  1. 1. Frame dynamics and stakeholders in risk governance

    Författare :Beatrice Bengtsson; Research Policy Institute (RPI); []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GMOs; framing; EU; stakeholders; expertise; governance rationalities; policy; feed; boundary framing; frame extension; intertextuality; food chain; participation; EFSA; DG SANCO; risk assessment; risk management; threshold; risks.;

    Sammanfattning : The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs.

  3. 2. Dynamics of Coinfection : Complexity and Implications

    Författare :Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. LÄS MER

  4. 3. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers

    Författare :Johan Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transverse modes; noise; modeling; Semiconductor laser; dynamics; vertical-cavity surface-emitting laser;

    Sammanfattning : In this work, a comprehensive dynamic model has been developed for simulating a novel semiconductor laser type, referred to as the Vertical-Cavity Surface-Emitting Laser (VCSEL). The high-speed behavior was simulated and compared to experiments, where excellent agreement was found. LÄS MER

  5. 4. Bringing System Dynamics into Action Research

    Författare :Paul Holmström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; process consultation; Operations Research; simulation; action research; modelling; System Dynamics; healthcare;

    Sammanfattning : System Dynamics simulation is a computer-aided approach to policy analysis and design, often carried out by external experts in simulation. System Dynamics is particularly useful in complicated and complex situations, such as healthcare. However, research has shown that few models in healthcare are implemented. LÄS MER

  7. 5. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics

    Författare :Florian Burmeister; Eckart Rühl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Photoelectron spectroscopy; HCl; DCl; Dissociation dynamics; Born-Oppenheimer approximation; Synchrotron radiation; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.
