Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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 PDFWe 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
The mural paintings of Ala di Stura (Piedmont, Italy): a hidden treasure investigated
No full textIn the small mountain hamlet of Ala di Stura (Piedmont, Lanzo Valleys), a large but relatively unknown artistic heritage is
present, made of 110 mural paintings divided among meridians and paintings with religious themes. These artworks are
datable among XVI and XXI century. To support the work of touristic promotion carried out by the Commune of Ala di Stura,
micro samples have been withdrawn from the most relevant artworks in order to execute Raman and scanning electron
microscopy with energy-dispersive X-ray (SEM-EDX) analysis and to have useful information concerning conservation,
dating and global knowledge on the artworks themselves that are little known outside Piedmont. Analyses allowed to elucidate
phenomena of chromatic alteration (changing of lead pigments), to individuate pigments acting as time markers (synthetic
ultramarine blue, arsenical green pigments) and to have information on the origin and exploitation of pictorial materials used
by the artists who worked in Ala di Stura. Of particular interest is the fact that all pigments identified in the older paintings,
and many among those identified in the newer ones, could be derived from minerals sources present in the Lanzo Valleys,
among which is olivenite, a rare copper arsenate used as a green pigment that has rarely cited in the scientific literature
Le pitture murali di Ala di Stura (Piemonte): un tesoro nascosto
No full textNel piccolo villaggio montano di Ala di Stura (Piemonte, Valli di Lanzo) sono state censite 110 pitture murali divise tra affreschi con temi religiosi e meridiane. Le opere sono databili tra il XVI e il XXI secolo. Per supportare il lavoro di promozione turistica operato dal Comune di Ala di Stura, sono stati prelevati micro campioni dalle pitture più importanti sui quali eseguire analisi mediante spettroscopia Raman, in modo da avere informazioni utili per la conservazione, la datazione e la conoscenza globale delle opere stesse, poco conosciute al di fuori dell’ambito locale. Le analisi hanno permesso di chiarire fenomeni di alterazione cromatica (viraggio dei pigmenti di piombo), di individuare pigmenti che fungono da marcatori temporali (blu oltremare sintetico, verdi di arsenico) e di avere informazioni sull’origine e l’utilizzo dei materiali pittorici impiegati dagli artisti che hanno operato ad Ala di Stura. Di particolare interesse il fatto che quasi tutti i pigmenti impiegati sono riconducibili a minerali presenti nelle Valli di Lanzo, tra cui l’olivenite, un raro arseniato di rame utilizzato come pigmento verde
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
