Analyse de la distribution spatiale des implantations humaines : apports et limites d’indicateurs multi-échelles et trans-échelles
2020
As human beings, it is easy for us to judge visually whether a distribution is dispersed or concentrated. However, the quantitative formalization of our impressions is problematic. It depends on the scales of the chosen analysis. This dependence of indicators on scales has changed. It is initially considered as a barrier to knowledge, it now reflects the multi-scale organisation of the distributions studied. The central objective of this thesis is to investigate the limits and contribution of multi-scale and trans-scale indicators to the study of the spatial distributions of human settlements.Spatial analysis aims at comparing spatial distributions to a uniform distribution. The way in whic…
A paradigm of extreme rainfall pluvial floods in complex urban areas: the flood event of 15 July 2020 in Palermo (Italy)
2021
Abstract. In the last few years, some regions of the Mediterranean area have witnessed a progressive increase in extreme events, such as urban and flash floods, as a response to the increasingly frequent and severe extreme rainfall events, which are often exacerbated by the ever-growing urbanization. In such a context, the urban drainage systems may not be sufficient to convey the rainwater, thus increasing the risk deriving from the occurrence of such events. This study focuses on a particularly intense urban flood that occurred in Palermo (Italy) on 15 July 2020; it represents a typical pluvial flood due to extreme rainfall on a complex urban area that many cities have experienced in rece…
DEVELOPMENT POLICY MONITORING ISSUES – REGIONAL AND LOCAL EXPERIENCES IN RIGA REGION
2012
Elaboration and use of development policy monitoring instruments promotes applicable and effective policy implementation and decision making, which is based on regular and systematic verification of resources, actions and results. On different policy development levels exists varied approach of defining specific aims and use of policy monitoring measures. Since activation of development monitoring issues in Latvia, some institutions have gained experience in elaboration of monitoring systems among them Riga region and its local municipalities practise various approaches using policy monitoring instruments. Specific study analyzes theoretical aspects of different development monitoring appro…
Suburban Fertility and Metropolitan Cycles: Insights from European Cities
2021
Being largely diversified along the urban–rural gradient, fertility gaps have demonstrated to fuel metropolitan expansion, contributing to natural population growth and social change. In this direction, population dynamics and economic transformations have continuously shaped urban cycles in Europe. Assuming suburban fertility to be a relevant engine of metropolitan growth, the present study investigates and discusses the intrinsic relationship between fertility transitions and urban expansion, focusing on European metropolitan regions. An average crude birth rate referring to the last decade (2013–2018) was estimated from official statistics at 671 Functional Urban Areas (FUAs, Eurostat Ur…
Long-term human occupation of a rural landscape in central-western Sicily (Castro/Giardinello valley and mt Barraù): Harvesting memoires project case…
2017
The “Harvesting Memories” project focuses on the study of long-term landscape transformations as a diachronic result of the interaction between socio-economic human patterns and environmental and ecological trends in a rural area of Central-Western Sicily. The aim of this paper is to present the results of the archaeological survey carried out in Castro/Giardinello Valley and the Mt. Barraù area (Corleone, Palermo). The fieldwork confirmed the long occupation of this area characterized by archaeological evidences dating to the Middle Copper Age/Eneolithic, Bronze Age, Classical period, Middle Ages and Late Modern age. The detection of the high intensity of human presence in this area across…

Transnationalism and Settlement of Latvian Emigrants in the Nordic Countries
2021
The intra-European migration flows have fostered debates about the intentions of migrants to settle in their destination country or return to their countries of origin. Based on a quantitative analysis of survey data ('N' = 1391), this article presents a typology of migration patterns among migrants from Latvia in the Nordic countries. Using two dimensions—attachment to the destination country and attachment to the country of origin—the article identifies and characterises the following four migration patterns: (1) bi-nationals, (2) settlers, (3) footloose migrants and (4) isolated migrants who focus on their country of origin and are willing to return (separated).

La movilidad geográfica de la población extranjera en España : un fenómeno emergente
2002
En este articulo se analizan, a partir de los microdatos de la Estadística de Variaciones Residenciales del período 1988-2001, las características demográficas y los patrones espaciales de las migraciones internas de la población extranjera en España. Entre los principales resultados de este trabajoso destacan: una mayor intensidad migratoria de los extranjeros con relación a los españoles; los extranjeros muestran una gran diversidad de patrones migratorios cuando se consideran diferentes nacionalidades. En este contexto, algunas provincias se caracterizan por ser centros difusores de algunas nacionalidades, como Madrid de los latinoamericanos y Almería de los africanos, y otras son recept…
Temporal dynamic of biofilms enhances the settlement of the central-Mediterranean reef-builder Dendropoma cristatum (Biondi, 1859).
2021
Abstract Research on marine invertebrate settlement provides baseline knowledge for restoration technique implementation, especially for biogenic engineers with limited dispersion ability. Previously, we determined that the maturity of a biofilm strongly enhances the settlement of the vermetid reef-builder Dendropoma cristatum. To elucidate settlement-related biofilm features, here we analyse the structure and composition of marine biofilms over time, through microscopic observations, eukaryotic and prokaryotic fingerprinting analyses and 16S rDNA Illumina sequencing. The vermetid settlement temporal increase matched with the higher biofilm coverage on the substratum and the reduction of th…
