Educación para la paz e interculturalidad en ESO: Gandhi, el cine y la música

El presente trabajo se centra en la figura de Gandhi como un ejemplo de lucha pacífica para alcanzar objetivos y resolver conflictos sociales. Alumnos bilingües de segundo curso de Educación Secundaria Obligatoria (ESO) (13 – 14 años) han conocido la biografía de Gandhi a través del visionado de la película sobre su vida y han realizado varias tareas sobre ella. Todas estas actividades de tutoría se han organizado en una webquest, que incluye un análisis de la banda sonora original del film. Esta intervención se ha planteado desde el enfoque de la interculturalidad y la integración social, integrando el uso de las tecnologías de la información y la comunicación (TIC). Todos los estudiantes han desarrollado muchas competencias básicas y otras habilidades necesarias para ser en el futuro adultos responsables y autosuficientes

Conocerles para poder educarles: ¿es realmente diferente el alumnado bilingüe del no bilingüe en 1º de E.S.O.?

El presente trabajo se basa en la premisa de que la educación de los niños y adolescentes debe adecuarse y concretarse todo lo posible a su propia realidad y contexto. De este modo, la mejor manera de proporcionarles la mejor educación académica y, sobre todo, en valores, es conocerlos en la medida de lo posible. Por ello, se ha realizado un estudio comparativo entre dos grupos de alumnos de primer curso de Educación Secundaria Obligatoria (12–13 años) de un mismo centro educativo, a la vista de los desiguales resultados académicos obtenidos por ambos. Uno de estos grupos pertenece a la modalidad educativa bilingüe español-inglés y el otro no, siendo esta la única diferencia a priori. Se ha desarrollado una investigación para averiguar cuáles son las posibles diferencias existentes entre ellos. Las herramientas empleadas han sido actividades interdisciplinares del ámbito de la tutoría planteadas desde el enfoque de la interculturalidad y la integración social e integrando el uso de las tecnologías de la información y la comunicación (TIC). Estas intervenciones se han llevado a cabo en ambos grupos y se han analizado los resultados obtenidos para relacionarlos con las posibles diferencias existentes entre ambos grupos de alumnos

Diseño de una herramienta basada en la generación interactiva de estilos para la visualización de capas a través de un WMS

En el plano de los Usuarios, las Infraestructuras de Datos Espaciales (IDEs), se conciben como las piedras angulares sobre las que realizar operaciones de visualización, análisis y toma de decisiones. La mayoría de los usuarios de datos espaciales no tienen necesidades especiales de visualización. Por esta razón las organizaciones que hacen pública dicha información utilizando las interfaces de Servicios de Mapas en la Web (WMS) definidas por el Open Geospatial Consortium (OGC) definen un estilo de visualización por defecto para la Información Geográfica (IG). Estos estilos de visualización definen los colores, los grosores, los patrones de línea, los rellenos, la tipografía del texto, etc… de una forma genérica, en muchos casos bien cuidada y en la mayoría de los casos utilizan los estilos tradicionales de la Cartografía Oficial. El resto de usuarios “avanzados” de la IG necesita controlar y gestionar la forma en la que se visualiza dicha información de modo que se facilite la toma de decisiones, la legibilidad, etc… Para este tipo de usuarios el OGC ha definido un conjunto de especificación que permite definir los estilos de visualización de las geometrías y atributos entre las que están Style Layer Descriptior (SLD) y Filter Encoding (FE) que permite definir filtros espaciales, lógicos y aritméticos. En este documento se presentan los avances realizados desde el puntos de vista práctico de la implementación de una herramienta que permite a los usuarios interactuar con el servicio WMS y en otros casos con el Servicio de Entidades-Objetos en la Web (WFS) para permitir que dichos usuarios avanzados puedan definir las reglas de visualización que desean aplicar. El diseño e implementación de la herramienta ha sido ideado para que sea portable y para que pueda interactuar con servicios Web conformes con las especificaciones del OGC

Interactive style generation for layer visualisation through a WMS

When visualizing the different layers of geographic information through a map server, the layers are obtained with a pre-defined style virtually never meeting the user's visual needs. A tool has been developed allowing definition and interactive application of the different styles created by the user. The tool allows listing of all layers of a Web Map Service and depending on the type of geometry of everyone of them, the parameters in accordance with the style defined by the user could be chosen, such as colour, thickness, size and text's font style. As a result, a cartographic document in real time is achieved from a map server with the styles defined by the user for every layer, as well as the possibility of interactively changing the layers. It also allows saving of the developed styles in a file that could be applied to another cartographic document at any time. The functioning of the tool is based on server's standard requests, such as GetCapabilities, GetStyles and GetMap that will be successively run according to the user's interaction with the application. The application is essentially based on the specification Style Layer Descriptor [1]. Different XML documents defining styles will be developed with the application. These generated styles will be sent within the GetMap request so as to show the wanted image to the user.

GEOSISMO: Visualisation of Events and Seismologic Characteristics in the Internet

An inventory of seismic movements at global level exists that is based on the data gathered by the seismographers of each observatory. This inventory includes the location and characteristics of the technical equipment of the observatories, as well as the location and date of each earthquake. The inventory is stored in an Access database, and the accelerograms (temporal series of accelerations) are stored in text files. It is proposed that a web service based in a Web Feature Service be created, following the specifications of the OGC (Open Geospatial Consortium), that would visualize the location of the seismographers and of the epicenters of the earthquakes for the spatial and temporal intervals provided. The representation of the places will be a geometric symbol proportional to the PGA magnitude, based on information extracted automatically by the system. When the context (number of elements to represent or zoom level) permit it, the accelerograms will be visualized as scaled in proportion to the magnitude of seismic activity instead of as a geometric symbol. This type of visualization will facilitate interpretation and a rapid decision when the page is consulted. This objective will be enhanced by the possibility of visualizing the information from anyplace that has Internet access, because the tool will be configured as a piece of SDI in conformance with OGC standards

SPECTRAL MIXTURE MODELING TO ESTIMATE WOOD VOLUME IN NORTH OF SPAIN FROM OPTICAL SATELLITE DATA

Information from satellite imagery is an important data source to Forest management. Remote sensing techniques provide information about volume, biomass and other biophysical parameters of forest stands. The main goal of this work is to map the conifer stand volume from Landsat Thematic Mapper (TM) data using Spectral Mixture Analysis (SMA). Fraction images from spectral unmixing show biophysics properties more easily than original bands because they represent physics aspects of ground covers. The work área was El Alto Valle del Ebro (Spain). Two mini-scenes, (50x50km) acquired on March 12th 1996 and July 13th 1996, were used. The applied methodology had three main steps: 1) unmixing the original imagery, the bands 3, 4, 5 and 7 (the most employed in vegetation studies) were used in SMA; 2) these fraction images were related with the over bark volume (OBV) variable (extracted from Second Spanish National Forest Inventory NFI2 ) by means of regression techniques and multivariate analysis; 3) a volume map was obtained using interpolation techniques from the obtained allometric model and the basal area (BA), of considered stand. The main conclusion of this work was the possibility to obtain a model (adjusted R²=0.75) which permitted to estimate the stand volume from medium spatial resolution satellite data. Moreover, the use of this model and with the support of digital ortophotographs allowed an estimated volume map to be obtained

Un caso de queratoma en el casco de un caballo

Los queratomas del casco, son procesos neoplásicos benignos, poco frecuentes, de origen epitelial y que se desarrollan a partir de células productoras de queratina, localizadas en la pared del casco. Normalmente estos procesos están relacionados con una historia previa de claudicación intermitente. En este trabajo describimos las características clínicas, macroscópicas e histopatológicas de un queratoma en el casco de un caballo con una historia clínica de cojera crónica. El animal presentaba una deformación en la ranilla del casco debido a la presencia de una masa localizada en la unión de la banda coronaria con la línea blanca. El estudio histopatológico mostró la presencia de una proliferación neoplásica integrada por células epiteliales con formación de múltiples capas de queratinaKeratomas are uncommon benign neoplasms of the horse hoof with epithelial origin, which are developed from keratin-producing squamous cells of the hoof wall. Normally these processes are related to a previous history of intermittent lameness. Clinical, macroscopic and histopathologic features of a keratoma in the hoof of a horse with a clinical history of chronic lameness are described in this paper. The animal showed a deformity of the hoof frog due to the presence of a mass located at the junction of the coronary band with the white line. A neoplasic proliferation was observed at the histopathologic examination, consisting of epithelial cells and several layers of keratin

Multiplicity dependence of jet-like two-particle correlations in p-Pb collisions at sNN\sqrt{s_{NN}} = 5.02 TeV

Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 $< p_{\rm{T}, assoc} < p_{\rm{T}, trig} <$ 5.0 GeV/$c$ is examined, to include correlations induced by jets originating from low momen\-tum-transfer scatterings (minijets). The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range $|\eta|<0.9$. The near-side long-range pseudorapidity correlations observed in high-multiplicity p-Pb collisions are subtracted from both near-side short-range and away-side correlations in order to remove the non-jet-like components. The yields in the jet-like peaks are found to be invariant with event multiplicity with the exception of events with low multiplicity. This invariance is consistent with the particles being produced via the incoherent fragmentation of multiple parton--parton scatterings, while the yield related to the previously observed ridge structures is not jet-related. The number of uncorrelated sources of particle production is found to increase linearly with multiplicity, suggesting no saturation of the number of multi-parton interactions even in the highest multiplicity p-Pb collisions. Further, the number scales in the intermediate multiplicity region with the number of binary nucleon-nucleon collisions estimated with a Glauber Monte-Carlo simulation.Comment: 23 pages, 6 captioned figures, 1 table, authors from page 17, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/161

Anisotropic flow of charged hadrons, pions and (anti-)protons measured at high transverse momentum in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}}=2.76 TeV

The elliptic, $v_2$, triangular, $v_3$, and quadrangular, $v_4$, azimuthal anisotropic flow coefficients are measured for unidentified charged particles, pions and (anti-)protons in Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV with the ALICE detector at the Large Hadron Collider. Results obtained with the event plane and four-particle cumulant methods are reported for the pseudo-rapidity range $|\eta|<0.8$ at different collision centralities and as a function of transverse momentum, $p_{\rm T}$, out to $p_{\rm T}=20$ GeV/$c$. The observed non-zero elliptic and triangular flow depends only weakly on transverse momentum for $p_{\rm T}>8$ GeV/$c$. The small $p_{\rm T}$ dependence of the difference between elliptic flow results obtained from the event plane and four-particle cumulant methods suggests a common origin of flow fluctuations up to $p_{\rm T}=8$ GeV/$c$. The magnitude of the (anti-)proton elliptic and triangular flow is larger than that of pions out to at least $p_{\rm T}=8$ GeV/$c$ indicating that the particle type dependence persists out to high $p_{\rm T}$.Comment: 16 pages, 5 captioned figures, authors from page 11, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/186

Centrality dependence of charged particle production at large transverse momentum in Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm{NN}}} = 2.76 TeV

The inclusive transverse momentum ($p_{\rm T}$) distributions of primary charged particles are measured in the pseudo-rapidity range $|\eta|<0.8$ as a function of event centrality in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=2.76$ TeV with ALICE at the LHC. The data are presented in the $p_{\rm T}$ range $0.15<p_{\rm T}<50$ GeV/$c$ for nine centrality intervals from 70-80% to 0-5%. The Pb-Pb spectra are presented in terms of the nuclear modification factor $R_{\rm{AA}}$ using a pp reference spectrum measured at the same collision energy. We observe that the suppression of high-$p_{\rm T}$ particles strongly depends on event centrality. In central collisions (0-5%) the yield is most suppressed with $R_{\rm{AA}}\approx0.13$ at $p_{\rm T}=6$-7 GeV/$c$. Above $p_{\rm T}=7$ GeV/$c$, there is a significant rise in the nuclear modification factor, which reaches $R_{\rm{AA}} \approx0.4$ for $p_{\rm T}>30$ GeV/$c$. In peripheral collisions (70-80%), the suppression is weaker with $R_{\rm{AA}} \approx 0.7$ almost independently of $p_{\rm T}$. The measured nuclear modification factors are compared to other measurements and model calculations.Comment: 17 pages, 4 captioned figures, 2 tables, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/284
