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
La Certosa di San Cristoforo testimone di arte e architettura cartusiana in terra estense
No full textIl volume, esito di una lunga ricerca interdisciplinare, ricostruisce l'architettura certosina del monastero ferrarese dedicato a san Cristoforo, fondato da Borso d'Este nel 1452 e trasformato nel XIX secolo in cimitero comunale: la nuova funzione e immagine ottocentesca, che ha totalmente sovrascritto quella cenobitica, non ha del tutto cancellato le tracce dell'assetto e dell'architettura certosina. Sulla base dell'intreccio di molteplici fonti documentarie e di un lungo lavoro critico di lettura, interpolazione e interpretazione, alla luce della Regola certosina e delle esigenze da essa imposte alla costruzione delle case dell’Ordine, è stato possibile riproporre una coerente interpretazione dell'assetto cartusiano, mettendolo in relazione anche con le intenzioni del fondatore, con l'architettura ferrarese coeva e con quella di altre certose italiane, oltre che con l'interessante produzione pittorica e decorativa che per esso era stata prodotta
“Ne sono entusiasta io”. Lucia Lopresti e Bartolomeo Bonascia
No full textTra le molteplici ‘attribuzioni’ nelle quali la giovane Lucia Lopresti si cimenta scrivendo nel 1921 a Roberto Longhi, stupisce trovare il nome di Bartolomeo Bonascia accostato al ‘Crocifisso con un donatore’ del Museo di Castelvecchio a Verona, allora riferito ai Vivarini o a Jacopo Bellini. Solo in anni recenti il dipinto è stato di fatto ricondotto al seguito incontrato da Piero della Francesca a Modena, in un contesto entro il quale spicca appunto la ‘Pietà’ firmata e datata 1485 da Bartolomeo Bonascia (Modena, Galleria Estense). Anche se, a proposito del dipinto ora a Verona, risulta preferibile il riferimento a Cristoforo da Lendinara proposto da Carlo Volpe nel 1979, la lettura di Lucia Lopresti si rivela singolarmente calzante, oltre che animata da un sincero entusiasmo per l’allora misconosciuto artista modenese. Sorprende dunque che Longhi non abbia tenuto conto del suggerimento della fidanzata allorché, prima nel Piero della Francesca (1927) e poi nell’Officina ferrarese (1934), rivaluterà Bonascia come uno dei maggiori interpreti della lezione di Piero della Francesca in Emilia, insieme a Cristoforo e a Lorenzo da Lendinara.Among the multiple “attributions” to which the young Lucia
Lopresti applied herself when writing to Roberto Longhi in 1921, a
truly surprising appearance is the name of Bartolomeo Bonascia, which
she connected to a Crucifixion with a Donor in the Museo di
Castelvecchio, Verona, at that time ascribed to the Vivarini or to Jacopo
Bellini. Only in recent years has the painting been reassigned to a
follower of Piero della Francesca in Modena, precisely within the
context of the outstanding Pietà by Bartolomeo Bonascia, signed and
dated 1485 (Modena, Galleria Estense). Even if the painting in Verona
might be better considered as by Cristoforo da Lendinara, as proposed
by Carlo Volpe in 1979, Lopresti’s reading of it is particularly fitting,
as well as being inspired by sincere enthusiasm for the then unknown
Modenese artist. It is thus surprising that Longhi did not take his
fiancée’s suggestion into account, when — first in his Piero della
Francesca (1927) and later in the Officina ferrarese (1934) — he was
to reassess Bonascia as one of the major proponents of Piero’s legacy in
Emilia, together with Cristoforo and Lorenzo da Lendinara
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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
Get PDFThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
Acute Radial Head Resection for Fracture: are We Likely to Miss an Essex-Lopresti Injury?
No full textBackground. Given the current available evidence, surgical treatment of radial head fracture with acute resection is controversial. The aim of this study was to determine whether acute resection of the radial head for a radial head fracture leads to longitudinal forearm instability due to a missed Essex-Lopresti injury. Material and methods. A retrospective review was conducted of radial head resections performed for acute radial head fractures at two Level I trauma centers from 2000 to 2018. A total of 11 patients met inclusion criteria. Our primary outcome was a missed Essex-Lopresti injury at time of final clinical follow-up. Long-term telephone follow-up was attempted for QuickDASH, pain scores, and satisfaction scores. Results. Of the 11 radial head fractures in this study, intraoperative radial pull tests were performed and normal in 6 patients. No patient was found to have a missed Essex-Lopresti injury at a mean of 36.2 months’ clinical follow-up after radial head resection. At a mean telephone follow-up of 12.6 years in available patients, mean QuickDASH was 3.4, mean satisfaction was 9.75 out of 10, and no further complication or reoperation was reported. Conclusion. Our findings challenge the dogma that the radial head cannot be safely excised in the setting of acute fracture, even with elbow instability and/or wrist pain, particularly when intraoperative longitudinal stability is assessed by a stress maneuver
