La misura dell’ossido nitrico espirato: applicazioni cliniche
No full textRiassunto: La concentrazione frazionale di ossido nitrico nell’aria espirata (FENO) rispecchia il grado
d’infiamma-zione delle vie aeree, in particolare quella eosinofilica e, poiché non invasiva, la sua misurazione è
utile nell’in-quadramento clinico del bambino con sintomi respiratori ricorrenti. L’elevata sensibilità del FENO a
vari stimoli, in particolare a quelli allergenici o infettivi, cosi come alla terapia antiinfiammatoria, lo rendono
particolarmente utile nel monitoraggio del bambino asmatico con fenotipo eosinofilico. Nonostante siano
stati proposti valori soglia di FENO indicativi di presenza/assenza di infiammazione, la grande variabilità della
misura impone cautela nell’interpretazione dei risultati ottenuti dal singolo paziente. Il FENO, utilizzato come
complemento ai criteri clinici e funzionali, offre la possibilità di ottimizzare la gestione del bambino asmatico.
Ulteriori studi sono ne-cessari per stabilire l’utilità del biomarker in altre patologie respiratorie.
Parole chiave: Ossido nitrico espirato, infiammazione delle vie aeree, asma, atopia, bambini.Summary: The fractional concentration of exhaled nitric oxide (FENO) reflects the degree of airway
inflammation, especially that eosinophilic. Since non-invasive, its measurement is useful for clinical assessment
of children with recurrent respiratory symptoms. The high sensitivity of FENO to various stimuli, in particular
those allergenic or infectious, as well as to anti-inflammatory therapy, make it particularly useful in monitoring
the asthmatic child with eosinophilic phenotype. Although FENO threshold values as indicative of the
presence/absence of inflam-mation have been proposed, the great variability of its measurement requires
caution in interpreting the results obtained from the single patient. FENO, used as a complement to clinical and
functional criteria, could optimize the asthmatic child’s management. Further studies are needed to determine
the usefulness of this biomarker in other respiratory diseases
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
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
Tommaso Campanella on the Bible: Ontology, Epistemology and Political Philosophy
No full textIn Campanella’s philosophy, the Bible serves a variety of functions: it works as an ontological template (in which the notions of code and encoding play a crucial role), an epistemological canon (centred on the concept of historia as direct testimonium and demonstratio through the senses) and a heuristic outline of natural philosophical investigations (based on the mirroring of scripture and nature). It doesn’t come as too much of a surprise, therefore, if the great fault lines of Campanella’s metaphysics run through a philosophical landscape that is constantly punctuated by countless biblical references and reminiscences. The sacred book, which he knew from end to end, is the matrix of the inner book of his memory, whose power – trained by the celebrated Dominican arts of recollection – managed to build a monumental edifice that was in his mind before finding expression in his astounding feats of reading, writing and knowledge retrieval. Finally, the principal divisions of Campanella’s philosophical experience – prophecy, poetry and politics – are interwoven with narrative elements that derive directly from the staggering epic of salvation recounted in the holy book
