Standardisation in IT-based procurement in non-hierarchical networks
No full textThis chapter deals with communication aspects in non-hierarchical manufacturing networks and how standardized electronic data interchange (EDI) can contribute to overcoming the respective shortcomings of characteristic non-hierarchical supplier relationships. Generally, information technology (IT) has a great potential to improve business processes. The chapter first identifies different IT-based solutions in machine tool industry for supporting the procurement process. Then, the chapter presents necessity of standards for secure communication in non-hierarchical networks. It describes the general requirements of electronic business processes regarding secure messaging and archiving in non-hierarchical production networks, and provides examples of the state of the art to tackle these requirements. The chapter addresses four main aspects-authenticity, integrity, confidentiality and non- repudiation. Similar topics, such as different types of electronic signatures and storage issues are also discussed
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
Étude des activités collaboratives de conception en tant que situation d'apprentissage : application à l'ingénierie des produits et à l'ingénierie didactique
No full textCette thèse aborde la problématique de la génération des connaissances au cours de la phase de conception et plus particulièrement en conception collaborative. Il est proposé d'exploiter les connaissances en conception après une phase de collecte, de capture. Après une phase de capitalisation viendra une étape de réarrangement de ces connaissances. Un processus appelé "Processus d'Ingénition" est montré. Établi sur le principe de description de graphes de connaissances augmentées d'une triple instrumentation, ce processus permet une analyse originale des phases de conception d'un produit. Des applications à l'ingénierie didactique et à l'ingénierie pédagogique ont vu le jour au cours de ce travail. Les domaines de la conception collaborative de produits, de la didactique et de la gestion des connaissances sont mis en regard pour proposer une vision originale du processus de conception collaborative.This thesis deals with knowledge generation problems during product design and more particularly in collaborative design. By integration of thee fields, collaborative product design, didactic engineering and knowledge management, we propose a generic framework. The main proposition is to capture, capitalize, reorganize and then exploit the knowledge in the field of design product. In the first step we develop a conceptual framework as “process of ingenition”. This global process allows defining the macro level positioning. In the second step the graph of knowledge description with a “triple instrumentation” developed. This process leads to have an original analysis of product design. At last we submit an application of proposed process in didactic and teaching engineering
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
