Innovation in Urban Policy: Movement and Incorporation in City Administration and Community Development

While much recent thinking about city administration suggests tinkering with attitudes of administrators, it will be useful to review how administrators and officials encounter deeper social forces: the continuing inequalities and separations of race and class. Cases of "progressive government" experience—in Chicago; Boston; Berkeley; Santa Monica; Burlington, Vermont; and elsewhere—and of community development institutions spread more broadly through US. cities, suggest the outlines of new challenges and response by urban administrators and politicians.     

City and innovation: Different size,different strategy

The objective of this paper is to assess whether establishments' innovation performance and innovation strategies differ by the size of the city in which they are located. Using the Canadian 1999 Survey of Innovation database (establishment-based), it was found that the rate of innovation is not correlated with city-size, but when the innovation measure takes into account the importance of innovation, then the size of the city does matter. The results show that establishments belonging to smaller cities (with populations of less than 50,000) are less likely to be associated with a world-first innovation than those located in larger cities. Four innovation strategies have been retained—Private Source, R&D, Collaboration and Public Science Base paths—and the results show that the R&D path leads to the greatest increase in the estimated probability to be associated with a world-first innovation, for almost all sectors and all city sizes.     

Using Fractal Dimensions for Characterizing Intra‐urban Diversity: The Example of Brussels

The objective of this paper is to compare fractal‐based parameters calculated by different fractal methods for urban built‐up areas and to link the observed spatial variations to variables commonly used in urban geography, urban economics, or land‐use planning. Computations are performed on Brussels, Belgium. Two fractal methods (correlation and dilation) are systematically applied for evaluating the fractal dimension of built‐up surfaces; correlation is used to evaluate the fractal dimension of the borders (lines). Analyses show that while fractal dimension is ideal for distinguishing the morphology of Brussels, each estimation technique leads to slightly different results. Interesting associations are to be found between the fractal dimensions and rent, distance, income, and planning rules. Despite its limitations, fractal analysis seems to be a promising tool for describing the morphology of the city and for simulating its genesis and planning. The model is robust: it replicates the urban spatial regularities and patterns, and could hence fruitfully be integrated into intra‐urban simulation processes.     

Le Grand Abri aux Puces,a Mousterian site from the Last Interglacial: paleogeography,paleoenvironment, and new excavation results

Le Grand Abri aux Puces (GAP), located on the right bank of the Ouvèze River of southern France, has been known to contain well-preserved stone tools and faunal remains, but our work in 2008 was the first professional, controlled excavation at the site and has exposed at least 1 archaeological layer with a very rich and diverse faunal assemblage (23 macrofaunal species, as many for the microfauna, 27 land snail species), abundant charcoals (fragments are large and preserve small twigs with their pith and bark still intact), and stone tools with immaculate surface preservation (retaining their original freshness and preserving microscopic use wear). The information issuing from paleontology, micropaleontology, malacology, and anthracology all place the principle GAP human occupation unambiguously in a temperate climatic phase. Different biometric and biochronological characters of the fauna converge to place the layers found thus far from before the last glacial, and most likely in MIS 5e (127–117 kya). The lithic elements, mainly composed of tools of superior quality, demonstrating particular technical investment, and made from widely distributed raw material sources, lead us to hypothesize brief passages of hunting groups in the cave focused around an anticipated activity. This hypothesis will be refined and tested during further excavations.
