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

We give the detailed specification of the system by introducing a special notation based on pattern-matching, which permits to unify the descriptions of assignments, tests and LISP data structures. Our notation permits the specification to be machine independent and avoids thennotion of abstract syntax.Nous décrivons la structure d'un système LISP : VLISP, conçu spécifiquement pour être implémenté sur mini-ordinateurs. Nous en définissons en détail le noyau : interprète et extensions, en utilisant le mode de description par filtrage, ce qui nous permet de ne pas faire dépendre la description d'un mini-ordinateur particulier, tout en permettant d'éviter l'introduction d'une syntaxe abstraite.Nous introduisons une fonction de contrôle inédite en LISP, dont la puissance nous permet de réaliser avec succès un compromis entre la nécessité d'obtenir un système LISP utilisable, et les restrictions, en particulier en taille mémoire disponible, liées à l'emploi des mini-ordinateurs
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

An evolutionary supported multi agent system methodology for computer aided cellular architectural design
No full textNous proposons un cadre méthodologique de conception architecturale qui utilise opérations et outils de l'intelligence artificielle: nous proposons, dans cette étude, de matérialiser un espace architectural a priori imaginaire et global par des opérations d'instanciations et de réifications essentiellement locales de conception cellulaire. L'Espace Architecte (EA) est un espace imaginaire. L'édifice auquel cet espace peut correspondre, étant bien réel, est une transcription matérielle des propriétés de cet EA, et aussi la résultante de contraintes, de choix, de pressions physiques et sociales. Cette résultante est l'aboutissement et l'effet d'opérations rassemblées en structure. Les opérations, qui sont dotées de propriétés formelles et algorithmiques, constituent les outils de matérialisation d'un EA. Les structures opératives, vu la complexité des EA imaginaires à réaliser mettent en jeu pour l'instant une informatique de modélisation et d'optimisation qui relève clairement de l'intelligence artificielle d'aujourd'hui: heuristiques, monte-carlos, sélections et évolutions artificielles, multi-agences. Nous proposons un répertoire et une mise en ordre de ces méthodes et leur applications à la conception en architecture. Nous examinons à cette occasion les aspects de l'histoire de l'architecture qui mènent logiquement vers notre approche. Dans l'introduction, nous présentons la problématique (les origines, le but, les limites et les usages) de la méthode proposée. Dans le premier chapitre, nous présentons un système de multi-agences, supporté par une méthode évolutionniste. Dans le second chapitre, nous décrivons une interface architecturale, qui s'interpose entre le système de multi-agences et l'Architecte utilisateur. Dans le troisième chapitre, nous décrivons les principes de l'histoire et de la théorie de l'architecture. Dans le quatrième chapitre, nous répondons à la question "pourquoi l'Architecte a besoin de concepts et méthodes de l'intelligence artificielle?", en parcourant brièvement les théories, méthodes et applications associées. Finalement, dans le cinquième chapitre, en conclusion, nous réexaminons la plus grande part des plans et maquettes présentées aux chapitres précédents qui pourront être examinés cette fois à la lumière de nos propositions. On constatera qu'une partie importante de nos exemples concernent la conception de logements et de parties critiques d'iceux: cuisines, salles d'eau, ce genre de fonctions: nous sommes convaincus que l'architecture formalisée doit se donner pour but de résoudre avant tout des problèmes pratiques. Enfin, c'est très délibérément, que nous avons, dans le cadre de cette thèse, décidé de placer notre contribution personnelle avant l'histoire du domaine, qui n'a jamais cessé de figurer en arrière-fond de notre travail.We propose a methodological framework of architectural design which uses operations and tools of artificial intelligence: we propose, in this study, to materialize an a priori imaginary and global architectural space by primarily local operations of instantiations and reifications of cellular design. The Architect Space (AS) is an imaginary space. The building to which this space can corresponds, being quite real, is a material transcription of the properties of this AS, and also the resultant of constraints, choices, and physical and social pressures. This resultant is the achievement and the effect of operations gathered as a structure. These operations, which are equipped with formal and algorithmic properties, constitute the tools for materialization of an AS. The operative structures, considering the complexity of the imaginary AS to materialize involve as for now a data processing of modeling and optimizations which concerns clearly the artificial intelligence today: heuristics, monte-carlos, artificial selections and evolutions, multi-agents. We propose a repertory and an ordering of these methods and their applications to the architectural design. We examine on this occasion the aspects of the history of architecture which carry out logically towards our approach. In the introduction, we present the problematic (origins, goal, limits and uses) of the proposed method. In chapter 1, we present a multi agent system, supported by an evolutionary method. In chapter 2, we describe an architectural interface, which interposes between the multi agent system and the Architect user. In chapter 3, we describe the principles of history of theory of architecture. In chapter 4, we answer the question "why Architect needs the concepts and methods of the artificial intelligence?", by briefly traversing the associated theories, methods and application. Finally concluding, in chapter 5, we re-examine the greatest part of the plans and models presented at the preceding chapters which could be examined this time in the light of our proposals. One will note that a significant part of our examples relate to the design of residences and their critical parts: kitchens, bathrooms, this sort of functions: we are convinced that formal architecture must aim to solve the practical problems above all. Finally, it is very deliberately, that we have decided, within the framework of this thesis, to place our personal contribution before the history of the field, which never ceased appearing in innermost depth of our work.ST DENIS-BU PARIS8 (930662101) / SudocSudocFranceF
