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
Adaptive mesh refinement for hyperbolic systems based on third-order Compact WENO reconstruction
Full text linkIn this paper we generalise to non-uniform grids of quad-tree type the Compact WENO reconstruction of Levy et al. (SIAM J Sci Comput 22(2):656–672, 2000), thus obtaining a truly two-dimensional non-oscillatory third order reconstruction with a very compact stencil and that does not involve mesh-dependent coefficients. This latter characteristic is quite valuable for its use in h-adaptive numerical schemes, since in such schemes the coefficients that depend on the disposition and sizes of the neighbouring cells (and that are present in many existing WENO-like reconstructions) would need to be recomputed after every mesh adaption. In the second part of the paper we propose a third order h-adaptive scheme with the above-mentioned reconstruction, an explicit third order TVD Runge–Kutta scheme and the entropy production error indicator proposed by Puppo and Semplice (Commun Comput Phys 10(5):1132–1160, 2011). After devising some heuristics on the choice of the parameters controlling the mesh adaption, we demonstrate with many numerical tests that the scheme can compute numerical solution whose error decays as ⟨N⟩−3⟨N⟩−3, where ⟨N⟩⟨N⟩ is the average number of cells used during the computation, even in the presence of shock waves, by making a very effective use of h-adaptivity and the proposed third order reconstruction

No full textAppropriate 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
The Feshbach and Roe Affective Situation Test for Empathy revised and adapted for italian children.
No full textIn the past years empathy has been operationalized either in terms exclusively affective or in terms exclusively cognitive. on the contrary, many authors underline an integrate approach which takes into account both the affective response concordant with someone else’s emotion and the cognitive mediators that affect the empathic experience. The aim of the present study is to elaborate a picture-story index of empathy based on the integrated model above mentioned and addressed children from seven to eleven years old. Keeping the Feshbach and Roe as a prototype measure, we designed a series of story narratives in which the characters are described and portrayed in contexts that evoke sadness, happiness, fear, anger, pride, shame, jealousy. After reading each story a semi structured clinical interview is conducted. The data collected regards 100 children recruited from an elementary school of Palermo city. The scoring criterion in presented and the results are discussed
Designing a Method to Assess Empathy in Italian Children
No full textThis chapter opens with a review of the conceptual issues regarding empathy and its implications in measuring empathic responses. The elaboration of an empathic index for school-aged children is then presented. The index stems from the pioneering work of Feshbach and Roe (1968), who developed a series of story-narratives, the Feshbach and Roe Affective Situation Test for Empathy, considered a prototype in this field of inquiry. After describing how the FASTE is adapted to Italian children, some empirical findings are discussed which explore the consistency of the instrument and the relationships between empathy and other indicators of children’s social behavior such as aggressiveness, prosocial behavior and emotional instability
