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

Understanding consumer behaviour and preferences for organic food products in developing markets: A theoretical framework
Full text linkOver the past few years, both consumers and researchers have given much attention to an increasing demand for organic food products around the world. While the motivation and barriers of consumers in mature markets are thoroughly examined, there is a great deal still to be understood about consumer behaviour in emerging markets. In contrast to developed markets in which various factors, such as taste, product quality, safety and environment concerns influence consumer choice, there is a strong emphasis on the motivation of health. This insight has shown the need to appreciate more complex aspects of culture and societal context, which influence consumer behaviour in emerging markets. The current literature is predominantly confined to Europe and North America, despite the increasing demand for organic food products in emerging markets. The influence of these factors is that consumers' attitudes, e.g. purchases and particularly organic foods, do not correspond to the exact level of appropriate behaviour. A potential buyer having a positive attitude toward organic food does not necessarily leads to a purchase. Research carried out in the Asian countries: China, Thailand and India also revealed an important role played by health and safety as a reason for buying organic foods. The health aspects of organic foods, which are the most frequently used reason for buying those products, have been shown to play an important role in many studies into why consumers buy these products. Health is determined largely by internal motivation, such as feeling better about preventing illness and having a healthy body image, but also the social factors that act as external factors e.g., peer pressure to eat organic food, are the main reason for purchasing organic foods. Developing markets in the US and Europe have been a primary focus of previous studies on the consumption of organically produced products.

Paper type: Theoretical ResearchLes recherches sur l’appréhension du comportement du consommateur vis-à-vis des produits biologiques ont apporté des éclaircissements par rapport aux principaux déterminants et facteurs prédicateurs permettant de mieux comprendre le comportement du consommateur vis-à-vis des produits biologiques en donnant naissance à une série de controverses et de résultats divergents. Alors que les motivations et les obstacles des consommateurs dans les marchés matures sont largement examinés, il reste encore beaucoup à comprendre sur le comportement des consommateurs dans les marchés émergents. Contrairement aux marchés développés où divers facteurs, tels que le goût, la qualité des produits, la sécurité et les préoccupations environnementales influencent le choix des consommateurs, il existe un fort accent mis sur la motivation de santé.
La littérature actuelle est principalement limitée à l'Europe et à l'Amérique du Nord, malgré la demande croissante de produits alimentaires biologiques dans les marchés émergents. L'influence de ces facteurs est telle que les attitudes des consommateurs, par exemple les achats et en particulier les aliments biologiques, ne correspondent pas exactement au niveau approprié de comportement. Un acheteur potentiel ayant une attitude positive à l'égard des aliments biologiques ne conduit pas nécessairement à un achat.
Les recherches menées dans les pays asiatiques tels que la Chine, la Thaïlande et l'Inde ont également révélé un rôle important joué par la santé et la sécurité en tant que raison d'achat de produits biologiques. Les aspects sanitaires des aliments biologiques, qui constituent la raison la plus fréquemment citée pour l'achat de ces produits, ont été démontrés comme jouant un rôle important dans de nombreuses études sur les raisons pour lesquelles les consommateurs achètent ces produits. La santé est largement déterminée par la motivation interne, tels que le sentiment de mieux se protéger contre les maladies, mais aussi les facteurs sociaux agissant comme des facteurs externes, par exemple la pression des pairs pour consommer des aliments biologiques, sont la principale raison de l'achat d'aliments biologiques.
