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
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
Evolving Urban Culture in Transforming Cities Architectural and Urban Design in a Fluid Context
No full textThe practice of architectural and urban design being involved in forming the space in our cities and built environments has certain effects on the social life in society that in its turn conditions the performance of the practice. The continuous changes in cities and societies, however, are just partially caused by the practice of architectural and urban design. In a fluid context of social and spatial transformations, the control and manipulation of the effects of the practice become yet more complicated entailing a deeper understanding of the nature of urban transformations and the dialectic between urban life and its spatial frames in cities. The objective of this thesis is to improve this understanding. The thesis deals with discourses in the fields of theory of architecture, architectural and urban design practice and sociology. It examines the concepts of society, space and culture and discuses the content and historical context of predominant urban design ideas and concepts in different periods. The thesis comprehends historical studies, empirical fieldwork and case studies. Historical data is dealt with very concisely. The case studies, however, include a wide range of settlements, places and houses. These studies attempt to understand the mechanism of the formation and transformation of different urban systems. The theoretical basis for argumentation, and the methodological tools applied in the analyses of the case studies are the analytic theory and methodology of Space Syntax. Space Syntax is a theory of the built environment that reveals its hidden properties where it is most involved in our social life. The theory, through modelling and analysing the abstract spatial structure of the built environment, helps to convert the tacit and intuitive knowledge of space; the main subject of architectural and urban design, into explicit analytic, hence, testable knowledge. The application of Space Syntax in the studies of this thesis has helped to bring to light the potentials of spatial systems in cities generated in different processes of urban transformation. The findings of this thesis; the results of spatial analyses of cities and their concordance with functional, sociological and historical data, support the theory of Space Syntax, and display the capacity of the theory for development and its extension of applications
