Il futuro del diritto ambientale: il sogno dell’economia circolare
No full textL’articolo si propone di analizzare dal punto di vista giuridico il concetto di economia circolare. Si descrive l’evoluzione del concetto nel diritto europeo (settimo programma di azione ambientale; primo pacchetto sull’economia circolare del 2014; secondo pacchetto del 2015). Si propone l’idea che l’elemento caratterizzante dell’economia circolare sia quello di interconnessione o di sistema. Si provano a ricostruire secondo questa prospettiva le fasi dell’economia circolare in relazione alla produzione di prodotti di consumo (progettazione, specifiche tecniche; certificazione) e il ruolo del potere pubblico (incentivi, tasse e divieti). Si evidenzia che gli appalti verdi possano costituire un importante banco di prova per l’economia circolare

Competition and environment: conflict or confluence? Some reflections on sustainability agreements under article 101(3) of the TFEU
No full textThe article is based on an analysis of Article 101 of the Treaty on the Functioning of
the European Union (TFEU). This provision sets out the general rule of the prohibition of agreements between companies that may distort competition, with an exception for agreements that contribute to improving the production of products. The author, based on international and European provisions, proposes an interpretation of ‘production improvement’ also in an environmental sense. This interpretation could justify agreements between companies that, while contrary to the application of competition principles, move towards sustainable production (so-called sustainability agreements), even if they do not reflect the application of the competition principle. The competition principle emerges clearly in the Italian Environmental Code and is applied in waste regulation and Extended Producer Responsibility (EPR) systems. The author believes that this principle, on the one hand, is crucial to encourage sustainable production and economic efficiency but, on the other hand, should not be considered an absolute principle. Indeed, sustainable production requires exceptions to the principle itself, but only to the strict extent necessary
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
Concorrenza e ambiente: “conflitto” o “concorso”? Alcune riflessioni sui sustainability agreements di cui all’art. 101, par. 3 TFUE
Full text linkL’articolo prende spunto dall’analisi dell’art. 101 TFUE. Tale norma nel porre la regola generale del divieto degli accordi tra imprese che possono falsare il gioco della concorrenza prevede un’eccezione per quegli accordi che contribuiscono a migliorare la produzione di prodotti. L’A. richiama le norme di diritto internazionale e di diritto europeo che legittimano la lettura di tale miglioramento della produzione anche in senso ambientale. Tale lettura consente di confermare le interpretazioni che legittimano accordi tra imprese che, pur contrari all’applicazione dei principi concorrenziali, si muovono nella direzione della produzione sostenibile (cd. sustainability agreements). L’A. ritiene che il principio di concorrenza che emerge ormai chiaramente nel Testo Unico Ambientale (TUA) e che viene applicato nella regolazione dei rifiuti e nei sistemi di Responsabilità Estesa del Produttore (EPR), da una parte, sia determinante per incentivare la produzione sostenibile e l'efficienza economica ma, dall’altra, allo stesso tempo non debba essere considerato come principio assoluto. La produzione sostenibile porta, infatti, ad ammettere deroghe al principio stesso ma solo nella misura in cui sia strettamente necessario.The article is based on an analysis of Article 101 of the Treaty on the Functioning of the European Union (TFEU).

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
