Global Monitoring for Food Security (GMFS) is a Global Monitoring for Environment and Security (GMES) Service Element (GSE) project, part of the European Space Agency (ESA) contribution to the European Union (EU) /ESA GMES Programme. GMFS aims to establish an operational service for crop monitoring in support of Food Security Monitoring to serve policy makers and operational users. The GMFS project started in March 2003 as part of Stage 1 of the ESA Earthwatch GMES services Element “Service Consolidation Actions”, and was continued in October 2005 as part of the Stage 2 of the ESA Earth watch GMES services Element – “Scaling Up Consolidated GMES Services”. In this document an overview is given of the work done throughout the previous six years. GMFS aimed at monitoring crop state /vegetation condition at continental and national scale. Low resolution Earth Observation (EO) data was used for monitoring purposes at continental scale, while at national scale products were based upon medium and high resolution data, field work and agro-meteorological models. The project was guided by a project strategy group with members from the United States Agency for International Development - Famine Early Warning System Network (USAID-FEWSNET), Directorate General for Development (DG-DEV), Consultative Group on International Agricultural Research - International Wheat Improvement Center (CGIAR-CIMMYT), European Commission Joint Research Center (EC-JRC), United Nations World Food Programme (WFP) and United Nations Food and Agricultural Organisation (FAO). The goal of the project in Stage 1 (March 2003 –November 2004) was to consolidate an early warning system for food security. This started off by an intensive literature review and setting up an initial service for the Centre de Suivi Ecologique (CSE) in Dakar Senegal. In the second Phase of Stage 1 activities focussed more on the actual service delivery and setting up activities with users. Those activities included the monitoring agricultural production for Senegal, monitoring agriculture in Malawi and giving support to the Crop and Food Supply Assessment Mission (CFSAM) of FAO /WFP. Additionally, services were set up for the centre Agro-Hydro-Météorologique (AGRHYMET) as a result of a meeting between AGHRYMET and Vlaamse Instelling voor Technologisch Onderzoek (VITO). During 2005 the early warning service was continued to support GMFS users although there was at that time no formal contract to do so. At the start of the Second Stage, in October 2005, a GMFS user executive board, consisting of one representative from: EC-JRC, FAO, WFP, Southern Africa Development Community Regional Remote Sensing Unit (SADC-RRSU), Regional Centre for Mapping of Resources for Development (RCMRD) and AGRHYMET, was set up to support the consortium in defining the correct services and to review the work. Since the focus for the Second Stage was on up scaling the consolidated services, it was decided that the early warning service and support to the CFSAM were to be continued, the agricultural mapping service was to be expanded to more countries - namely, Senegal, Sudan, Ethiopia, Malawi and Zimbabwe - and extra services on yield modeling using remote sensing and agro-meteorological models were to be provided. During the second year of this stage, the services were even more extended with, support to the Ministry of Agriculture and Meteorological Department in Mozambique, extra activities in Ethiopia and Sudan and support to the regional centers on operational use of the ESA Data Dissemination System (DDS).

This paper examines the agency cost of winner-picking in multidivision firms and uses explicit incentive contracts to analyze the interaction between corporate headquarters' investment and incentive policies. Winner-picking, i.e. the efficient reallocation of scarce resources in an internal capital market, adds an extra layer of noise to the moral hazard problem of incentivizing division managers to produce the resources that can then be redistributed. In particular, division managers with strong future investment opportunities anticipate that headquarters will bail them out should they fail to produce enough resources themselves. This reduces incentives to create the resources in the first place with possible consequences for the optimal investment policy. [less ▲]

RESUME : Cette étude a pour but d’adapter à la population belge l’algorithme FRAX® récemment publié par l’Organisation Mondiale de la Santé (OMS) et permettant de calculer, dans les deux sexes, le risque absolu de fractures ostéoporotiques, à 10 ans. Nous nous sommes attachés à quantifier le risque fracturaire correspondant aux critères actuellement appliqués, en Belgique, pour le remboursement des médicaments de l’ostéoporose et à identifier les situations cliniques correspondant à une probabilité équivalente de fracture. Les probabilités fracturaires ont été calculées, à partir des incidences de fractures et de décès publiées, pour la population belge. Ces probabilités prennent en considération l’âge, le sexe, l’existence de facteurs cliniques de risque (FCR) et la densité minérale osseuse (DMO), mesurée au niveau de la zone propre du col fémoral. L’algorithme FRAX® permet d’identifier différents scénarios d’intervention, en Belgique, correspondant à un risque fracturaire identique ou supérieur à celui servant de base aux critères actuels de remboursement des médicaments. Il est donc possible de recommander une modification des attitudes actuelles, délaissant une stratégie basée sur une évaluation dichotomique de la DMO, au profit d’une intégration progressive des FCR qui permettra, in fine, une meilleure identification des patients à risque accru de fracture. Cette approche devra être substantiée par des analyses pharmaco-économiques appropriées. [less ▲]

Several learning algorithms in classification and structured prediction are formulated as large scale optimization problems. We show that a generic iterative reformulation and resolving strategy based on the progressive hedging algorithm from stochastic programming results in a highly parallel algorithm when applied to the large margin classification problem with nonlinear kernels. We also underline promising aspects of the available analysis of progressive hedging strategies. [less ▲]

The paper discusses elementary control strategies to control the phase of an oscillator. Both feedforward and feedback (P and PI) control laws are designed based on the phase response curve (PRC) calculated from the linearized model. The performance is evaluated on a popular model of circadian oscillations. [less ▲]

Aims: Left ventricular (LV) shape and LV dyssynchrony are two cofactors associated with functional mitral regurgitation (MR) in patients with heart failure. Both can be accurately examined by real-time three-dimensional echocardiography (3DE). We examined the relationship between dynamic MR and exercise-induced changes in LV shape and synchronicity using 3DE. Methods and results: Fifty patients with systolic LV dysfunction underwent 2D and 3D quantitative assessment of LV function, shape, and synchronicity at rest and during symptom-limited exercise test. According to the magnitude of change in MR, patients were divided into EMR group (15 patients, 30%), if the degree of MR increased during test, and NEMR group. During exercise, the changes in LV volumes and ejection fraction were similar in both groups, whereas changes in mitral valvular deformation parameters, in LV sphericity index, and in the extent of LV dyssynchrony were more pronounced in the EMR group. At rest, only the 3D sphericity index could distinguish the two groups. By stepwise multiple regression model, dynamic changes in the systolic dyssynchrony index, sphericity index, and coaptation distance were associated with dynamic MR (r2 = 0.45, P = 0.012). Conclusion: Dynamic MR during exercise is related to the 3D changes in LV shape and in LV synchronicity. [less ▲]

Ces dernières années, la pollution de l’air est devenue une préoccupation pour ses impacts environnementaux et sur la santé. Les réglementations contrôlant les émissions d’air pollué se sont d’ailleurs multipliées. Face à ces problèmes, des solutions de traitement ont été développées, certaines utilisant même les potentialités des microorganismes pour épurer les effluents industriels. Les limites de ces traitements biologiques classiques sont même en voie d’être repoussées par une nouvelle génération de systèmes : les réacteurs biphasiques. [less ▲]

Dans le contexte actuel de crise, le secteur laitier est en difficulté. Il devient alors essentiel de maîtriser les coûts liés à chaque phase d’élevage tout en optimisant la croissance des jeunes animaux. La première mise à l’herbe est, dans ce cadre, une étape importante et sensible. Cependant, la méconnaissance de cet aspect de la part des éleveurs et le recours à des pratiques bien souvent inappropriées engendrent des frais superflus sans garantir de manière systématique l’état sanitaire du cheptel.
