    Base-catalyzed Stereospecific Isomerizations via 1,3-Proton Shift : Synthesis of Chiral Amines, Enamides and Siloxyallenes

    No full text
    The thesis focuses on the development of organocatalytic methods to efficiently generate novel enantioenriched products. The different projects are united by the utilization of base catalysis, which promotes the isomerization of allylic- and propargylic compounds in a stereospecific manner. The effective chirality transfer processes give access to a variety of functionalized compounds with potential applications in drug discovery.  The first project of this thesis demonstrates that a simple bicyclic guanidine base, namely 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD), enables the stereospecific isomerization of α-chiral allylic amines (Paper I). The resulting enamine–imine tautomeric mixture is directly exploited in a one-pot sequence through diastereoselective reduction with DIBAL-H, enabling the preparation of a wide array of α,-γ-chiral γ-trifluoromethylated aliphatic amines. This method offers a new and efficient entry to functionalized chiral amines.  The second project presents a different strategy that further highlights the synthetic potential of the abovementioned enamine-imine tautomeric mixture (Paper II). Therein, acyl chlorides were subsequently added in a one-pot fashion to access a new class of γ-chiral trifluoromethylated enamides. A broad library of such compounds was synthesized with different substituents and functional groups. A variety of chemical transformations were performed to obtain novel chiral complex scaffolds. This thesis also explores TBD as an organocatalyst able to promote central-to-axial chirality transfer through stereospecific isomerization of protected propargylic alcohols into axially chiral siloxyallenes (Paper III). A potential application was demonstrated, and the reaction mechanism has been theoretically investigated by DFT calculations.  In the last project, multiple chiral base catalysts were evaluated to establish an asymmetric isomerization of allylic compounds via kinetic resolution (Project IV). Thereby, extensive optimization studies were carried out to identify suitable reaction conditions. An efficient design of key control experiments led us to suggest a plausible reaction mechanism

    Syftet med undersökningen är att få en ökad förståelse av Social och Emotionell Träning (SET) inom daglig verksamhet, både utifrån ett organisatoriskt och ett individuellt perspektiv. Forskning visar att individer med funktionsnedsättning har utmaningar att etablera sig på arbetsmarknaden. Studien är bestående av elva semistrukturerade intervjuer, två observationer samt ett dokument från företaget. Materialet har tolkats med hjälp av tematiska och narrativa analysmetoder. Resultaten visar att SET fungerar som en gruppinriktad metod och träning med en delvis koppling till arbetslivet. Metoden kan ha positiv inverkan på målgruppen avseende att främja anställningsbarhet, vilket både var bundet till innehållet och strukturen såväl som träningen i praktiken och kontexten. Återkommande upplevelser och effekter av SET var ökad social förmåga och delaktighet samt förbättrad hantering av stressfyllda och utmanande situationer. Andra aspekter var en känsla av att bli sedd och hörd, ökad struktur i vardagen samt en gruppgemenskap. The aim of the study is to gain an increased understanding of Social and Emotional Training (SET) within daily worklike-activities, from an organizational and individual perspective. Through research it is shown that individuals with disabilities are experiencing challenges in establishing themselves in the labor market. The study consists of eleven semi-structured interviews, two observations and a document from the company. The material has been interpreted using thematic and narrative analysis methods. The results are showing that SET functions as a group-oriented method and training with a partial connection to working life. The method can have a positive impact on the target group regarding promoting employability, which was both tied to the content and structure as well as the training in practice and context. Recurring experiences and effects of SET were increased social ability and participation as well as improved handling of stressful and challenging situations.

    Power and Landscape in Late Iron Age Uppland : A Study of Nordian's Mound and the Åshusby Burial Ground

    No full text
    This bachelor’s thesis exmines Nordian’s Mound and the Åshusby burial ground in order to explore the site’s function and significance during the Late Iron Age. The study combines archaeological material, landscape analysis and theoretical perspectives on power, monuments and networks. The results suggest that Nordian’s mound functioned as more than an individual burial and should be interpreted as a monument with the local social elite. Its prominent placement on the Stockholm esker and near prehistoric waterways indicates that landscape and visibility played a decisive role in its location. The archaeological material further indicates that the site was used by elites during several periods between approximately AD 500 and 900. Overall, the study highlights how monuments, landscape and regional networks interacted in the construction of social meaning during the Late Iron Ag

    "När Washington nyser blir en kirgisisk journalist sjuk" : Demokrati i Centralasien och Trumpadministrationens nedstängning av Radio Free Europe/Radio Liberty

    No full text
    Uppsatsen undersöker hur den sittande Trumpadministrationens beslut påverkar förutsättningar för demokrati och fri media långt bort från Washington – i Centralasien. Genom intervjuer och ett omfångsrikt material av medierapportering och rapporter tecknar uppsatsen en bild av vilka konsekvenser nedstängningen av Radio Free Europe/Radio Liberty får i Kazakstan, Kirgizistan och Uzbekistan. Den empiriska analysen visar på en känslig mediesituation som genomsyras av statlig påverkan och olika former av begränsningar för opartisk media. Nedstängningen av Radio FreeEurope/Radio Liberty riskerar att göra medieklimatet i Centralasien ännu mer begränsat och farligare för oberoende journalister. Det empiriska resultatet tolkas mot bakgrund av en teoribaserad diskussion om hur bristen på fri media påverkar förutsättningarna för demokrati. Den teoretiska slutsatsen visar att en minskad åsiktsflora reducerar möjligheterna för deliberativ demokrati och polyarkisk demokrati i Centralasien

    Visible transition: invisible harm? : Assembling the Green Deal and local realities in Luleå and Kiruna

    No full text
    This thesis examines how the European Green Deal is assembled and materialized at the local level in northern Sweden and how this process generates uneven forms of contestation and harm. Focusing on the Arctic municipalities of Kiruna and Luleå, the study conceptualizes the green industrial transition not as a linear or purely technological shift, but as a sociotechnical and political assemblage constituted through heterogeneous actors, infrastructures, and policies operating across European, national, regional, and municipal scales. While northern Sweden is increasingly framed as indispensable for Europe’s decarbonization, particularly through green steel production and critical raw material extraction, this strategic positioning obscures how costs and risks are redistributed locally. The thesis addresses two research questions: how the green industrial transition is assembled in Kiruna and Luleå, and what forms of contestation and violence emerge through this process. To answer these questions, it combines Actor–Network Theory and Assemblage Thinking with the concepts of slow violence and extractive violence in a theoretical framework. Methodologically, the thesis employs a qualitative multiple instrumental case study design based on document and media analysis of EU and Swedish policy documents, municipal planning materials, corporate reports, environmental permitting decisions, and regional news coverage. The analysis demonstrates that the green transition assemblage is fragile, contested, and shaped by persistent extractivist legacies. In Kiruna, the expansion of mining and the development of rare earth extraction are tightly entangled with the large-scale relocation of the city itself and the reconfiguration of surrounding landscapes, intensifying long-standing conflicts over Sámi land use and decision-making authority. In contrast, Luleå’s role as an industrial processing and logistics hub gives rise to more diffuse and incremental forms of harm, as industrial reconfiguration generates cumulative pressures on housing provision, energy systems, infrastructure, and municipal finances, which materialize over time as latent and cumulative forms of violence. The thesis concludes that, without addressing these relational power asymmetries and cumulative harms, the green industrial transition risks reproducing, and increasing existing inequalities while being contested in itself

    Quantifying the balance between dissociation and radiative cooling in interstellar PAHs

    No full text
    Polycyclic aromatic hydrocarbons (PAH) constitute an ubiquitous class of organic molecules in the interstellar medium. In recent years, they have also been detected in cold molecular clouds through radio astronomical surveys, while observations from the James Webb Space Telescope have enabled their spatial distributions and abundances to be characterized in unprecedented detail. Despite this, the stability of PAHs under astrophysical conditions remains poorly constrained. For instance, astrochemical models that simulate the abundances of aliphatic hydrocarbons in molecular clouds underestimate PAH abundances by several orders of magnitude. The main limitation in these models is that they are built on theoretical assumptions that lack experimental verification.  This licentiate thesis presents laboratory studies of indene, indenyl, and 2-cyanoindene monocations, PAHs whose neutral counterparts have been detected or are suspected to be present in the molecular cloud, TMC-1. The balance between dissociation and radiative cooling was investigated through absolute dissociation rate measurements performed using a cryogenic ion beam storage ring at the DESIREE facility. For cyanoindene, complementary dissociative photoionisation experiments were carried out at the DESIRS beamline of the SOLEIL synchrotron. The measured absolute dissociation rates and breakdown curves were interpreted using a statistical framework based on microcanonical rate coefficients for all relevant unimolecular processes. The results provide quantitative constraints on PAH stability and are discussed in the context of their implications for astrochemical modelling. In particular, the results demonstrate that radiative cooling plays a decisive role under astrophysically relevant excitation conditions, significantly reshaping the balance between energy loss and fragmentation, challenging the current simplified treatments of PAH stability

    The FAIR-Blockchain Nexus : A Framework for AI-driven Digital Transformation in the Public Sector

    No full text
    Public organisations are undergoing rapid digital transformation aimed at enhancing service efficiency, transparency, and accountability. However, persistent challenges remain in managing and reusing data across agencies, as well as in ensuring trust and explainability within Artificial Intelligence (AI)–driven systems. This study examines how the principles of FAIR data management (Findable, Accessible, Interoperable, Reusable) and blockchain technologies can be operationalised within public sector enterprise models to enable transparent, sovereign, and trustworthy AI adoption. Guided by the Technology–Organisation–Environment (TOE) framework and Dynamic Capabilities theory, we conducted a qualitative analysis of interview data from multiple government organisations engaged in AI readiness and digital transformation initiatives. The findings indicate that FAIR and blockchain-related practices are emerging as key enablers of interoperability, provenance, auditability, and data sovereignty. Based on the result of a thematic analysis and theoretical synthesis, the study proposes an enterprise modelling framework that integrates FAIR principles and blockchain mechanisms across the TOE dimensions to support transparent and sovereign AI-driven transformation. The study contributes an actionable model for policymakers and practitioners seeking to align governance, data infrastructure, and technological innovation within public digital ecosystems
