Mobile Search - Social Network Search Using Mobile Devices
2008
During the last years progress in Web search engines has been made to the point that relevant information can be reached easily most of the time. However very little empirical research has been carried to study Web search in highly dynamic social network environments composed of mobile devices. The aim of this work was therefore to investigate novel approaches that took advantage of the social network environment inherent to mobile peer-to-peer paradigm. The work focused mainly on the development of a prototype for mobile search concept. The prototype was built on top of Drupal content site management system. This study suggests that the methods presented can be a complement to traditional …
Towards automatic assessment of government web sites
2013
This paper presents an approach for automatic assessment of web sites in large scale e-Government surveys. The approach aims at supplementing and to some extent replacing human evaluation which is typically the core part of these surveys.The heart of the solution is a colony inspired algorithm, called the lost sheep, which automatically locates targeted governmental material online. The algorithm centers around classifying link texts to determine if a web page should be downloaded for further analysis.The proposed algorithm is designed to work with minimum human interaction and utilize the available resources as best possible. Using the lost sheep, the people carrying out a survey will only…
The relevance of the French rural policy by the yardstick of the theories of justice
2010
The relevance of the French rural policy by the yardstick of the theories of justice How to evaluate the relevance of the French rural policy ? When the question is to what extent the objectives of the policy are reached owing to public interventions, the method is relatively well known. However, when the question is to what extent these objectives are relevant, an important problem is faced : the referential of this evaluation is indefinite. In this article, we propose to define this referential on the basis of moral and political philosophy : The objectives are relevant if they are derived from a conception of justice that is itself relevant. From this viewpoint, the relevance of the curr…
How green neighbourhoods make cities more compact?t? A 2D microeconomic perspective
2014
National audience; We analyse the emergence of scattered residential development, a key characteristic of sprawl. We analyse a 2D urban economic model with neighbourhood interactions among households (social contacts) and with farmers (who produce green amenities). Starting from a cross-shaped road network and CBD, we analytically establish the existence and characteristics of residential leapfrogging that breaks up the compact development of the city. We extend our analysis by numerical experiments based on observed or econometrically estimated parameters. We nd that the shape of built up areas in uences the decision or not to jump over undeveoped land or to stick to the contiguous urban f…
Fractal dimension versus density of built-up surfaces in the periphery of Brussels
2007
International audience; This paper aims at showing the usefulness of the fractal dimension for characterizing the spatial structure of the built-up surfaces within the periurban fringe. We first discuss our methodology and expectations in terms of operationality of the fractal dimension theoretically and geometrically. An empirical analysis is then performed on the southern periphery of Brussels (Brabant Wallon). The empirical analysis is divided into two parts: first, the effect of the size and shape of the windows on the fractal measures is empirically evaluated; this leads to a methodological discussion about the importance of the scale of analysis as well as the real sense of fractality…

Managing Metro Manila
2017
Metro Manila residents are confronted everyday with the challenges of flooding, substandard housing and horrendous traffic. In this low altitude plain, any significant rainfall raises water levels in many small streams, and contributes to traffic jams. The rapid population growth of the metropolis has led to the proliferation of squatter areas, including alongside flood-prone rivers and railroad tracks. The lack of discipline and of decent garbage management contribute in turn to a worsening of floods when streams are covered with litter. The fast rise in motorization rates, coupled with the many imperfections of the public transport system, make Manila one of the most congested cities in t…
A NEW DIALETICS CENTRE/PERIPHERY: CONSUMPTION PATTERNS AND PRACTICES IN THE SUBURBAN AREAS
2014
This paper deals with the analysis of current changes which have been recently shaping unprecedented urban structures in some suburban areas, due to the emerging of new consumptions spaces. In particular, the work aims at highlighting the effect of urban sprawl on the main Sicilian metropolitan areas, also moulded by the diffusion of the suburban retailing formats, in order to evaluate to what extent these dynamics have been contributing to the configuration of new urban landscapes and unprecedented socio-economic structures, not to mention the support in the process of containing social and economic marginalisation.
On poles and centers: Cities in the French style
2005
International audience; The “multicentric city” is an oversimplified view of the contemporary city. The term “center” covers a multi-faceted reality. A center is not only a concentration of activities. It also means domination,power, creation and interaction. Consequently, the “secondary centers” do not necessarily replicate the main center and they are clearly differentiated. We define the “pole” as a concentration ofactivities, whatever their nature, and the “center” as a concentration of high-order and strategic activities, so that the so-called multicentric cities may be both multipolar and monocentric. This suggests what we call the Multipolar-Monocentric hypothesis.The paper sets out …
When the growth of the town produces gardens
2019
The metropolis is a mother of gardens (Migge, 1919): in the beginning of the twenty 113 century, Leberecht Migge understood that the housing reform of the Modern Movement was also the reform of the urban orchards that could expand in wide common spaces between the buildings. The parks, in which the towns finally could stay in, included a humanized nature, organized in productive and leisure areas. Migge’s envisagement of “Stadtland” had many affinities with the “Extending town” by Giuseppe Samonà based on the shape as single matrix of built and cultivated spaces (Samonà, 1976). Both architects, forty years from each other and in different places of work - Germany and Italy - considered ur…
