    • Governing the fisher body – safety as body-politics and fisheries governance 

      Sønvisen, Signe Annie; Thorvaldsen, Trine; Johnsen, Jahn Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-12)
      Body Mass Index (BMI) is not only the prevailing tool used for defining and diagnosing obesity, but it is also a tool that intervenes into fisheries governance, and into fishers’ lives and bodies. All fishers on board vessels over 100 gross tons (GT) must hold a seaman’s licence; too high a BMI may lead to a “loss-of-licence” and the inability to undertake their occupation. From a governmentality ...

    • Terra nullius, Inuit Habitation and Norse Occupation with Special Emphasis on the 1933 East Greenland Case 

      Ørebech, Peter Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05)
      Sovereignty acquired by occupation entails “recognize[d] title based on discovery,” “a reasonable period [of] … effective occupation of the region claimed to be discovered” and “the continuous and peaceful display of State authority.” Only terra nullius is subject to occupation. A territory inhabited by indigenous groups that sustain social and political organization may impede an occupying power ...
