Il senso del consumo alla prova della crisi economica
No full textDi fronte alla crisi economica ci si interroga se i comportamenti di consumo siano destinati a mutare, a favore di stili di vita meno orientati allo spreco di risorse personali e ambientali. Il saggio argomenta come il consumo debba essere esaminato con categorie non solo economiche per coglierne il senso nella vita quotidiana e le ragioni di una sua evoluzione. In tale ottica può essere intereptata anche la tendenza ad una maggiore eticità del consumare che si manifesta nei più diversi ambiti di consumo, in particolare tra i giovani e le donne
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
Prevention des metastases hepatique dans le cancer du colon opere' radicalement.
No full textThe prognosis of colon cancer, after curative resection, is mainly related to the outcome of metastases, and especially of liver metastases. It is generally accepted that adjuvant medical therapy is important in order to prevent the incidence of metastatic recurrences. The aim of the present review is to analyse the conclusions of the main recent randomized trials assessing the comparative value of different adjuvant protocols. The results obtained using either systemic infusion, the classical one, or intraportal infusion, which is mainly designed to prevent liver metastases, are reported. On the basis of the review, we can conclude that : adjuvant chemotherapy using combined drugs (MF, MOF) did not prove to be more active than 5-FU alone. The beneficial action of a combined 5-FU + levamisole regimen has been clearly demonstrated for patients with a Dukes C tumour. According to a unique and limited trial, intraportal adjuvant therapy has been shown to be effective for patients with Dukes B tumours, but this remains to be confirmed. On the basis of the present data, new adjuvant programs using combined chemotherapeutic and immunotherapeutic coupounds, and combined systemic and loco-regional infusion, could be developed
