Verso un’epistemologia della pratica: ricerca e attivismo di progetto
No full textLa condizione di incomprensione tra i ruoli della cultura della progettazione e la
società che li contiene indica la necessità di rifondare la pratica e i suoi metodi. Ciò
può avvenire attraverso ridefinizioni scientifiche transdisciplinari con approcci di progetto
integrati e complessi. Funzione strategica ha l’educazione dei vari livelli della
committenza alla complessità dei processi trasformativi, per parteciparvi coscientemente.
Questi cambiamenti richiedono di riflettere su un’epistemologia della pratica fondata
su una speculazione teorica che accetti e coltivi incertezze e dubbi. Le direzioni indicate
sono la ricerca applicata alla professione e la proattività socialmente impegnata,
che l’accademia deve supportare con programmi dedicati di didattica e public
engagement.The condition of misunderstanding between the roles of design culture and the society that contains them points to the need to re-found practice and its methods. This can be done through transdisciplinary scientific redefinitions with integrated and complex project approaches. The education of the various levels of the clientele to the complexity of the transformative processes, has a strategic function to a conscious participation. These changes require reflection on an epistemology of practice based on theoretical speculation that accepts and cultivates uncertainties and doubts. The directions indicated are research applied to the profession and socially committed proactivity, which the academy must support with dedicated programs of teaching and public engagement
DIGITAL TRANSFORMATION OF THE AEC SECTOR: A SYSTEMIC INNOVATION OF PROCESSES AND STRUCTURES
No full textRating System come strumento di progetto per governare la complessità
No full textDa alcuni decenni le modalità di gestione dell’ambiente costruito sono radicalmente cambiate. La crisi economica, ambientale e l’acutizzarsi di alcune criticità sociali hanno introdotto fattori di indeterminatezza e imprevedibilità che hanno richiesto nuovi tipi di approccio al progetto. In questo quadro, i Rating System (RS) per la sostenibilità si sono gradualmente diffusi come strumenti progettuali, in alcuni casi incorporando principi di resilienza per rispondere efficacemente alle criticità del costruito, acute o croniche. Su queste basi, il contributo propone la formulazione di un RS per incrementare la resilienza degli insediamenti produttivi, asset fondamentale nella gestione del territorio. Il progetto diviene un protocollo aperto, flessibile e adattabile caso per caso
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
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
Tight Size-Degree Bounds for Sums-of-Squares Proofs
Full text linkWe exhibit families of 4-CNF formulas over n variables that have sums-of-squares (SOS) proofs of unsatisfiability of degree (a.k.a. rank) d but require SOS proofs of size n^Omega(d) for values of d = d(n) from constant all the way up to n^delta for some universal constant delta. This shows that the n^O(d) running time obtained by using the Lasserre semidefinite programming relaxations to find degree-d SOS proofs is optimal up to constant factors in the exponent. We establish this result by combining NP-reductions expressible as low-degree SOS derivations with the idea of relativizing CNF formulas in [Krajicek '04] and [Dantchev and Riis '03], and then applying a restriction argument as in [Atserias, Müller, and Oliva '13] and [Atserias, Lauria, and Nordstrom '14]. This yields a generic method of amplifying SOS degree lower bounds to size lower bounds, and also generalizes the approach in [ALN14] to obtain size lower bounds for the proof systems resolution, polynomial calculus, and Sherali-Adams from lower bounds on width, degree, and rank, respectively
