1. 1. Models of Cooperation, Learning and Catastrophic Risk

   Författare :Vilhelm Verendel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Backward Induction; Bayesian analysis; Finitely Repeated Prisoners Dilemma; Cooperation; Fermi Paradox; Learning; Climate negotiations; Catastrophic risk;

   Sammanfattning : Our world presents us with dangers and opportunities. Some of these dangers and opportunities are easier to handle if two or more individuals learn to cooperate. This thesis contributes five papers about cooperation, learning and catastrophic risk. LÄS MER

3. 2. Risk-Averse Decision-Making under Parametric Uncertainty

   Författare :Hannes Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Risk-Sensitive Learning; Autonomous Driving; Machine Learning; Uncertainty Estimation; Reinforcement Learning;

   Sammanfattning : For sequential decision-making problems with potentially catastrophic consequences appropriate risk assessment may be required. In contrast to traditional techniques for decision-making under uncertainty that aim to maximise performance in expectation, we chose to focus on other properties of the probability distribution.

4. 3. Railway Safety - Risks and Economics

   Författare :Johan Bäckman; KTH; []
   Nyckelord :Railway safety; Risk analysis; Statistical analysis; CBA; Economics; Willingness To Pay; Risk criteria;

   Sammanfattning : Safety analysis is a process involving several techniques.The purpose of this thesis is to test and develop methodssuitable for the safety analysis of railway risks and railwaysafety measures. Safety analysis is a process comprisingproblem identification, risk estimation, valuation of safetyand economic analysis. LÄS MER

5. 4. Disturbed sleep and emotion : a developmental perspective

   Författare :Nanette S. Danielsson; Steven J Linton; Markus Jansson-Fröjmark; Børge Sivertsen; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sleep disturbance; emotion dysregulation; catastrophic worry; sleep-onset; partial sleep deprivation; neuroticism; depressive symptoms; Psykologi; Psychology;

   Sammanfattning : Sleep disturbances are not only defining features, but also diagnostic criteria for most psychiatric disorders. Recently, researchers have proposed a theoretic role for sleep disturbances in emotion dysregulation, subsequently linking neurobiological processes and psychopathology. LÄS MER

7. 5. Interrogating Atherosclerotic Plaque Biology Through Responses to Cardiovascular Risk Management and Imaging

   Författare :Elin Good; Ebo de Muinck; Petter Dyverfeldt; Tiny Jaarsma; Dick Wågsäter; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Atherosclerosis causes more deaths than any other disease worldwide, and the cause of death is most commonly a rupture of a vulnerable atherosclerotic plaque, resulting in a thrombotic event in the heart or brain. The major risk factors for plaque progression are well known, but all the mechanisms that drive atherosclerotic plaques towards catastrophic events are not yet fully elucidated. LÄS MER
