Consumer city

Urban economics has traditionally viewed cities as having advantagesin production and disadvantages in consumption. We argue thatthe role of urban density in facilitating consumption is extremelyimportant and understudied. As firms become more mobile, thesuccess of cities hinges more and more on cities' role as centresof consumption. Empirically, we find that high amenity citieshave grown faster than low amenity cities. Urban rents havegone up faster than urban wages, suggesting that the demandfor living in cities has risen for reasons beyond rising wages.The rise of reverse commuting suggests the same consumer cityphenomena.l     

Histoire et dialectique des idéologies et significations religieuses

The aim of this article is to consider the possibility of a new analytical methodology that could include multidisciplinary approaches into the study of religious ideologies and practices, taking benefit from historical and ethnographic interpretations, but also from linguistic and philological, psychoanalytical, philosophical, sociological, and anthropological considerations. If one tries to study the role or function played by religion in society, considering human beings as builders of symbolic worlds, one should set out to analyze, if not rules, at least general processes of the religious readjustment with respect to the rest of social life, whenever the gap is much too wide, or the religious transfer from one realm to another entirely different.     

CONSTRUCTION COSTS AND THE SUPPLY OF HOUSING STRUCTURE*

ABSTRACT Construction costs account for the bulk of the price of new houses in most markets, but their study has been relatively neglected. We document that there are economically large differences in construction costs across U.S. housing markets. We also estimate a very elastic supply for physical structure; hence, differences in construction activity across markets do not explain the variation in costs. Supply shifters that collectively do account for differences in building costs include the extent of unionization within the construction sector, local wages, local topography in terms of the presence of high hills and mountains, and the local regulatory environment.     

Injection Grouts for the Re-Attachment of Architectural Surfaces with Historic Value—Measures to Improve the Properties of Hydrated Lime Grouts in Slovenia

In the described studies with the aim of optimizing hydrated lime grout composition, the first measure was to reduce the water content of the grout using a highly efficient polycarboxylate ether-based superplasticizer, whereas the second measure was to increase the content of the inert limestone filler with an adequate grain size distribution. In this way, an attempt was made to achieve the best possible volume stability and strength properties of the hydrated lime grout, while continuing to fulfill the other necessary requirements regarding non-structural grouting works which are reported in the literature.

The results of the tests showed that a non-structural grout consisting of 1 volume part of hydrated lime CL 90-S and 3 volume parts of inert limestone filler, with 0.5% of the polycarboxylate ether based superplasticizer, fulfilled most of the established requirements, so that it is thus potentially suitable for re-attachment interventions on architectural surfaces.
