Abstract: Acculturation is for indigenous peoples related to the process of colonisation over centuries as well as the on-going social transition experienced in the Arctic today. Changing living conditions and lifestyle affect health in numerous ways in Arctic indigenous populations. Self-rated health (SRH) is a relevant variable in primary health care and in general public health assessments and monitoring. Exploring the relationship between acculturation and SRH in indigenous populations having experienced great societal and cultural change is thus of great importance. The principal method in the Survey of Living Conditions in the Arctic (SLiCA) was standardised face-to-face interviews using a questionnaire. Very high overall participation rates of 83% were obtained in Greenland and Alaska, whilst a more conventional rate of 57% was achieved in Norway. Acculturation was conceptualised as certain traditional subsistence activities being of lesser importance for people’s ethnic identity, and poorer spoken indigenous language ability (SILA). Acculturation was included in six separate gender- and country-specific ordinal logistic regressions to assess qualitative effects on SRH. Multivariable analyses showed that acculturation significantly predicted poorer SRH in Greenland. An increased subsistence score gave an OR of 2.32 (P<0.001) for reporting poorer SRH among Greenlandic men, while an increased score for Greenlandic women generated an OR of 1.71 (P=0.01). Poorer SILA generated an OR of 1.59 in men (p=0.03). In Alaska, no evidence of acculturation effects was detected among Iñupiaq men. Among Iñupiaq women, an increased subsistence score represented an increased odds of 73% (p=0.026) for reporting poorer SRH. No significant effects of acculturation on SRH were detected in Norway. This study shows that aggregate acculturation is a strong risk factor for poorer SRH among the Kalaallit of Greenland and female Iñupiat of Alaska, but our cross-sectional study design does not allow any conclusion with regard to causality. Limitations with regard to wording, categorisations, assumed cultural differences in the conceptualisation of SRH, and confounding effects of health care use, SES and discrimination, make it difficult to appropriately assess how strong this effect is though.

Abstract: Trauma affects children from all races, ethnicities, nationalities and socio-economic backgrounds. However, indigenous children may experience trauma differently than their majority population peers due to traumatic histories of colonization and ongoing marginalization. This thesis explores how service providers in Western Montana and Northern Norway conceptualize Native American and Sámi children’s experiences of trauma today. Additionally, I ask if these providers draw links between the historical traumas of the past and current traumatic events facing indigenous children in these two locations. Interviewees spoke about the effects of historical trauma in eight identified themes. The diversity of the themes and concepts discussed imply that providers regard their indigenous clients as being impacted by the historical traumas suffered by indigenous peoples in Montana and Northern Norway. Acknowledging past histories of injustice and focusing future research on the unique resiliencies of indigenous children, families, and communities were two main recommendations for promoting the treatment and understanding of indigenous child trauma. The thesis provides a brief look into the experiences of Native children in Montana and Sámi children in Norway facing trauma, as seen from the eyes of their social workers, therapists and advocates.

Abstract: An acquired loss of renal DNaseI has recently been shown to promote transformation of mild mesangial lupus nephritis into membrano-proliferative end-stage organ disease. In this study, we analyzed expression profiles of DNaseI in other organs of lupus-prone (NZBxNZW)F1 mice during disease progression to determine if silencing of the renal DNaseI gene is an organ specific feature or if loss of DNaseI reflects a systemic error in mice with sever lupus nephritis. Our results demonstrate normal or elevated levels of DNaseI mRNA and enzyme activity in liver, spleen and serum samples of (NZBxNZW)F1 mice throughout all stages of lupus nephritis. DNaseI activity was dramatically reduced only in kidneys of mice with sever nephritis and was the only nuclease that was down-regulated, while 6 other nucleases (DNaseIl1-3, caspase activated deoxyribonuclease, Dnase2a, and endonuclease G) were largely normally expressed in kidneys, liver and spleen. Loss of renal DNaseI was not accompanied by changes in serum DNaseI activity, suggesting an independent mechanism of DNaseI regulation in circulation and in kidneys, and an absence of compensatory upregulation of serum DNaseI activity in case of renal DNaseI deficiency. Thus, silencing of renal DNaseI is a unique renal feature in membrano-proliferative lupus nephritis. Determination of mechanism(s) responsible for DNaseI down-regulation is a future step in generation of new therapeutic targets to treat and prevent progressive lupus nephritis.

Abstract: This thesis focuses on the most recent OT-based theory of opacity called Optimality Theory with Candidate Chains (OT-CC, see McCarthy 2007). To date very little attention has been dedicated to the problem of acquisition of OT-CC grammars and to the treatment of spontaneous opacity effects in the light of OT-CC. In this thesis it is demonstrated that OT-CC grammars can be effectively learned by the BCD algorithm (Prince & Tesar 2004). Also, on the basis of evidence from obligatorily counterbleeding processes, NDEBs and non-target-like opacity effects, it is proposed to make certain changes to the status of Precedence constraints with the view to increase the descriptive adequacy of OT-CC. It is shown that the proposed adjustments allow OT-CC to account for emergence and subsequent loss of spontaneous opacity effects, as well as for the phenomenon of U-shaped learning and cross-subject variation in early production data.

Abstract: This thesis looks at how Norwegian learners of English acquire the English laryngeal feature distribution in two types of suffixes; s-endings and the past tense. The past tense forms are distributed almost identically in both Norwegian and English, only differing after sonorants. The s-endings in Norwegian are all voiceless, whereas in English these behave in a parallel way to the past tense. A cross-sectional study of Northern Norwegian learners in three age-groups, year 9, 11 and 13, were conducted, and the results from this study make up the foundation for the analyses. Two learning algorithms; the Gradual Learning Algorithm (GLA) and the Error Driven Constraint Demotion principle (EDCD) were applied to the data. I argue that the GLA cannot account for the findings, whereas the EDCD can. The GLA’s promotion principle works against its purpose as it triggers constraints to move in a fashion which leads to inter language grammars that are not to be found. The EDCD is found to be the algorithm that best describes the Norwegian learners’ patterns as it makes use of universal constraints that are hidden in the native language of the learners, and so can explain the difference in acquisition rate between certain patterns. At the same time it rejects the principle of constraint promotion and therefore does not run into the same problems as the GLA. URI: http://hdl.handle.net/10037/1088 File(s) in this item: 1

Abstract: Very little is known about introgression in bacteria. Introgression is the process where the genes of one species infiltrate the gene pool of another organism by subsequent backcross transformations of a hybrid with one of its parents. After the initial acquisition of foreign DNA, DNA from the newly made transformants is used as donor DNA in backcross transformations with the recipient. DNA is released to the environment after decomposing of dead cells, disrupting of cells or through excretion from living organisms. The extracellular DNA can be degraded after release, thus fragmented DNA can be taken up by bacteria. One previous unpublished study investigated the effect of introgression of foreign unselected DNA. The donor DNA in this study was of high molecular weight (20 to 30 kilo bases (Kb)) and it was suggested that introgression in backcross transformation could be a mechanism by which unselected DNA was eliminated from the genome. I wanted to study the effect of introgression when the foreign donor DNA was of low molecular weight (1000 to 4000 base pairs (bp)). We wanted to determine how fragmentation affects the speed at which unselected DNA from Acinetobacter sp. strain 16.4 was eliminated from the genome of Acinetobacter baylyi strain BD413 during the introgression process. I have developed a method for optimal fragmentation of DNA to the desired size for this study. The DNA was fragmented by sonication, which gave an effective, gradual reduction in the fragment size of DNA. The size of the sonicated DNA was checked on an agarose gel and I found out that a gel fraction between 1000 to 4000 bp was the desired size for fragmented DNA. The DNA was extracted from the gel piece and used as low molecular weight donor DNA. This method can be used to determine the effect of introgression when the foreign donor DNA is of low molecular weight (1000 to 4000 base pairs bp) and to get a better understanding for natural fragmentation of extracellular DNA in the environment.

Abstract: Gemcitabine is a well established anticancer compound, and is in use today against several types of cancers. Gemcitabine has a short half life. Formulations of gemcitabine containing liposomes could extend it's half life, thereby maybe improving its effectiveness. Also, liposomes in the smaller size range have an advantage when it comes to treating cancer. They accumulate at the site of the tumor, and stay there for a longer time than it would have done in normal tissue(Massing and Fuxius 2000). Previous attempts to actively load gemcitabine into liposomes have used a pH gradient with acidic pH inside compared to more neutral pH on the outside of the liposomes, accomplished by an ammonium sulphate gradient. But this approach showed some difficulties; among other things that gemcitabine had a tendency to leak out in very short time. (Gravem 2006). In this thesis I have among other things investigated the possibility of loading gemcitabine into liposomes by precipitation. The hope was that this could give higher trapping efficiency and reduced leakage compared to the ammonium sulphate approach. Firstly, for comparable reasons and method development, an approach to load liposomes via an ammonium sulphate gradient was tried. Thought after encountering several problems the experiment was ended without any results indicating loading, most likely due to heavily diluted liposomes. Secondly I investigated if I could make gemcitabine precipitate. Firstly I tried a great range of different phosphate and sulphate salts, to test if any of them would cause a precipitation. Precipitation seemed to be independent of which salt used, but enhanced by factors such as high concentration of gemcitabine, alkaline conditions (pH ≥ 6), and low temperature. The two last conditions were the total opposites of loading via an ammonium sulphate gradient, and contained several contradictions as it meant that the outer pH had to be significantly lower to avoid precipitation and that a low temperature made it harder for gemcitabine to cross the membrane of the liposomes. An attempt to load gemcitabine into liposomes, using a pH 4 in the outer phase and pH 7 in the inner phase of the liposomes, with repeated cooling and freezing cycles, revealed poor loading. Thought optimizing conditions such as pHs, and time and temperatures in the cooling freezing cycles might enhance the loading a bit it is difficult to see this approach becoming a success.

Abstract: Chronic musculoskeletal pain is a common health problem and a major cause for disability pension in Norway. Increased pain and fear related to general activity and exercise may be a barrier to rehabilitation of patients with chronic muscular-skeletal disorders.
The aim of the present research was to investigate the occurrence of activity related pain, and to explore its association with fear, psychological distress, self efficacy and pain (duration and distribution). The second aim was to explore how these psychological aspects and activity related pain associates with individuals’ readiness to adopt a self-management approach to pain, and how patients described and explained such pain experiences.
Data were collected by questionnaires and qualitative interviews with out-patients at a Physical Medicine clinic at the University Hospital of Northern Norway. Results showed that a majority of the participants experienced increased pain during activity. Pain related fear of movement/(re)injury was a unidimensional construct, which was statistically significantly associated with increased pain during activity, also among individuals without psychological distress. Participants with high levels of fear of movement/(re)injury and psychological distress and weak sense of (pain) self efficacy were more likely to report pain during activity. They were also less ready to take a self-management approach to pain. Activity related pain was described and explained as a complex experience with diverse meanings. Initial fear of pain was re-interpreted under the influence of time, learning and own experience. Participating in social life situations was an important incentive to stay active despite pain.URI: http://hdl.handle.net/10037/2500 File(s) in this item: 6

Abstract: Purpose. Activity related pain may be a barrier to rehabilitation in patients with chronic musculoskeletal disorders. This study investigated patients’ reports of increased pain during activity, and the association between such pain and psychological factors and pain variables. Method. Questionnaires from 232 adults with chronic musculoskeletal pain measured pain intensity, spread of pain and pain duration. Pain during activity was assessed both on a 11 point Numeric Rating Scale (NRS), and operationalized as a dichotomous measure, where responders defined if they experienced pain during general activity and exercise. Psychological factors were measured by the Hopkins Symptom Check List 25, the Tampa Scale for Kinesiophobia and a subscale of the Arthritis Self – Efficacy Scale. Multiple and logistic regression was used to analyse associations between increased pain during activity and associated variables. Results. Increased pain during activity was reported by 69 % of participants. Fear of movement was a significant factor for reporting increased pain during activity, both general activity and exercise, also in a subsample with low psychological distress. Other significant factors were spread of pain and a low sense of self efficacy. Conclusion. Patients with high fear of movement, large spread of pain and low self efficacy were more likely to report increased pain during activity even in the absence of psychological distress.

Abstract: Background:For more than 2000 years acupuncture has been used to treat depression and randomized controlled trials (RCT) have been conducted to investigate their efficacy.Objectives: The objectives of this overview is to assess the effects and adverse effects of acupuncture in patients with depression, and to evaluate the report quality of acupuncture treatment for depression in randomized controlled trials and systematic reviews. Search Strategy: Six different electronical databases were searched, combined with manual searches in journals of interest and reference lists. Selection Criteria:Systematic reviews and randomiced trials of acupuncture for depression compared to medication, waiting list, non-spesific acupuncture and placebo were included.Main Result:Four systematic reviews and eighteen RCTs were analyzed. The methodological quality of trials reports were generally low. A significant reduction in depression was found by electro-acupuncture compared to antidepressant medication.And a significant beneficial effects was found for classical acupuncture in improving and reducing depression compared to placebo. Conclusion: More rigorouse trials are needed and long-term effects should be investigated if acupuncture is to be recommended as one of the alternative treatments for depression.

Abstract: Summary Petroleum exploitation is emerging in the Arctic. In the Norwegian Arctic the southern Barents Sea is opened for development of oil and gas fields. This same area holds some of the world's largest and well managed commercial fish stocks such as Herring (Clupea harengus), Capelin (Mallotus villosus), Haddock (Melanogrammus aeglefinus), Atlantic Cod (Gadus morhua). For the interest of the fishing industry, as well as for maintaining a healthy ecosystem, petroleum related Environmental Risk Assessments (ERA) for the Barents Sea must be based on sound scientific knowledge of the special features of the Arctic ecosystem. In colder areas the physical behavior of oil is different compared to warmer areas. The lower temperature and lack of sun light during the Arctic winter slows down the natural physical weathering process of oil. In ERA in temperate areas the effects of exposure to the most volatile fraction of the oil are neglected due to short exposure time. However, in the Arctic the exposure to biota of this volatile fraction may be prolonged due to lower evaporation rates and the volatile fraction may be an important contributor to the overall adverse effect of an oil spill. Likewise, the exposure to the heavier oil fractions may be prolonged and knowledge on the long-term effects of exposure is essential. As an adaptation to the Arctic environment species found here have longer life spans, larger body sizes and higher lipid contents compared to temperate equivalent species. Thus Arctic species may accumulate contaminants over longer time and reach higher life time body levels. Meanwhile higher lipid content implies a higher affinity of lipophilic contaminants such as polycyclic aromatic hydrocarbons (PAHs). So, Arctic species may be exposed to oil compounds for a longer time because of the prolonged phycical presence and may, due to special adaptive features, be more efficient at accumulating oil contaminants. Today the knowledge of effects of oil contaminants on Arctic biota is limited, but growing. This thesis addresses a few of the research challenges in the field and provides knowledge on some effects of petroleum exposure to two copepod species; the sub-Arctic Calanus finmarchicus and the Arctic sibling species C. glacialis. First, Calanus was cultured for a generations under sub-Arctic conditions (Paper I). This work establishes that Calanus is suitable for ecological relevant long-term experiments. In an oil spill scenario, Arctic copepods and algae may be exposed to the more volatile fraction of the oil. Paper II provides data showing that the Arctic diatom species, Fragilariopsis oceanica, was the most sensitive species to exposure to the volatile hydrocarbon xylene. Further, the smaller, less lipid rich copepod species C. finmarchicus, was more sensitive compared to the true Arctic C. glacialis. Extrapolating these results to a spill situation, C. finmarchicus and C. glacialis populations would be affected by xylene exposure through both direct exposure (mortality) and indirectly through a decline in prey organisms (algae). Sub-lethal effects after long-term exposures to low concentrations of oil compounds may also be detected in C. finmarchicus and C. glacialis. Feeding was suppressed in C. finmarchicus after exposure to 7.0 µg PAHs l-1 for 11 days (Paper III). No significant effect on feeding was detected in C. glacialis exposed to 10.4 µg PAHs l-1 for 11 days. However, the hatching success of eggs laid by females exposed to 10.4 µg PAHs l-1 for two days was significantly reduced (Paper III). The long term effects of lipophilic PAHs in biota depend on the bioaccumulation capacity and internal concentrations of the various PAHs. Accumulation of lipophilic compounds is particularly important for the lipid rich Arctic species. Paper IV examines the uptake kinetics of two PAHs in C. finmarchicus and show that the accumulation of the lighter and less lipophilic compound, phenanthrene, is faster that the uptake of the heavier and more lipophilic benzo[a]pyrene (B[a]P). Equilibrium was reached for phenanthrene within 192 h exposure while no equilibrium was detected for B[a]P. The bioconcentration factor (BCF) was higher for B[a]P, reflecting the higher affinity for lipids of B[a]P compared to phenanthrene (Paper IV). So the heavier, more lipophilic PAH accumulates slower but to a higher concentration in C. finmarchicus. This thesis shows that not only acute but also long-term exposures may affect Arctic species. In addition, exposure duration may determine which compounds are accumulated by biota. Both indirect effects, such as decrease of food items, and direct effects, such as mortality, reduced feeding and reproduction failure may have implications for population development. These findings should be taken into consideration when developing ERA for the Barents Sea area. Description: Papers 1 and 2 of this thesis are not available in Munin:

Abstract: Akutt hjertesvikt, spesielt ved sirkulatorisk kollaps, er en dramatisk tilstand med høy dødelighet. Forekomsten av akutt hjertesvikt er økende og tilgjengelig kunnskap om sykdomsmekanismene samt medisinsk behandling er begrenset.De siste tiår har det vært en revolusjonerende utvikling i behandlingen av og overlevelsen ved iskemisk hjertesykdom og akutt hjerteinfarkt. Tilsvarende utvikling har det dessverre ikke vært i behandlingen av akutt hjertesvikt som er et økende problem assosiert med høy dødelighet. Formålet med dette prosjektet har vært å kartlegge epidemiologi, behandling og prognose ved forskjellige typer akutt hjertesvikt. For å øke den patofysiologiske forståelsen av sirkulasjonsregulering ved de mest alvorlige former for akutt hjertesvikt (kardiogent sjokk) har vi gjennomført observajonsstudier av biokjemiske responser og perifer karfunksjon i sykdomsforløpet. Prosjektet har vært todelt. Vi har først har sett på forekomsten av forskjellige typer akutt hjertesvikt og behandlingen som ble gitt ved medisinsk og kirurgisk intensiv avdeling ved UNN over en 2 års periode. Tross moderne behandling med bla tidlig revaskularisering døde ca 1/4 av pasientene under sykehusoppholdet. Dårligst prognose hadde de med kardiogent sjokk der nesten halvparten døde. De med lettere former for akutt hjertesvikt hadde meget dårlige leveutsikter i perioden etter utskrivelse og kun 50 % var i live etter to år. Mer utstrakt og tidlig bruk av mekanisk sirkulasjonsstøtte (hjertepumper) kan potensielt bedre overlevelsen hos de med mest alvorlig og behandlingsrefraktær hjertesvikt. Hos pasienter med kardiogent sjokk og alvorlig hjertesvikt etter hjertekirurgi er dårlig respons på konvensjonelle blodtrykksøkende medikamenter forbundet med spesielt dårlig prognose. For å kartlegge de underliggende mekanismene ved sirkulasjonssvikt spesielt mtp perifer sirkulasjonsregulering har vi målt perifer karfunksjon (endotelfunksjon), markører på systemisk inflammasjon og sirkulerende NO-blokkere (ADMA) under sykdomsforløpet. Tilstanden var karakterisert av en betydelig systemisk inflammasjon samt redusert perifer karfunksjon. Høye nivå av ADMA var assosiert med organsvikt og graden av hypoperfusjon.

Abstract: Background: Over the last decades there has been an increasing pressure on the acute psychiatric wards in Norway. The major contributor to psychiatric acute admissions at the University Hospital of North Norway in the city of Tromsø in 2001 was the GP-based Tromsø Casualty Clinic, only open out-of-hours. We explored all acute psychiatric referrals from Tromsø Casualty Clinic in 2001. The purpose of the study was to characterize the admissions and assess the agreement between the referring doctors and the hospital specialists according to the need for hospitalization, agreement on application of the law and the diagnostic evaluation to assess whether the admissions were appropriate. Methods: Retrospective, record based, descriptive study comprising 101 psychiatric acute referrals from the Tromsø Casualty Clinic to the psychiatric acute wards at the University Hospital of North Norway. Results: The specialists accepted all referrals except one, they mostly agreed upon the diagnoses suggested by the referring doctors and they mostly confirmed the application of the law. Seventy-five percent of the admissions took place during weekends, public holidays or nighttimes. Diagnoses of psychoses or suicidal attempts accounted for 76 % of the total referrals. Substance abuse was noted for 43 %, and in 22 % of all admissions the patients had stopped taking their psychopharmacological medication. The police assisted the referring doctors in one third of all admissions, and was the legal representative in 52 out of 59 involuntary admissions. Thirty percent of the admissions were first- time admissions. Thirty-two percent of the hospital stays lasted for three days or less. Median length of stay was 6.5 days. Conclusion: The casualty clinic physicians and the hospital specialists mostly agreed in their evaluation of patients indicating that most of the admissions were appropriate. The police was more often involved in the involuntary admissions than intended in the law. The proportion of patients with substance abuse was significant. Alternative treatment strategies should be developed for non-psychotic patients in need of short-term stays. URI: http://hdl.handle.net/10037/1118 File(s) in this item: 1

Abstract: Sympatric occurring fish morphs in postglacial lakes usually exhibit differences in morphology and physiology driven by adaptations to differential trophic niches. The European whitefish (Coregonus lavaretus (L.)) is a highly variable fish species, with more than 200 intraspecific forms described in Europe. The morphs usually differ in their number of gill-rakers, therefore this trait has been traditionally used for whitefish classification. According to this taxonomy, three different morphs can be distinguished in northern Fennoscandia: the large sparsely rakered (LSR), the densely rakered (DR), and the small sparsely rakerd (SSR) morphs. They all exhibit differences in morphology, diet, habitat, and physiology. Recently, a new morph has been discovered in several lakes of the Pasvik watercourse which displays densely rakered gills and an external morphology similar to the LSR whitefish, and was called large densely rakered (LDR). In this study, genetic data from 18 microsatellites markers were used to evaluate the genetic differentiation and the possible origin of this new morph in three Finnish lakes of the Pasvik watercourse. The LDR morph in each lake was found to be genetically different from the three other morphs. Several possible origins were suggested, but the sympatric speciation from either the LSR or the DR morphs was the hypothesis that gained the most support from the results. Moreover, the three different LDR populations were found to have a common origin, suggesting that the divergence occurred only once after the last ice retreat and the same population divided into three when the different lakes were formed.

Abstract: In this paper we will show that it is possible to combine mobile agent technology with existing non-mobile data mining applications. The motivation for this is the advantage mobile agents offer in moving the computation closer to the data in a distributed system. This can save bandwidth and increase performance when the data is condensed as a result of data mining. URI: http://hdl.handle.net/10037/357 File(s) in this item: 1

Abstract: Oppgavens problemstilling er hvor langt adgangen til å formidle personopplysninger innen det lokale NAV- kontoret rekker. Herunder drøftes muligheten for kommunikasjon mellom ansatte, og grensen for hva ansatte kan ha tilgang til av opplysninger i arkiv, fagsystemer o.l. Viktige spørsmål i denne sammenheng, er om NAV- kontoret er ett organ, og hvordan adgangen til å formidle personopplysninger påvirkes der det er lagt oppgaver til kontoret utover minimumskravet i NAV- loven § 13. Gjenstanden for drøftelsen er reglene for behandling av personopplysninger i arbeids- og velferdsforvaltningen, og herunder er det taushetspliktsreglene som får størst fokus. Ledelsens ansvar for personopplysningsvernet, herunder ansvaret for å gi ansatte tilgangsbegrensninger i fagsystemer og arkiv, drøftes også.
