Digital outcrop models (DOMs) acquired from consumer drones, processed using user-friendly photogrammetric software and shared with the wider audience through online platforms are a cornerstone of this digital geological revolution. Integration of DOMs with other geoscientific data, such ...
    • Assessing the impact of the securitization narrative on climate change adaptation in Nigeria 

      Oramah, Chinwe P; Olsen, Odd Einar Falnes; Gould, Kenneth Arne Pettersen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-01)
      In Nigeria, the threat posed by climate change is leading policymakers and the media to frame climate change as a security threat that warrants support for adaptive actions. We draw upon securitization theory to examine how security narratives affect climate change adaptation. Using primary and secondary data, we find that although securitization arguments are easily identified in climate change ...
    • Atmospheric Contamination of Coastal Cities by the Exhaust Emissions of Docked Marine Vessels: The Case of Tromsø 

      Zubiaga, Asier; Madsen, Synne; Khawaja, Hassan; Boiger, Gernot (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-03)
      Docked ships are a source of contamination for the city while they keep their engine working. Plume emissions from large boats can carry a number of pollutants to nearby cities causing a detrimental effect on the life quality and health of local citizens and ecosystems. A computational fluid dynamics model of the harbour area of Tromsø has been built in order to model the deposition of CO2 gas emitted ...

      Birkelund, Johan; Cherry, Todd (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-10)
      This paper reports on an experiment that investigates how inequality in advantage affects individual preferences for honesty and generosity. In a two-stage experiment, subjects first earn money according to self-reported production, which can include honest and dishonest reports. Subjects then play the dictator game and decide how much, if any, of their earnings to share with an anonymous recipient. ...
    • The hers and his of prosociality across 10 countries 

      Olsson, Maria; Froehlich, Laura; Dorrough, Angela R.; Martiny, Sarah E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-19)
      Is there a ‘more helpful’ gender? The present research assessed gender differences in prosocial self-perceptions, prosocial behavioural intentions, and prosocial (transfer) behaviour in same- and other-gender interactions in 10 countries (N = 1,915). The present results showed negligible differences in the degree to which women and men saw themselves as prosocial. However, larger gender differences ...

      <p>Background: Mothers with diabetes are less likely to achieve successful breastfeeding. Antenatal breastmilk expression (ABE) may facilitate earlier breastfeeding, but feasibility of introducing ABE and its acceptance among Scandinavian women have previously not been investigated. <p>Methods: This observational trial was conducted between the 1 January 2019 and the 12 March 2020 in Tromsø, Norway. ...
    • Scraping the bottom of the barrel? Evidence on social mobility and internal migration from rural areas in nineteenth-century Norway 

      Moilanen, Mikko; Myhr, Sindre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-11)
      We aim to answer whether expected occupational gains motivated rural-urban and rural-rural migration in nineteenth-century Norway. Human capital theory indicates that the higher expected gains, the more prone an individual will be to migrate. We use a micro-level data set of over 42,000 rural sons linked to their fathers based on 1865 and 1900 Norwegian censuses and employ a switching endogenous ...
    • Existence and Uniqueness of Some Cauchy Type Problems in Fractional q-Difference Calculus 

      Shaimardan, S.; Persson, Lars Erik; Tokmagambetov, N.S. (Journal article; Tidsskriftartikkel, 2020)
      In this paper we derive a sufficient condition for the existence of a unique solution of a Cauchy type q-fractional problem (involving the fractional q-derivative of Riemann-Liouville type) for some nonlinear differential equations. The key technique is to first prove that this Cauchy type q-fractional problem is equivalent to a corresponding Volterra q-integral equation. Moreover, we define the ...
    • The professional project of graphic designers and universities' visual identities 

      Moldenæs, Turid; Pettersen, Hilde Marie (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-19)
      Contrary to earlier research on why universities change their visual identities from traditional to more abstract ones, resting on a demand-side approach, we offer an explanation based on a supply-side approach. We argue that universities’ change of visual identities toward abstract symbols reflects a professional logic shared by graphic designers and discuss the mechanisms and institutional agents ...
    • Throwing Pebbles While Waiting: An Autoethnographic Exploration of Mental Health and Colonialism 

      Kelly, Limes Taylor; Sørly, Rita; Karlsson, Bengt Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-23)
      In this article, three scholars jointly investigate questions of Western colonization and mental health. While their areas of interest and experience vary, the authors discuss oppression as a common thread connecting their ideas about mental health and its medicalization. In line with Toyosaki et al. (2009), the researchers did a community autoethnography, performing written dialogue as a dynamic ...
