Aureobasidium pullulans (souche Ach1-1) a montré une grande efficacité vis-à-vis de Penicillium expansum agent de la pourriture bleue des pommes en conservation. Le présent travail a été réalisé dans le cadre de l’analyse des mécanismes d’action qui sont les plus impliqués dans son activité antagoniste. Dans des essais in vivo sur pommes blessées, l’effet protecteur de la souche Ach1-1 vis-à-vis de P. expansum a été significativement affaibli par l’ajout dans les blessures de concentrations élevées en acides aminés. L’importance de la réduction étant dépendante de la concentration appliquée, a montré que la compétition pour les acides aminés joue un rôle important dans la suppression de P. expansum. Ce résultat a été appuyé par l’analyse biochimique de la cinétique de l’épuisement des acides aminés dans les blessures des pommes qui a dévoilé que ces composés et particulièrement la sérine, la glycine et l’acide glutamique sont mieux métabolisés par la souche antagoniste que par le pathogène. L’ajout en excès de ces trois acides aminés individuellement dans les blessures des pommes a fortement réduit l’efficacité de la souche Ach1-1 vis-à-vis de P. expansum. Ainsi, ces acides aminés semble être parmi les éléments les plus limitants dans le mécanisme de la compétition. Ces résultats indiquent que l’antagoniste A. pullulans souche Ach 1-1 exerce une activité fongistatique plus que fongicide vis-à-vis de P. expansum et agit par une compétition efficace pour les éléments nutritifs limitants des blessures des pommes et particulièrement les acides aminés sans affecter la viabilité du pathogène.

Malgré la richesse et la vision collective que peut amener une équipe pluridisciplinaire, la pratique de médecine générale reste le plus souvent centrée sur les soins en réponse à une demande du patient et relevant d’une dimension individuelle. Malgré une motivation importante, l’équipe du CSI de Tilleur a du constater que le manque de compétences internes et le manque chronique de temps des soignants limitaient fortement ses aspirations à faire évoluer le modèle de soins vers les objectifs de globalité de prise en charge et pour l’ensemble des patients. Il a été décidé d’internaliser les compétences jugées manquantes par l'engagement d'une personne non soignante, dont la fonction est de soutenir l’équipe pluridisciplinaire dans ses projets de soins, de santé communautaire et de promotion de la santé. L’apport méthodologique propre à la santé publique en fait le point d’ancrage entre la conception d’un projet et sa réalisation concrète dans la pratique quotidienne. Des modifications structurelles commencent à apparaître parmi les soignants et des exemples de prise en charge globale de certaines pathologies ou actions préventives sont observés. La promotion de la santé, tant au niveau individuel que collectif, trouve une nouvelle place au sein d’une équipe principalement dédiée aux soins. [less ▲]

Purpose -- The purpose of this paper is to gain a better understanding of the market timing skills displayed by hedge fund managers during the 2007-08 financial crisis. Design/methodology/approach -- The performance of a market timer can be measured through the Treynor and Mazuy (1966) model, provided the regression alpha is properly adjusted by using the cost of an option-based replicating portfolio, as shown by Hübner (2010). We adapt this approach to the case of multi-factor models with positive, negative or neutral betas. This new approach is applied on a sample of hedge funds whose managers are likely to exhibit market timing skills. We stick to funds that post weekly returns, and analyze three hedge funds strategies in particular: long-short equity, managed futures, and funds of hedge funds. We analyze a particular period during which the managers of these funds are likely to magnify their presumed skills, namely around the financial and banking crisis of 2008. Findings -- Some funds adopt a positive convexity as a response to the US market index, while others have a concave sensitivity to the returns of an emerging market index. Thus, we identify "positive", "mixed" and "negative" market timers. A number of signs indicate that only positive market timers manage to acquire options below their cost, and deliver economic significant performance, even in the midst of the financial crisis. Negative market timers, by contrast, behave as if they were forced to sell options without getting the associated premium. We interpret this behavior as a possible result of fire sales, leading them to liquidate positions under the pressure of redemption orders, and inducing negative performance adjusted for market timing. Research limitations/implications -- The adjustment for market timing opens up the way to numerous tests over longer periods, and in particular comparative studies of hedge fund returns using nonlinear risk factors versus exposures to quadratic returns. Originality/value -- The paper suggests that the convexity in returns that is generally associated with market timing can be attributed to three sources: timing skills, exposure to nonlinear risk factors, or liquidity pressures. We manage to identify the impact of the latter two effects in the context of hedge funds. [less ▲]

Background. Fetal liver disease is a rare antenatal disorder for which etiology is frequently unknown. Recently, congenital alloimmune hepatitis emerged as a major cause of antenatal liver disease. Its typical presentation can be as a severe neonatal liver failure with hepatic and extrahepatic iron overload, a clinical state called neonatal hemochromatosis. Methods. A pregnant woman was investigated for heterogeneous fetal hepatomegaly. Pregnancy was also complicated by fetal alloimmune thrombocytopenia. The newborn presented at birth with liver cirrhosis and mild liver dysfunction. Follow-up until 36 months showed progressive normalization of all liver parameters. All metabolic and infectious analyses were negative. Liver biopsy showed severe hepatitis with post-necrotic fibrosis and regenerative nodules. There was no iron overload. To search for immune injury, paraffine sections of the liver biopsy were stained with an antibody against the membrane attack complex (MAC, anti human c5b-9, Peter Whitington’s Lab, Children’s Memorial Hospital, Chicago, IL), the terminal complement cascade neoantigen occurring specifically in complement activation by the IgG-mediated classical pathway, and which is responsible for cell death. Results. Strong immunostaining against MAC-antigen was found in the liver of the patient, with 90% of target hepatocytes whereas in a control group of patients with other neonatal liver diseases, it was 10.8±12.5%. Because IgG in neonates originate only from the mother, it signs the alloimmune nature of the disease. Conclusion. For a long time, pathophysiology of neonatal hemochromatosis remained unsolved. Recently, it was elucidated as congenital alloimmune hepatitis. With this case, we expend the recognized clinical spectrum by showing that congenital alloimmune hepatitis can present as milder cases, without iron overload. It should be considered as a cause of unexplained neonatal liver disease, even in the absence of siderosis. Such diagnosis is of great importance regarding the necessity of immunotherapy in further pregnancies in order to avoid recurrence of alloimmune injury [less ▲]

The Treynor and Mazuy framework is a widely used return-based model of market timing, but existing corrections of the regression intercept can be manipulated through derivatives trading. We propose an adjustment based on Merton's option replication approach. The linear and quadratic coefficients of the regression are exploited to assess the cost of the replicating option that yields similar convexity for a passive portfolio. A similar reasoning applies for various timing patterns and in multi-factor models. Our empirical application shows that, unlike existing performance adjustment methods, the portfolio replication approach uncovers a positive link between the convexity and the performance of market timing funds.

L'écologie chimique est la branche de l'écologie qui s'intéresse au décriptage de ce mode de communication, dont le maitre d'œuvre est le système olfactif des insectes, où antennes et sensilles supportent toute la machinerie physiologique nécessaire à la perception des phéromones et coactones. Pour comprendre le language chimique employé par un insecte, de nombreux outils ont été développés, permettant (1) l'échantillonnage des molécules organiques produites par un insecte, (2) la séparation, la quantification et l'identification des différents constituants du mélange phéromonal,(3) l'étude de la perception par le système olfactif de l'insecte et (4) l'étude du comportement d'un individu mis en présence d'un potentiel bouquet phéromonal ou de l'un de ses constituants. De nombreuses phéromones et coactones ont déjà trouvé le chemin de la valorisation dans le domaine de la protection des cultures.

Cet article est consacré à la modélisation numérique non linéaire des colonnes en béton armé soumises à un incendie. Dans ce travail nous analysons des colonnes en béton armé chargées par des efforts de compression excentrés et soumises à un feu normalisé. Du fait que les poteaux ont un rôle extrêmement important dans une construction, la vérification de leur résistance au feu dans les conditions d’incendie est cruciale. L’analyse se divise en deux étapes. Dans la première étape nous procédons à l’étude thermique des colonnes. Nous en déduisons les températures en fonction du temps que nous utilisons dans la deuxième étape pour l’étude mécanique. Lors de cette dernière nous obtenons les variations de différents paramètres tels que le moment fléchissant, les contraintes, les déplacements et le module tangent [less ▲]

Le problème de la violence résume pour ainsi dire l’œuvre de Jean-Paul Sartre. Il circonscrit souvent, en tout cas, les critiques qu’on lui adresse et, de façon fondamentale, la manière même dont on la lit. L’objet de cette communication sera de reprendre ce problème chez le dernier Sartre, de 1957 à 1973, c’est-à-dire de Questions de méthode à L’Idiot de la famille, à partir d’une analyse serrée de certaines interventions de Sartre sur le terrain politique ou plutôt juridico-politique. Je m’appuierai en particulier sur trois sources : l’intervention de Sartre au procès Ben Saddok (1957), sa préface aux Maos en France (1970) et sa conférence « Justice et État » (1973). Je souhaite mettre en évidence le travail d’élucidation politique que Sartre déploie à cette époque dans le cadre judiciaire, qu’il s’agisse de justice d’État ou de justice populaire. Chez Sartre, ce travail d’élucidation est inséparablement philosophique et littéraire. Il passe ainsi, d’une part, par un usage spécifique de la phénoménologie, dont Sartre a donné le programme dans son Esquisse d’une théorie des émotions, en une référence explicite à l’ontologie fondamentale de Heidegger ; il passe, d’autre part, par une reprise critique (philosophique et politique) de certaines références littéraires, en particulier de Malraux et de Camus dans le premier texte cité. L’Idiot de la famille propose la synthèse de cet effort : de faire de l’émotion une méthode (et non pas simplement d’explorer méthodiquement les émotions) et d’imprimer une torsion politique à la pratique littéraire (et non pas simplement d’y renoncer). À cette double condition, il peut être utile aujourd’hui de chercher, dans la philosophie de Sartre, certains moyens d’une heuristique de la violence et certains outils d’intelligibilité de ce qui, en dernière analyse, renvoie à la question de la liberté, autrement dit encore aux déterminations les plus fondamentales du partage entre puissance et impuissance.

Je voudrais ici tester l’hypothèse suivante : si le champ d’étude de l’image populaire (familiale) s’est vu parfois négliger par les théoriciens, peut-être est-ce à cause de l’écart radical que la photographie spécialisée, et en particulier la photographie artistique, a voulu établir entre elle et la photographie dite « domestique ». Comment (c’est-à-dire par quels moyens, théoriques ou artistiques) une certaine pratique de la photographie s’est-elle aujourd’hui instituée comme un art à part entière ? Plutôt et surtout : comment la noble pratique de la photographie a-t-elle réussi à prendre ses distances avec la photographie commune, pourtant omniprésente, jusqu’à l’évacuer presque totalement des préoccupations scientifiques ? Car il faut bien voir le paradoxe qui sous-tend ce problème : comment est-on parvenu à assigner à l’image commune (pourtant franchement majoritaire) un rôle aussi périphérique ? La place occupée par la photographie domestique dans les théories de la photographie reste incertaine. Quand elle n’est pas purement et simplement évacuée, l’image commune peut soit être « utilisée » pour porter un sens auquel elle ne prétendait pas, soit être prise en compte pour se voir aussitôt réduite à un stéréotype ; son caractère esthétique est dévalué, son style réduit à un non-style. En tenant à distance la culture la plus populaire, on agrandit certainement le gouffre qui sépare le théoricien des expériences vécues (des expériences sensibles). [less ▲]

Performance evaluation presents two specific difficulties for social enterprises. At the one hand, it is complex to define what performance is, to measure the factors impacting performance through indicators, and to sum up the scores of all the indicators. At the other hand, performance evaluation should vary with the purpose of the evaluation and the type of organization. Thus the characteristics of an ideal performance evaluation tool for social enterprises should both reflect this complexity and be contingent. [less ▲]

Emerging concerns about competitiveness induce a growing number of firms to outsource their outbound transportation operations to third-party logistics providers. The resulting increase in the number of actors often leads to sub-optimal supply chain actions due to the antagonistic nature of the economic objectives of the partners. With the aim of determining possible deviations from the optimal system performance in such supply chains, this study analyzes the contractual relation between a retailer and a third-party logistics provider (carrier) using game theoretical approaches. The partners of the studied supply chain play a Stackelberg game in which the retailer is the leader and the carrier is the follower. The retailer faces an uncertain demand and needs to supply his store from his warehouse. he has the option of not meeting all the demand but must satisfy at least a minimum proportion of the fi nall demand. On the other hand, the carrier has to determine the number of trucks needed to satisfy this demand before uncertainty is resolved. Once demand is realized, if the reserved transportation capacity is insufficient, the carrier also has the possibility to requisition trucks at a higher price. We modelise the problem and propose a contract having two parameters : the quantity of transported items and the number of truck used. In our settings, the retailer is the one that submits the contract and the carrier decides if he accepts it or not. We compare this situation with a centralized model where a single decision maker takes all the decisions. [less ▲]

In a Model-Based Drug Development strategy, the first objective is to design studies such that the most reliable model estimates are obtained, in order to optimize the design of future studies and to take decisions based on predictions. The objectives of the work is to present from a theoretical and practical point of view how to perform trial predictions, as opposed to trial simulations, by integrating the uncertainty of the parameters. The difference between prediction and simulation is important in early development when limited data or prior information are available. Indeed ignoring the uncertainty of parameter estimates can lead to wrong decisions. First, will be provided methodology, derived from Bayesian statistics, to perform trial predictions from the parameter estimates and their uncertainty, when obtained with conventional frequentist population methods. Second, a practical implementation in R will be shown. This generalized prediction shell can cope with any kind of structural population models: Ordinary Differential Equation, single & multiple doses, infusion, etc... The proposed shell is also flexible to allow the testing of various scenarios and study designs, and therefore evaluate the predictive probability of success of different protocols. When joint models for efficacy and safety are established, the Prediction-based Clinical Utility Index (p-CUI) and its distribution can directly be obtained for more riskless decision making. Examples will be shown to highlight in early phases the differences existing between trial prediction and trial simulation. This approach is required to permit Model-Based Drug Development strategy, and impact successfully decision in early clinical phases. [less ▲]

The Design Space (DS) is defined as the set of factors settings (input conditions) that will provide results at least better than pre-defined acceptance limits. The proposed methodology aims at identifying a region in the space of factors that will likely provide satisfactory results during the future use of an analytical method or process in routine, through an optimization process. In a Bayesian framework, the responses are modelled using a multivariate multiple regression model allowing deriving their joint predictive posterior distribution. On the basis of this consequent distribution, a multi-criteria risk-based decision is taken with respect to the pre-defined acceptance limits. This aims to identify the DS. In this context, desirability methodologies are also applied to take the risk-based decision in a more flexible way. An example based on high-performance liquid chromatography illustrates the applicability of the methodology with highly correlated and constrained responses. [less ▲]

The LIMA index conveys the environmental interest and quality of the landscape formed by the Mediterranean benthos, ranging from 0 to -40 m, in numerical format. The LIMA index allows a comparison spatially and temporarily between sites. It is a comprehensive index which is easy to implement and is composed of two factors: a topographical description (classification of 15 typologies) and a biological description (the presence or absence of some thirty species or groups of structuring, remarkable and invasive species). The LIMA index has been validated in the Bay of Calvi (Corsica-France) where it varies between 0.31 and 0.79 on a scale of 0.00 to 1.00. [less ▲]

A 3D high-order RANS solver in conservative variables has been developed, based on a discontinuous Galerkin/Symmetric Interior Penalty discretisation. The turbulence model is the well-known one-equation Spalart-Allmaras model. It is shown that in order to stabilise the discretization scheme, it is necessary to adapt the transpose penalty term, which introduces an explicit dependency of the continuity equation on the turbulent viscosity.

Social Networking Sites (SNS) provide a new platform for consumer/brand interaction on the Internet. On SNS, firms have the opportunity to create and manage a “brand page” in order to interact with SNS members. Brand pages allow interaction between the members of the page, as well as interaction between the members and the brand, namely brand tribalism and brand relationship. This paper investigates the functioning of SNS as a new platform for brand communities, integrating both consumer-brand relationship and brand communities. More specifically, we aim to understand the impact of brand-managed communities embedded in SNS on brand page commitment and brand commitment. Results show that members’ freedom of expression and recognition for contribution on the brand page impact positively brand pages commitment, which in turn impacts brand commitment. Consequently, brand commitment influences the members’ intention to generate positive word-of-mouth about the brand and willingness to engage in co-production. [less ▲]

Massive stars are characterized by a large radiation over gaz pressure ratio and a large temperature over density ratio. With increasing stellar initial mass, they suffer stronger stellar winds which plays an important role in the chemical enrichment of the galaxies. The induced mass loss affects also the evolution and internal structure of massive stars on the main sequence (MS) and on the post-main sequence phase (post-MS). Recent ground-based observations and space missions have shown the presence of pulsations in massive stars, such as accouctic and gravity modes excited by the $\kappa$-mechanism and even solar-like oscillations. Strange modes could also found to be excited in the most massive stars. $\kappa$-mechanism instability domains are presented for the upper HR diagram (up to $70$M$_{odot}$) on the MS and on the post-MS. We compute evolutionary tracks and non-adiabatic frequencies for different input parameters such as the metallicity, the mass loss rate and the overshooting parameter. [less ▲]

This study is an investigation of the impact of brand pages on Social Networking Sites (SNS) in the creation of brand commitment. The main determinants of brand page commitment are evaluated before assessing its impact on brand commitment. Subsequently, some of the potential consequences of brand commitment are assessed. The empirical part of the study was conducted in collaboration with Netlog, the first European SNS. A questionnaire assessing the 9 variables of the model was answered by a sample of 250 Netlogers. The results show that the main determinants of brand page commitment are the freedom to express on the brand page and the recognition for contributing to it. Furthermore, the study revealed a favorable impact of brand page commitment on brand commitment. The two validated consequences of brand commitment in such a context are the intention to generate positive word-of-mouth about the brand and the willingness to co-produce. [less ▲]

The human-macaque interface in Asia is increasingly the focus of numerous studies raising the issue of conflict over space and resources and searching for efficient management strategies. Documenting impacts of interactions with humans and the variations in macaques’ responses to anthropogenic habitats is essential for undertanding adaptation strategies and possibilities of a sustainable coexistence. The long-tailed macaque (Macaca fascicularis) is a very successful commensal species that adapts remarkably well to rural and urban landscapes. In some locations of Bali (Indonesia), this species, which has coexisted with humans for centuries, is used today to promote wildlife-based tourism, often characterized by an intense food provisioning. Here, we present data of a commensal M. fascicularis population in Bali (Uluwatu Temple), particularly well-habituated to human presence and provisioned daily. We analyze the impacts of the daily variations of three anthropogenic factors (microhabitat – human presence degree – food provisioning quantity) on the daily activity, ranging and dietary patterns. We used a focal and scan sampling methodology during a four-month study period between June and October 2010. Four groups constituted this population and their home ranges were particularly small, ranging from 2.4 to 5.6 ha. The eco-behavioural patterns were strongly and consistently influenced by variations in the anthropic factors. Typically, with a high anthropic level (defined as increasing degrees of each anthropogenic factor), macaques spent less time foraging and moving and more time feeding, resting and socializing. Contrary to previous studies on other primate species, we did not find any impact of provisioning on agonistic interactions. 55% of this population’s diet consisted of human foods, while the remainder (45%) of natural foods. Natural food items were preferentially consumed when anthropic level was low, emphasizing the opportunistic style of the diet. In summary, the eco-behavioural modifications induced by variations in anthropic levels did not increase the daily costs of living, confirming the flexibility and the efficiency of the macaques’ responses. However, we also illustrate in another study site (Ubud – Bali) the risk of overpopulation caused by the provisioning, which may potentially increase the human-macaque conflict. [less ▲]

Most of the IPCC-AR4 Atmospheric Global Circulation Models (AGCM) predict an increase of the Antarctic Surface Mass Balance (SMB) during the 21st century that would mitigate global sea level rise. Present accumulation and predicted change are largest at the ice sheet margins because they are driven by snowfall, which mostly comes from warm, moist air arising over the land slopes. The coastal belt is also where complex processes of sublimation, melt and redistribution by the wind occur. Thus, high-resolution modelling (5 to 15 km) is necessary to adequately capture the effects of small-scale variations in topography on the atmospheric variables in this area, but limitations in computing resources prevent such resolution at the scale of Antarctica in full climate models. We present here a downscaling method leading to 15-km SMB resolution for century time-scales over Antarctica. We compute precipitation fields by considering orographic processes induced by the broad-scale and the fine-scale topography, and we estimate sublimation, melting and refreezing with a surface scheme validated for snow and ice-covered land surface. We display the SMB downscaled from LMDZ4 AGCM outputs (~60-km resolution), and compare the agreement of the broad-scale SMB and the downscaled SMB with 20th century observations. Then, we present hi-resolution features of the Antarctic SMB evolution during the 21st century downscaled from LMDZ4 and discuss the effect of the resolution on the Antarctic SMB contribution to sea level change. The downscaling model is a powerful tool that will be applied to others climate models for a better assessment of future sea level rise. [less ▲]
