Bankers kredittgivningsprosess i praksis : En studie om hvordan bankers målemodeller blir påvirket av nøkkeltall, regnskapsprinsipp, regnskapsmanipul…
2020
Master's thesis in Accounting and auditing (BE508) Denne studien undersøker hvordan bankers kredittgivningsprosess utføres i praksis i forhold til hvordan banker bruker nøkkeltall, hvordan regnskapsmanipulering vurderes, hvordan bærekraft blir vurdert og hvordan bankene håndterer forskjellige regnskapsprinsipper.Problemstillingen vår er følgende: Hvordan bruker banker sine kredittscoremodeller for kredittgivning?Studienhar et eksplorativt design der viønsker å belyse hva banker gjør, og ikke gjør, ved vurdering av nye og eksisterende kunder. Det er blitt gjennomført semistrukturerte intervjuer med kredittsjefer, rådgivere og ledere for bedriftsavdelinger fra banker hvor utvalget er begrense…
Feeding Ecology of Harbour Seals (Phoca vitulina) in Southern Norway
2017
Master's thesis Aquatic Ecology BIO500 - University of Agder 2017 In order to understand ecosystem dynamics and functions it is vital to have knowledge about relationships between predator and prey. Harbour seals (Phoca vitulina) are piscivorous marine mammals found at or near the top of marine food webs. Being mainly piscivores, harbour seals have the potential to come into conflict with fishermen and fisheries. Recently, as the Skagerrak and Kattegat population of harbour seals has increased, claims that seals are depleting the cod population have surfaced. Using scat sampling and otolith identification, harbour seal diet was estimated in four separate locations along the coast of souther…
Assessing the impacts of marine protected areas on wrasse populations in Norway

Homing Ability of Goldsinny Wrasse (Ctenolabrus rupestris)
2021
Master's thesis in Coastal ecology (BIO501) After the discovery of delousing abilities of temperate wrasses, several wrasse species are increasingly harvested in Norway and supplied to salmonid aquafarms to combat sea lice infestations. An increased harvesting intensity has raised concerns regarding the sustainability of this comparatively new fishery. Therefore, more research is needed about the targeted wrasses species. Goldsinny wrasses (Ctenolabrus rupestris)are known for having small home ranges and being highly territorial. Minimum size restrictions oblige fishermen to release goldsinnies smaller than 11 cm back to the sea, but this is often done far from the capture site. It is very …
Visual fish assemblage inventory of outer Oslo fjord, with special emphasis on young-of-the-year Atlantic cod (Gadus morhua)
2021
Master's thesis in Coastal ecology (BIO501) The coastal zone along the outer Oslofjord is physically unique and home to many ecologically depleted and economically important species, including Atlantic cod (Gadus morhua). Coastal cod in Skagerrak is divided into two ecotypes that co-exist in outer Oslofjord. Remnant local populations are considered sensitive to climate disturbances and anthropogenic influences. Recruitment of cod in Skagerrak is monitored in the annual beach seine sampling. A strong year-class of cod recruited to nursery areas in outer Oslo fjord in 2017. Although recruitment of cod has been monitored extensively in Skagerrak, studies have only recently begun to examine the…
Long term effects of activated carbon on benthic communities
2021
Master's thesis in Coastal ecology (BIO501) Thin-layer capping with activated carbon (AC) has a potential as situ remediation method for sediments exposed to hydrophobic organic compounds (HOCs). This treatment was applied at two test fields; one in the Eidangerfjord (95 m) and the other in the Ormerfjord (30 m) in 2009. These two fjords are a part of the Grenland fjord system which have a long history of contaminated sediments. In this study we will address long-term effects of thin-layer capping with AC on the benthic community nine years later. Number of individuals, species and biomass was significantly reduced in both test fields compared to their corresponding reference fields. The di…
Methods for studying coastal bivalves in a changing world : A review and implications for management
2021
Master's thesis in Coastal ecology (BIO501) Anthropogenic activities such as pollution, CO2 emission, and overfishing, are among leading reasons for global environmental change and negative impacts on the marine environment including loss of biodiversity. Marine bivalves are an example of species that suffers from such consequences while they have high value in both aquaculture and marine ecosystems. With the existence of many threats including overharvesting, invasive species, parasites, and diseases, coastal bivalves such as flat oysters (Ostrea edulis) and blue mussels (Mytilus spp) are in many places endangered. The existing knowledge gaps in the historic and current distribution, howev…
Do cold-water corals spatially correlate with submarine canyons in the Bay of Biscay? : A GIS study analysing the spatial distribution of cold-water …
2020
Master's thesis in Coastal ecology (BIO501) The seascape of the Bay of Biscay is a mysterious place. It is located to the west of France and the north of Spainand is often defined as well-differentiated geomorphological unit. The continental margin of the BoB is incised with many submarine canyons and is also thought to be a hotspot for cold-water corals.Unfortunately, it is an area under high anthropogenic pressure where intense fishing activity, bottom trawling especially, is causing major disturbances to benthic habitats such as cold-water corals. Cold-water corals have been well studied along the European margin and have more frequently been recorded in the northeastAtlantic than any ot…
Tick-borne pathogens in Ixodes ricinus ticks collected from migratory birds in southern Norway
2020
Birds are important hosts for the first life stages of the Ixodes ricinus tick and they can transport their parasites over long distances. The aim of this study was to investigate the prevalence of Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum, Neoehrlichia mikurensis and Rickettsia helvetica in ticks collected from migratory birds in Norway. A total of 815 Ixodes ricinus ticks from 216 birds trapped at Lista Bird Observatory in southern Norway during spring and autumn migration in 2008 were analysed by real-time PCR. B. burgdorferi s. l. was the most prevalent pathogen, detected in 6.1% of the ticks. The prevalence of N. mikurensis, A. phagocytophilum and R. helvetica was 1.2%…

2007
Regionalt Fosterhjemsarbeid avd. Kristiansand, Barne-, ungdoms- og familieetaten i region Sør arrangerte et kurs til foreldre med barn i fosterhjem vinteren 2006. Studien Det vanskelige foreldreskapet er blitt til ved at Regionalt fosterhjemsarbeid i Bufetat, avd. Kristiansand henvendte seg til PRAXIS – Sør/ Høgskolen i Agder v/ Institutt for sosiologi, sosialt arbeid og velferdsfag og ba om bistand til en oppsummering av foreldrenes opplevelse av egensituasjon og hvordan de har opplevd å delta på kurset. Studiens problemstillinger er, Hvordan presenterer foreldre som har deltatt på kurs til foreldre med barn i fosterhjem sin situasjon? Hvordan presenterer foreldre med barn i fosterhjem sit…
