In recent years, inclusive design (a.k.a. universal design or design for all) is one of the developed approaches which aim to consider the diverse human abilities and conditions in the design process. As defined by the European Institute for Design and Disability (EIDD) ‘design for all’ is designing for diversity, social inclusion and equality. Considering the social and demographic changes in the 21st century, which include an international movement towards social inclusion and more specifically the rights of disabled people, an inclusive approach is turning into a necessity for today’s diverse and ageing society. In the case of architectural and urban heritage, the disabled people or in better words those with diverse sensory, mental or mobility abilities who differ from the general public, have the right to experience, interact with, and engage with heritage and its values. As part of an extensive interdisciplinary research on inclusive approaches to built heritage values, which connects the fields of architecture, history, conservation, inclusive design, and digital humanities, this paper investigates the potentials of incorporating digital tools and techniques in the different aspects of this research. The extensive study involves communication between researchers, relevant professional experts, and the historic built environment with the target community of disabled people and in this paper, the digital means to facilitate these interactions have been studied. As a step towards answering the question ‘what are suitable methods and tools for facilitating and acquiring insight into diversely abled people’s engagement with and understanding of architectural heritage and its values?’, it more specifically focuses on the interaction of the disabled people with the historic architecture and urban spaces. Additionally, in a more general approach, by linking the fields of digital humanities and architectural research, the existing tools for the different stages of research ranging from data collection and storage, data analysis, and dissemination are explored. By conducting and elaborating relevant research examples, this study shows how incorporating digital tools and techniques derived from Digital Humanities - such as retrieving data through APIs, textual analysis, creating and querying databases, and data visualization - can facilitate research in the field of architecture and built heritage. Moreover, in studying the relation between disability and the historic built environment, it indicates that acquiring knowledge on the potentials in practical digital tools for disabled people’s interaction with the built heritage, can have a significant impact on the research approach and findings. As for an inclusive approach to built heritage, the disabled people can be taken into account with their prospective extended digital abilities. Hence in today’s digital world, integrating the digital tools and technologies in architectural heritage research is not only a necessary practical mean for conducting research, but can also impact the theoretical approach, allowing to carry out extensive and innovative research in an efficient manner.

This paper proposes a methodology for assessing the risk implied by the potential failure of post-contingency corrective controls. We express such risk in terms of service interruption socio-economic severity to the system end-consumers and argue for considering its magnitude not only in absolute terms, but most importantly in relation to a spectrum of socio-economic metrics fully describing the operation of an electrical power system as per the applicable reliability management approach (presently based on the N-1 criterion). We showcase the proposed methodology by presenting its application through case studies on the single area version of the IEEE-RTS96 benchmark. Our analysis establishes that the proposed assessment scope is quite informative in distinguishing whether the risk implied by the potential failure of post-contingency corrective control is noteworthy or negligible.

This paper explores the entanglement between social status and the bestowal of heroic honours upon deceased political leaders and elite members in the late-classical and early Hellenistic period. Epigraphic and literary sources shedding light on the establishment, justification and social impact of heroic honours practised by different social groups will be discussed, to investigate the implications of the social status of cult agents and recipients upon the definition of the position of honoured humans in relation to the superhuman sphere. This will also imply exploring the types of relationships existing between private heroic foundations and royal divine foundations in the studied period. Contrary to a generally accepted assumption, it will be argued that heroization was common for members of elite families, while it was not the primary option to reward local political leaders, since their honours were principally modelled after godlike honours. For instance, when they came into existence during the mid-Hellenistic period, cults for high-ranking civic leaders were largely modelled on godlike honours for monarchs, but were decreed after death – it will be argued – to preserve a hierarchical distinction between the social status of their recipients. The posthumous bestowal explains why honours for great civic benefactors also drew on typically heroic honours, such as public burial inside the city. However, similar contaminations of heroic and divine honours had already been exploited for the worshipped deceased kings of the early Hellenistic period (e.g. Alexander at Alexandria, Demetrius at Demetrias), so that a certain mixture of divine and heroic features could be said to have been directly transferred from royal to non-royal leaders. In neither case, however, did the presence of heroic features imply that cultic honours for Hellenistic political leaders would be commonly labelled as heroic. A revealing case is that of the Hellenistic leader Aratus, whose “fitting honours” decreed at Sicyon (Polyb. 8.12-7-8; Plut., Arat. 53) are labelled as heroic by moderns only because they were decreed posthumously. Similarly, at Megalopolis, the posthumous honours for the commander Philopoimen comprised a public tomb in the agora – a typically heroic honour – but were labelled as “honours equal to the gods”, not as heroic. We must wait for the late-Hellenistic and Imperial period to trace a significant multiplication of honours for political leaders explicitly labelled heroic. [less ▲]

A travers une sélection de sources littéraires grecques et latines, datant de l’époque d’Alexandre jusqu’à la haute période impériale, on se propose de discuter quelques aspects de la thématique concernant l’existence (ou l’absence) de règles morales auxquelles la conduite des souverains devrait être sujette par rapport à la consommation de la nourriture et du vin. Plutôt que de prendre en considération l’aspect médical de la diète royale, l’étude se focalise sur ses implications sociales et symboliques : notamment, le rôle de la consommation sociale de la nourriture dans la définition d’une royauté qui accepte d’obéir à des règles partagées de modération et d’autocontrôle, promues et protégés par les élites, ou qui, par contre, prétend de manifester sa dimension charismatique à travers une conduite se plaçant consciemment au-delà des limites imposées aux sujets. Les textes analysés discutent le thème du rapport entre le souverain et la nourriture soit à travers les récits de banquets devenus célèbres dans la tradition historiographique et rhétorique, soit par le biais de scènes mythiques ou de banquets historiques imaginaires, où la fiction littéraire sert à thématiser le rapport entre le souverain et les élites ainsi que la mise en place d’une hiérarchie de cour. Un aspect crucial de cette analyse concerne l’identification des classes sociales appelées, dans les textes, à définir les règles du rapport entre le roi et la nourriture, ainsi qu’à exercer le rôle de contrôleurs du respect de ces règles. Un autre aspect à considérer est l’appartenance sociale des auteurs des textes qui prescrivent, approuvent ou stigmatisent certaines pratiques. Considérées ensemble, ces deux perspectives nous permettront de discuter les intérêts et l’agenda des groupes qui s’expriment à travers ces textes. Une attention particulière sera donnée à l’époque de transition entre la fin de la période hellénistique et le début du Principat, lorsque la réflexion sur la sobriété ou la tryphè (ou, selon une perspective critique, la débauche) du roi s’inscrit dans une discussion plus large sur le choix de continuité ou de rupture entre le modèle royal hellénistique et le type de pouvoir monarchique universel expérimenté par les premiers empereurs.

As Aldo Leopold writes, the modern man is a “trophy-hunter”, a “motorized ant who swarms the continents before learning to see his own back yard, who consumes but never creates outdoor satisfactions”, and ultimately “dilutes wilderness and artificializes its trophies in the fond belief that he is rendering a public service” (Leopold, 1949). One of the main issues raised in Leopold’s book A Sand County Almanac is that our perception has been altered by modern technologies such as mechanization, which has deprived the wilderness of its “wildness”, its spatial and ecological meaning. To refocus his/her perception, the viewer must first “learn[ ] to see his own back yard”, understand the ecological complexity of his garden, before hastening to visit remote and over-touristic places. For example, the viewer in national parks tends to consume “sublime landscape[s]” as “series of picturesque scenes” or “object[s] of artistic consumption” and thus devoid of any spatial or ecological meaning (Byerly, 1996). In this presentation, I will analyze representations of the pastoral garden and other natural landscapes in US (non-)fiction—from Henry David Thoreau to Rachel Carson, Edward Abbey, Don DeLillo and Susanne Antonetta—using a redefinition of the “toxic sublime” as a trope. I will also build on this notion (which Jennifer Peeples describes as “the tensions that arise from recognizing the toxicity of a place, object or situation, while simultaneously appreciating its mystery, magnificence and ability to inspire awe” [Peeples, 2011]) to critically interrogate “intrusions” of technological changes in the pastoral landscape and to determine its dangers and causes, whether they are apparent or metaphorical, technological (mechanization, digitalization), toxic ([nuclear] waste, pesticides, and other chemicals), or ideological (pastoral idealization, capitalism, consumerism). Finally, such analysis will allow me to argue that the garden may involve an ecological aesthetics which avoids the trap of “pastoral idealization” (i.e. the representation of the realm of nature as pristine, separate from humans) while creating sustainable senses of self and place.

Ma contribution a pour but de replacer le POxy. 1380 dans le contexte des transferts culturels bien attestés dans l’Egypte gréco-romaine. Je m’intéresserai aux textes égyptiens traduits/adaptés en grec, assez nombreux à Oxyrhynchus : POxy. 465 (noms de divinités égyptiennes avec parfois des explications en grec sur la signification de ces noms), POxy. 470 (allégorisation astrale d’un jeu de société), POxy. 1381 (arétalogie d’Asclepius-Imouthes), POxy. 1826 et POxy. 2466+3319 (le roman de Sesostris/Sesonchosis), POxy. 2332 (un manuscrit de l’Oracle du Potier), POxy. 2552 (un papyrus avec des dessins de dieux égyptiens et de maigres restes d’un texte grec qui pourrait décrire ces divinités [?]), POxy. 3011 (un conte relatif à Amenophthis), POxy. 3285 (traduction d’un manuel légal en démotique). Pour certains de ces textes, le lien avec un original égyptien est difficile à établir. Le seul texte littéraire pour lequel une confrontation entre la version grecque et l’original démotique est possible est la « Légende de Tefnut » connue par un papyrus du British Museum (P. BM 274) du IIIe s. av. J.-C. L’original démotique se trouve sur papyrus de Leiden du IIe s. On ajoutera le « Songe de Nectanebo » (PAnstasy 67), pour lequel les traces d’une traduction sont sûres. A partir de ces textes, je ferai des considérations sur la signification du phénomène de la traduction en Egypte gréco-romaine. Les traductions de textes égyptiens en grec sont attestées pour les textes religieux et les textes juridiques. [less ▲]

Following the theoretical approach developed by Herbold (1995), Gross and Krohn (2005), and Van de Poel et al. (2017), this paper focuses on an on-going social experiment that remains a sensitive challenge for the future of nuclear energy research: the radioactive waste management. More specifically, this paper scrutinizes and compares the attitude of three nuclear waste management organizations (considered here as the experimenter) during the on-going implementation of high-tech waste disposal. Based on 82 semi-directive interviews conducted in Belgium, in France and in Canada, this paper intends to empirically highlight how the experimenter bound to participate in complex networks and unable to completely control the experimental process develops two different attitudes (“open” or “closed” experimental mindset). We sustain that those attitudes produce different public engagements (empowerment or resistance). Particularly, the initiator of the social experiment should adopt an “open” experimental attitude regarding his multiple audiences in order to sustainably deal with uncertainties of decision-making processes related to nuclear energy issues and more globally, energy transition ones.

In most nuclear countries across the world, geological disposal appears as the main option to manage high-level radioactive waste. Many new socio-economic, technical and safety issues arise with the implementation of this option. In the process of addressing these issues, national regulatory bodies stand out as crucial actors. While descriptions of their legal responsibilities abound, studies investigating the future normative choices emerging with the governance of toxic waste are needed. What should be the roles of regulators in dealing with the very sensitive siting process? According to whom? What does it mean for the credibility of the siting process? This presentation aims at systematically comparing three different regulation regimes and infrastructures of high-level radioactive waste management, based on actual perceptions of nuclear stakeholders of how, when and on what should national regulatory bodies intervene. Collected empirical data include a combination of empirical materials—i.e. legal requirements, safety case reports, participatory observations of consultation processes, 82 semi-directive interviews with policy makers, nuclear waste agencies, nuclear regulators in France, Belgium and Canada and local actors such as members of local information and monitoring council (CLIS) and members of the community liaison committee of four volunteer collectivities (CLC).

Understanding how developmental processes change on macroevolutionary timescales to generate body plan diversity is fundamental to the study of vertebrate evolution. In this study we highlight that the application of phylogenetic comparative methods to extinct clades can complement results from living groups, to shed light on the macroevolutionary dynamics of morphology, and its underlying developmental mechanisms, particularly on very long timescales. Sauropterygian marine reptiles (nothosaurs, plesiosaurs, pliosaurs and kin) have long been the focus of qualitative hypotheses about the evolution of body plan, and its relationship with ecological niche occupation. Early taxonomy of the Jurassic-Cretaceous members of this clade classified taxa into two groups corresponding to their gross axial body plan morphologies: ‘plesiosaurs’ characterised by long necks, small skulls and short trunks, and ‘pliosaurs’ characterised by short necks, large skulls and long trunks; these have since been shown not to represent clades. Recently developed phylogenetic comparative methods, applied to trees of fossil taxa, offer an opportunity to quantitatively assess long-standing qualitative hypotheses. Here we use two heterogeneous phylogenetic modelling approaches – AUTEUR and the general FPK model - applied to a comprehensive phylogeny of Sauropterygia. We show that change in relative neck length was primarily enabled by homeotic shifts, with a lesser but important contribution from post-patterning growth, and is best modelled by constant rate Brownian motion. This is in contrast to relative skull size, which is best modelled by a two-peak adaptive landscape. Both of these contradict the traditional hypothesis of long-term divergent trends, beginning in the Middle Triassic. In combination with our other recent work this demonstrates that the apparent Sauropterygian body plan dichotomy resulted from ancestrally high evolutionary plasticity, which was subsequently maintained, and a complex evolutionary history and pattern of ecological diversification.

Environmental factors such as endocrine disrupting chemicals (EDCs) have been proven to produce transgenerational inherited modifications. A rising public health challenge is to determine the effect of complex mixtures of EDCs on the developing body throughout generations. In this study we aim to determine the transgenerational effects of a mixture of EDCs on female sexual development and behavior. Female rats were orally exposed from 2 weeks before gestation until weaning to corn oil or a mixture of 14 anti-androgenic and estrogenic EDCs at low doses. Sexual development (sex ratio, vaginal opening (VO), GnRH interpulse interval and estrous cyclicity) as well as maternal behavior were measured from F0 to F3 generation. In utero exposed females (F1) when raising pups, showed an increased time resting alone and decreased time licking and grooming pups. F2 (animals whose germlines were exposed) and F3 exposed animals showed an altered sex ratio in favor of males and F2 and F3 females showed delayed VO. F2 and F3 females followed for estrous cyclicity showed significant alterations of estrous cyclicity characterized by a significant increase in the time spent in estrus and decreased time spent in diestrus. F3 females presented an increased GnRH interpulse interval compared to control. Overall, data shows that gestational exposure to an EDCs mixture can affect maternal behavior and sexual development during several generations. The effects observed in the F3 generation suggest the presence of transgenerational epigenetic mechanisms. [less ▲]

The genus Psiadia Jacq. Ex. Willd. belongs to the Asteraceae family and includes more than 60 species, which are well represented in Madagascar and the Mascarene islands (La Réunion, Mauritius and Rodrigues). Several Psiadia species are used traditionally to treat various ailments such as expectorant for treatment of bronchitis and asthma, colds and abdominal pains. According to litterature, only a few species have been studied for their chemical composition. In order to make a comprehensive study of the genus Psiadia in the Mascarene islands, a chemotaxonomic study was conducted on 11 species endemic to La Réunion. The aim was to identify chemical markers by a metabolomic approach using GC-MS and GC-FID for volatiles compounds and 1H NMR for non-volatiles compounds. The 11 studied species were collected from different locations and seasons in order to analyze the geographical or seasonal variability of the chemical profile of each species. This study led to two different classifications of the 11 species in terms of composition of volatiles and non-volatiles compounds. [less ▲]

Social scientists and migration scholars have a growing interest in how and why migrants engage in transnational political movements in both their home and host countries. Migrants are active agents participating in transnational social movements. They create, transform, and exploit transnational networks to engage in political movements in their homeland and in their hostland from cities. This chapter aims to answer the following questions: how do global cities shape transnational fields of social mobilization? What is the nexus between these transnational fields of social mobilization and access to welfare states? Theoretically, this contribution introduces a new spatial level of analysis to unpack the dynamics and dimensions of migrant social movements organized in global cities that connect Latin Americans to their countries of origin as well. By focusing specifically on the city of Brussels, this contribution analyzes the impact of global cities in shaping the capacity and desire of Latin American migrants in engaging in political movements. Empirically, this chapter presents two case studies where Latin Americans living in Brussels engage in political transnational activities to change their living conditions both in their host and home cities. These examples illustrate the role of migrants influencing and shaping welfare state and political systems that traverse the Atlantic Ocean between their sending and receiving societies. [less ▲]

The Roman upper-class houses are well-know thanks to Vitruvius' De Architectura and Pompeii's excavations. This atrium house form, as encountered in the Vesuvian cities, is typical of the late Republic and early Empire. At the same time, however, a new form of residential building - the insulae - progressively took the place of this kind of domus in Rome and Ostia. However, some of them were maintained over many centuries, as suggest the three atrium houses along the Vicus Patricius represented on a fragment of the severian Forma Urbis Romae (n°543). Ostia is a good case study to investigate the maintenance of this architectural form in the Empire (sens temporel). Indeed, the urban growth of Ostia is continuous from the fourth century BC to the late Antiquity. Most of the houses built in late Republic and Early Empire are knocked down during this time, like the republican Casette Repubblicane (I, IX, 1) or the Augustean Domus con Portico di Tufo (IV, VI, 1) because the insulae became the common type of dwelling at the mouth of the Tiber during the second century AD. These destructions reflect many transformations in social practices of the Roman aristocracy in the harbour of Rome. Nevertheless, some households prefered to preserve their domus rather than construct new more profitable ones, as suggest the Domus di Giove Fulminatore (IV, IV, 3), the Domus della Nicchia a Mosaico (IV, IV, 2) or the Domus a Peristilio (IV, V, 15-16). These ancient domus contrasted with the new insulae and they indicated the social rank of their owner in the new townscape. This paper will discuss the case of these Augustean houses in the imperial urban fabric of Ostia, with a focus on the Domus a Peristilio, owned by the familly of C. Fabius Agrippinus, consul suffect in 148 AD. Indeed, the excavations undertaken between 2002 and 2010 within the so-called Schola del Traiano (IV, V, 15-16) offer some stratigraphic evidence - unpublished - from the building yard to the demolition of this aristocratic house. These archeological investigations have made it possible to envisage many repairs and transformations that took place over time. This building maintenance betrays the homeowner's will to adapt his dwelling to technical progress, like water supplies, or the decorative program to the decorative fashion. All in all, this talk about the upkeep of atrium upper-class houses during the Empire re-evaluates the features of the society in Roman Ostia. [less ▲]

Among the many experiments in democracy, nuclear waste management is a fascinating case to question the co-production of publics and experts knowledge. Nuclear waste management (NWM) organizations know that audiences are not trusting worshipers anymore, but rather critical spectators, so they adapt their knowledge production strategies accordingly. Several authors already underlined that reception and production sides of knowledge occur at the same time in particular physical and social spaces, which all have their own procedural and normative rules of what should and will be considered as reliable. One key argument is that there is no knowledge performer (and performance) without an audience and vice versa. Publics and NWM organizations could metaphorically be considered as partners dancing together on a particular stage. In this sense, dancing partners jointly participate in the performance as they can each produce and receive knowledge, to which they can be “subjected” or of which they can be an “agent” (Jasanoff 2011, Hilgartner 2000, Ezrahi 1990). But do publics and experts equally perform the dance in nuclear waste experiments? Is one partner more authoritative than the other? Do publics have to wait for the invitation or can they sometimes lead the dance? Is one dancer “hitting the notes, but missing the music” (Wynne 2006)? And whose music? [less ▲]

Since its inception, the European Union (EU) has pushed its borders by pursuing a European unification process. Within this framework, Article 49 of the Treaty on the European Union enshrines that any State which is “European” can be eligible for membership of the EU. In other words, the State must belong to “Europe”, a fundamental condition that indirectly but legally sets a limit to EU expansion. Nonetheless, the concepts of “Europe” and “Europeanness” have never been officially defined by the EU institutions, which casts doubt on the maximum external borders that the EU could take on. Failing an official definition, the EU institutions have still provided both implicit and explicit interpretations of the term “European” in their institutional discourse, especially in the course of enlargements and treaty-making processes. Building on a content analysis of primary sources mainly kept in the Historical Archives of the EU at the European University Institute in Florence, the article investigates these interpretations and how they resulted in both the bordering and the ordering of Europe through normative conditions and politico-cultural constructs, as well as shaped an institutional conceptualization of “Europe(-anness)”.

This communication suggests that Belgian forensic mental health policy is created every time individuals gather to talk about it.  It argues that looking closely at micro-level interactions is essential to understanding how policy takes shape.  Based on ethnographic descriptions of strategic committee meetings, this article first shows that the meeting frame involves a succession of formal and informal kinds of talk, including pre-meeting and coffee break discussions.  Second, and consequently, the meeting enables new connections between previously separated events taking place in multiple arenas.  Third, documents supporting the meeting mediate the various relationships (i) between participants, by providing them with a common reference, and (ii) between the meeting frame and its environment, by invoking parts of this environment in the meeting room and conversely.  In this way, talk in meeting gives meaning to the policy by affording the development of new socio-material relationships.  'Talking policy' is, in turn, the very way in which policy makers and experts reveal and interpret its content.

Je propose de discuter de la désituation : un néologisme discrètement utilisé par Sartre qui apparait dans les Questions de méthode et qui est utilisé dans le Flaubert. Sartre y suggère que se désituer consiste à « détruire ou cacher le rapport de réciprocité » (T. III, 1972, p. 12). Après une discussion définitoire, j’inscrirai le concept dans la généalogie sartrienne de la notion de situation (à travers l’utilisation qu’en fait Sartre dans l’Esquisse principalement). Ce détour me permettra de relier la désituation à la problématique émotionnelle et, dès lors, d’interroger le trouble schizophrénique à la lumière de cette proposition. Celle-ci sera mise en tension avec les propositions contemporaines de la psychopathologie phénoménologique qui identifient des anomalies de l’expérience du soi et du rapport au monde en tant que caractéristiques centrales de l’éprouvé schizophrénique. J’insisterai particulièrement sur la notion d’atmosphère et, in fine, proposerai une compréhension de l’existence schizophrénique comme un vécu de désituation. [less ▲]

The contemporary Belgian health policies (mental health, chronic diseases, rare disease...) constitute a real challenge in terms of governance, in the sense that they mobilise interdisciplinary networks of actors. Indeed, Belgian health policy plans in different health sub-sectors request cross-sectoral or cross-organisational collaborations (Clavier & Gagnon, 2013; Crosby & Bryson, 2010) as an answer to complex societal problems (Daviter, 2017). In this context, coordinators emerge as intermediary actors entrusted with a political mandate consisting in connecting different levels of action, sectors and organisations. With this communication we aim to study the coordinators’ place in the forensic mental health governance structure. Three different methods of data collection have been combined. It includes document analysis (i.e. policy plans, coordinators job descriptions), more than sixty semi-structured interviews with key stakeholders (policy-makers, coordinators and network professionals) and fifteen observations of meetings (federal coordination meeting with political authorities and local network meetings organised by coordinators). We argue that this triangulation of data collection methods allowed us to comprehensively understand the coordinators’ place in the governance structure as well as their role in the policy processes. The collected data were analysed in Nvivo thanks to a system of coding both developed inductively as well as deducted from the literature review. This abductive methodology helped us to constantly confront the field reality with the scientific literature. Thanks to our methodology, we could follow the implementation and construction processes of the forensic mental health policy plan since 2016, both at the federal (top-down practices) and local levels (bottom-up practices). Our empirical material has showed that coordinators are key actors of the forensic mental health sector governance structure. By being at the intersection of several sectors, institutions and persons, coordinators indirectly enhance communication between previously separated actors (i.e. from justice, health and welfare sectors). First, coordinators constitute a bridge between the justice and health sectors and, therefore, allow the articulation of those different stakeholders at different levels of action (i.e. between justice and health organisations). The arrival of those professionals has strongly reinforced the cross-sectoral governance of the sector. Second, by being situated in between the federal and local levels, coordinators also ensure the vertical integration of policymakers’ and professionals’ visions, by reinforcing both top-down and bottom-up practices. This contribute to strengthening the vertical line of governance. Finally, coordinators also enhance the horizontal integration of the different network partners’ ideas, information and concerns between one network’s partners, reinforcing the network governance. Contemporary health policies ask for new modes of governance, promoting collaborative governance (Kislov et al., 2017) and setting up networks to enhance collaborations (Buttard, 2008). More specifically, mandated networks show a special need for mixed governance styles in order to achieve a higher level of coordination when facing a mandated network (Rodriguez et al., 2007). As we saw with the forensic mental health sector, coordinators allow to overcome certain barriers in terms of governance and enhance at the same time different styles of governance (i.e. vertical and horizontal). Thanks to their intermediate position coordinators support the development of an effective collaborative governance including a diversity of stakeholders. However, the research showed that the coordinators’ style of leadership (transformational, integrative, and authoritative) substantially defines the policy governance structure. Therefore, we would like to raise the question of the training and selection of those emergent intermediary professionals. [less ▲]

Die Adorno-Forschung findet derzeit wachsendes Interesse im französischsprachigen Raum. Zwar wurde Adornos Denken in Frankreich spät und immer stückweise rezipiert, wobei vor allem seine Arbeiten zur Soziologie, Ästhetik und Philosophie herauszuheben sind, aber es wäre doch verfehlt zu glauben, dass es zu seinen Lebzeiten völlig übergangen worden wäre. Seine Beziehungen zu verschiedenen französischen Zeitschriften wie Diogène, Mercure de France, Preuves, Communications und Arguments sowie zu Gelehrten wie Edgar Morin, Kostas Axelos, Lucien Goldmann und anderen bezeugen, dass er in der Tat bestimmte Tendenzen des französischen Denkens bereits seit den 1950er Jahren stimuliert hat. Überdies legen seine Auftritte in der Sorbonne 1958 und im Collège de France 1961 Zeugnis ab von seiner Auseinandersetzung mit den intellektuellen Kreisen Frankreichs und insbesondere mit der Bedeutung der Heidegger’schen Philosophie für sie, mit einem Denken also, das sich ja als so entscheidend für die geistige Entwicklung des Frankfurter Philosophen und für die Erarbeitung der Negativen Dialektik erwiesen hat. Der Austausch und Dialog, der sich zwischen Adorno und Frankreich entfaltete, ist freilich keineswegs auf eine einfache Rezeption beziehungsweise eine Aktualisierung seiner kritischen Theorie beschränkt. Die Praktiken, die in Frankreich in der mehr oder weniger konfliktgeladenen Kontinuität seiner Pariser Auftritte entstanden, entwickelten sich sehr rasch in ganz spezifische Richtungen – man denke nur an die Fragment-Praxis in Arguments oder an die semio-anthropologische Faszination gegenüber der Kulturindustrie und der Massenkommunikation, wie sie sich um Intellektuelle wie Morin, Barthes und Friedmann in der Zeitschrift Communications herausbildete. Zwischen der Radikalisierung der Kritik an der Kulturindustrie in der Nachfolge der Adorno’schen Kritik und einer reformistischen Reaktion auf dieselbe, zeigen die Entwicklungen im französischen Denken eine ganze Reihe von Verwerfungen, die es ermöglichen, die Bedeutung des Dialogs mit der Frankfurter Philosophie und einer gewissen Taubheit ihr gegenüber richtig einzuschätzen. Im Gegenzug bildet die Beziehung, die sich allmählich zwischen dem deutschen Philosophen und Paris geknüpft hat – einer Stadt übrigens, die er als unbedeutend im derzeitigen industriellen und rationellen Entwicklungsprozess der modernen Gesellschaft ansah – , ein Schlüsselelement seines Denkens und Werkes und stellt gewissermaßen einen Raum bereit, der kritischen Abstand und philosophische Reflexion fördert. Praktisch jede seiner Auslandsreisen führt über Paris, wo er in der Tat eine Form intellektuell heiterer Gelassenheit und geistiger Obhut für das „staatenlose“ Denken zu seinen Minima Moralia vorfindet. Adornos Pariser Aufenthalte schreiben sich in sehr verschiedenartige sozio-politische Kontexte ein und müssen in ihrer je eigenen Besonderheit gesehen werden, und zwar als Verbindungen eines selbst in Bewegung befindlichen Denkens zu einer jeweils anders sich darbietenden historischen und geografischen Situation. Wie also soll die Chronologie des Adorno’schen Werkes im Lichte der verschiedenen Pariser Aufenthalte und unter Berücksichtigung der jeweiligen Pariser Gesprächspartner, die seine theoretischen Ansichten und Interessen geprägt haben, neu überdacht werden? Inwieweit beeinflussten bestimmte Kontakte – wie etwa zu Jean Wahl und Georges Bataille 1937, zu Michel Leiris und René Leibowitz 1951 oder auch zu Samuel Beckett 1958 – möglicherweise sein Denken oder bezeugen im Gegenteil die Alterität beziehungsweise Isolation der französischen Kunstszene im Verhältnis zur deutschen Philosophie? So befragt, könnten vielleicht die Pariser Aufenthalte die bisweilen widersprüchlichen Verwerfungen, Umschwünge, Unsicherheiten und die intellektuellen Interessen Adornos neu beleuchten. Paris bleibt für ihn außerordentlich wichtig, weil ja dort die zwiespältigste und auch originellste Rezeption der deutschen Philosophie stattfand, von Hegel bis Heidegger über Marx, Schopenhauer und Nietzsche, also all der Denker, mit denen die Frankfurter kritische Theorie in Diskussion und Widerspruch steht. Die Vorträge im Collège de France stellen eine echte Phase der Vorbereitung, des Ausprobierens und des Gegeneinanderhaltens der Grundideen der Negativen Dialektik dar, zumal ja die drei in französischer Sprache gehaltenen Vorträge die jeweilige Basis mehrerer Teile dieses Adorno’schen Hauptwerks bilden. All diese verschiedenen Aspekte des Verhältnisses zwischen Adorno und Frankreich wollen wir vertiefen und dabei seine Rezeption zu Lebzeiten genauer erforschen, das heißt seine Pariser Auftritte und seine beruflichen und persönlichen Beziehungen zu den französischen Intellektuellen in den 1950er und 1960er Jahren; aber darüberhinaus soll auch seine posthume Rezeption untersucht werden. Wir schlagen folglich vor, im Rahmen dieser Studientage die Reflexion in zwei Hauptrichtungen zu lenken: - Eine erste Fragestellung richtet sich auf die Art und Weise, wie die französische Intellektuellenszene sich im Verhältnis beziehungsweise in Reaktion oder gar Gleichgültigkeit gegenüber der sich intensivierenden Rezeption Adornos in Frankreich entwickelt, und zwar von der Masseninformation und kommunikation über die Praktiken des Nouveau Roman bis hin zur strukturalen Semiologie. Inwieweit sind seine Auftritte, die Übersetzungen seiner Schriften und die Kommentare zu seinem Werk Antrieb beziehungsweise Hemmschuh der jeweiligen intellektuellen Strömungen in Frankreich gewesen? - Im direkten Anschluss an diese Fragestellung sollten die französischen Auftritte Adornos unseres Erachtens zugleich als in sich abgeschlossene Denkprozesse und als Neuanstöße zu einem dynamischen dialektischen Denken reflektiert werden. Daher gilt es, seine und die von ihm beeinflussten intellektuellen Arbeiten unter zweierlei Gesichtspunkten zu untersuchen: einerseits durch die Erforschung der Abhandlungen in ihrer je eigenen kontextuellen, philosophischen, raum-zeitlichen Singularität und andererseits durch ihre jeweilige Verortung im weiteren Raum der philosophischen Entwicklung, wobei sämtliche konkrete Praktiken des Diskurses, des Verhältnisses zum publizierten Werk, des formlosen Austauschs und der öffentlichen Rede mit einbezogen werden sollten, um zum Verständnis für die Bedeutung der deutsch-französischen Dialoge für Adornos Werk zu gelangen.

Lameness in dairy cows is an issue that can vary greatly in severity, and is of concern for both producers and consumers. Metabolic disorders are a major problem in themselves, and, next to this, can cause lameness. Indeed, lameness is an often occurring consequence of various metabolic disorders, such as sub acute ruminal acidosis (SARA), ketosis or milk fever. The caused lameness event can occur weeks to months after the metabolic disorder making the detection of causality difficult. Moreover, detection of many metabolic disorders is very challenging and not straightforward. Mid-infrared (MIR) technology is already used for the prediction of major milk components, such as fat or protein, during routine milk recording and for milk payment. It was recently shown that this technology can also be used to predict novel components, linked to metabolic disorders of cows, such as ketone bodies, citrate and minerals. In the context of limiting the occurrence and severity of lameness, early prediction of lameness could help indicate the need to adapt the management and the environment of a cow at risk of lameness. Therefore, the aim of this study was to analyze the temporal link between metabolic disorders and lameness events, using locomotion scores of the cow and MIR based milk biomarkers for different metabolic disorders of her milk from previous test days. Data recorded between, July 2014 and December 2014, consisted of 9324 records, from 3895 cows and 122 farms. Correct definition of the response variable is an important aspect as extremes in lameness severity, expressed on lameness scales, were more easily predictable. First results were obtained using covariance functions on correlations computed between averaged metabolites and lameness scores, per animal, across the lactation stage classes. Correlations tended to be higher when comparing predicted metabolites with lameness in the three following months, rather than the same one, hinting at a temporal relationship. [less ▲]

The Belgian internment measure has been oscillating between justice and health since its first formulations. The 2016 Internment policy plan and the legal framework support a strong collaboration between those two fields. As Rutherford (2010) stated: “these last two decades there has been a convergence between mental health and criminal justice policy, legislation, systems and practice, [...] boundaries between the two systems are becoming increasingly blurred.” This communication aims at illustrating how the emergence of new hybrid professional roles and the evolution of professionals’ practices come to foster the blurring of mental health and justice sectors’ respective boundaries.

Tutorial: Patients with disorders of consciousness are by definition unable to communicate. This makes the evaluation of their state of consciousness a major challenge. To date, there are not standardized guidelines as to how a post-comatose patient can be evaluated by means of assisting technologies. With this tutorial, we bring together specialists from three expert centers dealing with intensive evaluation of the state of consciousness in patients sustaining severe brain injuries. Our aim is to illustrate how we can infer a clinical diagnosis by integrating different data from behavioral and brain function as measured with different technological modalities. Specifically, we will discuss the case of a patient for whom behavioral, electrophysiological and neuroimaging data have been acquired with the aim to provide a global diagnosis of the state of consciousness. We will show how each of these evaluations are performed in step-by-step manner. Each presenter will further illustrate the methodological challenges and pragmatic solutions towards the inference of valid conclusions. In order to integrate the results into a global diagnostic category, we wish to engage the audience to participate interactively towards the composition of a final diagnostic report, as we typically do at our clinical sites [less ▲]

Research on customer participation in service recovery is surging, yet empirical examinations provide mixed results. This paper reports the results of a meta-analysis of relationships linking customer participation in service recovery to customer outcomes, offering two main contributions to the literature. First, even though these relationships are positive and significant, the overall effect of customer participation in service recovery on customer outcomes is rather weak. Second, the mixed findings reported in literature can be attributed to differences in the service failure controllability (i.e. failures with unclear causes), cultural background of the respondents (Eastern versus Western), setting (offline versus online), method (survey versus experiment), and the journal quality (elite versus non-elite journals). We conclude with several avenues for further research. [less ▲]

The imperial streets of Ostia and Rome - as they appear on the severian Forma Urbis Romae - were edged by many shops, which shaped the streetscape of these cities. This situation is common in modern downtown, but it was not in Antiquity. In greek cities such as Priene or Olynthus, the space of the street is so different : since there is few doorways in the buildings façades, the frontages are more simple and the buildings more segregated from the thoroughfares. We observe the same characteristics in some italian cities, like Norba, destroyed at the begining of the 1st century BC. Indeed, the streetscape seems to change from the Late-Republic in Italy : at Ostia for instance, we observe late-republican tabernae along the Decumanus, under the Horrea of Hortensius. The progressive development of shops along urban thoroughfares shows evidence of the economic facilities offered by the space of the street, made up of building façades, roadway and street furnitures. This built framework hosts shopkeepers and their commercial activities, because it gave some market opportunities to them, just as a macellum, but far and wide throughout the city. So far, this architectural environment has been neglected in favor of the street network and the traffic. This paper would consider the evolution of the architecture of the streets in Italy, between the Mid-Republican time and the Severian period, and highlight the role played by the "street-as-market" in the organisation of urban economy.

L'identité européenne est indéniablement au cœur de l'intégration européenne. En effet, l'article 49 du Traité sur l'Union européenne stipule que tout Etat qui souhaite devenir membre de l'Union européenne doit être " européen ". En d'autres termes, l'identité européenne, ou l'européanité, d'un Etat et son appartenance à l'Europe conditionnent, en tout premier lieu, son éligibilité à l'Union européenne. Toutefois, les notions d'Europe et d'européanité n'ont jamais fait l'objet d'une définition explicite, consensuelle ou officielle, ce qui peut donner lieu à diverses interprétations. A défaut d'une telle définition, les institutions de l'Union européenne ont été amenées à fournir leurs propres interprétations et définitions, aussi bien explicites qu'implicites, du qualificatif " européen " au fur et à mesure du processus d'élargissement et des demandes d'adhésion. Sur la base d'une analyse de contenu de sources primaires principalement conservées aux Archives historiques de l'Union européenne à Florence, cet article explore les interprétations institutionnelles des notions d'Europe et d'européanité depuis les prémices de l'intégration européenne, ainsi que leur participation à la définition de ces notions et, in fine, à la construction de l'identité européenne des Etats à travers la mise en place de conditions d'éligibilité normatives.

The paper explores the interaction between different kinds of social agents in the funding and management of cult foundations for the dead in the late-classical and Hellenistic period. Textual and archaeological dossiers will be discussed in order to 1) investigate the occupation of sacred space in existing sanctuaries and other public spaces as well as the creation of new sacred places, specifically meant to host ritual practice for dead individuals or groups; 2) provide a comparative analysis of the patterns of establishment, funding and management of cult foundations pertaining to civic, royal, individual or groups' initiatives; 3) explore the forms of interaction between various agents involved, e.g. between civic and private initiative in funding and management. When possible, these considerations will also be integrated with an evaluation of the religious status attributed to the honoured persons, with particular attention to the semantic fields of heroization and deification. Thus an attempt will be made at tracking down possible general trends of religious administration beyond local particularities, and at schematizing these configurations in a model taking into account four factors: the social status of ritual agents and recipients; the religious status acknowledged to cult recipients; the methods of funding and management; the degree of monumentalization and social impact of the cult foundations.

Structural fire engineering has long relied on a prescriptive approach based on isolated member behavior under continuously heating standard fire. By definition, this approach does not allow comprehending the effects of interaction between members of a complete structure nor the effects of real fire exposure. Yet, such effects can have a significant influence on the response of real buildings to fire. Notably, when a structure has survived a fully developed fire, the cooling phase that inevitably follows generates effects that may endanger the structure stability. This has been attested by real structural collapses and poses a specific threat to firefighters. However, the behavior of structures under natural fire and the causes of failure during cooling are still not well understood. This research investigates the response of steel-framed structures to natural fires with the aim to analyze the possible collapse mechanisms during cooling. Numerical simulations by nonlinear finite element method are conducted for different fire scenarios and structural designs. The simulations model the thermo-mechanical behavior of the frames accounting for the interaction between members during the entire fire duration until burnout. Different collapse mechanisms during cooling are highlighted and discussed, including connection failure and progressive collapse under localized fire. In the latter case, collapse of members not directly affected by the fire occurs during the cooling phase. These mechanisms result from a complex combination of several factors, such as the recovery of thermal elongation, the recovery of stiffness, and the prior development of permanent strains in the heated members. The results show that steel-framed structures are subject to collapse during the cooling phase of natural fires. Therefore, natural fires with heating-cooling sequences represent a loading case that should be considered in structural fire analyses and could lead to specific design provisions to prevent the occurrence of collapse during cooling.

Use-wear analysis of stone tools is a powerful means for understanding lithic assemblages and past human behaviour. While the method has traditionally only played a supportive role in lithic studies that have been predominantly oriented towards understanding the production sequences of stone tools, recent years have witnessed a change in the way functional analysis is applied. We present here the reasoning behind the project Evolution of stone tool hafting in the Palaeolithic, aimed at understanding long-term and large-scale changes in hunter-gatherer technology, and how this affects the way the method is applied. New results from three Gravettian sites will be used to illustrate the potential of the method in understanding the formation of lithic assemblages and the human choices behind it. This study is the first large-scale application of the hafting wear method to Upper Palaeolithic assemblages, and has so far involved the detailed analysis of c. 1050 stone tools, most of which Gravettian, from the cave site Hohle Fels, the open-air site Maisières-Canal and the rock shelter Abri Pataud. Selected functional data will be presented with a special focus on the often overlooked domestic tools. The purpose of the presentation is to give perspectives on the variability of Gravettian assemblages by discussing tool design and function, lithic recycling, and chronological and site-specific patterns in tool hafting. In addition to proposing new interpretations, the goal is also to point out open questions and to encourage interaction and collaboration between technologists and functional analysts. [less ▲]

In his founding work published at the end of the 1970s, Marcel Otte defined three typological facies within the Gravettian in Belgium (Otte, 1979). However, because chronological data were extremely limited at the time, the question of the potential temporal value of these facies was left open. It was not until the round table in Les Eyzies-de-Tayac in 2004 that the accumulation of stratigraphic observations and radiocarbon dates allowed defining their chronological order and proposing a reconstruction of the Belgian Gravettian sequence (Otte and Noiret, 2007). The three typological facies were then tied together in an evolutionary model based on several particular tool types that appeared within the earliest facies and persisted all the way until the most recent facies. However, this persistence of fossiles directeurs is only visible at cave sites, which are the most Gravettian sites in Belgium. Building on the recently collected data on the open-air settlements of Maisières-Canal and Station de l’Hermitage, as well as on the caves and the Upper Shelter of Goyet, we propose to revise the classical seriation of the Belgian Gravettian. We can distinguish two main phases with more or less well-defined limits: a well-documented early phase that includes two distinct and clearly defined technological traditions is followed by a “recent” phase that is characterized by several typological markers but remains otherwise poorly known. In fact, no reference site is available at present for the “recent” Gravettian in Belgium. Instead, this phase is represented only at cave sites where the artefacts that can attributed to it are very often mixed with other chrono-cultural markers, including those belonging to the traditions of the early phase of the Gravettian.

Speleothem cave deposits (particularly stalagmites) represent often high–resolution continental records for reconstruction of paleoclimate and/or paleoenvironmental conditions through their trace elements concentrations (e.g., Mg, Sr and Ba) and stable isotopes compositions 18O and 13C (Fairchild, et al., 2000, 2001; McDermott, 2004). The advantage of using very young speleothems (1-120 yrs timescale) is the possibility to validate such reconstructions when compared with historical and instrumental records (e.g., meteorological parameters). U-series radiochronology remains the most suitable method to obtain reliable absolute ages of speleothems even for relatively young deposits, avoiding uncertainties related to multiple sources of CO2. In cases of pristine and clean speleothems with relatively high U-contents, precise U/Th ages can be obtained even for very recent stalagmite (e.g., Shen et al, 2013). However, this is rarely the case because speleothems often contain low U-contents (ppb levels) and traces of detrital contaminants, which require often complicated age corrections. Such corrections result in relatively high uncertainties on the final age calculation. We present here the results of 210Pb measurements carried out on high growth rate and laminated stalagmite from Han-sur Lesse cave, southern Belgium. The 210Pb results show a clear well defined exponential with depth decreasing allowing to calculate an age-depth model. These 210Pb ages were confronted to ages of the stalagmite obtained by counting laminae and considered as true ages. The results show a good agreement between the two ages within the analytical errors and open a new potential for dating recent not laminated speleothems using 210Pb excess method. [less ▲]

Following the discovery of Gravettian stone tools and faunal remains in a field near the village of Ormesson, the open-air multi-stratified site of Les Bossats has been excavated since 2009. Beyond extending the already long list of Gravettian sites in the Loing Valley, its discovery is exceptional thanks to the preservation of the occupation layer within a loess deposit and the diversity of the remains that is remarkable for an open-air site. Dated to the beginning of Heinrich event 3, the Gravettian occupation of Les Bossats has yielded a high number of lithic artefacts, totalling approximately 16.000 at the moment. The lithic technical system uses primarily the local Campanian flint, but also Tertiary flint from further away was brought to the site in the form of blanks and small cores. Straight regular blades were produced on elongated cores with a soft stone hammer through a bidirectional and symmetric reduction sequence. Several strategies were used for producing bladelets. Some of them were integrated in blade production, while others were independent of it. Burins and backed pieces are clearly overrepresented in the assemblage, whereas other types of retouched tools are rare. Microgravette points dominate among the backed pieces. Preliminary observations of impact damage confirm that at least some of these elements likely served as armatures for hunting, thus supporting the hypothesis of an occupation that was mostly dedicated to this activity. After nearly 10 years of excavation, the Gravettian occupation of Les Bossats has become a new reference site for the early phase of the Gravettian. The integration of varied data from other sites across the Paris Basin allows evaluating the potential of this region for future palaeoethnological and palaeohistorical research on the Gravettian, following the famous example of the Final Magdalenian from the same region.

Traveling Ionospheric Disturbances (TIDs) are of the utmost importance in energy and momentum transfer from the lower atmosphere to the ionosphere. The upcoming NASA’s ICON mission will address these topics by performing remote sensing of ion and electron density, velocity and temperature from the bottom of the ionosphere up to the altitude of the spacecraft. More precisely, the ICON Far UltraViolet (FUV) instrument will image the ionospheric limb in two wavelength channels: the first one is dedicated to atomic oxygen and detects its emission at 135.6 nm. The second one studies the N2 Lyman-Birge-Hopfield (LBH) band around 155 nm. With an inclination of 27° and a circular orbit at an altitude of 550 km, the ICON mission will focus on low-latitudes only. Using ICON/FUV data, TID detection can be performed following two different approaches. The first possibility makes use of raw measurements (level-1) of the limb, corresponding to the line-of-sight integrated values of the O+ ion density. The second option consists in analyzing vertical profiles of the O+ density (level-2 product) derived from the inverse Abel transform of level-1 data. In this study, we simulate integrated O+ emission based on a background ionosphere provided by IRI-2016 on which we superimpose a TID of known characteristics: wavelength, period and velocity. This work investigates the retrieval of TID characteristics with algorithms using either level-1 or level-2 data. Given that the assumed spherical symmetry used in inverse Abel transform is rarely met in low-latitude regions, TID detection using ICON/FUV could prove to be more reliable using line-of-sight integrated values directly provided by the imager rather than using the inverted O+ profiles. We investigate the advantages and drawbacks of both above-mentioned methods in detecting TIDs and untangle possible ambiguities that may arise from the spherical symmetry hypothesis. [less ▲]

Electrical resistivity tomography (ERT) is increasingly used in the context of agriculture since the measured resistivity distribution can be linked to soil moisture, soil structure or pore water salinity. Due to its minimally invasive character, its spatial coverage and its monitoring abilities, ERT can be used to study field heterogeneity and competition between plants, quantify water fluxes throughout a growing season or distinguish preferential flow pathways in soils. Nevertheless, a lot of challenges still remain. From a mathematical point of view, the inverse problem linked to ERT is ill-posed. To solve it, the inverse problem is often regularized with a Tikhonov-type approach resulting in a smoothed resistivity distribution. However, in reality strong contrasts can exist due to e.g. compacted soil layers due to ploughing, water infiltration fronts, etc. and in that case other operators have been proposed to regularize the inversion. Taking into account spatial heterogeneity of petrophysical characteristics and providing a realistic uncertainty estimation are additional challenges, which can be addressed using stochastic approaches. Monitoring data provides further elements to constrain the inverse problem: data can be replaced by data difference and regularization may incorporate the temporal dimension for instance. However, such constraints require their compatibility with the studied temporal process, which is not always straightforward. Several alternative strategies are being developed, such as coupled hydrogeophysical inversion, or stochastic approaches using a prior falsification/validation method following a Popper-Bayes philosophy. In this presentation, we will illustrate the mentioned challenges and some recent developments in the context of agrogeophysics. [less ▲]

Irrigation, particularly pivot-center, is widely used around the world to fill the need of crop watering. This method of irrigation has a low efficiency compared to other methods of irrigation such as drip systems and generally they use water without consider the real need of plants. In this paper we propose an automation system based on the Internet of Things (IoT), Geographic Information System (GIS) and quasi real-time in the cloud of water requirements to improve the efficiency of water use. Indeed, each segment of the pivot-center moves at a different speed compared to others; thus, must be individually controlled to optimize the yield of irrigation. Moreover, it necessary to integrate factors such as stage of crops’ development, heterogeneity of soil, runoff, drainage, soil components, nutrients and moisture content. In this paper we develop a complete system integrating sensors, GIS, Internet of Things and cloud computing. This approach allows to automate fine-grained the consumption of water without decreasing the yield. In addition to that, the collect of data and the soil moisture measurement will allow to adapt coefficient of evapotranspiration to local weather without having to resort to lysimetric measures. The proposed architecture allows to store and treat real-time, time series data and low-priority data such as 3D images used in digital phenotyping field which are treated with batch processing.

As potentially our nearest rocky exoplanet, Proxima b represents a formidable opportunity for exoplanet science and possibly astrobiology. With an angular separation of only 35 mas (or 0.05 AU) from its hosts star, Proxima b is however hardly observable with current imaging telescopes and future space-based coronagraphs. To separate the photons of the planet from those of its hosts star, a solution is to use an interferometer that can easily resolve such spatial scales. In addition, its proximity to Earth and its favorable contrast with its host M dwarf (10^-5 at 10 microns) makes it an ideal target for a space-based nulling interferometer with relatively small apertures. In this talk, we present the main observational challenges to overcome in order to study the atmospheric composition of this planet and review what will be possible with current and/or planned facilities. Then, we describe the concept of a space-based infrared (5-20 microns) interferometer with relatively small apertures (smaller than 1m in diameter) that can measure key details of Proxima b, such as its size, temperature, climate structure, as well as the presence of important atmospheric molecules such as H2O, CO2, O3, NH3, and CH4. Finally, we illustrate the concept by showing realistic observations using synthetic spectra of Proxima b computed with coupled climate chemistry models. [less ▲]

Given a video sequence captured from a static viewpoint, the stationary background initialization problem consists in generating a unique image estimating the stationary background of the sequence (i.e. the set of elements which are motionless throughout the sequence). Generating an estimation of the background is helpful, and sometimes crucial for many applications including video surveillance, segmentation, compression, inpainting, privacy protection, and computational photography. The aim of this talk is to first introduce the background initialization field by presenting the main challenges, some important methods, and the evaluation framework. Second, LaBGen, which emerged as the best method during the Scene Background Modeling and Initialization (SBMI 2015) workshop and IEEE Scene Background Modeling Contest (SBMC 2016), will be presented in depth.

Pourquoi sommes-nous aujourd'hui entourés par un seul groupe de mammifères carnassiers (les Carnivora), alors qu'au moins trois autres groupes de mammifères placentaires (Hyaenodonta, Mesonychia, Oxyaenidae) étaient en compétition avec les carnivores il y a 50 millions d'années ? Ces quatre groupes de mammifères partagent une caractéristique importante: la présence de dents spécialisées dédiées à la « découpe » de la viande, les dents carnassières. Traditionnellement, leur présence/absence ainsi que leur position dans la mâchoire ont été considérées comme des caractéristiques cruciales pour discriminer les différents groupes de mammifères carnassiers. Depuis les années 1990, les paléontologues ont étudié en détail le succès des carnivores ainsi que leurs adaptations clés. Il est ainsi apparu que les Carnivora ont surpassé, en Amérique du Nord, les Hyaenodonta, les Mesonychia et les Oxyaenidae durant l'Éocène, en particulier aux alentours de 50 millions d'années, lorsque les carnivores ont augmenté en nombre et se sont diversifiés. Des études portant sur l'écomorphologie des mammifères carnassiers ont révélé que les carnivores ont vraisemblablement réussi grâce à la position antérieure des dents carnassières par rapport aux autres mammifères carnassiers. Il a en effet été suggéré que le succès de l'évolution des carnivores pouvait résulter de la vaste gamme d'adaptations dentaires (c'est-à-dire une grande variété de régimes) conférée par cette position particulière de leurs dents carnassières. Afin de tester cette hypothèse, nous avons analysé la richesse spécifique des mammifères carnassiers européens ainsi que l’évolution de leur masse corporelle durant le Paléogène. Étonnamment, notre enquête suggère que les résultats de cette compétition sont diamétralement opposés en Amérique du Nord et en Europe : les carnivores ne se sont pas « imposés » en Europe dès l'Éocène inférieur. Il ressort, en outre, que la « Grande Coupure de Stehlin » marque, en Europe, le début de la domination des carnivores sur les autres mammifères carnassiers. [less ▲]

Comparing climate reconstructions based on proxy data approach with climate modelling enables to test both assumptions underlying the interpretation of climate reconstructions and to refine predictive models. Among geological archives, speleothems (secondary carbonate deposits in caves) and peatbogs are now regarded as important archives of past climatic and environmental conditions on the continents, offering a number of advantages relative to other continental archives (such as lake sediments, tree rings, ice cores). Both archives, presented in Belgium, are reliable continental environmental archives of high interest due to their dating possibilities and their possibility to preserve multi-proxy records of environmental and climatic dynamics. Combining studies on speleothems and peatbogs from the same area was provided an age-constrained reconstruction of climatic variability at decennial resolution for key intervals of the Holocene (6.5 to 5.5 ka, 5.2 to 4.2 ka and 3.2 to 2.2 ka). The reconstructed precipitation and temperature curves in NW European settings, as proposed in HOPES, are essential to better constrain the Northern Hemisphere climatic record and to test climate models. Our strategy was derived from a comparative study of two continental archives: speleothems and peatbogs. Time series of elemental and stable isotope geochemistry were established for the 2 archives. Precipitation and humidity conditions over Belgium was reconstructed by integration of results derived from the two continental archives. Such comparison allows to reduce the bias related to the specific sensitivity to climate changes of each archive. Time-series was first screened using classical time-series analysis techniques in order to detect potential quasi-periodic patterns in the paleoclimate records. As a second step, statistical modeling will be developed to associate peatbog and speleothem data in a single, consistent framework at the Belgian scale, and then to associate these data into larger data network. Our data will thus complement the information on rapid climate change and regional variability across Europe gained through research programs funded by the European Science Fundation and the European commission like Holivar (www.esf.org), ACCROTELM (www2.glos.ac.uk/accrotelm/) or Past4Future (www.past4future.eu).

Aims: SNOT-22 was initially designed for rhinosinusitis, but was recenty validated in various nose conditions. Nose or sinus complaint is a common cause of consultation in primary care or ENT clinic. Therefore we sought to optimize the simple and versatile instrument SNOT-22. Our aim was to determine the outcome of patients and healthy volunteers solely based on the pattern of the baseline SNOT-22 in a multi-centre study. Methods: Sixty-six healthy volunteers and 383 patients presenting to the rhinology clinic of the ENT academic departments of Godinne, Liege and Brussels participated in this study. SNOT-22 from all participants were collected blindly prior to diagnosis. Participants were then categorized in 5 groups according to their outcome: control, medical rhinologic condition, sinus surgery, functional nose surgery. SNOT-22 items relevant to each group were determined by multinomial logistic regression. Results: Control subjects showed the lowest SNOT-22 scores for all items. Medical rhinologic patients had lower scores than surgical patients. Patients requiring sinus surgery and those listed for nose surgery exhibited a specific pattern of SNOT-22 score. Most relevant items were #1 need to blow nose, #5 post-nasal discharge, #6 thick nasal discharge, #10 facial pain and #21 sense of smell. Conclusions: Distinct SNOT-22 patterns were correlated to subjects outcome. SNOT-22 was able to differentiate patients from controls, to score severity, and could further provide an accurate description of pathology. Baseline SNOT-22 could localize pathology in the sinus or in the nose and predict the need for surgical treatment. [less ▲]

Aims: Increasing pressure to reduce healthcare cost threatens the provision of acute ENT coverage round the clock. Our goal was to audit our emergency rhinologic activity over a one-month period. Methods: A prospective audit for all emergency ENT referrals was carried out from May 1st to May 31th 2017. Descriptive statistics were produced for age, sex, origin, time of arrival, diagnosis and outcome. A specific subgroup analysis was performed for rhinologic emergencies. A basic cost analysis was ran. Results: Over the study period, 190 patients were referred to the ENT emergency service. Twenty percent patients presented with nose or sinus complaint (36.8% with otological or neuro-vestibular primary complaint, 43.2% with laryngeal or neck complaint). Nose and throat complaints were more likely to present at night or on weekends. Ear complaints were more likely to present during business hours. Rhinologic complaint was more likely to require technical or surgical management than ear or throat complaint. Patients with nose complaint required minor procedure in 43.2% cases (35.6% of the total minor procedures), and required surgical procedure in 13.5% cases. Among the total ENT emergency surgical procedures, 62.5% were rhinologic ones, involving the nose (50%) or the sinus (12.5%). Ear or throat initial complaint were more likely to require no treatment or ambulatory management. Conclusion: The emergency rhinologic activity is justified in our hospital. An initial rhinological complaint was more likely to require specific ENT management than other complaints. ENT cover is an efficient service provision, especially for rhinologic emergencies.

Si la majorité des histoires sur les piranhas sont généralement sanglantes et exagérées, elles reposent néanmoins sur un trait de caractère : la force développée par leurs mâchoires pendant la prise de nourriture est réellement exceptionnelle. Il a en effet été avancé que les piranhas noirs (Serrasalmus rhombeus) peuvent exercer une force de morsure très importante puisque, à taille égale, elle serait trois fois plus puissante que celle des grands requins blancs. Cette force ne serait pas le seul apanage des piranhas mangeurs de chair, car une force importante semble aussi requise chez les espèces-sœurs herbivores pour pouvoir casser les coquilles des graines et des fruits dont elles se nourrissent. La force développée par les mâchoires de ces herbivores pendant la prise de nourriture n’a cependant jamais été étudiée, ni comparée avec celle des piranhas carnivores. L’objectif de ce travail de recherche est de mesurer des forces de morsure chez diverses espèces de Serrasalmidae et de comparer le système de prise de nourriture des deux régimes alimentaires (carnivore vs herbivore). Différentes approches ont été réalisées. (1) Des forces de morsure ont été mesurées in-vivo chez quatorze espèces de poissons Serrasalmidae (7 espèces carnivores vs 7 espèces herbivores) à l’aide d’un transducteur de force piézo-électrique. (2) Des forces de morsure théoriques ont été calculées à partir de la section transversale du muscle adducteur associé aux mâchoires. (3) La morphologie du muscle adducteur de la mandibule et la forme de la mâchoire inférieure ont été examinées chez ces mêmes espèces via des méthodes de dissection et de morphométrie géométrique. (4) Pour la mâchoire inférieure, des rapports de bras de levier ont été estimés pour déterminer et comparer le mode de transmission des forces de morsure. Quelle que soit l’approche envisagée, les espèces carnivores ont une valeur de force de morsure significativement plus élevée que celle des espèces herbivores de même taille et même masse. Le muscle adducteur de la mandibule est d’ailleurs beaucoup plus développé chez les espèces carnivores (1.5% de la masse totale du corps) par rapport aux espèces herbivores (0.4%). De plus, les carnivores ont une forme de mâchoire inférieure distincte de celle de leurs cousins herbivores. La mandibule des espèces carnivores est plus allongée avec un plus grand nombre de dents disposées sur une structure dentigère plus grande. La mandibule possède aussi un os articulaire réduit. Cette forme amène l’alignement de l’articulation « carré-articulaire » sur la ligne d’occlusion des dents. Par conséquent, la mâchoire des piranhas présente des points de ressemblance avec une paire de ciseaux. Les espèces herbivores ont par contre un os articulaire plus grand et plus large qui modifie la morphologie de la mâchoire inférieure avec le positionnement des dents au niveau antérieur. Le système de prise de nourriture rencontré chez les herbivores se rapproche de celui d’un étau. [less ▲]
