    Correlated long-range mixed-harmonic fluctuations measured in pp, p plus Pb and low-multiplicity Pb plus Pb collisions with the ATLAS detector2019Inngår i: Physics Letters B, ISSN 0370-2693, E-ISSN 1873-2445, Vol. 789, s. 444-471Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Correlations of two flow harmonics v(n) and v(m) via three- and four-particle cumulants are measured in 13 TeV pp, 5.02 TeV p+Pb, and 2.76 TeV peripheral Pb+Pb collisions with the ATLAS detector at the LHC. The goal is to understand the multi-particle nature of the long-range collective phenomenon in these collision systems. The large non-flow background from dijet production present in the standard cumulant method is suppressed using a method of subevent cumulants involving two, three and four subevents separated in pseudorapidity. The results show a negative correlation between v(2) and v(3) and a positive correlation between v(2) and v(4) for all collision systems and over the full multiplicity range. However, the magnitudes of the correlations are found to depend on the event multiplicity, the choice of transverse momentum range and collision system. The relative correlation strength, obtained by normalisation of the cumulants with the < v(n)(2)> from a two-particle correlation analysis, is similar in the three collision systems and depends weakly on the event multiplicity and transverse momentum. These results based on the subevent methods provide strong evidence of a similar long-range multi-particle collectivity in pp, p+Pb and peripheral Pb+Pb collisions. (C) 2019 The Author.

    International comparison of treatment strategy and survival in metastatic gastric cancer2019Inngår i: BJS OPEN, ISSN 2474-9842, Vol. 3, nr 1, s. 56-61Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BackgroundIn the randomized Asian REGATTA trial, no survival benefit was shown for additional gastrectomy over chemotherapy alone in patients with advanced gastric cancer with a single incurable factor, thereby discouraging surgery for these patients. The purpose of this study was to evaluate treatment strategies for patients with metastatic gastric cancer in daily practice in five European countries, along with relative survival in each country. MethodsNationwide population-based data from Belgium, Denmark, the Netherlands, Norway and Sweden were combined. Patients with primary metastatic gastric cancer diagnosed between 2006 and 2014 were included. The proportion of gastric resections performed and the administration of chemotherapy (irrespective of surgery) within each country were determined. Relative survival according to country was calculated. ResultsOverall, 15 057 patients with gastric cancer were included. The proportion of gastric resections varied from 81 per cent in the Netherlands and Denmark to 183 per cent in Belgium. Administration of chemotherapy was 392 per cent in the Netherlands, compared with 632 per cent in Belgium. The 6-month relative survival rate was between 390 (95 per cent c.i. 378 to 402) per cent in the Netherlands and 541 (521 to 569) per cent in Belgium. ConclusionThere is variation in the use of gastrectomy and chemotherapy in patients with metastatic gastric cancer, and subsequent differences in survival.

    Tidal changes in PaO2 and their relationship to cyclical lung recruitment/derecruitment in a porcine lung injury model2019Inngår i: British Journal of Anaesthesia, ISSN 0007-0912, E-ISSN 1471-6771, Vol. 122, nr 2, s. 277-285Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Tidal recruitment/derecruitment (R/D) of collapsed regions in lung injury has been presumed to cause respiratory oscillations in the partial pressure of arterial oxygen (PaO2). These phenomena have not yet been studied simultaneously. We examined the relationship between R/D and PaO2 oscillations by contemporaneous measurement of lung-density changes and PaO2. Methods: Five anaesthetised pigs were studied after surfactant depletion via a saline-lavage model of R/D. The animals were ventilated with a mean fraction of inspired O-2 (FiO(2)) of 0.7 and a tidal volume of 10 ml kg(-1) Protocolised changes in pressure-and volume-controlled modes, inspiratory: expiratory ratio (I:E), and three types of breath-hold manoeuvres were undertaken. Lung collapse and PaO2 were recorded using dynamic computed tomography (dCT) and a rapid PaO2 sensor. Results: During tidal ventilation, the expiratory lung collapse increased when I: E <1 [mean (standard deviation) lung collapse = .7 (8.7)%; P<0.05], but the amplitude of respiratory PaO2 oscillations [ 2.2 (0.8) kPa] did not change during the respiratory cycle. The expected relationship between respiratory PaO2 oscillation amplitude and R/D was therefore not clear. Lung collapse increased during breath-hold manoeuvres at end-expiration and end-inspiration (14% vs 0.9-2.1%; P<0.0001). The mean change in PaO2 from beginning to end of breath-hold manoeuvres was significantly different with each type of breath-hold manoeuvre (P<0.0001). Conclusions: This study in a porcine model of collapse-prone lungs did not demonstrate the expected association between PaO2 oscillation amplitude and the degree of recruitment/derecruitment. The results suggest that changes in pulmonary ventilation are not the sole determinant of changes in PaO2 during mechanical ventilation in lung injury.

    Sex-specific effects of parasites on telomere dynamics in a short-lived passerinethe blue tit2019Inngår i: The Science of Nature: Naturwissenschaften, ISSN 0028-1042, E-ISSN 1432-1904, Vol. 106, nr 1-2, artikkel-id 6Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Parasitic infections potentially drive host's life-histories since they can have detrimental effects on host's fitness. Telomere dynamics is a candidate mechanism to underlie life-history trade-offs and as such may correlate with observed fitness reduction in infected animals. We examined the relationship of chronic infection with two genera of haemosporidians causing avian malaria and malaria-like disease with host's telomere length (TL) in a longitudinal study of free-ranging blue tits. The observed overall infection prevalence was 80% and increased with age, constituting a potentially serious selective pressure in our population. We found longer telomeres in individuals infected with a parasite causing lesser blood pathologies i.e. Haemoproteus compared to Plasmodium genus, but this only held true among males. Female TL was independent of the infection type. Our results indicate that parasitic infections could bring about other types of costs to females than to males with respect to TL. Additionally, we detected linear telomere loss with age, however a random regression analysis did not confirm significant heterogeneity in TL of first breeders and telomere shortening rates in further life.

    Vad blir det för bok?: En undersökning om valen av litteratur i Svenska 12019Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Syftet med undersökningen har varit att se hur användningen av skönlitteratur ser ut i Svenska 1. Genom att fokusera på lärarnas val och tankar har jag undersökt vilka titlar som arbetas med i klassrummet inom Svenska 1, samt vilka pedagogiska aspekter som ligger till grund för de litterära val lärarna gör. Mina frågeställningar har varit Vilka skönlitterära författare och verk används i Svenska 1? Går det att tala om en kanon? samt Vad är det som ligger till grund för valet av skönlitteratur i Svenska 1? Vilka är de didaktiska utgångspunkterna?

    Undersökningen bygger på två typer av metoder. En kvantitativ enkätundersökning med 34 svarande som genomförts via en Facebookgrupp för svensklärare. Samt en kvalitativ intervjuundersökning då jag intervjuat två lärare. Dessa två metoder kompletterar varandra i och med att enkätundersökningen bidrar med underlag och intervjuerna kan fylla i eventuella frågor. Det finns ett antal begrepp som använts vid flera tillfällen i uppsatsen som jag anser behövs förtydligas. Jag har bland annat valt att diskutera begreppet kanon eftersom att jag upplever kanon som ett viktigt begrepp för att kunna undersöka och diskutera skönlitteratur i skolan. I undersökningen presenterar jag Lars Brinks diskussion kring kanon och refererar även till Harold Bloom. Jag har definierat begreppet ungdomslitteratur och har då använt mig av nationalencyklopedins definition.

    För att relatera min undersökning till tidigare forskning har jag har utgått ifrån Lars Brinks undersökning från 2006 där han undersökt hur lärare värderat olika aspekter när de valt sin litteratur. Han beskriver hur en av de aspekter som lärare upplever som viktigast är om boken tillhör en kanon. Han kommer även fram till att aspekter som eleverna enkelt kan relatera till hamnar längre ner på listan, som exempelvis ungdoms- och populärlitteratur. Jag har också använt mig av Ingrid Mossberg Shüllerqvists forskning som också bygger på lärares syn på litterära val i klassrummet. Hennes resultat skiljer sig från Brinks och hon kommer fram till att de lärare hon intervjuat menar att de blir mer och mer elevorienterade när de väljer bokval och att de upplever att populär- och ungdomslitteraturen får en allt större plats i skolan.  Två ytterligare forskare som jag valt att förhålla mig till är Birgitta Bommarco och Gunilla Molloy, de har båda ett fokus på varför man ska läsa och hur elever ska läsa för att kunna ta till sig av litteraturen på ett så bra sätt som möjligt. De båda lyfter att lärare gärna läser med elever för att uppmuntra till mer läsning, samt att eleverna lär sig bäst om de har möjlighet att relatera till litteraturen, Bommarco menar därför att det är viktigt att läraren väljer litteratur tillsammans med eleverna.

    När jag relaterar mitt resultat till den tidigare forskningen går det att hitta både likheter och skillnaden. Min första frågeställning löd: Vilka skönlitterära författare och verk används i Svenska 1? Går det att tala om en kanon? Resultatet visar att det är en stor variation på vilka böcker som används. Bland de 34 lärarna som besvarade enkäten nämndes det att de sammanlagt arbetat med 43 böcker det senaste året. Det framgick även att det vanligaste alternativet för Svenska 1 var att eleverna själva fick välja böcker. Detta beskrev även en av de två lärare jag intervjuat. Hon motiverade detta genom att förklara att hon vill att läsningen i Svenska 1 ska vara inbjudande och uppmuntra till mer fortsatt läsning. Resultatet liknar därför Mossberg Shüllerqvists som menar att lärare tenderar till att ha en mer elevorienterad litteraturlista. Mitt resultat visade också att de 29 av de 43 nämnda titlarna var böcker som jag anser kunde klassas som populärlitteratur. Även många av de titlar som blev nämnda vid fler än ett tillfälle kunde klassas som populärlitteratur vilket visar på att populärlitteratur var vanligt förekommande i klassrummet. Mitt resultat visade även på att en del klassiker användes, men inte i samma höga utsträckning och av lika många lärare. Många lärare berättade också att de arbetade mer med klassikerna i senare Svenska 2. Även om det framgick att lärare hade ett klassikertänk i bakhuvudet när de valde litteratur är det tydligt att en varierad litteraturlista som anpassats till klassen är mer viktig än att läsa tunga klassiker tillsammans med eleverna i Svenska 1.

    Min andra frågeställning undersöker vad det är som ligger till grund för valet av skönlitteratur i Svenska 1? Där stämmer mitt resultat inte helt överens med Lars Brinks. Jag lyckades skapa följande nio kategorier utifrån mitt resultat: Elevernas intresse, elevernas förkunskaper, koppling till kursplan, tillgänglighet,

    tankeväckande, lärarens intresse, klassikertänk, litterär kvalité och tillgång till material. Jag kunde även dela in dessa i tre överkategorier: praktiska, elevorienterade och kanonorienterade. Det framgick att det var de mer elevorienterade, som elevernas intressen eller elevernas färdigheter som upplevdes som mest viktiga bland lärarna. Sedan kom de mer praktiska som huruvida texterna gick att arbeta med i klassrummet i relation till kursplan eller om de fanns i klassuppsättning. Den överkategorin som var minst viktig är den jag valt att kalla kanonorienterad, alltså huruvida boken klassas som en klassiker eller om det är en bok av ”god kvalité”. Mitt resultat är emellertid inte helt enhetligt. Det är nämligen en av de intervjuade lärarna som menar att den viktigaste aspekten när hon väljer litteratur är om den finns i klassuppsättning. Samma lärare värderar också om det finns färdigt arbetsmaterial till boken väldigt högt. Detta skulle kunna bero på att hon är relativt nyexaminerad då den andra intervjuade läraren menar att det blir enklare att använda sig av olika böcker med tiden och att erfarenheten gör att hon vågar testa olika typer av böcker. Jag upplever ändå att det går att se ett resultat som visar att det fokus på kanon som Brink visar i sin undersökning från 2006 inte längre förekommer på samma sätt år 2018 utan att det idag finns ett större fokus på att anpassa läsningen efter eleverna.

    Space-time disaggregation of precipitation and temperature across different climates and spatial scales2019Inngår i: JOURNAL OF HYDROLOGY-REGIONAL STUDIES, ISSN 2214-5818, Vol. 21, s. 126-146Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Study region: This study focuses on two study areas: the Province of Trento (Italy; 6200 km(2)), and entire Sweden (447000km(2)). The Province of Trento is a complex mountainous area including subarctic, humid continental and Tundra climates. Sweden, instead, is mainly dominated by a subarctic climate in the North and an oceanic climate in the South. Study focus: Hydrological predictions often require long weather time series of high temporal resolution. Daily observations typically exceed the length of sub-daily observations, and daily gauges are more widely available than sub-daily gauges. The issue can be overcome by disaggregating daily into sub-daily values. We present an open-source tool for the non-parametric space-time disaggregation of daily precipitation and temperature into hourly values called spatial method of fragments (S-MOF). A large number of comparative experiments was conducted for both S-MOF and MOF in the two study regions. New hydrological insights for the region: Our experiments demonstrate the applicability of the univariate and spatial method of fragments in the two temperate/subarctic study regions where snow processes are important. S-MOF is able to produce consistent precipitation and temperature fields at sub-daily resolution with acceptable method related bias. For precipitation, although climatologically more complex, S-MOF generally leads to better results in the Province of Trento than in Sweden, mainly due to the smaller spatial extent of the former region.

    ”Tänk att allt är mitt på riktigt nu”: En kvalitativ textanalys av barnböcker med tema flykt2018Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna studie syftar till att undersöka hur karaktärer på flykt framställs i ett urval samtida barnböcker samt undersöka platsen och hemmets funktion för att se vilka värderingar som förmedlas. Detta sker genom en kvalitativ textanalys av fem barnböcker utgivna mellan år 2008–2017. De böcker som analyseras är Mina två filtar, Milos flykt, Pudlar och pommes, Fyra fötter, två sandaler och Om jag får stanna. Studien utgår från två forskningsfrågor: Hur framställs litterära karaktärer på flykt utifrån kategorierna genus, etnicitet och klass? Hur skildras samt relaterar karaktärer till platsen och hemmet? Studien utgår från de teoretiska utgångspunkterna intersektionalitet, teorier om hem, hemlöshet och identitet och teorier om skönlitteraturens roll. Den förstnämnda utgångspunkten är i studien begränsad till kategorierna genus, etnicitet och klass.

    Resultatet visar på en relativt varierad skildring av både karaktärer och flyktupplevelsen. I samtliga verk är det ovanligt att kommentera karaktärers utseende och etniska bakgrund, både vad gäller karaktärer på flykt och karaktärer i mottagarlandet. Personbeskrivningar av huvudkaraktärer sker endast i bild eller inte alls. Karaktärer i de analyserade böckerna både utmanar och upprätthåller genusnormer. I majoriteten av böckerna tillskrivs karaktärerna både stereotypiskt kvinnliga och manliga egenskaper och verkar således inom de båda fälten. Klassperspektivet skildras främst genom att samtliga karaktärer lever i utsatta situationer utan egen bostad och arbete. Hemmet och framförallt platsen är av stor betydelse i samtliga verk. I fyra av fem böcker fokuseras mottagarlandet och integrationsproblematiken medan hemlandet i regel anonymiseras och får stå tillbaka.

    Constructing the Suburb: Swedish Discourses of Spatial Stigmatisation2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    By exploring representations of place, this thesis treats practices of spatial stigmatisation in the context of segregated Swedish cities. In three papers, different aspects of stigmatisation and place-making are discussed and analysed, where the overarching ambition is to identify and critically deconstruct the ideology behind stigma as well as suggest ways of making representation positive. In other words, this thesis takes issue with the negative labels attached to certain urban areas by exploring dominant discursive trends and mechanisms, or techniques, of creating spatial stigma.

    Theoretically, the analysis is informed by postcolonial critical research on segregation and representations of people and place, where place-making is of particular importance. The case study consists of printed news media and political discourse concerning stigmatised urban areas in Sweden, and the method is inspired by critical discourse analysis.

    The empirical material covers a period of twenty years, and the analysis is particularly focused on constructions of ‘race’ and poverty and how these two dimensions intertwine. The main findings point to a dominant trend of representing stigmatised neighbourhoods as failed and miserable places that are not considered part of Sweden. They become racialised both through representations of the neighbourhoods as foreign and unintegrated places and through representations of the residents, usually categorised as the ‘immigrants’, as culturally different from ‘Swedes’.  There are signs of a more critical discourse which challenges the negative representations, but it remains weak compared to the predominance of the negative reporting.

    Abstract [en]

    Using Sweden and Swedish newspapers as our case, we analyse 16 years of news reports on stigmatised areas. Particular attention is paid to what we refer to as mechanisms of stigma, in other words; news media techniques of representing place and residents in a stigmatising manner. These consist of firstly grouping neighbourhoods together based on common traits; second, comparing and contrasting places with each other; and thirdly, racialised blame, which constructs ethnic minorities as problems. Mechanisms of stigma are placed in the context of dominant themes of news media reporting on stigmatised neighbourhoods, where we identified categories of hopelessness, violence and colonial representations as the most common framings of the news stories. In addition, the thematic analysis has allowed us to observe the increase of stories of violence and terrorism in news reports on stigmatised neighbourhoods, in turn connected to the overall inflation of islamophobia and nationalism, with focus on Muslims and Islam as threats to integration, safety and national unity.

    Abstract [en]

    Critical research on residential segregation has long emphasised issues of inequality and discrimination as crucial factors for its production and reproduction. Equally, research on spatial stigmatisation is recognised in scholarly debate as a highly problematic practice which not only shapes policy interventions but also affects the residents of targeted areas. With the ambition of problematising the relationship between residential segregation and stigmatisation, this article analyses printed newspaper editorial discourse in order to critically examine constructions of place. News media has been argued to be a key agent in the practice of stigmatisation, which makes editorial statements highly significant when it comes to how the newspaper perceives the importance of stigmatisation. In addition, the theoretical framework of residential segregation as a process based in structural inequalities provides the basis for identifying stigmatisation of poor and racialised neighbourhoods as an often neglected but indispensable piece of the puzzle. It is argued here that editorials’ neglect of practices of stigmatisation reproduce and simultaneously hide power relations inherent to processes of inequality.

    Abstract [en]

    In the context of Swedish anti-segregation strategies and area-based policies, this article critically examines how parliamentary motions create and reproduce a racialised understanding of housing segregation. A close examination of political language reveals a predominantly negative framing of both people and place, where already stigmatised areas are demonised as segregated places where the ‘immigrants’ live. In particular, the disadvantaged position of many of the residents in stigmatised areas is expressed through a consistent construction of non-‘Swedishness’; of not being considered part of Sweden based on perceived cultural difference framed as an individual or spatial attribute. In addition, the condition of not belonging is believed to merge with a condition of ‘utanförskap’, (‘outsiderness’). Despite the ideological differences between the various political parties, de-colonisation is still lacking in the Swedish political discourse on ethnic residential segregation.

    Utdelningspolitik då och nu: En jämförande studie av företags utdelningspolitik 1987 och 20172019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Idag ställer aktieägare höga avkastningskrav på företag vilket resulterar i att de delar ut allt högre utdelningar. Beteendet har växt fram ur kvartalsekonomin och leder till att aktieägare och företags beteende blir allt mer kortsiktigt. Syftet med denna studie är att undersöka om det skett en förändring av företagens utdelningsandel och dess utdelningspolicy genom att kvantitativt och kvalitativt jämföra åren 1987 och 2017. Studien finner att det mellan åren har skett en ökning i den faktiska utdelningsandelen. Det framkommer även att det finns skillnad i företagens utdelningspolicy där den 2017 är mer omfattande med bland annat fler mål och motiveringar för utdelningarna. Det är svårt att avgöra vad dessa förändringar kan bero på men resultatet från studien kan antyda på att företagen vill förmedla att de bedriver både en kortsiktig och långsiktig utdelningspolitik.

    Software Engineering using DevOps- a Silver Bullet?2019Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Today we have technology that help us scan millions of medical databases in a glimpse of an eye and self-driving cars that are outperforming humans at driving. Technology is developing so fast that new updates in the technology world are commonplace to us and we are more often frustrated in case something is not up to speed. Technology is moving so quickly and in order for humans to keep up with the development needed in the tech business, different methodologies for how to optimise the development process have been applied, some that work better than others. But just as fast as the technology changes, the methodologies used change with them. Recently a new term has entered the methodologies field. This term is said to bring faster deployment, decreased failures and improved the loyalties within the teams. The term in question, is called DevOps.

    This study is about uncovering the world of DevOps. This thesis is exploring the term in real teams in order to find out whether or not DevOps is the silver bullet it makes out to be. The study is based on ten interviews with people at different organisations, using DevOps, and will find out how these interviewees use and feel about DevOps. Found in these interviews is that both the involvement in, interpretation and implementation of the term varies between the interviewees. Nothing was all the same between them. All interviewees were very positive about the term and its contributions to the process and would definitely implement it in any new team. However, also found is that development in organisations is leaning towards becoming more single minded. When creating and reforming teams, organisations rather exclude constellations of different human thoughts and departments in order to rely on different development platforms instead. To conclude from this is that DevOps might take away work from collaborating humans in favour of the speed we achieve in the assisting technologies. This in a possible alarming way since single minded teams can miss important aspects in development which can have a dangerous outcome. Even though this might be a truth, DevOps is seen as something very positive and could just be the silver bullet it is talked about it to be, but this only if each team can interpret it, implement it and use it in their own way.

    THE EFFECT OF BOARD SIZE ON FIRM PERFORMANCE AND HOW THIS RELATIONSHIP IS INFLUENCED BY UNCERTAINTY AVOIDANCE2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This study investigates the effect of board size on firm performance measured through return on assets. Furthermore, this study investigates how this relationship is influenced by uncertainty avoidance. An unbalanced global sample of more than 9,000 observations divided over 23 countries for the time period 2006 – 2016 is used to examine this. In contrast with other studies a global sample is used and a new variable, uncertainty avoidance is added. In the study, I find that board size positively affects firm performance. Furthermore, I find that uncertainty avoidance affects the relationship between board size and firm performance. Although in contrast with other studies, my evidence supports the argument that firms should increase their board size to reduce agency costs and increase board capital.

    The Influence of Corporate Governance Quality and Growth Opportunities on Firms’ Payout Policy2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This paper examines the effect of corporate governance quality on firms’ payout policy. We analyze a global sample of 3,904 firms (25,773 firm-year observations) over the period 2002-2016. I find that corporate governance quality is positively related to payout ratios, consistent with the perspective of the free cash flow hypothesis (Jensen, 1986) and the outcome dividend model (LLSV, 2000). Moreover, consistent with findings of Mitton (2004) the positive relationship between firm’s corporate governance and dividend payout mainly holds for countries with strong shareholder or creditor protection, suggesting that firm-level corporate governance and country-level protection rights are complements rather than substitutes. This study also shows that firms with high corporate governance quality are less likely to disburse cash to their shareholders when controlling for country-level shareholder rights. Furthermore, this study contributes to the existing literature by investigating share repurchases and finds that well governed firms distribute less cash through share repurchases and total payout when they experience high growth opportunities. Moreover, the results suggest that countries that experience stronger shareholder and creditor rights reduce the positive impact that corporate governance quality has on share repurchases and total payout.

    The Moderating Role of Institutional Quality, Leverage and Size in the Relationship between R&D Investments and Firm Value2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This study examines the relationship between R&D intensity (R&D/sales) and firm value. Additionally, both the moderating effect of endogenous firm characteristics (i.e. firm size, leverage and the interaction between size and leverage) and institutional quality are considered. By employing a sample of 1,833 firms throughout 49 countries, this study finds evidence supporting a positive association between R&D and firm value in its cross-national sample. Moreover, the results support the positive moderating effect of leverage on the relationship between R&D and firm value, in favour of the disciplining role of debt. Furthermore, a negative moderating effect of firm size is found, suggesting that smaller firms possess a superior ability to appropriate value from their R&D investments. Lastly, the size-leverage interaction reveals that small firms with high leverage reap the greatest firm value from their R&D investments.

    Board independence and firm performance: The moderating effect of ownership concentration and shareholder protection2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This research studies the moderating effect of ownership concentration and the strength of investor protection on the relationship between the level of board independence, as measured by the number of non-executive directors in relation to total number of directors and the firm performance. Using a sample of 9018 observations on all non-financial publicly listed firmsin 27 OECD countries between the year 2012 and 2015. The findings show a positive correlation between board independence and firm performancein all regression models. Furthermore, I find the negative moderating effect on both shareholder concentration and investor protection on the main relationship.

    Board Gender Diversity and Firm performance: How do Educational Levels and Board Gender Quotas affect this Relationship? Evidence from Europe2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    The majority of previous research in the field of board diversity was dedicated to the direct link between board gender diversity and firm performance. Grounded in Agency- and Resource dependence theory, this thesis expands on this research and examines the main relationship including the influence of two additional factors: educational level of female directors and mandatory board gender quotas. Analyzing a sample of 454 European firms (3,871 firm-year observations) over the period 2007-2017, a positive relationship between board gender diversity and firm performance is found. Furthermore, the results suggest that educational levels or board gender quotas do not affect this relationship. The effects on firm performance differ depending on whether legislative measures or voluntary initiatives are in place, i.e. in contrast to legislative quotas, voluntary initiatives enhance firm performance.

    Corporate payout policy: a study on multinationality and legal origin2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This paper investigates determinants of payout levels and payout composition in multinational corporations and domestic corporations and how payout differs between the two, as well as the effect of a country’s legal tradition on payout, on a worldwide sample. My main findings are that multinational corporations’ total payout is slightly lower than domestic corporations’ payout when taking into account a country’s legal tradition affects. No support is found that multinationals and domestic corporations differ in payout composition and payout composition is not changing over time, according to my results. My findings are partly consistent with theories on how ownership structures and agency problems affect payout policy. Still, the puzzle in unsolved.

    Analysts forecast error and tenure: The moderating effect of country-culture dimensions2019Independent thesis Advanced level (degree of Master (Two Years)), 20hpOppgave
    Abstract [en]

    This research investigates the moderating effect of cultural differences between countries on the relationship between tenure and analyst accuracy. To investigate this research looks at the expected earnings per shares and the realised earnings per share from the shares included into the AEX, CAC, DAX and FTSE. The dataset consists of 466 analysts and 3.040 observations. The time period observed is 2015, 2016 and 2017. This research shows that there is no significant relationship between tenure and analyst accuracy. The results show that masculinity, individualism and long term orientation have a moderating effect on analyst accuracy. A practical implication is that managers could employ methods to change the work culture to increase analyst accuracy. An academic implication of this research is that culture should be included as a moderating factor in future analyst accuracy research.

    Stöd eller styrning?: En studie av Skolverkets stödmaterial2018Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I den här studien undersöktes hur Skolverkets stödmaterial kan påverka lärares autonomi. I studiens teoretiavsnitt presenteras begreppet continuing professional development  (CPD) som handlar om den fortbildning lärare förväntas genomgå under sitt yrkesliv och hur CPD kan ses som ett sätt att styra lärares arbete. Skolverket anses vara en betrodd källa vid val av fortbildning. I avsnittet behandlas även vad autonomi innebär för lärare. Studiens empiriska material bestod av fyra av Skolverkets stödmaterial i undervisningen. Det analytiska verktyg som användes för att kunna undersöka stödmaterialens påverkan på autonomin baserades på LaCoes (2008, s. 39) sex dimensioner av den individuella autonomin. I studiens forskningsöversikt presenteras ett urval av den forskning som genomförts rörande styrningen och olika faktorer som kan påverka styrningen av den svenska skolan. I bakgrunden presenteras den Tillitsdelegation som Regeringen tillsatte år 2016 för att undersöka hur styrningen av bland annat skolan kan förbättras och hur reformerna påverkat hur styrningen av skolan sett ut.

    Studiens resultat visade att lärares autonomi kan påverkas av innehållet i stödmaterialen och att stödmaterialen kan anses styrande. Analysen av empirin visar även att det finns detaljstyrning i materialens innehåll som liknar en regelstyrning.

    Vem bryr sig om grupprum och lokaler?: Alternativa arbetsplatser i förhållande till ramfaktorer2018Independent thesis Basic level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna studie har genomförts för att bidra med kunskap om hur lärare arbetar med alternativa arbetsplatser så som grupprum och övriga lokaler i sin undervisning med utgångspunkt ur ett ramfaktorteoretiskt perspektiv. Studien visar att lärare nyttjar alternativa arbetsplatser under grupparbeten och enskilt arbete, för att skapa arbetsro och för att elever ska kunna växa och utvecklas i sitt lärande.

     

    Den kvalitativa studien genomfördes genom intervjuer med lärare som verkar inom grundskolan. Intervjuerna analyserades och diskuterades sedan vidare i diskussionsavsnittet där även kopplingar till den tidigare forskningen. Studiens resultat visar att lärare använder alternativa arbetsplatser i förhållandevis låg utsträckning, i den mån de anser sig kunna, men gärna gjort det i högre grad.

    Coercion and its Effects: Evidence from the Israel-Palestine Conflict2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Counterinsurgency, state repression and other forms of coercion have multiple adverse effects. Although a state’s use of threats and force should deter an opposition group, these measures often stimulate resistance. And although state-led coercion aims to influence an opposition group, coercive practices have social, economic and political consequences for civilians. This dissertation studies the efficacy and effects of coercive policies in the context of the Israel-Palestine conflict. The four composite essays investigate the impact of Israel’s practice of house demolition and construction of a separation barrier on Palestinians’ conflict preferences and use of violence, as well as the broader consequences of these policies for Palestinian communities. Essay I questions the conventional wisdom that the selective targeting of militants can be an effective counterinsurgency strategy. Through a survey of Palestinians, it demonstrates that house demolition can generate opposition to peace when it is perceived as indiscriminate in its targeting, even if it is selective by design. Essay II distinguishes between the mechanisms of collective threat and personal fear in state repression. In a longitudinal study of administrative demolition orders, it finds that orders issued against communal structures increase preferences for violence and militant political parties, suggesting that collective threats backfire. Essay III quantifies the economic consequences of counterinsurgency by measuring the separation barrier’s impact on Palestinian employment and wages. It further shows that this economic impact increases the rate of Israeli conflict fatalities, demonstrating that economic consequences of coercion can stimulate violent resistance. Essay IV conceptualises a state’s separation and exclusion of particular population groups as a general phenomenon and form of state repression. It draws on historical cases worldwide and presents the enclosure of Palestinian communities in special zones of the separation barrier as a contemporary example. The essays are empirical studies which use survey methods, quantitative analysis, principles of experimental design, qualitative sources and field work as a basis for description and explanation. As a whole, the dissertation contributes to the study of coercion by calling attention to understudied forms of coercion and identifying particular mechanisms by which threats and force can result in adverse effects.

    Två i ett, nu är ledarskapet komplett: En kvalitativ studie av ledarskapskompetenser i kris och normala förhållanden.2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna studie ämnar undersöka en organisations upplevda behov av kompetenser som en ledare, vilken ska hantera både kris och normala förhållanden, bör besitta. Tidigare teorier som behandlar ledarskapskompetenser tenderar att begränsa sig till en av situationerna, medan denna studie istället menar att en integrerad modell bör utvecklas då en ledare troligtvis kommer att agera i båda situationer. En kvalitativ undersökning genomförs därför med hjälp av nominalgruppteknik i en ledningsgrupp på Livsmedelsverket för att identifiera och rangordna de kompetenser som respondenterna anser viktigast. En tabell som tar hänsyn till båda situationerna sammanställs utefter resultatet och jämförs sedan med befintlig teori. Studien sammanfattas med att teorierna endast delvis uppfyller Livsmedelsverkets eftersträvade ledarskapskompetenser, varför ett behov av en sådan modell finns.

    The Creative Networker: Predicted Relations between Network Behavior and Creativity2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The purpose of the present study was to analyze the significance ofcreativity for network behavior. Similar to other network behavioral studiesthe multidimensional approach was utilized where networking was dividedinto sub dimensions with external and internal counterparts. The domainspecific approach to creativity was used in order to attempt to determinewhich creative domain is significant for different networking behaviors.106 individuals participated in the study and the sample is considered anon-random convenience sample. The results showed that certain networkbehaviors interacted with different creative domains. The creative domainof everyday and verbal creativity were both unique predictors of networkbehavior and were the creative domains who were the most relevant.Structural facets in the form of work experience, organizational size andbiological gender were also explored. Work experience was shown to be aweak moderating variable to the relationship of network behavior andcreativity. Organizational size had no significant results and biologicalgender was significant for two of the creative domains: Math / scientificand artistic creativity. Results from the present study provide furtherevidence towards an area which is relatively new. The findings can be usedto create an empirical foundation in recruitment scenarios which mayrequire individuals with particular set of psychological traits.

    Aktieåterköp på den svenska marknaden: Bakomliggande motiv till återköp under tidsperioden 2010-20172018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna studie undersöker bakomliggande motiv till aktieåterköp på den svenska marknaden och hur marknaden reagerar vid annonseringen av utnyttjande av aktieåterköp. Utifrån 154 annonseringar mellan åren 2010-2017 identifieras tre bakomliggande motiv till aktieåterköp: Förse incitamentsprogram, förändring av kapitalstruktur/distribution av överskottslikviditet och tillhandahålla aktier för förvärv av företag eller annan egendom. Studien finner att 45% av annonseringarna hade incitamentsprogram som minst ett motiv, en ökning jämfört med perioden 2000- 2009 där siffran var 33%. Även den abnorma avkastningen vid annonseringen av utnyttjande av aktieåterköp undersöks genom en eventstudie. Resultaten visar en abnorm avkastning vid annonseringstillfället på 1,341%, utan hänsyn till bakomliggande motiv. Med hänsyn till bakomliggande motiv vid annonseringen uppmätts en abnorm avkastning på 1,5% för kapitalstruktur/distribution av överskottslikviditet, 1,332% för förvärv av företag eller annan egendom och 0,915% för incitamentsprogram.

    Knowledge elicitation as abstraction of purposive behaviour2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Researchers use knowledge elicitation methods to document expert knowledge for the primary purpose of understanding cognitive processes and with this understanding, technical solutions to resolve human factors issues can be produced. This dissertation offers a novel perspective on knowledge elicitation as an abstraction process. Such a theoretical framework has emerged by consolidating the ecological approach of Brunswikian psychology with the ideas of tacit and personal knowledge of Polanyian epistemology. Traditionally, knowledge elicitation has been considered an extraction process in which knowledge can be readily transferred from one individual to another. Here, this traditional position is rejected in favour of Polanyi’s premise that much of the knowledge individuals possess is tacit in nature, which implies that it cannot be documented easily, expressed in explicit form or explained. In this dissertation, knowledge is characterised as a personal process of knowing, highlighting context as a subjective knowledge structure of personal experiences that is formulated implicitly and indirectly over time through a dynamic interaction with the environment. Therefore, tacit knowledge cannot be articulated or shared; however, learners can be inspired by observing other individuals' purposive (i.e., goal-directed) behaviours and thus shape their own tacit knowledge once they practise the observed skills and develop conceptual understanding through reasoning about the learning process. Knowledge elicitation thereby makes use of observations, questions, or more structured process tracing methods in environments familiar to the observed individuals to elicit purposive behaviour from them. Accordingly, functional descriptions can be produced in this process that further conceptual understanding of a particular domain. Knowledge elicitation procedures are a powerful set of methods for reaching such functional descriptions. Moreover, by understanding the resulting knowledge elicitation data as an abstraction derived from multiple collection points in the same environment, the focus shifts from purely subjective mental constructs to the impact of environmental constraints.

This issue emerged within a project with the aim to develop a human–machine interface for a highly automated long-haul vehicle. To handle the problem, a formative strategies analysis method with promises to enable desktop analyses through predefined strategy categories was adopted. The method was used to investigate strategies for controlling the future long haul vehicle by conducting workshops with today's drivers. The method was shown to be a valuable asset in eliciting strategies for revolutionary design.

    Abstract [en]

    The present study investigated differences in visual expertise across levels of proficiency in train traffic control during a simulated scenario. Eye tracking metrics found to correlate with expertise reported in a meta-analysis on visual expertise were used. The aim of the study was to investigate whether the same results found in the meta-study could be obtained in the less controlled and dynamic work environment of train traffic control. Studies of this character are rare and also notoriously difficult to conduct due to a high level of potential noise. Results of the study indicates that eye behaviour seemed to correlate with years of experience also in a more naturalistic setting, but it did not correlate with expert ranking by instructors or a post-hoc measure of proactivity in task performance. A discussion is provided where a delineation of experience and expertise is made in light of differences between eye movement behaviour and cognitive aspects of problem-solving.

    Exotic Ribosomal Enzymology2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This thesis clarifies intriguing enzymology of the ribosome, the multiRNA/multiprotein complex that catalyzes protein synthesis (translation). The large ribosomal RNAs (23S and 16S rRNAs in E. coli) are post-transcriptionally modified by many specific modification enzymes, yet the functions of the modifications remain enigmatic. A deeper insight into two of the 23S rRNA S-adenosyl-methionine-requiring methyltransferase enzymes, RlmM and RlmJ, was given by investigating substrate specificity in vitro. Both enzymes were able to methylate in vitro-transcribed, modification-free, protein-free, 2659-nucleotide-long 23S rRNA. Furthermore, RlmM was able to methylate the 611-nucleotide-long Domain V of the 23S rRNA alone and RlmJ could modify the A2030 with only 25 surrounding nucleotides.

    Translation is evolutionary optimized to incorporate L-amino acids to the exclusion of D-amino acids in the cell. To understand how, and how to engineer around this restriction for pharmacological applications, detailed kinetics of ribosomal dipeptide formation with D- versus L-phenylalanine-tRNA were determined. This was done by varying the concentrations of EF-Tu (which delivers aminoacyl-tRNAs to the ribosome) and the ribosome, as well as changing the tRNA adaptor. Binding to EF-Tu was shown to be rate limiting for D-Phe-tRNA at a low concentration of EF-Tu. Surprisingly, at a higher (physiological) concentration of EF-Tu, binding and subsequent dipeptide synthesis became so efficient that D-Phe incorporation became competitive with L-Phe, and accommodation/peptide bond formation was unmasked as a new rate-limiting step. This highlighted the importance of D-aminoacyl-tRNA deacylase in restricting translation with D-amino acids in vivo.

    Although polypeptides are intrinsically colorless, it is remarkable that evolution has nevertheless enabled ribosomes to synthesize highly colored proteins (chromoproteins). Such eukaryotic proteins reside in coral reefs and undergo self-catalyzed, intramolecular, chromophore formation by reacting with oxygen in a manner highly similar to that of green fluorescent protein. The potential utility of different colored chromoproteins in E. coli was analyzed via codon-optimized over-expression and quantification of maturation times, color intensities and cellular fitness costs. No chromoprotein was found to have the combined characteristics of fast maturation, intense color and low fitness cost. However, semi-rational mutagenesis created different colored variants with identical fitness costs suitable for competition assays and teaching.

    Abstract [en]

    RlmM (YgdE) catalyzes the S-adenosyl methionine (AdoMet)-dependent 2'O methylation of C2498 in 23S ribosomal RNA (rRNA) of Escherichia coli. Previous experiments have shown that RlmM is active on 23S rRNA from an RlmM knockout strain but not on mature 50S subunits from the same strain. Here, we demonstrate RlmM methyltransferase (MTase) activity on in vitro transcribed 23S rRNA and its domain V. We have solved crystal structures of E. coli RlmM at 1.9 Å resolution and of an RlmM-AdoMet complex at 2.6 Å resolution. RlmM consists of an N-terminal THUMP domain and a C-terminal catalytic Rossmann-like fold MTase domain in a novel arrangement. The catalytic domain of RlmM is closely related to YiiB, TlyA and fibrillarins, with the second K of the catalytic tetrad KDKE shifted by two residues at the C-terminal end of a beta strand compared with most 2'O MTases. The AdoMet-binding site is open and shallow, suggesting that RNA substrate binding may be required to form a conformation needed for catalysis. A continuous surface of conserved positive charge indicates that RlmM uses one side of the two domains and the inter-domain linker to recognize its RNA substrate.

    Abstract [en]

    RlmJ catalyzes the m(6)A2030 methylation of 23S rRNA during ribosome biogenesis in Escherichia coli. Here, we present crystal structures of RlmJ in apo form, in complex with the cofactor S-adenosyl-methionine and in complex with S-adenosyl-homocysteine plus the substrate analogue adenosine monophosphate (AMP). RlmJ displays a variant of the Rossmann-like methyltransferase (MTase) fold with an inserted helical subdomain. Binding of cofactor and substrate induces a large shift of the N-terminal motif X tail to make it cover the cofactor binding site and trigger active-site changes in motifs IV and VIII. Adenosine monophosphate binds in a partly accommodated state with the target N6 atom 7 Å away from the sulphur of AdoHcy. The active site of RlmJ with motif IV sequence 164DPPY167 is more similar to DNA m(6)A MTases than to RNA m(6)2A MTases, and structural comparison suggests that RlmJ binds its substrate base similarly to DNA MTases T4Dam and M.TaqI. RlmJ methylates in vitro transcribed 23S rRNA, as well as a minimal substrate corresponding to helix 72, demonstrating independence of previous modifications and tertiary interactions in the RNA substrate. RlmJ displays specificity for adenosine, and mutagenesis experiments demonstrate the critical roles of residues Y4, H6, K18 and D164 in methyl transfer.

    Abstract [en]

    Background: Coral reefs are colored by eukaryotic chromoproteins (CPs) that are homologous to green fluorescent protein. CPs differ from fluorescent proteins (FPs) by intensely absorbing visible light to give strong colors in ambient light. This endows CPs with certain advantages over FPs, such as instrument-free detection uncomplicated by ultra-violet light damage or background fluorescence, efficient Forster resonance energy transfer (FRET) quenching, and photoacoustic imaging. Thus, CPs have found utility as genetic markers and in teaching, and are attractive for potential cell biosensor applications in the field. Most near-term applications of CPs require expression in a different domain of life: bacteria. However, it is unclear which of the eukaryotic CP genes might be suitable and how best to assay them.

    Results: Here, taking advantage of codon optimization programs in 12 cases, we engineered 14 CP sequences (meffRed, eforRed, asPink, spisPink, scOrange, fwYellow, amilGFP, amajLime, cjBlue, mefiBlue, aeBlue, amilCP, tsPurple and gfasPurple) into a palette of Escherichia coil BioBrick plasmids. BioBricks comply with synthetic biology's most widely used, simplified, cloning standard. Differences in color intensities, maturation times and fitness costs of expression were compared under the same conditions, and visible readout of gene expression was quantitated. A surprisingly large variation in cellular fitness costs was found, resulting in loss of color in some overnight liquid cultures of certain high-copy-plasmid-borne CPs, and cautioning the use of multiple CPs as markers in competition assays. We solved these two problems by integrating pairs of these genes into the chromosome and by engineering versions of the same CP with very different colors.

    Conclusion: Availability of 14 engineered CP genes compared in E coil, together with chromosomal mutants suitable for competition assays, should simplify and expand CP study and applications. There was no single plasmid-borne CP that combined all of the most desirable features of intense color, fast maturation and low fitness cost, so this study should help direct future engineering efforts.

    Importance of Experimental Environmental Conditions in Estimating Risks and Associated Uncertainty of Transgenic Fish Prior to Entry into Nature2019Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 9, artikkel-id 406Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Salmonids show a high degree of phenotypic plasticity that can differ among genotypes, and this variation is one of the major factors contributing to uncertainty in extrapolating laboratory-based risk assessment data to nature. Many studies have examined the relative growth and survival of transgenic and non-transgenic salmonids, and the results have been highly variable due to genotype x environment interactions. The relative survival of fast- and slow-growing strains can reverse depending on the environment, but it is not clear which specific environmental characteristics are driving these responses. To address this question, two experiments were designed where environmental conditions were varied to investigate the contribution of rearing density, food amount, food type, habitat complexity, and risk of predation on relative growth and survival of fast-growing transgenic and slow-growing wild-type coho salmon. The first experiment altered density (high vs. low) and food amount (high vs. low). Density impacted the relative growth of the genotypes, where transgenic fish grew more than non-transgenic fish in low density streams, regardless of food level. Density also affected survival, with high density causing increased mortality for both genotypes, but the mortality of transgenic relative to non-transgenic fish was lower within the high-density streams, regardless of food level. The second experiment altered habitat complexity (simple vs. complex), food type (artificial vs. natural), amount of food (normal vs. satiation), and risk of predation (present vs. absent). Results from this experiment showed that genotype affected growth and survival, but genotype effects were modulated by one or more environmental factors. The effect of genotype on survival was influenced by all examined environmental factors, such that no predictable trend in relative survival of transgenic versus non-transgenic fry emerged. This was primarily due to variations in survival of non-transgenic fish under different environmental conditions (non-transgenic fry had highest survival in hatchery conditions, and lowest survival in complex conditions with natural food fed at a normal level with or without predators). Transgenic fry survival was only significantly influenced by predator presence. The effects of genotype on mass and length were significantly modulated by food type only. Transgenic fry were able to gain a large size advantage over non-transgenic fish when fed artificial food under all habitat types. These experiments support the observations of dynamic responses in growth and survival depending on the environment, and demonstrate the challenge of applying laboratory-based experiments to risk assessment in nature.

    Calabi-Yau manifolds and SU(3) structure2019Inngår i: Journal of High Energy Physics (JHEP), ISSN 1126-6708, E-ISSN 1029-8479, nr 1, artikkel-id 171Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We show that non-trivial SU(3) structures can be constructed on large classes of Calabi-Yau three-folds. Specifically, we focus on Calabi-Yau three-folds constructed as complete intersections in products of projective spaces, although we expect similar methods to apply to other constructions and also to Calabi-Yau four-folds. Among the wide range of possible SU(3) structures we find Strominger-Hull systems, suitable for heterotic or type II string compactifications, on all complete intersection Calabi-Yau manifolds. These SU(3) structures of Strominger-Hull type have a non-vanishing and non-closed three-form flux which needs to be supported by source terms in the associated Bianchi identity. We discuss the possibility of finding such source terms and present first steps towards their explicit construction. Provided suitable sources exist, our methods lead to Calabi-Yau compactifications of string theory with a non Ricci-flat, physical metric which can be written down explicitly and in analytic form.

    Systemic risks with Contingent Convertible Bonds: A simulated study in systemic risks of triggering CoCos in a stressed European banking system.2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Ever since the great financial crisis of 2008 regulators have pushed toward more resilient banks, resulting in more demanding regulation and an increase of regulator’s insight and power. Through the revision of the BASEL framework, Contingent Convertible Bonds were introduced in 2010 as a part of regulatory capital and has since then grown increasingly popular. However, these instruments have never been tested in a stressed European financial system. Hence, there is no genuine information of how these instruments would behave. Neither have there been any published efforts in testing this through simulation, to the best of my knowledge. Using a temporally disaggregated augmentation of the EBA 2016 stress test, I simulate how the financial system would be affected by triggering the CoCos. Studying the implications of both low and high trigger instruments. Results indicate that there are low risks for a systemic fallout and showcases some notable differences as a result of CoCo design and type of trigger.

    Talking through the body. Creating of common world and changing the community through a theatrical performance, a case study.2019Independent thesis Advanced level (degree of Master (Two Years)), 30 poäng / 45 hpOppgave
    Abstract [en]

    This thesis aims to present a practical example of how art can become an instrument capable of investigating, showing and facing a social problem. For doing so, art can overcome communication issues; secondly, it can create a “common world” of shared values that leads to changes in society. The ethnographic example shown here is set among the theatrical company of the KulturParken association (Uppsala, Sweden), which works with people with disability. The fieldwork focuses on the development and staging of their theatrical show “Sagan om Liv och Lust” which deals with the problem of sexuality and disability. The thesis structure follows two main arguments: communication process and evolution in society. The arguments are framed and analysed through the embodied knowledge concept and Turner’s theory about ritual in theatre, as well as through Kester’s dialogical and relational aesthetic theory and Rancière’s Dissensus one. This thesis highlights how disability arts and a disability aesthetic allowed the members of the company to develop a personal awareness, leading them to overcome self-imposed barriers and those imposed by society. Moreover, it shows how the receivers of the theatrical message become active actors themselves, carrying forward the communicative process.

    Search for doubly charged scalar bosons decaying into same-sign W boson pairs with the ATLAS detector2019Inngår i: European Physical Journal C, ISSN 1434-6044, E-ISSN 1434-6052, Vol. 79, nr 1, artikkel-id 58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A search for doubly charged scalar bosons decaying into W boson pairs is presented. It uses a data sample from proton-proton collisions corresponding to an integrated luminosity of 36.1fb-1 collected by the ATLAS detector at the LHC at a centre-of-mass energy of 13TeV in 2015 and 2016. This search is guided by a model that includes an extension of the Higgs sector through a scalar triplet, leading to a rich phenomenology that includes doubly charged scalar bosons H +/-+/-. Those bosons are produced in pairs in proton-proton collisions and decay predominantly into electroweak gauge bosons H +/-+/- W +/- W +/-. Experimental signatures with several leptons, missing transverse energy and jets are explored. No significant deviations from the Standard Model predictions are found. The parameter space of the benchmark model is excluded at 95% confidence level for H +/-+/- bosons with masses between 200 and 220 GeV.

    Search for pairs of highly collimated photon-jets in pp collisions at root s=13 TeV with the ATLAS detector2019Inngår i: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 99, nr 1, artikkel-id 012008Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Results of a search for the pair production of photon-jets-collimated groupings of photons-in the ATLAS detector at the Large Hadron Collider are reported. Highly collimated photon-jets can arise from the decay of new, highly boosted particles that can decay to multiple photons collimated enough to be identified in the electromagnetic calorimeter as a single, photonlike energy cluster. Data from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 36.7 fb(-1), were collected in 2015 and 2016. Candidate photon-jet pair production events are selected from those containing two reconstructed photons using a set of identification criteria much less stringent than that typically used for the selection of photons, with additional criteria applied to provide improved sensitivity to photon-jets. Narrow excesses in the reconstructed diphoton mass spectra are searched for. The observed mass spectra are consistent with the Standard Model background expectation. The results are interpreted in the context of a model containing a new, high-mass scalar particle with narrow width, X, that decays into pairs of photon-jets via new, light particles, a. Upper limits are placed on the cross section times the product of branching ratios sigma x B(X -> aa) x B(a -> gamma gamma)(2) for 200 GeV < m(X) < 2 TeV and for ranges of m(a) from a lower mass of 100 MeV up to between 2 and 10 GeV, depending upon m(X). Upper limits are also placed on sigma x B(X -> aa) x B(a -> 3 pi(0))(2) for the same range of m(X) and for ranges of m(a) from a lower mass of 500 MeV up to between 2 and 10 GeV.

    Search for squarks and gluinos in final states with hadronically decaying tau-leptons, jets, and missing transverse momentum using pp collisions at root s=13 TeV with the ATLAS detector2019Inngår i: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 99, nr 1, artikkel-id 012009Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying tau-lepton is presented. Two exclusive final states with either exactly one or at least two tau-leptons are considered. The analysis is based on proton-proton collisions at root s = 13 TeV corresponding to an integrated luminosity of 36.1 fb(-1) delivered by the Large Hadron Collider and recorded by the ATLAS detector in 2015 and 2016. No significant excess is observed over the Standard Model expectation. At 95% confidence level, model-independent upper limits on the cross section are set and exclusion limits are provided for two signal scenarios: a simplified model of gluino pair production with tau-rich cascade decays, and a model with gauge-mediated supersymmetry breaking (GMSB). In the simplified model, gluino masses up to 2000 GeV are excluded for low values of the mass of the lightest supersymmetric particle (LSP), while LSP masses up to 1000 GeV are excluded for gluino masses around 1400 GeV. In the GMSB model, values of the supersymmetry-breaking scale are excluded below 110 TeV for all values of tan beta in the range 2 <= tan beta <= 60, and below 120 TeV for tan beta > 30.

    Användning av skuggsystem hos organisationer med sanktionerade intranätverk2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Företag och organisationer använder sig ofta av sanktionerade, specialanpassade IT-system för att hantera information och kontrollera sin verksamhet. När anställda frångår policys och riktlinjer kring användningen av dessa system kallas det Shadow IT, eller skuggsystem. Detta innebär att de anställda utvecklar nya rutiner, hård- eller mjukvara eller vänder sig till annan etablerad programvara. Detta arbete innefattar en kvalitativ undersökning där kommunikatörer och informatörer vid Uppsala universitet har intervjuats för en orsaksinventerande studie av skuggsytem i förhållande till universitetets sanktionerade intranät Medarbetarportalen. Orsaker som kunnat fastställas till varför användare frångår rutiner och väljer skuggsystem är bristande reglering, mänskliga faktorer, såsom bekvämlighet och motvilja, brister hos systemets kvalitet samt informationens kvalitet. Vidare orsaker är utvecklingen av mer specifika, bättre egna lösningar i form av olika skuggsystem, samt organisationens struktur och kultur. Då Uppsala universitet påverkas av akademisk frihet och anställdas valmöjligheter i och med detta, saknas tydlig kontroll genom policys och föreskrifter från ledningens sida angående användning.

    AI inom kreativa processer: Möjligheter och utmaningar2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Artificiell intelligens blir allt mer vanligt inom fler och fler områden. Ett område där tekniken är relativt ny är inom kreativa processer och kreativa områden. Detta arbete är en kvalitativ studie av explorativ karaktär, som undersöker hur AI kan användas inom dessa kreativa processer samt vilka möjligheter och utmaningar som uppkommer av det.

    Tre intervjuer har genomförts med personer som har god och aktuell kunskap inom ämnet. Det insamlade materialet har sedan analyserats med den kreativa processen som ramverk. Resultatet visar att AI i vissa steg av processen kan användas, dels för att underlätta men också för att effektivisera densamma. I andra steg har utvecklingen av AI inte kommit tillräckligt långt för att bidra med något värde eller erbjuda någonting som utvecklar eller gör processen lättare. Vidare har resultatet visat att inställningen till användandet kan bli en avgörande faktor för fortsatt utveckling och användning, men även att möjligheterna är fler än utmaningarna.

    Femvertising: feminism i syfte att sälja: en undersökning om konsumenters perspektiv på konceptet femvertising2019Independent thesis Basic level (degree of Bachelor), 20 poäng / 30 hpOppgave
    Abstract [en]

    Femvertising is a relatively new concept that describe the use of feminism in advertising. Femvertising aims to both strengthen the image of women and overrule stereotypical representations of women in advertising, whilst at the same time aims to sell products. This highlights a conflict within the concept, which is what makes femvertising an interesting subject to study. This study investigates the representation of women in contemporary fashion commercials withfemvertising messages. Further, it examines how young Swedish women create meaning in relation to these messages, and finally, how they interpret the conflict within the concept of femvertising.The main material consists of semi-structured interviews with ten young women, the secondary material consists of advertisements from three Swedish fashion brands; H&M, Gina Tricot and Monki. The theoretical framework consists of Stuart Hallsrepresentation theoryand encoding/decoding theory, as well as parts from the consumer cultural framework, a critical view on identity and fashionand finally, two critical theories on feminist messagesin advertisement. Through these theoretical perspectives the study has demonstrated that young female consumers care relatively little about feminist messages in advertising. Instead, consumers want companies to work with feminist values internally and throughout. Further, the results points to that young female consumers want a more including representation of female bodies in advertising and that consumers react in a positive way towards advertising that represents bodies which they can relate to. In conclusion the results suggests that it is not enough for companies to use feminist messages and values in their advertisement, if these messages are not reflected in the company itself.

    Women’s Participation in Peace Negotiations and the Inclusion of Gender Provisions2019Independent thesis Advanced level (degree of Master (Two Years)), 80 poäng / 120 hpOppgave
    Abstract [en]

    Are peace agreements more likely to include gender provisions if women participate in the peace negotiations? The international community, national governments and civil societies around the world have assumed that women’s inclusion in peace negotiations result in higher quality peace agreements, where women’s interests are better taken into consideration. To date, there is a lack of empirical underpinning of the assumption. This study uses a twofold research design, combining statistical and qualitative methods to examine the interrelation between women’s descriptive and substantive representation in peace negotiations in the post-Cold War era. First, the statistical analysis suggests that peace agreements are more likely to include at least one gender provision referring to women’s rights and security if women participate in the negotiation. At the same time, the agreements are not more likely to address a higher number of different areas for increased rights and security measures for women. Second, the qualitative analysis examining the mechanisms shows that there is no guarantee that women will push for gender provisions, but that their particular experiences and interests in conflict, and the expectations from others give them strong reasons to do so. Important factors for women to successfully push for gender provisions have to do both with their individual will and personal ability, and external factors relating to the presence of traditional gender norms and the power balance between men and women in the country of conflict.

    The  foundations  of  EU-citizenship: Liberal  or  Republican?: An analysis of the mores of citizenship promoted by the Court of Justice2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    European citizenship is a concept whose importance has increased since it was introduced in the Maaastricht Treaty. One significant actor, perhaps the most significant actor, for making EU-citizenship into more than a symbolic concept. However, the Court has been criticised, most notably by Fritz Scharpf (2009), for undermining national sovereignty and legitimacy of the Member States and strenghtening the EU’s liberal character, at expense of the republican element in national democracies. This study takes a stand against Scharpf’s portayal of the EU-as an extremely liberal polity by examining six of the Court’s rulings on Union citizenship. It  answers  the  research question:  how closely does  the  EU-citizenship  align with either a  republican or liberal  understanding of citizenship? The results points towards a greater presence of republican mores in EU-citizenship than one might expect and that the Court takes an active role in strengthening republican elements.

    AN ECONOMIC SUPERPOWER WITHOUT AUTHORITY?: An in-depth case study of the European efforts to counter the American-initiated embargo on Iran following the U.S. withdrawal from the Joint Comprehensive Plan of Action2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    It has been written extensively on the EU’s evolving role in the global economy. A mere numeric analysis tells the story about the world’s greatest economic actor that continuously grows in both scope and magnitude. However, due to an increased politicisation of global economic interactions, the matter is not that simple. Scholars agree that the USA, since the end of the Cold War, has been the preeminent actor, arranging, facilitating and maintaining the liberalisation of the global economy. Amongst these scholars, there is a consensus that the EU has developed its position within the framework for which the USA has pioneered and provided. The question is what happens when the USA withdraws from its global commitments and runs a policy counter to fundamental European interests and values? Through a detailed investigation of the European efforts to counter the American withdrawal from the Joint Comprehensive Plan of Action and the reactions from the number of actors affected, I capture the extent to which the EU arrives at operating credibly and autonomously of the USA on an issue of strategic interest. My conclusion is that the EU’s agency in global affairs is restricted by the American position in the increasingly politicised economy. It becomes apparent that the institutional and structural framework within which the EU operates limits the Union’s ability to consolidate its position in global affairs through economic means.

    Discursive Identity Construction in Populism: A Case Study on Fidesz and PiS2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This thesis investigates discursive identity creation used in the discourses of the governing populist political parties of Hungary and Poland, Fidesz and PiS. Considering the important role construction of social identities play in populism, this article argues that we need to enhance our understanding of how the Self and the Other is described and used in populist discourse. The analytical framework draws on earlier literature from the broader field of populism as well as from the fields of Foreign Policy Analysis (FPA), security studies and discourse analysis. In this thesis, the Self is conceptualised as Hungary and Poland, respectively, and the Other is conceptualised as the West. The findings show that Hungary and Poland are depicted as unique, strong and brave, and that “the people” share a common and distinctive culture. Meanwhile, the West is depicted as controlling and not to be trusted. The historical victimization of the nation in relation to the West is important, and used to legitimize the current relationship of the two. Moreover, both discourses use similar rhetoric strategies to defend these identities. However, the analysis also points to differences between the discourse used by PiS and the discourse used by Fidesz, where the latter is more extreme in its identity construction. Hungary is depicted as more unique and the identity of the West entail a more radical degree of Otherness carrying a more direct threat towards the existence of the Hungarian nation. In the discourse used by PiS, on the other hand, the West does pose a threat to the sovereignty of the Polish nation, but Poland simultaneously identifies with and wishes to integrate further with the West. Lastly, the findings show that the discursive identity construction of Hungary, Polandand the West is closely related to new legislation planned or implemented by the parties, and is hence not only a rhetoric device.

    Metabolic Health and Cognitive Function: The Roles of Lifestyle and Shift Work2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The risk of cognitive impairment and metabolic disturbances increases during aging. Healthy lifestyle habits, such as a regular intake of fatty fish and adherence to the Mediterranean diet (MeDi), have been shown to slow age-related cognitive decline and decrease the risk of metabolic disturbances. Conversely, poor lifestyle habits including habitual short sleep duration as well as irregular work schedules (e.g. night shift work) have been correlated with lower cognitive performance and increased risk of having metabolic syndrome (MetS). However evidence is not conclusive regarding the above mentioned associations. The aim of this thesis was to investigate associations of diet, sleep, and shift work with metabolic health or cognitive performance in two Swedish cohorts.

    In Paper I and II we examined whether the dietary intake of omega-3 fatty acids and adherence to MeDi were related to measures of brain health in elderly subjects. To this aim, we used scores from the 7-minute cognitive screening test (7MS) and brain volume determined by magnetic resonance imaging. In Paper I, self-reported dietary intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) at age 70 was positively associated with cognitive performance and global gray matter volume at age 75. In Paper II, the fully-adjusted main analysis revealed that the MeDi score was not linked to measures of brain health. However, low intake of the MeDi component meat and meat products was associated with better performance on the 7MS and larger total brain volume.

    Paper III and IV included subjects aged 45-75 years. In Paper III we demonstrated that current and recent former shift workers (including shifts outside traditional working hours during the past 5 years at the time of the survey) performed worse on the trail making test (TMT) than non-shift workers. The TMT is a test evaluating executive cognitive function, and the performance on this test decreases with age. In Paper IV, sleep duration, sleep disturbances, and sleep-disordered breathing were all linked to an increased prevalence of MetS. Some of the observed associations were age-specific. For example, whereas both short and long sleep durations were linked to a higher prevalence of MetS in younger individuals (<65 years), only long sleep duration did so in the older participants. Collectively, the findings of this thesis suggest that maintaining healthy dietary habits, having high-quality sleep, and following a regular work schedule may be recommended strategies to mitigate age-related morbidities.

    Abstract [en]

    In the present study, we tested whether elderly with a high dietary intake of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) would have higher cognitive test scores and greater brain volume than those with low dietary intake of these fatty acids. Data were obtained from the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) cohort. The dietary intake of EPA and DHA was determined by a 7-day food protocol in 252 cognitively healthy elderly (122 females) at the age of 70 years. At age 75, participants' global cognitive function was examined, and their brain volumes were measured by magnetic resonance imaging (MRI). Three different multivariate linear regression models were applied to test our hypothesis: model A (adjusted for gender and age), model B (additionally controlled for lifestyle factors, e.g., education), and model C (further controlled for cardiometabolic factors, e.g., systolic blood pressure). We found that the self-reported 7-day dietary intake of EPA and DHA at the age of 70 years was positively associated with global gray matter volume (P < 0.05, except for model C) and increased global cognitive performance score (P < 0.05). However, no significant associations were observed between the dietary intake of EPA and DHA and global white matter, total brain volume, and regional gray matter, respectively. Further, no effects were observed when examining cognitively impaired (n = 27) elderly as separate analyses. These cross-sectional findings suggest that dietary intake of EPA and DHA may be linked to improved cognitive health in late life but must be confirmed in patient studies.

    Abstract [en]

    To examine the association between dietary habits, cognitive functioning and brain volumes in older individuals, data from 194 cognitively healthy individuals who participated in the Prospective Investigation of the Vasculature in Uppsala Seniors cohort were used. At age 70, participants kept diaries of their food intake for 1week. These records were used to calculate a Mediterranean diet (MeDi) score (comprising dietary habits traditionally found in Mediterranean countries, e.g. high intake of fruits and low intake of meat), with higher scores indicating more pronounced MeDi-like dietary habits. Five years later, participants' cognitive capabilities were examined by the seven minute screening (7MS) (a cognitive test battery used by clinicians to screen for dementia), and their brain volumes were measured by volumetric magnetic resonance imaging. Multivariate linear regression analyses were constructed to examine the association between the total MeDi score and cognitive functioning and brain volumes. In addition, possible associations between MeDi's eight dietary features and cognitive functioning and brain volumes were investigated. From the eight dietary features included in the MeDi score, pertaining to a low consumption of meat and meat products was linked to a better performance on the 7MS test (P=0.001) and greater total brain volume (P=0.03), i.e. the sum of white and gray matter. Integrating all dietary features of MeDi into score did not explain additional variance. These observational findings suggest that keeping to a low meat intake could prove to be an impact-driven public health policy to support healthy cognitive aging, when confirmed by longitudinal studies. Further, they suggest that the MeDi score is a construct that may mask possible associations of single MeDi features with brain health domains in elderly populations.

    Abstract [en]

    Shift work has been proposed to promote cognitive disturbances in humans; however, conflicting evidence is also present. By using data from 7143 middle-aged and elderly humans (45-75 years) who participated in the Swedish EpiHealth cohort study, the present analysis sought to investigate whether self-reported shift work history would be associated with performance on the trail making test (TMT). The TMT has been proposed to be a useful neuropsychological tool to evaluate humans' executive cognitive function, which is known to decrease with age. After adjustment for potential confounders (e.g., age, education, and sleep duration), it was observed that current and recent former shift workers (worked shifts during the past 5 years) performed worse on the TMT than nonshift workers. In contrast, performance on the TMT did not differ between past shift workers (off from shift work for more than 5 years) and nonshift workers. Collectively, our results indicate that shift work history is linked to poorer performance on the TMT in a cohort of middle-aged and elderly humans.

Methods: Waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting glucose were used to determine MetS status in a cohort (N = 19,691) of middle-aged (aged 45-64 years) and older (aged >= 65 years) subjects. Habitual sleep duration (short, <= 6 h/day; normal, 7-8 h/day; and long >= 9 h/day), sleep disturbances (such as problems with falling and staying asleep), and symptoms of sleep-disordered breathing (SDB, such as snoring and sleep apneas) were measured by questionnaires. Results: Among the participants, 4,941 subjects (25.1%) fulfilled the criteria for MetS. In the entire sample, both short and long sleep durations were associated with higher prevalence of MetS as compared to normal sleep duration. When stratified by age, a similar pattern was observed for middle-aged subjects (<65 years old; prevalence ratio (PR) [95% CI], 1.13 [1.06-1.22] for short sleep and 1.26 [1.06-1.50] for long sleep duration). In contrast, in older individuals (>= 65 years old), only long sleep duration was linked to a higher prevalence of MetS (1.26 [1.12-1.42]; P < 0.01 for sleep duration x age). In the entire cohort, having at least one SDB symptom >= 4 times per week was linked to an increased prevalence of MetS; however, the PR was higher in middle-aged subjects compared with older subjects (1.50 [1.38-1.63] vs. 1.36 [1.26-1.47], respectively; P < 0.001 for SDB x age). Finally, independent of subjects' age, reports of sleep disturbances (i.e., at least one symptom >= 4 times per week) were associated with a higher likelihood of having MetS (1.12 [1.06-1.18]; P > 0.05 for sleep disturbance x age). Conclusion: Our results suggest that age may modify the associations between some sleep parameters and the prevalence of MetS.

    Sharing Responsibility or Protecting Borders?: A Qualitative Analysis of the Development of the Common European Asylum System2019Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Building on three theories of European integration – liberal intergovernmentalism, neofunctionalism and postfunctionalism – I offer an explanation to the process and outcomes of the development of the Common European Asylum System (CEAS) between 2008 and 2018. The process to establish the CEAS has been characterized by clashing actor preferences, which forced actors into negotiations. This thesis aims to analyze the dynamics of these negotiations surrounding the CEAS. My results show that liberal intergovernmentalism explains locked positions in interstate bargaining and highly compromised outcomes, and even non-decisions, of the CEAS. I also argue that neofunctionalism loses explanatory power when sensitive issues concerning automatic quota systems and national sovereignty are discussed, although many arguments by the involved actors in the policy process draw upon neofunctional assumptions. Postfunctionalism is argued to gain explanatory power during recent years, since identityrelated arguments and Eurosceptical and anti-immigrant ideas in European governments have increased.

    Integrationspolitikens utmaningar på kommunal nivå: En studie om immigranter i Sjöbo och Åstorp2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [sv]

    Invandringen till Sverige har ökat de senaste åren och i samband med flyktingkrisen 2015 steg antalet nyanlända dramatiskt. Denna utveckling har orsakat debatt om immigranters rättigheter och krav för integration som staten bör ställa för att utveckla integrationen av immigranter i det svenska samhället. Studier av hur integration fungerar på kommunal nivå har endast gjorts i begränsad omfattning. I och med det faktum att det finns en stark politisk självständighet på kommunal nivå i Sverige, samt att det råder en polarisering mellan politiker är det intressant att studera skillnader i målsättningar och förutsättningar för integration mellan kommuner. Uppsatsen behandlar därför frågan om vilka förutsättningarna är för integration av immigranter. Detta görs genom att studera de två skånska kommunerna Åstorp och Sjöbo som har liknande storlek och geografiskt läge men olika politiska styren. Intervjuer görs med politiker från dessa kommuner och uppsatsen redogör för skillnaderna i integrationspolitiska målsättningar. En kvantitativ analys görs även med hjälp av en enkät som besvarats av immigranter i de två kommunerna. Analysen visar att kommuntillhörighet spelar en viss roll för hur immigranterna upplever mottagandet av deras kultur samt social integration med svenskar. Därutöver visar resultaten att immigranters ursprung, kön, tid i Sverige, uppfattning om religionens betydelse samt upplevda krav på anpassning, förknippas på olika sätt med tillfredställande av deras anspråk för integration, såsom hur de upplever kulturellt mottagande, autonomi, inkludering i olika avseenden samt religiösa rättigheter. En slutsats är att förutsättningarna för integration är starkt förknippade med dessa egenskaper, men att de är relaterade till immigranternas anspråk om rättigheter på olika sätt. Integrationspolitiska åtgärder bör lämpligen ta hänsyn till hur de olika egenskaperna hos immigranterna är relaterade till tillfredställandet av deras anspråk för att därigenom stärka integrationsprocessen.
