La conception du "dialogue" de Mikhaïl Bakhtine et ses sources sociologiques (l'exemple des "Problèmes de l'oeuvre de Dostoïevski" [1929])

Résumé: L'article porte sur la conception du « dialogue » de Mikhaïl Bakhtine dans laquelle s'articulent deux groupes d'idées : 1) la notion de « dialogue » en tant que forme de l'interaction verbale interindividuelle (l'échange des répliques) et 2) la notion de « dialogisme » comme principe qui prévoit un rapport particulier entre le « Moi » (le « Je ») et l'« Autrui ». Son but consiste à 1) analyser ces notions au sens de Bakhtine, en s'appuyant sur le texte russe des Problèmes de l'oeuvre de Dostoïevski (1929) ; et à 2) montrer leurs sources sociologiques (principalement russes). Il y est également question de la notion de « polyphonie » introduite par Bakhtine pour caractériser la particularité de la construction des romans de Dostoïevski et d'une facette des réflexions bakhtiniennes sur le rôle de la « polyphonie » chez Dostoïevski, contenues dans le texte russe de 1929, abandonnées dans la version de 1963 et, de ce fait, méconnues des chercheurs francophones n'ayant accès qu'à la traduction des Problèmes de la poétique de Dostoïevski (1963). This paper examines the conception of "dialogue" elaborated by Mikhaïl Bakhtin in which are articulated two groups of ideas : 1) the notion of "dialogue" as a form of verbal interindividual interaction (an exchange of speech) and 2) the notion of "dialogism" as a principle which implies a relation between the "Me" (the "I") and the "Other". Its aim is 1) to analyse these notions in the sens of Bakhtin, on the base of russian text of Problems of Dostoyevsky's Art (1929) and 2) to show their sociological (mainly russian) origins. The paper also deals with the notion of "polyphony" introduced by Bakhtin to characterize the particularity of Dostoyevsky's method of constructing novels and with one facet of bakhtinian reflections (expounded in the text of 1929, omitted in the version of 1963, thereby unknown by francophone researchers who have access only to the translation of Problems of Dostoyevsky's Poetics (1963)) on the role of "polyphony" in Dostoyevsky's works.

Iowa Flood Mitigation Board Annual Report, 2014

The Iowa Flood Mitigation Program is created within Code of Iowa, Chapter 418. The Program seeks to provide funds for flood mitigation projects that otherwise would not be funded. The Flood Mitigation Board is responsible for the implementation Code of Iowa Chapter 418. The membership of the Board is comprised of four voting public members appointed by the Governor, five voting members representing state agencies, and four non-voting ex-officio members of the legislature.

Sources d'exposition aux phtalates dans une unité de soins néonatals [Phthalate exposure in the neonatal intensive care unit].

There are growing concerns on long-term health consequences, notably on fertility rates, of plasticizers such as phthalates. While di(2-ethylhexyl)phthalate (DEHP) is currently used in several medical devices, newborns in the neonatal intensive care unit are both more exposed and more vulnerable to DEHP. The objectives of this study were to identify, count, and describe possible sources of DEHP in a neonatal care unit. Our method consisted in the listing and the inspection of the information on packaging, complemented by contact with manufacturers when necessary. According to the results, 6% of all products and 10% of plastic products contained some DEHP; 71% of these involved respiratory support devices. A vast majority of the items showed no information on the content of DEHP. Further research is needed, particularly to determine the effects of such an early exposure and to study and develop safer alternatives.

Recommendations and Funding Options to Mitigate Flood Risk, November 2009

Iowa legislation required the state’s Water Resources Coordinating Council (WRCC) to submit policy and make recommendations that promote a watershed management approach to reduce the adverse impact of future flooding on this state’s residents, businesses, communities, and soil and water quality.

Modeling morphogen gradient formation from arbitrary realistically shaped sources.

Much of the analytical modeling of morphogen profiles is based on simplistic scenarios, where the source is abstracted to be point-like and fixed in time, and where only the steady state solution of the morphogen gradient in one dimension is considered. Here we develop a general formalism allowing to model diffusive gradient formation from an arbitrary source. This mathematical framework, based on the Green's function method, applies to various diffusion problems. In this paper, we illustrate our theory with the explicit example of the Bicoid gradient establishment in Drosophila embryos. The gradient formation arises by protein translation from a mRNA distribution followed by morphogen diffusion with linear degradation. We investigate quantitatively the influence of spatial extension and time evolution of the source on the morphogen profile. For different biologically meaningful cases, we obtain explicit analytical expressions for both the steady state and time-dependent 1D problems. We show that extended sources, whether of finite size or normally distributed, give rise to more realistic gradients compared to a single point-source at the origin. Furthermore, the steady state solutions are fully compatible with a decreasing exponential behavior of the profile. We also consider the case of a dynamic source (e.g. bicoid mRNA diffusion) for which a protein profile similar to the ones obtained from static sources can be achieved.

Montrer les minarets pour imposer une Suisse «chrétienne» : les sources évangéliques d'une initiative populaire

Cette contribution revient sur l'initiative anti-minarets acceptée par le peuple suisse en 2009, retraçant la confection de certains de ses arguments dès le début des années 2000, par l'Union démocratique fédérale, un petit parti d'inspiration évangélique. L'analyse ressaisit la façon dont la médiatisation la monstration des musulmans a joué en défaveur de leur reconnaissance publique. L'élucidation du concept de visibilité se veut attentive à certaines formes d'instrumentalisation de la publicité par des acteurs (des politiciens de la droite religieuse) qui en forcent d'autres (les musulmans de Suisse) à apparaître dans l'espace public, afin de susciter une controverse et promouvoir leur programme identitaire, qui vise à inscrire le christianisme dans les institutions nationales, de façon à inverser le processus de sécularisation.
