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
Whaling in the High Seas - Conservatory obligations and customary law
Get PDFThis thesis examines what conservatory obligations there are on whaling in customary law and international sources. The focus is on high sea whaling and the main international laws on the high sea concerning living resources and the main whaling conventions. The exploitation of marine mammals is regulated by the United Nations Convention on the Law of the Seas, the Convention on Biological Diversity and the Convention on International Trade in Endangered Species of Wild Fauna and Flora. These conventions obligate states to cooperate and take conservatory measures in order to avoid whales from being over-exploited. The specific whaling conventions, the International Convention for the Regulation of Whaling and the North Atlantic Marine Mammal Commission, have different views on how to conserve whales and set different obligations. The International Convention for the Regulation of Whaling have set a moratorium which bans all commercial whaling. The customary law on whaling is not easy to determine. There is probably customary law on the obligation for states take conservatory measures and to cooperate with each other and in appropriate international organizations. How far this customary law stretches is not certain. Some states argue that the moratorium is customary law, but it is unlikely that obligations of the customary law stretches that far
The EU regulation on organic production and labelling - development and future of the organic framework
Get PDFThis thesis paper studies the organic legislative framework in the European Union. It describes how the EU organic regulation has developed and discusses the future trends, issues and opportunities of the organic movement. It researches how organic is regulated in the EU today, what its’ objectives and aims are, what issues and improvement exist and how the organic movement will develop in the future. The focus is on the organic regulation in the EU and the method used is a discussion paper on legal reform, de lege ferenda. The facts will be presented chronologically and end in a discussion and conclusion. Organic agriculture is a holistic production management system that promotes sustainable production methods. The organic label is a market tool that informs consumers about the production of the product, such as environmental performance and impact. Organic seeks to protect natural resources, ecosystems and biodiversity and restricts the use of chemicals and pesticides. It protects rural development, fair competition, the stability of the organic market. It is a market tool that aims at resolving the market failures that are a consequence of information asymmetries regarding products environmental costs. The first EU regulation on organic production was established in 1991, and the current regulation was adopted in 2007. In 2014 the regulation was proposed to be reviewed and a preliminary agreement was reached in 2017. The organic agriculture and frameworks have developed rapidly in recent years and new organic concepts on how to regulate organic production are being formed in the international organisations. It is unclear if the EU will follow this international development of more flexible regulations in the future. The EU organic regulation have been stuck on arguments on detailed rules and consensus was hard to reach. The EU have a good opportunity to be a leader in the field of organic production and labelling however the long review process might have made the EU regulation become out-of-date too quickly
