Perspectivas de la filosofía analítica en el siglo XXI

A relatively close account of the evolution of analytical philosophy shows that never enjoyed an unique methodology nor a common set of theses. In particular, if we understand that by ‘analytical philosophy’ we refer to a wider philosophical movement than the ‘ordinary language philosophy’, such lack of methodological or substantial coherence is even more evident. Then, it can be asked whether a conceptual description of analytical philosophy at the beginnings of XXI century is possible. As it is proposed, such description is only feasible under an axiological basis, that is, under the commitment with a set of scholar values that give a minimal consistency to philosophical analysis such it is practised nowadays. The nature of those values can be included, generally speaking, in the realm of the epistemological, but what is concretely contended is that it is mandatory to pay attention to its discursive and argumentative nature. This shift of focus allows to surpass the virtues and flaws of analytical philosophy in the 20 nth century and facilitates the re evaluation of its function in the 21 nth one

PadChest: A large chest x-ray image dataset with multi-label annotated reports

We present a labeled large-scale, high resolution chest x-ray dataset for the automated exploration of medical images along with their associated reports. This dataset includes more than 160,000 images obtained from 67,000 patients that were interpreted and reported by radiologists at Hospital San Juan Hospital (Spain) from 2009 to 2017, covering six different position views and additional information on image acquisition and patient demography. The reports were labeled with 174 different radiographic findings, 19 differential diagnoses and 104 anatomic locations organized as a hierarchical taxonomy and mapped onto standard Unified Medical Language System (UMLS) terminology. Of these reports, 27% were manually annotated by trained physicians and the remaining set was labeled using a supervised method based on a recurrent neural network with attention mechanisms. The labels generated were then validated in an independent test set achieving a 0.93 Micro-F1 score. To the best of our knowledge, this is one of the largest public chest x-ray database suitable for training supervised models concerning radiographs, and the first to contain radiographic reports in Spanish. The PadChest dataset can be downloaded from http://bimcv.cipf.es/bimcv-projects/padchest/

Ecologías del Aprendizaje en la Educación Social: la Tecnobiografía

La expansión de los medios de comunicación y todo lo que nos permiten hacer está significando un cambio en el planteamiento de la educación actual. Las nuevas tecnologías nos están permitiendo modificar la realidad en la que vivimos haciendo que cada vez sean más las opciones de las que disponemos para trabajar la educación. Han surgido numerosas transformaciones de los espacios de aprendizaje donde la educación expandida está tomando una especial relevancia. Los aprendizajes invisibles se dan cada vez en contextos más variados y nos permiten expandir la educación yendo más allá de la educación formal sumándole el uso de las nuevas tecnologías. Estos nuevos modelos nos están permitiendo “repensar” la educación incorporando nuevos procesos de aprendizaje modificando la forma de aprender a aprender pues es una realidad que vivimos en una sociedad de conocimiento donde éste es cada vez más variable.Grado en Educación Socia

Using nodal coordinates as variables for the dimensional synthesis of mechanisms

The method of the lower deformation energy has been successfully used for the synthesis of mechanisms for quite a while. It has shown to be a versatile, yet powerful method for assisting in the design of mechanisms. Until now, most of the implementations of this method used the dimensions of the mechanism as the synthesis variables, which has some advantages and some drawbacks. For example, the assembly configuration is not taken into account in the optimization process, and this means that the same initial configuration is used when computing the deformed positions in each synthesis point. This translates into a reduction of the total search space. A possible solution to this problem is the use of a set of initial coordinates as variables for the synthesis, which has been successfully applied to other methods. This also has some additional advantages, such as the fact that any generated mechanism can be assembled. Another advantage is that the fixed joint locations are also included in the optimization at no additional cost. But the change from dimensions to initial coordinates means a reformulation of the optimization problem when using derivatives if one wants them to be analytically derived. This paper tackles this reformulation, along with a proper comparison of the use of both alternatives using sequential quadratic programming methods. In order to do so, some examples are developed and studied.The authors wish to thank the Spanish Ministry of Economy and Competitiveness for its support through Grant DPI2013-46329-P and DPI2016-80372-R.

España y la promoción de la gobernanza en Argelia

Este artículo expone las razones por las cuales España, que disfruta de un régimen democrático consolidado, sigue promoviendo con tanta debilidad y ambigüedad la democracia e incluso la buena gobernanza en ciertos países. Acontecimientos recientes, como el impacto del terrorismo internacional, han hecho aún más urgente la asistencia democrática a los países vecinos del Magreb. El propio concepto de gobernanza, a pesar de sus limitaciones y sesgos iniciales, permitiría hacer una promoción no intrusiva de la democracia. Sin embargo, los actores de la política exterior española y de la cooperación al desarrollo, como ilustra perfectamente el caso de Argelia, han sido claramente reticentes a comprometerse en este curso de acción. La obvia dependencia energética española de Argelia, hecho que se suele aducir como la principal razón explicativa, es cuestionada basándose no sólo en la evidencia de la acción española en otros países y regiones, como Túnez o América Latina, sino también en un análisis de los discursos e instrumentos de la política exterior española. Como explicación alternativa, se sugiere que prácticas largamente utilizadas en la política exterior “árabe” de España, la reforma pendiente del servicio exterior, la europeización de la acción exterior y el “síndrome de segundo jugador”, después de Francia, dan mejor cuenta de la ambigüedad española y de su lento abandono de las políticas favorables al statu quo

Las alianzas en el inicio del mercado del cable en España : un enfoque institucional

El presente trabajo analiza las alianzas en el mercado del cable español en el momento inmediatamente anterior a la convocatoria de los concursos a las diferentes demarcaciones (principios de 1997). Partiendo de que uno de los objetivos de la regulación es contribuir a la estabilidad del mercado y después de mostrar algunos de los principales motivos para la alianza, hemos dividido los operadores de cable en tres grupos estratégicos: modestos, intermedios y grandes operadores. Entre las características de este último grupo destacan una mayoría de socios financieros y una reducida presencia de empresas extranjeras. Este artículo abre el camino a posteriores análisisThis article discusses alliances in cable at the first moment in the development of this business. The main objective of regulation is to stabilize new markets. Cable operators are divided into three groups: small, medium-sized and large operators. The last group is very interesting because of the prevalence of banks and electric companies as shareholders. Aside from these entities, there are a few foreign stockholders in Spanish cable. These are the main characteristics of large operators. This work opens avenues to future research

Synopsis of Dorstenia (Moraceae) in Rio Grande do Sul, Southern Brazil

A taxonomic synopsis of Dorstenia (Moraceae) in Rio Grande do Sul (RS), Southern Brazil, is presented. Three species were recorded: D. brasiliensis, D. carautae, a new record for the state of RS, and D. tenuis. All species are described and illustrated through detailed photos of living specimens. A taxonomic key to separate the species, as well as details on distribution, overall phenology, habitat, conservation status and ecology are presented
