Promoting the single-family house in Belgium: the social construction of model housing

Urbanization in Belgium is a process of diffusion rather a process of urban concentration, though the country is very densely populated. In this process the state does not look to have a leading role. The paper examines how the housing policy determines this process of urbanization, namely by promoting the ownership and the individual house. The housing policy, initiated in years of deep social crisis, can only be understood as an upper-class response to the riots in 1886 : the housing policy is intended to give and enforce a social definition of working class, with various interpretation granted by the political opposing forces. The “garden-city” model was then promoted because it allowed to make apolitical compromise between these interpretations. But it was an ideological model with only a few realisations. However it allowed the dominant preference for individual housing to become the real model wich was implemented through the numerous measures wich constitutes the housing policy. In the following stages, a lot of measures came to enlarge the benefit of the public aid to other social groups. From this analysis, it becomes clear that one of the social functions of the housing policy is to enforce the different representations of the social structure wich do no longer need a moralizing discourse because of the hidden connections between the space, the social structure and the policy system.

Les données des 4 dernières années montrent que la détermination aux stades 30-32 du taux d'attaque, généralement inférieur à 10 %, ne permet pas d'évaluer correctement le risque de dégâts à la récolte, ni d'intervenir efficacement contre les infections hivernales précoces. En cas d'infections printanières, non visibles au stade 32, mais conduisant à plus de 75 % de tiges atteintes au stade 75, la combinaison de la protection du pied et du feuillage par un traitement vers le stade 39 a conduit aux augmentations de rendements les plus élevées. Le moment le plus opportun pour l'analyse du taux d'attaque et la prise de décision concernant la modalité de lutte devrait être précisé sur base des conditions météorologiques. [less ▲]

The exterior calculus package EXCALC2, developed by Schrüfer, is used to implement Siklos' method on a computer. By an appropriate choice of the 1-form basis of spatially homogeneous cosmological models, making use of the time-dependent automorphisms of the Lie algebra, it is possible to obtain a compact form of Einstein's field equations for general models of this type. The explicit expression of the equations, obtained with the help of EXCALC2, is given here for two nondiagonal five-dimensional spatially homogeneous models, namely G[SUB]1[/SUB] and G[SUB]8[/SUB]. These equations constitute an ideal tool for the study of the dynamics of these models: an oscillatory behavior has been found for model G[SUB]1[/SUB], while model G[SUB]8[/SUB] exhibits a monotonous kasnerian mode of approach to the initial singularity.

In the present study, we have established and validated a radioenzyme assay which permits us to quantify progesterone metabolism in the chicken brain. Progesterone metabolism was then studied in five brain areas obtained by microdissection from the telencephalon (part of the lobus paraolfactorius immediately rostral to the preoptic area), the preoptic area, and the hypothalamus. Three metabolites of progesterone were produced in large amounts in these brain regions and were quantified in this study: 5 beta-pregnane-3,20-dione (5 beta-DHP) as well as its metabolite 3 alpha-hydroxy-5 beta-pregnane-20-one (5 beta,3 alpha-ol) and 5 alpha-pregnane-3,20-dione (5 alpha-DHP). The unmetabolized progesterone was also recovered and quantified. The 5 beta-reduction of progesterone (production of 5 beta-DHP and 5 beta,3 alpha-ol) was very active but its 5 alpha-reduction (production of 5 alpha-DHP) was almost absent in the lobus paraolfactorius. An opposite pattern of metabolism was found in the preoptic area and the hypothalamus (higher 5 alpha- but lower 5 beta-reductase activity). The changes in progesterone metabolism in these brain areas were then studied in groups of hens submitted to induced egg laying stop and molting. A significant decrease in progesterone 5 alpha-reduction was found in the median hypothalamus of hens during the period of molt. Simultaneously, the experimental procedures induced significant decreases in the production of 5 beta-DHP by the lobus paraolfactorius, anterior, and medial hypothalamus but induced a significant increase in the production of this metabolite in the preoptic area. These changes are likely to be involved in the control of reproductive functions including sexual behavior and secretion of luteinizing hormone-releasing hormone, and a number of possible causal mechanisms are presented. These should now be tested experimentally especially in view of the very limited information which is now available on the biological effects of the metabolites of progesterone. [less ▲]
