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
Interpreting Patterns of Interaction between Civic Activism and Government Agency in Civic Crowdfunding Campaigns
Full text linkAddressing the under-researched interplay between civic activism and government agencies, this paper focuses on the conditions for broad local support for civic crowdfunding projects and the interaction between proponents of such projects, their associated stakeholders, and traditional urban planning frameworks. Building on Carolina Pacchi's work on the relationships between community and state in examples of local activism in European cities, the paper applies four types of relationship between community and state: state regulation and community implementation; cooperation; community autonomy; and community opposition. These are used to unpack the different phases of civic crowdfunding projects and to show how relationships with the state evolve throughout the lifecycle of a project. Drawing upon qualitative research carried out in London and Milan between 2015 and 2017, we examine the case of the Peckham Coal Line in south London, a proposed urban elevated park along a disused coal line. Chosen for its long-term ambitions, its substantial local support and financial backing through mayoral match-funding, the case is used to examine the dynamic interaction between the digitally enabled activism of civic crowdfunding and local government agencies. Our study of the development of the Peckham Coal Line project gives insight into the shifting nature of the relationship between civic actors and the state, showing that while the 'autonomous' development of local projects is an important aspect of civic crowdfunding projects, the state does not disappear. Further, online and offline activities are only one step in the redefinition of contemporary forms of citizenship and the claim that civic crowdfunding can deliver extended citizen participation should be more closely scrutinized crowdfunding projects, the state does not disappear.

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
Civic Crowdfunding and the Negotiation of New Urban Public Spaces
No full textThis paper draws on qualitative research, carried out in London and Milan, to investigate the growing phenomena of civic crowdfunding projects.
This approach is framed by interdisciplinary debates around governance and collaborative, community-led initiatives aiming at making cities more inclusive and sustainable. In particular, this work draws on discourses around actor- network theory, diverse economies and spatial agency, to focus on the negotiation of new and alternative networks of urban governance (both off-line and on-line), and on to what extent these can be seen as socially innovative. In this context the paper discusses how technologies can be employed to empower citizens in envisioning, designing and shaping the future of the city through local, bottom up and innovative initiatives like civic crowdfunding, but also what is the role of Local Government in fostering the emergence of and supporting such initiatives. By exploring innovative practices emerging in a highly formal planning system, this paper discusses the potential role of self-organised groups in producing alternative views of the city, against or within dominant urban development practices
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
