Pietro Russo, A questa vertigine, Italic, Ancona 2016. [Recensione]
No full textA questa vertigine (Italic, Ancona 2016) è l’opera prima di Pietro Russo, poeta catanese, in cui l’autore, pur confrontandosi con la poesia del novecento, cerca nuove soluzioni stilistiche e di contenuto. I temi prevalenti sono l’incessante ri-cerca di un istante irripetibile nel fluire del tempo e la paternità.A questa vertigine (Italic, Ancona 2016) is the first work of Peter Russo, in which he while dealing with the poetry of the twentieth century, looking new stylistic solutions and content. The prevailing themes are relentless pursuit of an unrepeatable moment in the flow of time and the fatherhood

Preparation, Characterization, and Release Behavior ofNanocomposite Microparticles Based on Polystyrene andDifferent Layered Silicates
No full textA microparticulated, organic–inorganic hybrid system, useful as an active agent carrier, was successfully developed with an emulsification/solvent evaporation method. The system consisted of nanostructured polystyrene microparticles containing different silicates as nanosized fillers and benzophenone (BP) as a model active substance. The adopted preparation procedure gave high yields of microparticles, which displayed regular geometry and high encapsulation efficiency of the active agent. X-ray diffraction measurements showed that all of the hybrid systems had a polymer–silicate intercalated morphology and the BP was molecularly dispersed in the microspheres. Moreover, preliminary in vitro release tests evidenced that the inclusion of the nanodispersed silicates into the polymer matrix significantly modified the release behavior of BP, depending on the silicate type. Therefore, the nanocomposite microparticles are of great potential in the field of controlled release
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
Poly(buthylen terephthalate) based composites containing alumina whiskers: influence of filler functionalization on dielectric properties
No full textIn this research PBT-based nanocomposites, including various amounts (up to 10 wt%) of alumina whiskers have been prepared by using a Brabender internal chamber mixer and analysed in terms of dielectric properties
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
