This thesis explores various aspects of the application of economic analysis to Atlantic salmon management in Norway. The purpose and contributions are twofold. On the one hand, the thesis seeks to improve economic toolbox used to analyse environmental-economic trade-offs. On the other hand, it yields specific conclusions and recommendations for the case of Atlantic salmon management in Norway and ...

We examine whether behavioural sunk costs are related to an increased willingness to make risky decisions. Rational agents’ decisions should not be contingent on sunk costs; however, foregoing research suggests that individuals in fact do react to such costs. Few studies have examined behavioural sunk costs and risk-taking with “real stakes”, which is an important topic of research as many ...

Regulatory focus theory er en teori som omhandler hvordan vi mennesker motiveres ulikt som følge av at noen av oss er avvergingsfokuserte og andre er avansefokuserte. Avvergingsfokuserte mennesker motiveres til handle slik de må for å unngå en uønsket endesituasjon. Avansefokuserte mennesker er motivert til å handle for å nå en ønsket endesituasjon. Tidligere har det blitt observert at om man ...

In addition to indirect support to fisheries, marine habitats also provide non-use benefits often overlooked in most bioeconomic models. We expand a dynamic bioeconomic fisheries model where presence of natural habitats reduces fishing cost via aggregation effects and provides non-use benefits. The theoretical model is illustrated with an application to cold-water corals in Norway where two fishing ...

<i>Allocetraria madreporiformis</i> is a small, finger-like, fruticose lichen with isolated occurrences in the inner fiord section of the long, straight fiord Wijdefjorden in Svalbard. Several new localities are added and mapped here, and we show that the species is confined to exclusive high-arctic steppe habitats on finetextured, moderately alkaline soil, exposed to wind erosion and aeolian transport ...

Recent genomic analyses have provided substantial evidence for past periods of gene flow from polar bears (<i>Ursus maritimus</i>) into Alaskan brown bears (<i>Ursus arctos</i>), with some analyses suggesting a link between climate change and genomic introgression. However, because it has mainly been possible to sample bears from the present day, the timing, frequency, and evolutionary significance ...

<i>Background</i> - The NOR-SWITCH main and extension trials demonstrated that switching from originator to biosimilar infliximab (CT-P13) is efficacious and safe across six diseases. However, a subgroup analysis of Crohn’s disease (CD) in the main trial displayed a close to significant difference favouring originator infliximab, and more scientific data have therefore been requested.<p><p> <i> ...

While designing the power requirements of a ship, the most important factor to be considered is the ship resistance, or the sea drag forces acting on the ship. It is important to have an estimate of the ship resistance while designing the propulsion system since the power required to overcome the sea drag forces contribute to ‘losses’ in the propulsion system. There are three main methods to calculate ...

A new rare Upper Ordovician mound dwelling palaeoloricate chiton is described as <i>Crassaplax collicola</i> gen. et sp. nov. from three large isolated intermediate valves from the Katian carbonate mud mounds of the Boda Limestone in the Siljan district of central Sweden. Together with the previously known <i>Spicuchelodes</i>? sp., also from the Boda Limestone, these are the only known Late Ordovician ...

In preparation for a legal implementation of EU-regulation 1829/2003, the Norwegian Environment Agency has requested the Norwegian Food Safety Authority to give final opinions on all genetically modified organisms (GMOs) and products containing or consisting of GMOs that are authorized in the European Union under Directive 2001/18/EC or Regulation 1829/2003/EC within ...
