Valutazione delle impurità solide in confetture mediante filth-test
No full textCinque diversi tipi di confettura extra e quattro
di marmellata per uso artigianale sono stati
esaminati usando la tecnica del filth-test secondo
il metodo stabilito dall’AOAC.
I risultati hanno mostrato che solo due dei 18
campioni di analisi sono stati completamente
puliti da diverse impurità solide. Le impurità sono
principalmente fibre tessili e frammenti di insetti.
Sono stati trovati inoltre peli di roditori, uova di
insetti e un acaro. La significatività dei risultati è

The andesitic ignimbrites from the Lower Permian volcanic sequence in the Val di Cave and Val di Fregio area (Trento, N Italy)
No full textThe Lower Permian volcanic sequence from the Val di Cave and Val di Fregio belongs to the southern sector of the Atesina platform. Rock types include andesites and dacites and rhyodacitic ignimbrites. The andesitic ignimbrites show widespread mineralogical and geochemical modifications due to syngenetic and post-eruptive interaction between rocks and low-temperature fluids. Andesitic magmas may have evolved towards dacitic terms through fractional crystallization of an assemblage dominated by plagioclase as it is supported by the mass-balance calculations. In contrast, the calculations rule out that the dacities could be the result of mixing between andesitic and silica-rich (rhyodacitic) magmas. -from Author

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
