    • On the Heat and Wave Equations with the Sturm-Liouville Operator in Quantum Calculus 

      Shaimardan, Serikbol; Persson, Lars-Erik; Tokmagambetov, Nariman (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-19)
      In this paper, we explore a generalised solution of the Cauchy problems for the q-heat and q-wave equations which are generated by Jackson’s and the q-Sturm-Liouville operators with respect to t and x, respectively. For this, we use a new method, where a crucial tool is used to represent functions in the Fourier series expansions in a Hilbert space on quantum calculus. We show that these solutions ...
    • Salmon-lice as a potential threat to anadromous Arctic charr populations 

      Rochat, Eloïse Coralie; Grenier, Gabrielle; Muladal, Rune; Jensen, Hallvard; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-25)
      Salmon-lice have the potential to change the behaviour and growth of their salmonid host species. Here, the baseline infection levels of salmon-lice of post-smolts (n = 815) and veteran migrants (n = 875) of sea-run Arctic charr (Salvelinus alpinus Linnaeus, 1758) were monitored over two successive years in a sub-Arctic Norwegian fjord without farming of salmonids. All Arctic charr were collected ...
    • Verbal instructions as selection bias that modulates visual selection 

      Damanskyy, Yevhen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-15)
      Research has shown that in addition to top-down and bottom-up processes, biases produced by the repetition priming effect and reward play a major role in visual selection. Action control research argues that bidirectional effect-response associations underlie the repetition priming effect and that such associations are also achievable through verbal instructions. This study evaluated whether verbally ...
    • Selling the indigenous in Nordic welfare states: examples from Norway and Sweden 

      Olsen, Kjell; Pashkevich, Albina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-26)
      Indigenous peoples’ right to control representations of their own culture and heritage is unquestionable, but in the case of tourism activities other stakeholders’ understandings come into play. The nation-state is still an important organizational foundation for tourism. For the Indigenous Sámi people, who are located in four different nation-states, national destination management organizations ...
    • Contact with parents from childhood to adulthood – a longitudinal study of children in kinship care and non-kinship care 

      Skoglund, Jeanette; Mabille, Geraldine; Thørnblad, Renee (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-12)
      Previous research on parental contact for children in foster care shows that contact frequency is significantly related to parent’s gender and placement type. Yet very few studies have explored the impact of gender and type of placement on parental contact over time. Based on longitudinal quantitative data from kinship care and non-kinship care placements in Norway, we analyse contact between children ...

      Remili, Anaïs; Dietz, Rune; Sonne, Christian; Samarra, Filipa I. P.; Rikardsen, Audun H.; Kettemer, Lisa Elena; Ferguson, Steven H.; Watt, Cortney A.; Matthews, Cory J. D.; Kiszka, Jeremy J.; Jourdain, Eve Marie; Borgå, Katrine; Ruus, Anders; Granquist, Sandra M.; Rosing-Asvid, Aqqalu; McKinney, Melissa A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding ecology of these apex predators remains poorly understood. <p>Here, we use our newly validated quantitative fatty acid signature analysis (QFASA) approach on nearly 200 killer whales and over 900 potential prey to model ...
    • Traces of an Arctic Voice: The Portrait of Qalaherriaq 

      Høvik, Ingeborg; Jeremiassen, Axel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-09)
      This article analyses the portrait of the young Inughuit hunter Qalaherriaq, who was brought involuntarily to England from his home in Perlernerit (Cape York) in today's Kalaallit Nunaat (also known as Greenland) with Captain Erasmus Ommanney’s expedition vessel in 1851. The portrait’s highly unconventional representation, wherein the sitter is shown both en face and in profile, betrays an interest ...

    • Enemy image? A comparative analysis of the Russian federation’s role and position in the leading national security documents of Estonia and the Czech Republic 

      Bartoszewicz, Monika Gabriela; Prucková, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-14)
      States are security-seekers vis-a-vis ‘significant others’ who are cast as enemies in the international system. Usually, the study of the enemy image is connected with relative equilibrium concerning power capabilities. Less attention was given to a situation of a decisive power imbalance. Thus, a question arises whether such a situation will lead to a uniform enemy image? Concomitantly, what is the ...
    • Corto Maltese and the Myriad Narratives of a More-than-Human Ocean: Revisiting Some of UNCLOS’ Ontological Assumptions 

      Tsiouvalas, Apostolos (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-12)
      Graphic novels have been previously recognized by scholarly research as a valuable conceptual lens for thinking critically about law. Asserting the need for a deeper engagement with the material foundations, ontological beliefs and epistemological grids that lie under the development of international law of the sea, this article delves into the imaginary oceanic universe of Hugo Pratt’s classic ...
    • The arctic migration route: local consequences of global crises 

      Paulgaard, Gry; Soleim, Marianne Neerland (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-27)
      This paper addresses peace education focusing on how place-based experiences and collective memories stimulate local mobilisation for refugees fleeing from war. The Arctic Migration Route, located above 69th degree north, became an alternative to dangerous boat trips on the Mediterranean Sea, for people seeking safety and protection in the fall of 2015. During a few months, over 5,500 people from ...
    • RELAX: Representation Learning Explainability 

      Wickstrøm, Kristoffer; Trosten, Daniel Johansen; Løkse, Sigurd Eivindson; Boubekki, Ahcene; Mikalsen, Karl Øyvind; Kampffmeyer, Michael; Jenssen, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-11)
      Despite the significant improvements that self-supervised representation learning has led to when learning from unlabeled data, no methods have been developed that explain what influences the learned representation. We address this need through our proposed approach, RELAX, which is the first approach for attribution-based explanations of representations. Our approach can also model the uncertainty ...
    • Mathematics teaching in lávvues from the perspectives of Indigenous education and critical peace education 

      Nordkild, Siv Ingrid; Hætta, Ole Einar Isaksen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-04)
      This study focuses on how teaching is affected when two cultures meet: the Sámi culture, represented by the lávvu, and the culture of teaching mathematics in a school. It describes the use of the lávvu (a Sámi temporary dwelling) as a classroom for teaching mathematics. For several years, and in cooperation with researchers, the teachers at the Guovdageaidnu Lower Secondary Schoolg have been developing ...
    • Preconditioning of Summer Melt Ponds From Winter Sea Ice Surface Temperature 

      Thielke, Linda; Fuchs, Niels; Spreen, Gunnar; Tremblay, Bruno; Birnbaum, Gerit; Huntemann, Marcus; Hutter, Nils; Itkin, Polona; Jutila, Arttu; Webster, Melinda A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-22)
      Comparing helicopter-borne surface temperature maps in winter and optical orthomosaics in summer from the year-long Multidisciplinary drifting Observatory for the Study of Arctic Climate expedition, we find a strong geometric correlation between warm anomalies in winter and melt pond location the following summer. Warm anomalies are associated with thinner snow and ice, that is, surface depression ...

      Bartoszewicz, Monika Gabriela; Pavlíčková, Kristýna (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-06)
      The role of the North Atlantic Treaty Organization and its influence on the peace and conflict dynamic in the Middle East has always been a discussed and controversial issue. While the United States and the countries of the NATO Southern flank are active in the discussions on NATO engagement in the region, the perspectives of NATO Eastern flank countries is often forgotten. This work contributes to ...
    • The Antarctic Peninsula: Argentina and Chile in the era of global change 

      Vidal, Florian (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-09)
      While Argentine-Chilean relations have long been swayed between cooperation and confrontation since their independence in the 19<sup>th</sup> century and a long-standing presence in Antarctica, the stretch between Tierra del Fuego to the Antarctic Peninsula stands as the closest lane (i.e. about 1,000 km) to any other continent. Despite their territorial dispute over islands on the fractured southern ...
    • Assessing the impact of environmental variability on harvest in a heterogeneous fishery: a case study of the Canadian lobster fishery 

      Wright, Dana Elizabeth; Liu, Yajie (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-11)
      Global fisheries face significant challenges in the coming years due to climate change. Understanding and anticipating the impacts of climate change is a necessity for implementing appropriate fisheries management. This study uses a panel dataset of individual fishing vessels to examine how variation in ocean temperature affects fish harvest. Using the American lobster (Homarus americanus) fishery ...
