    Las catástrofes naturales

    No full text
    Durante los últimos cuarenta años, la cantidad de víctimas por catástrofes naturales se ha quintuplicado en el mundo. El aumento incontrolado de la población, especialmente de la urbana, así como la situación socioeconómica, medioambiental y política de algunas regiones, son las principales causas de esta situación. El objetivo del presente trabajo es dar una idea de las principales cuestiones (teóricas, tipológicas, dimensionales y de costos) ligadas a dichas catástrofes, las cuales pueden estimular reflexiones, desde consideraciones de tipo teórico hasta aquellas más prácticas y operativas

    INTERNET Y TURISMO: LA CYBER LIGURIA

    Según recientes sondeos la demanda de turismo en ambientes naturales registra un fuerte aumento en Italia, así como en todos los países de la Unión Europea. Internet parece ser el vehículo principal para comunicar esta oferta, ya sea porque la casi totalidad de los canales usuales de información (folletos, revistas especializadas, guías, etc.) están todavía dominados por los destinos tradicionales, o porque los usuarios están particularmente motivados y por lo tanto buscan un modelo de información diferente. El presente artículo se centra en el estudio de la región de Liguria, donde a un turismo maduro de sol y playa se está acercando cada vez más una oferta protagonizada por el variado paisaje de media montaña y de montaña del interior

    In Genoa, during the last twenty years there have been several changes that have profoundly transformed the image of the town. Before this transformation Genoa was associated almost exclusively with its port, it was not perceived as a tourist city of artistic and cultural interest. Nowadays, however, Genoa entered the national network of urban tourism based on the artistic and cultural resources. This paper presents the results of a questionnaire distributed to the visitors of one of the most important exhibitions held in town, Euroflora 2011. The aim of the questionnaire was to find out if: 1) the respondents visit or were going to visit some touristic attractions of the town; 2) Genoa can be considered as a tourist destination, 3) the level of satisfaction was acceptable as touristic destination. Thanks to the questionnaire was also possible to get visitors opinions and suggestions according to improve the tourist fruition of Genoa

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
