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.

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.

El objetivo principal de este trabajo es, a través de las noticias publicadas en diversos medios de comunicación de la Región de Extremadura sobre bibliotecas rurales a lo largo de los últimos años, comprobar el impacto y la visibilidad de las bibliotecas en los medios. Para ello, se recopilan un total de 1196 noticias que, tras ser analizadas detalladamente, se reducen a 300 sobre las que versan los resultados del estudio. Esta disminución de noticias finales demuestra que el titular o los primeros párrafos no expresan exactamente el contenido de la noticia siendo necesario un análisis cualitativo de su contenido. Se concluye que: las noticias sobre bibliotecas rurales han decrecido en el periodo analizado (2007, 2008, 2012, 2013), siendo 2007 el año de mayor auge, si bien se ha observado un repunte en 2013 con respecto a 2012; las noticias sobre bibliotecas rurales de ámbito provincial (Badajoz y Cáceres) obtienen mayor porcentaje que las regionales y nacionales (sin representación); y el diario HOY es, con diferencia, el medio que acumula el mayor porcentaje de noticias sobre bibliotecas rurales.

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.

Young people are less explored in museum audience research; this is a paradoxical situation when considering its strategic location in the cultural reproduction and if considering the high performing cultural consumption compared with other sectors. The phenomenon of museums consumption by young Chileans who are self recognized as public and non-public museums is explored from a qualitative approach. It was conducted with focus groups in the three largest cities in Chile (Santiago, Valparaíso and Concepción). They identify the museum as a cultural institution in full force. However, in questioning museums activity youth reveal the specificity of their cultural matrix. This is referred to a social temporality based on the fragment, the discourse of familiarity, proximity and instead of breaking and critical. They claim a museum aesthetic / historical experience based on pleasure and enjoyment. An overview is proposed to further clarify the youth cultural consumption to characterize more precisely the place of the museum in the set, to design more effective policies museums.

Between 1914 and 1923, and in general during the 1910s and 1920s, important changes occurred in the Asturian press that can be seen, for example, in the type of dailies which achieved certain readership levels. The form and number of pages evolved, images became more common, so-called citizen journalism was more freely practised, and there was a trend -when there was an opportunity- towards publishing articles which involved the author travelling to distant lands. Simultaneously, the consideration of sport as a show and the treatment given to other content both helped outline a new media scenario.

This article analyses the motivations for return migration among the Ecuadorians and Bolivians who, after living in Spain, returned to their countries of origin during the economic crisis that started in 2008. From the analysis of 22 interviews in-depth which took place in Ecuador and 38 in Bolivia to women, men and young people from migrant families, this decision-making process is shown to be embedded into a gendered dynamics of relationships. Particular detail is given to affective and economic elements that had an influence on the decision to return, as well as to the strategies deployed to project their readjustment back in origin. Males and females occupy differential positions within the family, work and social circle, their expectations being built in a gendered manner. Despite the fact migration has brought women greater economic power within the family group, their reintegration upon return redefines their role as main managers in the household and the dynamics that allow their social reproduction. Men, for their part, aspire to refresh their role as providers in spite of their frail labour position upon return. Social mobility for females is passed on through generations by a strong investment on education for their daughters and sons, while for males this mobility revolves around setting up family businesses and around their demonstrative abilities.

This paper presents the "state of the art" and some of the main issues discussed in relation to the topic of transnational migration and reproductive work in southern Europe. We start doing a genealogy of the complex theoretical development leading to the consolidation of the research program, linking consideration of gender with transnational migration and transformation of work and ways of survival, thus making the production aspects as reproductive, in a context of globalization. The analysis of the process of multiscale reconfiguration of social reproduction and care, with particular attention to its present global dimension is presented, pointing to the turning point of this line of research that would have taken place with the beginning of this century, with the rise notions such as "global care chains" (Hochschild, 2001), or "care drain" (Ehrenreich and Hochschild, 2013). Also, the role of this new agency, now composed in many cases women who migrate to other countries or continents, precisely to address these reproductive activities, is recognized. Finally, reference is made to some of the new conceptual and theoretical developments in this area.

En el presente trabajo se analiza la manera en la que el dramaturgo valenciano Andrés Rey de Artieda diseñó los diferentes espacios dramáticos por los que transcurre la acción de su única pieza teatral conocida: Los amantes. Compuesta poco después de 1577, se trata de una obra deudora de los parámetros dramatúrgicos de su tiempo, pues el componente literario del texto dramático predomina claramente sobre el espectacular. Estamos ante un tipo de teatro fundamentado en la palabra y muy poco en lo visual.Sin embargo, ya se perciben en el texto ciertos rasgos de innegable modernidad, que es el asunto que me ha interesado a la hora de acercarme a él. Mi objetivo será demostrar el dinamismo con el que se producen los cambios de espacio dramático a lo largo de la trama argumental para subrayar que Rey de Artieda tenía ya asumidas algunas de las innovaciones que desembocarán en el teatro nacional español unas décadas más tarde.

La polémica acerca del hiyab como símbolo de identidad de la mujer musulmana ha irrumpido en nuestra sociedad occidental. Si bien visiblemente no es más que una prenda, el ocultamiento del cabello, el cuello, y en algunas ocasiones el rostro y el cuerpo hacen que su uso no deje indiferente y su significado exceda más allá de lo puramente religioso. El presente trabajo constará de dos partes: La primera, tratará de entender la naturaleza de esta prenda, estudiando su procedencia, sus tipos y el significado que para las mujeres musulmanas tiene portarlo. La segunda, se centrará en el debate público y político que en muchos países de Europa, entre ellos España, viene provocando su uso y las consecuencias que una eventual prohibición o limitación del mismo tendría.

The pottery found in the burials of El Cano is uniform in style to these made in the coclesanos valleys between 700 and 1000 AD. The coefficient of variability of the different pottery forms, evidence diverse standardizations values for polychrome and non-polychrome ceramics. Moreover, data of funerary contexts from the Cano recently excavated, suggest that elite has controlled ceramic production. This control over the production of certain goods reveals that these were important in the support or proper operational of the chiefdoms in Panama and mark the phase of splendour of this culture.
