    • Armaments and ornaments: mate-guarding and the evolutionary roots of religion 

      Czachesz, Istvan (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-09-13)
      This article explores the connection between sexual selection and religion, locating the origins of religious behavior in mate guarding after the transition to terrestrial life in <i>Homo erectus</i> 1.8 million years ago. An important consequence of the transition was the emergence of a polygynous, multiple-family social structure, which gave rise to mate guarding as a successful strategy. Further, ...
    • Less is more: why all paradigms are defective, and why that is a good thing 

      Janda, Laura Alexis; Tyers, Francis Morton (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-21)
      Only a fraction of lexemes are encountered in all their paradigm forms in any corpus or even in the lifetime of any speaker. This raises a question as to how it is that native speakers confidently produce and comprehend word forms that they have never witnessed. We present the results of an experiment using a recurrent neural network computational learning model. In particular, we com- pare the ...

      <i>Background:</i> Major incidents affect us globally, and are occurring with increasing frequency. There is still no evidence-based standard regarding the best medical emergency response to major incidents. Currently, reports on major incidents are non-standardised and variable in quality. This pilot study examines the first systematic reports from a consensus-based, freely accessible database, ...
    • Barnets rett til en forsvarlig levestandard - utøvelse av skjønn i Nav og barneverntjeneste 

      Kane, Aina Aune; Neverdal, Sissel; Stenberg, Oddbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      Barn har menneskerettslig krav på en forsvarlig levestandard. Oppvekst i lavinntektsfamilier medfører risiko for utenforskap og generasjonsoverføring av fattigdom, og forebyggingsog bistandsansvar påligger ulike kommunale virksomhetsområder. Vår undersøkelse i barnevernstjeneste og Nav viser at barnets rettigheter kan hemmes og fremmes av ulike forhold. Skolers organisering av kostnadsmessige ...

      Results of observations of variations of temperature, electron concentration and total electron content of the high-latitude region of the ionosphere during its modification by powerful short radio waves of the heating complex EISCAT/Heating (Tromsø, Norway) according to signals of the GLONASS satellites and the incoherent scattering UHF EISCAT radar (Tromsø, Norway) have been provided. The geometry ...
    • Policy context as a factor of bias in the valuation of environmental goods – a dual-process theories perspective 

      Nikitina, Ekaterina (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-03-13)
      When ecosystem services value estimates are applied in the economic assessment of environmental policies, high accuracy of these estimates is required. One of the directions in the scientific discussion on biases in stated preference (SP) valuation surveys builds on dual-process theories of judgment. The paper contributes to this literature by presenting an experiment where two types of judgment ...
    • Methane bubbles in the Arctic Ocean. Quantification, variability analysis and modelling of free and dissolved methane from the seafloor to the atmosphere 

      Jansson, Pär (Doctoral thesis; Doktorgradsavhandling, 2018-11-09)
      Intensive but heterogeneous and transient seepage of methane (CH4) bubbles from the seafloor exist west of Prins Karls Forland (PKF), offshore western Svalbard. The powerful greenhouse gas CH4, has 32 times higher warming potential than carbon dioxide (CO2) and if seepage of CH4 from the seafloor reaches the atmosphere, it will contribute to the warming climate. Warming of the oceans may in turn, ...
    • Opportunity Cost of Environmental Conservation in the Presence of Externalities: Application to the Farmed and Wild Salmon Trade-Off in Norway 

      Nikitina, Ekaterina (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-08-17)
      Estimation of the opportunity cost is necessary for the economic assessment of environmental conservation policies. This paper considers the case where an environmental good is negatively affected in the process of the production of marketable goods. In the presence of externalities, conservation implies the undertaking of abatement measures by polluters. A relevant measure of opportunity cost in ...
    • Holocene floristic diversity and richness in northeast Norway revealed by sedimentary ancient DNA (sedaDNA) and pollen 

      Clarke, Charlotte; Edwards, Mary Elizabeth; Brown, Antony Gavin; Gielly, Ludovic; Lammers, Youri; Heintzman, Peter D.; Murguzur, Francisco Javier Ancin; Bråthen, Kari Anne; Goslar, Tomasz; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-30)
      We present a Holocene record of floristic diversity and environmental change for the central Varanger Peninsula, Finnmark, based on ancient DNA extracted from the sediments of a small lake (<i>sed</i>aDNA). The record covers the period c. 10 700 to 3300 cal. a BP and is complemented by pollen data. Measures of species richness, sample evenness and beta diversity were calculated based on <i>sed</i>aDNA ...

      Tephnadze, G; Persson, Lars Erik (Journal article; Peer reviewed, 2018-12-19)
      In this paper, we state and prove some new inequalities related to the rate of Lp approximation by Cesàro means of the quadratic partial sums of double Vilenkin–Fourier series of functions from Lp.
    • Insight into the fluorescence quenching of Trp214 at HSA by the Dimetridazole ligand from simulation 

      Pomogaev, Valdimir A; Ramazanov, Ruslan R; Ruud, Kenneth; Artyukhov, Victor Ya (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-24)
      Spectroscopy is an important tool for detecting drug binding to amino acid sequences. One such important spectroscopic process is the fluorescence quenching due to charge transfer (CT) processes between a drug molecule and the chromophore center of Human Serum Albumin (HSA). We present a theoretical investigation of the CT occurring upon electronic excitation when a dimetridazole (Dmz) molecule ...
    • Design and development of a context-aware knowledge-based module for identifying relevant information and information gaps in patients with type 1 diabetes self-collected health data 

      Giordanengo, Alain; Øzturk, Pinar; Hansen, Anne Helen; Årsand, Eirik; Grøttland, Astrid; Hartvigsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-11)
      <p><i>Background</i>: Patients with diabetes use an increasing number of self-management tools in their daily life. However, health institutions rarely use the data generated by these services mainly due to (1) the lack of data reliability, and (2) medical workers spending too much time extracting relevant information from the vast amount of data produced. This work is part of the FullFlow project, ...
    • Exceptionally simple PDE 

      The, Dennis (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-08)
      We give local descriptions of parabolic contact structures and show how their flat models yield explicit PDE having symmetry algebras isomorphic to all complex simple Lie algebras except <math><msub is="true"><mrow is="true"><mi mathvariant="fraktur" is="true">sl</mi></mrow><mrow is="true"><mn is="true">2</mn></mrow></msub></math>. This yields a remarkably uniform generalization of the Cartan–Engel ...
    • Effects of acute exposure to dispersed oil and burned oil residue on long-term survival, growth, and reproductive development in polar cod (Boreogadus saida) 

      Bender, Morgan Lizabeth; Frantzen, marianne; Camus, Lionel; Le Floch, Sebastien; Palerud, Jocelyn Hernandez; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-05)
      The present study investigates the potential long-term physiological effects on maturing polar cod (<i>Boreogadus saida</i>), an Arctic key species, after an acute exposure (48 h) to environmentally realistic concentrations of either mechanically dispersed oil (MDO), chemically dispersed oil (CDO) or burned oil residues (BO) (N = 58–60 per treatment). Following exposure, fish were monitored in a ...
    • Spreading of drill cuttings and sediment recovery of three exploration wells of different ages, SW Barents Sea, Norway 

      Junttila, Juho; Dijkstra, Noortje; Sørensen, Steffen Aagaard (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-14)
      Five stations (≤250 m from the well heads) from three exploration wells of different ages from the SW Barents Sea were studied to investigate the spreading of drill cuttings and sediment quality. Two of the wells were drilled before the restriction of use of oil-based drilling fluids (1993). Elevated concentrations of Ba were found in sediments near all the wells with the highest concentrations ...
    • Effects of dietary crude oil exposure on molecular and physiological parameters related to lipid homeostasis in polar cod (Boreogadus saida) 

      Vieweg, Ireen; Bilbao, Eider; Meador, James P.; Cancio, Ibon; Bender, Morgan Lizabeth; Cajaraville, Miren P.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-17)
      Polar cod is an abundant Arctic key species, inhabiting an ecosystem that is subjected to rapid climate change and increased petroleum related activities. Few studies have investigated biological effects of crude oil on lipid metabolism in this species, despite lipids being a crucial compound for Arctic species to adapt to the high seasonality in food abundance in their habitat. This study examines ...
    • Minimizing polymerase biases in metabarcoding 

      Nichols, Ruth V.; Vollmers, Christopher; Newsom, Lee A.; Wang, Yue; Heintzman, Peter D.; Leighton, McKenna; Green, Richard E.; Shapiro, Beth (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
      DNA metabarcoding is an increasingly popular method to characterize and quantify biodiversity in environmental samples. Metabarcoding approaches simultaneously amplify a short, variable genomic region, or “barcode,” from a broad taxonomic group via the polymerase chain reaction (PCR), using universal primers that anneal to flanking conserved regions. Results of these experiments are reported as ...
    • The demands they are a-changin' 

      Brækkan, Eivind Hestvik; Thyholdt, Sverre Braathen; Asche, Frank; Myrland, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-15)
      Smooth operators such as time trends are often applied to deal with unidentified demand shifters. However, if unknown factors affect demand irregularly, a time trend fails to capture the variation. We present an index approach for estimating irregular demand shifts, decomposing total demand shifts into predicted and unexplained effects. This allows separating demand shifts caused by known factors ...
    • Iron‐Catalyzed Carbenoid Transfer Reactions of Vinyl Sulfoxonium Ylides: An Experimental and Computational Study 

      Vaitla, Janakiram; Bayer, Annette; Hopmann, Kathrin Helen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-15)
      A method for the generation of unprecedented vinyl carbenoids from sulfoxonium ylides has been developed and applied in the synthesis of a diverse array of heterocycles such as indolizines, pyrroles, 3‐pyrrolin‐2‐ones, and furans. The reactions proceed by FeBr<sub>2</sub> catalysis under mild reaction conditions with a broad substrate scope. A reaction pathway involving iron carbenoids is proposed ...
    • 'No fornicar': el discurso de culpa, penitencia y perdón en el Confessonario en lengua cumanagota (1723) de Diego de Tapia 

      Sarion, Roxana (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      Este artículo plantea el análisis del Confessonario en lengua cumanagota (1723) del franciscano Diego de Tapia como herramienta de conversión basada en modelos de represión y técnicas inquisitoriales. Con el fin de perseguir al indígena en su conducta infiel y lasciva, el confesionario se presenta como instrumento coercitivo destinado a enseñar la ética cristiana a los indígenas de la costa oriental ...
