    • Relations between Sámi and Western ways of sorting and organizing elements in a set 

      Fyhn, Anne Birgitte; Steinfjell, Ann Synnøve (Journal article; Tidsskriftartikkel; Peer reviewed, 2023)
      This paper describes three examples of Sámi mathematics. These examples, which are associated with different cultural contexts, show similarities to what Western mathematics calls 'combinatorics’. All examples are cultural practices that show descriptive use of mathematical knowledge. These are not mathematical problems and thus there is no need to find an exact number of possibilities. We describe ...

      Jorda Molina, Eric; Sen, Arunima; Bluhm, Bodil Annikki Ulla Barbro; Renaud, Paul Eric; Włodarska-Kowalczuk, Maria; Legeżyńska, Joanna; Oleszczuk, Barbara; Reiss, Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      The Barents Sea has been coined ‘the Arctic hotspot’ of climate change due to the rapidity with which environmental changes are taking place. This transitional domain from Atlantic to Arctic waters is home to highly productive benthic communities. This system strongly fluctuates on a seasonal basis in its sympagic-pelagicbenthic coupling interactions, with potential effects on benthic standing ...
    • Rich local knowledge despite high transience in an Arctic community experiencing rapid environmental change 

      Lennert, Ann Eileen; van der Wal, René; Zhang, Jasmine; Hausner, Vera Helene; Ancin Murguzur, Francisco Javier; Miles, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-04)
      Environmental monitoring and long-term research produce detailed understanding, but its collective effort does not add up to ‘the environment’ and therefore may be difficult to relate to. Local knowledge, by contrast, is multifaceted and relational and therefore can help ground and complement scientific knowledge to reach a more complete and holistic understanding of the environment and changes ...
    • New marine low trophic resources as food: nutritional and food safety aspects 

      Elvevoll, Edel Oddny; Eilertsen, Karl-Erik; Aschan, Michaela Maria; Bandarra, Narcissa (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-01)
      Food agencies recommend increasing the consumption of aquatic food to promote healthy living and sustainability, and, particularly, to prevent Western lifestyle-related diseases and secure sustainable food systems.

    • The intraspecific diversity of Norwegian Arctic charr (Salvelinus alpinus (L.)): An examination of repeatability and life history 

      Grenier, Gabrielle (Doctoral thesis; Doktorgradsavhandling, 2023-11-24)
      Across Arctic charr’s Holearctic distribution we see repeated patterns where multiple ecotypes diverge along ecological resource gradients. Arctic charr occur in both anadromous and lacustrine forms. Furthermore, lacustrine ecotypes are seen repeatedly specializing their morphology, trophic ecology, and life history along a benthic pelagic axis and along the depth gradient. Typically, a pelagic ...

    • Who cares? Effects of gendered self-perceptions on dropout intentions in communal degree programs 

      Olsen, Marte; Parks-Stamm, Elizabeth J.; Hansen Lund, Ingvild Marie; Martiny, Sarah Elisabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-12)
      Global population aging trends create an increased need for educated workers in the health domain. At the same time, communal degree programs (i.e., health care and early education [HEE]) show high dropout rates—particularly for men. Extending person-environment fit theory and the lack of fit model, we investigate whether students' (gendered) self-perceptions relate to perceived fit and whether fit ...
