The agrarian question in Southern Africa and "Accumulation from below" : economics and politics in the struggle for democracy
No full textDemocratisation is on the agenda in Africa, but as the author stresses, this is not just a political question. Alternative forms of accumulation from below must be addressed, and this he does against the backdrop of the historical experiences of Southern Africa

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
A critical analysis of theories of agricultural development and agrarian reform, with reference to agrarian reform policies in Chile (1962-1973).
No full textThis thesis is a work of theory; it is also historical. It
attempts to provide a critique of the categories through which
the phenomena of agricultural development and land reform are
habitually grasped. It is divided into three parts.
In the first part three main theoretical orientations to the
study of capitalist agrarian development are discussed, both
abstractly and with reference to their accounts of Latin
American rural society in the 1960's. It is argued that all
three are unable to explain adequately the process of social
and agrarian change. This inability is traced to the fact
that all three reduce social totalities to two or more distinct
sub-entities or sub-totalities. The author calls this general
position the social problematic of dualism. Its inability. to
account for social change is, he argues, traceable to the fact
that the existence of the sub-entities into which social
totalities are divided, is posited as theoretically prior to
the relations which connect them. These points are pursued
in the second and third parts of the thesis.
In the second part an alternative to dualism' with pärticular
reference to its variants of the separation of a realm of'
industry from a realm of*agriculture, and of the separation
of a realm of the economic from a realm of the social, is
provided through a detailed theorisation of capitalist social
relations. It is argued that the existence of distinct realms
of agriculture, industry, economy and society is a real effect
of the essential relations of capitalist society, and that
these divisions must be transcended through an elucidation of
the character of such relations. This is done by distinguishingi;
three forms of capitalist development which are produced by
these essential relations. Further examples of a dualist
analysis in contemporary theorisations of petty commodity
production, the world economy and the articulation of modes
of production are discussed.
In the third part the author returns to an examination of the
Latin American context through a discussion of the case of
Chile. The theoretical insights developed in the earlier
parts are systematically applied to various aspects of Chilean
history from the conquest of Latin America to the 1960's, and
to the processes of land reform which covered the decade
1962-1973. It is suggested that the agrarian social transformations
which this country experienced are only explicable in
terms of a position which systematically transcends all dualist
assumptions.University of Bradfor
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
