    Advances in Task-Based Parallel Programming for Distributed Memory Architectures2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. In task-based programming, all the variables in the program are abstractly viewed as data. Parallelism is provided by partitioning the data. A task is a collection of operations performed on input data to generate output data. In distributed memory environments, the data is distributed over the computational nodes (or processes), and is communicated when a task needs remote data.

    This thesis discusses advanced techniques in distributed task-based parallel programming, implemented in the DuctTeip software library. DuctTeip uses MPI (Message Passing Interface) for asynchronous inter-process communication and Pthreads for shared memory parallelization within the processes. The data dependencies that determine which subsets of tasks can be executed in parallel are extracted from information about the data accesses (input or output) of the tasks. A versioning system is used internally to represent the task-data dependencies efficiently. A hierarchical partitioning of tasks and data allows for independent optimization of the size of computational tasks and the size of communicated data. A data listener technique is used to manage communication efficiently.

    DuctTeip provides an algorithm independent dynamic load balancing functionality. Redistributing tasks from busy processes to idle processes dynamically can provide an overall shorter execution time. A random search method with high probability of success is employed for locating idle/busy nodes.

    The advantage of the abstract view of tasks and data is exploited in a unified programming interface, which provides a standard for task-based frameworks to decouple framework development from application development. The interface can be used for collaboration between different frameworks in running an application program efficiently on different hardware.

    To evaluate the DuctTeip programming model, applications such as Cholesky factorization, a time-dependent PDE solver for the shallow water equations, and the fast multipole method have been implemented using DuctTeip. Experiments show that DuctTeip provides both scalability and performance. Comparisons with similar frameworks such as StarPU, OmpSs, and PaRSEC show competitive results.

    Modelling and Simulation for Evaluation of Cooperative Intelligent Transport System Functions2016Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Future vehicles are expected to be equipped with wireless communication tech- nology, that enables them to be “connected” to each others and road infras- tructures. Complementing current autonomous vehicles and automated driving systems, the wireless communication allows the vehicles to interact, cooperate, and be aware of its surroundings beyond their own sensors’ range. Such sys- tems are often referred to as Cooperative Intelligent Transport Systems (C-ITS), which aims to provide extra safety, efficiency, and sustainability to transporta- tion systems. Several C-ITS applications are under development and will require thorough testing and evaluation before their deployment in the real-world. C- ITS depend on several sub-systems, which increase their complexity, and makes them difficult to evaluate.

    Simulations are often used to evaluate many different automotive appli- cations, including C-ITS. Although they have been used extensively, simulation tools dedicated to determine all aspects of C-ITS are rare, especially human fac- tors aspects, which are often ignored. The majority of the simulation tools for C-ITS rely heavily on different combinations of network and traffic simulators. The human factors issues have been covered in only a few C-ITS simulation tools, that involve a driving simulator. Therefore, in this thesis, a C-ITS simu- lation framework that combines driving, network, and traffic simulators is pre- sented. The simulation framework is able to evaluate C-ITS applications from three perspectives; a) human driver; b) wireless communication; and c) traffic systems.

    Cooperative Adaptive Cruise Control (CACC) and its applications are cho- sen as the first set of C-ITS functions to be evaluated. Example scenarios from CACC and platoon merging applications are presented, and used as test cases for the simulation framework, as well as to elaborate potential usages of it. Moreover, approaches, results, and challenges from composing the simulation framework are presented and discussed. The results shows the usefulness of the proposed simulation framework.

    Long-term effects of complications and vascular comorbidity in idiopathic normal pressure hydrocephalus: a quality registry study2018Inngår i: Journal of Neurology, ISSN 0340-5354, E-ISSN 1432-1459, Vol. 265, nr 1, s. 178-186Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: There is little knowledge about the factors influencing the long-term outcome after surgery for idiopathic normal pressure hydrocephalus (iNPH).

    Objective: To evaluate the effects of reoperation due to complications and of vascular comorbidity (hypertension, diabetes, stroke and heart disease) on the outcome in iNPH patients, 2–6 years after shunt surgery.

    Methods: We included 979 patients from the Swedish Hydrocephalus Quality Registry (SHQR), operated on for iNPH during 2004–2011. The patients were followed yearly by mailed questionnaires, including a self-assessed modified Rankin Scale (smRS) and a subjective comparison between their present and their preoperative health condition. The replies were grouped according to the length of follow-up after surgery. Data on clinical evaluations, vascular comorbidity, and reoperations were extracted from the SHQR.

    Results: On the smRS, 40% (38–41) of the patients were improved 2–6 years after surgery and around 60% reported their general health condition to be better than preoperatively. Reoperation did not influence the outcome after 2–6 years. The presence of vascular comorbidity had no negative impact on the outcome after 2–6 years, assessed as improvement on the smRS or subjective improvement of the health condition, except after 6 years when patients with hypertension and a history of stroke showed a less favorable development on the smRS.

    Conclusion: This registry-based study shows no negative impact of complications and only minor effects of vascular comorbidity on the long-term outcome in iNPH.

    Informal Learning as a Challenge for School Development: Operationalizing the Tacit Dimensions of Democracy Education2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    By the concept of informal learning the fact can be grasped scientifically that we present our orientation in the everyday-world, our social engagement and our capabilities in different fields sometimes rather apart from our school knowledge. Informal learning nowadays plays a central role in scientific psychology and in education policy. Hence, different tools for the validation of informal learning have been developed (see: EQF, ECVET, ECTS, EQARF, EUROPASS). Informal learning is here mainly considered in terms of the acquisition of qualifications and vocational training. The theoretical aim of my contribution is to unfold a pedagogical understanding of informal learning. Here, I will stick to the hypothesis that considering informal learning in democracy education is a form of promoting disadvantaged learners. Hereby, the achievement gap is supposed to be reduced and the new social question is defused (cp. also Helsper 2001, Helsper & Lingkost 2001, Reich 2005, Abs & Verldhuis 2008, et al.). The principle of educational equality is deeply connected to the idea of democracy, especially according to John Deweys (1916, 1933) concept of „democracy as a way of life“. Informal learning eludes the governmental approach in pedagogy (Dohmen 2001 et al.). It has the character of implicit learning, including procedural, contextual, pre-reflexive, sensory aspects, and can be regarded as part of concepts such as experience-based learning, self-directed, or competence-oriented learning, etc. (Reber 1993 et al.). Our research on the tacit dimensions in pedagogy (Bergstedt et al. 2012) has shown that on one side informal learning is the indispensable basis of formal learning, that is to say, it makes learning possible. On the other side, it can be a hindrance for it. This is true e.g. for habitual insularities, indispensable conflicts of norms, or values that cause ideological narrow-mindedness.

    Methodology, Methods, Research Instruments or Sources Used By referring to the results of different empirical studies on democracy education and democracy in schools, I will work out what this means for the operationalization of the different aspects of democracy education: Conclusions, Expected Outcomes or Findings I present a schedule for the operationalization of the impact of informal learning on democracy education.

    Competition in Public Transport: Essays on competitive tendering and open-access competition in Sweden2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. With respect to the competitive environment, it was found that many contract design factors have little or no effect on the number of bids that the PTA sees in their tenders. No measure that could be imposed by a single PTA was found to increase the total number of bidders by more than 0.5 bidders. However, the results suggest that PTAs as a collective could try to avoid tendering too many contracts at the same time because this was shown to reduce participation by up to about two bidders. In addition, these studies show that the local competitive environment is important for the PTAs to consider. The way in which contract areas are defined will also affect the participation rate as operators were found to participate in tenders to a lower extent the farther their workplaces are from the contract area. While larger operators appear to be less sensitive with respect to such distances, the fact that smaller operators are, and that they often bid as one unit as members of cooperation companies, makes the competitive environment important. The results suggest that depots could be included in the contract to stimulate participation, but this is by no means the only nor an easy solution.

    This thesis has also analyzed the entry made in 2015 by MTR Express (MTR) on the Stockholm-Gothenburg railway line. The overall conclusion is that customers are indeed facing lower prices one and a half years after the entry. MTR's prices are on average 100 SEK lower than the incumbent SJ's prices. Furthermore, the analysis shows that the incumbent’s prices have also gone down, by almost 13 percent, following the entry.

    Auxin and ROP GTPase Signaling of Polar Nuclear Migration in Root Epidermal Hair Cells2018Inngår i: Plant Physiology, ISSN 0032-0889, E-ISSN 1532-2548, Vol. 176, nr 1, s. 378-391Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Polar nuclear migration is crucial during the development of diverse eukaryotes. In plants, root hair growth requires polar nuclear migration into the outgrowing hair. However, knowledge about the dynamics and the regulatory mechanisms underlying nuclear movements in root epidermal cells remains limited. Here, we show that both auxin and Rho-of-Plant (ROP) signaling modulate polar nuclear position at the inner epidermal plasma membrane domain oriented to the cortical cells during cell elongation as well as subsequent polar nuclear movement to the outer domain into the emerging hair bulge in Arabidopsis (Arabidopsis thaliana). Auxin signaling via the nuclear AUXIN RESPONSE FACTOR7 (ARF7)/ARF19 and INDOLE ACETIC ACID7 pathway ensures correct nuclear placement toward the inner membrane domain. Moreover, precise inner nuclear placement relies on SPIKE1 Rho-GEF, SUPERCENTIPEDE1 Rho-GDI, and ACTIN7 (ACT7) function and to a lesser extent on VTI11 vacuolar SNARE activity. Strikingly, the directionality and/or velocity of outer polar nuclear migration into the hair outgrowth along actin strands also are ACT7 dependent, auxin sensitive, and regulated by ROP signaling. Thus, our findings provide a founding framework revealing auxin and ROP signaling of inner polar nuclear position with some contribution by vacuolar morphology and of actin-dependent outer polar nuclear migration in root epidermal hair cells.

    Non-Exhaust PM10 and Road Dust2018Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. Given this, the purpose of the thesis was to give an overview limited to Sweden and the Nordic countries regarding non-exhaust PM10 emissions and road dust.

    The overview includes how particles are related to human health. Also included is the principle of how particles are emitted from road surface and tyre interaction, both directly and through resuspension of road dust. This thesis also includes an overview of how the use of studded tyres impact on asphalt surfacings and how the properties of the materials used impact on the abrasion wear. This is then linked to the emissions of non-exhaust particles. Further described is how measurements can be done of ambient particles and road dust, followed on two major models for road abrasion wear and non-exhaust PM prediction. Also included is how road operation, e.g. traction sanding and dust binding, influence the particle emissions together with other options to reduce the emissions through, e.g. limiting the use of studded tyres.

    One special issue discussed in this thesis is the lack of holistic view regarding the environmental problems in the urban environment with focus on particle emissions and road noise emissions, both from the road surface and tyre interaction. Currently the most problematic issue is prioritized and the resulting solution to that specific problem might increase other problems.

    This thesis shows that much knowledge is available regarding non-exhaust PM10 emissions and road dust, but also that several knowledge gaps exists. Several suggestions on further studies is given together with a brief overview on the continued work forward from this thesis.

    Using Theories of Change to inform implementation of health systems research and innovation: experiences of Future Health Systems consortium partners in Bangladesh, India and Uganda2017Inngår i: Health Research Policy and Systems, ISSN 1478-4505, E-ISSN 1478-4505, Vol. 15, artikkel-id 109Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The Theory of Change (ToC) is a management and evaluation too ! supporting critical thinking in the design, implementation and evaluation of development programmes. We document the experience of Future Health Systems (FHS) Consortium research teams in Bangladesh, India and Uganda with using ToC. We seek to understand how and why ToCs were applied and to clarify how they facilitate the implementation of iterative intervention designs and stakeholder engagement in health systems research and strengthening.

    Methods: This paper combines literature on ToC, with a summary of reflections by FHS research members on the motivation, development, revision and use of the ToC, as well as on the benefits and challenges of the process. We describe three FHS teams' experiences along four potential uses of ToCs, namely planning, communication, learning and. accountability.

    Results: The three teams developed ToCs for planning and. evaluation purposes as required for their initial plans for FHS in 2011 and. revised, them half-way through the project, based on assumptions informed, by and adjusted, through the teams' experiences during the previous 2 years of implementation. All teams found that the revised ToCs and their accompanying narratives recognised greater feedback among intervention components and among key stakeholders. The ToC development and. revision fostered, channels for both internal and external communication, among research team members and. with key stakeholders, respectively. The process of revising the ToCs challenged the teams' initial assumptions based on new evidence and experience. In contrast, the ToCs were only minimally used for accountability purposes.

    Conclusions: The ToC development and revision process helped FHS research teams, and occasionally key local stakeholders, to reflect on and make their assumptions and mental models about their respective interventions explicit. Other projects using the ToC should allow time for revising and reflecting upon the ToCs, to recognise and document the adaptive nature of health systems, and to foster the time, space and flexibility that health systems strengthening programmes must have to learn from implementation and stakeholder engagement.

    Teachers work: The tacit pedagogy of expert teachers in rural Malawi2017Inngår i: Presented at EADI-NORDIC 2017, 2017Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The status of school teachers in much ofrural Sub-Saharan Africa has a dual nature across many different countries. At the local level they are influential social actors, respectable people who are expected to provide a positive role model to their pupils and the wider local community. Within the national civil service, they are not often treated as very important - sometimes paid intermittently and frequently problematised as lacking in the capacit to deliver ambitious education-led national development strategies.

    In this paper we report on the results of a pilot study in rural Malawi, which sort to investigate the tacit knowledge and pedagogical skills of primary school teachers using participatory visual methods. Around a three week participatory video exercise with teachers from two schools, a combination of participatory action research, participant-observation, semi-structured and photo-elcited interviews and group reflection was analysed to understand how different data-gathering and analytical techniques could combine to surface and valorise the teachers' knowledge.

    Rather than a lack of skills and capacity, the data instead showed the range of skills and personal characteristics involved in the teachers' practice. Cognitive mapping on a subset of the data showed that the concept of active learning operationalised independently at two schools was (i) consisten, (ii) informed sophisticated practice, and (iii) was richer than that embedded in much external expert knowledge about teaching

    Graphite oxides for preparation of graphene related materials: structure, chemical modification and hydrogen storage properties2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Carbon materials have been studied for hydrogen storage for decades, but they showed too low capacity at ambient temperature compared to target values for practical applications. This thesis includes two parts. First one is fundamental study of graphite oxides (GO) structure and properties. Second part is focused on hydrogen storage properties of graphene related materials prepared using GO as a precursor.

    We studied the effects of synthesis methods and oxidation degree on solvation/intercalation properties of GOs. New effect of temperature induced reversible delamination was observed for Hummers GO (HGO) immersed in liquid acetonitrile. Experiments with swelling of Brodie GO (BGO) in 1-octanol revealed parallel orientation of the intercalated solvent molecules relative to graphene oxide (GnO) layers. Chemical functionalization of GO in swelled state allowed us to synthesize the materials with subnanometer slit pores supported by molecular pillars. Structure and properties of pillared GO were characterized by variety of methods. Swelling properties of multilayered GnO membranes were compared to properties of precursor GO. GnO membranes were found to swell similarly to GO powders in some solvents and rather differently in other. Our experiments revealed important limitations in application of GO membranes for nanofiltration. Several parameters were found to affect the size of permeation “channels” provided by interlayers of GnO membrane structure: e.g. nature of solvent, pH of solutions and concentration of solutes.

    Hydrogen storage parameters were studied for a set of graphene related materials with broad range of surface areas (SSA) (200 - 3300 m2/g). Hydrogen sorption weight percent (wt%) is found to correlate with SSA for all studied graphene materials following the trend standard for other nanostructured carbon materials. The highest hydrogen uptakes of ~1.2 wt% at 296 K and ~7.5 wt% at 77 K were measured for graphene material with SSA of over 3000 m2/g. Addition of Pd and Pt nanoparticles to graphene materials did not resulted in improvement of hydrogen storage compared to nanoparticles-free samples. No deviation from the standard wt% vs. SSA trends was also observed for pillared GO materials. Therefore, hydrogen storage properties of graphene related materials at room temperatures are not confirmed to be exceptional. However, high surface area graphene materials are found to be among the best materials for physisorption of hydrogen at liquid nitrogen temperature. Moreover, hydrogen storage capacity of 4 wt%, comparable to target values, was observed at temperature of solid CO2 (193 K) which can be maintained using common refrigeration methods.

    Search for Dark Matter Produced in Association with a Higgs Boson Decaying to b¯b Using 36  fb−1 of pp Collisions at √s=13  TeV with the ATLAS Detector2017Inngår i: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 119, nr 18, artikkel-id 181804Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Several extensions of the standard model predict associated production of dark-matter particles with a Higgs boson. Such processes are searched for in final states with missing transverse momentum and a Higgs boson decaying to a b¯b pair with the ATLAS detector using 36.1  fb−1 of pp collisions at a center-of-mass energy of 13 TeV at the LHC. The observed data are in agreement with the standard model predictions and limits are placed on the associated production of dark-matter particles and a Higgs boson.

    Documenting Videogame Communities: A Study of Community Production of Information in Social-Media Environments and its Implications for Videogame Preservation2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Drawing on the disciplines of library and information studies and archival studies, this study seeks to explore the production of information in online videogame communities and to elucidate how such insights can offer practical and conceptual support to the knotty issue of how to preserve those sociocultural aspects of videogames that exist 'beyond' the code and audiovisual data resources of the videogame itself. This is accomplished in two principal moves: (i) by delving into the current state of socioculturally-focused videogame preservation and; (ii) by inquiring into the production of information carried out by videogame communities in what arguably is one of their most important interfaces of interaction—discussion forums, wikis, and other social-media services. The study is based on four papers (I–IV). Paper I develops the theoretical framework of the study on the basis of practice theory and document theory. Papers II and III report on field-studies of videogame-community information production in the context of two processes of importance in community social life: memory-making (II) and knowledge production (III). Paper IV offers a qualitative systematic review of videogame-archiving literature, allowing Papers I–III to be situated in an archival context. The study employs multiple methods and encompasses several empirical sites of inquiry and was inspired by the framework of exploratory research and of 'bricolage' research strategies.

    The results of the study add to the present state of knowledge on how information in the social-media environments of the large and influential present-day videogaming domain emerges as a result of community practices of production, and how videogame-community social life is entangled with information production in such spaces. The study also furthers archival inquiry on the topic of videogame preservation by providing a description and analysis of what information objects videogame-related social media plausibly hold, and by what communal practices and processes they have been brought into existence. Furthermore, the study examines the consequences of collecting community-produced social media and framing it as documentation of the sociocultural aspects of videogames—a key issue in videogames preservation.

    Abstract [en]

    BACKGROUND: Promotion of active commuting provides substantial health and environmental benefits by influencing air pollution, physical activity, accidents, and noise. However, studies evaluating intervention and policies on a mode shift from motorized transport to cycling have estimated health impacts with varying validity and precision.

    OBJECTIVE: To review and discuss the estimation of air pollution exposure and its impacts in health impact assessment studies of a shift in transport from cars to bicycles in order to guide future assessments.

    METHODS: A systematic database search of PubMed was done primarily for articles published from January 2000 to May 2016 according to PRISMA guidelines.

    RESULTS: We identified 18 studies of health impact assessment of change in transport mode. Most studies investigated future hypothetical scenarios of increased cycling. The impact on the general population was estimated using a comparative risk assessment approach in the majority of these studies, whereas some used previously published cost estimates. Air pollution exposure during cycling was estimated based on the ventilation rate, the pollutant concentration, and the trip duration. Most studies employed exposure-response functions from studies comparing background levels of fine particles between cities to estimate the health impacts of local traffic emissions. The effect of air pollution associated with increased cycling contributed small health benefits for the general population, and also only slightly increased risks associated with fine particle exposure among those who shifted to cycling. However, studies calculating health impacts based on exposure-response functions for ozone, black carbon or nitrogen oxides found larger effects attributed to changes in air pollution exposure.

    CONCLUSION: A large discrepancy between studies was observed due to different health impact assessment approaches, different assumptions for calculation of inhaled dose and different selection of dose-response functions. This kind of assessments would improve from more holistic approaches using more specific exposure-response functions.

    Structure of Rubisco from Arabidopsis thaliana in complex with 2-carboxyarabinitol-1,5-bis­phosphate2018Inngår i: Acta Crystallographica Section D: Biological Crystallography, ISSN 0907-4449, E-ISSN 1399-0047, ISSN 2059-7983, Vol. 74, nr 1, s. 1-9Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The crystal structure of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) from Arabidopsis thaliana is reported at 1.5 Å resolution. In light of the importance of A. thaliana as a model organism for understanding higher plant biology, and the pivotal role of Rubisco in photosynthetic carbon assimilation, there has been a notable absence of an A. thaliana Rubisco crystal structure. A. thaliana Rubisco is an L8S8 hexadecamer comprising eight plastome-encoded catalytic large (L) subunits and eight nuclear-encoded small (S) subunits. A. thaliana produces four distinct small-subunit isoforms (RbcS1A, RbcS1B, RbcS2B and RbcS3B), and this crystal structure provides a snapshot of A. thaliana Rubisco containing the low-abundance RbcS3B small-subunit isoform. Crystals were obtained in the presence of the transition-state analogue 2-carboxy-D-arabinitol-1,5-bisphosphate. A. thaliana Rubisco shares the overall fold characteristic of higher plant Rubiscos, but exhibits an interesting disparity between sequence and structural relatedness to other Rubisco isoforms. These results provide the structural framework to understand A. thaliana Rubisco and the potential catalytic differences that could be conferred by alternative A. thaliana Rubisco small-subunit isoforms.

    Förändringar och trenders påverkan på brandsäkerheten i bostäder2018Rapport (Annet vitenskapelig)
    Abstract [sv]

    År 2009 antog Myndigheten för samhällskydd och beredskap (MSB) en nationell strategi för dödsbränder. Denna syftade till att ingen skulle omkomma eller skadas allvarligt till följd av brand i Sverige - en s.k. nollvision. Årligen dör nästan hundra personer av brandrelaterade skador i Sverige och antalet omkomna har under senare år hållit sig relativt konstant även om det har minskat över en längre tid.

    Risken för att omkomma i brand utgår ifrån individens förutsättningar och levnadsförhållanden. Dessa förutsättningar påverkas till viss del av trendskiftningar i samhället. Denna rapport syftar till att identifiera och analysera trender som har en påverkan på individens risk för att dö till följd av brand. Rapporten syftar också till att identifiera vilka trender som det inte har forskats tillräckligt på för att kunna dra några slutsatser om dödsbrandsrisken. Slutligen ges en framtidsutsikt för trender där en sådan kan skönjas.

    Vad gäller detektion och släckning har mycket forskning tillägnats brandvarnare. Nya smarta system har införts på marknaden de senaste åren. Dessa har potential att förbättra brandsäkerheten, men mer forskning behövs. Detta gäller även andra system (utom brandvarnare); mer forskning behövs för att kunna visa en signifikant positiv effekt.

    En hel del forskning existerar vad gäller prediktion av brand i olika typer av byggnadsmaterial. Samtidigt införs nya och ”nygamla” material på bostadsmarknaden och bostäderna blir ”tätare” mot brand pga. t.ex. flerglasfönster och mer isolering. Nya bostäder tenderar också att byggas med öppnare planlösning än för 30 år sedan, även om bostadsytan i snitt per person inte har ändrats de senaste åren. Detta medför en ökad risk för snabb brand- och rökspridning inom brandcellen, men brännbara byggnadsmaterial kan också medföra ökad brandspridning utanför brandcellen om byggnadsregler inte efterföljs.

    Det finns en del kunskap om samhällets funktioner och tjänster, såsom sjukvård efter brand, räddningstjänst mm. men effektivitet och trendskiftningar är svåra att mäta.

    Olika individer löper olika stor risk att dö i brand beroende på t.ex. ekonomisk situation, ålder och livsstil. Vad gäller livsstil har antalet rökare i varje åldersgrupp stabiliserats något sedan nedgången efter rökförbudet på uteserveringar infördes år 2005. Däremot ökar alkoholkonsumtionen. Både antalet ensamboende och antalet trångbodda ökar, där båda grupperna har en förhöjd dödsbrandsrisk. Fler äldre med vårdbehov förutspås bo kvar i sina hem i framtiden. Äldre utgör en särskilt utsatt grupp vad gäller dödsbrand och därför bör riktade insatser göras vad gäller denna grupp för att uppfylla MSB:s nollvision.

    Eosinophilic granulomatosis with polyangiitis: myocardial thickening reversed by corticosteroids2017Inngår i: BMC Cardiovascular Disorders, ISSN 1471-2261, E-ISSN 1471-2261, Vol. 17, artikkel-id 299Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: In 1951 Churg and Strauss first described the clinical condition now known as eosinophilic granulomatosis with polyangiitis (EGPA), characterized by asthma, nasal polyposis, rhinosinusitis, hypereosinophilia with organ infiltration, and necrotizing vasculitis. It is classified as an antineutrophil cytoplasmic antibody (ANCA) associated vasculitis, but ANCA negativity is common and more frequently encountered in EGPA with myocardial involvement. Long-term survival has substantially improved with corticosteroid treatment but myocardial involvement is still the leading cause of death in EGPA.

    Case presentation: A 53-year old man with a history of asthma and nasal polyposis presented with acute chest pain and elevated troponin; a percutaneous coronary intervention was performed. The left ventricle was described as hypertrophic. After 20 days the myocardium had markedly increased in thickness of both the right and left ventricle. Evaluation revealed hypereosinophilia in the blood and nasal mucosal tissue, which confirmed the diagnosis of EGPA. He presented with signs of active vasculitis including weight loss, tiredness, intracerebral hemorrhage, and increasing serum creatinine. After 6 days of corticosteroid treatment, the myocardium returned to its initial thickness.

    Conclusion: Rapid and marked thickening of the myocardium is not frequently reported but may occur in EGPA. Myocardial thickening in EGPA can be quickly reversed by corticosteroids, and is most likely caused by edema.

    Probing cold dark matter subhaloes with simulated ALMA observations of macrolensed sub-mm galaxies2017Inngår i: Monthly notices of the Royal Astronomical Society, ISSN 0035-8711, E-ISSN 1365-2966, Vol. 472, nr 1, s. 129-140Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    If the dark matter haloes of galaxies contain large numbers of subhaloes as predicted by the Lambda cold dark matter model, these subhaloes are expected to appear in strong galaxy-galaxy lens systems as small-scale perturbations in individual images. We simulate observations of multiply lensed sub-mm galaxies at z similar to 2 as a probe of the dark matter halo of a lens galaxy at z similar to 0.5. We present detection limits for dark substructures based on a visibility plane analysis of simulated Atacama Large Millimeter/submillimeter Array (ALMA) data in bands 7, 8 and 9. We explore two effects: local surface brightness anomalies on angular scales similar to the Einstein radius and the astrometric shift of macroimages. This improves the sensitivity of our lens modelling to the mass of the lens perturber. We investigate the sensitivity of the detection of low-mass subhaloes to the projected position of the subhalo on the image plane as well as the source structure and inner density profile of the lens. We demonstrate that, using the most extended ALMA configuration, pseudo-Jaffe subhaloes can be detected with 99 per cent confidence down to M = 10(7)M(circle dot) . We show how the detection threshold for the three ALMA bands depends on the projected position of the subhalo with respect to the lensed images and conclude that, despite the highest nominal angular resolution, band 9 provides the poorest sensitivity due to observational noise. All simulations use the ALMA Full ops most extended ALMA configuration setup in CASA.

    Developing tools for non-target analysis and digital archiving of organic urban water pollutants2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis describes efforts to develop robust methods for the creation and use of digital archives of environmental samples, and proposes guidelines based on the results. Digital archives are repositories that store environmental samples digitally. Traditionally, samples are stored physically in environmental specimen banks over long time periods. However, this has several drawbacks, for example degradation effects and limited accessibility. During the course of my PhD project I developed methods that allow the comprehensive analysis of sewage sludge samples. Sewage sludge is a complex matrix that contains many commercial chemicals. In addition, sewage treatment plants form a link between the human society that generates the sewage and the environment, making sewage sludge a very interesting matrix to analyze. The developed methods enable analysis and subsequent identification of compounds of all sizes and with diverse chemical characteristics. I further explain how unknown compounds can be identified (non-target screening) using mass spectral analysis and several other approaches (e.g. retention indices).

    The thesis is divided into three parts. In the first part, Data Generation, I describe the development of sample preparation methods for analyzing sewage sludge with gas chromatography (GC) and liquid chromatography (LC) coupled to high resolution mass spectrometry (HRMS). For the GC approach, two methods involving use of different extraction techniques, solvents, and matrix reduction techniques are presented while for the LC approach different extraction techniques are compared. The methods have been developed to enable the generation of data suitable for digital archiving. In the second part of the thesis, Data Evaluation, I present ways to find and identify compounds of interest. Firstly, time trend analyses provide a way to prioritize pollutants, for example by focusing on pollutants that are increasing with time. Thousands of compounds with significant time trends were detected and several hundred of them were tentatively identified. Compounds with strong increasing trends included, for example, UV-filters from sunscreens. Secondly, a new retention index system for comprehensive two‑dimensional chromatography (GC×GC) is introduced to characterize compounds in terms of their retention times in the second dimension. The new retention index system is based on co-injection of polyethylene glycols and was validated for various compounds of diverse classes. Thirdly, I tested different ways to predict GC×GC retention times or indices. Those methods include a multivariate prediction (PLS) approach using molecular descriptors, which proved to be the best approach, and use of commercially available software. The last part of my thesis, Data Archiving, discusses requirements to create digital archives and how they can be used. Here I present the current state and options for archiving data files, and give recommendations for each step, from sample collection, through instrumental analysis to storage of the final data.

    Data quality in the National Prostate Cancer Register (NPCR) of Sweden2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background: Data in quality registers are increasingly used for quality assurance of health care, benchmarking, and research. If valid conclusions are to be drawn from such studies, it is vital that register data have high quality. The aim of this thesis was to assess data quality in the National Prostate Cancer Register (NPCR) of Sweden, a nationwide register that since 1998 captures 98% of all cases of Prostate cancer (Pca) in Sweden. The proportion and characteristics of Pca cases not registered in NPCR was investigated in paper I. Four dimensions of data quality were evaluated for NPCR in paper II: completeness, timeliness, comparability, and validity. Proportion and characteristics of Pca cases registered in NPCR but with unknown risk category were investigated in paper III. Finally, the association between Socioeconomic Status (SES) and Pca diagnosis, treatment, and mortality was studied in paper IV. 

    Material and methods: Data quality of NPCR was studied by cross-linkages between NPCR and other health care registers and demographical databases by use of the Swedish personal identity number. Validity was further studied by re-abstraction of patient health care records, followed by comparison of re-abstracted and original register data.

    Results: Men not registered in NPCR, who constituted around 2% of all cases in the Swedish Cancer Register, differed only modestly in characteristics from cases in NPCR, indicating that NPCR is generalizable for all men with Pca in Sweden. Data quality in NPCR was high overall, with high completeness compared to the Swedish Cancer Register with registration mandated by law and few Pca cases were detected by use of death certificates. There was timely registration, and good comparability with registration forms and coding routines that were compliant with international guidelines. Data validity was high with high agreement and correlation for key variables. Men with unknown risk category had, compared to men with known risk category, more often concomitant bladder cancer, higher comorbidity, and lower Pca mortality. Men with high SES had, compared to men with low SES, higher probability of Pca detected during health checkup, shorter waiting times for prostatectomy, and higher probability of curative treatment for intermediate and high-risk cancer. Pca mortality was lower in men with high SES than in men with low SES for high-risk cancer.

    Conclusion: These results indicate that data quality in NPCR is high and that NPCR is population-based. There were consistent differences in diagnostic and therapeutic activity according to SES despite an equal access tax-financed healthcare system in Sweden.

    Diffusion of systemic innovations in the construction sector2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The amount of research dealing with innovation has increased dramatically, construction management research included. This thesis focuses on innovations with inter-organizational effects, systemic innovations, which may radically change and improve the construction process. The overall aim of the thesis is to contribute understanding of diffusion of systemic innovations in the construction sector through the study of two different types of systemic innovations, Building Information Management and Multi-Story Housing in Timber (MSHT). It explores what facilitates and hinders innovation diffusion, with a special focus on knowledge integration and mechanisms used in the diffusion process and their effects on knowledge development. The studies conducted were made in a Swedish context related to two separate companies work with diffusing the innovations, using a broad approach with different data collection methods.

    The research departures in the interplay between the innovation content, context and process through which diffusion take place, displaying differences in how diffusion precedes and is affected. Where organizations are situated in the construction process and their ability to control the diffusion process is influential and diffusion is affected by established traditions and work procedures. For MSHT other structural materials form obstacles, while for BIM it is established work procedures and methods. Environmental pressure drives diffusion of MSHT and both innovations are supported by active clients. Diffusion also requires financial resources depending on the size of investment and associated risks. The cases show advantages with moving activities from projects into a continuous business that delivers to projects, where simplifying implementation is central. Mainly due to complexity, developing in steps enables simplifications and adjustments towards users in a controlled manner. MSHT to a higher degree depends on performing real projects for development and diffusion than BIM, which can be tested to a larger extent before diffusing into the real environment. MSHT in particular show a difference in relation to many traditional models of innovation and innovation diffusion where tests are assumed possible.

    The research relates to and has emphasized interaction and dynamics in the diffusion process and has provided additional understanding for managing complexity in the diffusion process. Projects are the most crucial knowledge integration mechanism with many underlying mechanisms, since they are a result of the development and show consequences of work performed. The applicability of codified knowledge in combination with more interactionintensive mechanisms has been shown and the introduction of the knowledge type’s domain-specific, procedural and general knowledge, complementing the current use of tacit and explicit knowledge, has provided additional understanding for diffusion and related knowledge flows. There are however differences in how knowledge types develop for the innovations. General knowledge is more influencing for BIM, while MSHT is about developing domain-specific knowledge. MSHT is about learning something new, while for BIM it is about re-learning. Findings show relevance in both using and developing the framework of innovation in organizations by Rogers (2003) for future diffusion studies in construction management research as well as the necessity of developing knowledge concerning implementation.

    Measurement of the nu(mu) energy spectrum with IceCube-792017Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 77, nr 10, artikkel-id 692Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    IceCube is a neutrino observatory deployed in the glacial ice at the geographic South Pole. The nu(mu) energy unfolding described in this paper is based on data taken with IceCube in its 79-string configuration. A sample of muon neutrino charged-current interactions with a purity of 99.5% was selected by means of amultivariate classification process based on machine learning. The subsequent unfolding was performed using the software TRUEE. The resulting spectrum covers an E-nu-range of more than four orders of magnitude from 125 GeV to 3.2 PeV. Compared to the Honda atmospheric neutrino flux model, the energy spectrum shows an excess of more than 1.9 sigma in four adjacent bins for neutrino energies E-nu >= 177.8 TeV. The obtained spectrum is fully compatible with previous measurements of the atmospheric neutrino flux and recent IceCube measurements of a flux of high-energy astrophysical neutrinos.

    Corporate Social Responsibility: The Problem of Securing External Legitimacy in a Globalized World2004Inngår i: 20th EGOS Colloquium July 1-3, 2004 : The Organization as a Set of Dynamic Relationships.  Ljubljana University, Slovenia: Sub-theme 18 : Corporate Social Responsibility, Corporate Citizenship and Politics of Stakeholder Influence, 2004, s. 1-24Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper presents the results from a textual analysis of "Letters from the CEOs" in leading Swedish corporations. The sample consists of letters from annual reports for the years of 1981, 1991 and 2001. The purpose of the paper is to discuss how the textual representations of issues related to corporate social responsibility (CSR) have changed over the period. The results show, not surprisingly, a substantial increase on a number of topics that can be linked to the general CSR-discourse in the 2001 sample. But the rise of a CSR-discourse is related to a drop of another discourse related to social responsibility, in which the CEOs used to comment upon the social, economic and political development of their native country. It is therefore doubtful to claim that business leaders of today feel a larger social responsibility than in the past. In the end section of this paper we discuss the consequences of the shift of responsibilities from a narrower national arena towards a globally dispersed community of stakeholders. It is concluded that the CSR discourse, firmly rooted in a self- regulation philosophy, have not yet emerged as an influential movement in Sweden that affects the overall business conduct in a more substantial manner. The CSR-philosophy seems so far to be a more liberating than restraining factor for those Swedish companies who have moved their operations across the national borders.

    Band Filling Control of the Dzyaloshinskii-Moriya Interaction in Weakly Ferromagnetic Insulators2017Inngår i: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 119, nr 16, artikkel-id 167201Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We observe and explain theoretically a dramatic evolution of the Dzyaloshinskii-Moriya interaction (DMI) in the series of isostructural weak ferromagnets, MnCO3, FeBO3, CoCO3, and NiCO3. The sign of the interaction is encoded in the phase of the x-ray magnetic diffraction amplitude, observed through interference with resonant quadrupole scattering. We find very good quantitative agreement with first-principles electronic structure calculations, reproducing both sign and magnitude through the series, and propose a simplified "toy model" to explain the change in sign with 3d shell filling. The model gives insight into the evolution of the DMI in Mott and charge transfer insulators.

    The suitability of rich learning tasks from a pupil perspective2017Inngår i: CERME 10: Proceedings of the Tenth Congress of European Society for Research in Marhematics Education, European Society for Research in Mathematics Education, 2017, s. 1162-1169Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The construction of tasks is important to challenge pupils, but the exploration of pupils’ perceptions connected to their work with tasks, is rare. This paper presents the results of a study using a tool aimed at measuring pupils’ perception of joy and interest connected to ‘rich learning tasks’ by comparing the views of mathematically promising pupils and others. Two tasks were pre- and postevaluated, the first by 139 and the second by 106 pupils from grade 4-9. The results indicate that the tool is suited for the exploration of pupils’ views, especially as it can be deduced from the comparison that mathematically promising pupils perceived both tasks more positively than the other pupils, and that the non-identified pupils became more positive after working especially with one of the tasks.

    Abstract [en]

    The globalization movement in recent decades has meant a rapid growth of trade, financial transactions and cross-country ownership of economic assets. In this paper, it is examined how the globalization of national business systems has influenced how Corporate Social Responsibility (CSR) is framed. This is achieved through text analysis of CEO letters in major corporations in Sweden under a period of transformational change of the Swedish economy. The results show that the discourse about CSR has changed from a national and communitarian view of responsibility (a negotiated view of CSR) towards an international and individualistic view of responsibility (a self-regulating view of CSR). In the end of the paper it is concluded that this development deserves further scholarly attention.

    A Procedure for Analysing EESD Curricula Applied on Engineering Programmes at Swedish Universities2013Inngår i: Proceedings Engineering Education for Sustainable Development 2013 (EESD13), Cambridge 22-25 September 2013, 2013, s. 389-396, artikkel-id 60Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    There are several different methods for implementing curricular elements, but fairly few procedures for determining the success of the implementation. The central question is whether the student has mastered the desired set of skills and the expertise that fulfil the ambitions of the original policy documents. This paper presents a procedure for analyzing how ambitions related to education for sustainable development (ESD) are implemented in educational programmes, i.e. how political ambitions are cascaded down to the level that the student meets in the courses. The method was applied to the programmes in chemical engineering, mechanical engineering and engineering physics at two Swedish universities. The methodological framework is based on analyses of how ambitions on ESD are handled in texts in relevant documents at different levels and the relation between these. The selected texts were: the national degree ordinance, university policy documents, programme curricula, intended course learning outcomes, and learning assessment texts. While the study is focused on the inclusion of sustainable development competences in engineering education, the presented procedure should be general enough for application to any studied aspect of skills in a programme, in particular when this skill is developed in several different courses. The described procedure can also be used to monitor changes over time.

    Abstract [en]

    This paper reports on comparative research on how textual representations of issues related to corporate social responsibility (CSR) in corporate annual reports from Sweden, Canada and the Netherlands have changed over time. The results show a substantial increase on a number of topics that can be linked to the general CSR-discourse in the 2001 sample in comparison to the 1991 and 1981 samples. The rise in the CSR-discourse appears to be related to a drop in other discourses related to issues of social responsibility regarding the social, economic and political development of a company’s native country.

    Strengthening scaling up through learning from implementation: comparing experiences from Afghanistan, Bangladesh and Uganda2017Inngår i: Health Research Policy and Systems, ISSN 1478-4505, E-ISSN 1478-4505, Vol. 15, artikkel-id 108Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Many effective innovations and interventions are never effectively scaled up. Implementation research (IR) has the promise of supporting scale-up through enabling rapid learning about the intervention and its fit with the context in which it is implemented. We integrate conceptual frameworks addressing different dimensions of scaling up (specifically, the attributes of the service or innovation being scaled, the actors involved, the context, and the scale-up strategy) and questions commonly addressed by IR (concerning acceptability, appropriateness, adoption, feasibility, fidelity to original design, implementation costs, coverage and sustainability) to explore how IR can support scale-up.

    Methods: We draw upon three IR studies conducted by Future Health Systems (FHS) in Afghanistan, Bangladesh and Uganda. We reviewed project documents from the period 2011-2016 to identify information related, to the dimensions of scaling up. Further, for each country, we developed rich descriptions of how the research teams approached scaling up, and how IR contributed to scale-up. The rich descriptions were checked by FHS research teams. We identified common patterns and. differences across the three cases.

    Results: The three cases planned quite different innovations/interventions and had very different types of scale-up strategies. In all three cases, the research teams had extensive prior experience within the study communities, and. little explicit attention was paid, to contextual factors. All three cases involved complex interactions between the research teams and other stakeholders, among stakeholders, and between stakeholders and the intervention. The IR planned by the research teams focussed primarily on feasibility and effectiveness, but in practice, the research teams also had critical insights into other factors such as sustainability, acceptability, cost-effectiveness and appropriateness. Stakeholder analyses and other project management tools further complemented IR.

    Conclusions: IR can provide significant insights into how best to scale-up a particular intervention. To take advantage of insights from IR, scale-up strategies require flexibility and IR must also be sufficiently flexible to respond to new emerging questions. While commonly used conceptual frameworks for scale-up clearly delineate actors, such as implementers, target communities and the support team, in our experience, IR blurred the links between these groups.

    What Do the Things Show us?: Learning as Displacement2016Inngår i: Culture, Biography & Lifelong Learning, ISSN 2384-3527, E-ISSN 2384-3748, Vol. 2, nr 2, s. 17-30Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The question “What do the things show us?” is the prototype of a question in pedagogical contexts, especially in the context of a conventional school lesson. There is supposed to be a definite answer to this question, if the thing in question is distinct and clear, easy to describe.

    However, if there are different concepts of the things in question, or they are difficult to describe, the pole of the object is faced by diverse poles of subjects perceiving one and the same thing differently. Then there is not only one answer to this question. What does this mean for didactics?

    Identification of a novel proinsulin-associated SNP and demonstration that proinsulin is unlikely to be a causal factor in subclinical vascular remodelling using Mendelian randomisation2017Inngår i: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 266, s. 196-204Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and aims: Increased proinsulin relative to insulin levels have been associated with subclinical atherosclerosis (measured by carotid intima-media thickness (cIMT)) and are predictive of future cardiovascular disease (CVD), independently of established risk factors. The mechanisms linking proinsulin to atherosclerosis and CVD are unclear. A genome-wide meta-analysis has identified nine loci associated with circulating proinsulin levels. Using proinsulin-associated SNPs, we set out to use a Mendelian randomisation approach to test the hypothesis that proinsulin plays a causal role in subclinical vascular remodelling.

    Methods: We studied the high CVD-risk IMPROVE cohort (n = 3345), which has detailed biochemical phenotyping and repeated, state-of-the-art, high-resolution carotid ultrasound examinations. Genotyping was performed using Illumina Cardio-Metabo and Immuno arrays, which include reported proinsulin-associated loci. Participants with type 2 diabetes (n = 904) were omitted from the analysis. Linear regression was used to identify proinsulin-associated genetic variants.

    Results: We identified a proinsulin locus on chromosome 15 (rs8029765) and replicated it in data from 20,003 additional individuals. An 11-SNP score, including the previously identified and the chromosome 15 proinsulin-associated loci, was significantly and negatively associated with baseline IMTmean and IMTmax (the primary cIMT phenotypes) but not with progression measures. However, MR-Eggers refuted any significant effect of the proinsulin-associated 11-SNP score, and a non-pleiotropic SNP score of three variants (including rs8029765) demonstrated no effect on baseline or progression cIMT measures.

    Conclusions: We identified a novel proinsulin-associated locus and demonstrated that whilst proinsulin levels are associated with cIMT measures, proinsulin per se is unlikely to have a causative effect on cIMT.

    Postural lung recruitment assessed by lung ultrasound in mechanically ventilated children2017Inngår i: Critical Ultrasound Journal, ISSN 2036-3176, E-ISSN 2036-7902, Vol. 9, artikkel-id 22Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Atelectasis is a common finding in mechanically ventilated children with healthy lungs. This lung collapse cannot be overcome using standard levels of positive end-expiratory pressure (PEEP) and thus for only individualized lung recruitment maneuvers lead to satisfactory therapeutic results. In this short communication, we demonstrate by lung ultrasound images (LUS) the effect of a postural recruitment maneuver (P-RM, i.e., a ventilatory strategy aimed at reaerating atelectasis by changing body position under constant ventilation). Results: Data was collected in the operating room of the Hospital Privado de Comunidad, Mar del Plata, Argentina. Three anesthetized children undergoing mechanical ventilation at constant settings were sequentially subjected to the following two maneuvers: (1) PEEP trial in the supine position PEEP was increased to 10 cmH(2)O for 3 min and then decreased to back to baseline. (2) P-RM patient position was changed from supine to the left and then to the right lateral position for 90 s each before returning to supine. The total P-RM procedure took approximately 3 min. LUS in the supine position showed similar atelectasis before and after the PEEP trial. Contrarily, atelectasis disappeared in the non-dependent lung when patients were placed in the lateral positions. Both lungs remained atelectasis free even after returning to the supine position. Conclusions: We provide LUS images that illustrate the concept and effects of postural recruitment in children. This maneuver has the advantage of achieving recruitment effects without the need to elevate airways pressures.
