    • Observasjonell film og situasjonsanalyse. Nye muligheter for utvikling av antropologisk forståelse. 

      Arntsen, Bjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-19)
      Hvordan bidrar etnografisk film til antropologisk forståelse? Hva er likheter og forskjeller i perspektiver og metoder i etnografiske filmopptak og en mer konvensjonell antropologi? Film og tekst er to ulike representasjonsformer med ulike styrker og svakheter. Jeg vil her argumentere for at det i møtet mellom den i utgangspunktet tekstbaserte situasjonsanalysen, slik den formuleres av Manchesterskolen, ...

    • Japanese tourists’ relatedness and connectedness with nature 

      Prebensen, Nina Katrine; Lee, Young-Sook; Kim, Hyelin Lina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-15)
      Nature-based tourism continues to gain importance globally. Research on sustainability claims that disconnection between nature and humanity may contribute to the environmental problems that we face in the 21st century. It is, thus, quintessential to better understand the underlying variables for sustainable behaviour in a tourism context. Research suggests scales on nature relatedness (NRS) and ...
    • Cordilleran ice-sheet growth fueled primary productivity in the Gulf of Alaska, northeast Pacific Ocean 

      Müller, Juliane; Romero, Oscar; Cowan, Ellen A.; McClymont, Erin L.; Forwick, Matthias; Asahi, Hirofumi; März, Christian; Moy, Christopher M.; Suto, Itsuki; Mix, Alan; Stoner, Joseph (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-15)
      Fertilization of the ocean by eolian dust and icebergs is an effective mechanism to enhance primary productivity. In particular, high-nutrient, low-chlorophyll (HNLC) areas where phytoplankton growth is critically iron-limited, such as the subarctic Pacific Ocean and the Southern Ocean, are proposed to respond to increases in bioavailable Fe supply with enhanced phytoplankton productivity and carbon ...
    • Levonorgestrel-releasing intrauterine system use is associated with a decreased risk of ovarian and endometrial cancer, without increased risk of breast cancer. Results from the NOWAC Study 

      Jareid, Mie; Thalabard, Jean-Christophe; Aarflot, Morten; Bøvelstad, Hege Marie; Lund, Eiliv; Braaten, Tonje (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-02)
      <p><i>Objective</i>: Women with ovarian cancer have poor survival rates, which have proven difficult to improve; therefore primary prevention is important. The levonorgestrel-releasing intrauterine system (LNG-IUS) prevents endometrial cancer, and recent studies suggested that it may also prevent ovarian cancer, but with a concurrent increased risk of breast cancer. We compared adjusted risks of ...
