  1. 1. Is it safe? safety factor reasoning in policy-making under uncertainty

    University dissertation from Stockholm : KTH

    Author : Jonas Clausen Mork; KTH.; [2006]
    Keywords : HUMANIORA; HUMANITIES; safety factor; uncertainty factor; uncertainty function; uncertainty; rationality; policy; decision; science; risk; HUMANITIES and RELIGION History and philosophy subjects Philosophy subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Filosofiämnen;

    Abstract : This thesis examines the practice of using safety factors in decision-making under uncertainty, in particular in the areas of toxicology and civil engineering. The aim is to expose and clarify some of the philosophical issues surrounding the practice. READ MORE

  2. 2. Economic Implications of Corporate Social Responsibility and Responsible Investments

    University dissertation from Göteborg : University of Gothenburg

    Author : Cristiana Manescu; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Corporate Social Responsibility; Strategic CSR; Socially Responsible Investments; Sustainability; Firm Profitability; Stock Returns; Statistical Learning Techniques; Variable Selection; Smooth Splines; Regression Trees; Data Envelopment Analysis; Difference-GMM; Risk-Factor Test; Market Efficiency; Control Functions Approach.;

    Abstract : Paper 1 (with Catalin Starica): This study conducts an in-depth analysis of the association between a unique ten-dimensional set of Corporate Social Responsibility (CSR) scores and firm profitability, as measured by Return on Assets (ROA). We find that non-linear (semi or non-parametric) regression methods bring important improvements in explaining profitability relative to a classical linear approach. READ MORE

  3. 3. Fire safety design of road tunnels

    University dissertation from Lund University. Department of Fire Safety Engineering

    Author : Jonatan Gehandler; [2020-02-06]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE

  4. 4. Fatigue Assessment and Extreme Response Prediction of Ship Structures

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Wengang Mao; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fatigue assessment; extreme response; rainflow; narrow-band approximation; Laplace Moving Average model; transformed Gaussian; zero up-crossing response frequency; significant wave height; safety index; upcrossing spectrum; long term cumulative distribution function; ship routing.;

    Abstract : In this thesis, a simplified narrow-band approximation model is proposed to estimate fatigue damage of ship structures, and an efficient method for extreme response predictions is also developed using upcrossing spectrums of ship responses.The proposed fatigue model includes two main parameters, significant stress range hs and zero upcrossing frequency fz.

  5. 5. Dealing with uncertainty

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jonas Clausen Mork; KTH.; [2012]
    Keywords : HUMANIORA; HUMANITIES; safety factor; safety margin; uncertainty factor; uncertainty function; uncertainty; information; risk; risk assessment; risk management; epistemology; science; reasoning;

    Abstract : Uncertainty is, it seems, more or less constantly present in our lives. Even so, grasping the concept philosophically is far from trivial. In this doctoral thesis, uncertainty and its conceptual companion information are studied. Axiomatic analyses are provided and numerical measures suggested. READ MORE
