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
Le potentiel transformateur de la responsabilité sociale des entreprises dans la chaîne mondiale du cacao et du chocolat : aperçu des pratiques de certification de la durabilité au Ghana
No full textCette étude examine les implications de la responsabilité sociale des entreprises (RSE) des entreprises transnationales (ETN) appliquée à leurs chaînes de valeur. Prenant le cas d'un projet de certification de la durabilité du cacao UTZ au Ghana, l'étude analyse le processus de mise en œuvre d’un projet de la RSE et ses résultats localement. La chaîne mondiale du cacao et du chocolat (GCCC) est un cas particulièrement intéressant pour cette étude car elle est confrontée à des défis complexes en matière de durabilité, notamment l'extrême pauvreté des planteurs de cacao et la dégradation de l'environnement dans les zones de production. Par conséquent, des multiples projets de RSE se sont généralisés au cours des dernières décennies. L'étude interroge comment les stratégies de RSE affectent les conditions de durabilité et qui en bénéficie finalement. Ainsi, elle met l'accent sur les changements dans l'organisation du secteur cacao au niveau local au Ghana et sur les perspectives futures des planteurs de cacao. L'étude révèle que la RSE aide plutôt les ETN à accroître leur influence sur la production locale de cacao au lieu de surmonter les principaux défis de durabilité dans la GCCC.This study engages with the implications of a Corporate Social Responsibility (CSR) of Transnational Corporations (TNCs) in their supply chains. Taking the case of an UTZ cocoa sustainability certification project in Ghana, the study examines the implementation process of a transnational CSR intervention and its local outcomes. The Global Cocoa-Chocolate Chain (GCCC) is a particular interesting case for this study because the GCCC is facing complex sustainability challenges, most notably the extreme poverty of millions of cocoa farmers and environmental degradation in production areas, and therefore, CSR projects became widespread over the past decades. The study explores how CSR strategies affect sustainability conditions in a supply chain and who is finally benefitting from it. Thereby, it puts a particular emphasis on changes in the organization of the local level Ghana’s cocoa sector linked to CSR and in farmers perspectives. The study reveals that CSR rather helps TNCs to increase their influence over local cocoa production instead of overcoming key sustainability challenges in the GCCC
Certification privée pour la production de cacao durable et ses transformations locales: Aperçus depuis le Ghana
No full textInternational audienceBased on a UTZ certification project in Ghana, this article analyzes the transformations occurring in the functioning of the cacao sector at the local level. The certification system put in place using a private-private partnership is effective in terms of technical support and agricultural training and seems to have a positive impact on productivity. But the life circumstances of producers and their position in the sector are not improved in a sustainable way; rather, we find reinforced asymmetries.À partir d’un projet de certification d’UTZ au Ghana, l’article analyse les transformations du fonctionnement de la filière du cacao au niveau local. Le système de certification mis en place en partenariat privé-privé est efficace en termes d’accompagnement technique et de formation agricole et semble avoir un impact positif sur la productivité. Mais les conditions de vie des producteurs et leur position dans la filière ne sont pas améliorées de manière durable, on trouve plutôt des asymétries renforcées
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
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
