Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Rupture technologique et dynamique d’une industrie : la transition vers l’électromobilité
No full textStrict regulations force global players to invest heavily in the production of electric vehicles. Electrification is a systemic innovation whose massification should disrupt the vehicle dominant design. “Could this disruption durably destabilize the industrial architecture of a sector, considered as very resilient?”An empirical study on the electric traction value chain, confirms, to date, the resilience of this industry as carmakers remain the focal actor: electrification alone is not enough to destabilize this industry!But, technological innovations, new societal challenges, new powerful players in the mobility market influence the future of this industry.“Could this combination of factors internal and external to the industry facilitate a disruptive dynamic?”By analyzing 10 case studies of innovative mobility services worldwide, this thesis identifies 3 ideal types: “mobility service added to product”, “robotaxi”, “territorialized open mobility platform”. If the first one is a natural extension of The carmakers' business, the last two have the potential to destabilize the automotive industry.An empirical comparison, between China and Europe, of the governance of environmental regulations, states that China is now in capacity to impose its standards worldwide through a planning capacity combining directiveness, intrusiveness and agility.Theoretically, it confirms strategic theories and the interest of building upon the STT paradigm to shed light on transitions in this industry. It contributes to innovation management and servitization fields by proposing a design space for the development of mobility services and confirms that project is an important learning vector in a nascent ecosystem. This thesis supports the hypothesis of an avalanche of converging causalities leading to the destabilization of the historical architecture of the automotive industry. In accordance with the theory of transitions, the modes of regulation between these different factors will shape these potential destabilizations.Des réglementations strictes obligent les constructeurs à investir massivement dans la production de véhicules électriques.

Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
