Sensory properties of 'Cabernet Sauvignon' wines as affected by rootstock and season
No full textCabernet Sauvignon wines have been described as ruby red colored and with a typical herbaceous flavour. The effect of the rootstock and the climatic factors on these characteristics have been known, and it is important to investigate how to manage rootstocks in order to optimize grape quality. Thus, the aim of this study was to estimate the effect of seven rootstocks (SO4, 420A, 3309 C, 161.49, Fercal, 1103P, Kober 5BB) on grape production and quality. A three-years trial was carried out in the DOC area "Colli Orientali del Friuli", north-eastern Italy. The rootstocks mainly affected productivity and little differences were observed in the quality parameters; in fact, 161.49, SO4 and 420A showed higher yields in comparison with Fercal and Kober 5BB, while little differences in sugars were assessed. The sensory analysis of the wines was performed during three years. Summarizing the results, 161.49 and 420A rootstocks have been judged as better by the panel, average scores have been reported for Fercal and Kober 5BB rootstocks, different evaluations have been obtained by SO4 and 1103P rootstocks in the three years. The factor year seems to have more influence on sensory analyses than the factor rootstock. The relationship between sugars and sensory scores did not reveal a significant correlation even when the different years were kept separate. Thus, it is clear that the quality of wines needs to be described both with chemical parameters and with sensory analysis
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
