Abstract: The overall aim of the thesis was to study immunological effects of pollutants in Barents Sea. The Glaucous gull (Larus hyperboreus), black-legged kittiwake (Rissa tridactyla) and Atlantic puffin (Fratercula arctica) were studied. The apex predatory glaucous gull have high levels of persistent organic pollutants (POPs), while the fish eating black-legged kittiwake and Atlantic puffin are located lower in the food-chain and have lower levels of POPs. In breeding glaucous gulls, positive correlations between levels of intestinal nematode and organochlorine (OC) levels were observed. The intestinal parasite intensities could be seen as an end result of the immune system’s battle against the establishment and survival of the parasites. An increased infection with increased OC levels might be explained by immune suppression activity of OCs. The influence of the Barents Sea’s POP-cocktails on the developing immune system was studied on laboratory-raised glaucous gull chicks. The polluted group that simulated “naturally” polluted glaucous gull chicks responded less well to an influenza vaccine and had lower levels of circulating immunoglobulin-G (IgG) and IgM than the control group. The hypothesis of a POP-induced immune suppression was also investigated in the less polluted black-legged kittiwake and Atlantic puffin. The predictions of an altered level of circulating IgG with OCP, PCB or PBDE levels were tested. The results show no indication of correlations between the IgG and pollutant levels. Naturally dead glaucous gulls were studied in an attempt to evaluate whether pollutants contribute to the death. Autopsies and POP analyses reveal that the brain levels of pesticides and PCBs were the same as in a sample of dead glaucous gulls from 1989, while the liver levels were significantly lower. The brain levels thereby strengthen the theory that an additional stress provided from elevated pollutant levels could be deadly.

Abstract: Fra milleniumsskiftet og frem til i dag har forskningen på bedriftsstyret fjernet seg fra, og i følge noen avansert forbi det å forske på direkte sammenhenger mellom styrets sammenhenger og selskapets økonomiske resultater. Denne studien er i denne sammenhengen ment å være en review av kunnskap allerede utviklet i et utvalg av de aller mest innflytelsesrike vitenskapelige arbeider om emnet. Disse arbeidene blir studert i lys av tre organisasjonsteoretiske perspektiver, det instrumentelle, det gammelinstitusjonelle og det nyinstitusjonelle perspektivet. Studien sammenligner videre ”Norsk anbefaling for eierstyring og selskapsledelse” med de sentrale funn som gjøres i gjennomgangen av forskningslitteraturen. Studien viser at ”Norsk anbefaling for eierstyring og selskapsledelse” i varierende grad finner støtte i eksisterende forskning. URI: http://hdl.handle.net/10037/1543 File(s) in this item: 1

Abstract: The aim of this paper is to look more closely at the processes involving the adoption of internet in a Nepali mountain village. Two and a half months of fieldwork was performed at a primary school and a cybercafe in Namche Bazaar, Solukhumbu district, Nepal. My aim is to be informative about the processes revolving around the internet in a general global sense. Therefore my thesis is more concerned with the internet than the particular cultural setting of Nepal or Namche. I will be concentrating on the sociotechnical system consisting of the internet, computers and people (both Nepali and tourists). Point one: my approach is informed by the distinction between modern and traditional, which in simplified terms is the degree of reliance on context. For characterisation I am using Edward Hall's categories of high-context and low-context. Point two: my approach is also informed by the critique of point one, of the idea of low-context communication, of context-independence, of abstract modernity. For this I rely on the actor-network theory. Internet used to be seen as a monolithic placeless cyberspace which would make us all similar to each other. My main finding is that this is not always the case. It is a collection of different people doing different things while embedded in their social contexts.

Abstract: This study examines the contribution of the 3-D model in an early development set-up for pectin tablets. Therefore, the aim of this work is to extract as much information on the compression behaviour from as few tablets as possible. Pectins with various degrees of methoxylation (DM) were studied (4-72%). The compressibility was evaluated by classical “in-die” Heckel and Kawakita analyses in addition to the 3-D modelling. For validation purposes well-known reference materials were included. 3-D modelling applied on data of single tablets yielded a certain degree of information on the compressibility. When several tablets with different maximum relative densities were included, no additional information was gained in the classical evaluation, whereas the 3D-model provided additional information through the shape of the 3-D parameter plot: pectins with a DM ? 25% consolidated predominantly by elastic deformation similarly to the 3-D parameter plot of pregelatinized starch (PGS). The 3-D analysis also suggests some degree of fragmentation, and for some of the low-methoxylated pectins (DM ? 10%) viscoelastic deformation. This study showed that by application of 3-D modelling it is possible to differentiate elastic and viscoelastic materials, if tablets of different maximum relative densities are evaluated.

Abstract: Pektinpulver med ulike prosentar metoksylering vart komprimert i ein komprimeringssimulator. Dette er ei avansert tablettmaskin som svært nøyaktig måler distansen tablettstempelet har gått (på mikrometernivå) og kor stor kraft som er involvert under komprimeringa (samantrykkinga av pulveret). Pektin med metoksyleringsgrad under 10% (også kalla pektinsyrer) gav dei mekanisk sterkaste tablettane, og er såleis den pektintypen det bør fokuserast på i framtidige forsøk med pektin som eit tabletthjelpestoff. Høgmetoksylert pektin, dvs. meir enn 50% metoksylering, var ueigna i tablttering ettersom dei ikkje gav samanhengande tablettar. Hovudsakleg skjedde det ein elastisk deformasjon med pektinpartiklane, og sidan dette generelt er ugunstig med hensyn på binding og mekanisk sterke tablettar vart det undersøkt kva mekanismar som bidreg til at tablettane heng saman. Det vart funne at ei viss grad av fragmentering skjedde i pektinsyrene. Plastisk deformasjon var det lite av. Avhandlinga viser at pektinsyrene og til dels andre pektintypar med metoksylering mindre enn eller lik 40% er veleigna som eit tabletthjelpestoff som kan fungere som ein bærar av ein aktiv substans til tjukktarmen.

Abstract: Depending on the particular institutional and organizational set-up, different management tasks can be suitable for different forms of co-management arrangement. This thesis focuses on examining the possibility of implementing the marketing-oriented fisheries co-management in Lake Victoria (Tanzanian side) for Nile perch fisheries. The community-based organization BMU was selected as fisher’s representative organization in order to investigate how it is possible to improve the fisher’s market performance and reduce poverty in that fishing community. The findings of this study indicated that the globalization of Nile perch fishery has attracted number of actors to join the fishery and among of them are middlemen, processing plants and fishers themselves. The current first-hand sales system has greater contribution on poverty situation to the majority fishers and made few players benefits over resource, especially investors of the fish processing plants and the fish agents. The deliberate ignoring to identify and incorporate the problems, needs and opportunities that exist in the fishing communities under the co-management arrangement has made the fishers community less motivated in the participation of resource management activities. Fight for better fish prices and issuing of credits to fishers were the most prioritized first-hand sales activities that proposed by fishers community to be undertaken by the BMU organization. Capacity building for the BMU is highly needed in order for the organization to undertake its responsibilities efficiently and effectively. Theories used in this study include the poverty theory, co-management, SLA and middlemen theory.

Abstract: In the present study the intestinal sac method (ex vivo) was used to evaluate the interactions between lactic acid bacteria and staphylococci in the gastrointestinal (GI) tract of beluga (Huso huso). The distal intestine (DI) of beluga was exposed ex vivo to Staphylococcus aureus, Leuconostoc mesenteroides and Lactobacillus plantarum. Histological changes following bacterial exposure were assessed by light and electron microscopy. Control samples and samples exposed only to L. mesenteroides and a combination of L. mesenteroides and S. aureus, had a similar appearance to intact intestinal mucosal epithelium, with no signs of cellular damage. However, the exposure of the DI to S. aureus and L. plantarum resulted in damaged epithelial cells and disorganised microvilli. Furthermore, 16S rDNA PCR denaturing gradient gel electrophoresis (PCR-DGGE) was used to investigate the adherent microbiota of distal beluga intestine. Several bacterial species were identified by DGGE in the present study that has not previously been identified in beluga. URI: http://hdl.handle.net/10037/4187 File(s) in this item: 1

Abstract: Several studies have found that a high proportion of the population in western countries use complementary and alternative medicine (CAM). However, little is known about whether CAM is offered in hospitals. The aim of this study was to describe to what extent CAM is offered in Norwegian and Danish hospitals and investigate possible changes in Norway since 2001. A one-page questionnaire was sent to all included hospitals in both countries. The questionnaire was sent to the person responsible for the clinical activity, typically the medical director. 99 hospitals in the authority (85%) in Norway and 126 in Denmark (97%) responded. Given contact persons were interviewed. CAM is presently offered in about 50% of Norwegian hospitals and one-third of Danish hospitals. In Norway CAM was offered in 50 hospitals, 40 of which involved acupuncture. 19 hospitals gave other alternative therapies like biofeedback, hypnosis, cupping, ear-acupuncture, herbal medicine, art therapy, homeopathy, reflexology, thought field therapy, gestalt therapy, aromatherapy, tai chi, acupressure, yoga, pilates and other. 9 hospitals offered more than one therapy form. In Denmark 38 hospitals offered acupuncture and one Eye Movement Desensitization and Reprocessing Light Therapy. The most commonly reported reason for offering CAM was scientific evidence in Denmark. In Norway it was the interest of a hospital employee, except for acupuncture where the introduction is more often initiated by the leadership and is more based on scientific evidence of effect. All persons (except one) responsible for the alternative treatment had a medical or allied health professional background and their education/training in CAM treatment varied substantially. The extent of CAM being offered has increased substantially in Norway during the first decade of the 21st century. This might indicate a shift in attitude regarding CAM within the conventional health care system. URI: http://hdl.handle.net/10037/3925 File(s) in this item: 1

Abstract: The primary purpose of this study was to explore the role of variety seeking behaviour towards fish consumption frequency. Second, it aimed to investigate how personality related factors; variety seeking tendency (related to food and personality) and perceived behavioural control affect the nature of variety seeking behaviour. Third, to investigate how product and motivational related factors; attitudes, health involvement and perceived risk affect the nature of variety seeking behaviour and fish consumption in the Sri Lankan context. In line with Hoyer and Ridgway (1984) proposed framework, a conceptual framework was developed with the constructs of variety seeking behaviour, variety seeking tendency (related to food and personality), perceived behavioural control, attitudes, health involvement, perceived risk and fish consumption frequency to achieve the objectives. A questionnaire survey was conducted using a convenience sample of 250 consumers in Galle in Sri Lanka. The items used to measure the constructs were either taken or adopted from the previous research studies. Confirmatory factor analysis and Structural Equation Modeling in AMOS 16.0 were employed to analysis the data. This study found that variety seeking behaviour plays a vital role in fish consumption frequency among consumers. The findings confirmed the theory that variety seeking tendency as a general personality trait positively influences the variety seeking tendency related to food (VST Food) while specific VST Food showing a significant effect on fish consumption frequency. Health involvement was found to be positively significant with fish consumption frequency as well as with the VST Food while having an insignificant relationship with the variety seeking behaviour. Conveneinec/ availability, price/ value and knowledge were not significant indicators of perceived control. Nevertheless, PBC and perceived risk act as a barrier for variety seeking behaviour. However, the effect of perceive risk on the fish consumption frequency was negligible. Surprisingly, attitudes did not have a significant impact on either fish consumption frquency or variety seeking behaviour. The main reason for this is probably skewness of the data set. Practical implications drawn from this research are that fish marketers should tap the consumers’s intrinsic desire for variation through providing different fish species in to the market place. Further, it is suggested that providing information on the most commonly eaten fish species by the government authorities through mass media will reduce the perceived risk and PBC associated with variation of fish and stimulate the health involvement towards variation of fish consumption. This research has contributed to fill the gap in variety seeking behaviour literature in which specifically incorporating effect of both personal related and product/ motivational related factors. This research was based on a convenience sample of consumers which did not represent the whole population, thus the results could not generalize to Sri Lanka. Future research should uncover additional individual and product related factors and their interactions which may relevant to explain variety seeking behaviour.

Abstract: Et av opplysningstidas merkeligste litterære foretak er den berømte franske Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers, under redaksjon av de to vennene Denis Diderot (1713-84) og Jean Le Rond d'Alembert (1717-83). Bind 1 kom ut i juli 1751 (se ill. 1), 2. bind i januar 1752, men i februar samme år ble begge bind forbudt av regjeringen fordi verket ble funnet å være krenkende for religionen og kongens autoritet. I følge sensuren, som hadde som oppgave å beskytte sinnet mot skadelige tanker på samme måte som magen må beskyttes mot fordervet mat, var det forbudt å diskutere kirke og stat. Diderots materiale ble beslaglagt. Men gode venner i Paris, bl.a. Mme de Pompadour, Malesherbes og Choiseul, sørget for et kompromiss. Diderot fikk fortsette mot at tre teologiske oversensorer ble tatt inn i redaksjonen. Men motstanden mot utgivelsen fortsatte og ble intensivert flere ganger. Trykkeren Le Breton drev til og med sin egen sensur ved at han under korrekturen i hemmelighet strøk partier i mange av Diderots artikler, som han fant farlige for sensuren. Dette oppdaget ikke Diderot før utgivelsen hadde kommet til bokstaven "S". URI: http://hdl.handle.net/10037/2167 File(s) in this item: 1

Abstract: Moderne arbeidskraftsutnyttelse kjennetegnes ofte av bakenforliggende vinnings- og eiermotiver. Det er først og fremst i jordbrukssektoren, byggebransjen, verkstedsindustrien, restaurantbransjen og tekstilbransjen at grov utnyttelse av arbeidskraft forekommer. ILO anslår at 12,3 millioner mennesker kan være utsatt for tvangsarbeid på verdensbasis. Av disse er 2,4 millioner ofre for menneskehandel. Straffeloven § 224 første ledd bokstav b oppstiller et individuelt straffansvar for den som er ansvarlig for eller medvirker til menneskehandel med tvangsarbeid som formål. Vi vil i oppgaven diskutere denne bestemmelsen. Videre vil vi diskutere regjeringens tiltak mot menneskehandel. Det vil kunne være gråsoner mellom det som er tvangsarbeid og det som er dårlige arbeidsforhold. Det har i flere år pågått en debatt omkring fenomenet ”sosial dumping”. Vi vil se nærmere på noen av regjeringens tiltak mot sosial dumping og gi noen rettspolitiske betraktninger i tilknytning til dette. EU-retten vil kunne medføre begrensninger på hvilke tiltak norske myndigheter kan iverksette mot sosial dumping. EU-retten kan dermed hindre en effektiv bekjempelse av sosial dumping. Vi vil blant annet vurdere allmenngjøringsordningens forhold til EU/EØS-retten. Oppgaven vil også omhandle noen problemstillinger knyttet til arbeidsinnvandring til Norge. Vi vil vise en kobling mellom grov utnyttelse av personers arbeidskraft og illegalt arbeid. Vi vil i denne sammenheng se nærmere på hvilke konsekvenser det får dersom en arbeidstaker som arbeider illegalt, utsettes for en arbeidsulykke.

Abstract: The aim of this study was to evaluate the longterm outcome in 61 patients with medication-overuse headache (MOH) who 4 years previously had been included in a randomized open-label prospective multicentre study. Sixty patients still alive after 4 years were invited to a follow-up investigation. Fifty patients (83%) participated. Sixteen visited a neurologist, 22 were interviewed through telephone, 2 gave response by a letter, and 10 were evaluated through hospital records. The influence of baseline characteristics on outcome 4 years later was evaluated by non-parametric tests. p values below 0.01 were considered significant. At follow-up, the 50 persons had a mean reduction of 6.5 headache days/month (p\0.001) and 9.5 acute headache medication days/month (p\0.001) compared to baseline. Headache index/month was reduced from 449 to 321 (p\0.001). Sixteen persons (32%) were considered as responders due to a C50% reduction in headache frequency from baseline, whereas 17 (34%) persons met the criteria for MOH. None of the baseline characteristics consistently influenced all five outcome measures. Total Hospital Anxiety and Depression Scale (HADS) score at baseline was predictors (p\0.005) for being a responder after 4 years. At 4 years’ follow-up, onethird of the 50 MOH patients had C50% reduction in headache frequency from baseline. A low total HADS score at baseline was associated with the most favorable outcome.

Abstract: Ved å nærlese sentrale essay i Frilufts-liv. Blade af dagboken (1916) ut fra et estetisk og etisk perspektiv, tydeliggjør jeg i denne oppgaven hvilke meningsdimensjoner som er typiske for Nansens forhold til naturen, og derigjennom også det samfunn som han selv er en del av. Nansens Frilufts-liv tilhører den retningen som på anglo-amerikansk kalles nature writing. Av min undersøkelse kommer det frem at Frilufts-liv kan sies å inngå som en del av denne tradisjonen og at Fridtjof Nansen på mange måter er det norske svaret på Henry David Thoreau, med hans bøker Walden og The Maine Woods. Nansens ulike opphold i naturen bidrar med å gi han perspektiv på, og innsikt i skyggesider ved kulturen og samfunnet. Han er bekymret for utviklingen og de vilkår mennesket lever under. Slik han ser det, fører samfunnsutviklingen til at de åndelige aspektene ved tilværelsen blir stadig mer fraværende, noe som går ut over relasjonen mennesket har til seg selv, til hverandre og til naturen. Nansen skildrer et samfunn som har havnet på feil spor, og spår katastrofale følger for menneskeheten om ikke toget endrer kurs. I Frilufts-liv tar Nansen leseren med inn i naturen for å vise at mennesket kanskje må søke det opprinnelige for å finne kimen til det som kan bygge et bedre samfunn. Livet i naturen er for Nansen synonymt med en forenklet tilværelse, som bidrar med å frigjøre mennesket fra det kompliserte i bysfæren. Bylivet kategoriseres som komplisert fordi det er preget av tids- og motejag og en uendelig strøm av nye inntrykk. Dette villeder mennesket og fører det bort fra sin egen autentisitet og personlighet. I naturen finner Nansen imidlertid rom til både fordyping og ro, en fri og ukomplisert væren, hvor det enkle livet kan dyrkes. Av mine nærlesninger kommer det frem at det er Nansens erfaringer fra Arktis som har gitt ham innsikten i verdien av det enkle. Disse erfaringene er implisert i hans syn på forholdet mellom menneske og natur, noe som preger friluftslivet som han forfekter, men også det jeg har valgt å betegne som hans ideologiske prosjekt. Arne Næss har videreutviklet denne ideologien, og idéen om forenkling er en viktig del av Næss` økosofi og dypøkologi. Nansen bidro med å forme og gi det norske friluftsliv en egenart og et ideologisk innhold, noe som revitaliseres hos flere av de norske miljøfilosofene på 1970-tallet. Det blir hevdet at naturen i vår tid avmystifiseres og i større og større omfang blir uttrykt gjennom naturvitenskapens reduksjonistiske termer. Gjennom sin inntrykksømhet viser Nansen en unik evne til å se det store i det små, og gjennom sin mythopoetiske tilnærming til naturen gjør han naturmøtet svært meningsladd. Nansen er derfor et forbilde med tanke på vår egen samtids avmystifiserte naturforståelse. Arne Næss og Fridtjof Nansen var begge opptatt av sammenhengen mellom vår eksistens og naturen og forener forbindelsen mellom menneske og natur gjennom bruk av mystikk, symbolikk og fantasi og dyp undring. De gir begge plass til en åndelig dimensjon i en høyst vitenskapelig og rasjonell verden, uten at det nødvendigvis ligger noe transcendentalt, hinsidig eller religiøst bak deres natursensibilitet.

Abstract: Norsk laksenæring har i all hovedsak vært drevet av en volumstrategi hvor det skapes verdier gjennom økt effektiv drift, lave produksjonskostnader og vekst i volum. Norsk laks blir av den grunn betraktet som homogene standardvarer hvor pris er den viktigste konkurransevariabelen. Gjennom å utvikle mer bearbeide produkter er det mulig for bedrifter å kreve høyere pris på laksen, samt oppnå en mer stabil inntjening. Denne studien har derfor tatt utgangspunkt i et utvalg av norske laksebedrifter som fokuserer på å differensiere seg gjennom å tilby mer bearbeidede lakseprodukter. Funnene fra studien indikerer at bedriftene er i stor grad kundesentrerte som et resultat av deres differensieringsvalg. Det ble identifisert 15 ulike differensieringsdimensjoner noe som tyder på at bedriftene vektlegger ulike og flere kilder til fortrinn, hvorav 10 av dem anses som midlertidige kilder til fortrinn, mens 5 burde gi grunnlag for varige konkurransefortrinn. Fordeler som bedriftene oppnår gjennom differensiering er høye priser, profitt, faste og langsiktige kontrakter med stabile priser, positivt omdømme, bedriftsinterne fordeler og risiko redusering i forhold til utbrudd av lakselus. Studien kommer med en anbefaling om at bedriftene må kontinuerlig investere i kilder til fortrinn for at disse skal være varige. URI: http://hdl.handle.net/10037/2117 File(s) in this item: 1

Abstract: This thesis presents the design and implementation of Distributed OpenSceneGraph. Distributed OpenSceneGraph is a graphics visualization toolkit for distributed applications, in particular for tiled display wall systems. Distributed OpenSceneGraph allows for flexible and reasonably transparent development of distributed graphics applications by introducing the notion of distributed nodes into the well know OpenSceneGraph graphics toolkit. By letting the Distributed OpenSceneGraph only concern itself with the state of individual scene graph nodes we achieve a great degree of flexibility. It is not in any way enforced that the local scene graph copies in any of the processes that make up the distributed system must be identical, nor is it necessary that all or any of the distributed nodes in the total distributed application be present in a processes scene graph copy. This enables an application developer to create applications with radically different scenes while still distributing what needs to be. An important focus when implementing Distributed OpenSceneGraph was transparency. Therefore a lot of effort has been laid into enabling application developers to use Distributed OpenSceneGraph with only a few extra function calls beyond what they would have encountered when creating undistributed OpenSceneGraph applications. The flexibility and transparency introduced to visualization of application data makes Distributed OpenSceneGraph suitable for use in the development of distributed graphics applications. At time of writing the Distributed OpenSceneGraph library is unfortunately not quite finished. However a number of measurements and possible solutions are presented to show the path onwards.

Six seismic units and eight seismic unconformities, including the seafloor, are identified in the study area and correlated with previous work in the Sørvestnaget Basin. Submarine channels with a downslope (E-W) orientation suggest a glacimarine environment, i.e. the channels are inferred to have been formed by turbidity currents originating from glacial meltwater on the deepest reflector. On shallower reflectors, megascale glacial lineations, ridges and parts of hill-hole pairs indicate that grounded ice reached the paleo-shelf edge at least six times in the last 1.5 Ma. Moreover, two of the shallower seismic units show indications of sediment blocks that are inferred to have been subglacially eroded, transported and deposited by ice streams. The influence of the ice stream flowing from the Bjørnøyrenna in the last 330 ka is evident in the Veslemøy High; however, the origin of the ice streams is unclear on older paleo-surfaces.
