2. 1. Social learning in the Anthropocene : Governance of natural resources in human dominated systems

   Author : Björn Nykvist; Jon Norberg; Marianne Krasny; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; social learning; multi-level governance; resilience; adaptability; natural resource management; institutions; policy making; impact assessments; naturresurshushållning; Natural Resources Management;

   Abstract : We live in the Anthropocene – an age where humans dominate natural systems – and there is ample evidence that our current practices degrade the capacity of natural systems to provide us with natural resources. How we, as humans, organize and learn, in communities and among state and other societal actors, constitute a decisive factor for both local management of natural resources and the functioning of the planet Earth.

4. 2. Violent natural resource conflicts : From definitions to prevention

   Author : Marie K. Schellens; Belyazid Salim; Stefano Manzoni; Silja Bára Ómarsdottir; Päivi Lujala; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural resource conflicts; natural resources; violent conflict; criticality; definition; predictive modelling; early warning; causal network; prevention; Physical Geography; naturgeografi;

   Abstract : General scientific consensus is growing that natural resources play an important role in violent conflicts. Both scarcity and abundance contribute to violent conflict, depending on the socio-economic and political conditions at play. READ MORE

5. 3. Ticks - ecology, new hazards, and relevance for public health

   Author : Thérese Janzén; Monica Hammer; Patrik Dinnétz; Mona Petersson; Lars Korslund; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea region; eco-epidemiology; habitat; Ixodes persulcatus; Ixodes ricinus; landscape; risk; urbanization; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

6. 4. Convergence in mixed reality-virtuality environments : facilitating natural user behavior

   Author : Daniel Johansson; Leo J. de Vin; Morten Fjeld; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mixed reality. augmented reality; augmented virtuality; head mounted display; omnidirectional floor; natural interface; telepresence; Datalogi; Computer and Systems Science;

   Abstract : This thesis addresses the subject of converging real and virtual environments to a combined entity that can facilitate physiologically complying interfaces for the purpose of training. Based on the mobility and physiological demands of dismounted soldiers, the base assumption is that greater immersion means better learning and potentially higher training transfer. READ MORE

7. 5. Modelling of the Fletcher-Gent effect and obtaining hyperelastic parameters for filled elastomers

   Author : Rickard Österlöf; Leif Kari; Per-Erik Austrell; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; filled elastomers; natural rubber; carbon black; Fletcher-Gent effect; Payne-effect; finite strain; hyperelastic;

   Abstract : The strain amplitude dependency , i.e. the Fletcher-Gent effect and Payne effect, and the strain rate dependency of rubber with reinforcing fillers is modelled using a modified boundary surface model and implemented uniaxially. READ MORE
