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
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
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
Strike action and self-help associations: Protest and culture of African workers after World War I, Zimbabwe
No full textAfrican Studies Seminar series. Paper presented 26 October 1987The years immediately following the armistice of the First World War
witnessed the rapid growth of labour movements throughout the world.
In sub-Saharan Africa, despite the region's relative weakness of
capitalist penetration, the period was punctuated by stirrings of
industrial discontent among African workers, apart from a contemporary
spate of strikes by European workers in settler-dominated
southern Africa. The places affected ranged from Freetown to Cape
Town, from Lagos to Lourenco Marques, from Nairobi to Johannesburg
and many other industrial centres. Southern Rhodesia, now Zimbabwe,
was no exception. In the period from 1918 to 1921 African workers
are known to have mounted several work stoppages in major towns,
railways, mines, etc. throughout the colony. None of these disputes
was more than a 'skirmish', lasting only a short while, but together
they constituted a militant strike movement or movements. The first
part of this essay is an attempt to describe this upsurge of labour
protest. The protest on such a scale was perhaps the earliest of
its kind in the colony's history and much of it has so far remained
in obscurity; as such, it deserves to be accounted in detail. The image of the African worker that can be obtained from the
first part is, insofar as its concern is restricted to the protest
scenes, inescapably a very much simplified and abridged one: he is
to be depicted as a man rationally and milltantly responding to
economic realities of an industrial society. In order to probe more
deeply into the character of the African worker, the labour protest
of 1918-21 needs to be placed on a wider historical canvass. For
this purpose, the second part of this essay addresses itself to a
case study of the Tonga or Zambesi municipal workers in Salisbury
(Harare) who staged a strike in August 1919. Its emphasis is upon
penetrating the interior of the world which African migrants created
in the face of everyday problems—a world, made of intimate human
ties, where people found natural and effective forms of self-protection
and self-assertion in the industrial situation
African Harare, 1890-1925: Labor Migrancy and an Emerging Urbaqn Community (1)
Full text linkWhilst there have been relatively intensive studies, both sociological and historical, into the African "urban question" for mid-century Zimbabwe, its earlier phases, shortly after the encounter of African societies with colonial capitalism, remain largely a virgin territory as a field of research. This study is an attempt to redress the imbalance by investigating the structure and development of the African community in early Salisbury. It focuses especially on (1) the conjuncture of the advent of mass labor migrancy by the early 1920s and the heightened collective consciousness of migrants in the form of labor protests and mutual aid associations, and (2) the contrast of two emerging African neighborhoods--the inner Salisbury, largely alien and marginalized, and the outer Salisbury, largely indigenous and "respectable
