  1. 21. Safeguarding nature and people : Integrating economics, politics, and human rights to transform biodiversity policies and governance

    Författare :Niak Sian Koh; Thomas Hahn; Claudia Ituarte-Lima; Wiebren J. Boonstra; Grace Wong; Esther Turnhout; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; global environmental governance; human rights review mechanisms; biodiversity offsets; commensurability; commodification; economic instruments; transformations; Convention on Biological Diversity; compliance; safeguards; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : None of the world’s biodiversity goals from the last decade were fully met, as biodiversity losses are occurring at an unprecedented rate. Policies are not always effective; their use may have adverse effects on people and nature. LÄS MER

  3. 22. Institutions, Inequality and Societal Transformations

    Författare :Sara Moricz; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gender Norms; Metoo; Sweden; LSTM Neural Network; Asia; Indonesia; Democracy; Elections; Economic Growth; Income Inequality; Economic Development;

    Sammanfattning : Institutions matter for economic development. This thesis consists of three self-contained articles which provide different contributions to institutional economics.The first article studies short-run changes in gender norms. It takes advantage of recent developments in machine learning algorithms to study changes in norms in Swedish tweets. LÄS MER

  4. 23. On Peritectic Reactions and Transformations and Hot Forming of Cast Structures

    Författare :Hani Nassar; Hasse Fredriksson; Rian Dippenaar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; peritectic reactions; massive transformations; thermal analysis; Fe-base alloys; steels; growth irregularities; hot forming; compression testing; flow stress; grain size.; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major cause of crack-formation in many steels, thus, good knowledge of the mechanisms by which these phenomena occur is essential for preventing such defects.

  5. 24. Synthesis and asymmetric transformations of diols by enzyme- and ruthenium catalysis

    Författare :Karin Leijondahl; Jan-Erling Bäckvall; Kurt Faber; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic kinetic asymmetric transformation; diols; enzymatic transformations; catalysis; ruthenium; transfer hydrogenation; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : The major part of this thesis describes the synthesis of aliphatic secondary diols and the development of lipase- and ruthenium-catalyzed asymmetric transformations of these diols. Several acyclic 1,4-diols and 1,5-diols were synthesized, and by combining a lipase-catalyzed asymmetric transformation with a ruthenium-catalyzed epimerization, enantiomerically- and diastereomerically enriched diacetates were obtained.

  7. 25. Tree Transformations in Inductive Dependency Parsing

    Författare :Jens Nilsson; Joakim Nivre; Pierre Nugues; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inductive Dependency Parsing; Dependency Structure; Tree Transformation; Non-projectivity; Coordination; Verb Group; Language technology; Språkteknologi; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Sammanfattning : This licentiate thesis deals with automatic syntactic analysis, or parsing, of natural languages. A parser constructs the syntactic analysis, which it learns by looking at correctly analyzed sentences, known as training data. The general topic concerns manipulations of the training data in order to improve the parsing accuracy. LÄS MER
