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
Vaccinazione antivaiolosa d'emergenza in Serinus canaria (Aves) durante l'attività riproduttiva e approccio terapeutico con isoprinosina
No full textThe fowl pox is a severe and common viral disease of the canary birds. In the following report both cutaneous and respiratory
shapes from a Fife and Gloster canary breeding were observed. The disease was responsible of conjunctivitis, vesciculae
and pustulae all around the eyes and the beak; after, a distribution of the lesions as scabs on the toes was registered too. The
diagnosis was confirmed by viral isolation on CAM of chicken embryos; characteristic viral pox particles were identified from
scabs with electron microscope.
All the canary breeders (a total of 20 couples) were immunized using a commercial vaccine (Poulvac® canary pox FOI, Fort
Dodge Animal Health). The first group of 10 couples was also treated with Isoprinosine, while the other 10 couples were used
as control group. For each couple of both groups, the number of laid eggs, the number of fertilized eggs, the number of chicks
born and the number of chicks weaned were evaluated during the first (December-January) and second (February-March)
brood period. None of the canaries showed effects after vaccination and treatment with isoprinosine. The reproductive performances
and particularly the number of weaned chicks, improved significantly during the second brood period in both groups;
nevertheless the group treated with isoprinosine showed an higher number of weaned chicks
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
