No full textIn-vivo confocal microscopy of the ocular surface : ocular allergy and dry eye
No full textPURPOSE OF REVIEW: To summarize recent studies on in-vivo confocal microscopy (IVCM) findings in ocular allergy and dry eye disease (DED), highlighting the role of IVCM in the advancement of knowledge of these diseases. RECENT FINDINGS: IVCM provided new data on ocular surface changes in both ocular allergy and DED. Corneal and conjunctival epithelial and inflammatory cells, corneal nerves, and Meibomian glands showed peculiar patterns of abnormalities, not easily discernable with current clinical exams in these two diseases and their subtypes. At present, small sample size of researches, and poor standardization and evidence of image analysis and interpretation are the most challenging issues. SUMMARY: Ocular allergy and DED are common and increasing healthcare problems, and need better understanding of pathogenesis and natural history, more reliable endpoints, and more tailored diagnostic and therapeutic approaches. IVCM allows quick, noninvasive, steady-state respectful examination of the ocular surface at cellular level to be performed and has potential to be used in the future as a biomarker and to contribute to optimize the tailored management of these diseases
Onicomicosi equina nell'italia settentrionale : indagine rivolta all'identificazione degli eziologici
No full textIl notevole interesse condiviso da medici veterinari e maniscalchi nei confronti delle patologie della linea bianca dello
zoccolo equino è da imputare al rilevante e costante aumento di casi manifestatosi negli ultimi decenni, sia nel
vecchio che nel nuovo continente, in animali di qualsiasi razza, sesso, età e disciplina sportiva. Approfondite
ricerche dimostrano che esiste uno stretto rapporto tra i funghi cheratinofilici e l’insorgenza della malattia. Sulla
scorta di questi studi, il termine “onicomicosi” viene oggi correntemente utilizzato per descrivere la natura
parassitaria fungina della patologia. Il lavoro da noi compiuto rappresenta un ulteriore sforzo finalizzato ad
identificare l’agente eziologico responsabile della malattia, fornendo nel contempo migliori tecniche di indagine
diagnostica per il corretto isolamento di funghi di importanza medico-veterinaria dallo zoccolo equino. Lo scopo
conclusivo di questa ricerca è quello di indagare sulla relazione esistente tra l’infestazione fungina dello zoccolo e
l’insorgenza della malattia, rivolgendo particolare attenzione a quei fattori predisponenti il cui controllo può essere
d’aiuto per ridurre l’incidenza della stessa
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
