    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    “Grandioso finestrone archiacuto a comparti, con magnifica vetrata quattrocentesca, dai meravigliosi smalti colorati. Sebbene molto restaurata, è una delle opere più insigni uscite dalle fornaci muranesi” (Grand compartmented ogival window, with magnificent fifteenth-century stained-glass, decorated with amazing coloured enamels. Even though much restored, it is one of the most eminent artworks produced in Murano furnaces). Such description given by Lorenzetti [1], sets the features of the Grande Vetrata of the SS. Giovanni e Paolo Church in Venice and above all, it considers every single part of which this marvellous work of art is constituted. These different parts are: the stone frame in which the stained-glass window is allocated, the stained-glass window itself (made up of 66 panels), and the grisaille used to decorate the glass tesserae. Looking at the precedent restoration works [2], it has been seen that the problem of the stone wall consolidation arose also in the past. Such a problem, however, was always considered second place as to the grisaille consolidation and to the image conservation. A close up analysis of the artefact was made and all the weathering phenomena were documented. The documentation was carried out for every constituent of the work of art (glass tesserae, metallic retaining structures and stone wall) and particular attention was given to their interactions (i.e. the consequences of the wall movement on the stained-glass window). The diagnostic work was conducted at different stages: characterization of the Building, Technological and Decorative Apparatus; analysis of their weathering and comparison of the data related to each apparatus. The restoration project will have to aim to the consolidation and integration of the grisailles, where it will be necessary, but the consolidation of the stone wall and the rectification of the panels’ deformation will not have to be relegated to the second place

    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

    Progetto di ricerca per lo studio degli scenari e dell'evoluzione di incendi nel complesso monumentale di Palazzo Reale di Venezia

    Lo studio della dinamica evolutiva di incendi in edifici storico-monumentali comporta l’analisi di tematiche più numerose e complesse di quelle che si affrontano adottando un tradizionale approccio prescrittivo, oppure un più nuovo approccio di tipo prestazionale alla sicurezza antincendio. Infatti, parallelamente agli obiettivi “classici” (esodo in sicurezza ed incolumità di persone e squadre di soccorso, resistenza e stabilità delle strutture per un tempo predeterminato), negli edifici storici occorre mirare anche alla salvaguardia degli edifici stessi nonché delle opere d’arte presenti al loro interno, cercando di limitare i danni che un incendio potrebbe causare tanto al contenente, quanto al contenuto. Per conseguire, quindi, gli obiettivi di sicurezza necessari, l’unica via alternativa ad un approccio prescrittivo (che nella maggior parte dei casi porterebbe a pesanti ed invasive modifiche estetico-strutturali) consiste nel ricorso alla Fire Safety Engineering (FSE), attraverso la schematizzazione e la modellazione di scenari d’incendio realistici, ritenuti particolarmente pericolosi per l’incolumità delle persone, per le strutture e per le opere d’arte presenti nell’edificio. Strumento prezioso per studiare gli aspetti legati all’evoluzione dell’incendio nell’ambito della FSE è la Computational Fluid Dynamics (CFD), che consente uno studio virtuale degli scenari di cui sopra. Oggetto della presente momoria è apponto una modellazione di questo tipo, riguardante il complesso monumentale di Palazzo Reale a Venezia, il cui valore storico-architettonico, unitamente alla ricchezza e all’importanza delle opere in esso contenute, ne fanno un patrimonio culturale di inestimabile valore

    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

    Protecting the historic centre of Venice. A coordinated analysis of the physical and perceived wear processes to define mitigating actions

    Full text link
    The research aims to identify "physical" and "perceptual" wear factors of the historic center of Venice (with particular attention to the effects of anthropogenic pressure related to the phenomenon of tourism) and to assess the damages they could produce to identify criteria and tools of mitigation and control. Research is part of the Action Plan "Protection and conservation of the heritage", established by the Plan of Management for the UNESCO Site of Venice and its Lagoon. Through a systemic reading and analysis of the forces of change in place, this study identifies the " macro-emergencies", i.e. the main factors that adversely affect the site’s safeguarding. The research project "Evaluation of wear processes and critical factors of the City of Venice and its lagoon, and its impact on the site’s protection" is part of the actions set out by the Management Plan of the UNESCO site of Venice and its Lagoon. The main objective of the project is the identification of physical and perceptual factors of wear, which threaten the conservation of the historical and artistic heritage of the historic center of Venice, with a particular focus on the effects of anthropogenic pressure linked to tourism, and the evaluation of their level of danger. A further objective is the recognition of measurable parameters (indicators) for monitoring and, subsequently, mitigation strategies for the most significant phenomena

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
