To Have Urban Sustainability, Citizens Must Be Given a Nudge
No full textThe concept of urban sustainability is complex and multidimensional, and it cannot be reduced to simple improvements in energy performance or the adoption of more efficient technical solutions. Furthermore, also cities are complex and interconnected systems, and the sustainability of a city depends on different factors, including urban population growth, technological innovation, economic issues, the unpredictability of climate and socioeconomic changes.
Despite the challenges, it is possible to improve urban sustainability through an integrated approach involving all actors, including citizens. Because the involvement of citizens in local decision-making processes contributes to creating a sense of belonging and responsibility towards the environment and society itself
Prosuming Public Space
Full text linkProsuming Public Space: the UNPark project illustrates the experience of the Urban Nudging Park research project, funded by the social responsibility program of the Politecnico di Milano through the competitive call Polisocial Award 2019. The book returns the complexity that characterised UNPark: a research by design project, in the wake of tactical urbanism, on the theme of the role that urban infrastructures could have in the regenerative processes of the in-between spaces.
Indeed, UNPark has been a transdisciplinarity effort which took shape through a temporary urban tactical intervention and a study about the possibility of transforming the current parking under the Serra - Monte Ceneri Overpass, in Milan, into a multifunctional space equipped for social activities, including street sports.
Prosuming Public Space: the UNPark project is a monographic book, with thematic chapters by the members of the work team, that proposes, in addition to recalling the research work phases, reflections on the city during the pandemic, on the co-design, on the multifunctional regeneration of the urban infrastructures, and about the needed transdisciplinarity in any urban design intervention
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
Post-pandemic trajectories of work in the city and public spaces
No full textDuring the Coronavirus emergency that we are still navigating (summer 2022), public space, despite having the quantitative capacity to withstand the impact of the pandemic, has not proven to have the flexibility needed to accommodate and put its new usage requirements in order. It is therefore essential to interject, as soon as possible, to bring elements of flexibility, organisation and optimisation to public space within the design of the city, which require the engagement of its citizens, above all in its management. This contribution identifies, through both pre and post-pandemic examples and international research, certain trajectories of work for the coming years, with regard to the need to define new standards for indoor and outdoor design and new models for activity in public spaces, in order to render them more practical and create the vision of the “15 minute city/neighbourhood”, as a possible healthcare facility to combat future episodes of infectious disease by way of the flexible and adaptive design of public space, in which multifunctional regeneration of infrastructure could have a more important role
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
SEMI,RAMI E RADICI: DAI TERRITORI FRAGILI A QUELLI FLESSIBILI. NUOVE IPOTESI DI INTERVENTI PER LA RIGENERAZIONE URBANA
No full textGrazie alla Rivoluzione industriale gli insediamenti antropici si sono sviluppati secondo gradi di autonomia crescente fino a rendere indipendente lo sviluppo degli insediamenti umani dalla disponibilità locale di risorse, smarcandosi così dal rapporto di sussistenza sinergica città/campagna (E. Sereni, 1961). Ciò è stato possibile grazie alla canalizzazione di flussi di energia e materia. Precedentemente invece gli insediamenti umani si sono sviluppati in luoghi in cui erano disponibili le risorse per il sostentamento delle comunità (acqua, materie prime, cibo). In epoche successive lo sviluppo urbano ha richiesto che ai servizi originali si affiancassero delleinfrastrutture quali strade, porti, mercati e magazzini per favorire la circolazione e la trasformazione delle merci (Calabi, 2005). Questa evoluzione, spinta dall’accelerazione improvvisa della Rivoluzione industriale, ha portato a sistemi sempre più rigidi e completamente dipendenti dai flussi canalizzati, in cui la loro interruzione - se non prontamente ripristinata - ha come effetto l’immediato collasso dei sistemi, con conseguente decadenza/abbandono degli insediamenti (Maffioletti, 2005). Per ridurre queste criticità sono state condotte, da un lato ricerche su soluzioni che rendessero gli edifici meno dipendenti dai flussi canalizzati, dall’altro soluzioni di canalizzazione più flessibili per il supporto degli insediamenti umani. Le ricerche “Un muro per ricominciare”, “Post it” e “SEED Italy” rappresentano tre diversi approcci a questi problemi: nel primo caso viene individuata una struttura di supporto/canalizzazione che rappresenta l’elemento fondante della costruzione - o ricostruzione - dell’insediamento, in questo caso un “muro”; nella seconda ricerca vengono invece progettate delle infrastrutture estremamente leggere e adattabili su cui è possibile appoggiare elementi costruiti, però largamente riconfigurabili; mentre infine, nel terzo caso, si definisce un sistema di supporto minimo alle abitazioni – un core tecnologico e strutturale - intorno al quale poter costruire involucri di forma e dimensione diversa integrati al costruito esistente. Il contributo approfondisce, grazie alle possibilità di riconfigurazione degli insediamenti, gli aspetti tecnologici e ambientali delle tre ricerche citate, in una logica di trasformazione dei territori da fragili a flessibili
