Spatial centrality, economic vitality/viability: compositional and spatial effects in Greater London
No full textThis research is the continuation of previous studies in the literature related to space syntax spatial
analyses of urban centrality. In recent years spatial economics has focused on the spatial location
of economic activities and its determinants. At the city-region level a significant part of the analysis
has been concerned with the concept of agglomeration as a source of economies of scale,
productivity growth, and the role of transport: the spatial accessibility economies. Empirical
evidence of the relationship between multi-scales spatial accessibilities and movement economies,
as dependant on spatial configuration, is well charted in the space syntax literature. Using space
syntax spatial analyses, the socio-economic and spatial patterns of 10 centres located in Inner and
Outer London are analysed. The findings show that centres have specific spatial configuration
signatures which distinguish centres from their spatial context. These signatures lead to the
identification of centre spatial factor components. The interaction between socio-economic
compositional effect and spatial signature profiles is investigated and leads to preliminary centre
socio-economic/spatial typologies
Spatial design economies
No full textThe digital revolution has enabled an influx of data that has allowed us to analyse cities in ways that could never previously be anticipated. How, though, might this data be constructively applied in a manner that could shape and improve not only urban patterns, but also people's economic and social prospects? Alain Chiaradia looks at how space syntax spatial analyses might enable spatial design economies in the future, with special reference to London and the Borough of Tower Hamlets in particular

CALIBRATION OF DISTRIBUTED SHALLOW LANDSLIDE MODELS IN FORESTED LANDSCAPES
Full text linkIn mountainous-forested soil mantled landscapes all around the world, rainfall-induced shallow landslides are one of the most common hydro-geomorphic hazards, which frequently impact the environment and human lives and properties. In order to produce shallow landslide susceptibility maps, several models have been proposed in the last decade, combining simplified steady state topography- based hydrological models with the infinite slope scheme, in a GIS framework. In the present paper, two of the still open issues are investigated: the assessment of the validity of slope stability models and the inclusion of root cohesion values. In such a perspective the “Stability INdex MAPping” has been applied to a small forested pre-Alpine catchment, adopting different calibrating approaches and target indexes. The Single and the Multiple Calibration Regions modality and three quantitative target indexes – the common Success Rate (SR), the Modified Success Rate (MSR), and a Weighted Modified Success Rate (WMSR) herein introduced – are considered. The results obtained show that the target index can 34 003_Bischetti(569)_23 1-12-2010 9:48 Pagina 34 significantly affect the values of a model’s parameters and lead to different proportions of stable/unstable areas, both for the Single and the Multiple Calibration Regions approach. The use of SR as the target index leads to an over-prediction of the unstable areas, whereas the use of MSR and WMSR, seems to allow a better discrimination between stable and unstable areas. The Multiple Calibration Regions approach should be preferred, using information on space distribution of vegetation to define the Regions. The use of field-based estimation of root cohesion and sliding depth allows the implementation of slope stability models (SINMAP in our case) also without the data needed for calibration. To maximize the inclusion of such parameters into SINMAP, however, the assumption of a uniform distribution of probability of the parameters must be overtaken. In small and steep catchments where there is an intrinsic susceptibility to instability phenomena, moreover, an additional class of low probability of instability (0.81)<1.0) has been proposed to better discriminate the areas classified as unstable.</p
Optical properties of the clean and slowly oxidized surface of silicon
No full textThe optical absorption of an UHV cleaved (111) surface of Si has been investigated as a function of the exposure to oxygen. Data concerning the disappearing of surface states with oxidation are reported. The sticking coefficient for oxygen of a clean surface of Si is calculated from optical absorption data
