La sindrome del perineo discendente: patologia iatrogena o spontanea?
No full textAmong the causes of constipation, there is an infrequently recognised condition
called descending perineum syndrome. This pelvic floor dysfunction causes a
rectal tone disorder, and the clinical features include excessive and frequent
straining and incomplete evacuation. Electrophysiological studies have shown a
pelvic neuropathy in incontinent patients with descending perineum. The
aetiological agents have been identified as follows: greater parity, dystocias
and obstinate constipation, particularly if caused by expulsion difficulty. It
has been observed that pelvic floor surgery may have physiopathological
consequences that bring on the onset of dynamic disorders. The diagnosis may
present difficulties and failure to identify the syndrome leads to inadequate and
repetitive treatment of no real benefit to the patient. Since it is impossible to
correct the excessive descent of the pelvic floor, the treatment will be aimed at
resolving the predominant symptom in relation to the physiopathological factors
causing it
Malattie della mammella
No full textLe malattie della mammella, un tempo di esclusivo interesse chirurgico, vedono oggi l’intervento di un team multidisciplinare che deve essere in grado di affrontare al meglio tutte le problematiche senologiche, coordinando l'esperienza di più specialisti (radiologo, chirurgo senologo, chirurgo plastico, anatomopatologo, patologo clinico, oncologo, immunologo), ma tenendo anche conto degli importanti cambiamenti psicologici e psicosociali che qualunque trattamento per una patologia mammaria comporta, specie se si tratta di un cancro. In questo capitolo vengono descritte le principali malattie della mammella, con particolare attenzione alle neoplasie benigne e maligne, descrivendo le più recenti metodiche diagnostiche e terapeutiche, soprattutto non invasive, sia chirurgiche che complementari, farmacologiche (chemioterapia, ormonoterapia, immunoterapia, targeted thrapy) e radianti. Si tratta di un testo di 20 pagine, con 34 figure, 13 tabelle, 20 voci bibliografiche e numerosi richiami a specifici URL nel testo

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
