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
Switching to bio-based packaging for organic products: supply chain actors’ perspectives
Full text linkThe use of fossil-based plastics used for packing organic foods is under the lens of the organic movement because of the contrast with the organic farming principles and its negative impact on the environment. Bioplastics, which can be bio-based and biodegradable, are a promising solution to address the various issues, i.e. social and environmental, caused by the intense use of conventional plastics. Nevertheless, using bioplastics as a more sustainable solution in the food packaging industry is still controversial. It involves a variety of opinions, consensus, and disagreements among food supply chain actors. The present study investigated stakeholders’ viewpoints regarding the acceptance of bio-based packaging in the Italian organic food supply chain. Individual perspectives from a selected group of organic stakeholders (producers, distributors, and researchers) were captured by applying the Q methodology. Two relevant divergent views were identified, as well as consensus agreements. The study shows how Q methodology can effectively discover the most relevant viewpoints about an emerging topic

No full textExploring Visitors’ Visual Behavior Using Eye-Tracking: The Case of the “Studiolo Del Duca”
Full text linkAlthough the understanding of cognitive disciplines has progressed, we know relatively little about how the human brain perceives art. Thanks to the growing interest in visual perception, eye-tracking technology has been increasingly used for studying the interaction between individuals and artworks. In this study, eye-tracking was used to provide insights into non-expert visitors’ visual behaviour as they move freely in the historical room of the “Studiolo del Duca” of the Ducal Palace in Urbino, Italy. Visitors looked for an average of almost two minutes. This study revealed which parts of the artefact captured visitors’ attention and also gives interesting information about the main patterns of fruition
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
Exploring edible insects’ acceptance through subjective perceptions: a visual Q study
Full text linkThe practice of eating insects, known as entomophagy, is part of a regular diet for millions of people in Asia, Latin America and Africa. However, the use of insects as food is relatively new in Western countries. The present paper explores the willingness to adopt edible insects as food among Italian consumers using Q methodology. A sample of ‘experts’ (e.g. entomologists) and ‘non-experts’ (e.g. students and other researchers) formed the participant sample (P sample). Participants were asked to rank-order a set of 36 images of food dishes prepared using insects (Q sample). Results showed that visual appearance plays an important role in influencing consumers acceptance of insects as food. The Q analysis identified three distinct viewpoints or consumer profiles: Factor 1 ‘The Traditionalist’; Factor 2 ‘The Fast Food Addicted’; and Factor 3 ‘The Insectivore’. This study confirms that visible insects in food may be problematic for the more traditional viewpoint, while results for the other two factors identify possible avenues for better communicating insect-based food
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
