  1. 16. Causes and Perceptions of Environmental Change in the Mangroves of Rufiji Delta, Tanzania : Implications for Sustainable Livelihood and Conservation

    Författare :Simon Mwansasu; Lars-Ove Westerberg; Annika Dahlberg; Ian Brown; Ian Bryceson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical Geography; naturgeografi;

    Sammanfattning : Mangroves are ecosystems with enormous ecological importance, supporting both terrestrial and marine food webs. They provide ecosystem services (e.g. food, medicines, fuel, constructing material) to communities near and far. LÄS MER

  3. 17. Finite Volume Methods on Quadrilateral and Moving Meshes

    Författare :Fredrik Svensson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; kontroll; systems; control; numerical analysis; finite volume method; Datalogi; Computer science; moving mesh method; higher order reconstruction; hyperbolic conservation law;

    Sammanfattning : The topic of this thesis is the study of finite volume methods for hyperbolic conservation laws on non-uniform meshes. A high-order hyperbolic reconstruction method is presented. The method is constructed for quadrilateral meshes, since more realistic hyperbolic problems involve more complicated problem domains than the standard rectangular ones. LÄS MER

  5. 19. In a Man´s World : Tolkninger av lovbrudd gjort i langtransportens yrkeskontekst

    Författare :Vanja Lundgren Sørli; Henrik Tham; Eva Tiby; Kjersti Ericsson; Stockholms universitet; []
    Nyckelord :structures; gender; masculinity; normalization; Key words: Long-distance trucking; occupational crime; techniques of neutralization; ; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : Criminological studies have shown that economical and/or occupational crimes are committed within all examined trades and occupations. This is also a fact in the gendered occupational context the Norwegian and Swedish long-distance trucking trade constitutes. LÄS MER

  7. 20. Protecting forests through partnerships

    Författare :Ulrika Widman; Camilla Sandström; Eeva Primmer; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; forests; formal protection; forest owners; public-private partnerships; Nature Conservation Agreements; the Komet program; forest governance; Sweden; statskunskap; political science;

    Sammanfattning : This thesis addresses the potential of private-public partnerships (PPPs) to involve private forest owners in formal forest protection. These partnerships have been widely advocated as means to engage actors from diverse sectors in collaborative new relationships, formed in a step-wise manner, to improve management of resources that combine public and private goods.
