No full textIndagini batteriologiche sul burro del commercio
No full textAccanto all'illustrazione di precedenti risultati ottenuti separatamente dai due AA, giunti alla conclusione che il burro del commercio in Italia presenta caratteristiche igienico-sanitarie scadenti, vengono esposti i risultati di un'indgine svolta a verificare l'efficienza igienica di un nuovo metodo di burrificazione, detto "continuo", nel corso del quale la crema viene burrificata senza venire mai toccata dalla mano dell'uomo, fattore quest'ultimo tra i principali della contaminazione secondaria. I risultati mostrano che, per quanto migliorabile, lo stato igienico del burro "continuio" è superiore a quello riscontratro per il burro di produzione normale. Vengono poi discussi gli indici batteriologici da utilizzarsi nel giudizio di salubrità del burro. Esclusa la carica batterica. influenzabile dall'aggiunta dei fermenti per la maturazione delle creme, i migliori indici rimangono il contenuto in miceti o quello in colonbatteri; limiti proposti: meno di 1000 miceti/cc e colonbatteri assenti in 01, c
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
Real time detection of driver attention: emerging solutions based on robust iconic classifiers and dictionary of poses
Full text linkReal time monitoring of driver attention by computer vision techniques is a key issue in the development of advanced driver assistance systems. While past work mostly focused on
structured feature-based approaches, characterized by high computational requirements, emerging technologies based on iconic classifiers recently proved to be good candidates
for the implementation of accurate and real-time solutions, characterized by simplicity and automatic fast training stages.
In this work the combined use of binary classifiers and iconic data reduction, based on Sanger neural networks, is proposed, detailing critical aspects related to the application of this approach to the specific problem of driving assistance. In particular it is investigated
the possibility of a simplified learning stage, based on a small dictionary of poses, that makes the system almost independent from the actual user.
On-board experiments demonstrate the effectiveness of the approach, even in case of noise and adverse light conditions. Moreover the system proved unexpected robustness
to various categories of users, including people with beard and eyeglasses. Temporal integration of classification results, together with a partial distinction among visual distraction and fatigue effects, make the proposed technology an excellent candidate for the exploration
of adaptive and user-centered applications in the automotive field
