Government policy and the migrant crisis in the Mediterranean and African arenas
No full textAs in previous years, so too in 2018 the migration question dominated the Italian political debate. The new ruling coalition announced a policy change based on the intransigent protection of maritime borders. Against the background of a decline in the number of migrants reaching Italy’s shores, the year saw the imposition of increasingly tight restrictions on the activities of the NGOs involved in search-and-rescue operations along the central Mediterranean route. The closure of Italy’s ports, besides having obvious humanitarian implications, led to the displacement of migration flows, with repercussions for other Mediterranean countries. At the same time, the thousands of repatriations that were promised by the Lega (League) during the election campaign did not materialise. Rather than focussing on the government’s strategy in the domestic sphere, this article examines the continuities and discontinuities in the policy of Italy’s new government concerning the international dimension of the migration question, and it does so by focussing on the Mediterranean and African arenas. Upon closer scrutiny, the new government coalition built its policy on already existing trends, beginning with restrictions on search-and-rescue activities at sea, and a higher-profile role for the interior minister (the League’s Matteo Salvini) in issues that had once fallen within the remit of the foreign ministry. At the same time, the choice in favour of unilateral intransigence and the display of open hostility vis-à-vis Western European governments, together with the refusal by the Visegrad countries to accommodate requests coming from Rome, were reflected in Italy’s growing isolation in Europe
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
Gli apporti originali e le invenzioni del lavoratore autonomo
Full text linkIl contributo analizza criticamente l'articolo 4 della legge n. 81/2017, in materia di diritti sulle invenzioni e sugli apporti originali del lavoratore autonomo. Vengono in particolare messi in luce i (pochi) profili innovativi della nuova disposizione e le aporie ancora esistenti nella materia
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
