La qualità dei nidi: il Quality Framework Europeo
No full textNegli ultimi 10 anni si è assistito ad una vera e propria svolta nelle politiche europee rivolte ai servizi per l’infanzia in quanto si è passati da un approccio meramente orientato all’espansione quantitativa dell’offerta , legato ad una concezione prevalentemente conciliativa, ad una nuova visione in cui si afferma convintamente il valore educativo delle istituzioni rivolte a bambini da 0 a 6 anni. In particolare, negli orientamenti normativi europei più recenti, emerge chiaramente come i servizi rivolti alla prima infanzia non siano più concepiti solamente come servizi volti a promuovere la conciliazione tra tempi di lavoro e tempi di cura per le famiglie, quanto piuttosto si ribadisce che nidi e scuole dell’infanzia debbano rispondere prioritariamente al diritto dei bambini e delle bambine – in quanto cittadini e cittadine europei – a ricevere educazione e cura adeguate a soddisfare i loro bisogni e a promuovere lo sviluppo delle loro potenzialità relazionali, cognitive e sociali (Pilastro Europeo dei Diritti Sociali, 2017). Inoltre, dal momento che il nido o la scuola dell’infanzia rappresentano il primo ambiente sociale che bambini e bambine frequentano al di fuori della famiglia, tali istituzioni educative devono farsi garanti del loro diritto a partecipare attivamente alla vita sociale e culturale delle comunità in cui vivono (Convenzione ONU sui diritti dell’infanzia, 1989; Carta dei diritti fondamentali dell’Unione Europea, 2016).
Al contempo, gli esiti di numerose ricerche nazionali e internazionali dimostrano come la frequenza del nido e della scuola dell’infanzia possa contribuire in modo determinante a favorire il pieno sviluppo delle potenzialità infantili sul piano cognitivo, relazionale e sociale, innescando così circoli virtuosi che promuovono il successo formativo di bambini e ragazzi sul lungo periodo, contrastando gli effetti di eventuali disuguaglianze di partenza (ECEA, 2009). Per questa ragione, nelle politiche europee, l’investimento in servizi per l’infanzia di qualità elevata è considerato prioritario sia per contrastare il fenomeno della povertà educativa, sia per prevenire l’insuccesso scolastico e il successivo abbandono dei percorsi formativi da parte degli alunni che provengono da contesti più fragili
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
Video-Assisted Thoracoscopic Monitoring of Laser Lead Extraction by Femoral Route
No full textA 72-year-old man with a dual-chamber implantable defibrillator was referred to our center for transvenous lead extraction because of pocket infection and presence of an abandoned lead. We decided to proceed with a video-assisted thoracoscopic approach because of patient history and documented complete occlusion of the right subclavian vein. During the use of excimer laser for persistent adhesions, the ventricular lead broke down at the level of cavoatrial junction. To successfully remove the remaining portion of lead, we decided to use the excimer laser by femoral route. A final angiography through the laser sheath showed the integrity of the myocardial wall. We report a case of laser-assisted transvenous lead extraction unconventionally performed by the femoral route. A preventive minimally invasive cardiac surgery was implemented to provide more safety in this high-risk procedure. This technique may avoid the need of a full sternotomy in case of major bleeding complications
