Carapidae (or pearlfish) are eel-like fishes living inside different invertebrates, such as holothurians, sea stars or bivalves. In some Polynesian areas where they live in sympatry, <br />several species (Carapus homei, Carapus mourlani, Carapus boraborensis and Encheliophis <br />gracilis) are able to inhabit the same host species. The heterospecific infestation rate is very rare, suggesting that the four species can compete for their hosts. Some differences in <br />settlement period, breeding period and in pelagic larval duration (PLD) could allow better characterisation of the life history of each species. More than 700 larvae were collected during an entire year on the Rangiroa atoll (French Polynesia). Each species was identified; their settlement pattern was examined and their PLD was deduced from otolith (sagittae) increments. In the four collected species, the settlement pattern differed: C. homei and C. mourlani settle on the reef during the entire year, and show an asynchronous and diffuse breeding cycle. C. boraborensis and E. gracilis have a shorter settlement period which could be compatible with breeding synchronisation. As most reef fishes, Carapidae larvae mainly settle during moonless nights. Moreover, each species presents some plasticity, allowing it to settle on the reef under suitable conditions. [less ▲]

We define the pion-photon transition distribution amplitudes (TDA) in a field theoretic formalism from a covariant Bethe-Salpeter approach for the determination of the bound state. We apply our formalism to the Nambu-Jona-Lasinio model, as a realistic theory of the pion. The obtained vector and axial TDAs satisfy all features required by general considerations. In particular, sum rules and the polynomiality condition are explicitly verified. We have numerically proved that the odd coefficients in the polynomiality expansion of the vector TDA vanish in the chiral limit. The role of PCAC and the presence of a pion pole are explicitly shown. © 2007 The American Physical Society. [less ▲]

Le rôle joué par les médias de masse dans un certain nombre de phénomènes politiques et sociaux contemporains est régulièrement dénoncé et critiqué, la plupart du temps sans être appréhendé de manière précise mais en se fondant sur leurs effets supposés. Par une analyse des discours de presse qui ont entouré le « Dimanche noir » du 21 avril 2002, cet ouvrage propose de revenir sur le paradoxe apparent qui vit, lors de cette campagne présidentielle, un candidat déclaré illégitime par la presse remporter un succès électoral inattendu. L’analyse montre comment des discours massivement dénonciateurs ont eu des effets de légitimation contraires aux intentions des auteurs et au contenu même de leurs propos. Son originalité est de s’intéresser, au-delà de la machine médiatique et des composantes langagières des discours, à la relation que les journalistes proposent à leurs lecteurs. Elle se réfère également à un certain nombre de mythes qui orientent l’écriture journalistique pour mettre en lumière la contradiction entre l’engagement des journalistes dans des valeurs de « défense de la démocratie » et la caution qu’ils se donnent d’un discours objectif. Elle démonte ainsi l’ensemble d’un dispositif d’écriture contre-productif qui, s’il n’est pas seul en cause, éclaire néanmoins d’un jour nouveau le rôle des médias dans le succès électoral de Jean-Marie Le Pen, et en appelle à la responsabilité de la presse.

For obligate plant-parasitic nematodes, cryopreservation has advantages over the usual preservation methods on whole plants or axenic culture systems, because the latter two are labourious and time and space consuming. In addition, cross contamination among different isolates can occur easily. Moreover, specific genetic studies require maintenance of the original population. The nematode under investigation, Radopholus similis, is a plant-parasitic nematode from the humid tropics. Therefore, any treatment at low temperatures is likely to add extra stress to the nematode, making the development of a cryopreservation protocol extremely difficult. In this paper, we describe experiments to achieve a successful cryopreservation protocol for the tropical nematode R. similis using vitrification solution-based methods based on a well defined mixture of cryoprotectants in combination with ultra-rapid cooling and thawing rates. A two-step treatment was used consisting of an incubation in glycerol followed by the application of a vitrifying mixture of methanol, glycerol and glucose. After cryopreservation, the athogenicity of the nematodes was not altered, since they could infect and reproduce on carrot discs after recovery in the Ringer solution. The cryopreservation method described can be used for routine cryopreservation of R. similis lines from different origins. [less ▲]

Suppose that the random vector (X, Y) satisfies the regression model Y = m(X) + sigma(X)epsilon, where m(.) = E(Y vertical bar.) belongs to some parametric class (m(theta)(.):theta is an element of Theta) of regression functions, sigma(2)(.) = var(Y vertical bar.) is unknown, and e is independent of X. The response Y is subject to random right censoring, and the covariate X is completely observed. A new estimation procedure for the true, unknown parameter vector theta(0) is proposed that extends the classical least squares procedure for nonlinear regression to the case where the response is subject to censoring. The consistency and asymptotic normality of the proposed estimator are established. The estimator is compared through simulations with an estimator proposed by Stute in 1999, and both methods are also applied to a fatigue life dataset of strain-controlled materials. [less ▲]

Many authors have pointed to a lack of clarity in the existing case law of EC courts in the field of competition law regarding the allocation of the burden of proof, as well as the determination of the standard of proof. This article attempts to clarify the concepts underlying these questions, bearing in mind that the Court reasons in more than one language. It consists in three sections. The first section is of a theoretical nature. It shows how questions regarding the allocation of the burden of proof and judicial control are conceptualised differently in different legal traditions. It also attempts to clarify the notions of burden of proof, standard of proof and standard of control. With regard to these notions, as is often the case, EC case law appears to be a melting pot of different legal traditions. It is thus shown that notions originating both in the common law and in the civil law tradition are useful to understand EC case law in relation to the issues of proof and control. The second section is more descriptive. It states the current law and illustrates with examples from court cases the usefulness of the various notions defined in the first section. It leads to the conclusion that the common law notions of standard of proof and standard of control are not sufficient to understand the intensity of control applied by Community courts over Commission’s decisions. The third section proposes another description of judicial control, based on the notions of “scenario” (depicting the economic story line adduced by the Commission to account for anticompetitive effect) and “economic normality”, as perceived by judges.

This article revisits the definition of predation in light of recent economic analysis, which emphasises the importance of strategic consideration. It goes on to analyse recent French and EU case law on predatory pricing. It is argued that recent French decisional practice could be viewed as a model for incorporating insights from economics in a methodolically sound manner. [less ▲]
