The arctic tundra is most sensitive to climate change. The change can be quantified from observations of the fauna, flora and weather conditions. To do observations at sufficient spatial and temporal resolution, ground-based observation nodes with sensors are needed. However, the arctic tundra is resource-limited with regards to energy, data networks, and humans. There are also regulatory and practical ...

Formålet med denne studien har vært å belyse digital ledelse gjennom erfaringene til digitale ledere og medarbeidere i virtuelle team. For å operasjonalisere vår problemstilling: Hvordan utøves og oppfattes digital ledelse når det gjelder lederstiler, kommunikasjon og tillit? har vi benyttet egne forskningsspørsmål om lederstiler, kommunikasjon og tillit. Studien har blitt gjennomført ...

The goal of this thesis was to explore, collect and highlight various strategies that British, German and Norwegian documentaries and museum exhibitions use to mediate different cultural memories about the same historical event. By examining the story of the German battleship Tirpitz that was sunk by the British in Norway during World War II, this thesis analyses the production of memory potentials ...

The purpose of this dissertation, <i>Hybrid heroines in the literary Arctic</i>, is to bring literary studies to the popular literary Arctic through analyzes of Arctic indigenous cultures and lifeworlds. These lifeworlds have to varying degrees been subject to colonial processes, and both social, historical and natural conditions in addition to gender and ethnicity affect the hybrid protagonists' ...

The last few decades have seen an increasing use of merit-based immigration systems, whereby migrants are treated differently on the basis of their skills, education, and wealth. In this thesis I argue that there are justice-based reasons to be sceptical of such policies. While I agree that there are good grounds for states to control their own borders, related to self-determination and the welfare ...

Ecologists are still puzzled by the diverse population dynamics of herbivorous small mammals that range from high-amplitude, multiannual cycles to stable dynamics. Theory predicts that this diversity results from combinations of climatic seasonality, weather stochasticity, and density-dependent food web interactions. The almost ubiquitous 3- to 5-y cycles in boreal and arctic climates may theoretically ...

Bacterial genomes typically consist of one large chromosome, but can also include secondary replicons. These so-called multipartite genomes are scattered on the bacterial tree of life with the majority of cases belonging to Proteobacteria. Within the class gamma-proteobacteria, multipartite genomes are restricted to the two families <i>Vibrionaceae</i> and <i>Pseudoalteromonadaceae</i>. Whereas the ...

<p>Parasites negatively affect hosts and may constitute serious management problems. At the same time, parasites are integral components of ecosystems and represent a substantial part of the biodiversity on earth. Understanding the ecological factors that influence the abundance and distribution of parasite populations is therefore important from a management perspective, but also to understand the ...

Inquiry-based methods have been seen as important for developing science in school. There are good reasons why the work of designing various technological devices in technology should also be part of inquiry-based methods. If so, it requires that the teachers have an exploratory approach in communicat-ing with students. In this paper, we analyze the communication between teachers and students in six ...

From previous work, it was identified two analytes of interest, produced by Lacinutrix sp. The two analytes are iso-branched lyso-ornithine lipids with only one CH2 group differing between the two compounds, in the hydrocarbon chain (lysoC15:0 and C16:0). The bacterium was isolated from the marine sponge Halicondria sp. that was collected beside Bjørnøya, on a research cruise in 2009. The analytes ...
