  1. 1. Organizational Lessons Learned Natural Hazards Affecting Critical Infrastructure

    University dissertation from Karlstad : Karlstads universitet

    Author : Monika Rydstedt Nyman; Karlstads universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural hazards; critical infrastructure; feedback; lessons learned; collective learning; memory building; Risk and Environmental Studies; Risk- och Miljöstudier;

    Abstract : This thesis focuses on an issue often presented as a solution – albeit a debated one ­– namely learning, specifically lessons learned from natural hazard events. Empirically, this thesis examines flooding and avalanches in a Swedish context, centering on systematic feedback mechanisms and learning from extreme events. READ MORE

  2. 2. Environmental and health hazards of chemicals in plastic polymers and products

    University dissertation from Karlstad : Karlstads universitet

    Author : Delilah Lithner; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plastics; plastic products; plastic polymers; consumer products; environmental hazards; environment; health hazards; human health; hazard ranking; hazard assessment; chemical ranking; hazard identification; hazard classifications; hazardous chemicals; hazardous substances; toxic substances; monomers; polymers; toxicity; acute toxicity; toxicity tests; Daphnia magna; Toxicity Identification Evaluation; TIE; leaching; leachates; product leachates; leaching tests; plastic materials; plastic;

    Abstract : Plastics are extremely diverse in terms of chemical composition, properties and possible applications, and are widely distributed in the society and the environment. In the last 15 years the global annual production has doubled, reaching 245 million tons in 2008. READ MORE

  3. 3. Hazards of Drug Therapy On the Management of Adverse Drug Reactions: From Signal Detection and Evaluation to Risk Minimization

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karin Hedenmalm; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; adverse drug reactions; spontaneous reporting systems; drug regulation; pharmacovigilance; incidence; Farmakologi; MEDICINE Physiology and pharmacology Pharmacological research; MEDICIN Fysiologi och farmakologi Farmakologisk forskning;

    Abstract : Spontaneous reporting systems (SRSs) for adverse drug reactions (ADRs) have been developed as a result of the thalidomide disaster, whereby thousands of children world-wide were born with birth defects. The Swedish Adverse Drug Reactions Advisory Committee was established in 1965. READ MORE

  4. 4. Evaluation and Mitigation of Industrial Fire Hazards

    University dissertation from Department of Fire Safety Engineering and Systems Safety, Lund University

    Abstract : A tool suitable for conducting industrial fire and explosion hazard analysis is presented, together with an identification of weak links in the hazard evaluation chain. For some of the weak links additional research has been carried out. READ MORE

  5. 5. Essays on the Assumption of Proportional Hazards in Cox Regression

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Inger Persson; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Proportional hazards; Cox regression; Proportionality assumption; Informatik; data- och systemvetenskap; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap; statistik; Statistics;

    Abstract : This thesis consists of four papers about the assumption of proportional hazards for the Cox model in survival analysis. The first paper compares the hazard ratio estimated from the Cox model to an exact calculation of the geometric average of the hazard ratio when the underlying assumption of proportional hazards is false, i.e. READ MORE
