Influence of Ovoli Typology on Globe Artichoke Development, Early Production and Head Atrophy: Preliminary Results
No full textIn the North-West of Sardinia (Italy) a two year experiment was carried out
during 1998 and 1999 to test ovoli dormancy and typology effect on the
development, early production and head atrophy of globe artichoke (Cynara
scolymus L.) cv "Spinoso sardo". Three different length periods of ovoli dormancy
were combined as main plots with the two main typologies of ovoli (ovoidi and
sigaroidi) as subplot in a split-plot experiment design with four replications. At the
end of the vegetative cycle, in late spring, dormancy of the mother plants was
induced in both years by diquat treatments on 15 May (D1), 30 May (D2) and 15
June (D3). Ovoli dormancy was broken by irrigation on 15 July 1998 and 3 July
1999. On 3 August 1998 and 28 July 1999, sixty plants per subplots (1.3 m x 0.70 m)
were transplanted in the open field at 3rd leaf stage.
All the early produced heads were harvested and measurements were taken
on head diameter, length and weight, stem weight and the number of productive
plants at the harvest. The length of the dormancy did not influence the early
productivity or the head atrophy while, in the second year of the trial, plants
obtained from over 2.5 cm diameter sigaroidi were characterized by the highest
number of leafs per plant and produced the highest number of heads when early
harvested and showed the lowest percentage of head atrophy on productive plant
basis

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
