1. 11. A View from Language : Growth of language in individuals and populations

   Författare :Christer Johansson; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Scandinavia; psycho-linguistics; past tense; linguistic ecology; language variation; language change; language acquisition; evolution; epidemics; emergence; diffusion; connectionism; area linguistics; case; simulation; synthesis.; Linguistics; Lingvistik;

   Sammanfattning : The main question that this book tries to find answers to is what it is that makes language learnable. Language is one of the most complex human activities, but nearly 100% of humanity have learned a language in childhood. One answer could be that it is something in our brain that makes us learn language better than most other activities. LÄS MER

3. 12. Modelling the Evolution of Species’ Ranges

   Författare :Martin Eriksson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Range expansions; Range margins; Population genetics; Evolutionary biology; Local adaptation; Environmental selection; Phenotypic plasticity; Computer simulations;

   Sammanfattning : The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. LÄS MER

4. 13. Unveiling Catalytic Species in Suspension/Solution-Based Reactions by In Situ X-Ray Absorption Spectroscopy : Evolution of Palladium and Ruthenium Species

   Författare :Ning Yuan; Xiaodong Zou; Ingmar Persson; Gopinathan Sankar; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium and ruthenium species; Catalysts; Suspension and solution; In situ X-ray absorption spectroscopy; Activation; Deactivation; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : The palladium (Pd) and ruthenium (Ru) species in several attractive catalysts have been probed using X-ray absorption spectroscopy (XAS). The study of catalyst evolution in suspension- and solution-based reactions was the primary aim. It was achieved by performing in situ XAS experiments on Pd and Ru over the course of the reactions.

5. 14. The diapause switch : Evolution of alternative developmental pathways in a butterfly

   Författare :Inger Marie Aalberg Haugen; Karl Gotthard; Dan Hahn; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental plasticity; phenotypic plasticity; developmental switch; threshold trait; life-cycle regulation; direct development; Lepidoptera; zoologisk ekologi; Animal Ecology;

   Sammanfattning : Diapause decision is a classic example of a threshold switch mechanism with cascading effects on morphology, behaviour and life-history traits. This thesis addresses the downstream effects of the insect diapause switch, with the main focus on pathway-specific regulation of life-history traits, using the speckled wood butterfly (Pararge aegeria) as a study species.

7. 15. Anti-Dumping Law of WTO/GATT and EC: Gradual Evolution of Anti-Dumping Law in Global Economic Integration

   Författare :Wenxi Li; Juridiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; like products; domestic industry; threat of material injury; material injury; export price; normal value; Basic Regulation; GATT Anti-Dumping Code; GATT; dumping; anti-dumping law; anti-dumping procedure; global economic integration; European law; EU-rätt;

   Sammanfattning : The aim of this study is to demonstrate and evaluate the current anti-dumping law as formed by the WTO/GATT law (GATT law) and implemented by the EC law against the background of global economic integration. Over centuries, international trade has involved a controversial business behaviour, “dumping”. LÄS MER
