A new point of view on Product Lifecycle Management
No full textThis paper is one of the first tasks that the members of the International Working Group on Product Lifecycle Management (PLM-IWG) assigned themselves in November 2007 for establishing a comprehensive point of view on PLM. In particular, the present paper aims to capture the state of the art of PLM from the PLM worldwide community. The generic models presented here can be translated and put into practice in each company considering the structure of the company and the characteristic of its products. The paper is still under development in view of reaching consensus on the meaning and the scope of the PLM area, therefore every contribution is welcome
Integrating Eco-design and PLM in the Aviation Completion Industry: A Case Study
Get PDFAviation represents 12% of the CO2 emissions from all transport sources in the world. These pollutants are even stronger in their impact because they are released at high altitudes. Therefore, aeronautical companies have adopted the eco-design and PLM perspective to integrate the environmental concerns into the development of their products. PLM permits to include the environmental matters into every phase of the development process, not forgetting traditional arguments such as function, costs, production and aesthetics. Research regarding ecologically concerned textiles in aviation completion industry is not available in literature, especially those regarding its whole lifecycle and supply chain. Therefore, this paper aims to analyse this unexplored concern by assessing the integration of eco-design and PLM perspective for the use of textile materials in this industry sector. Through a case study, the research team explored the completion function of a north-American company in general and, specifically, the use of textile materials for internal completion of the aircraft. Even though representing 1% of the total weight of the aircraft, textiles represent an important factor in the composition of an airplane and the fact that it is being thought off as another recyclable and not disposable part of it should mean a shift in the perception of its growing importance in the development of the plane as a whole

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
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
