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

Exploring remanufacturing conveniency: An economic and energetic assessment for a closed-loop supply chain of a mechanical component
No full textThe concept of sustainability has become pervasive in society, compelling industries to embrace circular economy principles supported by institutions, such as the European Commission. The circular economy promotes recovery, sharing, and recycling, which poses challenges in transitioning from linear to circular models. Remanufacturing is a key strategy in this framework by enabling the recycling of discarded products, improving resource efficiency, and reducing waste. Therefore, this study investigates the key factors influencing decision-making in remanufacturing processes within the supply chains of mechanical components, identifying scenarios where remanufacturing proves to be more effective than purchasing new products. This research provides valuable insights for businesses considering the adoption of remanufacturing in their supply chains. While previous studies on remanufacturing have predominantly focused on economic aspects, this research addresses both economic and energy-related implications. The study proposes a three-stage methodology to compare three scenarios and select the optimal one: a traditional supply chain for mechanical components without remanufacturing (Scenario 1), a supply chain with remanufacturing and direct customer-manufacturer interaction (Scenario 2), and a supply chain with remanufacturing and indirect customer-manufacturer interaction facilitated by a distribution center (Scenario 3). This methodology was applied to components made of steel, aluminum, and titanium. The results reveal that the remanufacturing volume and the percentage of material preserved by conventional manufacturing process are the most critical variables to consider when evaluating the introduction of remanufacturing in supply chains. Specifically, the lower the former values the more remanufacturing tends to be preferred. Furthermore, remanufacturing is usually favored by the energetic analysis, while the economic analysis shows mixed results. The developed models and the obtained findings could assist organizations in making strategic decisions regarding end-of-life strategies and assessing the economic and energy viability of integrating remanufacturing processes into their supply chains, as opposed to favoring new component production
