    • On the temporal evolution of turbopause altitude, 1996-2021, 70 N, 19 E 

      Hall, Chris; Nozawa, S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-04)
      Medium frequency radars with multiple receivers are able to track the movement of the interference pattern on the ground from echoes from irregularities in refractive index. In particular, refractive index in the mesosphere is determined by electron density – commonly known as the ionospheric D-region. Thus using this technique it is possible to determine winds in the height regime 70-90 km, ...
    • Not All Those Who Wander Are Lost – Responses of Fishers’ Communities to Shifts in the Distribution and Abundance of Fish 

      Papaioannou, Eva A.; Selden, Rebecca L.; Olson, Julia; McCay, Bonnie J.; Pinsky, Malin L.; St. Martin, Kevin John (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-05)
      As species respond to warming water temperatures, fishers dependent upon such species are being compelled to make choices concerning harvest strategies. Should they “follow fish” to new fishing grounds? Should they change their mix of target species? Should they relocate their operations to new ports? We examined how fishing communities in the Northeast United States —a hotspot of recent warming—have ...

    • How young people who had dropped out of high school experienced their re-enrolment processes 

      Ramsdal, Gro Hilde; Wynn, Rolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-20)
      The study followed the re-enrolment processes of six young people in Northern Norway who had dropped out of high school. Early in the re-enrolment process, the participants focused on their experiences with lack of inner motivation, lack of endurance, and confusion concerning what they wanted to do with their lives. Later in the process, participants described positive changes in their inner ...
    • Association of dog ownership with accelerometer-measured physical activity and daily steps in 70-year-old individuals: a population-based cross-sectional study 

      Ballin, Marcel; Antonsson, Oskar; Rosenqvist, Viktor; Nordström, Peter; Nordström, Anna Hava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-21)
      Background: Dog ownership (DO) has been associated with higher levels of self-reported walking and physical activity. However, compared to device-based measures, self-reported measures of physical activity may sufer from bias due to recall and social desirability. They are also incapable of quantifying light-intensity physical activity (LPA) and step volume, both of which may have important health ...

    • The predictors of general knowledge: Data from a Spanish megastudy 

      Buades-Sitjar, Francisco; Boada, Roger; Guasch, Marc; Ferré, Pilar; Hinojosa, Jose A.; Duñabeitia, Jon Andoni (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-06)
      Studies on sociodemographic data and crystallized intelligence have often struggled to recruit enough participants to achieve sufficient validity. However, the advent of the internet now allows this problem to be solved through the creation of megastudies. Yet, this methodology so far has only been used in studies on vocabulary size, while general knowledge, another key component of crystallized ...
    • Understanding why impact assessment fails; a case study of theory and practice from Wafi-Golpu, Papua New Guinea 

      Roche, Charles; Brueckner, Martin; Walim, Nawasio; Sindana, Howard; John, Eugene (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)
      From an instrumental or management perspective, impact assessment (IA) is a process of identifying impacts, finding solutions and achieving project approval. A recipient community, however, has a completely different perspective. For them the IA is about living with impacts, individually and collectively, perhaps over generations, and contested processes of self-determination, consultation and ...
    • Unseen existences: Stories of life from Venembeli, Papua New Guinea 

      Roche, Charles; Spencer, Rochelle; John, Eugene; Walim, Nawasio; Sindana, Howard (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-23)
      This article presents stories of life from Venembeli, a remote village in the hinterlands of Papua New Guinea. Caught up in a contentious mining development, villagers both long for and fear the development promised by global capitalism. But with a forty year development history, the proposed Wafi-Golpu mine has become the only lens through which the present or future is imagined and understood. We ...
    • From urban neighbourhood environments to cognitive health: a cross-sectional analysis of the role of physical activity and sedentary behaviours 

      Cerin, Ester; Barnett, Anthony; Shaw, Jonathan E.; Martino, Erika; Knibbs, Luke D.; Tham, Rachel; Wheeler, Amanda J.; Anstey, Kaarin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-23)
      <p><b>Background: </b> There is a dearth of studies on the effects of the neighbourhood environment on adults’ cognitive function. We examined how interrelated aspects of the built and natural neighbourhood environment, including air pollution, correlate with adults’ cognitive function, and the roles of physical activity and sedentary behaviours in these associations. <p><b>Methods:</b> We used ...
    • The Anti-DNA Antibodies: Their Specificities for Unique DNA Structures and Their Unresolved Clinical Impact—A System Criticism and a Hypothesis 

      Rekvig, Ole Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-11)
      Systemic lupus erythematosus (SLE) is diagnosed and classified by criteria, or by experience, intuition and traditions, and not by scientifically well-defined etiology(ies) or pathogenicity(ies). One central criterion and diagnostic factor is founded on theoretical and analytical approaches based on our imperfect definition of the term “The anti-dsDNA antibody”. “The anti-dsDNA antibody” holds an ...
    • The Alternative Complement Pathway Is Activated Without a Corresponding Terminal Pathway Activation in Patients With Heart Failure 

      Shahini, Negar; Bjørkelund, Elisabeth; Bendz, Christina; Massey, Richard J; Schjalm, Camilla; Halvorsen, Bente; Broch, Kaspar; Ueland, Thor; Gullestad, Lars; Nilsson, Per H.; Aukrust, Pål; Mollnes, Tom Eirik; Louwe, Maria Cornelia; Holt, Margrethe Flesvig; Michelsen, Annika E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-24)
      Objective: Dysregulation of the complement system has been described in patients with heart failure (HF). However, data on the alternative pathway are scarce and it is unknown if levels of factor B (FB) and the C3 convertase C3bBbP are elevated in these patients. We hypothesized that plasma levels of FB and C3bBbP would be associated with disease severity and survival in patients with ...

    • Vannforsyning og barnedødelighet i Tromsø omkring 1920 

      Thorvaldsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-22)
      I 1919 bygde Tromsø kommune en demning i Slettaelva på den fjellrike Kvaløya vest for byen som de neste par årene ble koblet via et undersjøisk rør til byens vannforsyningssystem for å øke vannmengden og bedre kvaliteten på byens drikkevann. Nyttårsaften 1921 ble kvaløyvannet trykksatt i Tromsø sentrum. For å undersøke hvilken effekt dette hadde på barnedødeligheten, ble medisinalberetningene og ...
