Il tema del margine. Progetti urbani di Francesco Venezia a confronto.
No full textIl tema del margine rappresenta una questione centrale nel progetto urbano della città contemporanea: la crescente urbanizzazione ha prodotto infatti una serie di soluzioni di continuità sia tra parti di città differenti per carattere, sia tra città diffusa e campagna urbanizzata. Le dinamiche insediative degli ultimi cinquant’anni hanno infatti determinato l’insorgere di insoluti urbani, luoghi irrisolti dal carattere particolare, che richiedono tuttora, una risposta progettuale.
La ricerca individua quelle strategie in grado di attuare una mediazione fra elementi primari della città e margine urbano, interrogandosi se e in che misura la composizione, alla scala del progetto architettonico, sia ancora in grado di rispondere a questo ruolo, costruendo, come in passato, i luoghi dell’abitare umano.
Rifiutando l’idea di margine urbano inteso come limite, analizzando e confrontando tre progetti urbani di aree marginali dell’architetto Francesco Venezia, la tesi indaga il modo in cui essi siano in grado di dare risposte alla città contemporanea attraverso la ricerca della sua riconnessione con la tradizione e rafforzando l’idea che l’architettura scandisce e determina mutevolmente mutevole spazio e tempo trasferendo all’uomo nuovamente, all’interno dello spazio urbano, la consapevolezza di una rinnovata temporalità.
Il questa prospettiva, Francesco Venezia, applica nel comporre una poetica del progetto dove il tempo dell’ avvenenza, della sospensione guarda al passato mettendoci nelle condizione di immaginare un nuovo futuro.
Partendo da questi presupposti, la ricerca rileggere i progetti assumendo la compresenza di significati di natura diversa: il primo che identifica il limite come un dispositivo topologico che coincide con la cattura dello spazio, separando e collegando due realtà eterogenee, il secondo che intende il limite come manifestazione del luogo di soglia che emerge come zona posizionata instabilmente tra interno ed esterno, tra il dentro e il fuori.The theme of the margin represents a central issue in the urban design of the contemporary city: growing urbanization has in fact produced a series of solutions of continuity both between parts of the city that are different in character, and between the widespread city and the urbanized countryside. The settlement dynamics of the last fifty years have in fact determined the emergence of urban unsolved, unresolved places with a particular character, which still require a design response.
The research identifies those strategies capable of implementing a mediation between the primary elements of the city and the urban margin, questioning whether and to what extent the composition, at the scale of the architectural project, is still able to respond to this role, building, as in the past, the places of human living.
Rejecting the idea of urban margin intended as a limit, analyzing and comparing three urban projects of marginal areas by the architect Francesco Venezia, the thesis investigates how they are able to give answers to the contemporary city through the search for its reconnection with tradition and reinforcing the idea that architecture marks and determines mutable space and time by transferring to man again, within the urban space, the awareness of a renewed temporality.
In this perspective, Francesco Venezia, applies in composing a poetics of the project where the time of attractiveness, of suspension looks to the past putting us in the condition to imagine a new future.
Starting from these assumptions, the research rereads the projects assuming the coexistence of meanings of a different nature: the first that identifies the limit as a topological device that coincides with the capture of space, separating and connecting two heterogeneous realities, the second that intends the limit as a manifestation of the threshold place that emerges as an area positioned unstably between inside and outside, between the inside and the outside
Shedding Light on Peri-Urban Ecosystem Services Using Automated Content Analysis
Get PDFThe objective of this paper is to provide an overall perspective on peri-urban ecosystem services in European Countries. The phenomenon of urbanization affecting our era has seen the shift of the city from compact and well-defined structures to agglomerations with a seamless expansion. This has led to several environmental consequences that have affected the urbanized areas and the surroundings. The peri-urban areas may be the main urban design and planning challenge of the 21st century. These hybrid landscapes, characterized by high fragmentation, can be turned into opportunities to improve the sustainability and quality of urban areas, generating multiple economic, social and environmental benefits. Areas beyond the immediate urban core can be considered a zone of influence, which represent a critical resource in terms of provisioning, regulating, supporting services and cultural ecosystem services. Our study has been developed in the framework of the project “Fertile Lands, Fragile Lands” funded by the University of Catania. A multi-phased method has been applied, showing strong, heterogeneous ties between landscape and ecosystem services. While the importance of literature studies on this topic is well recognized, the same attention has not been placed on the tools and methods of conducting systematic and incremental literature reviews. Using Leximancer software, we propose a text mining approach to extract relevant themes and concepts as well as related topics of interest from identified literature on peri-urban ecosystems. We first introduce the overall methodology and then discuss each phase in detail. The outputs can be used as starting point for broad exploratory reviews and allow further exploration in this issue. The results show how the peri-urban space can be seen as a mosaic in which the settlement, the agricultural and the environmental systems interact and coexist, placing at the centre the relationship of reciprocity between the built environment and the open territory
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
