Genotipizzazione delle accessioni della collezione ‘Vitiarium’
Get PDFThe 231 accessions of the most famous grapevine collection in Tuscany, the ‘Vitiarium’, have been genotyped analysing the polymorphism of 14 SSR loci. The analysis reveal 130 varieties belong to 28 international and 30 Italian varieties, 30 Tuscan local varieties and 42 unique genotypes, exclusive of the ‘Vitiarium’. Several synonyms, homonyms and misnomer have been identified. All data will be uploaded in the Italian Vitis Database
Della Borra
No full textPer la prima volta questo vitigno è stato segnalato da Basso in Garfagnana (Basso, 1992) che lo ha introdotto nella collezione 'Vitiarium' dell'Agricola San Felice a Siena (Basso, 1993). Basso suggerisce che questo vitigno possa essere sinonimo del 'Montanino n. di cui al momento si sono perse le tracce.
Più recentemente il Della Borra è stato nuovamente censito in Garfagnana, genotipizzandolo e introducendolo in un apposito vigneto collezione in loco (D'Onofrio et al., 2015). Appare essere presente esclusivamente in Garfagnana, dove ha un distribuzione sporadica.
Non corrisponde a nessuno dei genotipi presenti nei vari database viticoli, e presenta delle relazioni di parentela di primo grado con 'Barbarossa toscana' ed 'Empano', entrambi vitigni diffusi in Toscana ma non esclusivi della Garfagnana, e il 'Rollo/Pagadebiti', vitigno individuato in Garfagnana ma diffuso anche in altre aree italiane (D'Onofrio et al., 2005). L’uva e’ dolce, di sapore neutro gradevole. Matura entro la fine di settembre
Farinella
No full textCon il nome di 'Farinella', come quello di 'Negrara', 'Negrera', 'Negretta' e 'Negruzzo', si indicano varietà con grappoli caratterizzati da pruina cerognola (Marzotto, 1925). Di Rovasenda () cita una “Farinella n.” di Pisa, e Basso (1992) ne recuperò una in Garfagnana ampelograficamente corrispondente a quella descritta dal Cavazza (), che la introdusse nella collezione 'Vitiarium' dell'Agricola San Felice. A questa corrisponde la recente Farinella nuovamente censita in Garfagnana (D'Onofrio et al., 2015). La 'Farinella nera' qui descritta al momento è sicuramente sporadicamente diffusa nella Lucchesia (in Garfagnana) e probabilmente anche nel Pisano. Le analisi con i profili microsatelliti hanno evidenaziato che non corrisponde a nessuno dei genotipi presenti nei vari database viticoli, e che presenta delle relazioni di parentela di primo grado con 'Canina bianca', 'Grisantina bianca', 'Nicola nera' e 'Ugillina bianca', tutti vitigni presenti esclusivamente in Garfagnana, e con il clone di Mammolo omologato in toscana diffuso in Garfagnana con il nome di 'Cojona'. Inoltre pare che incrociandosi spontaneamente con lo 'Sciaccarello nero', anch'esso presente in Garfagnana, anche se non autoctono di quest'area, ha dato origine al 'Nicola nero' precedentemente citato da Basso (1992) e autoctono della Garfagnana (D'Onofrio et al., 2015). Pertanto, si può supporre che la 'Farinella nera' qui descritta sia autoctona della Garfagnana (D'Onofrio et al., 2015). I grappoli raggingono la maturità agli inizi di ottoble (terza epoca) con una buona, ma non elevata, gradazione zuccherina, ma con poca acidità e tannicità, pertanto i vini in purezza rislutano si scarsa struttura
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
koamabayili/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
