  1. 1. Essays on Measurement Error and Nonresponse

    Författare :Fredrik Johansson; Anders Klevmarken; Per Johansson; Markus Jäntti; Uppsala universitet; []
    Nyckelord :Economics; Nationalekonomi;

    Sammanfattning : Essay 1 deals with measurement errors. Matching survey data with administrative records provides unique opportunities to evaluate the statistical properties of respondents' answers. This paper focuses primarily on home ownership and wealth variables. LÄS MER

  3. 2. Complex source modeling for electromagnetic dosimetry

    Författare :Markus Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; phase-retrieval; source modeling; dosimetry; SAR;

    Sammanfattning : Electromagnetic modeling of complex sources is useful in dosimetry applications as well as for near-field to far-field transformations and antennadiagnostics. In order to determine whether exposure safety guidelines, such as the EU directive 2004/40/EC, are complied with, it is important to be able tomodel the field distribution from electromagnetic sources.

  4. 3. Effects of Agriculture on Abundance, Genetic Diversity and Fitness in the Common Frog, Rana temporaria

    Författare :Markus Johansson; Anssi Laurila; Juha Merilä; Craig R. Primmer; Michael W. Bruford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; agriculture; agrochemicals; amphibians; effective population size; genetic diversity; genetic structure; hierarchical sampling; microsatellites; Rana temporaria; Biologi; Biology; Biologi;

    Sammanfattning : The aims of this thesis were to evaluate the effects of agriculture on amphibians in terms of (i) population genetic consequences of agriculture-induced spatial changes of the landscape and (ii) local adaptation and tolerance to frequently used agrochemicals. The study was performed using the common frog Rana temporaria as a model. LÄS MER

  5. 4. Entanglement and Quantum Computation from a Geometric and Topological Perspective

    Författare :Markus Johansson; Marie Ericsson; Jens Eisert; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Information; Geometric Phases; Topological Phases; Entanglement; Quantum Computation;

    Sammanfattning : In this thesis we investigate geometric and topological structures in the context of entanglement and quantum computation.A parallel transport condition is introduced in the context of Franson interferometry based on the maximization of two-particle coincidence intensity.

  7. 5. Negotiations as Usual. Putting Domestic Constraints on the Table in the Council of the European Union

    Författare :Markus Johansson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Negotiations; Council of the European Union; Domestic constraints; Two-level games;

    Sammanfattning : The argument developed in this thesis is that negotiations in the Council of the European Union cannot be understood in isolation from the domestic politics of the member states. Building on the logic of Robert Putnam’s two-level game theory, and the fact that negotiated EU agreements need to gain support from vital parts of the governments’ domestic constituencies, government negotiators are constrained by their domestic political actors.
