    Mole: an open near real-time database-centric Earthworm subsystem

    No full text
    Mole is an open-source and cross-platform Earthworm subsystem made up of a MySQL database schema, an Earthworm module, and a web interface. Although it sprang from INGV requirements, Mole is as general-purpose as possible in order to provide a high-level communication layer to Earthworm. In this sense, Mole intends to be a starting point for the Earthworm community to fire up a development effort for a new “Open Interactive Earthworm”.Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome, Italy EPOS: European Plate Observing System ORFEUS: Observatories and Research Facilities for European Seismology VERCE: Virtual Earthquake and seismology Research Community in Europe e-science environment NERA: Network of European Research Infrastructures for Earthquake Risk Assessment and MitigationUnpublishedErice, Italy "Ettore Majorana" Foundation and Centre for Scientific Culture1.1.

    TESEO2: Turn the Eldest Seismograms into the Electronic Original Ones

    No full text
    Historical seismograms contain a rich harvest of information useful for the study of past earthquakes. This requires proper digitization of the analog records if modern analysis is sought. The digitization procedure usually involves the extraction of the sample sequence directly from the image and, successively, a correction mapping from the (x,y) image coordinates to the amplitude and time of the samples. We present here a different digitization approach that relies on an intermediate parametric vectorial representation of the seismogram trace using piecewise cubic Bezier curves. Our proposed workflow standardizes the historical seismograms vectorization process into various stages insuring proper quality control. We have developed a software for seismogram digitization/vectorization named Teseo2 within the Sismos project (Michelini et al., Eos, Vol. 86, No. 28, 12 July 2005). Teseo2 is a plug-in for GIMP - a multiplatform photo manipulation tool - that extends its functionalities for seismological studies. Teseo2 allows primarily for: - additional operations on the vectorized trace (i.e. resampling and alignment) - supervised vectorization algorithms (color weighted mean) - features of post-analysis of the trace (curvature correction, time realignment) - trace import/export in several formats (such as SAC, SVG, DXF, ASCII, Timemarks distances). In order to keep track of the stages and parameters of a seismogram vectorization, Teseo2 is able to write this information into the image saved in XCF format. Teseo2 is developed following the "Open-Source" philosophy and it is freely distributed under GPL license. Finally, it is cross-platform and the sources, the binaries for Linux, Windows and Mac OS X, are periodically provided on the Sismos web site.PublishedPalace Hotel, 2 New Montgomery St, San Francisco, California, USA3.1.

    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

    Get PDF
    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

    Dispelling the Myths Behind First-author Citation Counts

    Get PDF
    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
