El objetivo de esta comunicación es dar a conocer el proyecto ERASMUS+ Inside out- Outside In- Building bridges in teacher education through encounters with diversity en el que participan ocho instituciones europeas de formación de profesores de Alemania, Austria, España, Estonia, Finlandia, Hungría, Reino Unido y Suecia, que es la coordinadora. Uno de los retos que deben afrontar los sistemas educativos en el futuro inmediato es sin duda la diversidad cultural del alumnado, en sentido amplio, ya que consideramos que esa diversidad no viene dada sólo por la lengua, procedencia, religión o etnia del alumnado, sino también por las expectativas y valores con que se enfrentan a la educación. Esos diferentes valores están en la base de gran parte del abandono escolar temprano, cuya reducción es uno de los objetivos que se ha marcado la Unión Europea. Esa tasa es en España la más alta de Europa, aunque con enormes diferencias de unas Comunidades Autónomas a otras. Los movimientos migratorios de población de dentro y fuera de la Unión Europea, unidos a la llegada de refugiados, están cambiando la fisonomía de nuestras aulas y exigen de todos los que nos dedicamos a la docencia en todos los niveles cambios para responder a las nuevas demandas. Los conceptos de arraigo y desarraigo (insideness and outsideness) son básicos por sus implicaciones en la creación de espacios de aprendizaje que se reconozcan como tales y que puedan serlo realmente; además, implican romper las fronteras entre educación formal y no formal de forma que cualquier momento y cualquier espacio puedan convertirse en espacios y tiempos educativos.

Along this work we wish to highlight the main influence of Procedural Law in some as-pects in our Maritime Law. Our point of view has been supported by new Maritime Naviga-tion Act of 2014, when including the Title X ruling "Procedures Specialities in Maritime Navigation". We are focusing on the Bill of Lading as an essential document in maritime shipping from a procedural point of view. It is particulary relevant the express recognition of its enforce-able nature through the Spanish Maritime Navigation Act, giving to the bill of lading the consideration as an true extrajudicial enforceable title. We will point out the main error of the spanish regulator in the new Maritime Navigation Act, when repeating the provided posibility in the Spanish Civil Procedure Act, of a direct procedure of execution grounded on a extrajuditial enforcement such as the bill of lading. Finally, we would like to conclude the work studying the possible uses of Small Claim Procedure of the 812 article and followings of Spanish Civil Procedure Law, for the pur-pose of safeguarding credit, so as a short mention to other procedural figures expressly in-cluded in the Title IX of Maritime Navigation Law.

La presente ponencia se centra en identificar y analizar las prácticas transformadoras del Trabajo Social actual ante los escenarios de complejidad en los que se desarrolla su actuación profesional. El actual contexto social de adversidad ha acentuado la concepción transformadora que acompaña al Trabajo Social desde sus inicios, dando lugar a múltiples contribuciones desde la práctica orientadas al cambio. Situarse desde ellas, para reenfocar y reflexionar sobre la intervención social que requiere el momento actual, es el objetivo principal de este trabajo. Partiendo de una revisión teórica que sitúe los antecedentes y evidencias empíricas relacionadas, se analizan las buenas prácticas profesionales allí donde el Trabajo Social está presente, como los sistemas públicos de servicios sociales y otras realidades asociadas a la iniciativa social. Se concluye sobre la utilidad y fortalecimiento de estrategias alternativas, creadoras de nuevos recursos, de recuperación de lo comunitario y enfocadas desde la perspectiva de la resiliencia.

Los dialectos son parte de la herencia cultural de un pueblo. Se trata de una herencia intangible, pero fundamental. En nuestro proyecto, los dialectos y sus correspondientes variedades estándar serán consideradas no solo como herencia estática documentada, sino también como herencia viva y en continuo cambio, afectada por dinámicas sociales, esquemas culturales y constructos cambiantes de identidad propios de sociedades globalizadas. El objetivo general del proyecto es describir y explicar —para entender— el estatus actual de la variedad lingüística del español en Málag

Mercury is not an essential element for plant or animal life and it is a potential environmental toxic because of its tendency to form covalent bonds with organic molecules and the high stability of the Hg-C bond. Reports estimate a total mercury concentration in natural waters ranging from 0.2 to 100 ng L-1. Due to this fact, highly sensitive methods are required for direct determination of such extremely low levels. In this work, a rapid and simple method was developed for separation and preconcentration of mercury by flow injection solid phase extraction coupled with on-line chemical vapour generation electrothermal atomic absorption spectrometry. The system is based on chelating retention of the analyte onto the mini column filled with a mesoporous silica functionalized with 1,5 bis (di-2-pyridyl) methylene thiocarbohydrazide. The main aim of this work was to develop a precise and accurate method for the determination of the Hg. Under the optima conditions and 120 s preconcentration time, the detection limit obtained was 0.009 μg L-1, with RSDs 3.7 % for 0.2 μg L-1, 4.8 % for 1 μg L-1 and enrichment factor 4, Furthermore, the method proposed has permitted the determination of Hg with a reduction in the analysis time, the sample throughput was about 18 h-1, low consumption of reagents and sample volume. The method was applied to the determination of Hg in sea water and river water. For the quality control of the analytical performance and the validation of the newly developed method, the analysis of two certified samples, TMDA 54.4 Fortified Lake, and LGC6187 River sediment was addressed. The results showed good agreement with the certified values.

Esta comunicación muestra el estado de desconsideración actual de la educación artística que, como docentes del Área de Didáctica de la Expresión Plástica de la Universidad de Málaga, detectamos en el alumnado que accede, año tras año, al Grado Grado de Maestro/a en Educación Primaria. La adquisición de consciencia a la que el trabajo con este alumnado nos ha llevado, así como el autocuestionamiento continuo de nuestra actuación en el aula, ha generado una estructura para el análisis que nos permite minimizar este estado de deslegitimación de la educación artística fruto de un aprendizaje basado en un paradigma reproductivo, así como generar estrategias que, sometidas a una actualización constante, propician un aprendizaje consciente que, en ocasiones, se torna revelador.

The pan-Myosin Heavy Chain (pan-MyHC) marker MF20 have been reported to show similar, homogeneous signal in the myocardial segments of the heart of teleosts and tetrapods. However, in an ongoing study of the myocardial structure of the dogfish (Scyliorhinus canicula; Chondrichthyes), we observed differential immunostaining of the cardiac segments using another pan-MyHC, the A4.1025 antibody. In order to investigate the relevance of this finding for better understanding of the morphology and evolution of the vertebrate heart, we performed immunohistochemistry, slot blot and western blot in several species of chondrichthyans, actinopterygians and mammals using the above mentioned antibodies. In the dogfish heart, A4.1025 and MF20 specifically recognized MyHC isoforms, although with different degree of affinity. MF20 reactivity was homogeneous and high in all the myocardial segments. However, A4.1025 reactivity was heterogeneous. It was high in the sinus venosus (external layer), atrium and atrioventricular region, low in the ventricle and conus arteriosus, and null in the internal layer of the sinus venosus. A heterogeneous pattern of A4.1025 immunoreactivity was also detected in two other elasmobranchs, a holocephalan, a polypteryform and an acipenseriform. In all of these species, MF20 immunoreactivity was homogeneous. In addition, both markers showed a homogeneous immunoreactivity pattern in teleosts and mammals. Our results indicate that in the hearts of ancient gnathostomes, in all of which a conspicuous conus arteriosus exists, one or more MyHC isoforms with low affinity for A4.1025 show segment-specific distributions. Thus, A4.1025 appears to be an appropriated marker to identify the cardiac segments and their boundaries. We propose that the segmentspecific distribution of MyHC isoforms may generate a particular type of myocardial contractility associated with the presence of a conus arteriosus.

Recent work has shown that the cardiac outflow tract of sharks and chimaeras does not consist of a single myocardial component, the conus arteriosus, as classically accepted, but two, namely, the myocardial conus arteriosus and the non-myocardial bulbus arteriosus. However, the anatomical composition of the outflow tract of the batoid hearts remains unknown. The present study was designed to fill this gap. The material examined consisted of hearts of two species of rays, namely, the Mediterranean starry ray (Raja asterias) and sandy ray (Leucoraja circularis). They were studied using scanning electron microscopy, and histochemical and inmunohistochemical techniques. In both species, the outflow tract consists of two components, proximal and distal with regard to the ventricle. The proximal component is the conus arteriosus; it is characterized by the presence of compact myocardium in its wall and several transverse rows of pocket-shaped valves at its luminal side. Each valve consists of a leaflet and its supporting sinus. Histologically, the leaflet has two fibrosas, inner and outer, and a middle coat, the spongiosa. The distal component lacks myocardium. Its wall consists of smooth muscle cells, elastic fibers and collagen. Thus, it shows an arterial-like structure. However, it differs from the aorta because it is covered by the epicardium and crossed by coronary arteries. These findings indicate that the distal component is morphologically equivalent to the bulbus arteriosus of sharks and chimaeras. In contrast to foregoing descriptions, the valves of the first transverse row are distally anchored to the bulbus arteriosus and not to the ventral aorta. Our findings give added support to the notion that presence of a bulbus arteriosus at the arterial pole of the heart is common to all chondrichtyans, and not an apomorphy of actinopterygians as classically thought.

La montaña media mediterránea ha sido históricamente un espacio muy transformado por la acción humana, lo cual se constata en la actualidad con la presencia de un mosaico de diferentes tipos de usos del suelo, haciendo que ésta presente una dinámica medio ambiental y socioeconómica muy compleja. El siguiente trabajo tiene como objetivo analizar las principales transformaciones en los aprovechamientos y en la cubierta vegetal de los últimos sesenta años en el municipio de Faraján (Málaga). Para ello, se lleva a cabo la fotointerpretación de ortoimágenes e imágenes aéreas en combinación con fuentes bibliográficas. Como resultados preliminares se pueden indicar, por un lado, el incremento de la superficie cultivada de castañar, y por otro, el aumento de la cubierta vegetal natural en detrimento de otros usos. Dichos cambios conllevan una serie de consecuencias en aspectos tan importantes como la erosión y la disponibilidad de recursos hídricos, tan necesarios de tener en cuenta a la hora de implementar una gestión territorial más acorde con la evaluación histórica de los usos del suelo y el marco actual de cambio climático.

Resumen: Los avances en la industria del acero y la aparición de nuevos materiales con mejores propiedades físico-químicas y mejor comportamiento frente a fenómenos de corrosión, está promoviendo tanto el desarrollo de las técnicas analíticas ya existentes (convencionales) como la búsqueda de tecnologías alternativas que permitan la caracterización y análisis on-line del acero durante el proceso de producción del mismo, abarcando desde las materias primas hasta los productos finales, incluyendo aceros con distintos tipos de recubrimiento metálico (aceros galvanizados). En la actualidad la tecnología láser, junto con avanzadas herramientas quimiométricas, es una poderosa técnica para la caracterización, monitorización y la determinación de la composición química de este tipo de materiales. En este trabajo se presentarán algunas de las aplicaciones más significativas (en diferentes factorías como TKS en Alemania o Gerdau y Acerinox en España) de la espectrometría de emisión atómica de plasmas inducidos por láser (LIBS) para la determinación de la composición elemental de aceros inoxidables tanto a temperatura ambiente como hasta 900 ºC, haciendo hincapié en la versatilidad y flexibilidad de la técnica para el análisis on-line e in situ de muestras de acería y productos acabados.

Background Cerebrospinal fluid accumulation in hydrocephalus produces an elevation of intraventricular pressure with pathological consequences on the periventricular brain parenchyma including ischemia, oedema, oxidative stress, and accumulation of metabolic waste products. Here we studied in the hyh mouse, an animal model of congenital hydrocephalus, the role of reactive astrocytes in this clinical degenerative condition. Materials and Methods Wild type and hydrocephalic hyh mice at 30 days of postnatal age were used. Three metabolites related to the oxidative and neurotoxic conditions were analysed in ex vivo samples (glutathione, glutamine and taurine) using High Resolution Magic Angle Spinning (HR-MAS). Glutathione synthetase and peroxidase, glutamine synthetase, kidney-type glutaminase (KGA), and taurine/taurine transporter were immunolocated in brain sections. Results Levels of the metabolites were remarkably higher in hydrocephalic conditions. Glutathione peroxidase and synthetase were both detected in the periventricular reactive astrocytes and neurons. Taurine was mostly found free in the periventricular parenchyma and in the reactive astrocytes, and the taurine transporter was mainly present in the neurons located in such regions. Glutamine synthetase was found in reactive astrocytes. Glutaminase was also detected in the reactive astrocytes and in periventricular neurons. These results suggest a possible protective response of reactive astrocytes against oxidative stress and neurotoxic conditions. Conclusions Astrocyte reaction seems to trigger an anti-oxidative and anti-neurotoxic response in order to ameliorate pathological damage in periventricular areas of the hydrocephalic mice.

Child sexual abuse (CSA) disclosure is critical for survivor´s psychosocial adjustment later in life. The aim of the present study was to analyze the relationship between attributions of blame for child sexual abuse by the victim and the disclosure of the abuse to parents or caregivers while controlling for characteristics of the abuse. Female college students between 17 and 24 years of age (M = 19.44, SD = 1.64) from a southern Spanish University were surveyed. Of 1547 respondents, 153 (9.90%) reported having suffered some form of CSA before the age of 15. Information about the characteristics of abuse (age of onset, type of abuse suffered, continuity of abuse, and relationship with and age of the perpetrator) and the existence of abuse disclosure by the survivor was obtained from a self-reported questionnaire developed for the present study. The Attributions of Responsibility and Blame Scale (McMillen & Zuravin, 1997) was used to assess attributions made about CSA (self-blame, perpetrator blame and family blame). The results of a logistic regression model was statistically significant, χ² (9) = 43.856, p < .001. The model explained 41% (Nagelkerke R²) of the variance of abuse disclosure and correctly classified 85.6% of cases. Survivor disclosure was 5.50 times more likely to occur when the perpetrator was not a family member (Wald = 8.14, p < .01) and 3.95 times more likely to occur when there was not physical contact with the perpetrator (Wald = 4.30, p < .05). The occurrence of disclosure was also related to increased perpetrator age (Wald = 4.83, p < .05). With regard to the attributions of blame, the occurrence of disclosure was related to lower scores on self-blame (Wald = 6.78, p < .01) and higher scores on family blame (Wald = 9.67, p < .001). However, no relationship was found between perpetrator blame and disclosure of abuse. The results confirm the idea that not only self-blame attributions, but also family blame attributions are critical to the decision of a CSA victim to disclose abuse. The possibility that children who do not disclose abuse have a greater need to deny the occurrence of abuse, or have more confusion about being abused is discussed. Attributions of blame should be taken into serious consideration when evaluating children for possible sexual abuse.

We have shown Galanin(GAL) and Neuropeptide Y Y1(NPYY1) interactions at behavioural, cellular and receptor levels through GALR2/NPYY1R heterodimers in the amygdala. The aim of this work was to analyze GAL/NPYY1R interactions in the Dentate Gyrus(DG) of the Hippocampus, using autoradiographic, in situ hybridization and in situ proximity ligation assay(PLA). Rats(n=6) were sacrificed 15 minutes or 5 hours after icv injections of GAL(3nmol) and DG sections were incubated with NPYY1R agonist [I125]-[Leu31,Pro34]PYY(25 pM) or NPYY1R-33PdATP specific probe, for autoradiography and in situ hybridization respectively. Autoradiograms were analyzed using NIH image analysis system and Student’s unpaired t-test was used. For PLA, DG sections were incubated with anti-GALR2 Rabbit(1:100) and anti-NPYY1R Goat(1:200). PLA signals were detected with PLA PLUS or MINUS probes for rabbit or goat/mouse antibodies. PLA signals were visualized by using a confocal microscope Leica TCS-SL confocal microscope(Leica). We observed that GAL significant increased the NPYY1R agonist [I125]-[Leu31,Pro34]PYY binding in the DG by 20% (p<0,05) and the NPYY1R mRNA expression in the granular layer of DG by 31% (p<0,001). Moreover, PLA-positive red clusters were found specifically in the polymorphic layer and subgranular zone of the DG. No PLA clusters were observed neither in the molecular layer of the DG nor in the corpus callosum, an area that seems to lack of GALR2 receptor. These results demonstrate a novel mechanism of interaction between GAL and NPY1R in the DG at receptor level, probably involving the formation of GALR2/NPYY1R heteroreceptor complexes.
