Introduction Different methods for in-vivo characterization have resulted in different maps of the human dorsal premotor cortex (PMd): Task-based functional studies suggested a rostro-caudal gradient corresponding to a cognitive-motor gradient1,2 and mapping based on resting-state functional connectivity (RSFC) likewise suggested a subdivision along the rostro-caudal axis3. In contrast, mapping based on structural connectivity as assessed by probabilistic diffusion tractography (PDT) provided evidence that the dorsal part of the precentral gyrus (PG) is organized along a ventro-dorsal axis4. However, there is currently no multimodal mapping of a broadly defined PMd. The present study used a multimodal approach to (1) identify a robust topographical organization of the right PMd by using connectivity-based parcellation (CBP) applied to a meta-analytic approach of task-related coactivation data (i.e. meta-analytic connectivity modeling, MACM5,6), and (2) examine whether the thus obtained parcellation pattern would be reproduced by CBP based on two other connectivity modalities: unconstrained functional (as reflected by RSFC) and structural as measured by PDT based on diffusion-weighted imaging (DWI). Methods A volume of interest (VOI) was defined by merging PMd activation sites from several meta-analyses serving as robust functional localizers of the PMd while excluding primary sensorimotor areas. MACM-CBP6 was performed using Brainmap database. RSFC-CBP and PDT-CBP were performed on distinct datasets to ensure independent parcellation7. RSFC-CBP was computed on RS data of 124 healthy subjects (age: 39.5 ± 11.5 yrs., 66 males) from the 1000BRAINS project8. The voxels’ time series (TS) were first cleaned from confounding effects using PCA denoising and global signal regression. RSFC was then computed by Pearson correlations between the TS of the VOI voxels and those of the rest of the brain. PDT-CBP9 was performed on DWI data of 20 healthy subjects (age: 18.5 ± .76, 10 males) using FSL. Several cluster solutions (k solution) were examined with k-means for MACM- and RSFC-CBP and spectral clustering for PDT-CBP. The choice of the k solution was driven by task-based functional data (MACM) based on three criteria: variation of information, percentage of deviants, and silhouette value6. Results The selected criteria jointly identified the 5-cluster (5k) solution as optimal across the range of functional studies from Brainmap database (Figure 1). Examination of stability across subjects following PDT-CBP further suggested that k=5 may be considered a local optimum within 2 ≤ k ≤ 6. This solution revealed a similar pattern of topographical organization across modalities (Figure 2) with a subdivision along both rostro-caudal and ventro-dorsal axes, including a rostral cluster lying mainly anteriorly to the PG, a central one at the intersection of the precentral sulcus and the superior frontal gyrus, a caudal one in the posterior part of the PG, a ventral one adjacent to ventral PM, and a dorsal one adjacent to the inter-hemispheric premotor areas. Discussion For the first time our study revealed that the PMd could be divided along two axes: rostro-caudal and ventro-dorsal. This is consistent with previous functional2 and microstructure studies10 in humans and non-human primates suggesting a rostro-caudal distinction and with a previous PDT-CBP of the (dorsal) precentral gyrus4 showing that it could be subdivided in the ventro-dorsal direction. Importantly, this topographical organization was found in the independent analysis of three different connectivity aspects: task functional, unconstrained functional and structural, each based on different datasets. In sum, different modalities consistently show that the PMd can be subdivided into 5 subregions organized along both rostro-caudal and ventro-dorsal axes, comprehensively integrating patterns previously revealed by different methods.

This work studies the scaling properties of Mars topography based on Mars Orbiter Laser Altimeter (MOLA) data through the wavelet leaders method (WLM). This approach shows a scale break at 15 km. At small scales, these topographic profiles display a monofractal behavior while a multifractal nature is observed at large scales. The scaling exponents are greater at small scales. They also seem to be influenced by latitude and may indicate a slight anisotropy in topography. [less ▲]

Introduction: Resting-state (RS) functional connectivity (FC) analysis has become a widely used method for the investigation of human brain connectivity and pathology. While most of the current applications are based on data-driven analyses, the use of functionally specific, a priori defined networks provided by neuroimaging meta-analyses represent an important alternative to these, as they allow the standardized assessment of connectivity patterns. Neuronal activity as measured by functional MRI is influenced by various nuisance signals including system noise, thermal noise, and noise induced by physiological processes of the participant. The presence of these confounds in turn have an impact on the estimation of functional connectivity. Several methods exist to deal with this predicament, but little consensus has yet been reached on the most appropriate approach. Given the crucial importance of reliability for the development of clinical applications, we investigated the test-retest reliability of FC analyses in meta-analytically defined networks after removing confounding noise regressors. Methods: RS-fMRI data of 42 healthy subjects with an average age of 42 ± 20 years were obtained in two sessions with an average time interval of 175 ± 75 days. A seed-based FC analysis was conducted after spatial preprocessing, approach specific confound-regression, and band-pass filtering [0.01-0.08 Hz]. We focused on the effects of various commonly used confound removals in the resting state studies such as PCA de-noising, global mean signal regression, and removal of tissue-class specific mean signals (in particular, white matter (WM) + cerebrospinal fluid (CSF) and WM + CSF + grey matter (GM)) [2,3,4,5,7]. Additionally, we examined GM specific time-series extraction from seed regions. In order to compute the seed based FC, a priori defined networks were analyzed (extended socio-affective default mode [1] and working-memory [6]). Both networks show robust within network resting state connectivity as well as anti-correlation between each other. The reliability of FC was measured using two different measures Spearman correlations and the absolute differences of functional connectivity scores. The different approaches defined by the combination of different masking / confound removal approaches were compared using a non-parametric Friedman ANOVA. Results: The summary ranking across both indices of reliability (Spearman correlations and absolute differences) reflects the major patterns noted in the individual analyses (Fig.1). GM masking, in particular using the group-mean segmentation, improves reliability. PCA denoising in turn reduces it. Within-network connections are most reliably estimated when not using any global or tissue-class specific signal regression, with removing the global WM and CSF signals representing the next-best approach. In contrast, between-network connections are most reliably measured by linear and second order removal of global signals of all three-tissue classes. Conclusion: Our results show that GM masking of the seed regions based on the group-average GM probabilities is advisable when investigating meta-analytically defined networks. In turn, PCA de-noising reduces the reliability of connectivity estimates. Finally, with respect to global signal regression, we observe that refraining from this approach enhances reliability, but comes at the expense of potentially poorer biological validity, indicated by missing anti-correlations between what has been previously described as antagonistic networks. Here, removal of global WM and CSF signals seems to provide a good compromise, as this approach yielded reliable and meaningful estimates of within and between-network connections (Fig.2). We noted that reliability is proportional to the retained variance, presumably including structured noise. Consequently, we would argue that compromises are needed between maximizing reliability and removing variance that may be attributable to non-neuronal sources. [less ▲]

The mere exposure effect is usually considered a robust phenomenon whereby people’s attitudes can easily be influenced. However, recent studies suggest that some conditions must be met for this effect to emerge. In this experiment, the influence of the features of a specific material on the mere exposure effect was examined in an ecological context. Children were told that they would play a game during which they would have to buy several items in different shops. In these shops, half of the participants were incidentally exposed to two target stimuli. During a subsequent judgment phase, the target stimuli were presented to each child, either with perceptually similar items or with perceptually dissimilar items. Prior encounter with an item only influenced children’s preference choices when the test items were dissimilar. These findings are discussed in terms of the processing styles that are necessary for the mere exposure effect to appear. [less ▲]

Grasslands are an important component of the global carbon balance but their carbon storage potential is still highly uncertain. Especially, the impact of weather variability and management practices on grassland carbon budgets need to be assessed. This study investigates the carbon balance of an intensively managed permanent grassland in southern Belgium and its uncertainties by combining 5-years of eddy covariance measurements and other organic carbon exchanges estimates. The specificities of this study lie in: (i) the age of the pasture, which has probably been established since more than one century; (ii) the intensive character of the management with a mean grazing pressure larger than 2 livestock unit ha-1 and stocking cycle including stocking and rest periods, (iii) the livestock production system, typical of Wallonia, farming intensively Belgian Blue breed of cattle in order to produce meat. The results showed that, despite the high stocking rate and the old age of the pasture and the high stocking rate, the site acted as a relatively stable carbon sink from year to year with a 5-year average Net Biome Productivity of ‒173 [‒128 ‒203] g C m-2 yr-1. The carbon sink behavior of the pasture was directly increased by management practices through food complementation and organic fertilization and indirectly by mineral fertilization. The relatively low carbon budget inter-annual variability could be explained both by: (i) grazing management of the farmer that regulated Growth Primary Productivity by adapting the stocking rate to the Leaf Area Index which itself depends on weather conditions, (ii) carbon imports through food complements only when grass regrowth was not sufficient to feed the cattle. An exception occurred when low temperatures at the beginning of the year and a prolonged snow period provoked a delay in grass growth and therefore Growth Primary Productivity that could not be completely offset during the rest of the year. The results suggest that management practices that tend to optimize forage availability for meat production could contribute to maintaining a carbon sink. [less ▲]

Despite his long expositions and treatises dealing with martyrial heroism, Tertullian does not seem to have influenced the North African hagiographical production (iind-vith centuries), while Cyprian did it deeply. This article aims to show that the influence of the african rhetor was yet genuine. If it is difficult to detect in the Passio sanctarum Perpetuae et Felicitatis, we can find it in donatist hagiography and above all in hagiographic texts from Mauretania Caesariensis. By studying themes and literary echoes coming from Tertullian’s work, this contribution wants to help with a better comprehension of the legacy left by the rhetor in a literary genre which is not much examine from this point of view. It also wants to highlight the cultural vitality of Mauretania Caesariensis during late Antiquity. [less ▲]

The present paper summarizes the key points of the European NoWaste Project, which aims at developing Rankine cycle systems for integration into long-haul trucks with the aim to convert the waste heat of the exhaust gases into useful energy usable in mechanical or electrical form. The first part of the paper describes the ORC system architectures defined for two different truck engines: one with EGR and the other one without EGR. For both engines, different cycle configurations and working fluids are compared in terms of energy performance and technical constraints. For both ORC systems, the paper shows the final technical choices made in terms of main components: boiler, condenser, expander and pump. The second part of the paper presents preliminary experimental results carried out on demonstrators of the two ORC systems. The objectives of these tests were to check the performance announced by the components’ manufacturers. Finally, the last part of the paper compares the cost of both systems. [less ▲]

demander dans quelle mesure l’injonction du brigand qui exige « la bourse ou la vie ! » peut être comparée à la norme de comportement édictée par un Etat sous la forme d’une loi, c’est poser la sempiternelle question de la frontière qui sépare le droit du non-droit, tout au moins dans une perspective juspositiviste, en tant que cette école de théorie du droit refuse de définir le phénomène juridique en se référant à une valeur ou un ensemble de valeurs. La frontière du droit et du non-droit est en effet particulièrement difficile à tracer, nonobstant plusieurs siècles de discussions philosophiques à ce sujet. Lorsque, fatigué de parcourir les chemins, le brigand décide de s’installer en ville pour s’y adonner au racket des commerçants du quartier et qu’il s’adjoint ensuite le concours d’autres bandits, c’est un gang de malfaiteurs qui voit le jour. Si, ultérieurement, ce gang se concerte avec d’autres bandes de truands pour s’épauler mutuellement dans les exactions auxquelles ils se livrent sur leurs territoires respectifs, il prend alors la forme d’une organisation criminelle ou, au sens large du terme, d’une « mafia ». Le cinéma de Francis Ford Coppola, Martin Scorsese, Brian De Palma, Sergio Leone ou bien encore Matteo Garrone, entre autres, dépeint, souvent avec réalisme, la genèse et le fonctionnement de telles organisations criminelles. La communication a proposé, au moyen d’illustrations tirées des films de ces grands cinéastes, une analyse de microscopie juridique du crime organisé. Une description serrée de la particule élémentaire du phénomène juridique, identifiée par Lucien François dans son ouvrage de théorie du droit Le cap des Tempêtes sous l’appellation de « jurème », met en lumière une indéniable proximité entre les techniques de pouvoir utilisées respectivement par le brigand isolé, la bande organisée et l’Etat souverain. En remontant ensuite vers la structure plus complexe d’un système étatique, on se demandera si, en fin de compte, dans la vision juspositiviste poussée au bout de sa logique par Lucien François, l’Etat ne pourrait être réduit, d’un point de vue ontologique, à un pouvoir de fait comparable, par les techniques de contrainte qu’il exerce sur ses sujets, à une organisation criminelle – abstraction faite des valeurs promues ou poursuivies par tel ou tel appareil étatique.

One of the questions raised by the meeting of these two practices is about the nature of this interaction soccer-advertising. When scrutinizes closely, one realizes that advertising discourse that unfolds on the football field seems to strive to incorporate into its narrative codes of this discipline, it tries to reshape at will to fulfill its own pragmatic goals, which are registered in an argumentative persuasive Contract type opposite to those of football, which basically works based on a dichotomous rhetoric and diagram of the test. This can be seen especially through the exploitation by advertisers of functional units of the footballing universe, such players, the ball, the view of the stadium, etc., which they associate with their products. Our work intend to identify and describe the semiotic structures through which football-advertising encounter takes place, so to realize this duplication. We focus on football stadiums. [less ▲]

The eddy covariance technique is widely used to measure CO2 and other gas fluxes. However, eddy covariance fluxes are affected by systematic errors that must be corrected. Among them, high frequency loss corrections are particularly important in this regard, especially when using a closed-path infrared gas analyzer. In this study, we compared three approaches to do these corrections for CO2 fluxes and evaluated their impact on the carbon balance an intensively grazed grassland site in Belgium . In the first approach, the computation of correction factors was based on the measured sensible heat cospectra (‘local’ cospectra), whereas the other two were based on theoretical models (Kaimal et al., 1972). The correction approaches were validated by comparing the nighttime eddy covariance CO2 fluxes corrected with each approach and in situ soil respiration measurements. We found that the local cospectra differed from the Kaimal theoretical shape, although the site could not be considered ‘difficult’ (i.e., fairly flat, homogeneous, low vegetation, sufficient measurement height), appearing less peaked in the inertial subrange. This difference greatly affected the correction factor, especially for night fluxes. Night fluxes measured by eddy covariance were found to be in good accord with in situ soil respiration measurements when corrected with local cospectra and to be overestimated when corrected with Kaimal cospectra. As the difference between correction factors was larger in stable than unstable conditions, this acts as a selective systematic error and has an important impact on annual fluxes. On the basis of a 4-year average, at DTO the errors reach 71-150 g C m-2 y-1 for net ecosystem exchange (NEE), 280-562 g C m-2 y-1 for total ecosystem respiration (TER) and 209-412 g C m-2 y-1 for gross primary productivity (GPP), depending on the approach used. We finally encourage site PIs to check the cospectrum shape at their sites and, if necessary, compute frequency correction factors on the basis of local cospectra rather than on Kaimal cospectra.

Le présent projet de communication propose une étude sur la manière de représenter la violence ainsi que son instrumentalisation à des fins personnelles dans des actes relevant de la pratique notariale aux XVIIe et XVIIIe siècles à Liège. L’analyse de ces sources est novatrice pour une histoire de la criminalité. En effet, les historiens se sont avant tout centrés sur les archives des cours judiciaires. Il semble cependant que les populations d’Ancien Régime n’allaient pas systématiquement devant le juge pour régler leurs conflits. Ainsi des accords, qui ne seraient sans doute jamais parvenus à la connaissance de l’historien par la seule étude des archives criminelles, émergent dans les actes relevant de la pratique notariale. Outre ces accommodements clairement identifiés dans les minutes, les populations d’Ancien Régime se déplacent également devant notaires pour que ceux-ci retranscrivent, plus ou moins fidèlement, le récit subjectif d’un évènement vécu. Ces déclarations criminelles seront ensuite, selon le choix du comparant, enregistrées ou non au greffe. En effet, cette trace d’accusation ou de témoignage ne parvient pas systématiquement aux autorités. Tout dépend de l’évolution du conflit et parfois le simple déplacement chez le notaire pousse la partie adverse à s’accommoder avant le passage en justice. Ces déclarations criminelles constituent des sources particulièrement intéressantes pour observer la psychologie, les perceptions et les interprétations de la violence des victimes et des agresseurs. Nous proposons ici d’étudier les stratégies discursives mises en œuvre lors de la passation d’une déclaration devant le notaire et sur ce qu’elles révèlent de la société qui les produit. En effet, ces témoignages constituent une véritable mise en scène de la violence, qui est instrumentalisée afin d’obtenir gain de cause lors d’un conflit. Comment les comparants s’y prennent-ils ? Quels sont les topoï les plus souvent utilisés ? Observe-t-on une évolution de ces discours entre le XVIIe et le XVIIIe siècle ? Cette analyse permettra de mettre en lumière la manière dont la société attribuait différents seuils de gravité à des actes violents, leurs circonstances aggravantes et comment ces représentations de la société étaient sciemment utilisées par les intervenants pour déconstruire la gravité de leurs actes. Enfin, étudier la violence et les discours des personnes impliquées permet également une meilleure compréhension de phénomènes sociaux que nous proposons de souligner, comme l’importance de l’honneur et sa place essentielle dans la société d’Ancien Régime.

In Bolivia 44 % of the people living in rural areas do not have reliable access to electric energy. This is due to a combination of unfavourable geography and the lack of economic resources to achieve the necessary infrastructure. In this context, the main goal of this study is to evaluate the economic and technical feasibility of micro-grids including photovoltaic panels (PV), batteries systems and the possible inclusion of diesel generators for off-grid applications. To that aim, a linear optimization model was developed within the Pyomo framework in order to optimize both the installed capacities and dispatch of the PV, battery and diesel sub-systems. The defined objective function is the net present cost. The exogenous inputs of the optimization are the typical demand and solar irradiation of a region of Bolivia in order to achieve results close to real Bolivian systems. Results indicate that due to the high levels of subvention to hydrocarbons, the PV and Li-Ion technology are not yet competitive with a diesel generator for the electrification of rural areas. On the other hand a sensitivity analysis is performed and proves that if the government decide to stop part of the subvention or shared it between conventional and non-conventional sources, the PV becomes competitive and the Li-Ion batteries enter the market around 2020.

BRAIN-TRAINS will be able to answer the transition involved in transportation in Belgium. To analyse the sustainability impact of rail freight intermodality in Belgium, the life cycle assessment methodology will be used. The rail freight system is divided in this paper into rail operation, rail equipment and rail infrastructure. This paper shows the methodology to calculate the transport emissions related with the energy consumption during the rail operation. [less ▲]

Recent advances in agent-based micro-simulation modelling have further underlined the importance of a thorough full synthetic population procedure to guarantee a correct characterization of the true population. We propose an integrated approach including Markov Chain Monte Carlo (MCMC) simulation and profiling based methods to catch the complexity and the diversity of agents of the true population through representative micro samples. The population synthesis method is capable of building the joint distribution of a given population with its corresponding marginal distributions (e.g. age, gender, socio-professional status etc.) using complete, partial conditional probabilities or both of them at the same time. Particularly, the estimation of socio-demographic variables and characterization of daily activity-travel patterns are included within the framework. Data stemming from the 2010 Belgian Household Daily Travel Survey (BELDAM) are used to calibrate the modelling framework. We illustrate that this framework catches in an efficient way the behavioral heterogeneity of travelers. Furthermore, we show that the proposed framework is adequately adapted to build large scale micro-simulation scenarios of transportation and urban systems. [less ▲]

Recent researches have stated the fast deployment of IPv6. It has been demonstrated that IPv6 grows much faster, being so more and more adopted by both Internet service providers but also by servers and end-hosts. In parallel, researches have been conducted to discover and assess the usage of MPLS tunnels. Indeed, recent developments in the ICMP protocol make certain categories of MPLS tunnels transparent to traceroute probing. However, these studies focus only on IPv4, where MPLS is strongly deployed. In this paper, we provide a first look at how MPLS is used under IPv6 networks using traceroute data collected by CAIDA. At first glance, we observe that the MPLS deployment and usage seem to greatly differ between IPv4 and IPv6, in particular in the way MPLS label stacks are used. While label stacks with at least two labels are marginal in IPv4 (and mostly correspond to a VPN usage), they are prevalent in IPv6. After a deeper analysis of the label stack typical content in IPv6, we show that such tunnels result from the use of 6PE. This is not really surprising since this mechanism was specifically designed to forward IPv6 traffic using MPLS tunnels through networks that are not fully IPv6 compliant. However, we show that it does not result from non dual-stack routers but rather from the absence of native IPv6 MPLS signaling protocols. Finally, we investigate a large Tier-1 network, Cogent, that stands out with an original set-up. [less ▲]

In the context of energy demand side management (EDSM) and heat storage in aquifers, the design and functioning of aquifer thermal energy storage (ATES) systems have strong interconnections with the geology of the site which may be complex and heterogeneous, making predictions difficult. In this context, we developed a subsurface monitoring methodology to better characterize heat transfer in the subsurface with the help of 4D electrical resistivity tomography (ERT), multiple hydrological measurements in wells, and a short-term heat storage experiment conducted for the purpose in a confined alluvial aquifer. Results clearly show the ability of ERT to delimit the thermal plume growth during injection, the diffusion and decrease of temperature during storage, and the decrease in size after heat recovery. Energy balance shows that up to 70% of the energy can be easily recovered with an adapted strategy in the context of DSM. Short-term heat storage in alluvial aquifer is efficient and ERT is a valuable tool to image and estimate the temperature distribution in the subsurface. [less ▲]

The international conference « encore l'architecture – encore la philosophie » is an initiative of the GERPHAU lab, research group for Philosophy, Architecture, Urban (Architecture School of Paris La Villette, UMR 7218 CNRS-Lavue), in partnership with Cité de l'architecture et du patrimoine, UMR-Lavue (Laboratoire Architecture, Ville, Urbanisme, Environnement) and philAU (a scientific thematic network : Philosophy, Architecture, Urban). This conference is the first ARENA conference (Architectural Research in Europe Network Association), a shared platform that aims to promote, support, develop and disseminate high-quality research in all fields of architecture in the widest sense. The network already includes researchers from leading European architecture schools. Synopsis. In Paris in 1987, a first event was held to celebrate the meeting of two disciplinary fields, entitled “Mesure pour mesure, architecture et philosophie”. Architects and philosophers were invited to discuss together how philosophy could capture better what determines architecture itself. Now, on the occasion of a new international conference, the GERPHAU Lab seeks to restate and refresh the question of the meeting of architecture and philosophy, by asking: what still remains today of our cross-over practices? ENCORE L'ARCHITECTURE, ENCORE LA PHILOSOPHIE. To build together these reflections about the future of our respective practices, why don't we hold to the hypothesis that our recent histories, in architecture as well as philosophy, could be written through the addition of a few prefixes? In linguistics, a prefix does not only serve the formation of a new word: it also regenerates the question of the meaning of the word. It is a discursive invention and its real strength lies in its ability to engage a new type of relationship with the world. Re-, alter-, eco-, co-, bio-, etc., these prefixes have clung to both our discourses as well as our disciplines. But in what way do they question the meaning of our practices? In archi-tecture as in philo-sophy, how do these successive re-definitions put the fundamentals into question, and how do they disturb their alleged unity inherited from Ancient Greece? And, moreover, how does the over-use of prefixes help us to understand what still makes sense in philosophy, or what still makes sense in architecture? The key issue of this conference, ‘Encore l'architecture, Encore la philosophie’, will be to trace backwards the stream of architectural and philosophical ideas through the thematic of the prefix as constituting a form of narrative. The conference will aim to trace the paths of their development, and other influencing factors, so as to return to those meetings between architecture and philosophy which already have oriented, re-oriented and sometimes dis-oriented our speech. It will be a meeting at which we invite participants to retell the story of our disciplines in order to grasp what it is still unique today about our practices. [less ▲]

A new Common Agricultural Policy was defined in 2013, with a new structure for direct payment. In Wallonia, the government implemented the following scheme: 30% for the green payment, 29.9% for the basic payment, 17% for the additional payment for the first 30 ha, 1.8% for young farmers and 21.3% for couple payments. Due to convergence, the mean support through direct payments will decline from 21,900 € in 2014 to 19,283 € in 2019. The number of losers will be equivalent to the number of gainers. Regions where cereals and sugar beet are produced will lose the most, where the region suitable for cattle raising will gain somewhat. There will be a better distribution of direct payments among farmers: the Gini index will decline from 0.55 to 0.49. The highest negative impact on income will occur for the specialties “green crops”, “crops and dairy cattle” and “crops and non-dairy cattle”: the least negative impact will be observed within the specialties “dairy cattle”, “meat cattle” and “dairy and meat cattle”. The reform will be more profitable for the farms from 30 to 50 ha and will mainly impact the largest farms. Finally, the CAP reform implemented in Wallonia guarantees a smooth evolution to 2020.

La théorie de la transition forestière lie l’évolution du couvert forestier au temps (Mather, 1992). Dans la première phase, le couvert forestier est très dense. Il diminue ensuite avec l’augmentation de la densité de population qui pratique la défriche pour la production agricole et utilise le bois pour répondre aux besoins en énergie et en bois d’œuvre. Dans un troisième temps, l’économie se spécialise, l’agriculture s’intensifie et est pratiquée sur les terres les plus productives et le rôle de l’écosystème forestier dans l’économie diminue. L’abandon des terres les moins productives permet la recolonisation forestière visible sur la courbe de transition. La présente étude tente d’identifier et de proposer des indicateurs d’occupation spatiale permettant, sur base d’images de télédétection, de prévoir la position réelle d’un site sur la courbe de transition forestière. Ensuite, l’étude des socio-écosystèmes en lien avec la transition forestière permet de démontrer l’impact de la diminution du couvert forestier sur le fonctionnement des sociétés humaines. Nous nous sommes penchés sur différents aspects caractérisant les activités des populations locales dans trois sites d’étude situés sur un gradient de déforestation en Afrique centrale tels que la composition de repas et l’origine des aliments. On observe que la déforestation induit une diminution des composants issus des activités fortement liées à l’écosystème telles que la chasse, la pêche ou la collecte au profit de l’agriculture et de l’élevage.

Using heat as an active tracer in different types of aquifers is a topic of increasing interest. In this study, we investigate the potential interest of using heat tracer tests for characterization of a shallow alluvial aquifer. A thermal tracer test was conducted in the alluvial aquifer of the Meuse River, Belgium. The tracing experiment consisted in simultaneously injecting heated water and a dye tracer in a piezometer and monitoring the evolution of groundwater temperature and tracer concentration in the recovery well and in monitoring wells. To get insights in the 3D characteristics of the heat transport mechanisms the space-filling arrangement of observation wells was used. The breakthrough curves measured in the recovery well showed that heat transfer in the alluvial aquifer is slower and more dispersive than solute transport. Recovery is very low for heat while in the same time it is measured as relatively high for the solute tracer. This is due to the fact that heat diffusion is larger than molecular diffusion, implying that exchange between groundwater and the porous medium matrix is far more significant for heat than for solute tracers. Temperature breakthrough curves in other piezometers are contrasted with what would be expected in an ideal layered aquifer. They reveal strongly unequal lateral and vertical components of the transport mechanisms. The observed complex behavior of the heat plume was explained by the groundwater flow gradient on the site and heterogeneities of hydraulic conductivity field. By using numerical model of heat and flow coupled with pilot points inverse approach main preferential paths were characterized. [less ▲]

Le voyage au centre de la Terre a été magistralement imaginé par Jules Verne en 1864 avant de devenir un véritable topos de la littérature populaire et de jeunesse. Sa postérité s’illustre dans les multiples déclinaisons de la terre creuse, recensées notamment par Guy Costes et Joseph Altairac dans leur bibliographie commentée en 2006. En quoi ce motif plus communément associé à une atemporalité (monde perdu, histoire secrète) ou à une régression temporelle (monde sauvage, vie des cavernes) intervient-il aussi dans une écriture de l’anticipation ? Chez Verne lui-même, il s’agit à la fois d’un voyage à rebours dans le temps, chaque strate parcourue correspondant à un recul historique, et d’une expédition scientifique déployant une technologie et des connaissances novatrices. Ce motif topique semble donc porteur d’une ambiguïté temporelle féconde. La communication proposera un parcours transversal dans le corpus d’anticipation francophone allant d’Ignis (1883) de Didier de Chousy qui traite de l’exploitation d’une nouvelle énergie géothermique, le « feu central de la Terre », jusqu’à Régis Messac dont La Cité des Asphyxiés (1937) dépeint un monde intra-terrestre dystopique. Les reprises de la terre creuse permettent d’éclairer l’importance des filiations génériques, des supports partagés et des formules éditoriales à succès, mais elles mettent aussi en évidence des œuvres atypiques, traduisant de manière spécifique le discours social et scientifique de leur époque. Si Verne, ses épigones et d’autres auteurs d’anticipation ont pu être tentés de réinvestir la terre creuse en fiction à un moment où sa réalité n’est plus perçue comme crédible dans le champ scientifique, c’est sans doute en raison de l’intrication particulièrement dense des disciplines concernées (géographie, géologie, paléontologie, sciences naturelles) et de l’importance des idéologies qui ont pu les croiser et les dynamiser : positivisme, hygiénisme, colonialisme, craintes écologiques. Cette communication voudrait montrer comment le motif fécond de la terre creuse, dans son évolution complexe du plausible à l’irréel, passe d’une croyance à une théorie scientifique avant de se développer en chronotope littéraire.

Fama and French risk premiums do not reliably estimate the magnitude of the size or book-to-market effects, inducing many researchers to inflate the number of factors. We object that controlling ex ante for noise in the estimation procedure enables to keep a parsimonious set of factors. We replace Fama and French’s independent rankings with the conditional ones introduced by Lambert and Hübner (2013). This alternative framework generates much stronger “turn-of-the-year” size and “through-the-year” book-to-market effects than conventionally documented. Furthermore, the factors deliver less specification errors when used to price portfolios, especially regarding the “small angels” (low size – high BTM stocks). [less ▲]

On the 13th March 2009, Belgium’s French Community (currently named the Wallonia-Brussels Federation (WBF)) parliament, adopted the “décret mémoire” (decree of remembrance). This deed shows Belgian public authorities’ will to mark their presence in the memorial field. The decree organizes the recognition and the financing of multiple actors and institutions by the authorities, through a structure and a hitherto unseen way of functioning. Among its activities, the decree organizes yearly calls for projects, whose recipients are non-profit-making organizations and educational institutions that are either organized or subsidised by the WBF. The organisation set in place by the decree of remembrance appears to be a “political use of the past”. That means that some past events are chosen and promoted to give meaning to the individual memory, in a collective intent. This way of doing comes from the political will to organize the representation of one common past, aiming to bring out themes that carry particular values. Consequently, is it possible to study the power that the decree actually gives to the public authorities? Does it allow them to constrain or to influence other actors of their memory field? If that is the case, how could it be possible to demonstrate it? We suggest trying to find an answer to these interrogations through a case study concerning the 2014 calls for projects of the year.

While the combination of warmer and drier mean climatic conditions can have severe impacts on ecosystems, extreme events like droughts or heat waves that break the gradual climate change can have more long-term consequences on ecosystem composition, functioning and carbon storage. Hence, it is essential to assess the changes in climatic variability and the changes in frequency of extreme events projected for the future. Ecosystems could not be in a condition to adapt to these new conditions and might be disrupted. Here, the process-based dynamic vegetation model CARAIB DVM was used to evaluate and analyze how future climate and extreme events will affect European ecosystems. To quantify the uncertainties in the climatic projections and in their potential impacts on ecosystems, the vegetation model was driven with the outputs of different regional climatic models (RCMs), nested in CMIP5 GCM projections for the EURO-CORDEX project. We used the ALADIN version 5.3 (Météo-France/CNRM) and other EURO-CORDEX RCMs. These climatic projections are at a high spatial resolution (0.11-degree, ~12 km). CARAIB simulations were performed across Europe over the historical period 1951-2005 and the future period 2006-2100 under RCP4.5 and RCP8.5 emission scenarios. We simulated a set of 99 individual species (47 herbs, 12 shrubs and 40 trees) representing the major European ecosystem flora. First, we analyzed the climatic variability simulated by the climatic models over the historical period and compared it with the observed climatic variability. None of these climatic models can reproduce accurately the present natural climatic variability. Then, to assess the risk of ecosystem disruption in the future and to identify the vulnerable areas in Europe, we created an index combining several CARAIB outputs: runoff, mean NPP, soil turnover, burned area, appearance and disappearance of species. We evaluated the severity of change projected for these variables (period 2071-2100) relative to their current variability (period 1961-1990). Mean changes were considered severe if they exceed observed variability. The highest values of the index were found in southern Europe, indicating that the amplitude of the expected ecosystem changes largely exceeds current interannual variability in this area. [less ▲]

Passive acoustics can offer inexpensive, non-invasive and no-destructive means of assessing temporal and spatial patterns in the distribution of individuals engaging in calling. In marine environments, passive acoustic recording methods can be used at depths not accessible to humans, independent of weather conditions, and for a long term. However, these studies have often restricted their investigations to the monitoring of one or two aquatic species. One reason of this loss of information is quite easy to explain: most of the sounds can be detected but cannot be identified. In many families, calling abilities are described in one or two species only although the descriptions of sound producing mechanisms have highlighted other members should be able to make sounds. Since 50 years, sounds were for example described in more or less 40 pomacentrid species but all the 392 species should be able to make sounds. This situation can be more complicated since some species are able to make different kinds of sounds according to the behavioural context. Some call characteristics can also be modulated according to the size in some species only. It shows an important amount of work has to be done to be able to understand the reef soundscape and to develop call recognition software system. [less ▲]

Organocobalt(III) with acetylacetonate ligands is the most representative example of R-Co bearing a weak C-Co bond that can release alkyl radicals under mild experimental conditions without requiring a photoactivation. The unique isolated specimen is a short oligo(vinyl acetate) end-capped by Co(acac)2. The high lability of the C-Co bond of this R-Co combined to the unique capacity of Co(acac)2 to reversibly trap alkyl radicals make this organocobalt unique for the precision synthesis of unprecedented polymers by the so-called Cobalt-Mediated Radical Polymerization (CMRP) technique. The growth of unstabilized and highly reactive growing radicals formed by the addition of R· to unconjugated olefins (vinyl esters, vinyl amides, vinyl imidazolium, vinyl chloride, ethylene) is controlled by the reversible formation of a weak C-Co bond at the polymer chain end. The lack of alternatives to this R-Co, especially to the structure of the alkyl group, has placed limitations on further innovation in (macro)molecular design. Other functional variants that would enable attractive chain-end derivatizations are unfortunately not available. In this communication, we will address this important challenge by describing an innovative synthetic route towards the preparation of a new functional R-Co(acac)2 that are characterized by a weak C-Co bond. We will report the conditions required for initiating and controlling the radical polymerization of various monomers from these R-Co. We will also demonstrate their utility for the production of novel telechelic polymers under mild experimental conditions, syntheses that can be carried out in water. [less ▲]

We report results from a study of nitric oxide nightglow over the northern hemisphere of Mars during winter and southern hemisphere during equinox. We present observations of the nitric oxide δ and γ band emissions between 190 and 270 nm by the Imaging UltraViolet Spectrograph on the MAVEN spacecraft. The emission reveals recombination of N and O atoms dissociated on the dayside of Mars, and is known to trace upper atmosphere hemispheric circulation patterns. We extend previous studies to higher latitudes, finding brighter emissions closer to the poles as predicted from global circulation models. Statistically significant variability suggests variation of the fluxes of N and O carried from the dayside thermosphere, as well as possible variations of the wind pattern in the nightside thermosphere and mesosphere.

Since a few years, it has become possible to observe the development of cyber parties in western democracies. Their intensive use of internet to coordinate relations between members is supposed to attract new types of militant, interested by less hierarchical informal networks and sporadic political activities. Yet, the following question remains: What role(s) does the Internet play in the enrolment process within this kind of parties? Analyzing fifteen in-depth interviews with Belgian Pirate Party’s members as well as members’ online activities, this paper shows that it is possible to distinguish two kinds of cyber parties’ members. On the one side, some members are passionate about information and communications technology and their party membership is their sole political activity. On the other side, some members are more distant users of the Internet and are active in plenty of postmodern political associations. These two divergent militant profiles are key elements to explain the divergence of views among Belgian Pirate Party’s members, but also the relative lack of political visibility of this political party due to difficulties in achieving coordination.

Comment les différents acteurs chargés de leur application – juges civils/de paix, médecins, avocats, assureurs, syndicats – autant que les victimes ont-ils expérimenté ce nouveau cadre légal ? Par un retour prioritaire aux sources judiciaires, cette contribution entend explorer ce processus d’apprentissage en mettant l’accent sur les principales difficultés rencontrées, sur les enjeux nouveaux et sur les réponses apportées au cours des années d’entrée en vigueur de la loi. À titre comparatif, les mêmes types de sources seront examinées pour une période tenue pour plus routinière (c. 1928-1930), de manière à mettre en évidence certaines des solutions retenues après la phase d’apprentissage, tout en soulignant, le cas échéant, les problèmes pendants ou nouveaux.

This paper aims to design an algorithm dedicated to operational planning for microgrids in the challenging case where the scenarios of production and consumption are not known in advance. Using expert knowledge obtained from solving a family of linear programs, we build a learning set for training a decision-making agent. The empirical performances in terms of Levelized Energy Cost (LEC) of the obtained agent are compared to the expert performances obtained in the case where the scenarios are known in advance. Preliminary results are promising. [less ▲]

Pumped Storage Hydroelectricity (PSH) is a good alternative to increase the efficiency of power plants, which cannot regulate the amount of electricity generated according to the demand (wind, solar or even nuclear power plants). PSH plants, which consist in two reservoirs located at different heights (upper and lower), can store energy during low demand periods (pumping water from the lower to the upper reservoir) and generate electricity during the high demand peaks (falling water from the upper to the lower reservoir). Given that the two reservoirs must be located at different heights, PSH plants cannot be constructed in flat regions. Nevertheless, in these regions, an alternative could be to use abandoned underground works (open pits or deep mines) as lower reservoirs to construct Underground Pumped Storage Hydroelectricity (UPSH) plants. To select the best place to construct a plant, two considerations must be taken into account regarding the interaction between UPSH plants and groundwater: 1) the alteration of the natural conditions of aquifers and 2), the efficiency of the plant since the electricity generated depends on the hydraulic head inside the underground reservoir. Obviously, a detailed numerical model must be necessary before to select a location. However, a screening methodology to reject the most disadvantageous sites in a short period of time would be useful. Groundwater flow impacts caused by UPSH plants are analyzed numerically and the main variables involved in the groundwater evolution are identified. The most noticeable effect consists in an oscillation of the groundwater. The hydraulic head around which groundwater oscillates, the magnitude of the oscillations and the time to achieve a “dynamic steady state” depend on the boundaries, the parameters of the aquifer and the characteristics of the underground reservoir. A screening methodology is proposed to assess the main impacts caused in aquifers by UPSH plants. Finally, the efficiency regarding the groundwater evolution inside the reservoir is determined.

Power can be performed by a system driven by a potential difference. From a given potential difference, the power that can be subtracted is constraint by the Carnot limit, which follows from the first and second laws of thermodynamics. If the system is such that the flux producing power (with power being the flux times its driving potential difference) also influences the potential difference, a maximum in power can be obtained as a result of the trade-off between the flux and the potential difference. This is referred to as the maximum power principle. It has already been shown that the atmosphere operates close to this maximum power limit when it comes to heat transport from the Equator to the poles, or vertically, from the surface to the atmospheric boundary layer. To reach this state of maximum power, the effective thermal conductivity of the atmosphere is adapted by the creation of convection cells. The aim of this study is to test if the soil’s effective hydraulic conductivity also adapts in such a way that it produces maximum power. However, the soil’s hydraulic conductivity adapts differently; for example by the creation of preferential flow paths. Here, this process is simulated in a lab experiment, which focuses on preferential flow paths created by piping. In the lab, we created a hydrological analogue to the atmospheric model dealing with heat transport between Equator and poles, with the aim to test if the effective hydraulic conductivity of the sand bed can be predicted with the maximum power principle. The experimental setup consists of two freely draining reservoir connected with each other by a confined aquifer. By adding water to only one reservoir, a potential difference will build up until a steady state is reached. The results will indicate whether the maximum power principle does apply for groundwater flow and how it should be applied. Because of the different way of adaptation of flow conductivity, the results differ from that of the atmosphere. [less ▲]

In the context of energy demand side management (DSM), energy storage solutions are needed to stock energy during high production periods and recover energy during high demand periods. Among currently studied solutions, storing energy in the subsurface through heat pumps and/or exchangers (thermal energy storage) is relatively simple with low investment costs. However, the design and functioning of such systems have strong interconnections with the geology of the site which may be complex and heterogeneous, making predictions difficult. In this context, local temperature measurements are necessary but not sufficient to model heat flow and transport in the subsurface. Electrical resistivity tomography (ERT) provides spatially distributed information on the temperature distribution in the subsurface. In this study, we monitored, with 4D ERT combined with multiple hydrological measurements in available wells, a short-term heat storage experiment in a confined alluvial aquifer. We injected heated water (ΔT=30K) during 6 hours with a rate of 3 m³/h, stored during 3 days, and then we pumped it back to estimate the energy balance. We collected ERT data sets using 9 parallel profiles of 21 electrodes and cross-lines measurements. Inversion results clearly show the ability of ERT to delimit the thermal plume growth during injection, the diffusion and decrease of temperature during storage, and the decrease in size after pumping. Quantitative interpretation of ERT is difficult at this stage due to strong spatial variations of the total dissolved solid content in the aquifer, due to historical chloride contamination of the site. Energy balance shows that up to 75% of the energy can be easily recovered with an adapted strategy in the context of DSM. Short-term heat storage in alluvial aquifer is efficient and ERT is a valuable tool to image and estimate the temperature distribution in the subsurface. [less ▲]

With unprecedented speed and extent, the future climate change can be expected to severely impact terrestrial ecosystems due to more frequent extreme events, such as droughts or heat waves. What will be the impacts of these extreme events on ecosystem functioning and structure? How far will net primary production be reduced by such events? What will be the impact on plant mortality? Could such events trigger changes in the abundance of plant species, thus leading to biome shifts? In this contribution, we propose to use ISI-MIP2 model historical simulations from the biome sector to analyse the response of ecosystems to droughts or heat waves, trying to understand the differences between several vegetation models (e.g. CARAIB, HYBRID, LPJ). The analysis will focus on Europe. It will compare and assess the model responses for a series of well-marked drought or heat wave events in the simulated historical period, such as those that occurred in 1976, 2003 or 2010. This analysis will be performed in terms of several important environmental variables, like soil water and hydric stress, runoff, PFT abundance, net primary productivity and biomass, fire frequency, turnover of soil organic matter, etc. Whenever possible, the response of the model will be compared to available data for the most recent well-marked events. Examples of data to be used are eddy covariance, satellite data (including leaf area and fire occurrence) or tree rings. [less ▲]

Distinguishing the analysis of spatial data from classical analysis is only meaningful if the spatial components bring information. Therefore, testing if the spatial autocorrelation is significant may confirm or deny the need to consider spatial analysis over the classical one. Spatial autocorrelation expresses the dependence between values at neighbouring locations. Several measures of spatial autocorrelation are defined in the literature. Moran’s index, Geary’s ratio and Getis-Ord statistic are the most used statistics. Tests based on these measures have been developed in the literature using asymptotic and permutation results. They are used in practice in many fields, for instance in geography, economics, biogeosciences, medicine, ... However, these tests should be cautiously applied because they are not robust. A single contaminated observation can significantly modify their results. The talk has two main objectives. Firstly, the already available tools for measuring spatial autocorrelation will be reviewed with an emphasis on the study and comparison of their robustness. Secondly, alternative methods will be proposed to robustly estimate the spatial autocorrelation. [less ▲]

Various (inter)national organizations and institutions expend a great deal of effort on fighting against the dramatic grow of the sedentariness of the modern society. In consumer magazines as well as in prestigious scientific journals, number of publications emphasize the interest that each of us can withdraw from a regular active lifestyle. So, nowadays, in the Western countries, everyone is supposed to know that physical activity is one of the ingredients of a healthy lifestyle. Nevertheless, it is clear that the population seems to paradoxically misunderstand the concept of physical activity. Moreover, in terms of sedentariness, the female audience is considered as particularly at risk and requires specific attention. According to the socioecological models, physical activity behaviors are influenced by a large array of variables belonging to the person itself as well as for its social, built, natural environments, and policies. In parallel, the transtheoretical model of health behavior change emphasizes that a person who changes his/her behavior goes through five stages (precontemplation, contemplation, preparation, action, and maintenance). Following that theory, the starting point of the change process consists of the awareness of the individual about the behavior. This stage refers to the individual factors linked to psychological, cognitive and emotional aspects (knowledge about PA, expected benefits, motivation, perceived pleasure …) that can be related to the people’s representations about PA. A representation can be defined as a mental phenomenon that corresponds to a more or less conscientious, organized and consistent set of cognitive and affective elements concerning one particular object. The goal of this paper is to underline the interest of the analysis of the representations about PA in a way to understand the reasons of reluctance, motivation and/or blockages demonstrated by individuals - and by women in particular - in their changing process. Study on such topic could become a key aspect in the search for useful tools in the habits transformation. In fact, despite representations’ central role, very few studies focusing on this variable have been published in the literature. This is especially surprising as it was demonstrated that representations about PA have a bigger influence on the lifestyle modification than concrete environmental variables do. When considering representations about PA, we consider five elements: definition, believes about the impacts, knowledge of the recommendations, self-evaluation, and identification of the change strategies). These questions will be the focus of the paper. Data will support and illustrate their legitimacy in the physical activity promotion. [less ▲]

The univariate coefficient of variation (CV) is a widely used measure to compare the relative dispersion of a variable in several populations. When the comparison is based on $p$ characteristics however, side-by-side comparison of marginal CV's may lead to contradictions. Several multivariate coefficients of variation (MCV) have been introduced and used in the literature but, so far, their properties have not been much studied. Based on one of them, i.e. the inverse of the Mahalanobis distance between the mean and the origin, this talk intends to demonstrate the usefulness of MCV's in several domains (finance and analytical chemistry) as well as provide a complete inference toolbox for practitioners. Some exact and approximate confidence intervals are constructed, whose performance is analyzed through simulations. Several bias-correction methods, either parametric or not, are suggested and compared. Finally, since MCV's are used for comparison purposes, some test statistics are proposed for the homogeneity of MCV's in $K$ populations. Throughout the talk, the robustness of the techniques will be discussed. As a by-product, a test statistic allowing to reliably compare $K$ univariate CV's even in presence of outliers will be outlined. [less ▲]

Ethane is the most abundant non-methane hydrocarbon in the Earth's atmosphere and an important precursor of tropospheric ozone. Its monitoring is therefore crucial for the characterization of air quality and of the transport of tropospheric pollution. Ethane is also an indirect greenhouse gas, influencing the atmospheric lifetime of methane. The main sources of ethane are located in the northern hemisphere, and the dominating emissions are associated to production and transport of natural gas. A preliminary trend analysis was conducted using measurements performed in the Swiss Alps. Over the last two decades, the trend of ethane showed a decline of around 1% per year, thanks to a reduction of fugitive emissions of fossil fuel sources. However, a recent upturn potentially attributed to the massive exploitation of shale gas and tight oil reservoirs in North America was found. The goal is to investigate the presence and form of changes in trend functions using nonparametric techniques. The possible location of such changes is investigated. In addition, nonparametric estimation techniques are used to allow for nonlinear trend functions. Given the nonstandard nature of the measurements we rely on dependent wild bootstrap techniques to conduct inference on possible breaks in linear trends and on nonparametric trend functions.

The Sahelian's environment suffered many perturbations increasing the food insecurity risks. Since three decades, the environment suffered a intense and significant land deterioration (Warren A. And al., 2001). A lot of regreening actions have been developped in the Sahelian countries but some actions are most sustainable and the costs are lower than the other. The International Fund for Agricultural Development (IFAD) has developped some actions to strengthen the natural ressources management. The most important actions have been introduced from the mi-term of 1,980 (Sendzimir J. And al., 2011). These actions concerned the main water and soil conservation technics: Zaï; „contour“ stone bund; half-moons; permeable rock dams (Wesel A., Rath T., 2002). The paper attempts to answer about the following question: „what are the indirect and direct socioeconomic impacts of the natural ressources management in the Maradi’s region ?“. Moreover, Maradi is the historical area of the IFAD actions and illustrates some major causes of land degradation. The main causes are the increase of demography and agricultural areas. In fact, the demography and agricultural area of Maradi are seriously worrying: 8 children per women and the agricultural area is less than 1 hectare per household (Andres L., Lebailly Ph., 2013). The paper relates and describes the main anti-erosion technics. It compared also the cost-benefit analysis about the soil and water conservation technics. Finally, the report try to establish a key who links the technics with the context (soil, people, environment, agriculture, livestock) (Moussa Dit Kalamou M., 2015; Jasmien C.J. and al., 2013).

That gave us a large amount of data about this period of Neanderthal history. We now questioning about the choice of this locality and the spatial organisation of Neanderthal. Then, spatial analysis using the Geographic Information System (GIS) appear to being a useful tool to answer it. We show the consequent availability of water, prey and tool raw material.

Au départ des études sur la culture matérielle, le lien entre les choses et les sujets, établi par le biais du corps, sera exploré. La consommation, en tant que moyen d’incorporation des objets dans le soi et dans son propre univers de référence, constituera la porte d’entrée de l’analyse de ce lien. De l’élaboration des choix à la dé-marchandisation des produits, le processus qui engage simultanément choses et sujets jette les bases de la définition individuelle et des relations sociales. L’alimentation en est un exemple concret. Pratique qui stimule la réceptivité multidimensionnelle du corps, elle permet également de s’interroger sur le rôle de celui-ci non seulement dans les dynamiques de consommation mais aussi dans les démarches ethnographiques visant leur compréhension.

This research analyzes the gender dimensions of labor migration and agricultural production among farm households in Red River Delta region of Vietnam. Through surveying 215 households in Bac Ninh province, the paper explores impacts of female and male migration on agricultural production and its implications on rural development. The results show that in comparison to male migration household, the female one tends to focus on agricultural production by taking the opportunities to rent more land (26.3%) and effective use their own allocated land for agricultural production (97.4%). The overall impacts of migration on agricultural production are the aging of farm labor force (49.6 year old in average) and higher female participation in agricultural production. The findings suggest that female migrants have a greater contribution in agriculture production both in term of working time and agricultural capital investment while male migrants enhance household income by accumulating capital outside agriculture. Through the gender lens, this research emphasizes the duality in the nature of migrant lives and the implications of rural labor migration on the fixed categories. [less ▲]
