A severe case of pear decline disease
No full textA recent severe outbreak of pear decline in a four month-old orchard in Northern Italy is reported. The symptom was seen since July 2019 in about 30% of the plants which increased to 80% by the end of the summer season. Molecular analyses confirmed the presence of the pear decline phytoplasma (16SrX-C), ‘Candidatus Phytoplasma pyri’ in symptomatic and asymptomatic leaf materials and also in the roots of the symptomatic plants. The infected plants belong to the cultivar Abate Fetel grafted to quince MA; considering the frequency of the symptom appearance after transplantation and its spread in the field it is very likely that the rootstock was already phytoplasma infected and contributed to the quick dissemination of the pathogen in the field that was also emphasized by the presence of low numbers of the pear decline phytoplasma insect vector Cacopsylla pyri. The orchard is under process of uprooting and will be replanted with phytoplasma-free tested materials
Phytoplasma presence in carrot seedlings
Full text linkPhytoplasmas are cell wall lacking bacteria, insect transmitted, and worldwide infecting carrots with severe epidemics. Molecular tests on up to 4-month-old carrot seedlings from phytoplasma-positive seed batches, carried out under insect proof conditions, indicated that in the early stages of the plant development, the phytoplasma-infected and not water-stressed plants are asymptomatic. The phytoplasma seed transmission could represent a dangerous source of infection
Diritto, o potenza rappresentativa, attraverso il pensiero di F. Carnelutti, S. Satta e G. Capograssi
No full textMuovendo dal confronto fra realtà giuridica e realtà artistica, il saggio ripercorre le linee fondamentali del pensiero di Carnelutti, Satta e Capograssi sul tema della ricerca dei principi generali dell’ordinamento. La capacità del diritto di rappresentare tali principi solleva gli interrogativi sul fine della scienza e sulla funzione del processo.Starting with a comparison between legal and artistic reality, this essay examines Carnelutti, Satta, and Capograssi’s perspectives on the quest for fundamental principles in the legal system. The law’s ability to represent such principles raises important questions about the purpose of legal science and the role of the trial
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
