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

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
I piccoli padiglioni universitari progettati da Enrico Mandolesi a Cagliari
No full textBetween 1962 and 1964, Enrico Mandolesi designed three small pavilions for the University of Cagliari: the Great Models Pavilion for the Institute of Construction 377 377 Antonello Sanna, Giuseppina Monni, Emanuela Quaquero I PICCOLI PADIGLIONI UNIVERSITARI PROGETTATI DA ENRICO MANDOLESI A CAGLIARI Science, the Pavilion for the Institute of Hydraulics and the Institute of Genetics. In all cases, the “pictorial” dimension, placing on the same level the warm tones of the clinker and the neutral one of the reinforced concrete, shows the author’s firm belief that all the materials have the same relevance. This is a lesson that Mandolesi learns from Mario Ridolfi, precursor of the Italian realism that abolishes the hierarchy between structural elements and finishes and declares that the creative idea of architecture lies in the precision of details. In the Great Models Pavilion for the Institute of Construction Science he chose to create a new volume connected to preexisting buildings with a small building. The horizontal and vertical windows declare the non-structural nature of the envelope made of bricks. A cultured design approach that uses the paradigm of the Illinois Institute of Technology by Mies van de Rohe. The Institute of Genetics is a building composed of two small volumes articulated on two levels and hinged to an independent stairway with a square plan. In this case, on a formal level, the basic principle is the horizontality that Mandolesi pursues at every level of detail. The author applied a combined solution that includes solid brick walls and a steel structure that connects to the frames of the fixtures. Both cases represent an accurate narration of construction stories that uses the combination of different materials, classic elements and modern solutions, the rough surfaces of reinforced concrete and the smooth ones of brick strips
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
