Analisi del cammino di soggetti sani e patologici in ambiente acquatico: aspetti metodologici
No full textLo studio, in questo lavoro di tesi, prevede di capire quale sia il metodo per descrivere a livello quantitativo la cinematica intersegmentale di un soggetto in ambiente acquatico ed effettuare un confronto tra una popolazione di soggetti sani e una di soggetti patologici. Si creano quindi le fasce di normalità degli angoli articolari dei soggetti sani e ci si sovrappongono gli andamenti angolari dei soggetti patologici per capire quanto si distanzino da una situazione di normalitàope

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
Effect of Cerium codoping on Er : BaY2F8 crystals
No full textWe present the Erbium I-4(11/2) and I-4(13/2) complete polarized spectroscopic investigation on a series of Er3+, Ce3+: BaY2F8 single crystals as a function of Cerium concentration. The main results of room temperature lifetime investigation show that the I-4(13/2) lifetime reduces from 15.6 ms to 10 ms, the I-4(11/2) lifetime reduces from 8.3 ms to 0.2 ms and S-4(3/2) lifetime reduces from 420 to 110 mu s when adding 4% Ce-codoping. Moreover, in the same experimental conditions, the fluorescence intensity from I-4(13/2) increases by four times when adding 4% Ce, and the intensity of the 3 mu m I-4(11/2) -> I-4(13/2) transition becomes undetectable. The experimental data are interpreted with a rate equation model. The obtained results could be interesting in perspective of obtaining a low-threshold 1.5 mu m Er laser.

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
