Trasformazioni delle città contemporanee tra pubblico e privato. Centri commerciali tra gli agrumeti storici di Palermo
No full textIn the last fifty years the governance and the transformations of cities reflects the phase of “uncertainty” produced by the formation of a new frame of spatial planning practises. At the moment, the way of planning the urban and territorial transformations, and the different possibilities to realise a project, are regulated by new forms of relationships between public and private. If from one side, new forms of negotiated actions between public and private actors make possible a larger flexibility in the process of transformation, from the other side, the general vision defined by the plan is lost and the risk is to generate an irreversible process of transformation. This situation occurs especially in the most external areas in the cities where are concentrated the interventions of private initiative for the realisation of shopping malls. The present experiences in Italy show an increasing tendency to use private investments to activate projects of urban transformation and regeneration. But if the private initiative is the element to set processes of urban renewal, it is also very important to balance the private interests with the, possible, perspectives of development for the public actors.
In Italy, exist numerous urban contexts, as in Palermo, still characterized by a strong interrelation between city and territory. But the historical landscape tend to disappear, both for the, legal and illegal urban sprawl, both for the tendency to transform the agricultural areas and the ancient historical citrus groves into places to destine to the commerce. In Palermo, the recent events, connected to the realisation of two new shopping malls in historical agricultural areas, show the increasing tendency to read the green areas as neutral support on which is possible to put any type of commercial object.
In this sense, the paper intend to propose some reflections on the necessity to valorise the place identity in the peripheral areas where, as in the case of Palermo, the signs of a historical and cultural landscape, still remain. The paper intends to investigate the aspects related to the possibility to integrate the public interest with the logic of the private investments, also in the peripheral areas where it is necessary to guarantee urban quality departing from the recognition of the local identities
Il territorio e l'uso delle energie rinnovabili nella città
No full textIn Italia, secondo quanto riportato nell’Annuario dei Dati Ambientali del 2010, redatto a cura dell’Ispra, le emissioni di gas serra sono state in costante aumento a partire dal 1996 fino al 2004, per poi subire un’inversione di tendenza negli anni successivi con un -5,7% nel 2008 rispetto al 2004. Complessivamente le emissioni energetiche di gas serra nel 2008 sono cresciute del 8,2% rispetto al 1990. Inoltre, sulla base delle quantità di emissioni, l’Italia potrebbe non essere in grado di rispettare l’obiettivo di riduzione fissato per l’Italia dal Protocollo di Kyoto e dal burden sharing interno dell’Unione Europea (una riduzione del 6,5% tra il 2008 e il 2012, con riferimento ai livelli del 1990)

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
