fully coherent, high brilliance X-ray pulses per second each with a duration below 100 fs. This will allow the recording of diffraction patterns of single complex molecules and the study of ultra-fast processes. Silicon pixel sensors will be used to record the diffraction images. In 3 years of operation the sensors will be exposed t
The social differentiation of mobile work is complex. While some people are in a position of control over, and initiate, mobilities, others are captivated by it (Massey 1994). The focus of this WP is transport workers, those who provide mobility: truck drivers, cycle couriers and uber drivers. It is inspired by previous studies of less privileged workers in the power geometry of mobile work: of se
Denna avhandling har tre utgångspunkter. Den första är den europeiska sociala dialogen (ESD), vilken har kritiserats för att sakna kapacitet för att förbättra arbetsvillkor i EU. Den andra är det globala systemet för kollektivavtal och förhandlingar som har utvecklats genom ITFs kampanj mot bekvämlighetsflagg (ITF FOC), vilket anses ha kapacitet att förbättra villkor för sjömän på global nivå. DenThere are three starting points for this thesis. First, there is the system of ESD, which is criticised for lacking capacity to improve the working conditions within the EU. Secondly, there is the system developed through the global ITF FOC campaign, which is considered to have capacity to improve working conditions for seafarers at a global level. Thirdly, there is the theory on self-referential
Contemporary debates on sustainability usually relies on standardised and normative categories, such as ‘social’ and ‘nature’, and on linear notions of time. This study explores a more complex perspective on the delicate borderlands between the ‘un-sustainable’ and the ‘sustainable’. A particular material and a particular place stand at the centre of attention: woollen Merino fibre on the South Am
Nanostructures are found everywhere in our environment, of either natural oranthropogenic origin. Volcanoes emit them, breakdown of plastic releases them, andthey are even produced in candlelight. Designed nanostructures are used in sunscreen,food products, electronics and many more readily available products. Still, there are alot of things we do not know about their behavior. To call them miniscThis thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. Similarly, the nanomaterial sources vary from spherical titanium dioxide, gold, and polystyrene nanoparticles to novel nanowires of gallium arsenide
Atmospheric carbon dioxide enrichment (eCO2) can enhance plant carbon uptake and growth1–5, thereby providing an important negative feedback to climate change by slowing the rate of increase of the atmospheric CO2 concentration6. Although evidence gathered from young aggrading forests has generally indicated a strong CO2 fertilization effect on biomass growth3–5, it is unclear whether mature fores
We describe the clinical presentation and outcome in a series of eight patients with systemic necrotizing vasculitis and severe alpha1-antitrypsin (AAT) deficiency followed up at three Swedish hospitals during 1968-92. We also review six other cases reported in the literature during the same period. Diagnosis of severe AAT deficiency was based on the presence of the PiZZ phenotype, or low plasma t
The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years
Bacterial genomes typically consist of a single chromosome and, optionally, one or more plasmids. But whole-genome sequencing reveals about ten per-cent of them to be multipartite, with additional replicons which by size and indispensability are considered secondary chromosomes. This raises the questions of how their replication and partition is managed without compromising genome stability and of
