Central Locations across Spatial Scales: A Quantitative Evaluation for Italy Using Census Enumeration District Indicators
نویسندگان
چکیده
‘Marginal’ urban settlements can be assumed as specific locations within a metropolitan area that are unable to attract (incoming) commuter flows. The official statistical system of Italy (headed by the National Statistical Institute, Istat) introduced summary index ‘urban marginality’ following original definition proposed national, ad hoc Parliamentary Committee and assessing together social vulnerability material deprivation at sufficiently detailed spatial scale. More specifically, index—intended composite indicator territorial marginality with normative meaning—was calculated elaboration commuting matrix derived from decadal population censuses considering municipal-level resolution. In this perspective, ability given municipality bigger (or smaller) inflows than outflows, indicates demand for services allowing identification (respectively) central places peripheral locations. Starting described above, our study generalizes approach wider background context, investigating roles scale geographical coverage. By providing novel (functional) centrality periphery, we analyzed patterns submunicipal level, indirectly focusing on processes local development. A clustering standardized polarization quantifying home-to-work daily travels delineated (homogeneous) areas taken sinks (centers) or sources (peripheries) empirical results also demonstrate neighborhoods (i.e., contiguity order) did not affect functional classification territory clustering. Our provides dynamic innovative interpretation hierarchy using simplified data censuses.

متن کاملCombining Information Across Spatial Scales
Spatial and spatial-temporal processes in the physical, environmental, and biological sciences often exhibit complicated and diverse patterns across different spacetime scales. Both scientific understanding, often reflected in computer models, and observational data vary in form and content across scales. We develop and examine a Bayesian hierarchical framework by which the combination of such ...

Introduction: As a complex phenomenon occurring due to a long period of poor precipitation, drought causes water scarcity in the soil and the hydrological system via hydrological, bringing about long-term consequences which may lead to severe economic, environmental, and social problems worldwide. Droughts are classified into four types: meteorological (rainfall), agricultural (soil’s moisture)...
