La valeur et la vulnérabilité des espaces agricoles du département du Doubs : identification et évaluation multicritère des espaces agricoles
2019
This paper is part of the update of the atlas of the value and vulnerability of agricultural areas in the French territory of Doubs. It is a project initiated by the French “Direction Départementale des Territoires”, carried out in 2012 by the ThéMA laboratory, and whose update began in January 2019. The objective is to create a decision-making tool for spatial planning and development, for sustainable spatial management. This work presents the method for identifying agricultural areas in the Doubs and their evaluation based on a multi-criteria analysis built on four indices: environmental, spacial structure, financial assistance and labelling.
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…
Estudio de variación en el uso de atenuación I: Hacia una descripción de patrones dialectales y sociolectales de la atenuación en español
2020
Resumen La atenuación es un fenómeno pragmático de gran complejidad que se ha convertido en objeto de estudio priorizado en las últimas décadas, en las que se ha abordado, especialmente, desde disciplinas que trabajan con el habla, como la pragmática y el análisis del discurso. Uno de los aspectos menos trabajado en relación con las estrategias de atenuación en español, no obstante, es la variabilidad sociopragmática y geolectal en usos y recursos de atenuación. Este último es el cometido fundamental de este trabajo -que se complementa con la investigación presentada en el artículo de Albelda y Cestero (en este mismo volumen, 2020)-, en el que se pretende dar cuenta del estado actual de la …

2017
Aquesta compilació inclou actualitzacions nomenclaturals i taxonòmiques per al catàleg de plantes vasculars descrites de les Illes Balears. Aquesta actualització inclou plantes descrites entre 2008 i 2016 a més de correccions per a altres tractades en treballs anteriors.
From soil to soil-less in horticulture: quality and typicity
2013
In this review, the technique of soil-less cultivation of horticultural crops is analysed, the main differences between this and traditional cultivation techniques are described, and the advantages and disadvantages of each method in relation to the others are identified. Soilless cultivation has revolutionised various sectors of vegetable and floriculture production, and recent years have also seen interest being shown by Italian fruit crop producers, particularly those involved in table grape viticulture. The various issues related to the use of this technique are described in relation to the needs of the substrate, water management, and mineral nutrition of the different species, and to …
Regional metacommunities in two coastal systems: spatial structure and drivers of plant assemblages
2014
Aim Biogeographical patterns in metacommunities are still poorly understood, and different processes are expected to occur in different habitats. We analysed the regional plant metacommunities of coastal habitats to test whether (1) the influence of space and climate differs between two habitats differentiated along the seashore–inland gradient, and (2) regional variation in species composition of these habitats can be ascribed to different metacommunity paradigms. Location The entire coast of the Iberian Peninsula, south-western Europe. Methods We collected data on the plant species composition of coastal sites on sand dunes across 3000 km of coastline. The sites were classified into two h…
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Comparisons, Categories, and Labels: Investigating the North–South Dichotomy in Europe
2021
The paper presents genealogy-oriented analysis of how the Nordic model gained its dominant characterization as modern, advanced and superior to other European welfare models while Southern European countries came to be labelled laggards in the welfare domain. To illuminate the relational nature of these, and all, comparisons, the analysis accentuates how researchers, politicians, and civil servants alike designate Nordic and Southern European states, their societies, and their welfare models. The empirical analysis focuses on scholarly writings about welfare-state comparisons (1986–2017) and on European Union documents addressing cohesion policies (1986–2021). Analysis of the vocabulary and…
Des « petits » vignobles en émergence en Bourgogne : éléments d’une dynamique en cours
2015
International audience; La dynamique récente des petits vignobles de l’Yonne, de la Côte-d’Or et peut-être de la Saône et Loire illustre en tout cas une fois de plus le modèle de développement et la pérennité des vignobles de qualité de R. Dion fondé sur le détachement de l’orbite des villes et des voies du commerce facile (comme ce fut le cas pour la Côte-d’Or). Cependant dans le cas présent, il s’agit d’un modèle inversé où le rapprochement des élites urbaines favorise aujourd’hui au contraire les nouveaux vignobles de qualité péri-urbains, les vignobles de l’Yonne bénéficiant de cet effet en raison du rapprochement facilité par les voies de communication, le tourisme vert et patrimonial …
