Atelier 2. Progetti urbani, mobilità sostenibile e mercato immobiliare. Introduzione
No full textIl titolo dell’Atelier allude a tre “dimensioni” della trasformazione, tanto complesse quanto articolate, che si collocano su livelli differenti:
- i modi d’intervento sugli spazi e sulle forme di organizzazione dei territori urbani e delle attività che in essi hanno luogo;
- la riscrittura dei modelli di città, degli stili di vita e delle condizioni di abitabilità;
- il ruolo che le logiche di natura economica giocano nella costruzione dei rapporti tra attori istituzionali e privati.
Da prospettive diverse, i contributi all’Atelier rileggono le relazioni tra questi livelli, proponendo una riflessione su due grandi famiglie di temi, strettamente interconnessi, che contribuiscono a indagare le ripercussioni dell’attuale crisi economica internazionale sulla produzione di politiche e progetti per la città contemporanea.
Il primo concerne le ragioni assunte al fine di giustificare azioni e opere pubbliche, con particolare riguardo alle argomentazioni che accompagnano la definizione di scenari di sviluppo e la sperimentazione di differenti opzioni procedurali con cui dare loro traduzione.
Il secondo attiene invece alle prospettive progettuali per la riqualificazione della città esistente che tali azioni e opere fanno intravvedere.
Sullo sfondo sta una riflessione, più generale e non sempre esplicita, sul senso del progetto urbanistico che, traguardato dal punto di vista dei rapporti tra economie e territorio, oggi fortemente oscilla tra posizioni limite neoliberaliste e neowelfariste
L'«Urbanistica» di Bernardo Secchi, laboratorio e condensatore di esperienze
No full textUn gruppo di allievi ricorda Bernardo Secchi e in particolare il suo periodo di direzione della rivista Urbanistica, ripercorrendo anni che hanno lasciato un segno profondo nella loro vite professionali e private. Il testo restituisce alcuni frammenti di una memoria, personale e collettiva, insieme a spezzoni di una riflessione più ampia, e oggi ancora prematura, che va certo sviluppata
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
Mobility management at Politecnico di Milano: New infrastructures and behavioural change
Full text linkTransportation has significant and long lasting economic, social and environmental impacts, making it one of the main challenges to be addressed by policy makers, public managers and scholars worldwide. For Universities, students and staff transportation represents one of the largest impacts on the environment and society, since in many cases it represent a noticeable share of urban traffic. A wide literature is available on the policies that support reducing car usage and improve the environmental and social sustainability of commuting to University. This paper presents the situation in the Politecnico di Milano, recorded through mobility surveys carried out in 2015 and 2017 to investigate the key issues and design possible solutions. The aim of this study is to share the set of actions and activities planned to improve the current mobility patterns of the Politecnico di Milano in favour of more sustainable means of transport. The main strategies will be the redesign of the campuses and the new infrastructure to be installed, together with the promotion of sustainable behaviours among the whole University population thanks to various activities in the framework of the ‘Città Studi Campus Sostenibile’ initiative. A special mention will be given to the ‘Vivi.Polimi’ project, which aims to improve the liveability of the Politecnico spaces, and which will give sustainable mobility a new impulse. Indeed, the planned measures include the reduction of the parking spaces inside the historical main campus while providing new infrastructure targeted at the promotion of alternative means of transport, like increasing the number of bike shelters to encourage active mobility or installing new charging stations for electric cars
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
