SIX NUANCES D'A-GREY-GATION L'influence du choix des unités spatiales d'agrégation sur la lecture et l'interprétation des résultats cartographiés
2017
National audience; En même temps que les activités humaines se sont informatisées, les sources de données géographiques se sont diversifiées, autant du point de vue de leur production (smartphones, capteurs, simulation) que de leur gestion (modélisation, base de données et protocoles d’interrogation). Ces données de « nouvelle génération » partagent en général le fait d’être massives, désagrégées et multidimensionnelles. Elles se caractérisent par des attributs riches d’un point de vue spatial (localisation), thématique (type d’activité) et temporel (heure de début et de fin, durée). En contrepartie, leur volume et leur structure les rendent difficilesà manipuler (Batty, 2013 ; Kitchin, 201…
Improving neglect by TMS.
2006
Hemispatial neglect refers to the defective ability of patients to explore or act upon the side of space contralateral to the lesion and to attend to stimuli presented in that portion of space. Evidence from animal models suggests that many of the behavioural sequelae associated with visual neglect may result not solely from the size of the lesion, but also from a pathological state of increased inhibition exerted on the damaged hemisphere by the contralesional hemisphere. On the basis of these potential mechanisms underlying neglect, in this review we discuss therapeutic approaches, focusing particularly on recent research using transcranial magnetic stimulation (TMS). This technique, besi…
Assessment and inter-comparison of recently developed/reprocessed microwave satellite soil moisture products using ISMN ground-based measurements
2019
Soil moisture (SM) is a key state variable in understanding the climate system through its control on the land surface energy, water budget partitioning, and the carbon cycle. Monitoring SM at regional scale has become possible thanks to microwave remote sensing. In the past two decades, several satellites were launched carrying on board either radiometer (passive) or radar (active) or both sensors in different frequency bands with various spatial and temporal resolutions. Soil moisture algorithms are in rapid development and their improvements/revisions are ongoing. The latest SM retrieval products and versions of products that have been recently released are not yet, to our knowledge, com…
WebGIS Implementation for Dynamic Mapping and Visualization of Coastal Geospatial Data: A Case Study of BESS Project
2021
Within an E.U.-funded project, BESS (Pocket Beach Management and Remote Surveillance System), the notion of a geographic information system is an indispensable tool for managing the dynamics of georeferenced data and information for any form of territorial planning. This notion was further explored with the creation of a WebGIS portal that will allow local and regional stakeholders/authorities obtain an easy remote access tool to monitor the status of pocket beaches (PB) in the Maltese Archipelago and Sicily. In this paper, we provide a methodological approach for the implementation of a WebGIS necessary for very detailed dynamic mapping and visualization of geospatial coastal data
European Integration and Baltic Sea Region: Diversity and Perspectives
2011
This publication presents a collection of research papers in conjunction with the international conference “ European Integration and Baltic Sea Region: Diversity and Perspectives” , 26–27 September 2011 at the University of Latvia, Riga. The conference is hosted by the Doctoral School for European Integration and Baltic Sea Region Studies, recently established at the university. The publication is a conference volume – Volume I in an anticipated series of publications featuring research papers by doctoral students issued in two-year intervals. -- All contributions have been double-blind peer reviewed.
Diagnosis and predictability of intraseasonal characteristics of wet and dry spells over equatorial east Africa
2010
Most of Eastern Africa has arid and semi-arid climate with high space-time variability in rainfall. The droughts are very common in this region, and often persist for several years, preceded or followed by extreme floods. Most of the livelihoods and socio-economic activities however remain rain-dependent leading to severe negative impacts during the periods of occurrence of climate extremes. It has been noted that one extreme event was capable of reversing national economic growth made over a period of several years. Thus no sustainable development can be attained in eastern Africa without effective mainstreaming of climate information in the development policies, plans and programmes. Many…
Telpisko prasmju novērtēšanas testa digitālās versijas izstrāde
2021
Maģistra darbā izpētīta telpiskās uztveres un kognitīvo procesu teorija, kas ietver procesu komponentes, references ietvarus, telpiskās spējas, telpisko spēju pielietojumu dažādās nozarēs, telpisko spēju atšķirības starp dažādiem indivīdiem un informāciju par telpisko spēju novērtēšanu ar telpisko testu palīdzību. Pēc teorijas izpētes, tika izstrādāts telpisko prasmju novērtēšanas rīks, kas tika izmantots cilvēku testēšanai, lai noteiktu telpiskās spējas kontekstā ar izglītības un profesionālo nozaru virzienu, kur tās var būt noderīgas un pat nepieciešamas. Izmantojot izstrādāto telpisko spēju novērtēšanas rīku, tika ievākti dati un veikta iegūto rezultātu analīze, kā arī izdarīti secinājum…
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…
Non-interleaved Quadtree Node Codification
2004
The usual quadtree node non-pointer codification is based on interleaved binary representations of node coordinates, in such a way that every operation that concerns to the spatial position or to the specific orientation of the region represented by the node needs to undo this interleaving process. So, the computation time of such operations is linear with the node depth. In this paper an alternative codification is presented called “non-interleaved codification”. The new codification has a simpler management and a higher intuitiveness than current codifications that use the interleaving approach. The proposed codification is more efficient than previous ones for the following set of operat…
