    Allt för rikets säkerhet?: En analys av SOU 2024:52 och dess förenlighet med EKMR2025Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is, considering the increased terrorist threat against Sweden, toinvestigate if the terrorist threat falls within the scope of national security in Chapter 2 ofthe Instrument of Government and national security in the European Convention onHuman Rights (ECHR). Furthermore, the aim is to answer the question if the proposal inSOU 2024:52 regarding the amendment of Chapter 2, Section 10 of the Public Order Act,concerning the denial of permits for general assembly on the grounds of national security,is compatible with article 10 and 11 in the ECHR. In answering these questions, both alegal dogmatic and a legal analytical method are employed. The analysis demonstratesthat the terrorist threat is encompassed by both national security in Chapter 2 of theInstrument of Government and the ECHR. Furthermore, it confirms that the proposal toamend Chapter 2, Section 10 of the Public Order Act in SOU 2024:52 is in accordancewith article 10 and 11 in the ECHR.

    Exploring the Practice of HR Analytics: Insights from a Public Sector Context2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Human Resource Analytics (HRA) is a technology-enabled organisational practice that utilises quantitative data and analysis to enhance HR decision-making. While HRA has gained increasing interest among HR practitioners, its adoption has been predominantly concentrated in technology-intensive private sector companies. At the same time, academic research on HRA remains limited, particularly in the public sector. Although factors such as low technological maturity and a lesser focus on profit maximisation and competitive advantage may hinder its implementation, HRA holds significant potential for public sector organisations due to their distinct characteristics. These include large workforces generating extensive HR-related data, political authority, governmental ownership, and a strong emphasis on transparency, accountability, and efficiency in areas such as competence supply, workforce recruitment, and retention.This thesis comprises four papers that collectively conceptualise and investigate the practice of HRA, exploring the reasons, preconditions, and processes involved in its implementation within public sector organisations. Empirical data were collected from three Swedish public sector organisations at the national, regional, and local levels. The study employs an engaged scholarship research design, allowing for the pragmatic application of multiple theoretical perspectives best suited to address the overarching research question: How is HRA being implemented in public sector organisations? This research aims to contribute to the existing HRA literature while also offering practical insights for organisations and HR practitioners operating in this under-researched context.By adopting a practice-based approach, informed by institutional legitimacy concept, the AMO (Ability, Motivation, Opportunity) framework, and organisational translation perspective, this thesis reveals that HRA practices undergo significant adaptation during implementation. In the public sector, HRA has primarily been limited to improving HR reporting and the visualisation of descriptive HR data. HRA practitioners, driven by contextual factors and the need to ensure the legitimacy of HR activities through economic rationality, face constraints related to analytical skills, organisational resources, and sector-specific characteristics.Given the rapid advancements in technology, including the growing influence of AI, future research should explore how these developments, alongside challenges such as employee privacy and data protection, impact the further evolution of HRA practices in the public sector.

    2023 (English)In: Journal of Organizational Effectiveness, ISSN 2051-6614, E-ISSN 2051-6622, Vol. 12, no 5, p. 83-111Article, review/survey (Refereed) Published
    Abstract [en]

    PurposeHuman resource analytics (HRA) is an HR activity that companies and academics increasingly pay attention to. Existing literature conceptualises HRA mostly from an objectivist perspective, which limits understanding of actual HRA activities in the complex organisational environment. This paper therefore draws on the practice-based approach, using a novel framework to conceptualise HRA-as-practice.Design/methodology/approachThe authors conducted a systematic literature review of 100 academic and practitioner-oriented publications to analyse existing HRA literature in relation to practice theory, using the "HRA-as-practice" frame.FindingsThe authors identify the main practices involved in HRA, by whom and how these practices are enacted, and reveal three topics in nomological network of HRA-as-practice: HRA technology, HRA outcomes and HRA hindrances and facilitators, which the authors suggest might actualize enactment of HRA practices.Practical implicationsThe authors offer HR function and HR professionals a basic ground to evaluate HRA as a highly contextual activity that can potentially generate business value and increase HR impact when seen as a complex interaction between HRA practices, HRA practitioners and HRA praxis. The findings also help HR practitioners understand multiple factors that influence the practice of HRA.Originality/valueThis systematic review differs from the previous reviews in two ways. First, it analyses both academic and practitioner-oriented publications. Second, it provides a novel theoretical contribution by conceptualising HRA-as-practice and comprehensively compiling scattered topics and themes related to HRA.

    Abstract [en]

    Purpose

    This study explores the rationale behind the utilisation of human resource (HR) analytics in public sector organisations. The existing HR analytics literature exhibits limited empirical evidence and has predominantly focused on the business context of private firms. In addressing this gap, the study seeks to answer the following research question: What reasons for the adoption of HR analytics can be identified in public sector organisations?

    Design/methodology/approach

    The study employs a qualitative approach drawing on the empirical data collected from three public administrations in Sweden - national, regional and local. A total of 51 in-depth interviews are conducted with HR and other organisational practitioners engaged in HR analytics practices.

    Findings

    Drawing on the institutional legitimacy perspective, this paper suggests that public sector organisations adopt HR analytics to secure cognitive, socio-political and technological legitimacy, stemming from explanations rooted in economic rationality. This encompasses organisational and HR-related outcomes achieved through data management and analysis, driven by the personal interests of specific individuals.

    Research limitations/implications

    This study contributes to ongoing debates about the adoption of HR analytics in diverse contextual settings. Future research is needed in other organisational contexts, including various national and international settings.Practical implicationsThe results of this study offer practical insights for HR practitioners in public sector organisations seeking to adopt HR analytics to enhance organisational and HR legitimacy.

    Originality/value

    This study contributes to the HR analytics literature by providing empirical evidence from the public sector. Furthermore, it advocates for a synthesis of economic rationality with legitimacy gains and individual interests to elucidate the rationale behind the adoption of HR analytics.

    (English)Manuscript (preprint) (Other academic)
    Abstract [en]

    The topic of human resource (HR) analytics has recently attracted increasing interest. Despite its numerous advantages, the adoption of HR analytics remains limited, particularly within the public sector. This study aims to explore the reasons behind this limitation. It applies the Ability, Motivation, and Opportunity (AMO) framework to examine the preconditions for HR analytics among HR professionals in the public sector. The study is based on 30 interviews with HR practitioners from three public administration authorities in Sweden, analysed using thematic template analysis. The findings reveal that although HR practitioners are highly motivated to align with government agendas, enhance decision-making, and ensure transparency, they face significant barriers. These include a lack of analytical skills and technical knowledge, limited data availability, inadequate technical support, scarce resources, and complex organisational structures. This study contributes to the growing HR analytics literature by highlighting the complexity involved in HR analytics adoption in the public sector context.

    (English)Manuscript (preprint) (Other academic)
    Abstract [en]

    The study examines the implementation of human resource analytics (HRA) within the context of public sector organisations, drawing upon the organisational translation perspective. We conduct a longitudinal process study of real-time HRA implementation projects in two public sector organisations in Sweden. The findings reveal that the content of the HRA concept undergoes significant transformation during the translation process, with components being copied, omitted, added, and altered. As a result, HRA in practice diverges substantially from its original idea. The study identifies three translation patterns: alignment to the needs of final users, technological determinism, and organisational complexity. We argue that these translation patterns may explain the outcomes from the unique translation processes. The study contributes to the organisational translation literature by integrating principles of heterogeneity and homogeneity of translation results. Additionally, it provides empirical evidence to the field of HRA, enhancing understanding of HRA in public sector organisations.

    Fullgörelse som påföljd vid dröjsmål på säljarens sida: Köparens rätt att hålla fast vid köp i händelse av dröjsmål och säljarens möjligheter att befrias från fullgörelseplikten enligt köplagen (1990:931)2024Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    I detta rättsvetenskapliga arbete behandlas fullgörelsepåföljden vid dröjsmål på säljarens sida enligt köplag (1990:931). Särskilt fokus ligger på köparens rätt att hålla fast vid köpet. Syftet med arbetet är att utreda de förutsättningar under vilka säljaren kan befrias från sin fullgörelseplikt. I arbetet görs därför en genomgång av förpliktelser, dröjsmålsbegreppet, fullgörelsepåföljden samt möjligheten att befrias från fullgörelseplikten. Ett dröjsmål på säljarens sida uppstår när denne inte presterar i enlighet med de villkor som i köpavtalet ställts upp för avlämnandetidpunkten. Utgångspunkten är principen ompacta sunt servanda, vilken innebär att avtal ska hållas. Samtidigt erkänner rättsordningen att det kan finnas situationer där fullgörelse inte bör kunna krävas, exempelvis vid hinder som säljaren inte kan övervinna eller när fullgörelse skulle medföra orimliga uppoffringar. Analysen omfattar en genomgång av fullgörelsebestämmelser i både äldre och gällande rätt. Vidare granskas rättspraxis och doktrin för att klargöra hur rekvisiten förbefrielse från fullgörelseplikten ska tolkas. Slutsatsen som dras är att fullgörelseplikten i svensk köprätt är starkt förankrad och att befrielsereglerna ska tillämpas restriktivt. Vidare ska reglerna bedömas med utgångspunkt i omständigheterna i det enskilda fallet. En säljare bör därför utnyttja lagens dispositiva karaktär för att begränsa sin egen risk.

    Abstract [en]

    This thesis examines how the amendments to the Swedish Parental Code (föräldrabalken), which came into effect on January 1 2025, may influence the formal and substantive reasoning in cases concerning custody, residence, and visitation. Special focus is given to cases involving allegations of violence or other forms of abuse against either a parent or a child. The thesis also aims to analyze whether the reasoning in judgments can contribute to achieving the overall purpose of the amendments – namely, strengthening the protection of children.

    In order to address the research questions, a legal doctrinal method is applied, analyzing legal sources such as statutes, preparatory works, case law, and doctrinal writings. The thesis identifies a distinction between what must and what should be included in the reasoning in custody cases. Whether the best interest of the child is classified as a legal fact or as a complex legal fact, as well as whether the circumstances included in the assessment of the child’s best interest are regarded as legal facts or evidentiary facts, is of essential importance.

    The results indicate that the amendments, by prioritizing the risk of violence over the contact principle and by introducing an obligation to obtain expert opinions in certain cases, can lead to a more detailed account of risk assessment and justification in the reasoning. This has the potential to enhance the protection of children and lead to more well-founded decisions. At the same time, it is noted that the legal consequences of deficient reasoning are limited, making the courts’ interpretation and application of legal facts and evidentiary facts crucial for the practical impact of the amendments.

    Abstract [en]

    This essay examines the allocation of the right to deduct input value added tax (VAT) in projects involving the construction of residential buildings and garages. While there is no right to deduct input VAT for the construction of residential buildings, there is a right to deduct input VAT for the construction of parking spaces and garages. The central issue concerns how costs should be allocated in cases of comprehensive construction projects of both residential buildings and garages. The study systematically reviews all lower court case law to identify patterns in legal application. The analysis reveals inconsistencies in how input VAT allocation is applied. Furthermore, the essay discusses whether the current legal practice aligns with EU law. The application of the law is critically assessed, and it is suggested that the Supreme Administrative Court should review the issue to ensure greater consistency and legal clarity.

    Kulturrättens historia: Disciplinen som aldrig blev?2025Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Det brukar sägas att politiken ligger nedströms från kulturen. En jurist menar i sin tur troligtvis att juridiken ligger nedströms från politiken. Många juridiska frågeställningar och rättsområden, inte minst den konstitutionella rätten, kretsar kring hur juridik och politik bör förhålla sig till varandra. Det finns ingen brist på diskussioner, debattartiklar och publikationer som diskuterar hur dessa intresseområden bör balansera och reglera varandra. Söker man däremot efter åsikter  kring hur juridiken bör förhålla sig till kulturen så möts man av en mycket underlig tystnad. En snabb sökning  efter kulturrätt på de stora svenska universitetsbibliotekens söktjänster så ges nästan inga sökträffar. Om det ligger någon sanning i att politiken förhåller sig till kulturen och att juridiken i sin tur förhåller sig till politiken så framstår det som oerhört märkligt att så pass lite forskning och diskussioner har förts längre uppströms än politikens flodbanker. Inom den politiska sfären finns det desto fler ivriga debatter kring den politiska sidan av kulturen: nämligen kulturpolitiken. Den senaste tiden har även fört med sig en del utveckling på det kulturpolitiska området och området har ännu en gång blivit föremål för vilda diskussioner. Ett färskt exempel är regeringens förslag om att införa en ny kulturkanon. Förslaget har fört kulturpolitiken upp till ytan igen och det är tydligt att det råder delade meningar om hur kulturpolitiken i praktiken bör utformas. Inom den juridiska sfären är det däremot förhållandevis tyst. Det verkar nästan som att den samhällspolitiska läran om politikens avstånd till kulturen indirekt verkar avskräcka juridikens intrång på kulturområdet. Sannerligen, om till och med politiken bör träda varsamt på kulturens område, hur kan juridiken i sin tur ha någon rätt att inkräkta på dess domän? Den här uppsatsen kommer därför göra ett djärvt försök att göra just det, inkräkta på det nästintill outforskade kulturområdets anknytning till juridiken: kulturrätten.

    Lärares erfarenheter och upplevelser av digitala hjälpmedel i skolan, för elever med läs- och skrivsvårigheter: En kvalitativ intervjustudie2025Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studiens syfte är att undersöka lärares upplevelser och erfarenheter av att använda digitala verktyg inom undervisningen för elever med läs- och skrivsvårigheter. Detta arbete genomfördes genom kvalitativa intervjuer av lärare som har varit verksamma i svenska grundskola inom årskurserna 4–6. Analysen av intervjuerna genomförs genom en tematisk analys med utgångsteorier från sociokulturell teori samt didaktisk teori. Resultatet visade att respondenterna fann att digitala verktyg är ett viktigt hjälpmedel för elever med läs- och skrivsvårigheter och att det finns många möjligheter till att använda de för att hjälpa elever att delta i ordinarie undervisning. Samtidigt finner respondenterna att de funderar över digitala verktygens påverkan på elever inom aspekterna av skärmtid samt om det bidrar till en förbättring av elevernas läs- och skrivförmågor. I diskussionen presenteras respondenternas upplevelser kopplat till relevant forskning inom ämnet och i konklusionen ges en uppmaning till vidare forskning inom ämnet samt förslag för vidare undersökningar.

    Samspelet mellan verbaltext och bild: En sociosemiotisk läromedelsanalys av SO-läromedel för åk 1-32025Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att undersöka hur verbaltext och bild förhåller sig till varandra i två olika läromedel i de samhällsorienterande ämnena avsedda för årskurs 1–3. Studien utgår från den sociosemiotiska teorin där lärande framträder som en social och kommunikativ process, där människor skapar mening genom att använda sig av olika semiotiska modaliteter för att förmedla innehåll. Metoden som används för att besvara studiens syfte och frågeställningar är en multimodal analys. Studiens analysmodell är en modell för ämnesdidaktiskt arbete med multimodala texter. Resultatet visar att det finns ett tydligt samspel mellan verbaltext och bild i läroböckerna som analyserats. Vidare framkom det i resultatet att rumslig närhet identifierats och att båda läroböckerna förhåller sig väl till kongruensprincipen. I kontrast till detta framkom det att färgmässig närhet inte förekom i läroböckerna. Slutsatsen som dras i studien är att samspelet mellan verbaltext och bild i läroböckerna påverkar elevernas förståelse och det är av stor vikt att lärare har kunskap om hur multimodalitet kan påverka lärandet och förståelsen av ett ämnesinnehåll.

    Reclaiming tradition as critique of oppression2021In: Contextual Theology: Skills and Practices of Liberating Faith / [ed] Bergmann, S Vahakangas, M, Routledge, 2021, p. 126-137Chapter in book (Refereed)
    Abstract [en]

    This chapter sets out to discuss if, why, and how theology should be used for critique of and resistance to oppression. Shariati understands Islam as an ideology, in the Gramscian sense of a worldview that can demystify oppressive relations and make resistance possible. Shariati claims that concepts such as oppression, justice, and righteous leadership receive their most lucid articulations in Islamic tradition. The first set of reasons centres around the fact that theology, or religious tradition, is the tradition of the poor. A comparison of these writers also brings into focus what traditions can bring to reasoning as an endeavour. A certain stringency of method might be the prerequisite for allowing tradition to exert its resistance, to realise the critical and transformative potential of tradition. Traditions form conditions of thought, which become evident in lingering emphases, directions taken, perspectives adopted, and the specific shape of the solutions to certain intricate problems.

    On the Quantitative Evaluation and Enhancement of Prehospital Decisional Capacity2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Prehospital care involves increasingly complex decision-making processes, necessitating commensurate advances in the methods used to assess and improve the quality of patient triage processes. This doctoral project aimed to advance the measurement of patient outcomes in the evaluation of prehospital decision-making and develop interventions to improve those outcomes. In study I, a set of outcome definitions for evaluating referrals to non-emergency care by dispatch nurses was validated, confirming the ability of systematic data abstraction processes to identify patient harms missed by traditional incident reporting systems. In study II, an intervention delivering feedback on process and outcome metrics to dispatch nurses was evaluated, identifying improvements in some process metrics, while impacts on outcomes remained elusive. In study III a machine learning-based approach to estimating composite risk scores was validated internally for use in prehospital contexts. In study IV, similar models for use in Ambulance care were externally validated in a dataset collected from six Swedish regions, finding that model performance remained superior to traditional rule-based risk assessment instruments even when the models were applied in novel settings. Study V is a randomized controlled trial whereby a clinical decision support tool based on these models was found to enhance the ability of dispatchers to identify and prioritize high-risk patients in resource constrained situations. Future directions for study include the incorporation of additional structured and unstructured data in the prediction models, and efforts to evaluate and enhance their fairness and alignment with human assessments of care need. Open-source software packages implementing these tools are available to enhance the transparency of the work and stimulate further development.

    Abstract [en]

    Objectives: This study aimed to assess whether trigger tools were useful identifying triage errors among patients referred to non-emergency care by emergency medical dispatch nurses, and to describe the characteristics of these patients.

    Design: An observational study of patients referred by dispatch nurses to non-emergency care.

    Setting: Dispatch centres in two Swedish regions.

    Participants: A total of 1089 adult patients directed to non-emergency care by dispatch nurses between October 2016 and February 2017. 53% were female and the median age was 61 years.

    Primary and secondary outcome measures: The primary outcome was a visit to an emergency department within 7 days of contact with the dispatch centre. Secondary outcomes were (1) visits related to the primary contact with the dispatch centre, (2) provision of care above the primary level (ie, interventions not available at a typical local primary care centre) and (3) admission to hospital in-patient care.

    Results: Of 1089 included patients, 260 (24%) visited an emergency department within 7 days. Of these, 209 (80%) were related to the dispatch centre contact, 143 (55%) received interventions above the primary care level and 99 (38%) were admitted to in-patient care. Elderly (65+) patients (OR 1.45, 95% CI 1.05 to 1.98) and patients referred onwards to other healthcare providers (OR 1.58, 95% CI 1.15 to 2.19) had higher likelihoods of visiting an emergency department. Six avoidable patient harms were identified, none of which were captured by existing incident reporting systems, and all of which would have received an ambulance if the decision support system had been strictly adhered to.

    Conclusion: The use of these patient outcomes in the framework of a Global Trigger Tool-based review can identify patient harms missed by incident reporting systems in the context of emergency medical dispatching. Increased compliance with the decision support system has the potential to improve patient safety.

    2025 (English)In: BMJ Open Quality, E-ISSN 2399-6641, Vol. 14, no 1, article id e002993Article in journal (Refereed) Published
    Abstract [en]

    Background: Clinical feedback is often lacking in prehospital care, and while performance data is increasingly available to clinical and operational leadership, it is seldom made available to care providers themselves. In this study, we investigate the impact of a simple intervention consisting of the provision of monthly feedback reports via email to emergency medical dispatch nurses in three Swedish regions.

    Method: Individualised reports consisting of 14 measures divided into descriptive (eg, priority-setting and call times), process (eg, dispatch times and documentation completeness) and outcome (eg, over/under triage rate) categories were developed with staff and management input. Report delivery was implemented using a stepped-wedge design, and effects were evaluated using a hierarchical regression-based interrupted time series analysis.

    Results: 40 dispatchers were included in the study between March 2020 and October 2023, who handled a total of 246 353 incidents. Some impacts on documentation-related process measures were identified, with the odds of complete documentation increasing by 7.5% (95% CI 5.1 to 9.9) and the odds of having a documented contact reason increasing by 3.8% (1.5-5.9). These effects remained robust over the post-intervention period. Weaker impacts on outcome measures were identified which could be explained by a higher priority given to emergency medical dispatches overall.

    Conclusion: Providing performance data can influence care providers to adjust their behaviour to improve process-related quality metrics under their direct control. The intervention may also have induced nurses to more often upgrade the priority of their patients. Improving outcome metrics may however require more intensive, multifaceted interventions.

    2019 (English)In: PLOS ONE, E-ISSN 1932-6203, Vol. 14, no 12, article id e0226518Article in journal (Refereed) Published
    Abstract [en]

    BACKGROUND: The triage of patients in prehospital care is a difficult task, and improved risk assessment tools are needed both at the dispatch center and on the ambulance to differentiate between low- and high-risk patients. This study validates a machine learning-based approach to generating risk scores based on hospital outcomes using routinely collected prehospital data.

    METHODS: Dispatch, ambulance, and hospital data were collected in one Swedish region from 2016-2017. Dispatch center and ambulance records were used to develop gradient boosting models predicting hospital admission, critical care (defined as admission to an intensive care unit or in-hospital mortality), and two-day mortality. Composite risk scores were generated based on the models and compared to National Early Warning Scores (NEWS) and actual dispatched priorities in a prospectively gathered dataset from 2018.

    RESULTS: A total of 38203 patients were included from 2016-2018. Concordance indexes (or areas under the receiver operating characteristics curve) for dispatched priorities ranged from 0.51-0.66, while those for NEWS ranged from 0.66-0.85. Concordance ranged from 0.70-0.79 for risk scores based only on dispatch data, and 0.79-0.89 for risk scores including ambulance data. Dispatch data-based risk scores consistently outperformed dispatched priorities in predicting hospital outcomes, while models including ambulance data also consistently outperformed NEWS. Model performance in the prospective test dataset was similar to that found using cross-validation, and calibration was comparable to that of NEWS.

    CONCLUSIONS: Machine learning-based risk scores outperformed a widely-used rule-based triage algorithm and human prioritization decisions in predicting hospital outcomes. Performance was robust in a prospectively gathered dataset, and scores demonstrated adequate calibration. Future research should explore the robustness of these methods when applied to other settings, establish appropriate outcome measures for use in determining the need for prehospital care, and investigate the clinical impact of interventions based on these methods.

    Att navigera mellan tradition och innovation: En enkätstudie om lärares undervisningsmetoder i samhällskunskap och utmaningar som kommer med detta2025Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Undervisningen inom samhällskunskapen präglas av både möjligheter och utmaningar sett till Skolverkets breda centrala innehåll inom ämnet, både inom grundskolan och gymnasiet. Kan undervisningen se olika ut beroende på lärare och kan detta grunda sig i hur de olika undervisningsmetoderna, traditionell undervisning, aktivt lärande och öppet klassrumsklimat kombineras? Studien syftar att genom en enkätstudie med samhällskunskapslärare undersöka, både kvalitativt samt kvantitativt, vilka undervisningsmetoder som lärare använder sig av och hur dessa kombineras inom samhällskunskapsundervisningen.Vidare syftar studien att undersöka vilka utmaningar som uppstår när undervisningsmetoder kombineras och om detta kan tolkas utifrån lärares erfarenhet. 

    Uppsatsen utgår ifrån Martens & Gainous (2013) studie som undersöker vilka undervisningsmetoder som lärare använder sig av i USA inom samhällskunskapen och vad som funkar. Denna egenförfattade studie visar att det finns fyra tydliga utmaningar: kunskapsnivå, social nivå, struktur och tidsbrist i kombinerandet av undervisningsmetoder. Dessa fyra utmaningar kan i sin tur förstås och kopplas till lärarens erfarenhet och att det finns en skillnad mellan oerfarna lärare och mer erfarna. Studien visar att valet och kombinationen av undervisningsmetoder i samhällskunskapsundervisningen kan förstås utifrån de utmaningar som de responderande lärarna svarat men även vilka tillvägagångssätt som lärarna utgår ifrån i sin undervisning. Beroende på hur läraren kombinerar undervisningsmetoderna i sin undervisning så skapas olika utmaningar och detta kan dels tolkas utifrån lärares erfarenhet.

    American Exceptionalism in Presidential Rhetoric 2001-2024: Continuity or Change?2025Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    American Exceptionalism has demonstrated significant staying power in political and academic discourse and has been reinterpreted throughout history. This thesis investigates the change or continuity of American Exceptionalism (AE) in Republican and Democratic presidential rhetoric from 2001-2024. A descriptive idea analysis is conducted on the annual State of the Union addresses (SOTU) of four presidents: George W. Bush, Barack Obama, Donald Trump, and Joseph Biden. The analysis considers both domestic and foreign policy elements in the speeches, drawing on a typology of AE that divides exceptionalism into two primary categories: inward and outward exceptionalism. The aim is to identify the dominant type of exceptionalism across the four presidencies, compare between political parties, and determine whether there is change or continuity in AE types over time. The results indicate no consistent change or continuity of American Exceptionalism. Instead, the study reveals the dynamic nature of AE, with greater divergences occurring between political parties and more significant convergences of AE types existing within parties.

    Victim blaming as collateral damage: professionals on court hearings in cases of rape, assault, and fraud2025In: Journal of law and society, ISSN 0263-323X, E-ISSN 1467-6478Article in journal (Refereed)
    Abstract [en]

    This study investigates legal professionals’ understanding of the attribution of moral guilt to complainants in court hearings, comparing rape, assault, and fraud cases in Sweden.

    Sixteen semi-structured interviews were conducted with judges, prosecutors, defence lawyers, and complainants’ counsels.

    The findings suggest that while professionals assert that attributions of moral guilt to complainants are rare, complainants may perceive blame due to misinterpretation of legally relevant questions. Undue attribution of moral guilt occasionally occurs, particularly during defence cross-examination. Strategies to mitigate the risk of blame include ensuring that hearings are respectful and fact oriented, addressing victim-blaming issues in professional development courses, and preparing complainants prior to hearings. In our study, the attribution of moral guilt predominantly centred on rape cases, which may be due to historical discourse and sensitivity surrounding sexual assault cases.

    The study highlights the need for further research into mechanisms of attributing moral guilt to complainants and into sources of tension that contribute to negative experiences for complainants.

    Bridging War and Governance: The Role of Rebel Integration in Peace Agreement Stability2025Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study explores how provisions for rebel integration into government affect the durability of peace agreements. Based on models of power-sharing, peacebuilding, and spoiler dynamics, the paper investigates whether former rebel groups in governance diminish the risk of peace agreement termination. Based on a logistic regression analysis of 210 peace agreements drawn from the Uppsala Conflict Data Program (UCDP) Peace Agreement Dataset (1975–2021), the study shows that peace settlements with explicit provisions for rebel integration are linked to a lower risk of agreement termination. When rebels are integrated into government systems, the incentive to undermine agreements reduces, making it more likely that peace will hold, the findings suggest. But the analysis also identifies powerful destabilizing factors, like provisions for foreign troop withdrawals, which strongly correlate with higher termination risks. Lastly, commissions in charge of implementation, that is highly anticipated to make peace agreements more durable, also display little statistical significance in predicting durability of agreement. Such insights contribute to the post-conflict governance literature by stressing the importance of institutionalized rebel participation for sustaining peace. The study indicates that more long-term studies on the political implications of the integration of rebels are needed and that future studies should test additional control variables, use different mediation and modeling techniques, and include mixed-methods approaches to better support causal claims.

    On Population Design: Using Migration Law to Dismantle Constitutional Democratic Institutions2022In: Migrants' Rights, Populism and Legal Resilience in Europe / [ed] Vladislava Stoyanova; Stijn Smet, Cambridge: Cambridge University Press, 2022, p. 70-93Chapter in book (Refereed)
    Abstract [en]

    This chapter argues that in order to understand the linkages between populism and restrictions of migrants’ rights, more awareness is needed of the distinction between empirical facts and institutional facts. If the distinction is disregarded, negative consequences can follow. The chapter explains that mobility – the movement of bodies through space – is the empirical fact to which the law attaches a series of legal concepts by way of institutional facts (e.g. citizenship, residence, population, and migration). The chapter demonstrates that, once aware of the distinction, we are better equipped to see how legal regulations governing the institutional fact of population affect our social and constitutional identity. Migration law and policy ultimately impact on the composition of the institutional fact of the People (those who count as citizens) and its role in the constitutional order (what the citizens do, which rights and duties they have), that determines the state’s constitutional identity. Therefore, as this chapter argues, migration law can be employed to both strengthen and dismantle constitutional democratic institutions. Migration lawyers thus have much to offer to constitutional lawyers who are concerned about the contemporary resilience of the constitutional setting.

    Studies of human pancreatic innate immunity and microvasculature in the context of diabetes pathophysiology2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Diabetes is a set of chronic diseases characterized by hyperglycemia and pancreatic dysfunction. The pancreas consists of two tissue compartments with highly distinct functions – hormone-producing islets of Langerhans and acinar tissue with an exocrine function. Improved understanding of immune processes and stromal cells within the compartments of the pancreas may highlight important specializations, which could lead to novel insights into islet dysfunction in diabetes or islet transplantation. Thus, in this thesis the properties of pancreatic innate immunity and microvascular endothelial cells were compared between islet- and exocrine tissue from human organ donors. 

    Enteroviral infection has been suggested to trigger development of type 1 diabetes. In paper I, the feasibility of using innate immunity viral sensor protein kinase R (PKR) as evidence of enteroviral infection in the pancreas was examined. A general PKR expression was found at protein and RNA level in islets and exocrine tissue under basal conditions, and in vitro infection of islets with enterovirus did not lead to distinct PKR expression. This suggests that PKR expression should not be used to corroborate enteroviral infection in the human pancreas. In paper II, gene expression profiles were generated and compared between microvascular endothelial cells (MVECs) from islets and exocrine tissue. Gene sets involved in vascular- and endothelial development were enriched in islet MVEC samples. This suggests increased vascular proliferation within islets, potentially consistent with tissue remodeling. In paper III, gene expression profiles were generated and analyzed in CD206- and CD206+ macrophages from islets and exocrine tissue. Gene sets involved in inflammation and glycolysis were enriched in CD206- macrophages, while gene sets involved in complement, scavenging and immune regulation were enriched in CD206+ macrophages. In comparisons between tissues, a few immune regulation-associated gene sets were enriched in islet macrophages while gene sets associated with proinflammatory functions and extracellular matrix were enriched in exocrine macrophages. 

    The main findings in this thesis were that expression of PKR is poor evidence of viral infection in the pancreas, identification of islet-MVEC gene expression consistent with intraislet vascular remodeling, and a characterization of global gene expression in two subgroups of macrophages in islets and in exocrine tissue.

    Abstract [en]

    Viral infection of the insulin-producing cells in the pancreas has been proposed in the etiology of type 1 diabetes. Protein kinase R (PKR) is a cytoplasmic protein activated through phosphorylation in response to cellular stress and particularly viral infection. As PKR expression in pancreatic beta-cells has been interpreted as a viral footprint, this cross-sectional study aimed at characterizing the PKR expression in non-diabetic human pancreases. PKR expression was evaluated in pancreas tissue from 16 non-diabetic organ donors, using immunohistochemistry, qPCR, and western blot. Immunohistochemistry and western blot showed readily detectable PKR expression in the pancreatic parenchyma. The qPCR detected PKR mRNA in both endocrine and exocrine samples, with a slightly higher expression in the islets. In conclusion, PKR is constitutively expressed in both endocrine and exocrine parts of the pancreas and its expression should not be interpreted as a viral footprint in pancreatic beta cells.

    Abstract [en]

    In experimental studies, pancreatic islet microvasculature is essential for islet endocrine function and mass, and islet vascular morphology is altered in diabetic subjects. Even so, almost no information is available concerning human islet microvascular endothelial cell (MVEC) physiology and gene expression. In this study, islets and exocrine pancreatic tissue were acquired from organ donors with normoglycemia or impaired glucose metabolism (IGM) immediately after islet isolation. Following single-cell dissociation, primary islet- and exocrine MVECs were obtained through fluorescence-activated cell sorting (FACS) and transcriptional profiles were generated using AmpliSeq. Multiple gene sets involved in general vascular development and extracellular matrix remodeling were enriched in islet MVEC. In exocrine MVEC samples, multiple enriched gene sets that relate to biosynthesis and biomolecule catabolism were found. No statistically significant enrichment was found in gene sets related to autophagy or endoplasmic reticulum (ER) stress. Although ample differences were found between islet- and exocrine tissue endothelial cells, no differences could be observed between normoglycemic donors and donors with IGM at gene or gene set level. Our data is consistent with active angiogenesis and vascular remodeling in human islets and support the notion of ongoing endocrine pancreas tissue repair and regeneration even in the adult human.

    Abstract [en]

    Macrophages reside in all organs and participate in homeostatic- and immune regulative processes. Little is known about pancreatic macrophage gene expression. In the present study, global gene expression was characterized in human pancreatic macrophage subpopulations. CD206- and CD206 + macrophages were sorted separately from pancreatic islets and exocrine tissue to high purity using flow cytometry, followed by RNA-seq analysis. Comparing CD206- with CD206 + macrophages, CD206- showed enrichment in histones, proliferation and cell cycle regulation, glycolysis and SPP1-associated immunosuppressive polarization while CD206 + showed enrichment in complement and coagulation-, IL-10 and IL-2RA immune regulation, as well as scavenging-related gene sets. Comparing islet CD206- with exocrine CD206-, enrichments in islet samples included two sets involved in immune regulation, while enrichments in exocrine samples included sets related to extracellular matrix and immune activation. Fewer differences were found between CD206 + macrophages, with enrichments in islet samples including two IL2-RA related gene sets, while enrichments in exocrine samples included sets related to extracellular matrix and immune activation. Comparing macrophages between individuals with normoglycemia, elevated HbA1c or type 2 diabetes, only a few diverse differentially expressed genes were identified. This work characterizes global gene expression and identifies differences between CD206- and CD206 + macrophage populations within the human pancreas.

    Next generation CD40 targeting immunotherapy: Development of antibody-based personalized cancer treatment2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Antibody-based therapeutics have revolutionised the field of immune-oncology and other diseases with their diverse targeted effects. Immune-stimulatory antibodies, such as agonistic CD40 antibodies, have shown promising preclinical results in inducing specific anti-tumour responses. This thesis presents the development of a novel bispecific antibody platform based on agonistic CD40 antibodies designed to enable flexible peptide cargo delivery.

    In paper I, the design of a tetravalent bispecific antibody platform based on two well-established agonistic anti-CD40 antibodies was evaluated. The bispecific antibodies retained their agonistic activity and demonstrated high-affinity binding to a defined peptide tag, enabling efficient intracellular peptide antigen delivery. This affinity binding was crucial for inducing antigen-specific T cell proliferation in vivo. The lead candidate identified in paper I was further assessed for large-scale production in paper II, using the PiggyBack transfection system to generate a stable cell pool. Optimisation of nutrients and feeding schedules allowed for large-scale bioreactor culturing, followed by purification and quality analysis. 

    In paper III, a novel set of anti-CD40 antibodies was generated through phage display, and the lead antibody clone, which exhibited agonistic activity and low off-target binding, was converted to the bispecific format described in paper I, but with a humanised version of the single chain fragment variable (scFv). This candidate drug, in combination with peptide cargo, generated potent anti-tumour effects in several tumour models and demonstrated low toxicity and immunogenicity. 

    In paper IV, the peptide tag binding to the bispecific antibody was modified by amino acid substitution to assess whether affinity binding and/or biological effects could be modified. The substitution with a non-conserved amino acid led to a slightly decreased affinity binding. This substitution led to modified in vitro antigen processing and/or presentation of the CD4+ and CD8+ T cell antigens, while in vivo activity appeared to depend more on conjugate stability.

    In conclusion, this bispecific antibody platform facilitates flexible peptide cargo loading by affinity binding and provides a promising opportunity for personalised therapy by using patient-specific neoantigen peptides as cargo to generate effective anti-tumour T cell responses.

    Abstract [en]

    The agonistic potentials of therapeutic anti-CD40 antibodies have been profiled in relation to antibody isotype and epitope specificity. Still, clinical impact relies on a well-balanced clinical efficacy versus target-mediated toxicity. As CD40-mediated immune activation must rely on a combination of stimulation of antigen-presenting cells (APCs) alongside antigen presentation, for efficient T cell priming, alternative approaches to improve the therapeutic outcome of CD40-targeting strategies should focus on providing optimal antigen presentation together with CD40 stimulation. Herein, a bispecific antibody targeting CD40 as a means to deliver cargo (i.e., synthetic peptides) into APCs through a non-covalent, high-affinity interaction between the antibody and the cargo peptide, further referred to as the Adaptable Drug Affinity Conjugate (ADAC) technology, has been developed. The ADAC platform demonstrated a target-specific CD4(+) and CD8(+) T cell expansion in vitro and significantly improved peptide-specific CD8(+) T cell proliferation in vivo. In addition, the strategy dramatically improved the in vitro and in vivo half-life of the synthetic peptides. Future applications of ADAC involve pandemic preparedness to viral genetic drift as well as neoepitope vaccination strategies where the bispecific antibody is an off-the-shelf product, and the peptide antigen is synthesized based on next-generation sequencing data mining.

    Abstract [en]

    The transition from preclinical biological drug development into clinical trials requires an efficient upscaling process. In this context, bispecific antibody drugs are particularly challenging due to their propensity to form aggregates and generally produce low titers. Here, the upscaling process for a tetravalent bispecific antibody expressed by a piggyBac transposon-mediated stable HEK293 cell pool has been evaluated. The project was performed as a case study at Testa Center, a non-GMP facility for scale-up testing of biologics in Sweden, and encompassed media adaptation strategies, fed-batch optimization and a novel antibody purification technology. The cell pool was adapted to different culture media for evaluation in terms of cell viability and titers compared to its original Expi293 Expression Medium. These parameters were assessed in both sequential stepwise adaption and direct media exchanges. By this, a more affordable medium was identified that did not require stepwise adaptation and with similar titers and viability as in the Expi293 Expression Medium. Fed-batch optimizations resulted in culture densities reaching up to 20 x 106 viable cells/mL with over 90 % viability 12 days postinoculum, and antibody titers three times higher than corresponding batch cultures. By implementing a novel high-speed protein A fiber technology (Fibro PrismA) with a capture residence time of only 7.5 s, 8 L of supernatant could be purified in 4.5 h without compromising the purity, structural integrity and function of the bispecific antibody. Results from this study related to medium adaptation and design of fed-batch protocols will be highly beneficial during the forthcoming scale-up of this therapeutic antibody.

    Abstract [en]

    Current antibody-based immunotherapy depends on tumor antigen shedding for proper T cell priming. Here we select a novel human CD40 agonistic drug candidate and generate a bispecific antibody, herein named BiA9*2_HF, that allows for rapid antibody-peptide conjugate formation. The format is designed to facilitate peptide antigen delivery to CD40 expressing cells combined with simultaneous CD40 agonistic activity. In vivo, the selected bispecific antibody BiA9*2_HF loaded with peptide cargos induces improved antigen-specific proliferation of CD8+ (10-15 fold) and CD4+ T cells (2-7 fold) over control in draining lymph nodes. In both virus-induced and neoantigen-based mouse tumor models, BiA9*2_HF demonstrates therapeutic efficacy and elevated safety profile, with complete tumor clearance, as well as measured abscopal impact on tumor growth. The BiA9*2_HF drug candidate can thus be utilized to tailor immunotherapeutics for cancer patients.

    Mitigating Urban Microplastic Pollution: Investigating Nature-Based Filters in Stormwater Management2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Microplastic (MP) pollution has emerged as a global environmental concern, particularly in urban environments, where stormwater serves as a major transport pathway for MPs into aquatic ecosystems. This thesis investigates MP sources, distribution, and removal strategies in urban settings, with a focus on stormwater filtration solutions. Field studies were conducted in Uppsala, Sweden, to assess MP contamination in road dust and spider webs (Paper I). Results indicated spatial variability, with indoor parking lots exhibiting the highest MP loads, predominantly polyurethane. Spider webs effectively captured airborne MPs, and particularly polyester fibers, demonstrating their potential as passive samplers of atmospheric pollution. To mitigate MP transport via stormwater, laboratory and pilot-scale filtration experiments were conducted using sand, bark, and biochar as filter materials (Papers II-IV). Laboratory-scale horizontal flow filters demonstrated high MP retention across all tested materials. However, results indicated that the retention efficiency was influenced by MP shape and size, with fibers being particularly well retained. Additionally, biochar-beds suggested a polarity-dependent filtration effect, preferentially removing non-polar MPs over polar MPs, emphasizing the role of polymer properties in filtration performance (Paper IV). The pilot-scale biochar-beds were tested with semi-artificial stormwater and with simulated environmental stressors, including prolonged drying and road salt exposure (Paper IV). Results revealed that biochar efficiently removed MPs and particulate-bound metals. Environmental factors influenced filter performance; drying-induced structural changes in biochar resulted in an initial surge of MP release upon rewetting, and pH shifts altered metal speciation and reduced metal removal efficiency. This research advances the understanding of urban MP pollution and its remediation, demonstrating that filtration-based stormwater treatments can effectively capture MPs before they reach aquatic ecosystems. The findings emphasize the need for environmentally robust stormwater management solutions and highlight the importance of considering real-world stressors in filtration system design. Future studies should explore long-term filter performance and the combined effects of multiple environmental stressors to optimize MP removal strategies.

    Abstract [en]

    Microplastics accumulate in stormwater and can ultimately enter freshwater recipients, and pose a serious risk to aquatic life. This study investigated the effectiveness of lab-scale horizontal flow sand filters of differing lengths (25, 50 and 100 cm) in retaining four types of thermoplastic microplastics commonly occurring in stormwater runoff (polyamide, polyethylene, polypropylene, and polyethylene terephthalate). Despite the differences in particle shape, size and density, the study revealed that more than 98% of the spiked microplastics were retained in all filters, with a slightly increased removal with increased filter length. At a flow rate of 1 mL/min and after one week of operation, 62–84% of the added microplastics agglomerated in the first 2 cm of the filters. The agglomerated microplastics included 96% of high-density fibers. Larger-sized particles were retained in the sand media, while microplastics smaller than 50 μm were more often detected in the effluent. Microplastics were quantified and identified using imaging based micro Fourier Transform Infrared Spectroscopy. The efficient retention of microplastics in low-flow horizontal sand filters, demonstrated by the results, highlights their potential importance for stormwater management. This retention is facilitated by various factors, including microplastic agglomeration, particle sedimentation of heavy fibers and favorable particle-to-media size ratios.

    Abstract [en]

    Organic materials such as bark and biochar can be effective filter materials to treat stormwater. However, the efficiency of such filters in retaining microplastics (MPs) - an emerging stormwater pollutant - has not been sufficiently studied. This study investigated the removal and transport of a mixture of MPs commonly associated with stormwater. Different MP types (polyamide, polyethylene, polypropylene, and polystyrene) were mixed into the initial 2 cm material of horizontal bark and biochar filters of 25, 50, and 100 cm lengths. The MP types consisted of spherical and fragmented shapes in size ranges of 25-900 μm. The filters were subjected to a water flow of 5 mL/min for one week, and the total effluents were analyzed for MPs by μFTIR imaging. To gain a deeper insight, one 100 cm bark filter replica was split into 10 cm segments, and MPs in each segment were extracted and counted. The results showed that MPs were retained effectively, >97%, in all biochar and bark filters. However, MPs were detected in all effluents regardless of filter length. Effluent concentrations of 5-750 MP/L and 35-355 MP/L were measured in bark and biochar effluents, respectively, with >91% of the MP counts consisting of small-sized (25 μm) polyamide spherical particles. Combining all data, a decrease in average MP concentration was noticed with longer filters, likely attributed to channeling in a 25 and 50-cm filter. The analyses of MPs in the bark media revealed that most MPs were retained in the 0-10 cm segment but that some MPs were transported further, with 19% of polyamide retained in the 80-90 cm segment. Overall, this study shows promising results for bark and biochar filters to retain MPs, while highlighting the importance of systematic packing of filters to reduce MP emissions to the environment from polluted stormwater.

    Abstract [en]

    Introduction:Electroconvulsive therapy (ECT) is a treatment method for, among otherthings, severe depression and other psychiatric conditions. The treatment involves a short,induced seizure under anesthesia. ECT gives good results in many people, but there is a highrisk of suffering from memory problems and other cognitive problems.

    Aim: The aim of the study was to investigate the experiences of ECT treatment in patientssuffering from mental illness.

    Method: A qualitative literature study in which ten scientific articles with a qualitativeapproach were analyzed. The databases used in the literature search were PubMed, CINAHL,and PsycInfo.

    Result: The result of the study shows that ECT for the most part has a good and fast effect -even though a lot of patients get side effects like memory loss. These effects did affect thepatients negatively and lowered their quality of life. Patients felt like they got too littleinformation about the treatment and that they didn't feel involved in their treatment plan.Family and friends who were supportive contributed to a better experience for the patients.

    Conclusion: The literature review shows that many people experienced ECT treatment aspositive. Negative experiences involved memory difficulties, insufficient information andlack of participation in the treatment planning process. To improve the experience, thehealthcare provider should provide the patient with information about their treatment andmake them participate in their care.

    ABSTRACT

    Introduction: The waiting time for a heart and/or lung transplant is long, due to both the increasing demand and the shortage of organs. As a result, many patients die before they receive a transplant. The uncertainty regarding the timing of the procedure can cause psychological distress for both patients and their relatives. While some research has addressed the physical and psychological effects of the waiting period for transplant patients, there is still a lack of a deeper understanding of their emotional and psychological experiences during this time. Therefore, it is important to understand how these patients experience the waiting time on a deeper level to enable better nursing care for the patients.

    Aim: To describe experiences of patients during the waiting time for heart and/or lung transplant.

    Methods: A general literature review with a descriptive design and qualitative approach. Ten scientific articles were retrieved from the PubMed and CINAHL databases.

    Results: Two categories and six subcategories were identified. The findings revealed that patients waiting for heart and/or lung transplants experienced both positive and negative emotions. Support and information from other transplant patients and healthcare professionals had a positive impact on their experiences during the waiting period. The transplant was seen as a chance for survival but also evoked feelings of guilt and gratitude. The waiting time was perceived as long, causing feelings of anxiety and fear.

    Conclusion: The waiting time for heart and lung transplantation was characterized by both positive and negative emotions. Patients' experiences during the waiting period were positively influenced by support and information from both other transplant patients and healthcare professionals. Despite this, there are other areas of care that could be improved, such as information, psychosocial support and individualized care. Further research into how patients manage their emotions and thoughts and what support they need to be able to manage these emotions and thoughts during the waiting period could enable improved patient care.

    Design and additive manufacturing of soft-magnetic materials and metallic glasses2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Fe-based metallic glasses as soft-magnetic cores in energy applications increase the efficiency and significantly lower the energy losses during use, compared to conventional electrical steels. Metallic glass production calls for rapid cooling from high temperatures, solidifying the liquid before it crystallises. The additive manufacturing technique laser-based powder bed fusion is an increasingly popular production method for these materials. The material is melted stepwise, in small melt pool volumes at a time, allowing the heat to dissipate fast. The extreme thermal environment in laser-based powder bed fusion additive manufacturing enables the production of metallic glasses without shape restrictions. However, thermal cycling can also lead to residual stress and it is challenging to find a stable process window where defects like cracks, pores, or lack-of-fusion are not deteriorating the material properties. A great challenge is also to control the devitrification, nucleation and growth of crystalline phases commonly occurs, especially in the heat affected zone around the melt pool.

    This work explores production and devitrification of metallic glasses in extreme thermal environments, with the intention to evaluate composition and production methods for soft-magnetic materials and metallic glasses. The influence of boron concentration and heating rate on Fe-Co-Nb-B metallic glasses is captured with millisecond precision using high brilliance synchrotron diffraction techniques. We are able to show the shift in the initial phase formation from α-Fe to the metastable Fe23B6 for higher boron concentrations (20 at.%) and high heating rates. The devitrification at slow heating rates was also investigated, using both calorimetry and magnetometry. The experimental description of the devitrification was additionally complemented with modelling. Using the same in-situ setup, we also evaluated the impact of oxygen contamination in a Zr-based metallic glass. Two different devitrifi-cation modes, homogeneous and heterogeneous, are measured and successfully mod-elled, for a selection of oxygen doping levels. Additionally, two studies are presented where Fe-based metallic glass and metallic glass composites are manufactured using laser-based powder bed fusion. The process development was successfully supported by Kerr microscopy imaging of melt pools of single tracks and the magnetic and structural properties of the produced parts were evaluated.

    Abstract [en]

    Fe-based metallic glass composites, consisting of dispersed nanocrystallites within an amorphous metallic glass matrix, are used as low-loss soft-magnetic components in energy conversion devices. The nanocrystallites are formed by partial devitrification of the amorphous alloy and the properties of the composite depend on the alloy composition and the devitrification process. Understanding the rate-dependent crystallisation kinetics is therefore essential for tailoring the properties of metallic glass composites. In this study, we monitor the devitrification process in situ during rapid heating of metallic glasses with composition (Fe0.75Co0.25)95−xNb5Bx, x = 15 − 20 at.%, by using high-energy wide angle X-ray scattering. The results are compared to samples devitrified at low heating rates, analysed using differential scanning calorimetry, X-ray diffraction, and magnetometry. Additionally, we present a model describing the crystallisation kinetics based on classical nucleation and growth theory coupled to thermodynamic data for a generalised Fe-B system. The model successfully captures the onset of devitrification as a function of time, temperature, and B-concentration, providing valuable insights for the design of Fe-based soft-magnetic materials.

    Abstract [en]

    Metallic glasses exhibit unique mechanical properties. For metallic glass composites (MGC), composed of dispersed nanocrystalline phases in an amorphous matrix, these properties can be enhanced or deteriorated depending on the volume fraction and size distribution of the crystalline phases. Understanding the evolution of crystalline phases during devitrification of bulk metallic glasses upon heating is key to realizing the production of these composites. Here, results are presented from a combination of in situ small- and wide-angle X-ray scattering (SAXS and WAXS) measurements during heating of Zr-based metallic glass samples at rates ranging from 102 to 104 Ks−1 with a time resolution of 4ms. By combining a detailed analysis of scattering experiments with numerical simulations, for the first time, it is shown how the amount of oxygen impurities in the samples influences the early stages of devitrification and changes the dominant nucleation mechanism from homogeneous to heterogeneous. During melting, the oxygen rich phase becomes the dominant crystalline phase whereas the main phases dissolve. The approach used in this study is well suited for investigation of rapid phase evolution during devitrification, which is important for the development of MGC.

    Abstract [en]

    Additive manufacturing makes the production of bulk metallic glasses possible in thicknesses exceeding the critical casting thickness. However, a crucial challenge is the build-up of thermally induced stress, often resulting in printed parts suffering from cracking. In this study, the process parameters are optimised for printing soft-magnetic metallic glass samples of an Fe-based alloy (Fe73.8P10.6Mo4.2B2.3Si2.3C6.7), using laser beam powder bed fusion. In addition, the structural and magnetic properties of as-received and heat-treated powder are investigated and compared to those of the printed samples. Kerr microscopy is used for imaging the magnetic domains on single track cross-sections produced on top of a polished printed sample. This reveals the shape of the melt pool of a single laser track, as well as the magnetic domains around it and in other regions of the printed sample. The shape and size of the magnetic domains reflect the residual stress in the sample through the effect of magneto-elastic coupling. This magnetic contrast could be used to get further insights into how to control the development of stress during the printing process.

    Abstract [en]

    Additive manufacturing of Fe-based metallic glass alloys can be used to fabricate customised soft-magnetic components with an unprecedented geometrical freedom. In this work, we present an efficient parameter development process for PBF-LB processing of the Fe-based metallic glass alloy Kuamet 6B2. The development is focused on combining che-querboard and double exposure printing to achieve high relative density, high amorphous content, low coercivity, and low enough residual stress so that large parts can be manufactured. As single track study was used to increase the efficiency of the process development; images of single track melt pools produced using different process parameters were used to make informed decisions about which parameters to proceed with for the second exposure. The produced samples were investigated using XRD, magnetometry, magneto-optical imaging, and EBSD. The developed parameters were used to produce large ring-shaped cores with radii of 5 cm, used for measuring the relative permeability.

    The North-Eastern Neo-Aramaic Dialect of Tin2025In: Interconnected Traditions: Semitic Languages, Literatures, and Cultures — A Festschrift for Geoffrey Khan: Volume 2: The Medieval World, Judaeo-Arabic, and Neo-Aramaic / [ed] Aaron D.

    Abstract [en]

    The article presents the Neo-Aramaic dialect of Tin, a village in the Ṣapna valley in northern Iraq, focusing on the dialect’s phonology, morphology, and lexicon. This variety, spoken by Christians of the Chaldean Catholic Church, is most closely related to the nearby Christian dialect of Aradhin, but is nevertheless distinct in many ways. The synchronic description is supplemented with a comparative and historical perspective, indicating how Tin’s features fit into the NENA dialectal map and how unusual or unexpected forms can be explained by historical developments. Contact influences from Northern Kurdish and vernacular Arabic are also discussed. Interesting features of this dialect include the innovation of an initial /d/ in the Present Base forms of verba primae /ʾ/ and sporadic cases of vowel harmony.

    The Origin and Diversification of Ectomycorrhizal Fungi2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Ectomycorrhiza (ECM) is a symbiotic relationship between fungi and plants, which is essential for many woody plants. ECM fungi have evolved independently multiple times in several lineages from saprotrophic ancestors. However, the origin and diversification processes of ECM lineages are still not well understood. In Paper I, we addressed whether ECM lineages evolved independently or if reversals to saprotrophy occurred. These hypotheses were tested using model-based methods and a phylogeny based on 2 174 ECM taxa. We concluded that our inferences about ECM evolution are affected by whether a rate shift in different time periods or ECM clades is allowed, and that reversals to saprotrophy are probably rare. In Paper II, I investigated whether the ECM-linked genomic changes occurred abruptly at the transition to the ECM lifestyle or were part of a trend before or after the transition in ECM lineages. I compared 26 genomes from ECM species in Inocybaceae with six saprotrophic outgroups. The findings suggest that the molecular changes, important for transition to the ECM lifestyle, occur in proximity to the origin of this lifestyle in Inocybaceae. In Paper III, I explored whether genomic diversity in ECM lineages is shaped by independent transitions or due to diversification within each lineage. I compiled a phylogenetically diverse dataset of 75 genomes, representing eight ECM lineages. The findings show that while genomic diversity from lineage-level additions quickly saturates for all enzyme groups investigated, species-level additions continue to contribute new diversity beyond the limits of our dataset. In Paper IV, we tested the mutual exclusivity of psilocybin and muscarine in Inocybaceae species by screening 21 samples. I also explored the origin and evolution of genes involved in psilocybin production in these species using 24 genomes. We detected both psilocybin and muscarine, for the first time, in a single species of Inocybaceae and also concluded that the psilocybin gene cluster has evolved through convergent evolution, with two possible origins of the gene cluster within the family. Overall, this thesis contributes to improving our understanding of ECM fungal evolution and highlights how traits that appear alike can emerge through distinct evolutionary processes.

    Abstract [en]

    Ectomycorrhiza (ECM) is a symbiotic relation between plant and fungi that is essential for nutrient uptake of many stand forming trees. There are two conflicting views about the evolution of ECM in fungi suggesting (1) relatively few transitions to ECM followed by reversals to non-ECM, or (2) many independent origins of ECM and no reversals. In this study, we compare these, and other, hypotheses and test the impact of different models on inference. We assembled a dataset of five marker gene sequences (nuc58, nucLSU, nucSSU, rpb1, and rpb2) and 2,174 fungal taxa covering the three subphyla: Agaricomycotina, Mucoromycotina and Pezizomycotina. The fit of different models, including models with variable rates in clades or through time, to the pattern of ECM fungal taxa was tested in a Bayesian framework, and using AIC and simulations. We find that models implementing variable rates are a better fit than models without rate shift, and that the conclusion about the relative rate between ECM and non-ECM depend largely on whether rate shifts are allowed or not. We conclude that standard constant-rate ancestral state reconstruction models are not adequate for the analysis of the evolution of ECM fungi, and may give contradictory results to more extensive analyses.

    Abstract [en]

    The genomes of ectomycorrhizal (ECM) fungi have a reduced number of genes encoding Carbohydrate-Active EnZymes (CAZymes), expansions in transposable elements (TEs) and small secreted proteins (SSPs) compared with saprotrophs. Fewer genes for specific peptidases and lipases in ECM fungi are also reported. It is unclear whether these changes occur at the shift to the ECM habit or are more gradual throughout the evolution of ECM lineages.

    We generated a genomic dataset of 20 species in the ECM lineage Inocybaceae and compared them with six saprotrophic species.

    Inocybaceae genomes have fewer CAZymes, peptidases, lipases, secondary metabolite clusters and SSPs and higher TE content than their saprotrophic relatives. There was an increase in the rate of gene family evolution along the branch with the transition to the ECM lifestyle. This branch had very high rate of evolution in CAZymes and had the largest number of contractions. Other significant changes along this branch included expansions in transporters, transposons-related genes and communication genes such as fungal kinases.

    There is a high concentration of changes in proximity to the transition to the ECM lifestyle, which correspond to the identified key changes for the gain of this lifestyle.

    Module categories in the absence of adjunctions2025Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis consists of an introduction and three research articles in the field of module categories. In Paper I, we we establish a biequivalence between the bicategory of cyclic module categories, Tambara modules and their morphisms for a fixed monoidal category, and the bicategory of monoids, bimodules and bimodule morphisms in the category of Tambara modules on the same monoidal category. This yields additional functoriality properties to the reconstruction theory of module categories for tensor categories, and gives a weak generalization thereof to the setting of general, in particular non-rigid, monoidal categories. Further, we prove an action-via-enrichment result for Tambara modules, extending the results of Wood into the non-closed setting.

    In Paper II, we define a notion of dual objects in semigroup categories. We show that if a semigroup category is rigid, then this semigroup category is promonoidal. We also solve a problem of lifting module categories for semigroup categories, and characterize finite tensor categories in terms of their semigroup categories of projective objects.

    In Paper III, we develop a reconstruction theory for abelian module categories over abelian monoidal categories which is very close to the tensor-categorical theory. Rather than (co)monoids in the base monoidal category , we obtain lax module (co)monads on it, generalizing (co)monoids, and we give counter-examples to the existence of a reconstructing monoid. For the monoidal category of comodules over a bialgebra, we show that such comonads are given by Hopf trimodule algebras. This gives categorical proofs of the theorem of Hopf trimodules of Hausser and Nill and the Hopf-monadic theorem of Hopf modules of Bruguières, Lack and Virelizier. Towards these results, we show an Eilenberg-Watts theorem for lax module monads, and extend the formalism of multicategories of Linton coequalizers of Aguiar, Haim and López Franco to the multiactegorical setting.

    Abstract [en]

    We use the theory of Tambara modules to extend and generalize the reconstruction theorem for module categories over a rigid monoidal category to the nonrigid case. We show a biequivalence between the 2-category of cyclic module categories over a monoidal category C and the bicategory of algebra and bimodule objects in the category of Tambara modules on C. Using it, we prove that a cyclic module category can be reconstructed as the category of certain free module objects in the category of Tambara modules on C, and give a sufficient condition for its reconstructability as module objects in C. To that end, we extend the definition of the Cayley functor to the nonclosed case, and show that Tambara modules give a proarrow equipment for C-module categories, in which C-module functors are characterized as 1-morphisms admitting a right adjoint. Finally, we show that the 2-category of all C-module categories embeds into the 2-category of categories enriched in Tambara modules on C, giving an “action via enrichment” result.

    Abstract [en]

    We develop a theory of adjunctions in semigroup categories, that is, monoidal categories without a unit object. We show that a rigid semigroup category is promonoidal, and thus one can naturally adjoin a unit object to it. This extends the previous results of Houston in the symmetric case, and addresses a question of his. It also extends the results in the non-symmetric case with additional finiteness assumptions, obtained by Benson-Etingof-Ostrik, Coulembier, and Ko-Mazorchuk-Zhang. We give an interpretation of these results using comonad cohomology, and, in the absence of finiteness conditions, using enriched traces of monoidal categories. As an application of our results, we give a characterization of finite tensor categories in terms of the finitary 2-representation theory of Mazorchuk–Miemietz.

    (English)Manuscript (preprint) (Other academic)
    Abstract [en]

    By building on the notions of internal projective and injective objects in a module category introduced by Douglas, Schommer-Pries, and Snyder, we extend the reconstruction theory for module categories of Etingof and Ostrik. More explicitly, instead of algebra objects in finite tensor categories, we consider quasi-finite coalgebra objects in locally finite tensor categories. Moreover, we show that module categories over non-rigid monoidal categories can be reconstructed via lax module monads, which generalize algebra objects. For the monoidal category of finite-dimensional comodules over a (non-Hopf) bialgebra, we give this result a more concrete form, realizing module categories as categories of contramodules over Hopf trimodule algebras -- this specializes to our tensor-categorical results in the Hopf case. In this context, we also give a precise Morita theorem, as well as an analogue of the Eilenberg--Watts theorem for lax module monads and, as a consequence, for Hopf trimodule algebras. Using lax module functors we give a categorical proof of the variant of the fundamental theorem of Hopf modules which applies to Hopf trimodules. We also give a characterization of fusion operators for a Hopf monad as coherence cells for a module functor structure, using which we similarly reinterpret and reprove the Hopf-monadic fundamental theorem of Hopf modules due to Bruguières, Lack, and Virelizier.

    Barndom i förändring: En diskursanalys av hur sociala normer, makt och auktoritet förhandlas i Alfons Åberg-böcker2025Independent thesis Basic level (university diploma), 210 HE creditsStudent thesis
    Abstract [sv]

     Syftet med denna studie är att undersöka hur normer och maktstrukturer gestaltas i Alfons Åberg-böckerna med utgångspunkt i lärande och kulturella värderingar kring makt och auktoritet i barns sociala relationer. Studien avser även att analysera hur litterära gestaltningar kan påverka barns förståelse av barn-vuxenrelationer samt vilken betydelse de kan ha för böckernas långvariga popularitet. För att besvara forskningsfrågorna genomfördes en systematisk analys av ett urval av Alfons Åberg-böckerna. Analysen utgår ifrån textstudier med utgångspunkt i litteraturvetenskapliga begrepp, diskursanalys och socialkonstruktivistiska teorier.  Studien bygger på tidigare forskning om barnlitteratur och maktstrukturer och belyser hur text konstruerar normer och auktoritet relationer. I analysen synliggörs de språkliga som används för att förmedla sociala och kulturella värderingar.

    Resultaten från den första delstudien indikerar att Alfons Åberg-böckerna återger traditionella maktstrukturer genom att skildra hierarkiska relationer, där vuxna i regel tillskrivs auktoritet. Samtidigt framkommer att böckerna även inkluderar situationer där barn ges handlingsutrymme och möjlighet att påverka sin sociala omgivning. Den andra delstudien visar att barns förståelse av relationer präglas av en tydlig medvetenhet om de faktorer som påverkar uppfattningen om vuxna samt deras egen position i dessa relationer. Ur ett socialkonstruktivistiskt perspektiv blir det tydligt hur litteraturen både speglar och omförhandlar normer och maktförhållanden genom interaktionen mellan barn och vuxna. Böckernas popularitet kan delvis förstås genom deras relaterbara skildringar av barn-vuxenrelationer samt pedagogiska relevans.

    Rättvist är inte samma sak som lika: -En kombinerad metodstudie om pedagogers arbete med barn i behov av särskilt stöd2025Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie är att undersöka uppfattningar om hur pedagoger i förskola och förskoleklass arbetar för att inkludera samt bemöta barns olika behov i barngruppen, detta med särskilt fokus på barn i behov av särskilt stöd. Detta är en kombinerad metodstudie där en kvalitativ intervjustudie och en kvantitativ enkätstudie genomförts. Det teoretiska ramverket utgår från Claes Nilholms tre specialpedagogiska perspektiv: det kompensatoriska, det kritiska och dilemmaperspektivet.  Resultatet visar att pedagoger uppfattar inkludering som en självklar del av sitt uppdrag där barns olikheter ses som utgångspunkt för det pedagogiska arbetet. Relationer, flexibilitet och tidiga insatser lyfts fram som centrala delar i det inkluderande arbetet medan brist på resurser, tid och kompetens utgör betydande utmaningar. Analysen visar att pedagoger ofta navigerar mellan ideal om inkludering och praktiska begränsningar, något som tydligt speglas i dilemmaperspektivet. Studien belyser vikten av att inkludering inte endast handlar om fysisk närvaro, utan om aktivt deltagande och en tillgänglig lärmiljö. Resultaten kan bidra med förståelse för hur lärare uppfattar inkluderingsarbetet i praktiken, samt vilka villkor som påverkar möjligheterna att nå en likvärdig utbildning för alla barn.

    Abstract [en]

    The entry introduces Kosovo heritage politics and focuses on the consequences and the aftermath of the Kosovo War in 1999. The war led to the creation of a sovereign Kosovar nation-state, in which heritage has been used both to construct a new national identity but also to maintain the conflict between Kosovo and Serbia. A historical overview of the development of heritage legislation in Kosovo leading up to the war is given, as well as an account of the post-war development. The case of Mitrovica is presented in more detail. A divided town in northern Kosovo in which heritage from different historical periods is found, episodes in Mitrovica’s past are actively used and claimed by both Kosovo-Albanians and Serbs. Urban spaces such as squares, bridges, buildings and monuments are used to support these claims, celebrating past conflicts, and resisting attempts of reconciliation and urban reconstruction. By looking at choices and uses of heritage assets, how historical circumstances influence the possibilities of identifying a heritage shared by several ethnic communities is presented.

    Autogene cevumeran with or without atezolizumab in advanced solid tumors: a phase 1 trial2025In: Nature Medicine, ISSN 1078-8956, E-ISSN 1546-170X, Vol. 31, no 1, p. 152-164Article in journal (Refereed)
    Abstract [en]

    Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors. The primary objective was safety and tolerability; exploratory objectives included evaluation of pharmacokinetics, pharmacodynamics, preliminary antitumor activity and immunogenicity. Non-prespecified interim analysis showed that autogene cevumeran was well tolerated and elicited poly-epitopic neoantigen-specific responses, encompassing CD4+ and/or CD8+ T cells, in 71% of patients, most of them undetectable at baseline. Responses were detectable up to 23 months after treatment initiation. CD8+ T cells specific for several neoantigens constituted a median of 7.3% of circulating CD8+ T cells, reaching up to 23% in some patients. Autogene cevumeran-induced T cells were found within tumor lesions constituting up to 7.2% of tumor-infiltrating T cells. Clinical activity was observed, including one objective response in monotherapy dose escalation and in two patients with disease characteristics unfavorable for response to immunotherapy treated in combination with atezolizumab. These findings support the continued development of autogene cevumeran in earlier treatment lines. ClinicalTrials.gov registration: NCT03289962.

    Measurement of CP Violation Observables in D+K- K+ π+ Decays2024In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 133, no 25, article id 251801Article in journal (Refereed)
    Abstract [en]

    A search for violation of the charge-parity (CP) symmetry in the D+ -> K- K+ pi(+) decay is presented, with proton-proton collision data corresponding to an integrated luminosity of 5.4 fb(-1), collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the D+ and D- phase-space distributions, with instrumental asymmetries subtracted using the D-s(+) -> K- K+ pi(+) decay as a control channel. The p value for the hypothesis of CP conservation is 8.1%. The CP asymmetry observables A(CP vertical bar S)(phi pi+) = (0.95 +/- 0.43(stat) +/- 0.26(syst)) x 10(-3) and A(CP vertical bar S)((K) over bar *0 K+) = (-0.26 +/- 0.56(stat) +/- 0.18(syst)) x 10(-3) are also measured. These results show no evidence of CP violation and represent the most sensitive search performed through the phase space of a multibody decay.

    Measurement of D0 - (D)over-bar0 mixing and search for CP violation with D0 →K+ π- decays2025In: Physical Review D: covering particles, fields, gravitation, and cosmology, ISSN 2470-0010, E-ISSN 2470-0029, Vol. 111, no 1, article id 012001Article in journal (Refereed)
    Abstract [en]

    A measurement of the time-dependent ratio of the D-0 -> K+ to (D) over bar (0) pi(-) decay rates is reported. The analysis uses a sample of proton-proton collisions corresponding to an integrated luminosity of 6 fb- 1 recorded by the LHCb experiment from 2015 through 2018 at a center-of-mass energy of 13 TeV. The D-0 meson is required to originate from a D*(2010)(+) -> D-0 pi(+) decay, such that its flavor at production is inferred from the charge of the accompanying pion. The measurement is performed simultaneously for the K+ pi(-) and K- pi(+) final states, allowing both mixing and CP-violation parameters to be determined. The value of the ratio of the decay rates at production is determined to be R-K pi = (343.1 +/- 2.0) x 10(-5). The mixing parameters are measured to be c(K pi) = (51.4 +/- 3.5) x 10(-4) and c(K pi)(0) = (13 +/- 4) x 10(-6), where root R(K pi)c(K pi) is the linear coefficient of the expansion of the ratio as a function of decay time in units of the D-0 lifetime, and c(K pi)(0) is the quadratic coefficient, both averaged between the K+ pi(-) and K- pi(+) final states. The precision is improved relative to the previous best measurement by approximately 60%. No evidence for CP violation is found.

    Anarchy in the Game of Thrones2020In: Neohelicon, ISSN 0324-4652, E-ISSN 1588-2810, Vol. 47, no 1, p. 117-129Article in journal (Refereed)
    Abstract [en]

    Recent scholarship has come to rethink how the concept of anarchy captures the fragmented plurality of contemporary world politics. This article continues that inquiry through an interpretative reading of the popular TV-series Game of Thrones. The appeal of this show partly derives from its animation of medieval tropes to interpellate with contemporary global politics; it echoes power struggles constitutive of today’s international relations. However, while the fantasy show portrays conflictual relations between different claimants of the Iron Throne in Westeros, it also composes subaltern voices amidst these violent claims to power. This article concludes that such an interpretation diversifies the meanings of anarchy, as both violence and freedom, in the ‘game of thrones’ of contemporary politics.

    Contextualizing negative attitudes to wildlife and wildlife governance in the moral economy of Swedish farmers2022In: Frontiers in Conservation Science, E-ISSN 2673-611X, Vol. 3, article id 1014769Article in journal (Refereed)
    Abstract [en]

    Conflicts over managing large carnivores have been prominent in Sweden in recent decades. The most significant controversies are related to wolves, but the bear, lynx, and wolverine are also included. While the state and environmental organizations make efforts to guarantee a viable population of the large protected carnivores, farmers generally have a negative attitude towards large carnivores and a low level of trust in wildlife governance. Based on 22 in-depth interviews, 37 telephone questionnaires with Swedish farmers, and an analysis of 111 applications for protective hunting, this paper aims to demonstrate how these farmers' perspectives on large carnivores can be explained by moral (sense of right and wrong) and moral economy (a system of obligations related to values and relations intervening with political views and financial decisions). The paper argues that farming, in addition to being an economic activity, is integrated with values, heritage, and relations to other human beings and animals. Farmers understand these values to be threatened by large carnivores, especially by wolves. The paper contextualizes negative sentiments, conflicts, protests, and also illegal hunting of large carnivores in relation to a sense of morals, sense of fairness, meanings, traditions, and mechanisms of daily life. We argue that this perspective provides a lens through which to interpret the conflict between farmers on the one side and the state and animal rights activists on the other. Such interpretation has consequences for understanding the legitimacy of government, shifting the focus from the processes of political governance (predominant in liberal political philosophy) to legitimacy tied to collective notions of social goods.

    “Can a Christian also be a 100 per cent National Socialist?”: The Holocaust, the Wehrmacht and Religious Faith2025In: Journal of Genocide Research, ISSN 1462-3528, E-ISSN 1469-9494Article in journal (Refereed)
    Abstract [en]

    Hitler’s invasion of Poland and subsequent invasion of the Soviet Union initiated a war centred around race and the expansion of the German Nazi empire. Millions of German soldiers between the ages of eighteen to forty-five from all parts of society participated in what was represented as a war in the defence of the German Volksgemeinschaft. In reality it was a war of annihilation targeted against Jews and Bolsheviks. While the Wehrmacht officially was meant to wage war, not annihilate Jews, many of its members participated actively or passively by aiding the killers, or by witnessing the genocidal killings. A majority of these men were devout Christians, and they were all devoted to a solution to the so-called “Jewish problem.” This article explores the individual faith of Christian Wehrmacht soldiers in the context of the war of annihilation and genocidal violence on the Eastern Front during the Second World War, including the negotiations and re-negotiations of their faith in relation to the killing of Jews, communists, and other “undesirables” in Eastern Europe. It analyses the perspective of soldiers on the ground in Poland and Eastern Europe through their own words, as presented in the private correspondence of sixty-seven Wehrmacht soldiers, and will argue that the perceived threat of Jews and communism to Christianity, enabled the soldiers to re-interpret their faith to exclude Jews and communists from any rules of Christian morality. This dynamic will also be explored in relation to how these men encountered Christians in communist Eastern Europe; on being confronted with fellow Christians who had been deprived of their right to practice their faith, the soldiers found kindship as well as new meaning and a higher purpose to the annihilation of Jews and the war of extermination in the East.

    Det humanistiska bibelverket: Kring den nordiska reformationens bibelöversättning2024Book (Refereed)
    Abstract [en]

    The study is a piece of philology, combined with historical translation studies. It is intended to update, further develop and partly revalue the conception of the Swedish and Danish Reformers’ translation of the Holy Bible into the contemporary vernaculars, carried out in the second quarter of the 16th century.

    A new angle of approach is the view of the early Reformation Bible in Scandinavia as a coherent complex of text, along with the attempt to sharply distinguish between the process of translation, i.e., the actual linguistic shift, and the subsequent revision of the text before printing. To that end, the term and the notion of translation philology has been coined. A third new feature in this biblical approach in Scandinavian philology is the focusing on the grammatical (syntactical) structure of phrases and sentences, not so much on the lexicon and vocabulary.

    After an introductory chapter (1), the content of the book falls into two main parts. In the first (chapters 2–5), the focus is on “the documents and history”, in the second (chapters 6–15) on “the documents and language”.

    Though treating the entire East Scandinavian Bible translation in the formative early Reformation epoch on the same methodologial terms, the author pays particular attention to the Swedish New testament 1526. The complicated preparation of this pioneering work is analysed and described with a method – and partly even a result – sharply opposed to traditional views.

    Defect investigation of undoped wide bandgap materials: Comparison between charge transient spectroscopy (QTS) and inverse Laplace QTS2025In: Journal of Applied Physics, ISSN 0021-8979, E-ISSN 1089-7550, Vol. 137, no 15, article id 155701Article in journal (Refereed)
    Abstract [en]

    Understanding the electrically active defects and impurities in semiconductors, especially in intrinsic or unintentionally doped wide bandgap materials, still remains a challenge. Here, time-of-flight (ToF) measurement using a solid state light source (355 and 213 nm) was performed on intrinsic silicon carbide and single-crystalline diamond. The charge transient spectroscopy (QTS) and the inverse Laplace (IL) QTS methods were applied to analyze the ToF results. Using these methods, we were able to trace the existing impurities in both materials. However, ILQTS proved to be more sensitive, with higher resolution for detection of existing multiple defects. The results suggest that this system can successfully be employed to investigate electrically active impurities at different energy states in highly resistive and undoped materials.

    The macroethics of science in a time of risis: Nobel Symposia, 1969‒19782025In: Notes and records of the Royal Society of London, ISSN 0035-9149, E-ISSN 1743-0178, p. 1-24Article in journal (Refereed)
    Abstract [en]

    In the mid-1960s the Nobel Foundation initiated a series of Nobel Symposia that continue to this day. These concerned areas associated with the Nobel Prizes in the sciences, literature, peace, and soon also economics. In 1969 the first of four ‘cross-cultural’ symposia was organized. This paper focuses on the first three of these (1969, 1974, 1978) and comments on the fourth (1983). These symposia were non-technical and focused on what was often described as ‘world problems’ considered at the time to constitute a serious global crisis, which included, for example, environmental degradation, nuclear threats, overpopulation and a diminishing status of science. An important ambition of the symposia, which failed, was to produce authoritative syntheses concerning the role of science in grappling with the global crisis, a consideration that is here described as ‘macroethical’. In conclusion, the sometimes-turbulent symposia are discussed in relation to ideas about reflexive modernization and associated phenomena (neoliberalism, innovation policy), seen as symptoms of the crisis and the criticism of traditional modernization theory that it helped trigger.
