CHILDHOOD ADVERSITIES AND HOME ATMOSPHERE AS DETERMINANTS OF DISABILITY AND UNEMPLOYMENT PENSION

2017

Childhood adversities have been linked with adverse life events, but less is known about the long-term effects of childhood home atmosphere in terms of work career. We investigated whether childhood adversities and home atmosphere were associated with disability or unemployment pension. In the Helsinki Birth Cohort Study (born 1934–44), 2001 cohort members had data available on 9 childhood home atmosphere items e.g. whether it was supportive or warm (sum score 0–36, higher score indicating more favorable atmosphere), and 9 childhood adversities e.g. unemployment, parent’s long-term illness or divorce (sum score 0–9, coded into no; one; and two or more) assessed in 2001–04. Of those, 1528 ha…

Posted Migration and Segregation in the European Construction Sector

2015

Worker ‘posting’ or temporary migration of manual workers sent by their employers to work on projects abroad has become increasingly prominent in the European construction industry. It is now normal to find groups of workers from all around Europe on construction sites, living in nearby temporary accommodations, moving on to other projects or back home when the project is complete. This article highlights the interaction between the social and spatial segregation and transnational mobility of these workers in the European Union construction labour market. We argue that the work-focused and employer-dominated nature of the posted workers' social world abroad contributes to their segregation …

Spatial Autocorrelation in Econometric Land Use Models: An Overview

2021

International audience; This chapter provides an overview of the literature on econometric land use models including spatial autocorrelation. These models are useful to analyze the determinants of land use changes and to study their implications for the environment (carbon stocks, water quality, biodiversity, ecosystem services). Recent methodological advances in spatial econometrics have improved the quality of econometric models allowing them to identify more precisely the determinants of land use changes and make more accurate land use predictions. We review the current state of the literature on studies which account explicitly for spatial autocorrelation in econometric land use models …

Potential implications of climate change and urbanization on watershed hydrology

2017

Abstract This paper proposes a modeling framework able to analyze the alterations in watershed hydrology induced by two recurrent drivers for hydrological changes: climate change and urbanization. The procedure is based on the coupling of a stochastic weather generator with a land use change model for the generation of some hypothetical scenarios. The generated scenarios are successively used to force a physically-based and spatial distributed hydrological model to reconstruct the basin response under different conditions. Several potential climate alterations are simulated by imposing negative and positive variations in the mean annual precipitation and a simultaneous temperature increase.…

The (Evolving) vineyard’s age structure in the valencian community, Spain. A new demographic approach for rural development and landscape analysis

2019

Vineyards have assumed a key role as rural landmarks in recent decades. Investigating vineyard dynamics and contexts may reveal various economic, cultural, and environmental aspects of rural landscapes, which can be linked to land-use changes and major soil degradation processes, including soil erosion. As a contribution to rural landscape studies, the purpose of this work is to investigate the spatial distribution of vineyard plots in the Valencian community, located in the eastern area of the Iberian Peninsula, focusing on the final product, the type of vineyard and how long each vineyard has been settled over time. The work provides a comprehensive analysis of a wine-growing landscape, c…

OPTIMIZING STOCHASTIC SUSCEPTIBILITY MODELLING FOR DEBRIS FLOW LANDSLIDES: MODEL EXPORTATION, STATISTICAL TECHNIQUES COMPARISON AND USE OF REMOTE SEN…

Il presente lavoro di ricerca è stato sviluppato al fine di approfondire approcci metodologici nell'ambito della sucscettibilità da frana. In particolare, il tema centrale della ricerca è rappresentato dal tema specifico dell'esportazione spaziale di modelli di suscettibilità nell'area mediterranea. All'interno del topic specifico dell'esportazione di modelli predittivi spaziali sono state approfondite tematiche relative all'utilizzo di differenti algoritmi o di differenti sorgenti, derivate da DEM o da coperture satellitari. The present work has been developed in order to enhance current methodological approaches within the big picture of the landslide susceptibility. In particular, the ce…

Análisis geodemográfico y planificación territorial en España

2002

This article studies the current role of geodemographic analysis in Spanish spatial planning; its importance, gaps and problems. This is done both from a theoretical and planning perspectives. The theoretical perspective studies the references to the population in the legal norm of the several forms of planning, and in particular in the very recent Autonomous Regions' laws. The planning perspective refers to the specific spatial plans that have been aproved. The article identifies three types of spatial planning: urban planning, town and country planning and environmental planning. Therefore, excluding the sectorial planning with spatial incidence.

Behavioral profile of intermittent vs continuous access to a high fat diet during adolescence

2018

Abstract Over the past few years, the effects of a high-fat diet (HFD) on cognitive functions have been broadly studied as a model of obesity, although no studies have evaluated whether these effects are maintained after the cessation of this diet. In addition, the behavioral effects of having a limited access to an HFD (binge-eating pattern) are mostly unknown, although they dramatically increase the vulnerability to drug use in contrast to having continuous access. Thus, the aim of the present study was to compare the effects of an intermittent versus a continuous exposure to an HFD during adolescence on cognition and anxiety-like behaviors, as well as to study the changes observed after …

Housing conditions modulate the reinforcing properties of cocaine in adolescent mice that binge on fat

2017

Abstract Binge eating is a specific form of overeating characterized by intermittent, excessive eating. To date, several studies have addressed the effects that bingeing on fat has on the rewarding effects of drugs of abuse, but they have found contradictory and highly variable results. Housing conditions could modulate these results, as most studies employ isolated animals to measure the exact amount of food that is ingested. The aim of this study was to evaluate the effects of housing conditions on the response of mice to cocaine, modulated by bingeing on a high-fat diet during adolescence. After 40 days of binge-eating for 2 h, three days a week (PND 29–69), the reinforcing effects of a …

Apport de la topographie par LiDAR aéroporté à la caractérisation volumique et spatiale d’amas de déchets sidérurgiques. L’exemple des ateliers de Mo…

2022

Parmi les grands districts de production de fer brut connus, la Puisaye (Bourgogne du nord – Yonne et Nièvre) figure parmi les plus importants à l’échelle métropolitaine, si ce n’est à l’échelle européenne. Plus de 2500 amas de déchets, marquant l’emplacement d’ateliers de réduction du minerai de fer, sont ainsi connus en prospections (Piétak et al. 2012). Les résultats des travaux engagés depuis 2017 dans le cadre d’un Projet Collectif de Recherche, financé par la DRAC Bourgogne-Franche-Comté et le CNRS, ont permis de révéler la continuité de ces activités de production du fer depuis le premier âge du fer jusqu’au second Moyen âge. Pour la période antique, ces amas de déchets se caractéris…
