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
Antifungal susceptibility profiles of Candida isolates from a prospective survey of invasive fungal infections in Italian intensive care units
No full textThe antifungal susceptibility pattern of 302 Candida isolates collected during an Italian survey on invasive fungal infections in the intensive care setting was investigated. The results were correlated with some epidemiological data and compared to the antifungal profiles obtained in a previous survey. No resistance to echinocandins was detected. The overall resistance to fluconazole was 12.6%, to posaconazole 6%, and to voriconazole 7.1%. C. tropicalis and C. parapsilosis accounted for more than half of all fluconazole resistance. The decreased susceptibility to fluconazole is not uncommon (12.3%) and appears to be increasing, particularly among C. parapsilosis isolates from 2% in '90s to 25.8% in the present study. A routine antifungal susceptibility testing of this species is therefore recommended
A new approach to evaluate the leading hadronic corrections to the muon g-2
Full text linkWe propose a novel approach to determine the leading hadronic corrections to the muon g -2. It consists in a measurement of the effective electromagnetic coupling in the space-like region extracted from Bhabha scattering data. We argue that this new method may become feasible at flavor factories, resulting in an alternative determination potentially competitive with the accuracy of the present results obtained with the dispersive approach via time-like data
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

The second edition of the International Workshop on “Flavour changing and conserving processes” 2017 (FCCP2017) took place on September 7-9, 2017 in Anacapri, Capri Island, Italy. The Workshop was organized by the Physics Department of the University of Naples “Federico II” and by INFN (Istituto Nazionale di Fisica Nucleare) – Sezione di Napoli. The focus has still been continued on the physics of flavour changing and conserving processes, the involved scientific community has been that of experiments like g−2, Mu2e, MEG, Mu3e, COMET, but also that of the K and B meson physics. More than thirty talks were presented covering the theory status as well as the latest results of experiments in various Laboratories of the world. We wish to thank everybody who contributed to the success of the Workshop. The speakers did an excellent job in presenting the latest results and all participants contributed to the success of the Workshop. We look forward to the next edition FCCP2019 when new results are expected, from many sides, especially on the g-2 FRONT.
