La recherche doctorale en relation avec cet article vise à préciser les liens entre la compétitivité territoriale, l’immobilier d’entreprise et le sujet des parcs d’activités économiques. Le terrain empirique investigué est celui de la Wallonie, une région où la disponibilité en terrains à vocation économique est considérée comme un levier essentiel du redéploiement économique. L’objectif de cet article est de rendre compte des grands questionnements ayant conduit à structurer notre projet de thèse. Afin de répondre à cet objectif, nous avons organisé l’article en trois chapitres. Le premier vise à présenter le contexte investigué. Nous y dressons un bref état des lieux quant à la problématique des parcs d’activités en Wallonie. Au deuxième chapitre, nous synthétisons notre état de l’art, en précisant comment la compétitivité territoriale s’articule au domaine de l’immobilier d’entreprise. Enfin, en troisième partie, nous présentons les principales étapes de notre projet doctoral, dont l’objectif opérationnel est d’aider les autorités wallonnes à mieux préciser leur stratégie en matière de terrains à vocation économique.

Les zones d'activité économique constituent, en Wallonie, un des leviers majeurs à disposition du Gouvernement pour favoriser le développement économique. Leur implantation suscite toutefois de nombreux débats au sein des élus locaux. Ces débats sont notamment alimentés par la perception que ces zones génèrent des recettes fiscales très limitées pour les communes. Cette contribution propose une analyse et une mesure des facteurs qui influencent ces recettes et, par conséquent, les choix locaux en matière d'affectation de l'espace. [less ▲]

The author starts with a discussion about two notions appearing into the Rorschach test: the perception and the apperception. By this way, it is suggest ways for a phenomenological study of the Rorschach test. These proposals are consistent with those of the Comprehensive System (Proposed by John E. Exner). Then the author proposes a protocol analyzing of a patient with a perverse psychological functioning. In one hand, the result obtained by the Form Quality (FQ) is detailed in particular regarding to the status of unusual perceptions. According to the Comprehensive System proposed by J.E. Exner, a significant proportion of responses "u" (46% for this protocol) indicates that the person is not influenced by any social request or any expectation and some of his behaviors could ignore or avoid any question about social convention. From an other point of view, when analyzing these data, an adaptive dimension for these unusual perceptions is identified. The pervert perceives the stimuli that "really exists" according to him not everyone can perceive it. This advantage allows a better adaptation to the environment and the ability to change this environment. The manipulation (a particular skill that is most of the time attributed to the perverse person) is probably a consequence of having an original perception of reality. It is also discussed the interpretation of the "anatomical content" in connection with this adaptive hypothesis. In addition, the author also discusses a particular answer of the protocol: the answer "shoes" that presents a specific perceptual characteristic. [less ▲]

Le diagnostic precoce de l’insufissance renale aigue (IRA) est necessaire et devrait se faire au stade de lesion renale avant meme la degradation du debit de filtration glomerulaire. Plusieurs biomarqueurs d’atteinte renale aigue sont actuellement a l’etude. Parmi ceux-ci, le Neutrophil Gelatinase Associated Lipocalin (NGAL) semble l’un des plus prometteurs et fait l’objet de nombreuses publications. La performance diagnostique de NGAL, dose dans le plasma ou les urines, pour le depistage de l’IRA depend de nombreux facteurs. Bien que les donnees experimentales recentes soient en faveur de l’utilisation preferentielle du dosage urinaire de NGAL, les donnees cliniques issues de nombreuses etudes ne permettent pas de trancher formellement sur la superiorite du dosage urinaire par rapport au dosage plasmatique pour le depistage des atteintes renales aigues. Il n’en reste pas moins que sur le plan analytique, les techniques de dosage du NGAL urinaire sont actuellement plus fiables que celles du dosage plasmatique. La performance diagnostique de NGAL dans un contexte d’IRA est maximale en chirurgie cardiaque pediatrique. Les resultats, chez l’adulte en postoperatoire de chirurgie cardiaque et dans d’autres situations (reanimation, urgences, transplantation), sont moins convaincants. Par ailleurs, il n’est actuellement pas possible d’extrapoler des etudes cliniques une valeur seuil discriminante unique de NGAL, aussi bien dans les urines que dans le plasma. D’autres etudes sont necessaires pour valider definitivement NGAL comme biomarqueur de l’atteinte renale aigue et en preciser les conditions d’utilisation en pratique clinique. [less ▲]

MALDI in-source decay (ISD) has been used for the top-down sequencing of proteins. The use of 1,5-diaminonapthalene (1,5-DAN) gave strong intensity of w ions, which are informative fragments and can be helpful for the distinction of the isobaric amino acids, Leu and Ile. Our data suggests that the w fragments are formed from z* radical fragment by unimolecular dissociation and high abundance of w ions in MALDI-ISD with 1,5-DAN can be understood as resulting from the low collision rate in the MALDI plume. The MALDI-ISD with 1,5-DAN could be a useful method for the top-down sequencing of proteins including discrimination of Leu and Ile near the C-terminal end. [less ▲]

Currency total return swaps (CTRS) are hybrid derivatives instruments that allow to simultaneously hedge against credit and currency risks. We develop a structural credit risk model to evaluate CTRS premia. Empirical test on a sample of 23,005 price observations from 59 underlying issuers yields an average percentage error of around 10%. This indicates that, beyond interest rate risk, firm-specific factors are major drivers of the variations in the valuation of these instruments. Regression analysis of residuals shows that exchange rate determinants account for up to 40% of model pricing errors — indicating that a currency risk premium affects the CTRS price significantly but only marginally, which confirms the prevalence of credit risk in the pricing of CTRS.

This study investigated the role of odorant cues used during host-habitat location by the generalist parasitoid, Nasonia vitripennis Walker. N vitripennis is a common parasitoid of Dipteran pupae found in association with decaying carrion. Behavioral assays were used to investigate the host-habitat searching behavior under different scenarios. First, we demonstrated N. vitripennis to be significantly attracted toward odorant cues associated with decaying meat. The biological activity of nine of the volatile molecules constituting the odor of decaying meat were tested on the searching behavior of parasitoid females through two complementary chemoecological approaches: electronantennography (EAG) and olfactometry bioassays. Butanoic acid and butan-1-ol elicited high olfactory responses, but no attraction was induced by these two chemicals. Behavioral assays showed that, among the VOCs tested, methyldisulfanylmethane (DMDS) was the only volatile chemical to induce attraction in N. vitripennis. [less ▲]

Depuis les travaux de Jean-Louis FOURNEL et Jean-Claude ZANCARINI, notamment, il est établi que les auteurs florentins qui vécurent à l’époque des guerres d’Italie identifièrent immédiatement la nouveauté et le caractère extraordinaire des faits qui bouleversèrent leur époque. Parmi ceux-ci, le célèbre Nicolas Machiavel mais aussi son ami et contemporain, Francesco Guicciardini, qui, si l’histoire littéraire ne lui a pas toujours fait la part belle, retrouve ces dernières années la place qui lui revient dans celle des idées. Auteur, historiographe mais aussi lieutenant des troupes pontificales lors de la Ligue de Cognac et, donc, acteur de l’histoire en train de se jouer, Francesco Guicciardini est en prise directe avec les événements ; dans sa volumineuse correspondance se mêlent petite et grande Histoire. Or, si le substantif et l’adjectif « contemporaneo » existent en italien depuis Dante au moins, Guicciardini n’en fait l’usage ni dans ses œuvres, ni dans ses lettres qui ne comptent aucune occurrence du terme. Partant de ce constat, je me propose, dans mon article, de relever et d’analyser le langage utilisé par Guicciardini pour nommer le moment auquel il vit, en cerner les contours et la façon dont celui-ci se distingue de ce qui précède pour former un moment à part : les expressions qui disent le présent (tempo presente/tempi presenti, questi tempi, medesimi tempi) et celles qui le caractérisent (conditione de' tempi, extraordinario, tempi strani) ou qui expriment le moyen de l’affronter (remedii conformi a’ tempi) seront, dès lors, au centre de mon attention.

While anchor heads are particularly useful in the case of large bars which require significant development lengths, the ACI code provides design guidance for bars #11 or smaller. This paper presents a test of a large deep beam reinforced with a single #18 headed bar. The behavior of the beam is evaluated in comparison to the behavior of a specimen with more conventional reinforcement of 6#8 headed bars, and to the behavior of a specimen with lap-spliced anchor hooks. Despite the extreme detailing of the specimen with a single #18 bar, the beam had the same strength as the specimen with 6#8 bars. The compressive stress in front of the anchor head reached about 1.5 times the compressive strength of the concrete and the stress in the #18 bar reached about 414 MPa (60 ksi) before the beam failed in shear along a diagonal crack away from the anchorage zone. Shear strength calculations according to Appendix A of the ACI code showed that the current strut-and-tie provisions can overestimate the shear strength of deep beams by as much as 23%. [less ▲]

There is a growing interest for vitamin D in the medical and scientific community as well as in the public medias as illustrated by a huge number of publications. Most experts claim that vitamin D deficiency/insufficiency is widespread with potential important public health consequences. It may seem surprising for many persons that a deficiency in a vitamin may be so frequent in countries where food is so diversified and easily available. In fact, vitamin D is not a vitamin stricto sensu as it is mainly synthesized in the skin under the action of UVB rays, while its food sources are scarce. Furthermore, UVB rays are absent during a marked part of the year at latitudes greater than 35-40°, while pollution and cloud cover reduce the number of UVB reaching the earth, and many factors such as age, skin pigmentation, covering clothes, sun creams reduce the capacity of the skin to synthesize vitamin D3. Vitamin D must be hydroxylated to form 1,25dihydroxyvitamin D (1,25OH2D), the active metabolite. As 1,25OH2D is released into the bloodstream and binds to a receptor present in several distant tissues, it may be considered as a hormone, vitamin D being thus a pre-prohormone. In the present article, we review briefly the metabolism and various effects of vitamin D as well as the vitamin D assays and vitamin D treatments. We define vitamin D deficiency/insufficiency considering [less ▲]

We consider the question of finding deep cuts from a model with two rows of the type PI = {(x,s) ∈ Z2 ×Rn+ : x = f +Rs}. To do that, we show how to reduce the complexity of setting up the polar of conv(PI ) from a quadratic number of integer hull computations to a linear number of integer hull computations. Furthermore, we present an algorithm that avoids computing all integer hulls. A polynomial running time is not guaranteed but computational results show that the algorithm runs quickly in practice.

Abstract This study aims to validate our method for measuring accuracy in a melodic context. We analysed the popular song “Happy Birthday” sung by 63 occasional and 14 professional singers thanks to AudioSculpt and OpenMusic (Ircam, Paris, France). In terms of evaluation of the pitch interval deviation, we replicated the profile of occasional singers described in the literature (the slower the performance, the more accurate it is). Our results also confirm that the professional singers sing more accurately than occasional singers but not when a Western operatic singing technique is involved. These results support the relevance of our method for analysing vocal accuracy of occasional and professional singers and led us to discuss adaptations to be implemented for analysing the accuracy of operatic voices.

This paper proposes two methods to speed up the demanding time-domain simulations of large power system models. First, the sparse linear system to solve at each Newton iteration is decomposed according to its bordered block diagonal structure, in order to solve only those parts that need to be solved, and update only sub-matrices of the Jacobian that need to be updated. This brings computational savings without degradation of accuracy. Next, the Jacobian structure is further exploited to localize the system response, i.e. involve only the components identified as active, with an acceptable and controllable decrease in accuracy. The accuracy and computational savings are assessed on a large-scale test system. [less ▲]

Dans les diverses réformes conçues et implémentées en vue de moderniser l’administration, l’accent est mis sur les marchés avec un focus particulier sur les citoyens désormais clients (Korunka et al., 2007 ; Thomas, 2012). Alors que les approches initiales du NPM se centraient sur l’efficience, l’applicabilité et la pertinence de techniques managériales importées du secteur privé dans les organisations publiques (Ferlie et al., 1996), les réformes plus récentes tendent à inclure d’autres objectifs tels que la gestion de la qualité, la transparence et le centrage client (Meier & O’Toole, 2007 ; Lapsley, 2008). Du Gay (1996), pour sa part, affirme que le NPM est un projet identitaire, dans la mesure où il vise à redéfinir la main d’œuvre (en termes de profils et compétences recherchées, ciblant la figure du travailleur-entrepreneur en lieu et place du fonctionnaire). Bon nombre d’études interrogent également les paradoxes et les tensions intrinsèques du modèle NPM (Lynn, 1998; Aucoin, 1990; Hood, 2000 ; Goldfish & Wallis, 2010), les difficultés liées à sa mise en œuvre (Mathiasen, 1999 ; Dunleavy et al., 2006 ; Jones & Cole, 2009) ou à l’évaluation de ses outputs concrets pour l’administration (Pollitt, 1993; Hodge, 1999). De façon générale, la littérature met en lumière les effets que ces réformes ont produit sur les différentes facettes de l’administration : ses modes de fonctionnement et ses structures (Gualmini, 2008), son management, ses stratégie et pratiques de GRH (Pichault, 2007), ses missions et son identité organisationnelle (Horton, 2006) mais aussi sur l’ethos (Maesschalk, 2004 ; Fortier, 2010) et la motivation des fonctionnaires (Vandenabeele et Hondeghem, 2007), entre autres éléments. Plusieurs auteurs mentionnent les débats et questionnements identitaires qui se produisent lorsque l’organisation fait face à des situations de bouleversement profond (Albert et Whetten, 1985 ; Dutton et al., 1994 ; Alvesson et Empson, 2008). Dans un processus de réforme, l’organisation se remet en question et s’interroge sur ce qu’elle est, ce qu’elle devient, ce qu’elle veut être, propulsant l’identité organisationnelle au premier plan des préoccupations (Skalen, 2004 ; Meyer & Hammerschmid, 2006). Dans un contexte où l’identité organisationnelle est en proie à tel bouleversement, comment ses membres en font-ils l’expérience ? Ce questionnement, à la base de cet article, se pose en termes d’identification organisationnelle, unissant dans une même équation deux termes centraux : l’identité organisationnelle et les perceptions qu’ont les membres du contexte en évolution. La question que nous adressons est la suivante : dans un contexte d’organisation publique en mutation, quelles sont les dynamiques identitaires à l’oeuvre en regard de la perception des évolutions du contexte des individus ? A partir de l'analyse de la réforme Copernic (introduction du NPM dans l'administration fédérale belge) réalisée en 2005-2006, nous avons élaboré de manière inductive une typologie des logiques et profils identitaires, issue de l’analyse d’entretiens qualitatifs (Rondeaux, 2007, 2008, 2010). Sur base de celle-ci, nous avons mené une enquête par questionnaires auprès d’une administration régionale belge, engagée dans un processus de modernisation, en vue de vérifier l’existence et la pertinence de cette typologie, au moyen d’une démarche quantitative. Réalisée en 2010, cette enquête illustre en particulier trois aspects : 1. les représentations associées au travail au sein de l’administration en regard de son évolution, et le degré d’identification à l’institution dans ce contexte ; 2. la perception de la modernisation et le rôle de la hiérarchie dans cette perspective ; 3. les identités représentées au sein de l’institution (logiques institutionnalisée et alternatives, profils en congruence ou en dissonance). Nous montrons notamment que la majorité des positions est marquée par la dissonance, principalement relative à la valeur ajoutée de la modernisation et à sa mise en œuvre concrète. [less ▲]

In the context of multistage stochastic optimization problems, we propose a hybrid strategy for generalizing to nonlinear decision rules, using machine learning, a finite data set of constrained vector-valued recourse decisions optimized using scenario-tree techniques from multistage stochastic programming. The decision rules are based on a statistical model inferred from a given scenario-tree solution and are selected by out-of-sample simulation given the true problem. Because the learned rules depend on the given scenario tree, we repeat the procedure for a large number of randomly generated scenario trees and then select the best solution (policy) found for the true problem. The scheme leads to an ex post selection of the scenario tree itself. Numerical tests evaluate the dependence of the approach on the machine learning aspects and show cases where one can obtain near-optimal solutions, starting with a “weak” scenario-tree generator that randomizes the branching structure of the trees.

El objetivo de este artículo es interrogar la incertidumbre que envuelve la gestión de territorios amazónicos. De hecho, en cada etapa de los programas de explotación de recursos naturales se reavivan controversias que obligan a rexaminar las formas de producción de conocimientos, las formas de contactar y las formas de manejar los territorios y sus poblaciones humanas y no-humanas. Yo me intereso particularmente a la situación de los pueblos dichos en “aislamiento voluntario”. ¿Cómo entrar en contacto sin reducirlos con nuestros virus occidentales o sin morir bajo sus lanzas? Pero también: ¿Cómo hacer hablar entidades que temporalmente no pueden, definitivamente no saben, o en ciertas ocasiones no quieren hacerlo? Estas son, entre otras, algunas preguntas que emergen en medio de la colonización interna de la Amazonía. He intentado comprender cómo se traduce este silencioso aislamiento a partir del análisis de la acción del Serviço de Proteção aos Índios (1910-1967) en Brasil, así como de los debates del Seminario Regional Pueblos indígenas en aislamiento voluntario y contacto inicial en la Amazonía y el Gran Chaco (Bolivia, 2006). He identificado dos controversias que dan testimonio de la complejidad del tema y nos obligan a reconsiderar la naturaleza de éstas poblaciones en la configuración de las áreas protegidas. [less ▲]

A model limited to motivation construct to explain the way from setting a vocational goal to its achievement cannot claim to give an account of how to overcome regulatory problems during goal striving. A model linking volition to motivation is needed. In particular, implementation intentions have been proved to be effective in helping the initiation of goal striving, shielding goal pursuit from unwelcome influences, and disengagement from not successful courses of action. It is proposed to extend the application of this volitional cognitive tool to career counselling. [less ▲]

Several factors, including fruit and vegetables intakes, have been shown to significantly influence the plasma concentrations of the two antioxidants vitamin C and β-carotene. Deficiency levels of 6 mg/L (34.2 μM) for vitamin C and of 0.22 mg/L (0.4 μM) for β-carotene have been suggested below which cardiovascular risk might be increased. The present study performed on 897 presumably healthy subjects aged 40–60 years aimed to examine how modifiable lifestyle factors may be related to vitamin C and/or β-carotene deficiency. Gender, smoking, lack of regular physical activity and of daily fruit consumption (≥2/day), and social status (in particular, unemployment) were found to be significant risk factors for vitamin C deficiency. For β-carotene deficiency, the same factors were identified except social status; moreover, overweight and OC use in women were also found to have a deleterious effect. For non exposed subjects, the probability of developing vitamin C deficiency was 4% in men and 2.4% in women. This probability increased to 66.3% for men and to 44.3% for women (and even to 50.4% under OC use), when all risk factors were present. For β-carotene deficiency, the corresponding probabilities were equal to 29.7% in men and 13.7% in women (no risk factor present), and to 86.1% for men and 69.9% (91.6% for OC use) for women (all factors present), respectively.

The strength of thin-walled stainless steel columns has been investigated extensively over the past few years. In European standards, the concept of section classification for determining the cross-section capacity is used. In this system, for Class 4 cross-sections, the Effective Width Method (EWM) must be used to account for the effect of local buckling. Because of the complexity and limitations of this method, other methods have been developed, such as the Direct Strength Method (DSM) for cold-formed thin-walled profiles and the Continuous Strength Method (CSM), initially established for members made of nonlinear metallic materials. In the CSM, to take advantage of strain hardening, a deformation-based design approach employing a continuous relationship between the cross-sectional slenderness and the cross-sectional deformation capacity is used. To a large extent, the CSM yield accurate predictions, especially in the low slenderness range where the current DSM design procedures for members submitted to pure compression tends to produce conservative predictions, for materials with pronounced strain hardening such as stainless steel alloys. The present paper presents an extension of the traditional DSM which provides accurate design strength predictions in the low slenderness range for stainless steel thin-walled section columns failing by distortional, local and overall buckling. It contains practical information concerning the reference experimental data and draws conclusions about the justification of the proposed analytical formula. The paper is divided into three main parts: the description of the database, the establishment of the design model and a reliability analysis of the method. [less ▲]

Dopo una introduzione storica e storiografica sul significato dei culti regali ellenistici, l’intervento esamina alcuni dei nomi divini attribuiti ad Arsinoe II nelle fonti letterarie e documentarie, con l’eccezione dell’epiclesi esclusiva Philadelphos. Scopo della ricerca è 1) una valutazione delle strategie di inserimento della nuova dea nel pantheon tradizionale; 2) una riflessione sull’autoconsapevolezza degli antichi in relazione alla propria tradizione religiosa, per come essa si manifesta attraverso l’oculata manipolazione di un elemento essenziale nella definizione della divinità, qual è il nome divino. Un’Appendice elenca, in tre tabelle, tutte le denominazioni greche di Arsinoe II (esclusa Philadelphos), fornendo indicazioni sulla fonte, la sua collocazione spaziale e temporale e sulla divinità tradizionale di riferimento.

Flow velocity and sedimentation patterns were investigated experimentally and numerically in shallow rectangular reservoirs with different asymmetric locations of the inlet and outlet channels. Velocity fields were measured in the entire reservoir, both for clear water flow and with suspended sediments. Thickness of sediment deposits were mapped in the whole reservoir by means of a laser light method. In one of the studied geometric configurations, injection of suspended sediments led to a complete change in the observed flow field. Experimental results were compared with numerical simulations performed with the depth-averaged flow model WOLF 2D, using a depth-averaged k-e turbulence model. The simulations lead to accurate predictions of the velocity profiles and the change in flow pattern as a result of sediment deposits was successfully reproduced. [less ▲]

In the south-eastern part of the Katanga Province (Democratic Republic of the Congo), high concentrations of copper and cobalt are found in the soils of the well-known “Copper Belt”. Due to the dominant south-eastern winds, the metallurgic industry in Lubumbashi has been the source of spatially concentrated atmospheric deposits of non-ferrous metal particles and associated substances in a cone-shaped zone, situated north-west of the metal processing site. The existence of this zone has been evidenced using two different techniques: firstly, by means of landscape metric comparisons of the vegetation and bare soil patterns in two study areas, one inside the pollution cone and one outside; secondly, by means of the theory on city perception developed by Kevin Lynch. Higher fragmentation and lower vegetation presence were observed inside the pollution cone, reflecting the negative impact of atmospheric deposits. Those differences were higher for sites closer to the emission source. Lynch’s approach outlined the negative impact of diverse industrial plants on the perception by the local population. Six pollution districts and several contaminated paths, limits, nodes and polluting landmarks were identified. Citizens even recognize them as part of the collective image of the city. [less ▲]

Due to the rapid development of technology, larger data sets concerning activity travel behavior become available. These data sets often lack semantic interpretation. This implies that annotation in terms of activity type and transportation mode is necessary. This paper aims to infer activity types from GPS traces by developing a decision tree-based model. The model only considers activity start times and activity durations. Based on the decision tree classification, a probability distribution and a point prediction model were constructed. The probability matrix describes the probability of each activity type for each class (i.e. combination of activity start time and activity duration). In each class, the point prediction model selects the activity type that has the highest probability. Two types of data were collected in 2006 and 2007 in Flanders, Belgium, i.e. activity travel data and GPS data. The optimal classification tree constructed comprises 18 leaves. Consequently, 18 if-then rules were derived. An accuracy of 74% was achieved when training the tree. The accuracy of the model for the validation set, i.e. 72.5%, shows that overfitting is minimal. When applying the model to the test set, the accuracy was almost 76%. The models indicate the importance of time information in the semantic enrichment process. This study contributes to future data collection in that it enables researchers to directly infer activity types from activity start time and duration information obtained from GPS data. Because no location information is needed, this research can be easily and readily implemented to millions of individual agents. [less ▲]

Diet of harbor porpoises along the Dutch coast: a combined stable isotope and stomach contents approach

High stranding frequency of porpoises, Phocoena phocoena, along the Dutch coast since 2006 has led to increased interest in the ecology of porpoises in the North Sea. Stranded porpoises were collected along the Dutch coast (2006–2008) and their diet was assessed through stomach content and stable isotope analysis (d13C and d15N) of porpoise muscle and prey. Stable isotope analysis (SIAR) was used to estimate the con- tribution of prey species to the porpoises’ diet. This was compared to prey composi- tion from stomach contents, to analyze differences between long- and short-term diet. According to stomach contents, 90.5% of the diet consisted of gobies, whiting, lesser sandeel, herring, cod, and sprat. Stable isotope analysis revealed that 70-83% of the diet consisted of poor cod, mackerel, greater sandeel, lesser sandeel, sprat, and gobies, highlighting a higher importance of pelagic, schooling species in the porpoises’ diet compared to stomach contents. This could be due to prey distribution as well as differ- ences in behavior of porpoises and prey between the coastal zone and offshore waters. This study supports the need for multi-method approaches. Future ecological and fishery impact assessment studies and management decisions for porpoise conservation should acknowledge this difference between the long- and short-term diet. [less ▲]

Reproductive impacts of tributyltin (TBT) and triphenyltin (TPT) in the hermaphroditic freshwater gastropod Lymnaea stagnalis

Tributyltin (TBT) and triphenyltin (TPT) are emblematic endocrine disruptors, which have been mostly studied in gonochoric prosobranchs. Although both compounds can simultaneously occur in the environment, they have mainly been tested separately for their effects on snail reproduction. Because large discrepancies in experimental conditions occurred in these tests, the present study aimed at comparing the relative toxicity of TBT and TPT under similar laboratory conditions in the 0–600 ng Sn/L range. Tests were performed on the simultaneous hermaphrodite Lymnaea stagnalis, a freshwater snail in which effects of TPT were unknown. Survival, shell length and reproduction were monitored in a 21d semi-static test. Frequency of abnormal eggs was assessed as an additional endpoint. TPT hampered survival while TBT did not. Major effects on shell solidity and reproduction were observed for both compounds, reproductive outputs being more severely hampered by TBT than by TPT. Considering the frequency of abnormal eggs allowed increasing test sensitivity, since snail responses to TBT could be detected at concentrations as low as 19 ng Sn/L. However, the putative mode of action of the two compounds could not be deduced from the structure of the molecules or from the response of apical endpoints. Sensitivity of L. stagnalis to TBT and TPT was compared to the sensitivity of prosobranch molluscs with different habitats and different reproductive strategies. [less ▲]

Cet article concerne le concept de réflexion et son importance pour la philosophie de l’art et de la politique depuis la modernité kantienne. Il s’organise en trois temps. Il s’agira d’abord d’interroger le concept de réflexion à l’œuvre dans la Critique de la raison pure et d’apprécier son rapport au jugement réfléchissant esthétique qui fait le cœur de la première partie de la Critique de la faculté de juger. Dans un deuxième temps, on montrera, en suivant H. Arendt, à quelle type de lecture politique ce problème esthétique kantien a pu donner lieu ; d’autre part, avec cette fois A. Badiou, on signalera à quelle sorte de critique s’expose la lecture arendtienne. L’objectif est en général de montrer qu’il est possible d’allier les propositions esthétiques de Kant avec un concept radical – marxien plutôt qu’arendtien – de la politique. C’est pourquoi, dans un troisième temps, on s’attachera à quelques textes de J. Rancière : la critique qu’il oppose aux lectures de Kant proposées par Bourdieu et par Lyotard démontre en effet qu’une pensée de la politique d’inspiration kantienne bien plus radicale que celle de Arendt reste possible. Plus globalement, on montrera ici que l’histoire de la philosophie moderne (par exemple kantienne) ne peut être à elle-même sa propre fin : elle doit toujours être infléchie en direction des enjeux actuels qui sont ceux de la philosophie politique, et ceux de la politique tout court. Sauf à estimer que la tâche philosophique doit désormais s’identifier à celle du gardien de musée, ou du gardien du temple. [less ▲]

Ce long article montre notamment que le propos épistémologique de Foucault et d’Althusser impliquait la destruction du concept classique de sujet (conscience de soi originaire formatrice de l’objectivité) et imposait sa reconstruction en deux temps : en tant que constitué (assujettissement), en tant que constituant (subjectivation). Étudiant la postérité de ce dernier thème dans la philosophie politique française contemporaine, par exemple chez J. Rancière et A. Badiou, il tente de forger, au-delà de ces auteurs, mais tout près d’É. Balibar, un concept de la transformation socio-historique comme subjectivation politique, et articule ce concept en termes de négativité et de totalité, d’autonomie et de finitude. Celui-ci se résumerait finalement de l’idée d’une « épreuve politique de la finitude », non loin de Bataille ou de Blanchot, soit « l’expérience d’un passage au dehors témoignant de la frappe de l’impossible et de l’infini mais qui se sait, et qui dès lors se construit, en tant que finie ».
