Contribución al conocimiento del abejaruco común Merops apiaster en la provincia de Sevilla

Se describen en este estudio dos colonias de nidificación del abejaruco común Merops apiaster, situadas en diferentes zonas de la provincia de Sevilla. Para el estudio se hace una descripción de las zonas donde se localizan las dos colonias estudiadas y tarnbién se han definido una serie de variables respecto a la disposición y estructura de la galeria de nidificación: disposición del nido sobre el terreno, ejes horizontal y vertical de la galeria de nidificación, distancia horizontal y vertical entre galerias adyacentes, y longitud de la galeria de nidificación. Los resultados obtenidos muestran que la colonia 1 presenta una gran variabilidad en la distribución de las galerías de nidificación con una alta densidad de individuos. En el caso de la colonia 2, presenta homogeneidad en la distribución de las galeria de nidificación, con una baja densidad de población.In the present work, two colonies of bee eaters Merops apiaster, located in different zones of the province of Seviile, both on cliffs, have been described. A primary description of two areas of study is made and two sets of variables have been defined, one in regard to nest relative position -vertical and horizontal distance between adjacent galleries, and in relation to ground levels- and the other related to the structure of the nesting gailery -horizontal and vertical axes, and length. Results showed the colony by river Guadiamar presents high values both variability in the distribution of nesting holes and population density. The colony by river Guadalquivir presents homogeneity in the distribution of nesting holes and low population density

Keeping it liminal. The Mondiali Antirazzisti (Anti-racist World Cup) as a multifocal interaction ritual

© 2013 Taylor & Francis. This paper examines how social mixing and celebration of diversity can be enabled through sports festivals marked by their carnivalesque atmosphere. Our analysis draws on a longitudinal ethnographic study of the Mondiali Antirazzisti (Anti-racist World Cup), a non-competitive football tournament and intercultural festival featuring the yearly participation of hardcore football fans (ultras), migrant groups, third-sector associations and other informal groups. We consider how the multifocal ritual form of the event helps to create a liminal space in which discrimination and stereotypes can be temporarily challenged. The sources of collective effervescence are multiplied by placing sport games within a wider range of other leisure and cultural activities, thus promoting internal diversity and the inclusion of outsiders. Additionally, social boundaries are also blurred by not emphasising the competitive dimension of the sporting activities, making sporting categorisations more fluid, and breaking down the separation between protagonists and spectators. Nonetheless, considering the transient character of liminality, we also investigate problems and limitations implied by the pursuit of these objectives. It is concluded that, despite a certain degree of self-referentiality, the festival fosters the spreading of anti-discriminatory cultures by enhancing the participants’ reflexivity and feeding their commitment in generating spin-off activities in different local contexts

Language use, choice, maintenance, and ethnolinguistic vitality of Turkish speakers in France: intergenerational differences

International audienceThis paper presents the findings of research investigating first language maintenance and shift of Turkish speakers in France and the role of subjective ethnolinguistic vitality perceptions in that process. It examines the relationship between societalfactors and individuals' perception of the language contact situation as reflected in their speech behavior. The theoretical framework of the study is based on Giles et al.'s (1977) ethnolinguistic vitality theory. In fine with the mode/, a subjective ethnolinguistic vitality questionnaire, a language use-choice questionnaire, and a self-rating scale have been applied to 111 second-generation and 64 first-generation informants. The findings indicate intergenerational differences among Turkish immigrants with respect to ethnolinguistic vitality of the in- and out-groups, Turkish and French language use. Second-generation informants have more positive attitudes towards Turkish and also have higher vitality ratings for the in-group than the first-generation immigrants

Italian Scientists Abroad in Europe's Scientific Research Scenario: High skill migration as a resource for development in Italy

In recent years, the brain drain issue has gained such momentum that it has become necessary to adopt tools and methods to take a picture of a phenomenon that is, by its very nature, dynamic and changeable (Portes, 1976; Meyer, 2001; Ackers, 2005; Scott, 2015). This particular study focuses on clarifying the reasons why Italian scientists choose to look elsewhere for the best place to conduct their scientific research, and in what way their scientific experience abroad shapes the image of the Italian scientific system. A first exploratory analysis involving 83 in-depth interviews with Italian scientists (mathematicians, engineers and physicists) working in Europe was conducted based on qualitative and quantitative analytical methods, and the content emerging from these interviews was used for a systematic mapping of the situation that provided the foundations for our preparation of a second tool \u2013 a questionnaire \u2013 that was subsequently used to conduct a much more broad-based survey that involved 602 respondents. While our findings add complexity to existing theories on the brain drain and brain circulation, they also confirm the potential of highly skilled migration to improve the national development of Italian academic system
