La giustizia ambientale in Italia. Una riflessione introduttiva
Full text linkLa giustizia ambientale è un concetto non ancora del tutto condiviso in letteratura, nonostante una storia non proprio recente. L’indeterminatezza si deve probabilmente al fatto che esso si compone di altri concetti già complessi, come giustizia (sociale) e ambiente, per cui la possibilità di farne un principio ispiratore dell’agenda e della pratica politica dipende da come si sceglie di definirlo. Il contributo ha l’obiettivo di introdurre la discussione sulla utilità dello studio della giustizia ambientale in Italia nella convinzione che, pur con modalità diverse rispetto agli Stati Uniti, esso possa essere estremamente fruttuoso. Una sua migliore comprensione ed una verifica di contesto nel caso italiano potrebbero infatti contribuire sia allo sforzo complessivo di ridefinire il quadro teorico nel quale iscrivere il rapporto società/ambiente, di cui si sente il bisogno, in particolare in geografia, sia nel determinare l’evoluzione degli orientamenti politici e operativi
In search of spatial justice. Towards a conceptual and operative framework for the analysis of inter- and intra-urban inequalities using a geo-demographic approach. The case of Italy
Full text linkAlthough still needing a definite theoretical status, spatial justice represents an inspiring framework for geographical analysis and for planning. In this paper we try to operationalize the concept through a geo-demographic approach. By using demographic and social differences as proxy of the concept at the urban level we define five socio-territorial clusters based on the characteristics of the population residing in the enumeration area of 14 Italian local labour market areas (LLMAs) whose capital is also the capital of a metropolitan city. The first results of the analysis show a high level of heterogeneity and the absence of compact and segregated peripheries. At the same time the analysis highlights the need for further methodological investigations to attain a better representation of social justice in its spatial dimension

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
