River bifurcation analysis by physical and numerical modeling
No full textIn the framework of a river regulation design of the Po River Delta ~Northern Italy!, a study on a large physical model of the bifurcation Po di Goro-Po di Venezia was conducted with the main objective of determining the discharge subdivision rate at the river node, in order to assess the inflow conditions in the Po di Goro River for flood risk analysis. In this context, a two-dimensional depth averaged numerical model was tested against measured values, with reference to the prototype. In this paper a comprehensive analysis and discussion of the results is reported in order to highlight the applicability of numerical models in comparison with physical ones in river engineering applications
A study of medieval illuminated manuscripts by means of portable Raman equipments
No full textThe pigments used in five important medieval illuminated manuscripts (Ms. Pal.6; Ms. Pal. 159; Ms. Pal.
212; Ms. Parm. 1650; Ms. Parm. 3063), all held in the Biblioteca Palatina in Parma (Italy), were analysed
in situ by portable micro-Raman instruments supplied by Renishaw and Horiba Jobin-Yvon. In spite of
a strong fluorescence background, different pigments were identified and important information on the
pigment palette used in the manuscript illumination, helpful to clarify the history of the artworks, was
obtained. Differences in the pigments used, suggesting late interventions, were found. In particular, an
addition was identified in theMs.Pal.212 manuscript (Bruges – 15th century), and late interventions were
found in the coat of arms of Barbara of Brandenburg in her breviary (Ms. Pal. 6). A different origin for
some rubrics and illumination was found in Ms. Parm. 3063, a 12th century Psalter, whereas common
palettes for the different artists were confirmed for Ms. Parm. 1650 and for Ms. Pal. 159
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
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
