Estimation and evaluation of individualized treatment rules have been studied extensively, but real-world treatment resource constraints have received limited attention in existing methods. We investigate a setting in which treatment is intervened upon based on covariates to optimize the mean counterfactual outcome under treatment cost constraints when the treatment cost is random. In a particularly interesting special case, an instrumental variable corresponding to encouragement to treatment is intervened upon with constraints on the proportion receiving treatment. For such settings, we first (...) develop a method to estimate optimal individualized treatment rules. We further construct an asymptotically efficient plug-in estimator of the corresponding average treatment effect relative to a given reference rule. (shrink)

This chapter stages an ongoing conversation between Arthur Danto and the author. In a series of encounters from 1985 till 2012 (in New York City and elsewhere) the problem of defining art is explored from different angles. Eventually, two kinds of definition are distinguished. On the one hand, a definition may aspire to identify peculiar characteristics of the things that are commonly regarded members of the noble class of artworks. On the other hand, a definition might also name criteria for (...) deciding whether an object may become a member of this class in the first place. Danto focused on the first task because he felt, quite rightly, that the second would require competences that philosophy does not dispose of. (shrink)

English summary: Heinz Ludeking belonged to the German philosophical movement that explored analytical esthetics. Ludekings analytical approach to art brought new light to the definition and concept of art. In particular, he created a connection between logical reflection and esthetic investigation. French description: Heinz Ludeking appartient a ce courant de la philosophie allemande qui a pris pour objet l'esthetique analytique, et qui est encore largement meconnu en France en depit de sa productivite conceptuelle. Dans cet ouvrage, l'auteur s'est efforce d'etablir (...) un bilan critique de la premiere philosophie analytique de l'art - celle des annees 50-60 -, c'est-a-dire des travaux qui ont precede les theories de Goodman et de Danto. L'approche analytique de Ludeking, volontiers caustique, peut etre devastatrice. Elle apporte neanmoins une lumiere nouvelle sur un probleme central, jamais veritablement resolu, celui de la definition de l'art et du concept d'art. L'une des qualites dominantes de cette analyse est d'etre parvenue a realiser une jonction exceptionnellement rigoureuse entre la reflexion logique et l'investigation proprement esthetique. (shrink)

Die Welt, in der wir leben, andert sich rasant. Doch nicht nur sie, sondern auch die Religionen, die Gottesvorstellungen. Nach christlicher Vorstellung ist Gott selbst in die Dynamik der Welt verstrickt. Gerade die Prozesstheologie macht Gott im Fluss der Zeit denkbar. Welches ware der Gott, den wir brauchen? Welche Konsequenzen haben mogliche Antworten fur Religion und Politik, Okonomie und Okologie, Gesellschaft und Kultur? Diesen Fragen geht der Band nach.
