The impact of audit oversight in Norway: International collaboration and audit quality
(Doctoral thesis; Doktorgradsavhandling, 2017-09-22)
The purpose of this thesis is to explore the nature of the audit oversight system and examples of national and international collaboration by means of a joint inspection process between the Public Company Accounting Oversight Board (PCAOB) of the United States and the Financial Supervisory Authority of Norway (FSA). In addition, the thesis will analyze literature regarding how auditors detect fraud ...
Topics on market microstructure and asset pricing using intraday data from the Oslo stock market.
(Doctoral thesis; Doktorgradsavhandling, 2017-08-23)
What drives asset prices in the financial market? How can we predict these prices? Finding
the relationship between different factors or between different variables could help to answer
these questions. First, links between asset pricing models and other market microstructure
variables can be used to investigate sources to explain asset prices. Second, rapid changes in the
microstructure ...
Indulging in Premium versus Luxury products: Seeking justification to avoid regrets
(Doctoral thesis; Doktorgradsavhandling, 2018-05-22)
The demand for premium products is expanding across saturated markets, such as food and beverages. Premium products stand out on the store shelf because they signal higher quality and exclusivity with their fine product packaging, higher prices, and selective distribution. Despite the growing consumer demand for these products, and acknowledgments in the literature that the lines between luxury and ...
Feeding and fasting in Arctic charr (Salvelinus alpinus (Linnaeus, 1758)): Central regulation of food intake in a highly seasonal fish species
(Doctoral thesis; Doktorgradsavhandling, 2018-05-22)
Central control mechanisms of food intake vary between different fish species. Few studies
have investigated the role of central appetite regulators in fish species that show natural
seasonal variations in food intake. Yet, seasonal fishes are particularly interesting because
their potential seasonally sliding set-points in appetite and energy homeostasis may reveal
new information about the ...
Mass cultivation of some common coldwater diatoms (Bacillariophyceae): lipids vs. growth conditions
(Doctoral thesis; Doktorgradsavhandling, 2017-02-27)
The present study was aimed at investigating northern diatoms as sustainable sources of omega-3 fatty acids widely used and now much needed in salmon aquaculture as well as ingredients to be used in nutraceuticals in the human diet.
As known, fish oil is currently the main source of physiologically requisite fatty acids such as eicosapentaenoic (EPA) and docosahexaenoic acids (DHA). Due to the rapid ...
Fiskeren som forsvant? En studie av avfolking, overbefolking og endringsprosesser i norsk fiskerinæring
(Doctoral thesis; Doktorgradsavhandling, 2003-02-28)
Hva er en fisker? Dette er det sentrale spørsmålet i denne avhandlinga. Spørsmålet er
utgangspunkt for å utforske endringsprosesser i fiskerinæringa, både i fortida og i samtida. På
bakgrunn av dette drøfter avhandlinga hvilke oppfatninger, forståelser og beskrivelser som til
enhver tid benyttes til å definere hva fiskere er i ulike sammenhenger. Undersøkelsen starter i
det som kan kalles ...
Post mortem proteolytic degradation of myosin heavy chain in skeletal muscle of Atlantic cod
(Doctoral thesis; Doktorgradsavhandling, 2011-01-28)
One of the most important parameters of quality regarding meat both from mammals and fish is texture. The post mortem degradation of muscle and connective tissue proteins during tenderization of meat from warm-blooded animals is unwanted in fish due to a loss of product quality. Soft fillet and gaping are common problems both in wild and farmed cod and have huge impact on the quality and the consumers’ ...
Scavenging amphipods in the high Arctic : Studies of benthic and sympagic amphipods in the genera Onisimus and Anonyx
(Doctoral thesis; Doktorgradsavhandling, 2011-05-02)
The main objective of this study was to increase our knowledge about the ecology of scavenging amphipods, particularly amphipods within the genera Onisimus and Anonyx. Specifically, the emphasis was to increase the knowledge of ice-associated (sympagic) Onisimus-species, but as these species are rather inaccessible, an approach using benthic congeners as proxies was chosen. By studying the shallow-water ...
Key genes and regulators associated with sexual differentiation and gonad development in Atlantic cod (Gadus morhua L.)
(Doctoral thesis; Doktorgradsavhandling, 2012-02-17)
Atlantic cod (Gadus morhua L.) is a promising cold-water aquaculture species, but early sexual maturation is a major problem in today’s cod farming. Teleosts display a wide variety of sex determination and sex differentiation mechanisms, ranging from genetic to environmental factors and the sexual plasticity in gonads and brain possibly reflects on a combination of these. From a practical point of ...
Management of the alien invasive red king crab Integrating natural and social science perspectives
(Doctoral thesis; Doktorgradsavhandling, 2012-06-12)
The red king crab (Paralithodes camtschaticus) is a highly valuable resource that also represents a potential threat since it is an alien invasive species in the Barents Sea ecosystem. This thesis explores the use of different interdisciplinary frameworks to analyse how ecological, social and economic concerns could be accounted for in deciding on how the king crab should be managed in the Norwegian ...
