  1. 1. One coin - One vote : the rural political power shift that pushed Sweden towards industrialization

    Författare :Erik Lindgren; Björn Tyrefors; Per Pettersson-Lidbom; Erik Grönqvist; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Development; Education; Infrastructure Investment; Railroads; Historical data; Political Institutions; Infant mortality and Weather; Growth; Economics; nationalekonomi;

    Sammanfattning : The Causal Effect of Political Power on the Provision of Public Education: Evidence from a Weighted Voting SystemWe estimate how political power affects the provision of public education in local governments, using data from a nondemocratic society where voters received votes in proportion to their taxable income. This was the system used in Swedish local governments during the period 1862–1909. LÄS MER

  3. 2. Unraveling the importance of solid and adsorbed phase mercury speciation for methylmercury formation, evasion and bioaccumulation

    Författare :Sofi Jonsson; Erik Björn; Ulf Skyllberg; Erik Lundberg; Per Persson; Robert Mason; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mercury; methylmercury; aquatic systems; estuary; Hg; MeHg; bioaccumulation; methylation; demethylation; evasion; sediment; water; terrestrial sources; atmospheric sources; climate change; eutrophication;

    Sammanfattning : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. LÄS MER

  4. 3. Mot nätverkssjukvård i komplex miljö : - behov av en vetenskaplig syn på ledning för säker vård och effektiv resursanvändning

    Författare :Marianne Lagerstedt; Björn-Erik Erlandsson; Niklas Hallberg; Erik Bjurström; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Patient safety; casestudy; safety; networked healthcare; command and control; concept; direction and coordination; Technology and Health; Teknik och hälsa;

    Sammanfattning : Since 2008 advanced home healthcare agencies (ASiH) in a larger Swedish county council has underwent a transformation, to become part of a coming concept: networked healthcare (NVS). NVS means that intermediate multi-organizational healthcare (IMV) will be produced often in the home, and from 2013 to an increasing number of patients in different age groups with different diagnoses and medical conditions - in large variability of needs.

  5. 4. Light treatment in seasonal and nonseasonal depression : diagnostic, clinical and neurendocrine studies

    Författare :Björn-Erik Thalén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Depression; seasonal; nonseasonal; light treatment; clinical ratings; melatonin; cortisol; ACTH; CRH; dexamethasone suppression testBj rn-Erik Thalen; 1996Printed in Sweden by Repro Print; Stockholm.;

    Sammanfattning : There is a need for evaluation of new treatment modalities in depression. The aims of this thesis were to investigate the effect of 2 hours of daily light treatment for 10 days in patients with a major depression with seasonal or nonseasonal pattern and to study subgroups of depressed patients with respect to clinical, demographic, and neuroendocrine factors, the effect of exposure to bright light, dexamethasone suppression test, CRH stimulation and the hormonal effect of light exposure on healthy controls.

  7. 5. Phase transitions in magnetic metamaterials

    Författare :Björn Erik Skovdal; Björgvin Hjörvarsson; Vassilios Kapaklis; Gunnar K. Pálsson; Peter Schiffer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic metamaterials; artificial spin ice; mesospins; magnetic nanostructures; mesoscopic spin systems; multiscale materials; tri-criticality; emergence; edge modes;

    Sammanfattning : Magnetic metamaterials consisting of arrays of densely packed, two-dimensional nanoscale magnetic islands have degrees of freedom on two separate length scales: inside the islands, and among them. These degrees of freedom can be tuned by e.g. size, shape, island separation and lattice geometry. LÄS MER
