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
Strengths and Challenges of Community Participation in an Urban Transport System – a Case Study of the Hong Kong MTRC
No full textAbstract: In response to the conference sub-theme “community participation”, this paper proposes to examine the social impact of the community participation efforts undertaken by the Hong Kong Mass Transit Railway Corporation (MTRC) during the planning and construction of the new West Island Line (WIL). Hong Kong has long been known for a ‘top-down’ governmental structure that has dominated most urban planning processes in the past few decades. In the case of transport or infrastructural projects, the ultimate objective has been to maximize economic and social efficiency. Lately, however, we have witnessed a paradigm shift towards more active public engagement and better communication between stakeholders. In this changing context, this research aims to study and evaluate the significant social and community attributes associated with MTRC’s ‘bottom up’ participatory approach in the planning of the West Island Line. The new WIL, which began construction in 2005 and will be completed in 2014, is a westbound extension of the existing Island Line that will connect old districts like Sai Ying Pun, Shek Tong Tsui and Kennedy Town with Hong Kong’s Central Business District. The WIL project is of particular interest because MTRC has implemented extensive public participation opportunities into its planning process from the very beginning. Though the project is yet to be completed, social and community impacts are already emerging. The research objectives of this paper are threefold: 1) to identify the strengths and challenges of community participation in an urban transport system in Hong Kong; 2) to evaluate how community participation can better integrate infrastructural systems within the urban fabric in order to achieve economic, social and cultural sustainability; and 3) to propose to policy makers and urban planners how a comprehensive public participatory methodology can help improve current infrastructural planning practices in the context of contemporary urbanism. The research aims to produce a set of policy recommendations based on the Hong Kong model that can be adaptable to other urban contexts
