    La vulnerabilidad social es un fenómeno multidimensional basado en interacción de factores de naturaleza demográfica, socioeconómica y ambiental. Su manifestación espacial genera diferentes perfiles de vulnerabilidad y una amplia variabilidad de procesos espaciales resultantes. La identificación de patrones espaciales de vulnerabilidad es importante para apoyar la toma de decisiones territoriales encaminadas a reducir las desigualdades sociales, actuando a diferentes escalas temáticas y espaciales. En este trabajo se presenta el proceso cartográfico seguido para la elaboración de un mapa sobre vulnerabilidad social en España en el que se representa un índice sintético de vulnerabilidad social a escala de Zona Básica de Salud. Los resultados cartográficos permiten afirmar que la distribución espacial de la vulnerabilidad social no es homogénea y que existen perfiles específicos de vulnerabilidad. Estos perfiles se diferencian por el papel -protector o de riesgo- que ejercen indicadores sobre la estructura demográfica por sexo, edad y nacionalidad y el nivel socioeconómico de la población, según el territorio del que se trate

    Science fiction film productions have become a very powerful tool to predict and illustrate societal and territorial threats and, in particular, to visualise future urban models. It is common knowledge that cinema is a powerful instrument to spread and envisage how future cities might look like. Therefore, beyond being such a great source of entertainment, there is no denying that films allow us to create and disseminate not only the main theories and complex thoughts, but also the analysis of the most accessible ideological and philosophical trends. This paper, through a selection of film productions of this genre, makes visible the fruitful interrelations between urban geography and cinema. For this purpose, this study systematizes the image of urban models offered by science fiction, incorporating these contributions to a geo-prospective methodology, in which, in addition to a critical analysis of the present, it proposes reflections on possible futures of our societies and their urban models.: Las producciones cinematográficas de ciencia ficción son herramientas que pueden ayudar a preconizar y predecir o ilustrar las amenazas de las sociedades y de sus territorios y, particularmente, visualizar futuros modelos urbanos. El cine es un instrumento muy poderoso para difundir y vislumbrar cómo pueden ser las ciudades. Más allá de la evasión facilita la presentación de complejas reflexiones, teorías, utopías, sociedades, ideologías o filosofías. Este artículo, valiéndose de una selección de producciones cinematográficas de este género, visibiliza las fructíferas interrelaciones existentes entre la geografía urbana y el cine. Para ello, sistematiza la imagen de los modelos urbanos que ofrece la ciencia ficción, incorporando estas aportaciones a una metodología geoprospectiva, en la que además de plantear un análisis crítico del presente, se proponen reflexiones sobre posibles futuros de nuestras sociedades y sus modelos urbanos

    Social vulnerability is a multidimensional phenomenon based on the interaction of factors of a demographic, socio-economic and environmental nature. Its spatial manifestation generates different vulnerability profiles and a wide variability of resulting spatial processes. The identification of spatial patterns of vulnerability is important to support territorial decision-making aimed at reducing social inequalities, acting at different thematic and spatial scales. This paper presents the cartographic process followed for the elaboration of a map on social vulnerability in Spain in which a synthetic index of social vulnerability is represented at the scale of Basic Health Zone. The cartographic results show that the spatial distribution of social vulnerability is not homogeneous and that there are specific vulnerability profiles. These profiles are differentiated by the role -protective or risky- played by indicators on the demographic structure by sex, age and nationality and the socio-economic level of the population, depending on the territory in question.La vulnerabilidad social es un fenómeno multidimensional basado en interacción de factores de naturaleza demográfica, socioeconómica y ambiental.

    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

    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

    La zaragoza de los 15 minutos contada en mapas

    The development of many cities has been guided by the principles of petroleum urbanism, which have created urban areas primarily designed for motor vehicles, often neglecting the primary subject inhabiting them: people. The current challenges facing the modern city of the 21st century call into question the established urban system. Consequently, international programs such as the Sustainable Development Goals (SDGs) and the New Urban Agenda have been established, setting goals and initiatives to address these challenges. In this context, the concept of the “15-Minute City” emerged in Paris, proposed as an urban model to address the economic, environmental, and social issues of our time. This article examines Zaragoza’s situation regarding this chrono-urbanist model, analyzing three of its fundamental principles: the city must be compact, complex, and accessible, while also assessing citizen participation initiatives. The creation of a new index that combines these three urban indicators, along with the cartographic representation of the results, allows for the identification of the spatial distribution of this urban model in Zaragoza. Adapting the research in form and content to its StoryMap version has brought the results closer to a wider audience, revealing that Zaragoza is not entirely a 15-minute city, although there are areas where this model is observed. Therefore, it is necessary to analyze our cities to identify the lines of action that future comprehensive tactical urban planning should follow.El desarrollo de muchas ciudades se ha guiado bajo las líneas del urbanismo del petróleo, aquel que ha creado urbes para el vehículo rodado, olvidando al principal sujeto que la habita: las personas. Los actuales retos a los que se enfrenta la ciudad moderna del siglo XXI ponen en entredicho el sistema urbano prestablecido. Por ello, en la actualidad existen programas internaciones como los ODS o la Nueva Agenda Urbana con los que se fijan metas e iniciativas para alcanzarlas. En este contexto, nace en París el concepto de “Ciudad de 15 minutos”, postulada como modelo urbano con el que resolver las problemáticas económicas, ambientales y sociales de nuestro tiempo. El presente artículo estudia la situación de Zaragoza respecto a este modelo cronourbanista, analizando tres de sus principios fundamentales: la ciudad debe ser compacta, compleja y accesible; además de valorar iniciativas de participación ciudadana. La creación de un nuevo índice que asocia estos tres indicadores urbanos junto con la representación cartográfica de los resultados permite identificar la distribución espacial de este modelo urbano en Zaragoza. La adaptación de la investigación en forma y contenido a su versión StoryMap ha acercado los resultados a un amplio público. Dando a conocer el hecho de que no se trata de una ciudad de 15 minutos en su totalidad, si bien presenta zonas donde sí que se aprecia este modelo. Por tanto, resulta necesario analizar nuestras ciudades para identificar las líneas de acción que debe seguir el urbanismo táctico integral del futuro

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
