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
"Metodi e strumenti del progetto ambientale | Environmental Design Methods and Tools"
No full textIl delicato passaggio tra costruzione del complessivo impianto teorico-metodologico della ricerca PRIN - restituito nel primo volume - e sviluppo di quello operativo come quadro di riferimento per una sua efficace applicabilità nei contesti urbani - oggetto del presente volume - trova il suo focus più significativo nel momento della sperimentazione progettuale-dimostrativa, e nel modo in cui tale sperimentazione è stata condotta dalle unità operative di sede e dai gruppi di lavoro di expertise multiculturale e inter- (vedremo perfino infra-) disciplinare, anche internazionali, a queste connesse. Tale centrale momento della sperimentazione si fonda su alcune profonde consapevolezze, che hanno informato il modo stesso di svilupparla, e che quindi vale la pena ricordare: come l’attuale contesto della ricerca europea - nel suo sviluppo da un decennio a questa parte - individui l'ambiente costruito, e in particolare i distretti delle città, quale ambito preferenziale di sperimentazione per la transizione verso una società carbon-neutral e un'economia green e circular; come la recente programmazione della politica tecnica nazionale e internazionale individui nella rigenerazione delle aree urbane un volàno capace di determinare positive ricadute per uno sviluppo di effettiva lotta ai cambiamenti climatici e di sostenibilità ambientale, sociale ed economica; come la combinazione delle note ed evidenti criticità proprie delle periferie e delle aree di margine si accompagni a quello che sarà un tendenziale peggioramento delle condizioni climatiche in termini di isole di calore urbano, ondate di calore, pluvial flooding, fenomeni di siccità e aridità, aumento vertiginoso di ventosità estreme e devastanti; e come per tali contesti sia emersa in questi ultimi anni la inderogabile esigenza di una concreta sperimentazione progettuale sul campo, che possa indirizzare i processi di rigenerazione urbana verso obiettivi climate oriented di resilienza e di adattività, inquadrati nelle più vaste linee di sviluppo improntate sugli assi portanti ecologico, energetico e bioclimatico, e integrati con le strategie volte a migliorare gli aspetti di mitigazione, sicurezza, comfort, salute, uso razionale delle risorse.The delicate passage between the construction of the overall theoretical-methodological framework of the PRIN research – illustrated in the first volume - and the development of the operational context as a reference framework for its effective application in urban contexts - the subject of this volume - finds its most significant expression in the moment of the project-demonstration experimentation, and in the way this experimentation was conducted by the central operational units of the effort, together with the multicultural, interdisciplinary (and even ‘infra-disciplinary’, as shall be seen) workgroups, some of them international, that also contributed their expertise. This central moment of experimentation is based on some profound considerations underlying the very approach taken to the work, and which are therefore worth remembering: the way in which the current research in Europe identifies the built environment, and in particular city districts, as a preferential field of experimentation for the transition to a carbon-neutral society and a green and circular economy; how the recent planning of national and international technical policies identifies the regeneration of urban areas as a catalyst capable of having positive repercussions on the development of effective measures against climate change and environmental, social and economic sustainability; how the combination of the widely known and readily apparent problems of suburbs and fringe areas is accompanied by what will be a worsening trend in climatic conditions, in the form of urban heat islands, heat waves, pluvial flooding, drought and aridity, plus dramatic increases in extreme and devastating winds; and how these contexts, in recent years, have highlighted the imperative need for concrete design experimentation in the field, so as to channel the processes of urban regeneration towards objectives of climate-oriented resilience and adaptability, framing them as part of broader trends of development based on the axes of ecology, energy and bioclimatic factors, with the further addition of strategies to improve the aspects of mitigation, safety, comfort, health and rational use of resources
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
