  • Public entrepreneurial opportunities: How institutional logics shape public servants' opportunity evaluation 

    Gullmark, Petter; Clausen, Tommy Høyvarde; Gümüsay, Ali Aslan; Alsos, Gry Agnete (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-26)
    Which entrepreneurial opportunities do public servants find appealing, and what influences their evaluation? Our investigation of 14 Norwegian municipal entrepreneurial projects indicates that public servants positively assess the attractiveness of welfare, economic, and participatory opportunities. Their evaluations are shaped by public sector logics. Our contribution is twofold: first, we connect ...

Accurate and sensitive quantification of eDNA is crucial for tracking rare and invasive species and understanding the biodiversity abundance and distribution of aquatic organisms. This study compares the sensitivity and ...
  • Goose grubbing and warming suppress summer net ecosystem CO2 uptake differentially across high-Arctic tundra habitats 

    Petit Bon, Matteo; Beard, Karen H.; Braathen, Kari Anne; Lee, Hanna; Jonsdottir, Ingibjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-09)
    Environmental changes, such as climate warming and higher herbivory pressure, are altering the carbon balance of Arctic ecosystems; yet, how these drivers modify the carbon balance among different habitats remains uncertain. This hampers our ability to predict changes in the carbon sink strength of tundra ecosystems. We investigated how spring goose grubbing and summer warming—two key environmental-change ...
  • The relationship between personal values and preference for novelty: conceptual issues and the novelty–familiarity continuum 

    Blomstervik, Ingvild Hansten; Olsen, Svein Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-20)
    The search for novelty when going on vacation is a prominent theme in the literature. Still, empirical research exploring the antecedents of this preference is limited. This study investigates the impact of two opposing personal value dimensions – openness to change and conservation – on individuals’ preference for novelty and familiarity. Data was assembled from a representative sample of 493 UK ...

    Probiotics, known for their health benefits as living microorganisms, hold significant importance across various fields, including agriculture, aquaculture, nutraceuticals, and pharmaceuticals. Optimal delivery and storage of probiotic cells are essential to maximize their effectiveness. Biopolymers, derived from living sources, plants, animals, and microbes, offer a natural solution to enhance ...
  • Investment and endogenous efficiency in a contest 

    Clark, Derek John; Kundu, Tapas; Nilssen, Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-01)
    Contests are ubiquitous but do not happen in a vacuum. Rivals can prepare themselves for the contest to improve their ultimate chance of victory. Two contestants with different prize values play an all-pay auction and can invest to improve the efficiency of their own effort in the contest. We show that at most one player will invest, and that two asymmetric pure-strategy equilibria exist depending ...

This study characterizes the canal’s water using physicochemical parameters to evaluate its suitability for different uses. Water samples ...
  • Transcriptomic profiling of gill biopsies to define predictive markers for seawater survival in farmed Atlantic salmon 

    Grønvold, Lars; van Dalum, Mattis J.; Striberny, Anja; Manous, Domniki; Ytrestøyl, Trine; Mørkøre, Turid; Boison, Solomon Antwi; Gjerde, Bjarne; Jørgensen, Even; Sandve, Simen Rød; Hazlerigg, David Grey (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-16)
    Wild Atlantic salmon migrate to sea following completion of a developmental process known as parr-smolt transformation (PST), which establishes a seawater (SW) tolerant phenotype. Effective imitation of this aspect of anadromous life history is a crucial aspect of commercial salmon production, with current industry practice being marred by significant losses during transition from the freshwater ...
  • Social acceptance for salmon produced in new production systems - Report on willingness to pay for new production systems and social acceptance of salmon farming in general

    This report summarizes the findings from a price experiment survey on the willingness to pay (WTP) for salmon produced using new production systems in salmon farming in three countries (Norway, Canada and Scotland). This includes land-based, floating closed containment cages and offshore production systems. The results revealed that consumers preferred salmon produced using conventional (traditional) ...
  • Altruisme versus egennytte: Motivasjonen bak sykepleierstudenters studievalg 

    Borge, Baard Herman; Hagebakken, Grete; Lindrupsen, Cathrine; Thorsen, Sunniva Dahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-13)
    I denne artikkelen undersøker vi hva som, tross lave søkertall og negativ medieomtale, motiverer unge mennesker til å studere sykepleie. Studien setter søkelys på skillet mellom altruistisk og egennyttig motivasjon, og sammenligner dessuten sykepleiestudenter på bakgrunn av deres kjønn, alder, tidligere arbeidserfaring og hvilken prioritet de ga studiet da de søkte. Kvantitative data ble samlet ...
  • Loss of pelagic fish and zooplankton density associated with subglacial upwelling in high Arctic estuaries may be mitigated by benthic habitat expansion following tidewater glacier retreat 

    Gonzalez Triginer, Victor; Sen, Arunima; Geoffroy, Maxime; Damsgård, Børge (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-23)
    Glacier fronts are hotspots of pelagic productivity due to upwelling of nutrient-rich water. As tidewater glaciers retreat into land, this subglacial circulation will disappear and sedimentation from terrestrial runoff will increase, leading to a decrease in pelagic productivity with a decline in the abundance of fish and zooplankton. We used Billefjorden, a high Arctic fjord with a glacier recently ...
  • Bycatch of northern fulmar (Fulmarus glacialis) in Norwegian longline fisheries: Assessing spatiotemporal variations in scale and risk to improve management 

    Clegg, Tom L.; Christensen-Dalsgaard, Signe; Bråthen, Vegard Sandøy; Tarroux, Arnaud; Danielsen, Jóhannis; Descamps, Sebastien; Follestad, Arne; Hallgrimsson, Gunnar Thor; Helberg, Morten; Helgason, Hálfdán H.; Jónsson, Jón Einar; Kolbeinsson, Yann; Strøm, Hallvard; Thompson, Paul; Thórarinsson, Thorkell Lindberg; Williams, Tom; Bærum, Kim Magnus (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-09)
    Seabirds are vulnerable to bycatch in longline fisheries but for most species the impacts are largely unknown. To address this knowledge gap, studies can estimate bycatch directly using observations or calculate the theoretical risk of bycatch using overlap indexes. Here we quantify the scale and risk of bycatch of northern fulmar (Fulmarus glacialis) in the Norwegian offshore longline fishery using ...

Herunder er det studier som peker på at invalidering har negativ effekt for emosjonell ...
  • Ghost fishing by self-baited lost, abandoned or discarded pots in snow crab (Chionoecetes opilio) fishery 

    Cerbule, Kristine; Herrmann, Bent; Larsen, Roger Bertram; Yu, Mengjie (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-14)
    Unintended continuous capture or so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear produces negative environmental impact on marine life and nature conservation. The risk of ghost fishing in pots could be high due to potential self-baiting resulting from mortality of ghost fished catch. Self-baiting may increase ghost fishing by further attracting marine organisms, ...
  • Beyond Green Promises: How Concrete Information Sparks Pride and Drives Sustainable Fashion 

    Arnesen, Sarah Lisa; Larsen, Nils Magne; Wien, Anders Hauge (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-05)
    This study examines the relationship between trust and pride and their collective influence on sustainable consumption within the fashion industry. We hypothesized that concrete marketing communications would enhance consumer trust, which in turn would directly, and indirectly via increased pride, encourage sustainable consumption intentions. Through an experimental design involving 199 participants, ...

    Lupini, Sara (Peer reviewed; Chapter; Bokkapittel, 2024)
    There is an urgent need to promote a sustainable entrepreneurial mindset in Higher Education (HE) across fields and disciplines, to address the deficit of new and innovative value creation activities and bring about necessary transformations towards sustainability. This can be strategically achieved by educating new generations of entrepreneurs in tackling the sustainability challenges of our times ...
  • Taking the beat of the Arctic: are lemming population cycles changing due to winter climate? 

    Gauthier, Gilles; Ehrich, Dorothee; Belke-Brea, Maria; Dominé, Florent; Alisauskas, Ray; Clark, Karin; Ecke, Frauke; Eide, Nina Elisabeth; Framstad, Erik; Frandsen, Jay; Gilg, Olivier; Henttonen, Heikki; Hörnfeldt, Birger; Kataev, Gennadiy D.; Menyushina, Irina E.; Oksanen, Lauri; Oksanen, Tarja Maarit; Olofsson, Johan; Samelius, Gustaf; Sittler, Benoit; Smith, Paul A.; Sokolov, Aleksandr A.; Sokolova, Natalia A.; Schmidt, Niels M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-14)
    Reports of fading vole and lemming population cycles and persisting low populations in some parts of the Arctic have raised concerns about the spread of these fundamental changes to tundra food web dynamics. By compiling 24 unique time series of lemming population fluctuations across the circumpolar region, we show that virtually all populations displayed alternating periods of cyclic/non-cyclic ...
  • The rural development trilemma 

    Vik, Jostein; Johnsen, Jahn Petter; Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-30)
    Rural public policies are important and contested in many countries. Politicians and administrations often have high ambitions for both spatial policies (e.g. maintaining demography, local work, businesses etc.) technological development (modernisation, increased productivity etc.), while production tend to be limited by markets (as in the case of agricultural productions) or resources (as in e.g. ...
  • Redescription of Proteocephalus fallax La Rue, 1911 (Cestoda) and a list of proteocephalid tapeworms of whitefish (Coregonus spp.) 

    Scholz, Tomáš; de Chambrier, Alain; Brabec, Jan; Knudsen, Rune; Costa, Isabel Blasco (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-22)
    Tapeworms of the genus Proteocephalus Weinland, 1858 (Cestoda: Proteocephalidae) are common and widespread intestinal parasites of whitefish (Coregonus spp., Salmonidae: Coregoninae). Previous taxonomic studies, based solely on morphology and inconsistently fixed specimens, concluded that all salmoniform fish, including whitefish, are parasitised by a single euryxenous and highly polymorphic ...
  • The challenge of harvesting common sole (Solea solea) in highly selective trawl fisheries 

    Frandsen, Rikke Petri; Krag, Ludvig Ahm; Herrmann, Bent (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-28)
    Common sole (Solea solea) is an economically important species in several European trawl fisheries, yet little is known about the size selective properties of codends used in bottom trawl fisheries targeting sole. This study presents results from a sea trial conducted in the inner Danish waters where common sole is fished in a seasonal trawl fishery using a 90 mm diamond mesh codend with a mandatory ...
