    • “There's an art to it” - Exploring Sami Health Culture and Empowering Communication through an E-health Application 

      Aho, Karianne (Mastergradsoppgave; Master thesis, 2024-05-15)
      Studies have shown that the Sami culture of communicating about health can often be indirect and reliant on implications and hints rather than clear unambiguous statements. The style is described as “roundabout”, circling around a topic before closing in on it. Modern medicine typically values directness and unambiguousness in its mission of effective anamnesis and diagnosis. Due to these differing ...

      Nedelchev, Emiliyan (Master thesis; Mastergradsoppgave, 2024-05-16)
      Our planet has experienced at least five major mass extinction events, which have occasionally brought the flora and fauna to almost complete collapse , yet they have been pivotal in the evolution of life as we know it. This thesis explores potential causes of mass extinctions, focusing particularly on the Late Devonian mass extinction event, which is the least understood of the major five. Over the ...
    • Modelling the Earth System - From Tipping Elements to Reconstructions 

      Bochow, Nils (Doctoral thesis; Doktorgradsavhandling, 2024-06-17)
      Climate change can trigger climate tipping points, which are among the major threats to human society. Tipping points are thresholds beyond which a system undergoes abrupt, often irreversible, changes even if the external forcing is brought to a halt. Several large-scale elements in the Earth system are considered tipping elements with global consequences once critical thresholds are crossed and ...
