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
Sociale huisvesting en levensonderhoud, een vergelijkende studie in Groot Caïro.
No full textThe housing of low-income groups in Greater Cairo has always been difficult. The general shortage in housing supply is contrasting with the low occupancy rate of newly constructed public housing units. In contrast, despite their bad living conditions, informal settlements have a high occupancy rate. In order to analyze the reasons behind this contradiction, the study compares four neighbourhoods ranging from the formal Mubarak Youth Housing Project in Zaied, the semi-informal public housing of Ain El-Sira to the informal settlement of Manshiet Nasser and including the rehabilitation project of new Zeinhum.For a further understanding of the meaning of the house and habitat, a political economy approach is adapted. The house as a place of everyday life and a method to access livelihood resources is illustrated. In a first attempt, the study related housing policies to the political context of the Egyptian government. Then, an analytical framework is developed to get an insight in the integration mechanisms from the point of view of citizens and inhabitants. The analytical framework integrates the livelihood capitals (Human Capital, Physical Capital, Social Capital and Political Capital) and the modes of economic integration from Karl Polanyi (redistribution, market exchange and reciprocity). While, the livelihood framework test accessibility to livelihood resources through market relationship from individuals level, the three modes of economic integration are used to add the space and social reproductions dimensions through reciprocity and redistribution relationships. One hundred twenty seven interviewees were interviewed in order to analyze the livelihood resources in the four housing case studies. The results of the interviews were grouped and analyzed using the principle correspondence analysis. A final comparison shows the livelihood resources in terms of the three spheres of economic integration. The findings indicate a preference among low-income groups for informal settlements because of three main reasons: the advantages of geographical location, the nature of social networks and the strength of private redistribution systems, thus enabling an easier access to means of existence. The results and recommendations are further discussed.status: Publishe
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
