   Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; safety factor; safety margin; uncertainty factor; uncertainty function; uncertainty; information; risk; risk assessment; risk management; epistemology; science; reasoning;

   Sammanfattning : Uncertainty is, it seems, more or less constantly present in our lives. Even so, grasping the concept philosophically is far from trivial. In this doctoral thesis, uncertainty and its conceptual companion information are studied. Axiomatic analyses are provided and numerical measures suggested. LÄS MER

3. 2. Is it safe? safety factor reasoning in policy-making under uncertainty

4. 3. Environmental Modelling : Learning from Uncertainty

   Författare :John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

   Sammanfattning : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. LÄS MER

   Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER
