Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Intermodality between artisanal transport and public transport by bus in Grand Lome
Intermodal practices are related to the use of several distinct modes of transport during the same displacement. This study analyses the articulation between institutional transport insured by motorbike taxis and the Lomé Transport Company (Sotral) in Grand Lomé. In particular, it explores two intermodal practices between both actors, mainly the drawdown and broadcasting of Sotral users on/and from bus stopping, the main intermodality points after the bus stations in Grand Lomé. The methodology relies on a mixed approach, combining quantitative and qualitative methods for data collection and analysis. The first descriptive approach has allowed us to observe the phenomenon, to reinforce knowledge through the analysis of documents, and to obtain actors’ opinions. The second quantitative approach is based on the interviews carried out with drivers and motorbike taxi and bus users, the counting of broadcasting and drawdown modes at the stopping points, and the mapping of the study area as well as the Sotral network. The results show that the current facilities of Sotral bus stopping points do not encourage/promote the interaction and/or cohabitation between different modes of transport, such as motorbike taxis. These infrastructures are out of phase with the intermodal practices of the population of Grand Lomé, who use artisanal and structured public transport in their daily movements. In fact, motorbike taxis do not have a dedicated facility for drop-off/pick-up of passengers at the Sotral bus stopping points. The drawdown and broadcasting by these means of artisanal transport at bus stops are generally made on sidewalks and sometimes on roadways, which is a source of road insecurity. This failure leads to friction between Sotral and motorbike taxis on the use of facilities dedicated to Sotral buses, creating an absence of cohabitation between two main actors of mobility in Grand Lomé. An approach focused on the flexibility and efficiency of intermodal points or the connection between motorbike taxis and Sotral allows good coexistence and constitutes a component of a sustainable mobility strategy
La diffusion des services de e-hailing dans les villes d’Afrique
International audienceDepuis l’introduction d’Uber en Afrique du Sud en 2013, les services de e-hailing se sont diffusés au sein des systèmes de mobilité de nombreuses villes en Afrique. Cette évolution donne lieu à une littérature croissante, mais qui s’est encore peu intéressée aux populations jeunes. Ces dernières rencontrent pourtant des difficultés de mobilité importantes, liées à des ressources limitées et des services de transport largement défaillants. Cet article s’intéresse aux jeunes usagers du service de e-hailing Gozem à Lomé (Togo), en étudiant leur profil, leurs logiques d’adoption de ce service, les effets sur leurs pratiques de mobilité et, plus largement, sur leur accès à la ville. Il se base sur une enquête par questionnaire auprès de 266 personnes âgées de 15 à 34 ans, complétée par 10 entretiens approfondis. Les résultats montrent que les jeunes usagers du e-hailing dans le grand Lomé sont généralement instruits et disposent de ressources financières et d’un accès à un mode de transport motorisé (souvent une moto et rarement une voiture) souvent supérieurs à la moyenne des habitants. Le service de e-hailing est adopté essentiellement pour son aspect pratique et ses qualités en termes de sécurité, de confort mais aussi de prestige social. Il apporte aussi des améliorations en termes de mobilité et facilite globalement l’accès des jeunes Loméens aux aménités urbaines « ordinaires » (travail, études, lieux de loisirs et de consommation), notamment aux heures de pointe et la nuit. Toutefois, en raison de son coût, son usage demeure peu fréquent, et sert des déplacements, individuels ou à plusieurs, qui n’auraient pas pu être réalisés autrement ou qui auraient été effectués en taxi-moto, taxi collectif ou moto personnelle. Dans ces conditions, le e-hailing apparaît comme un vecteur de consolidation de la place de la voiture dans les pratiques de mobilité et les imaginaires des jeunes Loméens
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
