Denne oppgaven tar for seg markedseffisiens på Oslo Børs. Den overordnede problemstillingen er: I hvilken grad er aksjemarkedet på Oslo Børs effisient? Dette er et omfattende spørsmål og vi vil undersøke spørsmålet i lys av børsmeldinger om flagging og meldepliktige handler. Vårt første forskningsspørsmål er: Avviker kursutviklingen i aksjer fra markedets utvikling i tiden etter publisering av ...

Studien har som formål å undersøke hvilke lønnsomhetsdrivere som påvirker norske torsketrålere. Fartøygruppen torsketrål er fartøygruppen som oppnår høyest lønnsomhet i fiskeflåten i Norge. Vi skal undersøke om det er forskjeller i oppnådd lønnsomhet mellom de ulike fartøyene. Studien tar for seg variablene: alder på fartøy og eierskap. Vi undersøker om variablene er lønnsomhetsdriverne for oppnådd ...

Det har blitt svært vanlig å dele opp de kommunale oppgaveløsningene i egne selskaper, og siden 1990-tallet har det vært en stor økning i antallet kommunalt eide aksjeselskaper. Kommunale aksjeselskaper er egne rettssubjekter, og kommunene får et svært begrenset ansvar overfor disse. De er for eksempel ikke forpliktet til å betale mer enn aksjeinnskuddet, og har ingen forpliktelser for selskapets ...

To respond to the call for broader ways to understand academic engagement in sustainable tourism, I conceptualized a relational practice-based approach, termed cross-community enactive research. Relying on central ideas from the enactive research approach by entrepreneurship scholar Bengt Johannisson, which draws on autoethnography and action research, and the communities of practice theory by ...

River ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater ...

Nicotinic acetylcholine receptors (nAChRs) play an important role in the functioning of the central and peripheral nervous systems, and other organs of living creatures. There are several subtypes of nAChRs, and almost all of them are considered as pharmacological targets in different pathological states. The crude venom of the sea anemone Metridium senile showed the ability to interact with ...

This study asks how small tourism providers use stories to make sense of their world in terms of sustainability. It elaborates on sense-making and story concepts and their relevance to sustainability; adopts an enactive research approach and multiple methods (participation, journaling, interviews, document analysis, content analysis); and explores five providers’ stories about themselves, the ...

Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- precision monitoring under variable ambient conditions. We investigated the use of handheld sensor NDVI for monitoring pale lichen cover across three study sites from boreal heathlands ...

The Norwegian Atlantic salmon farming industry is halted by challenges related to environmental impact and fish welfare. Some of the issues have been suggested solved by the use of novel genome editing technologies, such as CRISPR, which allows for targeted mutations and speeding up fish breeding. For successful introduction, applications of the technology need to be socially acceptable and contribute ...

Abandoned, lost, and discarded fishing gear (ALDFG) is claimed to be a global problem with impacts on marine animals and ecosystems, posing considerable ecological and socioeconomic challenges. Nonetheless, insufficient understanding regarding how marine ecosystem services are affected by ALDFG creates a knowledge gap that challenges a holistic estimation of the long-term economic impacts of using ...
