Biomarkers nell’ Espettorato Indotto
No full textRecentemente, nei programmi di ricerca, un certo numero di ipotesi sono state avanzate sulle varie metodiche in grado di valutare e misurare biomarkers infiammatori. In particolar modo, negli ultimi decenni, sono state messe a punto metodiche meno invasive, rispetto ai gold standard per la misurazione dello stato di flogosi bronchiale, rappresentati dal BAL e dalle biopsie bronchiali, quali quelle dell'analisi dei gas esalati, dell'esalato condensato e dell'espettorato indotto. tra queste emerge, in particolare, l'analisi dell'espettorato indotto, metodica standardizzata e validata, che, per l'alto grado di sensibilità e non-invasività, ha assunto, nell'ultima decade, un ruolo sempre più centrale nel caratterizzare il profilo infiammatorio alla base delle più comuni patologie dell'apparato respiratorio, tra le quali: l'Asma, la BPCO e la tosse cronica. A questo proposito, evidenze scientifiche supportano la sua importanza nel fornire utili indicazioni sia nella diagnostica, migliorando la comprensione della patogenesi, sia nella gestione clinica. Pertanto, è lecito pensare che sia giunto il momento per tale metodica di uscire dal campo della ricerca per entrare a pieno titolo in quello della pratica clinica
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
Blurred Lines, Distinct Forces: The Evolving Practices of Italian TV Audiences in a Convergent Scenario
No full textThis chapter builds on the final results of a several-years-long qualitative research on Italian convergent television, mainly focusing on the different professional and cultural approaches to television and media convergence and on the changes in television viewers’ consumption habits and practices, following or reacting to broadcasters’ production strategies. An original “pyramid” model of “weak” and “strong” audience engagement is presented, to represent effectively the relationships between television shows and their audiences and the different possible practices. The model is also particularly effective in explaining the more recent trends inside the Italian scenario. These changes in viewing practices and in the interplay between broadcasters and audiences have been divided into four categories to offer a fluid and unstable yet accurate portrait of television convergent consumption
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
