The paper provides a perspective on the development of the Belgian disability insurance system. Using both survey and administrative data, it sketches a picture of the (changing) factors leading towards disability, as well as the outcomes in terms of program participation. The paper shows the key role of integrating other forms of early retirement programs into the analysis. The main findings are an unspectacular trend in the number of DI beneficiaries over time combined with a strong expansion of (early-) retirement schemes. [less ▲]

A. Context One of the objectives of the European Construction Products Directive (CPD) is to harmonize the technical specifications with regard to dangerous substances and construction materials. Construction products could emit or contain dangerous substances that have been defined as dangerous substances under Commission directives and national regulations. In the future construction products may only be placed on the market in the European Union if they accord with the (second generation) harmonized technical specifications including health aspects and bear the CE mark. B. Objectives The goal of this research project is to improve the flow of knowledge and information vis-à-vis normalisation activities in the domain of indoor air measurements, indoor product emission testing, labeling and certification by proposing an evaluation method and standardized assessment methods for a harmonized approach relating to emissions from building materials into indoor air for implementation in Belgium. This approach will comply with current European harmonizing efforts ongoing on European level. C. Conclusions  International tendencies as well as national developments indicate the growing importance of building material emission testing  Harmonisation of governmental schemes to assess volatile organic emissions in the context of the CPD is necessary to obtain transparency  The topic of different limit values in different countries is a difficult problem to solve  It was demonstrated that it is possible with alternative methods (µ-chamber and FLEC) to achieve a qualitative and quantitative correlation with the reference method. However there is a need to extend this comparative study to more materials  The important influence of the quantification procedure on the emission results was demonstrated  The possiblity to investigate microbial resistance of building materials with the so called µ-chamber technique was demonstrated  A twofold methodology for the odour determination of building materials was developed: a quantitative method based on intensity and a qualitative method based on hedonic scale. Furthermore the basis for the development of an electronic nose specific for evaluation of building materials was laid down  A possible evaluation scheme for Belgium on the basis of AFSSET/AgBB/prEN15052 was proposed with two modifications: - Time path modification (7 or 10 days) - Prescreening with alternative method (< 20 L) D. Contribution of the project in a context of scientific support to transfer of knowledge and innovation This research project for implementation of the essential requirement “Hygiene, health and the environment” of the Construction Products Directive has besides its informative and sensitizing role also performed a supporting role in the development of new innovative low emission construction products. The research project has also ensured a Belgian input in the validation work of the draft standard "Emissions into indoor air" - WI 351009 - Construction products - Assessment of emissions of regulated dangerous substances from construction products - Determination of emissions into indoor air” in development in working group 2 of CEN/TC 351. Furthermore this research project has lead to the development of new innovative test methods tailored to the specific needs of construction products. [less ▲]

This paper analyzes the effect of retirement on cognitive functioning using two large scale surveys. On the one hand the HRS, a longitudinal survey among individuals aged 50+ living in the United States, allows us to control for individual heterogeneity and endogeneity of the retirement decision by using the eligibility age for Social Security as an instrument. On the other hand, a comparable international European survey, SHARE, allows us to identify the causal effect of retirement on cognitive functioning by using the cross-country differences in the age-pattern of retirement. The results highlight in both cases a significant negative, and quantitatively comparable, effect of retirement on cognitive functioning. Our results suggest that promoting labor force participation of older workers is not only desirable to insure the viability of retirement schemes, but it could also delay cognitive decline, and thus the occurrence of associated impairments at older age.

Le présent article analyse les facteurs que les producteurs intègrent aux processus de prise de décisions du choix des cultures et de l’utilisation des produits chimiques de synthèse (PCS) à Dridji, commune de Djidja et les logiques sous tendant ces choix. Les données, collectées auprès de 74 personnes grâce à des entretiens semi et non structurés, d’observations participantes et directes ont été soumises à des analyses de perception et des analyses quantitatives grâce aux outils de la statistique descriptive. Il ressort de l’étude que la décision du choix des cultures est prise par le chef ménage et est déterminée par les objectifs du ménage, les résultats de la campagne antérieure, les caractéristiques des cultures, la disponibilité en main d’œuvre et en PCS, la maîtrise de l’itinéraire technique des cultures. Près de 60% des chefs ménages associent plus leurs épouses que les actifs agricoles à cette décision du fait qu’au sein des ménages (près de 72%), les actifs agricoles sont en majorité des apprenants et donc plus occupés par leur formation le temps que dure celle-ci. Quant à l’utilisation des PCS, elle est déterminée par le type de culture, la connaissance d’alternatives efficaces de lutte contre les ravageurs, la connaissance des effets des PCS sur la santé humaine. Si cette décision est prise par le chef ménage et implique les actifs, elle n’est mise en œuvre que par les hommes bien conscients des dangers liés aux PCS sur l’environnement et la santé humaine.

Forests are biodiversity hotspots worldwide with 70% of terrestrial biodiversity being included in forested landscapes. However, deforestation, forest degradation and fragmentation lead to an increasing rate of species extinctions. Hence, predicting the consequences of changes in species numbers, in distribution patterns of taxa, and of shifts in dominance, has become a major challenge for community and ecosystem ecology. However, until now the relationships between biodiversity and ecosystem functioning in forests have been largely underexplored Therefore, the overall aims of the BELSPO cluster project FORBIO are: to review, synthesize and disseminate existing knowledge about the benefits and drawbacks of mixed stands vs monocultures (WP1); and to establish a highly innovative, large-scaled forest biodiversity experiment to evaluate the impact of increasing tree diversity on forest ecosystem functioning (WP2). To achieve the first objective, a so-called ‘white paper’ has been compiled by the FORBIO team members which has been published in Dutch as a special issue of the BosRevue and in French as a special issue of Forêt Wallone. Among stakeholders, many different opinions exist about the functioning of mixed forests and therefore the scientific evidence was confronted with stakeholder perceptions on ecosystem services in mixed forests compared to monocultures. The principal outcome was that stakeholders appear to have quite strong opinions on the functioning of mixed vs monoculture stands, whereas the review of the scientific literature highlighted the lack of specific information on forest ecosystem services in mixed forests compared to monocultures, in particular from studies where confounding factors can be eliminated or accounted for. The second objective was met by establishing two large-scaled tree diversity experiments in Zedelgem (Flanders) and Gedinne (Wallonia). Based on a state-of-the-art experimental design, 32 810 and 33 304 trees of five different species were planted in 42 and 44 experimental plots in Zedelgem and Gedinne, respectively. A third experiment with a similar design will be established in Hecthel-Eksel (Flanders) in 2011. FORBIO’s short-term contributions to sustainable development are mainly related to the fact that the project has introduced the state-of-the-art concepts and empirical support on the various relationships between biodiversity and ecosystem functioning to a large audience of forest owners, managers, users and scientists in Belgium. In the long-run, FORBIO will significantly contribute to a better understanding of the importance of tree species diversity for the functioning of forest ecosystems and the ecosystem services that they provide thanks to the establishment of the two (and soon three) large-scaled tree diversity experiments. Furthermore, the experiments, embedded in the worldwide TreeDivNetwork, will most likely continue to act as an attractor for researchers from Belgium and abroad. [less ▲]

We consider deterministic optimal control problems with continuous state spaces where the information on the system dynamics and the reward function is constrained to a set of system transitions. Each system transition gathers a state, the action taken while being in this state, the immediate reward observed and the next state reached. In such a context, we propose a new model learning--type reinforcement learning (RL) algorithm in batch mode, finite-time and deterministic setting. The algorithm, named Voronoi reinforcement learning (VRL), approximates from a sample of system transitions the system dynamics and the reward function of the optimal control problem using piecewise constant functions on a Voronoi--like partition of the state-action space.

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).

Ce présent rapport a pour but d’expliquer la démarche de dimensionnement poursuivie pour les 6 solutions de plancher retenues. Ce rapport ne fournit pas un dimensionnement exact des structures de plancher étudiées mais fournit un pré-dimensionnement. Ce dernier a été réalisé sur base d’une série d’hypothèses permettant de simplifier le modèle de calcul. Les dimensions obtenues ne sont dès lors probablement pas les dimensions exactes des éléments structurels mais permettent d’obtenir un ordre de grandeur des dimensions et de la quantité de matériau nécessaire. Le pré-dimensionnement est effectué sur base de l’Eurocode EN 1995-1-1 pour les solutions en bois et EN 1994-1-1 pour les solutions mixtes acier-béton. L’hypothèse principale que nous effectuons est de supposer une connexion complète entre les différents éléments dans le cas d’une solution mixte (acier-béton, bois-bois, bois-acier, …). Cette hypothèse engendre comme conséquence directe que nous sous-estimons les flèches. En effet, nous négligeons le glissement qui pourrait se produire à l’interface des éléments. Pour contre à cela, nous garderons une réserve de l’ordre de 20% sur les flèches par rapport à la limite admissible. En effet, en phase de pré-dimensionnement, il n’est pas judicieux de déjà procéder au calcul des connecteurs et donc à la détermination du degré de connexion entre éléments. [less ▲]

In the Ulster fire test, a large scale composite floor using cellular beams connected to composite slabs will be tested under natural fire. The particularity of the composite floor in this test is that certain cellular beams will be without any fire protection in order to investigate the contribution of membrane effect to overall fire resistance. However, cellular beams could behave in a very different way compared to traditional steel beams because of risk of local phenomenon. The aim of this study was to build a complex FE Model of whole composite floor system with long span cellular beams connected to composite slab in order to take account of 3D membrane effect. This permitted, on the one hand, to find out the right numerical model for this type of composite floor, and on the other hand to define the appropriate structure to be used for the full scale fire test. In order to achieve this latter purpose, a sensitivity study has be carried out in which determinant parameters for ensuring a good membrane effect have been investigated. [less ▲]
