- The Tundra Ecology -94 expedition investigated inflow of inorganic and organic carbon to the shelf seas by river runoff, and its transformation by biochemical processes in seawater and sediment. In addition, anthropogenic radionuclides, 137Cs, 90Sr, and 239,240Pu, were studied in water and sediments. The distribution of dissolved inorganic carbon indicates that the majority of the Ob and Yenisey discharges flow into the Laptev Sea before entering the central Arctic Ocean. The sediment study shows that there is a marked difference in benthic oxygen uptake, efflux of dissolved inorganic carbon and nutrients between localities. 137Cs activity from the Chernobyl accident is 30% in the Barents, Kara, and Laptev Seas. 137Cs increased from 5-8 Bq m-3 in Barents Sea, 5-13 Bq m-3 in the Kara Sea to 8-15 Bq m-3 in the Laptev Sea, but with locally low concentrations at the river mouths. Corresponding values for 90Sr were 2.5, 3, and 4 Bq m-3, respectively.

- A series of eight peptides corresponding to the amino acid sequence of the hinge region of IgG and 17 newly synthesized peptide analogues containing a piperidine moiety as a replacement of a glycine residue were tested as potential inhibitors of the bacterial IgG degrading enzyme of Streptococcus pyogenes, IdeS. None of the peptides showed any inhibitory activity of IdeS, but several piperidine-based analogues were identified as inhibitors. Two different analysis methods were used: an SDS-PAGE based assay to detect IgG cleavage products and a surface plasmon resonance spectroscopy based assay to quantify the degree of inhibition. To investigate the selectivity of the inhibitors for IdeS, all compounds were screened against two other related cysteine proteases (SpeB and papain). The selectivity results show that larger analogues that are active inhibitors of IdeS are even more potent as inhibitors of papain, whereas smaller analogues that are active inhibitors of IdeS inhibit neither SpeB nor papain. Two compounds were identified that exhibit high selectivity against IdeS and will be used for further studies.

Are values related to culture, identity, community cohesion and sense of place the values most vulnerable to climate change?
- 2019
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 14:1
-
Tidskriftsartikel (refereegranskat)abstract
- Values related to culture, identity, community cohesion and sense of place have sometimes been downplayed in the climate change discourse. However, they have been suggested to be not only important to citizens but the values most vulnerable to climate change. Here we test four empirical consequences of the suggestion: (i) at least 50% of the locations citizens' consider to be the most important locations in their municipality are chosen because they represent these values, (ii) locations representing these values have a high probability of being damaged by climate change induced sea level rise, (iii) citizens for which these values are particularly strongly held less strongly believe in the local effects of climate change, and (iv) citizens for which these values are particularly strongly held less strongly believe that they have experienced the effects of climate change. The tests were made using survey data collected in 2014 from 326 citizens owning property in Höganäs municipality, Sweden, and included values elicited using a new methodology separating instrumental values from end values, and using the former (which strictly speaking should be seen as estimates of usefulness rather than as aims in themselves) as stepping stones to pinpoint the latter, that represent the true interests of the respondents. The results provide the first evidence that, albeit frequent, values related to culture, identity, community cohesion and sense of place are not the values most vulnerable to climate change. This in turn indicates a need to further investigate the vulnerability of these values to climate change, using a methodology that clearly distinguishes between instrumental and end values.

DeveLoP—A Rationale and Toolbox for Democratic Landscape Planning
- 2021
-
Ingår i: Sustainability (Switzerland). - : MDPI AG. - 2071-1050. ; 13:21
-
Tidskriftsartikel (refereegranskat)abstract
- A rationale for an individuals-oriented landscape approach to sustainable land-use planning based on an analysis of bio-geo-physical components as well as the human components of the landscape is presented. A toolbox for analysing individuals’ decision-making and valuations in the landscape is described. The toolbox can provide evidence on the drivers of individuals’ decision-making in the landscape and the decision strategies they apply. This evidence can be used to identify communication needs and to design guidelines for effective communication. The tool for value elicitation separates the instrumental values (means) and end values (goals) of individuals with respect to locations in the landscape. This distinction, and knowledge of the end values in the landscape, are critical for the achievement of policy goals and for spatial planning from a democratic point of view. The individuals-oriented landscape approach has roots in geography and draws on behavioural decision research together with a model for integrating “science and proven experience” that is widely used in public decision-making in the Nordic countries. The approach differs from other scholarly disciplines addressing sustainable land-use planning. It is suitable for application on decision-making problems that include trade-offs between values. An overview of empirical studies is provided in which the individuals-oriented landscape rationale is applied to climate change.

Forest Owners' Response to Climate Change : University Education Trumps Value Profile
- 2016
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 11:5
-
Tidskriftsartikel (refereegranskat)abstract
- Do forest owners’ levels of education or value profiles explain their responses to climate change? The cultural cognition thesis (CCT) has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is greatest, and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile.

Bokkapitel (refereegranskat)abstract
- Wind damage to forests can be divided into (1) the direct damage done to the forest and (2) indirect effects. Indirect effects may be of different kinds and may affect the environ- ment as well as society. For example, falling trees can lead to power and telecommunica- tion failures or blocking of roads. The salvage harvest of fallen trees is another example and one that involves extremely dangerous work. In this overview we provide examples of different entities, services, and activities that may be affected by wind damage to for- ests. We illustrate how valuation of the damage depends on the perspective applied and how the affected entities, services, and activities may represent different types of values. Finally we suggest means for how to actively manage the risk in an ethically sustaina- ble way. Many of our examples will be drawn from the experiences of the wind damage Gudrun in southern Sweden on 8–9 January 2005. The direct as well as indirect effects, which are described, are by no means unique to the Gudrun wind damage event and similar or even worse effects have been described after the wind damage events Martin and Lothar in 1999, and Klaus in 2009.

Understanding risk in forest ecosystem services: implications for effective risk management, communication and planning
- 2014
-
Ingår i: Forestry. - : Oxford University Press (OUP). - 0015-752X .- 1464-3626. ; 87, s. 219-228
-
Tidskriftsartikel (refereegranskat)abstract
- Uncertainty, insufficient information or information of poor quality, limited cognitive capacity and time, along with value conflicts and ethical considerations, are all aspects that make risk management and risk communication difficult. This paper provides a review of different risk concepts and describes how these influence risk management, communication and planning in relation to forest ecosystem services. Based on the review and results of empirical studies, we suggest that personal assessment of risk is decisive in the management of forest ecosystem services. The results are used together with a review of different principles of the distribution of risk to propose an approach to risk communication that is effective as well as ethically sound. Knowledge of heuristics and mutual information on both beliefs and desires are important in the proposed risk communication approach. Such knowledge provides an opportunity for relevant information exchange, so that gaps in personal knowledge maps can be filled in and effective risk communication can be promoted.

Strategies in health-promoting dialogues: primary healthcare nurses' perspectives : a qualitative study
- 2014
-
Ingår i: Scandinavian Journal of Caring Sciences. - : John Wiley & Sons. - 0283-9318 .- 1471-6712. ; 28:2, s. 235-244
-
Tidskriftsartikel (refereegranskat)abstract
- Aim and objectives The aim of this study was to describe dialogic strategies about health and lifestyle used by primary healthcare nurses (PHNs) in the Vasterbotten Intervention Programme (VIP) in Sweden.Background The VIP offers all citizens aged 40, 50 and 60 in Vasterbotten County an individual health check-up followed by a health-promoting dialogue with a specialist PHN. Inconsistencies in previous reports of the effects of lifestyle counselling and health promotion suggest that it is important to study dialogues about health and lifestyle to understand health-promoting strategies and to highlight aspects important to improving their effects.Method In 2010, we conducted in-depth interviews with ten experienced PHNs working with the VIP at eight healthcare centres in Vasterbotten County, Sweden. Qualitative content analysis was used to illuminate the nurses' strategies in health-promoting dialogues. The Regional Ethics Board (Dno 06-126M) approved the study.Results The PHNs used various strategies in dialogues about health and lifestyle that fell under the five themes 'Guiding patients vs. pressuring them; Adjusting to patients vs. directing the conversation; Inspiring confidence vs. instilling fear; Motivating and supporting patients vs. demanding responsibility; and lastly, Introducing emotionally charged subjects or avoiding them'.Conclusions The results of this study may add knowledge about the difficulties and opportunities in health counselling. In the discussion, we suggest professional reflection as a means to increase knowledge and awareness about the self and context in the process of health counselling.

Spatial or narrative: a study of the Agneta and Frida system
- 1999. - 1
-
Konferensbidrag (refereegranskat)abstract
- We propose that analysing interviews with subjects who have been exposed to anthropomorphic characters from a metaphorical point of view can provide insights into how characters in the interface are perceived. In a study of the Agneta & Frida system (two characters that comment contents of web pages in an ironic, humorous manner) we found that subjects who used Agneta & Frida used more narrative verbs and adverbs than users who only browsed the web pages. In the latter case, more spatial verbs and adverbs were used. This may imply that normal web browsing is perceived as navigation through a space, while Agneta & Frida provides for a more narrative experience.

Challenges and opportunities to advance manufacturing research for sustainable battery life cycles
- 2024
-
Ingår i: Frontiers in Manufacturing Technology. - 2813-0359. ; 4
-
Tidskriftsartikel (refereegranskat)abstract
- Advanced manufacturing research for sustainable battery life cycles is of utmost importance to reach net zero carbon emissions (European Commission, 2023a) as well as several of the United Nations Sustainable Development Goals (UNSDGs), for example: 30% reduction of CO2 emission, 10 million job opportunities and access to electricity for 600 million people (World Economic Forum, 2019). This editorial paper highlights international motivations for pursuing more sustainable manufacturing practices and discusses key research topics in battery manufacturing. Batteries will be central to our sustainable future as generation and storage become key components to on-demand energy supply. Four underlying themes are identified to address industrial needs in this field: 1. Digitalizing and automating production capabilities: data-driven solutions for production quality, smart maintenance, automation, and human factors, 2. Human-centric production: extended reality for operator support and skills development, 3. Circular battery life cycles: circular battery systems supported by service-based and other novel business models, 4. Future topics for battery value chains: increased industrial resilience and transparency with digital product passports, and next-generation battery chemistries. Challenges and opportunities along these themes are highlighted for transforming battery value chains through circularity and more sustainable production, with a particular emphasis on lithium-ion batteries (LIB). The paper concludes with directions for further research to advance a circular and sustainable battery value chain through utilizing the full potential of digitalization realising a cleaner, more energy-efficient society.

Handbook for increased recovery of urban excess heat
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this book is to consolidate information from low temperature waste heat recovery demonstration sites. Apart from technical validation, the ReUseHeat project has generated knowledge about the urban waste heat potential in Europe, main stakeholders and different business aspects. Five stakeholder groups are targeted. These are urban waste heat owners, District Heating (DH) companies, policy makers, investors and customers. In the first chapter of the book, the concept of urban waste heat is introduced and the urban waste heat potential in Europe is presented. Thereafter (chapter two), information on business aspects is provided (stakeholders, value chain, risks, contracts and business model characteristics). Chapter three showcases the demonstrator concepts (waste heat recovery from data centre, hospital, metro and awareness creation about urban waste heat recovery) and performance data. Throughout the writing of the handbook, it was identified that it is important to compare the cost of different heating alternatives, to facilitate customer decision making. Therefore, a model was derived to compare costs of heating alternatives. It is presented in chapter four. Urban waste heat recovery is news. It is therefore important that stakeholders are made aware of the possibility to use the locally available heat and to start collaborating in new ways. To ensure as much stakeholder engagement as possible, the writing process of this book encompassed a six-month stakeholder involvement process. The stakeholder input is presented in chapter five. In chapter six, thoughts on the future development of district energy, policy implications and major learnings from the project are presented. This book was written within the ReUseHeat project. The work on the book was initiated after the first out of five years of activity to ensure that the consortium would be engaged in its development and to capture the knowledge generated on an ongoing basis. The final version of the book was ready and placed on the ReUseHeat webpage in September 2022. The project webpage remains in operation until 2024. The book not only exists in digital format. 600 copies were also printed and distributed to relevant stakeholders. All partners of the consortium have contributed to the writing of the book.

Tidskriftsartikel (refereegranskat)abstract
- Background father's sense of security in the early postnatal period is important for the whole family. An instrument, which measures Parents' Postnatal Sense of Security (the PPSS instrument), is under development.Objective to explore and describe factors, which influence fathers' sense of security during the first postnatal week.Methods an explorative design with a qualitative approach was used. Thirteen fathers from three hospital uptake areas in Southern Sweden were interviewed using focus group discussions and individual interviews. Analysis was carried out using qualitative content analysis.Findings participation in the processes of pregnancy birth and early parenthood emerged as the main category for fathers' postnatal sense of security. The emergent categories were; ‘willingness to participate and take responsibility’, ‘being given the opportunity to take responsibility’, ‘being assured about mother's and baby's well-being’, ‘having someone to turn to—knowing who to ask’, ‘being met as an individual’ and ‘being met by competent and supporting staff’.Key conclusions and implications for practice new and specific items of importance when investigating fathers' sense of security during the early postnatal period have been pinpointed. Fathers' sense of early postnatal security may be enhanced by giving them a genuine opportunity to participate in the whole process and by giving them the opportunity to stay overnight at the hospital after the birth. Midwives and care organisations need to give clear information about where competent help and advice can be obtained at all hours. Midwives should strengthen the fathering role by acknowledging and listening to the father as an individual person.

Tidskriftsartikel (refereegranskat)abstract
- Accelerator mass spectrometry (AMS) is an ultra-sensitive method for counting atoms, both radionuclides and stable nuclides. When using small tandem accelerators to measure heavy isotopes, interfering isobars are often troublesome. One way to reduce this interference is to combine AMS with the detection of characteristic X-rays of the projectile. After analysis in the AMS system it is possible to identify ions of different atomic number by their characteristic X-rays, by slowing down the ions in a suitable target. In this paper, the detection limit of Ni-59 at the Land AMS facility is reported. A method for the chemical extraction of nickel from stainless steel, combined with a purification step to reduce the cobalt content in the sample by several orders of magnitude, is also described.

Tidskriftsartikel (refereegranskat)abstract
- Antibody-based proteomics provides a powerful approach for the functional study of the human proteome involving the systematic generation of protein-specific affinity reagents. We used this strategy to construct a comprehensive, antibody-based protein atlas for expression and localization profiles in 48 normal human tissues and 20 different cancers. Here we report a new publicly available database containing, in the first version, similar to 400,000 high resolution images corresponding to more than 700 antibodies toward human proteins. Each image has been annotated by a certified pathologist to provide a knowledge base for functional studies and to allow queries about protein profiles in normal and disease tissues. Our results suggest it should be possible to extend this analysis to the majority of all human proteins thus providing a valuable tool for medical and biological research.

Tillgänglighet, närhet och synlighet – gemensamma utmaningar för LUB-nätverket för att möta forskares behov av stöd vid Lunds universitet
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report presents a project at Lund University Libraries (LUB) during the fall of 2012, with the object to identify areas where the present research support services ought to be developed and strengthened. The project is three folded and contains a) a literature review focusing on definitions and examples of research support services as well as researchers’ needs and experiences of support services, b) a survey to get an overview of the support services offered today at LUB, the decentralized library network at Lund University, and c) focus group interviews with researchers, one group from each partaking faculty, to investigate key obstacles in their research processes. In all three parts a model of the research process schematically divided into four phases was applied; to start a project, to collect material, to process/analyze/write and to communicate the results. The first two stages of the project, the literature overview and the survey, form a background and both show that many support services are concentrated around the phases to collect material and to communicate results. The findings from the focus group interviews point to common needs and issues as well as special needs and issues related to different ways of doing and communicating research. Common for most researchers is limited time, a need for funding and an everyday fragmentation. They talk about the importance of networks, their efforts to navigate in an abundance of material and ways to find it and a need for overviews and help to understand new ways and demands to communicate. Most concern is expressed in the phases to start a project, to collect material and to communicate results. A major conclusion is that the research support services need to be available, visible and in close proximity to the researchers. Further, the development of support services needs to take into consideration both common traits as well as local variations in research practices. Therefore, discussions concerning LUB as a whole, need to be related to discussions at the single faculty libraries. Apart from knowledge about how to address the research support services at LUB, the project generates a model for how librarians can understand the research community that they are working with and with whom to create networks and partnerships for the future.

Tidskriftsartikel (refereegranskat)abstract
- In 1995, a disease control and intervention project was initiated in Malmöhus county in southern Sweden to limit the spread of penicillin-resistant pneumococci. Since most of the carriers of pneumococci are preschool children, and since most of the spread is believed to take place in day-care, a mathematical model, in the form of a stochastic process, for the spread in a day-care group was constructed. Effects of seasonal variation and size of the day-care group were particularly considered. The model was then used for comparing results from computer simulations without and with intervention. Results indicate that intervention is highly effective in day-care groups with more than ten children during the second half of the year.

An ATR-FTIR spectroscopic study of the competitive adsorption between oxalate and malonate at the water-goethite interface.
- 2006
-
Ingår i: Journal of Colloid and Interface Science. - : Elsevier BV. - 0021-9797. ; 294:1, s. 31-7
-
Tidskriftsartikel (refereegranskat)abstract
- The competitive adsorption between oxalate and malonate at the water-goethite interface was studied as a function of pH and total ligand concentrations by means of quantitative adsorption measurements and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy. The results obtained show that ATR-FTIR spectroscopy resolves the individual spectroscopic features of oxalate and malonate when adsorbed simultaneously at the water-goethite interface. The characteristic peaks of all four types of predominating surface complexes existing in the single ligand systems were identified, namely one inner sphere and one outer sphere surface complex for each ligand. The quantitative adsorption data showed that oxalate partially out-competes malonate at the water-goethite interface. Evaluation of the peak area variations as a function of pH indicated that the stronger oxalate adsorption can be ascribed to the more stable inner sphere surface complex of oxalate, which in turn is related to the oxalate five-member chelate ring structure yielding a more stable complex compared to the six-member ring of malonate.

Time-dependent surface speciation of oxalate at the water-boehmite (γ-AlOOH) interface: implications for dissolution
- 2001
-
Ingår i: Geochimica et Cosmochimica Acta. ; 65:24, s. 4481-92
-
Tidskriftsartikel (refereegranskat)abstract
- The surface speciation of oxalate at the water-boehmite (γ-AlOOH) interface during adsorption and dissolution reactions was studied by means of attenuated total reflectance infrared spectroscopy. The structural interpretations of infrared (IR) data were based on comparison with results from theoretical frequency calculations. Two different surface complexes were identified: an inner-sphere complex with a bidentate five-membered chelate structure involving both carboxylate groups; and a hydrogen-bonded surface complex with no direct bonding to Al atoms. A scheme was developed by which the surface concentrations of these complexes could be determined from IR spectroscopy data. The concentration of the hydrogen bonded complex was shown to be strongly dependent on the experimental conditions, and the concentration of the inner-sphere complex was comparatively insensitive to the conditions within the studied experimental range. The dissolution data indicated that an excess of oxalate with respect to a critical surface concentration of oxalate was necessary to induce significant boehmite dissolution. Under dissolving conditions, the concentration of the inner-sphere complex was shown to be almost identical to this critical concentration and thus a stable entity.

Nationellt fackspråk för vård och omsorg : Slutrapport
- 2011
-
Rapport (populärvet., debatt m.m.)abstract
- SammanfattningEtt tillgängligt och använt nationellt fackspråk ska bidra till en god och säker vård och omsorg. Det ska även medverka till att kvaliteten och resultaten på området ska kunna följas upp och jämföras på ett mer effektivt sätt. Slutrapporten presenterar resultatet av projektet Nationellt fackspråk för vård och omsorg samt förslag till förvaltning och utveckling.ResultatetResultatet innefattar bland annat att det internationella begreppssystemet Snomed CT är översatt till svenska och att det är förberett för förvaltning och distribution. Socialstyrelsen har även tagit fram och testat metoder för förvaltning och utveckling av det nationella fackspråket i sin helhet. Därtill har representanter för målgrupperna informerats och fått kunskap.Rapporten innehåller en utförlig beskrivning av det nationella fackspråkets sammantagna innehåll: Socialstyrelsens termbank, klassifikationer och kodverk, den svenska versionen av Snomed CT, metoder för utveckling och förvaltning samt regler för användning.Förvaltning, införande och resursbehovI rapporten finns förslag till hur hela det nationella fackspråket kan tas omhand av Socialstyrelsen och hur det kan införas i vården och omsorgen. Projektets övergång till en långsiktigt hållbar organisation kräver resurser. Därför redogör rapporten för det förväntade resursbehovet för förvaltning och utveckling. Bland annat föreslås en treårig utbildningsinsats samt stimulansbidrag för införande.Krav på styrning, samordning och förtydligat ansvarRapporten betonar behovet av en samlad och medveten styrning av utvecklingen inom området. Socialstyrelsen vill ha en samordnande roll i utvecklingen och förvaltningen av det nationella fackspråket.

- The Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS), a self-rating questionnaire, was designed to measure symptoms and the effect of treatment in patients suffering from irritable bowel syndrome. The aim of this descriptive correlational study was to conduct further psychometric validation after the VAS-IBS had been used in clinical practice, translate it into English, and compare the results with controls. Forty-nine patients with irritable bowel syndrome (median age = 38 years old [range, 18-69 years]) were compared with 90 healthy persons (median age = 44 years old [range, 21-77 years]) who served as controls. The patients with irritable bowel syndrome completed 3 questionnaires: the VAS-IBS, the Gastrointestinal Symptom Rating Scale, and the Perception of Change of Symptoms. Controls completed only the VAS-IBS. Results showed that the VAS-IBS is a valid questionnaire that measures the degree of change of symptoms and discriminates between patients who have irritable bowel syndrome from those who do not. It is important to compare the VAS-IBS among different cultural populations so we suggest that the English version of the VAS-IBS should now be used in English-speaking countries and be further tested for validity and reliability with English-speaking patients.

Avräkningsmetoden : En skatterättslig studie om undvikande av internationell dubbelbeskattning
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The territorial scope of modern income tax systems frequently leads to the occurrence of international double taxation, i.e., that the same income is taxed in two or more states. In cases of international double taxation, a foreign tax credit may be given by applying either the method article in Swedish tax treaties or the unilateral Foreign Tax Credit Act. The foreign tax credit method seeks to eliminate double taxation or, in other words, to achieve single taxation. In principle, the taxpayer’s residence state has the responsibility to credit foreign taxes which have been imposed because the income source is located abroad.The overall aim of this thesis is to study the Swedish foreign tax credit method in order to arrive at an understanding of the method as a whole. To achieve this aim, a question is posed, namely ”which concept of double taxation characterizes the foreign tax credit method?” The thesis is divided into three parts. The first part contains a reading of the historical and conceptual background of the phenomenon of international double taxation and the foreign tax credit method. It also consists of a study of the general systematic and territorial aspects of the foreign tax credit method. The second part deals with how to identify such international double taxation which the foreign tax credit method is aimed at eliminating. The third part concerns how the foreign tax credit method seeks to achieve single taxation in a situation where international double taxation has been identified. The last two parts corresponds to the two essential elements of the foreign tax credit method.When interpreting the foreign tax credit method, the concept of double taxation is related to fundamental concepts of modern income tax law, such as tax subject, tax object, and income tax. The classical concept of international double taxation has some relevance for the Swedish foreign tax credit method, although distinctive features of the Swedish tax system require special considerations. Regarding the second essential element of the foreign tax credit method, the achievement of single taxation, an important aspect is also to consider how different ways of eliminating double taxation affect the relationship between the residence state and the source state.

- The evolution of reading frame maintenance must have been an early event, and presumably preceded the emergence of the three domains Archaea, Bacteria and Eukarya. Features evolved early in reading frame maintenance may still exist in present-day organisms. We show that one such feature may be the modified nucleoside 1-methylguanosine (m(1)G37), which prevents frameshifting and is present adjacent to and 3' of the anticodon (position 37) in the same subset of tRNAs from all organisms, including that with the smallest sequenced genome (Mycoplasma genitalium), and organelles. We have identified the genes encoding the enzyme tRNA(m(1)G37)methyltransferase from all three domains. We also show that they are orthologues, and suggest that they originated from a primordial gene. Lack of m(1)G37 severely impairs the growth of a bacterium and a eukaryote to a similar degree. Yeast tRNA(m(1)G37)methyltransferase also synthesizes 1-methylinosine and participates in the formation of the Y-base (yW). Our results suggest that m(1)G37 existed in tRNA before the divergence of the three domains, and that a tRNA(m(1)G37)methyltrans ferase is part of the minimal set of gene products required for life.

Climate Change : Believing and seeing implies adapting

Tidskriftsartikel (refereegranskat)abstract
- Knowledge of factors that trigger human response to climate change is crucial for effective climate change policy communication. Climate change has been claimed to have low salience as a risk issue because it cannot be directly experienced. Still, personal factors such as strength of belief in local effects of climate change have been shown to correlate strongly with responses to climate change and there is a growing literature on the hypothesis that personal experience of climate change (and/or its effects) explains responses to climate change. Here we provide, using survey data from 845 private forest owners operating in a wide range of bio-climatic as well as economic-social-political structures in a latitudinal gradient across Europe, the first evidence that the personal strength of belief and perception of local effects of climate change, highly significantly explain human responses to climate change. A logistic regression model was fitted to the two variables, estimating expected probabilities ranging from 0.07 (SD 60.01) to 0.81 (SD 60.03) for self-reported adaptive measures taken. Adding socio-demographic variables improved the fit, estimating expected probabilities ranging from 0.022 (SD 60.008) to 0.91 (SD 60.02). We conclude that to explain and predict adaptation to climate change, the combination of personal experience and belief must be considered.

- We tested two consequences of a currently influential theory based on the notion of seeing adaptations to climate change as local adjustments to deal with changing conditions within the constraints of the broader economic-social-political arrangements. The notion leaves no explicit role for the strength of personal beliefs in climate change and adaptive capacity. The consequences were: (i) adaptive action to climate change taken by an individual who is exposed to and sensitive to climate change is not influenced to a considerable degree by their strength of belief in climate change and (ii) adaptive action to climate change taken by an individual who is exposed to and sensitive to climate change is not influenced to a considerable degree by their strength of belief in an adaptive capacity. Data from a 2004 questionnaire of 1950 Swedish private individual forest owners, who were assumed exposed to and sensitive to climate change, were used. Strength of belief in climate change and adaptive capacities were found to be crucial factors for explaining observed differences in adaptation among Swedish forest owners. (C) 2008 Elsevier Ltd.

Tidskriftsartikel (refereegranskat)abstract
- The European Commission expects the use of biomass for energy in the EU to increasesignificantly between 2010 and 2020 to meet a legally binding target to cover at least 20%of EU’s total energy use from renewable sources in 2020. According to estimates made bythe member states of the EU, the direct supply of biomass from forests is expected toincrease by 45% on a volume basis between 2006 and 2020 in response to increasingdemand (Beurskens LWM, Hekkenberg M, Vethman P. Renewable energy projections aspublished in the national renewable energy action plans of the European Member states.ECN and EEA; 2011. http://https://www.ecn.nl/docs/library/report/2010/e10069.pdf[accessed 25.04.2014]; Dees M, Yousef A, Ermert J.

FELIS e Departmentof Remote Sensing and landscape information Systems, University of Freiburg,Germany; 2011). Our aims were to test the hypotheses that European private forestowners’ attitudes towards supplying woody biomass for energy (1) can be explained bytheir responses to changes in prices and markets and (2) are positive so that the forestbiomass share of the EU 2020 renewable energy target can be met. Based on survey datacollected in 2010 from 800 private forest owners in Sweden, Germany and Portugal ourresults show that the respondents’ attitudes towards supplying woody biomass for energycannot be explained as direct responses to changes in prices and markets. Our results,furthermore, imply that European private forest owners cannot be expected tosupply the requested amounts of woody biomass for energy to meet the forest biomassshare of the EU 2020 renewable energy target, at least if stemwood is to play theimportant role as studies by Verkerk PJ, Anttila P, Eggers J, Lindner M, Asikainen A.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Behovet av ny kunskap i anslutning till klimatförändringen är enormt. Det behövs ny kunskap om hur • klimatet kan komma att utvecklas. • skogsekosystemet kan komma att utvecklas. • dessa system interagerar. Detta kunskapsuppbyggande är högst angeläget att påbörja men kommer att ta tid. Många beslut inom skogsbruket måste fattas redan idag utan tillgång till forskningsresultaten. Man tvingas alltså redan nu förhålla sig till ett osäkert klimat. Därför, och för att det trots allt alltid kommer att finnas osäkerhet inför framtiden, vill vi stödja besluten genom att utveckla ett rationellt förhållningssätt till osäkerhet och risk. För att snabbt kunna ta fram praktiskt användbar kunskap vill vi i hög grad utgå från skogliga beslutssituationer när vi väljer vilka problemställningar vi ska hantera inom programmet. Framtagandet av ny kunskap skapar i sig ett problem för riskkommunikation. Kunskapsklyftan i förhållande till mottagaren ökar. Att överbrygga den klyftan är en av de viktigaste faktorerna för att lyckas förändra mottagarens kunskapsläge, och därigenom dennes beteende.

The role of beliefs, expectations and values in decision-making favoring climate change adaptation : implications for communications with European forest professionals
- 2020
-
Ingår i: Environmental Research Letters. - : IOP Publishing. - 1748-9326.
-
Tidskriftsartikel (refereegranskat)abstract
- Beliefs, expectations and values are often assumed to drive decisions about climate change adaptation. We tested hypotheses based on this assumption using survey responses from 508 European forest professionals in 10 countries. We used the survey results to identify communication needs and the decision strategies at play, and to develop guidelines on adequate communications about climate change adaptation. We observed polarization in the positive and negative values associated with climate change impacts accepted by survey respondents. We identified a mechanism creating the polarization that we call the 'blocked belief' effect. We found that polarized values did not correlate with decisions about climate change adaptation. Strong belief in the local impacts of climate change on the forest was, however, a prerequisite of decision-making favoring adaptation. Decision-making in favor of adaptation to climate change also correlated with net values of expected specific impacts on the forest and generally increased with the absolute value of these in the absence of "tipping point" behavior. Tipping point behavior occurs when adaptation is not pursued in spite of the strongly negative or positive net value of expected climate change impacts. We observed negative and positive tipping point behavior, mainly in SW Europe and N-NE Europe, respectively. In addition we found that advice on effective adaptation may inhibit adaptation when the receiver is aware of effective adaptation measures unless it is balanced with information explaining how climate change leads to negative impacts. Forest professionals with weak expectations of impacts require communications on climate change and its impacts on forests before any advice on adaptation measures can be effective. We develop evidence-based guidelines on communications using a new methodology which includes Bayesian machine learning modeling of the equivalent of an expected utility function for the adaptation decision problem.

To Mitigate or Adapt? : Explaining Why Citizens Responding to Climate Change Favour the Former
- 2021
-
Ingår i: Land. - : MDPI AG. - 2073-445X. ; 10:3
-
Tidskriftsartikel (refereegranskat)abstract
- Why do citizens’ decisions made because they favour the mitigation of climate change outnumber those made because they favour adaptation to its impacts? Using data collected in a survey of 338 citizens of Malmö, Sweden, we tested two hypotheses. H1: the motivation for personal decisions because they favour adaptation to the impacts of climate change correlates with the decision-making agent´s knowledge of specific local impacts of climate change, and H2: the motivation for personal decisions because they favour mitigation of climate change correlates with the risk perception of the decision-making agent. While decisions made because they favour mitigation correlated with negative net values of expected impacts of climate change (risk perception), decisions made because they favour adaptation correlated with its absolute value unless tipping point behaviour occurred. Tipping point behaviour occurs here when the decision-making agent abstains from decisions in response to climate change in spite of a strongly negative or positive net value of expected impacts. Hence, the decision-making agents´ lack of knowledge of specific climate change impacts inhibited decisions promoting adaptation. Moreover, positive experiences of climate change inhibited mitigation decisions. Discussing the results, we emphasised the importance of understanding the drivers of adaptation and mitigation decisions. In particular, we stress that attention needs to be paid to the balance between decisions solving problems ‘here and now’ and those focusing on the ‘there and then’.

Relationships between gene transcription and contaminant concentrations in Baltic ringed seals : A comparison between tissue matrices
- 2022
-
Ingår i: Aquatic Toxicology. - : Elsevier BV. - 0166-445X .- 1879-1514. ; 242
-
Tidskriftsartikel (refereegranskat)abstract
- Ringed seals (Pusa hispida) are slowly recovering in the eastern and northern parts of the Baltic Sea after years of hunting pressure and contaminant exposure. Still, consequences of anthropogenic activities such as contaminant exposure and increasing temperatures are stressors that continue to have deleterious effects on their habitat and health. Transcription profiles of seven health-related genes involved in xenobiotic metabolism, endocrine disruption and stress were evaluated in blood, blubber, and liver of Baltic ringed seals in a multi-tissue approach. Selected persistent organic pollutants and total mercury concentrations were measured in blubber and liver, and muscle and liver of these animals, respectively. Concentrations of contaminants varied across tissues on a lipid weight basis but not with sex. mRNA transcript levels for all seven target genes did not vary between sexes or age classes. Transcript levels of thyroid hormone receptor alpha (TR alpha), retinoic acid receptor alpha (RAR alpha) and heat shock protein 70 (HSP70) correlated with levels of persistent organic pollutants. TR alpha transcript levels also correlated positively with mercury concentrations in the liver. Of the three tissues assessed in this multi-tissue approach, blubber showed highest transcription levels of aryl hydrocarbon receptor nuclear translocator (ARNT), thyroid stimulating hormone receptor beta (TSH beta), oestrogen receptor alpha (ESR1) and peroxisome proliferator activated receptor alpha (PPAR alpha). The wide range of genes expressed highlights the value of minimally invasive sampling (e.g. biopsies) for assessing health endpoints in free-ranging marine wildlife and the importance of identifying optimal matrices for targeted gene expression studies. This gene transcript profile study has provided baseline information on transcript levels of biomarkers for early on-set health effects in ringed seals and will be a useful guide to assess the impacts of environmental change in Baltic pinnipeds for conservation and management.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: Randomized clinical trials have consistently demonstrated the non-inferiority of bioabsorbable polymer drug-eluting stents (BP-DES) with respect to DES having permanent polymers (PP-DES). To date, the comparative performance of BP- and PP-DES in the real world has not been extensively investigated.METHODS AND RESULTS: From October 2011 to June 2016, we analysed the outcomes associated with newer generation DES use in Sweden. After stratification according to the type of DES received at the index procedure, a total of 16 504 and 79 106 stents were included in the BP- and PP-DES groups, respectively. The Kaplan-Meier estimates for restenosis at 2 years were 1.2% and 1.4% in BP- and PP-DES groups, respectively. Definite stent thrombosis (ST) was low in both groups (0.5% and 0.7% in BP- and PP-DES groups, respectively). The adjusted hazard ratio (HR) for either restenosis or definite ST did not differ between BP- and PP-DES [adjusted HR 0.95, 95% confidence interval (CI) 0.74-1.21; P = 0.670 and adjusted HR 0.79, 95% CI 0.57-1.09; P = 0.151, respectively]. Similarly, there were no differences in the adjusted risk of all-cause death and myocardial infarction (MI) between the two groups (adjusted HR for all-cause death 1.01, 95% CI 0.82-1.25; P = 0.918 and adjusted HR for MI 1.05, 95% CI 0.93-1.19; P = 0.404).CONCLUSION: In a large, nationwide, and unselected cohort of patients, percutaneous coronary intervention with BP-DES implantation was not associated with an incremental clinical benefit over PP-DES use at 2 years follow-up.

DIOXINS AND OTHER POPS IN THE BALTIC SEA – TRENDS AND CURRENT
- 2009
-
Ingår i: 29th International Symposium on Halogenated Persistent Organic Pollutants (Dioxin 2009) in Bejing, China, August 25-30, 2009.
-
Konferensbidrag (refereegranskat)abstract
- This paper summarizes a project that was initiated by the Swedish Environmental Protection Agency (EPA) in 2006. It involved several field studies and fate model calculations with the aim to better understand the present contamination situation of dioxins and other persistent organic pollutants (POPs) in the Baltic Sea region. Atmospheric inputs were found to be the dominant external source for all of the selected POPs (dioxins, PCBs and HCB). The model also predicted a significant decline of POP-levels in Baltic surface water if atmospheric concentrations are reduced. This issue is highly prioritized by the Swedish EPA since TEQ-levels of fatty fish exceed maximum residue limits set by the EU. Dioxin source regions were identified by air measurements and analysis of air mass origin. It was found that air that had passed over the European continent contained the highest concentrations, and the congener composition indicated that several major sources types may exist. This research has high relevance for the Swedish EPA, and continued efforts for resolving the dioxin issue of the Baltic Sea will follow.

Prevalence and risk factors for transactional sex among Swedish-born and foreign-born MSM in Sweden
- 2022
-
Ingår i: BMC Public Health. - : BioMed Central (BMC). - 1471-2458. ; 22
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Little is known about transactional sex (TS) (selling and buying sex) among men who have sex with men (MSM) in Sweden, especially among foreign-born MSM. This study aims to assess the prevalence and risk factors of TS (ever and in the previous five years) among MSM living in Sweden and to determine if there is a difference between Swedish-born MSM and foreign-born MSM.Methods: Swedish data from a multicountry online banner survey (EMIS-2017) was used (n = 4443). Multivariable regression analysis was applied to analyse the data.Results: The prevalence of ever-selling sex among all MSM participants was 13.2% and 5.9% in the previous five years. Selling sex ever and in the previous five years was higher among foreign-born MSM (16% and 8.4%, respectively) than Swedish-born MSM (12.7% and 5.4%, respectively). Among all participants, younger age (aOR:3.19, 95% CI:1.57-6.45) and really struggling to live on current income (aOR:3.37, 95% CI:2.29-4.96) increased the odds of selling sex. Being foreign-born MSM (aOR:1.33, 95% CI:1.02-1.73) and having had sex with a woman in the previous 12 months increased the odds of selling sex (aOR:1.44, 95% CI:1.00-2.07). The prevalence of ever buying sex among MSM participants in Sweden was 10.8% and 6.7% in the previous five years, with the same trend among foreign-born MSM (11.6% and 6.9%, respectively) and Swedish-born MSM (10.7% and 6.6%, respectively). Higher education and not having a current partner increased the odds of buying sex. Younger age was protective for buying sex (aOR:0.05, 95% CI:0.02-0.14). Among the foreign-born MSM, the length of stay in Sweden decreased the odds of buying sex (aOR: 0.98, 95% CI: 0.96-0.99).Conclusions: The comparatively high prevalence of TS among MSM participants in Sweden, where buying sex is illegal, with a higher prevalence among foreign-born MSM participants, calls for sexual and reproductive health and rights interventions in this population. Increased attention, including HIV prevention programming and education, should be aimed at younger MSM, MSM struggling with their current income, and foreign-born MSM, as they are more likely to report selling sex.

Spectroscopic studies of aluminum and gallium complexes with oxalate and malonate in aqueous solution
- 2003
-
Ingår i: Journal of Molecular Structure. ; 648:3, s. 225-35
-
Tidskriftsartikel (refereegranskat)abstract
- The local structures of Ga(III) in aqueous oxalate and malonate complexes were studied by means of Ga K-edge EXAFS spectroscopy. Irrespective of the number and type of coordinated ligands, the EXAFS results showed very regular first coordination shells consisting of six oxygen atoms. Scattering paths from more distant atoms revealed that both oxalate and malonate form mononuclear chelate structures where one oxygen from each carboxylate group binds to Ga(III). Again, very little variation in bond distances and no changes in coordination modes were detected as the number of ligands coordinated to Ga(III) was varied. Based on the very close resemblance of IR spectra of oxalate and malonate complexes of Al(III), and the corresponding complexes of Ga(III), it is believed that the local structures of the Al(III) complexes are similar to those of the Ga(III) complexes in terms of ligand coordination modes and distortions. This conclusion was corroborated by results from theoretical frequency calculations.

Freely Dissolved Concentrations and Sediment-Water Activity Ratios of PCDD/Fs and PCBs in the Open Baltic Sea
- 2008
-

Tidskriftsartikel (refereegranskat)abstract
- Aqueous concentrations of polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs) as well as polychlorinated biphenyls (PCBs) in the open sea have heretofore been measured by filtering. and extracting large amounts of water. Measurement of freely dissolved concentrations with this technique is difficult because of corrections for sorption to dissolved organic matter. In this study we use a novel, more economic technique using equilibrium passive samplers consisting of 17-mu m thin polyoxymethylene (POM-17), capable of measuring freely dissolved aqueous concentrations (C-W) in pristine (i.e., background) locations. POM-17 was employed in an extensive field campaign at five stations in the open Baltic sea to obtain C-W at two depths (1 m above the seafloor and 25 m below the surface). Median C-W in the overlying water was 2.3 pg toxic equivalents (TEQ)/m(3) PCDD/Fs and 15 pg/L sum 7-PCB, with generally less than a factor two variation among sites and depths. Also freely dissolved concentrations of native compounds in the surface sediment porewater (C-PW) were determined in laboratory batch experiments. The data were used to derive sediment-water activity ratios, which indicate the diffusive flux direction. It was found that the PCDD/Fs and PCBs were in close equilibrium between the sediment porewater and the overlying water. Comparison of C-PW with total sediment concentrations indicated that more than 90% of the compounds were sorbed to sedimentary black carbon.
