As a continuation of previous research on the naturalization of non-native vascular plants in the Iberian Peninsula new chorological data are presented for 16 xenophytes recorded between 2010 and 2014, mostly in the provinces of Huelva and Barcelona (Spain) and in the Algarve and Estremadura (Portugal). For each taxon details about distribution, habitats occupied, previous records, degree of naturalization, etc. are provided. Lachenalia bulbifera and Cyperus albostriatus are probably reported for the first time in the wild in Europe, as are Gamochaeta filaginea, and Dysphania anthelmintica and Oenothera lindheimeri for Portugal and Spain respectively. Cosmos bipinnatus is cited as a novelty for the Algarve (Portugal). Newly reported or confirmed for the province of Huelva are: Amaranthus hypochondriacus, Epilobium brachycarpum, Nephrolepis cordifolia, Ficus microcarpa, Tamarix parviflora and Tamarix ramosissima, while Atriplex semibaccata, Chloris truncata, and Elymus elongatus subsp. ponticus are new for Barcelona. Finally, Passiflora caerulea is a novelty for both Barcelona and Huelva provinces.

Studies on the flora and fauna of the Canary Islands show that this Archipelago is one of the planet’s diversity hot spots. However, an analysis of the differences in the phytogeographic characteristics of each of the islands that make up this Archipelago is lacking. This article focuses on the phytogeographic characterization of the island of Gran Canaria. This island exhibits geological and climatic characteristics resulting in a rich vascular flora, including endemic species and genera that are significantly different from the other islands of the Archipelago. These differences are verified through statistical analysis of the existing similarity between the floras of the members of the Canary Islands. This study also analyses the subdivision of Gran Canaria Island, indicating that there are three well-differentiated areas on the island itself. Finally, this study argues that these areas, themselves, should be considered biogeographic sectors.

We present descriptions of a new order (Ranunculo cortusifolii-Geranietalia reuteri and of a new alliance (Stachyo lusitanicae-Cheirolophion sempervirentis) for the herbaceous fringe communities of Macaronesia and of the southwestern Iberian Peninsula, respectively. A new alliance, the Polygalo mediterraneae-Bromion erecti (mesophilous post-cultural grasslands), was introduced for the Peninsular Italy. We further validate and typify the Armerietalia rumelicae (perennial grasslands supported by nutrient-poor on siliceous bedrocks at altitudes characterized by the submediterranean climate of central-southern Balkan Peninsula), the Securigero-Dasypyrion villosae (lawn and fallow-land tall-grass annual vegetation of Italy), and the Cirsio vallis-demoni-Nardion (acidophilous grasslands on siliceous substrates of the Southern Italy). Nomenclatural issues (validity, legitimacy, synonymy, formal corrections) have been discussed and clarified for the following names: Brachypodio-Brometalia, Bromo pannonici-Festucion csikhegyensis, Corynephoro-Plantaginion radicatae, Heleochloion, Hieracio-Plantaginion radicatae, Nardetea strictae, Nardetalia strictae, Nardo-Callunetea, Nardo-Galion saxatilis, Oligo-Bromion, Paspalo-Heleochloetalia, Plantagini-Corynephorion and Scorzoneret alia villosae.

Biomechanical problems in children, is an important subject currently, existing controversy in different areas, for example, the majority of children have a flattened footprint, or the hypermobility joint is linked to a musculoskeletal pain. The objective of the study was to determine what kind of footprint is most frequent in school-age children (8-10 years) in the area of Plasencia. This was taken as a sign 50 children, of whom 28 were males and 22 females. All the subjects in the study underwent an assessment of footprint planted in static as well as an exploration of different parameters through inspection in a standing position (formula digital, rearfoot). The results show that excavated footprint is present in a 72% cases of the population, 16% was belonging to an excavated footprint in which we find a higher percentage of weight related.For the digital formula we find that the most common is the Egyptian foot by 40% of the cases and that the prevalence in the rearfoot, is a normal hindfoot. In relation with the hypermobility joint, we check that it is more common in girls and that none of them presents an association to musculoskeletal pain. As a future line we could establish a more comprehensive study with new techniques and valuingchild’s statics and dynamics, to have a more accurate study of the different variables in the sample population studied.

The work analyse from a journalistic point of view the history radio divulgation of health during the Second Republic and the start of the Franco era. For it, printed sources of the health broadcast conferences have been analysed. The most frequently used radio genre was a combination of informative monologue and monologue opinion. Questions relating to maternal-juvenile health were the most disseminated. In general, the radio language employed responded to the needs for clarity, as well as adapting the message to the target audience. With Francoism, the political slogans were incorporated and the gender discussions were given more importance.

this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.

Se propone un planteamiento teórico/conceptual para determinar si las relaciones interorganizativas e interpersonales de la netchain de las cooperativas agroalimentarias evolucionan hacia una learning netchain. Las propuestas del trabajo muestran que el mayor grado de asociacionismo y la mayor cooperación/colaboración vertical a lo largo de la cadena están positivamente relacionados con la posición horizontal de la empresa focal más cercana del consumidor final. Esto requiere una planificación y una resolución de problemas de manera conjunta, lo que está positivamente relacionado con el mayor flujo y diversidad de la información/conocimiento obtenido y diseminado a lo largo de la netchain. Al mismo tiempo se necesita desarrollar un contexto social en el que fluya la información/conocimiento y las nuevas ideas de manera informal y esto se logra con redes personales y, principalmente, profesionales y con redes internas y, principalmente, externas. Todo esto permitirá una mayor satisfacción de los socios de la cooperativa agroalimentaria y de sus distribuidores y una mayor intensidad en I+D, convirtiéndose la netchain de la cooperativa agroalimentaria, así, en una learning netchain.

Since remote times, certain sectors of society have been exposed to inequality and vulnerability, where adequate intervention processes have become conspicuous because of their absence. Nowadays, current societies have the responsibility of contributing, based on their experience and knowledge, with more efficient policies and programs that improve the life quality of the most disadvantaged. It is here where art and its different tools play a very important role, not only on a physical level, but also as an education tool that allows the development of emotional, mental and communicative skills. The aim of this paper is to make clear the potential of art as an instrument of social and educational intervention. It starts by showing worldwide-collected experience related to education and arts, and then, it acquaints the reader with two parallel intervention projects that worked with youths under social vulnerability conditions. These interventions were developed based on a qualitative research (Grounded theory), using as methodology “The Artistic Mediation” with emphasis on body language. This methodology helped researchers to get close to the participants and to know their experiences and emotions. At the same time, it was possible to evidence the positive effects of educative interventions through art. These workshops were based on an artistic methodology especially focused on body language. Data in this work is qualitative, and as such, it permits a special approach to the personal and emotional experiences of the participants; clearly showing the positive effects of the referenced practice on them.

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.

La Anunciación del Monasterio de Santo Domingo de Caleruega, fundado por Alfonso X el Sabio, ha permanecido prácticamente olvidada por la historiografía nacional. Aislado tras los muros de la clausura, el grupo escultórico presenta una particularidad que, durante mucho tiempo, no fue analizada convenientemente: la Virgen está embarazada. La cantidad de ejemplos contabilizados de la misma naturaleza demuestra que esta clase de representaciones fue habitual, durante la Baja Edad Media, en algunos reinos de la península ibérica. Con un enfoque fundamentalmente iconográfico pero sin renunciar a otra clase de aproximaciones, el presente artículo pretende estudiar en profundidad la singularidad de la Anunciación calerogana que, al mismo tiempo, se convierte en el punto de partida para un análisis global de esta variante de la Salutación Angélica.

En estas páginas se pretende proponer un modo de entender lo visto siempre como adaptación inmanente, deseo y simbolización, esto es, entenderlo como imagen. Se hará conforme a un concepto de ‘superficie’ que prolonga la lectura que hiciera Didi-Huberman del concepto de imagen-síntoma de Aby Warburg, y se apoya en textos de teoría psicoanalítica de la mano de Jacques Lacan, en un intento no de arruinar la capacidad de hermenéutica del observador, sino de entender la búsqueda del sentido y de la esencia –del arte por ejemplo– como la investigación sobre un conflicto histórico de pérdidas, crisis y memoria. ‘Superficie’ en tanto que masa átona y sin sentido donde el ojo siempre visiona formas: ver superficie es que el ojo siempre adapte lo visto, deseando abrirlo visionariamente en su significado para recabar su verdad oculta, pero paradójicamente cerrándolo. Porque mirar imágenes supone siempre perder visión respecto de una supuesta totalidad en la que se darían todos los significados en todas sus ambigüedades y en todas sus posibilidades históricas, pérdida sólo decible en su retorno en tanto que resignificación traumática. Aquí postulamos que la ilusión será creer no que las apariencias son ilusorias, sino que más allá de ellas hay “más realidad”. Este planteamiento no sólo ratifica la posición del sujeto, inserto en una superficie/cuadro dada-a-ver, sino que descubre la brecha constitutiva que le rige y que es un “más en él” que él mismo.

In this paper we present the first data from the research conducted to determine the relationship between traditional visual arts and other forms of visual culture closer to the experiences of high school youth. The hypothesis of this research is that while students are nurtured and live primarily with the images provided by the media culture, their textbooks basically refer to the more traditional art images. The research has been limited to a review and analysis of the most common educational materials for teaching visual arts in high school. After the systematization and analysis of the images appeared in textbooks, we have detected three major types: the artistics, those who belong to media culture and others. The most relevant conclusions indicate that: there are hardly any connections between different types of images, they offer a very traditional view of art and they are far removed from the experiences of young book users.
