  1. 11. Creditor Rights and Innovation : Evidence from China

    Författare :Qing Xia; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In this paper I investigate if and how strengthening creditor rights enables firms to engage in more innovation activities, using the enactment of a new property law in China as a natural experiment. By using a newly constructed measure of land unavailability, I find that firms in cities where construction is more constrained by geography substitute short-term debt with long-term debt, hold less internal cash, invest more on intangible assets and eventually generate more patents after the enactment of the law.

  5. 14. Mechanical Properties of Semi-Solid Al Castings : Role of Stirring

    Författare :Qing Zhang; Anders E.W. Jarfors; Stefan Jonsson; Jens Bergström; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; aluminium alloys; stirring; segregation; porosity; oxides; ductility; fatigue performance;

    Sammanfattning : Semi-solid metal (SSM) casting has been widely used in automotive industries to reduce the weight. In RheoMetalTM process which is one of the variations of SSM, the slurry fabrication can be finished within 30 second and can the slurry making process can be integrated into a high pressure die casting (HPDC) route without significant adjustments, making the process a promising alternative for industrial application.
