  1. 1. Crustal evolution of the Arabian–Nubian Shield : Insights from zircon geochronology and Nd–Hf–O isotopes

    Författare :Fitsum Girum Yeshanew; Victoria Pease; Martin J. Whitehouse; Robert J. Stern; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Gondwana; Arabian–Nubian Shield; Azania; zircon U–Pb–O–Hf isotopes; Nd isotopes; Cambrian Sandstones; juvenile; pre–Neoproterozoic; reworking; Geology; geologi;

    Sammanfattning : The Arabian–Nubian Shield (ANS) represents a major site of juvenile Neoproterozoic crustal addition on Earth and documents Neoproterozoic tectonics bracketed by two supercontinent cycles, namely the fragmentation of Rodinia and the amalgamation of Gondwana. There is general consensus that the ANS formed by juvenile magmatic arc accretion and subsequent shield–wide post–tectonic magmatism. LÄS MER

  2. 2. Evolution of continental crust in the Proterozoic : growth and reworking in orogenic systems

    Författare :Andreas Petersson; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; crustal reworking; Proterozoic; O-isotopes; Lu–Hf; U–Pb; zircon; Crustal growth;

    Sammanfattning : To understand the growth of continental crust, the balance between juvenile mantle derived extraction, infracrustal reworking and crustal recycling, needs to be estimated. Since the beginning of the century, the use of coupled in situ zircon U–Pb, Lu–Hf and O isotope analyses as a tool to address these questions have increased exponentially. LÄS MER

  3. 3. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Författare :Stina Lindqvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Sammanfattning : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). LÄS MER

  4. 4. Contentious countrysides : social movements reworking and resisting public healthcare restructuring in rural Sweden

    Sammanfattning : The broader aim of this thesis is to contribute to the understanding of the production and reproduction of spatial inequalities following from the restructuring of the public healthcare system. More specifically, by analyzing the contention around healthcare restructuring related to two cases spanning a longer period in northern Sweden, I aim to investigate the changing conditions for healthcare provision in rural and sparsely populated areas, and I explore the forms of collective action that local people engage in to sustain the access to healthcare, as well as how state authorities’ attitudes towards such collective action have shifted.

  5. 5. Det ansvarsfulla mötet : En närhetsetisk analys av omsorgens innebörder i förskolan

    Författare :Mie Josefson; Hillevi Lenz Taguchi; Sven Persson; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; care; responsibility; preschool; preschool teacher; ethics of care; proximity ethics; reworking qualitative data; omsorg; ansvar; förskola; förskolepedagog; omsorgsetik; närhetsetik; sekundär analys; Early Childhood Education; förskoledidaktik;

    Sammanfattning : This doctoral thesis embraces Care in the discipline of Early Childhood Education. In this thesis, the concept of responsibility is used to analyze the meaning of care in preschool. LÄS MER
