    Emergence of Foresight Activities in Swedish Government Authorities

    This paper discusses and aims to explain the emergence of foresight activities in Swedish government authorities, including environmental scanning and analysis, futures studies and other activities trying to detect and analyse change in the surroundings of the organisation. To explain the growing importance of foresight activities we must consider the increasing administrative authority given to public authorities in recent years, and the development of information technology that has given new technological opportunities to conduct foresight. Furthermore, structural (and institutional) changes - such as globalisation and the development of the EU - created a need and incentives for more foresight activities.Foresight; Futures studies; Swedish government authorities; Public authorities; Information; Information society; Globalisation; Internationalisation; Technological change; EU

    Competition Policy and the Swedish Model

    The aim of this paper is to present some findings from a study on the development of competition policy in Sweden since 1945. The comprehensive questions are about the view on knowledge in competition policy, the trust to the Swedish model, the change of the model and what has replaced it, and the attitudes to competition and co-operation in politics, authorities and interest groups. The study is basically built on government bills and directives to committees, committee reports, and comments on the later from authorities and interest groups. Typical signs of the Swedish model were a consensus and co-operative attitude towards interest conflict, with institutional arrangements aimed for negotiations and pragmatism. This was also typical for competition policy. During the 1990s we find a change to an EU-model. It meant a transition to a more legalistic and theoretic view on competition. When it comes to attitudes they changed successively in the direction of favouring competition before co-operation. The change was however radical when it comes to politicians and competition authorities. Not least the later came to argue for an “antitrust” view on competition. However, business interests were sceptical to the new competition law copying the EU-model.competition policy; Swedish model

    An explicit calculation of the Ronkin function

    Full text link
    We calculate the second order derivatives of the Ronkin function in the case of an affine linear polynomial in three variables and give an expression of them in terms of complete elliptic integrals and hypergeometric functions. This gives a semi-explicit expression of the associated Monge-Amp\`ere measure, the Ronkin measure.Comment: 22 pages, 13 figure

    Heating from free-free absorption and the mass-loss rate of the progenitor stars to supernovae

    Full text link
    An accurate determination of the mass-loss rate of the progenitor stars to core-collapse supernovae is often limited by uncertainties pertaining to various model assumptions. It is shown that under conditions when the temperature of the circumstellar medium is set by heating due to free-free absorption, observations of the accompanying free-free optical depth allow a direct determination of the mass-loss rate from observed quantities in a rather model independent way. The temperature is determined self-consistently, which results in a characteristic time dependence of the free-free optical depth. This can be used to distinguish free-free heating from other heating mechanisms. Since the importance of free-free heating is quite model dependent, this also makes possible several consistency checks of the deduced mass-loss rate. It is argued that the free-free absorption observed in SN 1993J is consistent with heating from free-free absorption. The deduced mass-loss rate of the progenitor star is, approximately, 10^(-5) solar masses per year for a wind velocity of 10 km/s.Comment: 15 pages, 3 figures; accepted for publication in Ap
