[more ▼]Background In the Belgian health system, sickness absence (SA) management implies complementary roles for general practitioners (GPs), social insurance physicians (SIPs) and occupational physicians (OPs): GPs deliver sick notes and treatment, SIPs control SA benefits and OPs strive to adapt work environments to workers’ remaining capacities. In practice however, there is little cooperation between the three physicians. In 2009, the Ministry of Employment commissioned a study to identify GP-OP-SIP cooperation channels in order to prevent long-term work disability. Methods The study involved two phases. 1) Researchers from the three groups agreed on 15 proposals to enhance cooperation: to establish a formal contact between GP, SIP and OP for patients with > 3 months SA (n=3) ; SIP decision to end SA benefit to be forwarded to the GP (n=2) ; work-related information to be provided by the OP to GP and/or SIP (n=4); website giving contact data of GPs, SIPs, and OPs (n=2) ; initial and continuous education focusing on inter-physician cooperation (n=3); electronic data exchange when dealing with long-term SA (n=1). 2) A Delphi study was conducted in 2012 to validate these proposals: 61 experts representing professional groups of physicians (GP, SIP, OP), patients, government, employers and labor unions were asked to participate. A 18-items questionnaire (the 15 proposals and 3 open questions) was used in a 2-round Delphi study. Proposals were accepted if 80% of experts agreed. For drafting the final proposals, the research team relied on a multidisciplinary expert group. Results Participation rate was 77% (47/61 experts) in round 1 and 7 out of the 15 proposals were accepted. During round 2, participation rate was 94% (44/47); 2 of the remaining proposals reached agreement level. Public authorities were thus advised to invest in a) promotion of pre-return to work visit with the OP for sick-listed patients; b) a website with OPs contact data; c) joint guidelines for return to work guidance; d) joint training of the 3 physician groups; 5) methods ensuring safe electronic information exchange. Conclusions The need for inter-physician cooperation in disability management may exceed individual goodwill and should best be organised by public authorities. The current study may be a first step in this process. [less ▲]Detailed reference viewed: 36 (11 ULg) Le projet EpistolART et le Carteggio inedito d’artisti de Johann Willhelm Gaye.

[more ▼]Our objective is to study the pointwise regularity of functions via their multifractal spectrum. Computing the multifractal spectrum of a function using directly its definition is an unattainable goal in most of the practical cases, but there exist heuristic methods, called multifractal formalisms, which allow to estimate this spectrum and which give satisfactory results in many situations. The Frisch-Parisi conjecture, classically used and based on Besov spaces, presents two disadvantages: it can only hold for spectra that are concave and it can only yield the increasing part of spectra. Concerning the first problem, the use of S spaces allows to deal with non-concave increasing spectra. Concerning the second problem, a generalization of the Frisch-Parisi conjecture obtained by replacing the role played by wavelet coefficients by wavelet leaders allows to recover the decreasing part of concave spectra. We present a combination of both approaches to define a new formalism derived from large deviations based on statistics of wavelet leaders. We also present the associated function space.

[more ▼]As surprising as it may seem, there exist infinitely differentiable functions which are nowhere analytic. When such an unexpected object is found, a natural question is to ask whether many similar ones may exist. A classical technique is to use the Baire category theorem and the notion of residuality. This notion is purely topological and does not give any information about the measure of the set of objects satisfying such a property. In this purpose, the notion of prevalence has been introduced. Moreover, one could also wonder whether large algebraic structures of such objects can be constructed. This question is formalized by the notion of lineability. The first objective of this talk is to go further into the study of nowhere analytic functions. It is known that the set of nowhere analytic functions is residual and lineable in C^infty([0, 1]). We prove that the set of nowhere analytic functions is also prevalent in this space. Those results of genericity are then generalized using Gevrey classes, which can be seen as intermediate between the space of analytic functions and the space of infinitely differentiable functions. We also study how far such results of genericity could be extended to spaces of ultradifferentiable functions, defined using weight sequences.

[more ▼]Macaque tourism, i.e. a tourist activity focusing on wild macaques as main attraction, is an example of the bourgeoning and diversified human-macaque interactions in Southeast Asia. Although both people and macaques can benefit from their interactions at tourist sites, this activity also raises several conservation and management issues which are essential to understand in order to promote a sustainable coexistence. Using an ethnoprimatological approach, we provide here an assessment of the effect of a long-term management regime at the very popular tourist Ubud Monkey Forest in Bali, Indonesia. Over a four-month period in 2013, we characterized the visitor-macaque interactions with ethological methods and we compared our data with those collected 12 years earlier by Fuentes and colleagues. In parallel, we conducted a questionnaire survey, interviewing 99 Balinese people to assess their attitudes towards macaques and the Monkey Forest. Our results confirmed that the management efforts to reduce the aggressiveness of macaques towards visitors have been effective. Indeed, we observed a considerable reduction of the frequency and intensity of agonistic interspecies interactions. However, the interactions between macaques and visitors frequently involved close physical contact, such as during provisioning. Men on the human side, and adult or subadult males on the macaque side, were the groups the most frequently involved in these types of interaction. A reinforcement of the management practices limiting close interspecies contact interactions by targeting the most exposed groups, is therefore necessary in order to reduce the risk of pathogen cross-species transmission. Our questionnaire survey revealed globally a high level of tolerance of local people towards macaques in Ubud. These positive attitudes were determined by the economic and cultural benefits derived from the macaque presence and tourism activity, as far as they compensate for the nuisances caused by macaques. Crop raiding in cultivated fields surrounding the Monkey Forest was still a source of tension which would require further management efforts including the development of open buffer zones.

[more ▼]Le but de l’analyse multifractale est de fournir une méthode permettant d’approximer le spectre de singularités d’une fonction. En 1985, Frisch et Parisi ont proposé un premier formalisme. D'autres formalismes, basés sur les coefficients d'ondelettes, ont été introduits (ex WLM). Cependant, de part leurs natures, ces méthodes ne peuvent détecter que des spectres concaves. En 2004, Jaffard introduit les espaces Snu pour palier à ce problème. Ces espaces sont inclus dans une intersection d'espaces de Besov. Dans cet exposé, je présente une généralisation des espaces Snu. Ceux-ci sont mis en relation avec les espaces de Besov généralisés et une mise en pratique est présentée.

[more ▼]Sports are increasingly shaped by science and technology. Sportspersons now routinely operate in an environment consisting of devices, data flows, laboratories, and scientists. While governments, research industries, and many scientists across the world promote the integration of science and technology into sports as a means of inspiring innovation in sports, how this integration is achieved has not been systematically investigated. To remedy this shortcoming in science and technology studies (STS) and to grasp how science, technology, and sports are mutually attuned in everyday situations, this paper examines a sociotechnical device developed by scientists in Flanders (Belgium) popularly known as the ‘sports compass’ (sportkinelab.be/sportkompas). As the sports compass is designed to detect and develop sports talent in young children through standardized physical trials, it is used in the Flemish sports field. Drawing on ethnographic methods and on preliminary interviews with sports compass developers and users (scientists, children, parents), the paper argues that the compass’s solidity as a scientific conduit for talent is disrupted by the multiple social aims it serves (e.g. sports participation, striving for excellence) and the multiple expectations it elicits. Accordingly, multiple solidarities and shifting alliances can be discerned between technology developments and uses, devices and humans, and between research institutes, schools, and sports organizations. The paper’s findings serve to open a discussion both on the meaning and viability of talent detection among children and sportspersons, and on sports and innovation policies designed to render sports more scientific and technological.

[more ▼]Organometallic-Mediated Radical Polymerization (OMRP)1 has received renewed interest in recent years since proving its efficiency for non-activated monomers like vinylacetate (VAc), N-vinylamides, etc. Nevertheless, important mechanistic questions and challenges remained. A major goal in the field of controlled radical polymerization today consists in the design of well-defined ethylene containing (co)polymers. A recent mechanistic study on the impact of head-to-head addition on the course of the VAc polymerization by OMRP provided a strong incentive to evaluate the copolymerization of VAc with ethylene by this technique. Indeed, the latter revealed that dormant chains resulting from inverted head-to-head additions in the VAc polymerization, which mimics a terminal ethylene-cobalt moiety, reactivates at a similar rate compared to the ones resulting from the regular head-to-tail addition. As a result, well-defined statistical and block-like ethylene-based copolymers were prepared. These achievements represent an important step towards a versatile synthetic platform for polyolefine-based materials.

[more ▼]Introduction (800 caractères): Le cancer est un problème de santé majeur dont l’âge constitue un facteur de risque avéré. Paradoxalement, les personnes âgées souffrant d’un cancer sont souvent sous-traitées comparativement à des patients plus jeunes : à situation clinique équivalente, des futurs médecins recommandent moins fréquemment une reconstruction mammaire (Madan et al., 2004) et des médecins recommandent moins souvent une chimiothérapie (Protière et al., 2010) chez les personnes âgées par rapport aux jeunes. Un élément d’explication avancé par les auteurs est la stigmatisation liée à l’âge (c.à.d. nos stéréotypes liés à l’âge, et donc l’âgisme), bien qu’elle n’ait pas été analysée dans ces études. Dès lors, le lien entre la vision de l’âge et les recommandations cliniques constitue l’objectif de notre étude. Méthodologie (1500 caractères) : Nous avons interrogé 76 infirmiers (-ères) travaillant en oncologie et étant en contact régulier avec des patients âgés (67 femmes, 9 hommes, M âge = 33,88 ans). Il leur a été proposé de donner leur avis sur quatre fiches cliniques et de compléter deux questionnaires. La première fiche clinique concernait une nouvelle immunothérapie contre le cancer du poumon. A sa lecture, il était demandé aux infirmiers de noter, sur une échelle de 1 à 7, dans quelle mesure ils recommanderaient à leur patient (40 vs 70 ans) de suivre ce traitement expérimental. Les 3 autres fiches cliniques concernaient une patiente en bon état général atteinte d’un cancer du sein et ayant été traité par mastectomie. Les paramètres cliniques étaient strictement équivalents dans les 3 cas : seul l’âge de la patiente changeait (35, 55 ou 75 ans). Pour chaque fiche, les infirmiers devaient noter sur une échelle de 1 à 7 à quel point ils encourageraient le patient à suivre un traitement chimiothérapeutique et à demander une reconstruction mammaire Les infirmiers étaient également interrogés sur leur vision de l’âge de manière explicite via un questionnaire (FSA-R ; Boudjemad & Gana, 2009) et de manière implicite sur base des 5 premiers mots qui leur venaient à l’esprit lorsqu’ils pensaient à une personne âgée (informations récoltées au sein du questionnaire anamnestique global). Résultats (1500 caractères): Concernant le traitement expérimental, sa recommandation est moins fréquente pour une personne de 70 ans comparativement à une personne de 40 ans (p<.001). Cette moindre recommandation est associée à une tendance à citer plus de mots négatifs relatifs à la personne âgée (p =.09). Aucun résultat n’a été trouvé en lien avec la mesure explicite de l’âgisme. De plus, le personnel soignant recommande moins fréquemment une chimiothérapie pour une personne de 75 ans comparativement aux personnes de 55 et 35 ans (p<.001). Ce résultat ne semble pas influencer par la vision de l’âge du personnel soignant. Au niveau de la reconstruction mammaire, une différence est visible dès 55 ans : la reconstruction mammaire est moins recommandée pour une personne de cet âge par rapport à une personne de 35 ans (p=.02). Elle l’est encore moins pour une personne de 75 ans comparativement à une personne de 55 ans (p<.001). De plus, la différence de recommandation entre une personne de 75 et 35 ans semble être influencée par la vision de l’âge du personnel (mesurée par le test du FSA-R) : une vision plus négative est associée à un encouragement moins fréquent pour une personne de 75 ans comparativement à une personne de 35 ans (p = .01). Nous n’avons pas trouvé de lien avec la mesure implicite de l’âgisme. Conclusion (800 caractères): Nos données confirment que les recommandations cliniques telles qu’une reconstruction mammaire ou une chimiothérapie sont moins fréquente chez les personnes âgées que chez les jeunes. De plus, nos résultats montrent qu’une vision négative de l’âge est associée à une moindre propension à proposer une reconstruction mammaire. A l’inverse, la vision de l’âge ne semble pas influencer l’encouragement pour un traitement chimiothérapeutique : des attitudes âgistes sont observées même quand le personnel a une vision positive de l’âge. Ces résultats doivent cependant être confirmés par d’autres études notamment menées auprès d’autres professionnels en oncologie gériatrique. Lors de celles-ci, l’ajout d’autres mesures implicites de l’âgisme nous paraitrait intéressant.

[more ▼]This presentation highlights the last reflections of the author on NWM in Belgium. It focuses on the new governance practices in Belgian nuclear waste management (NWM) from its ‘participatory turn’ in the late 1990s. Rather than praising (or rejecting) participation versus expert analysis, we make use of a theoretical and analytical framework in which the important dynamics for the analysis are ‘opening up’ and ‘closing down’ technological appraisals and commitments. Even though NWM agencies often plea for an integrative approach between experts analysis and participation, in practice this reveals itself rather complicated as both exercises are often kept separate. We address this separation and its consequences and we find that societal concerns remain subsumed in the technical options which have long been favoured by the Belgian agency. This taming of uncertainty may come at a high price, if it systematically reduces the scope of alternative options for governance intervention or if societal consultations ultimately appear like an instrument of legitimation of already-taken decisions.

[more ▼]The University of Liège Library's books collection is composed of some 2,000,000 print volumes, of which only 60% are catalogued. Most of the uncatalogued books have been published before 1970 and cataloguing these according usual standards and norms would certainly take decades. To decrease the cost of treatments and increase the number of catalogued volumes, the Library developed a light PHP/MySQL application, Scriptorium, that enables non-catalogers (mostly students) to quickly encode the books (ca 3 min. per item) by providing the most essential information. References are then daily exported in MarcXML to the ILS. Scriptorium has been developed to permit to easily create new independent instances for different parallel retro-cataloguing projects and also to be used by other libraries.

In the vulnerability assessments, many ... [more ▼]A general physically based method is presented to assess vulnerability of groundwater to external pressures with respect to quality and/or quantity issues. In the vulnerability assessments, many scientific authors agree nowadays that ‘physically based’ methods must be preferred to traditional approaches based on empirical overlay and index methods where physical attributes are often mixed with implicitly embedded conventional priorities. Results from one or another of these last methods can consequently be very dissimilar for a given case study and decision makers are losing confidence in these tools. A methodology is proposed to reframe the groundwater vulnerability assessment in a Pressure-State-Impact causal chain that is familiar to decision makers. The DPSIR framework, for describing interactions between society and the environment, defines a chain of Drivers that exert Pressures on the State of a given resource, such as water, which then generates an Impact that will require an appropriate Response (Kristensen, 2004). The concept of groundwater vulnerability assessment considered here is based on the calculation of sensitivity coefficients for a user-defined groundwater state for which several physically-based indicators are proposed. These sensitivity coefficients reflect the easiness with which the groundwater state transmits pressures into impacts. They are grouped into a vulnerability matrix of pressures and impacts that quantify vulnerability for every combination of causal links identified in the DPSIR chain. For that reason, the sensitivity coefficients are converted to vulnerability, using the concept of ‘falling below a given threshold’, which is commonly used in socioeconomic sciences (Luers et al. 2003). Outside the careful selection of the sensitivity analysis method that can significantly influence the computational effort (Beaujean et al., 2013), emphasis will be given to the illustration of the general methodology on a simple case (of an alluvial aquifer with concerns related to water supply) demonstrating the potential use of this general and physically based vulnerability assessment method. While the methodology is general, the choice of causal chains has to be made prior to the calculation. The vulnerability is also related to a damaged state and is related to the ‘distance’ between the current state and a given threshold. This choice is arbitrary such that the vulnerability is sensitive to the choice of the threshold. The framework is general and, when applied to water, can include states that are not limited to quality such as, for example, water quantity and availability.

[more ▼]Climate change will bring new pressure on surface and groundwater resources (e.g. Allen et al., 2004; Goderniaux et al., 2009; Van Roosmalen et al., 2009) in many parts of the world. Additional work is required to help water managers to plan for future changes. For example, most of studies provide projections for a stationary climate representative of the end of the century, although information is demanded for the near-future. A sophisticated transient weather generator (WG) in combination with an integrated surface-subsurface hydrological model (HydroGeoSphere) are used for producing a stochastic generation of large numbers of equiprobable climatic time series, representing transient climate change, and assess impacts on groundwater resources in a probabilistic way. This new methodology is applied for the unconfined chalky aquifer of Hesbaye (Geer basin in Belgium). The following uncertainty sources are studied : (1) the uncertainty linked to the calibration of the hydrological model, using 'UCODE_2005' (Poeter et al., 2005); (2) the uncertainty linked to the global and regional climatic models (GCMs and RCMs), by using a multi-model ensemble; (3) the uncertainty linked to the natural variability of the weather, by using stochastic climate change scenarios. 30 equiprobable climate change scenarios from 2010 to 2085 have been generated for each of 6 different RCMs. Results show that although the 95% confidence intervals calculated around projected groundwater levels remain large, the climate change signal becomes stronger than that of natural climate variability by 2085. Additionally, the WG ability to simulate transient climate change enabled the assessment of the likely timescale and associated uncertainty of a specific impact. This methodology constitutes a real improvement in the field of groundwater projections under climate change conditions as it enables water managers to analyse risks and take decisions with full knowledge of projected impact and their degree of confidence.

[more ▼]Surface waves and magnetic reconnection are two key processes taking place at the planetary magnetopause. They allow the coupling, through energy (and particle) transfer, of the interplanetary medium and the magnetosphere. The relative importance of large scale Dungey reconnection and viscous interaction (including small-scale intermittent reconnection associated with Kelvin-Helmholtz vortices) are expected to be different at Jupiter compared to the Earth’s case. Such differences would be due to the combination of a) a weaker solar wind pressure and Alfvén velocity as the distance to the Sun increases, b) a high-β plasma sheet, originating from Io’s outgassing, which inflates the Jovian magnetosphere, c) the rapid rotation of the planet relative to its size (e.g. Desroche et al. 2012). Here we analyse the signatures of wave activity and reconnection on the magnetopause of Jupiter, based on magnetic field and energetic particle measurements from the successive spacecraft that explored the Jovian system. Up to now, 7 spacecraft equipped with a magnetometer have crossed the Jovian magnetopause: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2, Ulysses, Galileo and Cassini. We make use of several normal direction finding techniques, such as the Minimum Variance Analysis, in order to identify waves and Kelvin-Helmholtz vortices. As far as the reconnection is concerned, small scale signatures of flux-tube events (FTEs) had been identified by Walker and Russell (1985), based on a limited data-set from the Pioneers’ and Voyagers’ fly-bys. Here we will extend this search to the extensive dataset from all the missions that explored Jupiter’s system.

[more ▼]From January to April 2014, two observing campaigns by multi-wavelength remote sensing from X-ray to radio were performed to uncover energy transport process in Jupiter’s plasma environment using space telescopes and ground-based facilities. These campaigns were triggered by the new Hisaki spacecraft launched in September 2013, which is an extremely ultraviolet (EUV) space telescope of JAXA designed specifically for planetary observations. In the first campaign in January, Hubble Space Telescope made imaging of far ultraviolet (FUV) aurora with a high special resolution (0.08”) through two weeks while Hisaki continuously monitored aurora and plasma torus emissions in EUV wavelength with a high temporal resolution (1 min<). We discovered new magnetospheric activities from the campaign data: e.g., internally-driven type auroral brightening associated with hot plasma injection, and plasma and electromagnetic filed modulations in the inner magnetosphere externally driven by the solar wind modulation. The second campaign in April was performed by Chandra X-ray Observatory, XMM newton, and Suzaku satellite simultaneously with Hisaki. Relativistic auroral accelerations in the polar region and hot plasma in the inner magnetosphere were captured by the X-ray space telescopes simultaneously with EUV monitoring of aurora and plasma torus. In this presentation, we show remarkable scientific results obtained these campaigns mainly focusing on Jupiter’s aurora.

[more ▼]Background: The incidence of incisional hernias (IH) after open abdominal aortic aneurysm (AAA) repair is high. Prophylactic mesh augmentation (PMA) during laparotomy closure has been proposed in high-risk patients. Methods: A multicenter prospective randomized controlled study was conducted on patients undergoing elective repair of AAA through midline laparotomy (Clinical.Trials.gov: NCT00757133). In the study group a retro-muscular PMA was performed with a large-pore polypropylene mesh (Ultrapro™, width 7.5 cm). The primary endpoint was the incidence of IH at 24 months. Results: Between February 2009 and January 2013, 120 patients were recruited at 8 Belgian centers. Patients' characteristics at baseline were similar between the groups. Operative and postoperative characteristics showed no difference in morbidity or mortality. A highly significant reduction of IH incidence was found after PMA compared to conventional closure, respectively 0% (CI: 0 % - 5.5%) versus 27.6% (CI: 16.7% - 40.9%) (P<0.0001; Fisher's exact test). The estimated "freedom of IH" curves (Kaplan-Meier estimate) were significantly different across study arms (X2=18.93, P<0.0001; Mantel-Cox test). No adverse effects were observed, apart from an increased mean (SD) time to close the abdominal wall for PMA: 46.2 min (18.6) versus 29.6 min (18.5) (P<0.001; Mann-Whitney U test). Conclusion: Prophylactic retro-muscular mesh augmentation of a midline laparotomy in AAA patients is safe and effectively prevents the development of IH, with an extra time investment of 17 minutes.

[more ▼]We present images of Jupiter’s northern UV aurorae taken by the Hubble Space Telescope as part of a large observing campaign in January 2014. The high time resolution observations allow the dynamics of the different components of the aurorae to be observed. Particular features of interest are large regions of diffuse emission, which occurred equatorward of the main oval, enveloping the auroral footprint of Ganymede. These diffuse, low latitude emissions are caused by the injection of hot plasma from the outer magnetosphere, a process which has previously been related to interchange between the flux tubes from the outer magnetosphere and outward-moving flux tubes loaded with iogenic plasma. Over the two-week observing interval the auroral signatures of two large injection events were observed, while the main oval generally decreased in intensity. We suggest that the overall dimming of the main oval results from the weakening of the corotation-enforcement currents that drive the main emission, following the replacement of the radially-stretched, mass-loaded flux tubes by more dipolar flux tubes containing rarefied hot plasma.

[more ▼]Bibliometric indicators might be inappropriate tools to evaluate public funded research whose aim is to deal with the socio-economic challenges endured by a nation. By the means of a bibliometric analysis (Web of Science, period 1981 – 2011 for Belgium) combined with qualitative material, it has been argued that the kind of research that is more likely to address societal issues (based on its language, its type of collaboration and its type of research) is the one with the least scientific impact as measured by bibliometric measurements. The outcome of this study helped us realise that there exists a paradox of incentives for academic researchers due to an inadequacy between the production of knowledge that address societal issues and its evaluation: (1) traditional evaluation methods do not produce enough incentives to address societal challenges and that (2) scientists are intensifying their effort to produce valuable results for their evaluation.

[more ▼]Theoretical background: Cannabis is the most commonly used illicit drug among teenagers. Initiation is influenced by environmental factors and personal characteristics, events or experiences. An early initiation increases the risks of problems related to cannabis use (e.g. negative psychosocial effects, delinquent behaviors, mental disorders). Prevent initiation, through the identification of risk/protective factors and their interaction, seems crucial in terms of public health. Research question and significance: This study aimed to examine the progression of use, to identify protective and risk factors of cannabis initiation (including peers, alcohol, expectancies and internalizing factors) and to specifically focus on the influence of social anxiety and its moderators/mediators. Methods: A questionnaire was administered twice to 877 teenagers (49.94% female, M=15.61) with one year interval. Sex, age, demographic variables, peer cannabis use, cannabis-related variables (lifetime, frequency, problems and expectancies), alcohol use, social anxiety, trait-anxiety and depression were assessed through validated scales. Logistic regressions, mediation and moderation analyzes were performed. Results: During the follow-up period, 12.89% of the young participants initiated cannabis use. Several factors significantly predict initiation: alcohol use, peer users, perceptual enhancement and craving effect expectancies. Others factors significantly protect from initiation: negative behavioral effect expectancies and social anxiety. Gender, age, relaxation/social facilitation and cognitive impairment effect expectancies, trait-anxiety and depression do not significantly influence cannabis use initiation. In moderated mediation model, after controlling for relevant variables, social anxiety protected from initiation trough the mediating role of perceptual enhancement and craving effect expectancies. The number of peer users and alcohol use do not moderate this mediation. Negative behavioral effect expectancies do not significantly mediate the relation between social anxiety and cannabis initiation. Interpretation of findings: Through low positive expectancies, adolescents with social anxiety symptoms are less likely to initiate cannabis use than the others, whatever the number of peer users and the alcohol use. Findings are discussed in terms of risk and protective characteristics of relevant factors, in an overall and evolutionary approach including internalizing factors. Results support the identification of internalizing profile of adolescents concerned by prevention or treatment and the importance of social anxiety and expectancies in intervention.

[more ▼]designate any kind of advanced ore characterisation prior to mineral processing operations while in fact it should clearly refer to a multidisciplinary integration of geological, mining, metallurgical, environmental and economic information into a single orebody model. In order to instil the best available geometallurgical practices in the professional world, it seems essential to break the traditional cleavages among disciplines and educate a new generation of engineers. The Erasmus Mundus EMerald “Master in Georesources Engineering” program initiated by four European universities under the coordination of University of Liege, has been designed to exactly tackle this challenge. It is not surprising that this program has been set up by universities having a long tradition in mixing a double perspective of geology and engineering (Nancy; Lulea; Liege and Freiberg). Geometallurgy requires both an excellent understanding of the natural variability and complexity of an ore and a comprehensive overview of the techniques available to extract and concentrate any valuable material. The course program has been designed to achieve a right balance between knowledge of mineral resources (geology, resource characterisation, reserve estimation, modelling) and processing (comminution, preconcentration, leaching, waste disposal,...). It also includes a broader view on life cycle analysis and urban mining. A series of professional seminars, suggested by an industrial advisory board, shed light on strategic issues, economic and environmental challenges, corporate social responsibilities, etc. Mobility and multicultural experience is an added-value of the Erasmus Mundus experience which definitely contributes to breeding engineers for tomorrow.

This low level of performance is not really unexpected as it was already observed at grade 7 and grade 8 in TIMSS 1995 (Harmon, Smith & Martin, 1997). In mathematics and in reading, the average performance of the 15 year-olds do not significantly differ from the OECD mean. Can these differences in performance in comparison with the OECD means be partly attributed to the emphasis and importance of the respective intended and implemented curricula? Does the relative importance of science teaching differ between primary and secondary education? In this investigation, we make the assumptions that the problem already exists in primary education and persists in secondary education. Therefore, we will focus on primary education. Data will be mainly collected on opportunities to learn (OTL) for science education and on professional knowledge and teaching practices More precisely, these study intents to question teachers at grade 3 and grade 4 about their beliefs and practices in science. Do the primary teachers feel confident and comfortable with science knowledge and science teaching? What’s the effective learning time of our pupils in science? Can we identify patterns of teachers that current international research has shown to have a significant role in science education of pupils?

[more ▼]Cerebral palsy describes a group of disorders of the development of movement and posture, causing activity limitation, that are attributed to nonprogressive disturbances that occurred in the developing fetal or infant brain. The vulnerability of different brain structures and types of disability associated with CP are influenced by the gestational age at which brain development is altered. Understanding the pathophysiology of CP is crucial for the development of neuroprotective strategies. In the first trimester of gestation, genetic disorders, infectious and toxic diseases explain the vast majority of lesions. In the preterm newborn, neuroinflammation and anoxo-ischemia induce activation of the microglia and a maturational blockade of oligodendrocytes disrupting the developmental program of white matter. In term infants, hypoxic-ischemic encephalopathy is the consequence of the excitotoxic cascade leading to cortical and/or basal ganglia lesions. Clinical disabilities are the consequence of these lesions modulated by cerebral plasticity process.

[more ▼]Clam farming in coastal provinces of Vietnam has notably developed since the last decade. It generated high income, improve socio-economic development for many local communities. However, many clam raising farms are facing difficulties of farm management, disease control, markets and systems of quality control. This research aims to study about the real situation of cost monitoring in the clam raising farms in the Northern area of Vietnam and suggest some recommendation for apply a suitable model for cost monitoring to promote the value added for farmers. The paper based on the semi-structure, standard questionnaires and PRA method to collect data from 89 clam raising farms in two coastal provinces (Nam Dinh and Thai Binh) in the Northern area of Vietnam in 2014. The findings show that clam raising provides farmers a chance of getting high income parallel with high risk. There were 32.15% surveyed farms got profit, 32.14% of them met the breakeven and 35.71% was lost. The study finds out four key factors affecting farms’ economic performance and efficiency. The first is capacity of farm cost control as the cost for clam raising was very high at 8,142 to 9,190 USD per ha. The second is the farmers’ experience, skill, technique and ability of risk control. The third is low, unstable market price and unsuitable market channel with the dominant of the traders. Final factors is the area and location of clam raising. Despite of these difficulties, 55.14% surveyed farms still want to expand their production, 25% of them will continue, and only 17.86% will stop or change to other activities. In order to promote the value added for clam raising farmers, cost control should be paid more attention, improvement of the farmers’ capacity is necessary, and market should be regarded.

[more ▼]geometallurgy will become the central pivot of a successful mining operation. Recently, Europe has awakened from a long period of lethargy in the raw materials sector. A series of important initiatives inspired by the European Innovation Partnership (EIP) have paved the way for more intense cooperation between industry, research centres and universities. Among these, the establishment of a Knowledge Innovation Community (KIC) in 2015 will definitely boost innovation and education in the sector. Interestingly, EIP addresses the whole value chain and considers mining, recycling and substitution as essential pillars of the raw materials policy. This vision strengthens the role of geometallurgy but also brings up the need for a close dialogue between mineralogists, metallurgists and product designers. Microelectronics and nanotechnologies are ubiquitous in our technologies and have greatly improved their functionality, but they have also made recycling and efficient recovery of metals a tough technical challenge. Our urban mines formed by the accumulation of end-of-life products should be scrutinized from now on using an ecometallurgical approach whereby important questions should be addressed such as: 1. Metal concentrations: Is the metal grade high enough to pay for recycling? Does the manufacturer help to maintain grades above a technological cut-off? 2. Metal speciation: Under which form (alloy, salt, organic compound,…) is the metal present? Is there a processing technology available to separate these species? 3. Metal paragenesis: What are the metal assemblages found in the product? Will it be feasible to separate those metals and at what costs? Are there penalty or contaminating elements associated? 4. Textural assemblage: How will the product behave during dismantling? Is it realistic to liberate a given component? What comminution strategy will be needed to achieve phase liberation? 5. Reserve estimation: What are the tonnages expected for this kind of product? Can selective collection be organised? 6. Homogeneity: What will the next generation of products look like? Should one expect strong differences in concentration, speciation, paragenesis, etc.? Will this kind of product be blended with others during collection? How will this impact on downstream recycling? Ecometallurgy, as introduced here, is essentially about establishing a dialogue with product designers and material scientists to make sure that, once unearthed, metals will remain easily and sustainably available for the future generations. Geologists and mineralogists, even though generally kept away from the synthetic materials, could greatly contribute to this progress by bringing their expertise in dealing with complex and variable orebodies of the future.

[more ▼]Quantitative mineralogy of fine particles in slurry from multispectral imaging Sophie Leroy, Godefroid Dislaire, Pierre Barnabé and Eric Pirard Mineral processing especially in its final stages relies heavily on the differential behavior of particles in pulps. In order to monitor hydrocyclones and flotation cells in almost real time, it is important to develop at line particle characterization providing information on particle distribution but also mineralogy. A sampling device has been elaborated based on a flow cell with variable wall spacing linked to a high pressure peristaltic pump. This setup allows for dispersion and dilution of the mineral slurry into the cell. Depending on the ore or gangue minerals to be controlled, particles can be imaged either in diffuse reflectance or in transmittance mode. A simple multispectral imaging module has been designed to acquire images at eight different wavelengths. The design is based on a series of dichroic filters thereby avoiding any moving part and enabling a very fast acquisition of multispectral images. Imaging artifacts due, among others, to specular reflectance from the glass window are minimized. Multispectral classification is used to outline particles appearing in the field of view and to qualify their main mineral component. In particular, areas reflecting a meaningful and discriminative spectrum are identified and compared to a multispectral database. The database is continuously enriched through testing of pure mineral particles under similar pulp conditions (dilution, grain size,…). Results of final classification are compared to the modal analysis obtained from polished blocks and conventional reflected light microscopy. The technology developed in this work sets the basis for at line monitoring of ore slurries with reasonably simple mineralogy. Extension of the spectral range is being considered for future developments.

[more ▼]Purpose An abundant literature indicates that Organizational Citizenship Behaviours (OCBs) positively influence a number of important organizational outcomes. Furthermore, research is needed on the topic of assessing and selecting applicants who have a propensity to exhibit OCB (Organ & al., 2010). Some of these behaviours are truly important to enable organization to adapt and “to make constructive changes in the work and task environment” (Choi, 2007, p.468). Examples include Voice, a challenging dimension of OCB (Dominguez & al., 2013), and Sportsmanship, that facilitate the change by reducing the diversion of resources in trivial matters (Organ & al., 2006). This exploratory study provides empirical evidence about using Situational Judgment Tests (SJTs) for identifying applicants who have a propensity to exhibit change oriented OCB. Method Two SJTs were developed to comply with OCBs assessment. The OCBs framework includes behaviours relating to organizational adaptation (sportsmanship) and change (voice). OCBs were concurrently collected using self-reported measurement scales. Data were collected from 220 white collars and 139 university students through an online survey. Results Significant correlations were found between the SJT scores and overall OCB ratings. More specifics findings provided substantial evidence for the concurrent validity of the SJTs to measure change-oriented sub-dimensions of OCBs. Conclusions Researches on techniques to predict OCBs are scarce and this study is the first to address the development and validation of a SJT for the assessment of affiliative and challenging dimensions of OCBs.

[more ▼]Observations have been made with the Hubble Space Telescope in the timetag mode using the STIS long slit. During the 40 min of the observations, the slit spatially scanned the polar regions to build spectral maps of the jovian aurora. The emission is composed of the HI Lyman-alpha line and the H2 Lyman and Werner bands. The shorter wavelengths are partly absorbed by the methane layer overlying the bulk of the auroral emission. Since the CH4 absorption cross section drastically drops above 140 nm, the longer wavelengths are not absorbed and the intensity directly reflects the precipitated energy flux carried by the electrons. Maps of the intensity ratio of the two spectral regions will be presented, together with the associated auroral electron energy. These values will be compared with those expected from current magnetosphere-ionosphere model. They will provide input into 3-D modeling of the auroral heat source into the high-latitude Jovian upper atmosphere.

[more ▼]Elicitors are plant immunity-triggering compounds which are currently considered as one of the most promising tools in agriculture for the induction of plant resistance to various diseases (Mejía-Teniente et al., 2010). By contributing to both economic and environmental performances of agroecosystems, they can help reducing the use of chemical inputs. Although some elicitor products are already available on the market, it appears that a variable efficiency in the field, along with an uneasy integration in the current legislation and agricultural strategies, make these tools difficult to use (Walters, Ratsep, & Havis, 2013). Besides these limitations, few elicitor treatments have yet been efficiently and specifically designed to protect crop plants such as wheat, which is grown and consumed worldwide, against major diseases threatening both their yield and quality. There is a strong need to better understand the mechanisms of induced resistance in plants and develop elicitor use in agriculture. A phD research is currently led in Gembloux Agro Bio-Tech to develop a method based on eliciting agents, tested in greenhouse and field conditions, to protect winter wheat against major diseases, namely Septoria tritici, Fusarium graminearum and Fusarium culmorum. This project focuses on the screening of a large number of elicitors from different origins and structures. In 2014, we focused the first screening experiments on the protection of wheat against Septoria tritici Blotch (STB). Two winter wheat genotypes were tested: susceptible ‘Avatar’ and semi-resistant ‘Sy Epson’. Plants at 3-leaf stage were first sprayed till runoff with different concentrations of elicitors, and then inoculated 5 days later with a Septoria tritici spore suspension (106 spores mL-1) using a hand sprayer. Control plants were treated, prior to disease inoculation, with sterile water (negative control) or with BION® (ASM, Syngenta Europe; positive control). The disease severity and incidence were scored every 2 days for 28 days post-inoculation (d.p.i) by measuring the percentage of area covered with lesions and bearing pycnidia on the third leaf. The first results of these tests should enable a first discrimination of elicitors considering their dose-efficiency to reduce disease severity. After further screening of all the elicitors in hand, a determination of the elicitation pathways of the most efficient molecules tested will be undertaken. We intend to study the influence of various factors (i.e Temperature, relative humidity, plant development stage) on the elicitation potential and develop a formulation to be finally tested under field conditions.

[more ▼]In modern ironmaking, granulation is the first step of the sintering process. It is typically carried out in continuous drum granulators using water as a binder, and involves multiple components besides iron ores, such as return fines and other recycled materials (dusts, mill scale, sludges), solid fuel (coke breeze or anthracite) and fluxes (limestone, lime, olivine, dunite or dolomite) (Ball, 1973). As it is necessary to maintain a consistent quality of the granules (size distribution, porosity, strength, etc.) despite of the varying iron ore origins, the question arises as to how the properties of the iron ore particles (size and shape) influence the granulation process. The granulation process is partly influenced by the characteristic of the feed and partly by the action of cohesive force inside the drum granulator (Newitt et al. 1958). The objective of this paper is to study the effect of raw material properties on the kinetics of iron ore granulation considering in particular the mechanisms ruling wet granulation for two iron ores and to know the factors which determine the texture, shape, porosity and mechanical strength of the granules.

Several properties of the auroral emissions are analyzed. The mapped radial position and System III longitude of the observed auroral features are in good agreement with those of the injections observed in the equatorial plane by Galileo. Finally, we discuss the processes causing auroral signatures of injections. This comparative study demonstrates that the structures under study are most probably related to magnetospheric injections and sheds light to the mechanism involved in the magnetosphere-ionosphere dynamics.

[more ▼]Both in Europe and in the United States, scientific research and science, technology and innovation (STI) policies have undergone profound changes for about thirty years. These transitions are often framed along dichotomous lines : an ‘old regime’ characterized by strong public funding, independent academia and a linear conception of innovation has supposedly been replaced by a ‘new regime’ in which research and innovation are conceived in systemic terms, regarding their economic and societal relevance (Rip 2000). My proposal states that this conceptualization is of little use when it comes to studying the evolution of STI policies at the regional level. In this paper, I investigate how global master narratives like the “Knowledge-based Economy”, the “Grand societal Challenges”, “Science, the endless Frontier”, “Responsible Research and Innovation”, etc. are locally articulated, and thereby become grounded in regional STI policymaking, research, and innovation. These narratives, as explanatory resources and mobilizing resources, provide stakeholders with different visions; they are related to power relations between groups and individuals, to institutional settings and to policy trajectories. In my contribution, I study the four narratives in context; i.e. in different situated discourses of STI stakeholders. I consider multiple issues: who is telling what, to whom, why, when, where, and in which form. Instead of dichotomizing, investigating the evolutions of STI policies with a narrative framework provides an enriched description for complex local situations, towards a more political reading of the transitions.

[more ▼]Imaging and understanding of iron ore granulation using X-ray microtomography. Evrard M., Contreras R., Pirard E. Most iron ores cannot be directly fed into blast furnaces because their particle size distribution will negatively impact the blast furnace permeability and hence the overall efficiency of the ore reduction process. The finest fraction (typ. < 6.3 mm) has to undergo a sintering process, wherein a mixture of iron ore, coke and flux (limestone, olivine,…) is heated, partially molten and transformed into pieces of sintered material with adequate size, porosity and strength characteristics to be fed into the blast furnace. The preparation of an adequate mixture involves a granulation process which is the subject of this study. Sintering and hence granulation of iron ores, is particularly important in Europe where iron ores show a downward trend in quality (finer particles, broader size range, lower grades with higher variability). In addition an increasing fraction of non-sintered material (return fines) is being added to the mix to optimize the resource efficiency while maintaining sinter quality. For most practitioners, microgranules (or micropellets) are considered as being composed of a nucleus (a particle in the range of 1 to 2 mm) surrounded by layers of the finest ore particles (typically the < 250 µm fraction). A series of experiments and 3D imaging tests have been performed in this study to better understand the granulation mechanisms. Microgranules are formed by mixing iron ore with water in a small rotating drum. Several parameters can be tuned during the granulation process: size and proportion of nucleating particles, size and proportion of fines, water addition, rotating speed, total duration,… Simple experiments using a single ore type (dominantly goethitic or hematitic) and water additions have been carried out systematically to better understand the kinetics of granulation. X-ray microtomography and subsequent 3D image analysis is used to identify and quantify the number of nuclei (when present), to measure the porosity and identify layering or cracks in the microgranule. Compared to previous studies on iron ore pellets (Farber et al. 2002; Shatokha et al. 2009; Shatokha et al. 2010), this work focuses on imaging prior to sintering. It also uses higher resolution micro-CT and definitely brings a better insight into granulation as compared to data from 2D imaging of polished blocks: less artefacts in apparent porosity due to sample preparation; good discrimination among components of the granule; clear identification of the nuclei; etc. This work is part of a larger European project (IMSIMI - Improved Sintering Mix) aiming at an optimal use of challenging input materials through carefully monitored preparation phases (mixing, granulation, etc.) and better understanding of their impact on the sintering process.

[more ▼]Bash Tapa is a circa 8 ha settlement, located 35 km South of Erbil, in Iraqi Kurdistan. Its exploration was began in September 2013 by a french archaeological mission, led by L. Marti (CNRS, Paris). The stratigraphical step trench excavated on the southern slope of the tell revealed six phases of occupation dating to the 3rd millennium BC, from the Ninevite 5 to the Early Dynastic III periods (ARCANE ETG 1 – 5). A first evaluation of the pottery material recovered in this operation revealed that there are different traditions represented at the site. In fact, while the material dated from the beginning of the Early Bronze Age is clearly related to the Northern tradition, the most recent 3rd millennium levels identified so far have provided us with pottery which could be connected to Central Mesopotamia, and more specifically to the Diyala region. This paper will give a first overview of 3rd millennium pottery from the two first campaigns of excavation at Bash Tapa, its links with the other regions of Near East and its significance for chronology.

[more ▼]The practice of “incident reporting” is commonly recognized as an effective mean to reduce the vulnerability of “at risk” socio-technical systems (e.g. nuclear plants, large industrial facilities or hospitals), as it allow the concerned community to learn from past incidents. Indeed, it is assumed that collective resilience will be upgraded via the use of institutionalized Incident Reporting System (IRS), enabling the organization to improve the quality of the actions and reactions in case of deviation from normality, or to prevent such deviation. Yet, inductive analysis of what happens with those IRS in practice are not numerous. In this paper, we address this gap and display the results of semi-structured interviews conducted in a nuclear facility. During those interviews, participants were also requested to produce a mind map of the IRS they are concerned with. As a result, we show that safety is a matter of solidarities that are situated in specific contexts. To that regard, incident reporting is a practice of decomposition and recomposition of trusts and thus of solidarities. Reporting incidents consists in putting solidarity on trial, as the collective safety was threatened. We show that such open trial is often avoided because questioning solidarities is not always desirable in order to allow the group to continue functioning. Overall, we argue that informal reporting behaviors can also contribute to upgrade collective resilience without putting solidarities on trial.

[more ▼]A feature of the organ of Corti’s supporting cells is the presence of an abundant cytoskeleton which is mainly composed of microtubules. These supporting cells have also been shown to contain a minor mammalian tubulin, the β5-tubulin [1], recently related as a biomarker for cancer outcome [2] and cell proliferation [3]. It was shown that a β-tubulin isoform can specified the microtubule architecture, such as the expression of the Moth β2 in the Drosophila testes imposed the 16 protofilaments (16pf) structure on the corresponding subset of Drosophila microtubules, which normally contain 13pf [4]. Moreover, supporting cell microtubules are formed by 15pf instead of the canonical 13, a unique fact among vertebrates [5]. Such a protofilament configuration has been observed in C. elegans’ neurons which are responsible for the mechanosensory sense of touch [6]. It was also shown that these 15pf microtubules were essential to the proper functioning of these mechanosensory neurons [6]. To determine the role of this particular tubulin in the auditory organ and its possible involvement in the formation of the unusual 15pf microtubules of supporting cells, we studied the spatiotemporal localization of β5-tubulin during development in rats from embryonic day 18 until P25 (25th postnatal day). We also analyzed the localization of β5-tubulin mRNA expression in the Corti’s organ. Then we examined the fine structure of microtubules at the electron microscope level. For these experiments, we used an early postnatal stage and a late postnatal stage. Our results showed that β5-tubulin, contrary to other β-tubulins, had a unique distribution in the cochlea. This β-tubulin appeared at a postnatal stage, before the opening of the Corti’s tunnel and being restricted to supporting cells, especially in pillar and Deiters cells,. The same localization of β5-tubulin mRNA was observed by in Situ Hybridization. Electron microscopy indicated further that Pillar and Deiters cells were composed by 15-protofilament microtubules at the late postnatal stage (P25). In conclusion, all these data strongly suggest that there is a relationship between the presence of β5-tubulin and 15-protofilament microtubules in the supporting cells of the auditory organ. Further studies are now needed to elucidate their role.
