    Gay men’s experiences of sexual changes after prostate cancer treatment: a qualitative study in Sweden2019In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, p. 1-5Article in journal (Refereed)
    Abstract [en]

    Background: The needs of gay men after prostate cancer treatment are becoming visible. This patient group reports a more negative impact of treatment than heterosexual men. Yet, gay men’s experiences of post-treatment sexual changes are still little explored. This study aims to determine specific concerns of gay men’s post-treatment sexual practices.

    Methods: A qualitative study design was deployed using semi-structured interviews as data. Participants were purposefully sampled through advertisements and the snowball method. Eleven self-identifying gay men aged 58–81 years and treated for prostate cancer participated in interviews during 2016–2017. The interviews were transcribed, coded and thematically analysed.

    Results: The analysis highlights sexual changes in relation to the physical body, identity and relations. Problematic physical changes included loss of ejaculate and erectile dysfunction. Some respondents reported continued pleasure from anal stimulation and were uncertain about the role of the prostate. These physical changes prompted reflections on age and (dis)ability. Relationship status also impacted perception of physical changes, with temporary sexual contacts demanding more of the men in terms of erection and ejaculations.

    Conclusions: Gay prostate cancer survivors’ narratives about sexual changes circle around similar bodily changes as heterosexual men’s, such as erectile problems and weaker orgasms. The loss of ejaculate was experienced as more debilitating for gay men. Men who had anal sex were concerned about penetration difficulties as well as sensations of anal stimulation. Additional studies are required to better understand the role of the prostate among a diversity of men, regardless of sexuality.

    Embodied: En begreppsanalys och kontextuell utforskning2017Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vad menar vi egentligen när vi säger att vi har det i oss eller att vi ska lära oss med alla våra sinnen och att elever ska utveckla hela sin förmåga? Denna studie är en begreppsanalys av det som man på engelska benämner embodied. Den undersöker detta i en svensk utbildningskontext och försöker finna motsvarande begrepp på svenska. Den belyser hur kroppsligt kunnande/lärande beskrivs inom tre olika utbildningsvetenskapliga områden. Studien består dels av en semantisk undersökning och dels av en kontextuell exploration. Den semantiska undersökningen innehåller en hermeneutisk begreppsanalys enligt Koort (1975) och en etymologisk granskning. Den hermeneutiska explorationen undersöker begreppet embodied först inom praktisk kunskap, sedan inom kognitiva lärandeteorier och slutligen relateras embodied till ett somatiskt kunskapsfält med kroppsliga/body-mind praktiker, på engelska kallat somatics.

    The Power of Business Intelligence on the Decision-Making Process at Linkoping University A Case Study2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The decision-making process (DMP) is based on two elements: Organizational and technical (Poleto et al., 2015). The organizational element is related to managers’ everyday decisionmaking based on the organization strategy (Poleto et al., 2015). Its aim is to set up specific actions for the planned objectives for the business (Rouse, 2018). The second element is the technical DMP. According to (Poleto et al., 2015), it is related the set of tools that are used as an aid in the DMP, which includes information technology and big data. Business intelligence (BI) is the decisionmaking helping system (Ali et al., 2017). Consequently, BI helps make better decisions, and it has become popular in many organizations. As a result, it is important to show BI’s power over DMPs and to show how the tools used in BI facilitate the DMP. “Higher education institutions worldwide are operating today in a very dynamic and complex environment” (Kabakchieva 2015, p. 104). As a result, universities that are within higher education are threatened because competition is serious (Barrett, 2010). Moreover, higher education is another area that will potentially impact big data research (Ong, 2016). Consequently, the application and use of big data in higher educational institutions may result in better quality education for students and a better experience for the university staff (Ong, 2016). As a result, HEI is adopting new technologies with the aim of sustaining its position on the market. DMPs at higher academic institutions require structured data from a sophisticated system, which can be only done through efficient and effective use of BI tools. This thesis will investigate how the BI system is used at Linkoping University (LIU) and how its benefits have changed DMPs. We studied the BI tool (Qlikview) that has been used at LIU for 10 years. 10 To answer the research question, a theoretical framework was developed that was based on two models: Simon’s (1997) and Huber’s (1980) DMP models. The two models were combined with the BI benefits that were based in El Bashir et al.’s (2008) model. The research is done through a qualitative method of data collection and data analysis. At LIU, seven interviews were conducted with BI users and with strategic decision-makers. The findings show that the BI system, alongside Qlikview, has a positive effect on DMPs at LIU as a public HEI. The factors affected are the information gathering time, the quality of data provided and the accessibility to information by all BI users.

    Markov Decision Processes and ARIMA models to analyze and predict Ice Hockey player’s performance2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In this thesis, player’s performance on ice hockey is modelled to create newmetricsby match and season for players. AD-trees have been used to summarize ice hockey matches using state variables, which combine context and action variables to estimate the impact of each action under that specific state using Markov Decision Processes. With that, an impact measure has been described and four player metrics have been derived by match for regular seasons 2007-2008 and 2008-2009. General analysis has been performed for these metrics and ARIMA models have been used to analyze and predict players performance. The best prediction achieved in the modelling is the mean of the previous matches. The combination of several metrics including the ones created in this thesis could be combined to evaluate player’s performance using salary ranges to indicate whether a player is worth hiring/maintaining/firing

    An LLVM backend for the Open Modelica Compiler2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This thesis presents the construction and evaluation of an LLVM based codegenerator, an LLVM backend. The introduction of an LLVM based backend into the OpenModelica compiler was done to examine the advantages and disadvantages of compiling Modelica and MetaModelica to LLVM IR instead of C. To answer this question, the LLVM backend was compared against the existing interpreter and C code generator using four different schemes with corresponding cases. This comparison was made both for both optimised and unoptimised code. From the experiments, it was concluded that an LLVM backend can be used to improve runtime and compile time performance in the OpenModelica Interactive environment.

    Strukturella förändringar i Östergötlands skogar: En jämförelse mellan år 1927 och 1983–20172018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Humans have affected the Swedish forests for a long time, mainly through agriculture and forestry. Since the beginning of the 20th century, a lot of changes have taken place in forest policy, which have affected the structures of our forests, such as tree age, size and species distributions. By using information from different types of historical data, we can increase our understanding of the earlier structures of forests and how to manage them in the future. This study investigated changes in annual growth and changes in age, diameter, height and tree species distribution in the forests of Östergötland from year 1927 to the period 1983-2017, using data from the Swedish National Forest Inventory. Six tree species where used, Picea spp, Pinus spp, Quercus robur, Betula spp, Alnus spp and Populus tremula. There was an increase in the proportion of Picea spp, and a decrease in the proportion of Pinus spp since 1927. The proportion of deciduous trees also increased but not as much. Interestingly, the proportion of Betula spp had fallen since 1927, but the now larger proportion of young trees indicate that the proportion of Betula spp is increasing again. Q. robur, P. tremula, Picea spp and Pinus spp also had a larger proportion of younger trees in the more recent period. There was a significantly higher proportion of tall trees during the latter period for all tree species. For growth rate in width, the results varied among tree species. For Betula spp it had decreased and for Q. robur it had increased. For the coniferous trees there was hardly any difference between the periods. Overall, the results show that Östergötland's forests have been influenced by forestry and increased ungulate populations since the first inventory 1927 and that there have been changes in the composition of the forests.

    Efficient Energy Use of FPGA for Underwater Sensor Network2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Operational time is becoming an increasingly important aspect in electronic devices and is also highly relevant in Underwater Acoustic Sensor Networks (UWSN). This thesis contains a study which explores what can be done to de-crease power consumption while maintaining the same functionality of an FPGA inside an underwater sensor-node network. A longer operational time means a more effective system since reconnaissance is one of UWSN’s area of application. The thesis will also cover the implementation of a new sensor-node ‘mode’ which will add new features and increase operational time.

    Lokalt utvecklings- och tillväxtarbete: En studie av kommunernas näringslivsfunktioner2019Report (Other academic)
    Abstract [sv]

    Denna rapport handlar om hur kommunerna arbetar med utvecklings- och tillväxtarbete. Förväntningarna på att kommuner ska verka för lokalt utvecklingsarbete har inneburit växande åtaganden för den kommunala sektorn. Genom rapporten redovisas och analyseras resultaten från en enkätstudie som riktade sig till näringslivsanvariga tjänstepersoner i samtliga kommuner i Sverige. Genom enkäten ställdes frågor om vad kommunerna i Sverige gör inom området utvecklings- och tillväxtarbete och på vilket sätt resurser för det här området genereras genom externa relationer med andra kommuner, regionala organ, EU samt statliga organisationer. Resultatet från enkätstudien redovisas dels för alla kommuner som besvarat enkäten (62 procent av Sveriges kommuner) sammantaget och dels uppdelat på olika kommunkategorier. Denna kategorisering utgår från SKLs kommungruppsindelning.

    Den sammanfattande diskussionen utgår från tre slutsatser. För det första kvarstår det som kan betraktas vara det traditionella området för kommunernas tillväxtarbete – som centreras kring kontaktskapande arbete med lokala nätverk, organisationer och företag – som ett centralt moment för kommunernas lokala tillväxtarbete. Detta område benämner vi näringslivsarbete och det omfattar att främja sektorsövergripande kommunikation mellan kommunen och de lokala företagen. Detta område omfattar även att arbeta med platsmarknadsföring.

    För det andra har synen på vad utvecklings- och tillväxtarbete omfattar breddats. Detta ställer krav på samverkan över traditionella gränser inom kommunens förvaltning. Enkätresultatetet visar erfarenheter av att arbetet genom kommunernas näringslivsfunktion innebär att bli involverad för frågor om fysisk planering och för kompetensutveckling. Tidigare studier och den genomförda enkäten illustrerar att kommunernas utvecklings- och tillväxtarbete har kommit att breddats till att relatera till samtliga delar av hållbar utveckling. Samtidigt framträdet frågor om ekonomisk hållbarhet och fysisk planering mer tydligt än frågor om social hållbarhet, genom exempelvis arbetsmarknadsfrågor, och ekologiskt hållbarhet, genom exempelvis samverkan med miljönätverk.

    Slutsats nummer tre handlar om hur tillväxtarbete sker på olika sätt i olika geografier. Enkätstudien visar att kommunkategorier som i högre grad är beroende av sina egna lokala arbetsmarknader (dvs. större städer, mindre städer och landsbygdskommuner) är mer aktiva inom det lokala tillväxtarbetet jämfört med utpendlingskommuner, samtidigt som profilen för det här arbetet skiljer sig åt mellan de tre kategorier av kommuner som är mest aktiva.

    För att värdera resultatet som framkommer genom studien som presenteras och diskuteras i den här rapporten är det också viktigt att påminna om begränsningarna. Det empiriska materialet har genererats genom en enkätstudie som riktade sig till tjänstepersoner i ledningen för kommunernas näringslivsfunktioner. Det betyder att resultatet har genererats utifrån hur en respondent per kommun har besvarat frågor om det breda fält lokalt utvecklingsarbete berör. Studiens design har syftat till att ge en översikt som genererar frågor för fördjupade studier. Ett angeläget tema för framtida studier är frågan om geografiska beroendeförhållanden för det lokala utvecklingsarbetet och som innebär att fördjupa förståelsen för varierande förutsättningar för kommunernas utvecklingsarbete och hur detta skapar villkor för samverkan med andra politiska nivåer och andra kommuner. Jämförelser mellan olika kommunkategorier visar att kommunernas samverkan ser olika ut och att profilen för det lokala utvecklingsarbetet varierar.

    Scheduling of Electric Buses with Column Generation2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Column generation has during the last years been popular in vehicle scheduling as it for larger problems can find an optimum faster than using an ordinary mixed-integer programming (MIP) model. We study the problem of finding optimal schedules for electric buses by means of column generation. The motive for this approach is that when the size of the problem becomes very large in terms of variables and different solutions, solving it with a mixed- integer programming model can take a lot time. The purpose of this work is to investigate how the best found integral solution and the solution time vary between different column generation methods and how these methods perform compared to a MIP. This has been done by implementing these methods on a test problem for scheduling of electric buses. The results indicate that column generation methods can be very efficient in terms of time and best found integral solution for larger problems. A modified column generation method has been created in order to accelerate the generation of columns, which is better than standard column generation in terms of solution time and best found integral solution.

    State of the Art of Design Methods for Resource Efficient and Effective Solutions: Report from “Product and Service Design Methods for REES” Project of Mistra REES program2017Report (Other academic)
    Abstract [en]

    This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Methods for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design methods and deriving requirements for design methods, respectively. The document only covers results from the scientific literature review, while other reports to be developed will cover results, for instance, from the interview study and the design session with industry partners in the Mistra REES consortium. The results of the literature review will be a foundation for WP 2.3, which aims at developing new design methods. Note that methods here include frameworks, tools, and support for designers.

    The document describes current use (i.e., “as‐is” status) of product and service design methods when designing REES, as well as requirements for product and service design methods for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.

    From the overall analysis, found is a lack of insights about methods for designing REES, although potentially useful methods are available. This means advancement of knowledge is insufficient for industry within the subject, which is relatively new. It may also mean the developed methods are not precisely according to the needs of companies. This shows a high potential of developing new methods in the rest of the project.

    More specifically, in the requirement specification, the literature shows that potentially useful methods include QFD (Quality Function Deployment), the Taguchi method, the Kano model, and data mining, among others. In the conceptual design, numerous methods exist, and most of them were developed in an older context, where REES was not as relevant as today. Those methods include DfX methods (X denotes cost, assembly, etc.), the functional block diagram, the checklist, morphological analysis, and the Fishbone Diagram. Only a few seem to be used widely in industry today. In the analysis and evaluation, available methods include Lifecycle Simulation, Lifecycle Costing, multi‐criteria decision making, and the Analytical Hierarchy Process. Most of the methods or tools available specialise in one area. This is a problem when developing an integrated offering of products and services, because designers need to have a holistic perspective for that.

    Regarding requirements for methods to be developed, the authors analysed literature as follows. In the requirement specification, requirements originating from multiple aspects and actors need to be taken into account. Since an enormous amount of data and information can be collected from products and by technologies implemented today, a huge opportunity is presented for enhancing requirement specification. Yet, there seems to be little insights to take this opportunity. In conceptual design, it is important to identify and involve relevant actors as well as their requirements according to a number of scientific reports. Especially, interaction between the relevant actors seems to be critical to be implemented. In analysis and evaluation, various pieces of earlier research works recommend different features to be implemented in methods. These features include visualization of information and information flows, graphical user interface, multiple users’ participation, and ability to handle environmental information, uncertainty and risk.

    Support for Designing Resource Efficient and Effective Solutions: Current Use and Requirements by Swedish Industry: Report from “Product and Service Design Support for REES” Project of Mistra REES program2017Report (Other academic)
    Abstract [en]

    This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Support for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design support and deriving requirements for design support, respectively. The document only covers results from interviews with companies, while the other reports will cover results, for instance, from scientific literature review (ISRN: LIU‐IEI‐RR‐‐17/00264—SE) and the design session with industry partners in the Mistra REES consortium. The results of this research into industrial practice will be a foundation for WP 2.3, which aims at developing new design support for designers.

    The document describes current use (i.e., “as‐is” status) of product and service design support when designing REES, as well as requirements for product and service design support for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.

    Eight Sweden‐based companies that provide products and services in different sectors and work on resource efficiency participated in the interviews. They vary in terms of the size: from small to large. 24 individual interviews were conducted in total with the length being between 54 and 117 minutes (with two additional shorter follow up interviews via phone/skype). The 24 interviews were carried out all with face to face between May and July, 2016. The result from each company is described per section in this report, while cross‐company analysis will be made in a separate document.

    Relevance feedback-based optimization of search queries for Patents2019Independent thesis Advanced level (degree of Master (Two Years)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    In this project, we design a search query optimization system based on the user’s relevance feedback by generating customized query strings for existing patent alerts. Firstly, the Rocchio algorithm is used to generate a search string by analyzing the characteristics of related patents and unrelated patents. Then the collaborative filtering recommendation algorithm is used to rank the query results, which considering the previous relevance feedback and patent features, instead of only considering the similarity between query and patents as the traditional method.

    In order to further explore the performance of the optimization system, we design and conduct a series of evaluation experiments regarding TF-IDF as a baseline method. Experiments show that, with the use of generated search strings, the proportion of unrelated patents in search results is significantly reduced over time. In 4 months, the precision of the retrieved results is optimized from 53.5% to 72%. What’s more, the rank performance of the method we proposed is better than the baseline method. In terms of precision, top10 of recommendation algorithm is about 5 percentage points higher than the baseline method, and top20 is about 7.5% higher. It can be concluded that the approach we proposed can effectively optimize patent search results by learning relevance feedback.

    Comparison of Auto-Scaling Policies Using Docker Swarm2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    When deploying software engineering applications in the cloud there are two similar software components used. These are Virtual Machines and Containers. In recent years containers have seen an increase in popularity and usage, in part because of tools such as Docker and Kubernetes. Virtual Machines (VM) have also seen an increase in usage as more companies move to solutions in the cloud with services like Amazon Web Services, Google Compute Engine, Microsoft Azure and DigitalOcean. There are also some solutions using auto-scaling, a technique where VMs are commisioned and deployed to as load increases in order to increase application performace. As the application load decreases VMs are decommisioned to reduce costs.

    In this thesis we implement and evaluate auto-scaling policies that use both Virtual Machines and Containers. We compare four different policies, including two baseline policies. For the non-baseline policies we define a policy where we use a single Container for every Virtual Machine and a policy where we use several Containers per Virtual Machine. To compare the policies we deploy an image serving application and run workloads to test them. We find that the choice of deployment strategy and policy matters for response time and error rate. We also find that deploying applications as described in the methodis estimated to take roughly 2 to 3 minutes.

    Hur unga vuxna som tagit del av arbetsinriktade insatser upplever övergången från skola till arbete: Behov av stöd i övergången2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Övergången från skola till arbete eller vidare studier för unga vuxna är en enskild aktivitetsperiod som formas av en interaktion mellan individen och den omgivande miljön. Övergången präglas av strävan efter ett arbete men att få en fast förankring på den reguljära arbetsmarknaden kan vara problematisk. Unga vuxna kan därför vara i behov av stöd från samhällets resurser samt familj och vänner. Syftet med studien är att beskriva hur unga vuxna upplever övergången från skola till arbete eller vidare studier samt om unga vuxna upplever behov av stöd i övergången från skola till arbete eller vidare studier och i sådana fall vilken typ av stöd. För att besvara studiens syfte intervjuades åtta personer i åldrarna 19 till 28 år som upplevde en pågående övergång. Intervjuguiden har Model of Human Occupation samt Bolic Baric som teoretisk förankring. Det inspelande materialet har transkriberats, analyserat och kondenserats. I resultatet framkom övergången som en tid av förändrade rutiner och roller där unga vuxna formas efter samhället. I övergången är stöd från familj och vänner samt samhället nödvändigt men upplevs varierat. Det finns ett behov av vidare forskning gällande utformning och implementering av insatser då övergången är en komplex tid som utvecklas fortskridande.

    Denna litteraturstudie diskuterar och analyserar forskning om mångkultur i klassrummen. Undersökningen ämnar skapa förståelse kring vilka skillnader som kan finnas i undervisningen beroende på om den genomförs i ett homogent eller mångkulturellt klassrum. Genom att förstå eventuella skillnader kan man motverka dem och då ge alla elever likvärdig chans till utbildning och därigenom skapa ett mer jämlikt samhälle. Arbetets koppling till jämställdhet och demokratiska värderingar gör att vi kopplar det till den samhällsvetenskapliga ämnesdidaktiken. Vi har i studien utgått från tre frågeställningar: Hur påverkas undervisningen av mångkulturalitet? Vilka anpassningar krävs av läraren i ett mångkulturellt klassrum? samt Skiljer sig vårdnadshavares förväntningar på läraren åt mellan ett mångkulturellt och ett homogent klassrum? Forskningen vi utgått från är referee-granskad och samlades in genom en systematisk litteratursökning via databaser och manuella sökningar. Resultatet visar att lärare i det mångkulturella klassrummet idag får en större pedagogisk utmaning. Detta anser vi kräver specificerade lärarutbildningar, som idag inte finns, för att alla elever ska få det stöd och de anpassningar de behöver. I vår forskningsanalys framkom även att mångkulturalitet i skolan av samhället framför allt ses som något negativt men till största delen är till fördel för alla elever, oavsett kulturell bakgrund. Att undervisa mångkulturellt anser vi skapa inkluderande individer som gemensamt bildar till ett jämlikt samhälle med mindre segregation.

    EU burden-sharing in the Refugee Crisis: A Strategic Game Perspective2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Recent developments in migration filed within EU showed problematic character of EU member states co-operation in face of migration burden-sharing.

    Migration crisis of 2015-2016 shed a light on migration burden-sharing and made subject one of the most discussed issues in European Union. There is a continues flow of migrants who want to enter and lodge their application for protection in EU states. Therefore EU boarder states are often faced with overwhelming number of migrants, number that exceeds their receiving capacity. Consequently there is need for migration burden-sharing. But, since reception of asylum seekers is connected to costs and is overall politically sensitive subject we see limited migration burden-sharing practiced by EU member states. This project analyses member states behaviour from game theoretical viewpoint applying non-cooperational game model Prisoner’s Dilemma to problematic burden-sharing practices within EU. Aim of the paper is to find out if game theory is a sufficient basis for explaining and understanding member state behavior in regards of migration burden-sharing, on the background of migration crisis 2015-2016. It even examines hypothesis regarding weather EU provides member states with sufficient settings for practicing migration burden-sharing.

    Sensor interpixel correlation analysis and reduction for color filter array high dynamic range image reconstruction2019In: Color Research and Application, ISSN 0361-2317, E-ISSN 1520-6378, p. 1-13, article id 22343Article in journal (Refereed)
    Abstract [en]

    High dynamic range imaging (HDRI) by bracketing of low dynamic range (LDR) images is demanding, as the sensor is deliberately operated at saturation. This exacerbates any crosstalk, interpixel capacitance, blooming and smear, all causing interpixel correlations (IC) and a deteriorated modulation transfer function (MTF). Established HDRI algorithms exclude saturated pixels, but generally overlook IC. This work presents a calibration method to estimate the affected region from saturated pixels for a color filter array (CFA) sensor, using the native CFA as a matched filter. The method minimizes color crosstalk given a set of candidates for proximity regions, and requires no special setup. Results are shown for a 21-bit HDR output image with improved color fidelity and reduced noise. The calibration reduces IC in the LDR images and is performed only once for a given sensor. The improvement is applicable to any HDRI algorithm based on CFA image bracketing, irrespective of sensor technology. Generalizations to subsaturated and supersaturated pixels are described, facilitating a suggested irradiance-exposure dependent point spread function charge repatriation strategy.

    “A freak that no one can love”: Difficult knowledge in testimonials on school bullying2019In: Research Papers in Education, ISSN 0267-1522, E-ISSN 1470-1146, p. 1-19Article in journal (Refereed)
    Abstract [en]

    This study adopts a testimonial approach to bullying victimisation,and aims to create a deeper understanding of the experiences andeffects of being a bullying target. Four written narratives about beingsubjected to school bullying were analysed according to interpretativephenomenological analysis. From the analysis, four themes wereconstructed, which represented different elements of victimhood: (1)Self-blame in which victims view themselves as the cause of thebullying, (2) Abandonment in which victims describe feelings ofstanding alone in their exposed situation, (3) Turning points inwhich the victims recount a variety of restorative events, and (4)Continued victimhood in which the victims relate how the feeling ofvictimhood and vulnerability continues even though the bullying hasended. In conclusion, school bullying is something that continues toaffect the individual adversely long after it has stopped, althoughstable friendship relations might have a mitigating influence.Through such relations, victimhood can be neutralised and a morepositive self-image develop. Moreover, as numerous other kinds ofvictims emphasise, an essential part of the rehabilitation process is tofinally be able to tell one’s story, to lay bare one’s difficult knowledgeto a wider audience.

    Kommuner som forskningspolitiska aktörer: En jämförelse mellan Norrköping och Örebro2018Report (Other academic)
    Abstract [sv]

    De svenska kommunerna har blivit allt mer aktiva som forskningspolitiska aktörer. Kommunerna samverkar allt mer med forskare och forskningsmiljöer på universitet och högskolor, och fungerar i ökad utsträckning också som finansiärer av universitetsforskning. Flera offentliga verksamheter har decentraliserats till kommunerna vilket ökat kraven och förväntningarna på lokal kunskapsutveckling. Kunskapen om kommuner som forskningspolitiska aktörer är dock ytterst begränsad. Få studier har ägnats åt att beskriva och analysera de svenska kommunernas forskningspolitiska strategier, vilka faktorer som påverkar kommunernas forskningspolitik och vilka konsekvenser den får för det forskningspolitiska systemet i sin helhet. Eftersom flera omständigheter tyder på att kommunal forskningspolitik kan möta utmaningar som skiljer sig från den nationella politikens, t.ex. genom att man riskerar att styras av sitt beroende av ett lokalt lärosäte eller att man har en svag institutionell kapacitet att hantera relationen till forskare och lärosäten, finns det skäl att granska och analysera kommunernas roll som forskningspolitiska aktörer.

    I denna rapport redovisas resultatet om en jämförande fallstudie av forskningspolitik i två kommuner: Norrköping och Örebro. Huvudsyftet med studien är att beskriva och analysera kommunernas forskningspolitiska strategier. Fokus ligger på att undersöka kommunernas vilja och förmåga att göra prioriteringar, mobilisera finansiella resurser och bygga upp organisatoriska arrangemang inom forskningspolitiken. I studien analyseras särskilt huruvida kommunernas strategier präglas av långsiktighet och kontinuitet eller av tillfälliga satsningar och ad-hoc lösningar. I studien diskuteras också olika förklaringar till likheter och olikheter i forskningspolitikens utformning i de båda kommunerna. Ambitionen med studien är att bidra med ny kunskap om kommuner som forskningspolitiska aktörer och om hur kommunerna tolkar sitt handlingsutrymme i förhållande till staten och lagstiftningen inom detta område. Studien bygger på analyser av skriftliga dokument, tidigare studier och intervjuer.

    Studien visar att båda de studerade kommunerna har engagerat sig i forskningspolitiska frågor och tagit olika initiativ för att stödja forskning. Men kommunernas strategier har sett olika ut. Norrköpings kommun har lagt förhållandevis stora resurser på forskning och utvecklingsverksamhet och varit en aktiv samarbetspartner till universitetet. Kommunens arbete har varit långsiktigt och präglats av en stark kontinuitet. Politiken har kommit till uttryck i olika former av avtal om finansiering och samverkan med universitetet, men också i olika organisatoriska strukturer för fördelning av forskningsmedel. I Örebro kommun har forskningspolitiken inte präglats av samma kontinuitet och långsiktighet. De politiska partierna har här varit mer oense om vilken inriktning politiken ska ha och vilket handlingsutrymme som man anser att kommunen har på området. Politiken har i Örebro främst tagit sig uttryck i ett antal specifika satsningar på det lokala lärosätets forskning, inte minst för att kompensera för frånvaron av statliga medel, men det finns få exempel på mer långsiktiga engagemang. Relationen mellan kommunen och universitetet, åtminstone när det gäller forskningsfrågor, har varit mindre tät och utvecklad i Örebro i jämförelse med hur det sett ut i Norrköpings kommun. Varken i Norrköping eller i Örebro har kommunen byggt upp någon stark organisation för att mer strategiskt hantera FoU-frågor.

    Vilka faktorer kan då förklara kommunernas forskningspolitik? I rapporten diskuteras denna fråga med utgångspunkt från tre övergripande faktorer: 1) statlig politik och reglering, 2) den lokala kunskapsproduktionens struktur samt 3) lokal politik och lokala maktstrukturer. Statlig politik och reglering har varit viktiga förutsättningar för kommunernas olika initiativ. I synnerhet har den statliga högskolepolitiken spelat en central roll för kommunernas vilja att och intresse för att engagera sig i forskningspolitik. Etableringen av campuset i Norrköping och högskolans uppgradering till universitet i Örebro har på många sätt varit viktiga skäl till kommunernas satsningar. Liksom inom näringslivspolitiken kan vi konstatera att kommunernas handlingsutrymme inom detta området är ganska stort, och att statens inställning till kommunal forskningspolitik i allt väsentligt varit positiv. Kommunerna har varit angelägna om att motivera olika satsningar i förhållande till medborgarnas behov, vilket ju också betonas i kommunallagen.

    Den lokala kunskapsproduktionens struktur har påverkat incitamenten för kommunerna att ta forskningspolitiska initiativ. I Norrköpings kommun, där det finns ett universitetscampus men där universitetets huvudcampus finns i en annan kommun, har det funnits starka incitament för kommunen att satsa på forskning för att stärka det egna campuset. I Örebro kommun har inte beroendet av universitetet (tidigare högskolan) uppfattats som lika starkt som i Norrköping. Örebro kommun har inte, som Norrköping, behövt konkurrera med en näraliggande kommun om utbildningsplatser och forskningsresurser eftersom universitetet huvudsakligen haft sin verksamhet inom den egna kommunens gränser. Detta förefaller vara en viktig faktor för att förklara skillnader mellan kommunernas forskningspolitik.

    Kommunernas forskningspolitik har utgått ifrån delvis olika politiska mål. Politikens inriktning är också uttryck för olika maktstrukturer och socioekonomiska förutsättningar i kommunerna. I Norrköping har många av satsningarna vägletts av en stark politisk vilja att hantera den låga utbildningsnivån och höga arbetslösheten i kommunen. De initiativ som tagits har ofta växt fram inom ramen för samverkansstrukturer där olika samhällsintressen (inte minst näringslivet) varit företrädda och beslut har oftast tagits i partipolitisk enighet. I Örebro kommun har satsningarna skett i mer direkt samverkan mellan kommun och högskola/universitet. Framväxten av initiativ har oftast inte skett i sammanhang där olika samhällsintressen varit direkt företrädda. De större satsningarna har varit tätare knutna till kommunens egna uppdrag eller den övergripande regionala utvecklingen. I Örebro har också partipolitik spelat en större roll för inriktningen på forskningspolitiken.

    Sammanfattningsvis har denna undersökning bidragit med ny kunskap om kommuner som forskningspolitiska aktörer. Den huvudsakliga ambitionen har varit att beskriva, jämföra och förklara forskningspolitiken i två kommuner. Men studiens resultat kan också bidra till att förstå andra liknande fall och bidra till teorier om hur lokal forskningspolitik kan förstås och förklaras. Studien väcker vidare nya frågor som behöver fördjupas i kommande studier. Vilken betydelse har t.ex. kommuners forskningspolitik haft för forskningen på universitet och högskolor? Har kommunernas initiativ kompletterat statliga initiativ eller t.o.m. bidragit till framväxten av nya forskningsområden? Mer forskning behövs om kommunernas forskningspolitik och dess roll i det svenska forskningslandskapet.

    A stable, high order accurate and efficient hybrid method for flow calculations in complex geometries2018In: 2018 AIAA Aerospace Sciences Meeting, AIAA SciTech Forum, (AIAA 2018-1096), American Institute of Aeronautics and Astronautics, 2018, no 210059, p. 1-9Conference paper (Refereed)
    Abstract [en]

    The suitability of a discretization method is highly dependent on the shape of the domain. Finite difference schemes are typically efficient, but struggle with complex geometry, while finite element methods are expensive but well suited for complex geometries. In this paper we propose a provably stable hybrid method for a 2D advection–diffusion problem, using a class of inner product compatible projection operators to couple the non-conforming grids that arise due to varying the discretization method throughout the domain.

    Barriärer på en vårdcentral: Utmaningar inom vården i segregerade områden2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this paper is to investigate and analyze which communication barriers exist in health centers in segregated areas in Sweden, and how to handle these barriers. I have asked two questions: Which communication barriers are there in a health center in a segregated area? How does healthcare staff handle communication barriers? 

    The work is based on the qualitative field study that I have carried out at two health centers located in segregated areas in Sweden. I have made both observations and participatory observations and held both informal and semi-structured conversations with several employees at both health centers to collect data.

    In the result, I process the use of an interpreter and the five different barriers that I have identified: the language barrier, the knowledge barrier, the barrier of understanding, the culture barrier and the barrier of experience. The result shows that the barriers manifest themselves in many different ways and that the staff often needs to be creative in its way of handling them. It is common for the recipients to not speak and / or understand Swedish and to not have knowledge of the Swedish healthcare system or what a health center is. It is also common that they lack or have insufficient knowledge of the human body, diseases and treatments. Interpreters work well as intermediaries who can enhance communication and reduce the risk of misunderstanding, but the use of an interpreter can also be difficult, and it can be difficult to get access to a good interpreter on time. The communication barriers that arise increase the risk of misunderstandings and mistrust which can lead to a deterioration in care quality. Misunderstandings can lead to the recipient not being able to follow the treatment plan as intended, and mistrust can lead to the recipient choosing to abstain wholly or partly from treatment. 

    To prevent this, the staff is careful to take extra time to explain, discuss and listen to the patient. The work on trust is very important as a bad meeting can lead to negative attitudes in large groups of people towards the health center. This is because many of the recipients are part of a very strong personal sector, which has a great influence on how health care and treatments are perceived. A good meeting can lead to major changes and therefore the health centers work extra hard to create good experiences for the health care recipients.

    Struktur, konkurrenskraft och utveckling i snickerisegment2019Report (Other academic)
    Abstract [sv]

    Det samlade värdet av sågverks-, trämanufaktur- och möbelindustrin – trävärdekedjan – uppgick år 2017 till drygt 100 Mdr SEK för företag med fler än 9 anställda. En kraftig tillväxt följde innan omvärldsfaktorer som finanskris, minskat bostadsbyggande, valutaoro och så vidare bromsade in utvecklingen. Under de efterföljande åren har värdekedjan återhämtat sig delvis tack vare en ökad klimat- och miljödebatt som gynnat ett förnybart material. År 2017 omsatte värdekedjan knappa 90 Mdr SEK.

    I projektet ”E-handelns påverkan på snickeriindustrin” har ingått att beskriva ett antal delbranscher inom trävärdekedjan och analysera vilka hot och möjligheter som dessa branscher har stått inför. Ingående delbranscher är dörrar, fönster, trappor, men ytterligare närliggande delbranscher har valts att redovisa i denna rapport. Beskrivningen bygger på ekonomiska data insamlade via företagens årsredovisningar för perioden 2008 till 2017, på branschstudier som visar respektive bransch samt generella konjunkturella studier för den svenska marknaden.

    Bilden som framträder är branscher som mår förhållandevis bra. Omsättningsökning, måttligt god lönsamhet och tillväxt. Det finns dock orosmoln som tornar upp sig, där mindre företag uppvisar en sämre lönsamhet, konkurrensen från utlandet och mer standardiserade produkter kommer in, samt att mellanleden har en fortsatt stark roll i värdekedjan.

    Framtidsutsikterna ser generellt positiva ut, och analysen kan delvis påvisa vikten av fortsatt nära relation med slutkunder, vikten av att hitta unika produkter som kan modulariseras och snabbt utvecklas vidare, och att noggrant följa hur näthandeln utvecklar sig.

    Logistik för ökad svensk konkurrenskraft: Forsknings- och innovationsagenda för framtidens logistik2013Report (Other academic)
    Abstract [sv]

    Framtidens logistik står inför mycket stora utmaningar som har direkt bäring på svenska företags och organisationers förmåga till tillväxt, hållbarhet och konkurrenskraft. 

    Det står utom all tvivel att logistikens betydelse kommer att öka ännu mer i framtiden. Vinnare på de globala, rörliga marknaderna kommer ett vara de flödeseffektiva företagen, som har förmåga att hantera förändringarna på marknaden med en effektiv logistik som grund. För att lyckas behövs ett Logistiklyft för Sverige, med ett medvetet fokus på att utveckla de dynamiska förmågorna i företag och organisationer. Detta gäller i de allra flesta branscher och typ av företag.

    Den här innovations- och forskningsagendan utgår från den svenska traditionen och internationellt sett unika kunskapen och förmågan att med en systemsyn som grund designa, utveckla och styra komplexa system där flera olika kompetenser samverkar. Logistikens systemkunskap handlar om att lära sig att utforma och styra omfattande och allt mer komplexa försörjningskedjor (supply chains) från råvara till slutkund i syfte att öka svenska företags internationella konkurrenskraft och förmåga att växa på ett miljömässigt och ekonomiskt hållbart sätt

    Agendan adresserar behovet av kompetens och kunskap för mer innovativ logistikutveckling som följer:

    • Utveckling av kunskap om nya och mer innovativa logistiksystem och modeller för industri & handel 
    • Tjänsteutveckling för transport/logistik och IT-företag som stöd för mer innovativa logistiksystem, men också att ta till vara och stimulera den omfattande tjänsteutveckling som finns i förnyelsen av svenskt näringsliv, t ex mot högre grad av e-handel. 
    • Tillämpning av befintliga logistikkunskaper för områden och sektorer i behov av ett logistiklyft och ökad flödeseffektivitet, t.ex. logistik för små- och medelstora företag (SME) med fokus på HUR (genomförandeprocesser) istället för VAD (utformning av koncept och modeller). 
    • Utveckling av kunskaper om hur logistiksystem kan bidra till en hållbar utveckling, såväl miljömässigt som socialt.
    • Utveckling av kunskap om och tillämpning av logistiklösningar med primär samhällsnytta, t ex sjukvårdslogistik och citylogistik samt effektiv och hållbar försörjning av livsmedel, energi etc.

    Den här forsknigs- och innovationsagendan är utvecklad i samarbete mellan Linköpings Universitet, Lunds Tekniska Högskola, Chalmers Tekniska Högskola och en lång rad företag där Axis, SKF, Volvo och Nobel Biocare har funnits med i projektets styrgrupp.

    Patients' experiences of how symptoms are explained and influences on back-related health after pre-surgery physiotherapy: A qualitative study2019In: Musculoskeletal science & practice, ISSN 2468-7812, Vol. 40, p. 34-39Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Since the pre-surgery phase is a new setting for physiotherapy, exploring patients' experiences might contribute to new insights for future development of care in patients with degenerative lumbar spine disorders.

    OBJECTIVES: To describe patients' experiences of how symptoms are explained, and their experiences of the influences on back-related health after pre-surgery physiotherapy.

    DESIGN: Explorative qualitative design using semi-structured interviews analysed with content analysis.

    PARTICIPANTS: Eighteen patients with degenerative lumbar spine disorder scheduled for surgery, participated in pre-surgery physiotherapy.

    FINDINGS: Five categories were identified: Influences on symptoms, physical function and sleep; Influences on coping and well-being; Explanations of back-related symptoms and wanting to be well-informed; Influence on social functioning; The ability of the model of care to influence reassurance and prevention.

    CONCLUSION: Improvements in back-related health in all the biopsychosocial dimensions emerged. Even those who expressed no symptom improvements, felt better performing exercises than being inactive, and exercises improved their frame of mind, a useful experience in possible low back pain recurrences. Pre-surgery physiotherapy provided reassurance and gave time to reflect on treatments and lifestyle. Despite pre-surgery physiotherapy, back-related symptoms were mainly described in line with a biomedical explanatory model. Those using broader explanations were confident that physiotherapy and self-management could influence their symptoms. Suggesting more emphasis on explanatory models suitable for surgery, pre- and post-surgery physiotherapy and self-management in the professionals' dialogue with patients.

    Matematikundervisning utomhus: En litteraturstudie om hur utomhuspedagogik används för elevers lärande i matematik2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med detta konsumtionsarbete var att undersöka hur utomhuspedagogik används i matematikundervisning. Denna undersökning har genomförts genom att samla in, granska och bearbeta utvald litteratur för att försöka besvara arbetets syfte. Insamling av data genom vetenskapliga artiklar gjordes med hjälp av databaserna ERIC och UniSearch. Resultatet av litteraturstudien visar på två exempel på hur utomhuspedagogik kan användas i matematikundervisning. Det första är hur lärare använder digital teknik som verktyg för att tillämpa metoder och koppla undervisningen med vardagliga situationer. Det andra visar att utomhuspedagogik i matematikundervisning kan användas för att motivera elever och stötta kunskapsutvecklingen.

    Framgångrika digitala verktyg för matematikundervisning där problemlösning är i centrum: En litteraturstudie med fokus på tidigare åldrar2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna litteraturstudie var att undersöka forskning om hur olika typer av digitala verktyg används i matematikundervisning en riktat mot problemlösning, som undervisningsinnehåll. Fokuset riktar sig i första hand mot undervisning för elever i åk 4–6, men kan även gälla tidigare och senare årskurser. De digitala verktygen som har behandlats är iPads, appar med resurser, datorer, IKT, digitala spel och flipped classroom (omvänt klassrum). Litteraturstudiens syfte och innehåll är relevant då digitala verktyg har blivit allt vanligare i skolans värld. Insamlingen av data skedde genom användning av databaserna UniSearch och ERIC. Resultatet från tio vetenskapliga artiklar visade att användning av digitala verktyg i matematikundervisning kan stödja och bidra till ut vecklingen av elevers matematiska problemlösningsförmåga. Det framkom även i resultatet att det finns nackdelar med användning av digitala verktyg i matematikundervisning under en längre period.

    Abstract [en]

    There is a pronounced need within Swedish government agencies to find approaches for quantifying greenhouse gases, as part of their work towards the goal of becoming role models in environmental management. Approaches that are practically feasible, useful and meet the government agencies needs and wishes. This study aims to identify and compare different approaches to quantitatively assessing greenhouse gas emissions. There are different international established approaches, and this thesis has studied their similarities and differences, as well as pros and cons. The Swedish Government agencies SMHI's needs and wishes are exemplified in this study's questions and results. The study is based on a literature study and material has been processed through an analytical induction, using inductive and deductive processes. The established guidelines and framework chosen to be analyzed are Global Reporting Initiative (GRI), ISO 14064 and 2006 IPCC Guidelines. GRI is not only used for environmental issues, it also includes perspectives on social and economic issues. This means that it contains more sustainability perspective than IPCC 2006 and ISO 14064, who only focusing on the environmental perspective. This study identified the pros and cons of all the chosen approaches and if it is appropriate for a governmental agency depends. Is the purpose of working to quantitatively measure the ISO 14064 or IPCC 2006 is applicable. If the purpose is to work with all sustainability perspectives, GRI is applicable. It also depends on what scale government wants to make its calculations, at local, regional, or national level, as the geographic level of scale differs between ISO 14064 and IPCC 2006

    ”Human uses carefully managed”: A critical discourse analysis of the Chagos Marine Protected Area2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The large marine protected area (MPA) declared in 2010 around the Chagos Archipelago, also known as the British Indian Ocean Territory (BIOT), has led to a conflict in the thick of environmental protection, colonialism, sovereignty claims, and the human rights dispute of the Chagossian people that once were exiled from the islands in the 1970s. By applying a Foucauldian inspired critical discourse analysis, this study interprets and examines how the nature/human relationship was portrayed during and after the creation of the Chagos MPA. Applying theories and concepts from political ecology and Foucault’s idea of biopower sheds new light on a conservation effort depicted as a global environmental success by some, and a geopolitical social justice disaster by others. Finally, this thesis applies Tim Ingold’s philosophical concept of the globe and sphere to discuss the implications of inclusion or withdrawal from nature.

    Methane fluxes from tree stems in Amazon floodplains: Evaluating methodological aspect of measuring spatial and seasonal variability in a flooded system2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Tropical wetland-adapted trees are recognized as an important source of regional and global methane (CH4) emissions, by transport of soil gas through wetland trees. However, spatiotemporal variability and controls on the magnitude of tree-mediated CH4 emissions remain unknown as fluxes are poorly constrained. Therefore, we aim to optimize sampling efforts to yield representative emission estimates for distinct types of forest ecosystems and improve knowledge on spatial and temporal variability. We examined the variability in tree stem mediated CH4 fluxes in situ, located in three different floodplains (Solimões, Negro and Tapajós) with various characteristics, during different hydrological seasons. The sampling was conducted by measuring fluxes from 36 trees at each location using closed chambers. All the three study sites, situated in the Amazon region, displayed seasonal variability in CH4 fluxes, with the largest contributions observed during the wet season. A significant difference between Solimões and Negro was detected during the wet season and this may be a result of the different chemical and physical characteristics between the sampling locations. As for within the study sites, zones played a significant role for CH4 flux from trees since the water level influences the fluxes. A strong spatial variability (lower fluxes in the land zone, and the highest flux obtained in the zone with greatest variability between dry and wet conditions) was found. This pattern can be addressed by sampling along flooded and non-flooded zones.

    Språkcafé: "Det är inte så strukturerat, det faller sig naturligt"2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studien undersöker volontärer och deras egna upplevelse av sitt språkcafé som drivs i Röda Korsets regi i en kyrkas lokal i en svensk mellanstor stad, där volontärer och deltagare träffas en kväll i veckan för att träna svenska. Mitt angreppssätt för studien är kvalitativt och mitt empiriska material baseras på mina fältanteckningar från sju deltagande observationer som jag gjort under november och december månad 2018 samt fyra enskilda intervjuer jag utfört med volontärer på språkcafét under samma tid. Studiens resultat visar språkcaféts betydelse för volontärerna och ger en bild av hur miljön inverkar på språkcafét samt hur lärandet sker.

    Cluster Analysis with Meaning: Detecting Texts that Convey the Same Message2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Textual duplicates can be hard to detect as they differ in words but have similar semantic meaning. At Etteplan, a technical documentation company, they have many writers that accidentally re-write existing instructions explaining procedures. These "duplicates" clutter the database.

    This is not desired because it is duplicate work. The condition of the database will only deteriorate as the company expands. This thesis attempts to map where the problem is worst, and also how to calculate how many duplicates there are.

    The corpus is small, but written in a controlled natural language called Simplified Technical English. The method uses document embeddings from doc2vec and clustering by use of HDBSCAN* and validation using Density-Based Clustering Validation index (DBCV), to chart the problems. A survey was sent out to try to determine a threshold value of when documents stop being duplicates, and then using this value, a theoretical duplicate count was calculated.

    Simple cosmological models and their descriptions of the universe2018Independent thesis Basic level (degree of Bachelor), 10,5 credits / 16 HE creditsStudent thesis
    Abstract [en]

    Cosmology is the study of the universe as a whole, and attempts to describe the behaviour of the universe mathematically. The simplest relativistic cosmological models are derived from Einstein's field equations with the assumptions of isotropy and homogeneity. In this thesis, a few simple cosmological models will be derived and evaluated with respect to their description of our universe i.e., how well they match observational data from e.g., the cosmic background radiation and redshift from distant supernovae. The models are derived from Einstein's field equations, which is why a large portion of the thesis will lay the ground work for the field equations by introducing and explaining the language of tensors.

    "Vi är varandras arbetsmiljö": om studiero på högstadiet2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study examines the learning conditions in two seventh grade classes at a high school in Sweden. The classes have been observed during lessons on six occasions and interviews have been done with six students and two educators. The focus is the students' experience of learning conditions in the classroom, what opportunities the students have to shape their work environment and how the students experience their participation. What I have found during my fieldwork is that students and educators agree on what good and calm learning conditions are, but that learning conditions are best understood when it is disrupted. Then other processes also become clear, such as the creation of norms, the students' socialization process and the friendly exercise of power. However, it seems that the students are not fully aware of the opportunities given when they participate in the creation of their work environment.

    Re-negotiating agency: patients using comics to reflect upon acting in situations of abuse in health care2019In: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 19, no 1, article id 58Article in journal (Refereed)
    Abstract [en]

    Background

    There is a growing body of international research that displays the prevalence and character of abuse in health care. Even though most of these studies are conducted from a patient perspective little is known about how patients conceptualize their agency in relation to such situations. This study aimed to explore how patients reason about their potential to act in abusive situations.

    Methods

    Qualitative interviews were conducted with thirteen patients in Sweden. Central in the interviews were three comics, inspired by Boal’s Forum Theatre and part of an earlier online intervention study in which the informants had participated. Each comic showed a situation in which a patient feels abused, and on the opposite side were suggestions for how the patient could act in response. Informants were asked to reflect about situations of abuse and in specific upon the comics. We used the methodology of constructivist grounded theory throughout the study, including the analysis.

    Results

    It appeared that the informants constantly re-negotiated their and other patients’ agency in relation to the specifics of the event, patients’ and staff’s responsibilities, and the patients’ needs and values. This process questions views of agency as fixed and self-evident, and can be understood as part of changing discourses about patients’ social role and possibilities to organize their care. Using a feminist theory of power we expected the informants to elicit instances of resistance to domination, which is central to the comics. While doing that, the informants also hinted at parallel stories of empowerment and less visible forms of agency in spite of domination.

    Conclusion

    The current analysis showed different ways in which the informants constantly re-negotiated their agency in potentially abusive situations. Not only did the informants engage in reflections about immediate responses to these untoward situations, they also engaged in thoughts about strategies that could protect them and counteract abuse in health care over the long-term. This opens up for future research into ways patients organize their care and identify threats and barriers to the care they need, which could be valuable knowledge for care quality improvement.
