We relax the assumption that priors are common knowledge, in the standard model of games of incomplete information. We make the realistic assumption that the players are boundedly rational: they base their actions on finite-order belief hierarchies. When the different layers of beliefs are independent of each other, we can retain Harsányi's type-space, and we can define straightforward generalizations of Bayesian Nash Equilibrium and Rationalizability in our context. Since neither of these concepts is quite satisfactory, we propose a hybrid concept, (...) Mirage Equilibrium, providing us with a practical tool to work with inconsistent belief hierarchies. When the different layers of beliefs are correlated, we must enlarge the type-space to include the parametric beliefs. This presents us with the difficulty of the inherent openness of finite belief subspaces. Appealing to bounded rationality once more, we posit that the players believe that their opponent holds a belief hierarchy one layer shorter than they do and we provide alternative generalizations of BNE and Rationalizability. Finally, we show that, when beliefs are degenerate point beliefs, the definition of Mirage Equilibrium coincides with that of the generalized BNE. (shrink)

In this commentary I discuss the role of types of knowledge and conceptual structures in lexical representation, revealing the explanatory potential of frame-based knowledge. Although frame-based lexical semantics is not alien to the theoretical model outlined in Jackendoff's conceptual semantics, testing its relevance to the analysis of the lexical evidence presented in his book has been left out of consideration.

This commentary asks the reader to examine Pylyshyn's target article and the imagery debate at four levels of analysis – institutional, programmatic, empirical, and individual. It is proposed that the debate follows somewhat generic patterns of discourse at all four levels, but the discourse associated with one side of the debate may or may not be expressible and evaluated in terms of the other. The different sides of the debate might better serve cognitive science if they proceed as separate research (...) programs in their respective sub-disciplines. A more inclusive program could result, however, if the opposing approaches could somehow unite. (shrink)

Today, bioethics experts have an increasing role in public life. However, the question arises: what does bioethics expertise really mean? Can there be such a thing in our globalised world characterised by ethical pluralism? I will argue that bioethics as a discipline represents the transformation of ethics expertise from a hard to a soft form of it. Bioethics was born as a reaction to the growing awareness of ethical pluralism, and it denied the hard form of normative–prescriptive ethics expertise, particularly (...) in its medical ethics form. In contrast, the traditional medical ethics model, and pre-modern societies in general, believed in hard normative ethics expertise. From this followed the characteristic paternalism of traditional medical practice: if physicians were experts in moral matters as well, if they knew what the right course of action to choose was, then they had a right to benevolently force this course of action on their patients. The remnants of this doctrine, although rarely stated explicitly, still can often be seen in clinical practice. The whole bioethics movement can be seen as a radical denial of the doctrine of physician's hard expertise in moral matters. Bioethics, however, represents a type of soft ethics expertise. Hence follows the seeming paradox of bioethics expertise: bioethics is both a denial of ethics expertise as well as a type of ethics expertise. (shrink)

Examining the naturalist and normativist concepts of health and disease this article starts with analysing the view of C. Boorse. It rejects Boorse's account of health as species-typical functioning, giving a critique of his view based on evolutionary theory of contemporary biology. Then it gives a short overview of the normativist theories of health, which can be objectivist and subjectivist theories. Rejecting the objectivist theories as philosophically untenable, it turns to the subjectivist theories of Gert and Culver, and to the (...) view of Nordenfelt. These theories give quite a good subjectivist account of health and disease, but they do not pay enough attention to the notion of the environment, without which it is impossible to define health and disease. Starting with their definitions but introducing the notion of “reasonable social norms”, the article arrives at the following definition of health: The healthier a physical or mental characteristic, process, reaction is, the more it makes it possible for the individual to adapt to reasonable social norms without pain and suffering, and the longer, and happier a life it will be able to ensure him in that society.

The current use of citation-based metrics to evaluate the research output of individual researchers is highly discriminatory because they are uniformly applied to authors of single-author articles as well as contributors of multi-author papers. In the latter case, these quantitative measures are counted, as if each contributor were the single author of the full article. In this way, each and every contributor is assigned the full impact-factor score and all the citations that the article has received. This has a multiplication (...) effect on each contributor's citation-based evaluative metrics of multi-author articles, because the more contributors an article has, the more undeserved credit is assigned to each of them. In this paper, I argue that this unfair system could be made fairer by requesting the contributors of multi-author articles to describe the nature of their contribution, and to assign a numerical value to their degree of relative contribution. In this way, we could create a contribution-specific index of each contributor for each citation metric. This would be a strong disincentive against honorary authorship and publication cartels, because it would transform the current win-win strategy of accepting honorary authors in the byline into a zero-sum game for each contributor.

This paper invokes the conceptual framework of Bourdieu to analyse the mechanisms, which help to maintain inappropriate authorship practices and the functions these practices may serve. Bourdieu’s social theory with its emphasis on mechanisms of domination can be applied to the academic field, too, where competition is omnipresent, control mechanisms of authorship are loose, and the result of performance assessment can be a matter of symbolic life and death for the researchers. This results in a problem of game-theoretic nature, where (...) researchers’ behaviour will be determined more by the logic of competition, than by individual character or motives. From this follows that changing this practice requires institutionalized mechanisms, and change cannot be expected from simply appealing to researchers’ individual conscience. The article aims at showing that academic capital is translated into honorary authorship. With little control, undetected honorary authorship gives the appearance of possessing intellectual capital. In this way a dominant position is made to be seen as natural result of intellectual ability or scientific merit, which makes it more acceptable to those in dominated positions. The final conclusion of this paper is that undemocratic authorship decisions and authorship based performance assessment together are a form of symbolic violence. (shrink)

Das Aequivalenzprinzip wurde von Einstein erst 1907 in Worte gefasst. Er wendete sich 1912 brieflich an W. Wien mit der Bitte, den Unterschied der Schwingungsdauer eines Uranpendels und eines Bleipendels sowie die Proportionalität der trägen und schweren Massen eines Blei- und eines Urangewichts auszumessen, und zwar mit einer Drehwage. Der Brief macht es klar, dass Einstein bei der Aufstellung des Aequivalenzprinzips von dem Eötvös-Versuch nichts wusste, und als es ihm nötig schien, das Prinzip experimentell zu prüfen, hat er den (...) Versuch neuentdeckt.The principle of equivalence was first formulated by Einstein in 1907. In 1912 he turned by letter to W. Wien with the request to measure the difference between the periods of oscillation of pendulums made of uranium and lead, as well as the proportionality of inertial and gravitational masses of a uranium and a lead weight, respectively, namely with a torsion balance. The letter testifies that Einstein was not aware of the Eötvös experiment when he formulated the principle of equivalence and as soon as he needed an experimental test of it, he reinvented the experiment.

Bódog (Felix) Somló is the most reputable representative of Hungarian legal philosophy at the last turn of the century, whose ouevre greatly contributed to the establishment of the neo-Kantian legal philosophy, the dominant trend preaviling in Central Europe at the time, a development that eventually resulted in modernising the legal scholarship and theoretical thought in law in Hungary. Hungarian jurisprudence can be proud of the fact that Bódog Somló, besides Rudolf Stammler, Gustav Radbruch, Hans Kelsen and Alfred Verdross is regarded (...) as a great representative of European neo-Kantian philosophy of law.

We present a rational model of consumer choice, which can also serve as a behavioral model. The central construct is λ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\lambda $$\end{document}, the marginal utility of money, derived from the consumer’s rest-of-life problem. It provides a simple criterion for choosing a consumption bundle in a separable consumption problem. We derive a robust approximation of λ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\lambda $$\end{document} and show how to incorporate liquidity constraints, (...) indivisibilities, and adaptation to a changing environment. We find connections with numerous historical and recent constructs, both behavioral and neoclassical, and draw contrasts with standard partial equilibrium analysis. The result is a better grounded, more flexible, and more intuitive description of consumer choice. (shrink)
