¿ Una imagen o mil palabras? La competencia comunicativa lingüística audiovisual encuadrada a través del cine
El documento de trabajo contiene descripción y documentación de cómo trabajar películas en el aula de lengua y literatura en la etapa de educación primaria y secundaria.
El cine es la maquinaria más formidable de desplegar emociones y conectarnos con el mundo, con las personas, con la vida. Desde que nació la “pantalla fascinadora” a finales del siglo XIX, el cine ha ido evolucionando y transformándose adoptando distintas formas. Pero a pesar de ello, su fuerza comunicativa y motivadora sigue siendo fascinante, desbordante, mágica.
Cada vez son más son compartidas las grandes contribuciones pedagógicas del uso del cine en clase para promover conocimientos interdisciplinarios, contextualizar contenidos de enseñanza, favorecer la identificación sujeto-objeto, recuperar el carácter documental que el cine posee desde sus inicios, ahondar en el enfoque comunicativo que proporciona para el aprendizaje de lenguas extranjeras, el acercamiento a la literatura, establecer y reconocer relaciones intertextuales con otros textos y para educar en el goce artístico-lúdico. A todas estas contribuciones pedagógicas tenemos que añadir que en la pantalla conviven varios lenguajes: el verbal, el no verbal y el audiovisual, fundamentales para el desarrollo del intelecto humano. La multimodalidad es inherente al lenguaje cinematográfico, y tenemos que saber leer e interpretar los mensajes en distintos códigos. Desde Cinescola defendemos la necesidad de desarrollar la alfabetización múltiple (Unión Europea, 2012), que tanto engloba las competencias de lectura como de escritura para la comprensión, utilización y evaluación crítica de diferentes formas de información y textos. En esta línea, presentaremos propuestas didácticas experimentadas para educación primaria y secundaria que fomentan la comprensión tanto del lenguaje verbal como el audiovisual. Sustentadas en el proceso de recepción lectora y sus distintas fases, se apoyan en dos estrategias clave para la fase de comprensión e interpretación: la estrategia de comparación de textos breves (cinematográfico, literario, narrativo, ilustrado, etc.) y la estrategia de traducción de textos (por ejemplo, explicar con imágenes un fragmento escrito, narrar de forma oral o escrita una secuencia fílmica, etc.). Con ello, contribuimos de forma clara al desarrollo de la competencia comunicativa lingüística y la audiovisual a partir del cine. En nuestra pantalla proyectaremos secuencias de las películas Smoke (Wang, 1995); Akeelah and the Bee (Doug Atchinson, 2006); El pequeño vampiro (Edel, 2000); Mis tardes con Margueritte (Becker, 2010); junto con la novela El cine de Claudia (Breu, 2014) para aprender cine a través de una novela.El document de treball és el material que s'ha preparat per una conferència encarregada pel Getxolinguae, de Kalitatea Hezkuntzan
Virtual laboratories on energy management systems: the Hybrid Electric Vehicle case
Due to environment and social needs, energy management is becoming a key easy which must be transversely introduced to engineering students. Unfortunately most of this topics are difficult to analyze in traditional laboratories, this paper presents a virtual laboratory on Hybrid Electrical Vehicles specially designed to illustrate the power flow and the energy management algorithms involved in this type of device. The paper describes the models behind the interactive virtual laboratory, the different configurations which can be taken into account and the implementation technology.Peer ReviewedPostprint (published version
Post-handover housing defects: sources and origins
In Spain, the high levels of inexperienced workers and the long chains of subcontracting contribute to the poor quality of dwellings.
Althoughthe
Ley reguladora de la subcontratación en el Sector de la Construcción
(subcontracting law) has established quality measures, the
number of customer complaints is still increasing. In this paper, a total of 2,351 posthandover defects derived from four Spanish builders and
seven residential developments are classi
fi
ed according to their source and origin. The research reveals that the most common defects identi
fi
ed
by customers at posthandover were derived from bad workmanship and were related to construction errors and omissions. Typical defects were

defects were caused by poor design because they are mainly detected and resolved during construction or become apparent after some years of
use. This study demonstrates the negative impact of redoing defective work during the

programs for workers, specialization of subcontractors, and tightening external controls prior to handover.Postprint (author's final draft
Detection of gamma rays of likely jet origin in Cygnus X-1
Aims: Probe the high-energy (60 MeV) emission from the black hole X-ray
binary system, Cygnus X-1, and investigate its origin. Methods: We analysed 7.5
yr of data by Fermi/LAT with the latest PASS8 software version. Results: We
report the detection of a signal at 8 statistical significance
spatially coincident with Cygnus X-1 and a luminosity above 60 MeV of
5.510 erg s. The signal is correlated with the hard X-ray
flux: the source is observed at high energies only during the hard X-ray
spectral state, when the source is known to display persistent, relativistic
radio emitting jets. The energy spectrum, extending up to 20 GeV without
any sign of spectral break, is well fitted by a power-law function with a
photon index of 2.30.2. There is a hint of orbital flux variability, with
high-energy emission mostly coming around the superior conjunction.
Conclusions: We detected GeV emission from Cygnus X-1 and probed that the
emission is most likely associated with the relativistic jets. The evidence of
flux orbital variability points to the anisotropic inverse Compton on stellar
photons as the mechanism at work, thus constraining the emission region to a
distance cm from the black hole.Comment: accepted A\&A (9 pages and 7 figures
Educate the way of looking for multiple literacy
El elevado consumo de pantallas al cual la ciudadanía estamos expuestos diariamente no garantiza que, por el
simple hecho de consumir, ingerir información e imágenes, podamos realizar una literacidad crítica (Cassany,
2011) de la multiplicidad mensajes y códigos que corren por ellas. Cada vez más, la línea divisoria entre la realidad
virtual y la experiencia vital (Aguaded, 2012) es más confusa. Desde un punto de vista educativo, la educación
mediática (Ambròs y Breu, 2011) todavía no es una realidad, sino que falta mucho camino por recorrer y alcanzar la
alfabetización múltiple (UNESCO, 2012). Engullidos por la pantalla global (Lipovetsky y Serroy, 2009), reclamamos
la importancia de la educación cinematográfica para aprender la sintaxis y el lenguaje audiovisual, para dotar a los
discentes de claves para comprender mejor la historia, la sociedad, la vida. El portal educativo Cinescola ofrece más
de cien propuestas didácticas gratuitas sobre películas en su décimo aniversario. Siguiendo su método de análisis,
mostramos una secuencia de lectura de la película Akeelah and the Bee (Atchinson, 2006), probada en distintos
niveles educativos.The high consumption of screens to which the citizenship is exposed every day does not guarantee that, for the
simple fact of consuming, of consuming information and images, we could fulfil a critical literacidad (Cassany,
2011) of the multiplicity messages and codes that run for them. Increasingly, the dividing line between the virtual
reality and the vital experience (Aguaded, 2012) is more confused. From an educational point of view, the media
education (Ambròs and Breu, 2011) still is not a reality, but a lot of way is absent for crossing and to reach the multiple
literacy (UNESCO, 2012). Devoured by the global screen (Lipovetsky and Serroy, 2009), we claim the importance
of the cinematographic education to learn the syntax and the audio-visual language, to endow the discentes of keys
to understand better the history, the company, the life. The educational portal Cinescola offers more than hundred
didactic free offers on movies in his tenth anniversary. Following his method of analysis, we show a sequence of
reading of the movie Akeelah and the Bee (Atchinson, 2006), proved in different educational levels
Correspondence matching in unorganized 3D point clouds using Convolutional Neural Networks
This document presents a novel method based in Convolutional Neural Networks (CNN) to obtain correspondence matchings between sets of keypoints of several unorganized 3D point cloud captures, independently of the sensor used. The proposed technique extends a state-of-the-art method for correspondence matching in standard 2D images to sets of unorganized 3D point clouds. The strategy consists in projecting the 3D neighborhood of the keypoint onto an RGBD patch, and the classi cation of patch pairs using CNNs. The objective evaluation of the proposed 3D point matching based in CNNs outperforms existing 3D feature descriptors, especially when intensity or color data is available.Peer ReviewedPostprint (author's final draft
Influence of pH and a porphyrin ligand on the stability of a G-quadruplex structure within a duplex segment near the promoter region of the SMARCA4 gene
In a previous work, the formation of G-quadruplex structures in a 44-nucleotide long sequence found near the promoter region of the SMARCA4 gene was reported. The central 25 nucleotides were able to fold into an antiparallel G-quadruplex structure, the stability of which was pH-dependent. In the present work, the effect of the presence of lateral nucleotides and the complementary cytosine-rich strand on the stability of this G-quadruplex has been characterized. Moreover, the role of the model ligand TMPyP4 has been studied. Spectroscopic and separation techniques, as well as multivariate data analysis methods, have been used with these purposes. The results have shown that stability of the G-quadruplex as a function of pH or temperature is greatly reduced in the presence of the lateral nucleotides. The influence of the complementary strand does not prevent the formation of the G-quadruplex. Moreover, attempts to modulate the equilibria by an external ligand led us to determine the influence of the TMPyP4 porphyrin on these complex equilibria. This study could eventually help to understand the regulation of SMARCA4 expression
The Global Deterioration Scale for Down Syndrome Population (GDS-DS): A Rating Scale to Assess the Progression of Alzheimer’s Disease
Global deterioration scale; Down syndrome; Alzheimer’s diseaseEscala de deteriorament global; Síndrome de Down; Malaltia d'AlzheimerEscala de deterioro global; Síndrome de Down; Enfermedad de AlzheimerThe aim of this study is to adapt and validate the global deterioration scale (GDS) for the systematic tracking of Alzheimer’s disease (AD) progression in a population with Down syndrome (DS). A retrospective dual-center cohort study was conducted with 83 participants with DS (46.65 ± 5.08 years) who formed the primary diagnosis (PD) group: cognitive stability (n = 48), mild cognitive impairment (n = 24), and Alzheimer’s disease (n = 11). The proposed scale for adults with DS (GDS-DS) comprises six stages, from cognitive and/or behavioral stability to advanced AD. Two neuropsychologists placed the participants of the PD group in each stage of the GDS-DS according to cognitive, behavioral and daily living skills data. Inter-rater reliability in staging with the GDS-DS was excellent (ICC = 0.86; CI: 0.80–0.93), and the agreement with the diagnosis categories of the PD group ranged from substantial to excellent with κ values of 0.82 (95% CI: 0.73–0.92) and 0.85 (95% CI: 0.72, 0.99). Performance with regard to the CAMCOG-DS total score and orientation subtest of the Barcelona test for intellectual disability showed a slight progressive decline across all the GDS-DS stages. The GDS-DS scale is a sensitive tool for staging the progression of AD in the DS population, with special relevance in daily clinical practice.This research was funded by the Spanish Government, grant number PI12/02019, PSI-2014-53524-P.

Communicating communitarian approach
In times of crisis it is good and necessary reflecting on some basic elements of our profession and to take this opportunity to relate the different actors who are constructing our daily discipline. On the one hand, the academic side, this includes professors who are responsible for teaching and research, and students, who are the future of the profession. On the other hand, the professional world comprising the heads of government and social institutions that provides social services and social welfare, and the professionals who carry out their functions. From the relationship between this set of stakeholders arise difficulties and possibilities. It is essential that the Social Work make a set of approaches that turn their threats into opportunities and strengthen our contribution to society.</p
Near-field chipless-RFID system with high data capacity for security and authentication applications
A high data capacity chipless radio frequency identification (chipless-RFID) system, useful for security and authentication applications, is presented in this paper. Reading is based on the near-field coupling between the tag, a chain of identical split-ring resonators (SRRs) printed on a (typically flexible) dielectric substrate (e.g., liquid crystal polymer, plastic, and paper), and the reader. Encoding is achieved by the presence or absence of SRRs at predefined (equidistant) positions in the chain, and tag identification (ID) is based on sequential bit reading. Namely, the tag must be longitudinally displaced, at short distance, over the reader, a microstrip line loaded with an SRR and fed by a harmonic signal. By this means, the harmonic signal is amplitude modulated, and the (ID) code is contained in the envelope function, which can be obtained by means of an envelope detector. With this system, tag reading requires proximity with the reader, but this is not an issue in many applications within the domain of security and authentication (e.g., secure paper for corporate documents and certificates). Several circularly shaped 40-bit encoders (implemented in a commercial microwave substrate), and the corresponding reader, are designed and fabricated as proof-of-concept demonstrators. Strategies for programming the tags and a first proof-of-concept chipless-RFID tag fabricated on plastic substrate through inkjet printing are included in this paper
