    Il volume raccoglie gli atti del convegno “Conservare il digitale. Riflessioni su modelli archivistici, figure professionali e soluzioni applicative", svoltosi a Macerata il 7 e 8 maggio 2009, ideato e organizzato dal curatore dell’opera con l’intento promuovere una riflessione attenta e autorevole sui processi di archiviazione e conservazione dei documenti informatici, che prendesse in esame gli obiettivi istituzionali unitamente agli aspetti culturali e scientifici, ai profili applicativi e alle esperienze concrete. Il volume, pertanto, rappresenta un quadro ampio e articolato delle problematiche connesse ai processi di dematerializzazione e delle possibili strategie risolutive. Contributi di: G. Paci, G. M.

    I metadati nel ciclo di vita dell’archivio digitale e l’adozione del modello PREMIS nel contesto applicativo nazionale

    Piuttosto che presentare i profili applicativi standard in base alla classificazione funzionale classica (metadati descrittivi, strutturali, gestionali e di conservazione), alla luce anche della recente normativa nazionale sugli archivi e la conservazione digitale, in questo contributo si sottolinea il ruolo dei metadati nel ciclo di vita del sistema informativo aperto di archiviazione, considerando il modello nazionale imposto dall’emanazione recente delle regole tecniche, nel quadro dei modelli internazionali tra cui in particolare PREMIS. Si dedica inoltre un breve approfondimento alle delicate problematiche riguardanti la qualità dei metadati, agli identificativi univoci e alla granularità dell’informazione

    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

    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
