Economic growth and the transition from traditional to modern energy in Sweden

We examine the role of substitution from traditional to modern energy carriers and of differential rates of innovation in the use of each of these in Sweden from 1850 to 1950. We use a simple growth model with a nested CES production function and exogenous factor augmenting technological change and carry out a growth accounting decomposition based on the econometric results. Energy and energy

Fragmentation

The global governance architecture on climate change has been increasingly marked by institutional fragmentation. A growing diversity of institutions seeks to address dangerous climate change today, including international organizations, club-like forums, multi-stakeholder partnerships, regulated and voluntary markets, sub-national efforts and non-state actor initiatives. After taking stock of thi

Choice blindness and trust in the virtual world

Choice blindness is the experimental finding that people may miss changes to the outcome of their actions. This effect has been demonstrated in decision tasks concerning attractiveness of faces, as well as smell and taste of different consumer products. But so far, choice blindness experiments have only been done in the “physical” world, using real objects like photographs. Here we extend this res

Train evacuation inside a tunnel: An interview study with senior citizens and people with disabilities

An interview study was performed in order to reveal some of the problems associated with evacuation of a train inside a tunnel for senior citizens and people with disabilities, and to identify possible technical installations that would aid their evacuation. A total of 19 people took part in the study, in which it was demonstrated that senior citizens and people with disabilities require either a

Att (åter)skapa "det normala". Bröstoperationer och brännskador i plastikkirurgisk praktik

Vad är "det normala"? Vad ingår i detta mångtydiga och inflytelserika begrepp, och hur skapas och återskapas det? Den moderna plastikkirurgin ger oss möjlighet att modifiera våra kroppar - bota skador och rätta till brister. Denna möjlighet kan också uppfattas som ett krav och ett hot, och medicinens dubbla roll som frälsare och förtryckare går som en röd tråd genom boken. Var går gränsen mellan

Measurement of the Generalized Forward Spin Polarizabilities of the Neutron

The generalized forward spin polarizabilities 0 and LT of the neutron have been extracted for the first time in a Q2 range from 0.1 to 0.9 GeV2. Since 0 is sensitive to nucleon resonances and LT is insensitive to the resonance, it is expected that the pair of forward spin polarizabilities should provide benchmark tests of the current understanding of the chiral dynamics of QCD. The new results on

Improving oxygen concentration control in activated sludge process with estimation of respiration and scheduling control

The paper presents an efficient and simple model-based method of on-line estimation of respiration from the current values of dissolved oxygen concentration and airflow signals. Fast estimation of respiration is important because respiration appears as the most important disturbance signal in the control of dissolved oxygen concentration, and could therefore be used for improving control efficienc
