    Paesaggi dell'archeologia invisibile

    La riflessione contenuta in questo libro è maturata attraverso un tempo piuttosto lungo, ed è l’esito di un confronto tra punti di vista disciplinari e ruoli istituzionali diversi. Si tratta infatti di posizioni appartenenti ai variegati mondi dell’archeologia, dell’architettura e della progettazione del paesaggio, ma anche della topografia antica, della geoarcheologia, dell’urbanistica e dell’ecologia; si tratta inoltre delle competenze specifiche di un Dipartimento universitario (DiAP Diartimento di Architettura e Progetto – Sapienza, Università di Roma) e di una Soprintendenza archeologica (Soprintendenza Speciale per i Beni Archeologici di Roma – sede di Ostia), in rapporto con i Comuni di Roma e Fiumicino, con la Riserva Naturale Statale del Litorale Romano, con la Regione Lazio ecc.Il tema della ricerca presentata in questo libro è la messa a punto di “Linee guida per la valorizzazione dei rinvenimenti archeologici della direttrice archeologica-ambientale Roma-area costiera”, sinteticamente Linee guida per la valorizzazione dell’archeologia invisibile. Con archeologia invisibile si intendono i siti scavati a seguito di trasformazioni territoriali “inevitabili”, studiati, documentati e re-interrati per garantirne la conservazione. A volte si tratta di aree vincolate comprese all’interno di comparti edificati, o situate lungo le infrastrutture di collegamento, aree per le quali non si prevede esproprio né valorizzazione, che si presentano come tante altre porzioni di suolo incolto, intercluse o di margine, qualche volta recintate. La richiesta di usare queste aree, quando l’uso proposto sia coerente con le norme di tutela (con quanto cioè previsto dai vincoli diretti e indiretti, e comunque con la conservazione dei ritrovamenti) non può non essere presa in considerazione1. Purtuttavia queste aree non sono un “qualsiasi spazio verde incolto”, magari da attrezzare a giardinetto. E non è un banale problema di immagine: i contraddittori messaggi che queste aree mandano all’esterno hanno molto a che fare con l’incerta identità contemporanea di molti beni culturali, e con la pericolosa distanza che si sta creando tra società locali e patrimonio culturale, soprattutto rispetto ai beni di natura territoriale e paesaggistica.The observations contained in this volume, developed over a long period of time, result from a comparison of the points of view of various disciplines and institutions. The research theme presented in this volume is the definition of “Guidelines for the promotion and development of archaeological finds in the Rome-area archaeological and environmental coastal context” or, more succinctly, “Guidelines for the promotion and development of invisible archaeology”. By invisible archaeology, one means sites excavated following “inevitable” territorial changes that were then studied, documented and re-buried in order to guarantee their preservation. Sometimes, these are restricted sites found in built-up areas, or located along transport infrastructures, areas for which neither expropriation nor development are planned and which are like so many other areas of neglected, blocked or peripheral, sometimes enclosed, land. Requests to use these areas, when the proposed use is consistent with preservation regulations (that is, with what is provided for by direct and indirect restrictions, and in any case with the preservation of the finds), cannot not be taken into consideration. Nevertheless, these areas are not “just any overgrown green space”, perhaps to be set up as small public gardens. And it is not a mere issue of image: the contradictory messages that these areas convey to the outside world have much to do with the uncertain identity that characterises a great deal of cultural heritage today, and with the dangerous distance that is developing between local communities and cultural heritage, especially as regards land and landscape heritage

    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

    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

    Ortho-aminobenzonitriles 1 react with beta-ketoesters and alkyl malonates, in the presence of stoichiometric amounts of tin(IV) chloride, to give 4-aminoquinolines 2 and 4-amino-2-quinolones 3 respectively. Similarly beta-enaminonitriles 7 afford 4-aminopyridines 8 and 4-amino-2-pyridones 9

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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
