  1. 1. Fighting for Aid : Foreign Funding and Civil Conflict Intensity

    Författare :Daniel Strandow; Magnus Öberg; Michael G. Findley; Kristian Skrede Gleditsch; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aid; foreign aid; foreign assistance; relief; humanitarian; conflict; civil war; civil conflict; geographic concentration; intra-state; violence; military; contest; low-intensity; guerrilla; irregular; conventional; decision theory; contest success function; geo-coding; geo-referencing; territorial control; propensity score; Africa; South of the Sahara; Peace and Conflict Research; Freds- och konfliktforskning;

    Sammanfattning : This dissertation focuses on the sub-national impact of foreign aid on civil conflicts by asking the question: How does foreign aid committed to contested areas affect the intensity of violence in those areas? The main theoretical contribution is to focus on how aid influences warring parties’ decisions to engage in contests over territorial control and how that in turn influences violence intensity. The study introduces two concepts: funding concentration and barriers to exploiting aid. LÄS MER

  3. 2. Costa Rican coffee and bananas : A social-ecological study of management practices and their effects on the environment

  5. 4. Downstream migration of salmonids in regulated rivers : Non-conventional methods for fish diversion

    Författare :Johan Leander; Jonatan Klaminder; Micael Jonsson; Gustav Hellström; Paul Kemp; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fish migration; Fish passage; Fish guidance; Hydropower; Atlantic salmon; Brown trout; Bubble barrier; Non-physical barrier;

    Sammanfattning : Passages through hydropower plants can be fatal for downstream migrating salmonids (Salmo spp.). This is particularly true for large adults that are returning to the ocean after spawning. LÄS MER

  7. 5. Photocatalysis beyond conventional precious metal complexes

    Författare :Rickard Lindroth; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Sammanfattning : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. LÄS MER
