Effect of a new biostimulant made by Fabaceae tissues on ripening dynamics and must technological main parameters in Vitis vinifera cv. Ribolla Gialla
Full text linkBio stimulants are organic compounds that influence biochemical activity within the treated plant, increasing the efficiency of the whole plant or any of its parts, yet can increase the uptake of necessary nutrients. Yet, they are very safe for humans, animals, and environment; thus, their use decreases the pollution caused by chemicals. From this point of view, recently, great attention has been focused on the possibility of using natural and safe stimulants in viticulture, which is one of the most cultivated and remunerative crop worldwide. Furthermore, protein hydrolysates (PHs) bio stimulants are an important group of such products based on a mixture of peptides and amino acids, that have received increasing attention in the recent years due to their positive effects on crop performances. Hence, the aim of this work was to investigate the foliar application of a bio stimulant developed by Ilsa SPA. This product is characterized by the presence of amino acids and peptides along with the presence of triacontanol of natural origin (> 6 mg / kg), saponins and various polyphenolic compounds (tannins, flavonoids, chlorogenic; gallic and cafferico acids). All of these have a bio stimulating and antioxidant action, naturally present in the plants of the Fabaceae family and which, thanks to the enzymatic hydrolysis process, are effectively extracted and made available for the plants. Thus, it was tested in order to study its effect of on the yield components, technological maturity trend, and its effect on some must parameters interesting for winemaking. This study was conducted during the season 2021 in a private vineyard of Ribolla Gialla grapevine (Vitis vinifera, L.) grafted onto rootstock SO4, in the north-east of Italy, Friuli Venezia Giulia region. The vines were 15- year-old, cultivated at 1 x 2 m, grown in clay soil without artificial irrigation system. The trellis system adopted was a trained single Guyot. In this region, the climate is generally high rainy (about 1800 mm/year), hence for farmers and winemakers is of great interest anticipating harvest time, to avoid phytoiatric problems, especially for those variety, as Ribolla Gialla, that tend to reach the technological maturity later than other variety, without compromising any agronomic and oenological parameters. After one-studied year, the natural bio stimulant had a positive action. In fact, data showed that ripening was anticipated in the treated plants (TT), having had higher parameters at every stage than the not treated (NT). In addition, we report how the TT treatment reached a full maturity for local standards one week earlier than NT. Finally, there also was a good effect on must microbiome main components, since the Yeasts present in the must was higher in TT, meaning that the proteins in the bio stimulant promoted the growth of the microbial community of berry skin
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Triacontanol (long chain alcohol) Positively Enhances the Microbial Ecology of Berry Peel in Vitis vinifera cv. ‘Glera’
No full textkoamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
