Multi-destination pleasure trip behaviors in Sicily
2010
Many pleasure trips are often characterized by the visit of more than a single destination. The topic is well documented in literature (Cooper 1981; Mings & McHugh, 1992), but the main determinants and consequences of multi-destination trips have not been adequately analyzed (McKercher & Lew, 2004). Moreover, the empirical studies on this topic are limited to a few pioneering studies (Lau & McKercher, 2007; Mings & McHugh, 1992; Wu & Carson, 2008). This lack may be attributable to the failure of tourism organizations to collect data on multi-destination trip behaviors, as it results, for example, from European statistics on tourism (according to the Council Directive 59/95 EC), where no inf…
Analiza przestrzennego zróżnicowania zmian w potencjale infrastruktury transportowej w Polsce
2015
Wiele zachodzących zjawisk, ich rozwój czy kierunki zmian, uzależnionych jest od przestrzennych interakcji pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share (SSSA) został wprowadzony do badań przez S. Nazarę i G.J.D. Hewingsa. Przedstawia on przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury infrastruktury transportowej w województwach Polski w latach 2004 oraz 2014, według rodzajów infrastruktury transportowej z zastosowaniem przestrzennej dynamicznej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa wzr…
Impacts des réseaux viaires sur les mobilités urbaines : quelques illustrations
2008
This research aims to find the impact of the network shape and structure on the urban mobilities, in order to fight against the automobile dependency and to include the externalities in the network design. Three examples illustrate this objective. The first one shows the influence of the network shape on the pedestrian urban flows. The second one emphasizes how sensitive to the network structure is the efficiency of a very flexible Demand Responsive Transport. The third example demonstrates that the network metric is favourable to the automobile and how it can be possible to apply an alternative metric, called the “slow metric” to reduce the urban sprawling and the automobile dependency.
Spatial and temporal variability of rainfall over the Republic of Djibouti from 1946 to 2017.
2021
20 pages; International audience; For the first time, the spatial and temporal variability of rainfall in the Republic of Djibouti is investigated using data from 14 weather stations over the period 1946–2017. Due to limited data availability, high-resolution long-term satellite rainfall products (CHIRPS, PERSIANN-CDR, TAMSATv3, ARC2) and ERA5 reanalysis also contribute to document time–space rainfall variability at monthly, seasonal and annual scales. Principal component analysis identifies two spatially coherent regions of rainfall variability in the east (coastal zone) and the west (inland zone) of the country. Annual rainfall amounts are everywhere very low (60–300 mm), but with contras…
A different glimpse into mobilities: On the interrelations between daily spatial mobility and social mobility
2017
We explore the link between daily spatial mobility and social mobility, taking changes in the contemporary labor market and family as examples. We propose a new theoretical approach to mobility that is defined as a productive force of social labor. Analyzing the relationship between daily spatial mobility and social mobility, we show that spatial mobility has become a strategy of compensation for the lack of social mobility. Explanations for the increase in daily spatial mobility are also provided. Lastly, we reveal how spatial mobility has the capacity to produce major social change, taking the family as an example. peerReviewed
Urban Segregation and Unemployment: A Case Study of Marseille (France)
2015
International audience; In this paper, we study the effects the Marseille’s spatial organization on unemployment. More specifically, differences in characteristics of residential population induce urban stratification so that the urban structure could affect the propensity of unemployment. This potential link is called the reverse causality. In order to evaluate the effect s of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. In a first step, we highlight the realness of residential segregation in Marseille by a topology of neighborhoods by degree of deprivation with a principal com…
Translating User Perspective into Spatial Design
2013
A rapid adoption of ICT innovations transforms the context of human activities and collaboration, the educational settings included. The context change at the same challenges the traditional spatial design paradigm calling for tools and approaches that are applicable to ICT enhanced practices. We take here an ecological approach presenting a work in progress in which we aim to develop a tool for capturing and translating user perspective in order to design innovative learning spaces for vocational education; the case is one of practical nursing. We apply a combination of quantitative and qualitative methods. By focusing on the local practices and user perspective in cultural transition, we …
SST Comparison of AVHRR and MODIS Time Series in the Western Mediterranean Sea
2020
La temperatura de la superficie del mar (SST) es un parámetro clave para comprender los procesos atmosféricos y oceánicos. Desde finales de la década de 1980, las imágenes de satélite infrarrojas se han utilizado para complementar los registros in situ para estudiar la variabilidad temporal y espacial de la SST. El radiómetro avanzado de muy alta resolución (AVHRR) del satélite de la Administración Nacional Oceánica y Atmosférica (NOAA) fue el primer sensor utilizado con éxito para calcular la SST después del desarrollo y validación del algoritmo de corrección atmosférica conocido como 'ventana dividida'. Más recientemente, el espectrorradiómetro de imágenes de resolución MODERADA (MODIS) a…
Simulation and validation of urban dynamics with cellular automata
2018
Cet article, rédigé en 2008, présente les évolutions importantes la plateforme SpaCelle pour simuler l'évolution d'un espace à l'aide d'automate cellulaire. En particulier, la version 5 permet la structuration multi-couches des cellules pour gérer la dynamique de plusieurs variables définies sur un maillage. Elle permet aussi d'utiliser des cellules de type linéaires ou ponctuelles à travers des couches de type réseau. Les différentes couches ont leur propre dynamique et les règles peuvent faire interagir les couches entre elles. Ces fonctionnalités avancées ont permis de construire un nouveau modèle sur l'évolution de l'agglomération rouennaise plus proche de la réalité terrain en utilisan…
Geography of urban and locational conflicts in Valencia and its metropolitan area
2021
Aquest article fa una anàlisi sobre els conflictes territorials sorgits al llarg dels darrers anys, de principis de la dècada de 2000 fins a 2013, a l’àrea metropolitana de València. Amb aquesta anàlisi, volem realitzar una radiografia sobre la conflictivitat territorial d’aquest espai urbà i avançar hipòtesis amb referència a les causes que la van provocar, com també estudiar les connexions espacials que es van establir, de cara a una formulació posterior de recomanacions per a una planificació urbana i territorial i un govern de la ciutat millors. Aquest treball és el resultat d’una recerca sistemàtica sobre conflictes territorials, actors i estratègies en tota mena de disputes relacionad…
