  1. 6. Indirect effects of unemployment and low earnings : Crime and children's school performance

    Författare :Anna Nilsson; Jonas Agell; Rudolf Winter-Ebmer; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of three self-contained essays that consider indirect effects of unemployment and low earnings on crime and children’s school performance. The first essay, Crime, unemployment and labor market programs in turbulent times (joint with Jonas Agell), investigates the effect of unemployment and participation in labor market programs, in general and among youth, on Swedish crime rates using a new panel data set for Swedish municipalities for the period 1996-2000.

  3. 7. Microplastics in the aquatic environment: Insights into biological fate and effects in fish

    Författare :Giedrė Ašmonaitė; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics; nanoplastics; plastic pollution; effects; fish; chemical mixtures; ecotoxicology;

    Sammanfattning : According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. It has been predicted that up to 12 million tons of plastic waste reach the aquatic environment annually. LÄS MER

  4. 8. Indirect effects of predation in human-modified landscapes

    Författare :Ellinor Sahlén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Large carnivores affect prey species, with cascading effects on entire ecosystems. In anthropogenic regions large carnivores come into conflicts with humans, especially in rural areas where farming and hunting traditions are widespread. As a result, large carnivores have been eradicated from many regions across their historical distribution. LÄS MER

  5. 9. Extinctions in Ecological Communities : direct and indirect effects of perturbation on biodiversity

    Författare :Alva Curtsdotter; Bo Ebenman; Peter Münger; Elisa Thébault; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the dawning of what may become Earth’s 6th mass extinction the topic of this thesis, understanding extinction processes and what determines the magnitude of species loss, has become only too relevant. The number of known extinctions (~850) during the last centuries translates to extinction rates elevated above the background rate, matching those of previous mass extinction events. LÄS MER

  7. 10. Effects of Dark Matter in Astrophysical Systems

    Författare :Stefan Clementz; Mattias Blennow; Tommy Ohlsson; Riccardo Catena; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark matter; Self-interactions; solar capture; helioseismology; inelastic dark matter; direct detection; indirect detection; Fysik; Physics;

    Sammanfattning : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.
