Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
L’allegoria della vita e della morte secondo il Libro di Barlaam e Josaphat: piccola antologia iconografica
No full textL'antico Ospedale Spagnolo: riscoperta e restauri
No full textIl testo ripercorre, in forma necessariamente succinta benché articolata, le vicende che hanno concorso al restauro dell’Antico Ospedale Spagnolo nel Castello di Milano, divenuto dal 2015 sede museale della cosiddetta Pietà Rondanini di Michelangelo Buonarroti.
Già dagli anni Novanta erano infatti emerse opinioni differenti sul mantenimento della statua nella sede in cui era stata sistemata dal suo arrivo a Milano, durante lo sviluppo del progetto dei BBPR per un rinnovato polo museale, riaperto dopo la seconda guerra mondiale.
Nel frattempo, lo spostamento della Direzione delle Biblioteche Rionali di Milano in altra sede, alla fine degli anni Novanta, aveva liberato gli spazi che le ricerche intraprese in vista del loro restauro avevano fatto riscoprire come quelli occupati dall’Antico Ospedale Spagnolo, sulle cui volte è dipinta una versione antica e sintetica del Credo cristiano cattolico in dodici versetti, datata 1576.
Nell’orizzonte morale “ufficiale” della Lombardia spagnola al tempo di Filippo II e di Carlo Borromeo, il conforto religioso accompagnava così il destino dei soldati.
Studi storico archivistici, rilievi e campagne diagnostiche avviate nei primi anni del duemila hanno fondato i progetti via via predisposti con previsioni d’uso variate nel tempo, fino alla scelta definitiva, avvenuta a gara per i lavori già espletata, di approntare in questa parte di Castello la nuova sede per l’opera michelangiolesca. Decisione che ha fatto emergere, oltre che apprezzamenti, anche critiche e perplessità, e ciò in sé può essere considerato fattore positivo di compartecipazione e affezione al destino del polo museale milanese più noto, spesso però espresse senza piena conoscenza dei fatti via via succedutisi tra frenate e brusche accelerazioni. In questo capitolo essi vengono ripercorsi, mostrando gli aspetti e le ragioni anche tecniche che hanno condotto alle scelte progettuali e di cantiere, da parte di chi ha continuativamente seguito gli accadimenti e le opere di restauro
Variations on the Author
Full text link“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 linkWe 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 linkWe 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
The correlation between transperineal ultrasound assessment of the levator ani muscle and postpartum urinary incontinence
No full textAims: The primary aim of the present study was to assess the association between levator ani muscle (LAM) integrity and function on the one hand, and the risk of urinary incontinence (UI) on the other. A secondary objective was to assess the association between fundal pressure in the second stage of labor (Kristeller maneuver) and the risk of postpartum UI. Methods: In this prospective cohort study, women underwent a clinical and transperineal ultrasound examination at rest, at pelvic floor muscle contraction (PFMC), and at Valsalva maneuver 3–6 months after their first vaginal delivery. LAM avulsion and levator hiatal area (LHA) were evaluated. In addition, women were interviewed about the presence of UI, whether stress (SUI) or urgency (UUI). Results: Overall, data of 244 women were analyzed. SUI was reported in 50 (20.5%), while UUI was reported in 19 (7.8%) women. Women who reported SUI had a higher prevalence of LAM avulsion and less proportional reduction in LHA from rest to a maximum contraction in comparison to women with no SUI. Women who reported UUI had a greater LHA at rest, during contraction, and during maximal Valsalva in comparison to women without UUI. No significant association was found between the Kristeller maneuver and the incidence of any UI. Conclusion: Levator ani avulsion and less proportional reduction of LHA with PFMC appear to be associated with a higher risk of postpartum urinary stress incontinence
