TEMI E PROGETTI DI ARCHITETTURA NELLA CITTA’ AL TEMPO DELLA CRISI
No full textLa città comeluogo complesso e multiforme di relazioni, identità, conoscenze, consumi, conflitti e integrazioni, ma anche economie e forme di produzione di beni materiali e immateriali, continua ad essere illuogo privilegiato del nostro immaginario e dei nostri progetti.
È proprio sulla città e i suoi abitanti chela crisi si manifesta più duramente conla conseguente perdita di competitività e di attrattività. In questo ambito, è possibile affrontare il tema della crisi dell'architettura, sottraendolo a una interpretazione esclusivamente economica, solo se si è in grado
di conoscerela complessità attuale, richiamandol'attenzione, in Italia come altrove, verso modelli innovativi ispirati a principi di adattamento.
La debolezza delle politiche attuali, i tagli alla spesa pubblica su scala nazionale elocale,la privatizzazione dei beni comuni, il crescente consumo dei suoli, il sempre più diffuso degrado sociale,l'emergenza ambientale sono tutti fenomeni che, per quanto evidenti, invitano a riorientare i dispositivi di sviluppo della società, dell'architettura e dei prodotti verso nuovi modelli di sostenibilità segnati dall'esiguità delle risorse.
Il tema della crisi ha acquisito una straordinaria centralità nel progetto di architettura, gli esempi selezionati fra i progetti elaborati dagli studenti del Laborarorio V di progettazione architettonica e di Laurea L@bCity presentano alcune riflessioni sulla città al tempo della crisi e sull'architettura intesa come disciplina del sapere e dell'agire nella società.The theme of crisis has taken on a dominating central role in architectural projects. The examples chosen from the projects developedby the students of Architectural Design Studio V and Degree Laboratory L@bCity, present certain lines of thought regarding both the city at a time of crisis and architecture understood as a discipline of knowing and taking action in society. From this standpoint the results offer food for thought regarding the future of the European city, representing a critical reflection on the board panorama of open-ended questions relative to the state of the
contemporary project. The issues of re-use and re-cycling of waste-areas are tackled, with suggestions for new programs and activities with regard to infrastructure, energy supplies, and a solution to the conflict between apparently incompatible objects and subjects (aligning itself to the phenomenon of hybridization); this process is fully in agreement with research into the transformation of the contemporary architecture of the city at a time of crisis
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
Phenolic constituents and antioxidant activity of Wendita calysina leaves (burrito), a folk Paraguayan tea
No full textBurrito tea originates from the leaves of Wendita calysina, an indigenous Paraguayan plant, which is commonly consumed in South America and in Western countries. Phytochemical investigation of this species has led to the isolation of 14 constituents, among them 2 new flavanonols, dihydroquercetagetin (1) and 3,5,6,7,4‘-pentahydroxyflavanonol (2), in addition to several known methoxyflavones, methoxyflavonols, phenylethanoid glycosides, and benzoic acid derivatives (4−14). All structures were elucidated by ESI-MS and NMR spectroscopic methods. Quantitative determination of phenolic constituents from burrito water infusions has been performed by HPLC-UV-DAD. The total antioxidant activity of the tea was measured by the ABTS•+ radical cation decolorization and chemiluminescence (CL) assays and compared with the values of other commonly used herbal teas (green and black teas, mate, and rooibos)
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
