The doctor-patient relationship has evolved to respect “the autonomy and patients’ rights”. One of the cornerstones in such autonomy is the opportunity for patients to draw living wills, also known as advance directives. However, information about AD available to patients remains scarce largely due to the lack of involvement of General practitioners for several reasons. The aim of our study was to evaluate current general practitioner residents’ behavior concerning their role in informing their patients about AD. We built a French (...) nationwide survey from GPR class of 2012 to 2014. Two thousand three hundred ten residents completed our survey. 89.8% declared their willingness to offer patients the opportunity of writing AD. When asked about the usefulness of AD, 73.6% of residents responded that these are a suitable help for patients, but 19.7% considered that AD are essentially geared towards frail patients. Among residents who want to inform patients about AD, 14.7% wanted to involve all patients. Only 20.5% thought that elderly people should be systematically informed about AD. When the question involves other frail people in various disease areas, information seems relevant for 60.1% of GPR considering patient with cancer or malignant hematologic disease and for 56.2% about patients affected by neurodegenerative disease. When considering the routine use of AD, 20.5% of GPR would take them into account only if they are in agreement with the patient’s decision. The results of the survey indicate that GPR would rather choose to decide who should be informed about AD, and when to take AD into account for ethical concerns. (shrink)

Blaise Pascal est le penseur radical des limites et des contradictions de l'homme, ni ange ni bête. Contrairement à ce qu'en prétend l'orgueil de toute une modernité, la raison ne peut pas tout ; mais contrairement au désespoir du fanatisme, la raison n'est pas sans force. Jusqu'où alors peut-elle s'exercer? Pour Pascal, la philosophie ne saurait faire l'économie de la question de Dieu, Elle doit donc croiser la théologie. Mais comment vont se nouer l'ordre de l'esprit et celui de la (...) charité? Pascal produit ainsi une analyse critique de la philosophie comme telle, de ses capacités et de ses limites, que le présent ouvrage se donne pour tâche de clarifier. Que peut la philosophie? Mais qui décide de ce qu'elle peut, et surtout de ce qu'elle ne peut pas? Comment s'établissent alors ses rapports avec la théologie? Ce que Pascal nous invite ainsi à penser, c'est toujours à la fois la misère et la grandeur de la philosophie. (shrink)

Philosophers of science have long neglected applied science as one of the proper objects of their study. This neglect is an unrecognized legacy of positivism and its preoccupation with scientific theory. The rationalists and historicists among philosophers of science of the last twenty-five years recognize other disadvantages of this preoccupation with theory. But because they exclude engineering and applied science from consideration, they fail to see the power of pragmatism to transform the issues of their own debates. Hacking makes all (...) these points in his book, as he argues for a scientific realism discovered through understanding the activity of experimentalists in science. (shrink)

How is language acquired when infants are exposed to multiple language input from birth and when adults are required to learn a second language after early childhood? How do adult bilinguals comprehend and produce words and sentences when their two languages are potentially always active and in competition with one another? What are the neural mechanisms that underlie proficient bilingualism? What are the general consequences of bilingualism for cognition and for language and thought? This handbook will be essential reading for (...) cognitive psychologists, linguists, applied linguists, and educators who wish to better understand the cognitive basis of bilingualism and the logic of experimental and formal approaches to language science.

We represent consensus formation processes based on iterated opinion pooling as a dynamic approach to common knowledge of posteriors :1236–1239, 1976; Geanakoplos and Polemarchakis in J Econ Theory 28:192–200, 1982). We thus provide a concrete and plausible Bayesian rationalization of consensus through iterated pooling. The link clarifies the conditions under which iterated pooling can be rationalized from a Bayesian perspective, and offers an understanding of iterated pooling in terms of higher-order beliefs.

Controversies in economics often fizzle out unresolved. One reason is that, despite their professed empiricism, economists find it hard to agree on the interpretation of the relevant empirical evidence. In this paper I will present an example of a controversial issue first raised and then solved by recourse to laboratory experimentation. A major theme of this paper, then, concerns the methodological advantages of controlled experiments. The second theme is the nature of experimental artefacts and of the methods devised to detect (...) them. Recent studies of experimental science have stressed that experimenters are often merely concerned about determining whether a certain phenomeonon exists or not, or whether, when, and where it can be produced, without necessarily engaging in proving or disproving any theoretical explanation of the phenomenon itself. In this paper I shall be concerned mainly with such a case, and focus on the example of preference reversals, a phenomenon whose existence was until quite recently denied by the majority of economists. Their favourite strategy consisted in trying to explain the phenomenon away as an artefact of the experimental techniques used to observe it. By controlled experimentation, as we shall see, such an interpretation has been discredited, and now preference reversals are generally accepted as real. The problem of distinguishing an artefact from a real phenomenon is related to methodological issues traditionally discussed by philosophers of science, such as the theory-ladenness of observation and Duhem's problem. Part of this paper is devoted to clarifying these two philosophical problems, and to arguing that only the latter is relevant to the case in hand. The solutions to Duhem's problem devised by economic experimentalists will be presented and discussed. I shall show that they belong in two broad categories: independent tests of new predictions derived from the competing hypotheses at stake, and ‘no- miracle arguments’ from different experimental techniques delivering converging results despite their being theoretically independent.

Dawid, DeGroot and Mortera showed, a quarter century ago, that any agent who regards a fellow agent as a peer--in particular, defers to the fellow agent's prior credences in the same way that she defers to her own--and updates by split-the-difference is prone to diachronic incoherence. On the other hand one may show that there are special scenarios in which Bayesian updating approximates difference splitting, so it remains an important question whether it remains a viable response to ``generic" peer update. (...) We look at arguments by two teams of philosophers against difference splitting. (shrink)

This paper introduces a logic to reason about a well-known model of opinion dynamics in socialnetworks initially developed by Morris DeGroot as well as Keith Lehrer and Carl Wagner. The proposed logic is an extension of Lukasiewicz' famous fuzzy logic with additional equational expressivity, modal operators, machinery from hybrid logic, and dynamic modalities. The model of opinion dynamics in social networks is simple enough to be easily grasped, but still complex enough to have interesting mathematical properties and applications. Thus, developing (...) a logic to reason about this particular model serves as a paradigmatic example of how logic can be useful in social network analysis. (shrink)

This research investigates the impact of corporate tax strategies on consumers’ corporate social responsibility perceptions, willingness to pay, and attitude toward the firm in two laboratory experiments in the United States and Germany. Using the Becker–DeGroot–Marschak incentive-compatible mechanism, which avoids a social desirability bias found in prior research, our results indicate only a minor indirect effect of corporate tax strategies on WTP by way of the mediator CSR perceptions. However, we find a strong effect on attitude toward the firm again (...) mostly mediated by CSR perceptions. In contrast to German consumers, U.S. consumers’ CSR perceptions of tax avoidance are independent of whether a strategy is likely accepted by the tax authorities. Overall, we conclude that CSR perceptions are highly relevant when it comes to consumer responses to tax avoidance. (shrink)

Recluses, ermites ou engagées dans le monde, les saintes travesties sont nombreuses jusqu’à la fin du Moyen Âge. Ayant valeur de transgression et/ou d’initiation, le travestissement permet à Thècle, Pélagie, Marguerite, Marine ou Eugénie de redéfinir non seulement la notion de virginité mais d’affirmer une sainteté au nom d’une intégrité qui dérange les catégories sexuées et renverse les notions de genre. D’autres, comme Galla, Paula ou Wilgeforte, délivrent de l’antagonisme des sexes. Et toutes, jusqu’à Jeanne d’Arc, bouleversent la destinée (...) des femmes en perturbant l’ordre temporel des hommes. Ainsi apparaît la conquête d’un nouveau corps à travers la mission chrétienne et l’expérience mystique, qui déjoue la nature de femme et les vertus masculines. (shrink)

The purpose of the work reported here was to investigate the role of problem comparison and, specifically, analogical comparison in the induction of problem categories. This work was motivated by two factors. First, it is well-documented that experts and novices represent problems in very different ways and that solution success often depends on producing expert-like problem representations (DeGroot, 1965; Duncker, 1945; Chi, Feltovich, & Glaser, 1981; Hardiman, Dufresne, & Mestre, 1989; Novick, 1988; Schoenfeld & Herrmann, 1982; Silver, 1979, 1981). Second, (...) the problem representations produced by experts and novices appear to reflect differences in the way the two groups organize their knowledge bases. Although both groups appear to represent their problem-solving knowledge in terms of problem classes, or categories, expert categories tend to be defined in terms of deep structural features, whereas novice categories tend to be defined in terms of surface features (Adelson, 1981; Chase & Simon, 1973; Chi et al., 1981; Schoenfeld &. Herrmann, 1982; Silver, 1979, 1981). Because of this differential organization, experts are more likely than novices to retrieve solution-relevant information from their categories when constructing problem representations. (shrink)

This article investigates how subjects determine minimum selling prices for lotteries. We design an experiment where subjects have at every moment an incentive to state their minimum selling price and to adjust the price, if they believe that the price that they stated initially was not optimal. We observe frequent and sizeable price adjustments. We find that random pricing models cannot explain the observed price patterns. We show that earlier prices contain information about future price adjustments. We propose a model (...) of Stochastic Pricing that offers an intuitive explanation for these price adjustment patterns. (shrink)
