El camino hacia la integración de sistemas de gestión de la información científica : el TCD (Trinity College Dublin) como estudio de caso. CERIF y euroCRIS

Pablo de Castro, Director de GrandIR, describió la visión que el Grupo euroCRIS tiene de la infraestructura integrada de gestión de la información científica, compuesta por un sistema CRIS institucional, un repositorio de publicaciones y un repositorio de datos y software, y presentó el modelo de infraestructura integrada del Trinity College Dublin (TCD) como estudio de caso internacional. El sistema CRIS del TCD (TCD Research Support System o RSS), desde su primera versión en 2002, está basado en el estándar CERIF, un modelo de descripción de la actividad científica que está adquiriendo una progresiva relevancia como base de los sistemas CRIS en Europa, particularmente en el Reino Unido. Se citaron en la presentación los ensayos para incorporar CERIF al modelo de datos del software ePrints de repositorios, habilitándolo así para soportar parte de las tareas de recolección de información que realiza un CRIS, y la progresiva cobertura de CERIF a ámbitos tales como la gestión de datos de investigación.

Implementation of IPM programs on European greenhouse tomato production areas: Tools and constraints

Whiteflies and whitefly-transmitted viruses are some of the major constraints on European tomato production. The main objectives of this study were to: identify where and why whiteflies are a major limitation on tomato crops; collect information about whiteflies and associated viruses; determine the available management tools; and identify key knowledge gaps and research priorities. This study was conducted within the framework of ENDURE (European Network for Durable Exploitation of Crop Protection Strategies). Two whitefly species are the main pests of tomato in Europe: Bemisia tabaci and Trialeurodes vaporariorum. Trialeurodes vaporariorum is widespread to all areas where greenhouse industry is present, and B. tabaci has invaded, since the early 1990’s, all the subtropical and tropical areas. Biotypes B and Q of B. tabaci are widespread and especially problematic. Other key tomato pests are Aculops lycopersici, Helicoverpa armigera, Frankliniella occidentalis, and leaf miners. Tomato crops are particularly susceptible to viruses causingTomato yellow leaf curl disease (TYLCD). High incidences of this disease are associated to high pressure of its vector, B. tabaci. The ranked importance of B. tabaci established in this study correlates with the levels of insecticide use, showing B. tabaci as one of the principal drivers behind chemical control. Confirmed cases of resistance to almost all insecticides have been reported. Integrated Pest Management based on biological control (IPM-BC) is applied in all the surveyed regions and identified as the strategy using fewer insecticides. Other IPM components include greenhouse netting and TYLCD-tolerant tomato cultivars. Sampling techniques differ between regions, where decisions are generally based upon whitefly densities and do not relate to control strategies or growing cycles. For population monitoring and control, whitefly species are always identified. In Europe IPM-BC is the recommended strategy for a sustainable tomato production. The IPM-BC approach is mainly based on inoculative releases of the parasitoids Eretmocerus mundus and Encarsia formosa and/or the polyphagous predators Macrolophus caliginosus and Nesidiocoris tenuis. However, some limitations for a wider implementation have been identified: lack of biological solutions for some pests, costs of beneficials, low farmer confidence, costs of technical advice, and low pest injury thresholds. Research priorities to promote and improve IPM-BC are proposed on the following domains: (i) emergence and invasion of new whitefly-transmitted viruses; (ii) relevance of B. tabaci biotypes regarding insecticide resistance; (iii) biochemistry and genetics of plant resistance; (iv) economic thresholds and sampling techniques of whiteflies for decision making; and (v) conservation and management of native whitefly natural enemies and improvement of biological control of other tomato pests.

Metropolitan Areas in Spain and Italy

Metropolitan areas concentrate the main share of population, production and consumption in OECD countries. They are likely to be the most important units for economic, social and environmental analysis as well as for the development of policy strategies. However, one of the main problems that occur when adopting metropolitan areas as units of analysis and policy in European countries is the absence of widely accepted standards for identifying them. This severe problem appeared when we tried to perform comparative research between Spain and Italy using metropolitan areas as units of analysis. The aim of this paper is to identify metropolitan areas in Spain and Italy using similar methodologies. The results allow comparing the metropolitan realities of both countries as well as providing the metropolitan units that can be used in subsequent comparative researches. Two methodologies are proposed: the Cheshire-GEMACA methodology (FUR) and an iterative version of the USA-MSA algorithm, particularly adapted to deal with polycentric metropolitan areas (DMA). Both methods show a good approximation to the metropolitan reality and produce very similar results: 75 FUR and 67 DMA in Spain (75% of total population and employment), and 81 FUR and 86 DMA in Italy (70% of total population and employment).

Sumak Kawsay, or the concept of living well, and perceptions about natural, urban and rural areas: the case of Cuenca (Ecuador)

This research explores critical environmental concepts from the standpoint of political ecology. It contrasts the Ecuadorian Kichua indigenous concept of Sumak Kawsay (i.e., living well), with discourses about natural, urban and rural areas. Sumak Kawsay was included in Ecuador’s 2008 constitution as an alternative to the neoclassical idea of development. This work reveals interesting insights from a variety of social and political viewpoints from both rural and urban areas. The research is based on the medium sized city of Cuenca, which is located in the southern Ecuadorian Andes. We used an adaptation of the Q Method to investigate stakeholders’ perceptions. Four remarkably well-defined viewpoints were revealed. Although these views contrast strongly with Sumak Kawsay, it is possible to transform this paradigm in the foundation of Cuenca’s public policies and institutional structure.

Efecte de la recurrència dels incendis sobre la vegetació i el sòl a les zons de bosc del Macizo Central Ourensano

En els últims 30 anys, el número d’incendis patits a Galicia han augmentat de manera important. En el Massís Central Ourensano l’home ha utilitzat el foc com a eina de gestió forestal per tal de permetre pasturar al bestiar i per tal de recuperar terres per a pastos i culius. Aquesta pràctica ha generat grans extensions de matollar sec europeu on hi hauria d’haver formacions boscoses. Partim de la necessitat de recuperar zones de bosc i ecosistema original i per això mesurem el comportament de les diferents espècies que trobem al matollar y al bosc en aquestes altituds davant la pertorbació que suposen els incendis recurrents. Per realitzar això s’ha mostrejat la vegetació de zones cremades en moments diferents o repetides vegades, mesurant superfície i alçades així com nombre d’individus de cada espècie. També s’han analitzat perfils del sòl per tal de conèixer amb més detall les característiques de cada zona. S’ha observat mitjançant el mostreig com per a la recuperació del matollar el factor determinant és el temps, encara que no trobem un sòl de bona qualitat i profund, en una mitjana de 8 anys trobem un matollar ben desenvolupat amb una bona diversitat d’espècies i grau de cobertura. En canvi, per tal d’arribar a un estat de la successió vegetal on trobem un bosc és necessari que existeixin comunitats arbòries a prop per tal de que arribin individus al matollar desenvolupat. Cal aleshores treballar en l’educació de la població i en la cerca d’alternatives a la gestió forestal vigent, donant èmfasi en la valoració econòmica dels ecosistemes en bon estat i facilitant que aquest bon estat proporcioni beneficis a la població local. Per això cal generar una infraestructura per atraure un turisme rural respectuós amb el medi al mateix temps que es duen altres iniciatives com la implantació de centrals de biomassa als pobles que puguin proporcionar calefacció o aigua calenta. Generant llocs de feina i estalvis a la població d’una zona on l’economia encara es basa potencialment en la ramaderia. Al mateix temps l’esforç monetari dedicat a les plantacions ha de dedicar-se a generar espais al territori amb espècies autòctones com el roure en aquells matollars que presentin condicions adients per a recuperar el bosc.

Optimization of floor cleaning coverage performance of a random path-planning mobile robot

Floor cleaning is a typical robot application. There are several mobile robots aviable in the market for domestic applications most of them with random path-planning algorithms. In this paper we study the cleaning coverage performances of a random path-planning mobile robot and propose an optimized control algorithm, some methods to estimate the are of the room, the evolution of the cleaning and the time needed for complete coverage.

Automatic low baseline stereo in urban areas

In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth observation satellite. This setting makes both views of the scene similarly, thus avoiding occlusions and illumination changes, which are the main disadvantages of the commonly accepted large-baseline configuration. There still remain two crucial technological challenges: (i) precisely estimating DEMs with strong discontinuities and (ii) providing a statistically proven result, automatically. The first one is solved here by a piecewise affine representation that is well adapted to man-made landscapes, whereas the application of computational Gestalt theory introduces reliability and automation. In fact this theory allows us to reduce the number of parameters to be adjusted, and tocontrol the number of false detections. This leads to the selection of a suitable segmentation into affine regions (whenever possible) by a novel and completely automatic perceptual grouping method. It also allows us to discriminate e.g. vegetation-dominated regions, where such an affine model does not apply anda more classical correlation technique should be preferred. In addition we propose here an extension of the classical ”quantized” Gestalt theory to continuous measurements, thus combining its reliability with the precision of variational robust estimation and fine interpolation methods that are necessary in the low baseline case. Such an extension is very general and will be useful for many other applications as well.

New Trends in Public Facility Location Modeling

The past four decades have witnessed an explosive growth in the field of networkbased facility location modeling. This is not at all surprising since location policy is one of the most profitable areas of applied systems analysis in regional science and ample theoretical and applied challenges are offered. Location-allocation models seek the location of facilities and/or services (e.g., schools, hospitals, and warehouses) so as to optimize one or several objectives generally related to the efficiency of the system or to the allocation of resources. This paper concerns the location of facilities or services in discrete space or networks, that are related to the public sector, such as emergency services (ambulances, fire stations, and police units), school systems and postal facilities. The paper is structured as follows: first, we will focus on public facility location models that use some type of coverage criterion, with special emphasis in emergency services. The second section will examine models based on the P-Median problem and some of the issues faced by planners when implementing this formulation in real world locational decisions. Finally, the last section will examine new trends in public sector facility location modeling.

An assessment of empirical Bayes and composite estimators for small areas

We compare a set of empirical Bayes and composite estimators of the population means of the districts (small areas) of a country, and show that the natural modelling strategy of searching for a well fitting empirical Bayes model and using it for estimation of the area-level means can be inefficient.

Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press

Sports and journalism ethics: the coverage of 2012 London Olympics in the British, North-American and Spanish press is a research focused on analysing the treatment that the quality press of three countries (United Kingdom, United States of America and Spain) will carry out in the London Olympic Games. Through a solid methodological approach based on the combination of the qualitative content analysis and qualitative indepth interviews, the investigation will study if the media provide a quality coverage,that is, if they adequate their pieces to the fundamental principles of journalistic deontology (truth, justice, freedom and social responsibility). Furthermore, the research will assess if the selected media comply with the prescriptions established in the ethical codes, stylebooks, newsroom statutes and national and international recommendations about journalism ethics, ranging from each media’s guidelines to key transnational codes established by the UNESCO, the International Federation of Journalists (IFJ) orthe Council of Europe.

Study of the variability in chemical composition of bark layers of Quercus Suber L. from different production areas

Cork is the bark of the cork oak tree (Quercus suber L), a renewable and biodegradable raw bioresource concentrated mainly in the Mediterranean region. Development of its potential uses as a biosorbent will require the investigation of its chemical composition; such information can be of help to understand its interactions with organic pollutants. The present study investigates the summative chemical composition of three bark layers (back, cork, and belly) of five Spanish cork samples and one cork sample from Portugal. Suberin was the main component in all the samples (21.1 to 53.1%), followed by lignin (14.8 to 31%), holocellulose (2.3 to 33.6%), extractives (7.3 to 20.4%), and ash (0.4 to 3.3%). The Kruskal-Wallis test was used to determine whether the variations in chemical composition with respect to the production area and bark layers were significant. The results indicate that, with respect to the bark layer, significant differences were found only for suberin and holocellulose contents: they were higher in the belly and cork than in the back. Based on the results presented, cork is a material with a lot of potential because of its heterogeneity in chemical composition
