No full textApple russeting: the contribution of surface conductance in the early fruit growth development stages
No full textBiophysical fruit growth depends on a balance among the vascular and transpiration flows which enter/exit the fruit via phloem, xylem, and through the epidermis. There is a lack of information about how russet could influence fruit growth in apples by affecting these mechanisms. Two apple cultivars “Renetta Grigia di Torriana” (RGT) and “Golden Delicious” (GD) were monitored in their first stage of development determining fruit surface conductance (gc), as well as fruit growth parameters as absolute growth rate (AGR) and relative growth rate (RGR). The gc and growth behaviors of the two cultivars were compared to outline if there was a different fruit development pattern, assuming RGT has a more spread russet on its skin while GD is russet-free. The fruit gc was significantly higher in RGT compared to GD, after the manifestation of russeting on the skin surface while daily AGR and RGR trends were relatively similar between the cultivars. Thus, the fruit growth pattern in the initial stage of development suggests that the presence of russet does not affect daily fruit quantitative growth, but it does influence the within-day pattern. Fruit with higher gc have higher transpiration and xylematic fluxes thus inducing in the diurnal growth pattern a greater fruit shrinkage during the day followed by a higher recovery enlargement at night. This suggests a cultivar-dependent contribution of the vascular fluxes within the day that may be a cause-effect of russet development. Besides, this knowledge can provide hints on how to optimize resource inputs to the orchard shifting from a species-base to a cultivar-base water/environment requirement
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
