   Author : Madeleine Hayenhjelm; Sven Ove Hansson; Ingar Brinck; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Risk communication; two-way communication; democratic approach; equality; asymmetry; vulnerability; trust; Philosophy subjects; Filosofiämnen;

   Abstract : This thesis is a philosophical contribution to the theories on risk communication. The topic of risk communication is approached from several different angles, but with a normative focus on equality and vulnerability. Essay I is a comment on risk perception theory and the psychometric model in particular. READ MORE

4. 2. Signal Processing Aspects of Bistatic Backscatter Communication

   Author : Ahmet Kaplan; Erik G. Larsson; Diana Moya Osorio; Musa Furkan Keskin; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Passive Internet-of-Things (IoT), a new paradigm based on battery-free devices, is a promising technology to enable several use cases that require connectivity with stringent requirements in terms of cost, complexity, and energy efficiency. These use cases span critical sectors, such as healthcare, transportation, and agriculture. READ MORE

   Abstract : Modern society is dependent on communications and the developments of these increases constantly through a seemingly endless demand for communication services and thereby synchronization and time. This is confirmed by a vast range of research on communications, irrespective of technology and protocol. READ MORE

7. 5. Risk communication in multi-stakeholder disaster risk management systems : Insights and recommendations from the Swedish system

   Author : Lexin Lin; Avdelningen för Riskhantering och Samhällssäkerhet; []
   Keywords : multi-level DRM system; risk communication; Sweden; disaster risk management DRM ; risk assessment; communication challenges; ; multi-stakeholder;

   Abstract : The overall purpose of this thesis is to improve our understanding of how disaster risk management (DRM) systems function. Specifically, it aims to increase our knowledge about effective communication in a multi-stakeholder, multi-level DRM system, with a particular focus on the exchange of risk-related information for risk assessment.
