The idea of amalgamation for the Brussels municipalities is already an old one. In addition to the numerous parliamentary attempts to return to the situation of before 1795, when eight Brussels municipalities formed an administrative unit, there were also the Holvoet Report of 1936 and the establishment of the State Commissariat for the Large Agglomerations during the Second World War. In 1942, «Gross Brüssel» was created, but it was dissolved after the liberation. Except for the proposals of the Union of (...) Cities, things remained rather quiet until the first amalgamation operation of 1971. Brussels was not involved in these amalgamation operations primarily because of the complexity of the Brussels problem over which the Flemish and the French speaking groups could not come to an agreement. The recent proposals can be placed into three categories : a complete amalgamation of the 19 municipalities into one entity, a partial amalgamation of 3 to 10 entities, the status quo. Since the amalgamation means an increase in the municipal expenses because of equalisation of the services in the sub-municipalities at a higher level, integral amalgamation of the present 19 municipalities offers no solution for the financial difficulties besetting these municipalities. In addition,this integral amalgamation solution generales negative reactions from the people of Brussel, who see in it a demand of the Flemish Movement. (shrink)

This classic work in the philosophy of physical science is an incisive and readable account of the scientific method. Pierre Duhem was one of the great figures in French science, a devoted teacher, and a distinguished scholar of the history and philosophy of science. This book represents his most mature thought on a wide range of topics.

Duhem's 1908 essay questions the relation between physical theory and metaphysics and, more specifically, between astronomy and physics–an issue still of importance today. He critiques the answers given by Greek thought, Arabic science, medieval Christian scholasticism, and, finally, the astronomers of the Renaissance.

These selections from Le système du monde, the classic ten-volume history of the physical sciences written by the great French physicist Pierre Duhem (1861-1916), focus on cosmology, Duhem's greatest interest. By reconsidering the work of such Arab and Christian scholars as Averroes, Avicenna, Gregory of Rimini, Albert of Saxony, Nicole Oresme, Duns Scotus, and William of Occam, Duhem demonstrated the sophistication of medieval science and cosmology.

"This volume assembles twelve texts published between 1892 and 1915.... The editors allow one to see the genesis of the ideas of Duhem, philosopher and historian, of the variety of his styles, and sometimes also the limits of his work.... A useful index, probably unique in the field of Duhemian studies, completes the book.... The English-language public may be assured an exemplary translation and a reliable critical apparatus." --Jean Gayon, _Revue d'Histoire des Sciences_.

We consider a two-patch epidemiological system where individuals can move from one patch to another, and local interactions between the individuals within a patch are governed by the classical SIRS model. When the time-scale associated with migration is much smaller than the time-scale associated with infection, aggregation methods can be used to simplify the initial complete model formulated as a system of ordinary differential equations. Analysis of the aggregated model then shows that the two-patch basic reproduction rate is smaller than (...) the 1 patch one. We extend this result to a linear chain of P patches . These results are illustrated by some examples for which numerical integration of the system of ordinary differential equations is performed. Simulations of an individual based model implemented with a multi-agent system are also carried out. (shrink)

Augustin a découvert la Bible tardivement et progressivement, à Milan, puis en Afrique. Il ne l'a pas lue d'emblée entièrement. Il l'a utilisée sous des formes diverses, celle qu'il rapportait d'Italie, celles qu'il rencontrait en Afrique, dans les Églises catholiques et chez les donatistes, celles aussi que Jérôme venait de produire . En dépit de sa préférence pour la Septante, Augustin a toujours recherché le meilleur texte. Dans le prolongement de sa conversion et au contact de la Bible, son herméneutique (...) aussi s'est transformée. Des observations sont faites à propos de Ct 1,6-7 , Jr 10,2-9 et Ac 1,1-3. (shrink)

La vetus latina d'Esther traduit fidèlement la plus ancienne forme grecque de ce livre, Jean-Claude Haelewyck l'a montré dans son édition critique. Nous disposons donc au total de trois formes grecques d'Esther en plus de l'hébreu. C'est l'occasion d'un regard sur le statut de ce ces formes profondément différentes dans la recherche exégétique et dans les Églises. Esther n'est pas le seul cas.

L'examen des diverses combinaisons des ordres des évangiles et des ordres bibliques des Quatre Vivants permet de montrer que l'identification des évangélistes avec les Vivants a visé d'abord à exprimer l'unité de l'Évangile un et quatre avant de caractériser leurs différences. Trois systèmes ont prévalu dans l'antiquité. Dans le plus ancien, Marc est identifié à l'Aigle ; dans un autre système, Marc est identifié à l'Homme ; dans le système reçu, finalement Marc est identifié au Lion . A l'origine, l'Apocalypse (...) est le lieu biblique fondamental, mais en Orient puis en Occident, Ézéchiel supplante l'Apocalypse. La conjonction de l'ordre reçu des évangiles et de la séquence des Vivants en Ez 1,10 a donné le système habituel depuis S. Jérôme: Mt = Homme; Mc = Lion; Lc = Taureau; Jn = Aigle. (shrink)

In this paper, we present a deterministic time discrete mathematical model based on multiregional periodic matrices to describe the dynamics of Sardina pilchardus in the Central Atlantic area of the Moroccan coast. This model deals with two stages (immature and mature) and three spatial zones where sardines are supposed to migrate from one zone to another. The population dynamics is described by an autonomous recurrence equation N ( t + 1) = A . N ( t ), where A is (...) a positive matrix whose entries are estimated using data collected during biannual acoustic surveys carried out from 2001 to 2003 onboard the Norwegian research vessel “Dr Fridtjof Nansen”. The dominant eigenvalue λ of A that gives the long-term growth rate of fish population is smaller than one. This agrees with the stock decrease observed in the data collected. We show that λ is highly sensitive to the recruitment rate and much less sensitive to the reproduction rate. These results can clearly be used to define an efficient scenario in order to fight for instance against a stock decrease. (shrink)
