We analyzed Sea Surface Temperature (SST) images in a region covering the Canary Islands and Madeira archipelagos, with the following objectives 1. The reconstruction of incomplete SST satellite images during the year 2009. 2. The determination of the main spatial and temporal patters in the region. SST images for 2009 are downloaded from the Medspiration project (http://www.medspiration.org). The images consist of combined measurements from several satellite systems. The images with less than 5% of valid pixels (e.g., clouds) were removed, so that out of the 365 initial images, 347 were kept. The method used in this work for the reconstruction of missing data is Data INterpolating Empirical Orthogonal Functions (DINEOF, Alvera-Azcárate et al., 2005). The results show that the first mode is largely dominant, with 87% of the variance explained, and represents the regional seasonal cycle. The second mode accounts for 9% of the variance and depicts a separation between coastal waters and open-ocean waters. The signal of the Cape Ghir upwelling filament is also present in the second mode. The reconstruction allows one to reproduce the characteristic mesoscale features of the region: the coastal upwelling, the island wakes (Gran Canaria, Madeira, ... ), the filament and the eddies in the lee of the main islands. A near-operational version of the reconstruction has been implemented and is available at http://gher-diva.phys.ulg.ac.be/DINEOF/dineof_allCAN.html [less ▲]

The aim of this lecture was to investigate the relation between scribal variation and language change in pre-Demotic Egyptian, focusing more specifically on “The best case scenario in the worst cultural environment”, i.e. the text community of Deir el-Medineh during the 20th Dynasty. The talk was methodologically oriented and several case-studies (related to the diaphasic and diachronic dimensions of variation) were presented in order to illustrate some principles and to suggest new ways of investigation in the description of Ancient Egyptian variation. Additionally, the possibility of a scribal network analysis of the written material found in Deir el-Medineh has been discussed. [less ▲]

Vu le rôle central que jouent les méthodes d’analyse dans l’ensemble des activités tant de l’industrie (bio)pharmaceutique, agro-alimentaire, chimique ou dans l’environnement, il est essentiel de les valider. Les critères de validation ne sont pas une finalité et il est nécessaire de rappeler l’objectif d’une méthode analytique et de sa validation afin de planifier adéquatement cette étape de validation. Par ailleurs, les approches de décision habituelles qui se basent seulement sur des estimateurs ponctuelles ne répondent pas à l’objectif de la validation. Une stratégie alternative pour décider de la validité des méthodes est proposée utilisant les intervalles de tolérance : "ß-expectation tolerance interval". [less ▲]

Massive binaries are important laboratories to investigate science topics related to stellar astrophysics. In particular, colliding winds in some massive binaries are known to produce strong X-ray emission, to accelerate particles, and to act as nucleation site for dust particles. Recent advances in the development of interferometric instruments coupled to long baseline facilities such as the VLTI allow us to observe astronomical targets at the milli-arcsecond scale. In the context of the study of colliding-wind binaries, this tool is likely to provide crucial information. I will briefly discuss ongoing observation campaigns aiming at using such interferometric facilities in the purpose to study the physics of colliding-wind binaries. [less ▲]

Dès le départ, le développement des nanotechnologies a été fortement soutenu par les pouvoirs publics et marqué par une vision particulière du futur de nos sociétés occidentales. C'est notamment pour cette raison que les sciences humaines et sociales (SHS) ont été conviées à participer à la réflexion autour des nanotechnologies, dans le cadre plus général (et concomitant) de l'innovation responsable. Que ce soit aux États-Unis ou en Europe, cette évolution s'est traduite par des tentatives de mobiliser les savoirs produits en SHS, et des les rendre "opérationnels" directement au coeur des processus d'innovation, de recherche et développement. Cette démarche d'"intégration", selon la dénomination consacrée, entend briser les barrières disciplinaires. Nous abordons l'un de ces programmes de recherche spécifique, auquel nous avons collaboré, et en tirons les conclusions provisoires ainsi que quelques conséquences. [less ▲]

A comparison between in situ and satellite sea surface temperature (SST) for the western Mediterranean Sea is presented. Several international databases are used to extract in situ data: World Ocean Database (WOD), MEDAR/Medatlas, Coriolis Data Center, International Council for the Exploration of the Sea (ICES) and International Comprehensive Ocean-Atmosphere Data Set (ICOADS). The in situ data are classified into different platforms or sensors (CTD, XBT, drifters, bottles, ships), in order to assess the average difference between these type of data and AVHRR (Advanced Very High Resolution Radiometer) SST satellite data. Attention is given also to the relative accuracy of each database, and advantages and shortcomings on the use of each database will be discussed. The error assessment will be used to merge in situ and satellite SST data using DINEOF (Data Interpolating Empirical Orthogonal Functions), an EOF-based technique. The impact of the sensor-specific errors on the quality of the final product will be assessed, and compared to the results obtained when a more general error estimate is used. [less ▲]

The farrier is an important actor on the equine locomotor apparatus. The objective of this communication is to show direct and indirect interests for the farrier to use some radiological informations in his work. Today, however the existence of some new sophisticated imaging technics, radiography is the first choice to appreciate an equine locomotor lesion. The direct interest of radiography, when it concerns the distal limb, is to guide to the conception of an adapted orthopeadic horseshoe. The indirect interest of radiography, when it concerns proximal regions like shoulder, back or pelvic, is to help in the understanding of the whole horse as the loading of the joints is closely connected (Noble et al. 2010).The Objective of this presentation is to propose the basis in radiography of the horse, to give some examples in the equine digit radiopathology and to explain how several radiographic informations could be used by the farrier in his work process.

The serious offenses against civilian populations perpetrated by governmental and non-governmental armed forces are illegal view to the internationally established norms. These acts need primary support of the perpetrators and groups involved. As regards armed forces, processes of obedience to authority can explain breaking of War Law. Concerning mass violations due to civilians, an adhesion process to ideology of destruction is needed. Contributions of Freud in the field of leadership, the inversion of moral values and social desirability to this new order, as well as emotional manipulation of people, are elements of explanation of collective and massive acting out. To prevent these mass crimes, a study of the component parts which support them could allow us to understand the mechanisms in play. [less ▲]

The electromagnetic perturbations caused by the interaction between the moons Io, Europa, and Ganymede and the Jovian magnetosphere propagate along magnetic field lines in the form of Alfvén waves and finally create auroral footprints in Jupiter’s polar ionosphere. Thanks to the high spatial and temporal resolution of the Hubble Space Telescope, the analysis of the footprints in the Far UV domain provides extremely valuable information on these interactions. In the case of the Io footprint, the analysis of the multiplicity of the auroral spots and of their relative motion resulted into a new understanding of the far field interaction, which involves trans-hemispheric electron beams. Consistent with the in-situ energetic electrons observations, this scenario has been later reinforced by theoretical models simulating the Alfvén wave’s propagation and the ways these waves accelerate electrons. Moreover, while the altitude and the vertical profile of the auroral emissions provide crucial information on the energy of the precipitating electrons, the measure of the shape of the different sub-structures of the satellite footprints provides important clues about the size of the interaction region. The evolution of the footprint brightness is also an essential parameter for understanding the energies involved in the interaction. Finally, the study of the satellite footprints can also be used for broader purposes than just the investigation of the satellite-magnetosphere interaction, such as building more accurate Jovian magnetic field models.

Sur base de la sensibilité du phytoplancton aux apports anthropiques de sels nutritifs, la DCE a retenu un indicateur « Phytoplancton » pour contribuer à caractériser l’état écologique des masses d’eau. Il est composé de trois indices : la biomasse, l’abondance et la composition. La biomasse et l’abondance sont caractérisées par des métriques qui sont déjà validées ou en cours de l’être au niveau européen. Cette étude cible la composition du phytoplancton et utilise la signature pigmentaire des communautés pour développer un nouvel indice de composition taxonomique (IC Medit). L’indice IC Medit est adapté aux spécificités des eaux côtières méditerranéennes et aux besoins de la DCE. Il 1) caractérise l’évolution naturelle de la distribution saisonnière de 2 grands ensembles phytoplanctonique-clés; 2) incorpore la variabilité interannuelle des communautés; 3) reflète l’évolution de la qualité des masses d’eau; 4) permet d’émettre des hypothèses sur le type de pressions qui modifient la composition phytoplanctonique.

The circulation in the Ligurian Sea is dominated by strong currents, namely the Western Corsican Current and the East Corsican Current, which jointly form the Northern Current. A high mesoscale activity, including meanders and eddy formation, is associated to those energetic currents. The non-linear instability processes and apparently chaotic behavior of this current system make this region a challenging testbed for data assimilation. High-frequency radar surface currents have been measured by the NATO Undersea Research Centre (NURC), La Spezia, Italy from two sites at the Italian Coast (Isola Palmaria and San Rossore). Each of those sites measures the radial currents relative to the position of the radar system. This WERA system captures well the general circulation and mesoscale flow features. The present study shows an application of the assimilation of those measurements in a nested model con- figuration of the Ligurian Sea. It is assumed that the error in the model surface currents comes primarily from uncertainties in the lateral boundary conditions and surface wind fields. The objective of this study is to reduce the uncertainty in these forcing fields by data assimilation. An ensemble of 100 perturbed lateral boundary conditions and surface wind fields is created to take the uncertainty into account. Using an ensemble-smoother technique described in Barth et al, 2010 (Ocean Science) and Barth et al, 2010 (Ocean Dynamics, in press), improved estimates of the wind forcing and boundary conditions are obtained. By rerunning the model with the updated forcing fields, it is verified that the analyzed model solution is closer to the observed HF radar currents. This technique is similar to 4D-Var, but since it is based on the ensemble covariance between forcing fields and observations, it does not require the formulation of an adjoint. [less ▲]

Belgium constitutes a good illustration of Mill’s statement about public opinion in divided societies: “the united public opinion…cannot exist [in a country which citizens] read and speak different languages” (1993: 391-7). However, according to Lijphart (2007), sociological and political divisions are not problematic. On the contrary, his seminal work on consociationalism promotes such separations among social groups through power-sharing and self-rule. Concerning its electoral system, Belgium represents a striking case of consociational design; whereas criticised by several due to its consequences on the Belgian political system. Indeed, it implies an ethnicisation of political life while it favours intra-groups’ claims escalation as well as it prevents inter-groups communication. In this respect, the proposal for a federal electoral constituency (FEC) in Belgium was put back on the agenda in 2007. First proposed in 1979, the proposal was quite fairly debated during the electoral campaign and government formation.This proposal offers deliberative perspectives to that question. Indeed, electoral studies do not tackle citizens’ perceptions, at least not directly, nor do they focus on reasons of citizens’ opinions. Yet, a specific deliberative methodology (scenario workshop) can explore this research path. Based on data collected during autumn 2009, we can offer tentative answers to crucial questions relating to citizens’ opinions about the FEC: what do they think? Do they feel involved and concerned by this debate? Do they agree or disagree with the electoral reform proposal? And, more importantly, why do they think so when invited to deliberate with other citizens, politicians and experts? [less ▲]

In mid-1920s British Mandate Palestine, the German-born Jewish architect and planner, Richard Kauffmann (1887-1958), prepared a town planning scheme for Afula and a ‘preliminary regional development scheme for the Haifa Bay’. The topical relevance of these two experiments stands in the original relations they attempted to establish with the physical environment and the ‘geographic stage’ at a national scale. The chosen location for the foundation of the new town of Afula as an ‘intermediate agro-city’ was the barycentre of the Jezreel Valley, ‘cradle of the agricultural Communities’ and ‘core of the Jewish State’ (Koestler, 1946). Haifa, instead, was to be implemented into a major port city aimed to compete with Beirut on the international scene as the new ‘gateway to the East’, enhancing its local natural resources and features. Both schemes gain further consistency when considered within the wider frame of Zionist settlement strategy in British Mandate Palestine, especially along the Jezreel Valley, where Kauffmann also planned many agricultural settlements. Together, Kauffmann's 1920s’ projects form an early pre-State regional planning scheme. If this first comprehensive expression of the Zionist Nation-Space naïvely neglected the presence of the Arab Other, it did not entail yet the later obsession of Zionist and Israeli planning with military-led territorial conquest. Instead, the dominant theme of this early Zionist vision of the future Nation’s geographical horizon was the building of a new collective identity grounded in agriculture and the reinterpretation of local geographic possibilities: the development of an ‘ancient-modern’ transcontinental route between the Mediterranean and the Middle East. Widely overshadowed by both the official dominant Israeli architectural history and by the emerging critique, this experiment could instead open up to an alternative narrative of Zionist modern architecture and planning and usefully question present-day architectural and planning practice’s 'lost of the centre'.

Most of the IPCC-AR4 Atmospheric Global Circulation Models (AGCM) predict an increase of the Antarctic Surface Mass Balance (SMB) during the 21st century that would mitigate global sea level rise. Present accumulation and predicted change are largest at the ice sheet margins because they are driven by snowfall, which mostly comes from warm, moist air arising over the land slopes. The coastal belt is also where complex processes of sublimation, melt and redistribution by the wind occur. Thus, high-resolution modelling (5 to 10 km) is necessary to adequately capture the effects of small-scale variations in topography on the atmospheric variables in this area, but limitations in computing resources prevent such resolution at the scale of Antarctica in full climate models. We present here a downscaling method leading to 10-km SMB resolution for century time-scales over Antarctica. We compute the effect of the fine topography on orographic precipitation and on boundary layer processes that lead to melt and sublimation. We show that the accumulation downscaled from ERA-Interim is in good agreement with field measurements for the last 40 years. We then display the SMB downscaled from LMDZ4 AGCM outputs (~60-km resolution), and show that the downscaling improves the agreement between present modelled and observed SMB. Finally, we present hi-resolution features of the Antarctic SMB evolution during the 21st century downscaled from LMDZ4 and discuss the effect of the resolution on the Antarctic SMB contribution to sea level change. The downscaling model is a powerful tool that will be applied to others climate models for a better assessment of future sea level rise. [less ▲]

Throughout human history, different authorities have prescribed what to eat and what foodstuffs to avoid. This paper looks at one particular authority that has gained considerable influence in the past two decades: nutrition science. Our aim is to render a subfield of nutrition science called ‘functional food science’ ethnographically analyzable, in order to add more precision to the common statement that the ‘findings’ of ‘scientists’ have become recognized by ‘the European Authorities’. Which actors are involved, what are the actors’ respective playing fields, and how are these fields related? The paper is divided in a descriptive part, and a discussion section. In the descriptive part, we propose a brief genealogy of functional food science and the construction of a new scientific gaze on food. The genealogy enables us to distinguish a series of actors, choices, and locally rooted practices in a story that is qualitatively different from accounts in terms of scientific universality. The discussion section at the end of this paper proposes further venues for anthropological research into the relations between science, health and power in a competitive economic and political order. These research questions problematize the meaning and substance of ‘innovation’. [less ▲]

Teachers and students suffer from the impact of noisy classrooms. This is due to poor sound isolation, traffic and noise generated by electronic data processors, HVAC (Heating, Ventilation and Air Conditioning) interference and reverberation levels. For teachers, this resulted in increased vocal loading and fatigue, frequently leading to vocal issues. Furthermore, poor acoustic conditions influence children language acquisition process, sometimes leading to impaired concentration, behavioural disorders, and attention deficit. The problem is more enhanced in children with hearing impairment (temporary or permanent) or with other disabilities. Lack of information and normative data on the aspects of building design and classroom acoustics have prompted this review, which comprises of sources originated from Canada, France and Belgium.

The purpose of this study is to evaluate the impact on voice of both duration and intensity level of 2 hours of continuous oral reading. Fifty normophonic women (mean age: 25.4 years) undergo two sessions of voice loading in which the required intensity level of voice varied: 60-65 dB(A) for the first session, and 70-75 dB(A) for the second session. The results of loading are assessed with regard to objective data and self-rating of voice obtained every 30 minutes during the oral reading tasks. Serial voice quality objective data is obtained by use of Multi-Dimensional Voice program (Average fundamental frequency (AvF0), Jitter percent (Jitt), Shimmer percent (Shim), Noise-to-Harmonic Ratio (NHR)). Serial measurements of maximum phonation time (MPT) and voice range are carried out by use of Kay Elemetrics Computerized Speech Lab. The following characteristics are also categorized by the use of a 100 mm visual analogue scale every 30 minutes of the oral reading tasks: voice quality, feeling of phonation effort, vocal fatigue, and laryngeal discomfort. Results indicate that AvF0, lowest frequency of voice range, softest output of phonation, feeling of phonation effort, vocal fatigue and laryngeal discomfort rise during prolonged oral reading. On the contrary, Shim and self-rating of voice quality decrease significantly with the passage of time during the voice loading. Jitt and NHR tend to decrease. MPT decreases after the first 30 minutes but increases afterwards. AvF0 and highest frequency of voice range are the only parameters influenced by the required intensity of oral reading task: these values are significantly higher in the 70-75 dB session compared to the 60-65 dB session.

Aureobasidium pullulans (souche Ach1-1) a montré une grande efficacité vis-à-vis de Penicillium expansum agent de la pourriture bleue des pommes en conservation. Le présent travail a été réalisé dans le cadre de l’analyse des mécanismes d’action qui sont les plus impliqués dans son activité antagoniste. Dans des essais in vivo sur pommes blessées, l’effet protecteur de la souche Ach1-1 vis-à-vis de P. expansum a été significativement affaibli par l’ajout dans les blessures de concentrations élevées en acides aminés. L’importance de la réduction étant dépendante de la concentration appliquée, a montré que la compétition pour les acides aminés joue un rôle important dans la suppression de P. expansum. Ce résultat a été appuyé par l’analyse biochimique de la cinétique de l’épuisement des acides aminés dans les blessures des pommes qui a dévoilé que ces composés et particulièrement la sérine, la glycine et l’acide glutamique sont mieux métabolisés par la souche antagoniste que par le pathogène. L’ajout en excès de ces trois acides aminés individuellement dans les blessures des pommes a fortement réduit l’efficacité de la souche Ach1-1 vis-à-vis de P. expansum. Ainsi, ces acides aminés semble être parmi les éléments les plus limitants dans le mécanisme de la compétition. Ces résultats indiquent que l’antagoniste A. pullulans souche Ach 1-1 exerce une activité fongistatique plus que fongicide vis-à-vis de P. expansum et agit par une compétition efficace pour les éléments nutritifs limitants des blessures des pommes et particulièrement les acides aminés sans affecter la viabilité du pathogène.

Malgré la richesse et la vision collective que peut amener une équipe pluridisciplinaire, la pratique de médecine générale reste le plus souvent centrée sur les soins en réponse à une demande du patient et relevant d’une dimension individuelle. Malgré une motivation importante, l’équipe du CSI de Tilleur a du constater que le manque de compétences internes et le manque chronique de temps des soignants limitaient fortement ses aspirations à faire évoluer le modèle de soins vers les objectifs de globalité de prise en charge et pour l’ensemble des patients. Il a été décidé d’internaliser les compétences jugées manquantes par l'engagement d'une personne non soignante, dont la fonction est de soutenir l’équipe pluridisciplinaire dans ses projets de soins, de santé communautaire et de promotion de la santé. L’apport méthodologique propre à la santé publique en fait le point d’ancrage entre la conception d’un projet et sa réalisation concrète dans la pratique quotidienne. Des modifications structurelles commencent à apparaître parmi les soignants et des exemples de prise en charge globale de certaines pathologies ou actions préventives sont observés. La promotion de la santé, tant au niveau individuel que collectif, trouve une nouvelle place au sein d’une équipe principalement dédiée aux soins. [less ▲]

Purpose -- The purpose of this paper is to gain a better understanding of the market timing skills displayed by hedge fund managers during the 2007-08 financial crisis. Design/methodology/approach -- The performance of a market timer can be measured through the Treynor and Mazuy (1966) model, provided the regression alpha is properly adjusted by using the cost of an option-based replicating portfolio, as shown by Hübner (2010). We adapt this approach to the case of multi-factor models with positive, negative or neutral betas. This new approach is applied on a sample of hedge funds whose managers are likely to exhibit market timing skills. We stick to funds that post weekly returns, and analyze three hedge funds strategies in particular: long-short equity, managed futures, and funds of hedge funds. We analyze a particular period during which the managers of these funds are likely to magnify their presumed skills, namely around the financial and banking crisis of 2008. Findings -- Some funds adopt a positive convexity as a response to the US market index, while others have a concave sensitivity to the returns of an emerging market index. Thus, we identify "positive", "mixed" and "negative" market timers. A number of signs indicate that only positive market timers manage to acquire options below their cost, and deliver economic significant performance, even in the midst of the financial crisis. Negative market timers, by contrast, behave as if they were forced to sell options without getting the associated premium. We interpret this behavior as a possible result of fire sales, leading them to liquidate positions under the pressure of redemption orders, and inducing negative performance adjusted for market timing. Research limitations/implications -- The adjustment for market timing opens up the way to numerous tests over longer periods, and in particular comparative studies of hedge fund returns using nonlinear risk factors versus exposures to quadratic returns. Originality/value -- The paper suggests that the convexity in returns that is generally associated with market timing can be attributed to three sources: timing skills, exposure to nonlinear risk factors, or liquidity pressures. We manage to identify the impact of the latter two effects in the context of hedge funds. [less ▲]

Background. Fetal liver disease is a rare antenatal disorder for which etiology is frequently unknown. Recently, congenital alloimmune hepatitis emerged as a major cause of antenatal liver disease. Its typical presentation can be as a severe neonatal liver failure with hepatic and extrahepatic iron overload, a clinical state called neonatal hemochromatosis. Methods. A pregnant woman was investigated for heterogeneous fetal hepatomegaly. Pregnancy was also complicated by fetal alloimmune thrombocytopenia. The newborn presented at birth with liver cirrhosis and mild liver dysfunction. Follow-up until 36 months showed progressive normalization of all liver parameters. All metabolic and infectious analyses were negative. Liver biopsy showed severe hepatitis with post-necrotic fibrosis and regenerative nodules. There was no iron overload. To search for immune injury, paraffine sections of the liver biopsy were stained with an antibody against the membrane attack complex (MAC, anti human c5b-9, Peter Whitington’s Lab, Children’s Memorial Hospital, Chicago, IL), the terminal complement cascade neoantigen occurring specifically in complement activation by the IgG-mediated classical pathway, and which is responsible for cell death. Results. Strong immunostaining against MAC-antigen was found in the liver of the patient, with 90% of target hepatocytes whereas in a control group of patients with other neonatal liver diseases, it was 10.8±12.5%. Because IgG in neonates originate only from the mother, it signs the alloimmune nature of the disease. Conclusion. For a long time, pathophysiology of neonatal hemochromatosis remained unsolved. Recently, it was elucidated as congenital alloimmune hepatitis. With this case, we expend the recognized clinical spectrum by showing that congenital alloimmune hepatitis can present as milder cases, without iron overload. It should be considered as a cause of unexplained neonatal liver disease, even in the absence of siderosis. Such diagnosis is of great importance regarding the necessity of immunotherapy in further pregnancies in order to avoid recurrence of alloimmune injury [less ▲]

The Treynor and Mazuy framework is a widely used return-based model of market timing, but existing corrections of the regression intercept can be manipulated through derivatives trading. We propose an adjustment based on Merton's option replication approach. The linear and quadratic coefficients of the regression are exploited to assess the cost of the replicating option that yields similar convexity for a passive portfolio. A similar reasoning applies for various timing patterns and in multi-factor models. Our empirical application shows that, unlike existing performance adjustment methods, the portfolio replication approach uncovers a positive link between the convexity and the performance of market timing funds.
