La crise généralisée qui, depuis quelques années, a affaibli les économies de nombre d’états, a eu des conséquences sur la typologie des migrations internationales : les trajectoires, les projets, les destinations, les départs se sont modifiés en fonction de nouveaux facteurs auxquels les individus et les groupes étaient confrontés . A côté de ces macro-dynamiques globales, la crise a également engendré des changements dans la vie quotidienne des migrants lorsqu’ils étaient déjà partis et qu’ils s’étaient déjà installés ailleurs. Dans ce cadre, ma contribution vise à analyser les pratiques d’approvisionnement alimentaire d’un groupe de migrantes marocaines en Italie mettant en place des stratégies pour faire face aux conséquences concrètes de la crise économique (notamment la diminution de leur pouvoir d’achat en conséquence de leur précarité professionnelle). Au travers de plusieurs déplacements dans la ville où elles habitaient et de la mobilisation des réseaux familiaux alimentant des circuits informels d’échange de biens, ces femmes satisfaisaient leurs différentes exigences – parmi lesquelles le désir de performer des préparations propres à leur mémoire incorporée – tout en répondant aux contraintes économiques déterminées par la crise. Je vais ainsi démontrer qu’en dépit des difficultés rencontrées, ces femmes arrivaient à exercer une agency dans le nouvel espace vécu et à se positionner de façon active au travers de leurs choix et conduites quotidiennes.

« Savourer la nourriture et respirer la culture marocaine deviennent une expérience et une émotion unique, à découvrir et à vivre grâce à la combinaison d’arômes, goûts, couleurs, formes et musiques ». Au travers de ce slogan, un renommé restaurant d’inspiration marocaine de la ville de Milan en Italie, invitait ses clients à voyager au travers de leur sensorialité dans une culture alimentaire (et par synecdoque, une culture tout court) autre. Le goût les aurait amenés à expérimenter un exotisme, qui était néanmoins contrôlé, car certaines conditions imposées par les normes locales faisaient en sorte que le déplacement vécu ne fût pas excessivement déstabilisant. Le résultat de ces négociations consistait d’un menu qui accostait les gastronomies marocaine et italienne (ou les procédures de l’une et de l’autre) dans certains plats décrits comme « fusion », qui satisfaisaient (ou non) les exigences des clients. Dans cet article, je vise à mettre en évidence les mécanismes de production discursive et matérielle de ces plats, ainsi comme les opinions des consommateurs. Pour ce faire, j’analyserai le matériel ethnographique collecté auprès du local en question en le comparant avec les pratiques observés dans d’autres restaurants milanais. En ce qui concerne les effets obtenus, j’appuierait mon analyse sur une plateforme de médias sociaux consacrée aux recensions d’endroits et locaux touristiques. La culture alimentaire sera étudiée dans ses aspects symboliques mais aussi matériels, en faisant également recours au matériel visuel récolté. [less ▲]

Chlorophyll fluorescence is an information-rich signal which provides an access to the management of light absorbed by PSII. A good example of this is the succession of fast fluorescence fluctuations during light-induced photosynthetic induction after dark-adaptation. During this period, the fluorescence trace exhibits several inflexion points: O-J-I-P-S-M-T. Thereas the OJIP part of this kinetics has been the subject of many studies, the processes that underly the PSMT transient are less understood. Here, we report an analysis of the PSMT phase in the green microalga Haematococcus pluvialis in terms of electron acceptors and light use by photochemistry, fluorescence and non-photochemical quenching (NPQ). We identify additional sub-phases between P and S delimited by an inflexion point, that we name Q, found in the second time-scale. The P-Q phase expresses a transient photochemical quenching specifically due to alternative electron transport to oxygen. During the transition from Q to S, the NPQ increases and then relaxes during the S-M phase in about 1 min. It is suggested that this transient NPQ observed during induction is a high energy state quenching (qE) dependent the alternative electron transport to molecular oxygen. We further show that this NPQ is of the same nature than the NPQ, known as the low-wave phenomenon, which is transiently observed after a saturating light pulse given at steady-state. In both cases, the NPQ is oxygen-dependent. This NPQ is observed at external pH 6.0, but not at pH 7.5, which seems correlated with faster saturation of the PQ pool at pH 6.0. [less ▲]

Since current trends in the transportation, energy or mechanical industries impose increasingly demanding service conditions for metallic parts, metal matrix composites (MMC) are the object of a growing interest. Powder-based laser additive manufacturing, that allows to make parts with complex shapes, appears particularly adapted for the production of MMCs. This paper reviews the current state-of-the-art in the production of MMCs by additive processes, with the aim of assessing the potentials and difficulties offered by these techniques. Two main processing routes are envisaged i.e. (1) the processing of ex-situ composites in which the reinforcing phase as a powder – often of ceramic particles − is directly mixed with the powder of the matrix alloy, and both powders are simultaneously processed by the laser. (2) Alternatively, the reinforcing phase can be produced in-situ by a chemical reaction during the fabrication of the composite. For both processing routes, a careful control is needed to overcome challenges brought e.g. by the behaviour of the reinforcement particles in the laser beam, by changes in laser absorptivity or by the dissolution of the reinforcing particles in the molten metal, in order to produce metal matrix composites with enhanced usage properties.

The study of Antarctic cyanobacterial diversity has been mostly limited to morphological identification and traditional molecular techniques. High-throughput sequencing (HTS) allows a much better understanding of microbial distribution in the environment, but its application is hampered by several methodological and analytical challenges. In this work we explored the use of HTS as a tool for the study of cyanobacterial diversity in Antarctic aquatic mats. Our results highlight the importance of using artificial communities to validate the parameters of the bioinformatics procedure used to analyse natural communities, since pipeline-dependent biases had a strong effect on the observed community structures. Analysis of microbial mats from five Antarctic lakes and an aquatic biofilm from the Sub-Antarctic showed that HTS is a valuable tool for the assessment of cyanobacterial diversity. The majority of the OTUs retrieved were related to filamentous taxa such as Leptolyngbya and Phormidium, which are common genera in Antarctic lacustrine microbial mats. However, other phylotypes related to different taxa such as Geitlerinema, Pseudanabaena, Synechococcus and Chamaesiphon, Calothrix and Coleodesmium were also found. Results revealed a much higher diversity than what had been reported using traditional methods and also highlighted remarkable differences between the cyanobacterial communities of the studied lakes. The aquatic biofilm from the Sub-Antarctic had a distinct cyanobacterial community in comparison to the studied Antarctic lakes, which, in turn, displayed a salinity-dependent community-structure at the phylotype level.

Introduction. Multiple environmental and socio-economic indicators show that our current agriculture and the organization of the food system need to be revised. Agroecology has been proposed as a promising concept for achieving greater sustainability. This paper offers an overview and discussion of the concept based on existing literature and case studies, and explores the way it questions our current research approaches and education paradigms. Literature. In order to improve the sustainability of agriculture, the use of external and chemical inputs needs to be minimized. Agroecological farming practices seek to optimize ecological processes, thus minimizing the need for external inputs by providing an array of ecosystem services. Implementing such practices challenges the current structure of the food system, which has been criticized for its lack of social relevance and economic viability. An agroecological approach includes all stakeholders, from field to fork, in the discussion, design and development of future food systems. This inclusion of various disciplines and stakeholders raises issues about scientists and their research practices, as well as about the education of the next generation of scientists. Conclusions. Agroecology is based on the concept that agricultural practices and food systems cannot be dissociated because they belong to the same natural and socio-economic context. Clearly, agroecology is not a silver-bullet, but its principles can serve as avenues for rethinking the current approaches towards achieving greater sustainability. Adapting research approaches in line with indicators that promote inter- and transdisciplinary research is essential if progress is to be made. [less ▲]

How do contemporary migrant mothers strategize return to their home countries? And how does the social protections available for their bi-national children in sending and destination countries factor in the decision to return? Through this contribution, we aimed to tackle these questions. We draw from the analysis of two longitudinal migratory careers and argue that our participant’s return decisions were influenced both by their children’s effective access to social protection and their subjective perceptions of ‘good-motherhood’. This Trans-Atlantic comparison shows how different situated-institutional-contexts, cultures of care and motherhood resulted into different patterns of mobility for these women and their families.

The procedural deficit hypothesis (Ullman & Pierpont, 2005) has been proposed to account for the combination of linguistic and nonlinguistic deficits observed in specific language impairment (SLI). According to this proposal, SLI results from a deficit in procedural memory that prevents children from developing sensitivity to probabilistic sequences. We tested the ability of children with SLI to rely on a specific type of probabilities characterizing sequences that occur in a given language: phonotactic probabilities. Twenty French-speaking children with SLI (M = 10;1), 20 typically developing children matched for chronological age (M = 10;0) and 20 typically developing children matched for receptive vocabulary (M = 7;4) performed an auditory lexical decision task. Pseudoword stimuli were built with combinations of either frequently associated phonemes (high phonotactic probability) or infrequently associated phonemes (low phonotactic probability). Phonotactic probabilities had a significant impact on the accuracy and speed of pseudoword rejection in children with SLI, but not in the two control groups. SLI children's greater reliance on phonotactic probabilities relative to typically developing children appears to contradict the PD hypothesis. Phonotactic probabilities may help them to partially overcome their difficulties in accessing the phonological lexicon during spoken word recognition. [less ▲]

A systematic study on the presence of bottlenose dolphins (Tursiops truncatus) in the Río Negro Estuary (RNE), Patagonia Argentina, was carried out between the months March – July from 2008 to 2011. Data on the dolphin’s activity patterns were gathered via an Ad Libitum focal group sampling mode accompanying dorsal fin images taken for identification and re-identification of individuals. A total effort of 188 h resulted in 58 h of positive observation of 124 dolphin groups (sightings per unit effort (SPUE) = 0.66 groups/h). Data analysis showed two main activity states for the observed groups, travelling (65%) and foraging (26%). The remaining 9% of the groups were involved in other activity states. The photo-identification effort, which started opportunistically in 2006, resulted in a catalogue of 21 individual dolphins, with a total mean re-identification rate of 9 days (max = 24 days). When comparing these pictures to the existing catalogue of Bahía San Antonio (approximately 200 km west from the study area) dorsal fins of 20 individuals could be positively matched and most (n = 17) could be subsequently re-identified in both areas, indicating their long distance movements along the North Patagonian coast during the austral autumn months. This season coincides with the lowest amount of feeding activity observed in Bahía San Antonio. This study suggests that bottlenose dolphins enter RNE, mainly during autumn, to forage. It appears that the search for food resources may be the trigger for their movement patterns along the North Patagonian coast during this season, at least for certain individuals. More research is needed to accurately confirm this hypothesis. [less ▲]

We examine different aspects of energy conservation in the case of the analytical solution of Ritter for idealized dam break flow in a horizontal frictionless and dry channel. We detail the application of the unsteady Bernoulli equation in this case and highlight that the inertial effects cancel out when averaged over the whole flow region. We also show that the potential and kinetic contributions to the total mechanical energy in the flow region have a distinct and constant relative importance: potential energy accounts for 60 %, and kinetic energy for 40 % of the total mechanical energy. These properties of Ritter solution are rarely emphasized while they may be of practical relevance, particularly for the verification of numerical schemes with respect to their ability to ensure energy conservation.
