The relationship between the North Atlantic oscillation (NAO) and winter temperature and precipitation over northern Europe has long been known. However, its strength is variable within this region. In this paper, an analysis of the regional variability of the influence of the NAO on winter precipitation in northern Europe is developed using empirical orthogonal function analysis, cluster analysis

In this article the nation is shown to be a historical subject. As such, it is constructed and constantly reconstructed by discursive practices of power and knowledge. The author argues that the symbiotic interlinkage between nationalism and the organising knowledge principle of historicity, is an example of a power practice in the modern state. Throughout the article, it is shown that this practi

We investigated patterns of isozyme variation and the hierarchic structure of genetic diversity in 25 Scandinavian populations of the lilioid herb, Anthericum liliago. Isozyme data suggest that tetraploid A. liliago has an allopolyploid origin and that A. ramosum may be one of its diploid progenitors. Two populations contained known or suspected hybrids between A. liliago and A. ramosum. Isozymes

Background New treatment strategies for early rheumatoid arthritis are evolving rapidly. We aimed to compare addition of conventional disease-modifying antirheumatic drugs (sulfasalazine and hydroxychloroquine) with addition of a tumour necrosis factor antagonist (infliximab) to methotrexate in patients with early rheumatoid arthritis. Methods We undertook a randomised trial in 15 rheumatology uni

OBJECTIVE-Previous studies have suggested that preterm birth is associated with diabetes later in life. These studies have shown inconsistent results for late preterm births and have had various limitations, including the inability to evaluate diabetic outpatients or to estimate risk across the full range of gestational ages. Our objective was to determine whether preterm birth is associated with

Recent empirical evidence strongly supports Jacobs's (1969) externality hypothesis that urban diversity provides a more favorable environment for economic development than urban specialization. In order to correctly gauge Jacobs's hypothesis, economic development should be understood as a result of innovations. Furthermore, a relevant diversity measure should take into account the degree of divers

OBJECTIVE: To assess the prevalence of primary hip osteoarthritis (OA) in Iceland. To compare the prevalence of primary hip OA in Iceland with published rates of primary hip OA for related Scandinavian populations.METHODS: Roentgenographs were examined of 1530 Icelandic people 35 years or older (653 males, 877 females) subjected to colon radiography during the years 1990-1996. The radiographs exam
