   Författare :Annika Skoogh; Marie Louise Hall-Lord; Carina Bååth; Ann-Kristin Sandin-Bojö; Kristina Schildmeijer; Karlstads universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adverse events; construct validity; healthcare professionals’ perceptions; interviews; intrapartum care; questionnaire; patient safety; patient safety culture; record review; reliability; teamwork; women giving birth; Nursing Science; Omvårdnad;

   Sammanfattning : The overall aim of the thesis was to describe adverse events for women with planned vaginal births and healthcare professionals’ perceptions of patient safety. Further, to test the reliability and validity of a teamwork questionnaire and to investigate patient safety culture and teamwork among healthcare professionals in intrapartum care. LÄS MER

3. 2. Effective Spatial Mapping for Coupled Code Analysis of Thermal–Hydraulics/Neutron–Kinetics of Boiling Water Reactors

   Författare :Joanna Peltonen; Weimin Ma; Maria Avramova; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boiling Water Reactor; RELAP5; TRACE; PARCS; Coupled TH NK analysis; Spatial Mapping; Turbine Trip; Feedwater Transient; Control Rod Drop; Reactor Stability; Hierarchical Clustering; kokvattenreaktor; reaktoranalys; RELAP5; TRACE; PARCS; TH NK analys; turbin tripp; matarvatten transient; fallande styrstav; reaktor stabilitet; hierarkisk klustringsmetodik; SRA - Energy; SRA - Energi;

   Sammanfattning : Analyses of nuclear reactor safety have increasingly required coupling of full three dimensional neutron kinetics (NK) core models with system transient thermal–hydraulics (TH) codes.  In order to produce results within a reasonable computing time, the coupled codes use two different spatial description of the reactor core.

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

   Författare :Jonas Clausen Mork; John Cantwell; Stig Andur Pedersen; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; safety factor; uncertainty factor; uncertainty function; uncertainty; rationality; policy; decision; science; risk; Philosophy subjects; Filosofiämnen;

   Sammanfattning : 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. LÄS MER

5. 4. Fire safety design of road tunnels

   Författare :Jonatan Gehandler; Avdelningen för Brandteknik; []
   Nyckelord :HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

   Sammanfattning : 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. LÄS MER

7. 5. Dealing with uncertainty

   Författare :Jonas Clausen Mork; John Cantwell; Till Grüne-Yanoff; Terje Aven; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; safety factor; safety margin; uncertainty factor; uncertainty function; uncertainty; information; risk; risk assessment; risk management; epistemology; science; reasoning;

   Sammanfattning : 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. LÄS MER
