    Player Heterogeneity and Empiricism in Schelling

    No full text
    The main thesis of this paper is that Schelling's empiricism is deeply grounded in the assumption of player heterogeneity. He peoples games with real individuals and consequently postulates that there are differences in roles or identities among them. The subjects populating Schelling's thought or real experiments do not suppose that other players follow identical or symmetrical rules of logical inference to make their choices. This hypothesis is decisive in shaping Schelling's inductive game theory, which is applied by means of a three-step procedure. First, players are defined by making their differentiating features explicit. Secondly, heterogeneous players are embedded in a real environment to play the game. Thirdly, the game solution is derived inductively. This interpretation helps to explain why little progress has been made overall in developing Schelling's insights

    How a Psychologist Informed Economics: The Case of Sidney Siegel

    No full text
    In the 1950s before Kahneman and Tversky showed how behavioral economics could bring economics and psychology into a unified framework, a social psychologist, Sidney Siegel, entered the realm of economics and laid the foundation of experimental economics. This paper gives an assessment of Siegel's effort to meld psychology and economics and shows that Siegel was not only a contributor to the methodology of experimental economics but also a pioneer of behavioral economics. Although his legacy was paramount in the work of the Nobel Prize winner Vernon Smith, Siegel endorsed a very different approach to making interdisciplinary research effective. (C) 2010 Elsevier B.V.

    Late asthmatic reactions due to larvae of Calliphora erythrocephala used as fishing bait

    Clinical characteristics of allergic asthma due to inhalation of insect antigens have been investigated very little. We describe two patients presenting with dyspnoea and wheezing several hours after exposure to larvae of Calliphora erythrocephala used as fishing bait. Both patients had a positive intradermal skin test and a high level of circulating IgE to the specific allergen. Bronchial challenge test with the whole larvae resulted in an isolated late response in one case, and in a dual response in the other, which were prevented by premedication with DSCG or beclometazone. The occurrence of late asthmatic reactions may render it difficult for the identification of insect antigens as the causal agent of extrinsic allergic asthma

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
