La discussione guidata come strategia didattica per imparare a pensare
No full textThis study tries to identify how teaching strategies that are based on guided discussion can affect some aspects of learning. A group of upper secondary school teachers used five guided discussion teaching methods. The techniques have been carried out within a class from September till December 2014. After each session, the pupils were asked to fill in a short questionnaire, focused on four learning dimensions: cognitive, metacognitive, social and emotional. The data analysis showed, on one hand, that the learning dimensions developed positively as the discussion strategies became more complex and, on the other hand, it underlined some difficult educational moments. This study shows how the guided discussion may represent an effective teaching strategy to develop meaningful learning for students and the professional development for teacher
Prefazione
No full textLa Prefazione mette in luce le finalità del volume che consistono nel proporre una valutazione critica - realizzata con un approccio interdisciplinare - dei contenuti, della concezione ideologica e della prospettiva universalistica della Dichiarazione Universale dei Diritti Umani del 1948.
La Prefazione sottolinea, da una parte, alcuni esempi drammatici di fallimento dei diritti umani, in particolare le violazioni dei diritti e dei bisogni dei minori; dall'altra, vengono evidenziati i nuovi ambiti problematici che impongono la necessità di precisare o di ampliare il significato dei diritti umani: dall'analisi del rapporto tra diritti umani e diritto alla migrazione e all'asilo, tra diritti umani e politiche di promozione dello sviluppo, tra diritti umani e diritto ad un ordine internazionale che consenta la piena affermazione dei diritti
Communication and interaction protocols for multi-agent systems in a framework based on C# and the Common Language Infrastructure
No full textThe aim of this paper is that of defining a protocol for interaction among agents. Such a protocol has been developed within an agent programming framework, including a model of agent and a communication system among agents, implementing that protocol. Moreover a new technological approach is proposed, different with respect to traditional agent programming frameworks which fully exploit benefits coming from object-oriented programming techniques, yet they suffer from some limitations imposed by such an implementation choice. Contrary to the widely adopted use of the Java platform in most agent-based solutions and related research activity, the present work has been entirely carried on in the novel .NET framework (Microsoft Corp.) which offers technological solutions able to cope with common problems which often arise when relying on different enterprise platforms (both J2EE and Microsoft DNA). In particular this work strongly benefits from the use of the C# language in the Common Language Infrastructure (CLI)
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
