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
Mecenatismo aristocratico e vita intellettuale: i Corsini a Roma, Firenze e Palermo nella prima metà del Settecento
No full textVariations 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

Influence de l'effectif et de la densité par cage sur les performances productives, la qualité bouchère et le comportament chez le lapin
No full textTo study the effect of the type of cage and stocking density on the performance and behaviour, 180 rabbits were bred from 35 to 80 d of age in 60 individual cages and 40 collective cages (3 rabbits/cage) at two densities (12 or 16 rabbits/m2). The rabbits kept in collective cages showed lower feed intake, final live weight (-3%), and transport losses. Besides, meat lightness and coking losses were higher as well as the diameter and fracture resistance of the tibia. The rearing at high density determined scarce effects, limited to a higher dressing percentage (58.7 vs 57.8%) and meat red index (a*). The rabbits were submitted twice to an open-field test at 44 and 65 d. In the second test rabbits kept in collective cages used less time for exploration and showed a higher frequency of urination than rabbits raised in single cages. Major differences were observed with age: from 44 to 65 days, rabbits showed an increased frequency of behavior indicating adaptation to the cage condition
