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
Towards more sustainable animal-feed alternatives: A survey on Spanish consumers' willingness to consume animal products fed with insects
Full text linkGlobal meat consumption will continue to increase in response to the growth in population and demand. Numerous studies have emphasized the nutritional, economic, and environmental benefits of using insect meal as an alternative protein source for animal feed. This article analyses Spanish consumers' willingness to consume pork, chicken, eggs, and fish, and explores the effect of sociodemographic and psychometric characteristics on their willingness to consume when the animals are fed with insect protein as a sustainable feed alternative. The study used an online Spanish consumers' panel belonging to Qualtrics© (market company services) and distributed it to 1260 individuals stratified by age, gender, and region. The data were analysed using the non-parametric Kruskal–Wallis and Mann–Whitney U tests. Overall, the results demonstrated that most Spanish consumers expressed high uncertainty regarding their willingness to consume animal-fed insect meals. They also exhibited moderate levels of food neophobia and showed a highly ecocentric attitude. The non-parametric comparison analysis confirmed significant differences in willingness to consume sustainable animal products across sociodemographic characteristics: financial situation and gender were significant variables, with females more willing to consume sustainable animal products than males. For the psychometric traits, significant differences in willingness to consume sustainable animal products were confirmed across food neophobia, food neophilia, opinions on using insects in animal feed, and ecocentric attitude. The results also confirmed a significant difference in the effects of sociodemographic variables on psychometric attributes. Financial situation affects food neophilia, anthropocentric attitudes, and opinions on the use of insects in animal feed. Age influences food neophobia, ecocentric attitudes, and opinions on the use of insects in animal feed. Education also influences food neophilia, ecocentric attitudes, and opinions on the use of insects in animal feed. For gender, it is observed that females are more neophobic than males. This study has provided comprehensive initial insights into consumer willingness to consume insect-fed animal products in Spain, and the findings from this study will serve as a valuable resource for producers, policymakers, and governments in making informed decisions that promote more sustainable production practices.This study has received funding from the Spanish Research Agency (AEI) under grant agreement No PID2019-111716RB-I00 (project acronym SUSPROMO).

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
Meta‐Analysis of Consumer Willingness to Pay for Short Food Supply Chain Products
No full textAbstract Due to their perceived benefits for health, the environment, the economy, and sustainability, in recent years there has been a growing interest on the part of researchers and policymakers in short‐food supply chains (SFSCs). However, a systematic review of the literature on this topic remains lacking. To address this gap, the study conducts a meta‐analysis to examine consumer willingness to pay (WTP) for SFSC products, taking into account various sociodemographic factors and sustainability attributes. On average, consumers are willing to pay a 34.5% premium for SFSC products. Key factors influencing WTP include gender, education, study year, age, region, product category, and sustainability attributes. Women exhibit higher WTP, and individuals with higher education levels also demonstrate increased WTP. Notably, WTP for SFSC products is lower before 2014, while younger consumers exhibit higher WTP overall. Consumers in Western Europe present higher WTP estimates compared to those in North America and other regions. In terms of sustainability attributes, organic products receive the highest WTP, with food categories such as meat, poultry, dairy products, and honey showing the highest estimates. These findings offer valuable insights for SFSC producers, marketers, and policymakers, guiding effective strategies to promote SFSC products within sustainable agri‐food systems
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
