Infrastrutture e nuove ecologie territoriali
No full textStrade, ferrovie, elettrodotti e centrali elettriche, acquedotti, fognature, opere igieniche e sanitarie, costituiscono un complesso articolato di reti e installazioni che sostiene e connota in maniera decisiva la vita urbana nelle città e nei territori. Le infrastrutture realizzano la trasformazione della natura, rendono disponibili e mercificano la materia, le risorse, i luoghi. Concepiti per fornire servizi efficienti e universali e aderendo a modelli ingegneristici sofisticati, gli apparati tecno-scientifici delle infrastrutture precipitano sui territori e con essi interagiscono mediante soluzioni spesso standardizzate che tendono a semplificare o obliterare i contesti, altre volte a generare conflitti ed esclusione.
Contestualmente, le emergenze del nuovo regime climatico e le pervasive spinte della transizione ecologica a limitare il consumo di risorse e a promuovere usi e processi non estrattivi ed equi mettono in crisi, almeno sulla carta, il capitale fisso sociale che, con maggiore intensità a partire dal secolo breve, è stato via via depositato nei territori. Sotto la spinta del paradigma tecno-digitale della transizione e le sue soluzioni certificate ma anche per l’implementazione di soluzioni e progetti che interpretano posizioni radicali a bassa tecnologia e/o fortemente ancorati ai contesti, il complesso infrastrutturale si ibrida per includere soluzioni “post-rete”, “fuori-rete”, decentralizzate ma anche infrastrutture marchiate verdi e blu e basate sulla natura.
Quali misure e progetti di infrastruttura riescono a interpretare le nuove ecologie territoriali e a favorire forme diffuse di relazionalità tra materia vivente e non vivente? Quali politiche e opere infrastrutturali sono in grado di risocializzare la cultura tecnica e di rimando l’attuale apparato infrastrutturale? Come si possono operare scelte collettive sulla tecnologia alla base dell'infrastruttura? In che termini è plausibile ibridare le infrastrutture esistenti e concepirne di nuove per integrare i saperi radicati nei territori? A quali condizioni lo spazio tecnico dell’infrastruttura può essere declinato per divenire aperto al pubblico e non più nascosto o accessibile solo a pochi specialisti? In che modo le infrastrutture possono rendere intelligibile e direttamente operabile la trasformazione della natura per un pubblico ampio? Come realizzare infrastrutture in grado di interpretare la fluidità della materia e le diffuse condizioni di instabilità e incertezza
Les écueils du projet comme outils d'enquete sur l'histoire du notre futur et la compréhension de notre présent
No full textDiscutere non se il progetto ci fa capire e conoscere meglio il presente, ma come può farlo: questo ci sembra rilevante e ci interessa fare.
In quel “come” si nascondono alcune insidie: la complessità delle trasformazioni della città contemporanea, la pluralità di soggetti, saperi coinvolti, l’incertezza del tempo futuro, ma anche del passato e del presente. Con il testo seguente vorremmo provare a discutere ciò
Landscape elements as a basis for integrated water management
No full textWater scarcity and flooding associated to climate variability and poor water use efficiency affect the liveability of our cities and their water security in the long term. As advocated by the Integrated Water Management (IWM) model, a transition towards arrangements that, besides centralized water infrastructures, also include onsite and efficient organization of water flows is required. A Landscape Elements Water Management Strategy (LEWMS) has been outlined to immediately guide the exploration of potential source control solutions for the recurrent spatial elements of a given urban landscape (roofs, gardens, parks, etc.) and the result of their reiteration at the catchment level. In the LEWMS, spatial configurations, water flow patterns and stakeholder’s arrangements generated by the spread of different decentralized options are drawn up to allow their comparison. Tested in the Brussels-Capital Region (BCR), the analysed macro effects of micro- scale landscape-based practices are gaining the attention of the local institutions.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
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
A socio-natural standpoint to understand coproduction of water, energy and waste services
No full textThis introductory article of the special issue on ‘Geographies of water, energy and waste service coproduction’ explores the implications of coproducing these services in terms of both accessibility and environmental sustainability. According to a socio-natural standpoint, provision extent and resources metabolized by the services are equally regarded employing a threefold conceptual framework integrating actor/flow and area fields. A rich variety of service coproduction geographies in terms of actors involved, resources mobilized and urban spaces covered emerges. More importantly, coproduction of water, energy and waste services proves to leverage on both service accessibility and environmental sustainability of the related resources.SCOPUS: ar.jiiTSEinfo:eu-repo/semantics/publishe
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
Wasteland rehabilitation in rural landscape: a design project in the Verona plain
No full textThis contribution presents a design exploration for the rehabilitation of a dumpsite in the municipality of Isola Rizza, Verona (Italy). In the Verona plain. a former district of brick production left in its wake a cluster of water basins and wastelands that are today distinctive of the landscape and object of a territorial dispute among landowners. public administrations, and the local community. A project for the rehabilitation of one of those wastelands, converted into a dumpsite. has been recently developed. It considers the idea of re-organizing the circulation of waste materials and soil involved in the remediation to implement a public park. Although the project has been facing the little consideration given by local regulations to integrated design, it clearly shows the capacity of systemic design to tackle rehabilitation challenges while offering potential spaces integrated with the local ecological and slow mobility networks
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
