Compensatory and overcompensatory dynamics in prey–predator systems exposed to harvest
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-11)Density dependent prey–predator systems under the impact of harvest are considered. The recruitment functions for both the prey and predator belong to the Deriso–Schnute family which allow us to study how the dynamical behaviour of both populations changes when compensatory density dependence turns overcompensatory. Depending on the degree of overcompensation, we show in the case of no harvest that ... -
Aerodynamic forces on iced cylinder for dry ice accretion – A numerical study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-28)Within this paper the ISO 12494 assumption of standard of slowly rotating reference collector under ice accretion has been tested. This concept, introduced by (Makkonen, 1984), suggests that the power line cables, which are the basis of the “reference collector” in the ISO framework, are slowly rotating under ice load, due to limited torsional stiffness. For this purpose, several Computational Fluid ... -
Farsfigurer, skeive døtre og voldens egendynamikk i "The Last of Us: Part II"
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-26)Denne artikkelen gir en fortolkning av Naughty Dogs skytespill <i>The Last of Us: Part II</i> (2020). Med utgangspunkt i Judith Butlers kritikk av krigsdiskurser viser jeg hvordan spillet rekalibrerer kjønnsnormer, undergraver skytesjangerens konvensjoner og fremtvinger en kritisk granskning av vold og eskalering. Gjennom måten spillet avslører voldens ødeleggende egendynamikk og introduserer skeive ... -
The kaolinite shuttle links the Great Oxidation and Lomagundi events
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-19)The ~2.22–2.06 Ga Lomagundi Event was the longest positive carbon isotope excursion in Earth’s history and is commonly interpreted to reflect perturbations in continental weathering and the phosphorous cycle. Previous models have focused on mechanisms of increasing phosphorous solubilization during weathering without focusing on transport to the oceans and its dispersion in seawater. Building from ... -
Valuing the ecosystem service benefits from kelp forest restoration: A choice experiment from Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-08)Habitat loss and degradation are recognised as the most important causes of species decline and extinction in marine ecosystems. It is also widely recognised that a range of restoration actions are now essential to halt further decline. From a policy perspective, demonstration that restoration activity is in the interest of society is an important goal. In this paper, the welfare impacts of restoring ... -
Isolerte samfunn? Spanskesyken i Kautokeino og Karasjok (1918-20)
(Mastergradsoppgave; Master thesis, 2021-05-16)Spanskesyken er estimert til å ha tatt livet av mellom 50 og 100 millioner mennesker. Tidligere forskning har vist at hvor dødelig denne pandemien var, varierte mye mellom folkegrupper og geografiske områder. I denne oppgaven er det sett nærmere på individdata for mortaliteten i Kautokeino og Karasjok under spanskesyken årene 1918-20. Aldersfordelingen av dødeligheten er undersøkt med utgangspunkt ... -
Landfast for ein kvar pris?
(Mastergradsoppgave; Master thesis, 2021-05-14)At distriktspolitikk og samferdslepolitikk går hand i hand er ein etablert oppfatning, men korleis står distriktspolitiske omsyn opp mot samfunnsøkonomiske vurderingar? Denne oppgåva drøftar korleis desse omgrepa står opp mot kvarandre i samferdslepolitikken. Denne oppgåva tek føre seg ferjeavløysingsprosjektet Ryfast og ser nærmare på korleis distriktspolitiske omsyn og samfunnsøkonomiske vurderingar ... -
Fornorskningens pedagogiske vending
(Mastergradsoppgave; Master thesis, 2021-05-14)Denne masteroppgaven omhandler fornorskningspolitikken i skolen i perioden 1935-1963. Det undersøkes hvordan den pedagogiske vitenskapen og det politiske regimet fra midten av 1930-tallet utformet og planla et omslag i fornorskningspolitikken i den språkblandede skolen. Margrethe Wiigs samiske abc-bok (utgitt 1951) brukes for å synliggjøre sammenhengene mellom vitenskapen og politikken samtidig som ... -
Fra Hammerfest pleiehjem til Åsgård sykehus
(Mastergradsoppgave; Master thesis, 2021-06-01)Oppgaven skildrer utviklingen av sinnssykevesenet i Finnmark i perioden 1920-1961. Utgangspunktet for oppgaven er Stortingets behandling av et nytt statsasyl i Troms og Finnmark. Da statsasylet ble utsatt i 1925, først og fremst av økonomiske årsaker, bestemte Finnmark fylke seg for å etablere et eget pleiehjem ved Fuglenes i Hammerfest. I pleiehjemmet, som ble kalt HPH, 12 år lange drift, opparbeidet ... -
Rejecting Non-Paternalist Motivation: An Experimental Test
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-29)Is people’s willingness to implement their fairness views on a group dependent on how many in the group share their view? We designed a new experiment to answer this question. Spectator participants were asked how many other participants they believe share their view of whether it is fair to redistribute income in a work task. They were then given the option to pay two cents to implement the ... -
Two hundred years of zooplankton vertical migration research
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)Vertical migration is a geographically and taxonomically widespread behaviour among zooplankton that spans across diel and seasonal timescales. The shorter-term diel vertical migration (DVM) has a periodicity of up to 1 day and was first described by the French naturalist Georges Cuvier in 1817. In 1888, the German marine biologist Carl Chun described the longer-term seasonal vertical migration ... -
Humpback Whale (Megaptera novaeangliae) Song on a Subarctic Feeding Ground
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-24)Male humpback whales (Megaptera novaeangliae) are known to produce long complex sequences of structured vocalizations called song. Singing behavior has traditionally been associated with low latitude breeding grounds but is increasingly reported outside these areas. This study provides the first report of humpback whale songs in the subarctic waters of Northern Norway using a long-term bottom-moored ... -
Enhanced Arctic stratification in a warming scenario: Evidence from the mid pliocene warm Pperiod
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-10)Global warming is most pronounced in the Arctic as evident from the massive sea ice loss during the past few decades. The Mid-Pliocene Warm Period (MPWP), 3.264 – 3.025 million years ago with similar CO2 levels, is the nearest analogue for understanding the impacts of future global warming. High-resolution studies of relative nutrient utilization and productivity from the Atlantic-Arctic Gateway ... -
Study of the in-cloud dry ice accretion on cylinders for low values of the Stokes number
(Doctoral thesis; Doktorgradsavhandling, 2021-08-31)The study of the atmospheric ice accretion has received some attention from the scientific community in the past, with the available knowledge spanning from the works of the Langmuir and Blodgett (1946) on the Mt. Washington Observatory till the analytical parameterization of the Finstad et al. (1988), with the latter being the current analytical benchmark and the integral part of the ISO 12494 ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-20)The polar cod (Boreogadus saida) and the Antarctic silverfish (Pleuragramma antarctica) are pelagic fish endemic to the Arctic and Antarctica sea, respectively. Both species are abundant and play a central role as midtrophic wasp-waist species in polar ecosystems. Due to their biological and ecological characteristics (small size, complex life histories, relatively short generation cycles, movement ... -
A distributed time-lapse camera network to track vegetation phenology with high temporal detail and at varying scales
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-29)Near-surface remote sensing techniques are essential monitoring tools to provide spatial and temporal resolutions beyond the capabilities of orbital methods. This high level of detail is especially helpful to monitor specific plant communities and to accurately time the phenological stages of vegetation – which satellites can miss by days or weeks in frequently clouded areas such as the Arctic. In ... -
Business incubator management and entrepreneur collaboration with R&D milieus: Does the regional context matter?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-05)We study whether business incubator management collaboration with R&D milieus affects incubated entrepreneurs to also collaborate with R&D milieus in different regional contexts. Empirically, we analyse 281 Norwegian entrepreneurs in 32 different business incubators. Incubator collaboration with R&D milieus increases entrepreneur collaboration with R&D milieus in sparsely but not densely populated ... -
Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-10)Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, we use a molecular method of identification, a species-specific polymerase chain reaction, to provide the first description of the seasonal dynamics and life histories of the ... -
Fat storage influences fasting endurance more than body size in an ungulate
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-26)<ol> <li>The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and food restricted environment, but contrary to predictions from the FEH, empirical evidence shows that Arctic mammals are often smaller than their temperate conspecifics. ... -
Intimate partner violence and its association with mental health problems: The importance of childhood violence – The SAMINOR 2 Questionnaire Survey
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-30)Aims: This study aims to estimate the prevalence of intimate partner violence (IPV) and its association with psychological distress and symptoms of post-traumatic stress (PTS) among Sami and non-Sami and to explore whether the association between IPV and mental health is modified by exposure to childhood violence (CV). These issues are scarcely studied among the Sami. Methods: This study was based ...
