La decrescita come trasformazione socio-ecologica: ripoliticizzare la sostenibilità
No full textIn quest’articolo si sostiene che riconoscere e affrontare una delle cause profonde della crisi ambientale globale, l’ideologia e pratica della crescita economica, permetterebbe alla scienza della sostenibilità di dotarsi di una capacità di analisi più incisiva, per la ridefinizione del futuro sostenibile della Terra. Il paradigma della «crescita» viene considerato come un imperativo
indiscusso e un bisogno incontestato, e come tale preclude «il politico», ossia il terreno pubblico della contestazione, nel quale diversi immaginari dei possibili ordini socio-ecologici si confrontano e competono per la loro istituzionalizzazione simbolica e materiale. L’articolo presenta quindi il paradigma alternativo della decrescita, che ambisce a ripoliticizzare il dibattito sui rapporti tra sostenibilità, economia e società e ad elaborare una nuova visione di trasformazioni socio-ecologiche. Nata dall’incontro della critica ecologista e di quella culturalista dell’economia, la decrescita è il frutto di un connubio tra un movimento sociale ed un movimento accademico, in opposizione all’economicismo e alla mercificazione. L’approccio trasformativo mira a modificare gli attributi fondamentali di un sistema socio-ecologico, come la modalità di
produzione economica, le istituzioni politiche, le ideologie, norme sociali e la vita quotidiana. La decrescita si è focalizzata su una molteplicità di strategie per veicolare tale trasformazione: dall’attivismo antagonista alla costruzione di istituzioni alternative, alle «riforme non riformiste», da implementare simultaneamente su più livelli e scale

Atrial Remodeling in Pregnant Hypertensive Women: Comparison between Chronic and Gestational Hypertension
Full text linkObjectives: Left atrial (LA) enlargement is a common finding in hypertensive patients (pts), however little information is available on LA changes during pregnancy. The present study evaluated LA size and function in pregnant women with hypertension.Methods: Patients population included 30 women with chronic hypertension and 30 patients with gestational hypertension.A control group of 16 normotensive pregnant women was selected. Serial echocardiography was performed at 12 and 24 week of gestation in chronic hypertension and at 24 week in gestational hypertension and after delivery. LA diameters andvolumes were measured and compared. LA conduit volume, passive and active emptying volumes were calculated.Patients were divided in 2 groups according to max LAV Index > 32 ml/m2 at 24 week of gestation.Results: Patients with chronic hypertension showed higher LA diameters (42 ± 2.0 vs. 36.5 ± 1.8; p<0.001) and LA volumes (maximal volume 45.5 ± 4.0 vs. 38.1 ± 7.3; p<0.001) compared with patients with gestational hypertension. The median value of max LAVI was 32 + 6.2 ml/m2 in chronic and 26 + 5 ml/m2 in gestational hypertension (p<0.01). During follow-up patients with max LAVI > 32 ml/m2 had more clinical complications evaluated as increase of therapy, fluid retention that need diuretic and hospitalization.Conclusion: Patients with chronic hypertension showed a more marked increased of LA volumes compared to gestationalhypertension due to a remodeling of atrial shape as effect of chronic overload. Patients with more dilated LA volumes developed a greater number of clinical complications suggesting that a dilated LA could be a parameter of hemodynamic instability
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

Similarity and Competition in the Agri-Food Trade among European Mediterranean Countries
No full textUsing Eurostat and OECD data on agri-food exports, this article provides a picture of the evolution in the similarity between Italian and other European Mediterranean countries’ exports, before and after the recent financial crisis. Considering different indexes, the similarity is somewhat moderate and does not vary noticeably among the indexes when considering the EU-25 market. By contrast, a strong qualitative dissimilarity is recorded in the North American market. Overall, France and Spain appear more similar to Italy and likely to compete in the same agri-food market segments. The crisis seems associated to a slight modification of the exports structure
