Changes in Spatial and Sectoral Patterns of Employment in Ile-de-France, 1978-97
2006
This paper investigates the spatial distribution of employment in the region of Ile-de-France in 1978 and 1997. Exploratory spatial data analysis is used to identify employment centres and a sectoral analysis of the central business district (CBD) and sub-centres is performed. The results highlight a process of suburbanisation of employment in Ile-de-France between 1978 and 1997. A more polarised space emerges in 1997 than in 1978, with several employment centres specialised in different activities. Moreover, even if the spatial influence of the CBD declines over the study period, the CBD maintains its economic leadership by concentrating a large variety of high-order producer services.
Exploring the feasibility of introducing electric freight vehicles in the short food supply chain: A multi-stakeholder approach
2021
Abstract The transition towards more sustainable approaches in the Food Supply Chain was concretely visible in the implementation of alternative models, like the Short Food Supply Chain. Some authors raise doubts on the environmental impact of this model, in particular for the externalities caused by the transport system, suggesting the adoption of Electric Freight vehicles. By adopting a multi-stakeholder approach, the objective of this study is to explore both the barriers and potentialities involved in the adoption of Electric Freight vehicles in the Short Food Supply Chain, and the existence of a shared strategy at the system level able to foster their adoption. Results suggest that, fo…

Governing the Metropolitan Dimension: A Critical Perspective on Institutional Reshaping and Planning Innovation in Italy
2019
As in other European countries, over recent decades the question of metropolitan government has captured political and academic attention in Italy too. The debate has been recently fuelled by a national reform introduced to create 14 metropolitan authorities to provide for new government solutions in the territories of the larger urban areas. Based on literature and empirical observation, this paper presents a critical view of that process by examining the following questions: How do metropolitan areas relate to broader Italian urban policy? How does the reform contribute to a reshaping of multi-level governance through national and local initiatives? And how does institutional reorganisati…
Reviving the EU project: from values to new territorial development models
2020
Le but de cet article est d’analyser les relations entre l'aménagement du territoire, la cohésion territoriale (comme but à atteindre et comme politique) et les valeurs qui sous-tendent le projet de l'Union européenne (UE). Les territoires, les cultures et l’histoire des pays de l'UE peuvent jouer un rôle afin de redéfinir l'UE comme modèle social et politique de référence à l'échelle mondiale. Dans la « nouvelle grande transition » (écologique, économique, sociale, urbaine, féministe, démocratique…), la dimension territoriale et les politiques publiques jouent un rôle clé dans la définition des futurs possibles : nouveau modèle de développement économique, nouveaux modèles spatiaux et nouv…
The total social costs of constructing and operating a high-speed rail line using a case study of the Riyadh-Dammam Corridor, Saudi Arabia
2019
Introducing a High-Speed Rail technology between the Saudi Arabian cities starts raising many challenging issues of different nature ranging from technical to operational, which require huge investments in infrastructure, operations and maintenance. Background information about the development of HSR worldwide to date is included. However, the main aim of this paper is to determine a methodology to estimate the full cost of travel and provide insights into the working model developed to include the calculations of the total social costs of building a new HSR line for the Riyadh-Dammam corridor in Saudi Arabia and understand in what circumstances it is a suitable technology to use. The Sprea…
How relevant are local climate zones and urban climate zones for urban climate research? Dijon (France) as a case study.
2018
17 pages; International audience; Several typologies of urban surface properties have been proposed, in recent years, for urban heat island studies and climate modeling. Some were specifically developed for cities and urban climate issues, like the Urban Climate Zones, and the more recent Local Climate Zones. The initial objective of this paper is to evaluate the capacity of these two typologies to identify thermal environments in and around cities, and to determine which typology best captures the daily spatio-temporal patterns of surface and urban canopy heat islands. To simulate urban climate with a model, LULC data based on a given typology are required. To avoid circularity, we combine…
Seismic Behavior of Lisbon Mixed Masonry-RC Buildings With Historical Value: A Contribution for the Practical Assessment
2018
The fact that linear analysis is still the most used procedure in the design engineering offices, studies which addresses issues associated to the estimation of the structural behavior factor values are relevant. In this study, the behavior factor of a particular type of mixed masonry-reinforced concrete buildings in Lisbon is estimated. The typology chosen in this study represents 30% of building stock in Lisbon; these buildings were built between 1930 and 1960 and thus were designed without considering the seismic-design requirements proposed in current codes. The evaluation of the behavior factors was based on the use of nonlinear static analyses, performed in the form of the sensitivity…
Clustering cities through urban metrics analysis
2017
[EN] This paper describes a process for measuring and characterizing urban morphological zones. These urban zones are delineated for the entire area of Spain, independently of administrative boundaries and excluding demographic data, using a high resolution land-use dataset. Given the rich information available on land cover and subsequently assigned population data, it is possible to calculate a set of urban spatial metrics to classify these urban zones into homogenous morphological groups. Four types of urban agglomerations are identified in Spain by working with these urban metrics and applying a final cluster analysis. Although these groups have a general complex monocentric typology, e…
