Les multiples systèmes, formes, catégories et pratiques de la parenté ont retenu l’attention des anthropologues comme une dimension centrale des façons dont les individus et les groupes humains conçoivent et vivent leurs rapports à eux-mêmes, aux autres, aux sociétés et au monde qui les entoure. Dans différents contextes et périodes historiques, des évolutions – tant démographiques, politiques, socio-culturelles, économiques, juridiques, scientifiques, médicales, ou encore relatives aux âges ou aux genres – ont contribué à sa (re)définition constante. Force est de constater que les innovations récentes concernant, entre autres, les technologies de procréation médicalement assistée et de gestation pour autrui, ou les débats autour du « mariage pour tous » et de l’adoption par des couples du même sexe, ont parfois été interprétés en termes de profondes ruptures par rapport à des conceptions plus « traditionnelles » de la parenté, ce qui leur confère un certain caractère inédit et polémique. D’un point de vue anthropologique, ces reconfigurations de la parenté témoignent de différentes modalités d’articulation entre le social, le culturel et le biologique, faits de société et faits de nature, construit et inné, dans la définition de la parenté. Cela amène à repenser la parenté dans toutes ses dimensions, du public à l’intime. Partant de l’anthropologie, et afin d’élargir le champ des réflexions empiriques, théoriques et épistémologiques, ce colloque invite à croiser les perspectives sur les (re)configurations contemporaines de la parenté dans les sciences humaines et sociales en privilégiant les approches ethnographiques. Il comprend deux axes principaux mais non exclusifs. Le premier axe entend appréhender les manières dont la question des (re)configurations contemporaines de la parenté est posée dans différents espaces publics et intimes. Le second axe ouvre quant à lui un débat épistémologique sur les regards croisés et comparatifs entre divers contextes, thématiques ou disciplines en invitant à analyser les enjeux, apports et limites issus de tels travaux de recherche.

Equol is a microbial metabolite of isoflavones that could be used as therapeutic agent against several diseases and cancers. Cow's milk could be a potential source of equol in the human diet, but more studies are needed on the changes in equol concentration during the technological processing of milk and dairy products. This first exploratory study sought to assess the impact of industrial skimming and microfiltration processes on equol concentration in conventional cow's milk. The milk samples used in this study came from bulk cow’s milk collected in Wallonia (Belgium), by a local dairy and processed in a local cheese factory. Six random sampling were conducted during spring and, for each of them, samples from raw, skimmed and microfiltered milk were analyzed. Equol was present in all samples at a concentration of between 3.2 and 10.3 µg.L-1. A Wilcoxon's signed rank test was then performed on the difference of data, having raw milk as reference, irrespective of the collection date. The results showed that the skimming process slightly increased the equol concentration in milk and therefore that equol had no or little affinity with the lipid milk fraction. The results also showed that, with the microfiltration process, a small proportion of equol was retained. Equol concentration has returned to the same level as that found in raw milk. This might be because of a chemical affinity either with bigger molecules that are physically retained or through direct interaction with the membrane. This scoping study paves the way for more extensive studies on the interaction between equol and other components of the milk. [less ▲]

Dans le champ intellectuel contemporain, la pensée de Paul Ricœur semble avoir pleinement intégré l’outillage conceptuel requis pour penser les identités et modes de subjectivation. Contre les conceptions du texte comme espace formel autorégulé, Ricœur a décrit le récit comme un dispositif cognitif fondamental, offrant aux individus et aux collectivités des modes de subjectivation et des prises sur le monde. Cette approche constitue un bénéfice disciplinaire non- négligeable pour les sciences humaines. Cette actualité de Ricœur peut sembler paradoxale. Certes, le concept de refiguration permet de penser les effets du récit dans le monde, à une époque où la diffusion massive d’information nécessite de capter l’attention par des récits efficaces (storytelling en politique, publicité, management, infotainment). Par contre, le concept d’identité narrative ne semble pas pouvoir se justifier de la même actualité. En effet, quoi de plus opposé à nos expériences démultipliées que cette forme narrative qui devrait les ordonner dans un récit unique ? Quoi de plus hétérogène que le vécu de l’individu contemporain, sans cesse sommé de s’adapter à de nouveaux rôles et de nouveaux projets ? Dans le cadre de cette communication, notre objectif sera d’évaluer la pertinence du concept d’identité narrative pour penser les modes de subjectivation individuelle, par le prisme de plusieurs romans contemporains (Farah, Delaume, Mérot, Minard, de Toledo, Vasset). Comment le récit de vie littéraire développe-t-il des formes qui puissent répondre aux expériences fragmentaires des sujets ? Ces formes renouvellent-elles l’usage de la narration et/ou de la fiction ? [less ▲]

The workshop represents a joint effort between the World Association for Waterborne Transport Infrastructure (PIANC), the National Waterway Transportation Agency (ANTAQ) and the Economic Commission for Latin America and the Caribbean (ECLAC) to promote a regional dialogue on South American inland waterways of international and local importance. Organized within the framework of the COPEDEC 2016 Conference, the workshop targets regional and international experts and decision makers from Latin American countries which share significant inland waterway networks. The workshop builds upon a series of previous events organized by PIANC, such as the Smart Rivers Conference (Buenos Aires, 2015), as well as ECLAC’s work on inland shipping in South America and the results of the ECLAC international seminar on River Mobility in Amazonia held in Quito in May 2016. The main objective of the workshop is to offer decision makers, national experts and technical advisers an opportunity to share their experiences and exchange views on the challenges and potential for inland waterways development in South America. Particular attention will be paid to the role that inland waterways can play on a more sustainable use of the region’s natural resources. The workshop will be structured around three main topics: Inland waterways infrastructure, i.e. identification of the economic potential of national and regional inland waterways classification, Funding Schemes for Inland Waterway Development, i.e. trends and challenges in public and private investment in inland waterways, Policies and governance for inland waterways, i.e. the building blocks of a national and regional policy on inland waterways development and institutional framework.

Une perspicacité rare, mêlant sens du sacré et sens du réel, ainsi qu’un fonctionnement démocratique radical : chacun-e participe librement aux délibérations et à la lutte, qui est permanente… <br />Pour Sarayaku, cette lutte s’inscrit dans la durée, avec panache: création d’une ceinture d’arbres à fleurs, visible du ciel sur des dizaines de kilomètres (« Frontière de Vie »); proposition à l’ONU d’un statut innovant pour les aires protégées (« Forêt Vivante »). <br />Depuis le cœur de l’Amazonie, Sarayaku se tient prêt pour les moments de vérités présents et à venir. Rencontrer ce peuple, c’est rencontrer un allié, indomptable et éclairant. <br />José Gualinga est ex-président de Sarayaku et président de l'association Atayak en charge de la Frontière de vie, d'un centre de santé traditionnel, d'une école biculturelle, d'un jardin botanique et de plantes médicinales.

Ion mobility spectrometry (IMS) is a gas phase separation technique which relies on differences in the collisional cross section (CCS) of ions. Ionic clouds of unresolved conformers overlapped if the CCS difference is below the instrumental resolution expressed as Ω/ΔΩ. The experimental arrival time distribution (ATD) peak is then a superimposition of the various contributions weighted by their relative intensities. We have developed a strategy for accurate drift time determination using traveling wave ion mobility spectrometry (TWIMS) of poorly and unresolved conformers. This method implements through a calibration procedure the link between the peak full width at half maximum (FWHM) and the drift time of model compounds for wide range of settings for wave heights and velocities. We modified a Gaussian equation which achieves the deconvolution of ATD peaks where the FWHM is fixed according to our calibration procedure. The new fitting Gaussian equation only depends on two parameters: The apex of the peak (A) and the mean drift time value (µ). The standard deviation parameter (correlated to FWHM) becomes a function of the drift time. This correlation function between µ and FWHM is obtained using the TWIMS calibration procedure which determines the maximum instrumental ion beam diffusion using ionic compounds which are detected as single conformers in the gas phase. This deconvolution process has been used to highlight the presence of poorly resolved conformers for couples of crown ethers and peptides leading to CCS determination in better agreement with quantum chemistry predictions.

Vertical matter transfer processes (bioturbation and <2μm translocation) in soils and their dynamics are up to now poorly constrained although they are responsible for the temporal evolution of the ecosystem services. In order to better constrain and quantify these processes, a kinetic quantification of the involved transfers based on vertical profiles of 210Pb (xs), 10Be and 137Cs has been developed for Luvisols in which soluble transfers could be neglected. The range of applicability of this type of approach was nevertheless not tested. In this work, we analyzed 210Pb (xs), 10Be and 137Cs in soils exhibiting gradients of organic matter, pH and < 2 μm fraction (Podzol, Andosol Ferralsol, Leptosol). Acidic soils and large organic matter contents were considered. The depth distribution of the studied isotopes was then interpreted as a function of the organic matter content, the soil pH and its < 2 μm fraction. This demonstrates that 10Be and 137Cs losses occur under soluble form in the Podzol, especially under forest, more acid, for the latter. Soluble 10Be transfers were also identified in the Andosol when they were considered as negligible in the Leptosol. For 210Pb (xs), soluble transfers are also probable for soils with pH less than 5.5 (Andosol and Ferralsol) and strong affinity for organic matter has been demonstrated. Thus, under acidic conditions and low < 2 μm fraction, soluble transfer cannot neglected anymore. [less ▲]

Laser cooling and trapping techniques enjoy a solid reputation as powerful and elegant providers of well-localized, backing-free sources. Not only does this hold true within the atomic physics and quantum optics communities, but also beyond. Most notably, these techniques have recently joined the toolbox of low-energy, high-precision tests of the Standard Model. Our work with argon falls within the subset of nuclear beta decay studies, which have historically played a key role in establishing and testing our understanding of weak-interaction physics. In this framework, precision measurements of the beta asymmetry correlation parameter in the beta decay of Ar-35 have been identified as one promising probe for physics beyond the Standard Model. Our current work focuses on the development of a test magneto-optical trap (MOT) setup for Ar-40 as a preliminary step towards cooling and trapping Ar-35 atoms. In particular, much effort is being put into optimizing the efficiency of our source apparatus, which is crucial to achieving high enough statistics in the final trap. We present the current status of the experimental realization of our setup. Measuring the beta asymmetry correlation parameter requires highly spin-polarized samples. Therefore, in parallel to our experimental work, we are numerically investigating methods for generating, controlling and precisely measuring the degree of spin polarization of a sample of Ar-35 atoms. We also aim at being able to quickly switch between a polarized and a non-polarized sample so as to better understand systematic effects. We report on the progress of our theoretical modeling.

Marine magnoliophytes are major primary producers in coastal benthic habitats worldwide. They play a crucial role in the global carbon cycle (one of the more efficient blue carbon wells). Hence, it is necessary to characterise the eco-systemic services seagrass meadows provide. Posidonia oceanica (L.) Delile, the main Mediterranean seagrass species, has high foliar and belowground biomass production. Several methods have been used so far to measure its primary production (e.g., using incubation bells, optodes, biomass and elementary content measurements). A less used method relies on chlorophyll fluorescence measurements through the Pulse Amplitude Modulated (PAM) fluorometry method (Diving - PAM). In the framework of the STARECAPMED project, this study aimed to determine weekly to bimonthly over a one-year period the photosynthetic responses (Yield, relative Electron Transfer Rate, Rapid Light Curve) of P. oceanica. The survey was performed at 10m depth in a pristine meadow (Calvi, Corsica, France). To obtain reliable and comparable data, the protocol was standardized: measurements were performed on the convex middle part of the third leaf, at zenith, during shiny and calm weather days. Results showed that the plant displayed a well-marked seasonality. The mean ETR (μmol e- m-2 s-1 ) of the plant ranged from 2.17 in winter to 21.9 in summer and was linearly correlated throughout the year with the in situ irradiance (PAR irradiance taken perpendicularly to the surface, in the average leaf orientation). The ETR plateaus of the RLCs, ranging from 10.9 to 35.0, and their corresponding maximum PAR intensities evolved similarly. These results demonstrated both the adaptation and the seasonal plasticity of the meadow’s photosynthetic system. Overall the non-destructive PAM technique is a powerful and cost-effective tool to assess the primary productivity of seagrass meadows where other techniques (e.g. optodes) cannot be used and when direct sampling (e.g. biomass measurements) is not allowed.
