Competencies vs. interculturalty. Student exchanges in the age of PISA
No full textThe paper tries to show how the impact of PISA unexpectedly extends to fields such as that of student mobility producing, inside an evolving school system such as the Italian, some interesting effects. The analysis is the result of field research trying to understand the attitude of Italian secondary school teachers about individual long term student exchanges. This attitude has been studied by observing how teachers act towards returnees, the assessment of competencies the latter have acquired abroad, being a central moment of this acting. Such assessment is problematic because the Italian system does not give clear rules on how to assess the knowledge and the competencies acquired abroad. Two case studies show how, in the void left by inadequate legislation on this topic, some teachers have drawn inspiration from the evaluation of competencies in the PISA tests
Effetto immediato della rimozione diCaulerpa racemosasullo zoobenthos dell'infralitorale superficiale roccioso di Porto Torres (Nord Sardegna)
Full text linkCaulerpa racemosa(Forsskål) J. Agardh è una specie lessepsiana altamente invasiva e le conoscenze sull'effetto della sua diffusione sui popolamenti zoobentonici in Mediterraneo sono molto scarse. Lo scopo di questo studio è quello di valutare l'effetto immediato della rimozione diC. racemosasui popolamenti zoobentonici dell'infralitorale superficiale roccioso. E' stato condotto un esperimento manipolativo in un sito prospiciente un'area urbanizzata del nord Sardegna (Porto Torres). Durante l'estate 2004 sono state scelte delle aree random di 20x20 cm, nelle qualiC. racemosaè stata rimossa, e delle aree di controllo. Successivamente (ad un giorno e ad un mese di distanza dopo la prima rimozione), sono stati raccolti campioni attraverso l'uso di cilindri di plastica (diametro 40 mm) e di un raschietto metallico. Il materiale è stato fissato in formalina e gli animali raccolti sono stati identificati e contati. Dall'analisi multivariata risulta che non vi è differenza significativa (ANOSIM p=39,4% R=0,004) tra l'abbondanza dei taxa raccolti nelle aree di rimozione e le aree di controllo in entrambi i tempi di campionamento. I risultati ottenuti, del tutto preliminari, sottolineano la necessità di approfondire le conoscenze sul risultato delle interazioni diC. racemosacon gli altri taxa presenti nell'area su una scala temporale più lunga
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
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
