Les trois premiers textes portent sur les phénomènes sensibles: sur le nombre des sens (Brentano), le traitement des phénomènes sensibles dans la phénoménologie de Husserl (Stumpf) et l'héritage du phénoménisme de Mach dans le néokantisme de Natorp (Palette). Les contributions suivantes s’inscrivent dans le cadre du débat contemporain sur la conscience phénoménale. Elles discutent la pertinence et les difficultés d’une approche phénoménologique du monde (Uriah Kriegel), de l’intentionnalité (Dan Zahavi) et du mental (Dewalque & Seron). [less ▲]

This paper offers a critical discussion of the so-called argument from the transparency of experience. We recall of the argument against the historical background of phenomenal anti-dualism (Natorp, Wundt, Russell) and identify three difficulties of it. Eventually, we propose an alternative view, which we call phenomenological dualism. On the proposed view, there is a sense in which our mental states may be said to appear to us, hence there is a sense to say that there are mental phenomena. [less ▲]

L’évaluation est une pratique enseignante qui poursuit diverses fins : certifier la maitrise de savoirs ou l’acquisition de compétences, autoriser l’élève à passer dans la classe supérieure, l’inciter à travailler, et bien d’autres. Dès que l’on est un tant soit peu en contact avec le monde scolaire, on a l’impression que les enseignants francophones belges passent un temps considérable à évaluer. Mais force est de constater qu’on sait peu de choses sur les pratiques évaluatives des enseignants de langues étrangères du secondaire supérieur. Cette recherche exploratoire vise à déterminer le temps que les enseignants de langues étrangères allouent à l’enseignement et à l’évaluation. Pour ce faire, les prescrits de langues étrangères des deux réseaux principaux (l’enseignement officiel et l’enseignement libre) ont confrontés aux pratiques de huit enseignants. A cause d’une configuration disciplinaire axée sur quatre compétences communicationnelles (la compréhension à l’audition et à la lecture, l’expression écrite, et l’expression ou l’interaction orale) que les prescrits obligent à certifier plusieurs fois annuellement, les enseignants passent plus d’un cours sur quatre à évaluer leurs élèves. Cependant, ils ne ressentent pas cette pression du certificatif de prime abord : ce n’est qu’après avoir été confrontés à leur ratio personnel d’évaluation/enseignement qu’ils se rendent compte du caractère chronophage de l’évaluation dans leurs cours. En outre, ils déclarent tous regretter de ne pas pouvoir certifier leurs élèves sur leur maitrise des savoirs lexicogrammaticaux, pratiques que les prescrits interdisent. Passer près d’un cours sur quatre à évaluer les élèves sur des compétences qu’ils sont censés maitriser au moment de l’évaluation semble excessif et redondant. Une solution consisterait à réduire le nombre de compétences à certifier annuellement. On pourrait par exemple privilégier les compétences passives (compréhensions à l’audition et à la lecture) en début d’apprentissage, et les compétences actives (expressions écrite et orale) en fin d’apprentissage.

Neuston includes animals and plants inhabiting the surface layer of the water column. The neustonic area is an accumulation zone for bacteria, organic molecules but also terrestrial debris. The surface layer is also the air/water exchange region. Therefore, neustonic organisms are directly exposed to several constraints such as wind stress and turbulence. The present study aims to characterize the zooneuston in terms of abundance and biodiversity and to evaluate the impacts of wind stress on neustonic abundance. Zooneustonic and zooplanktonic (depth of 5 meters) samples were collected twice a month between 30th August 2011 and 10th July 2012 in Calvi Bay, Corsica. Zooneustonic biodiversity was high and, notably, twenty-eight copepod genera were identified. Among these copepods, several organisms, belonging to the Pontellidae family, were much more frequent in neuston than in underlying plankton and their abundance depended on wind direction. Taxon-specific trends in seasonal abundance variation were present. For example, individuals of the Acantharia Lithoptera spp. were found in summer whereas the Pontellidae Anomalocera patersoni appeared in winter. Overall, our data provide a first step towards a better knowledge of neuston community structure in the Mediterranean Sea. [less ▲]

RNAi therapeutics are promising therapeutic tools that have sparked the interest of many researchers. In an effort to provide a safe alternative to PEI, we have designed a series of new guanidinium and/or morpholino functionalized biocompatible and biodegradable polycarbonate vectors. The impact of different functions (morpholino-, guanidinium-, hydrophobic groups), of the architecture (linear homopolymer to dumbbell-shape) and of the molecular weight of these copolymers on their capacity to form polyplexes and to decrease the expression of two epigenetic regulators of gene expression, HDAC7 and HDAC5 was evaluated. The use of one of these polymers combining morpholine and guanidine functions at the ratio >1 and hydrophobic trimethylene carbonate groups showed a significant decrease of mRNA and protein level in HeLa cells, similar to PEI. These results highlight the potential of polycarbonate vectors for future in vivo application as an anti-cancer therapy. [less ▲]

The supporting cells of the hearing organ are characterized by the presence of an abundant cytoskeleton which is mainly composed of microtubules. These supporting cells have also been shown to contain a minor mammalian tubulin, the β5-tubulin, recently reported as a biomarker of cell proliferation. It was shown that a β-tubulin isoform can specify the microtubule architecture, as seen with the expression of the Moth β2 tubulin in the Drosophila testes which imposes the 16-protofilament (16pf) structure on the corresponding subset of Drosophila microtubules. Moreover, supporting cell microtubules are formed by 15pf instead of the canonical 13, a unique fact among vertebrates. Such a protofilament configuration has been observed in C. elegans’ neurons which are responsible for the mechanosensory sense of touch. It was also shown that these 15pf microtubules were essential to the proper functioning of these neurons. To determine the role of this particular tubulin in the auditory organ and its possible involvement in the formation of the unusual 15pf microtubules of supporting cells, we studied the spatiotemporal localization of β5-tubulin during development in rats from embryonic day 18 until P25 (25th postnatal day). Then we examined the fine structure of microtubules at the transmission electron microscope level (TEM). Our results showed that β5-tubulin, contrary to other β-tubulins, had a unique distribution in the cochlea. This β-tubulin appeared at a postnatal stage, before the opening of the Corti’s tunnel and is restricted to supporting cells, especially in pillar and Deiters’ cells. Our TEM study further indicated that these cells were composed by 13pf microtubules at P2, but by 15pf microtubules at P25. In conclusion, the architecture and composition of microtubules present in the supporting cells change during development of the Corti organ. Further experiments are now required to determine if these changes are related to the appearance of β5-tubulin. [less ▲]

OBJECTIVES: The objective of this study was to propose an optimal treatment regimen of meropenem in critically ill patients with severe nosocomial pneumonia. PATIENTS AND METHODS: Among 55 patients in intensive care treated with 1 g of meropenem every 8 h for severe nosocomial pneumonia, 30 were assigned to intermittent infusion (II; over 0.5 h) and 25 to extended infusion (EI; over 3 h) groups. Based on plasma and epithelial lining fluid (ELF) concentrations determined at steady-state, pharmacokinetic modelling and Monte Carlo simulations were undertaken to assess the probability of attaining drug concentrations above the MIC for 40%-100% of the time between doses (%T > 1-fold and 4-fold MIC), for 1 or 2 g administered by either method. RESULTS: Penetration ratio, measured by the ELF/plasma ratio of AUCs, was statistically higher in the EI group than in the II group (mean ± SEM: 0.29 ± 0.030 versus 0.20 ± 0.033, P = 0.047). Considering a maximum susceptibility breakpoint of 2 mg/L, all dosages and modes of infusions achieved 40%-100% T > 1-fold MIC in plasma, but none did so in ELF, and only the 2 g dose over EI achieved 40%-100% T > 4-fold MIC in plasma. CONCLUSIONS: The optimum regimen to treat severe nosocomial pneumonia was 2 g of meropenem infused over 3 h every 8 h. This regimen achieved the highest pharmacodynamic targets both in plasma and in ELF. [less ▲]

What can immigrants do for non-migrant relatives in their home country who need healthcare they cannot afford? To answer this question, we first examine four existing methods that can be found in the existing literature: mobility, remittances, workers’ health insurance and diasporic health insurance. In the second part of the paper, we discuss an innovative strategy called “transnational health insurance” (THI). These insurance schemes are set up by immigrants in cooperation with a multitude of actors including health insurance companies in destination countries and healthcare providers in countries origin. THIs offer health coverage to non-migrant relatives in the home country based on a premium paid directly by immigrants to the insurance company in their country of residence. Analyzing the creation and implementation of Belgian-Congolese THIs, we discuss the strengths and weaknesses of these schemes in responding to the needs of both immigrants and their non-migrant relatives. The article concludes with a discussion on the specificities of THIs as hybrid forms of remittances. [less ▲]

The history of decolonization is inseparable from that of Western interests in the newly independent states. The special case of Franco-Belgian Relations offers a rich and unexplored perspective. Ostracized by the United Nations in the summer of 1960 in the context of the Congolese crisis, Belgium has, however, been able to count on the support of France, itself immobilized by the Algerian case. Based on unpublished archives, it seems instructive to study the evolution of the Franco-Belgian relations, in terms of Central African Affairs from 1961 to 1965. France, the overseas influence policy is a fundamental factor, she will devote as much energy to develop and defend its interests in Congo former Belgian (on which she claimed in Brussels its preemptive right, dating back to 1884, spring 1960) as former territories of the French Community? What are the forms, the protagonists and channels (formal and informal) of this influence; how is she fits the postcolonial context and she has an impact on Franco-Belgian relations ? [less ▲]

This paper presents a five-spring model capable of predicting the complete pre- and post-peak shear behaviour of deep beams. The model stems from a two-parameter kinematic theory (2PKT) for the shear strength and displacement capacity of deep beams under single curvature. Four of the springs of the model represent the shear resistance mechanisms of the beam, while the fifth spring models the flexural behaviour. The model predicts not only the load–displacement response, but also the deformation patterns of the beam and how these patterns change with increasing load. Validation studies are performed by using 28 tests from the literature, showing excellent results. The model is used to interpret the tests and to draw conclusions about the behaviour of deep beams. It is shown that shear strength variations of up to 60 % between nominally identical specimens can be caused by variations in the path of the critical shear cracks. It is also demonstrated that loss of bond of large reinforcing bars increases the shear capacity of deep beams. Finally, the five-spring model is shown to predict the post-peak shear behaviour effectively, which is important for the analysis of structures under extreme loading. [less ▲]

The degree of phosphorus saturation (DPS) represents the ratio of sorbed phosphorus (P) to the P sorption capacity (PSC) of soils. In some countries, DPS is used to evaluate the risk of P loss and surface water eutrophication. This study investigated DPS measurement and prediction in neutral loamy soils fromWallonia, Belgium. A total of 57 agricultural topsoil samples subject to diverse P management were evaluated. No satisfactory relationship could be found between PSC determined by a one-point short-term isotherm in the laboratory and the sum of aluminium and iron extracted by oxalate (Alox +Feox). The equation PSC=a Alox +b pHw appeared to be more appropriate for estimating PSC in the soils studied. These soils had a near-neutral pH, and P fixation processes linked to the presence of calcium ions or carbonates were important. Comparisons of DPS with soil-test P and water-extracted P suggested that DPS could be a useful agronomic and/or environmental indicator. Our results also showed that DPS values between 20 and 30% corresponded to the agronomic optimum of soil P content. Consequently, DPS may be used as an indicator of P status in neutral soils, provided that the PSC assessment is adapted to the local soil characteristics. [less ▲]
