    Melting the Glacial Curtain: The Soft Politics of Scandinavian-Soviet Networks in the Geophysical Field Sciences between Two Polar Years, 1932/33-1957/58

    While providing a brief background of the development of Scandinavian–Russian relations in the polar sciences in the early 20th century, this paper focuses on the period from the 1930s when the Swedish geographer Hans Ahlmann and Norwegian oceanographer Harald Ulrik Sverdrup developed a curiosity of the Soviet Union as a field for the practice of Arctic science. Visit of the Arctic Research Institute in Leningrad in 1934 further enhanced Ahlmann's sympathy and in 1935 he co-founded the Society for the Promotion of Cultural and Scientific Relations between Sweden and the Soviet Union. After further wartime collaboration, Ahlmann returned to the Soviet Union in 1958 and 1960 as president of the International Union of Geographical Sciences. Using his longtime Soviet contacts to penetrate the Iron Curtain, Ahlmann became a key figure in maintaining the flow of scientific information between East and West. New materials from archives open perspectives for better understanding of the international connections and transfer of knowledge in geophysical and geographical science in its formative period. The key message from this paper is that while tensions did exist and presented scientists with differential loyalties, they still managed to find ways to undertake fruitful scientific collaborations even under political restraints and could sometimes play political roles

    Stratigraphy for the Renaissance: Questions of expertise for ‘the environment’ and ‘the Anthropocene’

    This article examines the short history of scientific decision-making and expertise in deliberations about the validity of the term ‘Anthropocene’ by the International Commission on Stratigraphy. Contrary to fears that the Anthropocene debates constitute a politicisation of proper scientific practice, it argues that periodisation and categorisation in science (in stratigraphy, in this case) typically draws on expertise and information outside core disciplinary practice. When broad integrative concepts come into play, knowledge itself is reshaped. Disciplines and ‘non-scientific’ concerns develop new relations with each other. This is what happened in the Renaissance, when science itself emerged in its modern form. Here parallels are drawn between the emergence of the concept ‘the environment’ in the post-war era and the 21st-century struggles over the idea of ‘the Anthropocene’. The politics of science create uncertainties but equally nurture emergent possibilities for analysis that are not unlike the broad categories and periodisations – such as the Renaissance – in the humanities.</jats:p

    Science, Sport et Paysage : le développement des techniques d'entraßnement en altitude depuis 1945

    Today, most elite endurance athletes use high-altitude training to some extent. For at least the last 40 years, it has been linked to increased performance. But how was high-altitude training established as a means of improving performance? And how did the scientific approach to altitude differ from the traditional, natural valuation of mountains as a site for training? High-altitude training was introduced in sports in the post-war period. During the 1960s, it became a highly contested method, with controversies between scientists, athletes, doctors, sport organizations and coaches. What ideas about altitude and performance were important in this process? What type of scientific hypotheses led scientists and sport practitioners towards increasing high-altitude training? Interestingly, those within sports who rejected the scientific, ‘machine-like’ training methods also often valued the mountains. Famous Swedish coach Gösta Olander is one example. He was the most influential protagonist of the natural training method in Sweden, and his base was in VĂ„lĂ„dalen (in JĂ€mtland, near Östersund and Åre). Both Swedish (e.g. Sixten Jernberg, Gunder HĂ€gg) and international athletes (e.g. Michel Jazy and Michel Bernard) came to VĂ„lĂ„dalen. The fresh mountain air and scenic surroundings were important as a place for training camps, but scientists later demystified the mountains via scientific explanations about increased oxygen uptake and increasing hemoglobin levels in the blood. VĂ„lĂ„dalen became a center not only for natural training, but also for scientific monitoring, testing and evaluation. And the setting of international standards regarding high-altitude training had a political aspect, as the issue was addressed when white runners from low altitude were threatened by the results of mainly runners from high altitude countries like Kenya and Ethiopia. Focusing on the Swedish case, we analyze the scientific interest in high-altitude training for sports. Especially, we study the links between science, military and sports.QC 20160127Rational trainin

    Walking Time Is associated With Hippocampal Volume in Overweight and Obese Office Workers

    Objectives: To investigate the long-term effects on cognition and brain function after installing treadmill workstations in offices for 13 months. Methods: Eighty healthy overweight or obese office workers aged 40–67 years were individually randomized to an intervention group, receiving a treadmill workstation and encouraging emails, or to a control group, continuing to work as usual. Effects on cognitive function, hippocampal volume, prefrontal cortex (PFC) thickness, and circulating brain-derived neurotrophic factor (BDNF) were analyzed. Further, mediation analyses between changes in walking time and light-intensity physical activity (LPA) on changes in BDNF and hippocampal volume between baseline and 13 months, and multivariate analyses of the baseline data with percentage sitting time as the response variable, were performed. Results: No group by time interactions were observed for any of the outcomes. In the mediation analyses, positive associations between changes in walking time and LPA on changes in hippocampal volume were observed, although not mediated by changes in BDNF levels. In the multivariate analyses, a negative association between percentage sitting time and hippocampal volume was observed, however only among those older than 51 years of age. Conclusion: Although no group by time interactions were observed, our analyses suggest that increased walking and LPA may have positive effects on hippocampal volume and that sedentary behavior is associated with brain structures of importance for memory functions.
