Adaptation of some Cabernet-sauvignon clones to the environmental conditions of north-eastern italian growing areas
No full textIn order to evaluate the relationship between "genotype" and "terroir" in the cv. Cabemet-Sauvignon some vineyards with 5 common clonal selections, 4 of which selected in France (337, 338, 341 and 15) and the other one in Italy (R5), located in Friuli Venezia Giulia and Trentino Alto Adige regions (north-eastern Italy) were investigated. In all vineyards involved in this research, within the period between the beginning of ripening and harvest, several of the most significant both vegeto-productive parameters (number of sprouting buds, real fertility, yield per plant, clusters per plant, cluster weight, pruned wood weight and Ravaz index) and enological parameters (sugars, titratable acidity and pH) were investigated. Moreover Wricke index was used in order to taste the stability level of both viticultural and enological parameters to different environments under observation. These investigations show, within variety Cabernet-Sauvignon variability, some reactive genotypes to the environmental conditions like clone 15; on the contrary other clones (337 and 338) show more control of the enological parameters of the must than yield parameter

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
