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
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
Ferdinando Vistarini (1540/42-1576) e la Cappella della Purificazione in San Lorenzo a Lodi : committenza e memorie di famiglia
No full textFerdinando Vistarini (1540/42-1576), after the abandonment of the profession of arms, decided to take care of the ancestors’ memory, members of the most important family in the city of Lodi. Following the marriage of aunt Aurelia with count Giberto Borromeo, Ferdinando became a member of the familia of young cardinal Carlo (1560) and financed - with approval of Pio IV de' Medici - the construction of a church in the feud Zorlesco (Lodi), close to the villa family, to respect the last wishes of the father, the knight Asperando, died in 1554.
For the family chapel in the church of San Lorenzo in Lodi he commissioned, to the painter Bernardino Campi and the sculptor Antonio Abondio called Ascona, an altarpiece dedicated to the theme of piety of Christ and stucco figures of saints around the family crest in the center of the vaulted ceiling.
The publication of the article is an opportunity to present, in closing, some news related to the bust of Ludovico Vistarini (Lodi, Museo Civico), a valuable piece known only from 1977 and attributed by Susanna Zanuso to Angelo Marini, called Siciliano
L'altare di San Carlo per la chiesa del "Mezzano": un'aggiunta al catalogo di Stefano Lambri
No full textDodici telette del Chiaveghino per la "Scola del Rosario" in San Biagio di Codogno
No full textThis article pieces together the history of the decorations in the chapel of the Confraternity of the Rosary in the parish church of San Biagio in Codogno, founded in 1570. The members of the Confraternity spent a good deal of effort, time and money on decorating the chapel, which was completed in 1690 with a splendid Baroque scheme for the altar. Among the items from the early phase are the twelve small canvases with the Mysteries of the Rosary by Andrea Mainardi called II Chiaveghino, a Cremonese painter and pupil of Bernardino Campi, signed and dated 1601. The twelve paintings belong to a happy and prolific phase of Mainardi's career; as ivell as offering proof of the lessons learned from the Campi, they show an interest for naturalistic, everyday details derived from Northern Europe, and even glimpses of Moretto and Romanino. The latter may be put down to the influence of Luca Cattapane, with whom Mainardi worked in the Hieronymite abbey of Ospedaletto Lodigiano and the churches of San Domenico and San Pietro al Po in Cremona. The final work is the Assumption of Christ: the remaining three were either not done by Mainardi at all or else subsequently lost, so the series was completed - around 1625 - by Benedetto Marini from Urbino, who also painted the two large canvases of the Adoration of the Magi and the Slaughter of the Innocents in the vault
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
