La Comunidad geospacial y el acceso a datos oceanográficos

Nowadays, Oceanographic and Geospatial communities are closely related worlds. The problem is that they follow parallel paths in data storage, distributions, modelling and data analyzing. This situation produces different data model implementations for the same features. While Geospatial information systems have 2 or 3 dimensions, the Oceanographic models uses multidimensional parameters like temperature, salinity, streams, ocean colour... This implies significant differences between data models of both communities, and leads to difficulties in dataset analysis for both sciences. These troubles affect directly to the Mediterranean Institute for Advanced Studies ( IMEDEA (CSIC-UIB)). Researchers from this Institute perform intensive processing with data from oceanographic facilities like CTDs, moorings, gliders… and geospatial data collected related to the integrated management of coastal zones. In this paper, we present an approach solution based on THREDDS (Thematic Real-time Environmental Distributed Data Services). THREDDS allows data access through the standard geospatial data protocol Web Coverage Service, inside the European project (European Coastal Sea Operational Observing and Forecasting system). The goal of ECOOP is to consolidate, integrate and further develop existing European coastal and regional seas operational observing and forecasting systems into an integrated pan- European system targeted at detecting environmental and climate changes

Utilización de software libre para el análisis de la evolución de usos del suelo en la cuenca del Segura mediante teledetección

En este trabajo se describe la utilización de herramientas de software libre, básicamente GRASS y R, para obtener una serie de mapas de coberturas del suelo (1976-2006) a partir de imágenes de satélite Landsat MSS y Landsat TM. Se trata de un proyecto concedido a un año, por lo que se requería una metodología que permitiera realizar el análisis de forma rápida y sencilla, aún tratando de aplicar técnicas de clasificación avanzadas. Dada la complejidad del trabajo y la premura de tiempo, se ha tratado de automatizar gran parte del trabajo mediante diversos scripts con BASH y R. (...)

Acogimiento en familia extensa: un estudio desde la perspectiva de los acogedores, de los niños y niñas acogidos y de los profesionales que intervienen. = Kinship foster care: a study from the perspective of the caregivers, the children and the child welfare workers

Desde hace aproximadamente dos décadas, en la mayoría de los países occidentales, los acogimientos en familia extensa han entrado a formar parte de los sistemas de protección infantil, siguiendo una evolución creciente en cuanto a número y peso especifico como recurso de acogimiento. Las investigaciones sobre este fenómeno son aún recientes y escasas como también lo son los programas dirigidos a esta población. En el presente artículo presentamos los resultados de un estudio descriptivo sobre los acogimientos en familia extensa en la ciudad de Barcelona, donde se recogen datos de los principales agentes implicados en este fenómeno. Desde la perspectiva de los estudios de la calidad de vida se analizan las percepciones, evaluaciones, y satisfacción expresada, por parte de los acogedores, los niños/as acogidos y los profesionales de los Equipos de Atención a la Infancia y Adolescencia (EAIA) que se encargan del estudio y seguimiento de estos acogimientos. La investigación presenta unos resultados acordes con los estudios que actualmente se realizan en este ámbito y sienta las bases para el despliegue futuro de programas dirigidos a los acogimientos en familia extensa

Revisión documental en las bases de datos educativas : un análisis de la documentación disponible sobre evaluación de la transferencia de los aprendizajes.

Las bases de datos educativas son una fuente de información especializada para la investigación científica. Juegan un papel imprescindible para la conexión de producciones, novedades y resultados, y la difusión de los mismos en todo el mundo. Sin embargo, las bases de datos de mayor alcance y volumen de documentación funcionan con un acceso restringido a usuarios y/o organizaciones que pagan una cuota de suscripción. Asimismo, no todas las bases de datos cuentan con sistemas para depurar la información objeto de búsqueda. Cabe añadir, que algunas áreas documentales tienen una presencia muy limitada en las mismas, como es el caso de la documentación sobre evaluación de la transferencia de los aprendizajes; el objetivo de esta comunicación es presentar el análisis realizado de la documentación disponible sobre esta temática en las principales bases de datos educativas.

"Thematically Analysing Social Network Content During Disasters Through the Lens of the Disaster Management Lifecycle" & "Investigating Similarity Between Privacy Policies of Social Networking Sites as a Precursor for Standardization"

Abstract 1: Social Networks such as Twitter are often used for disseminating and collecting information during natural disasters. The potential for its use in Disaster Management has been acknowledged. However, more nuanced understanding of the communications that take place on social networks are required to more effectively integrate this information into the processes within disaster management. The type and value of information shared should be assessed, determining the benefits and issues, with credibility and reliability as known concerns. Mapping the tweets in relation to the modelled stages of a disaster can be a useful evaluation for determining the benefits/drawbacks of using data from social networks, such as Twitter, in disaster management.A thematic analysis of tweets’ content, language and tone during the UK Storms and Floods 2013/14 was conducted. Manual scripting was used to determine the official sequence of events, and classify the stages of the disaster into the phases of the Disaster Management Lifecycle, to produce a timeline. Twenty- five topics discussed on Twitter emerged, and three key types of tweets, based on the language and tone, were identified. The timeline represents the events of the disaster, according to the Met Office reports, classed into B. Faulkner’s Disaster Management Lifecycle framework. Context is provided when observing the analysed tweets against the timeline. This illustrates a potential basis and benefit for mapping tweets into the Disaster Management Lifecycle phases. Comparing the number of tweets submitted in each month with the timeline, suggests users tweet more as an event heightens and persists. Furthermore, users generally express greater emotion and urgency in their tweets.This paper concludes that the thematic analysis of content on social networks, such as Twitter, can be useful in gaining additional perspectives for disaster management. It demonstrates that mapping tweets into the phases of a Disaster Management Lifecycle model can have benefits in the recovery phase, not just in the response phase, to potentially improve future policies and activities. Abstract2: The current execution of privacy policies, as a mode of communicating information to users, is unsatisfactory. Social networking sites (SNS) exemplify this issue, attracting growing concerns regarding their use of personal data and its effect on user privacy. This demonstrates the need for more informative policies. However, SNS lack the incentives required to improve policies, which is exacerbated by the difficulties of creating a policy that is both concise and compliant. Standardization addresses many of these issues, providing benefits for users and SNS, although it is only possible if policies share attributes which can be standardized. This investigation used thematic analysis and cross- document structure theory, to assess the similarity of attributes between the privacy policies (as available in August 2014), of the six most frequently visited SNS globally. Using the Jaccard similarity coefficient, two types of attribute were measured; the clauses used by SNS and the coverage of forty recommendations made by the UK Information Commissioner’s Office. Analysis showed that whilst similarity in the clauses used was low, similarity in the recommendations covered was high, indicating that SNS use different clauses, but to convey similar information. The analysis also showed that low similarity in the clauses was largely due to differences in semantics, elaboration and functionality between SNS. Therefore, this paper proposes that the policies of SNS already share attributes, indicating the feasibility of standardization and five recommendations are made to begin facilitating this, based on the findings of the investigation.

The Poetics of Game Narratives

In this final week we will look at the tensions between ludology and narratology in games design, in effect how the agency of games has been reconciled with the dramatic requirements (and lack of agency) in narrative. I will argue that there are two broad approaches, the mainstream method of concentrating in the Fabula, and a method pioneered by many indie games of fusing narrative and play. We will look in more detail at what this might mean in terms of thematic cohesion, diegetic choices, and mechanics and metaphor. Finally we look at Spec Ops: The Line, as a rare example of a AAA title that takes this fusion approach. Looking at how the game uses many of the techniques we have explored.
