- DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To construct and internally validate a risk score, the '80+ score', for revisits to hospital and mortality for older patients, incorporating aspects of pharmacotherapy. Our secondary aim was to compare the discriminatory ability of the score with that of three validated tools for measuring inappropriate prescribing: Screening Tool of Older Person's Prescriptions (STOPP), Screening Tool to Alert doctors to Right Treatment (START) and Medication Appropriateness Index (MAI). Setting: Two acute internal medicine wards at Uppsala University hospital. Patient data were used from a randomised controlled trial investigating the effects of a comprehensive clinical pharmacist intervention. Participants: Data from 368 patients, aged 80 years and older, admitted to one of the study wards. Primary outcome measure: Time to rehospitalisation or death during the year after discharge from hospital. Candidate variables were selected among a large number of clinical and drug-specific variables. After a selection process, a score for risk estimation was constructed. The 80+ score was internally validated, and the discriminatory ability of the score and of STOPP, START and MAI was assessed using C-statistics. Results: Seven variables were selected. Impaired renal function, pulmonary disease, malignant disease, living in a nursing home, being prescribed an opioid or being prescribed a drug for peptic ulcer or gastroesophageal reflux disease were associated with an increased risk, while being prescribed an antidepressant drug (tricyclic antidepressants not included) was linked to a lower risk of the outcome. These variables made up the components of the 80+ score. The C-statistics were 0.71 (80+), 0.57 (STOPP), 0.54 (START) and 0.63 (MAI). Conclusions: We developed and internally validated a score for prediction of risk of rehospitalisation and mortality in hospitalised older people. The score discriminated risk better than available tools for inappropriate prescribing. Pending external validation, this score can aid in clinical identification of high-risk patients and targeting of interventions.

Tidskriftsartikel (refereegranskat)abstract
- Importance: Older patients with multiple co-morbidities and multi-drug use are at high risk of revisits to hospital and mortality, which poses an increasing health economic burden.Objective: To construct and internally validate a risk score, the “80+ score”, for revisits to hospital and mortality for older patients, incorporating aspects of pharmacotherapy. Our secondary aim was to compare the discriminatory ability of the score with that of three validated tools for measuring inappropriate prescribing: Screening Tool of Older Person’s Prescriptions (STOPP), Screening Tool to Alert doctors to Right Treatment (START) and Medication Appropriateness Index (MAI).Design: Secondary use of data from a randomized controlled trial investigating effects of a comprehensive pharmacist intervention, conducted in 2005-2006.Setting: Two acute internal medicine wards at Uppsala University hospital.Participants: Data from 368 patients, 80 years and older, admitted to one of the study wards.Main outcomes and measures: Time to rehospitalization or death during the year after discharge from hospital. Candidate variables were selected among a large number of clinical and drug-specific variables. After a selection process, a score for risk-estimation was constructed. The score was internally validated, and the discriminatory ability of the new score and of STOPP, START and MAI was assessed using C-statistics. Results: Seven variables were selected for the 80+ score. Impaired renal function, pulmonary disease (chronic obstructive pulmonary disease [COPD or asthma]), malignant disease (past or present), living in nursing home, being prescribed an opioid or being prescribed a drug for peptic ulcer or gastroesophageal reflux disease was associated with an increased risk, while being prescribed an antidepressant drug (tricyclic antidepressants not included) was linked to a lower risk of the outcome. These variables made up the components of the 80+ score. The C-statistics were 0.71 (80+ score), 0.57 (STOPP), 0.54 (START) and 0.63 (MAI). Conclusion and Relevance: We developed and internally validated a score for prediction of risk of rehospitalization and mortality in hospitalized older people. The score discriminated risk considerably better than available tools for inappropriate prescribing. Pending external validation, this score can aid in clinical identification of high-risk patients and targeting of interventions.

Improving the Quality and Safety of Drug Use in Hospitalized Elderly : Assessing the Effects of Clinical Pharmacist Interventions and Identifying Patients at Risk of Drug-related Morbidity and Mortality
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Older people admitted to hospital are at high risk of rehospitalization and medication errors. We have demonstrated, in a randomized controlled trial, that a clinical pharmacist intervention reduces the incidence of revisits to hospital for patients aged 80 years or older admitted to an acute internal medicine ward. The aims of this thesis were to further study the effects of the intervention and to investigate possibilities of targeting the intervention by identifying predictors of treatment response or adverse health outcomes.The effect of the pharmacist intervention on the appropriateness of prescribing was assessed, by using three validated tools. This study showed that the quality of prescribing was improved for the patients in the intervention group but not for those in the control group. However, no association between the appropriateness of prescribing at discharge and revisits to hospital was observed.Subgroup analyses explored whether the clinical pharmacist intervention was equally effective in preventing emergency department visits in patients with few or many prescribed drugs and in those with different levels of inappropriate prescribing on admission. The intervention appeared to be most effective in patients taking fewer drugs, but the treatment effect was not altered by appropriateness of prescribing.The most relevant risk factors for rehospitalization and mortality were identified for the same study population, and a score for risk-estimation was constructed and internally validated (the 80+ score). Seven variables were selected. Impaired renal function, pulmonary disease, malignant disease, living in a nursing home, being prescribed an opioid and being prescribed a drug for peptic ulcer or gastroesophageal reflux disease were associated with an increased risk, while being prescribed an antidepressant drug (tricyclic antidepressants not included) was linked with a lower risk. These variables made up the components of the 80+ score. Pending external validation, this score has potential to aid identification of high-risk patients.The last study investigated the occurrence of prescription errors when patients with multi-dose dispensed (MDD) drugs were discharged from hospital. Twenty-five percent of the MDD orders contained at least one medication prescription error. Almost half of the errors were of moderate or major severity, with potential to cause increased health-care utilization.

The effects of pharmacist intervention on emergency department visits in patients 80 years and older : subgroup analyses by number of prescribed drugs and appropriate prescribing
- 2014
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 9:11, s. e111797-
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Clinical pharmacist interventions have been shown to have positive effect on occurrence of drug-related issues as well as on clinical outcomes. However, evidence about which patients benefiting most from the interventions is limited. We aimed to explore whether pharmacist intervention is equally effective in preventing emergency department (ED) visits in patients with few or many prescribed drugs and in those with different levels of inappropriate prescribing. Methods: Patient and outcome data from a randomized controlled trial exploring the clinical effects of a ward-based pharmacist intervention in patients, 80 years and older, were used. The patients were divided into subgroups according to the number of prescribed drugs (< 5 or >= 5 drugs) and the level of inappropriate prescribing [using the Screening Tool Of Older People's potentially inappropriate Prescriptions (STOPP) and the Screening Tool to Alert doctors to Right Treatment (START) with a score of >= 2 (STOPP) and >= 1 (START) as cutoff points]. The effect of the intervention on the number of times the different subgroups visited the ED was analyzed. Results: The pharmacist intervention was more effective with respect to the number of subsequent ED visits in patients taking < 5 drugs on admission than in those taking >= 5 drugs. The rate ratio (RR) for a subsequent ED visit was 0.22 [95% confidence interval (CI) 0.09-0.52] for,5 drugs and 0.70 (95% CI 0.47-1.04) for >= 5 drugs (p = 0.02 for the interaction). The effect of intervention did not differ between patients with high or low STOPP or START scores. Conclusion: In this exploratory study, the pharmacist intervention appeared to be more effective in preventing visits to the ED for patients who were taking fewer drugs before the intervention. Our analysis of STOPP and START scores indicated that the level of inappropriate prescribing on admission had no effect on the outcomes of intervention with respect to ED visits.

Kontextförlust och kontextkollaps : Metodproblem vid innehållsanalys av sociala medier
- 2016
-
Ingår i: Nordicom Information. - Göteborg : Nordicom. - 0349-5949. ; 38:3, s. 41-55
-
Tidskriftsartikel (refereegranskat)abstract
- The article proposes that social media platforms enable large volumes of user-driven circulation of media content, and argues for a combination of qualitative and quantitative considerations when analysing data from such platforms. Issues of context are vital; context must be understood both qualitatively (cultural setting) and quantitatively (statistical reference points for comparison). The authors emphasise that the possibilities of ‘big data’ should not tilt analyses so that sensitivities to subtler meanings are lost. By examining a recent research project of our own, examples are given of how topological network analysis can be successfully combined with close readings of strategically selected parts of the data and how, by doing so, context shifts can be identified that increase the reliability of the analysis. Consequently, it is recommended that mere number crunching is not enough, and that questions of ‘how,’ ‘why,’ and ‘whether’ are required in order to understand the phenomena in their societal settings.

Opinioner och offentligheter online : Vad gör en politisk utsaga framgångsrik? Den användardrivna kommunikationens villkor. Slutrapport
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- ”Vad gör en politisk utsaga framgångsrik? Den användardrivna kommunikationens villkor” är ett ettårigt forskningsprojekt delfinansierat av Internetfonden, Riksbankens Jubileumsfond, Retriever AB, M-Brain AB samt Forsman & Bodenfors AB. Projektledare har varit Jonas Andersson Schwarz, som tillsammans med Johan Hammarlund, Stefan di Grado och Magnus Kjellberg har analyserat data från Twitter och rikspress i syfte att skapa ny kunskap om villkoren för politisk kommunikation i de sociala mediernas tidevarv. Huvudfokus har varit att undersöka vilka specifika faktorer som spelar in för delning av politiska tweets samt vilken typ av material från sociala medier som fångas upp av traditionella nyhetsmedier och vice versa. Samspelet mellan sociala medier och massmedier formar de bilder som görs av sociala medier i samhället, och omvänt: det formar de bilder som görs av massmedia likväl.

Fiske i fjärran vatten : En studie om EU:s fiskeriavtal med utvecklingsländer
- 2016
-
Rapport (refereegranskat)abstract
- Fisheries and fish-related industries comprise an important part of the economic activities in many developing countries. However, many of these countries have limited opportunities to fish outside their coastal zones, since this requires a highly capitalized fleet. A way to utilize national fish resources is to make fisheries agreements whereby foreign fleets pay for the opportunity to fish. For some countries the compensation for fisheries agreements constitutes 30‒50 per cent of the total government budget. In this report the EU’s sustainable partnership agreements with countries in Western Africa, the Pacific and the Indian Ocean are analysed. The purpose is to discuss the positive and negative aspects of the agreements and to identify areas in which the agreements can be improved to contribute better to biological and economic sustainability. (The full text of the report is in Swedish, with an executive summary in English)

Fiske i spåren av Covid-19 - en analys av det svenska yrkesfiskets utveckling och tillgång till stöd
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Pandemin med Covid-19 har slagit hårt mot många branscher. För att mildra skadeverkningarna infördes stödåtgärder i flera länder och så även i Sverige. I den här rapporten presenterar vi en genomgång av effekterna av pandemin för svensk fiskenäring. Vi undersöker också vilka stöd näringen har kunnat söka och i vilken mån stöden passar fiskenäringens struktur.Generellt sett hade svenskt yrkesfiske en relativt god ekonomi före pandemin även om variationerna var stora mellan olika regioner och typer av fiske. Covid-19 har troligtvis haft en liten påverkan på svenskt fiske totalt sett om man tittar på perioden från mars 2020 fram till februari 2021. Men det finns skillnader mellan olika arter och vi ser att vissa arter (havskräfta, räkor och gös) påverkas negativt i början av pandemin.Vi ser att majoriteten av fiskeföretagen (74 %) var registrerade som enskild firma år 2019 och näringen har därför framför allt fått stöd som riktar sig till denna typ av företag, exempelvis det så kallade omsättningsstödet. Många företag tappade en stor andel av omsättningen under pandemin, men stora tapp har även skett historiskt av andra orsaker. Att fisket är säsongsbetonat kan ge problem vid stöd som använder referensperioder som ligger under en annan säsong än den som stödet söks för.Förutom de stöd som kunnat sökas generellt av företag i Sverige har fiskeföretag kunnat söka stöd från den Europeiska havs- och fiskerifonden (EHFF) för tillfälligt upphörande av fiskeverksamhet på grund av Covid 19. Dessa stöd har i stor utsträckning beviljats till fartyg på sydkusten och till fartyg som gått ekonomiskt sämre än genomsnittet redan innan Covid-19.

Fångster av siklöja och priset på löjrom – en ekonomisk analys
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- De senaste åren har Havs- och vattenmyndigheten minskat den mängd siklöja som får fångas i Bottenviken. Minskningen beror på att beståndet av siklöja har minskat. Siklöjan fiskas framförallt för att framställa löjrom. Det innebär att fiskarnas intäkter är starkt beroende av priset på löjrom. Mindre fångster innebär lägre intäkter för fiskarna om inte priset på löjrom samtidigt stiger kraftigt. I denna studie undersöker vi sambandet mellan fångster och priser och finner att priset på löjrom i genomsnitt stiger med mellan 3,7 och 4,6 procent när fångsterna minskar med 10 procent. Priseffekten är stor jämfört med andra svenska fisken och den tycks bli allt större med tiden. Trots detta är den inte tillräckligt stor för att förhindra att minskade fångster leder till lägre intäkter för fisket.

Time for Fishing: Bargaining Power in the Swedish Baltic Cod Fishery
- 2015
-
Ingår i: Marine Resource Economics. - : University of Chicago Press. - 0738-1360 .- 2334-5985. ; 30:3, s. 315-329
-
Tidskriftsartikel (refereegranskat)abstract
- Fishery regulations might not only affect the fleet, but also the relation between fisheries and downstream sectors on the ex-vessel market for fish products. This article estimates the price effects of management reform in the Swedish Baltic Sea cod fishery. In April 2011, as part of a reform process aimed at giving fishers more flexibility, vessels using active gear were given annual non-transferable catch quotas. We examine whether the new management system has altered the bargaining power between fishers and processors in the ex-vessel market for fish. Using a difference-in-differences estimation approach we find that post-reform fishers improve their bargaining power and thus are paid a higher price. However, the price increase is small, amounting to around 2% of the pre-reform price.

Increased blood-brain barrier permeability of morphine in a patient with severe brain lesions as determined by microdialysis
- 2001
-
Ingår i: Acta Anaesthesiologica Scandinavica. - : Wiley. - 0001-5172. ; 45, s. 390-
-
Tidskriftsartikel (refereegranskat)abstract
- Intracerebral microdialysis was utilised to obtain information regarding how morphine is transported across the blood-brain barrier (BBB). In a patient with a severe brain injury, we measured simultaneously unbound extracellular fluid (ECF) concentrations of morphine in human brain and in subcutaneous fat tissue, which were compared to morphine levels in arterial blood. This report shows an increase in morphine levels near the trauma site in the brain compared to uninjured brain tissue. The half-life of morphine in uninjured and injured brain tissue of 178 min and 169 min, respectively, were comparable but were longer than in blood (64 min) and adipose tissue (63 min). This indicates that morphine is retained in brain tissue for a longer time than what could be expected from the blood concentration-time profile. These results show the potential of the microdialysis technique in providing new information regarding the pharmacokinetics of drug in the human brain close to the trauma site and in macroscopically intact tissue.

Blood-brain barrier transport of morphine in patients with severe brain trauma
- 2004
-
Ingår i: British Journal of Clinical Pharmacology. - : Wiley. - 0306-5251 .- 1365-2125. ; 57:4, s. 427-435
-
Tidskriftsartikel (refereegranskat)abstract
- AIMS: In experimental studies, morphine pharmacokinetics is different in the brain compared with other tissues due to the properties of the blood-brain barrier, including action of efflux pumps. It was hypothesized in this clinical study that active efflux of morphine occurs also in human brain, and that brain injury would alter cerebral morphine pharmacokinetics. METHODS: Patients with traumatic brain injury, equipped with one to three microdialysis catheters in the brain and one in abdominal subcutaneous fat for metabolic monitoring, were studied. The cerebral catheter locations were classified as 'better' and 'worse' brain tissue, referring to the degree of injury. Morphine (10 mg) was infused intravenously over a 10-min period in seven patients in the intensive care setting. Tissue and plasma morphine concentrations were obtained during the subsequent 3-h period with microdialysis and regular blood sampling. RESULTS: The area under the concentration-time curve (AUC) ratio of unbound morphine in brain tissue to plasma was 0.64 (95% confidence interval 0.40, 0.87) in 'better' brain tissue (P < 0.05 vs. the subcutaneous fat/plasma ratio), 0.78 (0.49, 1.07) in 'worse' brain tissue and 1.00 (0.86, 1.13) in subcutaneous fat. The terminal half-life and T(max) were longer in the brain vs. plasma and fat, respectively. The relative recovery for morphine was higher in 'better' than in 'worse' brain tissue. The T(max) value tended to be shorter in 'worse' brain tissue. CONCLUSIONS: The unbound AUC ratio below unity in the 'better' human brain tissue demonstrates an active efflux of morphine across the blood-brain barrier. The 'worse' brain tissue shows a decrease in relative recovery for morphine and in some cases also an increase in permeability for morphine over the blood-brain barrier.

Tidskriftsartikel (refereegranskat)abstract
- The Old Wood in a New Light database project focuses on the digitization and accessibility of the results of dendrochronological samples analyzed and archived at four Swedish university-based tree-ring laboratories at Lund University, Stockholm University, University of Gothenburg, and the Swedish University of Agricultural Sciences. Collaboration with the Environmental Archaeology Laboratory and Humlab at Umeå University enables long-term open access to data, raw data, and metadata. In this project, we (1) systematically undertake large-scale entry and open access publication of results from wood samples scientifically analyzed and archived by Swedish laboratories and the associated metadata, into the Strategic Environmental Archaeology Database (SEAD; www.sead.se) research data infrastructure, and (2) actively promote the database as a resource for new and ongoing interdisciplinary research initiatives. Including dendrochronological data in SEAD infrastructure allows interdisciplinary studies that combine major scientific and societal questions. Building on a pilot study of construction timber from southern Sweden and adaptation of SEAD digitization workflows, more than 70 000 samples archived at the four dendrochronological laboratories are now being handled in the project. The broad coverage of research networks, stakeholder interaction, and strategic support from the cultural heritage community is guaranteed owing to the ongoing collaboration between laboratories and an established international and multidisciplinary reference group.

Direct nose-to-brain transfer of morphine after nasal administration to rats
- 2006
-

-
Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: The aim of this study was to quantify the olfactory transfer of morphine to the brain hemispheres by comparing brain tissue and plasma morphine levels after nasal administration with those after intravenous administration. METHODS: Morphine (1.0 mg/kg body weight) was administered via the right nostril or intravenously as a 15-min constant-rate infusion to male rats. The content of morphine and its metabolite morphine-3-glucuronide in samples of the olfactory bulbs, brain hemispheres, and plasma was assessed using high-performance liquid chromatography, and the areas under the concentration-time curves (AUC) were calculated. RESULTS: At both 5 and 15 min after administration, brain hemisphere morphine concentrations after nasal administration were similar to those after i.v. administration of the same dose, despite lower plasma concentrations after nasal administration. The brain hemispheres/plasma morphine AUC ratios for the 0-5 min period were thus approximately 3 and 0.1 after nasal and i.v. administration, respectively, demonstrating a statistically significant early distribution advantage of morphine to the brain hemispheres via the nasal route. CONCLUSION: Morphine is transferred via olfactory pathways to the brain hemispheres, and drug transfer via this route significantly contributes to the early high brain concentrations after nasal administration to rats.

Historielärares klassrumsbedömningar : Innehåll och roll i ett historiedidaktiskt perspektiv
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Assessment is a permanent part of history teaching, and the interest in assessment is highly current in the Swedish educational system. One aspect is formative assessment and feedback as a tool for learning; another aspect is that assessment tends to be more and more formalized.Earlier research on written assignments and tests show that history teachers often focus on assessing history knowledge as content and memorizing school textbook. Thus the risk is that history education and assessment does not correspond to the new curricula and rating scale with a wider range of goals.This study investigates the ongoing assessment in the history classroom, frequently entitled ”the black box”. Four history teachers in Swedish upper secondary school were interviewed about assessment, and their classroom assessments in a series of lessons were observed and recorded. The requested historical competencies in teachers´ questioning and feedback are interpreted through the concepts of the historical thinking tradition. Similarities and differences are discussed.Results show a great variety in questioning and feedback. Closed questions are present, but are not in majority, and encouraging feedback is more frequent than rejective. All teachers have the same principle – first order concepts or content come first, then second order concepts or thinking about the first order concepts. Among the second order concepts comparision stands as a universal tool to understand content and handle second order concepts. Cause and consequence combined with continuity and change (most focus on change) also appear to be common in the classroom assessements. More rare are historical persectives and significance. Most teachers consider the classroom assessment as valuable chances to get to know pupils´ history knowledge, but one teacher consider the ongoing pupils’ statements as far more reliable than the written ones, when it comes to grading.The over all result indicates that classroom assessments can involve more than history knowledge as memorized content like single facts.

Hummerfiske på västkusten - mer lönsamt med färre yrkesfiskare?
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Nuvarande förvaltning av det svenska hummerfisket riskerar att leda till överfiske och dålig lönsamhet för yrkesfisket. Kan den samhällsekonomiska nyttan av det yrkesmässiga hummerfisket öka genom att begränsa tillträdet till ett färre antal yrkesfiskare?Vår slutsats är att en sådan åtgärd riskerar att få begränsad effekt på grund av teknisk utveckling i fisket och ett stort intresse för fritidsfiske. Att begränsa antalet yrkesfiskare kan också få negativa ekonomiska konsekvenser för fiskare som inte får tillträde. Vi finner emellertid att en stor del av det yrkesmässiga hummerfisket bedrivs av personer som inte har detta fiske som en huvudsaklig del av sin försörjning.

Intäkter för svenska kräftfiskare på västkusten
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Havskräfta är en viktig art för svenskt fiske. Kräftan fångas antingen med bur eller med trål i Kattegatt och Skagerrak. På uppdrag av Havs- och vattenmyndigheten analyseras yrkesfiskets intäkter och fartygens landningsmönster för att ge underlag till en bedömning av effekterna av att minska utrymmet för trålfiske och öka utrymmet för burfiske.Analysen visar att trålfisket generellt sett är mindre beroende av havskräfta än burfisket, men att det finns ett antal fiskare, framför allt de med mindre trålfartyg, som får stora delar av sina intäkter från de aktuella områdena. Förändrade områden för fisket påverkar inte bara fördelningen mellan trål- och burfiske, utan kan också förändra var landningarna av havskräfta sker. Vissa landningshamnar har idag stora landningar av trålfiskad kräfta men endast marginella landningar av burfångad.

Local markets and price premiums—The case of the establishment of the Stockholm fish auction
- 2021
-
Ingår i: Fisheries Research. - : Elsevier BV. - 0165-7836 .- 1872-6763. ; 236
-
Tidskriftsartikel (refereegranskat)abstract
- The promotion of locally produced food has been a growing marketing trend in recent years. Locally produced food is associated with positive values such as environmental benefits, fresher and safer products as well as contributing to building closer ties between people in local communities. We use a case study were a local fish auction was established in the Stockholm area in Sweden with the aim to supply the local market with fish, mainly pikeperch, from the region. Using monthly prices we investigate if the establishment of the auction has resulted in a price premium and separate markets for locally caught pikeperch. Our results show that there is no price premium and that the Stockholm market is not decoupled from the national market after the establishment of the new auction. In fact, the Swedish market appears to become more integrated and non-auction buyers of pikeperch have to pay more to fishers after the establishment of the auction.

- Knowledge of price formation in fisheries is important in understanding effects of fisheries regulations and the support or resistance to regulations from different stakeholders. This article studies how demand can be traced out using wind speed on a fishing trip. Wind speed is strongly correlated with the quantities of Norwegian lobster (Nephrops) available on the market. Using wind variables as instrumental variables and data on daily average prices and quantities over a 20-year period, we estimate the daily aggregate demand for two varieties of Nephrops.Wefind that the demand for both varieties is highly responsive to price changes and that own-price elasticities using the instrumental variable estimators are two to three times higher than ordinary least squares (OLS) estimates suggest. In addition, cross-price elasticities show, in contrast to OLS results, that the two types of Nephrops are close substitutes.

Ökat fiske efter havskräfta - med risk för lägre priser?
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den mängd havskräfta som säljs på den svenska marknaden är idag långt mindre än den tillgängliga kvoten. Skulle fiskarna få möjlighet att sälja mer havskräftor ökar intäkterna, men det kan också leda till att priserna blir lägre. I den här studien analyserar vi hur priserna påverkas om mer trålfiskad havskräfta säljs på marknaden. Resultaten visar att:Om mängden trålfiskad havskräfta ökar med 5 procent minskar priset med 1 procent, dvs. försäljningsvolymen måste öka mycket för att priset ska falla.Ett lägre pris på trålfångad havskräfta gör att konsumenter köper mer trålfångad och mindre burfångad havskräfta.Mindre efterfrågan på burfångad havskräfta innebär att burfisket förlorar intäkter.

- As a pervasive historical construct that is both foreign and familiar, the USA has a looming presence in Swedish media discourse. Swedish journalists’ views of the USA can best be described as ambivalent — critical of a unilateral or too passive US foreign policy, while at the same time being heavily influenced by many aspects of the American economic model and culture. This article presents the results of an analysis of Swedish editorials, debate, commentary and cultural articles about the USA in time periods between 1984 and 2009. During these three decades USA actions are broadly framed against the backdrop of Cold War, globalization and cultural contestation paradigms respectively. The USA is seen as a formidable power, one that should be checked by others on the international stage. Cultural symbols based on historical European narratives about the US are called upon to illustrate reckless unilateralism (‘Space Cowboy’ Reagan) or the future-oriented entrepreneur as a role model for Sweden (during the Clinton years). The final decade under the cultural contestation paradigm is also ambivalent — the role of religion in the USA appears foreign to Swedish eyes, whereas the USA’s cultural misunderstandings with others appear familiar.

Variations in the isotopic composition of molybdenum in freshwater lake systems

Tidskriftsartikel (refereegranskat)abstract
- Variations in molybdenum isotopic composition, spanning the range of ≈ 2.3‰ in the terms of 97Mo/95Mo ratio, have been measured in sediment cores from three lakes in northern Sweden and north-western Russia. These variations have been produced by both isotopically variable input of Mo into the lakes due to Mo isotopic heterogeneity of bedrock in the drainage basins and fractionation in the lake systems due to temporal variations in limnological conditions. Mo isotope abundances of bedrock in the lake drainage basins have been documented by analysis of Mo isotope ratios of a suite of molybdenite occurrences collected in the studied area and of detrital fractions of the lake sediment cores. The median δ97Mo value of the investigated molybdenites is 0.26‰ with standard deviation of 0.43‰ (n = 19), whereas the median δ97Mo value of detrital sediment fractions from two lakes is - 0.40‰ with standard deviation of 0.36‰ (n = 15). The isotopic composition of Mo in the sediment cores has been found to be dependent on redox conditions of the water columns and the dominant type of scavenging phases. Hydrous Fe oxides have been shown to be an efficient scavenger of Mo from porewater under oxic conditions. Oxidative precipitation of Fe(II) in the sediments resulted in co-precipitation of Mo and significant authigenic enrichment at the redox boundary. In spite of a pronounced increase in Mo concentration associated with Fe oxides at the redox boundary the isotopic composition of Mo in this zone varies insignificantly, suggesting little or no isotope fractionation during scavenging of Mo by hydrous Fe oxides. In a lake with anoxic bottom water a chironomid-inferred reconstruction of O2 conditions in the bottom water through the Holocene indicates that increased O2 concentrations are generally associated with low δ97Mo/95Mo values of the sediments, whereas lowered O2 contents of the bottom water are accompanied by relatively high δ97Mo/95Mo values, thus confirming the potential of Mo isotope data to be a proxy for redox conditions of overlying waters. However, it is pointed out that other processes including input of isotopically heterogeneous Mo and Mn cycling in the redox-stratified water column can be a primary cause of variations in Mo isotopic compositions of lake sediments.

Historia på högstadiet : Historiekulturella yttringar i och utanför ett klassrum i Sverige hösten 2009
- 2019

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- How do students use schools´ history education to develop their historical consciousness? In which ways could history education be regarded as a historical-culture expression, i.e. as a part of a society’s interest in the past? This thesis takes its point of departure in these overarching questions. More specifically the research was carried out as a contextualised case study of sixteen history lessons in a Swedish Year 9 class, in the autumn of 2009. The contextualisation consists of an analysis on historical-culture expressions in Sweden at that time. Despite conflicting opinions, the major finding was the common view of Sweden as a country that solves her problems in a peaceful way, both in the past, the present and the future. The classroom study was conducted with an ethnographical approach with close attention to teacher-student interactions. The research was guided by an analytical model inspired by the historian Jörn Rüsen’s theories on history learning processes.The results show in detail the complicated learning processes in the classroom but also the connection with the historical-culture expressions in Sweden at that moment. One major finding was the tendency to react to the rise of contemporary islamophobia and nationalism in Sweden by making comparisons with the development in Weimar Germany in the beginning of the 1930s. This tendency was present both in and outside the classroom.

- BACKGROUND: Impaired metabolism of morphine may lead to an increase in sedation and respiratory depression. METHODS: In the present study we investigated morphine pharmacokinetics in patients who had undergone liver resection (n = 15) compared to a control group undergoing colon resection (n = 15). Morphine was administered IV by patient-controlled analgesia. Plasma concentrations of morphine, morphine-6-glucuronide, and morphine-3-glucuronide were measured 2-3 times daily for the first two postoperative days. Pain intensity scores were assessed three times daily and respiratory rate and sedation scores every third hour. RESULTS: There were no differences in morphine requirements 1.1 (0.8-2.5 [median, interquartile range]) mg/h (liver resection) and 1.5 (1.1-1.7) mg/h (colon resection) [P = 0.84]) or in pain intensity scores (P > 0.3) between the groups. Plasma morphine concentrations were higher in patients undergoing liver resection than in the control group (P < 0.01) reflecting a lower rate of morphine metabolism. Plasma morphine concentrations were correlated with the volume of liver resection (P < 0.02). However, plasma concentrations of morphine-6-glucuronide and morphine-3-glucuronide did not differ between the groups (P = 0.62 and P = 0.48, respectively). There was a higher incidence of sedation (P = 0.02), but not respiratory depression (P = 0.48), after liver resection. CONCLUSION: The study demonstrates that plasma concentrations of morphine are higher in patients undergoing liver resection compared with patients undergoing colon resection. Sedation scores were higher in patients undergoing liver resection. Caution is therefore recommended when administering morphine to this patient group.
