Le protesi dentarie in infortunistica previdenziale: valutazione dei criteri di rinnovo e della scelta del materiale di confezionamento
Dopo un esame delle normative vigenti in tema di forniture e di rinnovi di protesi odontostomatologiche si sottolinea la opportunità di distinguere in tema di rinnovo tra revisione e sostituzione del manufatto protesico.
Entrambe possono richiedersi per: a) rottura parziale o totale o deterioramento della protesi; b) sopravvenute modificazioni delle condizioni dento parodontali, relativamente alle strutture di appoggio o di ancoraggio del manufatto; c) inadeguato ripristino funzionale a causa di errori di progettazione o di costruzione della protesi, anche in relazione al materiale impiegato.
Sia nella prima fornitura che nelle successive sostituzioni, le normative prevedono l’impiego di materiali in oro solo in casi tecnicamente indispensabili, trattandosi pur sempre di protesi da lavoro e non estetiche.
Viene auspicata l’utilizzazione di leghe auree da colata a basso contenuto prezioso in luogo di quelle tradizionali ad alto contenuto prezioso, tenuto conto degli ottimi risultati funzionali (ed anche estetici) e del costo certamente inferiore.
In fine vengono prospettate ipotesi sui tempi di rinnovo delle protesi odontostomatologiche

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
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
