Le prix des paysages périurbains
2007
L'évaluation économique du prix des paysages périurbains utilise des analyses géographiques (occupation des sols, composition paysagère, distance à des biens paysagers, paysages vus : champ de vision, objets, formes). L'article fait le point sur la littérature en matière de méthode et de résultats et présente l'estimation du prix d'attributs paysagers dans la ceinture périurbaine de Dijon.
Free riding as méchanism
1998
Free-riding is methodologically puzzling. It is at the same time important and often not observed as an actual phenomenon. The paper explores the possibility of treating free riding as an underlying or causal mechanism. As such, free riding is to be treated as part of the real world rather than of the world of models or theories. However, the free riding mechanism is particularly prone to operate not in isolation but together with other mechanisms. This feature has consequences on issues such as empirical content, testability or relevance. These questions are discussed in the light of some recent work in philosophy of science and with special attention given to the development of experiment…
Exposure to psychosocial work factors in 31 European countries
2012
Background Although psychosocial work factors are recognized as major occupational risk factors, little information is available regarding the prevalence of exposure to these factors and the differences in exposure between countries. Aims To explore the differences in various psychosocial work exposures between 31 European countries. Methods The study was based on a sample of 14,881 male and 14,799 female workers from the 2005 European Working Conditions Survey. Eighteen psychosocial work factors were studied: low decision latitude (skill discretion and decision authority), high psychological demands, job strain, low social support, iso-strain, physical violence, sexual harassment, bullying…
Benefits of Direct Colposcopic Vision for Optimal LLETZ Procedure: A Prospective Multicenter Study.
2015
International audience; Objective The aim of the study was to assess whether direct colposcopic ă vision (DCV) of the cervix during large loop excision of the ă transformation zone (LLETZ) is associated with a decrease in the volume ă and dimensions of specimens or affects margin status at histology. ă Materials and Methods A prospective multicenter observational study of ă 216 women who underwent LLETZ for grades 2 and 3 cervical ă intraepithelial neoplasia was conducted. The volume and dimensions ă (circumference, length, and thickness) of the surgical specimens were ă measured before fixation. Data were compared according to the use of ă colposcopy during LLETZ. The following 3 groups we…
Disparités sociales en éducation en Afrique sub-saharienne : Genre, localisation géographique et revenu du ménage
2006
06017; Dans ce texte, nous poursuivons deux objectifs complémentaires : le premier consiste à offrir une description de l'ampleur des disparités sociales qui existent dans les systèmes éducatifs des pays de l'Afrique au Sud du Sahara principalement dans la période actuelle mais aussi en lui donnant une perspective temporelle; le second cherche à identifier certains des facteurs qui peuvent rendre compte des disparités constatées ou des actions qui ont visé à les réduire.
Cost and Financing of Education and its Impact on Coverage and Quality of Services and Efficiency and Equity in Sub-Saharan African Countries
2007
07052; In this chapter, we take mostly an international comparative perspective limited to Sub-Saharan African countries. First, we analyse first the macro picture and the public finance dimension, analyzing the systemic choices made in the distribution of public resources across levels and types of education. Second, we move to unit cost estimates and the factors accounting for their level in a given country and to their variation across the different countries of the region. Finally, we examine the implication of the choices made in the financial dimension upon outcomes (coverage and quality of educationl services), birnging issues of efficiency and equity into the analysis.
The effect of agglomeration economies and geography on the survival of accommodation businesses in Sicily
2021
The study explores the geographical pattern of the accommodation industry in the Italian insular region of Sicily, focusing on the determinants of the risk of market exit. We adopt a standard framework of business survival analysis where agglomeration economies play an important role. We then extend the analysis by considering the role of geography to explore whether the risk of market exit depends on nearness to desirable amenities. The geography is here measured by the distance from the coast and the altitude of the place where the firm is located. When we look at the entire population of accommodation firms that started between 2010 and 2014, we find evidence that the risk of failure inc…
Trade is not necessary for agglomeration to arise
2003
We develop a spatial general equilibrium model in which the absence of trade is an endogenous outcome and we show that trade is not a necessarycondition for agglomeration to arise. More precisely, extending the modeldeveloped by Ottaviano et al. [13], we show that equilibria without tradediffer significantly from those obtained in the presence of trade. Somewhatsurprisingly, equilibrium structures without trade are richer than those withtrade, since partial agglomeration becomes a feasible outcome. Equilibrianow depend on the ratio of mobile to immobile factors and an increase in thatratio triggers a process of spatial agglomeration.
Influence économique et concurrence au sein d'une agglomération
1986
La définition d'un indicateur de centralité do chaque zone d'une agglomération peut reposer sur l'utilisation de mesures d'accessibilité (type potentiel) et d'influence des zones considérées. (FUSTIER, GARLANDIERX ROUGET. - 1985). L'indicateur d'influence brute est présentement corrigé pour tenir compte de la concurrence interzones dans l'espace urbain. La définition et les propriétés générales dë l'indicateur d'influence effective sont présentées dans une première partie et illustrées sur un exemple numérique. Une seconde partie est consacrée à la présentation des résultats d'une application au cas de l'agglomération dijonnaise. Plusieurs simulations relatives à diverses répartitions des f…
Centres secondaires et recomposition économique des espaces urbains
2002
The object of this paper is to analyze the multicentric features of the Agglomeration of Dijon by studying the spatial organization of the economic activities and population. The study relates to the territory of the Agglomeration Community of Dijon (COMADI), which is composed of 16 towns. The space scale used is Iris-2000 zoning for the communes of more than 5000 inhabitants and the communal scale for the other towns belonging to the COMADI: the sample includes 114 observations. We use two databases available for two years (1990 and 1999): the SIRENE data for the employment by sectors of activities (ACTET10 and NAF700nomenclatures) and the data of the RGP for the population. We study the s…
