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
Trasferimenti tra coniugi, privi di corrispettivo, e giustificazione causale
No full textIl saggio indaga quale sia la causa negoziale dei trasferimenti senza corrispettivo che si compiano nell’àmbito della famiglia e, in particolare, tra i coniugi, specialmente quando abbiano ad oggetto beni immobili. Non di rado gli atti anzidetti possono prescindere dallo spirito di liberalità, perché sono compiuti in adempimento, per lo piú a titolo di datio in solutum, di ordinarie obbligazioni civili – le quali trovano fondamento, talvolta, proprio nel rapporto di coniugio – o di obbligazioni naturali, che il rapporto di coniugio pure è idoneo a far insorgere. Datosi conto del fatto che l’imputazione all’obbligazione naturale mette fuori gioco la ricorrenza di una liberalità, la disamina si preoccupa di verificare se, e in quale misura, la solidarietà familiare e coniugale si traduca nella sussistenza, a carico di ciascun coniuge (oltre che dei veri e propri obblighi imposti dalla legge in dipendenza del matrimonio), anche di un dovere morale, socialmente apprezzato, di rendere partecipe l’altro delle proprie sostanze e del proprio avanzamento economico.The essay investigates the cause of the negotiation of transfers without compensation that take place within the family and, in particular, between the spouses, especially when they relate to real estate. It is not uncommon for the above acts to be performed without the spirit of liberality, because they are performed in fulfilment, mostly by way of datio in solutum, of ordinary civil obligations – which, then, are sometimes based precisely on the marriage relationship – or
of natural obligations, which the marriage relationship is also capable of giving rise to. Given that the imputation to the natural obligation excludes the recurrence of a donation, the examination is concerned with verifying whether, and to what extent, family and conjugal solidarity is translated into subsistence, for each spouse (in addition to the real obligations imposed by law depending on the marriage), also of a moral duty, socially valued, to involve the other in his
or her own substances and economic progress
