    Fluid silicone and biologic reactions. Clinical and experimental results

    No full text
    Una revisione della bibliografia mondiale, compiuta recentemente nel nostro Istituto ha posto in evidenza dati riconducibili a due grandi gruppi di ricerche: quelle sperimentali e quelle cliniche. I risultati che ne emergono sono complementari pur partendo da premesse e modalità di sperimentazione a volte anche profondamente diverse

    Long-term results of the treatment of cutaneous angiomas

    Dopo un breve inquadramento nosologico degli angiomi cutanei, gli AA. passano in rassegna i risultati a distanza dei diversi trattamenti in uso per le forme immature. Pur con le inevitabili sequele e limitazioni connesse con la particolare natura di queste forme patologiche, l’intervento chirurgico appare la terapia più idonea. L’ottimo andamento degli angiomi non sottoposti ad alcuna terapia porta in ogni caso a suggerire la massima cautela nella scelta di qualsiasi protocollo terapeutic

    The repair of the vermilion border with an orbicular musculocutaneous flap

    Tutti i tessuti del corpo possono essere, con vario sforzo ed in varia misura, estesi. Ciò è particolarmente possibile a livello delle labbra grazie alla loro estrema elasticità e senza alcun rischio per la vitalità dei tessuti mucocutaneo e muscolare riccamente vascolarizzati dalle arterie labiali (Boggio Robutti 1959, 1960). Seguendo questo principio è possibile allestire un lembo di muscolo orbicolare rivestito dal corrispondente tessuto cutaneo-mucoso del bordo rosa (Goldstein 1984, 1990). La sua elasticità ne consente un allungamento tale da ricostruire in modo ottimale perdite di sostanza del bordo labiale, sia superiore che inferiore

    Voltamperometric evaluation of postsurgical edema.

    The authors describe a simple voltamperometric arrangement to evaluate the hydroionic content of dermohypodermic tissues. This measurement exactly expresses the degree of edema in every site of the body and in all clinical conditions. Such an arrangement is particularly helpful with surgical patients, and can be used to judge the effectiveness of the so-called antiedematogenic drug

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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
