Strategies for the conservation and reuse of 20th century neighbourhoods: limits and potentials
No full textIn which way the neighborhoods of modernism built in the first half of the 20th century – where were explored many themes covering issues of urban-planning, architecture and building techniques themselves − withstood the passage of time?
Decline; the need to adapt structures to the standards of comfort and housing expected by a new generation of inhabitants; on-going demolition; the small alterations continually being made to the structures – all these raise the question of how to protect this architectural heritage.
Precise in-depth knowledge of these structures should highlight their physical characteristics, the materials and building techniques that went into their construction, and – above all – the context within which they were designed and produced. This, together with careful evaluation of the nature and degree of their decay, is the necessary basis for making decisions with regard to their future. Part publicly part privately owned, these structures are of varying characteristics, but they form a heritage that was designed and planned within a unified framework and context, hence there has for some time been recognition that specific steps should be taken to protect them. Instead, the aim is to consider how inevitable and necessary transformations might be “governed” on the basis shared criteria, with full recognition of the need to safeguard both the architectural characteristics of individual housing units and the overall appearance of the area as a whole.
Very interesting could be to focus on the design/project and process to intervene on single buildings, with all their technical contents, goals and criteria
Sustainability and Heritage: a challenge for contemporary culture
No full textThe workshop that took place in Bucharest, on October 2011, was distinguished by an interesting temporal shift (from ancient to more recent history) and by a shift in scale: from the single object or sum of buildings to the integrated vision of them in a whole urban context. This change made them more sensitive to, and more capable of, multiple complex meanings and values. This choice allowed the participants, from various European countries, each with their own cultural heritage (and not exclusively based on the specific disciplines of conservation and restoration), to come together to design a large fresco with the crucial help of local professors. This fresco combines the particulars of some clearly defined themes (making reference to cultural value, identity and conservation of material) as well as some more blurry issues. This fresco has the advantage of being able to present itself as an articulated story; expressing reflections, proposals, actions and wide-ranging programmes that take note (where it was possible to develop such ideas in such a short period of time) of the complexity of the themes, problems and actors involved. The eassay aims to develop some reflections on relationship between sustainability and architectural heritage, innovation and conservation
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
