La formazione degli insegnanti per una scuola comunità
No full textLa scuola oggi si trova nella condizione di dover ripensare il proprio ruolo e la propria funzione nella prospettiva di un rilancio della centralità dei temi educativi e formativi e di un rinnovato rapporto di comunità interno ed esterno alla scuola. L’idea di una scuola comunità, che si propone come contesto in cui l’impresa educativa viene costruita in termini di progetto ampio e comune fra tutti coloro che in essa e con essa interagiscono, sta sempre più affermandosi nel panorama nazionale e internazionale. Con riferimento particolare al modello di scuola comunità costruito da Sergiovanni nella realtà statunitense, viene delineata l’esperienza di ricerca-azione sviluppata nel contesto scolastico trevigiano e il percorso di formazione che ha coinvolto gli insegnanti delle scuole dell’infanzia nel percorso verso la costruzione di una scuola comunità
Le competenze verso il mondo del lavoro
No full textIl volume raccoglie una parte degli interventi relativi alla VII Biennale Internazionale della Didattica e considera le questioni relative al rapporto fra competenze e mondo del lavoro, con particolare riguardo alla formazione delle competenze nelle professioni educative e formative e alle forme di valutazione oggi in atto. I contributi sono raccolti in tre sezioni: la prima sezione affronta con criterio mirato le relazioni fra le competenze e la realtà lavorativa e professionale evidenziandone la complessità e la dialettica presente; la seconda sezione è dedicata ai temi della valutazione, validazione e riconoscimento delle competenze e delinea un quadro multireferenziale e integrato che deve accogliere apporti provenienti dal campo formale, non formale e informale; la terza sezione considera i nodi della formazione e valutazione delle competenze nell’ambito delle professioni educative

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
Beam-Sweeping Design Based on Nearest Users Position and Beam in 5G mmWave Networks
Full text linkThe beam sweeping procedure estimates the beamforming directions, or beams, to be used for downlink millimeter-wave cellular transmissions to an incoming user entering the cell. We propose three new approaches for the choice of the sequence by which beams are explored (the beam-search sequence), in order to reduce the average time to find the directions. The proposed methods exploit a) the correlation among angles of departure of the incoming user and its nearest, already connected user, and b) the position of both the incoming and its nearest user. For point a), the nearest-neighbor-beam search method starts from the beam of the nearest user, and then explores other beams, with directions progressively farther away (in the angular domain) from the first beam. In the beam-and-angle search, the beam-search sequence is optimized by exploiting the knowledge of both users' position and the nearest-user beam. We also propose the simplified beam-and-angle search, which still exploits the nearest-user information, although in a suboptimal and simpler fashion. Based on the channel model of the 3rd generation partnership project, we analytically design the optimal beam-and-angle search sequence. We assess the performance of the proposed solutions, in terms of their average discovery time, also in comparison with existing approaches
BILATERAL PANCOAST-SYNDROME IN A PATIENT WITH METACHRONOUS PRIMARY LUNG-CANCER
No full textA rare case of double Pancoast tumor in a patient with metachronous primary cancer of the lung was treated with irradiation and operation. Both tumors were managed with pulmonary wedge resection and excision of involved chest wall. Six years after the first operation the patient is doing well without pain and respiratory failure
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
