Notre objectif est de discuter des diagnostics du fonctionnement psychologique pervers et de la personnalité psychopathique. Si les versions récentes du DSM (IV et 5) ignorent ces diagnostics, la pratique clinique suggère de conserver ces deux entités présentant une finesse psychopathologique plus grande et un pouvoir discriminatif plus important que la personnalité antisociale. Nous souhaitons interroger les dimensions intrinsèquement adaptatives de ces deux entités, mais aussi relever leurs différences sur le continuum de l’adaptation. Nous chercherons, en effet, à démontrer que le principe d'adaptation est une dimension centrale et commune aux deux entités, mais qui « se joue » de façons différentes pour chacune. Le pervers est hyper-adapté à son interlocuteur tout en présentant des moments paradoxaux d'inadaptation. Le psychopathe, avec sa faculté de chosification de l'alter ego et ses compétences émotionnelles paradoxales, présente une adaptation plus solitaire. Dans une perspective inspirée des paradigmes éthologique et phénoménologique, nous tenterons de cerner les différences essentielles entre ces deux modes d’être-au-monde. [less ▲]

La distinction des perspectives en première et troisième personnes est un apport récent et décisif de la phénoménologie à la psychopathologie (Parnas, Sass & Zahavi, 2012). La perspective en troisième personne, campée par les dernières versions du DSM ou par l’evidence based medicine, consiste en l’attribution depuis une position externe de signes cliniques repérés indépendamment du ressenti exprimé par le patient. L’exemple typique de ces signes est le délire et l’hallucination du schizophrène. Ces symptômes cristallisent les difficultés qu’éprouve le sujet à se reconnaitre affecté du trouble (l’anosognosie), et ce point est considéré par les modèles dominants comme une cible thérapeutique prioritaire. La visée de ces techniques, orthopédiques et psycho-éducatives, est que le patient parvienne à « reconnaitre » sa maladie. Selon cette perspective en troisième personne, il est attendu qu’il adopte, intègre la position propre à son évaluateur, et externe à sa subjectivité intrinsèque. La démarche opposée, celle de la prise en considération d’une perspective en première personne, interroge, considère et concentre son attention sur l’expérience subjective exprimée par le patient. Si l’on reprend l’exemple princeps de la schizophrénie, ce sont la « perte de l’évidence naturelle » des choses, un « trouble du sens commun » ou un « sentiment de diminution du soi » que verbalisent les patients. Ces signes cliniques, révélant l’expérience du soi, deviennent l’élément psychopathologique structurant et mettent en évidence une manière d’être-au-monde, ici schizophrénique. Le pari de cette journée d’étude consacrée à l’anorexie est de chercher à appliquer ce passage vers une perspective compréhensive en première personne pour les sujets affectés de ce trouble. Des travaux pionniers en la matière, bien que ne se réclamant pas de la phénoménologie, sont certainement ceux du psychiatre éthologue liégeois Albert Demaret (1979). Celui-ci, suggère, de façon quelque peu déconcertante, de ne plus focaliser l’attention prioritairement sur l’aspect purement médical relatif à la perte de poids et au refus alimentaire. Le comportement qui retient particulièrement son attention est l’altruisme (souvent alimentaire), qu’il considère comme « la composante la plus fondamentale du syndrome » (p. 152). Outre le fait de révéler les composantes adaptatives du trouble, son étonnant modèle permet d’entrer en consonance avec le discours des patients anorexiques qui, bien souvent, ne perçoivent pas leur minceur (mécanisme de déni) ou expriment que leur problématique ne se situe pas, selon eux, dans leur sous-alimentation. L’anosognosie anorexique et cet effroyable tendance à se priver d’alimentation au risque de mettre sa vie en danger, si l’on ouvre la porte à la perspective en première personne – si on laisse la parole au sujet –, laissent la place à un besoin (dont l’excessivité peut être reconnue) de s’occuper des autres, de les nourrir, mais aussi une hyper-attention au regard qu’on leur porte. L’investissement émotionnel et corporel des relations est souvent présenté comme étant insatisfaisant, voire comme étant l’élément moteur de leur mal-être. Ce pas de côté de la vision omnisciente du médical, assumant une remise en cause du pouvoir de domination qu’entraine la perspective en troisième personne, se révèle être un outil psychothérapeutique tout à fait pertinent. Il désacralise le problème de l’anosognosie, remet en cause le déni (ce mécanisme devient également celui de l’entourage de l’anorexique qui ne peut percevoir le surinvestissement altruiste), et ouvre la voie à une perspective intersubjective, co-construite. Cette journée d’étude a pour ambition de mettre en lumière cette préoccupation pour l’éprouvé anorexique, évoquer les modes de communication de ces patients et laisser place au discours qu’ils ont souvent du mal à livrer. Il se révèle que les apports de disciplines comme la philosophie ou l’anthropologie, ainsi que ceux de la pratique clinique sont des détours essentiels à ce programme d’étude. Nous discuterons également du symptôme anorexique lorsqu’il est secondaire à un psychotraumatisme (quelle place cette tendance à la restriction vient combler dans l’expérience de vie du sujet traumatisé). Cette journée est ouverte tant aux praticiens de terrain et personnes intéressées par les matières cliniques qu’aux chercheurs universitaires en sciences humaines. [less ▲]

Les approches traditionnelles de la schizophrénie en psychiatrie se centrent essentiellement sur une perspective que l’on peut qualifier de perspective en « troisième personne ». Ces considérations tentent, de l’extérieur, de circonscrire les difficultés auxquelles sont confrontées les personnes affectées d’une psychopathologie. Dans le cas de la schizophrénie, les manuels insistent notamment sur les symptômes délirants et hallucinatoires – signes sur lesquels, de facto, le clinicien et le patient ne peuvent s’entendre et rencontrer une phénoménologie commune. Une autre voie d’approche, s’inscrivant dans la tradition phénoménologique, propose d’explorer les phénomènes à partir du discours et du vécu subjectif des patients – dans une perspective en « première personne ». À partir d’une recherche récemment menée, nous explorerons le vécu subjectif de six patients schizophrènes à l’aide de l’échelle EASE (Examination of Anomalous Self-Experience). Cette échelle pose des balises dans la co-construction d’une narrativité permettant l’investigation d’expériences liées aux troubles du soi. Ce choix méthodologique s’ancre dans une volonté de laisser la place à l’étonnement, de ne pas pré-penser, ou le moins possible, le recueil d’expériences. Les analyses des phénomènes décrits par les patients se nourrissent des travaux de la psychopathologie phénoménologique (Blankenburg, Minkowski, Tatossian, Stanghellini, Sass, …) et se veulent un aller-retour constant entre théorie et clinique. Dans ce contexte, nous approfondirons l’hypothèse proposée par Louis Sass selon laquelle la folie, du moins dans certaines de ses formes, pourrait dériver d’une intensification plutôt que d’un affaiblissement de la conscience. L’hyper-réflexivité schizophrénique – indiquant une focalisation explicite et réflexive sur des phénomènes a priori implicites et préréflexifs – sera particulièrement analysée à partir des descriptions recueillies. Après avoir développé, à partir des cas cliniques, cette hypothèse d’une « hyper-conscience » comme symptôme cardinal de l’expérience subjective de la schizophrénie, nous analyserons les implications du recours à la perspective en « première personne » sur la prise en charge, les modèles de soins et la manière de concevoir le rapport au monde de ces patients.

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 ▲]

In quarries, invasive plant species can slow down the installation of high conservation value vegetation. Successful management of invasive requires, at first, a quantitative assessment of invasion levels. Although European legislation has adopted an ambitious strategy against invasive species, there is still a lack of knowledge about their occurrence in quarries. The aim of this study was to evaluate occurrence rates of invasive plant species in limestone quarries throughout Wallonia (Southern Belgium) and identify high priority and emerging invasive plants for adapted management. During 2016 vegetation period, forty quarries were selected by stratified sampling, using abandoned and active quarries as strata. Within selected quarries, two-meter wide transects were established to cross all activity sectors. Transects were divided in 10x2m plots, resulting in 2% of total surface of each quarry being surveyed. Cover and number of individuals of invasive plants species were recorded in each plot. Species considered were those of Harmonia list (67 species), the reference at the Wallonia scale. More than 30 000 plots were surveyed. Results of our recent study are presented (occurrences rates by species, mean percentage cover per site). First results indicate that dominant invasive species originate from different introduction paths: (i) planted (Robinia pseudoacacia); (ii) ornamentals (Cotoneaster horizontalis) and (iii) spontaneous colonization (Senecio inaequidens) - and follow various invasion dynamics. We propose research and management methods to be directed towards limitation of top ten frequent species (e.g. Buddleia davidii, Senecio inaequidens), and to establish a detection system for the emerging invasive plants.

Semiochemicals provide a powerful way for organisms to communicate and coordinate their behaviors. But they also represent opportunities for other organisms to intercept and exploit such signals. There are now numerous examples of natural enemies eavesdropping the intraspecific communication of their prey to better locate them. Aphid natural enemies, including predators and parasitoids, frequently exhibit innate responses to chemical cues reliably associated with aphids, and there is also abundant evidence that learning of profitable chemical cues frequently occurs. Thenceforth, the efficiency of aphid natural enemies to locate their prey is mainly based on their ability to perceive and orientate toward aphid-associated semiochemicals. Aphid predators were shown to respond to different groups of aphid-related semiochemicals, including aphid-induced plant volatiles; aphid pheromones and the more recently identified bacteria-produced honeydew volatiles. These laboratory studies suggest potentially promising avenues for the deployment of aphid-associated semiochemicals for the management of these pest species. While laboratory experiments are invaluable tools for revealing mechanisms, additional field studies are however needed to test ecological relevance of the observed effects. Although it is now possible to attract naturally occurring aphid predators in a crop field using semiochemicals, future work should more fully explore the broader ecological context in which signaling occurs. The information gained from a deeper understanding of the chemical ecology of aphid-natural enemy interaction will enhance our understanding of the chemical biology and ecology of aphids, and may facilitate the design of novel control strategies.

Simulation studies are often used to compare methods to detect differential item functioning (DIF). However, comparing the performance of such methods can become complicated when the identification of DIF items relies on statistics based on pre-defined significance level or on pre-established cutoff values. DIF methods based on conceptually different approaches may therefore become incomparable in terms of summary DIF statistics such as false alarm rate or hit rate. The purpose of this talk is to overcome this analytic issue by introducing receiver operating characteristic (ROC) curves in this context. ROC curves allow for global comparison of methods’ performances by computing pairs of (false alarm, hit) rates and representing them on a common scatter plot. Several summary ROC statistics can be considered for further analysis. The application of the ROC curve methodology, together with its limitation and possible extensions, is illustrated by a simple simulation study that compares three score-based DIF methods (Mantel-Haenszel, standardization and Delta plot).

Conformity to a known distribution and sensitivity to response aberrance are desirable properties of person-fit statistics. This simulation study examined the joint and independent effects of two adjustments to the standardized log-likelihood statistic (lz): (1) correction of the negatively skewed distribution of lz (Snijders, 2001), and (2) improving the sensitivity of the statistic by employing more accurate estimates of item response probability using symmetric functions (Dimitrov and Smith, 2006). Data were simulated using three test lengths (10, 20, 30 items). Data containing misfitting response patterns were simulated using three aberrant response patterns (cheating, guessing, and inattentiveness), and three levels of aberrance (i.e., proportion of item responses affected by misfit; 10%, 30% and 50%). Data containing no simulated misfitting response patterns were also generated for each test length. Non-misfitting responses were generated using the dichotomous Rasch measurement model. For each combination of independent variables, a dataset was generated consisting of 5,000 simulees. Four fit statistics were compared: lz, lz* (Snijders adjustment), lzSYM (Dimitrov and Smith adjustment), and lzSYM* (both adjustments). Mean Type I error rates were ≤ 0.1 across all conditions. The lz* statistic produced the best control of Type I error, which was often below the nominal Type I error rate, whereas the empirical Type I error rate for the unadjusted lz statistic most closely approximated the nominal rate. In contrast, lzSYM and lzSYM* yielded empirical Type I error rates larger than the nominal rate, with the discrepancy being particularly pronounced as the length of the test decreased. As might be expected, power to detect misfitting response patterns increased with test length and with the percentage of misfitting response patterns in the sample. Both lzSYM and lzSYM* evidenced improved power in detecting misfitting response patterns compared to lz and lz*, particularly for guessing response patterns and/or on shorter (i.e., 10 item) tests.

Current psychometric research is most often supported by computer software. New research perspectives often imply intensive simulation studies to validate the tested theories or hypotheses, and therefore require accurate, fast and stable implementation. To this regards, open source programming (such as in the R language) is a promising approach allowing for flexible implementation, data generation, replication of studies, and worldwide dissemination. The purpose of this talk is to illustrate how psychometrics and open source programming (with special emphasis on the R language) can interact and contribute to each other, by means of some selected examples. Several topics will be illustrated, among others: why open source programming is (to my opinion) as important as psychometric research; why we need for stable and complete implementation of psychometric and statistical routines for research purposes (for e.g., CAT); how accurate implementation of IRT routines can lead to unexpected theoretical results; why (and how) open source software can be valued as research output. Most examples will arise from the CAT framework and the R package catR for simulating CAT patterns. [less ▲]

This paper explores the transition of informal temporary camps on the French border to a sustainable state, and discusses how local policy decisions and non-state actors worked together for the implementation of a semi-permanent exclusion system based on the refugee crisis. I observe this issue as a result of a securitization process. The securitization apparatus (speech acts and policies), produced the immobility of a group. In the other hand actors will emerge to produce mobility. When a situation is defined as a crisis, atypical actions can be employed to protect the «political community». I started from the assumption that dialectic relation between securitization and camps actors had a high impact on the projects of refugees, and so long in their mobility. This is a question of integration policies at the local level. I aim to highlight the local level relevance, where the integration is primarily implemented, and therefore local and regional context should matter as much as the national model for integration (Martiniello, 2013). In Calais, due to the lack of immigrants policies, civilians associations started to react and build informal camps, but due to recent "crisis" the Stat concentrated all refugees in a single camp, 6 kilometers from the city center, called bidonville.

La lutte contre le chômage de longue durée et l’exclusion sociale par un retour à l’emploi représentent des enjeux essentiels des politiques actives du marché du travail. C’est pourquoi, cette communication s’intéresse aux effets de l’intervention sociale sur les demandeurs d’emploi à partir de l’analyse de deux dispositifs d’activation situés en Belgique francophone : une Entreprise de Formation par le Travail et une agence de Titres-Services. Au moyen d’une étude qualitative reposant sur une soixantaine d’observations de situations d’interactions réalisée entre bénéficiaires et « travailleurs du social » (consultant, assistant social, formateur, etc.) et, d’une quarantaine d’entretiens semi-directifs, nous rendrons compte de l’action de ces deux dispositifs dans le domaine de l’insertion-socioprofessionnelle. Nous illustrerons combien, par l’articulation de politiques d’emploi à vocation universelle et de politiques particularistes destinées aux personnes les plus fragiles, ces dispositifs génèrent de véritables trappes à précarité. À terme, nous montrerons combien le maintien de ces dernières soulève la question du développement progressif d’un nouveau régime de protections, opérant a minima, voire par défaut, auprès des publics peu qualifiés face à la menace sourde que font peser le marché noir et, plus largement, l’informalité du travail.

The well-known Darwinian evolutionary theory (1859) introduced natural selection as the most important mechanism of evolutionary processes at every level from biological systems, including species, individual organisms… to molecules such as DNA or proteins. In architecture we observe similar evolution processes which lead to the development of various architectural movements and concepts from common primitive living structures. The study points out that the development of bioclimatism in architecture has followed the pattern of a natural evolutionary process in which “natural selection” is likely motivated by several factors, including resources and environment problems, and driven by different mechanisms including novel building design concepts and methods, new standards and codes, discoveries in building science and construction costs. Finally, this study investigates new motivations in the era of climate change whose effects are expected to introduce more challenges as well as more trends towards a sustainable built environment through the new concept of Eco-adaptive architecture.

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 ▲]

In humans, self and memory processes interact as evidenced by the self reference (SRE) and self reference recollection effects (SRRE). However, in patients with Alzheimer’s disease (AD), this relationship can be disrupted. This was evidenced by impaired SRE and SRRE in AD for recognition of adjectives previously judged for self-relevance, as well as recall of names of people previously linked to the self. For both materials, a qualitative impairment of the recollective experience for the self-related items was also observed in AD. A neuroimaging approach suggested that reduced SRE is related to decreased grey matter volume in the lateral prefrontal cortex (lPFC). Thus, retrieval of recent self-related memories is impaired in relation to altered high-order processes in lPFC in AD. [less ▲]

Long Abstract Inspired by the work of Lévi-Strauss (1964) aimed at identifying the relationships of mutual intelligibility underlying some social and cultural facts such as the treatment of food, this paper will focus on the materiality of cooking and eating through adopting a micro-structural approach. The ethnographic data collected during an eighteen months fieldwork conducted among a group of Moroccan women in Milan to study their cooking and eating habits will be analysed by paying particular attention to the practices and elements that made the "alphabet" of Moroccan cuisine. This means that, if we considered dishes as complex sentences which can be deciphered by people that share a same language, we could try to identify the littlest components that made them happen. Which norms regulated the combination of ingredients? Which ways of cooking described this food culture? Which gestures and embodied knowledge seemed essential to give an intelligible cultural connotation to the cooking and eating of food? Which variations were admitted? The analysis of the actors' discourses and practices will show how Lévi-Strauss approach and model to the study of foodways can meet a material culture approach and still be relevant nowadays.

In this presentation, we study an FDA-approved Type 1 diabetes mellitus (T1DM) blood glucose dynamics simulator used in the majority of the practical studies on Artificial Pancreas (AP). We show that under some physiologically plausible assumptions, the glucoregulatory system described by the model is monotone. This means that the system generates trajectories which are monotone with respect to specific changes in initial conditions and control signals. This strong property leads to many interesting observations. By using monotonicity, for example, it becomes straightforward to compute bounds on glucose concentration subject to variations in intake of carbohydrates and insulin injections. Monotonicity also rigorously justifies recent studies on fundamental limitations in glucose control. [less ▲]

Monotone systems are dynamical systems whose solutions preserve a partial order in initial conditions for all times. It stands to reason that some systems may preserve a partial order only after an initial transient. These systems are usually called eventually monotone. While monotone systems have an easy characterization in terms of the sign pattern of the Jacobian matrix (i.e. Kamke-M\"uller condition), eventually monotone systems have not been characterized in such an explicit manner. In order to provide such a characterization, we drew inspiration from the results for linear systems, where eventually monotone (positive) systems are studied using the spectral properties of the system (i.e. Perron-Frobenius property). In the case of nonlinear systems, a spectral characterization of nonlinear eventually monotone systems is not straightforward, but can be obtained in the framework of the so-called Koopman operator. Additionally, we explore connections between (eventual) monotonicity and (eventual) positivity of the Koopman semigroup. This allows to view our results as a generalization of the Perron-Frobenius theory to nonlinear dynamical systems. We consider a biologically inspired example to illustrate the applicability of eventual monotonicity. [less ▲]

All around the world, practitioners and researchers point out that people are becoming less and less physically active and adopt more and more sedentary behaviours. Such changes in the Human lifestyle could have dramatic consequences as pointed out by the ‘Designed to move’ movement (Morris, 2013). To fight against that irresistible evolution, the need of a multisectorial approach is illustrated by the complexity of the socio-ecological model (Sallis et al., 2006). It underlines the large array of variables that play in the physical activity that someone is able to integrate into his/her life. Nevertheless, school has been identified as one major pillar of the promotion of an active lifestyle (van Sluijs et al., 2007). According to the knowledge and specific competences that they acquire during their studies, physical education (PE) teachers are considered as the potential cornerstones of such action (Tappe & Burgeson, 2004). While it was traditionally focused on the development of the youth’s physical, motor, and social competences of the students, since two decades, PE is increasingly more associated to the preparation of physically educated citizens. It means that what the students learn during their PE lessons should be useful outside the school and for a lifelong term. This concept is become a determining pedagogical principle: the physical literacy (Whitehead, 2013). In parallel, PE teachers are now requested to play a role on the health of their students despite if few evidence confirm that they can be successful in influencing the future behaviours of the children/adolescents to who they teach (Green, 2014). New pedagogical approaches are proposed nowadays in order to increase the effectiveness of the PE teachers’ intervention. This is linked to another pedagogical principle: accountability. Leisure activities enter progressively in the PE curriculum. Students benefit of more experiences that they could operate in their community. This requires more partnerships between school and leisure actors in order to implement original projects. Students must learn to become autonomous and smart decision makers able to identify the way to integrate PA in their leisure. [less ▲]

Dry tropical forests are widespread in continental Africa where they account for 70-80% of forested area. Miombo is a dry forest characterized by the dominance of trees in the genera Brachystegia, Julbernardia and Isoberlinia. Dry-season fires are a characteristic feature of these forests. Fire is not a frequent natural disturbance but they originate from anthropic. The impact of fire on forest species depends on the intensity and timing in relation to plant phenology. Due to urban pressure, more than 85% of woodland forests were converted to savannahs given several degree of forest degradation in the landscape. After a disturbance, tropical forest ecosystem can return to a trajectory close to the original ecosystem. The time it takes for this ecosystem recover to its predisturbance ecological condition is termed resilience. Loss of resilience can trigger a shift to another ecological state with ecosystems that are different in species and/or that are different in their functional and structural aspects. The broad goal of our study was to examine impact of fire on resilience of miombo after human disturbances. Mosaic of the MODIS 500m burned area product from 2002 to 2012 were used to calculate return frequency of fires around Lubumbashi. Five degrees of miombo degradation have been established : no degraded forest/little disturbed (level 1), moderately degraded forest (level 2), degraded forest (level 3), severely degraded forest (level 4) et deforested (level 5). For each degree of degradation, 9 circular plots (18 m radius, 0.1ha) were established, excepted for level 4 where 8 plots were laid. Within each circular plot, all woody individuals >= 2 cm diameter at breast height (DBH) were tagged, measured (height and diameter) and identified. Tree seedlings < 2 cm DBH and of height > 20cm were also sampled and identified. Herbaceous biomass was measured. Floristic composition in level 4 corresponded to fire-tolerant species. In other degree of forest degradation, most abundant species in mature trees consisted to tolerant or semi-tolerant species. Floristic composition of regeneration in most degraded degree consisted to a mixte of miombo species and fire-tolerant species. Fire has an impact on resilience of miombo after human degradation. Level 4 corresponded to a typical floristic community of a chipya habitat, where all woody species are fire tolerant. Fire can lead degraded miombo toward an alternative stable degraded states.

L’un des mérites paradoxaux des pratiques de storytelling, que C. Salmon a contribué à faire connaître au public francophone, réside dans le crédit dont bénéficie aujourd’hui l’idée de pouvoir du récit. Cette idée place les producteurs littéraires dans une position ambivalente : perçu, d’un côté, comme une menace à leur autonomie et une atteinte au capital fictionnel dont ils sont les dépositaires légitimes, cet « art de raconter des histoires » est aussi une arme à détourner dans une entreprise de guérilla contre-narrative, voire un moyen pour la littérature de reconquérir ses pouvoirs premiers. Dans cette logique d’affrontement, on s’est cependant peu soucié, au fond, de ce que les fictions littéraires elles-mêmes avaient à dire sur le sujet : s’il est vrai que le récit est une prise sur le monde et un moyen d’emprise sur autrui, comment prennent-elles en charge ces situations ? La diffusion tant des pratiques de storytelling que de leur dénonciation ne pouvait rester sans effet sur la production littéraire. Or, le pouvoir du récit est aujourd’hui un thème régulièrement frayé par les romanciers, dans une série de textes qui présentent des convergences remarquables du point de vue des situations qu’ils décrivent. Dans Un Roman russe (2007), Emmanuel Carrère voit sa vie bouleversée pour avoir publié un récit érotique adressé à la femme qu’il aimait, décrivant les réactions de celle-ci à la lecture de son texte lors d’un voyage en train programmé par le narrateur. La même tentation démiurgique de (re)construction de la réalité par le récit habite le héros du triptyque d’Antoine Bello (Les Falsificateurs 2007 ; Les Éclaireurs 2009 ; Les Producteurs 2015), recruté par une organisation secrète, le Consortium de Falsification de la Réalité, pour laquelle il récrit littéralement l’histoire en falsifiant des archives sur la base de scénarios qui finiront par échapper à leurs créateurs, déclenchant une crise de conscience lorsque le héros découvre qu’Al-Qaïda est en réalité le produit d’une saga scénaristique qui a mal tourné. Dans La Revanche de Kevin (2015), Iegor Gran fait preuve de la même cruauté à l’égard de son protagoniste : pour dénoncer les faux-semblants du monde littéraire, Kevin H. fait lui-même œuvre d'imposture, et finit piégé par ses propres mystifications. Karoo de Steve Tesich (1998), devenu depuis sa traduction française en 2012 un véritable phénomène littéraire, participe des mêmes ressorts narratifs : écrivain raté, incapable de s’enivrer comme de montrer son affection à son fils, Saul « Doc » Karoo parachève sa propre destruction en appliquant à son existence les mêmes recettes qu’il inflige aux mauvais scénarios que Hollywood lui demande de récrire. Dans chacun de ces textes, le protagoniste peut faire siens les mots de Carrère au sujet de son récit censé « faire effraction dans le réel »: « le réel a déjoué mes plans ». Avec leurs personnages-scénaristes, mauvais démiurges châtiés par un réel plus résistant que leurs tentatives de le scripter, ces romans (d)énoncent cette modalité narrative du pouvoir que Citton appelle scénarisation, ou capacité d’agencer le comportement d’autrui à travers l’acte de narration. Mais il s’agit d’un savoir immanent à ces romans, une connaissance de la fiction sur elle-même, relevant de sa fonction cognitive. Récits conscients de l’emprise du récit, ils engagent une autre forme de réflexivité que celle des romans que la critique anglo-saxonne qualifie de « postmodernes », qui mettaient en scène leur propre fonctionnement romanesque : assumant pleinement leur statut fictionnel, ils ne jouent de la frontière entre réalité et fiction que pour mieux conforter l’idée que la réalité, bien que médiée et construite par les récits, « déborde » sans cesse. S'ils ne s'opposent pas frontalement au « Nouvel Ordre narratif », ces romans thématisent les effets perlocutoires des récits, mais surtout leur insuffisance face à la force de rappel du réel. Notre communication analysera ces dispositifs fictionnels d’un point de vue formel et socio-pragmatique. [less ▲]

Frugivores can disperse seeds in a spatially contagious pattern and generate recruitment foci (e.g. under fruiting trees). This process is increasingly explored to understand the influence of frugivores on the spatial organization of plant communities, and can also serve as a method to efficiently monitor the consequences of animal extirpation. However, there is limited evidence contrasting the influence of different frugivores taxa on the creation of recruitment foci under fruiting trees, and, similarly, on the overall composition of plant communities. Here, we aimed (i) to compare the role of hornbills and primates in creating recruitment foci, and (ii) to investigate how the presence of hornbills, primates and elephants influence the overall composition of plant recruit’s community in an anthropized forest-savanna mosaic in DR Congo. We firstly compared the community of recruits (0.5-2 m high) in 25-m² plots below hornbill-dispersed trees (Staudtia kamerunensis, N=32), primate-dispersed trees (Dialium spp., N=26), and in control plots located below other tree species (N= 4900 m²). Secondly, we considered all plots to compare the community of recruits in five sites characterized by contrasted levels of hunting and housing different seed disperser communities. Our preliminary results indicate (i) communities of recruits below hornbill-dispersed trees are significantly more dense and richer than in control plots, unlike these below primate-dispersed trees. Also, (ii) recruits in sites less affected by hunting, housing more large frugivores, including elephants, tend to belong to species with longer seeds. We conclude that hornbills generate recruitment foci under fruiting trees, which can serve as an efficient tool to monitor the ecological consequences of their extirpation. Moreover, we discuss the potential influence of the different studied frugivore taxa and the risk of their extirpation from afro-tropical forests on the composition of plant recruits’ community.

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 ▲]

Nowadays, adolescents are totally integrated into the digital generation. Tablets, smartphones, and other apps belong to their normal life while most of their teachers sometimes try yet to discover what a computer is. In physical education, several authors showed that new tools can be used during practical lessons in a way to improve the learning environment and motivation of the students. As the videotape recorder in the past, current technologies represent resources that have to be adapted to the teaching strategies and not considered as miraculous tools that will solve all problems. On the other hand, one has to consider that youth are particularly attracted by digital tools that offers a growing range of possibilities to stimulate students’ critical thinking, autonomy, and involvement. This study aimed to help a group of PE teachers to use new technologies in their classes. Considering that his colleagues and he (grades 10-12) were not effective in using new technologies, one PE teacher from a secondary school invited us to propose a series of activities in order to let them identifying a way to take benefit from available ICTs. An interactive process has been implemented in order to put the teachers in the center of their development. A four steps approach was designed: (1) identification of the perceived benefits of ICTs and of the available tools, selection of one objective and one tool (4 teachers/5); (2) organization of a focus group to identify a practical way to use the selected tool (2/3); (3) preparation of a model lesson (3/3); follow up after 6 months (3/3). For several reasons, even if interesting projects of lessons were developed, they did not have been implemented. The study underlines the difficulties that PE teachers can meet when trying to innovate. [less ▲]

Interdisciplinarité : si la recherche en bande dessinée s'est, dans une certaine mesure, constituée en discipline (associations disciplinaires, congrès et conférences, revues scientifiques, etc.), son inscription au cœur des institutions reste tributaire de l'insertion de ces recherches au sein d'autres départements et, donc, d'autres disciplines. Le cas d'ACME offre un exemple de structuration au sein de l'institution universitaire qui s'exécute autour d'un travail de rassemblement collectif interdisciplinaire, chaque membre apportant les outils méthodologiques de sa formation et de sa discipline : ACME est ainsi autant ancré dans les études littéraires que dans l'histoire de l'art ou les études en communication. Les résultats de ces recherches, comme le livre L'Association : une utopie esthétique et éditoriale1, exhibent une convergence de regards, jetant différents perspectives sur un objet commun. Le travail interdisciplinaire se situe donc à deux niveaux : à la fois dans le regard porté par le chercheur sur un objet qui n'« appartient » pas traditionnellement à la discipline à laquelle il ou elle est formé-e (transdisciplinarité), et dans les résultats concrets de publication qui unifient différentes approches disciplinaires (pluridisciplinarité). Objets d'étude et échelles d'analyse : pour permettre cette convergence de regards disciplinaires, ACME s'est rassemblé autour d'objets d'étude permettant ce genre de rassemblement, d'où le choix d'objets éditoriaux et collectifs (L'Association, Spirou) ou de questions transversales (la dissidence, l'abstraction). Ces études conjuguent plusieurs perspectives et échelles d'analyses : des propositions systémiques et englobantes aux analyses les plus fines d'œuvres singulières. Entre distant reading et close reading, le groupe ACME, par le biais de son interdisciplinarité, se livre peut-être à une forme d'entre-deux, une « mid-level reading », de la bande dessinée qui rend compte des multiples interactions entre macro- et micro-niveau. Dimension transnationale : en lien avec l'interdisciplinarité, le groupe ACME a aussi mis en avant le dialogue des langues et des traditions critiques, qui résulte en partie de l'ancrage de certains de ses membres dans des départements de langues étrangères (anglais, néerlandais). Ce choix s'est de plus concrétisé dans le bilinguisme opté pour la collection « ACME » aux Presses universitaires de Liège. Alors que les recherches en bande dessinée dans le monde francophone et anglo-saxon se déroulent encore trop souvent en parallèle et/ou dans une ignorance respective, ACME se joint ainsi à d'autres initiatives d'établir un dialogue constructif entre ces deux traditions critiques.

When studying micro-electro-mechanical systems (MEMS) made of poly-crystalline materials, as the size of the device is only one or two orders of magnitude higher than the size of the the grains, the structural properties exhibit a scatter at the macro-scale due to the existing randomness in the grain size, grain orientation, surface roughness... In order to predict the probabilistic behavior at the structural scale, the authors have recently developed a stochastic 3-scale approach [1]. In this method, stochastic volume elements (SVEs) [2] are defined by considering random grain orientations in a tessellation. For each SVE realization, a meso-scopic apparent material tensor can be obtained using the computational homogenization theory. The extracted meso-scopic apparent material tensors can then be used to defined a spatially correlated meso-scale random field, which is in turn used as input for stochastic finite element simulations. In this work we intend to study the effect of different material-related uncertainty sources on the structural behavior of vibrating micro-devices manufactured using low pressure chemical vapor deposition. First, the effect of preferred grain orientation on vibrating micro-structures is assessed. To this end, SVEs are generated so that their grain orientation distributions follow XRD measurements. Second, the effect of the roughness of the vibrating micro-structures is studied. Toward this end, SVEs, whose rough surface statistical properties follow AFM measurements, are generated. A second-order computational homogenization [3] applied on the different SVE realizations allows defining a meso-scale random field of the in-plane and out-of-plane meso-scale shell properties. Stochastic shell finite elements can then be applied to predict the MEMS probabilistic behavior. [1] V. Lucas, et al., Comp. Meth. in Appl. Mech. and Eng., 294, 141-167, 2015 [2] M.

The main goals of the paper are, first, to present the Liège Game Lab, the different studies carried out in Liège on videogames and their specificities and, secondly, question our own position in the research field. To do so, we will situate ourselves in relation to the main paradigms of game studies dominated in France by social sciences and in the world by English-speakers, with a particular attention to the domination’s concerns of a peripheral position. This paper will focus on presentation and discussion of the videogames’ study in a midsized French speaking University. The aim is, first and foremost, to question the domination’s issues related to a triple peripheral position: geographic, methodological and linguistic. - The University of Liège is indeed peripheral in Belgium, in comparison to the centrality, geographically speaking, of the Universities of Brussels and Leuven. - The main group working on videogames, in French speaking Belgium, is the LabJMV (the “Games and Virtual Worlds” Laboratory), where the anthropological and sociological perspectives are dominant, while in Liège we developed more a communicative and literary outlook. - The OMNSH (the main association about game studies in France), which could be our “natural” link to the field because of the sharing language, is also dominated by social sciences and separated by a political frontier which could be seen as a boundary. - The DIGRA (the Digital Games Research Association), at the opposite, is geographically close to us (given that they are present as a chapter in Flanders), but disconnected owing to the difference of language (they publish mainly in English, we publish mainly in French). Despite of this peripheral position and making of it a strategic observatory of the tendencies of game studies, an original research hub emerged in Liège for two years. We chose to work on objects and/or with methodological perspectives which diverge of mainstream game studies: amateur game making, videogame press, Belgian players’ uses and poetical perspective on gaming practices. Various contingencies brought together at the University of Liège several researchers working more or less directly on videogames: students’ demands to write master’s thesis on videogames, the rise of grants from funding agencies like FNRS to study this medium and the development of Digital Humanities in the University of Liège. It is time, now, to question ourselves about the situation of the game studies in the University of Liège, but also the place of this University in the international field of this discipline. In first approximation, we can postulate that this gathering of researchers generated a shared research process, whose specificities stem particularly from the triple peripheral position (geographic, methodological and linguistic) of the University of Liège in the game studies field – as explained earlier. However, we would like to discuss this hypothesis not only on our own,but publicly, in the context of an international conference. Consequently, with this paper, we aim to present our group questioning our shared position and, at the same time, to expose a comparison of our five perspectives on videogames in order to understand in what ways they match each other and in what ways they create fruitful opposition. Björn-Olav Dozo and Boris Krywicky are interested in French speaking videogame press with book history’s methods. Pierre-Yves Hurel examines amateur game design with sociological tools (the dominant methodology in French speaking game studies), but these are serving communication and political investigations. Fanny Barnabé studies the same kind of objects (players’ creative practices of “misappropriation”), but through a formal and poetic approach (she analyzes the works so produced and not the players’ activities). Julie Delbouille, at the opposite, adopted a sociological and quantitative methodology, but investigated a restricted category of gaming practices: the French speaking Belgian players. [less ▲]

Introduction From early to later age populations, regular physical activity (PA) could be considered as a key behaviour to struggle against the major health, mental, social and economic issues of the 21st century (Rippe & Angelopoulos, 2010). Among PA interventions, international scientific statements recommend an emerging approach targeting specific intergenerational dyads, such as grandparent-grandchild pairs (Marcus et al., 2006). Besides, Ory and colleagues (2003) underlined that intergenerational interactions could also combat aging stereotypes across generations. Accordingly, the aim of this study was to examine the effects of an intergenerational PA program on PA behaviours and aging stereotypes of grandparent-grandchild pairs. Methods Intergenerational grandparent-grandchild pairs were recruited in two Belgian municipalities. Those two groups took part in a three-month intergenerational intervention, adapted from a previous intervention (Mouton, Renier & Cloes, 2015) and including one weekly session of PA. Assessments were performed before (T0), during (process analysis) and after the intervention (T1). Grandparents PA was assessed with the QAPPA and the SF-36 questionnaires and with a battery of physical fitness test (SFT). The UCLA loneliness scale was also administrated to seniors. Grandchildren PA was evaluated with a seven items Likert scale. Relationship quality and ageism stereotypes between generations were assessed using a combination of existing validated instruments. Results and conclusions The intergenerational groups were composed of 14 dyads of grandparent (65±3.2 years)-grandchild (8.8±2.3 years) in one municipality and 6 dyads of grandparent (64±4.5 years)-grandchild (7.7±1.3 years) in the second. By its combination of physical and psychosocial objectives, the results of this study are expected to provide a significant and original contribution to the research field. If intergenerational PA has the potential to reduce ageism, it could pave the way to interdisciplinary interventions among physical education professionals. [less ▲]

The failure of carbon fiber reinforced composites with a quasi-isotropic sequence ([90/45/-45/90/0]S) and open-hole geometry is studied using a multiscale method [1]. On the one hand, the intra-laminar failure is captured using a damage-enhanced mean-field homogenization scheme. To this end, each ply is modeled as a homogenized material whose anisotropic damage behavior is captured from the homogenization method [2]. In order to avoid the problem of loss of solution uniqueness the mean-field homogenization process is formulated in the context of the non-local continuum damage theory [3]. On the other hand, an hybrid discontinuous Galerkin/extrinsic cohesive law method is used to model the delamination process at the ply interfaces. This hybrid method avoids the need to propagate topological changes in the mesh with the propagation of the delamination while it preserves the consistency and stability in the un-cracked interfaces. As a result, the multiscale framework allows predicting damage propagation directions in each ply along the fiber directions accordingly to the experimental results as it is demonstrated by considering an openhole [90/45/-45/90/0]S-laminate studied both numerically and experimentally.

Si les game studies se sont développées en prenant appui, dans un premier temps, sur les études littéraires et en particulier sur la narratologie (Ryan 2004, Atkins et Krzywinska 2007) pour interroger la notion de récit appliquée au jeu vidéo, elles ont ensuite fait appel à d’autres disciplines (psychologie et sociologie en particulier) pour construire leur approche de certaines notions, dont celle d’avatar qui nous paraît utile dans le cadre de recherches sur le personnage en littérature. Confrontées à des objets irréductibles à leur textualité (l’étude de la composante « play » du jeu a pris le pas sur celle du « game », surtout en francophonie – voir à ce sujet Triclot, 2011), les game studies se sont dotées d’outils et de théories propres, réélaborant pragmatiquement certaines notions à partir de théories antérieures (les « univers fictionnels », voir Barnabé, 2014) ou forgeant des concepts spécifiques (l’« impératif d’action », voir Genvo, 2005). Dans cette communication, nous souhaitons mobiliser une série de réflexions récentes sur la notion d’avatar vidéoludique pour les étendre à l’étude des personnages au sein de la littérature contemporaine.

Numerical modelling of the complete ductile failure process is still a challenge. On the one hand, continuous approaches, described by damage models, succeed in the initial diffuse damage stage but are still unable to represent physical discontinuities. On the other hand, discontinuous approaches, such as the cohesive zone models, are able to represent the crack propagation behaviour. They are suited for local damaging processes as crack initiation and propagation, and so, fail in diffuse damage prediction of ductile materials. Moreover, they do not usually capture triaxiality effects, mandatory for accurate ductile failure simulations. To describe the ductile failure process, the numerical scheme proposed here combines both approaches [1] in order to beneficiate from their respective advantages: a non-local damage model combined with an extrinsic cohesive law in a discontinuous Galerkin finite element framework. An application example of this scheme is shown on the attached figure. The initial diffuse damage stage is modelled by an implicit nonlocal damage model as suggested by [2]. Upon damage to crack transition, a cohesive band [3] is used to introduce in-plane stretch effects inside the cohesive law or in other words, a triaxiality-dependent behaviour. Indeed, these in-plane strains play an important role during the ductile failure process and have to be considered. Concretely, when crack appears in the last failure stage, all the damaging process is assumed to occur inside a thin band ahead of the crack surface. Thanks to the small but finite numerical band thickness, the strains inside this band can be obtained from the in-plane strains and from the cohesive jump. Then, the stress-state inside the band and the cohesive traction forces on the crack lips are deduced from the underlying continuum damage model. The band thickness is not a new material parameter but is computed to ensure the energetic consistency during the transition. [1] Wu L, Becker G, Noels L.

With his expression ceci tuera cela, Hugo established almost two centuries ago a strong link between words and stones as transmission vehicles of human memory. We heritage experts would be inclined to consider stones as more reliable than words, what semiology seems to confirm : stones are clues, and clues are, according to Roland Barthes, tangible proves of “what has been”. But the inspector Columbo has often shown how we can play with these clues, and Umberto Eco would easily forgive us this incursion into mass culture to agree on the idea that we can rewrite history using false justified clues, that is also, tangible heritage. Since the emergence of the restoration discipline, experts have been aware of the danger of falsification : Ruskin’s texts, Boito’s philological restoration, Brandi’s historical instance or the Venice charter are so many illustrations of this concern. But since the 1990’s in Europe, a growing number of restoration and reconstruction projects very clearly depart from this fundamental idea. Of course, the collapse of the Soviet bloc has created a particular political context in which (re-)emerging nations attempted to (re-)build their identity through architectural symbols (leading to the writing of the Riga charter). But more generally, this phenomenon is closely linked to the cultural context : on the one hand, the postmodern movement has deeply questioned the idea of “sincerity”, with a tendency to blur the limits between true and false and, as a consequence, between original and copy. And on the other hand, in the heritage sphere, the globalisation of the debate progressively rattled european certitudes about concepts as essential as authenticity, leading to the replacement of the self-confidence expressed by the Venice charter by a careful relativism, illustrated by the Nara document thirty years later. These contemporary phenomenons have important side effects. In the context of late capitalism, heritage has become a major economic issue, especially as many cities have well understood its potentialities in terms of city branding. This could of course be seen as a positive opportunity for heritage conservation ; nevertheless, a rich scientific literature has shown that tourism can deeply transform our representation of the past. The tourist is a client rather than an amateur, and his quest of authenticity is often satisfied by what the French philosopher Yves Michaud has called “adulterated authenticity”, the one from over-restored monuments, reconstructed city centres, eco-museums, and, why not, theme parks. More than authentic built remains, the “tourist gaze” shapes more and more our representation of “what has been”, and the arguments developed by heritage experts in response to globalisation and identity issues are seized upon by city marketing specialists willing to meet a mostly commercial demand, sometimes tinged with dubious political motivations. What we intend to question in this session is the limit between uses and abuses of heritage and heritage discourse and more particularly whether, as suggested by Theodore Scaltsas’ inspiring paper “Identity, origin and spatiotemporal continuity” (1981), the intentions underpinning restoration and reconstruction projects affect the very essence of restored or reconstructed objects. Besides architectural history and conservation theory, we welcome contributions in the fields of sociology, anthropology, philosophy, history, political sciences, geography, tourism economy and even psychology.

Dans son article intitulé « Traces. Racines d’un paradigme indiciaire » (1979), Carlo Ginzburg actait l’émergence progressive d’un modèle épistémologique « apparu silencieusement » à la fin du XIXe siècle, mettant l’examen des détails au centre des exigences du champ des sciences humaines. Loin d’être insignifiants ou distrayants, loin d’être considérés comme écarts ou faits marginaux, les détails ont ainsi pu acquérir un rôle central pour la description, l’interprétation et l’attribution (quel que soit le domaine d’investigation privilégié). Autrefois largement sous-estimés par l’observation, dont ils constituaient en quelque sorte les rebuts devant être abandonnés au profit d’une vision d’ensemble, les détails se sont – pour les défenseurs de ce paradigme – mués en indices permettant de reconstituer et de révéler une situation absente. À suivre ces analyses, les historiens de l’art seraient nombreux à avoir inscrit leurs travaux dans la perspective de ce paradigme indiciaire – le connaisseur d’art Giovanni Morelli étant, aux yeux de Carlo Ginzburg, l’une des figures les plus emblématiques de la priorité accordée aux détails dans l’effort d’attribution d’une œuvre à un artiste. Morelli avait pour projet de défaire les assignations trop rapides et les liens interprétatifs déjà établis par le passé, pour reprendre le travail d’identification à son tout début, concentrant son effort sur des traits sous-estimés, et faisant par là apparaître des erreurs d’attribution parfois dommageables (en dépit des moqueries dont il faisait les frais à cause de sa propension à étudier les oreilles ou les ongles). Fondée sur la sémiotique médicale (Morelli, comme Freud, comme Conan Doyle, avait une formation de médecin), la capacité de diagnostic pouvait alors servir à « remonter, à partir de faits expérimentaux apparemment négligeables, à une réalité complexe qui n’est pas directement expérimentable » . Enraciné dans les moments inauguraux décrits par Ginzburg, le paradigme indiciaire est devenu le lieu de croisement « de disciplines basées sur le déchiffrement des signes en tout genre, allant des symptômes aux écritures » . Or, parmi ces disciplines, il faut compter à n’en pas douter l’iconologie, à laquelle Ginzburg fait très peu référence dans l’article de 1979, si ce n’est à travers la citation d’ouverture, qu’il attribue à Aby Warburg : Dieu est dans les détails. Car en effet, en tant que méthode d’interprétation des artefacts visuels (essentiellement concentrée sur la peinture), l’iconologie cultive un contact rapproché avec ses objets et défend une « lecture » attentive des marques matérielles renvoyant à un contexte symbolique précis, qu’il s’agit de dégager. Le travail de l’iconologue s’inscrit par définition dans le registre du déchiffrement ; les œuvres d’art étant régulièrement assimilées à des rébus dont il faut pouvoir résoudre l’énigme . Dans cette perspective, la peinture est considérée comme accumulation de signes indiquant une valeur symbolique définie. En tant qu’approche spécifique (et volontairement limitée) de l’œuvre d’art, l’iconologie pose le problème de la signification, et interroge ce qui nous met sur la piste de la signification.

In 2003, a new multi-annual program aimed at increasing the availability of formal child care for 0-3 year old children was launched in Wallonia, the French-speaking part of Belgium. This paper is interested in evaluating if this increased availability of formal child care resultedin a higher employment rate for women with at least one child under 3. To this end, we use a difference-in-differences approach based on municipality-level panel data, taking advantage of the fact that the increase in availability of formal child care differed greatly across municipalities. We find that the raise in child care availability significantly increased the maternal employment rate, but to a lesser extent than expected, most likely because of a substantial crowding-out effect.

Hybrid organizations, social enterprises in particular, have often been described as crystallizing tensions due to the institutional pluralism they seek to integrate internally. This paper aims to identify, locate and explain the organizational tensions faced by nascent social entrepreneurial teams through a multiple-case study. The findings show that the types and patterns of tensions differ according to team size and to the strength of ties binding team members. In the specific context of social enterprises, the research discriminates between mutual interest and general interest social mission, which is identified as a factor influencing tension development. Further, the analysis suggests that tensions tend to be located within a particular logic (social welfare in this case) rather than between logics, as often suggested in the literature. As such, it contributes to the literatures on hybrid organizations and social enterprises by portraying more complex interplays between and within plural – particularly social and commercial – logics.

Fluid resuscitation is the first choice therapy for sepctic shock. However, fluid infusion only increases cardiac output in approximately 50 % of cases, while an excess of fluid can have harmful effects. Therefore, clinicians are looking for indices to predict the effect of fluid infusion on cardiac output, before giving fluid. In this work, a minimal mathematical model of the cardiovascular system is used, representing the heart, an artery and a vein. The nine model parameters, including total stressed blood volume, are identified from experimental data. The experimental data was recorded during three 500 ml fluid infusions on two pigs infected with endotoxin, to simulate septic shock. The total stressed blood volume parameter is negatively associated with the change in cardiac output after fluid infusion, as observed in previous studies. Subsequently, an algorithm is proposed to guide fluid resuscitation, based on the value of this parameter. The use of the algorithm results in 60 % less fluid being given with virtually no effect on cardiac output. The decision algorithm has the potential to be used in human clinical trials since the data required for parameter identification can be obtained in an intensive care unit. [less ▲]

The aim of this paper is to describe the variety of paratextual elements encountered in the so-called ‘Chester Beatty’ papyrus archive coming from Deir el-Medina (Western Thebes; New Kingdom). Originally, this archive consisted of over 45 different manuscripts, which passed into various hands among the Necropolis workmen of the New Kingdom during a period of more than 100 years (Černý 1945; Koenig 1981; Pestman 1982; Grandet 2002) and is now scattered among collections and museums around the world (Cairo, Dublin, Geneva, London, Oxford).After some considerations on the history of this archive — from Antiquity until its eventful discovery, both in situ within the village of Deir el-Medina and on the antiquity market between 1928 and 1935 (Posener, in Černý 1978: VI-VII) — this talk will be devoted to the formal description and functional categorization of the paratextual elements encountered in the texts of the archive. This corpus has been selected in order to limit the amount of variation possibly induced by different mediums (the texts are all written on papyrus) and by heterogeneous socio-cultural settings. On the other hand, it allows me to explore a great variety of paratextual elements used by this community across time (from the 19th dynasty until the second part of the 20th dynasty) and genres.

With its long serial history and in its various reboots, Wonder Woman has successively and/or simultaneously functioned as a super-heroic icon for feminism and as a sex symbol objectified by the “male gaze.” Her body has always been a site of contention for the complicated place of women within comics culture, and her story is not only that of DC to tell, but also that of her fans, readers, and cartoonists, who have been writing their own versions of the character. This paper zooms in on one particular instance that not only revisits the story of the character, but also its history as a cultural object. Ron Regé, Jr.'s self-published Diana is an adaptation of Marston and Peter's 1943-1944 newspaper strips retelling Wonder Woman's origin story in a highly respectful homage to its creators. Regé's Diana reads as an explicit attempt to reclaim attention for the original comics of Marston and Peter as well as the biographies of their creators: the inside covers sum up Marston's life as a psychiatrist, feminist and polyamorist, and further posits Wonder Woman as a feminist superhero that needs to be reinvigorated today. Redrawing the origin story of Wonder Woman both as fictional character and cultural object becomes for Regé an act of dissent from DC Comics's New 52 reboot and its ‘counter-feminist’ revision of the character's origin story. This act simultaneously tunes in with a sudden public attention in 2014 for the historical origins of Wonder Woman and its feminist genealogies, most notably through the success of Jill Lepore's The Secret History of Wonder Woman. By drawing from the serial archive of the character, Regé draws attention to the gendered dynamic of remembering and forgetting that underwrites the history of comics. [less ▲]

Al alloy AlSi10Mg processed by Laser Beam Melting (LBM) exhibits a much finer microstructure than its cast counterpart due to the ultra-fast cooling rates imposed in the LBM process. One important consequence of this microstructural refinement is that a classical T6 age hardening heat treatment will not have the same effect on LBM AlSi10Mg when compared with cast AlSi10Mg. Indeed, a previous study by the present authors has shown that heat treating LBM AlSi10Mg at 510°C for 6 hours followed by a second isothermal hold at 170°C for 6 hours brought a marked improvement of the yield stress by 30% and of the elongation at break by 220%. However, this was achieved at the expense of a decrease in both hardness and ultimate tensile strength. A better understanding of the underlying phenomena is needed in order to optimize the heat treatment of LBM AlSi10Mg. The present work hence aims at investigating in more depth the microstructural evolution induced upon heat treating LBM AlSi10Mg. Changes in texture as well as in the distribution of Si-rich precipitates (size, morphology...) have been studied, with a particular attention to those changes taking place during the first step of the heat treatment at the higher temperature of 510°C.
