New records of vascular plants from Sierra del Rincón Biosphere Reserve and surroundings (Spain, Madrid province) are provided. It is noteworthy the presence of atlantic flora in this continental area and the different shrubby communities in different sectors with different litology: in areas with gneiss they are dominated by leguminous genisteae; where it is schistous, shale or quartzite they are heathlands.

Sandy shores are known to be extreme ecosystems where the vegetation has evolved many morphological and physiological adaptations for its survival. With the aim of identify possible relationships between the vegetation´s functional diversity with abiotic factors and its corresponding quantification, we collected data on the abundance and richness of the sandy coast vegetation complex in Grande, Anclitas and Caguamas keys. Its flora is largely characterized by the dominance of hemicryptophytes and chamaephytes plants with nanophyllous leaves and displaying dispersal syndromes such as zoochory and anemochory. However, the functional groups´ richness, in the present study, varies from one key to another. Functional diversity is similar between the wet and dry seasons, and its spatial variation is influenced by the interplay of the set of abiotic factors herein studied.

Xanthoria parietina, common foliose lichen, growing in its natural habitat, was analysed for the concentration of five heavy metals (Fe, Cr, Zn, Pb and Cu) from different forest sites of North East of Morocco (Kenitra, Sidi Boughaba, Mkhinza, Ceinture Verte near Temara city, Skhirate, Bouznika and Mohammedia). The quantification was carried out by inductively coupled plasma - atomic emission spectrometry (ICP-AES). Results were highly significant p<0,001. The concentration of metals is correlated with the vehicular activity and urbanization. The total metal concentration is highest at the Kenitra area, followed by Ceinture Verte site near Temara city, which experience heavy traffic throughout the year. Scanning electron microscopy (SEM) of particulate matter on lichen of Xanthoria parietina was assessed as a complementary technique to wet chemical analysis for source apportionment of airborne contaminant. Analysis revealed high level of Cu, Cr, Zn and Pb in samples near roads.

Food is one of the main exogenous sources of genotoxic compounds. In heated food products, polycyclic aromatic hydrocarbons (PAHs) represent a priority group of genotoxic, mutagenic and/or carcinogenic chemical pollutants with adverse long-term health effects. People can be exposed to these compounds through different environments and via various routes: inhalation, ingestion of foods and water and even percutaneously. The presence of these compounds in food may be due to environmental contamination, to industrial handling and processing of foods and to oil processing and refining. The highest levels of these compounds are found in smoked foods, in seafood which is found in polluted waters, in grilled meats and, to a lesser extent, in vegetable fats and oils. Lower levels of PAHs are found in vegetables and in cereals and its products.

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.

Este trabajo tiene como propósito esencial, realizar un acercamiento para detectar e identificar las necesidades de información y el comportamiento informativo de entrenadores en deportes de combate. Para ello se aplicó un cuestionario a instructores de aikido, boxeo, esgrima, judo, karate, kendo, lima lama, lucha y taekwondo seleccionados mediante un muestreo no probabilístico por causalidad. En general encontramos que los principales temas de interés entre los instructores son: los programas de entrenamiento, nutrición y dietas de entrenamiento. Por otra parte, los entrenadores son más propensos a utilizar su experiencia, internet y cursos para obtener información. En contraste se nota que la biblioteca y los libros son poco usados.

Reality shows are TV programs which represent a format used in television nowadays; however, the observation practices of individual and/or group intimacy dates from thousands years ago. Sometimes this was driven by voyeurism or morbid fascination, some others, by the purpose of guarding, supervising and maintaining status quo. This work offers an alternative answer to the explanation of this type of TV program emergence and relates this appearance to a government procedure bound up with modern State terrorism which began at the end of the eighteenth century and has been recalled by different regimes until present days.

There is abundant empirical evidence on the negative relationship between welfare effort and poverty. However, poverty indicators traditionally used have been representative of the monetary approach, excluding its multidimensional reality from the analysis. Using three regression techniques for the period 1990-2010 and controlling for demographic and cyclical factors, this paper examines the relationship between social spending per capita —as the indicator of welfare effort— and poverty in up to 21 countries of the region. The proportion of the population with an income below its national basic basket of goods and services (PM1) and the proportion of population with an income below 50% of the median income per capita (PM2) were the two poverty indicators considered from the monetarist approach to measure poverty. From the capability approach the proportion of the population with food inadequacy (PC1) and the proportion of the population without access to improved water sources or sanitation facilities (PC2) were used. The fi ndings confi rm that social spending is actually useful to explain changes in poverty (PM1, PC1 and PC2), as there is a high negative and signifi cant correlation between the variables before and after controlling for demographic and cyclical factors. In two regression techniques, social spending per capita did not show a negative relationship with the PM2. Countries with greater welfare effort for the period 1990-2010 were not necessarily those with the lowest level of poverty. Ultimately social spending per capita was more useful to explain changes in poverty from the capability approach.

Taking into account the huge repercussion and influence that J.J. Rousseau has had on modern pedagogy, the recent tercentenary of his birth is a good opportunity to think about his outstanding relevance nowadays. This paper is a theoretical and educative research developed with an analytic and comparative hermeneutical method. The main objective is to show how some concepts of his philosophy of education have a great similarity with certain changes that the present competency based teaching is demanding, so it could be considered its methodological background. In order to achieve this objective this exposure has been divided in three parts. The first part is an analysis of Rousseau's educational theory as developed in the first three books of the Emilio, in which one of the main themes is self experience-based learning, fostering self-sufficiency, curiosity and the motivation for learning. Rousseau proposed as a method the negative education, which requires, among other conditions, a constant monitoring of the learner by the tutor. In the second part, a brief summary of the most relevant changes and characteristics of competency-based teaching is developed, as well as its purpose. The student’s participation and activity are highlighted within their own learning process through the carrying out of tasks. The new educational model involves a radical change in the curriculum, in which it is highlighted the transformation of the methodology used in the classroom as well as the role of the teacher. Finally, the aim of the third part is to offer a comparative synthesis of both proposals grouping the parallelisms found in 4 topics: origin of the two models, its aims, methodology, and change in the teaching roles.

To understand academic performance of students, the variable of conscientiousness from personality inventory Big Five, has been recognized as an important key. The aim of this paper is to analyze the relationship established between the personality factor conscientiousness itself and two of its facets, laboriousness and planning, with academic performance, and observe if there are genre differences in consciousness personality factor. A total of 456 Spanish students of high school and college participated in the study. They were requested to answer a personality report and a self inform questionnaire. The results show that both conscientiousness as a personality dimension and the consideration of laboriousness facet are able to predict academic performance, especially with regard to student’s exam marks, classroom attendance and dedication to study. The genre variable pointed out that feminine genre is more conscious than male in that personality factor. From a practical perspective, these results indicate that the establishment of a routine of continuous work is suitable for improving student grades and their adaptation to the educational environment.

A pesar de la progresiva introducción de nuevos recursos en las aulas fruto del desarrollo de las TICs, el libro de texto sigue siendo uno de los materiales más utilizado y cuyo protagonismo en la configuración de la práctica escolar ha sido decisivo, por lo que debe ocupar nuestra atención en la formación inicial de los profesionales de la educación. Durante los cursos académicos 2012-13 y 13-14, hemos realizado en el marco de la asignatura de Análisis y diseño de materiales para la educación y la formación del tercer curso del grado de Pedagogía de la Universidad de Oviedo una práctica formativa de análisis de libros de texto escolares que nos ha permitido analizar contextualizadamente y desde una perspectiva teórico-práctica, cuestiones tales como: papel del profesorado en el desarrollo e innovación del currículum, papel de las editoriales en la interpretación del currículum oficial, análisis de tareas y mensajes en los manuales escolares, criterios para juzgar la calidad didáctica de los materiales, etc. El análisis cualitativo de treinta informes desarrollados por 120 estudiantes sobre diferentes libros de texto nos ha permitido identificar sus principales fortalezas y debilidades en varias dimensiones (aspectos formales, metodología, mensajes, implicaciones para la profesionalidad docente) y nos permite concluir que se trata de una experiencia formativa relevante en la formación inicial de cualquier profesional de la educación.

La necesidad de contar con un mapa de base científica que cubriera todo el territorio español llevó al Estado a crear en paralelo varias Comisiones con cometidos geodésicos, topográficos y cartográficos durante la década de 1850. La labor simultánea de estas Comisiones se prolongó hasta 1859, cuando se aprobó la Ley de Medición del Territorio, que las fusionó en un único organismo. Este artículo analiza aspectos técnicos de los trabajos que realizaron estas Comisiones a partir de la información contenida en algunos documentos que custodia el Archivo Topográfico del IGN. Las conclusiones que se extraen son que estas Comisiones acometieron operaciones geodésicas que resultaron cruciales en el establecimiento ulterior de la red de triangulación peninsular, realizaron mediciones topográficas que fueron reutilizadas veinte años después en el levantamiento del Mapa Topográfico Nacional, e idearon las características catastrales que fueron adoptadas durante todo el siglo posterior para el Catastro de España.

Este artículo resulta de investigaciones en torno al “enverdecimiento” de las ciudades y las oportunidades de la agricultura urbana para la alimentación de una población en constante aumento que no trabaja la tierra. También es fruto de actividades de mejora de ambientes urbanos realizadas con la Escuela de Ingenieros Agrónomos de la Universidad Politécnica de Madrid. A través de casos de agricultura urbana, entendiendo por ella el conjunto de prácticas para la producción de alimentos y plantas ornamentales dentro de las ciudades y en sus entornos, se analizan alternativas para la recuperación de espacios construidos e incremento de la calidad de vida de la población. Todo ello se traduce, además, en creación de riqueza y mejora del paisaje urbano, siempre desde criterios de sostenibilidad que favorecen el desarrollo local desde la Cumbre de la Tierra de Río de 1992 y la Conferencia sobre Desarrollo Sostenible Río+20 de 2013.

A medida que el concepto de "nación" se ha debilitado en estos últimos años, y de forma muy rápida, el límite convencional de la cultura se está desvaneciendo y el mundo se mueve hacia un orden cultural integrado, a través de intercambios constantes entre las culturas, a pesar de las barreras discriminatorias. La literatura, en este sentido, no es una excepción y es necesario discutir la relación entre la literatura coreana y la hispanoamericana desde la perspectiva de la literatura comparativa. El presente estudio ofrece una mirada más cercana al proceso y a los distintos aspectos del modo en que las obras de los escritores hispanoamericanos han sido aceptadas en Corea del Sur. La literatura hispanoamericana se ha introducido en Corea desde principios del siglo XX y se extendió rápidamente a partir de los ochenta, cuando la controversia literaria del posmodernismo se desató y las obras de Borges y García Márquez fueron presentadas a los lectores coreanos. Sería interesante examinar los aspectos sobre cómo los escritores hispanoamericanos como Neruda, Borges y García Márquez se han integrado en la literatura coreana. En esta etapa, sin embargo, es difícil determinar si su influencia es suficientemente permanente como para convertirse en un linaje, o simplemente se trata de un fenómeno temporal. No obstante, la literatura hispanoamericana seguirá expandiendo interrelaciones crecientes con la coreana más allá de las fronteras, ejerciendo una gran influencia entre sí.
