Accessibilità di prossimità a Mykolaiv. Scenari per una città dei 15 minuti.
No full textCostruire scenari futuri per Mykolaiv può rappresentare uno sforzo catartico per ripensare la città più vivibile, vitale, inclusiva e sostenibile rispetto al passato. Per orientare questo percorso, l’articolo presenta i risultati dell’implementazione di un indice di accessibilità di prossimità (IAPI) per la costruzione di scenari post-conflitto pensati per traguardare una città della prossimità, sostenibile, inclusiva e resiliente

Abstract
BACKGROUND:
In the thrombolytic era, persistence of ST-segment elevation was considered a marker of left ventricular (LV) aneurysm. ST-segment elevation may still be found persistently raised after successful primary percutaneous coronary intervention (PCI). Echocardiographic correlates of this finding, however, are still poorly known.
METHODS AND RESULTS:
82 consecutive patients with first ST-segment elevation myocardial infarction and successful PCI were divided into patients with persistent ST-segment elevation at discharge (sum of ST >4 mm) (n = 33) and those without persistent ST-segment elevation (n = 49). Conventional and myocardial contrast echocardiography were performed at discharge and at 6 months. At discharge, LV aneurysm was more common in patients with persistent ST elevation (27% vs 8%, p<0.005). Similarly, the wall motion score index was higher (2.5 vs 2.0, p<0.005) and microvascular damage larger (2.3 vs 1.8, p<0.005) in patients with persistent ST-segment elevation. At 6 months' follow-up, LV volumes were similar in the two groups.
CONCLUSIONS:
After primary PCI, persistent ST-segment elevation is associated with LV aneurysm formation in 30% of cases, it is not associated with significantly larger LV dilatation but with larger microvascular damage and dysfunctioning risk area

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
New Metrics for Inclusive Accessibility by Proximity
No full textStrategies to promote accessibility by proximity are affecting several cities around the words, aiming at creating the conditions, through planning policies, to reduce the spatial and temporal intensities and environmental impacts of daily travels by providing accessible services and opportunities in physical proximity to the citizen. In these experiences, proximity is generally declined in “functional” terms, thus conceived as the physical spatio-temporal distance to essential daily services and opportunities. The chapter proposes to enrich this concept by combining a functional dimension of proximity, measured through an infrastructure-based approach, with a relational one, focused on the exchange of resources and collaboration spontaneously activated in a community, sharing specific accessibility-related needs, problems and mobility opportunities. Both functional and relational proximities are relevant and complementary for better understanding and measuring accessibility by proximity as a condition for a more sustainable, resilient and inclusive city. Based on this, the chapter introduces an index for measuring both the functional and the relational prox-imity, called Inclusive Accessibility by Proximity Index (IAPI), to support policy for promoting forms of accessibility by proximity through the improvement of active modes-based access to essential services. Through a concrete application of the IAPI in the city of Bologna (Italy) and Mykolaiv (Ukraine), the chapter discusses how the proposed index, characterized by a high level of spatial detail, context-sensitivity, and high transferability, can be usefully employed for ensuring equitable access to services and opportunities in very different and challenging spatial conditions

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
