From Analysis to Formulation of Strategies for Farm Advisory Services (Case Study: Valencia – Spain). an Application through Swot and Qspm Matrix
2019
Abstract European agriculture should meet new increasing internal and contextual challenges. For example, the reform of the Common Agricultural Policy in 2003 introduced the cross-compliance, among other novelties, as compulsory for farmers. To better meet this and other requirements, Member States had to set up the so-called Farm Advisory System, operational across the European Union in 2007. From a sample of actors involved in the provision of farm advisory services in the region of Valencia (Spain), the present study aimed to identify the most appropriate strategies to implement such services. SWOT method has been applied to examine the internal and external environment. Based on this di…

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…
On Line Validation Exercise (OLIVE): A Web Based Service for the Validation of Medium Resolution Land Products. Application to FAPAR Products
2014
International audience; The OLIVE (On Line Interactive Validation Exercise) platform is dedicated to the validation of global biophysical products such as LAI (Leaf Area Index) and FAPAR (Fraction of Absorbed Photosynthetically Active Radiation). It was developed under the framework of the CEOS (Committee on Earth Observation Satellites) Land Product Validation (LPV) sub-group. OLIVE has three main objectives: (i) to provide a consistent and centralized information on the definition of the biophysical variables, as well as a description of the main available products and their performances (ii) to provide transparency and traceability by an online validation procedure compliant with the CEO…
Postveritat, escepticisme de recepció i escepticisme d'emissió
2019
Les creences porten a l'acció i en l'acció es manifesten. Actuem segons allò que creiem, i no sempre les nostres creences constitueixen coneixement. Són les creences les que ens menen (atesos uns desitjos determinats) a actuar, i com que aquestes poden ser falses, els nostres intents de vegades es veuen -per aquesta raó- frustrats: les nostres accions no assoleixen l'èxit. En la mesura que les nostres accions afecten altres persones, creences errònies poden dur a cometre injustícies, perjudicis o danys. Per tot això és important formar i transmetre creences vertaderes. Per totes aquestes raons, com a agents epistèmics i també morals, hem de procurar ser fiables a l'hora de formar les nostre…
Coltivazione in vaso di varietà di Capsicum annuum L. ad uso ornamentale
2010
Il peperoncino, originario di ambienti equatoriali e tropicali, ha trovato il suo habitat ottimale di crescita anche nelle zone più calde di diversi Paesi del bacino del mediterraneo. La specie è nota, oltre che per le innumerevoli proprietà curative e medicinali, anche come una delle spezie più apprezzate nella cucina mediterranea. L’elevato valore estetico di alcune varietà, determinato dalla presenza, numerosa e prolungata, e dalla bellezza, nella forma e nel colore, dei frutti, consente la loro utilizzazione anche per fini ornamentali. In tale settore, numerose sono le destinazioni d’uso delle piante di peperoncino, che vanno dal vaso fiorito, per abbellire terrazzi e balconi, alla real…
Hydrogen plasma induced photoelectron emission from metal surfaces
2018
Low temperature hydrogen plasmas are strong sources of vacuum ultraviolet radiation. The properties of laboratory plasmas can be influenced by surface processes induced by photons with their energies exceeding the surface work function of the wall material. In this work, the plasma induced photoelectron emission has been studied with different ion sources. The emission depends on the mechanical design of the plasma device, plasma heating method and the discharge power (density). Parametric studies include the quantifying of the emission from different metal surfaces, commonly used as plasma facing materials in ion sources, as well as alkali metal covered surfaces. Experimental studies sugges…
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.
Essays on social capital and space
2014
The idea of specific values and beliefs as, ceteris paribus, the main explanatory of growth differentials, has recently received lot of attention by social scientists. The focus is in particular to specific shared values and beliefs, constituting a social "stock" of good values fostering growth and cooperation, thus the name, social capital. Unfortunately, social capital is an elastic concept. Moreover, to the extent that social interactions type and strength matter, social capital clearly requires attention for the role of space. Thus, this thesis attempts to clarify some of the issues related to social capital and space. In the first chapter we outline the main questions of this thesis, i…
