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
Nutritional scores of milk and plant-based alternatives and their difference in contribution to human nutrition
Full text linkMilk consumption is in decline in developed countries due to changes in lifestyle and habits. Such a reduction is partly due to the expanding plant-based industry which provides attractive alternatives. In this study, the nutritional composition of soya, oat, almond, coconut, and rice-based beverages was compared to that of cow and goat milk by means of 4 commercial nutritional scores (NS). Contribution to the recommended daily intake (RDI) of macro- and micro-nutrients was calculated for comparison. Apart from soya, plant-based beverages (PBB) did not approximate the nutrient profile of cow and goat milk, e.g., they did not provide iodine and contained only limited amounts of calcium, potassium, and magnesium. For several traits important for human health, oat, almond, coconut, and rice-based beverages scarcely contributed to the RDI. Depending on the criteria considered for the score calculation, however, certain PBB achieved better NS than milk. Findings show the difficulty in ensuring coverage of RDI through a non-guided inclusion of PBB as a substitute for milk. Moreover, the inferior contribution of PBB to RDI compared to milk and the high variability in the nutritional scores between the different PBB brands prompts for a standardisation across the plant-based food industry to increase transparency
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
Detailed characterization of plant-based burgers
Full text linkFlexitarians have reduced their meat consumption showing a rising interest in plant-based meat
alternatives with ‘meaty’ characteristics, and we are witnessing an unprecedented growth of meat
substitutes in the Western market. However, to our knowledge, no information regarding the
‘simulated beef burgers’ nutritional profle compared to similar meat products has been published yet.
Here we show that, whilst both plant-based and meat-based burgers have similar protein profle and
saturated fat content, the former are richer in minerals and polyunsaturated fatty acids. We found that
the most abundant minerals in both categories were Na, K, P, S, Ca, and Mg; being Na and S content
similar between groups. Only six amino acids difered between categories, being hydroxyproline
exclusively in meat-based burgers. Plant-based burgers revealed fourfold greater content of n-6 than
meat-based burgers, and greater short-chain fatty acids proportion. Our results demonstrate how
‘simulated beef’ products may be authenticated based on some specifc nutrients and are a good
source of minerals. We believe that there is a need to provide complete and unbiased nutritional
information on these ‘new’ vegan products so that consumers can adjust their diet to nutritional
needs
