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
European Innovation Partnership on Raw Materials - Annual Monitoring Report 2019
Full text linkThe Annual Monitoring Report 2019 assesses the progress made by the European Innovation Partnership (EIP) on Raw Materials, namely by providing an overview on the state-of-play of Raw Material Commitments (RMCs) of the EIP on Raw Materials. Commitments are joint undertakings by several partners, who commit themselves to carrying out activities that contribute to achieving actions, targets and objectives of the EIP. It is based on indicators that measure inputs (human resources, funding, etc.) and outputs related to the commitments.
The Annual Monitoring Report 2019 shows that the EIP currently counts 35 Raw Materials Commitments, which include around 400 partners. Taken together the Commitments have reported a total indicative budget of close to €2 billion. They are found to be delivering tangible results such as innovative actions or pilots, and strategic documents.

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

Life cycle assessment (LCA) of food and beverage packaging
Full text linkLAUREA SPECIALISTICAL’industria alimentare è strettamente legata all’industria del confezionamento, perchè permette la protezione dei prodotti ed il loro trasporto verso i consumatori. Il packaging multi materiale è uno dei più comuni tipi di confezionamento ed è solitamente utilizzato per prodotti liquidi come latte, succhi di frutta, vino. Il packaging multi materiale genera potenziali impatti negativi per l'ambiente nel suo ciclo di vita. Negli ultimi anni, i maggiori produttori di packaging multi materiale stanno utilizzando il Life Cycle Assessment (LCA) come strumento per analizzare le prestazioni ambientali dei loro sistemi di confezionamento. In questo lavoro, dodici studi di LCA su packaging multi materiale sono stati analizzati per ottenere un quadro generale della attuale prassi LCA in questi sistemi. I potenziali processi comuni per il packaging multi materiale sono stati riassunti. Questi includono l'estrazione e la produzione di materie prime, la produzione di imballaggi, la fase di riempimento, la fase di fine vita, il trasporto. La produzione di materie prime e la fase di fine vita sono risultati essere le fasi più impattanti del ciclo di vita del packaging multi materiale. Gli studi LCA esaminati hanno affrontato limitazioni in termini di qualità dei dati e affidabilità, di definizione dei confini del sistema, e di questioni metodologiche come la scelta delle categorie di impatto e la procedura di allocazione. La complessità e la soggettività nella realizzazione di uno studio di LCA può produrre risultati discutibili. Un approccio di LCA semplificato utilizzando una metodologia standardizzata potrebbe essere oggetto per futuri sviluppi.Food and beverage industry is tightly bound to packaging industry to enable the protection of products and to transport them safely to the consumers. Multi material packaging is one of the most common packaging type and is usually adopted to contain liquid products like milk, juice, and wine. Multi material packaging generates potential adverse impacts to the environment over its life cycle. In recent years, the major multi material packaging producers have been utilizing Life Cycle Assessment (LCA) as a tool to analyze the environmental performance of their packaging systems. In this work, twelve LCA studies on multi material packaging were reviewed to get a general picture of the current LCA practice in these systems. The common potential processes in multi material packaging were summarized. These include the extraction and production of raw materials, the production of packaging, the filling phase, the end-of-life, transportation. Raw materials production and end-of-life were found to be the most impacting phases in multi material packaging life cycle. Examined LCA studies faced limitations in data quality and its reliability, in the setting of system boundaries, and in methodological issues like the choice of impact categories and allocation procedure. The complexity and subjectivity in carrying out an LCA study might yield arguable results. A simplified approach to LCA using a standardized methodology could be a subject for future development
