There has been a proliferation of self-construction groups in Germany today in response to the political abandonment of public housing. But these self-contained groups made up of the middle classes are operating within the framework of this politics. These groups aim for individual ownership of housing. They have no interest in the urban integration of their enclave. By contrast there is another type of situational urbanism, not well tolerated by the authorities, that is developing on the margins, in remote places. (...) The particpative urbanism movements were very different, whether these were the Advocacy Planning of the 1970s which developed alternatives to urban projects, or Community Design Centres which worked with ethnic minorities. But this form of organisation tends also to be reclaimed by projects of homogenisation. So what, should be the conditions of intervention for a situated urbanism that is genuinely pluralist and non-hegemonic? (shrink)

Résumé Des groupes d’auto-construction se multiplient aujourd’hui en Allemagne, en réponse à l’abandon d’une politique publique du logement. Mais ces groupes réservés de fait aux classes moyennes sont fonctionnels par rapport à cette politique. Ces groupes visent la propriété individuelle du logement. Ils n’ont aucun égard pour l’insertion urbaine de leur îlot. Il y a par contre un autre urbanisme situationnel, mal toléré des autorités, qui se développe à la marge, dans les lieux écartés. Les mouvements pour l’urbanisme participatif obéissaient (...) à d’autres logiques, depuis l’ advocacy planning des années 1970, qui développait des alternatives aux projets urbains, jusqu’aux Community Design Centers qui travaillent avec les minorités ethniques. Mais cette forme d’organisation tend aussi à être récupérée dans des projets d’homogénéisation. Quelles seraient alors les conditions d’intervention d’un urbanisme situationnel réellement pluraliste et non hégémonique? (shrink)

Previous work showed that the beginning of a sound is more important for the perception of loudness than later parts. When a short silent gap of sufficient duration is inserted into a sound, this primacy effect reoccurs in the second sound part after the gap. The present study investigates whether this temporal weighting occurs independently for different frequency bands. Sounds consisting of two bandpass noises were presented in four different conditions: a simultaneous gap in both bands, a gap in only (...) the lower frequency band, a gap in only the higher frequency band, or no gap. In all conditions, the temporal loudness weights showed a primacy effect at sound onset. For the frequency bands without a gap, the temporal weights decreased gradually across time, regardless of whether the other frequency band did or did not contain a gap. When a frequency band contained a gap, the weight at the onset of this band after the gap was increased. This reoccurrence of the primacy effect following the gap was again largely independent of whether or not the other band contained a gap. Thus, the results indicate that the temporal loudness weights are frequency specific. (shrink)
