(Table S1) Original element/Ca data for the OGA and Tahiti corals

[1] Previous studies have demonstrated the potential for the Li content of coral aragonite to record information about environmental conditions, but no detailed study of tropical corals exists. Here we present the Li and Mg to Ca ratios at a bimonthly to monthly resolution over 25 years in two modern Porites corals, the genus most often used for paleoclimate reconstructions in the tropical Indo-Pacific. A strong relationship exists between coral Li/Ca and locally measured SST, indicating that coral Li/Ca can be used to reconstruct tropical SST variations. However, Li/Ca ratios of the skeleton deposited during 1979-1980 do not track local SST well and are anomalously high in places. The Mg/Ca ratios of this interval are also anomalously high, and we suggest Li/Ca can be used to reconstruct tropical SST only when Mg/Ca data are used to carefully screen for relatively rare biological effects. Mg/Li or Li/Mg ratios provide little advantage over Li/Ca ratios, except that the slope of the Li/Mg temperature relationship is more similar between the two corals. The Mg/Li temperature relationship for the coral that experienced a large temperature range is similar to that found for cold water corals and aragonitic benthic foraminifera in previous studies. The comparison with data from other biogenic aragonites suggests the relationship between Li/Mg and water temperature can be described by a single exponential relationship. Despite this hint at an overarching control, it is clear that biological processes strongly influence coral Li/Ca, and more calibration work is required before widely applying the proxy.

La memoria en el proceso creativo de Juan Muñoz = Memory in the creative process of Juan Muñoz

Esta tesis integra un estudio reflexivo sobre la relación de dependencia entre la creación y la memoria a través del análisis de la última obra del escultor Juan Muñoz: Double Bind (Tate Modern, Londres, 2001). Desde esta posición es obligado replantear el análisis de la obra, lo que hace necesario su estudio cubriendo el mayor espectro posible de información accesible más allá de la obra en sí, para aproximarse a la convergencia entre memoria y creación. La perspectiva de análisis propuesta abre camino a nuevas consideraciones so¬bre la relevancia del conocimiento en el desarrollo del proceso creativo. Este análisis no debe tan sólo suponer una aportación al conocimiento del trabajo de Juan Muñoz. Debe también desprenderse de él la innegable participación y necesaria lectura del pasado en el presente. La amnesia de los tiempos pasados impide completar el atlas de imágenes en las que se apoya la creación impidiendo el conocimiento del origen de las fuentes de inspi¬ración y las bases de la creación de una determinada obra. Este hecho limita y distorsiona sus posibles interpretaciones. Pretendo un acercamiento al entendimiento de la forma de mirar y de crear a través del tiempo que es memoria. La memoria tiene un cometido de crucial importancia para la actividad mental y juega un papel fundamental en la conducta y en la creación. La obra es el resultado de la búsqueda de una idea que exprese algo que el creador no puede ex¬presar de otra manera. Es la necesidad de expresar las ideas mediante un lenguaje que se desarrolla en el tiempo y en el espacio, reflejo del ser que responde al pensamiento. Es una forma de experiencia donde subyacen las sendas del pasado y donde se plantea el futuro. Sólo el creador accede a la obra desde dentro, el observador llega a ella desde el exterior y mediante su propia subjetividad. Las obras son formas de experiencia de sus autores, comunicar el mensaje de dicha experiencia supone por tanto interpretar. Persiguiendo la necesidad de saber y entender, pretender explicar el sentido de una cosa implica una apreciación intencionada asociada al entendimiento del intérprete. Las obras son produc¬tos que portan un mensaje y que contienen en su estructura las trazas del tiempo vivido por su creador. Si se quiere adquirir un acercamiento que represente la posición de un autor, será necesario no solo mirar a través de ella, si no introducirse en el contexto de su historia. Mirar hacia atrás, hacia la profundidad del presente para tener conciencia del pensamiento presente y futuro. Recorrer de este modo la instalación Double Bind de Juan Muñoz proporciona una síntesis de sus preocupaciones e intereses a la vez que aporta un conocimiento no necesariamente inmediato, pero relevante y trascendente de la obra, su creador y la historia. ABSTRACT This thesis comprises a reflective study of the dependence relationship between creation and memory through the analysis of the latest work by the sculptor Juan Muñoz: Double Bind (Tate Modern, London, 2001). From this position, it is mandatory to rethink the analysis of the work, making it necessary to cover the widest possible range of information available beyond the work itself, in order to obtain a closer view of the convergence between memory and creation. The proposed analytical approach opens up new considerations on the relevance of knowledge during the development of the creative process. This analysis should not only make a contribution to the knowledge of the work of Juan Muñoz. It should also infer the undeniable involvement and the necessary reading of the past in the present. Amnesia regarding past makes it impossible to complete the atlas of images on which the creation is based, blocking knowledge of the origin of the sources of inspiration and the basis for the creation of a specific work. This fact limits and distorts its possible interpretations. My intention is an approach to how to understand memory as the way of looking and creating over time. Memory has a crucial role to mental activity and plays a key role in behaviour and creation. The work is the result of finding an idea that expresses something that the creator can not express otherwise. It is the need to express ideas by means of a language that develops throughout time and space, a reflection of the being that responds to the thought. It is a way of experience underlying the paths of the past and where the future is set out. Only the creator can access the work from the inside. The observer sees it from the outside and in accordance with his/her own subjectivity. The works form a part of the experience of their authors, thus implying the interpretation of the message of their experience being passed on. The pursuit of knowledge and understanding, and trying to explain the meaning of something implies a deliberate appreciation associated with the understanding of the interpreter. The works are products bearing a message and containing in their structure traces of the time lived by their creator. If one wants to come close to what the author’s posture represents, it will not only be necessary to penetrate it, but also to introduce oneself into the context of its history. Take a look back, towards the depth of the present in order to become aware of present and future thinking. To go across the installation of Double Bind by Juan Muñoz in this way offers a synthesis of his concerns and interests while also providing a not necessarily immediate knowledge, but one which is relevant and important to the work, its creator and history.

Will austerity cuts dismantle the Spanish healthcare system?

In the face of austerity, a series of disconnected “reforms” could, without corrective measures, lead to the effective dismantling of large parts of the Spanish healthcare system, with potentially detrimental effects on health. Helena Legido-Quigley and colleagues explain.

3D visual sensing of human hand for remote operation of a robotic hand

New low cost sensors and open free libraries for 3D image processing are making important advances in robot vision applications possible, such as three-dimensional object recognition, semantic mapping, navigation and localization of robots, human detection and/or gesture recognition for human-machine interaction. In this paper, a novel method for recognizing and tracking the fingers of a human hand is presented. This method is based on point clouds from range images captured by a RGBD sensor. It works in real time and it does not require visual marks, camera calibration or previous knowledge of the environment. Moreover, it works successfully even when multiple objects appear in the scene or when the ambient light is changed. Furthermore, this method was designed to develop a human interface to control domestic or industrial devices, remotely. In this paper, the method was tested by operating a robotic hand. Firstly, the human hand was recognized and the fingers were detected. Secondly, the movement of the fingers was analysed and mapped to be imitated by a robotic hand.

Spontaneous Abortions and Shift Work in a Cohort of Nurses in Norway

Background: An association between spontaneous abortions and shift work has been suggested, but present research results are conflicting. The aim of the study is to evaluate the relationship between spontaneous abortions among nurses, shift schedules, and nights worked. Methods: This is a longitudinal study where we identified 914 females from a cohort of nurses in Norway who had worked the same type of shift schedule 2008-2010; either permanent day shift, three-shift rotation or permanent night shift. Information on age, work and life-style factors, as well as spontaneous abortions during lifetime and the past three years (2008-2010) was obtained by annual questionnaires. Results: A higher prevalence of experienced spontaneous abortions before study start (2008) was found among nurses working permanent night shift compared to other nurses. In a linear regression analysis, a risk of 1.3 was found for experienced spontaneous abortions before study start among permanent night shift nurses, with day shift as reference, when adjusting for age, smoking, caffeine and job strain, but the finding was not statistical significant (95 per cent confidence interval 0.8-2.1). Permanent night shift workers had a risk of 1.5 experiencing spontaneous abortions in 2008-2010 compared to day shift nurses, although not statistical significant (95 per cent confidence interval 0.7-3.5). The number of night shifts the past three years was not associated with experiencing spontaneous abortions 2008-2010, but associated with a reduced risk of experiencing spontaneous abortions during lifetime. The results must be interpreted in the light of a possible selection bias; both selections into the occupation of nursing and into the different shift types of the more healthy persons may have occurred in this population. Conclusion: No significant increased risk of spontaneous abortion among permanent night shift nurses compared to day-time nurses was found in this study, and no association was found between spontaneous abortions and the number of worked night shifts.

Hacer… hablar; hablar… tal vez habitar. Apuntes sobre lo dicho y hecho por Adolf Loos (1870-1933)

Ornamento y delito y Arquitectura, los dos artículos que sin duda han contribuido a difundir el ideario y a sustentar la celebridad del arquitecto Adolf Loos (1870-1933), proceden de sendas conferencias. Su origen, por consiguiente, es de naturaleza oral. Y la polémica desencadenada a raíz de ellos los convierte, en su época y para la Historia, en auténticos oráculos, cuyo sentido sus transcripciones, tanto francesa como alemana, inevitablemente en parte desvirtúan. Solo cotejando lo dicho por el maestro, y luego escrito y publicado, con su obra edificada podemos restituir el sentido original de su pensamiento. Esta es la hipótesis sobre la que discurrimos. A sus palabras y obras habrá que sumar la atención que el arquitecto y periodista, que así se confiesa, confiere a los oficios y a los materiales que los sustentan, en la línea de pensamiento de Gottfried Semper, como fundamento del diseño. Es pues a la luz de su concurrencia a la obra de arquitectura, y de ésta al espacio de habitación, y no de otros documentos gráficos y fotográficos, como ha de valorarse lo dicho y escrito por Loos, si nos atenemos a sus propias recomendaciones. Lo dicho se ilumina con lo hecho. Y lo hecho se autoriza por lo habitado.

Coupled Biomechanical Response of the Cornea Assessed by Non-Contact Tonometry. A Simulation Study

The mechanical response of the cornea subjected to a non-contact air-jet tonometry diagnostic test represents an interplay between its geometry, the corneal material behavior and the loading. The objective is to study this interplay to better understand and interpret the results obtained with a non-contact tonometry test. A patient-specific finite element model of a healthy eye, accounting for the load free configuration, was used. The corneal tissue was modeled as an anisotropic hyperelastic material with two preferential directions. Three different sets of parameters within the human experimental range obtained from inflation tests were considered. The influence of the IOP was studied by considering four pressure levels (10–28 mmHg) whereas the influence of corneal thickness was studied by inducing a uniform variation (300–600 microns). A Computer Fluid Dynamics (CFD) air-jet simulation determined pressure loading exerted on the anterior corneal surface. The maximum apex displacement showed a linear variation with IOP for all materials examined. On the contrary, the maximum apex displacement followed a cubic relation with corneal thickness. In addition, a significant sensitivity of the apical displacement to the corneal stiffness was also obtained. Explanation to this behavior was found in the fact that the cornea experiences bending when subjected to an air-puff loading, causing the anterior surface to work in compression whereas the posterior surface works in tension. Hence, collagen fibers located at the anterior surface do not contribute to load bearing. Non-contact tonometry devices give useful information that could be misleading since the corneal deformation is the result of the interaction between the mechanical properties, IOP, and geometry. Therefore, a non-contact tonometry test is not sufficient to evaluate their individual contribution and a complete in-vivo characterization would require more than one test to independently determine the membrane and bending corneal behavior.

Design of Activated Carbon/Activated Carbon Asymmetric Capacitors

Supercapacitors are energy storage devices that offer a high power density and a low energy density in comparison with batteries. Their limited energy density can be overcome by using asymmetric configuration in mass electrodes, where each electrode works within their maximum available potential window, rendering the maximum voltage output of the system. Such asymmetric capacitors are optimized using the capacitance and the potential stability limits of the electrodes, with the reliability of the design largely depending on the accuracy and the approach taken for the electrochemical characterization. Therefore, the performance could be lower than expected and even the system could break down, if a well thought out procedure is not followed. In this work, a procedure for the development of asymmetric supercapacitors based on activated carbons is detailed. Three activated carbon materials with different textural properties and surface chemistry have been systematically characterized in neutral aqueous electrolyte. The asymmetric configuration of the masses of both electrodes in the supercapacitor has allowed to cover a higher potential window, resulting in an increase of the energy density of the three devices studied when compared with the symmetric systems, and an improved cycle life.

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.

Características de ecossistema e sustentabilidade: estudo sobre a vegetação original e remanescente da bacia hidrográfica do Rio Canoas

Com o objetivo de comparar em termos de paisagem, a vegetação florestal nativa com os fragmentos da vegetação remanescente na bacia hidrográfica do Rio Canoas, situada na divisa dos Estados de São Paulo (à Nordeste) e Minas Gerais (à Centro-Oeste), busca-se dar subsídios aos atores locais para trabalhar políticas públicas com vistas à sustentabilidade do uso dos recursos naturais na região. Foram mapeados sete tipos de vegetação, com destaque para o cerrado e a floresta estacional semidecidual. O método do estudo é exploratório, realizado em fontes secundárias, pesquisa bibliográfica e documental, baseado no estudo de mapas e suas simulações, dados do IBGE, Embrapa, Ministério do Meio Ambiente e trabalhos de autores, como: Cogo (1987), Coutinho (2000) e Bozini (2005). Observou-se que a bacia hidrográfica objeto em estudo é degradada historicamente pelos diversos usos e ocupações do solo e sua maior parte ainda está sujeita à um elevado nível de perturbação, seja pela pecuária, ou mesmo pelas plantações de laranja, milho, eucalipto, cana-de-açúcar e, principalmente, pela cultura do café.
