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
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

No full textMafeje: scholar-activist with noble convictions
No full textThis critical review of an edited volume of Archie Mafeje's writings closes gaps in what is known about his political upbringing, his scientific methodology and posthumous intellectual influence. Trained in the radical political tradition of the Unity Movement of South Africa, Mafeje was a celebrated social theorist, broke with liberal functionalism in social anthropology and wrote prolifically. This important volume is silent on standout questions, such as: why did Mafeje, the mature scholar-activist, dissociate himself from practical politics after relocating from Cairo to Pretoria, given the crisis of the radical left in South Africa? To what extent did Mafeje wield his mastery of dialectical logic not only to interpret the world but actively change it? What was Mafeje's orientation toward agrarian transitions beyond capitalism in countries like South Africa? In response to these thematic questions, this essay synthesises insights from relevant chapters.
Equitable rural socioeconomic change: land, climate dynamics, and technological innovation
No full textMore and more of global economic wealth and decision-making power rests with fewer and fewer people, while acute socio-economic inequities continue to afflict large rural communities in Africa, Latin America and Asia. Land inequalities remain a burning question for rural communities.
Equitable Rural Socioeconomic Change brings together original reflections on the intricacies of economic and social transformations that are unfolding in the rural areas of developing countries, and provides a fresh and authentic perspective. This compelling book revisits dominant but exhausted conceptions of rural livelihoods to expose their analytical flaws and thematic limitations. In this book, the interacting themes of land, climate dynamics and technological innovation are brought into a coherent whole through a re-examination of the lens of unequal ownership, control and use of a society's productive means.
Equitable Rural Socioeconomic Change is the first multidimensional and integrated analysis of rural socio-economic change anchored around rising structural polarisation in the 21st century.
