Influence of tree hollow characteristics on the diversity of saproxylic insect guilds in Iberian Mediterranean woodlands

Saproxylic diversity assessment is a major goal for conservation strategies in woodlands and it should consider woodland composition and configuration at site and tree level as key modelling factors. However, in Mediterranean woodlands little is known about the relation with the environmental factors that structure their assemblages, especially those linked to tree hollow microhabitats. We assessed the diversity of Syrphidae (Diptera) and Coleoptera saproxylic guilds that co-occurred in tree hollows located in three different Iberian Mediterranean woodlands in the Cabañeros National Park (Spain). Furthermore, we evaluated how differences in tree hollow microenvironmental variables (understood as the physical and biotic characteristics of a hollow and tree individual) influenced saproxylic guild diversity both within and among woodland sites. We found that woodland sites that provided greater heterogeneity of trees and hollow microhabitats determined higher saproxylic guild diversity. Nevertheless, certain species or even complete guilds can be favoured in woodlands where some hollow microhabitats predominate as a consequence of historical tree management. In general, hollow volume was the main determining factor for saproxylic guild richness and abundance in woodland sites, and large hollow volume was usually related to higher diversity, which highlighted the importance of multi-habitat hollow trees. Moreover, saproxylic guilds also responded to other different microenvironmental variables, which indicated different ecological preferences among guilds. The conservation of saproxylic insects in Iberian Mediterranean areas must be addressed to protect woodland sites that provide high diversity and large numbers of tree hollow microhabitats, and practices to enhance microhabitat heterogeneity should even be encouraged.

«Somos iguales a cualquier otra familia… estamos convencidos de que somos verdaderos padres y de que formamos una auténtica familia». Las familias adoptivas en el catálogo de las nuevas formas familiares

En este artículo abordamos el significado de la familia adoptiva a partir del análisis del discurso de los relatos autobiográficos de madres y padres adoptivos españoles. En un contexto de vacío de cultura adoptiva, las familias adoptivas publican narraciones para ser valoradas como «normales» al tiempo que, en ausencia de modelos de referencia, definen su modelo de familia desdibujando el arquetipo familiar instituido. A partir del método biográfico, aplicamos un doble ejercicio sociológico de (1) deconstrucción ideológica del modelo de familia hegemónico a partir de la (2) construcción del significado que padres y madres adoptivas otorgan a su familia. Las teorías de la familia postmoderna y las teorías feministas postestructuralistas enmarcan el análisis crítico del discurso con perspectiva de género con el que es abordado el estudio de estos singulares documentos personales.

El gènere i l’humor en interaccions didàctiques d’alumnes de secundària

A partir de la articulación de tres ejes o focos de interés: el uso del humor por parte de los adolescentes, las cuestiones de género y las cuestiones que se plantean en torno a una investigación en didáctica de la lengua, este artículo profundiza en la forma y funcionamiento del humor como estrategia para abordar la construcción del espacio intersubjetivo. Esta triple focalización favorece la reflexión en torno a la diferencia de recursos verbales, no verbales y paraverbales que movilizan los interlocutores de cada género a la vez que aporta materiales de discusión novedosos sobre la relación entre el uso del humor y el rol institucional que ocupan los interlocutores, principalmente teniendo en cuenta la imbricación del concepto de posturas enunciativas.

Religiosas y laicas en el franquismo: entre la dictadura y la oposición

En este trabajo se ofrece un estado de la cuestión sobre la evolución de las religiosas y las seglares, de clase media y obreras, de Acción Católica en el franquismo, una dictadura que encontró en la Iglesia a uno de sus principales apoyos. En los años cuarenta y cincuenta participan del control político y moral de las españolas y su presencia pública es destacada. En las décadas siguientes experimentan un profundo cambio hacia un mayor compromiso, todo lo cual conduce a un escenario de tensiones con la dictadura y la jerarquía eclesiástica, y a una crisis que da lugar a la secularización de muchas religiosas y al abandono de Acción Católica de numerosas militantes; en esta etapa de mayor testimonio sin embargo su reconocimiento disminuye.

Discreta regente, la austriaca o Doña Virtudes. Las imágenes de María Cristina de Habsburgo

Más allá del mito de la discreta regente de España, María Cristina de Habsburgo ofrece una imagen poliédrica que puede contribuir a calibrar la importancia política, cultural y social de la representación simbólica de la corona. Las imágenes —oficial, de la oposición y populares— de María Cristina son analizadas desde diversas perspectivas: la consolidación de una monarquía en crisis tras el fallecimiento de Alfonso XII pocos años después de la República, la creación de una identidad nacional todavía no afirmada y la conformación de los estereotipos de género en torno al discurso de la separación de esferas. Imágenes que daban respuestas muchas veces divergentes a las circunstancias que distinguían a Maria Cristina de otros monarcas: era regente y no reina por derecho propio, era extranjera pero ocupaba el trono español y era mujer pero desempeñaba la más alta magistratura del país.

A first approach to earthquake damage estimation in Haiti: advices to minimize the seismic risk

This study is in the frame of the cooperative line that several Spanish Universities and other foreign partners started with the Haitian government in 2010. According to our studies (Benito et al. in An evaluation of seismic hazard in La Hispaniola, after the 2010 Haiti earthquake, 33rd General Assembly of the European Seismological Commission, Moscow, Russia, 2012) and recent scientific literature, the earthquake hazard in Haiti remains high (Calais et al. in Nat Geosci 3:794–799, 2010). In view of this, we wonder whether the country is currently ready to face another earthquake. In this sense, we estimated several damage scenarios in Port-au-Prince and Cap-Haitien associated to realistic possible major earthquakes. Our findings show that almost 50 % of the building stock of both cities would result uninhabitable due to structural damage. Around 80 % of the buildings in both cities have reinforced concrete structure with concrete block infill; however, the presence of masonry buildings becomes significant (between 25 and 45 % of the reinforced concrete buildings) in rural areas and informal settlements on the outskirts, where the estimated damage is higher. The influence of the soil effect on the damage spatial distribution is evident in both cities. We have found that the percentage of uninhabitable buildings in soft soil areas may be double the percentage obtained in nearby districts located in hard soil. These results reveal that a new seismic catastrophe of similar or even greater consequences than the 2010 Haiti earthquake might happen if the earthquake resilience is not improved in the country. Nowadays, the design of prevention actions and mitigation policies is the best instrument the society has to face seismic risk. In this sense, the results of this research might contribute to define measures oriented to earthquake risk reduction in Haiti, which should be a real priority for national and international institutions.

Las ayudas estatales para la reestructuración de la siderurgia española en perspectiva europea (1975-1988)

El objetivo de este artículo es realizar una comparación cuantitativa de las ayudas públicas destinadas a los procesos de reestructuración de la siderurgia en España y en los países de la CECA en el período 1975-1988. Las fuentes utilizadas corresponden tanto a documentación de archivo como a publicaciones periódicas de diversas instituciones: empresas españolas, patronal siderúrgica (Unesid), organismos públicos españoles y de la CEE e informes de la Comisión Europea. El trabajo demuestra que la principal diferencia entre la políticas siderúrgicas española y comunitaria estribó no tanto en el montante de las ayudas públicas destinadas al proceso de reestructuración como en el uso que se hizo de las mismas. Así, mientras en la CEE las ayudas públicas estuvieron condicionadas a la eliminación de los excedentes de capacidad productiva, en España no se realizó ningún ajuste en este sentido hasta nuestra integración en la Comunidad en 1986.

Effect of economic recession on psychosocial working conditions by workers' nationality

Background: Several publications have documented the effects of economic recessions on health. However, little is known about how economic recessions influence working conditions, especially among vulnerable workers. Objective: To explore the effects of 2008 economic crisis on the prevalence of adverse psychosocial working conditions among Spanish and foreign national workers. Methods: Data come from the 2007 and 2011 Spanish Working Conditions Surveys. Survey year, sociodemographic, and occupational information were independent variables and psychosocial factors exposures were dependent variables. Analyses were stratified by nationality (Spanish versus foreign). Prevalence and adjusted prevalence ratios (aPRs) of psychological job demands, job control, job social support, physical demands and perceived job insecurity were estimated using Poisson regression. Results: The Spanish population had higher risk of psychological and physical job demand (aPR = 1.07, 95% CI = [1.04–1.10] and aPR = 1.05, 95% CI = [1.01–1.09], respectively) in 2011 compared to 2007. Among both Spanish and foreign national workers, greater aPR were found for job loss in 2011 compared to 2007 (aPR = 2.47, 95% CI = [2.34–2.60]; aPR = 2.44, 95% CI = [2.15–2.77], respectively). Conclusion: The 2008 economic crisis was associated with a significant increase in physical demands in Spanish workers and increased job insecurity for both Spanish and foreign workers.

A semantic framework for textual data enrichment

In this work we present a semantic framework suitable of being used as support tool for recommender systems. Our purpose is to use the semantic information provided by a set of integrated resources to enrich texts by conducting different NLP tasks: WSD, domain classification, semantic similarities and sentiment analysis. After obtaining the textual semantic enrichment we would be able to recommend similar content or even to rate texts according to different dimensions. First of all, we describe the main characteristics of the semantic integrated resources with an exhaustive evaluation. Next, we demonstrate the usefulness of our resource in different NLP tasks and campaigns. Moreover, we present a combination of different NLP approaches that provide enough knowledge for being used as support tool for recommender systems. Finally, we illustrate a case of study with information related to movies and TV series to demonstrate that our framework works properly.

Visual perception for the 3D recognition of geometric pieces in robotic manipulation

During grasping and intelligent robotic manipulation tasks, the camera position relative to the scene changes dramatically because the robot is moving to adapt its path and correctly grasp objects. This is because the camera is mounted at the robot effector. For this reason, in this type of environment, a visual recognition system must be implemented to recognize and “automatically and autonomously” obtain the positions of objects in the scene. Furthermore, in industrial environments, all objects that are manipulated by robots are made of the same material and cannot be differentiated by features such as texture or color. In this work, first, a study and analysis of 3D recognition descriptors has been completed for application in these environments. Second, a visual recognition system designed from specific distributed client-server architecture has been proposed to be applied in the recognition process of industrial objects without these appearance features. Our system has been implemented to overcome problems of recognition when the objects can only be recognized by geometric shape and the simplicity of shapes could create ambiguity. Finally, some real tests are performed and illustrated to verify the satisfactory performance of the proposed system.

3D Visual Data-Driven Spatiotemporal Deformations for Non-Rigid Object Grasping Using Robot Hands

Sensing techniques are important for solving problems of uncertainty inherent to intelligent grasping tasks. The main goal here is to present a visual sensing system based on range imaging technology for robot manipulation of non-rigid objects. Our proposal provides a suitable visual perception system of complex grasping tasks to support a robot controller when other sensor systems, such as tactile and force, are not able to obtain useful data relevant to the grasping manipulation task. In particular, a new visual approach based on RGBD data was implemented to help a robot controller carry out intelligent manipulation tasks with flexible objects. The proposed method supervises the interaction between the grasped object and the robot hand in order to avoid poor contact between the fingertips and an object when there is neither force nor pressure data. This new approach is also used to measure changes to the shape of an object’s surfaces and so allows us to find deformations caused by inappropriate pressure being applied by the hand’s fingers. Test was carried out for grasping tasks involving several flexible household objects with a multi-fingered robot hand working in real time. Our approach generates pulses from the deformation detection method and sends an event message to the robot controller when surface deformation is detected. In comparison with other methods, the obtained results reveal that our visual pipeline does not use deformations models of objects and materials, as well as the approach works well both planar and 3D household objects in real time. In addition, our method does not depend on the pose of the robot hand because the location of the reference system is computed from a recognition process of a pattern located place at the robot forearm. The presented experiments demonstrate that the proposed method accomplishes a good monitoring of grasping task with several objects and different grasping configurations in indoor environments.

La localización de la clase creativa en ciudades turísticas. Un análisis a escala local del sistema urbano Mediterráneo español

La tendencia a la concentración de flujos económicos y humanos en las principales aglomeraciones ha generado unos polos de atracción global en detrimento de las opciones de desarrollo del resto de territorios. Sin embargo la recomposición territorial está siendo más compleja y afecta también al territorio no metropolitano. La introducción de elementos de creatividad en las economías urbanas es un ejemplo de la relativa dispersión territorial de nuevas actividades productivas. La localización de actividades económicas creativas ha sido analizada para el caso de ciudades medias, periferias urbanas y espacios rurales, pero no para el de ciudades turísticas. El objetivo del trabajo es analizar, a escala local y partiendo del cálculo de un índice sintético de creatividad, el comportamiento de dicho índice y en qué medida la clase creativa se localiza en los destinos turísticos del mediterráneo español y las Islas Canarias en comparación con otros tipos de municipios y entre municipios turísticos según su grado de especialización. Los resultados obtenidos permiten formular la hipótesis sobre cómo contribuyen los espacios turísticos a la reorganización productiva del territorio y valorar sus posibilidades de competitividad basadas en la mejora de la tolerancia, la innovación y el emprendimiento, proporcionando oportunidades de desarrollo más integrales y diversificadas en el momento de crisis actual.

Improving drug discovery using a neural networks based parallel scoring function

Virtual Screening (VS) methods can considerably aid clinical research, predicting how ligands interact with drug targets. Most VS methods suppose a unique binding site for the target, but it has been demonstrated that diverse ligands interact with unrelated parts of the target and many VS methods do not take into account this relevant fact. This problem is circumvented by a novel VS methodology named BINDSURF that scans the whole protein surface to find new hotspots, where ligands might potentially interact with, and which is implemented in massively parallel Graphics Processing Units, allowing fast processing of large ligand databases. BINDSURF can thus be used in drug discovery, drug design, drug repurposing and therefore helps considerably in clinical research. However, the accuracy of most VS methods is constrained by limitations in the scoring function that describes biomolecular interactions, and even nowadays these uncertainties are not completely understood. In order to solve this problem, we propose a novel approach where neural networks are trained with databases of known active (drugs) and inactive compounds, and later used to improve VS predictions.

El principio de igualdad y no discriminación en relación con la pensión de viudedad y el «matrimonio gitano»

El punto de partida de nuestro estudio se sitúa en el polémico y discutido asunto resuelto por la sentencia del Tribunal Europeo de Derechos Humanos de 8 de diciembre de 2009, Caso Muñoz Díaz c. España, donde se condena al Estado español por denegar la pensión de viudedad a una ciudadana casada exclusivamente por el rito matrimonial gitano. Al hilo de esta resolución analizaremos, entre otras cuestiones, las diversas formas matrimoniales a las que nuestro legislador otorga efectos civiles, la incidencia de dichas disposiciones en el principio de igualdad y no discriminación consagrado en el artículo 14 de la Constitución y en el artículo 14 del Convenio Europeo de Derechos Humanos, y la posible vulneración de dicho principio en el marco de las prestaciones sociales reguladas en la Ley General de la Seguridad Social, recientemente reformada.
