No full textObjective: The aim of the investigation was to assess the effects on post-operative course after bladder papilloma resection of a technique for the written disclosure of traumatic events, in interaction with individual differences in alexithymia. Method: 40 Ss. were administered a general questionnaire and the Toronto Alexithymia Scale (TAS-20) the second day after admittance. 20 Ss. were asked to write for 3 days, 20 minutes a day, about their experience of being in hospital, following instructions developed by J.W. Pennebaker and co-workers. The post-operative course was assessed objectively by the duration of stay in hospital and subjectively by Ss. completing the Symptom Check List 90 (SCL 90) the day before leaving hospital. Results: Ss. who wrote stayed fewer days in hospital and showed lower SCL 90 scores. The same effect was shown by low alexithymia levels. Study of interactions showed that the effect of writing was apparent only in Ss. high in alexithymia, while Ss. low in alexithymia showed a favourable course independent of writing. Conclusions: Writing about one's thoughts and feelings about being in hospital for a surgical operation shows beneficial effects on post-operative course. This holds particularly true for high alexithymic Ss., who obtain through writing the same outcome as low alexithymic Ss

No full textIn un gruppo di pazienti in emodialisi periodica è stata valutata la funzione gustativa con metodica elettrogustometrica.
I soggetti sono stati studiati prima e dopo la dialisi.
I risultati ottenuti mostrano un decadimento della soglia rispetto ad un gruppo di controllo di soggetti sani, ed un miglioramento significativo della soglia nel periodo postdialitico.
Tale recupero non è persistente, ma già a 24 ore è comple- tamente perso. Il miglioramento postdialitico, secondo gli 4.4., dovrebbe essere verosimimente attribuito alla rimozione, anche se parziale, delle mediomolecole responsabili della neurotossicità uremica
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
