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)

In lieu of an abstract, here is a brief excerpt of the content:Three Moments in the Crisis of Exemplarity: Boccaccio-Petrarch, Montaigne, and CervantesKarlheinz StierleIn his recent book History as Topic Peter von Moos denies that there was any crisis for the exemplum in the Renaissance. 1 He strongly argues against my essay on “History as exemplum,” where I pointed out that in Montaigne, as earlier in Boccaccio, the pragmatic form of exemplum is put into question. 2 My main interest in (...) this essay, however, was not to mark a break between Middle Ages and Renaissance but to understand the way in which the correlation between sententia and exemplum was transformed into a more complex relation between moral reflection and particular case. Undoubtedly, since Valerius Maximus and his Factorum et dictorum memorabilium libri, there has always been, as in John of Salisbury’s Policratius, the possibility of questioning the exemplary truth of the exemplum by opposing it to a never-ending wealth of counter-examples. This, however, never puts into question the idea of exemplarity itself. The validity of the exemplum as a rhetorical form of narration that tends towards its own conceptual or ideological structure has an anthropological basis. It presupposes that over time, there is more analogy in human experience than diversity, or that in all situations of civil and political life the pole of equality is stronger than that of difference.Boccaccio’s novella is precisely the narrative form that puts this anthropological basis into question. Each novella in the Decameron is essentially a [End Page 581] particular variant of a more general conceptual scheme. The stress of narration, however, is not on the scheme itself but on the autonomy of the variant. Basically the novella is a form of rewriting in the mode of retelling, thus bringing an elementary narration to higher complexity. 3 Each of the “vari casi,” mostly of love-affairs, is a confrontation of exemplarity and contingency. It is the power of contingency or fortuna that brings forth the specific particularity of each novella. The art of the writer Boccaccio, whose primary fiction is oral story-telling, consists in giving aesthetic evidence to this particularity. Reading, not listening, is the form of reception that corresponds to this structure. That Boccaccio adds the other title “Il Prencipe Galeotto” to the Decameron is an allusion to Dante’s Divine Commedy where in the famous episode of Paolo and Francesca (Inf. V), Galeotto becomes the personification of the allegory of reading and its seduction.Contingency, or, in Boccaccio’s own medieval terms, fortuna, is the real poet of the novella. That is why the most important scenes of the novellas are those where the power of contingency comes to light: at the sea and in the city. The particular shape of novella, which results from a balance between contingency and significant configuration, emerges from contingency itself. Its configuration is a particular case of contingency, one that by its immanent structural elegance is aesthetically gratifying. It nevertheless leaves open the question whether there might not be a power of a superior kind behind contingency. Because there is an ambiguity between contingency and sense, the exemplary status of each story is, ironically, placed in question. Contingency overcomes exemplarity; however, it never triumphs definitely. The impact on the exemplum by contingency not only gives to each narrative case its difference or even autonomy, it also opens up a new temporal dimension. The exemplum seems to move in an essential time where all time-aspects are controlled and functionalized by a dominating conceptual structure. In the novella time becomes a primary structure. “Or avviene che” is the narrative formula for this new quality of narrative time, becoming a time of disruption and instability where things and situations may change in a moment for the better or for the worse.I would like to illustrate the structure of the Boccaccian novella by at least one exemplary case. Almost in the middle of the book—which means in the middle of its temporal space of ten days—we find the novella of Federigo degli Alberighi, considered to be one of Boccaccio’s finest (V, 9). Federigo, in a world of merchants and trade, is the perfect nobleman who ruins himself by his... (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)

In order to understand why analytic aesthetics has lost a lot of its former intellectual stature it is necessary to combine historical reconstruction with systematic consideration. In the middle of the twentieth century analytic philosophers came to the conclusion that essentialist theories of the “nature” of art are no longer tenable. As a consequence they felt compelled to move to the meta-level of conceptual analysis. Then they tried to show how a purely classificatory concept of art is used. The presupposition, (...) however, that there actually is such a concept can only appear plausible at first sight. Upon closer inspection it turns out to be utterly misguided. (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)

Interdisciplinarity and the Development of Knowledge. The author is engaged in the question how to explain the development of scientific meanings of facts which does not coincide with producing them rather with processes of the scientists' public communication. So long as the facts are adjustable to the conventional theories of those discipline which the researcher belongs to this connection does not reveal perfectly clear. More instructive is a consideration of so-called 'anomalies'. The author demonstrates with an example of the history (...) of science that researchers in case of new phenomena use to borrow concepts from other disciplines for resolving the interpretative problems. It emerges a loose net-work of concepts. In this way the researchers are producing a disciplinary mixed public at the same time. This process is seen as an important phase of the development of new theories and, complementary, new disciplines. (shrink)
