2. 11. Accidents between pedestrians, bicyclists and motorized vehicles: Accident risk and injury severity

   Author : Höskuldur Kröyer; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accidents; pedestrians; bicyclists; exposure; risk; consequence; speed; age.;

   Abstract : The aims of this work are to better understand (1) the relation between exposure and the risk of an accident between pedestrians and motorized vehicles and between bicyclists and motorized vehicles occurring at urban intersections and (2) how the speed environment and the victim´s age relate to the injury severity/outcome once a pedestrian or a bicyclist has been struck by a motorized vehicle. Cross sectional studies are used, and the relations are analyzed using multinomial logit models, negative binomial regression and other statistical methods. READ MORE

4. 12. Nonmalignant health effects of arsenic exposure

   Author : Mahfuzar Rahman; Per Gustavsson; Linköpings universitet; []
   Keywords : arsenic; case-control study; cross-sectional study; diabetes mellitus; drinking water; epidemiology; exposure; keratosis; public health. hypertension; risk factors; MEDICINE; MEDICIN;

   Abstract : This thesis comprises a series of studies concerning occupational and environmental exposure to arsenic and some novel chronic health effects of this element, namely diabetes mellitus and hypertension. Substantial prevalence of the well-known skin manifestations of arsenic ingestion was also found to occur as a result of environmental exposure through drinking water. READ MORE

5. 13. Ethical Aspects of Radiation Risk Management

   Author : Per Wikman-Svahn; John Cantwell; Carl F. Cranor; KTH; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; radiation protection; radiological protection; nuclear power; nuclear energy; social issues; ethical issues; ethics; risk; uncertainty; value judgments; precautionary principle; distributive issues; justice; limits; prioritarianism; responsibility; egalitarianism; black swan; black elephant; risk management;

   Abstract : This thesis is based on the assumption that the intersection of moral philosophy and practical risk management is a rewarding area to study. In particular, the thesis assumes that concepts, ideas, and methods that are used in moral philosophy can be of great benefit for risk analysis, but also that practices in risk regulation provide a useful testing ground for moral philosophical theories.

6. 14. Contributions to Emission, Exposure and Risk Assessment of Nanomaterials

   Author : Rickard Arvidsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; particle flow analysis; emission assessment; titanium dioxide; graphene; silver; risk assessment; exposure assessment; Nanomaterials; substance flow analysis.;

   Abstract : In recent years, synthetic nanomaterials have begun to be produced and used in increasingly larger volumes. These materials may cause new or increased risks to the environment, but no harmonized methods for structured assessment of their environmental risks exist. READ MORE

7. 15. Chemical exposure in the work place : mental models of workers and experts

   Author : Anita Pettersson-Strömbäck; Bengt Järvholm; Steven Nordin; Bo Strangert; Marianne Törner; Umeå universitet; []
   Keywords : self-assessment of exposure; predictions; expert judgment; risk; interpretation; time series analysis; MAPE; benzene; monoterpenes; styrene; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Many workers are daily exposed to chemical risks in their work place that has to be assessed and controlled. Due to exposure variability, repeated and random measurements should be conducted for valid estimates of the average exposure. READ MORE
