Les origines savantes ou populaires des épopées françaises médiévales ont longtemps fait débat. Il s'avère que ces textes contiennent un très grand nombre de références à des personnages issus de l’Antiquité qui témoignent d’une formation scolaire chez les auteurs des chansons. Sur la base d'un examen de l'ensemble du corpus, cette étude s'intéresse plus particulièrement aux mentions explicites faites à des auteurs antiques, qu'ils soient grecs (Homère, Aristote, Platon) ou latins (Virgile, Ovide, César, Caton, Sénèque). En tenant de déterminer les traditions qui ont pu nourrir l'inspiration des auteurs des chansons de geste, elle s'emploie à définir les situations dans lesquelles les références en question apparaissent, et s’interroge sur les finalités que poursuivent les poètes à travers l’évocation des auteurs antiques, dont certains, comme César ou Virgile, sont davantage restés dans les mémoires pour des éléments réels ou imaginaires de leur vie plutôt que pour leur œuvre.

This communication aims at assessing the bias introduced by the use of the Euclidean distance in the context of geographic profiling analyzes. It proceeds by a comparison of road and Euclidean distances of about 1 000 pairs of origin-destination (crime sites – criminal’s anchor point) from the database of the Belgian Federal Police. Comparisons are differentiated by the density of road network (rural and urban areas) and the statistical parameters of the resulting distributions are exploited in the application of the most common geographic profiling model called the distance decay model.

We revisit the limit on very light axion-like particles (ALPs) from the absence of gamma rays coincidental with the neutrino burst from SN1987A. We use updated supernova simulations, modern models for the magnetic field inside the Galaxy, and a Primakoff cross section which takes into account proton-degeneracy and mass-reduction effects. We finally give an updated exclusion plot for the electromagnetic coupling of sub-eV ALPs, comparing our new bound with other limits as well as with future ALP searches. [less ▲]

Bernardo Dovizi, one of the most famous secretaries of the early Italian Reinassance, is best known for his literary works and for being the patron of Raffaello rather than for his endeavors in diplomacy. By deciding to follow the interests of Giovanni de’ Medici, Dovizi made some poor political decisions in his career but, in spite of this, he cunningly managed to get his patron become the Pope. The "Calandra" is a work that depicts well the author’s ideas, in between parody and classicism. From his works, Epistolario and Ricordi, it appears that the main strength of Dovizi is his irony, through which he manages to become almost an accomplice with his patron. Alongside with the iconological choice of the frescoes of his Stufetta and Loggia in the Vatican, he assumes the posture of the secretary-jester, as it was portrayed by Baldassarre Castiglione in "The Book of the Courtier": the satyr that washes into the room, used as bathroom, corresponds to the most famous pose of the patron who insists on these burlesque and mocking characteristics, although relating to Ovid and Plato. Bibbiena seems to be aware of how much the man that exceeds in praise himself appears unbearable, therefore, in his relations with members of the ruling class, he often assumes a playful attitude. In the Rome of Leo X, because of the Socratic 'serio ludere', such attitude was accepted and admired. The best instruments of Bibbiena are the pleasantness and a careful selection of humanistic ideals. Such ideals were those that suited better the environment in which he, the courtier, had to operate, and were used in his works. [less ▲]

The different steps of the foraging process of wireworms (Coleoptera: Elateridae) would be better understood if accurate and holistic information regarding the role of plant-produced chemicals constituting their environment were available. Volatile organic compounds (VOC) play important roles in the interactions between plants and insects in many ecosystems, whether they take place aboveground or belowground. The roles of VOC are still relatively unknown for wireworms, and deserve attention. Here, we performed three experimentations with barley roots as baits. In the two first, we assessed the effect of chopped roots and fungus infected roots on the orientation of wireworms. In the third experiment, the larvae were confronted to both healthy and fungus infected roots. We discuss the results in terms of suitability of the olfactometers we designed for the investigation of olfaction in wireworms, and we provide suggestions to improve their use. [less ▲]

Science and technology require an intervention by the law, and law is called upon to intervene in front of their evolution, and to look for proper solutions of governance and rational responses to their risks. One of the main issues to be investigated from the legal viewpoint is represented by the ‘dual-use dilemma’ that arises both in ‘traditional’ and new areas of techno-sciences. Indeed, any kind of research has the potential to be used both for bad as well as for good purposes. Therefore, it is important to reflect upon the ways to control possibly dangerous research without preventing the progress from going further. Such ‘dual-use dilemma’, then, entails the study of one of the fundamental freedoms in the biolaw area: the freedom of scientific research, its limits, and relationship with other rights/needs/freedoms (such the need of security). This work focuses on two areas of the techno-scientific world. One is more ‘traditional’, i.e. nuclear science, in whose context the reflections on ‘dual-use’ were born and developed, and the other one is a new emerging technology, which is synthetic biology. The aim is to understand how the freedom of scientific research could be shaped in relationship with other rights/needs/interests for dealing with ‘dual-use’ issues in the aforementioned areas of science and technology.

L’aménagement transsexuel comme solution à l’adolescence La transsexualité est souvent banalisée par les médias, séduits par l’idée facile à vendre d’une âme sexuée, donc du drame de la possible inadéquation entre le sexe psychique et le sexe corporel. L’observation clinique rigoureuse de son élaboration plaide cependant pour une architecture complexe, résultant d’une dynamique subtile entre le psychisme, l’histoire et l’environnement. En effet, dans l’analyse d’un cas clinique, nous constatons que, face au risque de l’effondrement identitaire d’une structure fragile le Moi tente de se renforcer par l’organisation de mécanismes de défense qui élabore une nouvelle identité étayée sur un physique transité vers l’autre sexe. Si l’on analyse les interactions précoces sous l’angle de la formation de l’identité sexuelle, le noyau « genré » du Moi peut subir une double attaque, par manque d’identification au même et par attaque mortifère du différent. Le Moi se trouve ainsi délié et persécuté par des objets partiels ou peu introjectés. A l’adolescence, moment potentiellement traumatique de la sexuation, le jeune se trouve confronté à l’interrogation sur son identité sexuelle, et lorsque le noyau « genré » s’est précisément trouvé fragilisé, l’angoisse surgit, avec le risque d’une bascule psychotique. Dans ces cas extrêmes, la recherche d’une nouvelle enveloppe, remodelage de la peau, permet de contenir l’éclosion du courant psychotique grâce à la disponibilité permanente de l’incorporation du différent, identification certes coûteuse en ressources mais peut-être, à même d’éviter l’effondrement narcissique complet.

Blattmasken belong to vegetalized human figures used in parietal decoration of nymphaei and domestic ponds. Their use depends on the process of iconographic forms’ transmission already highlighted between the parietal mosaic, the italic mural painting of Ist century a.C. and the African ground mosaic. This transfer is discussed in the light of two cases : the House of Neptune and Amphitrite at Herculanum and the House of the Nymphs at Neapolis. The study is based on their iconographical environments and on their typology. It highlights two different symbolic conceptions of the motive. [less ▲]

Solar-like oscillations have now been characterized for a large number of stars, thanks to asteroseismic data obtained recently by space missions. This has led to the determination of the global and internal properties of these stars. In particular, core rotation rates have been obtained for red-giant stars, which is of prime importance to progress in the modelling of the dynamical processes at work in stellar interiors. In this presentation, we discuss which constraints can be brought by these asteroseismic measurements on stellar models that include rotational effects. Similarly to the solar case, we show that an efficient mechanism is required for the transport of angular momentum in the radiative zones of red giants. The efficiency of this transport process can be determined by asteroseismic observations of red-giant stars. [less ▲]

Fixité et mouvement coexistent fréquemment dans l’imagerie antique. Les Blattmasken en sont la parfaite illustration, car ils se caractérisent à la fois par une frontalité presque exemplaire et par un dynamisme végétal insufflé par les feuilles dont ils sont composés. Les quatre exemples choisis pour illustrer ce propos correspondent chacun à une formule particulière d’intégration des têtes végétalisées dans leur environnement immédiat. Celles-ci peuvent en effet être isolées de tout contexte végétal, intégrées dans un décor de rinceaux, ou encore structurellement liées à celui-ci en lui donnant naissance ou en émergeant de l’une de ses volutes. Cette forme de végétalisation de la figure humaine semble se rattacher à une hybridation plutôt qu’à une métamorphose. Cette fusion des règnes humain et végétal révèle une symbolique complexe qu’il conviendra de préciser. [less ▲]

Video games have become more and more complex over the past decades. Today, players wander in visually and option- rich environments, and each choice they make, at any given time, can have a combinatorial number of consequences. However, modern artificial intelligence is still usually hard-coded, and as the game environments become increasingly complex, this hard-coding becomes exponentially difficult. Recent research works started to let video game autonomous agents learn instead of being taught, which makes them more intelligent. This contribution falls under this very perspective, as it aims to develop a framework for the generic design of autonomous agents for large-scale video games. We consider a class of games for which expert knowledge is available to define a state quality function that gives how close an agent is from its objective. The decision making policy is based on a confidence measurement on the growth of the state quality function, computed by a supervised learning classification model. Additionally, no stratagems aiming to reduce the action space are used. As a proof of concept, we tested this simple approach on the collectible card game Hearthstone and obtained encouraging results. [less ▲]

Insults, gossip, and slander are the origin of many conflicts during the Ancien Régime. They are used to hurt someone’s honour or reputation, which are essential values to keeping good relationships in society. People need to defend their honour when they are injured. They can seek reparations by taking legal action or opting for infrajudicial practices, such as contacting a notary. This possibility has attracted too little attention from historians whereas notarial records are a massive source of information related to conflicts affecting people's daily lives. Indeed, during the eighteenth century, inhabitants of Liège contacted a notary in order to find an agreement, clear their name of an insult, or to write their version of an aggression. [less ▲]

Ad una prima lettura l’epistolario di Sebastiano Erizzo si distingue per la centralità di alcune tematiche che stanno a cuore all’autore, cioè la letteratura, la numismatica e la filosofia, tutte discipline riconducibili all’amore per l’antichità, per la storia romana e per il pensiero greco, e passioni che l’antiquario veneziano coltivò per tutta la sua vita. Questo saggio ha l’intento di delineare alcuni snodi tematici che l’epistolario mette in luce e si soffermerà su un ambito prettamente letterario che investe gran parte della produzione erizziana, vale a dire il discorso sul genere e sull’ultima sezione dell’opera, contenente le Amorose.

Ce texte entend réévaluer l'idée de "pure synthèse intellectuelle" que l'on trouve chez Kant. Celle-ci cadre avec la pratique mathématique et métamathématique postérieure à Kant. Elle permet de dépasser l'alternative entre l'intuitionnisme développé dans la Critique de la raison pure et la fondation de la mathématique sur une logique formelle analytique. Je montre que cette idée convient à Bolzano et à Dedekind, dont je soutiens que les projets sont irréductibles à du logicisme et qui sont dès lors bien plus "kantiens" qu'il n'y paraît. [less ▲]

Inséparable du processus d'autonomisation du discours poétique et de la radicalisation que ce processus connaît chez lui, sur fond de propagande wagnérienne et de propagation du vers libre, le modèle musical prend, dans l'esthétique de Mallarmé, l'aspect d'un système de rapports généralisés à tous les paramètres de l'écrit. L'inhérence réciproque que le poète établit entre la "Musique" et les "Lettres", représentation imaginaire dont Un Coup de dés constitue la contrepartie réalisée, répond d'un côté à un matérialisme de la forme et de l'autre à un idéalisme fictif, voulant que les structures verbales et prosodiques s'offrent en miroir du système de rapports avec quoi se confond, en sa finitude sans extériorité, l’univers même.

Chacun sait que chez les anciens Grecs, Crésus passait pour un roi richissime à la tête d’un des plus puissants royaumes de son temps. En apportaient la preuve ses nombreuses offrandes consacrées au sanctuaire de Delphes, visibles de tous. L’épisode de sa mort sur un bûcher, un des moments les plus dramatiques de son existence, fut évoqué par nombre d’auteurs anciens et elle a fait l’objet de représentations figurées tout au long de l’Antiquité. Enfin, il ne faut pas oublier que pour un Grec du VIe siècle, l’homme passait pour constituer comme un rempart infranchissable protégeant les cités grecques de la côte d’Asie Mineure contre la puissance montante des Perses de Cyrus II le Grand. Ainsi la défaite inattendue du roi lydien face aux troupes perses en Ptérie constitue-t-elle un épisode décisif de l’époque archaïque grecque dans la mesure où elle signe la fin prochaine du royaume lydien et de son formidable maître. Les cités grecques d’Asie Mineure allaient vite devoir face à leur destin : une soumission aux Perses puis leur révolte entraînant les terribles guerres médiques. Dans notre exposé, on mettra l’accent sur les causes de cette bataille décisive perdue par Crésus à Ptérie, sur son déroulement et ses enjeux à la lumière des sources à notre disposition. On sera amené à analyser le tracé de la Route royale empruntée par le dernier descendant de Gygès pour se rendre en Cappadoce ; on aura ainsi l’occasion de voir que son existence est bien antérieure à l’arrivée des Perses en Anatolie occidentale. Enfin notre exposé présentera la localisation exacte de la ville de Ptérie, une question débattue depuis longtemps mais que des fouilles archéologiques récentes ont permis d’éclairer. [less ▲]

Syntactic analyses describe grouping operations that explain how words are combined to form utterances. The nature of these operations depends on the approach. In a constituency-based approach, grouping operations are ordered, or stratified, part-whole relations. In a dependency-based approach, grouping operations identify a governor (or head), i.e. they are directed hierarchical relations between words. It is possible to convert a constituency tree into a dependency tree by dereifying the nodes, by identifying the governor and by removing the stratification of the part-whole relations. Polygraphs combine the two types of information into a single structure and are therefore a more powerful formalism. By relaxing constraints, polygraphs also allow to underspecify both kinds of information. [less ▲]

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.

In the dual context of increased Central and Eastern European migration and of the global financial and economic crisis, several Northern European Member States have implemented (or debated) reforms of their welfare regimes to restrict access to migrants coming from other EU Member States. As the debates on the so-called “welfare tourism” are intensifying in different parts of the EU, we can observe a growing trend among Member States to use welfare policies as instruments to limit the mobility of certain EU migrants. This stance is best illustrated with Prime Minister Cameron’s demand for four-year ban on EU migrants claiming in-work benefits. In Belgium, too, EU citizens have been particularly affected by this adverse context as the Migration Office (Office des Etrangers) has intensified controls against EU residents receiving welfare benefits. With this policy, authorities have been using a restrictive interpretation of the European Directive 2004/38 that allows Member States to remove residence permits from EU citizens who represent an “unreasonable burden on state finances”. As a consequence, the number of EU citizens expelled from Belgium on a yearly basis has jumped from 343 to 2,042 between 2010 and 2014. In this paper, we propose to focus on those EU citizens who see their freedom of circulation in the EU restricted after claiming social protection in their country of residence. Relying on fieldwork conducted with Italian and Romanian migrants who experienced the removal of their residence permit, we discuss the different resilience strategies of those EU citizens faced with the legal obligation to leave: such strategies include returning to the homeland, refusing to leave, mobilizing the support of migrant organizations, introducing individual appeals, and seeking to regularize their administrative status. In particular, we shall focus on the experience of EU migrants who have decided to stay in Belgium and experience the status of an undocumented EU migrant. This peculiarity of this status is visible in three respects: 1) expulsion is not enforced by local authorities, 2) migrants continue to be able to circulate between their homeland and the country where they no longer have a residence permit, and 3) they have a possibility to regularize their status if they can demonstrate to municipal authorities that they no longer represent “a burden” on Belgium’s public finances. Overall, confronting our data to the rich literature on undocumented third country nationals, we discuss the limits of EU citizenship as experienced by those who are denied the right to free movement. This paper relies primarily on multi-sited ethnographic fieldwork (in progress) conducted with Italian and Romanian migrants in Brussels and with individuals of the same nationality who decided to leave Belgium and return to their home country after the removal of their residence permit. Additional fieldwork includes semi-directed interviews with civil society organizations, trade unions, and consular authorities. The data collection process started in May 2014 and is expected to be finished in May 2016. [less ▲]

n the first volume of his Mythologiques, entitled The Raw and the Cooked, Claude Lévi-Strauss argued that the preparation of food is a form of language that reveals a society's structure. For Lévi-Strauss, the so-called culinary triangle of the raw, the rotten and the cooked represents a semantic field within which the various forms of transformation of food from nature into culture play a key role. Since Lévi-Strauss, following extensive changes to food production, preparation and consumption, the notion of cooking has become ever more diversified, and became increasingly contentious. Yet, the multiple ways of combining and processing ingredients still give social and cultural meanings to food and trigger the creation of sociabilities and belongings through its own destruction (Gell 1986). This panel aims to explore Levi-Strauss' legacy and evaluate its usefulness in today's context from different angles, ranging from domestic food preparation to industrial production and global circulations of food. To what extent can this concept still provide an interpretative framework of topical food issues? Which contemporary myths does it shed light on? How could it be deployed to read the history of food and link it to contemporary questions? This panel welcomes papers on the history of food preparation, contemporary food preparation, including debates in professional and multimedia circles, various forms of food production and the possible transformation of food within globalised food markets. Although mobilizing a classic anthropological theory, this panel aims to be interdisciplinary and to present a diverse range of analytical perspectives. [less ▲]

Recently, companies are forming strong relationships with their strategic suppliers and customers in order to maximize their profit in the global market. Such a partnership or strategic alliance is based on the mutual needs of both parties. A partnership network is formed by different strategic firms (e.g., suppliers, manufacturers, distributors, retailers) who intend to establish strong relationships together but without losing their ownership, power and control on the firm. For example, if supplier X has a strong relationship with customer Y and Y has a strong relationship with supplier Z, then X, Y and Z can form a partnership network with three nodes (X, Y and Z) and two edges (X ->Y and Z->Y). In this paper, we develop a statistical methods to study the normal behaviour of partnership networks. We furthermore develop a methodology that will help diagnose the nature of identified unusual network behavior. [less ▲]

The Bor Basin is located in the east part of the Konya-Ereğli Plain occupied by Pleistocene lake (Fig. 1). Paleo-shoreline deposits rising western margins of the basin marked the former extent of a now desiccated Late Pleistocene Lake. This study evaluates the former lake level changes and the sequential evolution of a shoreline system that developed at the western margin with lacustrine fills of the Bor paleolake near Zengen settlement. The fills belongs to alluvial fans formed by streams coming from the high volcanic mountains located within the northern part of the basin. The sediment sequence of the fan reflects receded and extended levels of the former lake. 23 samples were obtained at the sand-quarry representing of various facies of the lacustrine fills. These samples were analyzed for mineralogical characterization, using XRD and their CaCO3 values were quantified. According to analysis, three evident different phases of weathering were distinguished in this deposit (Fig. 2). Weathering conditions occurred at the bottom of the profile (level 7) with the appearance of the vermiculite and illite/smectite mixed layer clays. Aridification phases occurred at the level of sample 16 with the appearance of the palygorskite. At the shallow levels from the samples 21 to 22, another aridification phase occurred attested by the appearance of the palygorskite, the mixed layers clays (illite/smectite) and the neoformation of the chlorite by weathering. The palygorskite occurrence showed only in the clay fraction (<2µm) associated with dolomite levels which support its secondary formation during dry periods and pedogenetic transformation. Pedogenesis conditions were attested also by the presence of the mixed layers clays at those levels. [less ▲]

The Moulouya has the largest catchment in Morocco and drains an area which is characterized by active crustal deformation during the Late Cenozoic due to the convergence between the African and Eurasian plates. As yet, its Pleistocene terrace sequence remains poorly documented. Our study focuses on the lowermost reach of the river in NE Morocco, which drains the Triffa sedimentary basin directly upstream of the estuary. New field observations, measurements and sedimentological data reveal contrasted fluvial environments on either side of a newly identified thrust zone, which disrupts the whole sedimentary basin and is associated with N–S compressive shortening in this region. Long-lasting fluvial aggradation, materialized by ≥37 m-thick stacked fill terraces, and the development of a well-preserved terrace staircase, with (at least) three Pleistocene terrace levels, occur in the footwall and the hanging wall of the thrust, respectively. Same as for the Pleistocene terrace sediments of the middle Moulouya, a recurrent sedimentary pattern, characterized by fining-upward sequences was observed in the studied terrace profiles. Assessing the rates of crustal deformation along this main thrust zone requires age estimations for these Pleistocene terrace deposits of the lower Moulouya on each side of the thrust. Samples for luminescence (OSL/IRSL), electron spin resonance (ESR) and cosmogenic nuclide dating (26Al/10Be, burial dating) were collected in terrace deposits located both in the foot- and hanging walls. Sample preparation and analysis as well as age determination are in progress. The preliminary data mentioned above, soon to be completed by chronological data, agree well with morphometric indicators stating that the whole Moulouya catchment is at disequilibrium state (Barcos et al., 2014). This is confirmed by several knickpoints in its longitudinal profile. Late Cenozoic uplift associated with crustal shortening, which occurred in the lowermost reach of the river, may have both hindered profile rectification of the Moulouya and, at the same time, buffered the effects of long-term base-level changes due to eustatic sea-level variations.

Our study focusses on the ephemeral stream deposits of Wadi Selloum to reconstruct the palaeoenvironmental evolution in direct vicinity of the rock shelter Ifri n’Ammar. As one of the oldest settlement sites of anatomically modern humans (AMH) in North Africa, Ifri n’Ammar documents periodical occupations since ~170 ka. Since these discontinuous settlement dynamics may be related to or influenced by landscape changes and climate forcing, our study aims (i) to identify phases of morphodynamic activity and stability in the deposits of Wadi Selloum by using micromorphological (sixteen thin sections), sedimentological (laser diffractometry, loss on ignition, magnetic susceptibility), geochemical ( XRF and Scheibler method) and mineralogical (X-ray diffractometry) proxies. Furthermore, (ii) a robust chronology for the ephemeral stream deposits is established by applying a combination of optically stimulated luminescence (OSL) and post infrared stimulated luminescence (pIRIR290) dating. Additionally, one collected pottery shard was dated by thermoluminescence (TL) dating for an inter method comparison. The application of luminescence dating techniques to Wadi Selloum deposits yielded burial ages between 1.3 ± 0.2 ka and 102 ± 8 ka covering different phases of morphodynamically stable and active phases. Enhanced aggradation is evident between ~100 and 60 ka, ~21 and 14 ka and during the Holocene. Overbank fines are distinguished by high amounts of allochthonous minerals such as quartz, muscovite, K-feldspar and plagioclase which give rise to higher eolian activity. This leads to the suggestion that morphodynamical activity was dominant during more arid phases. Landscape stability was observed in form of one palaeosol (2B-2C-sequence; OIS 3) and a recent soil (Ap/Ah-Bw-Bk-BC-C-sequence; after LGM), both attributed to the Calcisol group. Pedogenenesis is evident in thin sections by well-developed subangular blocky peds. The main soil forming process is secondary carbonate precipitation in subsoil horizons, supported by pedofeatures such as calcite infillings and hypocoatings. Holocene deposits (6.4 ± 4 to 1.3 ± 0.2 ka) seem to be affected by short-termed changes between landscape stability and hydromorphic activity due to strong variations in its mineralogical and geochemical characteristics. This is supported by a homogeneous and sterile stratigraphy, as well as an insignificant differentiation in soil horizons with only weakly developed pedofeatures. The sediment characteristics present a weak Ap-C-sequence of a calcaric Fluvisol. After ~1.3 ± 0.2 ka fluvial discharge was reduced and incision took place in the Wadi Selloum. Our study provides first insights in the palaeoenvironment around Ifri n’Ammar during the last glacial interglacial cycle and gives first suggestions about climatic conditions during the time of human occupation in Ifri n’Ammar.

The Amik Basin in the Eastern Mediterranean region has been continuously occupied since 6000-7000 BC. The landscape has sustained with highly variable anthropic pressure culminating during the Late Roman Period when the Antioch city reached its golden age. The basin also sustained a high seismic activity (M≥7) as it is a releasing step-over along the Dead Sea Fault. The study focuses on the sedimentary record of the Amik Lake occupying the central part of the Basin. Our objective is to constrain major paleo-environmental changes in the area over the last 4000 years and to unravel possible human impacts on the sedimentation. A diverse array of complementary methods was applied on the 6 m long record. High resolution of mineralogical (XRD) and geochemical (XRF) analyses were performed. Quantitative mineralogical phases of sediments by the Rietveld method were computed using Topaz software. The age of the record is constrained combining radionuclide and radiocarbon dating, and checked using the correlation between the earthquake history and rapidly deposited layer identified. A high sedimentation rate of 0.12 cm/yr was inferred at the coring site. The 4000 years old record shows that significant fluctuations of the lake level and the riverine system inflow into the Amik Lake occurred. The Late Bronze lowstand leaded to punctual dryings of the lake at the end of the Bronze/Iron transition marked by the collapse of the Hittite Empire and during the Dark ages. At that time, the riverine was carrying a large terrigenous input linked to strong soil erosion related to deforestation, exploitation of mineral resources and the beginning of upland cultivation. During the Roman Period and in the later periods, upland soils were partly depleted and the riverine system completely transformed by channelization that leaded to a mashification of the Amik Basin. Chemical and mineralogical composition of sediments is quite diversified reflecting the significant geological variation of drainage basins. Abundant calcareous minerals, especially calcite, aragonite, dolomite and small amount of wollastonite characterize the different sedimentary levels recorded in the lake. Levels relatively rich in fluorite, richerite, enstatite, and wollastonite are a result of the erosion of the ophiolitic rocks from the surrounding Amanos Mountains. These levels are interpreted as corresponding to relatively high erosive periods, while more humid periods lead to more intensive weathering and consequently to the dominance of kaolinite, muscovite/illite and talc more advanced in the relative stability scale, indicating a climate with contrasting seasons. During the most recent Period a marked increase in terrigeneous minerals associated with a rise in dolomite indicates ungoing erosion as well as the drying-out of the lake. [less ▲]

Almost all catchments plot within a small envelope around the Budyko curve. This apparent behaviour suggests that organizing principles may play a role in the evolution of catchments. In this paper we applied the thermodynamic principle of maximum power as the organizing principle. In a top-down approach we derived mathematical formulations of the relation between relative wetness and gradients driving runoff and evaporation for a simple one-box model. We did this in an inverse manner such that when the conductances are optimized with the maximum power principle, the steady state behaviour of the model leads exactly to a point on the asymptotes of the Budyko curve. Subsequently, we added dynamics in forcing and actual evaporations, causing the Budyko curve to deviate from the asymptotes. Despite the simplicity of the model, catchment observations compare reasonably well with the Budyko curves subject to observed dynamics in rainfall and actual evaporation. Thus by constraining the – with the maximum power principle optimized – model with the asymptotes of the Budyko curve we were able to derive more realistic values of the aridity and evaporation index without any parameter calibration.

Contrairement aux empiristes anglais, Wittgenstein récuse l’idée d’après laquelle les actes d’imagination sont définis par leur « contenu », à savoir une « image mentale » qui ne différerait que par son degré d’intensité d’un contenu cognitif (Cf. Hume, Traité de la nature humaine, I, i, 3 ; Wittgenstein, F §621). Parallèlement, Wittgenstein récuse l’hypothèse selon laquelle un « œil mental » ou « œil interne » nous fournirait ces images (cf. e.g. RPP II §66). De fait, les nombreux exemples des Recherches philosophiques comme des textes plus tardifs (cf. e.g. RP §§6, 19 ; F §§98, 571) mettent en scène l’imagination d’un langage, d’une hypothèse, d’un usage, d’un contexte, etc. – autant de choses que l’on ne « voit » pas par l’œil de l’esprit. En adoptant une position assez proche de celles de Reid, Ryle ou Sartre (cf. Glock 1996), Wittgenstein défend alors l’hypothèse d’une imagination sans imaginaire. Ce faisant, Wittgenstein présente l’imagination comme un acte, ou plutôt une « pratique ». Or Wittgenstein dissocie cette pratique de celle de la perception (F §§621-637). Selon le §625 des Fiches, il existe bien un « rapport » entre ces deux jeux de langage, mais pas de « ressemblance ». À titre de premières indications, il semble que les deux pratiques diffèrent pour au moins trois raisons : - Premièrement, Wittgenstein affirme que l’imagination, à la différence de la perception, est assujettie à la volonté (e.g. F §621). Si nous recevons ce que nous percevons, nous pouvons en revanche répudier ou rechercher certaines images. - Qui plus est, en tant que pratique volontaire, l’imagination est soumise aux mêmes règles que celles qui régulent toutes les pratiques. C’est donc une pratique normée : en situation, certaines représentations sont possibles alors que d’autres pas (cf. e.g. RP, §651 : « je ne peux pas imaginer le contraire »). - Il semble enfin que l’imagination, à la différence de la perception, soit une pratique créatrice. Wittgenstein rapproche en effet l’imagination du « voir comme » et non du voir (RP II, 11, RPP §543). Elle joue à ce titre un rôle méthodologique fondamental dans l’économie de la vision synoptique que Wittgenstein appelle de ses vœux. [less ▲]

Drainage of water in soils happens for a large extent through preferential flowpaths, but these subsurface flowpaths are extremely difficult to observe or parameterize in hydrological models. To potentially overcome this problem, thermodynamic optimality principles have been suggested to predict effective parametrization of these (sub-grid) structures, such as the maximum entropy production principle or the equivalent maximum power principle. These principles have been successfully applied to predict heat transfer from the Equator to the Poles, or turbulent heat fluxes between the surface and the atmosphere. In these examples, the effective flux adapts itself to its boundary condition by adapting its effective conductance through the creation of e.g. convection cells. However, flow through porous media, such as soils, can only quickly adapt its effective flow conductance by creation of preferential flowpaths, but it is unknown if this is guided by the aim to create maximum power. Here we show experimentally that this is indeed the case: In the lab, we created a hydrological analogue to the atmospheric model dealing with heat transport between Equator and poles. The experimental setup consists of two freely draining reservoirs 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. From the steady state potential difference and the observed flow through the aquifer, and effective hydraulic conductance can be determined. This observed conductance does correspond to the one maximizing power of the flux through the confined aquifer. Although this experiment is done in an idealized setting, it opens doors for better parameterizing hydrological models. Furthermore, it shows that hydraulic properties of soils are not static, but they change with changing boundary conditions. A potential limitation to the principle is that it only applies to steady state conditions. Therefore the rate of adaptation of hydraulic properties should be faster than the rate of change in boundary conditions. [less ▲]

La culture constitue pour les migrants et leurs pays d’origine un moyen de maintenir des liens réciproques après la migration. Mais quels sont les enjeux de la mobilisation de la culture d’origine pour l’intégration des migrants dans leurs nouveaux pays de résidence ? Cette présentation analyse le déploiement de la culture du pays d’origine à trois niveaux : celui des pratiques quotidiennes des migrants, des politiques d’intégration et de diaspora et enfin, le niveau des associations, en particulier les centres culturels établis en Europe par les pays d’origine des migrants. Les pratiques culturelles des migrants et les actions et institutions culturelles mises en place par les pays d’origine sont confrontées au cadre légal européen en matière de diversité culturelle mais aussi aux politiques et discours sur l’intégration des migrants. La perspective à la fois anthropologique et sociologique adoptée révèle les processus de domination culturelle qui sont à l’œuvre. Elle permet aussi de questionner l’idée d’identité culturelle en montrant le dynamisme qui caractérise les cultures mais aussi la créativité des communautés locales dans un environnement globalisé. Finalement, on constate qu’une variété de facteurs est en jeu dans les processus d’intégration des migrants, que les dynamiques de la culture elle-même déterminent des appartenances multiples et aussi que les identités se développent au sein des interactions entre cultures. Si on ne peut établir de lien causal et univoque entre les pratiques culturelles liées au pays d’origine et l’intégration des migrants dans le pays de résidence, on peut par contre se référer à la notion d’ethnicité et à sa fonction politique (Comaroff et Comaroff, 2009).

The Sam Francis’s colors, literally described as vivid, saturated, pure, vibrant intense and rich, largely contribute to the unique character of his work. This idiosyncrasy explains the interest in conducting an extended study on the Francis’ painting materials through analytical techniques. On the other hand, many Francis’ paintings display colored surfaces that exhibit bronzing, fluorescent or opalescent effects. As a consequence, retouching paint losses from Sam Francis works may become a challenging task for the involved conservators, the degree of the color matching required in the imitative technique being particularly difficult to attain, in the presence of such surfaces. Furthermore, the attained degree of the color match has to be conserved in all conditions of illumination and observation. The use of pigments chemically similar to the original ones is often necessary for matching highly chromatic pigments. Though, many modern synthetic organic pigments (SOPs) possess high color strength. That is why the characterization of the Francis palette would provide helpful information to the conservators, which have to deal with this type of issue. The upcoming Getty publication Sam Francis: The Artist’s Materials, planned for 2016, offered the opportunity for in-depth analyses of hundreds paint samples. Almost three hundreds of paint fragments supplied by the Sam Francis Foundation have been investigated at the GCI laboratory, by using three complementary analytical techniques, Py-GC-MS, Raman and FTIR spectroscopies. The Raman spectroscopy is one of the most efficient techniques for identifying SOPs in paint systems, while the Py-GC-MS and FTIR methods provide essential information concerning the binding media. The analyzed paint fragments were sampled from twenty-nine canvases and works on paper, made between 1946 and 1992. Although, primary established in Southern California, Sam Francis spent numerous long journeys in different places around the world, including Paris, Bern, Mexico City, New York and Tokyo. However, the material study has outlined the uninterrupted use of` certain classes of SOPs in specific colors. For example, copper phthalocyanine (CuPc) pigments were systematically detected in the blue and green samples, while azo pigments have been identified in most of the yellow areas sampled from post 1940s works. Regardless of the support and the paint technique, the Francis’ blues primary contain Ultramarine and/or CuPc blue pigments. And, it has been shown that the bronzing blue surfaces noticed for some of the investigated artworks correspond to PB15-based paint films. The present study has also underlined the recurrent use of perinone orange and dioxazine violet in fluorescent orange and purple area. Despite the early introduction of SOPs, on the Francis’ palette, the works dating from the 1940’s remained mainly composed of traditional inorganic pigments, for instance lead white and red, chrome yellow, viridian and iron oxides. Interestingly, various binding media, i.e. Shellac gum, modified and unmodified oils, PVA, alkyd resins and acrylic copolymers have been identified. Actually, the investigated samples have pointed out the frequent combination of more than three types of binders on a same painting. Through the identification of the various SOPs used by Francis over fifty years, this research provide helpful information for selecting the most appropriate retouching pigments. [less ▲]
