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
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

Semantic approach to design connected services : architecture, composition algorithm, smart home application
No full textDans le contexte de l’Internet des Objets, la conception de services connectés – c’est-à-dire de services portés par des objets connectés – nécessite une approche de bout en bout pour non seulement répondre aux attentes des bénéficiaires de ces services mais aussi pour adapter le fonctionnement de ces services à des conditions d’exécution très variées allant de la maison à la ville connectée. L’approche sémantique proposée par cette thèse offre un niveau d’abstraction qui permet aux concepteurs de services de se concentrer sur les aspects fonctionnels des services et des objets. Elle s’inscrit dans un cadre d’architecture plus large qui aborde, en plus de ce niveau sémantique, les aspects plus opérationnels de mise en oeuvre de ces services (niveau Artefacts) dans des environnements techniques éventuellement hétérogènes (niveau Ressources). En proposant cette approche sémantique de conception, la thèse vise plusieurs objectifs qui peuvent être regroupés en trois catégories. La première catégorie d’objectifs est de décloisonner le monde actuel des services connectés en découplant les services des objets connectés et en permettant le partage d’objets par plusieurs services connectés. L’ouverture induite par ces premiers objectifs conduit à viser une deuxième catégorie d’objectifs qui a trait à la composition des services connectés. Chaque service devra être conscient et adopter un comportement compatible avec les autres éléments de son contexte d’exécution. Ces éléments de contexte comprennent bien sûr les autres services mais aussi les phénomènes physiques et les actions des occupants des espaces concernés. Enfin, la troisième catégorie d’objectifs s’adresse plus s’adresse plus particulièrement aux bénéficiaires des services connectés afin d’optimiser l’expérience utilisateur par des attentes mieux prises en compte et des automatismes respectueux des comportements humains. Le fondement théorique de l’approche sémantique proposée dans cette thèse s’appuie sur un méta-modèle qui permet de définir les éléments de modélisation nécessaires pour modéliser les services, les objets connectés et les comportements des services sous forme déclarative.In the context of the Internet of Things, the design of connected services - that is, services supported by connected objects - requires an end-to-end approach to not only meet the expectations of the recipients of these services but also to adapt the operation of these services to a wide range of execution conditions spreading from smart homes to smart cities. The semantic approach proposed in this thesis provides a level of abstraction that allows service designers to focus on the functional aspects of services and objects. It is part of a larger architecture framework that addresses, in addition to this semantic level, the more operational aspects of implementation of these services (Artifacts level) in potentially heterogeneous technical environments (Resources level). By proposing this semantic design approach, the thesis aims at achieving several objectives that can be grouped into three categories. The first category of objectives is to decompartmentalize the current world of connected services by decoupling services from connected objects and allowing the sharing of objects by several connected services. The openness induced by these first objectives leads to a second category of objectives that relates to the composition of connected services. Each service will have to be aware and adopt a behavior compatible with the other elements of its execution context. These contextual elements include of course the other services but also the physical phenomena and the actions of the occupants of the spaces concerned. Finally, the third category of objectives focusses on at the recipients of connected services in order to optimize the user experience through better requirement management and automatisms respectful of human behaviors. The theoretical basis of the semantic approach proposed in this thesis is a meta-model that defines the modeling elements needed to model services, connected objects and service behaviors in a declarative form
