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
Perceptions et changements d’usages de zeb a pik (Neurolaena lobata et espèces affines) à la Martinique
Full text linkCette enquête ethnobotanique vise à décrypter, de façon diachronique et synchronique, les modalités d’inscription de l’espèce Neurolaena lobata (L.) Cass. dans la pharmacopée martiniquaise (pratiques de soin et connaissances associées) et les représentations populaires qui lui sont liées. Nous nous intéressons également au complexe d’espèces qui partagent le même nom vernaculaire (zeb a pik) afin de contribuer à clarifier la compréhension de ces usages de phytothérapie singuliers. Enfin, les phénomènes de visualisation médiatique et d’engouement populaire dont ont bénéficié les zeb a pik durant la récente période de pandémie font également l’objet de cette étude.This ethnobotanical survey aims at deciphering, diachronically and synchronically, the ways in which the species Neurolaena lobata (L.) Cass. is included in the Martinican pharmacopoeia (care practices and associated knowledge) and the popular representations associated with it. We are also interested in the complex of species that share the same vernacular name (zeb a pik) in order to contribute to a clearer understanding of these singular herbal uses. Finally, the phenomena of media visualization and popular infatuation that zeb a pik enjoyed during the recent Covid-19 pandemic period are also the focus of this study
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
Effects of feeding increased levels of heat processed rapeseed meal on performance of broiler chicks
No full textA six week feeding trial was conducted involving day-old male broiler chicks to study the effect of increased levels of untreated and heat (105 degreesC/15 minutes) treated RSM (variety Pak-cheen, glucosinolate content 60.85 mug/g) on growth performance of these chicks. Chicks were divided. into seven groups, each replicated three times, with 8 chicks in a replication. One group was fed on standard commercial diet without rapeseed meal, three groups were given diets containing 15, 20 and 25% rapeseed meal, while another three groups were fed on diets containing 151, 20 and 25% heat treated rapeseed. All dietary treatments did not effect significantly feed consumption (45.1 to 61.6 g/chick/day). Effect on weight gain was significant (P < 0.01). Highest average daily weight gain (30.91 g/chick) was recorded in the standard diet group. This however, was not significantly different from average daily weight gain in 15% untreated RSM fed group (29.7 g/chick). All other RSM groups showed significantly (P < 0.01) lower weight gain values than the standard diet group. Feed to gain ratio ranged from 1.70 to 2.24 among various dietary treatments. The feed economy was highest in 20% treated RSM diet group which consumed 1.70 kg of feed per kg of weight gain. This was followed by the 15% treated RSM fed group (1.71). Dressing percentage was not influenced by different treatments. Similarly, differences in liver, gizzard and heart weights were statistically non-significant. Heat processing of rapeseed prior to oil extraction may result in the inactivation of myrosinases, leading to reduction in the anti-nutritional effects of glucosinolates. This effect may not have been important in the present study, because initial glucosinolate content of the feed was 9.12 mug/g in 15% RSM diet which was below the threshold. On the other hand damage to protein, in terms of loss of amino acids due to heating, seems to have led to the inferior nutritional quality of the feed
