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
La Germania di Hitler come «eresia protestante»
No full textIl saggio esamina, attraverso l’analisi di libri, riviste e giornali, le interpretazioni che i cattolici italiani diedero nel 1934-35 del nazismo, sottolineando la centralità assunta in esse dalla polemica antiprotestante. Spiegano questo fatto che potrebbe sembrare assai strano la perdurante tradizionale mentalità intransigente che spingeva a spiegare l’errore politico con quello religioso (e quindi teologico) e il livello molto acuto al quale la polemica antiprotestante era giunta in Italia in quegli anni. Soprattutto, questo modo di affrontare la questione permetteva di unificare le posizioni di quei cattolici che guardavano con qualche speranza alla crisi tedesca, confidando in una emendabilità del nazismo ed in un recupero cattolico nei confronti del secolare predominio protestante, e di quelli che insistevano sulla natura profondamente neopagana del nazismo e sul grave pericolo che esso rappresentava per la civiltà cristiana di tutta Europa. Le due posizioni potevano convergere in una battaglia essenzialmente politica: difendere e, semmai rafforzare, all’interno del regime fascista italiano, l’equilibro ormai raggiunto con la Chiesa cattolica; combattere ogni traccia di influenze pericolose che potessero venire in Italia dall’esperienza tedesca.The essay, which is based on the exam of books, journals and newspapers, examines the way in which the Italian Catholics interpreted German National-Socialism in 1934-1935, and shows the central role anti-protestant controversy had in it. This apparently strange fact may be explained both with the persistence of an old intransigent mentality that interpreted every political fault as a religious (theological) one and with the sharp level of the Catholic anti-protestant attacks of those years. But the main reason of this phenomenon is probably the fact that this perspective gave the opportunity of unifying those Catholics who were looking at the German crisis with some kind of hope, and who relied on an emendation of Nazism and on a Catholic recover from secular protestant predominance, and those who insisted on the utmost pagan nature of Nazism and on the danger it represented for the whole European Christian civilization. In this way the two attitudes could meet in the same political struggle: to defend, and possibly to enforce, the existing balance between Fascist regime and Catholic Church; to fight against every trace of dangerous influences coming into Italy from the German experience
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
