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
Instruments, methods, research and professional training initiatives for Cultural Heritage transmission to the future
No full textThe essay presents the results of researches and trainings carried out by the Working Group directed by Antonio
Pugliano in the context of the Laboratory of Architectural Restoration of the Architecture Department at "Roma Tre"
University, in accordance with relevant national Institutions responsible for the protection of the Cultural Heritage and
the practice of the Professions relating to Restoration projects (MiBAC-ICCD, MiBAC-SSBAR; PPC Architectural
Council). This activity arises from a range of experiences carried out in the recent years by the same group of studies,
under the direction of Paolo Marconi and the coordination of the undersigned, on the subject of database production
turned to the characterization of the architectures and the national urban sites with historical, artistic and
anthropological interest. First experience in this direction was, at the end of the 90’s, the production of Atlante dei
Centri Storici Italiani esposti al Rischio Sismico (“Atlas of Italian Historic Places exposed to the Seismic Risk”) and its
digitizing database, realized for the Premiership - National Seismic Service. In this occasion we have proceeded with
the development and the testing of a method useful to the characterization of architectures and urban sites. To this line
of research, studies on traditional architectural lexicons are related too, in order to recover and validate them on the
occasion of the restoration; they are carried out for the University and Scientific Research Education Ministry - CNR, as
part of the Active Projects of State Administration (Research line n. 1 "Le tecniche di intervento tradizionale: recupero,
aggiornamento, validazione” – Traditional techniques of intervention: recovery, updating, validation) and for some
municipalities that wished provide themselves with Recovering Manuals or Codes of Practice. Last experience, in
chronological order, is constituted by the realization and circulation of the recent Architecture Thesaurus,
commissioned by MiBAC-ICCD at "Roma Tre" University to develop linguistic standards necessary to protect and
catalogue the Cultural Architectural Heritage. On the base of these premises the activity, currently, is directed to the
foundation and experimental check of a system with integrated activities of research and training for the
documentation, preservation and management of specific environmental contexts, both natural and anthropological,
both living (historical centres) and archaeological. The conservation, with seismic safety, of buildings and sites and
their enhancement for the purposes of tourist use, is designed by identifying and characterizing the possible material
and immaterial attractions, distinctive for the several places considered. The system is based on the development of the
analyzing methodologies and management procedures of the information produced during cognitive and planning
actions, carried out by architects and archaeologists together, within an educational context intent to fully document the
sites and schedule the enhancement. The results of the teaching activity, mainly on the field, and applied research
consist in formation of digital platforms, with its appropriate compiling glossary, through which to relate a range of
selected and standardized information, necessary to a conscious planning of the conservative measures and an efficient
management, in time, of the technical interventions for maintenance, restoration and enhancement
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
