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
Unlocking the informal economy: a literature review on linkages between formal and informal economies in developing countries
No full textGrowing awareness of the size and organizational potential of informal economies in the era of globalization has triggered a profusion of research on linkages between the formal and informal economies, moving in a range of empirical and theoretical directions. This Working Paper reviews over 200 items of current literature on formal-informal linkages under four categories linkage mapping, institutional design, governance effects, and the politics of formal-informal linkages. The paper focuses not only on patterns of linkages and whether they are beneficial or not, but also for whom, and with what impact on the governance structures of formal as well as informal economies. After examining what the existing literature reveals and identifying research gaps, the author outlines policy implications and a framework for further research
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Identity economics: social networks and the informal economy in Nigeria
No full textWhy have informal enterprise networks failed to promote economic development in Africa? Although social networks were thought to offer a solution to state incapacity and market failure, the proliferation of socially embedded enterprise networks across Africa has generated disorder and economic decline rather than development. This book challenges the prevailing assumption that the problem of African development lies in bad cultural institutions by showing that informal economic governance in Nigeria is shaped, not just by culture, but by the disruptive effects of rapid liberalization, state decline and political capture. Identity Economics traces the rise of two dynamic informal enterprise clusters in Nigeria, and explores their slide into trajectories of Pentecostalism, poverty and violent vigilantism. Drawing on over twenty years of empirical research on African informal economies, the author highlights the institutional legacies, networking strategies and globalizing dynamics that shape the regulatory role of social networks in Africa's largest and most turbulent economy. Through an ethnography of informal economic governance, this book shows how ties of ethnicity, class, gender and religion are used to restructure enterprise networks in response to contemporary economic challenges. Moving beyond primordialist interpretations of African culture, attention is drawn to the critical role of the state and the macro-economic policy environment in shaping trajectories of informal economic governance
