Objective: in this research, we studied changings and modulations of alexithymia [defined by Difficulties in Identifying Feelings (DIF); in Discussing Feelings (DDF) and by an Externally-Oriented Thinking (EOT)]. The purpose was to investigate if Day Psychiatric Hospitalization (DPH) could promote significant improvements on difficulties linked to alexithymia in a population of mood disorders patients (N = 73). Methods & results: a first study showed significant reductions of alexithymia scores. Considered as a personality trait, alexithymia’s changings lead us to promote the relative stability hypothesis, by displaying that moderate to high correlational levels were achieved. A second study revealed the variables impacting significantly on alexithymia. The selected variables were: demographic (i.e. gender; age; number of days of treatment); MMPI-2 variables; and perceived social support (assessed with the MSPSS scale). We found notably a positive effect of perceived social support (PSS) that reduced difficulties associated to alexithymia and other variables that increased alexithymia levels (e.g. antisocial practices, negative attitude to treatment). Conclusion: positive effects of PSS are well known and two main hypotheses were already proposed to explain its effect: PSS acting directly or as a buffer on stressful events. In conclusion, at the one hand, we showed that it is possible to significantly decrease at a certain level a phenomenon such as alexithymia. At the other hand, we enlightened significant modulators of alexithymia that might help therapists to promote or avoid specific aspects for patients involved in a recovery process. [less ▲]

Between 30.000 and 28.000 BP, the material culture of European hunter-gatherers societies is affected by a series of modifications leading to the development of new technical and symbolic traits commonly labelled as “Gravettian”. The Gravettian period display a very broad distribution of these traits, whether in terms of geography or in terms of chronology. Their adoption, and the consecutive disappearance of those prevailing during the Aurignacian, is still largely debated. Several hypotheses are considered, going from a diffusion process coming from Central Europe, to a simultaneous development of the Gravettian in various areas across Europe. To address such question, regions like Central Europe and South-West France play a major role because of numerous sites offering reliable data. North-western Europe, on the contrary, is characterized by the scarcity of well-documented sites, a situation that also characterise the EUP in general in this region. Stratigraphic sequences, especially those of Belgium, are also problematic because of a long history of research starting in the 19th century. However, a limited number of open-air sites dated to the early phase of the Gravettian period, reunite the conditions for an extensive study of Early Gravettian technical behaviours: Maisières-Canal (Province of Hainaut, Belgium), Ormesson – Les Bossats (Seine-et-Marne, France) and, to a lesser extent, Station de l’Hermitage (Province of Liège, Belgium). The study of the lithic industries recovered at these sites, suggest that the appearance of the Gravettian was a progressive process in North-western Europe, taking place between 28.000 and 26.000 BP, and involving the development of at least one specific technical tradition. This tradition diverges from the usual Early Gravettian industries on technological, typological and functional grounds. Therefore, we intend to show that, despite the overall poverty of the data regarding the EUP in North-West Europe, this territory can nonetheless participate significantly to the reflections on the developmental process of the Gravettian.

As Frank O’Hara mentions, “[i]n past times there was nature and there was human nature; because of the ferocity of modern life, man and nature have become one” (1971). However, this statement is wrong as nature has, in fact, never been ‘neutral’, independent of human influence but has instead always been depicted and defined by humans. In the age of the Anthropocene, numerous are the ways of reconsidering our relationship with our physical environment and reframing the pastoral mode so that it would best illustrate the interconnectedness between the human and the non-human. For example, Joshua Corey recently proposed an analysis of “postmodern pastoral poetry” in order to “enter this [very] zone of the pastoral”, meaning “the vision of humanity undivided from nature” (2012). Nevertheless, Corey is himself with several other famous literary critics, or more specifically ecocritics, “part of this [ ] movement that seeks to define a pastoral that has avoided the traps of idealisation [or pastoral sentimentalism] in seeking a discourse that can both celebrate and take some responsibility for nature without false consciousness” or, in other words, a more ecocentric repossession of pastoral that Terry Gifford defines as “post-pastoral”. In this paper, my purpose is to analyse US post-pastoral non-fiction, mainly memoirs and essays that include a pastoral retreat in the natural landscape, to demonstrate the importance of relating humans to the natural landscape but also to the technological and toxic landscapes. In order to do so, I intend to use the concept of the toxic sublime and to revalue it as a new perspective in the study of the relationship between American literature and our physical environment.

Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of synthetic organic chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented. [less ▲]

Le triangle de Pascal classique ainsi que le triangle de Sierpiński sont des objets largement étudiés. Ils montrent des aspects auto-similaires et ont des liens avec les systèmes dynamiques, les automates cellulaires, la théorie des nombres et les suites dites automatiques. Dans ce séminaire, nous présentons un travail en collaboration avec Julien Leroy et Michel Rigo. Dans un premier temps, nous introduisons une généralisation du triangle de Pascal basée sur les coefficients binomiaux de mots finis et nous étudions le cas plus particulier des représentations en base 2. Ces coefficients comptent le nombre de fois qu’un mot fini apparaît comme sous-suite d’un autre mot fini. De la même façon que le triangle de Sierpiński peut être construit comme l’ensemble limite, pour la distance de Hausdorff, d’une suite convergente de compacts renormalisés extraits du triangle de Pascal classique modulo 2, nous décrivons et étudions les premières propriétés du sous-ensemble de [0, 1] × [0, 1] associé à ce triangle de Pascal généralisé modulo un nombre premier p. Dans un second temps, nous étudions la suite qui compte, sur chaque ligne du triangle de Pascal généralisé en base 2, le nombre de coefficients binomiaux strictement positifs. Cette suite présente une régularité étonnante qui peut être mise en évidence en utilisant une structure particulière de graphes, appelée arbre des sous-mots. [less ▲]

In this presentation, I briefly review current practices in different countries (e.g. USA, Belgium) concerning the interim storage of intermediate and high-level radioactive waste. Drawing on ongoing research within the Programme for the Integration of Social Aspects into nuclear research (PISA) at the Belgian Nuclear Research Centre SCK-CEN, I provide a definition of interim storage and outline a possible research agenda for this area. Interim storage is defined as the stowing of high-level radioactive waste in temporary facilities for an indefinite period, until a more permanent solution is established. As the large majority of countries still has decades, if not centuries, to go before geological disposal facilities become operational, the notions of “temporary” and “interim” cover immense timespans that remain unaccounted for by scientists, technologists, regulators, implementers, and policy makers. It is therefore worth asking the following research questions: Which social, legal, and ethical considerations come into play when the concepts of “temporary” and “interim” are stretched? How do social, legal, and technical considerations interact with regard to (prolonged) interim storage facility safety? The outputs of this line of investigation are relevant to all actors involved in radioactive waste management, including governments, waste management organisations, civil society, and wider publics.

A la luz de tres de estas ficciones fantásticas modernas articuladas en torno a sus propios autores, explicamos por qué, en nuestra opinión, el efecto que producen en el lector (implícito) difiere del miedo.

Writer-musicians in translation, or how to deal with artistic hybridity? The case of Leonard Cohen. Amazon.com is just one of the many websites that has a separate category for writer-musicians in its books section: singers who are also authors – or vice versa. Leonard Cohen, Patti Smith, Ry Cooder, Nick Cave and Bob Dylan are just a few examples, and while they tend to be known and recognised as musicians, their literary works are generally well-received and translated into a number of languages. To what extent are the different mediums treated differently; are separate translation strategies employed; do literary and musical institutions elbow each other out the way when it comes to the reception and creation of a translation? Leonard Cohen is an example par excellence. France saw not only his (complete) literary works translated into French, but also many of his albums. That is notable, as Susam-Saraeva has previously argued that popular music is generally not translated. Using a discourse analysis of reviews and critical writings on Cohen in the French media (Rock et Folk, Pop Music, Extra, etc.) from the early 1970 (which was when his career as a singer truly skyrocketed in France and the rest of Western Europe), I will determine which arguments were used to justify both the initiative to translate his work as well as the various translation strategies (Franzon 2008). This line of argumentation is then compared with a number of other translations. For some songs – which were often first released as poems – there were even different translations in circulation. Secondly, I shall compare these findings to a more recent body of work – the reception and translation of his collection of poems, Book of Longing (2006) [Le Livre du Désir] and the album Ten New Songs (2001). The album was a compilation of a selection of poems from Book of Longing that Cohen set to music. In France all the lyrics were translated and included on the album’s insert. Using this quasi-simultaneous double-translation, I shall assess how the same text was translated and received in the musical and literary systems (in France) and whether the politics of translation with respect to Cohen’s work has changed over the years.

Introduction: Spectroscopic and polarimetric observations are of fundamental importance in order to derive information about the surface properties of asteroids. In 2006, the asteroid (234) Barbara was found to possess a pecular polarimetric response characterized by an abnormaly large value of the inversion angle. Later on, several other similar asteroids were discovered. They were called Barbarian asteroids in reference to (234) Barbara. Spectroscopically, all the Barbarian asteroids belong to the L, Ld and in a few cases K types in the Bus and Binzel visible taxonomy. When a classification extended to near-infrared is considered, all those known to date group into the L class. The most commonly accepted explanation for the polarimetric anomaly is the high abundance of Spinel-bearing, fluffy (type A) CAIs (Calcium-Aluminium rich Inclusion) whose optical properties could reproduce the observed polarimetry. If this hypothesis is confirmed, Barbarian asteroids could contain an anomalous amount of the first minerals condensed after the formation of the Solar system. Based on these motivations, we organized a systematic campaign of spectroscopy and polarimetry of Barbarians/L-type asteroids. Observations: 35 asteroids were observed using spectroscopy or polarimetry, or both. These asteroids include members of Watsonia, Henan and Klumpkea families which are known to be made of Barbarian and/or L type asteroids. The polarimetric data were obtained with the ToPol instrument at the Calern station of the Observatoire de la Côte d’Azur. The spectroscopic data were obtained at the IRTF NASA facility. Data analysis: The phase-polarization curve of the polarimetric data was analysed to derive the inversion angle of the asteroids. The spectroscopic data were analysed using a Hapke spectral mixing model. This method combines end-member spectra in order to fit the asteroid spectrum and derive its composition. The end-members used are the Allende matrix from which CAIs were removed, MgO rich olivine, and fluffy type A CAI. A Hapke space-weathering model was used in order to simulate the space-weathering effect on the spectra of asteroids. Results: The polarimetric data allowed us to discover 3 new Barbarian asteroids and to remove 4 asteroids from the Barbarian candidate list. We found that the inversion angle of Barbarian asteroids ranges from 26° to 30°. High CAI abundances ranging from 5 to 50% were found in L type asteroid spectra. We find for the first time a link between the abundance of CAIs and the polarimetric response. Spaceweathering also appears to play a role in polarimetry, showing an aging effect on the granularity of the surface regolith. [less ▲]

Based on a corpus of texts that are used to teach seminars in translation into the foreign language, the present paper argues that for future translators good reading skills are almost as important as high-level proficiency in both languages. The corpus comprises texts that share a common topic (travelling) but differ in terms of genre, so that the specific characteristics of each text can be described in relation to the other component texts rather than to abstract text types included in text typologies. The exercises in the seminars, before actually starting to translate, aimed at reading a text at different levels, i.e. the text as a whole, its discursive dynamics, and its component parts, while trying to connect it to the other texts included in the corpus. The preparatory exploration of the source text as well as the actual process of translation can be conceptualized as the Game of the Goose (or Snakes and Ladders): translators have to find their way through the text, taking advantage from short cuts and anticipating pitfalls they already know from past experiences.

The last eruption of Mt Fuji (Japan) occurred in A.D. 1707. The eruption lasted 16 days from 16 December 1707 to 1 January 1708 (Tsuya, 1955) and 1.8 km3 of volcanic materials were ejected in total (Miyaji et al., 2011). Lake Yamanaka, a very shallow lake (max. 14. 3 m depth) located at the foot of the east-north-eastern flank of Mt Fuji, was heavily impacted by the eruption. A thick scoria layer entirely covered the catchment of Lake Yamanaka. The thickness of the deposit varies from 5 to 37 cm around Lake Yamanaka and reaches up to 149 cm at the south-west extremity of the catchment (Miyaji et al., 2011). In order to study the influence of Hoei eruption on Lake Yamanaka, 5 gravity cores were taken during the 2014 QuakeRecNankai campaign. The Hoei scoria was present at the bottom of the one core and in the core catcher of the four other cores. High resolution magnetic susceptibility, XRD, XRF, LOI, C/N and 210Pb/137Cs analyses were performed on the gravity cores. The results shows three distinct periods of sedimentation: (1) From Hoei eruption to A.D. 1900; (2) From A.D. 1900 to A.D. 1990; (3) From A.D. 1990 to A.D. 2014. The first period is characterized by a very low sedimentation rate (~0.07 cm/yr). During this period, the sediments of the catchment were trapped below the thick Hoei scoria layer. However, peaks of terrigenous input are recorded. We link such detrical signals with violent typhoons that hit the Fuji Five Lakes region. The water from the heavy rains percolated through the porous thick scoria layer and saturated it. As a result, surface runoffs carried the sediments from the catchment into Lake Yamanaka. The second period (from A.D. 1900 to A.D. 1990) is defined by an increase of the sedimentation rate (~0.16 cm/yr). The development of soil and the agriculture (e.g. pastureland, rice field, mulberry plantations) reduced the impact of Hoei scoria. The terrigenous inputs are higher than previously but remained more or less constant during this period of time. As the thickness of the scoria layer is partially reduced or covered by new soil, rains triggered by smaller typhoons could drain the sediments from watershed and transport them into the lake. The most recent period representing the last 27 years is characterized by a very high sedimentation rate (~1.036 cm/yr). The transition between period 2 and period 3 corresponds to the development of mass tourism and the urbanization around Lake Yamanaka. It is marked by an increasing of atmospheric pollution (Pb, Zn). In the upper part of the cores, a peak of 137Cs is observed. Such peak is related to cesium fall-out after Fukushima incident in 2011. In addition to the fingerprint of human impact, the lake also record a terrigenous signal related to the 2007 Fitow typhoon which provoked damage in the area. This study highlights the influence of eruptions and typhoons on the sedimentation of Lake Yamanaka. In the present day, the sedimentation recovery after a major eruption is accelerated by human activity. References: Miyaji N., Kan'no A., Kanamaru T., Mannen K. 2011.

Damit die Lernenden als zukünftige verantwortliche Bürger eine authentische Vision der Wissenschaft und ihrer Grenzen gewinnen, heben die Rahmen- und Lehrpläne immer mehr die Notwendigkeit hervor, sie mit wissenschaftlichen Modellen und derer Erarbeitung vertraulich zu machen. Die chemische Kinetik bietet einen günstigen Rahmen, solche Modellierungskompetenzen zu fördern. Das didaktische Ziel kann wie folgt zusammengefasst werden: Eine chemische Reaktion als das Resultat wirksamer Stöße zwischen Molekülen beschreiben, um den Einfluss verschiedener experimenteller Faktoren auf die Reaktionsgeschwindigkeit zu erklären. Dies verlangt eine Modellierung, bei der die vier Ebenen (empirisch, makroskopisch, symbolisch, mikroskopisch) des didaktischen Tetraeders von Kermen und Méheut (2009) (Chemistry Education Research and Practice, 10, 24-34) erörtert werden. In diesem Vortrag werden verschiedene Aktivitäten (z.B. Versuche über molekulare Diffusion, Einführung des Begriffes des Übergangszustandes anhand angepasster, selbstgebauter Molekülmodelle) präsentiert und didaktisch ausgewertet. Großes Gewicht wird darauf gelegt, dass die Lernenden sich der erklärenden Rolle der Modelle bewusst werden, dass ihre Autonomie gefördert wird, indem der Schwierigkeitsgrad der sogenannten Zone der nächsten Entwicklung (Wygotski) entspricht, und dass das vorgestellte didaktische Modellierungsverfahren die Denkweise der Wissenschaftler reflektiert.

The existing literature in fire engineering is mostly based on single component study of structures, as opposed to system level building performance. In current practice, fire does not need to be considered as part of the structural design of the building. The required fire protection for steel components in a building is based on prescriptive design guidelines, which are based on standard fire tests on individual structural members. In addition, the fire-structure engineering has primary focused on deterministic analysis, while the field is moving towards performance-based design in recent years. Meanwhile, the scenarios leading to a fire event and the performance of the structure at elevated temperatures involve a great level of uncertainty. This work focuses on fire-structure interaction with the objective of developing fire fragility functions that capture fire damage uncertainty for the entire building (i.e., at the system-level). A fragility function provides the probability of exceeding a damage state for a given intensity measure of a given hazard. Fire fragility functions can be developed to measure the expected losses based on performance of a building structural system, rather than a single component. Different functions can be developed for buildings with different typologies (e.g. high-rise steel building with moment resisting frame, low rise steel building with bracing). This presentation derives fragility functions based on stochastic analyses of prototype buildings. In developing the fragility functions, uncertainties in the fire model, the heat transfer model and the thermo-mechanical response should be considered; but such a large number of random variables adds to the complexity of analysis and the computational time. Based on a sensitivity analysis for steel gravity frames, this work identifies the most important input parameters to be considered as random variables when developing fire fragility functions for an entire building. The sensitivity analysis for a multi-story steel building prototype is completed considering uncertainties at the compartment and building levels. At the compartment level, uncertainty in the fire scenario, compartment geometry, applied load, thermal and mechanical properties of steel and insulating materials are considered. At the building level, the influence of fire-resistance rating, building height, and occupancy type are studied. The results of this study identify the local and global parameters needed as part of deriving system-level fire fragility functions for a steel building. [less ▲]

Cette communication compare la topographie de monastères féminins répartis sur la « dorsale catholique » reliant l’Italie à la mer du Nord. La partie nord de ce territoire (anciens États bourguignons), entre Lille et Beaune, offre un champ d’investigation pertinent, en particulier durant la guerre de Trente Ans (1618-1648), alors que les couvents féminins s’implantent massivement dans les villes, aux frontières du protestantisme. Dans ce contexte, les monastères peuvent être envisagés comme des « bastions » spirituels engagés dans l’œuvre de la Réforme catholique. Par leur allure de forteresses aux fenêtres grillagées, ils constituent une ligne défense spirituelle face à l’ennemi tout en manifestant la présence missionnaire de religieuses au cœur des villes. Ces deux aspects seront approchés d’une part, par l’analyse de la position des monastères dans le paysage urbain et le rapport des communautés à la société et, d’autre part, par l’étude de la distribution intérieure des espaces et de leur utilisation. Dans un premier temps sont présentés les objectifs de mon projet postdoctoral ainsi que son corpus (quatorze villes concentrant jusqu’à quatre congrégations féminines : annonciades célestes, visitandines, carmélites et ursulines) et ses sources. Selon l’état d’avancement de la recherche, les premiers résultats sont livrés pour les fondations à Mons. [less ▲]

This paper aims at building a critical reflection on the valuation of design experimentation in architectural research and its impact on knowledge production. These considerations are rooted in the observation of a hybrid and prospective research experience led at the University of Liège (Revisiting the apartment building 2015-2016), combining documentary research, field investigation, and a research-by-design international design studio gathering 40 architects and students in architecture. We first position the essay on the issue of harnessing design activity for the benefit of architectural research. Secondly we report on the investigation observed and the distinct knowledge production modalities involved in the project. The particular implication of the act of designing is highlighted, among other steps of the investigation, and we put forward some characteristic features of the research process. We particularly consider the different design techniques, tools and representational processes involved in four distinct architectural experimentations and their impact in the emergence of design strategies or spatial interventions. We finally open a discussion on the questions raised by the valuation of these proposals in the research, and stress the inherent tension between opening new perspectives and redefining the scope of inquiry.

Covering problems are traditional issues in mathematics. For instance, a natural covering problem in the n-dimensional euclidean space is to ask for the minimal number of identical spheres needed to cover a large volume. The same issues can be considered in graphs. The corresponding covering problem is to determine the minimal number of r-balls that can be placed in such a way that every vertex of the graph is contained in at least one of them. In this talk, we consider coverings that satisfy special multiplicity conditions, called (r,a,b)-covering codes. These codes generalizes the notion of perfect codes in graphs that correspond to tilings of the graph with r-balls. We focus our attention on the multidimensional infinite grid and discuss the periodicity of (r,a,b)-codes in this case. Finally, for the dimension 2, we determine the possible values of the constant a and b. [less ▲]

Sever fires in buildings can lead to local failures, instability, partial or total collapse of the structure. In majority of the times, fire is a secondary event, after blast or impact, while the building has experienced some damage. Examples of widely known events include the 1968 Ronan Point collapse in the UK, the 1995 Oklahoma City bombing, the World Trade Center Collapse in New York in 2001, the 2014 collapse of a building at New York’s Harlem neighborhood due to a gas explosion, and the recent 2015 collapse of a building at New York’s East Village also due to a gas explosion. The initial shock to the building can be conservatively modeled by removing an intermediate vertical supporting element (i.e. loss of load-carrying capacity in a critical element), leading to an increased span for composite floor slabs. In a lowrise building, if there is enough reinforcement throughout the slab and enough continuity and restraint, despite large deflections that will develop, the slab is capable of carrying the loads by membrane action. Fundamentally, the floor system behaves as an inverted dome structure with radial tensile forces and a compressive hoop stresses. This holds true at ambient temperature, yet a similar resisting mechanism forms during fire. Previous research and experimental work shows that fire performance of composite floor slabs can be used to reduce the fire protection requirement of the steel elements, i.e. the designer should take advantage of reserve capacity in the composite floor slab membrane action. The utilization of membrane action in the design of composite floor slabs has been used, to some extent, for mitigating collapse from single events (blast or fire only). Given that, often the initial blast is followed by a secondary fire event, this work investigates the system-level performance of low-rise damaged buildings subject to post-blast fires. The hypothesis is that, when incorporated in the design, low-rise buildings can withstand the post-blast fires through membrane action of composite floor slabs. Application of this concept, within a performance-based framework, can be used to avoid progressive collapse, or at the minimum increase fire resistance to allow for safe evacuation. This work investigates the design requirements for beam sizes, fire protection, concrete reinforcement and cover thickness to develop membrane action for a pre-defined fire resistance rating under cascading post-blast fires.

La zone d’entre-deux que constitue la Dorsale catholique semble avoir été un territoire très prisé par les nouvelles communautés féminines apparues après le Concile de Trente. Malgré un contexte particulièrement défavorable, de nombreuses communautés ont en effet choisi cette bande de terre ravagée par la Guerre de Trente Ans pour y multiplier leurs établissements. Ce phénomène résulte-t-il d’une politique d’expansion délibérée et concertée ou n’est-il que le fruit du hasard et des circonstances ? Traduit-il une volonté de conquête ou de reconquête d’espaces menacés ou perdus ou, plus pacifiquement, d’une nouvelle campagne d’évangélisation ? On examinera, dans un premier temps, les arguments avancés par les intéressées au moment de leur arrivée dans chacune des localités où elles espèrent pouvoir fonder et où il importe de se faire admettre par les autorités compétentes. On analysera ensuite la relecture que les générations suivantes feront de ces temps de fondation dans les innombrables récits qui en font mention. On tentera alors de voir alors s’il en émerge une réinterprétation marquée ou non par l’esprit d’une certaine Contre-Réforme.

Preclinical studies suggest that free access to a running wheel can attenuate the behavioural responsiveness to addictive drugs in rodents. Regarding the behavioural responsiveness to drugs, psychomotor sensitization has an integral role in the process of drug addiction in craving and relapse (Steketee and Kalivas, 2011). Free wheel-running was recently shown to be efficacious at preventing the initiation or the long-term expression of psychomotor sensitization to cocaine in mice or rats (Diaz et al., 2013; Geuzaine and Tirelli, 2014). In the present study, we investigated the neuro-functional correlates of the protection against psychomotor sensitization to cocaine afforded by free wheel-running on dopaminergic neurotransmission, using microPET imaging with [18F]Fallypride, a Dopamine 2 receptor (D2R) antagonist. We used a total of 32 female C57BL/6J mice. At 28 days of age, the mice were randomly assigned to on of the two experimental housing conditions, defined by the presence or the absence of a running wheel in the cage (pre-testing period: 6 weeks). Since mice from the two types of housing received either saline or cocaine (8 mg/kg, i.p.) during testing (9 days), a basic 2*2 factorial design was generated (two-way ANOVA). The whole experimentation lasted 85 days, included the 42-days pre-testing period and the 3 weeks (housing condition, no injection) between the testing and the long-term expression of sensitization (LTES). All mice underwent a microPET (Focus 120, Siemens) the day after the LTES. The microPET protocol consisted of a 60 min. dynamic acquisition after the injection of 10 MBq of [18F]Fallypride in the tail vein. We observe a strong attenuating effect of exercise on the expression of sensitization to cocaine (Effect Size = 2.66 at p < .001 one-tailed, N.B: Effect Size is the mean difference in standard deviation units). Regarding the microPET outcomes ([18F]Fallypride Binding Potential, BP), we have a significant increase of the [18F]Fallypride BP for the cocaine-treated mice, compared to the saline-injected mice (Effect Size = 0.78 at p = .02 one-tailed). We observe a decrease tendency of the [18F]Fallypride BP in the exercise condition compared to the sedentary condition (ES = 0.48 at p = .09 one-tailed). These findings indicate that LTES is associated with an increase of the [18F]Fallypride BP in the mouse striatum, probably reflecting an increase in postsynaptic D2R density in this region. Besides that, the protecting effect of free running on psychomotor sensitization goes together with a decrease in D2R density in the striatum of exercised mice. Those data will be augmented with identical sub-experiment. All data will be pooled together to reach a total number of 64 mice (n = 16 per group). [less ▲]

In the last fifteen years, Belgian prisons have been characterized by an increase of managerial and legal regulations. This rise of “inscribed knowledge” (Freeman & Sturdy, 2015) however leads to a sharper need of prison governors for “practical wisdom” (Chia and Holt, 2009). Firstly, because law and policy don't apply automatically, but must always be interpreted by human actors in relation to the situation. Secondly, because the increase of legal and managerial inscriptions reinforces prison governors’ more general inclinations to “satisficing” decisions (March and Simon, 1958). Drawing on four years of qualitative research with 40 Belgian prison governors, this empirically based paper analyses how they cope with complex, uncertain and ambiguous situations where neither epistemic nor technical knowledge is available. In doing so, we assume that they – at least marginally – “enact” prison organisations and prison policy (Weick, 1988). [less ▲]

Food is often source of conflict between humans and wildlife in Gabon with elephants being the worst crop-raiders and “problem animals”. Damages to crops drastically reduce income, amplifying poverty and creating a negative perception of wild animals among rural people. Using beehives has been proposed as one of the best non-lethal methods to deter elephants from crop raiding; so we experienced whether the presence of the African honey bees species Apis mellifera adansonii deterred forest elephants (Loxodonta Africana cyclotis) from feeding on fruit trees on the one hand and if local people could perform modern beekeeping. We found that beehives can be effective deterrents of crop raiding by elephants, but rural people must actively manage hives to keep them at the optimum activity level. Most interestingly, modern beekeeping benefits wild bees preservation (because local people destroy them to collect honey), agriculture through pollination and could be effectively used as a bush-meat trade alternative. We learned from those experiences that conservation is performed and assumed daily by people sharing spaces and resources with wildlife. For that we need to transfer knowledge and capacities to them in order to achieve effective long lasting conservation outcomes. We also must go beyond aspirin (symptomatic) treatments by investigating elephant crop raiding root causes with multidisciplinary ecophysiological approaches. In animals ecophysiology examines the relevance of physiological processes to social, behavioural and ecological constraints with an eco-centric view. Thus, they will help get better understanding of what lead elephant to face threats such as bees or what could explain nutritional behavior and crop selection of elephants. [less ▲]

Background For the documentation of the clinical data, the International Classification of Primary Care (ICPC-2) is used, often in conjunction with the more granular International Classification of Diseases (ICD). For retrieval of scientific bibliographic information in GP/FM, Medical Subject Headings (MeSH) are used. With over 25,000 available MeSH descriptors, indexing is not easy, and yet not all aspects of the broad field of GM/FM are covered . ICPC-2 has been developed to identify reasons for encounter, symptoms, acts performed or requested and diagnosis in daily practice: It captures clinical encounters for epidemiological research. But, it was not constructed to reflect the non-clinical aspects of the profession, such as organizational, managerial, educational, and investigational aspects. Recently, a new taxonomy of organizational aspect of GM/FM has been developed to ameliorate this situation. The purpose of this development was to provide tools to exploit modern technology in terminology for information storage and retrieval systems , such as machine learning, semantic web techniques and natural language processing (NLP). The 182 concepts identified were thoroughly described in terminology records, which are freely accessible on the web (www.hetop.eu/Q). All concept and definitions were translated into 8 languages and are available online. (http://3cgp.woncaeurope.org). A book is available in 6 languages To develop the Q-codes 1700 abstracts of GP/FM congresses have been carefully analyzed. This has been the basis of the work. As a team of the EGRPN has also analyzed 600 EGPRN abstracts and developed a taxonomy of research, I have this work has been incorporated to update the QR domain. Thus ongoing Q-Codes are based on the analysis of 2300 abstracts The most important fact is that there is a Q-Codes only if the theme has been discussed by physicians during congresses. This is a bottom-up approach which contrast with the expert approach of the authors of textbook The Q-Codes have been integrated with the clinical classification ICPC-2 into a coherent whole, under the name Core Content of General Practice and Family Medicine (3CGP), for further enhancement of medical documentation and indexing of GP/FM master thesis and congress abstracts The value of a taxonomy is determined by the quality and speed of the maintenance and updating process. This will be handled by a working group of the Wonca International Classification Committee (WICC) (www.ph3c.org/Q) already authors of ICPC-2. Aim to present the preventive aspects of the Q-codes, a taxonomy specifically directed to describe the managerial aspects of GP/FM.

Cette contribution porte un intérêt singulier à la construction de l’action publique par les intermédiaires privés et publics de l’emploi, au travers de leur mission d’accompagnement des demandeurs d’emploi. Elle porte sur l’analyse des tensions intra professionnelles qui résultent de la mise en oeuvre d’une politique d’activation, dans un contexte de gestion mixte du marché du travail, en Belgique francophone. Elle prend pour objet l’accompagnement des demandeurs d’emploi, en tant que mesure destinée à assurer la réinsertion socioprofessionnelle des demandeurs d’emploi par une lutte contre le chômage de longue durée et l’exclusion sociale (Orianne, 2006). Elle s’appuie sur recherche empirique de nature qualitative (N=233 séquences d’observation ; N=40 entretiens semi-directifs), effectuée entre janvier 2013 et juin 2014 en Fédération Wallonie-Bruxelles auprès du service public régional de l’emploi Bruxellois et d’un prestataire privé. Face à la nécessité croissante de fournir des services à un marché du travail flexible et en évolution constante, d’impérieux besoins de transparence et de modernisation des services publics de l’emploi belges sont apparus. Cette transformation de l’action publique s’est notamment apparentée à une décentralisation partielle de leurs ressources et de leurs responsabilités auprès de partenaires privés (agences d’emploi privées commerciales ou opérateurs non-marchands) afin d’assurer conjointement la réinsertion socioprofessionnelle des demandeurs d’emploi par la dispense d’un accompagnement ciblé et personnalisé (Aubert et Patry, 2004). Par cette collaboration, les opérateurs privés participent désormais activement à la construction de l’action publique par le pouvoir qu’ils détiennent via l’exercice – par délégation – des fonctions étatiques alors que jusque dans les années 80, l’État orientait, contrôlait et assurait seul la régulation du marché du travail (Muller et Surel, 1998). En échange, tant les services publics de l’emploi que les prestataires privés sont amenés, dans le cadre de leurs activités d’accompagnement, à devoir rendre des comptes sur la réalisation effective de leurs pratiques. Cette exigence d’accountability comporte un double but : être transparent et légitimer l’utilisation de l’argent public. S’inscrivant dans une sociologie de l’action publique, cette contribution tend à rendre compte que cette forme de gouvernance de l’action publique (Lascoumes et Le Galès, 2012 ; Yaya, 2005) repose sur une gestion par les procédures et sur une pression aux résultats, transformant dès lors le travail quotidien des intermédiaires de l’emploi sous couvert d’une rationalisation de l’action publique. Ce faisant, elle démontre la présence d’un conflit entre l’implémentation d’une mesure d’activation et l’évaluation de son efficacité par les pouvoirs publics. [less ▲]

L’appel au peuple contre des élites (politiques, économiques,…) constitue le cœur de la rhétorique populiste. Cependant, cette invocation du peuple, des hommes de la rue, des citoyens ordinaires n’est pas un acte strictement populiste. En effet, si la démocratie peut se définir, entre autre, comme le pouvoir au peuple, n’induit-elle pas alors un nécessaires recours à sa mobilisation ? Comment distinguer l’appel au peuple du discours populiste, d’un discours démocratique ? Plus précisément, comment pouvons-nous définir le peuple ? Et quels sont les enjeux politiques et idéologiques qui sous-tendent sa mobilisation dans la rhétorique populiste ? Pour répondre à cette interrogation, nous proposons, dans un premier temps, en nous appuyant sur la littérature scientifique, de clarifier la notion de peuple et de populisme. Dans un second temps, nous étudierons le discours politique du Front national français tout en mobilisant les apports théoriques précédemment analysés. Pour ce faire, nous concentrerons notre attention sur le programme du parti, les communications orales de ses principaux représentants ainsi que les différents éditoriaux publiés sur leurs sites internet. L’analyse est discursive. En guise de conclusion, nous reviendrons sur la classification du Front national en tant que parti populiste tout en essayant de dégager les points communs et les divergences que nous pouvons observer entre la notion de peuple telle que définie par la littérature scientifique sur la démocratie, le populisme et dans les discours du FN. À terme, nous espérons ainsi mieux comprendre la notion de peuple dans l’argumentaire frontiste ainsi que ses différents éléments constituants. [less ▲]

Revenant sur les appels à la « fierté collective », au « patriotisme économique » et au « nationalisme d’ouverture » réitérés par les derniers Ministres-Présidents à la tête de la Wallonie, la communication s’attache à montrer comment ces tentatives de revitalisation d’un sentiment d’attachement identitaire, tout en relevant des manifestations du « nationalisme banal » (M. Billig), entretiennent le déficit d’imaginaire régional, réduit au développement de la « marque Wallonie » et de sa promotion auprès de ses habitants et des investisseurs. L’insistance sur la seule valeur économique et instrumentale de la communauté, visant à améliorer la compétitivité de la région sur son marché global et intérieur, fait d’autant mieux ressortir, par contraste, la dimension narrative sous-jacente à l’imagination nationaliste, particulièrement mise en évidence dans la nouvelle économie de l’enrichissement (L. Boltanski et A. Esquerre), fondée sur la patrimonialisation et l’exploitation du passé comme gisement de valeur. Du croisement des deux axes ainsi dégagés (nationalisme de faible ou forte intensité ; recours plus ou moins appuyé au storytelling), émerge une conception élargie du nationalisme, qui en fait apparaître de nouvelles modalités et permet d’ouvrir à une autre compréhension de doctrines comme le national-libéralisme ou le projet post-national. Dans la continuité des observations de M. Billig, notre cadre d'analyse structurale tend à faire des mouvements nationalistes (au sens le plus courant du terme dans l’analyse politique) un simple cas particulier parmi d’autres modes de participation plus ordinaires, infra-conscientes et naturalisées, à la communauté nationale.

As an interdisciplinary research team, we seek to tackle one important question: what is the impact of metaphors on recipients? In this context, we propose to present two experiments we conducted that both aim at measuring the impact of metaphors on citizens’ perception of and opinion on two political issues, that is Belgian federalism, and the basic income. Our first experiment was based on a newspaper article from Le Soir (July 2013) in which Belgian federalism was compared to a Tetris game. 500 participants were distributed across four experimental conditions according to the type of input they were exposed to, i.e. no input, text and image, text only and image only. They were asked to perform three interrelated tasks: a free description task, a picture association task, and a questionnaire measuring their attitude towards Belgian federalism. The results suggest that the participants who had been exposed to the experimental text tended to frame their perception of Belgian federalism differently from the other participants. However, these results suggest that reading a text might have an influence on citizens’ representations, but they do not allow us to determine the specific role played by the Tetris metaphor. We therefore developed a follow-up experiment for which we produced two different versions of the experimental text: one version where the Tetris metaphor remained explicit and a second version where this metaphor was left out. This experiment was conducted among 600 participants distributed across 3 conditions: no input, metaphorical text and non-metaphorical text. This second design should allow us to further assess to what extent the Tetris-metaphor does in fact have an impact on citizens’ representations of Belgian federalism. Our second experiment aims at measuring to what extent metaphors might have an impact on citizens’ opinion on the idea of basic income. This experiment was conducted among 750 participants who were distributed across seven experimental conditions. For the first condition, there was no input at all. The second condition consisted of a simple text explaining in a few words what the basic income is. The third, fourth and fifth condition presented the same text, but with three different metaphors added to the text, comparing the basic income to respectively allowance money, a springboard and a base frame. The two final conditions presented a non-metaphorical version of the third, fourth and fifth condition. The results of both experiments will be the main topic of our contribution. [less ▲]

Shallow reservoirs are often used in hydraulic engineering as sediment traps or storage basins, Sedimentation within these reservoirs depends on the flow pattern, which in turn depends on the shape of the reservoir. For short rectangular reservoirs, the main jet flows straight from the inlet to the outlet with on both sides identical recirculation zones. In longer reservoirs, however, the main jet reattaches to the side of the reservoir leading to a small and a large recirculation zone. Previous studies have found an empirical geometric relation describing the switch between these two different flow patterns. In this study, we demonstrate that this switch in flow pattern coincides with a maximization of energy dissipation in the shear layer between the main jet and the recirculation zones. To show this we described the power received from the jet by the recirculation zone as the product of a fluid-fluid friction coefficient and the square of the velocity difference times the shear velocity of the recirculation zone. This power is balanced by the bottom friction of the recirculation zone. Energy dissipation in the shear layer is then determined as the difference between the power performed by the jet and the power received by the recirculation zone. In this setup, energy dissipation is maximized by optimizing the friction coefficient. We show that for short reservoir lengths, energy dissipation is higher in the case of a symmetric flow pattern, while for longer reservoir the energy dissipation is higher for asymmetric flow patterns. The simulated switch between the two flow patterns appears to be very close to the empirical relation. This suggests that the flow pattem adapts in order to maximize energy dissipation between the jet and recirculation zones. The strength of this approach lies in the fact that no detailed knowledge of small scale processes is needed, while large scale structure formation can still be predicted. [less ▲]

Juno obtained low altitude space environment measurements over Jupiter’s poles on 27 August 2016 and then again on 11 December 2016. Particle distributions were observed over the poles within the downward loss cones sufficient to power nominally observed auroral emissions and with the characteristic energies anticipated from remote spectroscopic ultra-violet auroral imaging. However, the character of the particle distributions apparently causing the most intense auroral emissions were very different from those that cause the most intense aurora at Earth and from those anticipated from prevailing models of magnetosphere-ionosphere coupling at Jupiter. The observations are highly suggestive of a predominance of a magnetic field-aligned stochastic acceleration of energetic auroral electrons rather than the more coherent acceleration processes anticipated. The Juno observations have similarities to observations observed at higher altitudes at Saturn by the Cassini mission suggesting that there may be some commonality between the magnetosphere-ionosphere couplings at these two giant planets. Here we present the Juno energetic particle observations, discuss their similarities and differences with published observations from Earth and Saturn, and deliberate on the implications of these finding for general understanding of magnetosphere-ionosphere coupling processes.

Field data for validating hydraulic models remain scarce, They are often limited to inundation extents and water marks, which provide little insights into the dynamic features of the flow in urbanized floodplains, such as the discharge partition in-between the streets and the velocity fields. To address this issue, a unique experimental setup representing a whole urban district was built in the laboratory ICube in Strasbourg and the state-of-the-art shallow- water model Wolf 2D was tested against the experimental measurements (An'ault et al, 2016), The numerical model was also used to extend and refine the analysis of the laboratory observations. The experimental model (5 m >< 5 m) represents a square urban district with a total of l4 streets of different Widths and 49 intersections (crossroads). The inflow discharge can be controlled in each street individually and the outflow discharges were measured downstream of each street. The numerical model Wolf was developed at the University of Liege and has been extensively used in flood risk research (Beckers et al, 2013, Bruwier et al. 2015, Detrembleur et al. 2015). Several lessons could be learned from this combined experimental and numerical analysis. First, we found that the discharge partition in—between the streets is primarily controlled by the street widths. Second, although the standard shallow-water equations reproduce satisfactorily tnost of the flow characteristics, adding a turbulence model improves the prediction of the shape and length of the flow recirculations in the streets. Yet, this has little influence on the discharge partition because the computed recirculation widths are hardly affected by the turbulence model. The experiments and the numerical model also show that the water depths in the streets remain fairly constant in~between two intersections, while they drop suddenly downstream of each intersection as a result of complex flow interactions at the intersections. This hints that friction has little influence on the water depths obtained in the experiments. However, tailored numerical tests demonstrate that this is a direct consequence of the distorted nature of the experimental setup. Indeed, the ratio between the water depth and the street width is close to 1 in the experiments, while it would be at least one order of magnitude lower in real-world conditions, even for extreme floods. Finally, remote sensing data, such as digital elevation models, are generally available on a regular grid, which makes it convenient to use also a Cartesian grid for hydraulic modelling, We show here that the discretization of the geometry of the buildings on such a Cartesian grid has a major influence on the modelling accuracy (overestimation of the overall flow resistance). An extended shallow-water model based on non-isotropic porosity parameters is shown to improve substantially the prediction of the discharge partition in-between the streets. It is therefore considered as a valuable tool to advance urban flood modelling in practice. From the lessons learned here, we recommend that future research focuses on the design and exploitation of a less distorted experimental model, as well as on the analysis of extra flow processes such as transient conditions and interactions between overland flow and pressurized flow in underground passages.

Uncertainties in sea-level rise projections are mostly due to uncertainties in Antarctic ice-sheet predictions (IPCC AR5 report, 2013), because key parameters related to the current state of the Antarctic ice sheet (e.g. sub-ice- shelf melting) and future climate forcing are poorly constrained. Here, we propose to improve the predictions of Antarctic ice-sheet behaviour using new uncertainty quantification methods. As opposed to ensemble modelling (Bindschadler et al., 2013) which provides a rather limited view on input and output dispersion, new stochastic methods (Le Maître and Knio, 2010) can provide deeper insight into the impact of uncertainties on complex system behaviour. Such stochastic methods usually begin with deducing a probabilistic description of input parameter uncertainties from the available data. Then, the impact of these input parameter uncertainties on output quantities is assessed by estimating the probability distribution of the outputs by means of uncertainty propagation methods such as Monte Carlo methods or stochastic expansion methods. The use of such uncertainty propagation methods in glaciology may be computationally costly because of the high computational complexity of ice-sheet models. This challenge emphasises the importance of developing reliable and computationally efficient ice-sheet models such as the f.ETISh ice-sheet model (Pattyn, 2015), a new fast thermomechanical coupled ice sheet/ice shelf model capable of handling complex and critical processes such as the marine ice-sheet instability mechanism. Here, we apply these methods to investigate the role of uncertainties in sub-ice-shelf melting, calving rates and climate projections in assessing Antarctic contribution to sea-level rise for the next centuries using the f.ETISh model. We detail the methods and show results that provide nominal values and uncertainty bounds for future sea- level rise as a reflection of the impact of the input parameter uncertainties under consideration, as well as a ranking of the input parameter uncertainties in the order of the significance of their contribution to uncertainty in future sea-level rise. In addition, we discuss how limitations posed by the available information (poorly constrained data) pose challenges that motivate our current research. [less ▲]

This presentation focuses on the role of social and management sciences researchers in enacting knowledge for social action, in the specific field of trade unionism. It draws on our experience, as researchers from two different research centres of the University of Liège2, in conducting a short-term intervention research ordered by a Belgian trade union. Our objective was to provide trade union delegates with educational and methodological support for launching a strategic reflexion on the union’s positioning regarding the challenges brought about by the digitalisation of work. We describe both the methodological framework implemented by the researchers (a questionnaire survey and focus groups) and the educational device settled by the union, which was aimed at enhancing the trade union delegates’ experience of digitalisation. This process that stimulates knowledge production and circulation is analysed on the basis of the phenomenology of knowledge defined by Freeman and Sturdy (2014). We first discuss the nature of our relationship with trade union executives who ordered the research. We particularly emphasise the role of three factors, namely trust (taming between two organizational cultures), time (strong pressure due to the preparation of the congress) and contingency (due to the lack of decision-making power of the steering committee), in (re- )framing the research project and thereby influencing knowledge production. Then, we describe the role performed by researchers as a role of methodological sifting that consists in imposing different frames on the trade union delegates’ experience of digitalisation. Ranging from « meeting frame » to questionnaires, the researchers’ sifts give different forms (inform) to delegates’ knowledge – which was inscribed in documents meant at circulating the union’s official position on digitalisation; enacted through different events as focus groups and conferences; and embodied by the union delegates who took part in the process.

Most glaciers in Svalbard (High Arctic) have been retreating and thinning since the end of the Little Ice Age in the late 19th century. As a glacier retreats, it exposes new terrestrial habitats for the colonization by pioneering (micro)organisms. Here we report on the successional trajectories of cyanobacterial communities along a 100-year deglaciation gradient in the Ebba- and Hørbyebreen glacier forefields (Petunia Bay, central Svalbard). Cyanobacterial biomass and community composition were evaluated by epifluorescence microscopy and pyrosequencing of partial 16S rRNA gene sequences. Pseudanabaenales was the most abundant order in both forefields, followed by Chroococcales, Oscillatoriales, Synechococcales, Nostocales and Gloeobacterales. Succession was characterized by a decrease in phylotype richness and a marked turnover in community structure, resulting in a separation between initial (10–20 years since deglaciation), intermediate (30–50 years), and advanced (80–100 years) communities. Community turnover was explained by a combination of temporal and environmental factors, which accounted together for 46.9% of the variation in community structure. Interestingly, phylotypes associated with initial communities were related to potentially novel taxa (i.e. <97.5% similar to sequences currently available on GenBank) and sequences predominantly restricted to polar biotopes, suggesting that the initial colonization is performed by cyanobacteria from glacial and periglacial habitats. Advanced communities, on the other hand, included genotypes with a wider geographic distribution, which are likely able to establish only after the microenvironment has been modified by pioneering taxa.

A challenging aspect for experimental modelling of fluvial dike breaching is the continuous monitoring of the transient breach geometry. In dam breaching cases induced by flow overtopping over the whole breach crest (plane erosion), a side view through a glass wall is sufficient to monitor the breach formation. This approach can be ex- tended for 3D dam breach tests (spatial erosion) ifthe glass wall is located along the breach centreline. In contrast using a side view does not apply for monitoring fluvial dike breaching, because the breach is not symmetric in this case. We present a non-intrusive, high resolution technique to record the breach development in experimental models of fluvial dikes by means of a laser profilometry (Rifai et al. 2016). Most methods used for monitoring dam and dike breaching involve the projection of a pattern (fringes, grid) on the dam or dike body and the analysis of its deformation on images recorded during the breaching (e.g., Pickett et al. 201 1, Frank and Hager 2014). A major limitation of these methods stems from reflection on the water surface, particularly in the vicinity of the breach where the free surface is irregular and rippled. This issue was addressed by Spinewine et al. (2004), who used a single laser sheet so that reflections on the water surface were strongly limited and did not hamper the accurate processing of each image. We have developed a similar laser profilometry technique tailored for laboratory experiments on fluvial dike breaching. The setup is simple and relatively low cost. It consists of a digital video camera (resolution of 1920 >< 1080 pixels at 60 frames per second) and a swiping red diode 30 mW laser that enables the projection of a laser sheet over the dike body. The 2D image coordinates of each defomied laser profile incident on the dike are transformed into 3D object coordinates using the Direct Linear Transformation (DLT) algorithm. All 3D object coordinates computed over a swiping cycle of the laser are merged to generate a cloud of points. The DLT-based image processing method uses control points and reference axes, so that no prior knowledge is needed on the position, orientation and intrinsic characteristics of the camera, nor on the laser position. Refraction of the light and laser rays across the water surface needs to be taken into account, because the dike is partially submerged during the experiments. An ad hoc correction is therefore applied using the Snell-Descartes law. For dtis purpose, planar approximations are used to describe the shape of the water surface. In the presen- tation, we will discuss the resulting uncertainty and will detail the validation of the developed method based on configurations of known geometry with various complexity. The presented laser profilometry technique allows for a rapid non-intrusive measurement of the dike geometry evolution. It is readily available for laboratory experiments and has proven its performance (Rifai et al. 2017). Further adjustments are needed for its application to cohesive dike material due to the reduced visibility resulting from the higher turbidity of water. [less ▲]

Pliosaurids are iconic marine reptiles that dominated marine ecosystems during the Jurassic and the Cretaceous. These giant predators met their demise during the early Late Cretaceous but the final chapter of their long evolutionary history remains barely documented. Prompted by the discovery of a peculiar and very well preserved new taxon from Russia, we compute the evolution of pliosaurid disparity from their Early Jurassic radiation to their Late Cretaceous extinction. Despite a patchy Early Cretaceous fossil record, we show pliosaurids reached their maximal disparity during the Hauterivian-Barremian interval, suggesting a strong Early Cretaceous recovery from the apparently low phenotypic disparity of Late Jurassic pliosaurids. By using cladistic and ecomorphological data, we show that pliosaurids have repeatedly evolved slender-snouted polycotylid-like morphologies in each of their temporal radiations (Early Jurassic, Middle Jurassic and Early Cretaceous), demonstrating a more complex evolutionary history than their traditional representation as gigantic apex predators of Mesozoic marine ecosystems suggests. The extinction of pliosaurids during the Turonian (early Late Cretaceous) appears preceded by a late Early Cretaceous contraction of their disparity, the trajectory documented in ichthyosaurs, another successful marine reptile clade that disappeared during the Cenomanian-Turonian interval.

Introduction: Patients in a minimally conscious state (MCS) have been subcategorized in MCS plus and MCS minus, respectively with and without command following capacity. Here we aim to characterize differences in MCS plus as compared to MCS minus by means of functional connectivity (FC). Method: Resting state functional magnetic resonance imagery (fMRI) was acquired in 292 MCS patients and a seed-based analysis was conducted on a convenience sample of 19 MCS patients (10 MCS plus and 9 MCS minus) and 35 healthy controls. We investigated the left and right frontoparietal networks (FPN), the auditory network and the default mode network (DMN). We employed a ROI-to-ROI analysis to investigate the inter-hemispheric connectivity and we investigated inter-group differences in grey and white matter volume by means of voxel-based morphometry. Results: We found a higher FC in MCS plus as compared to MCS minus in the left FPN, specifically between the left dorso-lateral prefrontal cortex and the left temporo-occipital fusiform cortex (TOFC). The FC of auditory network, right FPN and DMN, inter-hemispheric connectivity and structure of grey and white matter did not show differences between patients groups. Discussion: Our results suggest that the clinical sub-categorization of MCS is sustained by FC differences in a language-related executive control network. MCS plus and MCS minus patients are not differentiated by networks involved in auditory processing, perception of surroundings and internal thoughts, nor by differences in inter-hemispheric connectivity and in morphology.

Polyolefins are an inexpensive class of compounds that can be used to prepare a plethora of different materials. Poly(ethylene) is the worldwide most produced polymer and is mostly synthesised by free radical polymerisation or catalytic coordination insertion using high temperature and pressure. The controlled radical polymerisation of ethylene is very difficult to achieve because of secondary reactions of this unconjugated monomer, e.g. chain transfer and termination reactions. Cobalt-mediated radical polymerisation (CMRP) represents a solution to control its polymerisation in mild conditions: in a reversible deactivation mechanism, a cobalt complex reversibly traps the active growing chains and converts them into dormant species, avoiding side reactions and allowing for a controlled polymerisation. Using CMRP, statistical copolymers of ethylene and vinyl acetate (VAc) have been synthesised, as well as block-like and block copolymers. Furthermore, functionalisation of the α- and ω-chain ends are now possible. Polymerising a vinyl bio-based monomer using CMRP has also been investigated, with the goal of forming ethylene copolymers. The copolymerisation behaviour of this novel monomer was investigated using vinyl acetate as a model and the structure and thermal properties were analysed. The monomer is very promising and copolymerisations with ethylene are undergoing. It is expected, that these completely new and highly interesting materials may act as compatibilisers for the dispersion of natural polymers, such as cellulose, into various polymer matrices.

Projectile points have recently taken a prominent position in debates on the complexity of Paleolithic human behavior. While the appearance of hunting weapons in the archaeological record was a central element in early discussions, the debate has shifted towards the appearance of specific projecting modes. Given that the organic propulsion tools (bow, spear-thrower) are only rarely preserved, energy has been invested in experiments to explore how the projecting mode can be identified based on the analysis of stone points. These experiments usually attempt to control selected parameters in projectile use (e.g., speed, target, angle of impact), but the ballistic parameters that are used are generally based on heterogeneous and not commonly reported studies. Little research has focused on the measurement of the complete ballistic performance of prehistoric weapons. We present the first results of a systematic ballistic study that quantifies and compares different modes of propulsion. [less ▲]

La dégradation considérable de la qualité de l’eau et les utilisations concurentielles de cette ressource par tous les secteurs s’accèlèrent, notamment en région méditerranéenne. Certains pays souffrant déjà de la rareté de leurs ressources en eau seront de plus en plus menacés dans un futur proche. Cette situation de pénurie serait aggravée par les dérèglements climatiques qui menacent les ressources en eau par l’augmentation de l’évaporation des reservoirs et des plans d’eau et par la fréquence des inondatons et des sécheresses. La Tunisie fait partie des pays les plus vulnérables de la région méditerranéenne. Le pays est classé selon l’indice de Falkenmark parmi les pays en pénurie d’eau, ce qui rend la disponibilité naturelle de cette ressource insuffisante pour satisfaire une demande en hausse. En effet, selon l’organisation des nations unies pour l’alimentation et l’agriculture (FAO, 2014), les disponibilités en eau douce de la Tunisie baisseraient à 450 m3/habitant/an en 2030 et à 427 m3/habitant/an en 2050. En 2015, les apports cumulés aux barrages ont enregistré une baisse de 66% par rapport à la moyenne. Cette baisse a le plus affecté la région du Nord, forte contributrice au stockage d’eau de surface (plus de 80% des ressources en eau de surface). Le barrage Joumine était parmi les barrages les plus affectés par cette baisse enregistrant une perte de stockage de 37 Mm3 en une année, soit 30% de sa capacité utile actuelle. A cette baisse de la ressource s’associe la vulnérabilité à la pollution diffuse. En effet, le bassin versant de l’oued Joumine est un bassin versant agricole dominé par les cultures céréalières très exigeantes en intrants (192 milles tonnes d’Ammonitrate, 25,9 milles tonnes de superphosphate 45 et 82 milles tonnes de DAP pour le total des surfaces céréalières emblavées du pays) (DGPA, 2016). Dans ce travail, on estime ces apports issus des terres agricoles et évalue sa réponse face aux nombreuses pressions dans un contexte de changement climatique. La méthodologie adoptée implique, en plus des observations et prospection terrain, la représentation mathématique de la relation « pression – impact », modélisée par le logiciel PEGOPERA, outil de simulation numérique de l’écosystème rivière développé par l’Unité R&D de l’Aquapôle de l’Université de Liège. Le but étant de fournir une image de la qualité de l’eau de l’oued Joumine dans des conditions hydrologiques particulières, à un pas de temps journalier et en tout point du réseau en assurant des simulations physiquement basées avec un outil dédié au calcul déterministe des écosystèmes rivières à partir des données des débits mesurés, la température de l’eau, les insolations solaires et les rejets (Deliège et al., 2009; Deliege et al 2014 ; Grard et al 2014). La mise en place du modèle a nécessité la construction d’une base de données géographique à partir des informations relatives à l’occupation des terres et le relief, le tracé digitalisé des rivières et le découpage administratif par délégation. Des algorithmes de pré-processing PEGASE ont été appliqués pour la construction et la vérification de la topologie du réseau hydrographique, la génération des profils altimétriques des rivières et de la connectivité. Une méthode d’interfaçage a été par ailleurs définie avec le modèle agro-hydrologique SWAT en vue du calcul déterministe et explicite des apports diffus des sols tout en s’assurant de la cohérence des échelles temporelle et spatiale entre les deux modèles et des processus modélisés. Le modéle a été paramétré pour simuler l’état du systéme depuis l’année hydrologique 2015/2016 et des scénarios prospectifs sont en cours d’étude pour simuler la réponse du système dans des situations particulières, notamment les projections climatiques futures.

BACKGROUND: In Belgium, music theory teachers teach theoretical aspects of rhythm, singing and other music-related skills (such as pitch accuracy or singing in harmony) outside the regular school setting. To date, their voice use and how it may be affected by background noise have hardly been studied. OBJECTIVES: 1) to determine the relationship between music theory teachers’ vocal loading and background noise and 2) to examine if the daily number of vocal fold vibration cycles (vocal loading index, VLI) is reflected in the teachers’ auto-evaluation of their voice. METHODS: A VoxLog voice dosimeter (Sonvox) was used to monitor 13 music theory teachers for one 6-day workweek from the early morning until late evening. Parameters analysed were fundamental frequency (F0, Hz), voice sound pressure level (SPL, dB), time dose (%), noise SPL (dB), and VLI. At the end of each monitoring day, subjects evaluated their voice quality, vocal fatigue, and amount of speaking and singing voice used by means of a visual analogue scale. RESULTS: Statistical analysis revealed positive correlations between noise SPL and F0, voice SPL and time dose. Correlations were also found between VLI and auto-evaluation data: a rise in VLI accompanied a decrease in self-perceived voice quality, an increase in vocal fatigue and an increase in the perceived amount of singing and speaking voice used. CONCLUSION: Three conclusions were drawn from the results. Firstly, vocal loading measured in music theory teachers is connected to the background noise level. Secondly, a great number of vibration cycles is associated with a self-reported increase in vocal fatigue and a lower general voice quality at the end of the day. Finally, correlations between the number of vibration cycles and the self-reported amount of voice use suggest that visual analogue scales are a reliable method to evaluate daily voice use. [less ▲]

Dans cet exposé, j'analyse le cas Montjean, inscrit au cœur de la pratique fargienne. Il m’intéresse particulièrement : il est révélateur tant du projet d’Arlette Farge que de sa mise en œuvre. Une première fois appréhendé au sein d’un ouvrage – La vie fragile (Paris, Hachette, 1986) – qui annonce, en bien des lieux, la poétique de l’historienne, on le retrouve dans une étude récente qui, selon moi, condense – tout en légèreté – les outils de l’atelier fargien. J’estime, en effet, que La révolte de Mme Montjean (Paris, Albin Michel, 2016) est une sorte de manifeste qui, évidemment, ne se donne pas explicitement comme tel. Mais en la parcourant, librement, chapitre par chapitre, je montrerai que les fondamentaux de la pratique d’Arlette Farge – telle que je tente de la formaliser par le biais du paradigme visuel – y sont formulés.

Nitrous oxide (N2O) is a potent greenhouse gases that has a lifetime of 114 years in the atmosphere and a global warming potential 300 time higher than that of CO2. However there are still large uncertainties and gaps in the understanding of the N2O cycle in polar oceans and particularly associated to sea ice. Sources and sinks of N2O are therefore poorly quantified. To date, only one study by Randall et al. 2012 present N2O measurements in sea ice. They pointed out that sea ice formation and melt has the potential to generate sea-air or air-sea fluxes of N2O, respectively. The main processes (except the transport processes) involved in the N2O cycle within the aquatic environment are nitrification and denitrification. Recent observations of significant nitrification in Antarctic sea ice shed a new light on nitrogen cycle within sea ice. It has been suggested that nitrification supplies up to 70% of nitrate assimilated within Antarctic spring sea ice. Corollary, production of N2O, a by-product of nitrification, can potentially be significant. Our recent studies in Antarctic land fast ice in McMurdo Sound, confirmed this suggestion, where N2O release to the atmosphere was estimated to reach 4 µmol.m-2.yr-1. But this assessment is probably an underestimation since it only accounts for dissolved N2O while a significant amount of N2O is likely to occur in the gaseous form like N2, O2 and Ar. We will then address the new tools to measure the bulk concentration of N2O (dissolved and gaseous) in sea ice, and the production of N2O by sympagic microorganisms - what process is dominant and how much N2O is produced - based on the first time series of N2O measurement in sea ice. The determination of the isotopic composition of N2O using cavity enhanced laser absorption spectroscopy technique (Off-axis ICOS) will allow us to determine the origin of these processes. [less ▲]
