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
Note psicocriminologiche. La mafia tra antropologia criminale e psichiatria
No full textNella riflessione intorno all’oggetto “mafia” l’intreccio tra campi del sapere diversi è stato, e continua a essere, indispensabile. Le definizioni della mafia si sono infatti storicamente prodotte all’intersezione tra politica, società e diritto. Da quale prospettiva, dunque, antropologi e psichiatri hanno considerato il comportamento mafioso e l’appartenenza al sodalizio mafioso, specie in relazione alla dimensione associativa?Dall’età liberale al fascismo, la mafia è stata considerata alla stregua di una evidenza antropologica, determinata da ambiente e contesto, se non da “atavismo”? O invece è stata considerata una manifestazione criminale, punibile in quanto tale, e nei tribunali si è fatto a meno delle categorie psico-antropologiche elaborate dalla scuola positiva?
Il saggio si focalizza sulla definizione del fenomeno mafioso e della “mafiosità” durante il fascismo, uno dei momenti in cui la “questione mafiosa” torna con forza nel discorso pubblico. In particolare, prende in considerazione il contributo di psichiatri-antropologi criminali della scuola siciliana durante il fascismo e nei primi anni del dopoguerra.From the liberal era to fascism, has the mafia been considered as anthropological evidence, determined by environment and context, if not by 'atavism'? Or was it considered a criminal manifestation, punishable as such, and did the courts dispense with the psycho-anthropological categories developed by the positive school? The essay focuses on the definition of the mafia phenomenon and 'mafiosità' during the fascist regime, one of the moments in which the 'mafia question' forcefully returned to public discourse. In particular, it considers the contribution of criminal psychiatrists-anthropologists of the Sicilian school during Fascism and in the early post-war years
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
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
Centrifuge modelling of thrust systems in the brittle crust: Role of frictional décollement geometry
No full textCentrifuge analogue modelling has provided significant insights into the evolution and architecture of fold and thrust systems. However, all previous works focused on the deformation of viscous and/or plastic layers, and did not analyze the development of structures in the brittle crust. In this work, we present the results of analogue centrifuge models reproducing compression of purely brittle upper crustal layers. We run enhanced gravity models investigating the role exerted by frictional décollements on the evolution and architecture of thrusting and compared the results with new normal-gravity models with similar set-up. In line with the results of previous experimental works, our models show that the presence of a low-friction basal décollement significantly influences the evolution and pattern of thrust systems. By reducing the basal friction of the experimental wedge or the sector of the wedge where the low-friction décollement is located, this layer promotes experimental wedges with low tapers and low heights in the inner portion. Moreover, when a low-friction basal décollement occurs, the tectonic wedge is characterized by an increase in wavelength of thrust sheets toward the foreland, compared to the purely brittle models. Results show a good comparison between centrifuge and normal gravity models, indicating that the centrifuge technique can be successfully used to model shortening in the brittle crust and therefore to analyze the evolution and architecture of thrust systems
