      Brynjulfsen, Runar Reitan; Brynjulfsen, Henning Reitan (Master thesis; Mastergradsoppgave, 2024-06-01)
      Denne masteroppgaven undersøker hvorvidt maskinlæring kan utkonkurrere kjøp-og-hold-strategier i de nordiske aksjemarkedene. Arbeidet omfatter en komparativ studie av forskjellige maskinlæringsteknikker brukt til å forutsi aksjemarkedsbevegelser. Problemstillingen er: "Har maskinlæringsteknikker en god prediksjonsevne på nordiske aksjeindekser med lengre intervaller?" Random forest, kunstige nevrale ...
    • Potensielle fusjoner av nettselskaper i Nord-Norge 

      Berg, Christoffer Gamst; Vaagen, Andréas Hoffmann (Master thesis; Mastergradsoppgave, 2024-06-03)
      Denne studien analyserer potensielle fusjoner mellom nettselskaper i Nord-Norge, for å undersøke hvordan fusjonene påvirker konkurransedyktigheten til de gitte selskapene i NVEs reguleringsmodell. For å danne fusjonspartnere blir forholdstall mellom input- og outputvariablene brukt, med mål om å finne partnere som i stor grad er ulike. Datagrunnlaget for analysen er hentet fra beregningen av ...

    • Unlocking the potential of sedimentary ancient DNA 

      Elliott, Lucas Dane (Doctoral thesis; Doktorgradsavhandling, 2024-11-15)
      Past ecosystem dynamics provide valuable information to inform current and future management. Ancient DNA has rapidly become a powerful tool in uncovering these lost environments. We demonstrate the ecological inferences made possible by metabarcoding analysis on sedimentary ancient DNA by investigating the role climate and glacial activity have had on a catchment’s vegetation community. We identified ...
    • Capture and Release of Minke Whales Offers New Research Opportunities, Including Measurements of Mysticete Hearing 

      Kleivane, Lars; Kvadsheim, Petter Helgevold; Vinje, Anna Victoria Pyne; Mulsow, Jason; Ølberg, Rolf-Arne; Teilmann, Jonas; Harms, Craig; Houser, Dorian (Journal article; Tidsskriftartikkel; Peer reviewed, 2024)
      Knowledge about species-specific hearing is vital to assessing how anthropogenic noise impacts marine mammals. Unfortunately, no empirical audiogram exists for any mysticete whale. We therefore developed a catch-and-release method to assess hearing in a small mysticete, the minke whale (Balaenoptera acutorostrata). Stationary lead nets were placed to intercept migratory routes and direct the whales ...

      Howell, Daniel; Aune, Magnus; Bogstad, Bjarte; Chetyrkin, Anatoly; Fall, Johanna Jennifer Elisabeth; Filin, Anatoly; Godiksen, Jane Aanestad; Hallfredsson, Elvar Halldor; Johannesen, Edda; Kovalev, Yuri; Mikhailov, Andrey; Russkikh, Alexey; Stesko, Aleksi; Vasilyev, Dmitri; Vihtakari, Mikko; Vollen, Tone; Windsland, Kristin; Yaragina, Natalia A. (Research report; Forskningsrapport, 2024-06-21)
      On 30th March 2022 all Russian participation in ICES was temporally suspended. Although the announcement of the suspension stressed the role of ICES as a “multilateral science organization”, this suspension applied not only to research activities, but also to the ICES work providing fisheries advice for the sustainable management of fish stocks and ecosystems. As a result of the suspension, the ICES ...

    • The Arsenal of Democracy? An Examination of Political Regime Types’ Success in the Global Sporting Arms Race Following the Collapse of the Iron Curtain 

      Storm, Rasmus K.; Jakobsen, Tor Georg (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-08)
      Over the years, international elite sport has developed into an 'arms race' with the success of national elite sport systems becoming a symbol of regime superiority. During the Cold War, the Eastern and Western Blocs battled for success in various sports disciplines. The former nations were dominating in terms of medals, symbolising the force of the socialist autocratic system. However, because of ...
    • Strongly asymmetric interactions and control regimes in the Barents Sea: a topological food web analysis 

      Jordán, Ferenc; Capelli, Greta; Primicerio, Raul; Bodini, Antonio (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-22)
      Introduction: Increasing temperature of the global ocean alters the spatial behavior of a number of species. From the northern Atlantic Ocean, species may shift their area towards the poles. This results in the atlantification of the Barents Sea, raising questions about possible changes in species composition, community structure and community control.<p> <p>Methods: We address the question ...

    • Putting an artificial intelligence‐generated label on it comes naturally 

      Sigurdsson, Valdimar; Larsen, Nils Magne; Folwarczny, Michal; Dubois, Magalie; Fagerstrøm, Asle (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-10)
      Climate change and the advent of artificial intelligence-generated content are reshaping wine marketing. The interplay between consumer focus on naturalness and sustainable farming practices and the proliferation of artificial intelligence-generated content represents a particularly salient area of research. However, the extent to which the presence of fictitious artificial intelligence-generated ...
    • Destination design: identifying three key co-design strategies 

      Smit, Bert; Melissen, Frans; Font aulet, Xavier; Dickinger, Astrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-27)
      Collaborative approaches to destination design require conscious and reflexive stakeholder involvement in activities and decision making. Design science studies such participatory processes by observing design teams in practice. From these observations, scientists have identified design strategies and processes that design teams use to support their work in identifying problems and developing ...
    • Sex-specific overdominance at the maturation vgll3 gene for reproductive fitness in wild Atlantic salmon 

      Mobley, Kenyon Brice; Barton, Henry J.; Ellmén, Mikko; Ruokolainen, Annukka; Guttorm, Olavi; Pieski, Hans; Orell, Panu; Erkinaro, Jaakko; Primmer, Craig R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-15)
      Linking reproductive fitness with adaptive traits at the genomic level can shed light on the mechanisms that produce and maintain sex-specific selection. Here, we construct a multigenerational pedigree to investigate sex-specific selection on a maturation gene, vgll3, in a wild Atlantic salmon population. The vgll3 locus is responsible for ~40% of the variation in maturation (sea age at first ...

    • Impact evaluation with process tracing: explaining causal processes in an EU-interreg sustainable tourism intervention 

      Montano, Luigina Jessica; Elsenbroich, Corina; Font aulet, Xavier; Ribeiro, Manuel Alector (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-11)
      Drawing from the field of complex evaluations we discuss a novel application of process tracing for the evaluation of complex tourism interventions. We argue that to better evidence impact of tourism interventions and facilitate policy transfer we ought to adopt approaches to evaluation that allow us to deepen our understanding of causal mechanisms at play in an intervention. We adopt process ...
