This paper distinguishes among three types of generosity of social security systems: average generosity, generosity towards early retirement and generosity towards the poor. On the basis of theoretical predictions, it examines the statistical correlations among those types of generosity for 14 OECD countries over the period 1985-2000. It also shows how they have evolved over time and tries to relate this evolution to the process of economic integration. There are three main findings, the first one being a positive relation between average social security spending and poverty alleviation. There is the negative relation between average spending and inequality reduction. Finally, over the period 1985-95 one sees that poverty alleviation increases on average, but to a degree that decreases with economic openness. [less ▲]

We address the topic of real-time analysis and recognition of silhouettes. The method that we propose first produces object features obtained by a new type of morphological operators, which can be seen as an extension of existing granulometric filters, and then insert them into a tailored classification scheme. Intuitively, given a binary segmented image, our operator produces the set of all the largest rectangles that can be wedged inside any connected component of the image. The latter are obtained by a standard background subtraction technique and morphological filtering. To classify connected components into one of the known object categories, the rectangles of a connected component are submitted to a machine learning algorithm called EXtremely RAndomized trees (Extra-trees). The machine learning algorithm is fed with a static database of silhouettes that contains both positive and negative instances. The whole process, including image processing and rectangle classification, is carried out in real-time. Finally we evaluate our approach on one of today's hot topics: the detection of human silhouettes. We discuss experimental results and show that our method is stable and computationally effective. Therefore, we assess that algorithms like ours introduce new ways for the detection of humans in video sequences. [less ▲]

Based on a non linear quasi-steady wind model, this paper presents the statistical characteristics of the wind loading. These statistical characteristics are computed in an analysical way and validated thanks to a Monte Carlo simulation.After this validation, a parametric study allows giving some general observations concerning the non Gaussianity of the loading. Statistical moments up to the fourth order are computed in an analytical way. The subsequent relations are expressed as a function of the slope and curvature of the aerodynamic coefficients. They are a usefull tool for the assessment of the non Gaussianity of the wind loading on any bridge deck. This is illustrated for three famous European bridges. [less ▲]

Le transport de la charge de fond de plusieurs rivières du massif ardennais (Belgique) a été analysé grâce à différentes techniques de marquage de galets (peinture, charge métallique, émetteurs radio). Ces rivières possèdent un bassin versant dont la taille est comprise entre 0,3 et 2700 km². Les observations ont permis de mettre en évidence le débit à partir duquel débute le charriage. Pour des rivières importantes (bassin versant supérieur à 500 km²), cette mise en mouvement se produit pour des débits légèrement inférieurs au débit à plein bord (0,7 à 1 Qb), débits qui se présentent en moyenne 5 à 11 jours par an. Dans les rivières ardennaises de taille intermédiaire (bassin versant compris entre 100 et 500 km²), on constate que le charriage débute pour un débit proche de 0,5 fois le débit à plein bord, avec des récurrences de l’ordre de 0,3 an et une durée de charriage variant entre 8 et 12 jours par an. Dans les rivières de dimension modeste (bassin versant inférieur à 100 km²), il apparaît que la mise en mouvement de la charge de fond se produit pour des débits compris entre 0,5 et 0,8 Qb, mais la récurrence de ces débits est relativement faible et le charriage peut se produire jusqu’à 20 jours par an. Par ailleurs, le transport solide par charriage a été évalué à l'aide de pièges à sédiments dans les rivières de petite dimension (bassin versant inférieur à 10 km²) ; il est relativement peu important dans les bassins forestiers (de l'ordre de 0,5 t.km-².an-1), notamment en raison de la multiplication des embâcles végétaux qui accroissent la rugosité et provoquent une forte dissipation d'énergie. Dans les rivières plus importantes, le transport solide a été estimé entre 0,4 et 2,5 t.km-².an-1 grâce à l'analyse des quantités curées systématiquement aux mêmes sites et à la réalisation de levés topographiques de contrôle. Nous avons ensuite analysé l’évolution des quantités charriées en fonction de la puissance spécifique au plein bord développée par ces rivières. La relation établie sur la base de ces données a permis de mettre en évidence le déficit en sédiments de certaines rivières ainsi que plusieurs facteurs influençant le charriage. [less ▲]

In this paper, I review various questions related to the relationships between banks and private clients, taking into account the impact of the entry into force of the Belgian Code of Private International Law. Among the questions analysed, I review the position of the bank when faced with clients who are married and the impact of the law of marriage. I also review the impact of the death of a client - what are the duties imposed to the bank, how can the bank deal with prospective heirs. All of this focusing exclusively on cross-border relations and hence on questions of applicable law. [less ▲]

Previous studies have described high levels of polychlorobiphenyls (PCB), polybrominated diphenylether (PBDE), toxaphene, ,p0-dichlorodiphenyltrichloroethane (DDT), and ,p0-dichlorodiphenyldichloroethylene (DDE) in the blubber of the harbour porpoise from the North Sea raising the question of a potential endocrine disruption in this species. In the present study, the thyroids of 57 harbour porpoises from the German and Danish (North and Baltic Seas), Norwegian, and Icelandic coasts have been collected for histological and immunohistological investigations. The number of follicles and the relative distribution of follicles, connective, and solid tissues (%) were quantified in the thyroid of each individual. Then, the potential relationship between the thyroid morphometry data and previously described organic compounds (namely, PCB, PBDE, toxaphene, DDT, and DDE) was investigated using factor analysis and multiple regressions. Thyroid morphology differed strongly between ampling sites. Porpoises from the German (North and Baltic Seas) and Norwegian coasts displayed a high percentage of connective tissues between 30 and 38% revealing severe interfollicular fibrosis and a high number of large follicles (diameter >200 lm). A correlation-based principal component analysis (PCA) revealed two principal components explaining 85.9% of the total variance. The variables PCB, PBDE, DDT, and DDE compounds loaded highest on PC1 whereas toxaphene compound loaded most on PC2. Our results pointed out a relationship between PC1 (PCBs, PBDE, DDE, and DDT compounds) and interfollicular fibrosis in the harbour porpoise thyroids. Such an association is not alone sufficient for a cause–effect relationship but supports the hypothesis of a contaminant-induced thyroid fibrosis in harbour porpoises raising the question of the longterm viability in highly polluted areas.
