Questionner le tourisme rural, c’est se poser la question des particularités de celui-ci notamment liées à sa dispersion, à ses difficultés d’organisation en une « destination », à ses représentations idylliques, à ce patrimoine plus ou moins commun, plus ou moins privatisé, que le touriste consomme, aux difficiles questions du partage des revenus du développement touristique, aux problèmes des équipements et surtout de l’accessibilité par transports individuels et collectifs de ces zones excentrées. Autour de quelques collègues soucieux de partager leur enthousiasme pour la recherche, nous avons convié des doctorants à partager dans le cadre d’une journée de l’école doctoral thématique en géographie auprès du Fonds National de la Recherche Scientifique, leurs interrogations et leurs premières investigations. Ce numéro thématique rassemble les principales contributions à cette réflexion commune, en proposant une étude de l'utilisation de l’autoroute pour développer des produits touristiques à proximité d’un flux important de personnes (Malet, 21-35), une analyse de la mise en tourisme d'un produit de terroir et de la manière d'en faire une ressource clé du tourisme régional (De Myttenaere, 37-51), une recherche sur les images et représentations d'une destination rurale et leur utilisation pour développer l’accueil et la promotion (Mazuel et Bonniot, 7-19), une enquête sur le rôle des associations intercommunales et des municipalités dans le développement des entreprises touristiques en milieu rural (Vanneste et Ryckaert 53-71), une réflexion sur la complexité des polémiques autour des loisirs motorisés (Haye et Mounet, 73-84) et enfin une lecture critique de textbooks anglais qui permet de constater le chemin fait et le chemin qui reste à faire pour réellement passer des monographies à des théories du tourisme sensibles aux particularités du milieu rural (Dubois, 85-94).

Cerebral activity associated with recollection and familiarity in 28 patients with Alzheimer’s disease (AD) and 17 healthy controls was directly measured in an event-related fMRI experiment during performance of a recognition memory task with the process dissociation procedure. Brain regions associated to recollection were evidenced by contrasting activations for inclusion and exclusion conditions whereas brain regions related to familiarity were explored with the mean effect of the two conditions (at P < .05 corrected). Twelve patients had null recollection estimates (AD-), whereas 16 patients did experience some recollection although significantly less than controls (AD+). In AD+ and controls, recollection activated the posterior cingulate cortex (PCC). In contrast, familiarity estimates were equivalent in the 3 groups and were associated with brain activations around the intraparietal sulcus (IPS). Thus, in AD, impaired recollection is related to damage of the PCC whereas preserved familiarity is supported by the IPS. [less ▲]

Listeria monocytogenes can proliferate at the beginning of cheesemaking as the conditions favor growth. The objective of this study was to establish the growth limits of L. monocytogenes in a cheese matrix, in case of potential contamination of the milk prior to cheese manufacture. A semisoft laboratory scale model cheese system was made at different initial pH and water activity (a(w)) levels with a mix of two strains of L. monocytogenes. A factorial design of five pH values (5.6 to 6.5), four a(w) values (0.938 to 0.96), and two L. monocytogenes inoculation levels (1 to 20 CFU/ml and 500 to 1,000 CFU/ml) was carried out. Each combination was evaluated in six independent replicates. In order to determine if there was a dominant strain, isolated colonies from the cheeses were analyzed by pulsed-field gel electrophoresis. The data relating to growth initiation were fitted to a logistic regression model. The a(w) of milk influenced the probability of growth initiation of L. monocytogenes at both low and high contamination levels. The pH, at the concentrations tested, had a lower effect on the probability of growth initiation. At pH 6.5 and a(w) of 0.99 for low contamination levels and pH 6.5 and a(w) of 0.97 for high contamination levels, increases in population of up to 4 and 2 log were observed at low and high contamination levels, respectively. This shows that if conditions are favorable for growth initiation at the early stages of the cheesemaking process, contamination of milk, even with low numbers, could lead to L. monocytogenes populations that exceed the European Union's microbiological limit of 100 CFU/g of cheese.

This paper presents a review of studies that were aimed at determining which brain regions are recruited during visual self-recognition, with a particular focus on self-face recognition. A complex bilateral network, involving frontal, parietal and occipital areas, appears to be associated with self-face recognition, with a particularly high implication of the right hemisphere. Results indicate that it remains difficult to determine which specific cognitive operation is reflected by each recruited brain area, in part due to the variability of used control stimuli and experimental tasks. A synthesis of the interpretations provided by previous studies is presented. The relevance of using self-recognition as an indicator of self-awareness is discussed. We argue that a major aim of future research in the field should be to identify more clearly the cognitive operations induced by the perception of the self-face, and search for dissociations between neural correlates and cognitive components.

463 lichen taxa are reported from the island of Reunion (Mascarene archipelago) in the Indian Ocean. This report is based on extensive collections recently made by the authors or hosted in B and LG. A total of c. 600 species is estimated for the number of lichenized fungi present on the island; although this is a low figure for a varied tropi- cal area, this is plausible due to its small size and remoteness. The significance of the lichen diversity of the island lays in its endemics, which need further study for a reliable assessment, and in the occurrence of a poorly known southern hemisphere element (“austral” species). The discovery of the following in Reunion is of special interest as it considerably enlarges their distribution range: Anzia corallophora, Caloplaca caesiosorediata, Coccocarpia delicatula, Fuscopannaria praetermissa, Gomphillus morchelloides, G. pedersenii, Gyalideopsis bispora, Heterodermia koyana, Hypotrachyna evansii, Lithogyalideopsis zeylandica, Lobaria asperula, Megaloblastenia marginiflexa var. dimota, Menegazzia capitata, Myeloconis erumpens and Pannaria squamulosa.

ABSTRACT: Alcelaphine herpesvirus 1 (AlHV-1) is carried by wildebeest asymptomatically. It causes a fatal lymphoproliferative disease named wildebeest-derived malignant catarrhal fever (WD-MCF) when cross-species transmitted to a variety of susceptible species of the Artiodactyla order. WD-MCF can be reproduced experimentally in rabbits. In a previous report, we demonstrated that WD-MCF induced by AlHV-1 is associated with a severe proliferation of CD8+ T cells in the lymphoid tissues. Here, we further studied the mononuclear leukocytic populations in both the lymphoid (throughout the infection and at time of euthanasia) and non-lymphoid (at time of euthanasia) organs during WD-MCF induced experimentally in rabbits. To reach that goal, we performed multi-colour flow cytometry stainings. The results obtained demonstrate that the development of WD-MCF correlates in peripheral blood with a severe increase of CD8+ cell percentages; and that CD3+CD8+CD4- T cells were the predominant cell type in both lymphoid and non-lymphoid organs at time of euthanasia. Further characterization of the mononuclear leukocytes isolated from both lymphoid and non-lymphoid tissues revealed that the CD8+ T cells express high levels of the activation markers CD25 and CD44, produce high amount of gamma-interferon (IFN-gamma) and perforin, and showed a reduction of interleukin-2 (IL-2) gene expression. These data demonstrate that the development of WD-MCF is associated with the expansion and infiltration of activated and cytotoxic CD3+CD8+CD4- T cells secreting high amount of IFN-gamma but low IL-2.

The matching of groups is a traditional way to control for confounding variables in developmental disability research. The equivalency of means across groups is routinely checked for these variables, but not the homogeneity of their variances or the shapes of their distributions. In the present paper, it is argued that group matching can go seriously wrong unless it directly confronts the distributional concerns by the use of well-known statistical indices and very simple graphical displays of the distributions. The question of the equivalency of item response profiles is also addressed since two participants or two groups of participants can obtain the same overall score on the matching variable by passing different items. In this case, the matching cannot be considered satisfactory because of poor concordance between the molar (overall score) and molecular (item scores) levels of matching. Angoff's Delta plot method, a statistical approach for detecting differential item functioning across small groups is described. It is promising as a simple way to prove whole test/individual item correspondence and, in addition, a useful tool for making post-hoc statistical analyses at the item level on the dependant variables.

Efficient design of hydraulic structures such as weirs and bottom outlets requires a detailed description of the complex turbulent flows occurring on these structures. Compared to laboratory experiments, numerical modeling offers more flexibility and cost-effectiveness to test different designs. The non-hydrostatic 2D-vertical model presented here solves the RANS equations for incompressible flows in the vertical plane. It is based on the projection method for pressure-velocity coupling, while free surface tracking is conducted by means of the level set technique and Sussman’s velocity extension algorithm. It enables to predict accurately the flow pattern in the vertical plane and deals with multiple interfaces (jets, drops…). The solver has been validated for both steady and unsteady free surface flows, based on theoretical and experimental data. The paper will detail the application of the model to a pressurized flow and to a sloshing tank. [less ▲]
