   Författare :Muhammad Sarfraz Iqbal; Dik van de Meent; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; multimedia fate modeling; uncertainty analysis; probability bounds analysis; fuzzy arithmetic; chemical safety assessment; REACH;

   Sammanfattning : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. LÄS MER

   Sammanfattning : Essay 1 - We examine whether risk aversion as well as higher order risk attitudes (HORAs) (prudence and temperance) have changed during COVID-19. We include prudence and temperance as higher order measures, as these two have been largely understudied under extreme events but are determinants of decisions related to the health and financial domains.

7. 20. Mining Futures : Predictions and Uncertainty in Swedish Mineral Exploration

   Författare :Tobias Olofsson; Patrik Aspers; Gholamreza Azarian; Trine Pallesen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uncertainty; Risk management; Sociology of the Future; Valuation; Justification; Mineral Exploration; Second Nature; Natural Resources; Sociologi; Sociology;

   Sammanfattning : Any forward-oriented enterprise must somehow manage the challenges posed by uncertainty and with its distant temporal horizons, high stakes, and low probability of success, mineral exploration is a good illustration of this general rule. Based on a combination of interviews, observations, and archival research, this thesis investigates how explorationists use predictions to manage the material complexities and the uncertainties that contribute to determining the future minability of mineral deposits.
