This paper examines the value to Swedish citizens of reducing the risk for salmonella bacteria in chicken filet. The contingent valuation (CV) study is based on the results of a postal questionnaire that was distributed to 2 000 randomly selected Swedish citizens aged 18-74. The valuation format used is a stated preference double bounded dichotomous choice. We employ the non-parametric Turnbull Lo
Popular Abstract in Swedish Markfosfor och mångfald av växter i svenska gräsmarker – en populärvetenskaplig sammanfattning Olika typer av gräsmarkshabitat innehåller en stor och viktig del av mångfalden av växtarter i Skandinavien och i norra Europa. En stor del av arterna är knutna till kulturlandskapet och des's äldre hävdformer. Förändringar i användning och skötsel av gräsmarkerna under detThe semi-natural grassland habitats contain an important part of the plant diversity in Europe. Changes in farming practices have lead to drastic decreases in plant species richness. The aim of the present thesis is to contribute to the knowledge about mechanisms governing the plant species richness in grasslands with emphasis on soil nutrients. Most species rich grasslands are found on soils with
The damage caused by the worldwide increase in natural disasters is staggering, with the poor and marginalised slum communities being the most vulnerable. This paper analyses the key variables and their causal relations underlying the complex system of risk and disaster occurrence in slum areas in El Salvador. Slum dwellers’ views and knowledge are the focus of this inquiry. A better understanding
This paper presents a 28 GHz QVCO intended to be used in an 81-86 GHz E-band transceiver. E-band transceivers using e.g. 16 QAM modulation schemes are sensitive to I/Q phase error. Already a three degree error significantly degrades the bit error rate, and careful control of the phase error of the 28 GHz QVCO is therefore required. In the presented design the phase error can be tuned using four va
Aim: The aim of this study was to explore and understand the complexity of ageing in relation to factors of importance for extending working life. Method: Discourse analysis of documents was used in an integrative review including 128 articles. Result: Four different conceptualisation of ageing are shown to affect older workers’ ability to extend their working life: (a) biological ageing people’s
A description of general models for adsorption kinetics is given. Combinations of the models are compared with adsorption data for the self-associating proteins β-lactoglobulin A and B, from Elofssonet al.(U. M. Elofsson, M. A. Paulsson, and T. Arnebrant,Langmuir,submitted). The adsorption onto methylated silica surfaces was measured by these authors by ellipsometry in phosphate buffer (0.01M,pH 7
It is now well established that the source ofoxygen in photosynthesis is water. The earliest suggestionpreviously known to us had come from Rene´ BernardWurmser (1930). Here, we highlight an earlier report byMonsieur De Fourcroy (1787), who had already discussedthe broad outlines of such a hypothesis in a book onChemistry written for women. We present here a freetranslation of a passage from this
BACKGROUND: This phase 3 study further characterizes the efficacy and safety of reslizumab (a humanized anti-interleukin-5 monoclonal antibody) in patients aged 12-75 years with asthma inadequately controlled by at least a medium-dose inhaled corticosteroid, and blood eosinophils ≥400cells/μL.METHODS: Patients were randomized to receive reslizumab 0.3 or 3.0mg/kg or placebo once/every 4 weeks/16 w
Heritable variation is a prerequisite for evolutionary change, but the relevance of genetic constraints on macroevolutionary timescales is debated. By using two datasets on fossil and contemporary taxa, we show that evolutionary divergence among populations, and to a lesser extent among species, increases with microevolutionary evolvability. We evaluate and reject several hypotheses to explain thi
1. Co-flowering plant species often interact through shared pollinators, with effects ranging from positive (facilitation) to negative (competition). It remains unclear how this variation relates to variation in floral density, floral trait distinctiveness, and local environmental conditions. We studied the effect of grazer exclusion, a proposed local management strategy, on pollinator-mediated pl
Changes in land cover, particularly agricultural intensification, are a primary cause of pollinator decline. Decline and isolation can reduce genetic diversity, reducing adaptive potential and unmasking genetic load. Maintenance of functional connectivity in changing landscapes is necessary to ensure persistence, but how land cover impacts genetic diversity and functional connectivity in butterfli
BACKGROUND: Each year, more than 1.5 million people in Europe have a stroke, and many experience disabilities leading to activity and participation restrictions. Home-based rehabilitation is the recommended approach for stroke rehabilitation, in line with the international shift to integrated care. Despite this, rehabilitation often focuses on the person's physical functions, not the whole life si
