    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” 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

    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

    Le CUBE : une architecture de modèle de système centrée sur l'utilisateur pour la migration de services Web via plusieurs périphériques

    Dans la tendance d'Internet, nous commençons à compter nos activités quotidiennes sur les systèmes de base en nuage pour stocker nos données et pour suivre tout notre état et comportement lors de l'utilisation de services Web. Par conséquent, nos données ne sont plus sécurisées comme auparavant, car nous avons délégué la responsabilité de les protéger, de les sécuriser et de les stocker à des tiers. Ces dernières années, de grandes entreprises telles que Yahoo, Facebook ou LinkedIn ont été victimes de plusieurs fuites, ce qui montre à quel point nous sommes vulnérables. Nous disposons aujourd'hui d'appareils mobiles plus puissants que jamais. Cependant, nous n'explorons pas leurs capacités en matière de traitement, de stockage et de mesures de sécurité pour utiliser les services Web localement. De plus, nos appareils sont fondamentalement divisés en deux mondes différents, ceux avec Android et ceux avec un système d'exploitation iOS. Néanmoins, avec la popularité de la technologie mobile, notre comportement a changé. Aujourd'hui, il est courant de trouver un utilisateur utilisant deux ou trois appareils mobiles en même temps, souvent avec un système d'exploitation différent. Par conséquent, nous sommes simultanément confrontés à un environnement à plusieurs périphériques avec le même système d'exploitation ou des systèmes d'exploitation différents, dans lequel la plupart des technologies et des services Web nécessitent le recours à un fournisseur tiers pour la synchronisation et le maintien de l'état de nos tâches quotidiennes. Bien que ce scénario chaotique concerne plusieurs appareils et systèmes d'exploitation, il existe une technologie mentionnée précédemment à la fin des années 90, appelée Liquid Software, qui pourrait être une solution pour harmoniser ce scénario. Le Liquid Software vise à permettre une migration fluide vers différents appareils avec ou sans le même système d'exploitation, tout en préservant l'expérience utilisateur d'une application ou d'un service donné. Dans cette thèse, basée sur les principes de Liquid Software, nous nous concentrons sur un environnement multi-périphériques capable de synchroniser le service Web côté client sans dépendre d'un système de base Cloud. Nous avons proposé une architecture basée sur des modèles, appelée Le CUBE, qui utilise des principes centrés sur l'utilisateur combinés à différentes technologies, telles que les principes REST et RESTful. Le CUBE propose également un modèle à quatre couches dans lequel REST et RESTful fonctionnent indépendamment l'un de l'autre mais en coopération. Un autre élément critique du CUBE est la couche de conversation (CC), modélisée dans le but de permettre la modification des données / états à partir des services Web. La CC utilise des techniques de traitement du langage naturel pour trouver et définir des services Web adaptés à l'utilisateur. Une autre contribution du CUBE est la création d'une sorte de réseau d'utilisateurs appelé INNER CUBE, avec tous les appareils mobiles appartenant à un seul utilisateur. Le but de la combinaison de ces éléments au sein d'une seule unité, le CUBE, est de permettre le transfert fluide de services/données et de sessions d'appareils (ordinateurs de bureau, ordinateurs portables et téléphones mobiles) vers d'autres appareils, quel que soit leur système d'exploitation, et au même temps, entièrement transparent pour l'utilisateur final, tout en réduisant la dépendance du fournisseur tiers. Nous avons également proposé deux tests pour valider le modèle CUBE.Within the trend of the Internet, we start to rely our daily activities on Cloud Base Systems to store our data and keep tracking all our state and behavior while using Web Services. Therefore, our data are no longer safe as before since we have delegated the responsibility to keep them safe, secure, and stored by third-party providers. In the last few years, big companies such as Yahoo, Facebook, or LinkedIn were victims of several leaks, which demonstrates how vulnerable we are. We have nowadays more powerful mobile devices than ever before. However, we do not explore their capacities regarding processing, storage, and security measures to using Web Services locally. Moreover, our devices are basically divided into two different worlds, those with Android, and those with an iOS operating system. Nevertheless, with the popularity of mobile technology, our behavior has changed. Today it is common to find a user using two or three mobile devices at the same time, and often they have a different operating system. Therefore, we are facing simultaneously a multiple-device environment with the same or different operating systems, where most of the technology and Web Services requiring a third-party provider to synchronizing and keep the state of our daily tasks. Although of this chaotic scenario regarding multiples devices and operating systems, there is a technology earlier mentioned at the end of 90's called Liquid Software that may be a solution to bring harmony to this scenario. The Liquid Software aims to allow for fluently migrate towards different devices with or without the same operating system, and at the same time keep the user-experience of a given application or service. In this thesis, based on Liquid Software principles, we focus on multiple devices environment able to synchronize Web Service at the client-side without depending on a Cloud Base System. We proposed the model-based architecture, called the CUBE, that makes use of User-Centric principles combined with different technologies, such as REST and RESTful principles. The CUBE also proposes a four layers model where REST and RESTful work independently from each other but in cooperation. Another critical element of the CUBE is the Conversation Layer (CL), modeled with the purpose to allow change data/state from Web Services. The CL makes use of techniques of Natural Language Processing to find and defining suitable Web Services to the user. Another contribution of the CUBE is creating a kind of user-network called INNER CUBE with all mobile devices that belong to a single user. The aim of combining these elements inside a single unit, the CUBE, is to allow for fluently move services/data and sessions from devices (desktops, laptops, and mobiles phones) to other ones regardless of their operating system, and at the same time, entirely transparent for the final user, and also reducing the dependency of the third-party provider. We have also proposed two tests to validate the CUBE model

    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

    A configuration-based approach as end-user development for personalized travel mashup

    Le développement du Web 2.0 et l’émergence du Cloud Computing ont engendré une augmentation importante et continuelle des volumes de données collectées, stockées et partagées. Ces dernières, souvent stockées dans des sources de données diverses et appartenant à des organismes et/ou domaines différents, nécessitent pour être exploitées des efforts d’intégrations souvent important, notamment quand les sources sont distribuées et hétérogènes. Nous nous sommes intéressés à une telle problématique, dans le contexte de services de données, en proposant, dans un environnement ouvert et dynamique, une solution d’intégration de données construite à la volée par les utilisateurs afin de résoudre des demandes d’information liées à leurs vies quotidiennes. Nous avions plus particulièrement la construction de plans touristiques en Centre-Val-de-Loire comme domaine d’application. Nous avons proposé une approche basée sur la théorie de la configuration et des techniques de mashup pour interconnecter un ensemble de services et APIs Web en vue de répondre à une requête de plan touristique. Notre solution est destinée à des utilisateurs novices en offrant un environnement de création de services intuitif.Les paradigmes visuels cachent en effet la complexité typique de la composition des services, de l'intégration des données ainsi que les applications sensibles au contexte pour aider les utilisateurs finaux à créer des applications de mashup personnalisées. Un type spécial d'application Web, appelé Linked Data Mashup, utilise l'initiative Linked Data pour créer une vue intégrée des différentes sources de données liées et exploiter les données sémantiques. Puisqu'il existe des relations logiques sous-jacentes entre les données, une navigation dans le graphe de données explorant ces relations logiques aiderait à stimuler la personnalisation du mashup.The fast development of powerful rich Internet applications and the growing availability of information on the Web is stimulating researchers to investigate data overload phenomenon. The potential of mashup techniques to address seamless integration of data and services to provide a unified view of the information is presented as an evident solution. However, the opportunity to access a large amount of information does not always in harmonization with the people knowledge. In fact, the data deluge we are confronting today virtually leds people to continuously discover new information that they do not know how to manage and filter to obtain the most suitable to their current need. The recent development of mashup tools has refueled research on end-user approach allowing users without programming skills to create, consume, and manage added value services throught designing their own application.This thesis presents a novel mashup approach for end-user development. That is, we introduce a domain-specific approach to mashups that is aware of the concepts and conventions of the domain and where the user is comfortable with. The domain-specific approach mashup approach is based on configuration theory that, in generic point of view, allows users aggregate components by selecting appropriate ones whose respect user constraints. We illustrate the configuration based-mashup approach by implementing a mashup plateform regarding the tourism domain to help visitors in customising their trip planning in Loire Valley region.In line with visual programming paradigm, our approach is characterized by the adoption of design environments that take advantages of the use of high-level visual abstractions. Visual paradigms indeed hide the complexity typical of data integration and also the context-awareness apps to assist end-users in the creation of personalized mashup applications. A special kind of web application, called Linked Data Mashup uses the Linked Data initiative to build an integrated view of different Linked Data sources and take advantage of semantic data. Since there are underlying logical relations between the data, a deep convergence of all the data and full considerations of such logical relations would help to boost mashup personalisation
